8 Claims.

- This invention relates to containers and to a method of making same.

In the packing of products for the market, the cost of an adequate container must be kept as low as possible if the purchaser is to receive the maximum of value in the product purchased. Where the container is made by one manufacturer and shipped to the packer, as is often the case, the cost of the container to the packer and finally to the consumer is greatly influenced by shipping costs of the container. .If the containers are so made that they do not permit of collapse or nestled packing, the shipping and storage charges of the empty containers is often very high and even may be prohibitive. Then the container must be so designed as to permit economical manufacture. In addition, the container must be adequate in strength to withstand all the rigors of use, and so made as to fully protect and preserve the contents. All of these factors must be taken into consideration if the consumer is to receive maximum value in useful merchandise for money expended.

In the packaging of many products, such as fruits, canned goods, liquids, ice cream and frozen products, cereals, hardware, groceries or any other commodity, wood or metal cans and containers have been used. Such metal cans and other containers are expensive to manufacture, ship and store and greatly influence the cost of the packed product to the consumer. In the packaging of looseice cream in quantities of from one to ten gallons, for example, metal containers only have been used since these containers must be very strong and sturdy to carry the heavy frozen product. These cans are very expensive to manufacture and ship in the first instance and after the frozen cream contents have been removed they must be gathered together by the retailer or consumer, and shipped or returned to the ice cream plant. Then they must be -washed, sterilized and cleaned before they are again ready for use, all of which adds considerably to the price of the ice cream product. Furthermore, the empty, unwashed cans require considerable storage space, attract flies, and apt to produce an unsanitary condition in and around the ice cream plant. Records must also be kept of the containers delivered, returned and to be rea container which is unusually sturdy and strong in construction, and which will carry the weight of heavy materials and withstand the rigors of rough handling, which is economical to manufacture, .which fully protects and preserves the contents, and which can be made attractive and pleasing in design and appearance.

Another object of my invention is to provide a container so shaped as to permit close nestling, one container within the other, which is light in weight and which is furthermore provided with means for firmly retaining a closure cover thereon.

Still another object of my invention is to provide a method for manufacturing the container above described economically and quickly with unskilled labor, and with inexpensive tools and equipment.

Other objects of this invention will become apparent as the disclosure proceeds.

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, and the manner in which it may be carried out, 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 shows a blank from which the barrel or body portion of my container may be formed;

Fi 2 shows a cutout blank from which the bottom portion of my container may be formed;

Fig. 3 is a face view of my body forming blank as it appears during one stage of the'containerforming operation;

Fig. 4 is a transverse cross sectional view of the body forming blank in the form shown in Fig. 3, this view being taken on line 44 of Fig. 3;

Fig. 5 shows the body portion and bottom portion of my container as completely formed and ready to be assembled together;

Fig. 6 shows the barrel and bottom portions of my container in the process of assembly;

Fig. 7 shows another step in the process of assembling the bottom portion and barrel portion of my container;

Fig. 8 is a vertical cross sectional view through the completed container;

Fig. 9 is a perspective view of a container of somewhat modified shape but having the general structural features of the container shown in Figs. 5 and 8; and

Fig. 10 is a cross sectional view through a plurality of my containers as they appear when nestled together.

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

A barrel forming blank 10 is cut in the general arcuate shape shown in Fig. 1. This blank may be made of fibrous, paper board or cardboard material, depending upon the use to which the container is to be put. If the container is to carry liquid or semi-liquid material, or materials which deteriorate through contact with the air, I prefer to wax-the fibrous material on the inside or the outside of the container, or both, or use a moisture-proof board. The blank is provided with a score line 11 which is spaced 9. short distance from and parallel to the lower edge of the blank, defining the lower edge portion 15. A score line 12 spaced a short distance from and parallel to the upper edge of the blank, defines the upper edge portion 14.

In forming the container, 1 bend the top edge portion 14 and the lower edge portion 15 inwardly so as, to overlap the main body portion of the blank, as shown in Figs. 3 and 4, which is done while the blank is still extended. The top edge portion 14 is bent so that it will be disposed on the outside of the finished container. The blank 10 is then shaped into barrel or tubular form, as shown in Fig. 5, with the side edges 20 and 21 of the blank overlapping. These edges can then be wire stapled as at 22 or thread sewn together, as desired. In the manufacture of some classes of containers which do not require a lid portion the top edge portion 14 can be eliminated altogether.

The bottom portion of the container is made from a disc shaped blank 16, as shown in Fig. 2. The disc shaped blank may be made of the same material as the barrel portion 10,.or it may be made of a stronger or more durable material, such as metal, if desired. The bottom blank 16 is provided with a flange portion 17 defined from the main bottom portion by score line 18. The flange portion 17 may be notched at various points along its periphery, as at 19, so that the flange can be bent downwardly into the general form shown in Fig. 5.

As the next step in the container-forming operation, the bottom portion 16 is placed on the end 23 of a conical shaped block 24, asshown in Fig. 6. The bodyportion of the container, bent into tubular form as' shown in Fig. 5, is then plugged down over the conical shaped block 24, as shown in Fig. 6, until the top edge of the flange 17 is in line with the scored line M. The flanges 15 are then turned in and over the lugs or flange 1'7. When the desired fit has been obtained between the bottom portion 16 and the body portion 10, and while the container is still on the forming block 24, the flanges 17 of the bottom portion may be stapled or sewn to the inturned edge portion 15 and the body portion of the blank, as shown in Fig. 7. This stapling --or stitching operation can be quickly performed by automatic machinery. The completed container may then be removed from the forming block and nestled together with similar containers as shown in Fig. 10.

The container may also be made without stitching or stapling along the lower rim by simply turning the flange 15 inward and over the lugs 1'1 which allows the lugs 1'1 to rest in the recess formed by the flange 15 and the inside of the body container. In such cases the notches 13 are not cut out of the flange 15, the weight of the contents when placed in the container being sumcient to keep the bottom portion 16 in position. This type is particularly useful for packing solids, ice cream, and other materials.

It will be noted by referring to Fig. 7 that the top flange portion or rim 14 does not hug the side walls of the container, but extends downwardly in plumb vertical position. The downturned rim 14 presents an excellent seat for any cover 26 which may be used, since the vertical flanges 27 of the cover will seat smoothly and tightly against the rim. The difliculty of providing a close fit between a conical container and the cover therefor is thus satisfactorily solved in an inexpensive and economical manner. The downturned rim portion 14 also provides a stiflening flange around the top of the container which greatly strengthens the same and prevents inward collapse of the side walls. Furthermore, the rim portion 14, spaced from the side walls, as shown in Fig. 8, provides an excellent finger grip for lifting and handling the container.-

The bottom of the container is strongly constructed and is provided with a three ply rein= forcing rim at the bottom. The bottom portion of the container presents a smooth continuation of the side walls. Containers can thus nestle closely one within the other, as shown in Fig. 10, so that a large number of containers can be stored or shipped in a very small space.

I have shown in Fig. 9 a container of polygonal shape which may be formed from a blank similar to Fig. 1, except that radiating score lines are provided which form the corners 28 of the body portion of the container. The bottom and top edges of the blank are arcuated polygonally rather than in circular form as is the case of the cylindrical container. The bottom portion is also of such a shape as to conform to the side walls, but the general method of making the cylindrical, the polygonal, or any other shaped container is the same.

It is now seen that I have provided a container which may be made into a number of pleasing forms and designs without affecting the structural strength or efliciency thereof. The containers are so made as to closely nestle one within the other, thus economizing in shipping and storage costs. It is usually strong and sturdy and adequately reinforced where the strain is the greatest. The container is provided with a substantially leak-proof bottom and thus can be used to contain frozen liquid and semi-liquid materials, powdered or granular goods. The container can be manufactured by automatic machinery at such low cost as to permit with economy the discarding of the container after having once been used for packaging bulk ice cream, or any other commodity. The unsanitary packaging of ice cream, for example, in returned metallic containers which-require the keeping of records, large storage space, washing and cleansing, during which time they are attractive to flies and other vermin, is thus economically overcome.

While certain novel features of the invention have been disclosed 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.

What is claimed is:

1. A container having a. conical portion forming the side walls of the container, and a reinforcing rim extending around the outside of the larger end of the conical portion and formed integral therewith, said rim being bent into position while said side walls are still in blank extended form.

2. A container having a conical portion forming the side walls of the container, and a reinforcing rim extending around the outside of the larger end of the conical portion and formed integral therewith, the side face of said rim extending substantially at right angles to the plane of said larger end, said rim being bent into position before said side walls are shaped into conical form.

3. A containerhaving a conical portion forming the side walls of the container, and a reinforcing rim extending around the outside of the larger end of the conical portion and formed integral therewith, said rim being spaced from the side walls of said conical portion to provide a finger grip by means of which the container may be lifted and moved, said rim being bent into position before the side walls are shaped into conical form.

4. A container having a conical portion forming the side walls of the container, a rim extending around the outside of the larger end of the conical portion and formed integral therewith, said rim being bent into position before the side walls are shaped into conical form, and a cover having a downwardly extending flange adapted to telescope over said rim.

5. A container having a conical portion forming the side walls of the container, a rim extending around the outside of the larger end of the conical portion and formed integral therewith,

and a cover having a downwardly extending flange adapted to telescope over said rim, said rim being so shaped as to closely fit within and contact the free edge of said flange and bent into position before the side walls are shaped into conical form.

6. A container having a conical portion forming the side walls of the container, a rim extending around the outside of the larger end of the conical portion and formed integral therewith, and a cover having a downwardly extending fiangeadapted to telescope over said rim, said rim being spaced from the side walls of said conical portion so as to provide a finger grip and to closely fit within and contact the free edge of said flange, said rim being bent into position before the side walls are shaped into conical form.

7. The method of assembling conical containers which includes, cutting out the blank to form the side walls of the container, scoring the upper edge of said blank to provide a rim portion, bending said rim portion outwardly and downwardly, and then securing the side edges of said blank together to maintain said blank in tubular form, and securing a bottom member to the lower end of said tube.

8. The method of assembling conical containers which includes, cutting out the blank to form the side walls of the container, scoring the upper edge of said blank to provide a rim portion, bending said rim portion outwardly and downwardly, rolling the blank into conical tubular form so as to cause said rim portion'to expand and assume a' vertical cylindrical position, securing the side edges of said bank together to maintain the blank in conical tubular form, and securing a bottom member to the lower end of said tube.
