Abstract

A twist-type closure for bottles. The closure includes an inner member with a disk-like portion and a depending peripheral lip, which is adapted on the interior to match the particular closure provision of the bottle. Projecting upward from the disk portion is a neck terminating in a closed flange having, in one embodiment, a slightly greater diameter than the neck. An outer member generally surrounds, and is rotatable with respect to, the inner member. This outer member also has a disk-like portion and a depending peripheral lip. The outer member has a central opening to permit receiving the flange therethrough to assemble the closure. Between the disk portions of the inner and outer members is a biasing member to normally maintain these portions separated but allow movement toward each other when pressure is applied to the outer member. Also, between the inner and outer members are cooperating opening tabs which, when aligned and moved into engagement by pressure upon the outer member, permit the outer and inner members to be turned counter-clockwise in unison to effect removal of the closure. Arrow indicia on the top surfaces of the outer and inner members indicate the proper alignment of the opening tabs. Cooperating closure tab means carried by the members effect the clockwise turning of the components in unison to effect tightening of the closure. Optionally, numerals are equally spaced around the opening in the outer member to indicate the time of the next dosage of a medicine, for example.
