INVENTOR. Rn YMOND H. HORN/NG BY fi M14 64 United States Patent CONTAINER Raymond H. Homing, Fulton, N. Y., assignor to Gswcgo Falls Corporation, Fulton, N. Y., a corporation of New York Application August 13, 1952, Serial No. 304,139

3 Claims. (Cl. 229-55) This invention relates to paperboard containers and more particularly to paperboard containers of the type which are assembled at the packing plant. These containers are formed with a cylindrical body which is shipped in flat, collapsed condition. The body is expanded in tubular form, and the bottom closure secured to the container body at the packing plant.

This invention has as an object a container of the type referred to embodying a bottom closure structure which is quickly assembled to the container body without the use of an assembling machine and without employing any metallic fastening members, and which will not subsequently become separated from the container body.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

In the drawings- Figure 1 is a side elevational view of a container embodying my invention.

Figure 2 is a fragmentary sectional view taken on line 22, Figure 1.

The container comprises a cylindrical barrel or body formed of relatively heavy paperboard. The bottom closure is in the form of an outer disk 11 formed with a cylindrical flange 12 encircling the lower end portion of the body 10. A reinforcing band 13 of relatively heavy paperboard is adhesively secured to the flange 12 and extends an appreciable distance beyond the free edge thereof and is folded upon itself, as at 14, inwardly against the container body. As shown in Figure 2 of the drawings, the folded portion 14 terminates in abutting relation to the free edge of the flange 12.

The bottom closure further includes an inner discoidal closure 15 having a cylindrical flange 16 extending in parallel relation to the body wall of the container. A disk 18 of heavy stiff paperboard is inserted within the container and positioned upon the inner closure 15. The disk 18 is of greater diameter than the internal diameter of the body 10. The flange 16 is of such length as to position the disk 18 in registration with the edge of the folded portion 14 of the reinforcing band, and the disk functions to expand the lower end portion 20 of the container body outwardly against the flange 12.

"ice

Preferably, the reinforcing band 13 is formed of paperboard having appreciably greater thickness than the outer closure 11 whereby the free edge of the folded portion 14 forms a shoulder engaged by the expanded end portion 20 of the container body and whereby the bottom closure becomes mechanically interlocked with the container body.

Preferably, the inner closure disk 15 is arranged with the flange 16 thereof extending downwardly engaging the outer closure disk 11, the space between the

disks

11, 15, forming an insulating barrier for the disk 18.

With the structural arrangement described, the bottom closure can be assembled manually to the container body without the use of a machine, or any special tools, and when assembled the bottom closure is fixedly secured to the container body in such manner that the bottom closure will support the maximum weight which the container is capable of carrying.

What I claim is:

1. A container comprising a cylindrical body formed of paperboard, a bottom end closure formed of paperboard, said closure consisting of a discoidal portion positioned on the end edge of the body and having a cylindrical flange encircling the body, a reinforcing band of paperboard adhesively secured to said flange, said band extending upwardly from the edge of said flange, and being folded upon itself inwardly and downwardly against the body, the free edge of said infolded portion of said band engaging the edge of said flange, a second closure formed of paperboard positioned within the body on said first closure and having a cylindrical flange of less length than the flange of said first closure and extending parallel to and engaging the inner surface of the body, a disk of relatively thick paperboard positioned on said second closure, said disk having a diameter exceeding that of the interior of the container body and being operable to expand the end portion of the container body below the infolded portion of said band outwardly into engagement with the flange of said first closure intermediate the discoidal portion thereof and the edge of said fold.

2. A container structure as defined in claim 1 wherein the cylindrical flange of said second closure engages the discoidal portion of the first closure.

3. A container structure as defined in claim 1 wherein said reinforcing band is formed of paperboard having a thickness exceeding the thickness of the board from which said first closure is formed.
