Disposable beverage container

摘要

A disposable beverage cup is provided to be received by a cup holder having a cup engagement means associated with an opening of the cup holder. The beverage cup comprises a base, at least one sidewall extending upwardly from the base to define a cup opening, and at least one projection disposed substantially horizontally on an outer surface of the sidewall a predetermined height above the base, the projection extending a predetermined distance outwardly from the sidewall. The at least one projection is configured to engage with the cup holder cup engagement means to retain the cup in the cup holder such that the cup is twisted a predetermined angle about a longitudinal axis of the cup to release the cup projection from engagement with the cup holder engagement means. In an alternative embodiment, the projection can be replaced by at least one depression disposed substantially horizontally in an outer surface of the sidewall a predetermined height above the base, the depression extending a predetermined distance inwardly from the sidewall so that the at least one depression is configured to engage with the cup holder cup engagement means to retain the cup in the cup holder such that the cup is twisted a predetermined angle about a longitudinal axis of the cup to release the cup depression from engagement with the cup holder engagement means.

主权项

1. A beverage cup having
a planar base, a substantially frusto-conical sidewall extending and widening from said base, terminating in an opening having a rim, and being centred on a longitudinal axis for said cup; wherein said sidewall has corrugations throughout the entirety of said sidewall, from said base to said opening, wherein said corrugations are formed from a plurality of projections and depressions and extend circumferentially around the entirety of said sidewall except where corrugations terminate at said base and said opening, wherein the entire outermost edge of each of the projections of the corrugations lie in a corresponding and different one of a plurality of straight, parallel, and non-intersecting planes that are tilted relative to said longitudinal axis, provided that the tilt is less than 90°, and wherein said corrugations are shaped to engage with a cup holding aperture of a cup holder and to disengage therefrom by twisting said cup about said longitudinal axis and by urging said cup away from said cup holder.
