Description
Technical Field
The utility model belongs to the technical field of sealed bottle caps, and particularly relates to a sealed bottle cap with a gasket.
Background
In production and life, a large number of articles need to be stored in a sealed manner, particularly food and medicines, and the effect and the validity of the storage tightness are greatly influenced. The existing bottled medicine is usually sealed at the bottle mouth through a sealing gasket made of aluminum foil and paper, and has the defects that: the sealing is unreliable, and the sealing gasket is not easy to form closed fit with the bottle mouth due to the lack of elasticity; the assembly process is complex, and an electromagnetic induction sealing machine is needed to heat the sealing gasket; the sealing effect is lost after the seal is opened. There are also sealing gaskets made of aluminum foil and rubber, which, although they have good sealing properties, migrate rubber and contaminate the medicine.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides the sealing bottle cap with the gasket, which is simple in structure and convenient to process, assemble and use.
The utility model provides the following technical scheme: the utility model relates to a sealing bottle cap with a gasket, which comprises a bottle cap body, wherein inner threads are arranged on the inner wall of the bottle cap body, a sealing column is arranged in the middle of the top wall of the bottle cap body, an arc boss is axially arranged on the outer side surface of the sealing column, the arc boss is connected with the upper part and the lower part of the sealing column in an arc line manner, an end face sealing gasket is arranged on the top wall of the bottle cap body and is arranged outside the sealing column, the end face sealing gasket is positioned above the arc boss, and the width of the end face sealing gasket is smaller than the width between the sealing column and the side wall of the bottle cap body in an initial non-extrusion state.
Furthermore, the circumference of the upper part of the bottle cap body is arranged in a circular truncated cone-shaped structure.
Further, the outer side wall of the bottle cap body is provided with straight knurls.
Furthermore, the ratio of the thickness of the top wall of the bottle cap body to the height of the bottle cap body is 1 (8-9).
Preferably, the bottle cap body is a polyethylene bottle cap body.
The utility model with the structure has the following beneficial effects: according to the sealing bottle cap with the gasket, the arc boss axially arranged in the bottle cap is in interference fit with the inner cavity of a bottle opening, so that a first sealing effect is achieved, the bottle cap body is rotated to the bottom through the internal and external threads, and a second sealing effect is achieved by utilizing the end face sealing gasket; the integral sealing effect is excellent, and the leak resistance is good.
