2 Claims. 1.
This invention relates to plastic material-dispensers for dispensing and applying plastic material, such as caulking compounds, putty, heavy greases, or the like, and has more particular reference'to a container or cartridge in which the" plastic material'is initially placed, said cartridgebeing adapted to-be used with a gun or applicatorof anypreferred type, but with which the cartridge is coordinated. 7
One obje'ctof the present invention is to pro"- vide a cartridge or container for plastic material, such-as caulking compounds, putty, greases, or the like, which may be filled by the manufacturer and delivered tothe'userfor use in a gun or applicator of any preferred type having means for holding the-cartridge or container while applying pressure to expel the plastic material through an-opening formed: in the delivery end of th'e cartridges- Another object of the invention is to provide a cartridge or container, as characterized above, having 'aspout or 'nozzle connected to its delivery end and having the entrance opening into the spout fromthe container or cartridge sealed oii bymeans" of a frangible film designed to be broken when; pressure is applied to the plastic material in the container to extrude it.
. Another object of the invention is to provide apre-filled cartrid'ge, as characterized above, in which'the spout is made of' a plastic material which may be colored to indicate the. color. of thecontents of the cartridge.
Aifurther-object ofthe'invention is to provide a p'rei-filled. cartridge," as characterized above, which-is so relatively inexpensive as to permit it" to be discarded after a single use, and "yet is sturdy in construction and eiiicient for its intended purpose;
Other objects and' advantages ofi'the invention will appear in the following specification. when considered in connection withthe-accompanying drawing, wherein:
Fig. 1 is a longitudinal central cross section, with parts omitted, showing a preferred embodiment of a cartridge constructed in accordance with the present invention;
Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1;
Fig. 3 is a detailed exploded sectional view showing the manner in which the sealing element is assembled in the spout; and
Fig. 4 is an elevational view, with parts broken away, showing the cartridge mounted on a gun.
In general, the present invention provided a discardable pre-filled container or cartridge for f 2, holdingplastic'material such as caulking com-:- pound, putty, heavy greases, or the like; adapted to be used with a gun or applicator of any pre ferred'type, but with which the cartridge is coordinated.
Referring now to the drawing, there is shown a preferred form ofthe invention constructed in accordance with the invention and comprising a cylindrical member or tube 10, havingone end closed by an end closure member ll carrying a spout 12; a sealing element assembly [3 mounted in the base of the spout; and'a movable piston closure member M for closing the other end of the cylindrical member.
The tube [0 and the endclosure or wall members II and I4 may be made of metal, plastic; or of anysuitable material. Preferably; and in the particularembodiment'of the invention illustrated, they are made of sheet metal, such as sheet tin. The delivery end of the tube! is closed by the end closure member II, which is fixedly secured to the end of the tube, as by crimping the peripheral edge of'the closure'memberon the peripheral end edge of the tube, as indicatedat l5.
The end closure member I! is shown as being a flat annular member having an annular indentation or recess lii'formed around the central opening IT in the'member and having its peripheral edges bent inwardly to facilitate crimping the member on the end ofthetube ill. An outwardly extending flange i8 is formed around the opening H for a purpose hereinafter to be explained.
The spout l2 :is shown as an open-ended tubular.member havingia:slight: taper from its inlet end toits outlet end and having its outlet end outed-obliquely to itslongitudinal axis (see Fig. 1). The spouti may be made of any suitable material,- such as'metal, paper, or plastic. In the: particular: embodiment of: the invention i1- lustrated ,.'the' spout is made of a molded or formed plastic material, preferably polythene, cellulose acetate, or cellulose butyrate.
The inlet end of the spout is provided with an outwardly extending lateral flange 19. The diameter of the flange i9 is made slightly less than the diameter of the annular recess l6 formed in the closure member H, and the thickness of the flange is made equal to the depth of the recess, so that when the spout is mounted in place in the end closure member II, as shown in Fig. 1, the inner surface of the closure member and the inner surface of the lateral flange I9 will form a flush-surface and wall for the tube ID. The
inlet end of the spout is counterbored, as indicated at 20, the bottom of the counterbore forming an internal circumferential shoulder 2| which provides a seat for an open-ended, flanged tubular sealing member 22. The sealing member 22 is preferably made of tin plate or sheet metal and has its outer peripheral edge bent or swaged. inwardly, as indicated at 23, to form a close fit with the bevelled seat or shoulder 2 I.
The inlet end of the spout is closed, as by means of a thin film 24, which is placed over the swaged end of the sealing member 22 before it is inserted into the spout (see Figs. land 3). The film may be made of any suitable material. In the particular embodiment of the invention illustrated, and preferably, the film is made of a film of polyethylene having a thickness of about .002 of an inch. This particular plastic film has a high tensile strength and is highly extensible, being capable of about 300% elongation, thus permitting the film to yield outwardly to prevent building up any back pressure in the cartridge.
When the spout is assembled on the end closure member I l, as shown in Fig. 1, it is secured thereon by crimping the outwardly extending flange 18 formed around the opening I! in the closure member against the outer side wall of the spout, thereby clamping the spout between the sealing member 22 and the flange 18. being made of a plastic material which can be made in various colors, may be colored the same color as the contents of the cartridge, thereby afiording the store-keeper and user a ready means of telling the color of the material in the cartridge.
The piston closure member I4 is placed in the filling end of the cartridge after it has been filled and'is shown in the form of a disc 25 having a peripheral fiange 26, the free edge of which extends rearwardly (see Fig. l).
The pre-filled discardable cartridge of the present invention, as described above, may be used with any of the usual types of guns or applicators now in use. For example, it could be fitted in the barrel of a gun of the type shown in Patent No. 2,115,591, for Gun for Discharging Plastic Compositions, issued to W. E. Sherbondy, on April 26, 1938, or it could be used with an applicator such as that disclosed in Patent No.
The spout,
2,481,711, for Extruding Applicator for Caulking Compound Cartridges, issued on June 3, 1947, to C. Moots et a1.
In the particular embodiment of the invention illustrated, the tube I9 is shown as having a plurality of cir-cumferentially spaced outwardly projecting lugs 21 formed adjacent to the filling end thereof. This construction permits the cartridge to be connected by a bayonet slot connection to a slotted socket 28 carried by the stock 29 of'a gun of the type shown in the patent to Sherbondy, cited above. When used with this type of gun, the cartridge is firmly held on the gun stock by the bayonet slot connection and the material in the cartridge is extruded through the spout, after the plastic film has been broken, by the trigger 30 advancing the operating rod 3| in the usual manner.
Obviously, the invention is not restricted to the particular embodiment thereof herein shown and described. Moreover, it is not indispensible 1 that all of the features of the invention be used conjointly, since they may be employed advantageously in various combinations and sub-combinations.-
What is claimed is:
1. A cartridge for use with guns for dispensing plastic material comprising an elongated tube; a disc-shaped end closure member secured to one end of the tube, said closure member having an opening formed therein; a dispensin spout having a laterally extending flange formed on its inlet end and an internalcircumferential shoulder formed therein intermediate its ends, said spout projecting through said opening with its flange engaging the inner surface of said closure member about said opening; a frangible sealing film extending across the opening in the spout at said shoulder; an open-ended tubular sealing member wedged within said spout with its outer end holding said film against said shoulder; and a movable disc-shaped end closure member closing the opposite end of the tube and adapted to serve as a piston to eject the contents of thetube through the spout.'
2. A cartridge, as set forth in claim 1, wherein the opening in said closure member is provided with an outwardly extending flange having its free end crimped against the outer surface of the spout opposite said sealing member to clamp the spout between said flange and said sealing member.
