There is a suitable conduit located above the pouch and in engageable communicating relationship therewith, the conduit having an elevated and transversely offset exit outlet which is provided with a slidable closure, and a manually operatable pressure plate (and preferably co-reciprocatable with the conduit) for expelling flowable viscous-material from the compressible pouch and thence ultimately through the conduit exit.

6 Claims, 3 Drawing Figures PATENTEQ m2? m5 SHEET DISPENSING APPARATUS FOR TOOTI-IPASTE DENTIFRICE AND OTHER FLOWABLE VISCOUS- MATERIAL There are in the prior art numerous dispenser apparatus for flowable viscous-materials such as toothpaste dentifrices and the like. For toothpastes, dispensers of the prior art are structured around the so-called conventional toothpaste tube" supply of the toothpaste which extend longitudinally along the vertical-axis and have a threaded discharge-opening at one end and a transversely linear crimp at the other end. For such conventional toothpase tubes," which annularly surround the vertical-axis in regular cross-sectional size and shape, the longitudinal vertical length greatly exceeds the average cross-sectional dimension (usually the circular diameter) and this lengthiness imposes structural limitations upon the dispenser apparatus therefor. Moreover, prior art dispenser apparatus are apt to be deficient in that the viscous-material is very apt to solidify at the exit outlet in the presence of atmospheric air, which solidification disables the apparatus thereby necessitating laborious cleaning and repair thereof. Also, the required structural features of prior art dispenser apparatus tend to result in primarily utilitarian appearance which lacks the aesthetic appearance appropriate for modern elegant bathrooms.

It is accordingly the general object of the present invention to provide novel dispensing apparatus for flowable viscous-materials, and particularly for toothpaste dentifrices, which is of reliable and economical construction and that is of unusual structural nature to provide unexpected and challenging opportunities for aesthetically pleasing apparatus designs.

It is another object to provide dispenser apparatus that is usable over an indefinite period of time. In this vein, the viscous-material supply is expendable and replaceably removably associated with the apparatus framework, the apparatus conduit means is in reliable free-flowing relationship with the expendable pouch supply, and the apparatus exit outlet is not apt to be clogged even if the viscous-material employed be solidifiable in the presence of atmospheric air.

It is a further object to provide novel expendable pouch-like supplies of toothpaste dentifrice and to dispense the toothpaste therefrom in an unusually reliable, fastidious, and aesthetic manner.

With the above and other objects and advantages in view, which will become more apparent as this description proceeds, the dispensing apparatus for toothpaste or other flowable viscous-material generally comprises: a hollow receptacle member extending upwardly along a vertical-axis and including upright wall-means surrounding said vertical-axis and an enlarged mouthopening for replacement of an internally positioned shallow pouch supply of dispensibly flowable viscousmaterial; the said pouch supply being provided with a discharge-opening and being manually compressible through externally located pressure-application means whereby viscous-material is caused to be expelled through the pouch discharge-opening; a conduit for the viscous'material in communicating relationship with the pouch discharge-opening and including an exit terminus located remote from the pouch and also generously transversely offset from the receptacle verticalaxis; and closure means for temporarily covering the conduit exit.

In the drawing, wherein like characters refer to like parts in the several views, and in which:

FIG. 1 is a perspective view of a preferred, though non-limiting, embodiment A" of the dispensing apparatus for flowable viscous-material and particularly toothpaste dentifrice.

FIG. 2 is a sectional elevational view taken along lines 2-2 of FIGS. 1 and 3; and

FIG. 3 is a sectional plan view taken along line 3-3 of FIG. 2.

Embodiment A" of the dispensing apparatus shown in FIGS. l-3 generally comprises a hollow receptacle 10 extending upwardly along a vertical-axis 9 and wherein the receptacle mouth-opening is positioned at the upper end 13 thereof, a replaceable expendable pouch supply of the flowable viscous-material herein as dentifrice 109, conduit means 40 having an entrance end 41 communicating (as with tubular fitting with the pouch discharge-opening 104 and also an exit end 42 transversely well offset of verticalaxis 9 and too from pouch discharge-opening 104, closure means such as the resiliently yieldable slidable C- shaped tongue 60 for the conduit means exit 42, manually exertible pressure-application means located externally from pouch supply 100 such as pressing-plate 50 for expelling the viscous-material 109 from the pouch discharge-opening I04 and eventually through the conduit exit terminus 42.

At the outset is is to be emphasized that the pouch 100 supply of dispensible viscous-material, such as flowable toothpaste dentifrice 109, represents a radical departure from so-called conventional tubes of toothpaste." Such conventional toothpaste tubes DO: extend longitudinally uprightly along a vertical-axis, have an upper discharge-opening, the tubular supply does surround the tube vertical-axis in regular annular crosssectional size and shape, and the tube dimensionally along its vertical-axis does bear a many-fold multiple ratio as compared to its average cross-sectional dimension. In direct counterdistinction, to the conventional toothpaste tube" supply currently sold in sundries departments, the pouch type container supply of flowable toothpaste dentifrice of the present invention (e.g. 100) is of exceedingly shallow height. That is to say the pouch container average cross-sectional dimension exceeds the container height along the own vertical-axis. For example, as alluded to in the three drawing Figures wherein the thin-shell pouch 101-103 carries is full capacity of flowable viscous-material (e.g. dentifrice 109) therein, said shell at 101 circularly surrounds a vertical-axis 9 and the circular cross-sectional size thereof is substantially uniform between its two transversely extending extremities e.g. roof-panel 103 and floor-panel 102. Herein, the annular 101, the floorpanel 102, and the roof-panel 103 parts are singularly constructed of a resinous plastic or other compressible structural material, and the herein horizontal roofpanel 103 is provided with a discharge-opening 104 surrounding vertical-axis 9. The pouch supply 100 which is preferably removably positioned within a receptacle portion 10, and thus expendably replaceable with an interchangeable expendable pouch supply after the dentifrice 109 is fully expelled therefrom, is desireably integrally provided with a co-expendable tubular fitting at the pouch discharge-opening 104. For example, upright tubular fitting 105 has an axial bore 106 along vertical-axis 9, the fitting upper portion being provided with external helical threades. The lower portion of fitting 105 has two horizontal flanges 108 and 107 respectively surrounding the bore 106 and verticalaxis 9, the flanges being tightly secured to the intervening pouch roof-panel 103 at discharge-opening 104. It is therefore readily apparent that the exertion of man ual pressure against the thin-shelled 101-103 pouch supply will cause the viscous-material 109 contained therein to be expelled along vertical-axis 9, as upwardly through the pouch discharge-opening 104105.

The hollow receptacle for removably containg the pouch supply includes upright wall-means surrounding both said pouch supply 100 and the vertical-axis 9 and includes an enlarged mouth-opening 13 for inserting and removing the pouch supply 100. Moreover, there are transversely extending base-means intersecting the vertical-axis 9 for resting the pouch floor-panel 102 thereagainst. Herein, hollow recpetacle 10 is of a rectangularly boxy configuration including four interconnected rectangular planar upright-panels llA-llD which together provide a rectangular upper'mouthopening 13 for receptacle 10. If the dispensing appara tus A" is to be employed resting downwardly against a tabletop, rather than being sidewardly attached to come columnar fixture, the receptacle base-means desireably comprises a horizontal planar panel as its lower end, herein as rectangular base-panel 12. It can be seen that the vertical height 12-13 for receptacle 10 is drastically less than the horizontal spacing of uprightpanels 11A11D or llB-ll C.

It is the general purpose of a suitable conduit means to convey the flowable viscous-material (109) in first the vertical and then in the transverse directions from the pouch upper discharge-opening 104-105 toward a final exit opening. Preferably, the conduit means has a lower entrance opening 41 at vertical-axis 9 and has an upper exit opening 42 that is generously(and herein forwardly) transversely offset of the vertical-axis(9). The conduit 40 of FIGS. 1-3 is of generally seven shaped configuration, its vertical stem lying along vertical-axis 9 and its lower end 41 threadedly engaged with the upper end of tubular fitting 106, and with its transversely extending elevated stem progressively narrowing toward conduit exit 42.

There are suitable pressure-application means located externally of said pouch supply 100 to permit the apparatus operator to apply manual pressure vertically against the pouch, causing the contained viscousmaterial 109 to be expelled upwardly through its discharge-opening 104105 and thence ultimately to the transversely offset conduit exit 42. The preferred type pressure'aapplication means comprises a transversely extending pressing-panel that is vertically reciprocatably associated with the receptacle member. For example, the horizontal rectangular pressing-panel 50 overlies the pouch supply 100 just slightly below receptacle mouth-opening 13 and being slidably associated with the planar interior walls of the respective wallpanels 11A11D. It is desireable to have vertically resiliently yieldable spring means for the pressing-plate, such as a helical spring 59 surrounding fitting 105 with its lower end bearing against upper flange 108 and with its upper end bearing against pressing-plate 50. Although it is possible to construct a conduit means 40 that could be at vertically immovable constant elevation, for economical and practical reasons both the conduit and the pressing-plate might be singularly con structed of the same structural material, such as the resinous plastic alluded to in FIGS. 2-3. With such unitized conduit and pressing-plate construction, herein collectively referred to as 20, they are covertically reciprocatable. Moreover, as also indicated in FIGS. 2-3, the said unitized construction 20 might be augmented with integral webbed portions into an aesthetically pleasing and utilitarian dome-like contour, best seen in FIG. 1.

Fingers of an operators left hand(assuming he be right-handed) appear as phantom lines 80 in FIG. 3 and at the instant he is just commencing to initiate downward manual pressure upon pressing-plate 50. It can be appreciated ffrom FIG. 2 (though not graphically en cumbered with a descended phantom line position for pressing-plate 50) that a manually initiated downward movement for pressing-plate 50 will compress the pouch supply 100. Thus, viscous-material such as dentifrice 109 will be forceably ejected upwardly along vertical-axis 9 into conduit 40 and finally out exit orifice 42 to fali onto the bristles of an awaiting toothbrush 70.

Many viscous-materials and including toothpaste dentifrices tend to solidify and become non-flowable when exposed to atmospheric air. Specifically, the den tifrice 109 is apt to become inimicably solidified at conduit exit 42, whereupon the dispensing apparatus A would be rendered inoperative until laboriously cleaned at said exit 42. Accordingly, the dispensing ap paratuses of the present invention desireably include some type of closure means for temporarily closing the conduit exit outlet after each dispensing operation. Thus, the closure means effectively closes the conduit exit for an indefinite time period until the dispensing apparatus is to be used again.

The preferred closure means is desireably affirmatively connected to the conduit means, and in this vein, a flap hingedly attached to the conduit immediately adjacent to the exit opening might be employed. Preferably, however, the closure means takes the form of an elongated C-shaped tongue 60 slidably engaged with the conduit and the pressing-plate and including an apertured portion 63 temporarily alignable with the conduit exit outlet 42. There are spring means 65 normally urging the tonge 60 so that its solid non-apertured por tion is normally aligned with the conduit exit to function as an interim closure therefor. For example, C shaped tongue closure 60 has an upper end 62 and an L-shaped lower end 61, tongue 60 being slidably associated along a single C-shaped grooved track having two portions 44(along the forward-upper side of con duit 40) and 54(along the upper forward side of pressing-plate 50). As best seen in FIG. 2, the flanged lower end 61 of tongue 60 carries a pin 64 along 54, and a helical spring 65 surrounds pin 64 and bears against the rearward end of pressing-plate grooved part 54. Thus. as seen in solid line in FIG. 2, spring 65 normally tends to urge tongue lower end 61 in the forward direction whereby the aperture 63 of tongue closure 60 is rearwardly offset of conduit exit 42. However, as indicated in phantom line in FIG. 2, whenever the operator pushes the toothbrush rearwardly against tongue lower end 61, spring 65 to compresses rearwardly and thereby allowing tongue 60 to flex and to slide sufficiently for aperture 63 to be aligned with conduit exit 42. At this juncture, the operator moves pressingplate 50 downwardly to force dentifrice 109 to fall downwardly through aperture 63 onto toothbrush 70. Upon operator withdrawal of the toothbrush, the spring 65 causes tongue 60 to resume its normally closed position, indicated in FIG. 2 solid line.

From the foregoing, the construction and operation of the dispensing apparatus will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
