NATIONAL CANTUBE CORPORATION INC., OF CHICAGO, ILLINOIS, A CORPORATION if OF DELAWARE CONTAINER The present invention relates to a container in which a pliable or flexible envelope is secured within a casing and which casing is provided with means for facilitating the l discharge of the envelope.

An object of the present invention is to provide an improved container for plastic substances. f

Another object of the invention is to provide a container in which a plastic substance may be retained and from which it may be` several elements illustrated in the accom-`- panying sheet of drawingsv in which two forms of the present invention are disclosed and in which: I

Figure l is a vertical section of one form of the improved container illustrating its general structure.

Figure 2 is a fragmentary section at right angles to Figure 1; and

Figure 3 is a vertical section of y,a second form of the invention.

Like reference characters are used to designate similar parts in the description and drawings. n

Reference should be had first to Figures 1 and 2. A casing 10 of cylindrical form is provide with a flanged top 11 in which a slip cover 12 is disposed, said cover carrying a4threaded neck 13 covered by a threaded cap 1 l An envelopev 15 of pliable material, i. e., waterproofed cloth, is secured between the cylinder and top 11, the crimping 16 providing a secure j oinder or attachment therefor. Any suitable plastic subtance may be inserted into the envelope through neck 13 or better by removing cover 12.

The bottom 17 of envelope 15 is suitably closed. In'the present instance said bottom is sewed at 18, the sewed portion providing a Application led May 16,

loop through which atransverse key 19 is threaded. Said key 19 extends diametrically across the bottom of thedevice in an elevated plane, the endsk 20 being downwardly bent to be seated in and secured to a bottom plate 21. i

A' Bottom. plate 21I closes an annular member 22 which has a constricted top section 2 3, the upper part of which,` is shouldered or beaded at 24 to be seated in and held within the bottom of cylinder 10'by a peripheral band 25 crimpedupon and about the edge of cylinder 10 so that the inner edge of said band 25 engages the annular shoulder or beading 24, thereby holding member 22 part'- ly within and freely rotatable upon cylinder 10.

to cylinder 10, as is hereinafter pointed out.y

yBy such rotation, the'envelope 15 is twisted from its b OttoIn upwardly, forcing the material confined therein, by "constriction, toward andrthroughneck I' .y y Y 4 As' Vthe twistingV of envelope lcontinues, the material adjacent'key'19 is first affected. Further twisting forces the bottom of the ,envelope to constrict, and eventually the material of he envelope 15 will become a. stiff cone, continually decreasing in altitude as member 22 is additionally rotated. Eventually all, or nearly all, of the material is forced vfrom the container.

f By a reversed rotation, the pressure on the material being expelled is reduced so that a part thereof may be retracted when exceslivedischarging.rotation has been initially 'The twisting'of the envelope 15 in a manner mentioned normally shortens the envelope. Additional length of tlie'envelope to'compensate for the shortening of the envelope by twisting is secured by the excess material at the betteln llf? of the envelope,

heretofore referred to. This excess material compensates for the amount of material taken up by the discharging twist.

In Figure 3, there is illustrated an envelope 115 of rubber or other highly flexible material. This `is disposed .in a casing 110, having `any suitable spout or neck 113 imposed upon a top plate 111. Cover 114 closes neck 113. Bag 115 is secured about the top of cylinder 11'0by crimping 116. The bottom of the device comprises the plate 121 and an annular member 122. These are crimped one to another to provide a beaded bottomperipheral edge.

The bottom of bag 115 may be closed but if not, *it` is sealed and secured to bottom plate 121 and member 122 by the crimping of the bag 11,5 therebetween, so that the bag 115 will be twisted when bottom 'members 122 and V121 are rotated relatively -to cylinder 110.

The structure of annular member 122 is substantially the same as that of part 22 except that buttons or detents 124 are substituted upon constricted section 123 for the continuous shoulder 24 rof Figures 1 and 2. A band 125 secures the cylinder 110 :and lthe annular member 122 in connected rotation admitting of relative rotary movement therebetween. With the relative rotation of said parte, bag 115 is .twisted and its contents remowed, the elasticity of the rubber .of said bag 115 compensating for the shortening of the material incidental to such twisting.

Having thus described the invention, what isclaimed as new is:

1. Acontainer for plastic material consisting of a rigid casing, a flexible envelope therein housed being rigidly attached to the upper end of the casing land having a plurality of folds of material wherewith it is attached to the lower end fof the casing, said lower end `of the casing being freely rotatable.

2. A container for plastic material consisting of a rigid casing, a eXi-ble envelope therein housed being rigidly attached to the upper end of said casing and having a plurality of folds terminating in a' loop, a freely rotatable bottom on said casing, and means for securing said loop to said bottom.

3. A container for plastic material consisting of a rigid casing, a flexible envelo e therein housed being rigidly :attached to t e upper end of the casing, said envelope being considerably longer than the said casing and being `provided with a pluralityy of folds at the end opposite to that attached vto the Vtop of the casing, said folds terminating in a loop, a freely rotatable bottom on said casing, Vand means for securing said loop to said bottom.

4. package for dispensing lplastic materia-l comprising a substantially rigid casing, a, flexible bag therein attached to the inner periphery ofthe dispensing end of said cas- JAMES E. GRMES.
