Problems solved by technology

[0002] Existing cups have the problem of being difficult to open the cup lid when taking hot water
The specific reasons are as follows: after filling hot water, the air in the cup will expand, and after a period of time, as the water temperature decreases slowly, the air pressure in the cup will decrease; There is a certain air pressure difference between the inside and the outside world, making it difficult to open the lid
Especially when the cup is a glass cup, due to the poor thermal insulation of the glass cup, the water temperature in the cup will drop faster, resulting in a larger air pressure difference, and it will be more difficult to open the cup cover, which will bring greater inconvenience to the user. inconvenient

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] The invention provides an exhaust sealing ring. see Figure 1 to Figure 4 , the exhaust sealing ring 10 includes a sealing ring main body 1 . At least one surface of the sealing ring main body 1 is provided with a groove 2 . Specifically, the seal ring main body 1 has a first surface 1a and a second surface 1b oppositely disposed. A groove 2 is formed on the first surface 1a and / or the second surface 1b of the sealing ring main body 1 . It should be noted that, from the perspective of exhaust function, it...

Abstract

The invention provides an exhausting seal ring which comprises a seal ring body. The seal ring body has a first surface and a second surface; the first surface is disposed opposite the second surface. The first surface and / or the second surface is provided with a groove. The groove spirals and stretches to form a continuous exhaust duct along the outline of the seal ring body. The exhaust duct is provided with two opposite ports. One port of the exhaust duct formed by the groove communicates with the outside; the other port communicates with the inside of a cup. Due to the design that the groove forms the exhaust duct, the difference between internal gas pressure of the cup and ambient pressure is small. Therefore, users can open a cup lid easily.

Description

technical field [0001] The invention relates to a sealing ring, in particular to a sealing ring applied to a cup. Background technique [0002] Existing cups have the problem that it is difficult to open the cup lid when hot water is taken. The specific reasons are as follows: after filling hot water, the air in the cup will expand, and after a period of time, as the water temperature decreases slowly, the air pressure in the cup will decrease; There is a certain air pressure difference between the inside and the outside world, making it difficult to open the lid. Especially when the cup is a glass cup, due to the poor thermal insulation of the glass cup, the water temperature in the cup will drop faster, resulting in a larger air pressure difference, and it will be more difficult to open the cup cover, which will bring greater inconvenience to the user. inconvenient. Contents of the invention [0003] In view of the above problems, the object of the present invention i...
