The anti-corrosion bottle cap is covered on the bottle mouth, the top of the bottle mouth is propped under the sealing rubber ring outside the convex ring, the sealing rubber ring is made of elastic rubber materials, the sealing rubber ring deforms after extrusion and has certain elasticity, when the bottle cap is taken down from the bottle mouth, the external force is withdrawn, the sealing rubber ring recovers the original shape under the elasticity of the sealing rubber ring, and after the bottle cap is screwed, a certain pressure exists between the anti-corrosion pad and the bottle mouth, so that the sealing effect is good, and the reagent is not easy to leak.
Description
Technical Field
The utility model belongs to the technical field of bottle caps, and particularly relates to an anti-corrosion bottle cap.
Background
In the fields of chemical experiments, product inspection and the like, reagents are required to be placed in reagent bottles, and the reagent bottles are covered with bottle caps. The bottle cap is generally made of plastic materials, and because some reagents have strong corrosiveness, the reagent bottle shakes or topples over during the storage or transportation of the reagents, so that the reagents are contacted with the bottle cap, and the bottle cap is corroded and damaged, so that the reagents volatilize or leak.
In order to avoid the bottle cap to be corroded, the inner side of the top of the bottle cap is provided with a corrosion-resistant pad, the bottle cap is screwed on the bottle mouth, the corrosion-resistant pad separates the reagent from the bottle cap body, and the bottle cap is corroded due to the fact that the corrosion-resistant pad is poor in elasticity and poor in sealing performance after being used for a period of time, and the reagent is leaked and contacts with the bottle cap.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the anti-corrosion bottle cap with long service life and good sealing effect.
In order to solve the problems, the anti-corrosion bottle cap adopts the following technical scheme: the anti-corrosion cover comprises a cover body with threads on the inner side surface, wherein a convex ring is arranged on the inner side of the top of the cover body and close to the center, a sealing rubber ring is arranged between the convex ring and the side wall of the cover body, and an anti-corrosion pad is arranged below the sealing rubber ring and the convex ring.
The additional technical characteristics are as follows:
the outer side of the convex ring is in a truncated cone shape with a large upper end diameter and a small lower end diameter;
the ratio of the thickness of the sealant ring to the height of the convex ring is 1:3-1:2, the anti-corrosion pad on the radial outer side of the convex ring is bent upwards, and the radial outer side edge of the anti-corrosion pad is propped against the side wall of the cover body.
Compared with the prior art, the anti-corrosion bottle cap provided by the utility model has the following advantages: firstly, because the anti-corrosion bottle cap comprises a cap body with threads on the inner side, a convex ring is arranged on the inner side of the top of the cap body and close to the center, a sealing rubber ring is arranged between the convex ring and the side wall of the cap body, anti-corrosion gaskets are arranged below the sealing rubber ring and the convex ring, the anti-corrosion bottle cap is covered on a bottle opening, the top of the bottle opening is propped against the lower part of the sealing rubber ring on the outer side of the convex ring, the sealing rubber ring is made of elastic rubber materials, the sealing rubber ring is deformed after being extruded and has certain elasticity, when the bottle cap is taken down from the bottle opening, the external force is removed, the sealing rubber ring returns to the original shape under the self elasticity, and after the bottle cap is screwed, certain pressure exists between the anti-corrosion gaskets and the bottle opening, the sealing effect is good, and the reagent is not easy to leak; secondly, as the outer side of the convex ring is in a truncated cone shape with a large upper end diameter and a small lower end diameter, when the bottle cap is screwed, the convex ring is inserted into the inner side of the bottle mouth, so that part of the anti-corrosion pad is positioned between the convex ring and the bottle mouth, and the bottle mouth is further sealed by the anti-corrosion pad, thereby improving the sealing effect; thirdly, as the ratio of the thickness of the sealant ring to the height of the convex ring is 1:3-1:2, the anti-corrosion pad at the radial outer side of the convex ring is bent upwards, and the radial outer side edge of the anti-corrosion pad is propped against the side wall of the cover body, so that the sealing effect is better.

Description of the embodiments
The structure and the principle of use of the anti-corrosion bottle cap according to the present utility model will be described in further detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, 2, 3 and 4, the anti-corrosion bottle cap of the present utility model comprises a cap body 2 with threads 1 on the inner side surface, a convex ring 3 is arranged near the center on the inner side of the top of the cap body 2, a sealant ring 5 is arranged between the convex ring 3 and the side wall 4 of the cap body 2, and an anti-corrosion pad 6 is arranged below the sealant ring 5 and the convex ring 3.
The anti-corrosion bottle cap is covered on the bottle mouth, the top of the bottle mouth is propped under the sealing rubber ring 5 outside the convex ring 3, the sealing rubber ring 5 is made of elastic rubber materials, the sealing rubber ring 5 deforms after being extruded and has certain elasticity, when the bottle cap is taken down from the bottle mouth, the external force is withdrawn, the sealing rubber ring 5 recovers the original shape under the elasticity of the external force, and after the bottle cap is screwed down, a certain pressure exists between the anti-corrosion pad and the bottle mouth, so that the sealing effect is good, and the reagent is not easy to leak.
The outer side of the convex ring 3 is in a truncated cone shape with a large upper end diameter and a small lower end diameter, and when the bottle cap is screwed, the convex ring is inserted into the inner side of the bottle mouth, so that part of the anti-corrosion pad is positioned between the convex ring and the bottle mouth, the bottle mouth is further sealed by the anti-corrosion pad, and the sealing effect is improved.
The ratio of the thickness of the sealant ring 5 to the height of the convex ring 3 is 1:3-1:2, the anti-corrosion pad 6 on the radial outer side of the convex ring 3 is bent upwards, and the radial outer edge of the anti-corrosion pad 6 is propped against the side wall 4 of the cover body 2, so that the sealing effect is better.
The protection scope of the present utility model is not limited to the above embodiments, and falls within the protection scope of the present utility model as long as the structure is the same as or similar to the structure of the anti-corrosion bottle cap of the present utility model.
