PROBLEM TO BE SOLVED: To prevent erroneous operation in recycling a container that a consumer or the like erroneously pulls a holding piece by bringing a coin into contact from the outside of a remaining part of a weakened part provided on a lid fitted into a mouth of the container and pushing it inward to break the remaining part to enable a holding part to be held. SOLUTION: An inner lid 5 which is a synthetic resin lid to be fitted into a mouth 2 of a container 1 comprises a break line 20 formed on a mouth wall 4 which is torn by pulling a tear-off member 21 and a through port formed therein. When the lid 5 is to be removed from the container in collecting such containers 1, a coin is brought into contact from the outside of a remaining part 15 of a weakened part, and it is pushed inward to break the remaining part 15 to enable a holding part 11 to be held. With the holding part 11 held, and the weakened part is broken to loosen pressure contact between a cylinder 3 and the mouth 2, so that the lid 5 can be easily removed from the mouth 2. Thus since a holding piece is not protruding outside the lid, erroneous operation that a consumer or the like erroneously pulls the holding piece can be prevented. |
