Stackable stay-cold stein or drinking glass

Abstract

A drinking vessel that has the capability to be stackable and which, by using regular water ice or dry ice, has the ability to maintain a cold temperature for the beverages while not diluting the potency of the liquid or diminishing the quality of the taste. The stackable aspect of the design allows the containers to be nestled within each other allowing for greater quantities of the vessels to be shipped at a single time. A sealable, removable bottom allows for the ice to be secured with the hollow chilling chamber. A handle, which may be formed into the vessel at the time of casting or may be attached after shipping, along with the base that is larger in diameter than the top because to the stacking feature, create the appearance of a traditional beer stein.

Description

BACKGROUND[0001]1. Field[0002]The present invention relates to cold-liquid drinking vessels and more particularly to beer steins.[0003]2. Related Art[0004]In U.S. Pat. No. 4,424,990, White et al disclose thermo-chromic compositions which change color with temperature changes. These compositions are commercially available and are used in thermometers and novelty items, and simply reflect the ambient temperature of the liquids within the vessels. They do nothing to affect the temperatures or to keep the beverage cold.[0005]In U.S. Pat. No. 5,156,283, Sampson teaches that a beer stein should be of suitable material so as to not be conductive of heat and proposes a wooden stein. Further, Sampson teaches that decorative emblems can be embedded in the wood to increase the attractiveness of the drinking container, however this proposal has a limiting effect as to what materials may be used in the construction of the beer stein.[0006]Fremin, in U.S. Pat. No. 4,919,983 teaches that by using ...

[0008]Another embodiment of the present invention relates to a plurality of stackable steins. Each of the steins include a body formed from a) an outer cylindrical wall wider at a first base end than at an opposite first upper end; b) an inner cylindrical wall having a second base end and an opposite second upper end; wherein the first upper end and the second upper end form a common upper region and the first base end and the second base end extend to substantially a same orthogonal distance from the common upper region; and c) a frustoconical annular region formed between an outer surface of the inner cylindrical wall and an inner surface of the outer cylindrical wall. Moreover, the plurality steins are nested together in an arrangement from a bottom stein to a top stein whereby the common upper region of a lower stein in the arrangement is fitted within the frustoconical annular region of an adjacent, next-higher stein in the arrangement.

[0009]Yet another embodiment of the present invention relates to a kit of disposable steins that includes a plurality of stackable steins; a plurality of detachable bottoms, each bottom configured to releasably attach to the first base end of one of the plurality of stackable steins; and a plurality of detachable handl...
