Abstract

Abstract A drinking cup of impregnated paper or similar material in which the side wall element includes additional material at one vertical edge thereof which is folded upon itself to form a drinking straw extending from the bottom of the interior of the cup to a level above the upper rim of the cup. The straw is foldable within a slot in the cup when not in use to enable the cup to be closed by a lid. The lid is provided with an opening which permits the straw to be erected to operative condition and the contents of the cup consumed without removing the lid.

Claim 1
Independent Claim 256 words
An improved cup construction for soft drinks and similar comestibles comprising: a frusto-conical side wall including an upper beaded edge and a lower crimped edge, a planar bottom wall sealed within said lower crimped edge to form a liquid container; said side wall being formed from a planar blank of flexible material having inner and outer surfaces, an upper edge and a lower edge, a free side edge and a fold line extending between said upper and lower edges; an integral straw element extending outwardly of said fold line of generally rectangular configuration, said straw element extending upwardly of said upper edge and downwardly to the area of said lower wall, said straw element being longitudinally foldable upon itself to form a channel for the passage of liquid from the interior of said container; said straw element being bounded by a free longitudinal edge and said fold line and being interconnected together in the area of said free longitudinal edge and said fold line to enclose said channel; said blank being interconnected in the area of said first mentioned free edge and said fold edge to enclose said straw element; said straw element having a transversely extending fold line to enable the folding of said straw at said upper edge of said container, wherein the part of the straw element disposed thereabove may be positioned alongside the outer surface of said container; said upper edge of said container having a recess to accommodate said transversely extending fold line and enable the positioning of a cover thereupon.
