PAPER CONTAINER Filed June 4, 1931 INVENTO W ATTORNEYS Patented July 18, 1933 UNITED STATES PATENT OFFICE ERNEST HUFF, OF MILWAUKEE, WISCONSIN, ASSIGNOB. TO AMERICAN LACE PAPER COMPANY, OF -MILWAUKEE, WISCONSIN, A. CORPORATION OF WISCONSIN PAPER CONTAINER I Application flled lune 4, 1931. Serial No. 542,071.

This invention relates to improvements in paper containers.

It is the purpose of the present application to provide an effective and novel rein- 5 forcement for the mouth of a container made of paper or other light sheet material. It is proposed to compact the multi-folded margin of a cup or container back upon the body portion thereof in the form of a band bead of such form and solidity that the margin will be confined within the band. A band bead made in accordance with this invention will have no interior hollow and will lie in approximately cylindrical form about the upper ortion of the wall-of the container to reinorce the mouth of the container very strongly against distortion and to hold the pleats, if any.

In the drawings:

Figure 1 is a perspective view of a completed container embodying this invention.

Figure 2 is a diagrammatic fragmentary cross section showin an enlarged detail of the fold embodying e present invention.

Like parts are identified by the-same reference characters throughout the several views.

The body ortion 3 of the cup is preferably, althoug not necessarily, pleated. The margin 4 is then folded not merely once, or twice, but at least three times back upon itself to form band plies 5, 6, and 7 which are disposed in face contact and are forced against the upper or mouth portion 8 of the cup wall under pressure sullicient to give them a more or less permanent set in the position indicated in 2.

During the application of pressure the inner ply 6 will actually be in face contact with the cup wall, and the only resilience reoperation will bring the band bead only sufliciently far away from the wall of the cup to maining in the paper following the pressure and such resistance is augmented by the friction or resistance between plies which, being in face contact, function very differently from the manner in which they would if they were not so compacted.

It is further to be noted that the extreme margin 4 of the paper is confined between the two plies 6 and 7 of the band bead which are joined by a fold at 9 so creased under pressure as to resist the enlargement of periphery which would be occasioned by any outward swinging movement whatsoever.

For the foregoing reasons it will be obvious that the band bead herein disclosed functions in a novel way to attain most satisfactory results in the way of reinforcement of the mouth of a paper container. It will, of course, be understood that the cross sectional view of the bead in Fig. 2 is somewhat distorted due to the im ossibility of showing. the head as compact y pressed against the wall of the cup as is actually possible where paper is employed.

claim:

A pleated paper container havin a pleated tapered wall and an integral band ad comprising three plies of the material of the con tainer successively folded back upon said wall with the end ply extending downwardly between the other two lies the outer ply being substantiall c lin rical and forming an acute angle wi t wall of the container, the extreme margin of the material comprising the container being embraced by the lower margins of the two plies connected together about said extreme margin and held thereabout by contact of the innermost ply with the wall of the container whereby to opthe opening of the head, said bead serving to hold the pleats in position, the innermost pair of plies nesting in the angle between the cylindrical outer ply of the bead and the tapered wall of the container.
