PAPER CUP Filed Jan. 2l. 1939 Patented Dec. 31, 1940 UNITED STATES PATENT ori-ICE PAPER CUP Ralph V. Nyman, Providence, R. i.
Application January 2l., 1939, Serial No. 252,187
3 Claims. (C1. 22S-5.5)
This invention relates to paper cups and has relation more particularly to a device of this kind especially designed and adapted for use in the dispensing of hot liquids, such as coffee, and it is an object of the invention to provide a cup of a single wrap and wherein the construction of the cup is such as to assure the same being leakproof at the bottom and also at the applied lid or cover.
It is also an object of the invention to provide a cup of this kind wherein the side wall of the body of the cup is formed of a single wrap of paper of desired weight with the endv portions of said strip lapping, the inner lapping extremity being thinned out to a knife edge, thus assuring a leak-proof fitting at all points of the bottom side of the cup and also at the applied lid or cover.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved paper cup whereby certain important advantages are attained and the article rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.
The novel features of my invention will hereinafter be definitely claimed.
In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:
Figure 1 is a view in plan of a blank constructed in accordance with my invention and from which the side wall of the body of the cup is formed;
Figure 2 is a vertical sectional view taken through a completed cup constructed in accordance with an embodiment of my invention with the lid or top in place;
Figure 3 is a fragmentary detailed sectional view taken substantially on the line3-3 of Figure 2;
Figure 4 is an enlarged fragmentary detailed sectional view taken substantially on the line 4 4 of Figure 2;
Figure 5 is a detailed sectional view taken substantially on the line 5-5 of Figure 2;
Figure 6 is an enlarged fragmentary view partly in elevation and partly in section of the lower portion of the cup as herein comprised.
As disclosed in the accompanying drawing, my improved cup comprises the side wall W of a single wrap having its lower portion formed to provide a reverted and inwardly positioned flange i. The bottom wall B of the cup is defined by a downwardly or outwardly disposed flange 2 which engages between the lower marginal portion of the 'wall W and the ange i. In the completed cup the upper marginal portion of the wall W is outwardly rolled to provide therearound a rim 3. The wall W inwardly of but closely adjacent to the rolled rim 3 is provided in the completed cup with the rim seat 4 formed by suitably pressing the wall W outwardly to provide a continuous groove to snugly receive the marginal portion of an applied lid or cover L.
As is particularly illustrated in Figure l, the side wall W is formed from a blank of paper stock of desired weight and texture, said blank in plan being arcuate in form and on a radius depending upon the flare or taper of the cup desired. This blank is of a length in excess of the circumference of the nished or assembled wall so that end portions a and b may overlap and be adhesively connected. The end portion a of the blank has its inner face thinned down to provide a knife edge c. The end portion a in the formation of the wall is inwardly disposed with respect to its associateed lapping portion b at the opposite end of the blank so that, as is particularly illustrated in Figure 3, when the lapping portions a and b are adhesively connected the inner face of the completed wall W is substantially smooth and unobstructed. This is of particular importance and advantage as it assures a leak-proof mounting of the bottom wall B as well as aleak-proof setting of the lid. or cover L which is particularly desirable when the completed cup or container is used in the dispensing of hot liquids, such as coiee.
The knife edge portion c of the portion a of the wall B adjacent to the lower marginal edge of the wall is continued by the outstanding but relatively small projections 5 disclosed in the accompanying drawing as two in number. I do not wish, however, to limit myself in this respect as one of such projections can be employed to advantage as can also a number of projections in excess of two as illustrated. It is 'to be noted that these projections 5 are so positioned as to be below the upper marginal portion of the flange l of the wall W and below the body portion of the bottom wall B as is particularly illustrated in the accompanying drawing. These projections 5 are of advantage as they assure a firmer joint or connection between the wall W and the ange 2 of the bottom wall B.
From the foregoing description it is thought to fbe obvious that a paper cup constructeed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and used, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not Wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out'my invention in practice except as hereinafter claimed.
I claim:
1. A paper container Xcomprising a side Wall having end portions overlapping, the inner lapping end portion being thinned out to knife edge at the side thereof opposed yto the outer lapping portion, anda bottom Wall snugly engaged Within the side w\al l, the thinned lapping portion of the side wall being provided at its knife edge with an outstanding projection to facilitate the assembly of the container.
2. A paper container for yhot drinks comprising a side wall having end portions overlapping, the inner lapping end portion being thinned out to a knife edge at the side thereof opposed to the outer lapping portion, the outer lapping end portion of the side wall being of substantially the same thickness throughout, adhesive means interposed between the lapping end portions of the side wall for securing said end portions,y together, and a bottom Wall snugly engaged within the side wall, the bottom portion of the side wall being formed to provide an inwardly disposed reverted flange, the bottom Wall having a marginal ange engaging between the side wall and the reverted flange, the thinned out lapping end portion of the side wall providing a. leak-proof fitting of the bottom Wall within the side wall at the lapping portions of the side Wall.
3. A paper container comprising a side wall having end portions overlapping, the inner lapping end portion being thinned out to a. knife edge at the side thereof .opposed to the outer lap-4 ping portion, a bottom wall snugly engaged within the side Wall, the bottom portion of the side wall being formed to provide an inwardly disposed reverted ange, the bottom wall having av marginal flange engaging between rthe side wall and the reverted flange, and a projection extending from the knife edge of the inner lapping portion of the side wall closely adjacent to the bottom wall.
