Abstract
A container cap locking a plug member to a mouth by a locking member and capable of being removed from the mouth together with the plug member by repositioning a holder member. The locking member is covered on the container mouth so as to hold the plug and the holder member is fitted to the outer peripheral sides of a plurality of locking pieces of the locking member. In each locking piece, an upper side part is connected to a lower side part through a thin-walled bending part. The upper side part is locked to the rubber plug from the lower side with the holder member on the outer peripheral side thereof. The lower side part is locked to the container mouth from the lower side by the holder member. Locking projected parts prevent the lower end of the holder member from coming out of the upper side part.
