Abstract

The utility model relates to an explosion-proof bottle cap for a glass beer bottle, which is composed of an outer cap, a sealing gasket and a pressure reducing valve on which a groove is arranged, and a hole is arranged on the groove and opened onto a bottle mouth. The groove is sealed by a rubber sealing ring, and an air exhaust through hole is arranged on the outer cap. A pressure releasing device is arranged in the outer cap by the explosion-proof bottle cap for the glass beer bottle, a bottle bursting event can be effectively prevented from happening under the condition that the existing cap sealing technology is not changed, and quality of beer can be ensured not to be changed. The utility model has the advantages of simple structure and easy operation.

Description

The beer bottle explosion-proof bottle cap

The utility model belongs to a kind of container cover, relates in particular to a kind of beer bottle bottle cap.

At present, the domestic beer bottle bottle cap that is using is tin-plate and makes, the Gai Kou outer is wrinkle, packing seal is arranged in the lid, when filling-in and closing bottle by applying cap, shrink wrinkle garden week with mechanical means, make the inwall and the bottleneck outer wall of lid fastening, and the sealing state of interior packing seal of maintenance lid and bottleneck horizontal surface, secluding air enters, and reaches the purpose of guaranteeing the quality.Because beer is carbonated beverage, when it was subjected to influencing of temperature rise, concussion etc., its in-to-in volume will expand, and caused pressure of the inside of a bottle to raise, and when interior pressure surpasses the compressive strength of bottle, will blast.In recent years the bottle explosion of the Fa Shenging incident of the hurting sb.'s feelings end that appears in the newspapers repeatly, but together blast bottle cap can not washed open, obviously bottle cap and the gripping power of bottleneck are greater than the pressure of the generation of expanding.Though country forces to carry out the Type B beer bottle now, its objective is the compressive resistance that will improve bottle itself, yet from practice, the use of Type B bottle does not fundamentally reduce the generation of bottle explosion incident.In essence, this exactly band pressure vessel does not have suitable pressure release approach, in discloseder patent applications, many explosion-proof bottle caps are also arranged, and mostly this type of application is to set up pressure relief device outside bottle cap, because these technical schemes are not set about from the filling process of Beer Production producer, do not take into account yet and guarantee the quality and the needs of link such as transportation, therefore, all be difficult for implementing, so still continue to use traditional bottle cap now.

The purpose of this utility model is to disclose a kind of beer bottle explosion-proof bottle cap, and it can prevent the generation of bottle explosion incident effectively, can guarantee quality of beer again, and is easy to implement.

For achieving the above object, the employing technical scheme is as follows: this beer bottle explosion-proof bottle cap, contain enclosing cover and packing seal, packing seal is positioned at enclosing cover, particularly between enclosing cover and the packing seal reducing valve is arranged, and reducing valve is flat Cylinder, side around Cylinder is fluted, have through hole to lead to the valve body bottom on the groove, have on the packing seal and the corresponding hole of valve body base apertures, sealing rubber ring places on the annular recess.

In addition, be provided with through hole in the side of enclosing cover.

Below in conjunction with the embodiment accompanying drawing the utility model is described in detail.

Fig. 1 is the structural representation of beer bottle bottle cap.

By Fig. 1, the enclosing cover 1 of beer bottle explosion-proof bottle cap is identical with the enclosing cover of existing bottle cap, is to be made by tin-plate also, and the opening edge of enclosing cover is along wrinkle 11 are arranged.Packing seal 2 and reducing valve 3 are arranged in the inside of enclosing cover 1, and reducing valve 3 is between the inner plane and packing seal 2 of enclosing cover 1, and reducing valve 3 is flat Cylinder shape, around the side of Cylinder fluted 31, porose 32 lead to valve body bottom on the groove 31, and porose 21 on packing seal 2, hole 32 communicates with hole 21.On groove 31, be provided with the sealing rubber ring 33 of ring-type, in order to seal bore 32.Also be provided with a through hole 12 on the side of enclosing cover 1.Direction shown in the arrow is after the bottle inner volume expands among the figure, the path of exhaust.

This explosion-proof bottle cap is the same with existing bottle cap when installing, the bottle cap end opening places on the glass bottle opening, shrink the wrinkle of bottle cap lower edge with machinery, after the capping, packing seal 2 contacts with bottleneck, reducing valve 3 is clamped between enclosing cover 1 and the packing seal 2, because hole 32 sealed rubber ring 33 sealings, beer at this moment is in sealing state.When the influence that is subjected to external conditions, when the bottle inner volume expands, expanding the pressure that produces will be along direction shown in the figure, sealing rubber ring 33 is outwards backed down, the depressurization state, carry out pressure release, a part is discharged by the packing seal 2 and the gap of enclosing cover inwall, and another part is discharged by the through hole on the enclosing cover side 12.After the pressure release, along with reducing of pressure of the inside of a bottle, sealing rubber ring 33 can shrink under the elastic force effect, and sealing is continued in hole 32, so just can guarantee that the quality of beer is constant substantially.

The utility model compared with prior art has the following advantages:

1, is provided with pressure relief device, therefore can effectively prevents the generation of bottle explosion event, ensured The personal safety of drinking person.

2, can recover sealing state again after the pressure release, can guarantee that the quality of beer is substantially constant.

3, need not change the existing filling and capping technology of Beer Brewage producer, simple in structure, be easy to Implement, have more practicality.

Claims

1, a kind of beer bottle explosion-proof bottle cap, contain enclosing cover and packing seal, packing seal is positioned at enclosing cover, it is characterized in that between enclosing cover and the packing seal reducing valve being arranged, reducing valve is flat Cylinder, and is fluted around the side of Cylinder, the porose valve body bottom of leading on the groove, have on the packing seal and the corresponding hole of valve body base apertures, sealing rubber ring places on the annular recess.

2. beer bottle explosion-proof bottle cap as claimed in claim 1 is characterized in that there is through hole the side of enclosing cover.
