BOTTLE CLOSURE

摘要

The carbonated water bottle hull consists of the tap(4) coming out the content through the tap inside hole(6) and the flexible part(7) being easily deformed by an applied force. The tube shaped revetment(8) even higher than the flexible part around the it and the tube holder(11) at the flexible part's lower part of center are formed. The seal exit channel(9) is fixed to the formed tube holder. When the carbonated water bottle cap is placed to the bottle, the tap end is cut along the cutting slot and opens, but high pressure builds up inside the bottle due to the carbon gas. Therefore the content will not flows out since the seal is pressed towards the tap inside hole and sticks to it. When the flexible part is deformed because force is applied to the hull flexible part, the content inside the bottle flows out through the seal exit channel due to the high inside pressure since the seal falls from the tap inside hole.
