In this case, in a state in which the close contact portion (force par portion) 13 is removed, only the same can-drink cap 10 as in the first or second embodiment is mounted.
• the configuration of is as described above.
• the perforations 14 and 15 can be easily cut.
• the material of the contact portion (cover portion) 13 can be made hard.
• a material having a low elasticity at least after mounting when pulling up with the tongue piece 16, the middle part between both perforations 14 and 15 will be in close contact (cover part). This does not attract 13, so that the intermediate part can be easily removed.
• a shrink film having heat shrinkability can be used.
• the positional relationship between 13 and the canned beverage cap 10 is reversed.
• the contact portion (cover portion) 13 is covered from the upper surface of the canned beverage container 20, and the canned beverage cap 10 is covered thereon.
• This configuration is shown in FIG. In this case, the canned beverage can be opened by detaching the canned beverage cap 10 and then removing the close contact portion (cover portion) 13.
• the contact portion (cover portion) 13 is attached to the canned beverage container 20, first, the upper periphery of the canned beverage container 20 is covered with a heat-shrinkable material, so that the The attachment portion (cover portion) 13 can be covered in close contact with the outer shape of the canned beverage container 20.
• the contact portion (cover portion) 13 When covering the contact portion (cover portion) 13, it is also effective to use a hot-melt adhesive or the like to make the contact in a water-tight manner. Since the outer peripheral portion 12 of the can-drink cap 10 has elasticity, the can-drink container 20 is overlaid on the can-drink container 20 in which the above-mentioned close contact portion (cover portion) 13 is in close contact. When the can cap 10 is attached, the peripheral portion 12 of the can beverage cap 10 can be attached to the canned beverage container 20 by hanging it around the winding portion 21 of the can beverage container 20.
• the canned beverage container is usually discarded after drinking the contained beverage, but the canned beverage container made of metal is melted and reused as a metal material.
• a metal material Is polystyrene or polypropylene If it is composed of carbon dioxide, it is considered environmentally friendly because it is decomposed into water and carbon dioxide by incineration. Further, if the material of each of the above embodiments is made of a biodegradable material, it is useful to prevent generation of undecomposed dust.
