CORPORATION OF NEW JERSEY INTERIOR COLLAR CAN Application 1ed lay 4,

The present invention relates to cans of the interior collar type in which the material of the bod is adapted to be severed beneath the top an the cover thereafter used as a temorary closure itting upon a separate colar secured within the u per part of the body.

A principal object o the invention is the provision of a construction of this character in which the collar may be secured in place in such manner as to prevent the leakage of liquids between the same and the can body, and this without the use of solder, or any other separate sealing medium.

A further object is the provision of a. method of assembling collar bands and can bodies, which, through very simple operations, produces a relationship between the parts attaining the foregoing result.

A. further object is the provision of an im proved body construction, which facilitates the formative operations and increases the eciency of the resultant structure. f

Other objects and advantages ofthe invention will be apparent as it is better under stood from the following description, which, takenin connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referrin to the drawings,

Figs. 2, 3 and 4 are detail sectional views the parts in the positions assumed showmg at the iiii'erent stages of the assembling op eration; and

Fig. 5 is a detail plan View of a part of the bodyl'lblank. j

e container as thus illustrated, comprises a body 21, to which is permanently secured a bottom end 22 and a top 23, which latter, pressed head or provided with parallel score in the present instance, 1s of the deplug variety. Said body is

lines

24 and 25,

the latter of which is disposed immediately beneath a seam 26 by which thecover 1s secured to the body. These score lines set off a tearing strip provided at one end with a tongue 27, which is adapted to be engaged bya key, or otherwise, for removal of the 1923. Serial No. 636,519.

strip. Diagonal score lines 28 are provided between the

parallel lines

24 and 25 and serve to direct the tear back to said lines, in the event it is deflected therefrom. A separate collar member 29 is positioned within the body, in accordance with the method of my invention, and extends from a point slightly above the upper score line to a point considerably below the lower line 24. Said collar, in the present instance, is formed with tight beads, or false wire edges, 31 and 32 at both the top and bottom, the former of which provides a shoulder within which the cover may be fitted after severance', and the latter of which is adapted to be expanded into locking engagement with the container body, as will now be described.

As shown, the bead 32 is ysubstantially solid and, when acted upon by an interior expanding die, is forced against the body 21 with such pressure as to expand the latter and form a groove 33 extending entirely around the circumference of the can. By this same operation, the bead 32 is, of course, bent outwardly from the position shown in Fig. 2 to that shown in Fig. 3, in which il, tightly engages within the groove 33.

After the parts are brought to the position shown in Fig. 3, the bead may be set up to the position shown in Fig. 4 by means of clenching dies, or other suitable apparatus, acting upon the exterior of the bead 34, which results from the formation of the groove 33, as heretofore described. The clenching dies may operate close to the body of the can and form definite shoulders 35 pressed against andholding the bead 32 at the top and bottom. This increases the eiliciency of the structure by further tightening the joint between the collar 29 and the can body 2l, and I have found that this joint effectively prevents the leakage of liquid between these parts.

My invention comprises the beading of a double thickness of the sheet metal of the collar member into the wall of the container body, thereby greatly stifl'ening the collar and also the body against distortion, and holding the collar more tightly and firmly in the body, as best seen in Figs. 3 and 4.

Figure 5 illustrates in detail the form, of

lock type, indicated by the reference char-` acter 36. The overlapping edge, however, is cut-away, as indicated at 37 and, in the area of the bead 34, is merely lapped over 'the opposing edge, as shown at 37', in Fig. 1.

This facilitates the bending of the metal at this point, which would be very dificult with the thicknesses necessary for a lock seam. An auxiliary lock portion 4.0 is provided above the cut-away part 37 beneath the tearing strip. It will beunderstood that the portion of the body above said strip is practically all interfolded in the double seam 26 and, therefore, a lock seam in this area is unnecessary.

The cover is seamed onto an upper body flange 38, in the usual manner, and is ,provided inwardly of the seam with a shoulder 39, resting upon the top of the collar bead 31, a vertical Wall part 4l being provided about a head portion 42 and being adapted to be e inserted within the upper end of the container in frictional engagement with the bead 3l. `With this construction, the cover may be used as a temporary friction plug closure, after removal of the tearing strip.

lt will be understood that my invention is not limited to use in a container having a body of cylindrical shape, but the body f the container may be of other shapes such as rectangular, polygonal, oval, etc.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts, without departing from the spirit and scope of the invention, or

- sacrificing all of its material advantages, the

form hereinbefore described being merely a preferred embodiment thereof.

l claim: v

1. A container, comprising a body having an end member permanently secured thereto and adapted to be opened by severance beneath said member, .and a separate collar positioned within the upper part of said body and adapted to receive said end member as a temporary closure after severance from the body, said collar being provided with a bead, or wire edge, expanded into liquid-tight locking engagement with the body and by itsexpansion forming a groove in the inner' face of the body.

2. A container, comprising a body having an end member permanently secured thereto and adapted to be opened by severance, beneath said member, and a separate collar positioned within the upperpart of said body and adapted to receive said end member as a temporary closure after severa-nce from the body, said collar being provided with a rigid 1,eee,435

-bodyin which the bead is disposed in liquid tight sealing engagement.

4. A container, comprising a body having an end member permanently double seamed thereto and adapted to be opened by severance ofthe body beneath said member, a se arate collar positioned and held within tlife upper part of said body and formed at its upper end with a friction closure seat, said end closure being formed with a friction plug closure seated in said friction seat. of the collar and removable after the severance of the body and afterwards replaceable as a friction closure, and said collar being formed at its lower end with a ring pressed outward into said body so as to form an outwardly projecting bead in the otherwise cylindrical surface of the body. l

5. A method of making can bodies which consists informing a body blank into cylindrical body shape with the ends of the blank attached together, and forming a corresponding collar therefor curled to form beads along its upper and lower edges and of a size to fit within said body, inserting said collar within the body and then applying internal pressure against the lower of said curlsand opposing resistance on the outside of the can body at the sides of the curl to form a peripheral recess within the body and to seat the collarv securely therein with a tight oint between said parts.

5. The combination of a container body of sheet metal formed with an interior cylindrical surface, and a sheet metal collar havp ing a substantially cylindrical bead the upper and lower portions of which form two thicknecesses of metal and said bead being pressed tightly into .the interior of the cylindrical surface of the body and thereby forming a bead on the body and a tight joint between said beads.
