Abstract

The invention provides a sealing cover suitable for containers with various specifications. The sealing cover comprises a surface cover, and the sealing cover is characterized in that a sealing gasketis covered under the surface cover, the outer edge of the surface cover and/or the sealing gasket is tilted, and the sealing gasket is connected with the outer edge of the surface cover, so that a hollow and deformable space is formed between the sealing gasket and the surface cover, a first through hole is arranged on the sealing gasket, a second through hole is arranged in the surface cover, and a one-way valve is arranged in the second through hole. The width of the end face of the sealing gasket is much larger than that of a traditional sealing ring, so that the sealing cover is suitablefor containers with various specifications.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a sealing cap suitable for containers of various specifications. Background technique [0002] The sealing cap is often used as a common article for sealing and preserving the mouth of the container, and usually includes an outer cover and an inner cover or a sealing ring arranged in the outer cover as a combination. However, the existing containers on the market have different specifications and sizes, and the types of containers include glassware, ceramic bowls, stainless steel boxes, etc., except that the flatness of the opening cannot be well guaranteed, and some openings have irregular shapes, which may easily cause the container The cooperation with the lid can not achieve the most suitable sealing state, and the sealing lid of a specific size can only be applied to the container of a specific size and shape, resulting in the uniqueness of the sealing lid. In order to solv...
