Sealing cover and sealing container

Abstract

This disclosure provides a sealing cover, belonging to the technical field of sealing containers. The sealing cover comprises: a cover body provided with a through hole; a knob, rotatably arranged on one side of the cover body and provided with protrusion parts; a bottom plate, movably arranged on the other side of the cover body and able to move close to or away from the cover body, the bottom plate being provided with a linkage part, the linkage part passing through the through hole, spiral grooves being formed in a peripheral surface of the linkage part, the protrusion parts being connected to the spiral grooves and able to move along the spiral grooves; and a seal ring arranged between the bottom plate and the cover body. Further provided is a sealing container, comprising a sealing cover and a container body, wherein a cover body of the sealing cover is fitted to cover the container body. This disclosure has the beneficial effects as follows: the knob is rotated to drive the bottom plate to move close to or away from the cover body. When the bottom plate is close to the cover body, the seal ring can be squeezed and deformed to open outward, so that the seal ring pushes against and is connected to the inner wall of the container to achieve the sealing effect, and the operation is simple and convenient.
