Definitions

• the present invention relates to a stopper integral type bottle cap made of soft and hard synthetic resin, and more particularly to a highly hermetically sealing synthetic resin made bottle cap capable of using without receiving any limitation for carbonated or non-carbonated beverage and which can be easily open the bottle cap without any opener and excellent in sealing effect.
• the cap can be taken off from a bottle only having to necessarily use an opener, and in the distributing course, since the cap is easily oxidized and corroded, not only it is bad in hygienic but also unpleasantness is given to a consumer in visual as well and hence value of commodity is fallen.
• cap in case of caps made of aluminum, it has advantage that the cap can be take off from the bottle without separate opener, but after the cap is taken off from the bottle, a portion that a cap is taken off from the bottle is very sharp and it has a worry about to hurt a finger, and the aluminum itself is expensive but its strength is weak whereby the sealing effect is reduced, therefore it has limitation in use that it is almost not in use for the carbonated beverage bottle and mainly can be used only for a cap of non-carbonated beverage or alcohol bottle and the like.
• the cap made of steel or aluminum as above is more than one hundred years in all in their oxidizing speed and is semi-permanent, therefore in case being thrown away around near place, they have been also a principal offender polluting a peripheral environment or soil.
• the present invention aims to solve all of problems in the steel made bottle cap or aluminum made bottle cap as described above, and it is a first object of the present invention to provide a bottle cap capable of easily taking off by one time action without separate opener, and second object is to provide a bottle cap excellent in sealing effect so as to be able to use commonly without any difference of carbonated beverage or non-carbonated beverage.
