Abstract

Abstract A disposable cup with integral straw situated at a lap joint of the cup such that the infirmed, infants and others desiring to elevate liquid from the cup into their mouth may do so using the seam straw without materially tipping the cup. The cup is preferably designed so that it will be economical and will nest with other cups whereby the seam straw is partially or completely though resiliently collapsed in such a fashion as to permit it to return at least in part to its original orientation adequate to permit fluid flow therethrough.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 252 words
A disposable drinking cup, which may be nested with one or more cups of the same construction, comprising: a generally vertically directed thin wall of impervious sheet material having opposed overlapping end wall areas defining a lap joint extending along essentially the entire height of the wall; upper edge means disposed at the top of the wall, the upper edge means defining a top opening to the cup of a first diameter; a thin bottom wall of impervious sheet material filling the space between and being integral with the generally vertical wall at the bottom edge thereof, the diameter of said space being less than said first diameter; the opposed overlapping end wall areas of said lap joint being overlapped one in respect to the other with the extreme end of each being flatly secured to the opposite wall area, each wall area having essentially the same height as the other and at least one having a substantially greater circumferential dimension than the straight line distance between the flatly secured ends, the at least one wall area having the greater circumferential dimension extending radially away from said straight line distance to from an unencumbered hollow passageway between the unattached wall areas adjacent the flatly secured ends thereof, said passageway comprising an open unobstructed liquid effluent port adjacent the upper edge of the cup; the wall area comprising the passageway which is exposed to the interior of the cup comprising an open unobstructed liquid inffluent port adjacent the bottom wall of the cup.
Claim 2
Dependent Claim 252 words

Claim 3
Dependent Claim 29 words
A disposable drinking cup in accordance with claim 1 wherein only one wall area has the greater circumferential dimension and is disposed radially inwardly of the other wall area.
Claim 4
Dependent Claim 27 words
A disposable drinking cup according to claim 1 wherein only one wall area has the greater circumferential dimension and is radially outward of the other wall area.
Claim 5
Dependent Claim 30 words
A disposable drinking cup in accordance with claim 1 wherein the at least one wall area having the greater circumferential dimension is collapsible to accommodate said nesting of said cups.
