A kind of anti-overflow thermal insulation teacup with thermal insulation cover can be used as teacup

Abstract

The invention provides a water-overflow-preventing heat preservation teacup with a heat preservation cover capable of serving as a teacup body, and relates to teacups. A cup cover (1) is arranged on the upper portion of an inner cup body (6), an annular protrusion (9) is arranged on the outer edge of the lower end of the inner cup body (6), a protruding strip (11) is arranged on the lower portion of the annular protrusion (9), and the position, above the protruding strip (11), of the annular protrusion (9) is provided with an external thread (15); an internal thread (12) arranged on the inner surface of the lower end of the heat preservation cover (3) is connected with the external thread (15) of the annular protrusion (9) on the outer edge of the lower end of the inner cup body (6). According to the heat preservation teacup, the external thread is arranged on the lower portion of the inner cup body, the lower portion of the heat preservation cover is connected with the external thread of the lower portion of the inner cup body, a double water-overflow-preventing structure is formed by the cup cover and the heat preservation cover, the heat preservation cover can serve as the teacup body after being taken down, and the purpose that the water-overflow-preventing heat preservation teacup is multifunctional is achieved.

Description

【Technical field】 [0001] The invention relates to a teacup, in particular to a water-preventing thermal insulation teacup whose thermal insulation cover can be used as the teacup. 【Background technique】 [0002] As is known, most commercially available thermal teacups are made of inner and outer double-layer glass or inner and outer double-layer food-grade plastics, and the function of the outer insulation layer is limited to heat preservation; Some people carry the teacup and soak the tea leaves in the cup for a long time, which will cause the tea taste to be very strong at the beginning, but the tea taste is very weak later, especially Tieguanyin tea is not suitable for long-term soaking, so it is difficult to do it when you are away from home. , this is mainly due to the limitation of the current teacup function; the existing teacup is usually placed in the bag when going out, once the cup cover is not tightly sealed, it is easy to wet the documents and clothing in the ba...

[0002] As is known, most commercially available thermal teacups are made of inner and outer double-layer glass or inner and outer double-layer food-grade plastics, and the function of the outer insulation layer is limited to heat preservation; Some people carry the teacup and soak the tea leaves in the cup for a long time, which will cause the tea taste to be very strong at the beginning, and the tea taste will be very weak later, especially Tieguanyin tea is not suitable for long-term soaking, so it is difficult to do it when you are away from home. , this is mainly because the function of the current teacup is limited; the existing teacup is usually placed in the bag when going out, and once the lid of the cup is not tightly sealed, it is easy to wet the documents and clothes in the bag
