Description
~L185~
Dispenser for Pasty Substances The invention relates to a dispenser for pasty substances wi-th a housing having a piston displaceable only in a discharge direction and an outer operating handle which is fo~med at a headpiece, compressible in a bellows-like manner :Ln the clirection of the piston, the headpiece having a dispenser-o~tlet openiny at the outer end of a tubule, the inner end section o e which is immersed in the pasty substance on -the entire length projecting inwardly beyond the bellows~like headpiece.
.
Besides slide valves, it is known to use lip-like or ball valves (German AS 1,210,149). There, the piston is drawn by the vacuum which forms in the housing with each restoring action of the headpiece bellows, over the rilling column in the direction of the headpiece. In order not to lose this function by entry of air leakage via the dispenser-outlet opening, a valve is mounted in the latter which momentarily closes the opening again upon the dropping oE overpressure (pressure above atmospheric pressure).
The coordination of a corresponding dispensing valve is too expensive for a mass produced arkicle as, for example, a toothpaste-dispenser package. Moreover, operating breakdowns are to be expected since the headpiece bellows, which i5 formed from correspondingly softened material and thus considerably variable in shape, does not exclude shifting of the spring. Since, ultimately, the outlet valve is suddenly opened by a predetermined overpressure threshold, undesirable spray effects and, in any event, inexactly proportionable discharging amounts can result. Finally, there is also the disadvantage of a considerable expenditure for assembling and components. The spring closing the lips must be inserted from the inside. Since they are located in the region of the considerable deformable bellows the spring can lose its hold.

It is the objec-t of the inventlon to crea~e a dispen~er o this type, with a structure which is techni.cally simpl~r ~o manufacture and more advantayeous to use, in such a way that the noted discharge valve can be eliminated.
This object is solved by a tubule, immersed, with an inner always open mouth end being completely free, in every posi-tion of the bellows, in the pasty subs-tance, extending inw~rdly Erom -the dispenser-outlet opening.
As a result of such a design a dispenser of thls type is created which is satisfactory without any separate valve, however, still allowing an exactly proportionable, convenient to operate dispensing. The valve function, still attainable surprisingly with use of the inertia of the pasty substance, is also more advantageous in that an overpressure (pressure above atmospheric) for opening the valve, no longer has to first be produced, which overpressure always causes a more or less sudden, inadequately controllable discharging of the contents. In a structurally simple manner with the present invention, a tubule extends from the clispenser-outlet opening which tubule remains immersed in the pasty substance with its inner open mouth end in every position of the bellows with the inner always open, mouth end of the tubule being completely exposed communicating with the pasty substance in the housing. The factors such as -tubule cross-section, length and viscosity of the pasty substance are adjusted or balanced in such a way that the retraction of the piston occurs first, that is, before the pasty substance remaining in the tubule, which as a plug obstructs the tubule from communication with the outside air, can equalize the resulting vacuum with ai-r. The structural design of the dispenser i5 also considerably simplified. Such a tubule can be attached directly to or formed in one-piece on the headpiece. A

The structural design of the dispenser i5 also considerably simplified. Such a tubule can be attached directly to or formed in one-piece on the headpiece. A
separate construction is, however, recommended when substances of
- 2 -5~73~;
differiny viscosity and other charac~.e.r:i.st:Lc-i are .inv~lved, so tha.t by keeping the basic structure, comprisinCJ the housiny, clamp-locked piston and headpiece, it is then equipped, as required, with the cross-sectionally adapted tubule. A
formation, practically itself bringing about the operationally correct usage, exists when the tubule extends inclined at an acute-angle relative to the longi.tudinal axis of the tubular housing. This, above all, brings a desired, exact alignment of the tubule with respect to the discharge posi.tion as, for example, for the bristles part of a toothbrush. ~hereby, the inner open end of-the correspondingly coordinated tubule extends into the area of the longitudinal center axis of the housing, that is, into a central area which is convenient or favorable for pressing. If, finally, the bellows and its folding zone are formed in such a way that the tubule tilts, during bellows operation, in an approximately coaxial position relative to the longi.tudinal center axis of the housing, then the considerable operational advantage results that the dispensing-sided tubule end practically retracts from the projecting paste-extrusion.
~his facilitates the applicatio~ of this paste extrusion, which can also be.exactly followed visually, onto the toothbrush.
With the above and other ob,ects and advantages in view, the present invention will become more clearly understood in connection with the detailed description of a preferred embodiment, when considered with the accompanying drawings, of which:
Fig~ 1 shows a dispenser formed in accordance with the invention, in side view;
Fig. 2 is a base view thereof; and -~.3:~
~3S9311~
Fig. 3 is a longitu(llnal sec~ion throuyh the dispen~er wi-th closure cap indicated in d~sh-dotted lines.
The long cylindrical housing l contains a piston 2. Its peripheral edge lips ~' run alony the cylindrical inner side of housing wall l'. The housiny l is open at the bot-tom.
The piston 2 is only displaceable in the c1ischarginy direction (arrow x). On its wide surface, facing the assembly-~ided open end of the housing, it carries a so~cal].ed clamp module 3 in the shape of a star, made of spring steel, having substan~ially radially directed prongs 3'. Its diameter circumscribing khe prongs in the free non-inserted position is larger than the open diameter of the housing, whereby the prong ends blockingly hook-in as inclined support feet on the inner housing wall opposite to the direction of the arrow x preventing the piston 2 from moving down.
The dispensing-side closure of the housing l -forms an operating or actuation handle mounted opposite the standing base 4 of the same. It is a headpiece 5, compressible in a bellows-like manner in the direction of the piston 2, always returning spontaneously straightening again into its initial position~ The headpiece 5 is attached to the slightly narrowed neck 6 of the housing l~ By means of a ring-groove connection in cooperation wi-th the restoring force of the material forming the headpiece 5, there i5 provided a usable durable fastening.
The headpiece 5 forms a cross~sectionally narrowed dispenser outlet opening ~. A tubule 7 projects into the interior of the dome-like shaped headpiece 5 from the opening ~. The tubule is made of relatively stiff material and is held by a protrusion extending and formed from the headpiece cover 5' and pointing diagonally upward. The tubule is seated therein in a clamp ~S~3~i mounting, hu-t can, however, lf re~uired, be conrlected -to the headpiece by glue or even welding.
Equally possib]e is a one piece formatlon of the tubule 7 with the headpiece 5~
The tubule 7 is inclined at an acute-angle to the lonyltudinal axis y-y of the tubular or cylindrical housincJ 1. ~n this manner it projects with ;ts outer open end 7', forming the outlet ~, almost into the area o~ an extendiny cas:iny level of the housing 1. The inner open end 7" extends into the vicinity o~ the longitudinal center axis y-y, that is, into the center of the axially symmetric housing. It ends about level with the upper edge 6' of the neck and penetrates, as seen in Fig. 3, with this inner open end 7" into the pasty substance M, which comes up to under the dome shaped cover 5' of the headpiece 5, that is, the pasty substance also entirely surrounds the tubule~ Moreover, a portion of the tubule 7 is always filled with the pasty substance. The angle of inclination alpha of the tubule 7 relative to the axis y-y is approximately 30.
The zone forming the bellows B of the headpiece 5 is obtained by a horizontal flat-V-shaped constriction E. This constriction extends over half the cross-sectional width of the headpiece 5 which tapers frustoconically upward in its basic form. The furrow of the bellows is indicated with the numeral 9 and illustrated in Fig, 3 with a dashed line.
The acute-angled coordination of the tubule 7 in the section of the headpiece 5, opposite the constriction E, is such that the tubule 7 tips, by the bellows operation, so as to orient itself in a coaxial or approximately coaxial or spacial parallel position relative to the longitudinal center axis y-y of the housing 1. In this manner the outer open end 7' o~ the tubule 7 ~`~'?
~1~5~336 moves away from its usual position near the edge. The open end 7' can also be shaped in a more beak-shaped curv~d form in such a way that the opening ~ is perpendicular to the axis y-y.
The headpiece 5 is encased by a cap 10 shown partially in dot-dashed lines in Fig. 3. The inner corner of the cap cover is -tapered corresponding to the front surface posltion of the tubule, so that with the tapered cap 10 in position the tubule opening is tightly sealed. The cap 10 is held xictionally or locked in position by a complementary shaping of the parts at a peripheral bead in the fastening area of the same between the lower headpiece edge and the neck 6 of the housing 1.
The manner of operation of the described dispenser is as follows:
After removal of cap 10, the headpiece S is pressed downwardly in the direction of the piston 2 in the area forming the bellows B, which area is grooved like a tire or otherwise roughened on the upper side. The piston 2 is supported by the clamp module 3, so that ik cannot move or deviate downwardly. The pasty substance M
is pressed, while passing through the tubule 7, in direction of the opening ~ and finally discharges from the open end 7'. If the headpiece 5 is now released, vacuum pressure develops in the housing interior. The flexible headpiece 5, returning to its initial position, retracts or pulls the piston up in the direction of the arro~ x over the contents column. This resetting is completed before the substance still remaining in the tubule as a plug can reach the inner open end 7". Decisive thereby is that the tubule 7, in cross-section and length, with adjustment to the viscosity of the pasty substance and the resultant slow velocity, forms a corresponding resistance which bridges the occurring vacuum.
The ratio of the open tubule cross-section to the tubule length is approximately 1:5.
