Claims. (Cl. 229-55) This invention relates to an improved article of manufacture, and the methodof making the same from any appropriate sheet material, such as paper.

A principal feature being to build up a container structure with the aid of shapers or mandrels, from pieces of a pre-formed and scored sheet blank, appropriately divided into relative component parts for conjunctive assembly to form the bodies and covers of containers able to withstand a maximum service and o f such lowcost to encourage its use for heavy duty in an article of this type. l

A principal object'of the present invention is to provide a complete substantially fluid-proof container, including a body portion` and a cover, each having means, in the walls thereof, for effectively reinforcing the structure to withstand the destructive action of fluids or other contents for an unusual length of time. v

A further object is to provide a method for making reinforced containers for many purposes,

including drinking cups, from pre-cut parts of a single rectangular sheet of material with absolutely no waste pieces of material remaining, thus resulting in high economy and super-strength in an article of the laminar type.`

- Suitable means, such as a powerful fluid-proof adhesive, may be employed'to unite the builtup parts in forming the container, drinking cup or the like; the adhesive being applied to advantageous or desirable areas on the several portions of a sheet blank at the time the cutting is done to prepare the parts for use, if desired, or said ad- -hesive may be applied to an entire face of each of said parts or t0 an entire face of the said sheet blank, before the cutting operation.

For the sake of simplicity, there is shown and described a container of rounded or cylindrical conformation, in cross section, but, of course, various cross-sectional or general shapes may be adopted and no limitation is intended by the phraseology of the above statements of invention or in the following description in detail, with reference to the drawings, illustrating one form of the invention, which show the container as having vertical parallel side walls, but said container may be formed with flaring walls (not shown) to provide a drinking cup or other useful article of that general shape, or other practical shapes.

In the drawings illustrating one preferred form of our invention, Fig. 1 is a partial sectional side elevation of a container constructed according to what we now believe to be a good form of our invention, the walls being broken away to better disclose theconjoining of the parts but in exagerated relative dimensions.

Fig. 2 is a partial horizontal section on broken line 2--2 of Fig. 1.

Fig. 3 is a horizontal section taken on the broken line 3-3 of Fig. 1.

Fig. 4 is a partial horizontal section, taken on the broken line 4-4 of Fig. l.

Fig. 5 is a fragmentary View taken on the line 10 5-5 of Fig. 1.

Fig. 6 is a face view of a paper or other sheet blank divided into pieces o1'. portions providing the material from which the improved container is constructed by a method lof sequential step operations.

Figs. 7, 8, and 9 are diagrammatic views showing, respectively, the rst, second and third operative steps in the method of forming a container of the type described. go

Fig. 4l() is a fragmentary section showing an additional disk-piece between ythe layers 2| and 2 Ia, of the bottom to reinforce the same.

Referring now to the drawings in detail, the improved container body I0, as in Fig. 1, comprises a cross-sectionally cylindrical side wall II, a bottom I2, and a separate removable cover I3, having atop I3a; the cover being of a size to fit snugly around and over the mouth or open end I4, of the container.

Our method of building the improved container I0 consists in first supplying a sheet blank (Fig. 6) of proper size and contour so that no'stock waste remains. This sheet blank I5, being divided or cut as at I6, into pieces or portionsgl! to be assembled and united as hereinafter set forth:

In 4carrying out the invention, one face of the sheet blank may be entirely coated with a suitable adhesive as at I8,`or the edges only of the pieces or portions I1, may have applied thereto lines of adhesive, as at I9.

In thelpresent form, the identical portions 20, 20a and 20h may comprise, collectively, the laminated 3 ply side Wall II of the container shown in Figs. 1 to 5 inclusive, and the identical parts 2| and 2 Ia, collectively may comprise the laminated 2 ply bottom I2 of thesaid container. V

The identical portions or pieces22, -22a and 22h of the sheet blank I 5may comprise in a general sense, the side wallV I 3b of the cover I3 of the container, and the identical parts or portions 23 and 23a of the sheet blank I5, may collectivelycomprise the top I3a of the cover I3, as hereinafter described.

the

The circular bending lines of the bottom poritons 2l and 2 la, and the top of the cover portions 23 and 23a, are indicated at 25 on the sheet blank I5, 'and outward ofv these circular bending lines are short and longer reinforcing portions 26 and 21, which, in the assembling operation, areturned inwardly between the respective side walls of the container body and its cover to reinforce the corners, and the side walls for some distance from said corners, as clearly shown in Figs. 1 and 5 of the drawings.

By referring to Figs. 1 and 3 of the drawings, it will be seen that the short and longer reinforcing portions 26, 21 of the top and bottom parts yor layers, are placed in diametrically staggered relation, to lie at eight diametrically opposite points in the side walls, so that the reinforcement of said walls is extended further at eight equally spaced areas, and of course the shapel and size of these longer reinforcing extensions may be varied if desired or required, or the reinforcements in the walls of the container and its cover may be of other forms.

The blank pieces for forming the bottom and top layers of the container are here shown as squares of sheet material, the corners of vsaid squares and the narrower portions therebetween being turned upwardly or inwardly between the side walls toI serve as the reinforcing extensions vof said top and bottom pieces of the blank I5,

as will be evident.

Suitable mandrels or forms 30 and 3| may be supplied, on which the wall portions 22, 22a and 22h and 20, 20a and 20h may be rolled alternately with respect to.` the application and bending the reinforcing portions of the top layers 23 and 23a' and the bottom layers 2l and 2la inwardly and against the side of each progressive wall portion or layer to be permanently interposed in the wall structures, as best shown in Fig. 1, of the drawings. g

Briefly, with reference to Fig. 6, a body wall piece 2Gb, is rolled around the mandrel 3l; its

vends overlapping and sealed as at 24 in Fig. 2,

after which, a square bottom piece 2|a is placed in proper position on the cylinder thus pro-duced and is engaged by a suitable cupped die 3m, which turns the reinforcing portions 26-21 inwardly or upwardly into contact with the outer lower Wall portions of they portion or piece 2Gb; a second wall piece 20a is then applied, rolled and sealed over the last described pieces, after which, a second bottom piece 2l, is applied by the cupped die Sla, and finally another wall piece 20 is rolled and sealed over the laminated wall and bottom described, thus providing a 3 ply wall and a 2 ply bottom in a container, and

finally this structure may be hard pressed, with or without heat, making a hard, rigid body portion which will stand up yunder long hard service.

The cover I3 for the container body I0 is con- 5 structed in the same manner by using the mandrel 30 and a cupped die SIb, see Fig. 7.

Of course it will be understood that for high speed production, power driven means or mechanism may be employed for assembling, shaping 10 and uniting theccmponent parts of the laminar container and its cover, above described, and as shown in the accompanying drawings.

In the claims, the body and cover collectively will be termed container, unless otherwise l5 designated, and since the body and cover are constructed by the same method, a claim for forming the body only will be submitted.

In Fig. 10, of the drawings there is shown a disk-piece 5D, placed between the bottom layers 20 2| and 2 la to reinforce the same, if required, and a similar disk-piece may also be located between the layers 23 and 23a for the purpose set forth.

What we claim isz- I 1. A container comprising side and end walls 25 of multiple sheet paper, the sheets of the side walls being one greater in number than the end walls; the sheets of the end walls having triangular reinforcing extensions interposed respectively between the inner sheet and the next our sheet 30 of the side wall and between the next outer sheet and outer sheet of the side wall of the structure, said reinforcing extensions being permanently fixed in cross wall staggered relation and in circumferential equidistant positions between said 35 sheets.

2. A container comprising laminated side and end walls; the lamin of the end walls each having four corner extensions interposed between the respective center and side lamin of the side walls 40 in alternate cross-wall and annular staggered relation to add strength to the said side wall.

3. A container comprising an odd number of side wall layers and an even number of end wall layers of sheet material; the end wall layers havi5 ing prolonged corner portions interposed respectively in staggered relation between the side wall layers of the container at opposite sides of the center layer and within the other layers of said wall. 50

4. A container comprising a side wall of layers and end walls of layers, each layer of the end walls being provided with four diametrically opposite reinforcing corner portions extending from the end walls and interposed between the side 55 wall layers of the container in respective staggered relation at opposite sides of the central layer of said side wall. I

5. A container comprising a laminar side wall of three layers and laminar end walls of two 60 layers, the layers of the end walls being provided with corner portion extensions interposed between the layers of the side wall in respective annular and cross-wall staggered relations.
