When air pressure in a bottle reaches a definite value, the sealing gasket and the pull ring are pushed by the air pressure, air is released from the groove hole, and thus the crown-shaped easy-pull explosion proof bottle cap of the utility model is easier to discharge pressure and safer to ensure a consumer's safety.

Description

The easy-to-draw explosion-proof bottle cap of crown type

The utility model relates to a kind of crown easy-to-draw explosion-proof bottle cap.

People drink various bottled light sparkling wines in daily life, and are often worried for uncork during carbonated drink, have bottle opener also all right, otherwise have to tooth, table limit, the chair back, use uncertain can opening entirely along wall, or bottleneck is also made a mess of; Bottled in addition light sparkling wine all has certain air pressure in the bottle of carbonated drink, owing to rocking what is heard is arranged when making pressure rises cause thing that bottle blasts; Or once bottle cap is knocked and your are spurted out, spattered to light sparkling wine, carbonated drink in the bottle all over the body.The Chinese patent communique discloses a kind of crown easy-to-draw explosion-proof bottle cap for this reason, and it is made up of lid, pad and packing seal from top to bottom; One draw ring is arranged on the lid, and it is two indentations that do not cut that draw ring connects with lid; Recessed in the middle of the pad, correspondence has a breach on the periphery under two indentations.When the bottle internal gas pressure reaches certain value, air pressure will back down draw ring and from the breach venting, guarantee consumer safety like this.But the crown easy-to-draw explosion-proof bottle cap of this kind in use finds, the lid corresponding position is flat because pad is jagged, makes seal gasket thicker in indentation, there, to a certain extent overslaugh air pressure draw ring is backed down exhaust, making begins to rehearse presses and has some setbacks.

The purpose of this utility model, just provide a kind ofly can effectively overcome defective that seal gasket thickens in indentation, there, be easier to row pressure, safer crown easy-to-draw explosion-proof bottle cap.

For achieving the above object, the utility model can be taked following technical measures.

The crown easy-to-draw explosion-proof bottle cap of the utility model power comprises from top to bottom lid, pad and packing seal, on the crown lid draw ring is arranged, and it is two indentations that do not cut that draw ring connects with lid; Recessed in the middle of the pad of garden shape, it is characterized in that: in two indentations that do not cut of described draw ring, a low groove is arranged; Corresponding position at pad has slotted eye; Low groove drops in the slotted eye.

Owing to adopted abovementioned technology, the low groove of draw ring protrudes and drops in the slotted eye of pad on the lid, sealant is more even when making sealing, can not become thick especially at the slotted eye place, guaranteed when the overproof and people of pressure of the inside of a bottle shake bottle, air pressure in the bottle is easy to drain, and is unlikely the danger that produces blast.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the cross-sectional schematic of the utility model embodiment.

Fig. 2 is the attached scheme drawing of looking of lid.

Fig. 3 is along the A-A line cross-sectional schematic of Fig. 2.

Fig. 4 is the front view of pad.

Fig. 5 is the attached view of pad.

Fig. 6 is the main pseudosection of packing seal.

Fig. 7 is the attached view of packing seal.

Can see that from Fig. 1 to Fig. 7 the crown easy-to-draw explosion-proof bottle cap of the utility model power comprises from top to bottom lid 1, pad 2 and packing seal 3, and draw ring 4 is arranged on the crown lid, it is two indentations 5 that do not cut that draw ring connects with lid; Recessed in the middle of the pad of garden shape, in two indentations that do not cut of draw ring, a low groove 7 is arranged; Have slotted eye 8 in the corresponding position of pad; Low groove just in time drops in the slotted eye.So, sealant can not become thick especially but relatively evenly at the slotted eye place, and when the bottle internal gas pressure reached certain value, air pressure backed down packing seal, draw ring and exits from slotted eye; When opening bottle cap, with having pulled draw ring, can be easy to draw ring and lid are separated, make bottle cap break away from bottleneck, do not damage bottle, make the crown easy-to-draw explosion-proof bottle cap of the utility model power be easier to row pressure, safer, guarantee consumer safety.
