(01. 221-60) This invention relates to paste dispensers espe- and includes substantially rectangular-shaped \cially adapted for dispensing dental, shaving or end plates 9 connected by, rods l0 andv also having facial creams without soiling the hands of the user and-has for the primary object the pro5 vision of an efficient, durable and inexpensive device of this character which will support and journaled in openings thereof a shaft II, one end of which extends through the slot 1. The extended end of the shaft has a ?nger piece I2 6 secured thereto. The shape of the plates 9 of the protect from. foreign matter a collapsible tube frame 8 is such that the frame will be free to \' or container and its contents and has a simple slide in the casing but will be held against a manually actuated means to compress the tube ' rotary motion within the casing. Journaled on 10 for expelling the contents thereof in amounts as the rods II] are sleeves I3. The sleeves have 10 desired. mounted thereon cushion rollers M. The shaft With these and other objects in view, this in-. II is positioned above and between. the rollers vention consists in certain novel features of con- and has a slot l5 to receive the non-open end of struction, combination and arrangement of parts 15 to be hereinafter more fully described and claimed. the tube 6. In other words, the non-open end of the tube is passed through the slot l5 and bent 15 into engagement with the shaft it after being For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which 20 Figure 1 is a front elevation partly in section illustrating a dispenser constructed in accordance with my invention. Figure 2 is a side elevation illustrating the passed between the rollers It so that upon rota tion of the shaft H the container will be wound on the shaft in a substantially flat condition, the rollers acting to compress the container or tube 20 and consequently expel therefrom the contents. By controlling the rotation of the shaft II the amount of the contents expelled from the con device.

Figure 4 is a sectional view taken on the line 42-43 of Figure 1. through the closure 3 of the casing. A seat I‘! is formed in the valve housing and. is engaged by a shoulder it formed on an elastic sleeve l9 which ' extends out of the valve housing.

Figure '7 is a detail vertical sectional view illus3'5 trating amocli?ed form of valve. Referring in detail to the drawing, the numeral I indicates a casing having secured to its rear wall one of the sections of a wall clamp 2 while the other section of the clamp is fas- slightly larger than the interior diameter of the sleeve 19 so that said sleeve tightly ?ts the ball and thereby forms a valve closure for the neck 5 of the tube 6. The ball 20 is mounted on a 35 rod 2| and the latter is secured to the ?ange I8 of the sleeve I!) by a cross rod 22. When pres sure is applied to the contents of the tube, the contents expands the sleeve l9 and passes about 40 tened to a wall or the like of a room so that the ball 20 to escape from said sleeve and as 40 the casing will be supported in a vertical position. The bottom of the casing is in the form of a removable closure 3 held on the casing by soon as the pressure is released on the tube the sleeve l9 contracts against the ball so as to close the contents of the container against atmospheric spring catches 4 engaging in openings provided conditions and foreign matter. 45 in walls of the casing. The bottom of the casing has an opening to permit a discharge neck 5 of a collapsible tube 6 to extend therethrough when said tube is arranged in the casing in an in; verted position. 5O A side wall of the casing has formed therein a slot 1 which opens outwardly through the‘ lower end of the casing and is normally closed at said Instead Of using the type of Valve as Shown in Figure 6, a type as Shown in Figure '7 may be 6m ployed and consists of a valve housing 23 having a bore 24 extending therethrough and a por tion of which is screw threaded to thread onto 50 the neck 5. A valve element 25 of the plug type is journaled in the valve housing Band has 9. port 26 which may be positioned into and out of lower end of the casing by the closure 3.. A frame 81s slidably mounted in the casing I communication with the bore 24. A handle 21 is secured to the valve element 25 whereby the 55 55 2 I‘ .' ' I _ 2,110,868 valve element may be rotated to open_or close the valve housing 23. _ When either of the valves, as shown in Figures 6 and 7 is applied to the neck of the tube 6. it will prevent said tube from becoming disarranged in the casing I and provides a simple means which will permit the easy removal and replacement'of a tube in the casing when desired. What is claimed is: 10 l. A' paste dispenser comprising a vertically arranged casing having a removable bottom pro vided with an opening to receive a neck of a collapsible tube with the vlatter arranged in an‘ inverted position within said casing, a frame slid 15 able in said casing, said casing having a slot, spaced cushion rollers carried by said frame and receiving therebetween the tube, a shaft jour naled in said frame and extending through the slot and having a slot to receive one end of the tube, a ?nger piece secured to said shaft where by the tube may be wound on the shaft to bring about expelling of the co tents of the tube by the rollers, a valve housing threaded onto the. 25 ' neck and against the cover and having a seat, an elastic sleeve extending out of said valve housing and having a ?ange to engage the seat, and a - ball supported in the sleeve and of a diameter slightly greater than the interior diameter of the sleeve. 2.
