Abstract

The utility model discloses a decompression anti-explosion device for a beer glass bottle, which has the decompression action and can prevent the beer glass bottle from exploding. The utility model is a sealing cover for a beer glass bottle mouth, and is composed of a metal cover (1), a gasket (2) and an inner plug (3), wherein, the inner plug (3) is plugged in the plug hole of the metal cover (1). The gasket (2) is sheathed on the external wall of the plug body (4). Then the air holes (5) which are uniformly distributed on the external wall are plugged. When the pressure in the bottle is greater than the atmospheric pressure, the inner plug and the air holes are pushed up by the internal pressure. When the air holes are higher than the upper surface of the gasket, pressured beer can effuse through air holes from the slit among the gasket, the metal cover and the inner plug. Then the internal pressure is decompressed rapidly and the bottle explosion is avoided. The utility model is very advantageous to beer industry and social public.

Description

The decompression explosion-proof device of beer glass bottle

The utility model relates to the seal closure of glass bottle, is a kind of decompression explosion-proof device of glass bottle of splendid attire beer.

The seal cover cap of existing beer glass bottle opening is made up of crown cap and packing ring, with capper they is fastened on the glass bottle opening.Because beer is fermented beverage, beer has gas to produce in the loading and unloading transportation, and pressure of the inside of a bottle is increased.Although light industry mutually has clearly regulation to the voltage endurance capability of beer glass bottle, because beer glass bottle explosive incident once took place for repeated usage and the beer quality and the other reasons of beer glass bottle, to this, once there was report in news media.

The purpose of this utility model provides a kind of decompression explosion-proof device that can prevent the blast of beer glass bottle with depressurization.

The technical solution of the decompression explosion-proof device of a kind of beer glass bottle that the utility model provides is to set up a Zhi Neisai, simultaneously original crown cap and packing ring is carried out the conformability improvement.The end face of plug not vertically is connected with the cylinder type hollow plug in being somebody's turn to do, and spares to be furnished with at least two pores on the cock body wall, has the vertical bar that is communicated with it and stitch this seam below pore, and the cock body base is disconnected, and the outside turnup in cock body base is held packing ring.The end face of crown cap has consent to lower recess in the depressed part center, plug cock body outer wall in this consent periphery is close to.Packing ring is an annular arrangement, and thick outer thin in the whippy anchor ring, interior ring peripheral sleeve is sealed pore on interior plug cock body outer wall.After adopting this structure, when beer glass bottle internal pressure is internally filled in the pressure of end face above atmosphere, move on filling in vertically in internal pressure promotes, packing ring is compressed, when moving on the pore on the cock body wall above upper surface of washer, band in the beer glass bottle presses beer will be from the slit of pore between crown cap, packing ring, interior plug to let out to bottle is excessive, and pressure of the inside of a bottle descends rapidly, thereby avoids glass bottle to blast.

The utility model only need increase the shape of a Zhi Neisai and corresponding change crown cap and packing ring, just can prevent explosion accident, avoids injury to take place, and gives a kind of sense of security of people, and this all is very favorable to the beer industry and the public.

The utility model is described in more detail to stop embodiment below in conjunction with accompanying drawing and tool.

Fig. 1 is that the master of the specific embodiment of the decompression explosion-proof device of the utility model beer glass bottle looks cutaway view.

Fig. 2 be among Fig. 1 A-A to view.

Fig. 3 is the constitution diagram after moving beyond the Great Wall in shown in Figure 1.

The utility model comes down to a kind of seal cover cap with beer glass bottle opening of depressurization.As shown in Figure 1, this explosion protection is made up of crown cap 1, packing ring 2 and Nei Sai 3.

Reprocessing pore 5 and bar seam 6 after the 3 usefulness plastic material one-shot formings of interior plug, as shown in Figure 2, this specific embodiment is provided with 4 pores and 4 bars seams.Earlier interior plug cock body is filled in the consent of crown cap 1, on the outer wall of plug cock body 4, at last the outside turnup in cock body base is held packing ring in then packing ring 2 being enclosed within.Through after the above-mentioned assembling, promptly constitute the seal cover cap that a beer glass bottle that can prevent to explode with depressurization is used.

Enter the consent of crown cap but also helped the cock body flange in bar seam 6 had not only helped and hold packing ring 2, plug 3 and packing ring 2 and crown cap 1 snug fit in making.

Packing ring 2 should select for use the good rubber of elasticity to manufacture, and utilizes its better elastic that the pore on the cock body wall 5 is blocked, to guarantee to realize conventional seal request.

Shaping of crown cap 1, the best one-shot forming of the consent of its depressed part and center thereof also can add respectively mutually.Their dimensional accuracy should be coincide with the dimensional accuracy of the region of interest of interior plug.

The utility model explosion protection promptly has the seal cover cap of depressurization, also is with capper it to be pressed solidly oral area periphery at beer glass bottle 7.

Fig. 3 has provided decompression state.When beer glass bottle internal pressure during greater than bar pressure, band presses beer that interior plug 3 is promoted to move, when the pore on the cock body wall 5 surpasses the upper surface of packing ring 2, band presses beer to overflow from pore 5, overflow outside bottle the slit between crown cap 1, packing ring 2, interior plug 3 again, pressure of the inside of a bottle descends rapidly, thereby avoids the glass bottle blast.

Claims (1)

1. A kind of decompression explosion-proof device of beer glass bottle comprises crown cap and packing ring, it is characterized in that:

   A, also has a Zhi Neisai (3), should vertically be connected with cylinder type hollow cock body (4) by the interior end face of filling in, even at least two pores (5) that are furnished with on the cock body wall, below pore, have the vertical bar seam (6) that is communicated with it, this seam disconnects the cock body base, and the outside turnup in the base of cock body wall is held packing ring (2)

   The end face of b, crown cap (1) has consent to lower recess in the depressed part center, and this consent periphery was close to interior plug cock body outer wall after interior plug was filled in consent

   C, packing ring (2) are annular arrangement, and thick outer thin in the whippy anchor ring, interior ring peripheral sleeve is blocked pore (5) on interior plug cock body outer wall.
