In the present invention to solve the unsolved problems of the conventional technique, a plurality of grooves (24) are formed on the lower end (22) of a cap to be adhered to the outer lower edge part (4) of a bottle inlet by a constant length vertically. A part formed with the grooves (24) is shrunk and combined when the bottle cap is combined in the bottle mouth, and the part formed with the same is extended or incised when separating the bottle cap from the bottle mouth by opening the upper part of the bottle cap. Therefore, an elastomer stopper is sealed strongly enough like the conventional technique for sealing the bottle, and the bottle and the cap can be easily separated by pushing the upper portion with less power than the conventional technique when separating the cap. |
