Technical Field

The utility model relates to a bowl cover of container, especially a suction nozzle cup bowl cover based on elasticity auto-lock.

Background

The existing container for holding liquid, such as a water cup, is basically composed of a cup body and a cup cover screwed on the cup opening of the cup body. When using the drinking cup to drink water, there are two kinds of main modes:

firstly, the cup cover is unscrewed, and the lips are attached to the cup mouth of the cup body for drinking water.

Secondly, the cup cover does not need to be unscrewed, and water is drunk through a suction nozzle arranged on the cup cover. For example, patent No. ZL201821274383.1 discloses a flip-type nozzle cup cover, which includes: lid 1, top cap 2, 1 middle part of lid is equipped with delivery port 12, top cap 2 is installed in 1 upper end of lid through fixed pin 13, the bottom surface is provided with couple 14 under top cap 2, around having elasticity rubber band 15 on the couple 14, the elasticity rubber band 15 other end is walked around fixed pin 13 and is fixed inside lid 1, the bottom surface corresponds delivery port 12 position under top cap 2 and installs sealing plug 16, 1 one side of lid is equipped with according to keyway 17, 17 internally mounted has button 18 in the button groove, install reset spring 19 between button 18 and 17 medial surfaces in the button groove, button 18 upper portion is equipped with buckle 21, be equipped with the slot 20 that corresponds with buckle 21 on top cap 2.
