Container cover with sealable arrangement and its method thereof

Abstract

A container cover for sealing a container body includes a cover panel detachably coupling with an opening of the container body to enclose a receiving cavity thereof, and a sealable arrangement which includes a sealing element movably supported underneath the cover panel, and an actuation unit operatively mounted on top of the cover panel to move the sealing element between an unsealed and sealed position. At the unsealed position, the cover panel is free to detachably support at the opening, and at the sealed position, the sealing element is radially and outwardly moved to seal at and bias against the opening edge of the container body so as to seal the receiving cavity in an air-tight manner and to retain the cover panel in position.

Description

BACKGROUND OF THE PRESENT INVENTION[0001]1. Field of Invention[0002]The present invention relates to a container, and more particularly to a container cover with a sealable arrangement, wherein the sealable arrangement not only allows the container cover freely coupling with the container body when the sealable arrangement is held at its unsealed position but also ensures the container cover sealing with the container body when the sealable arrangement is held at its sealed position.[0003]2. Description of Related Arts[0004]It is advantageous for a container to be sealed, so that it is not permeable to liquid or air, so as to well preserve a content received in the container. Conventionally, the container has a container cover for sealably covering the container body. For some examples, a desiccant, powder, or such water absorbing material should be kept in an air-tight container to prevent water absorption from the atmosphere. Food items might be kept in an air-tight container to k...

AI Technical Summary

Benefits of technology

"The present invention provides a container cover with a sealable arrangement that can seal the container body in an air-tight and liquid-tight manner. The sealable arrangement allows the container cover to freely couple with the container body when in an unsealed position and securely retain the container cover at the opening of the container body when in a sealed position. The sealable arrangement requires a single operation movement to move between the unsealed and sealed positions, simplifying the operation of the container. The sealable arrangement is able to liquid-and-air-tightly seal the container body without the use of any tools beyond the container body and the container cover. The container cover can conveniently reseal the same container body after being removed from the container. The opening of the container body for being sealed by the container cover does not require a specific and complicated structure, reducing manufacturing costs."

Problems solved by technology

Because the container and container cover assembly relies on a small pressure between the ridges on the container and the container cover, the fit between the two parts is loose.

In a basic screw sealing assembly, only the interlocking ridges in the screw mechanism is used to seal the container, which may not be as air-tight as desired.

Both solutions have the shortcoming that the user must provide a large amount of force to seal the container properly, and it is difficult for the user to know when he has applied sufficient force.

Therefore, the seal provided by such a container cover is weakened at many points along the ring.

The seal may be improved by increasing the number of poles, but such a solution increases the cost of the container, and there always remains an unevenness of the seal between where the poles push against the ring and where the poles do not.
