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 ...

AI Technical Summary

Benefits of technology

The present invention relates to a stackable stein with a body that has a unique design that allows for easy stacking and detachment of individual steins. The stein has an outer cylindrical wall, an inner cylindrical wall, and a frustoconical annular region. The bottom of each stein has a closed base region, while the upper ends form a common upper region that extends to the same destination. The steins can be nested together, with the bottom stein fitting into the frustoconical annular region of the next-higher stein. The invention also includes a kit of disposable steins, detachable bottoms, and detachable handles for easy use. The frustoconical annular region of one stein fits into the common upper region of another, and the kit also includes a freezing tray for holding liquid coolant. The technical effects of the invention are improved effortless stacking and detachment of steins, as well as efficient cooling of liquid samples.
