Application August 14, 1950, Serial No. 179,366
' the screw threaded outlet end of the tube at which end the paste is dispensed, be connected with the device or appliance which I have invented, the filled tube housed therewithin by closing such appliance, and pressure applied at opposite sides against the tube to dispense or eject a desired quantity of toothpaste at the outlet end of the tube. And such dispensing or ejection may continue until all or substantially all of the paste within the tube has been used;
Other objects and purposes than those particularly stated, and novel structure for attaining the objects and purposes of the invention will appear and be understood, from the following description, taken in connection with the accompanying drawing, in which,
Fig. 1 is an end elevation of the dispensing apparatus or appliance of my invention, some parts being broken away and shown in section for a better disclosure, and
Fig. 2 is a longtiudtinal section substantially on the plane of line 2-2 of Fig. 1.
Like reference characters refer to like parts in the different figures of the drawing.
In the structure disclosed as a preferred embodiment of my invention, a housing is provided having two sections or halves one of which has an upper side I and the other a lower side I, from each of which spaced sides 2 extend toward each other, each housing part at one end having an end closure 3. The two parts of the housing, at the opposite ends of the upper and lower sides I thereof, are connected with a closure plate 4 for the opposite end, by a pivotal connection indicated at 5, so that the two halves of the housing may be swung apart about the pivots 5 as shown in dash lines in Fig. 2, for the placing of a tube containing toothpaste or other similar material therein, the screw cap closure at the outlet of the toothpaste tube being removed and the exteriorly threaded outlet end portion of the tube screwed into an interiorly threaded opening 6 centrally located through the end member 4. One end 3 of one of the members of the housing carries a spring latch member I which is adapted to releasably engage with the other end member 3, the latch extending 5 Claims. (Cl. 222-103) across the juncture between them as shown in Fig. 2, and seating in a recess adapted to receive it.
Each of the upper and lower sides I of the two housing members has an elongated opening 8 therein extending longitudinally of said housing members. Through such opening a member 9 slidably passes and at its inner edge is equipped with a pressure plate In permanently connected thereto in any suitable manner. At the outer end of each member 9, an enlarged head I] is connected or is integrally formed therewith, so that by grasping the two heads H in the hand or between the fingers and thumb of the hand, pressure may be applied against opposed sides of the collapsible tube to force its fluid contents out at the open end of the tube through the end member 4.
The interiorly threaded opening. 6 into which the outlet end portion of the tube is screwediis adapted to be closed by sliding closure plate' I2, mounted at the outer side of the end member 4 in suitable retaining guides I3 therefor. Such sliding closure l2 may be moved to its open position, as shown, when the toothpaste or other contents of the tube is to be dispensed and, preferably, is releasably held in either the open or the closed position by a spring actuated ball latch M, which is moved into recesses made at the inner side of the plate I2, there being two of such recesses spaced from each other, in one of which the spring actuated ball I4 is seated when the closure plate I2 is in open position, and in the other in which it is seated when closed.
The tube which is to be thus collapsed and its contents dispensed or ejected is indicated in dash lines at l5. It lies lengthwise of and within the closed housing. The housing parts are swung open about the pivots 5 to substantially the dash line position shown, the closure cap of the tube removed and the exteriorly threaded outlet end portion of the tube screwed into the opening at 6. The housing is then closed and will stay in closed position, being retained by the latch at I. The openings 8 will be sufficiently longer than the parts 9 which pass therethrough that a slight tilting of the pressure members may be had so as to exert pressure against the closed end portion of the tube [5 in the beginning so as to flatten the tube more at its closed end than at its outlet end to thus insure the greatest efficiency in getting the contents of the tube out of it. When one tube has had its contents dispensed, it may be removed and another put in its place.
The closure plate I2 is to close off the open end of the tube so that the contents at such open end do not harden, and also to insure against the dispensing of the contents of the tube accidentally or otherwise. The structure described is very useful, practical, is easily constructed and fully serves the purposes for which designed. The invention is defined in the 'appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
