DRINKING-CUP.

1,oov,91s.

Specification of Letters Ilatent.

Application filed June 21, 1910. Serial No. 568,238.

To all whom it may concern:

Be it known that I, HARRY H. CHAMBERS, a citizen of the United States of America, residing at Fort Collins, in the county of Larimer and State of Colorado, have in-- vented certain new and useful Improvements; in Drinking-Cups, of which the following is; a specification.

his invention relates to improvements in drinking cups and its object resides in thel provision of a collapsible cup which may be. carried either singly or in detachable con-l nection with other similar cups and whichl' after having been filled and emptied once, is unsuited for. further use.

An embodiment of my invention is illustrated in the accompanying drawings in the various views of which like parts are similarly designated and in which Figure 1, represents a plurality of the improved cups formed in sheets which are bound in book form, Fig. 2, a face 'view of one of the detached sheets, Fig. 8, a perspective view of one of the cups opened for use, Fig. 4: a section taken along the line 4-4 Fig. 2, and Fig. 5, a section along the line 55 Fig. 2.

Referring to the drawings, the reference character 2 designates the improved cup which is composed of two preferably rectangular, normally flat pieces 3 of paper or other similar material which are joined along three of their edges 4, by the use of an adhesive or other suitable means. The pieces 3 are at the ends 5 at which they are disconnected, preferably doubled as shown in the drawings, to provide a firm and blunt edge to be presented to the lips of the user.

Formed in the side edges of the cup near its mouth, are notches e to form a finger hold when separating the sides of the cup as shown in Fig. 3.

The cups are preferably produced in sets of four, as shown in Fig. 2 of the drawings, by doubling two rectangular sheets of paper 8 along opposite edges and connecting them along their other edges and at opposite sides of two central intersecting lines 7 which-are either perforated or weakened to permit the user to readily and separately detach each cup from the others. A} number of the sheets may be gummed together at corlrespojnding edges to form a pad oria book as shown in Fig. 1, from which the cups may be stripped as they are used and which provides a convenient medium for carrying them in? a trunk or other case. By folding the cups upon each other along the intermediate lines 7, a considerable number of them may be carried in the pocket of a garment.

.The material of which the cups are made, is absorbent to a degree which prevents their being filled and emptied more than one time, after which they are useless and must necessarily be discarded, and if so desired, the

adhesive attheir closed edges may be of such a character that it will dissolve or soften after having been subject to moisture for a short period.

The cups, before being placed on the market, are thoroughly sterilizedand inasmuch as they can be used but one time as herein above explained, it will-be readily seen that the danger of contamination or contagion present whenever a drinking vessel is used by more than one person, is entirely avoided.

Having thus described my invention which I claim and desire to secure by Letters- Patentis:-

As a new article of manufacture, aplurality of drinkin cups formed conjointly of two rectangulan fl rial of equal size, covering one another and pasted together along their opposite side edges and along portions extending at opposite sides of two intersecting weakened lines disposed respectively mediately of the side edges and of the end edges of the saidsheets at sheets of flexible matein substantially parallel relation thereto, the
