Abstract
The utility model relates to an explosion-proof cover for a chemical material container, which comprises an external cover body. The utility model is characterized in that an inner cover which is inserted in a container opening is arranged in the external cover body; the external cover body and the inner cover body are respectively provided with a mutually engaged structure which is integrally formed in use. A convex edge for enclosing the container opening is arranged on the periphery of the inner cover body; a small hole is arranged on the center of the inner cover body; a cushion with a hollow elastic plunger is plugged in the small hole; an air exit hole is arranged at the center of the external cover body. The utility model has the superiority that the structural design is felicitous, and the utility model can perform the function of safe decompression and avoids the accidents of explosion, environmental pollution and injury which are caused by a great amount of gas produced by the content in the container which is used for enclosing chemicals; the simple structure, and the cost is low, and the popularization and use are convenient.
Description
The utility model relates to a kind of lid of wrapper packaging container mouth, particularly a kind of Explosion-proof cap that is used for chemical industry articles for use packing container.
At present, the general lid that is used to encapsulate chemical industry articles for use vessel port only plays the anti-leakage of soaking, can not be with air scavenge unnecessary in the container, when packing container when temperature is more than 30 ℃, its content can produce a large amount of gases and can not discharge, make the container gross distortion thus, very the person also may set off an explosion, and causes contaminated environment, hurts sb.'s feelings and causes economic loss.
The purpose of this utility model is to design a kind of Explosion-proof cap that is used for chemical industry articles for use packing container, and it can overcome above-mentioned shortcoming, and decapacitation has had the anti-outer effect that gas in the timely eliminating container can also be arranged of effect of soaking leakage.
The technical solution of the utility model: a kind of Explosion-proof cap that is used for chemical industry articles for use packing container, comprise outer cover, it is characterized in that in said outer cover, being equipped with an inner cap that is embedded in the vessel port, each have the mutual occlusion structure that forms one in use on outer cover and the interior lid, inner cap has the convex edge of packaging container mouth on external week, there is aperture at interior lid center, and the aperture place is plugged with a rubber cushion with hollow resilient plug; There is a deflation hole said outer cover center.
Above-mentioned said outer cover and vessel port can be to be threaded and also can be flush fit and be connected.
All separately mutual occlusion structures that forms one in use can be and each have an outer shroud and lining ring on outer cover and the interior lid on above-mentioned said outer cover and the interior lid, and outer shroud and ring end, lining each have and be the concavo-convex of mutual interlock.
Using method of the present utility model: at first, interior lid is buckled in the vessel port place, and will be in the elasticity aperture at interior lid center with the rubber cushion plug of hollow resilient plug, then, buckle enclosing cover again, the end that each have on outer cover and the interior lid this moment be mutual interlock in ring and the mutual fastening of outer shroud, last, by outer cover or according to screw thread or be flush fit and vessel port encapsulates tightly.During use, when producing in the container when having gas to reach 0.5 kilogram, the rubber cushion with hollow resilient plug of plug in the aperture of interior lid center can be exposed by gas jack-up and meet the crack, thereby plays the effect of safety relief.
Preceence of the present utility model is: 1, structure design is ingenious, can play the effect of safety relief, has avoided that its content in the encapsulation chemical industry articles for use container can produce that a large amount of gases may set off an explosion, contaminated environment, the accident of hurting sb.'s feelings; 2, simple in structure, productive costs is low, conveniently promotes the use of.
Further specify present technique below in conjunction with drawings and Examples.
Fig. 1 cuts open structural representation for the related a kind of overall package side that is used for the Explosion-proof cap of chemical industry articles for use packing container of the utility model.
Fig. 2 cuts open structural representation for the related a kind of branch side that is used for the Explosion-proof cap of chemical industry articles for use packing container of the utility model.
Wherein 1 is deflation hole, 2 is outer cover, and 3 is interior lid, and 4 are the rubber cushion with hollow resilient plug, 5 is the rubber cushion deflation hole, 6 is the screw thread that outer cover combines with vessel port, and 7 is container, and 8 is the convex edge of external week of inner cap going up the packaging container mouth, 9 is the outer shroud on the outer cover, 10 be on the interior lid in ring, 11 be that interlock on the outer shroud is concavo-convex, 12 interlocks that encircle for the lining are concavo-convex.
Embodiment: a kind of Explosion-proof cap (seeing accompanying drawing 1 and 2) that is used for chemical industry articles for use packing container, comprise outer cover 2, it is characterized in that in said outer cover 2, being equipped with an inner cap 3 that is embedded in 7 mouthfuls in the container, each have the mutual occlusion structure that forms one in use on outer cover 2 and the interior lid 3, the convex edge 8 that the packaging container mouth is arranged on interior lid 3 peripheries, there is aperture 5 at interior lid 3 centers, and aperture 5 places are plugged with a rubber cushion 4 with hollow resilient plug; There is a deflation hole 1 said outer cover 2 centers.
Above-mentioned said outer cover 2 can be screw thread 6 with container 7 oral areas and is connected (as Fig. 1).
All separately mutual occlusion structures that forms one in use (seeing accompanying drawing 1 and 2) can be and each have an outer shroud 9 on outer cover 2 and the interior lid 3 and the lining encircles 10 on above-mentioned said outer cover 2 and the interior lid 3, and outer shroud 9 and lining are encircled 10 ends and each had and be concavo-convex 11 and 12 of mutual interlock.
