Abstract
The utility model relates to an explosion-proof bottle cap, which comprises a bottle mouth sleeve (1), an outer cover (2) and a gasket (3), wherein the bottle mouth sleeve (1) is a barrel-shaped body which is equipped with outer thread (11), the outer cover (2) is a cover-shaped body whose one end is closed, a baffle (23) whose middle portion is equipped with a pressure relief hole (22) is arranged in the outer cover (2), a pressure relief cavity (21) is formed between the baffle (23) and the closed end, an open end of the outer cover (2) is equipped with inner thread (24), the bottle mouth sleeve (1) and the outer cover (2) are connected through the thread, and the gasket (3) is located between the inner thread (24) of the outer cover (2) and the end portion of the bottle mouth sleeve (1). The utility model has the advantages that the explosion-proof effect is excellent, when opening, a bottle mouth is not damaged, after opening, and the bottle is capable of being closed against. When the pressure of the gas in the bottle is increased to a certain size, the gasket is capable of being pillared into the pressure relief cavity from the pressure relief hole, when the pressure reduces, the gasket automatically retracts, the utility model has the functions of pressure relieving and buffering, when opening, the outer cover is only needed to be rotated, the bottle is capable of being closed again through that the outer cover is rotated, and the use is convenient and clean.
Description
Technical field
The utility model relates to bottle cap, particularly explosion-proof bottle cap.
Background technology
The bottle explosion casualty accident often takes place in the beer of glass bottle and carbonated drink in production, carrying and opening process, for using explosion-proof bottle cap, some producer of safety guarantees safety, but existing explosion-proof bottle cap exists or explosion-proof effect is good inadequately, or damage bottleneck easily when opening, or osed top shortcoming once more after opening.
The utility model content
The purpose of this utility model provide a kind of explosion-proof effect good, do not damage bottleneck when opening, open after osed top explosion-proof bottle cap once more.
Technical solution of the present utility model is: it is made up of bottleneck cover, enclosing cover and packing seal, the bottleneck cover is for being provided with externally threaded cylindrical body, enclosing cover is an end osed top cover-shaped body, be provided with in the enclosing cover and closed end between form the dividing plate that pressure-releasing chamber, centre have relief hole, the open end of enclosing cover is provided with negative thread, the bottleneck cover is connected by screw thread with enclosing cover, and packing seal is between enclosing cover internal partition and bottleneck cover end.
Technique effect of the present utility model is: it have explosion-proof effect good, do not damage bottleneck when opening, open after osed top advantage once more, when gaseous tension is increased to a certain size in the bottle, packing seal can be supportted into pressure-releasing chamber from relief hole, when reducing, pressure bounces back automatically, have pressure release and buffering effect, only need the turn enclosing cover to get final product during unlatching, enclosing cover is screwed on and can seal once more, health again easy to use.
Description of drawings
Accompanying drawing is the utility model embodiment cutaway view.
The specific embodiment
As shown in the figure, it is made up of bottleneck cover 1, enclosing cover 2 and packing seal 3, bottleneck cover 1 is for being provided with the cylindrical body of outside thread 11, enclosing cover 2 is an end osed top cover-shaped body, be provided with in the enclosing cover 2 and closed end between form the dividing plate 23 that pressure-releasing chamber 21, centre have relief hole 22, the open end of enclosing cover 2 is provided with negative thread 24, and bottleneck cover 1 and enclosing cover 2 are connected by screw thread, and packing seal 3 overlaps between 1 end at enclosing cover 2 internal partitions 24 and bottleneck.The inwall of bottleneck cover 1 is provided with bottleneck draw-in groove 12.The open end of enclosing cover 2 is provided with and is stuck in the seal mouth ring 25 that links to each other on the bottleneck cover 1, with enclosing cover 2 interruptions.The periphery wall of enclosing cover 2 is provided with anti-skidding line 26.The material of bottleneck cover 1 and enclosing cover 2 is plastics.Packing seal 3 is the high elastic rubber pad.
