Description

Sealing aluminum foil lifting gasket convenient to open Technical Field The invention relates to the field of sealing gaskets, in particular to a sealing aluminum foil lifting gasket convenient to open. Background In the prior art, the sealed package is an important link for guaranteeing the storage and transportation safety and the use stability of products, and is widely applied to the fields of chips, foods, medicines, cosmetics and the like, and is particularly common in sealing plastic containers such as medicine bottles, engine oil bottles, milk powder cans and the like and various packaging containers such as plastics, paper, aluminum and the like. After the container is filled, a sealing gasket or a heat-sealing aluminum foil sealing sheet is arranged at the edge of the bottle mouth or the opening to realize sealing, so that the contents are prevented from being wetted, polluted or spoiled, but the existing sealing structure has a plurality of defects. On the one hand, the opening of the seal is inconvenient, whether the seal gasket or the aluminum foil seal piece is used, when a user uses the seal gasket, the user often needs to cut open or puncture the seal gasket with the help of a sharp tool or a nail or puncture the seal gasket with great effort, the operation is complicated, certain potential safety hazards exist, and meanwhile, the content is spilled out due to improper opening modes, so that the use experience is influenced; on the other hand, when the content in the container is not used up once, after the user covers the cover again, the original sealing gasket is destroyed, the sealing effect is obviously deteriorated, the invasion of impurities such as outside air, moisture and the like cannot be effectively blocked, the content is easy to oxidize, damp and deteriorate, the quality and the use safety of the product are affected, and the problem is more remarkable especially for products with higher requirements on the storage environment such as medicines, foods and lubricating oil.
