Abstract

Abstract A liquid container comprising a cup, the contents of which have a more or less low viscous consistency, which is closed by a lid. Radially inwardly of the pouring edge of the cup the lid has a recess which comprises a bottom and an annular side wall, said side wall being spaced from the inside surface of the cup so as to present around a portion of its circumference a slot-like interspace between the inside surface of the cup and the annular side wall. The volume of liquid contained in the cup is such that the liquid, when the cup stands vertical, fills the whole of the cup below the bottom of the recess and fills at least a portion of the slot-like interspace.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 261 words
A disposable type container structure for liquids of low viscous consistency comprising: a cup having a tapered side wall configuration of annular crosssection; the smaller diameter end terminating in a bottom wall joined to said annular side wall; the larger diameter end having an outwardly extending annular shaped pouring lip; a lid for sealing the open larger diameter end of said cup; said lid having a tapered side wall configuration of annular cross-section; the small diameter end of said lid side wall having a bottom wall integrally joined to said side wall; the larger diameter end of said lid side wall having an outwardly extending lip; an inner portion of said lid lip extending below the free end of said lip and resting on said pouring lip to define an annular space between said lips; the tapers of said cup and said lid being similar whereby the adjacent side wall sections of said cup and said lip are substantially equally spaced from one another to define a narrow slot-like interspace between the inner surface of said cup side wall and the outer surface of said lid side wall; the spacing between the lip of said cup and said lid side wall and between the bottom end of said lid side wall and said cup side wall being substantially equal; said cup being filled with said liquid to a level above the bottom wall of said lid so that said liquid fills at least a portion of said slot-like interspace to minimize the exposed area of the top surface of said liquid.
Claim 2
Dependent Claim 261 words
A disposable type container structure for liquids of low viscous consistency comprising: a cup having a tapered side wall configuration of annular crosssection; the smaller diameter end terminating in a bottom wall joined to said annular side wall; the larger diameter end having an outwardly extending annular shaped pouring lip; a lid for sealing the open larger diameter end of said cup; said lid having a tapered side wall configuration of annular cross-section; the small diameter end of said lid side wall having a bottom wall integrally joined to said side wall; the larger diameter end of said lid side wall having an outwardly extending lip; an inner portion of said lid lip extending below the free end of said lip and resting on said pouring lip to define an annular space between said lips; the tapers of said cup and said lid being similar whereby the adjacent side wall sections of said cup and said lip are substantially equally spaced from one another to define a narrow slot-like interspace between the inner surface of said cup side wall and the outer surface of said lid side wall; the spacing between the lip of said cup and said lid side wall and between the bottom end of said lid side wall and said cup side wall being substantially equal; said cup being filled with said liquid to a level above the bottom wall of said lid so that said liquid fills at least a portion of said slot-like interspace to minimize the exposed area of the top surface of said liquid.
Claim 3
Dependent Claim 55 words
A container according to claim 1, characterIzed in that the annular side wall of said lid is provided on the outer surface thereof with a plurality of radial shoulders adapted to center the lid recess in the container so that the slot-like recess has approximately the same radial width around the circumference of the cup.
Claim 4
Dependent Claim 164 words
A container according to claim 1, on which cup lip a corresponding portion of the lid is secured by joining together the mutually abutting surface of the lip and the lid, characterized in that the edge portion of the lid includes a radial edge flange whose radial outermost portion is axially spaced from the lip of the cup at a distance of at least 2 mm therefrom to enable a coin to be inserted between said portion and the lip for the purpose of removing the lid, and that the aforesaid inner portion of the lip of said lid is provided with an annular groove, the bottom of which abuts the lip of the cup and is affixed thereto by means of a weld which can be broken by twisting said coin, one side of the groove merging with the edge flange of the lid and the other side of said groove merging with the upper portion of the side wall of the recess.
