Easy-open bottle lid of the present utility model, main building makes the tight locking bottle mouth of bottle cap be convenient to the effect of opening again, and pad plays resistance to compression, leak free effect.Because gasket edge of the present utility model has air channel, as: sunflower shape, gear shape or through hole etc., dripping when moulding, plastics can organically inject the air channel of pad, the space of filling up between pad and the main cover side wall is combined closely pad and lid, strengthen the air-tightness of bottle cap, thereby prolonged the shelf-life of vapour-pressure type beverages such as beer, carbonated drink.When draw ring draws when opening, the gas in the bottle again can be by dripping to mould rapidly and release in the pad air channel, thereby deduct the pressure in the bottle rapidly, thereby be difficult for taking place the accident that bottle explosion is hurted sb.'s feelings.

Because the groove diameter in the pad is slightly less than internal diameter of the bottleneck and just falls in the bottleneck, can coincide with the bottleneck sealing, play the effect that increases airtightness of bottle cap; When this groove can make finger stretch into draw ring again simultaneously enough activity spaces are arranged, it is unrestricted to make finger catch on draw ring freely, conveniently draws and opens.If the bottom surface of pad further groove is a semisphere, because the pressure that sphere bears than the plane is big, when beverage in the bottle increased because of the vibration air pressure of transportation, pad still can stand intact, and has guaranteed the integraty of bottle cap; If the upper surface of pad further groove is the plane, then convenient printing word or figure in the above.

Because the flat top portion of main lid is smooth, so can meet the requirement of existing vapour-pressure type beverage can assembling production lines.

Because one of indentation line of the present utility model is extended down to the master from the draw ring coupling end and covers skirt ruffle lower end, another is extended down to main the lid the skirt ruffle from the draw ring coupling end, makes draw ring after drawing back, and draw ring does not break away from main lid, thus compliance with environmental protection requirements.

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