Abstract

A closure for bottles having twist-type closure provision. The closure includes an inner member with a disk-like portion and a depending peripheral lip having an interior adapted to match the particular closure provision of the bottle. A neck projecting from the disk portion terminates in a closed flange having a slightly greater diameter than the neck. An outer member, rotatable with respect to the inner member, has a disk-like portion and a depending peripheral lip equally spaced from that of the inner member and has a central opening of a diameter intermediate that of the neck and the flange to permit snapping the flange through the opening to assemble the closure. A spring between the disk portions of the members normally maintain these portions separated but allows movement toward each other when pressure is applied to the outer member. Cooperating opening tabs between the members, when aligned and engaged by pressure upon the outer member, permit the outer member and the inner member to be turned counterclockwise in unison to effect removal of the closure from the bottle. Arrow indicia on the top surfaces of the flange and the outer member indicate the proper alignment of the opening tabs. Cooperating closure tabs carried by the members effect the clockwise turning of the components is unison to tighten the closure. Optionally, numerals are equally spaced about the opening in the outer member to provide information as to the time of the next dosage of a medicine, for example.
