Abstract
The utility model discloses a bottle lip and bottle cap sealing structure with an anti-volatile function. The bottle lip and bottle cap sealing structure with the anti-volatile function comprises a bottle lip (1) and a bottle cap (2), the bottle lip (1) and the bottle cap (2) are provided with threads which are mutually matched, a seal ring (3) is arranged inside the bottle cap (2), the outer side of the seal ring (3) is in contact with the inner side of the battle lip (1), and the outer side of the seal ring is a conical surface. According to the bottle lip and bottle cap sealing structure with the anti-volatile function, the seal ring is arranged additionally inside the bottle cap, the outer side of the seal rings is in contact with the inner side of the bottle lip in design, and the contact surfaces of the seal ring and the bottle lip are processed into the conical surface, so that during the screwing of the bottle cap, the two contact surfaces can become more and more tight as being pressed continuously, and accordingly a good sealing effect is achieved and gas in a bottle is guaranteed not to volatilize.
Description
Technical field
The utility model relates to a kind of the have bottleneck of volatilization prevention function and the hermetically-sealed construction of 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 simple in structure, bottleneck with volatilization prevention function of good airproof performance and the hermetically-sealed construction of bottle cap are provided, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: have the bottleneck of volatilization prevention function and the hermetically-sealed construction of bottle cap, it comprises bottleneck and bottle cap, be provided with the screw thread that cooperatively interacts at bottleneck and bottle cap, in bottle cap, be provided with seal ring, the outside of seal ring contacts with the bottleneck inboard, and the outside of seal ring is the conical surface.
The conical surface lower end external diameter in the seal ring outside is little, the upper end external diameter is big.
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 contact surface of seal ring and bottleneck 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 outside of seal ring 3 is processed as the conical surface, the conical surface lower end external diameter in seal ring 3 outsides is little, the upper end external diameter is big, 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. one kind has the bottleneck of volatilization prevention function and the hermetically-sealed construction of 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 outside of seal ring (3) is the conical surface.
2. according to claim 1 have the bottleneck of volatilization prevention function and a hermetically-sealed construction of bottle cap, it is characterized in that: the conical surface lower end external diameter in seal ring (3) outside is little, the upper end external diameter is big.
