This invention relates to paste dispensers, and more particularly to a dispenser attachable to a wall to hold a collapsible tube of tooth paste or similar material, and operative to dispense the paste from such a tube for use.

It is among the objects of the invention to provide an improved paste dispenser of highly sanitary character, which can be formed of a ceramic, metallic or synthetic resin plastic material, and which can be easily attached to the wall of a room, such as a bathroom, which will contain an entire tube of material, such as tooth paste, and will progressively dispense the contents of such a tube until the tube is entirely empty, which has a tube closure cap automatically movable to open position while material is being dispensed from the tube, and automatically closed by the action of resilient means when the dispensing operation is discontinued, and which is strong and durable in construction, simple and economical to manufacture, and neat and attractive in appearance.

Other objects and advantages will become apparent from a consideration of the following description, and the appended claims, in con junction with the accompanying drawing, where- Figure 1 is a front elevation of a tooth pastedispenser illustrative of the invention;

Figure 2 is a longitudinal cross-section on an enlarged scale of the dispenser illustrated in Figure 1, and is taken substantially on the line 2-2 of Figure 1;

Figure 3 is a transverse cross-section taken substantially on the line 3-3 of Figure 2;

Figure 4 is a longitudinal cross-section of a fragmentary portion of the dispenser, and is taken substantially on the line 4-4 of Figure 3;

Figure 5 is a longitudinal cross-section of a fragmentary portion of the dispenser on a still further enlarged scale, and is taken substantially on the line 5-5 of Figure 3; and

Figure 6 is a transverse cross-section on an enlarged scale of a fragmentary portion of the mechanism llustrated in Figure 3.

With continued reference to the drawing, the tooth paste dispenser comprises, in general, a base iii, a backing member l l pivotally connected at its lower end to the base, a compression spring l2 resilently urging the upper end of the backing member outwardly of the base, a cover member :3, pivotally connected at its upper end to the base, a catch assembly is for the lower end of the cover member, a closure cap [5 for closing the neck opening of a collapsible paste force of the spring l2.

4 Claims. (01. ate-96) tube positioned in the dispenser, and a torsion spring 16 for resiliently urging the closure cap IE to open position.

The base [0 is of rectangular shape, and has a pair of spaced-apart, substantially-parallel, continuous side walls I7, and a back wall structure comprising an upper portion l8 and a lower portion l9, joined at their edges to corresponding edges of the side Walls to hold the side walls in their spaced-apart, substantially-parallel relationship and substantially perpendicular to the back wall structure. Ihe base also comprises a bottom wall 20, extending outwardly from the bottom of the back wall structure along the bottom edges of the side walls. This bottom wall is curved upwardly near its edge remote from the back wall, to provide an upwardlyfacing, downwardly and inwardly-inclined edge 29, and is provided with an elongated, beveled opening 22 to receive the neck 23 of a collapsible tooth. paste tube 24 received in the dispenser, the longitudinal center line of the opening 22, being disposed substantially perpendicular to the back wall structure IS.

The backing member H is a rectangular plate receivable between the side walls ll of the base In, andtapering in thickness from its lower to its upper end. Near its lower end, this backing member is pivotally connected to the base by a pivot pin 25 extending transversely through the backing member and through the side walls of the base. Near the upper end of this backing member, the side walls are provided with respectivaarcuate guide slots 26, and the backing member is provided near its end with projections 21 in the form of pins, extending through V the corresponding guide slots 26 to limit outward movement of. the backing member away from the rear wall structure of the base under the The upper portion I8 of the rear wall structure, and the backing member H are provided with spring-retaining extensions 28' and 29, respectively, received in the opposite ends of the compression spr ng E2 to hold the spring in operative position between the backing member and the rear wall structure of the base. The spring I2 is of conical form to permit the upper end of the backing member H to closely approach the rear wall.

The cover member 53 is also a rectangular plate, preferably of tapering thickness toward its ends, and is longit dinally curved near its upper end to extend from the outer edges or the side walls, back substant ally to the rear wall structure l8, and is pivotally secured at its upbears end of the cover member outwardly-away -f-rom the back wall structure. When the tube 24 is properly mounted in the dispenser, as illustrated in Figure 2, the lower end of the cover member it may be manually pushed inwardly to squeeze the tube between this cover member and the backing member to force the desired quantity of tooth paste, or other material, out of the neck 23 of the tube, which neck is received in the opening 22 of the bottom wall.

The closure cap it is preferably a rectangular structure underlying the bottom wall 20 in covering relationship to the opening 22, and is provided on at least three sides with marginal flanges constituting two sides 3! and a front end wall 32. A lining 33 of cork, or some similar resilient material, is provided in the cap E5 to contact the end of the tube neck 25 to seal the paste in the tube when the cap is closed.

The sides iii of the cap are extended somewhat rearwardly of the bottom plate 34, and are apertured to receive a pivot pin 35, which extends through apertured lugs 35, provided on the base it) below the bottom wall 28 to pivotally connect the cap to the base.

The bottom wall 20 is provided with two elongated siots 37, disposed one slot at each side of the opening 22, and a pair of spaced-apart, substantially-parallel links or arms 38 extend respectively through the slots 37. Corresponding ends of the arms 38 are pivotally connected to respective sides 3! of the cap by respective pivot pins 39, disposed somewhat forwardly of the pivot pin 35. The arms 38 are received in respective notches it in the outer edge portion of the bottom wall 29, and extend somewhat outwardly of the bottom wall. A thin walled resilient catch 4! is secured at its ends to the outer end portions of the links 38, and is provided with a ridge 42, which operatively engages the lower end of the cover member I3 to hold the cover member against movement outwardly of the outer edge 2i of the bottom wall 26. The catch l can be depressed, however, to release the lower end of the cover member so-that the cover member canbe swung outwardly and upwardly about the axis of pivot pin 38 to give access to the interior of the dispenser for the replacement of a paste tube.

The arms 38 are releasably held in the respective notches 40 by corresponding lugs 43, projecting inwardly from the side walls, and the cap it is resiliently urged to its opened position, indicated in dotted lines in Figure 2, by the torsion spring it. This spring has two arms 44 provided at their outer ends with hooks engaged respectively with the lengths 38, and has loops overlying the inner surface of the bottom wall 3 of the cap to urge the cap downwardly about th pivot pin 35.

With this arrangement, when the lower end of the cover member [3 is forced inwardly to compress the tube 24 between the cover member and the backing member II, the catch 4! is released by the cover member, freeing the links 38 4 so that spring [6 is effective to swing the closure cap from its ciosed to its open position. A tooth brush may then be disposed below the neck of the tube to receive tooth paste forced from the tube. It will be noted that there will be sufficient space between the cover plate and the tube to permit complete opening of the closure cap before the cover plate comes into contact with the side of the tube. As soon as manual pressure on the lower portion of the cover plate is released,

spring i2 pushing against the upper end of backing member ll, forces the cover member outwardly, and as soon as the lower end of the cover member strikes the ridge 42 of the catch 4!, it pulls on the links 38 in a direction to return the closure cap to its closed position, sealing the end of the tube neck 23.

The upper part of the rear wall structure is provided with suitable apertures for screws 45,

or other suitable fasteners, by means of which the dispenser can be firmly attached to a wail, and respective apertured extensions 46 are provided on the outer sides of the side walls [1 of the upper ends of the latter to provide racks for tooth brushes 41.

The elongated shape of the opening 22 permits the neck 23 of the paste tube to move toward the rear wall structure of the base as the contents of the tube are progressively dispensed, as shown in dotted lines in Figure 2, so that the device is operative to flatten the entire length of the collapsible tube and substantially empty the tube.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.
