Feb. 15, 1938. H. MocK COLLAPS IBLE TUBE Filed Feb. 10, 1957 N w MP4 Patented Feb.15, 1938 OFFICE COLLAPSIBLE TUBE Hugo Mock, New York, N. Y. Application February 10, 1937, Serial No. 125,013

9 Claims. This invention has for its object an improvement in collapsible tubes, and more particularly has for its object to provide a novel form of the collapsible tube of the type made from tin or lead or lead tin alloys.

A particular object of the invention is the provision of a newiorm of collapsible tube which is made with but a single opening and in which the base and body form an integrally closed element. A further object of the invention is the provision of a novel form of collapsible. tube in whichthe clamping device ordinarily'used to seal the ends of the collapsible tube at the present time is transformed into a device which not only seals one portion of the tube but also acts as the duct or opening through which the contents of the tube are extruded.

Further objects of the invention will be apparent from the specification and drawing, in which Fig. 1 is a perspective view of the ingot from which the body of the tube is made. a Fig. 2 is a side elevation of the completed tube as extruded from the die.

Fig. 3 is a side elevation of a completed tube with its ends compressed.

Fig. 4- is a sectional view along the lines 4-4 of Fig. 3. 4

Fig. 5 Ba plan view of the metal clamping device in extended or inoperative position.

Fig. 6 is a sectional view along the lines 6-6 of Fig. 5;

Fig. 6a is an end view of the clamping device in operative position, that is, after the sides have been turned over the ends of the tube.

Fig. '7 is a side elevation partly in section showing'the clamping device applied to the ends of the tube.

g. 8 is a sectional view along the line 8-8 of Fig. 7.

Fig. 9 is a side elevation of the completed tube with clamping. device attached and provided with a cap. 7 r

ll indicates the body of the tube having the ends or pressed-in portion I2, in the center of which a small opening I3 is left.

I4 is a clamping device which may be stamped out 'of sheet metal having the corrugations or projections anda neck l6 made integral therewith having a thread i1.

I8 is a cap internally threaded to fit the neck 86, which cap may be made of metal, synthetic plastic or any other suitable material.

I have endeavored inthis invention to provide a collapsible tube with only one opening, so after obtaining a tube I I by means 02 the die T and suitable form in order allel relation, and an forated so that the tube itself is both filled and emptied through the' same end of the tube.

After the walls of the'openend of the tube are compressed together, a small opening is left therein, for extruding the contents of the same when the tu is compressed, and said opening extends within the contiguous ends of the clamping device I 4 which is clamped over these compressed end walls by being bent along'the line G-6 shown in Fig. 5. The clamping deviceis preferably stamped from a sheet of suitable metal having a threaded neck l6 provided with 'an axial bore which is the opening -through'which the material in the tube is finally extruded. The opening I 3 in the tube is formed by providing opposed bulged portions 3a in the flattened end of the tube, as clearly shown in Figs. 3 and 7.

- The clamping member or clip I4 is initially flat,

as shown in- Figs. 5 and 6 with the neck I6 rising therefrom, and is then bent in U shape similar to the configuration shown in Fig. 6a, and at this time the opposed parallel legs of the clamp or clip M are provided with bulged portions l9 which are adapted to engage about the bulged portions l3a of the tube. I

The projections l5 may be corrugations of any to stamp the contiguous end'walls of the tubemore effectively, but may be changed or omitted without departing from the spirit of myinvention.

S shows the material or substance in the tube. The tube may be filled prior to compressing the open and contiguous end walls together or may be filled after the entire 'tube is completed.

. It is apparent that considerable economies are l effected by this form of tube in which the clamping device serves a. double function and a matter and more attractive tube is produced.

Having fully described my invention, what I, claim is: I

1. A collapsible tube having a cylindrical body and a rounded bottom closing said tube and integral with said body, the ends of the open portion of said tube being compressed together, said ends having confronting bulged portions, a clamping piece forcing said ends together in paropening in said clamping piece alining with said bulged portions by which the contents of said tube may be extruded.

2. -A collapsible tube comprising a substantially cylindrical body provided with one end thereof closed and the opposite end open, said opposite .bulged to provide a discharge opening, and a apart detents and a discharge neck engaging about said bulged wardly thereof.

3. In a clamping device for a collapsible a body of metal bent in the center thereof to form two adjacent side walls, an. opening in said body along said center, said side walls being concave adjacent said opening.

4. A clamping devicefor a collapsible tube comprising 'a clip fitting over the open and com pressed end of the tube, an opening in said clip, the walls of said opening being bulged so as to provide a passage through which the contents of the tube may be extruded.

5. In a clamping device for a collapsible tube, a body of metal bent to form two adjacent side Walls, an opening in said body in line with the edges of the open and compressed end of the tube, said side walls being bulged or concave ad- Jacent said opening. 7

6. A collapsible tube comprising a substantially cylindrical body having one end thereof compressed to provide parallel walls, said walls havportions and projecting outing an opening therebetween, a clip fitting over said compressed end and having an opening registering with the opening in said tube by which the contents of the tube may be extruded, a discharge member integral with said clip provided comprising a clip made of tube,

said clamping member disposed axially discharge member.

'7. A clamping device for a collapsible tube sheet material bent in substantially U-shaped form to compress one end of the tube, said clip having an opening therein and said tube having an opening registering with the opening in the clip through which the con-- tents of neck on said clip, and said neck.

8. A clamping device for a collapsible tube comprising a sheet metal body bent in the middle to form two adjacent side wa1ls, said body having a central opening, a cap formed on said body adjacent said opening and integral therewith adjacent said opening, said cap being threaded to receive a closure for said opening.

9. As a new article'of manufacture, a combined clamping and outlet means for a collapsible tube the tube may be extruded, a threaded a detachable closure for and a closure for said comprising a clamping member U-shaped in transverse section having a discharge opening in the bight thereof adapted to register with a discharge opening formed in the compressed walls of the tube, a neck carried by the bight of of said opening, and a cap for said neck, the parallel walls of said clamping member firmly gripping therebetween the compressed walls of said tube.
