Abstract
The utility model discloses a volatilization prevention bottle cover, which comprises a bottle mouth (1) and a bottle cover (2), wherein the bottle mouth (1) and the bottle cover (2) are provided with threads which are matched with each other, a seal ring (3) is arranged in the bottle cover (2), the outer side of the seal ring (3) is in contact with the inner side of the bottle mouth (1), and a conical surface is arranged on the inner side of the bottle mouth (1). The seal ring is arranged in the bottle cover, the outer side of the seal ring is in contact with the inner side of the bottle mouth, bottle mouth surfaces of two contact surfaces are processed into the conical surfaces, and the two contact surfaces can be pressed more and more tightly during the process of screwing of the bottle cover, thereby achieving excellent sealing effect, and guaranteeing gas in a bottle not to volatilize.
Description
Technical field
The utility model relates to a kind of volatilization prevention bottle cap, belongs to the airtight container technical field.
Background technology
Mostly the sealing of existing container is to adopt thread seal or rubber plug to seal, but in use all there is the relatively poor problem of leak tightness in above-mentioned sealing means, and when particularly storage medium was volatile liquid or solid in it, leak tightness will be difficult to guarantee more.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of volatilization prevention bottle cap of simple in structure, good airproof performance is provided, can overcomes the deficiencies in the prior art.
The technical solution of the utility model is: the volatilization prevention bottle cap, and it comprises bottleneck and bottle cap, is provided with the screw thread that cooperatively interacts at bottleneck and bottle cap, is provided with seal ring in bottle cap, and the outside of seal ring contacts with the bottleneck inboard, and the inboard of bottleneck is the conical surface.
The conical surface lower end external diameter of bottleneck inboard is big, the upper end external diameter is little.
Compared with the prior art, the utility model installs seal ring additional in bottle cap, the outside with seal ring during design contacts with the bottleneck inboard, and the bottleneck face of two contact surfaces is processed as the conical surface, like this in the process that bottle cap is tightened, two contact surfaces will be pressed tighter and tighter, thereby reach good sealing effectiveness, guarantee that bottle interior gas can not volatilize.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.；
The specific embodiment
Embodiment 1: shown in Fig. 1, the bottleneck 1 and the bottle cap 2 that store object interconnect by the screw thread that cooperatively interacts, for increasing leak tightness, be provided with seal ring 3 in bottle cap 2, the outside of seal ring 3 contacts with bottleneck 1 inboard, and the inboard of bottleneck 1 is the conical surface, the conical surface lower end external diameter of bottleneck 1 inboard is big, the upper end external diameter is little, in the process of tightening bottle cap 2, the outside conical surface of seal ring 3 will contact tighter and tighter with bottleneck 1 inboard like this, realizes sealing.
Claims (2)
1. volatilization prevention bottle cap, it comprises bottleneck (1) and bottle cap (2), be provided with the screw thread that cooperatively interacts at bottleneck (1) and bottle cap (2), it is characterized in that: in bottle cap (2), be provided with seal ring (3), the outside of seal ring (3) contacts with bottleneck (1) inboard, and the inboard of bottleneck (1) is the conical surface.
2. volatilization prevention bottle cap according to claim 1 is characterized in that: the inboard conical surface lower end external diameter of bottleneck (1) is big, the upper end external diameter is little.
