DRINKING-CUP.

Application filed November 15, 1909. Serial No. 528.007.

To all whom tt may concern:

Be it known that I, ALFRED R. HUssEY, of Harvard, Worcester county, State 'of lowing is a specitication.` This inventlon relates to drinking cups,

and then thrown away, being thereby especially well adapted for use in public places where sanitary drinking cups are required.

Prior to this invention drinking cups have been made of paper, but in some instances the cost of vmanufacture has been too great tg permit ofthe cups being used once and then thrown'away'; vin other instances the construction has been such that the parts composing it became separated either before or while in use.'

A drinking cup, even of the cheap form herein referred to, mustbe self-supporting when in upright position, 4so that when, placed on a shelf beneath a faucet, fit is not necessary to hold it, hencea cup must have a substantially rigid bottom even though its, upright walll is flexible.

The object of this invention is to improve of. the cup, whereby the cup will be selfsupporting when in upright position, and the parts composing it will not separate, as,v for instance, the bottom will notl fall out, either before or while in use, yet it may be made cheap enough to be used once and then thrown away, thereby adapting it for use as a sanitary drinking cup well suited for public places.

Figure l is a side elevation of a drinking cup embodying this invention, Figs. 2 and 3 are enlarged vertical sections of the bottom portion of the cup, Fig. 4 is a plan view of a blank composing the bottom-piece, Fig. 5 is an enlarged side view of a portion of the shape to be used in the manufacture of the dotted line 6, Fig. 2, Fig. 7 is a plan View of the blank compo-sing a modified forin of bottom-piece, and'Fig. 8 4is an edge-view of the bottom-piece composed of the blank shown in Fig. 7.

a. represents a tubular conical, or it may be cylindrical, body, which is composed of a sheet of paper bent into tubular form and its edges overlapped and glued or otherwise secured together, as at a.

,"lhe bottom piece which I employ consists of a circular flat disk Z) having its margin cut or formed with inter-dental spaces b', arranged at regular distances apart, thereby forming teeth b2. As shown in Figs. 4, and 5 said spaces may be formed with substantially parallel sides, or, as shown in Figs. 7 and 8, may be 'V made V-shaped. When formed with parallel sides the teeth b2 are dovetailed in shape, and when made V- shaped the teeth b2 have parallel sides. Said teeth b2 are then turned down to form a broken or toothed flange extending entirely l around the bottom-piece, care being taken to preserve the interdental spaces. The teeth are bent downward at their junctions with the central part of the disk, so thatv the material at the edge of the central part of the disk between the `teeth extends across the tops'of the interdental spaces. The bottompiece thus constructed, andwith its teeth arranged on its under side, is then forced into the tubular body from the top toward the bottom until the ends ,of the teeth occupy positions flush .with the lower edge of the tubularbody or thereabouts, and when so disposed the tubular body will be pressed outward' slightly to form in it a groove which receives the edge of the bottom-piece, at the junction' of the central portion thereof and toothed tiange, said groove being represented at c and also when so disposed its interdental spaces b are still preserved. The bottom-piece is made of quite sti paper or cardboard and hence is springy, so that its marginal teeth have an inherent tendency to spring outward and thereby closely engage the lower end of the tubular body. The bottom-piece is thus Very securely held inposition byjfriction, yet additional means are provided for securing the bottom-piece in position as well as for sealing the joint between the bottom-piece and the tubular body. The additional means consists of a coating of paraffin-wax or equivalent material applied to the entire external surface of the cup. The paraffin-wax may be melted and applied in the form of spray, after which it congeals and forms a very solid los coating on the cup. It fills, or at least partially 1ls. all the interdental spaces between the marginal teeth on the bottompiece, as shown at d, and `thereby assists in securing the bottom-piece to the body, and particularly serves to resist downward move ment of the bottom-piece by` forming abutments beneath it. so that they are embedded init and are therebysecurely held', and, furthermore, the portions of the central part of the disk which extend across the tops of the interdental spaces are supported by the waX beneath them. v

The completed cup is waterproof; is sufficiently cheap to manufacture to permit of its being used once and then thrown away; it has a flange at the bottom which is very stiff; it has a rigid bottom-piece whereby ity is self-supporting in upright position; and its parts will not become separated before or while being used. u

Obviously the cup may be employed for other than drinking purposes.

I claim:

A drinking-cup consisting of a tubular It also covers the teeth body and a circular disk having a downwardly-extending toothed iange with interdental spaces between the teeth thereof, said disk being arranged at the lower end of said body with the ends of the teeth of the flange thereof flush with said lower end of the body and a coating lof paralin-wax entirely covering the external surfaces of said body and bottoni-piece, which fills the interdental spaces and embeds the teeth, thereby waterprooing and stifening the cup and sealing the joint atthe bottom, and providing abutments in the interdental spaces, beneath tlie edge of the bottom-piece, which assist in securely holding said bottom-piece in posi tion, substantially as described.

In testimony whereof, l have signed my name to this specification, in the presence of twor subscribing witnesses.
