11 Claims.

The invention relates to containers, and more particularly to a container consisting principally of paper board.

According, to one form which the invention may take, the container may comprise a substantially cylindrical body of paper board and a bottom structure having a substantially plane bottom and an inwardly extending conical rim. The lower edge of the body may be provided with slits forming fingers which may be spread outwardly within the rim of the bottom structure and held in such position by a suitable insert. In this way a positive interlock is obtained between the body and the bottom structure which eifectively prevents separation of these parts even when used to carry heavyarticles. The container may be made substantially cylindrical or it may be of conical form, in which case the containers may be conveniently nested for shipping in assembled condition.

The invention also consists in certain new and original features of construction and combinations of parts hereinafter set forth and claimed.

Although the novel features which are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, the invention itself, as to its objects and advantages, the mode of its operation and the manner of its organization may be better understood by referring to the following description taken in connection with the accompanying drawings forming a part thereof, in which Fig. 1 represents a body blank;

Fig. 2 represents a collar blank for making up the bottom structure;

Fig. 3 indicates a'circular sheet of soft material such as paper, cloth or cellophane;

1930. Serial No. 500,493

Like reference characters denote like parts in the several figures of the drawings.

In the drawings accompanying and forming part of this specification, practical commercial embodiments of the invention are shown, but as such illustrations are primarily for purposes of disclosure, it will be understood that the structures may be modified in various respects without departure from the broad spirit and scope of the invention as hereinafter defined and claimed.

Referring now to the drawings, and more particularly to Figs. 1 to 9, inclusive, the container shown in Fig. 7 is made from the blanks indicated in Figs. 1 to 6, inclusive. The body blank 20 comprises a body portion 120 slit to form a plurality of fingers at its lower edge. The body portions of the fingers are denoted by 123.and the nger ends are denoted by 23. The lines 21 and 22 indicate score lines for bending the fingers at these points, as will be hereinafter set 75 forth more in detail.

The bottom structure may be made up from a blank 25 shown'in Fig. 2 which comprises a rim forming band of paperboard, metal or other material 26. The band may be provided with fingers 80 2'7 separated from the rim portion by a score line 28. The band is out along curved lines as indicated so that, when it is bent to form a ring with its ends riveted or otherwise secured together, the resulting rim portion will be conical.

To assemble the bottom structure as indicated in Fig. 9 the disc 29 of paper is first laid fiat and the outer disc 30 is superimposed thereon. The collar 25 with its ends secured together by pasting or riveting, is placed over the disc 30 as indicated, with its fingers 27 bent inwardly. The paper or cellophane wrapper 29 is then bent over the top of the band 26, as indicated, and down inside so that it overlaps the fingers 27 at 126. The next smaller disc 31 is then forced into position shown to rigidly hold the parts of the bottom structure assembled. It will be understood that a suitable machine may be provided for assembling these parts, if desired.

To assemble the bottom structure and body, the I body blank 120 is curved to form a cylinder and its meeting edges are secured together in any desired way, as by rivets 125, as indicated in Fig. 7. The lower end of the body 20 is placed within the bottom structure, which is indicated by 33, with its finger ends 23 overlying the disc 31, as indicated in Fig. 8. The insert 32, which is smaller than disc 31, is then forced into position to securely lock the body 20 and bottom structure 33 together to form the completed container. 1

It will be understood that the disc 31 is larger than the inside diameter of the upper edge of the band 26 so that it must be forced past this point. The paper board material permits a certain amount of yielding both in the disc 31 and in the conical band 26 so that the positioning of the disc 31 is accomplished without rupturing any of the parts. At the same time the disc 31 firmly holds the end 126 of the wrapper 29 tucked in the position shown. In a similar manner the disc 32, while larger than the inside diameter of the tubular body 120, can be forced into position firmly to hold the finger parts 23 and 123 expanded against the adjoining parts of the bottom structure or closure 33. It will be understood that, if desired, the wrapper 29 may be adhesively secured to the disc 30 and band 26.

In some cases the middle disc 31 may be omitted, in which event the inner 'disc 31 holds both the fingers and the wrapper in position.

If desired, the closure shown in Fig. 9 may be made one piece instead of composite, as illustrated. In other words, the closure will comprise an end wall with an in-turned side flange integral therewith, both wall and flange being made .of

homogeneous fibrous or metallic material. This closure may be either moulded to form the construction just described, or it may be made in the same manner as any cylindrical paper board cover. Or, if desired, the closure may comprisea band member having an upstanding rim portion and an inwardly extending lip or flange portion of relatively stiff material, upon which the disc member 31 seats, to form the bottom of the container.

Referring now to Figs. 10, 11 and 12, the container herein shown is similar to that-shown in Fig. '7 except that it is made conical. The blank is denoted by 80, being cut in the shape shown so that when folded around to fasten its edges together, the shape will be conical. It is provided with finger parts 81 and 82 which cooperate with the bottom structure 84 to hold the parts in assembled relation in a manner similar to that described above in connection with Fig. 7.

If desired, the container may be provided with a bail 86 in which case a sheet metal member 85 may be conveniently secured to the body f0 securing the bail 86 thereto.

Thus, several specific embodiments of a conthey may be shipped in nested relation, one being placed within the other. The bottom structures or closures shown in Fig... 9 may, of course, be shipped either set up or knocked down.

It will be noted that the bottom structures or closures because of theirmanner of construction are quite rigid. When the closures are attached to the comparatively :yieldable body the rigidity of such closures imparts a substantial rigidity to the entire container, thus imparting strength to the set-up container and assisting it to withstand hard usage.

It will be understood that although a round container has been disclosed for purposes of illustration, the invention is applicable also to triangular, octagonal and other shapes. Further-- more, the insert discs, as for instance the discs 30, 31 and 32, may be of other materials than paper board, as, for instance, glass or celluloid, or other transparent material.

The containers above described are strong and durable and will carry heavy loads without weakening. They are also cheap, principally because they are made of paper board and are easily assembled or set up by the maker or shipper. They are particularly Well adapted for shipping large heavy contents in either solid or semi-solid condition. These containers may also be used for shipping coffee, cereal, crackers, hats, millinery, artificial flowers, cement, sugar, salt, cocoa and other contents. After material has been packed therein, the outward pressure thereby exerted on the side walls of the container maintains the fingers 123 bulged outwardly against the rim portion of the closure, and the insert disc 32 is then not further needed. If the container is packed while resting on its bottom closure the insert disc 32 may be entirely eliminated when certain kinds of material, which are hard, are packed therein.

While certain novel features of the invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes may be made by those skilled in the art without departing from the spirit of the invention.
