COLLAPSIBLE CONTAINER.

Application filed February 24, 1925, Serial No. 11,037, and in Canada June 13, 1924.

This invention relates to collapsible containers, such as are disclosed by Patent No. 1,504,920, which issued August 12th 1924, which containers are adapted for holding tooth paste, shaving cream, face cream, and

articles of a like nature.

The particular object of the present invention is to improve and simplify the construction of such containers which are adapted to In essentially a single use, which can be readily stated, illustrated in the accompanyingdrawings, wherein are shown improved em to hodiments, but it is to be understood that changes, variations and modifications may be resorted to without departing from the scope of the invention.

In describing the invention in detail, reference is had to the accompanying drawings which form a part of this specification and wherein like characters of reference indicate corresponding parts throughout the several views, in which,

Figure 1 is a side elevation of an oval shaped, open-ended shell for receiving a portion of material, which afterwards is to be sealed therein;

Fig. 2 is an edge elevation of the same;

Fig. 3 is a top plan view of the open end of the shell; a

Fig. 4: is a side elevation of the shell with the end completely closed and sealed;

Fig. 5 is an end elevation thereof;

Fig. 6 is a side elevation of the shell, wherein the upper portion has additional sealing crimps;

. Fig. 7 is a side elevation of a slightly modified embodiment of the container;

modified embodiment of the invention;

Fig. 9 is an edge elevation of a portion of the container shown in Fig. 8 on an enlarged scale; I

Fig. 8 is a side elevation of a still further Figs. 10 to 16 are side elevations of furtheir modified embodiments of the container, an 1 Fig. 17 is a perspective view illustrating the manner in which the contents .of the contalner is squeezed out.

The body of the container embodying this invent on may be of any suitable form, such as cylindrical or oval in cross section, but 1n the embodiment shown in the drawings the shell has been shaped to an oval cross section.

4 Referring to Figs. 1, 2 and 3, a shell 10, having a rounded, closed lower end is shown. This shell is in the nature of an open-ended capsule of an oval shape and is in condition to receive the contents to be placed therein and sealed.

In Figs. 4 and 5 is shown the oval shell having its upper part, through which the filling takes place, closed by permanently folding over the corner parts 11, leaving an outlet 12, through which the contents may be discharged, which outlet 12 is then crimped and pressed together.

Fig. 6 shows also a body of oval form, which upper both sides and tips are crim ed along as is shown by 18, and the open e ges 12 are pressed together. For closing these open side edges 13, they are double crimped tightly together. The opening 12 is only crimped asingle time so that a relatively small, but properly applied pressure releases it.

In Fig. 7 is shown a slightly modified construction, wherein the shell 14 is formed of tubular material with the lowerend 15' folded over and permanently pressed against the sides of the tube so as to permanently seal the lower end thereof. The upper portion of the tube is closed after the material is inserted therein by folding over the corners 16 and pressing together and crimping the opening 17 in the manner above set forth. The tube may also be doubly crimped as indicated at 18, in addition to the folded corner 16.

In Fig; 8 the container comprises a shell side of the tube and the edges are pressed together with single crimp 21 therein, the major portion of the tube from the opening 20 to the otherside is provided with double crimps 22 and the outer edges may be folded overon to the tube for further securing the tube closed. As shown, the folded portion interlocked in a permanent manner by folding as indicated at 23 and 24. The interlocking of the walls in the various embodiments herein described may be accomplished by crimping, folding, rolling, perforating, stam )ing, stencllmg, soldering or other approvet ways-according to the degree of locking or fastening of the walls desired for the diiferent portions of the containers.

In Fig. 10, a container comprising a shell 25 formed in the same manner as the shell 14 disclosed in Fig. 7 is employed. This container is closed by folding the side portions 26 together leaving an opening 27 be tween them and pressing the portions of the opening together and providing a single crimp 28 for sealing the opening.

The container 29 disclosed in Fig. 11 is of similar construction and has its end 30 closed by folding the side portions of the tube together as indicated by 30 after the tube is filled. It will be seen in this form of tube that by pressing the sides of the container the folded portion 30 thereof will release and allow the contents to be ejected.

A similar container shell 31 is shown in Fig. 12. In this embodiment the end of the tube is rounded and portions of the sides of the tube are folded upon each other as indicated by 32. By pressing the sides of this container, one or more of the folded portions 32 will yield and permit the contents to be ejected.

The container 33 shown in Fig. 13 is constructed the same as that shown in Fig. 12

except that the end of the tube is provided with opening 34 between folded sections 35. In this form of the container the walls of the opening are pressed together and provided with a crimp 3G.

The container 37 shown in Fig. 14 is constructed similar to that shown in Fig. 8 and is provided with a cap member 38 which is adapted to slide over the folded closure portion 39 and opening 40.

In Fig. 15 the container 37 is provided with a spring clip 41 which operates to seal the end of the container in a similar manner as the cap 39. When it is desired to remove the contents from the container, the cap 39 or spring 41 is first removed from the container.

- In Fig. 16, a container 42 of similar construction is disclosed having its end 43 sealed by folding the side portions of the tube upon themselves in locking engagement. This closure is provided with a wire reinforcing member 44 extending throughout the locked folded portion acting as a reinforcing member and has an exposed end 45 which may be grasped and drawn outwardly in a manner to tear the portion 46 or so much of the end 43 as is desired to provide an opening through which the contents of the tube may be ejected. In addition to the folding of the end 43, this tube may also be provided with crimps 21 and 22 which maintain the container sealed after the removal of the wire 44.

In Fig. 17 a tube constructed in the manner set forth is shown with the contents being ejected therefrom by pressing the sides between the thumb and finger. By means of such construction a single application container is provided, which cannot in any manner become unsanitary and which avoids many of the objectionable features of tubular containers now in use.

The material of the tube can be made of any suitable material, the form or shape can be round, square, oval or flat; the size depends upon quantity of contents, though preferably only one application is intended.

Containers embodying my invention maybe readily taken along on traveling trips and when used, are thrown away. Such containers are particularly applicable for medical and surgical uses, in that they provide antiseptic means for each dose and when made of a suitable material, the discharge ends thereof can be readily sterilized before being used, and thereafter the contents discharged.

While several embodiments of the invention have been shown and described, it is clear that changes may be made therein without departing from the spirit of the invention as defined in the following claims.
