W E. BENSON CONTAINER Filed May 2, 1927 Patented Dec. 31, 19 29 WILLIAM .EVERETT BENSON. OF-WOLLASTON, MASSACHUSETTS, ASSIGNOR OE (INE- HALF TO THEODQRE M.

PRUDDEN, 0F HINGHAM, MASSACHUSETTS CONTAINER Application -fi1ed May 2,

. -My present invention relates to improvement in containers by which I am able to produce a side wall of great strength and with many advantages. In forming the side walls of paper containers, it has become usual practice to overlap the wall edges in order. to get a sufficient strength to withstand usage. Y

This seamed construction has disadvantages both structurally and as a matter of factory methods. The presence of the old lapped seam is particularly disadvantageous in the case of inserted bottom containers or where atop closure or cover is used. It also makes'trouble in the external decorating or the printing of advertising matter on account of the extra thickness at the seam. My present invention relates to a container wall structure by which various advantages are gained and the seam avoided and by which certain advantages are gained, aswill later more fully appear.

While container types vary considerably, I have selected as an'illustrative form ofembodiment of myinventionthe flaring wall container as it is generally considered as the most difiicult type to produce on a commer-' cial basis in a degree of perfection. The application of the principles thereby illustrated to other types will be made so readily bythose skilled in the art that the illustration of modifications and variant is not believed necessary.

In the drawings: 7 Fig. 1 is a sectional view of atwo ply-container.

Fig.2 is a somewhat exaggerated view of a three ply container wall.

Fig. 3 is a section. on the line 3 -3 of Fig. 2 and container, and

' Fig. '4 1s a modified cross section showing a modified butt joint.

' The container shown in Figs. 1, 2 and 3 com rises the tapered wall which is general- 1y cesi nated by W and the bottom B inserted therein. It may be closed or sealed by a cap, cover or lid L. Y

V The wall member as shown in Figs. 2 and 3 is a ply structure comprising an outer member W, an inner member'W and in'Fig. 2

an interposed member W". This member IV is preferably of more porous stock and preferably is coated with glue or other adiesiveon both faces. In some cases, it may be .actually impregnated and can be made to add various factors to the wall structure as, for example, to introduce a stiffening resultant due to its impregnation.

The external and internal sheets W and W may be of any desired character and may be of different stock or of; stock difierently processed. The internal-member W may be w aterproofed if extra impermeability is desired and the external sheet may be of fancy colored or embossed stock or may be printed prior to assembly if desired.

The number of the wall members may be varied as desired from a simple pair cemented face to face to larger members which may be paired In most cases, the bottom member B is formed of simple sheet stock, but it may be composite throughout or centrally reinforced.

In the production of my containers, I provide die membersnot shown. Considered in its simplest form, my method consists in first inserting into the die the outside blank W. In the insertion, the blank is brought roughly to shape and deposited within the die in which it fits exactly with its edges closely vQ butt jointed.

At thenext step if a two ply canor container is to be formed a second blank W is in-. sorted. If a three ply container is to be formed as shown in Fig. 2 a'wallmember I W is inserted. This member may be of ab.- sorbent stock and coated with adhesive on both faces. The seams S, S and S are staggered with reference to each other.

Another factor advantageous to fine con- 'tainer making arises from the possibility of shrinking the outer member to the inner member or members, is that in this phase of my invention, I form the member to be shrunk by cutting it with its peripheral dimension I transverse to the grain'or run of the paper. By a selection of stock with reference to its expansibility with water or wet adhesive applied to the inner face of the outer wall member I can get inner or outer or intermediate I or otherwise assembled in groups. 1|

members that will shrink on drying or will give no shrinkage or relatively so much less shrinkage that I am able to make one member squeeze to another.

In containers of standard measure size the j 5 importance of providing for a filling to-the top level thereof is important. In tapered wall containers it is dificult to get a tight seal if a lap seam or other irregularity is present.

may be given any degree of stiffness desired or any of a great variety of finishes. When reduced according to my method, they can e manufactured at reasonable cost and in" quantity production.

The seams of the side walls of my container as shown are straight .line seaming but the wall edges may be interrupted as at S as shown in Fig. 4. In this a wall W is shown with dovetail projections and recesses. The edges may also be skived or tapered to get a flat seam. The bottom B is shown as a simple inserted member but it may be of any form and assembled in any desired manner. As'indicated the container may be of tapered wall type or of cylindrical type as shown in Fi 4. a

In claiming my invention, I desire to indicate a reasonable scope of my invention which I believe is fairly represented by its defini tion in the following claims. What I therefore claim and desire to secure by Letters Patent 1. In a container of the class described, a side wall comprising a plurality of wall members having edge abutted joints, said joints being in non-registering relation to each other, each wall hav-in the grain of its paper 5 disposed differently t an the grain of the paper of the other Wallswhereby said walls have different degrees of shrinkability when wet and drying, a stifiening adhesive material between said walls, a bottom member havin a downturned flan e lying parallel to sai Walls, and a closure havin a resilient downturned flange adapted to e wedged within the open end of said container wall.

2 In a container of the class described,

a side wallcomprising a plurality of tapered wall members having edge abutted joints, the

innermost of said 'wall members havingbea crenelatied edge-abutted joint, said joints mg in non-reg1stering relation to each other,

' each Wall having the grainof its paper dis-- 1, posed differently than the grain oi the paper of the other walls whereby said walls have different degrees of shrinkability when wet and drying, a reinforcing member between '6 said walls impregnated with an adhesive Inaterial, and a bottom member united within said inner wall.

3. In a container of the class described, a Y

' side wall comprising a plurality of wall members having edge abutted joints, said inner wall member having a crenelated edge abutted joint, said joints being in non-registering relation to each other, each Wall having, the grain of its paper disposed differently than the grain of the paper of the other walls whereby said walls have different degrees of shrinkability when wet and drying, a stiffening adhesive material between said walls, and a closure having a resilient downturned flange adapted to be wedged within'the open end of said container wall. j

In testimony whereof I aflix my signature.
