DRINKING-CUP.

Specification of Beissued Letters Patent. Reisgued May 20, 1919.

Original No. 1,148,149, dated July 27, 1916, Serial No. 829,488, filed April 4, 1914. Application for reissue l filed October 16, 1916. Serial No. 126,056.

To all whom it may concern:

citizen of the United States, residing at Kens sin n, in the county of Hartford and State of onnecticut, have invented a new and Improved Drinking-Cup, of which the followin is a specification.

y invention relates more especially to that class of drinking cups that are made from paper or other 11 ht materlal and that are intended for indiv1dual use, and an object of my invention, among others, is to provide a cup of this class with its lip thickened to provide suflicient rigidity to resist collapse under weight of the contents.

One form of cup embo ying my invention, and in the construction and use of which the objects herein set out, as well as others, may

be attained, is illustrated in the accompanying drawings, in which igure 1 1s a view in elevation of one s1de of a cup embodying my invention.

Fig. 2 is a view of the opposite side of the Fig. 3 is a view in len hwise section on plane denoted by dotted line 3-3 of Fig. l, the cup being shown as partiall o ened to illustrate its form when in use or rinking purposes, the thickness of the material being exgggerated.

1g. 4 is a view in section on plane denoted by dotted line 44 of Fig. 1, the cup having the same form as in Fig. 3 and the thickness of the material being exaggerated.

Fi 5 is a detail view il ustratmg the blan from which my improved cup is formed.

My invention appertains to the class of sanitary drinking cups composed of paper or other thin material folded to provide a flat structure, but the back and front walls of which are separate, especially at the top, when required for drinking purposes. eretofore the lips or drinking ed s of the cups 'have been mmposed of a sing e piece of thin material, as paper, with insutlicient rigidity to resist collapse from the weight of the contents, with a result that such contents are I liable to be spilled upon the person using the cup, and this single thickness also presenting a sharp edge liable to cut the flesh. My improved cup is constructed to overcome these objections and the lip or drinking edge vis sufficiently stiff to resist the wei ht of the Be it known that I, HENRY B. Coomr, a-

contents and prevent collapse, suc cu being illustrated in the accompanying rawings, in which the numeral 5 indicates what I term the front flap of the cup, this being the flap, the upper or drinking edge of which is presented to the lips in drinking, and the numeral 6 denotes the back flap. These two flaps are preferably formed of a single piece of matenal folded at the bottom manner, in a preferred form and as shown herein this being overturned from the flap 5. In order to increase the rigidity of this stiffening piece 10, by preventing a cree ing movement crosswise o the cup, this sti ening piece at its ends is located underneath the folds 9 and securely fastened thereunder. In the preferred form of construction both sides of the stiffening piece are provided with an adhesive at the oints overlaid by the folds 9 so that the sti ening piece at this point is secured firmly against the outer surface of the front flap 5 and the folds 9 are securely held against the outer surface of the stifi'ening piece. Preferably the entireunder surface of the latter is provided with an adhesive so that it is securely fastened against the outer surface of the fla 5. In order to provide the greatest rigidity at the point of greatest strain the lip 10 is gradually widened from its ends to the center, at which latter point the greatest pressure occurs.

A cup constructed as above described is found to possess all of the requirements for the use to which the cup is intended to be put, and the upper or drinking edge is sufficiently rigid to satisfactorily fulfil all of the functions required of it. Itis to be understood, however, that the cup need not be constructed exactly as illustrated and deminimum pressure upon its ed of the user, while its flaring edges, stiffened by the side flaps, act as levers for readllyforcing the mouth of the cup open, these levers pivoting as it were, upon the corners bottom of the cup. The tapered fOrm of the cup also locates the T118001 portion vof the water in the cup, relatively high thereimand therefore "near the mouth thereof, so as to secure the greatest convenience in drinking the water from the cup with the The protection of the drinkmg edge y its forma tion with a flap is also important as without such a flap the mouth is apt'to be cut.

Without cutting down the complementary edge of the cup, to form a clearance space, the cup cannot conveniently be tilted over the upper lip and nose in drinking from it.

- .My lnvention is especially intended to enable the production of acompact, convenient, safe, and comparatively inexpensive cup of the kind that are distributed free, and an important feature, among others, is

such a cup constructed of thin material. Such thln paper cups having parallel sides require such pressure to retain them with their heavy contents in the hand, that the are readily collapsed, and my improved cups havin the tapered edges, therefore, serve a use '1 purpose as they enable such a cup to be easily supported by the hand against the tapered sides and without a grasp suflicient to collapse the cup, My improved cup combines all of these features in' one cup and thus becomes superior to the flat drinking cups of the prior art, none of which have the same convenience and efli: ciency. l I

I claim 1 1. A. drinking cu consisting of 'a front and back flap, a sti ening piece ov t d onthe outside of one of said flaps at the upper edge thereof and extending thereacross, and means overlapping each end of said stiffening piece to secure it in place.

2. A drinking cup including a front and back flap, lengthwise folds for securing said flaps together, and a stiffening piece secured to the drinking edge of the cup and with its ends underlying-said flaps and secured in place thereby. I

3. A drinking cup composed of a front and a back flap, lengthwise folds for securing said flaps together, and a stifiening piece overturned on the outside of the drinking edge of said cup and extending underneath said folds and provided with an' adhesive on its opposite sides to secure it to the flap and to secure the lengthwise folds thereto.

4. A drinking cup consisting of a front and'back fla a stiifening piece secured to the upper e ge of one of said flaps and gradua ly increasing in width from its ends, to its center, and'folds at theedges of the cup engaging said stifl'ening piece to secure it in place.

5. A drinking cup inc and a back flap, the latter being folded lengthwise at its edges onto the front face of the front flap, and astiifening piece folded over from the upper edge of the front flap and having its ends underlying and secured by the folded edges of the back flap.

6Q As a new article of manufacture, a flat paper drinking on formed from a relatively longblank fo ded transversely to prodlice two flat complementary body-flapstogether forming a cup-bod which is closed at its bottom end" by sai transverse fold,

one of the said body-flaps being formed at its outer end with a supplemental fla arranged at a right angleto the axis e f the cup and folded transversely thereto upon one face of the said body-flap to produce a smooth drinking edge for the cup, one of HENRY B. .COQLEY.
