Description

A kind of airtight lid for container

Technical field

The present invention relates to a kind of container cover, relate in particular to a kind of airtight lid for container.

Background technology

At present; The sealing container for storing that generally uses; Itself and the multiple different type of being combined with of lid; The formula of pressing, bolt connection type are generally arranged, and the halberd edge that also has the contact surface of use lid bottom and container to be provided with below O-ring seal or the lid is provided with groove or flange, in groove or flange, is with O-ring seal.But the seal cover cap of this structure for guaranteeing sealing effectiveness, often designs closelyr.Often need take very big strength could cover the lid of container or open, and also can cause cap seal not close sometimes because of carelessness, or the situation that causes seal cover cap to damage easily, and this had both wasted people's time, increased the weight of use cost again; Particularly for earthenware porcelain receptacle, because pottery will pass through and form by a firing, its deformation rate is higher; Its peristoma can not resemble metal or plastics make it accurate typing through mould, so the seal cover cap that present ceramic container for storing mated generally is to adopt buckle-type, it is protruding with card promptly to be provided with many card wings at the lid outward flange; When cover cap on container body and will block the wing and detain the time, block convex clip below the edge of container body peristoma and make lid become tight connection with container body, the airtight container of this structure downwards; Though its sealing property is better, use inconvenience, when covering down or opening; Need detain or open a plurality of card wings, make troubles for people's use.

Summary of the invention

Not enough for overcoming above-mentioned existing in prior technology, the present invention provides a kind of to have reliable sealing effect and lid and opens or cover all and be easy to easy to use and durable airtight lid for container.

The present invention is achieved in that a kind of airtight lid for container, comprises upper cover body and lower cover; Be provided with the halberd edge of stretching down at the edge of upper cover body; The halberd edge lower diameter of stretching down is slightly less than upper diameter and forms stepped appearance, and the lower cover edge is provided with the halberd edge of stretching, and the halberd edge of stretching under the upper cover body is socketed in the halberd edge outside of stretching on the lower cover; The halberd edge of stretching on the lower cover is provided with annular groove, is socketed with " falling 7 " type O-ring seal on the halberd edge of on annular groove reaches, stretching; In the upper surface of upper cover body one groove is set; Recess sidewall is provided with guide groove, and bottom portion of groove is symmetrically arranged with two through holes, is respectively arranged with pull bar in the through hole; Pull bar top and switch are flexibly connecting; The pull bar bottom is provided with a projection, and switch is provided with small convex pillar to the sidewall that is connected an end with pull bar top, and small convex pillar and guide groove are connected and can slide around guide groove; Lower cover upper surface and pull bar correspondence position are provided with two projections, are provided with draw-in groove in the projection, and the projection that the pull bar bottom is provided with is connected in the draw-in groove.

Said pull bar top and switch plate flexibly connect through latch.

Said upper cover body and lower cover are circular, oval, square or prismatic.

Realize the present invention; Because switch is connected the small convex pillar of sidewall setting and guide groove and can slide around guide groove, when being used need cover seal cover cap the time with airtight container, the switch handle under a side pressure; Because the effect of guide groove and pull bar; Lower cover moves up, and the halberd edge bottom of upper cover body edge setting is stretched into O-ring seal and O-ring seal is risen greatly, makes the airtight container sealing; When wanting uncover, switch is up drawing, and lower cover moves down and makes O-ring seal break away from the halberd edge bottom of upper cover body, and O-ring seal is got back on the halberd edge of lower cover, is easy to just lid opened; The present invention's compactness simple for structure has reliable sealing effect, and lid opens or cover all and be easy to, and is easy to use, is not easy again to damage, and can effectively reduce use cost.

Description of drawings

Fig. 1 is the structural principle scheme drawing of a kind of airtight lid for container of the present invention;

Fig. 2 is the birds-eye view of Fig. 1;
