Abstract

The invention provides a sealing cover with a self-sealing structure and capable of being vacuumized, comprising a cover body, a vacuumizing mechanism arranged on the cover body, a sealing body which is connected to the cover body and can generate elastic deformation. The sealing cover is characterized in that a skirt part is arranged at the lower end of the cover body; the sealing body is sleeved at the lower end of the skirt part and is in a circular ring shape; a closed hollow cavity is formed between the skirt part and the sealing body; preferably, the skirt part extends outwards from the lower end of the cover body and is inclined downwards; a groove is arranged at the part above the skirt part, which is close to the outer side; a skirt part inner ring groove with an opening which is arranged outside the circle is arranged at the lower end of the inner edge of the skirt part in a vertical direction; the section of a sealing piece is in a semi-arc shape and the inner edge of the sealing piece is embedded into the skirt part inner ring groove; and the outer edge of the sealing piece extends in the lower direction of the skirt part to wrap the skirt part and extends downwards to form a sealing piece bulge adapted to the groove. The sealing cover disclosed by the invention has a simple structure and is very practical; the convenience of utilization is greatly improved; and the sealing cover can be applicable to utensils with different opening diameters.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a sealing cover for vacuum preservation of food. Background technique [0002] People preserve food by adding a cover to the container, but the storage time of the food in this container is relatively short; in order to prevent the outside air from entering the container, a vacuum pump is generally used to extract the air in the container. This operation is not only complicated, but also And this container is generally disposable, can not be reused, and cost is also relatively high, only uses on the commodity that sells or special article; Because use is inconvenient, seldom adopts this method to preserve food in people's daily life. [0003] At present, there is a kind of special fuse box that can be vacuumed on the market. The fuse box with this structure can use the vacuum mechanism provided on the cover to extract the gas in the box, which is more convenient to use; however, ...
