COLLAPSIIBLE DRINKING-CUP.

Specification of Letters Patent.

Patented May '7, 1912.

Application filed September 25, 1911. Serial No. 651,087.

To all whom it may concern:

Be it known that I, SAMUEL CURTIS, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Collapsible Drinking-Cup, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Heretofore, collapsible drinking cups have usually been of the telescoping type in which the body or cup proper is formed of a plurality of metallic rings telescoping one within another. One objection to cups of this type is their weight and bulk, and another objection is that the telescoping rings are very liable to become injured so that they will fail to make a water tight joint, and the cup thus becomes useless.

The object of my invention is to provide a collapsible drinking cup in which the objectionable features referred to will be overcome. This I accomplish by forming the body or cup proper of collapsible water proof material such as thin sheet rubber,

and providing means for supporting the cup in its extended position, as will be fully pointed out hereinafter.

In the accompanying drawings, which illustrate one form of cup made in accordance with my invention, Figure 1 is a vertical central section; Fig. 2 is a side elevation; Fig. 3 is a top plan view, the body of the cup being folded but the lid being in raised position, and Fig. 4 is a side eleva tion of the cup in its folded or collapsed position.

Like numerals of reference refer to similar parts in the several views of the drawings.

5 is the body or cup proper. This body is formed of flexible water proof material, preferably thin sheet rubber. The bottom of the body 5 is secured to a base 6 by having its edges clamped between said base a disk 7 corresponding in size to the bottom of the body. This disk 7 may be secured to the base 6 in any suitable manner. In the drawings, I have shown a screw 8 for securing these parts together. The upper end of the body 5 carries a supporting ring 9 from which projects an H-shaped member 10 for supporting the top of the body from the lid, as will be hereinafter described. The base 6 is provided atdiametrically opposite points with a pair of enlargements 11 and 12, respectively, each forming receptacles. Within the receptacle 11 is a coil spring 13 which surrounds a rod 14 which serves as a pivot to hinge the lid 15 to the base 6. This lid 15 corresponds in shape with the base 6 and is provided with a slot 16 adapted to receive the H-shaped projection 10 hereinbefore referred to, when the cup is in its extended position. In order to fold the cup the projection 10 is disengaged from the slot 16 and the supporting ring 10 is rotated through one-half a revolution to twist and fold the body 5 so that the body will collapse within the base 6 and the projection 10 will come within the receptacle 12, as shown in Fig. 8. The lid is then folded down and held in its closed position by means of a spring detent 17, as shown in Fig. 4.

It will be evident that my cup is very light and compact in construction, and that there is practically no liability of the body or cup proper becoming injured so as to allow leakage.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1. In a collapsible cup, the combination with a body of flexible material, of a base to which the bottom of said body is secured, and a lid for said base adapted to support the top of said body.

2. In a collapsible cup, the combination with a body of flexible material, of a base to which the bottom of said cup is secured, and a pivoted lid for said base adapted to support the top of said oody.

3. In a flexible cup, the combination with a body of flexible material, of a base to which the bottom of said body is secured, a supporting ring carried by the upper end of said body, a lid pivoted to said base, and means for detachably securing said lid to said supporting rin 4. In a collapsible cup, the combination with a body of flexible material, of a base to which the bottom of said body is secured said base having enlargements forming receptacles at diametrically opposite points, a lid pivoted to said base, a spring in one of said receptacles for moving said lid into a position substantially at right angles to the base, a supporting ring carried by the my hand and aifixed lny seal in the presence upper end of said body, and a pro ection of the two subserlblng Witnesses.

carried by said rin and adapted to en a 'e V with said lid said projection being adapt d SAMUEL GURFIIS' to enter the other of said receptacles When Witnesses: the body is rotated to fold the same. W. A. ALEXANDER,

In testimony whereof, I have hereunto set B. L. CROWLEY.
