PROBLEM TO BE SOLVED: To eliminate a need of a bottle opener for removing a crown cap by two-folding a rectangular nylon sheet, placing the two-fold nylon sheet on a mouth of a bottle, placing a plug of the cap over it, and putting a finger in a fold of the sheet to draw out and remove at the time of removal of the crown cap. SOLUTION: A nylon sheet 1 is cut into a rectangle, after this is two-folded, the two-fold sheet 1 is placed on a mouth of a bottle 3, and a plug is placed over it by a crown cap 2, thereby attaching the nylon sheet 1 to the mouth of the bottle 3. When the crown cap 2 is to be removed, a finger is put into a ring 4 of a fold of the nylon sheet 1, the cap 2 is drawn out together with the sheet 1. Thus a bottle opener is not needed when removing the crown cap 2. In addition, the finger is put into the ring 4 of the nylon sheet 1 and an end of the sheet 1 is held for pulling out, thereby preventing the cap 2 from blowing. In addition, the finger is put into the ring 4, thereby easily carrying a plurality of bottles.
