3 Claims.

This invention relates to a device for dispensing dental or shaving creams or any other contents of collapsible tube type containers, and has for the primary object the provision of an eflicient and inexpensive device of this character which may be easily: and quickly operated to dispense the contents of a container in desired amounts and which is so constructed that the entire amount of the contents may be dispensed from the container, eliminating waste and the device further will permit easy and quick application or removal of the container therefrom and provides a support and a protector for the container.

Referring in detail to the drawings, the numeral I indicates an elongated squeeze plate having formed on opposite edges thereof the side walls 2 provided with elongated slots 3. Rack bars 4 are secured to the'side plates, and. ar-

ranged adjacent the slotsii. Integral with one end of the squeeze plate i is a bracket 4' includ ing angularly related portions 5 and 6. The portion 6 has openings 1 through which fasteners may pass for securingthe bracket to a. wall or like support. Also formed on the portion 8 are hooks 8 on which. may be suspended toothbrushes. The shapes of the hooks 8 are such that the toothbrushes will be. supported outwardly from the wall or like support. Connecting the angularly related portions 15 and 6 are bracing strips 9. The squeeze plate i is supported in a downward and outward direction with respect to the support or wall, as clearly shown in Figure 1.

A bottom plate I0 is provided on the squeeze plate i and extends at right angles thereto and has formed therein a slot ii to'receive the screw threaded discharge neck 12 of a container l3 of the collapsible tube type. One of the end walls of the slot II is beveled, as shown at [4,

' to engage in the screw threads of the discharge neck l2 for resisting upward movement of the container during a squeezing operation'thereon and which will be hereinafter more fully described.

is arranged on the squeeze plate and the bottom plate in an inverted position, that is, with the tail end disposed uppermost. The tail end is indicated by the character A.

A shaft l1 extends through the slots 3 and has secured thereon a squeeze roller l8 preferably constructed of cushioning material such as rubber. Sleeve journals i9 are arranged on the shaft I! to contact walls of the slots 3. Pinions 20 are secured on the shaft l1 and mesh with the rack bars, and finger pieces 2! are secured on the ends of the shaft.

The upper ends of the side plates 2 have notches 22 to be engaged by projections 23 formed on one end of a cover 24. The cover tioning of the container on .thesqueeze plate as described the roller is brought over the. end, A

of the container and by rotating. the. finger pieces the roller is causedto travelin a down-- ward direction forcing, or collapsin the con-, tam against the squ ze plat which..bring s about ing of thecontcnts of the container by way. of the discharile neck. II. It is to be understood that the can is removed. from the neck before rotatingv h finger pieces to bring about the squeezing operation. As the contents are substantially removed from the container by the downwardtravel of the roller the container assumes a flattenedposition, asshownin Figure- 5, with the dischars? end lying partly in the oiTset [5 of the bottom plate. The, container being permitted to move towards the squeeze plate during the final expelling of the contents permits the container to be'flattened through out its length so as to assure the complete ex- -pulsionof; the contents of the container; The

distance the rollerisadvancedalongthe squeeze plate governs, the, amount of the contents expelled from the container.

Referringto my :rnodifled form of inventionzthe u e pla e. side allsand slots thereof. and the bracket. are the same as described in. connection with the first form of the invention. In the modified formof the, invention they lower end of thesqueeze plate hasfomi d thereon a right angularly extension .2! having a.

series of corrugations 2.8. "lfhelower; ends ofths side plates. arefoii'set to form guides Ilto slid? ably receive a removable. bottom plate N; the

slot 29 thereof being constructed similarly to the slot ll. formed on the bottom plate. to engage with, the corrugations 2,601 the extension 2! .for adjusting the position of the bottom plate on the 'squeeze plate so as to'accomrnodate containers ofdifferent sizes. The extension, 30 by pressure thereon may be fiexedgso. as to permit it to be adjusted from one corruga tion to another.

In the modified form of my invention a shaft 3| extends through the slots 3. and the. pinlons 32 thereof mesh with the rack bars, on. the q z p a he ninions. "are sec redtothe.

The slots 31' being, curved form projections 43,

which aid in maintaining thepintles at either end of the slots. The purpose of mountingthe pintles 38 in the slots 3! is to. permit the hard roller 39 to readilypass over the tailend, of a. container positioned-0n the squeeze plate and as form a tumbler rack or holder.

said-rolleris advanced in a downward direction the pintles move to one end of the slots 31 or the ends. in the direction of the squeeze plate, the projections 40. acting to retain the pintles in said endsziof. the slots so as to bring about an eillcient squeezing a'ction of the roller on the container to expel. its contents.

Theportion .6 of the bracket I may be providedwithian .oil'sct H to removably receive one 'endof a bracket 42, the other end. of the bracket being integral with a plate-like member 43. The plate-like member has upstanding flanges ll to A portion of the plate fis oifset, as shown. at 45, and a slot 46 is mvlded at One end of the offset. The offset fljforms a'trough fordraining from the plate condensation: or water onto the portion 5 of the bracket. The portion I may be recessed, as shown st ll, to catch the drippings from the trough I.

Having describedthe invention, I claim:

1. A dispe sing device comprising a squeeze plate, a bracket for supporting said plate in a depending position, a bottom plate carried by the squeeze plate and having a slot to receive the discharge n'e'ckof a container resting against the squeeze plate, .one wall of the slot of the bottom plate being" beveled to engage'scrcw threads of the. neck to resist upward movement of the container, side-plates formed on the squeeze plate and having-slots, a. shaft extending through the on the shaft and meshing with the rack bars, carriage plates journaled on the shaft and having curved pintle slots, projections formed on said plates and extending intoythe slots of the side pintle slots, and a. roller, secured on said pintles.

2. A dispensing device comprising a squeeze plate, means for supporting said plate in a substantlallyvertical position, a corrugated extension formed on said squeeze plate, side plates formed on the'squeeze plate, a bottom plate slidably mounted onthe side plates at the lower end of the squeeze plate and having a slot to receive a discharge neck of a container resting against the squeeze plate, a hook-shaped extension formed on the bottom plate to engage with the corrugations for adjustably securing the bottom plate onto the squeeze, plate to accommodate containers of different sizes, said extension of the squeeze plate andthe hook-shaped extension of the bottom Plate. cooperating in forming a space for the reception of a portion ofthe container after being substantially collapsed throughout its.

endof the squeeze plate to receive a portion of thev container adjacent the neck thereof after squeezing of said container, and means movably supported on the squeeze plate to squeeze the container.
