Benefits of technology

The objective of this patent is to provide a sealing cover that can be pressed to seal or unseal a box body, making it easier to operate.

Problems solved by technology

However, the user must apply larger force to the sealing cover for closing the box body with, which results in difficulties in removal of the sealing cover from the box body.
The sealing effect is adversely affected if the tightness between the annular gasket and the inner periphery of the box body is reduced to permit easy removal of the sealing cover.

Embodiment Construction

[0021]FIGS. 1-5 show a sealing cover according to the present invention in an unsealing state. The sealing cover includes a base 1, a lower lid 2, a gasket 3, two supports 4, a seat 5, a pressing member 6, an upper lid 7, a positioning ring 8, and a shield 9. The base 1, the lower lid 2, and the gasket 3 form a sealing unit 10. The seat 5, the pressing member 6, the upper lid 7, and the positioning ring 8 form a control unit 20. The base 1 includes an outer periphery having an engagement edge 11. The base 1 further includes a central portion having an abutment face 12 and an engaging portion 13. A plurality of pivotal columns 14 and an annular groove 15 are defined in a top face of the base 1. A first spring 16 is received in the annular groove 15 and abuts a bottom wall of the annular groove 15.

[0022]The lower lid 2 is mounted on top of the base 1 and includes a bottom wall 21 and an annular wall 22 formed along an outer periphery of the bottom wall 21, with an engagement edge 23 p...

Abstract

A sealing cover includes a base, a lower lid, and a soft, deformable gasket mounted between outer peripheries of the base and the lower lid. An upper lid includes a positioning hole having an inner periphery with higher and lower positioning grooves, with a lower positioning groove located between two adjacent higher positioning grooves. A positioning ring includes upper and lower positioning protrusions. The upper lid can be pressed and moved downward relative to the lower lid, so that the pressing member presses against the upper positioning protrusions of the positioning ring, causing rotational movement of the positioning ring through an angle and changing the spacing between the base and the lid. When the upper lid is released, the upper positioning protrusions are engaged in higher positioning grooves or the lower positioning grooves so that the sealing cover is in a sealing state or an unsealing state.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a sealing cover and, more particularly, to a sealing cover with enhanced sealing effect while allowing easy operation.[0002]A conventional sealing box generally includes a sealing cover having a soft annular gasket pressing against an inner periphery of the box body to provide the desired sealing effect. However, the user must apply larger force to the sealing cover for closing the box body with, which results in difficulties in removal of the sealing cover from the box body. The sealing effect is adversely affected if the tightness between the annular gasket and the inner periphery of the box body is reduced to permit easy removal of the sealing cover.BRIEF SUMMARY OF THE INVENTION[0003]An objective of the present invention is to provide a sealing cover that can be pressed to seal or unseal a box body, providing operational convenience.[0004]The sealing cover includes a sealing unit and a control unit. The sealing un...
