Abstract
The invention concerns a spray pump (3) capable of being actuated by a hand lever, to be mounted on dispensers (2) or the like. Said pump comprises a piston pump (6) capable of sliding linearly in a pump chamber (7) on the housing side. Said piston is connected, on the rear side of an outlet (9), to the hand lever (5) and returns to its base position urged by a spring. The invention aims at producing a pump which is both simple and reliable by associating two articulating parts (I, II) with the lever (5). One (I) of said parts is located so as to slide in a linear slider on the housing side, and the other (II) is fixed to the housing, on the side opposite the outlet (9), such that the two articulating parts (I, II) are connected by mutually collapsible contiguous parts (a, b).
Description
Nose-02-98 04:12P NQllos Translations, INC. P.03 , lever-oaerated Sorav Pum Ttte invention relates to a hand lever-operated spray pump, particularly for the purpose of attaching to bottles or similar, having a pump plunger that moves linear in a pump chamber on the housing side. The pump plunger is connected with the hand lever at the rear of a mouth piece opening and the pump plunger returns to the starting position as a result of a spring loading.
A spray pump of this type is specified in US-PS 4,955,511, where the hand lever is a trigger lever which is rigidly connected with the pump plunger. This causes a tendency for the pump plunger pump chamber unit to tilt.
US-PS 3,7213,442 specifies a hand lever-operated spray pump whose hand lover is arranged on a pivoting bearing by means of a fork recess / peg engagement on the housing side. Separated by a space thereto, it acts via a living hinge in conjunction with a transmitting part provided on the upper side acting upon the pump chamber, which Is a bellows-type pump in this case. The transmitting part is connected to the housing on the side opposite to the mouth piece by means of an additional living hinge. A finger on the transmitting piece closaslopens an air compensation opening.
It is the object of the invention to provide a hand levee operated spray pump of the shove type which is functionally r~elfable and structurally simple.
This problem is solved substantially with a hand lever operated spray pump having the characteristics of Balm 1, provided that two hinge points are allocated to the hand lever Nov-02-98 04:12P Nell~s Translations, INC. P.04 one of which is moving non-rotating on the housing side in a linear guide provided on the housing side, and the other is attached to the housing on the side opposite to the mouth piece in such a way that both hinge points are connected via~ero brjs(o_e ~ectionQ ~~at buckle with respect to each other. Thisprevents t,e lau_m_hnlunger from tilting. The hand lever performs an overriding movement: swiveling plus shifting. The respective linear guide is defined by the guide on the housing side. The resulting convergence of the two hinge points is compensated simply in that the bridge sections buckle or fold. This movement can even be utilized as a force for restoring th~"pumo I umler to its staAlng oosition by means of a hand lever couenng. The bridge sections' buckling movement may then be utilized for an additional function in that one bridge section supports the sealing part for a ventilation aperture which leaves its seating position with rospect to the ventilation aperture during the buckling process. This solves the problem of air compensation by the easiest possible method. As the buckling process takes place only when the pump is activated, this provides for a space-saving outline in non-operating position, offering both storsge and packaging advantages. According fo the subJect matter of US~PS 3,726,442, the overall size of the spray pump decreases only when it is adlvated. In addition, the invention pro sea to rovide a livin hin a point between the two brid a tlons, thereby eliminating the need for classic axes. The sewn r ge sec ion is then further developed such that it represents the connector on a U-profiled part that encompasses the housing in a U-shape. This provides a strong coupling for the bridge.
Nov-02-98 04:12P Nalles Translations, INC. P.05 In addition, the design is characterized by a locking connection from the U-profiled part toward the housing. In order to prevent that this locking point is required for the purpose of achieving the required flexibility for the respective bridge section, the hinge point, located on the side of the spray pump opposite to the mouth piece, is a living hinge adjacent to the place of the locking connection. This also prevents any movements caused by the bridge sections' movement to be transferred to said place. In addition, a proposal is made, which has its own significance, according to which the pump plunger continues tapering approximately up to the mouth piece where it is in form-fit connection with a mouth piece cap and that, between the two parts, s discharge valve is provided in the form of a moldable nrbber piece. This represents a structural simplification, allows easy assembly and requires fewer parts. The rubber piece is of the type which remains closed until a certain high pressure response threshold is reached at which time it opens abnrptly. This results in a powerful spray, especially if the rubber piece is mounted on the front end of the pump plunger and is equipped with a collar which expands as a rosult of the prossure caused by the Huid, and if it has axial flow-Ihrough cross sections in a disk-shaped part.
These cross sections are connected with the mouth piece opening in that the mouth piece cap is rotated. This should be based on eccentricity in order for the spray pump to be superior with respect to media losses as well. It is advantageous if the spray pump housing is attached to the bottleneck by means of a plug-inlclip connection substituting the normally used swivel nut. With the attachment of a collar, the plug-in connection is able to simultaneously function as a sealing connection.
Nov-02-98 04:12P Nallas Translations, INC. P.06 In addition, the spray pump as per the invention is characterized by a disk-shaped inlet valve having a valve locking piece which is supported by crosspieces. The pump plunger restoring spring is supported by said crosspieces. The opposite end of the spring moves against a cross section-decreasing shoulder in the interior of the hollow pump plunger which trails on the wall of the pump chamber with the edge of the larger cross section opening. This edge is preferably a sleeve-like lip. It is also advantageous to equip the pump plunger with lateral pockets for the hinge point on the hand lever side. The hand lever axle stubs passing through the linear guide are inserted in the pockets. An advantageous variant of an air compensation system is the utilization of the pump plunger. According to this variant, the hou ' y wall of the ump chamber ~nrnvided with a ventilation aEerture extendin4 into ~,h.~.jnt~fiQS.of the boUle~.St)Lhali~e pump is in its starti_ngr~.siti_Qn_~the apertu~e~ which_is.located directly_behind the edge of the"eump plunger, is closed h~e..pirt~p.ptungef~,and op~n;s. when. the pump pl~~g~~is activated. This provides for an additional pump plung~~er function. It acts as a slide. his doss not even require sin well is co ~uslyr leading. It s,gffices to equip the pump elun ~er ~with two pislon rings hich in t a ~m~c~plunoer startin~a position, are located on either side~e m ilation aperture. This decreases the friction against the pump plunger and favors the desire easy ac vation of the trigger pump. There is an added advantage in that, as a result of creating the ring space, the pump plunger, positioned in the direction of discharge, acts as a seal with relation to the pump chamber, for example in the event of excess pressure in the bottle which may be generated by heat.
Nov-UZ-9S U4: 1,31 N~ I les I tans lations, INC. P.07 An advantageous further dwelopmenl should be noted with respect to the inlet valve. This development is achieved by a disk-shaped inlet valve body which is symmetrical with relation to the disk center plane. The respective mirror symmetrical loan permits the use of either side of the inlet valve body, thereby preventing any assembly mistakes or re-work requiring that a side inverted inlet valve be reversed. Regardless of ils allocation, the desired valve function is always reliable. It is also advantageous for the valve locking body of the inlet valve to be barrehshaped having hemispherical ends on both sides. The valve locking body is located in the center of the disk-shaped inlet valve body. Furthemnore, the discharge valve is also further developed which is characterized in that the discharge valve is covered by the mouth piece cap and that il is equipped on the fore-part with supply channels leading toward the mouth piece opening. The supply channels can be closed by rotating the mouth piece cap. This is achieved in that the discharge valve is a moldable rubber piece which is equipped with a stem. One end of the slem supports a valve disk while the other end is equipped with a cylindrical stopper part having diametrically opposed flattened parts that ueate channels. Supply channels lead from the front of the flattened parts to a central swirl chamber. Due to its larger mass of material the stopper part is virtually not moldable so that the channel cross sections remain largely unaffected despite the pressure caused by the media, while the valve disk provides the flexibility and re:toting force required for the valve function.
Nov-02-98 04:13P NollQS Translations, INC. P.08 For the purpose of locking it is advantageous for the swirl chamber to be eccentrical, resulting in a congnrent position with the mouth piece opening, which is also eccentrical, and the ability to leave this position which results in blocking the discharge path. Finally, with rasped to the axis of the second bridge section, it is proposed to use a hook for the locking connection on the housing side for the second buckling bridge section. The hook is adjacent to a supporting crosspiece whose front surface forms the hinge point in that it is thrust against a housing console at the rear.
It is structurally advantageous for the hook to pass through a hole in the rear housing console, and that the supporting crosspiece, which is located behind the hole and which croates the hinge point and runs substantially parallel with the shaft of the hook, forms the end of the second buckling bridge section. The close proximity between the supporting crosspiece and the hook provides for sufficient play to allow the bridge sections to buckle. Added to that is the flexibility and restoring force of the material used, i.e. synthetic material.

A spray pump 3 is allocated to the neplc 1 of a bottle 2. It is a so-called trigger pump, representing a standing unit in the form of a dispenser for dispensing a powerful spray.
The core of the spray pump 3 is the housing 4, which extends in the manner of a hammer head transverse to the neck 1 which is substantially vertical. The neck 1 is grasped to provide counter support. A hand lever 5, projecting toward the underside of the housing 4, is located in the range of action of a respective holding hand.
The hand lever 5 swivels about a horizontal first hinge point I of the activation mechanism, i.e, it is pulled agaMst the neck 1. This takes place against a spring loading which, upon release, aMraya returns the hand lever 5 to the starting position as shown in Fig. 3.
Nov-02-98 04:14P NallQS Translations, INC. P.10 The activation position is shown in Fig. 3 with dash~dot lines.
The hand lever 5 is coupled to a pump plunger 6 which moves in a pump chamber T that forms a pump cylinder.
The connection between the hand lever 5 and the pump plunger 6 is such that the hand lever 5, in addition to the above mentioned swiveling movement, shifts linear in the pump chamber together with the pump plunger 6. The respective displacement acts against the expansive power of a pump plunger restoring spring t3 which is located in the pump space. This spring is a threaded pressure spring.
The overriding movement made by the hand lever 5 is realized via a linear guide on the housing side. Longitudinal slits 10 begin at the tube-shaped end of the housing 4.
This end faces the mouth piece opening 9 of the spray pump 3. The longitudinal slits 10 are open toward the front edge of the tube and extend diametrically in Longitudinal diroclion. Their horizontal depth defines the operating stroke in that the axle stubs 11 of the hand lever 5 which create the physical hinge point I move against the interior slit bottom 12.
The axle stubs 11 traverse the longitudinal slits 10, which are arranged in pairs, and at the end they engage in respective pockets 13 provided on the two longitudinal sides of the pump plunger 6. This results in driving the pump plunger 6 in the sense that the volume of the pump chamber 7 decreases.
Nov-02-98 04:14P N~IIQS Translations, INC. P.11 The hand lever 5 is connected with the housing 4 by means of a link chain. In actuality, this is achieved in that two hinge points are allocated to the hand lever 5, the abovo montioned hinge point I and a second hinge point, designated with II, which is located on the side of the pump housing 4 opposite to the mouth piece opening 9.
The two hinge points I, II are connected by means of twe bridge sections a b that buckle with relation to each~er. The buckling position is seen in Figs. 2 and 3. In order to permit the bridge ~._ sec ns a, b to buckle respectively opposite to the housing 4, they are connected vita hinds ~omt 15 hrch may be a living hinge. The respective V-notch 15' continues into the cheek-like -~~[~~,~~ 16 of the cap-like bridge section b and also into the shield-like root section ~Torthe hand lever 5. The coaxially oriented axle stubs 11 are attached to the insides of the root section 17.
Consequently, the bridge section b which changes to the substantially vertical side walls 16 is U-shaped.
In contrast, the root section 17, which is attached to the bridge section a and represents a part thereof, is closed toward the grip section of the hand lever 5 allowing the tube-shaped end of the housing 4 to pass freely. This provides a plug-in hole 18 for the purpose of assembly.
The bridge section designated with b supports a locking part 19 which tightly seals a congruently positioned ventilation a~etiure 20 in, the pump st rt n os~t~o"~ n:
Not-02-98 04: 14P Nel less Translatioris, INC. P. 12 The ventilation aperture 20 joins a connecting channel 21 which passes through the housing 4 in vertical direction and which is connected with the interior 22 of the bottle 2. When the bridge sections a, b, buckle, as shown in Fig. 2, the locking part 19 on the bridge section b lifts oft from the ventilation aperture 20. The partial amount of the fluid substance 23 discharged from the bottle 2 in this position is thus supplemented with air.
As shown in Fig. 3, the hinge jointed bridge sections a, b are resting tightly on the level, horizontal upper side 24 of the housing 4 when the spray pump 3 is in staking position. When the discharge is activated, the bridge sections a, b move roof-like outward away from the upper side 24, proceded by the living hinge point which was created in the area of the hinge joint 15, however, without giving up the lateral support from the lateral walls 16 of the bridge section b provided by the guide support on the verllcal walls of the pump housing 4, or the respective support from the two root sections 17.
The free end of the second bridge section b opposite to the mouth piece opening 9 is provided with a downward directed U-profiled part 25. It also represents an extension of the U-shaped cross section design of the second bridge section b, so that the second bridge section b represents the connector of the U-profiled part which encompasses the housing 4 in a U-shape.
One locking peg 26 each Is provided on the insides of the U-sections of the U-profiled part 25.
The peg 26 engages in a counter locking contour 27. The respective locking connection between the U-profiled part 25 toward the housing 4 is illustrated particularly clearly in Fig. 3. The counter locking contour 27 is provided with an opening 28 which faces away from the mouth piece opening 9.
ov-UZ-98 U4: lEiP Nel less Trans lations, INC. P.O1 ~ .
The opening's 28 inside diameter is somewhat smaller than the cross section of the circular peg 2t3.
At the level of the second hinge point II the U-profiled part of the link chain is horizontally and longitudinally slit up to the U-connector, i.e, the U-sections. The longitudinal slit has reference No. 29 and provides a peripheral material bridge.
The second hinge point II repfe~ents a living hinge. The V-notch slopes outward and is clearly diverging. The hinge point II, which is located on the side of the housing 4 opposite to the mouth piece opening 9, is slightly above the place of the locking connection 26127.
Beginning at the actual cylindrical plunger section of the pump plunger 6 the latter continues tapering from an eccentric shoulder 30 approximately to the mouth piece opening 9. This is a type of plunger shaft 31 which adds a connecting channel 32 between the pump chamber 7 and the mouth piece opening 9. On the side of the mouth piece, the pump plunger 6 is connected with a mouth piece cap 33. It is a form-fit connection. The cap 33 is clipped on irreversibly, which is achieved by means of a pot-shaped ring collar 35 attached to the casing of the plunger shaft 31. The ring collar's 35 pot-shaped wall defines the tube-shaped front end 36 of the hollow plunger shaft 31 or of the pump plunger 6, respectively.
A discharge valve V1 in the form of a moldable rubber piece is housed iwa space between the front end 36 and the attached mouth piece cap 33.
Nov-OZ-98 04:17P Nelles Translations, INC. P.02 The rubber piece has a collar 37 which is plugged onto the tube-shaped front end 36 of the pump plunger 6. In addition, the rubber piece is provided with an integrally attached disk-shaped bass part 3$ containing axially oriented flow-through cross sections 39. These are connected with supply lines 40 leading to the mouth piece opening 9 in that the rotating mouth piece cap 33 on the ring collar 35 of the pump plunger 6 is rotated. The respective open and close positions are defined by a stop. The front edge of the mouth piece cap 33 keeps the pockets 13 on the side of the mouth piece opening closed.
The flow-through cross sections 39 and the supply lines 40 are eccentrical with respect to a horizontal rotational axis x-x of the pot-shaped mouth piece cap 33. The axis is identical to the longitudinal center axis of the pump plunger 6.
The locking valve V1 also acts as a tube valve in that the collar 37 expands with the pressure caused by the fluid.
The windows 41 in the wall of the tube-shaped front end 36 provide access for the media (n order to expand the collar 37. The medium rushes into a ring chamber 42 provided between the casing of said tube-shaped front end 36 and the interior wall of the ring collar 35.
The ring chamber 42 is closed on the plunger side by means of a transverse wall 43 on the plunger shaft 31.
Closer to the interior 22 of the bottle 2 is the inlet valve V2 which also consists of an elastic material and which is disk-shaped. It is equipped with a centrally located valve locking piece 44 which is supported by crosspieces 45 that leave a flow path between them.
CA 02300109 2000-02-14.
Nov-02-98 04:17P Nelles Translations, INC. P.03 The crosspieces 45 extend substantially radially. They preferably curve in the shape of an S to achieve the opening and closing flexibility for the valve locking piece 44.
The valve locking piece's 44 valve seat on the housing side is designated with 46.
The inlet valve V2 is supported by the bottom 47 of the pump chamber 7 opposite to the mouth piece opening 9 and is held in position by the pump plunger restoring spring 8 in that the winding at its end pushes the disk-shaped body of the inlet valve V2 againsl the bottom 47.
The opposite end of the pump plunger restoring spring a acts as a load against the cross section-reducing shoulder 30 in the interior of the hollow pump plunger 6.
As shown in Fig. 3, the end of the pump plunger 6 opposite to the shoulder 30 is rotation symmetrically formed into a ring lip. It forms an edge 48 while the cross section of the remaining cylinder wall of the pump plunger 6 recedes. The edge's 48 larger cross section opening trails on the wall of the pump chamber 7.
Following a short horizontal channel section, the valve seat 46 changes to a vertical channel section 49 which continues in a connection piece 50 where an ascending pipe 51 is clamped on.
The ascending pipe 51 nearly reaches the bottom of the bottle 2.
For a tight fit between the spray pump 3 and the bottle the housing 4 forms a ring wall 52 at its underside.
Nov-02-98 04:17P NQII~s Translations, INC. P.04 The ring wall 52 is pushed into the opening al the neck 1 to provide a tight seal.
In order to attach the spray pump 3 the housing 4 is plugged onto the neck 1 of the bottle 2 by means of a plug-in/clip connection. This is achieved with a plug-in collar 53 which is equipped with locking fingers 54 located on diametrically opposed sides. By means of an irreversible snap connection, the locking fingers 54 engage in a blocking flank 55 on the neck 1. This is provided at the underside of a collar-like projection and is overrun in forward motion by the locking fingers 54 acting like barbs.
The blocking flank 55 represents the upper end of a cavity 56 on the casing of the neck 1, The width of this cavity 56 in circumterential direction of the neck 1 corresponds to the width of the locking fingers 54 which also achieves an advantageous rotation lock. This results in a defined orientation for the hammer head-like spray pump 3 with respect to the bottle body which may be designed flat in the same direction.
Wlth respect to the supply lines 40, it should be noted that they end tangentially in a collecting chamber which creates a swirl chamber 57. This causes a rotation effect and thus generates a stable stream.
The discharge valve V1 is mounted non-rotating in the ring chamber by means of an eccentric projection 58 which projects into a matching recess (not shown) in the ring collar 35.
Nov-ul.-~ti u~a: W' Ne I les i ram nations, 1NC:. P.05 The variant of the spray pump 3 illustrated in Figs. 5 through 8 is designed according to the same principle. The reference Nos. are used accordingly. Any extensive applicable specifications are not repeated.
The modified ajr compensation system is discussed first. With respect to activation, it has been shifted to the range of action of the pump plunger 6. The latter represents a productive functional part of this system. The pump plunger 6 acts as a slide.
In actuality, this is embodied in that the housing wall 60 is equipped with a ventilation aperture 61 on a plane of projection on the bottle neck 1. The aperture 61 provides the shortest possible flow connect on between the pump chamber 7 and the interior 22 of the bottle 2. The ventilation aperture 61 extends on the underside of the housing 4 as defined by the ring wall 52. The latter is pushed into the opening on the bottle neck 1 to seal.
In pump starling position (also see Fig. 5), the ventilation aperture, the mouth 62, on the pump chamber side is closed by the casing of the pump plunger 7. As shown, said mouth 62 extends directly behind the edge 48 of the pump plunger 7 which edge acts as a piston ring 63.
A second piston ring, designated with 64, is provided axially spaced apart and offset in the direction of the mouth piece opening 9 of the spray pump 3. Both piston rings 83, 64 are pointed in the form of a lip in the direction of their free ends. With respect to the discharge direction, the piston ~ngs 63, 64 are receding and have a pitch of approx. 30° with reference to the axis x-x.

A spray pump of this type is specified in US-PS 4,955,511, where the hand lever is a trigger lever which is rigidly connected with the pump plunger. This causes a tendency for the pump plunger pump chamber unit to tilt.
US-PS 3,7213,442 specifies a hand lever-operated spray pump whose hand lover is arranged on a pivoting bearing by means of a fork recess / peg engagement on the housing side. Separated by a space thereto, it acts via a living hinge in conjunction with a transmitting part provided on the upper side acting upon the pump chamber, which Is a bellows-type pump in this case. The transmitting part is connected to the housing on the side opposite to the mouth piece by means of an additional living hinge. A finger on the transmitting piece closaslopens an air compensation opening.
It is the object of the invention to provide a hand levee operated spray pump of the shove type which is functionally r~elfable and structurally simple.
This problem is solved substantially with a hand lever operated spray pump having the characteristics of Balm 1, provided that two hinge points are allocated to the hand lever Nov-02-98 04:12P Nell~s Translations, INC. P.04 one of which is moving non-rotating on the housing side in a linear guide provided on the housing side, and the other is attached to the housing on the side opposite to the mouth piece in such a way that both hinge points are connected via~ero brjs(o_e ~ectionQ ~~at buckle with respect to each other. Thisprevents t,e lau_m_hnlunger from tilting. The hand lever performs an overriding movement: swiveling plus shifting. The respective linear guide is defined by the guide on the housing side. The resulting convergence of the two hinge points is compensated simply in that the bridge sections buckle or fold. This movement can even be utilized as a force for restoring th~"pumo I umler to its staAlng oosition by means of a hand lever couenng. The bridge sections' buckling movement may then be utilized for an additional function in that one bridge section supports the sealing part for a ventilation aperture which leaves its seating position with rospect to the ventilation aperture during the buckling process. This solves the problem of air compensation by the easiest possible method. As the buckling process takes place only when the pump is activated, this provides for a space-saving outline in non-operating position, offering both storsge and packaging advantages. According fo the subJect matter of US~PS 3,726,442, the overall size of the spray pump decreases only when it is adlvated. In addition, the invention pro sea to rovide a livin hin a point between the two brid a tlons, thereby eliminating the need for classic axes. The sewn r ge sec ion is then further developed such that it represents the connector on a U-profiled part that encompasses the housing in a U-shape. This provides a strong coupling for the bridge.
Nov-02-98 04:12P Nalles Translations, INC. P.05 In addition, the design is characterized by a locking connection from the U-profiled part toward the housing. In order to prevent that this locking point is required for the purpose of achieving the required flexibility for the respective bridge section, the hinge point, located on the side of the spray pump opposite to the mouth piece, is a living hinge adjacent to the place of the locking connection. This also prevents any movements caused by the bridge sections' movement to be transferred to said place. In addition, a proposal is made, which has its own significance, according to which the pump plunger continues tapering approximately up to the mouth piece where it is in form-fit connection with a mouth piece cap and that, between the two parts, s discharge valve is provided in the form of a moldable nrbber piece. This represents a structural simplification, allows easy assembly and requires fewer parts. The rubber piece is of the type which remains closed until a certain high pressure response threshold is reached at which time it opens abnrptly. This results in a powerful spray, especially if the rubber piece is mounted on the front end of the pump plunger and is equipped with a collar which expands as a rosult of the prossure caused by the Huid, and if it has axial flow-Ihrough cross sections in a disk-shaped part.
These cross sections are connected with the mouth piece opening in that the mouth piece cap is rotated. This should be based on eccentricity in order for the spray pump to be superior with respect to media losses as well. It is advantageous if the spray pump housing is attached to the bottleneck by means of a plug-inlclip connection substituting the normally used swivel nut. With the attachment of a collar, the plug-in connection is able to simultaneously function as a sealing connection.
Nov-02-98 04:12P Nallas Translations, INC. P.06 In addition, the spray pump as per the invention is characterized by a disk-shaped inlet valve having a valve locking piece which is supported by crosspieces. The pump plunger restoring spring is supported by said crosspieces. The opposite end of the spring moves against a cross section-decreasing shoulder in the interior of the hollow pump plunger which trails on the wall of the pump chamber with the edge of the larger cross section opening. This edge is preferably a sleeve-like lip. It is also advantageous to equip the pump plunger with lateral pockets for the hinge point on the hand lever side. The hand lever axle stubs passing through the linear guide are inserted in the pockets. An advantageous variant of an air compensation system is the utilization of the pump plunger. According to this variant, the hou ' y wall of the ump chamber ~nrnvided with a ventilation aEerture extendin4 into ~,h.~.jnt~fiQS.of the boUle~.St)Lhali~e pump is in its starti_ngr~.siti_Qn_~the apertu~e~ which_is.located directly_behind the edge of the"eump plunger, is closed h~e..pirt~p.ptungef~,and op~n;s. when. the pump pl~~g~~is activated. This provides for an additional pump plung~~er function. It acts as a slide. his doss not even require sin well is co ~uslyr leading. It s,gffices to equip the pump elun ~er ~with two pislon rings hich in t a ~m~c~plunoer startin~a position, are located on either side~e m ilation aperture. This decreases the friction against the pump plunger and favors the desire easy ac vation of the trigger pump. There is an added advantage in that, as a result of creating the ring space, the pump plunger, positioned in the direction of discharge, acts as a seal with relation to the pump chamber, for example in the event of excess pressure in the bottle which may be generated by heat.
Nov-UZ-9S U4: 1,31 N~ I les I tans lations, INC. P.07 An advantageous further dwelopmenl should be noted with respect to the inlet valve. This development is achieved by a disk-shaped inlet valve body which is symmetrical with relation to the disk center plane. The respective mirror symmetrical loan permits the use of either side of the inlet valve body, thereby preventing any assembly mistakes or re-work requiring that a side inverted inlet valve be reversed. Regardless of ils allocation, the desired valve function is always reliable. It is also advantageous for the valve locking body of the inlet valve to be barrehshaped having hemispherical ends on both sides. The valve locking body is located in the center of the disk-shaped inlet valve body. Furthemnore, the discharge valve is also further developed which is characterized in that the discharge valve is covered by the mouth piece cap and that il is equipped on the fore-part with supply channels leading toward the mouth piece opening. The supply channels can be closed by rotating the mouth piece cap. This is achieved in that the discharge valve is a moldable rubber piece which is equipped with a stem. One end of the slem supports a valve disk while the other end is equipped with a cylindrical stopper part having diametrically opposed flattened parts that ueate channels. Supply channels lead from the front of the flattened parts to a central swirl chamber. Due to its larger mass of material the stopper part is virtually not moldable so that the channel cross sections remain largely unaffected despite the pressure caused by the media, while the valve disk provides the flexibility and re:toting force required for the valve function.
Nov-02-98 04:13P NollQS Translations, INC. P.08 For the purpose of locking it is advantageous for the swirl chamber to be eccentrical, resulting in a congnrent position with the mouth piece opening, which is also eccentrical, and the ability to leave this position which results in blocking the discharge path. Finally, with rasped to the axis of the second bridge section, it is proposed to use a hook for the locking connection on the housing side for the second buckling bridge section. The hook is adjacent to a supporting crosspiece whose front surface forms the hinge point in that it is thrust against a housing console at the rear.
It is structurally advantageous for the hook to pass through a hole in the rear housing console, and that the supporting crosspiece, which is located behind the hole and which croates the hinge point and runs substantially parallel with the shaft of the hook, forms the end of the second buckling bridge section. The close proximity between the supporting crosspiece and the hook provides for sufficient play to allow the bridge sections to buckle. Added to that is the flexibility and restoring force of the material used, i.e. synthetic material.

A spray pump 3 is allocated to the neplc 1 of a bottle 2. It is a so-called trigger pump, representing a standing unit in the form of a dispenser for dispensing a powerful spray.
The core of the spray pump 3 is the housing 4, which extends in the manner of a hammer head transverse to the neck 1 which is substantially vertical. The neck 1 is grasped to provide counter support. A hand lever 5, projecting toward the underside of the housing 4, is located in the range of action of a respective holding hand.
The hand lever 5 swivels about a horizontal first hinge point I of the activation mechanism, i.e, it is pulled agaMst the neck 1. This takes place against a spring loading which, upon release, aMraya returns the hand lever 5 to the starting position as shown in Fig. 3.
Nov-02-98 04:14P NallQS Translations, INC. P.10 The activation position is shown in Fig. 3 with dash~dot lines.
The hand lever 5 is coupled to a pump plunger 6 which moves in a pump chamber T that forms a pump cylinder.
The connection between the hand lever 5 and the pump plunger 6 is such that the hand lever 5, in addition to the above mentioned swiveling movement, shifts linear in the pump chamber together with the pump plunger 6. The respective displacement acts against the expansive power of a pump plunger restoring spring t3 which is located in the pump space. This spring is a threaded pressure spring.
The overriding movement made by the hand lever 5 is realized via a linear guide on the housing side. Longitudinal slits 10 begin at the tube-shaped end of the housing 4.
This end faces the mouth piece opening 9 of the spray pump 3. The longitudinal slits 10 are open toward the front edge of the tube and extend diametrically in Longitudinal diroclion. Their horizontal depth defines the operating stroke in that the axle stubs 11 of the hand lever 5 which create the physical hinge point I move against the interior slit bottom 12.
The axle stubs 11 traverse the longitudinal slits 10, which are arranged in pairs, and at the end they engage in respective pockets 13 provided on the two longitudinal sides of the pump plunger 6. This results in driving the pump plunger 6 in the sense that the volume of the pump chamber 7 decreases.
Nov-02-98 04:14P N~IIQS Translations, INC. P.11 The hand lever 5 is connected with the housing 4 by means of a link chain. In actuality, this is achieved in that two hinge points are allocated to the hand lever 5, the abovo montioned hinge point I and a second hinge point, designated with II, which is located on the side of the pump housing 4 opposite to the mouth piece opening 9.
The two hinge points I, II are connected by means of twe bridge sections a b that buckle with relation to each~er. The buckling position is seen in Figs. 2 and 3. In order to permit the bridge ~._ sec ns a, b to buckle respectively opposite to the housing 4, they are connected vita hinds ~omt 15 hrch may be a living hinge. The respective V-notch 15' continues into the cheek-like -~~[~~,~~ 16 of the cap-like bridge section b and also into the shield-like root section ~Torthe hand lever 5. The coaxially oriented axle stubs 11 are attached to the insides of the root section 17.
Consequently, the bridge section b which changes to the substantially vertical side walls 16 is U-shaped.
In contrast, the root section 17, which is attached to the bridge section a and represents a part thereof, is closed toward the grip section of the hand lever 5 allowing the tube-shaped end of the housing 4 to pass freely. This provides a plug-in hole 18 for the purpose of assembly.
The bridge section designated with b supports a locking part 19 which tightly seals a congruently positioned ventilation a~etiure 20 in, the pump st rt n os~t~o"~ n:
Not-02-98 04: 14P Nel less Translatioris, INC. P. 12 The ventilation aperture 20 joins a connecting channel 21 which passes through the housing 4 in vertical direction and which is connected with the interior 22 of the bottle 2. When the bridge sections a, b, buckle, as shown in Fig. 2, the locking part 19 on the bridge section b lifts oft from the ventilation aperture 20. The partial amount of the fluid substance 23 discharged from the bottle 2 in this position is thus supplemented with air.
As shown in Fig. 3, the hinge jointed bridge sections a, b are resting tightly on the level, horizontal upper side 24 of the housing 4 when the spray pump 3 is in staking position. When the discharge is activated, the bridge sections a, b move roof-like outward away from the upper side 24, proceded by the living hinge point which was created in the area of the hinge joint 15, however, without giving up the lateral support from the lateral walls 16 of the bridge section b provided by the guide support on the verllcal walls of the pump housing 4, or the respective support from the two root sections 17.
The free end of the second bridge section b opposite to the mouth piece opening 9 is provided with a downward directed U-profiled part 25. It also represents an extension of the U-shaped cross section design of the second bridge section b, so that the second bridge section b represents the connector of the U-profiled part which encompasses the housing 4 in a U-shape.
One locking peg 26 each Is provided on the insides of the U-sections of the U-profiled part 25.
The peg 26 engages in a counter locking contour 27. The respective locking connection between the U-profiled part 25 toward the housing 4 is illustrated particularly clearly in Fig. 3. The counter locking contour 27 is provided with an opening 28 which faces away from the mouth piece opening 9.
ov-UZ-98 U4: lEiP Nel less Trans lations, INC. P.O1 ~ .
The opening's 28 inside diameter is somewhat smaller than the cross section of the circular peg 2t3.
At the level of the second hinge point II the U-profiled part of the link chain is horizontally and longitudinally slit up to the U-connector, i.e, the U-sections. The longitudinal slit has reference No. 29 and provides a peripheral material bridge.
The second hinge point II repfe~ents a living hinge. The V-notch slopes outward and is clearly diverging. The hinge point II, which is located on the side of the housing 4 opposite to the mouth piece opening 9, is slightly above the place of the locking connection 26127.
Beginning at the actual cylindrical plunger section of the pump plunger 6 the latter continues tapering from an eccentric shoulder 30 approximately to the mouth piece opening 9. This is a type of plunger shaft 31 which adds a connecting channel 32 between the pump chamber 7 and the mouth piece opening 9. On the side of the mouth piece, the pump plunger 6 is connected with a mouth piece cap 33. It is a form-fit connection. The cap 33 is clipped on irreversibly, which is achieved by means of a pot-shaped ring collar 35 attached to the casing of the plunger shaft 31. The ring collar's 35 pot-shaped wall defines the tube-shaped front end 36 of the hollow plunger shaft 31 or of the pump plunger 6, respectively.
A discharge valve V1 in the form of a moldable rubber piece is housed iwa space between the front end 36 and the attached mouth piece cap 33.
Nov-OZ-98 04:17P Nelles Translations, INC. P.02 The rubber piece has a collar 37 which is plugged onto the tube-shaped front end 36 of the pump plunger 6. In addition, the rubber piece is provided with an integrally attached disk-shaped bass part 3$ containing axially oriented flow-through cross sections 39. These are connected with supply lines 40 leading to the mouth piece opening 9 in that the rotating mouth piece cap 33 on the ring collar 35 of the pump plunger 6 is rotated. The respective open and close positions are defined by a stop. The front edge of the mouth piece cap 33 keeps the pockets 13 on the side of the mouth piece opening closed.
The flow-through cross sections 39 and the supply lines 40 are eccentrical with respect to a horizontal rotational axis x-x of the pot-shaped mouth piece cap 33. The axis is identical to the longitudinal center axis of the pump plunger 6.
The locking valve V1 also acts as a tube valve in that the collar 37 expands with the pressure caused by the fluid.
The windows 41 in the wall of the tube-shaped front end 36 provide access for the media (n order to expand the collar 37. The medium rushes into a ring chamber 42 provided between the casing of said tube-shaped front end 36 and the interior wall of the ring collar 35.
The ring chamber 42 is closed on the plunger side by means of a transverse wall 43 on the plunger shaft 31.
Closer to the interior 22 of the bottle 2 is the inlet valve V2 which also consists of an elastic material and which is disk-shaped. It is equipped with a centrally located valve locking piece 44 which is supported by crosspieces 45 that leave a flow path between them.
CA 02300109 2000-02-14.
Nov-02-98 04:17P Nelles Translations, INC. P.03 The crosspieces 45 extend substantially radially. They preferably curve in the shape of an S to achieve the opening and closing flexibility for the valve locking piece 44.
The valve locking piece's 44 valve seat on the housing side is designated with 46.
The inlet valve V2 is supported by the bottom 47 of the pump chamber 7 opposite to the mouth piece opening 9 and is held in position by the pump plunger restoring spring 8 in that the winding at its end pushes the disk-shaped body of the inlet valve V2 againsl the bottom 47.
The opposite end of the pump plunger restoring spring a acts as a load against the cross section-reducing shoulder 30 in the interior of the hollow pump plunger 6.
As shown in Fig. 3, the end of the pump plunger 6 opposite to the shoulder 30 is rotation symmetrically formed into a ring lip. It forms an edge 48 while the cross section of the remaining cylinder wall of the pump plunger 6 recedes. The edge's 48 larger cross section opening trails on the wall of the pump chamber 7.
Following a short horizontal channel section, the valve seat 46 changes to a vertical channel section 49 which continues in a connection piece 50 where an ascending pipe 51 is clamped on.
The ascending pipe 51 nearly reaches the bottom of the bottle 2.
For a tight fit between the spray pump 3 and the bottle the housing 4 forms a ring wall 52 at its underside.
Nov-02-98 04:17P NQII~s Translations, INC. P.04 The ring wall 52 is pushed into the opening al the neck 1 to provide a tight seal.
In order to attach the spray pump 3 the housing 4 is plugged onto the neck 1 of the bottle 2 by means of a plug-in/clip connection. This is achieved with a plug-in collar 53 which is equipped with locking fingers 54 located on diametrically opposed sides. By means of an irreversible snap connection, the locking fingers 54 engage in a blocking flank 55 on the neck 1. This is provided at the underside of a collar-like projection and is overrun in forward motion by the locking fingers 54 acting like barbs.
The blocking flank 55 represents the upper end of a cavity 56 on the casing of the neck 1, The width of this cavity 56 in circumterential direction of the neck 1 corresponds to the width of the locking fingers 54 which also achieves an advantageous rotation lock. This results in a defined orientation for the hammer head-like spray pump 3 with respect to the bottle body which may be designed flat in the same direction.
Wlth respect to the supply lines 40, it should be noted that they end tangentially in a collecting chamber which creates a swirl chamber 57. This causes a rotation effect and thus generates a stable stream.
The discharge valve V1 is mounted non-rotating in the ring chamber by means of an eccentric projection 58 which projects into a matching recess (not shown) in the ring collar 35.
Nov-ul.-~ti u~a: W' Ne I les i ram nations, 1NC:. P.05 The variant of the spray pump 3 illustrated in Figs. 5 through 8 is designed according to the same principle. The reference Nos. are used accordingly. Any extensive applicable specifications are not repeated.
The modified ajr compensation system is discussed first. With respect to activation, it has been shifted to the range of action of the pump plunger 6. The latter represents a productive functional part of this system. The pump plunger 6 acts as a slide.
In actuality, this is embodied in that the housing wall 60 is equipped with a ventilation aperture 61 on a plane of projection on the bottle neck 1. The aperture 61 provides the shortest possible flow connect on between the pump chamber 7 and the interior 22 of the bottle 2. The ventilation aperture 61 extends on the underside of the housing 4 as defined by the ring wall 52. The latter is pushed into the opening on the bottle neck 1 to seal.
In pump starling position (also see Fig. 5), the ventilation aperture, the mouth 62, on the pump chamber side is closed by the casing of the pump plunger 7. As shown, said mouth 62 extends directly behind the edge 48 of the pump plunger 7 which edge acts as a piston ring 63.
A second piston ring, designated with 64, is provided axially spaced apart and offset in the direction of the mouth piece opening 9 of the spray pump 3. Both piston rings 83, 64 are pointed in the form of a lip in the direction of their free ends. With respect to the discharge direction, the piston ~ngs 63, 64 are receding and have a pitch of approx. 30° with reference to the axis x-x.

Any excesapressure.whichmaybe causedby heat, is transferred to the ring chsmber65. This causesthe side of the secondpiston ring 64 on the ring spaceside to be pressedeven moretightlyagainstthe cylinderwall of the pump chamber 7, therebyincreasinøhe sealingeffect. If the bottleshouldfall, no fluid is ableto flow out.

Accordingto the spraypump 3 variant,the inletvalve V2 is designedn such a wsy that, regar0lasaof whichof its surfacesmeetsthe bottom47 of the pumpchambar7. it is slwaysproperlyplaced.This is dueto the mirrorsym~netricaldesign.Again.it is basedon a disk-shapednletvalvabodymadeof a readjustablematerlalwith a centrallylocated valvelockingpiece44. However,the centrallyiocatedlockingpiece44, whichegsinis attachedto crosspieces45, is now designedend identical,i.e. s barrel-shapedocking piece is equippedaxiallyon both sides or both ends, respectively~vith convex hemisphericabnds.
Nov-02-98 05:~8P Nollas Translations, INC. P.03 The end on the allocationside acts togetherwith the valve seat 46 on the bottom47. The centeraxis of the barrel-shapadockingpiece4 [sic) coincideswith the rotationabxis x-x of the pot-shapedmouthpiececap 33. In addition,this axis is identicsho the longitudinal centersxis of the pump plunger8.

With respectto furtherdevelopinghe disChargevalve V 1, the pot-sh~eddesignhas been modifiedto a solid body. Referenceis made to Figs. 5 and 7.
Again.ths dischargevsivs V 1 is allocetedto the mouthpiececep 33 in such a way that the supplychannst:86, locatedon the fore-partof the dischargevalve V 1, can be closed with relstionto the decentrallylocatedmouthpisceopening9.

The tangentinflow is also diametricallyopposed.The supplychannels66 appearingn the form of troughson the front surfacein Fig. 7 are covere~y the interiorsurfaceof the bottomof the mouthpiece cap 33.
The swirl chamber74 is eccentricwith respectto the rotationalsxis x-x of the mouth piececap 33. The sameappliesto the mouthpieceopening9 whichfomns the spray nozzleof the spraypump 3.
