Double-layer drinking cup

Abstract

The invention relates to a double-layer drinking cup, comprising a cup body (1). The cup body is made of high borosilicate material and comprises an inner layer (2), an outer layer (3) and a middle interlayer space (4), wherein mixed liquid (5) is contained in the interlayer space and is prepared from distilled water and edible alcohol; the volume ratio of the distilled water to the edible alcohol is 4:1 to 9:1; and the mixed liquid accounts for 70%-80% of the volume of the interlayer space. The double-layer drinking cup has simple structure and is convenient to use. When in use, the double-layer drinking cup has good cooling effect; beverage can be directly poured into the double-layer drinking cup for drinking as long as the double-layer drinking cup is taken out of a refrigerator, the double-layer drinking cup can cool beverage directly under the cold accumulation effect of the mixed liquid without using ice blocks or wasting power, so that the double-layer drinking cup can be widely applied to places such as families, hotels, restaurants and wine bars and the like, the operating cost of the hotels, the restaurants and the wine bars and the like can be reduced, and the double-layer drinking cup has good technical and economic benefits.

Description

However, this way of cooling drinks with ice cubes is extremely wasteful of ice cubes. , after the drink is finished, the ice cubes need to be discarded, which greatly increases the operating costs of restaurants, bars and other places, and it is necessary to buy ice cubes or make ice cubes regularly, which is very inconvenient to use

[0003] In addition, there are also directly full beverage containers, such as beer bottles, to be frozen in the refrigerator, and the chilled beer is directly supplied to the guests when they drink, but this method is very wasteful of electric energy, because no matter whether there are guests Purchased, beer needs to be kept in sufficient quantities in the refrigerator for freezing
