' HENRY SCHNACKENBERG, OF CRESCO, PENNSYLVANIA DRINKING CUP.

Application med September 10, 1921. Serial mi, 499,619.

To all'whom itm'ay concern: Be it known that I, HENRY SGHNAOKEN- BERG, a citizen of the United States, and a residentof Cresco, in the county of Monroe and State of Pennsylvania, have invented a new and Improved Drinking Cup, of which the following is a description.

My invention relates to paper drinking cups and more particularly to a drinking cup in which the bottom isformedby overlapped. tongues integral with'the cup and bent into position to form a closure of the cup at the bottom.

The general object offmy invention is to provide a cup of the indicated character improved in various particulars to the end that the cup will be reinforced atthe bottom, the cup being further characterizedby a novel arrangement of thetongues constitutingthe bottom.

Reference is to be had to the accompany-- ing drawing: forming a part of this specification, it ings are merel illustrative of practical examples of the invention.

Figure 1 is a vertical section of a drinking cup formed in accordance with my invention, as indicated-by the line 1--1, Figure 2; r v

Figure 2 is a horizontaljsection on the line 22, Figure 1;

Figure 3 is a planview of the blank that may be utilized for forming the cup and in which the slits dividing thetongues are 7 body so that the reinforce flares upwardly carried through the reinforcing zone;

Figure 4 is a vertical section of the lower portion of the cup, the cup having the bot-- tom slightly modified as referred'to hereinafter;

Figure 5 is a fragmentary view showing a portion of. the blank and modified so that tice of-wax paper as is usual in the trade and in'practice the blank, as shown in Figures 3 and 4, from which the cup body is formed is made with a flange 11 at one side terminating short of the bottom of the blank and adapted to overlap the opposite ed e when the blank is bent to form a round b y. The bottom designated generally-by the numeral 12 is elevated above the lower edge of the body so thatlthe latter has an' ing understoodthat the draw-v annular sustaining bottom edge 13 below the bottom.

The bottom 12 is formed of tongues 14 I 'to a point 15, said point being formed at the juncture of two adjacent tongues and pronounccdly nearer to one side edge of the blank than to the other; The edge formed jointly by the tongue ends presenting a long curve 16 and a short curve 16*. The purpose of the described arrangement of the tongues isto produce an approximate uniformity throughout the bottom.12 and prevent ac-' cumulated material at the center by reason of too great a plurality ofoverlapping tongue parts.

In association with the bottom as described, I form the blank 10 with a reinforcing zone 17 scored on two lines 18, 18 The slits 19 separating'the tongues may extend through the reinforcing zone 17 as in Figure 3 or as shown in Figure 5 the slits 19) may terminate at the reinforcing zone 17*) making said zone unslitted. In forming the cup from the blank the latter is in correspondence with the body. In Figure 4 I have shown the modified arrangement in which the upturned zone 17 is turned up in cylindrical form so as to be spaced from the flaring body 10 of the cup therebyleaving an annular channel between the reinforcing zone and the body into which the wax may run in the coating of a the cup.

In practice the tongues 14 are caused to adhere to' each other by the application thereto of a suitable adhesive materiafwhich reduces the tongues to a limp condition whereupon b the pressure of a mandrel, the tongues are attened out into a single plane to form in effect a omogeneous bottom.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein an annular channel therebetween for receiving Wax.

2. A drinking cup formed of a blank and having the bottom formed of a plurality of tongues integral with the body and overlapping to form a. closure of the cup, said tongues bein of increasing length from the side edges ot the cup to a point nearer one side edge than the other.

3. A drinking cup formed of a blank and having the bottom formed of a plurality of tongues integral with the body and overlapping to form a closure of the cup. said tongues being of increasing length from the side edges of the cup to a point nearer one side edge than' the other, the ends of the said tongues increasing slightl from a side edge of the body oithe-cup toward the opposite edge, the increase in tongues jointly presenting curves terminating at said point.

4:. A drinking cup having the bottom formed with a plurality of tongues overlapping and forming a closure of the cup, in length length being more abrupt toward a point short of the opposite side edge.

5. A drinking cup having the bottom formed with a plurality of tongues overlapping and forming a closure of the cup, said tongues increasing slightly in length from i a- 'side edge ofthe' body of the cup'toward the opposite edge, the increase in length being more abrupt toward a point short of the opposite side edge, and those tongues between the said point and the opposite side edge decreasing in length toward said opposite edge.

(5. A drinking qup having a bottom formed with a plurality of tongues overlapping and forming a closure of the cup, said tongues increasing in length from a side edge of the bodyot' the cup to a point short of the opposite edge, the end edges of the tongue bein on a curved line.
