  • Patent number: 5226539
    Abstract: A pill container has a lower part with eight compartments, and an upper part that rotates on the lower part. The compartments are side-by-side in a circular arrangement, and each normally contains a daily allotment of pills. The upper part carries a door, and a detent mechanism ensures that the door locates successively over each compartments. A button can be depressed to release a locking mechanism normally securing the door. A mechanical linkage simultaneously transforms axial displacement of the button into an indexing of a numbered plate relative to an indicator, effectively counting the number of times the door has been opened to remove pills. This provides an indication of the number of pills consumed. Manual rotation of the upper part to locate over a new compartment automatically resets the count. Alternatively, an electronic counter and display with appropriate switches may be used.
