To all whom it mag concern; a

Be it knownthat I, PAUL H. CAGRR, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful limprovements in Collapsible Drinking-Cups, of which the following is a specification.

@wing to State and municipal sanitary regulations, extensive. Some of the cups m use are 'molded in permanent extended position,

while the large majority of cups in use are made in the form of collapsible cups. Objection has been found to the collapsible cup in that it is practically impossible to extend the cup for use without inserting thefinger l or some device to open the cup. This is frequently inconvenient when a person has a bundle in one hand. Again the collapsible cup now in extensive use is objectionable in that it does not open up symmetrically and frequently buckles, wheneby it is awkward to. drink from said cup.

- to extended The object of my invention is to provide a collapsible position for use by simply press- 1ng inwardly upon two opposite walls of the cup, thereby eliminating the necessity of using two hands to open the cup; with these and other objects in view my invention consists of the parts and combination of parts as will behereinafter pointed out.

In the drawing Figure 1 is a perspective view of a collapsible cup in extended position, embody- 111g my invention.

Fig. 2 is a front elevation of my improved collapsible cup in collapsed position.

Fig. 3' is a bottom plan view of my improved cup shown in extended position.

Fig. 4 is a view showing the position of the wallsof the cup after .the side walls have been pressed slightly inward.

6 and 7 extending vertically thereof and parallel with the line of juncture-between the side and the front and rear walls, the. score 6 being formed to permit the major portion of the side wall to fold outwardly while the score 7 is such as to permit the the use of paper cups is quite' paper cup which may be opened ture between the side and together thereby pr entin .and 9 extending from the juncture of the scores 6 and '7 to the lower corners-of the cup as clearly shown in Fig.1, said scores 8 and 9 cooperating with the score 7 to permit. the inward folding of the lower portion of the side walls as shown in Fig. 4.

The bottom wall 5 is scored along the line 10 to permit of the inwardly folding of the bottom wall as clearly shown in Fig. 4;, the score 10 being in alinement with the score 7. The bottbm wall, as shown 'in Fig. 3, is dished at its ends and lines 11 for an inward fold and scored along the lines 12 at the walls for an outward fold so that there is a triangular portion in the bottom wall between the

scorings

11 and 12 as clearly shown in Fig. 3.

As will be seen from "Fig. 5 the cup at the juncture of the vertical walls is scored as at 13 to facilitate the extension of the walls to extended position to insure a straight fold at the juncture of the walls.

As will be seen from the drawing the cup is adapted to be collapsed and when in collapsed position the two side walls, or two oppositely disposed walls, of a cup, are folded outwardly beyond the line of juncfront and rear walls, whereby inward pressure upon the outwardly folded walls, in the manner illustrated in Fig. 4 will move said side walls to extended position, and when the side walls are moved to extended position they force the front and rear walls apart and thus move all of the walls of the cup, including the bottom wall, and open the pup for use.

What I claim' is:

1. A collapsible drinking cup having integral bottom, and side, front and rear,walls extending therefrom, certain of said walls being overlapped and adhesively secured a cup having side walls of a sub tantia y single thick ness when folded together, saidfiside walls being folded outwardly and the bottom wall folded inwardly when in collapsed position juncture with the side scored along the I to extended position whereby the front and rear walls may lie in intimate contact throughout their major area, a score for an inward fold in the bot tom wall, a score in the side walls, a portion of which is for an outward fold and a portion for an inward fold, all of said scores always lying in the same plane whereby the front and rear walls, above the inward fold of the bottom wall, are free to be in intimate contact with each other throughout their area, whereby inward pressure upon the outwardly folded side walls will move all of the walls of the cup to extended position and thus open the cup ready for use.

2. A collapsible drinking cup the side walls of which are scored vertically whereby they will fold outwardly beyond the body lines of the cup when collapsed, the lower end portion of said side walls being scored in line with the first named score but folded inwardly when in collapsed position, scores extending from the juncture of the two above mentioned scores in the side walls to opposite corners at the bottom of the cup and a score extending centrally across the bottom Wall of the cup from side wall to side Wall and a score in the bottom wall extending from each corner of the bottom Wall and intersecting the said central score of said bottom wall.

In testimony whereof I aflix my signature.
