INVENTOR ATTORNEY RICHARD C. SPEAK DEVICE FOR DISPENSING LIQUID OR PASTE MATERIAL BACKGROUND OF THE INVENTION AND FIELD OF THE INVENTION This patent application is a continuation-in-part application of patent application Ser. No. 166,406, filed July 27, 1971, now abandoned.

The present invention relates to that class of devices useful in dispensing small uniform quantities of a liquid or paste cleaning material. In workshops, laboratories, repair shops and similar working zones clean-up areas have been set aside. Such clean-up rooms are frequented by many individuals who require access, for instance, to cleansing material. Providing soap and de tergent bars for multiple use poses many problems as many individuals dislike employing a soap bar which had been used only a short time before by someone else, who may leave a wet soggy soap bar. To obviate this problem to a degree, powdered soap dispensers have been provided. These powdered soap dispensers are not usually useful in dispensing a paste material, as the powdered soap dispensers usually depend upon gravity flow for successful operation. Unless there is provision for positive pumping action the paste, if very viscous will be dispensed at an extremely slow rate, if at all.

Cleansing paste has certain advantages over the powdered soap. For instance, powdered soap may cake in the hands and may require vigorous rubbing with water before it becomes solubilized and loses its grittiness. On the other hand, cleansing paste is usually already partially emulsified in a diluent resulting in quick further dispersal. Instead of dispensing cleansing paste, it is oftentimes desirable to provide for small quantities of a lotion material which is applied to the hands as a tection and barrier to dirt.

It will be seen, therefore, from the following that the field of the invention pertains to means useful in dispensing small increments of a liquid or preferably a paste directly in the hand or hands of an individual from a reservoir.

PRIOR PRACTICE SUMMARY OF THE INVENTION The present invention contemplates a device having a reservoir for paste or liquid material wherein the reservoir is in fact the container in which the paste or material is stored and sold. The device retains the container in a vertical position. An orifice in the container is in alignment with the receiving end of a horizontally disposed Moyno pump, such was first disclosed in US. Pat. No. 1,892,217. The pump carries discrete increments of the paste or liquid to near the forward portion of the device at which point it is permitted to be discharged. A forwardly extending knob is provided to opembodiment.

erate the pump. Various modes are contemplated; for

instance, the knob may be merely an extension of the rotor of the pump so that as the knob is rotated the pump will operate. On the other hand, more importantly, the knob may operate a slip-clutch so that the pump is operated only when the knob is rotated in one direction. The slip-clutch may be one of a variety such as a conventional ratchet arrangement. A contemplated form is the use of a pad of rigidly fixed short strands on one surface wherein the strands are set at approximately the same acute angle with respect to the surface. The confronting opposite surface takes the form of a wire screen (may be of metal or synthetic resin). The strands are permitted to enter the interstices of the screen. The resultant is a slip-clutch as the strands are coupled to the screen when one of the surfaces is rotated in one direction and uncoupled when rotated opposite thereto.

The manually operated knob may be coupled to a suitable camming device whereby the knob reciprocates and such action produces rotary motion.-

DESCRIPTION OF THE PREFERRED EMBODIMENT Turning to FIGS. 1 and 2 for an initial description of the invention, reference numeral 11 refers to the device of the present invention. It will be seen that the device 11 presents an attractive appearance. The cylindrical object shown by the dotted lines refers to the reservoir 12 for containing a paste, for instance, for dispensing. The reservoir in this embodiment is a can which is opened in its center, then inverted and positioned upside down as seen in FIG. I.

The device possesses upstanding annular wall 13, which has an internal diameter slightly larger than the external diameter of the reservoir 12. The annular wall 13 is lower in the front and increases in height towards the back. The annular wall 13 has a flat appendage l4 integral therewith, for instance, so that the device may be attached to a suitable bracket (not shown) and may then be mounted on a wall. It is partially for this reason that the annular wall 13 is higher at the back. Another reason is to provide for easier insertion of the reservoir from the front into the position, as shown.

The device has a floor 15 on which the reservoir 12 rests. As seen more clearly from FIG. 2, and especially, FIG. 3, the floor 15 has an annular concentric groove 16. Conventionally, the cam has a protruding crimped edge where the top of a can and the side cylinder portion of the can mate. The groove 16 is designed to accept the crimped end of the can.

The floor 15 has an opening 17 into which the contents of the reservoir are to flow. The opening 17 has a channel 8 in operative association therewith in order to bring the contents of the reservoir to a pumping mechanism located in the body of the device. The opening 17 is shown in the drawings to have a rectangular configuration. This may be changed to either square, round or polygonal.

The forward portion of the device 11 has a knob 18 which is hand manipulated when it is desired to dispense a quantity of the paste from the reservoir 12. A number of operating means are contemplated within the purview of the invention. For instance, the knob 18 may be pushed inwardly or it may be turned in either direction. In one embodiment, the knob 18 is pushed inwardly. By suitable operative means located internally with respect to the device, the knob 18 is urged normally outwardly by resilient means, such as a spring.

For further elucidation with regard to this embodiment, attention is directed to FIGS. 3 and 4. FIG. 3 being a cross section of the device 11 depicts a pump, generally 21, and a transmission means, generally 22. The pump is of the type first disclosed in U.S. Pat. No. 1,892,217 and subsequently improved in U.S. Pat. Nos. 3,203,350 and 3,280,753. The pump 21 comprises a horizontally longitudinal cylinder 23 in or part of the device 11. The cylinder 23 is in communication at one end with the terminus of channel 8. The paste is fed into a space 24 in the cylinder 23. The cylinder 23 has concentrically positioned therein an elastomeric stator 25 having a centrally located bore 26. The walls of the bore are helically grooved as at 27. An elongated metal or rigid synthetic resin helically shaped rotor 28 is positioned within said bore 26. The maximum diameter of the rotor 28 is substantially identical to the maximum internal diameter presented by the bore 26. The stator 25 has one more helix than the rotor 28, thereby the rotor and stator cooperate to produce a series of pumping pockets which travel from end to end through the pump when the rotor is rotated. The configuration of the cooperating threads enforce upon the axis of the rotor an orbital path in a circle.

The transmission means includes in this embodiment a slip-clutch 29. For a clearer understanding of the transmission means attention is specially directed to FIG. 4. This figure shows in an exploded manner the transmission means. A bushing 30 is secured to an extending axle portion 31 of the rotor 28 and is secured thereto by set screw 32, for instance. Bushing 30 has an annular flange 33 extending radially with respect to the bushing 30. One side of the slip-clutch is secured to the surface 34 of the flange. This side 35 is an annular element having a plurality of short strands extending from the surface 34 at an acute angle with respect thereto and substantially all in the same direction and angle. The strands are relatively short and give the appearance of a brush with extremely short bristles. The strands may be constructed out of a number of materials, but synthetic resin monofilaments are preferred which may be subjected to what is conventionally known as a heat set in order to present and retain the face mentioned in the above.

The other side 36 of the slip-clutch arrangement is also an annular element of wire screen or mesh, very similar in size as conventional window screening. This screen is secured to the underside of an element 37 having a cup-like configuration. The said underside has a centrally located bore of a diameter to pass over bushing 30 when the transmission is assembled as in FIG. 3. The cup 37 has a cam slot 38 on the outersurface thereof.

Enclosing the entire transmission is the knob 18 mentioned in the above which takes the form of a large cup. The knob 18 has a radially inwardly extending stub 39 which is adapted to ride in the slot 38 when the transmission is assembled. A helical spring 40 is positioned between the inside bottom of the knob 18 and the inside bottom of the cup 37. The knob has at its open end portion an annular flange 41. A slot 42 is located from the said flange 41 along the cylindrical wall of the knob. When assembled a relatively large set screw 43 in slot 42 retains the knob 18 in the position shown in FIG. 3 which is themaximum at rest position. The set screw 43 also acts to limit the movement of knob 18 when it is moved in a direction towards the rear of the device 11.

In operation the knob 18 is pushed rearwardly which action will rotate the cup 37 counterclockwise due to the stub 39 riding in slot 38. Of course, this arcuate movement will rotate the screen 36. The helical spring compresses the screen and the side 35, the portions of the ends of the strands will enter the interstices of the screen and be driven when the screen is rotated. It is, of course, possible to reverse the position of the screen and the strand carrying annular element.

It will be seen that the transmission system will rotate rotor 38 in an arcuate increment every time the knob 18 is depressed. When knob 18 is released, spring 40 will return the knob to its normal outwardly extended position. Of course cup 37 will rotate carrying with it screen 36 which will turn in a clockwise direction passing over the edges of the strands without resistance as found when the screen is rotated in the first or counterclockwise direction.

When rotor 28 rotates it will pump a relatively small quantity of the paste from the space 24 to space 44 which coincides with downwardly depending opening 45. As noted in the above the rotation of the rotor produces a traveling cavity in which is contained a discrete quantity of paste. If no paste is dispensed with the initial depression of knob 18, it can be repeated for any desired number until dispensing action ensues. The pump utilized is of the positive displacement type so that a vacuum can be drawn in space 24 which is then filled with paste from the reservoir.

In a simpler construction, attention is directed to another embodiment as depicted in FIG. 5. Instead of employing the reciprocating knob 18, it is possible to employ knob 50 which is designed to rotate and to thereby rotate rotor 28 through a slip-clutch transmission means.

In this embodiment the knob 50 is journalled to axle 31 of the rotor by means of stub 51 which rides in annular groove 52. The underside face 53 of the knob 50 has an annular screen 54 secured thereto. The flange 33 on surface 34 has the strand arrangement secured thereto, as before. There is now in this embodiment a direct operative connection for rotating the rotor in one direction. In this embodiment one does not have the advantage of operating the device by, say, pushing with the elbow when ones hands are dirty. To rotate the knob 50 it is necessary to grasp the knob with a hand to make it rotate.

FIG. 6 depicts yet another embodiment in a transmission system. In this embodiment a knob 60 is keyed, as at 61, directly to the axle 31 of rotor 28. In this manner the knob 60 may be rotated while at the same time rotating the rotor 28 of the pump. This arrangement while operable has the disadvantage that when the knob 60 is rotated in the wrong direction, the pump being of the positive displacement type will pump air into the reservoir. Suitable indicia on the knob providing instructions should eliminate operating the pump in the wrong direction.

Now, turning to FIG. 8, it is contemplated that the fixed fiber surface be a sleeve 51 secured to thebushing 30. The screen is a cylinder 52 which is mounted to surround the sleeve 51. In this embodiment the cup 37 has an inner collar 53 to which is attached the cylinder 52. In use the drive is accomplished from cylinder to sleeve.

From the foregoing it will be seen that the reservoir is a can and the upper reaches of the device of the present invention have been adapted to accept a can. Attention is now directed to FIG. 7. In some instances, the material to be dispensed is contained in a glass or plastic bottle. This may be the situation when the material is less viscous than paste. In the embodiment of the present invention shown in FIG. 7, the upper portion of the device is modified to accommodate an inverted bottle. The device 11 now possesses upwardly extending cylindrical wall 65. Internally of said wall 65 is an inverted funnel arrangement 66 integral with said wall 65. The funnel arrangement 66 is designed to accept an inverted bottle 67, shown in dotted lines. The contents thereof are spilled into the channel 18 of the device as heretofore.

Turning now to FIGS. 9 to 14, it will be seen that the external appearance of the preferred embodiment as shown by these figures is essentially the same as in the other embodiments discussed heretofore. As especially shown in FIG. 9 the device has a forwardly downwardly sloping annular wall 13 and a bracket fastening means 14. A container 12A is inserted into the device.

A modification of the container is contemplated as can be more especially seen in FIG. by dotted lines. The reservoir which may be a container 12A has a centrally disposed neck which has a stopper 70 therein prior to insertion in the device. The device of the preferred embodiment has positioned in the orifice 71 upstanding spaced double elements 72 that extend a short way into orifice 71. The orifice is arranged arid constucted to accept the neck 12B of the container. In the preferred embodiment the stopper 70 is not removed from the container prior to inversion of the container into the dispensing device. The container is inverted and put into position. By pushing on the container so that the neck thereof moves into orifice 71 the upstanding elements 72 at their uppermost leading edges will push against the stopper which will become dislodged from the neck but will enter the main part of the container. By making the stopper of a material lighter than the material therein, the stopper will rise upwardly through the material.

As before the orifice 71 has a channel 8 in operative association therewith in order to bring the contents of the container, which as heretofore noted acts as a reservoir, to a pumping mechanism located in the body of the device.

The pump is essentially identical to that previously discussed, being a Moyno pump 21. As can be seen, FIG. 10 comprises a horizontally longitudinal cylinder 23 in or part of the device 11A. The cylinder 23 is in communication at one end with the terminus of channel 8. The paste is fed into a space 24 in the cylinder 23. The cylinder 23 has concentrically positioned therein an elastomeric stator 25 having a centrally located bore 26. The walls of the bore are helically grooved as at 27. An elongated metal or rigid synthetic resin helically sinuously shaped rotor 28 is positioned within the bore 26. The maximum diameter of the rotor 28 is substantially identical to the maximum internal diameter presented by the bore 26. The stator 25 has one more helix than the rotor 28, thereby the rotor and stator cooperate to produce a series of pumping pockets which travel from end to end through the pump when the rotor is rotated.

The transmission means includes in this preferred embodiment a slip-clutch 75. For a detailed understanding of the transmission means attention is especially directed to FIGS. 10 and 14. FIG. 14 shows in an exploded manner the preferred transmission means. A bushing 76 is secured to an extending axle portion 77 of the rotor 28. Bushing 76 has an annular flange 78 extending radially with respect to the bushing 76. A resilient washer 79 fits over the bushing 76. The extending axle 77 of the stator 28 is fitted into cup 80 which has an annular extension 80A at bottom thereof with a bore 80B. The axle 77 and bushing 76 projects through bore 805. An annular rigid element 83 is mounted over the axle. The surface thereof is in confrontation with the forwardly facing surface of the annular extension 80A. A helical coil spring 84 is next mounted over the extending axle'77. One end of the spring is in abutment with a surface of element 83. The other end fits into clutch cup 85.

The clutch cup 85, as can be more readily seen from FIG. 10, has a convoluted configuration. It has an outer cylindrical wall 85 which has been cut into radially extending leaves 86, each having abutment means 87. The clutch cup 85 has an annular bottom 85A against which internally thereof the other end of the helical spring 84 abuts. The clutch cup has an internal concentric cylindrical wall 858 projecting inwardly, the outer surface of which acts as a bushing for the helical spring 84. The cylindrical wall85B terminates at one end with the inner edge of annular bottom 85A and at the other with a bottom 85C having an opening therein to accommodate the extending axle 77. The bottom 85C extends with a concentrically position projection 88 with a bore 88A adapted to encompass non-rotatably the extending axle 77.

Surrounding all of the elements between the cup 80 and those discussed thereafter is a knurled cup 89 which possesses a plurality of spaced longitudinal pro- 7. jections 90 externally thereof to provide a good grip for the fingers when it is manually rotated. The knurled cup 89 has an annular bottom 92 which has opening 92A therein. An inwardly extending cylindrical member 97 is attached to the inner edge of the annular bottom 92 as seen also in regard to FIG. 10. The cylindrical member 97 has a shoulder 98 and a cylindrical longitudinal portion 99 extending therefrom. This portion 99 occupies the space between cylindrical wall 858 and projection 88.

A washer 93 is positioned over the end portion the axle 77. Finally, the assemblage is retained by a conventional lock ring 94 having radially inwardly extending leaves adapted to bite into the axle 77 to retard its removal therefrom. After assembly of the parts as just described, the opening 92A is closed by means of a disc 95 which also has embossed thereon arrows 96 to indicate direction,

When the assembly has been accomplished, it is mated with the device by inserting the rotor 28 into the bore 26 of cylinder 23. As can be seen, cup 80 has two cam slots 81 and 82 oppositely disposed. The upper slot 81 is aligned with upwardly extending stub 100 and at the same time the lower slot 82 is aligned with downwardly depending nozzle 101. The entire assembly, that is, pump and transmission system, are then rotated clockwise so that the stub 100 and nozzle 101 ride into their respective slots. Set screws 102 mounted in the floor of the device are used to prevent counter rotation of the assembly and release from its fixed position.

To operate the device the knurled cup 89 is rotated in a clockwise manner. In doing so at least one of the longitudinal inner projections 91 come in contact with the abutment means 87 of one of the leaves 86. The dimensional characteristics are such that the outwardly extending edge of each of the leaves slides along .the inner cylindrical wall of the knurled cup 89 until it comes in contact with one of the projections 91 at which point the knurled cup 89 is operatively connected to the clutch cup 85. Any further rotation in the same direction of the knurled cup will also rotate the rotor 28 as the axle 77 is non-rotatably coupled to the clutch cup 85.

The rotation of the rotor will carry the to-bedispensed paste from space 24 in the direction of nozzle I01. Nozzle 101 is normally closed by virtue of ball check valve 102.

To prevent operation of the pump in the opposite direction, thereby admitting air into the system, the projections 91 of knurled cup 89 will be seen to be a wedge-like configuration. When the knurled cup 89 is rotated in the other or counter-clockwise direction, the projections 91 depress the leaves 86 and the abutments 87 slide over the projections, thereby no rotation of the rotor is afforded.

The check valve is effective in shearing off the stream whenever the pressure is less than necessary to overcome its resistance. This prevents the possibility of a constant dribbling of the paste even though the pump has been stopped but there is a small amount of pressure present.

The spring 84 is useful in maintaining the cup 80 under pressure against washer 79, to prevent leakage between the surface of the washer and the forwardly extending edge of the cylinder. With effective selfeffectuating seals, it may not be necessary to include the helical spring 84.

The nozzle with an internal bore may have any acceptable configuration, provided that internally with respect thereto a seat is provided for the ball of the check valve and a shoulder in the bore for abutment of a helical spring wherein the other end is in abutment with the ball at the side opposite to its seat.

The device of the present invention may be constructed of metal or molded plastic or a combination of both materials.
