TECHNICAL FIELD
[0001] The utility model belongs to the bottle mouth sealing field, concretely relates to a bottle mouth sealing sheet. BACKGROUND
[0002] The design of the bottle mouth sealing structure is to ensure that the substances in the bottle do not leak, and also prevent the intrusion of external pollutants.
[0003] At present, the bottle mouth sealing structure existing in the market has the following implementation modes: 1. No gasket sealing structure: this structure usually includes three seals, which are a sealing ring, a top sealing ring and a side sealing ring. The sealing ring is deeply inserted into the inside of the bottle mouth, the top sealing ring is pressed on the bottle mouth plane, and the side sealing ring is surrounded on the outside of the top of the bottle mouth. This design ensures that the beverage does not leak and deteriorate when it is squeezed or collided during transportation or transportation; 2. Sterile cover sealing structure: the sterile cover also contains a three-seal structure, i.e. a sealing ring, a top sealing ring and a side sealing ring. After the cover is sealed, the sealing ring is deeply inserted into the inside of the bottle mouth, and the top sealing ring and the side sealing ring play an auxiliary sealing role; 3. Water cover sealing structure: the water cover sealing design is a two-seal structure, which is a sealing ring and a side sealing ring from inside to outside. After the cover is sealed, the sealing ring is deeply inserted into the inside of the bottle mouth, and plays a main sealing role; the side sealing ring is tightly attached to the outside of the top of the bottle mouth, and plays an auxiliary sealing role.
[0004] However, the above implementation requires the setting of multiple accessories (rings or rings), and the sealing effect is achieved by using them together, so on the one hand, if the multiple accessories are not properly matched, the sealing will fail; on the other hand, the multiple accessories also make it difficult to reduce the material cost.
