Abstract

A leakage-proof thermos flask mouth consists of a flask cap, a spherical flask plug, a duckbill-shaped water outlet, an upper seal cap and a barb type throat pipe. The barb type throat pipe is inserted in the thermos flask mouth, and the upper seal cap is arranged on the barb type throat pipe. The duckbill-shaped water outlet is arranged on the upper seal cap, the spherical flask plug is arranged in the inner middle position of the duckbill-shaped water outlet, and the flask cap is arranged at the upper end of the spherical flask plug. The leakage-proof thermos flask mouth has the advantages of simple whole structure, convenient operation and use, good stability and high reliability. The barb type throat pipe extends into the flask bladder of the thermos flask and is sealed by three layers. Heat losses can be reduced, heat insulating effect can be improved, and water leakage can be well avoided. The spherical flask plug arranged adopts a float type. Water is convenient poured, the spherical flask plug can be automatically opened when water is poured, and the spherical flask plug can be automatically closed when the thermos flask is vertically put.

Description

Leakproof thermos flask mouth
Technical field:
The utility model relates to the thermos flask in the daily living article, relates in particular to leakproof thermos flask mouth.
