ABSTRACT:
A Dose reminder type, two piece closure which may be attached to a container by conventional capping Machines. An inner cap member is formed with a circular top panel having a depending skirt integrally molded therewith. The depending skirt is threaded on its interior surface for engagement with a conventional threaded container finish. A flanged portion bearing indicia is integrally formed, projecting radially outwardly from the base of the depending skirt. An outer cap member is also formed with a circular top panel and an integral depending skirt ending at the base in a series of symmetrical dyhedral configurations. The bias of the dyhedral contour matches evenly with a like shaped track integrally formed around the inner diameter of the aforementioned inner cap member flange. This arrangement permits positive engagement of the two member closure for removal from a container. However, when the closure is fully reengaged on the container, the outer member containing an indicator means can be advanced to the next indexing point with a slight pressure continuing in the engagement direction.
