2 Claims. (01. 229 -1 The present invention relates .to paper receptacles, such as cups or similar articles which are customarily used for individually serving liquids, or semi-liquids, and then thrown away.

' Heretofore such cup-like receptacles have been provided either in flat or collapsed form, or in open-mouthed self-extended form. Flat cups, while readily packed and distributed are open to the objections that they must be opened by the.users and are difilcult to use when'full, due to their tendency to, collapse when held too tightly. 0n the other hand, open, self-extended cups, while much easier to hold and use, are more expensive and require the use of special means for dispensing them in nested relation.

According to the presentinvention, there is provided animproved form of cup-like receptacle,

that possesses all the advantages of an openmouthed cup in use, as well as the advantages of a flat cup, as regards packing and distribution. Briefly stated, the invention contemplates the formation of open-mouthed receptacles from fiat blanks so prepared that by an extremely simple operation, each-blank may be converted into a cup, whenever required. The above and other advantageous features of the invention .will hereinafter more fully appear from the following descrlption with reference to the accompanying drawings, in which:'- s

Fig. 1 isa plan view of a prepared receptacle blank embodying the invention.

Fig. 2 is a view illustrating the firststep of converting the blank of Fig. l-into a cup.

Fig. 3 shows the blank ofFig. [converted into an open-mouthed cup, and the manner of holding Fig. 4 is a sectional view through a pack of blanks enclosed in a dispensing carton. A Fig.- 5 illustrates a modified form of blank embodying the invention.

fig. 6 shows the blank of Fig. 5 converted into an open-*m'outhed-cup. a

Fig. 7 shows a holder for receiving and supporting' cup of Fig. 6.

Like reference characters refer to like parts in the diiferent figures.

Referring first to Fig. 1, a bla l is provided which is substantially semi-circ ar in form, with 1 a center of curvature 0 somewh t displaced from' tliestr'aight edge 2 of the bla In the manufacture of the blank I,'a. ban of gumming 3 is applied thereto paralleling and xtending' up to its straight edge 2, with the other edge of. the gu ming 3 preferably defined by scoring l indicated Y by the dot and dash line, extending through the center of curvature 0. The gumming 3 'isof such a character that any portion thereof will adhere to another portion upon non-moistened contact, although the gumming will not adhere of itself to an ungummedsurface. Preferably, the gumming 3 is in' the form of a dispersed rubber solution, or natural or compounded latex, the invention also contemplating the use of other similar dry-sealing adhesives in the form of thermoplastics, such as arcior resins or galyptol's, either alone or in combination with rubber.

When it is desired to convert the blank I into a cup, the blank isheld by the fingers along its gummed edge as indicated in Fig. 2, and the gum 1ming-3 folded at its middle, which foldingmay be expedited by the provision of scoring 5 extending from the center 0 at right-angles to the scoring 4. The blank is then curled to bring opposed portions of the edge '2 into exact register, and pressure is applied to the overlying gummed portions to bring them into close contact, asshown in Fig. 3. As a result of the engagement of the contacted gummed areas under pressure, the blank I is converted into a complete cup-like receptacle characterized by an open-mouthed body of conical form, with a straight fin 6 of double thickness extending'along one sideof the body, whereby the cup may be conveniently held between the thumb and fore finger, as indicated in Fig. 3. Dueto the inherently moisture-resistant gumming 3, the completed cup retains liquid without leaking, and when held by the fiat fin B, it is very easy for'the'user to present the opposite edge of the cup to the lips for drinking, without spilling.

Obviously, the blanks I can be piled fiat and handled in packs without anypdssibility of the gumming 3 on one blank coming into contact with the gumming on the next adjacent blanks. Furthermore, the blanks can be readily removed, individually, from the packs ,for conversion into cups. In Fig. 4, a pack of blanks i is shown enclosed in a suitable carton I, the bottom of which is cut away at 8 to permit the lowermost blank to be withdrawn flatwlse withits gummed edge uppermost, as indicated. This manner of removing a blank insures that the fingers of the user come into contact only with the, gumming 3 and fiwithv portions oFthe opposite side of the blank which form the outside of the completed cup. Therefore, there is no possibility of the inside of the cup becoming contaminated from contact with the fingers before use.

Referring to Figs. 5 and 6, there is shown a modified cup blank 9, which is in the a segment of a circle. I'n the'manuiactur'e of the blank I, the radial edges I'll thereof are'gummed pressure to the engaged gummed at H, with the same type of adhesive which is applied to the blank I, with score lines I! preferably defining the inner edges of the gummed areas.. In converting the blank .9 into a cup, it is seized between the fingers near its apex and then curled to bring the edges I9 into exact register, followed by the application-o1 areas. This results in the formation of a complete cup, which as shown in Fig, 5, provides an\openmouthed conical body, with a fin it extending along one side thereof by which the*cup may readily be held.

The cups of either Fig. 3 .or are particularly adapted for use ,instead oiglasses; wherever 'beverages or semi-1iquid.i'oods are served, by

reason of theiact that the cup blanks are. not

.exposed to contamination and are converted into cups only as. needed. Furthermore, the provision of the Side fins B and 'II' particularly adapts the cups to be used in connection with a rigid holder for supporting the cupsfiin an upright position. Such a holder is shown at I in Fig. 7 as providing a supporting base I! and a slot It in its'wall for receiving the fin i3 01' the cup of Fig. 6. The reception of the fln IS in the slot It prevents the cup from moving in the holder, and the slot l6 can be convenientlyformed in afhandle portion H by, which the holder may be grasped.

From the ioregoing, it is apparent that bythe present invention there is provided an'improved cup-like receptacle that maybe quickly and .1.'A semi-circular,

easily formed from a prepared blank whenever it is desired to use the same. Cups formed in accordance with the invention thus possess all the advantages or open-mouthed cups in use, with the added advantage of being able to pack the blanks in flat form without possibility of contamination, or the necessity of using any special dispensing apparatus. Obviously, the exact forms of the prepared blanks. may be varied to meet the proportions of the receptacles which it is desired to produce, and the resulting receptacles are adapted for a wide variety of uses. Thus, a soda fountain can utilize several iorms or blanks, bzeceptacles formed from the blank of Fig. 1 ing suitable for serving ice cream, while receptacles formed from the blank of Fig. 5 are 'suitble for serving drinks, as-well as for enclosing ice cream cones so that the melting ice cream will not get on the hands.

I claim,

Lflexlble blank for a receptacle '0! the classdesicribed, provided along v .its diametrical edge with a moisture-resistant,

dry-sealing adhesive. V a 2. An open-mouthed receptacle of conical form made from a flat blank having a straight marginal portion thereof coated with a moistureresistant, dry-sealing adhesive, said receptacle providing a tight, waterproof seam in the form of ,a flat fin extending along the conical body of the receptacle from its apex to mouth, and with said fln comprising overlying pressure-engaged portions of the said dry-sealing, adhesivecoatedmargin of the'blank.
