PASTE-TUBE.

Specification of Letters latent.

Patented Mayld, 1918.

Application flled June 28, 1917. Serial No. 176,996.

To all whom it may concern:

clear, and exact description.

This invention relates to containers of the flexible tube type especially adapted for containing paste, although it is not limited to this use.

The object of the invention is to provide a. new flexible or colla sible container, and also a new method of filling the same.

A more specific object of the invention is the provision of a single-piece flexible container made of transparent celluloid in which-the material can be filled through the mouth instead of through the open bottom, as is commonl the case. To carry out this method the tu e is closed at the bottom and the body of the tube is then collapsed, and while in this condition the paste or other material is forced in through the mouth under pressure, whereby the tube is distended, and since.the wall of the tube is trans arent it is possible to ascertain whet er or not the full charge is supplied. The tube being of celluloid thecontents cannot be aifected deleteriously, as is liable with a metal'tube.

For a more complete understanding of the invention reference is to be had to the following description and claims taken in connection with the accompanying drawing which illustrates certain embodiments of the invention and wherein similar characters of reference indicate corresponding parts in all the views, in which Figure 1 is a side view of a tube; 4

Fig. 2 is a view taken at right-angles to Fig. 1, with a portion in section;

Fig. 3 is a similar view showing the bottom closed in a different manner from that in Fig. 2;

' for binding the closed bottom of the tube shown in Figs. 1 and 2- I Fig. 9 is a sectional view on the line 99,

Fig. 2; and

ig. 10 is ,a detail sectional view of a mclgdified form of the closed bottom of the tu e.

Referring to the drawing, 1 designates the body of the tube, which is made from tubular stock of celluloid which is transparent and pliable. The tube is formed at one end into a neck 2 and mouth 3, both of which are yielding or collapsible, which fea ture enables the contents of the tube to be forced out to the last drop. The bottom of the tube may be closed in any suitable man ner, as for instance, by cementing the two opposite sides-of the tube together as at 4, Fig. 3, or two semi-circular sealing members 5 and 6, as shown in Figs. 6 and 7,

may be employed. The member 5 has a longitudinal tongue 7 which is adapted to enter in a longitudinal groove 8 in the member 6. These members are made of celluloid, and the bottom edge of the tubular bod while the latter is in circular cross sectional shape, is cemented to the members 5 and 6, and then the latter are flattened out so that the two members interlock. These members can be cemented together, and further security can be obtained by applying ametal or other clip 9 which is constructed as clearly shown in Fi 8. The mouth of the tube can be closed by suitable construction.-

In Fig. 10 is showna'modified method of closin the bottom of the tube. One-half of the tu e has a'groove 10 on its inner surface and the other half has a tongue 11 which engages in the groove, and a metal or other cli 12 clamps the two halves of the tube tig tly together, said clip being of U-shaped cross section and having its opposite walls shaped to fit the outer surfaces of the walls of the tube, whereby the clip is prevented from becoming loose or pulling oif.

To fill the tube the latter is flattened so as to force out the air, and then while in this condition the mouth of the tube is connected with a nozzle, tube.or other supply device through which .material is forced under pressure into the tube. Since the wall of the tube is transparent it is easy to ascertain whether or not the roper supply of material is delivered to t e tube. v

a stopper of any From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the article which I now consider to be the best embodiment thereof, I desire to have it understood that the article shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A tube of the class described comprising a resilient tubular body having a contracted neck terminating in a mouth, said neck and mouth being resilient and adapted to return to their original shape after being compressed.

2. A tube of the class described comprising a resilient tubular body having a contracted neck terminating in a month, said neck and mouth being resilient and adapted to return to their original shape after being compressed, said neck, body and mouth being in one piece.

3. A tubeof the class described comprising a tubular body, clamping strips having longitudinal tongue and groove interlocking means for closing one end of the tube, and a clip engaging over the strips to hold the same together.

4. A tube of the class described con1prising a tubular body, clamping strips having longitudinal tongue and groove interlocking means for closing one end of the tube, and a clip engaging over the strips to hold the same together, said clip having inwardly extending flanges engaging the said strips to retain the clip in place.

5. A tube of the class described including as a one-piece article a body, neck and mouth made of resilient, transparent material, the neck and mouth being compressible as Well as the body.
