Problems solved by technology

[0005] The beneficial effects of the present invention are: a silica gel pad is provided and a through hole is provided on the end surface of the cup bottom, and the pressure of the cup body can be relatively balanced with the outside of the cup body through the deformation of the silica gel pad, thereby avoiding the pressure difference between the inside and outside of the cup body. The problem that the cup lid cannot be opened, easy to use

Embodiment Construction

[0008] Such as figure 1 shown. A water cup for preventing the locking of the cup cover, comprising a cup body 2, a cup cover 1 and a cup bottom 4, the cup cover 1 and the cup body 2 are connected by threads, the bottom of the cup body 2 is provided with a silica gel pad 3, and the cup bottom 4 It is connected with the silica gel pad 3 through threads, and the end surface of the cup bottom 4 is provided with a through hole.

[0009] When in use, when the cup body 2 is filled with hot water, the silicone pad 3 protrudes outward under the action of gravity, and the cup cover 1 is screwed on. When the water temperature in the cup body 2 changes and gradually decreases, the pressure in the cup body 2 Under the action of the pressure difference, the silicone pad 3 gradually rises to reduce the pressure difference in the cup body 2. It can also pass through the through hole on the bottom 4 of the cup and push the silicone pad 3 upwards with a little force to make the cup cover 1 and...

Abstract

The invention discloses a water cup capable of preventing a cup cover from being fastened, belongs to catering utensils and mainly solves the problem that when hot water is stored in a traditional water cup, the cup cover is difficult to open. The water cup comprises a cup body, a cup cover and a cup bottom, the cup cover and the cup body are in a threaded connection, a silica gel pad is arranged at the bottom of the cup body, the cup bottom is in the threaded connection with the silica gel pad, and a through hole is arranged on the end surface of the cup bottom. The water cup capable of preventing the cup cover from being fastened has the advantages that by means of the silica gel pad deformation, the relative balance between the pressure of the cup body and the pressure outside the cup body is achieved, thereby the problem that the cup cover can not be opened caused by the pressure difference between the interior and exterior of the cup body is solved, and the usage is convenient.

Description

technical field [0001] The invention relates to a dining utensil, in particular to a water cup which prevents the cup cover from being locked. Background technique [0002] In people's study, work and life, in order to supplement the water needed by the body at any time, it is necessary to drink water frequently to keep healthy. Therefore, when people go out, they generally carry a cup of hot water with them, so that they can drink when they are thirsty. When the temperature of the water drops, the pressure inside the cup decreases, and the atmospheric pressure outside the cup presses the lid tightly, increasing the pressure between the lid and the thread of the mouth of the cup, resulting in an increase in the maximum static friction force, so the lid is difficult to unscrew. Open, bring great inconvenience to use. Contents of the invention [0003] The object of the present invention is to provide a water cup that prevents the lid from being locked, and the water cup ha...
