PROBLEM TO BE SOLVED: To prevent occurrence of refuse which causes an environmental pollution on disposal of a bottle after use by a method wherein a cap-like member having an internal thread to be screwed down onto a mouth of a synthetic resin bottle and a hook member connected to the cap-like member are provided. SOLUTION: A hook member 3 is formed of a synthetic resin, being integral with a cap-like member 2 which has an internal thread 21 to be screwed down onto a mouth of a PET bottle. The standard of the internal thread 21 is made, corresponding to the standard of the thread at the mouth of the PET bottle. The hook member 3 is constructed of a hook-shaped member 31 and an elastic piece 32. With the elastic piece 32 pushed and deformed elastically, a gap is made against the hook-shaped member 31, and thereby the hook member 3 can be easily hung on. The hook-shaped member 31 is formed in an upside-down J shape. Since the section of the hook-shaped member 31 is formed in an H shape, the strength is heightened. Therefore, it becomes unnecessary for a synthetic resin bottle to be put on disposal after use, and the bottle can be reused, with the hook provided, for assortment and storage of small items. |
