1. A pill dispenser which comprises:
- a pair of relatively rotatable members for sequentially dispensing a different pill in response to the relative rotation of one member to each of a plurality of different angular positions relative to the other member; and
means for normally preventing relative rotation between said members in both rotational directions and for enabling said relative rotational movement only in response to axial forces applied to said members in opposite axial directions, said means preventing rotation comprising a spring biasing said members toward each other, whereby axial forces applied to said members in opposite axial directions can overcome enough of said spring bias to enable relative rotational movement of said members.

Abstract
A child-proof pill dispenser sealed against contamination is disclosed in the illustrative embodiments. The dispenser includes a pair of relatively rotatable members, which are normally prevented from rotation by axially biased teeth. A force applied against the bias disengages the teeth and permits the members to rotate. Rotation of the members opens a passage for automatic delivery of a pill. The pill is delivered from a storage compartment through an encircled passage into one of the hands required for operating the dispenser. The dispenser has a compression seal between the members for preventing contamination.

10. A pill dispenser carrying a plurality of pills, which comprises:
- a pair of relatively rotatable members for sequentially dispensing a different pill in response to the relative rotation of one member to each of a plurality of different angular positions relative to the other member;
means for normally preventing relative rotation between said members in both rotational directions and for enabling said relative rotational movement only in response to axial forces applied to said members in opposite axial directions, said means preventing rotation comprising a spring biasing said members toward each other, whereby axial forces applied to said members in opposite axial directions can overcome enough of spring bias to enable relative rotational movement of said members;
one of said members being a ring defining a plurality of recesses in one surface thereof, each recess being adapted to receive one of said pills, and the other of said members having a surface overlapping said one surface;
each of said pills being disc-shaped and with the peripheral surface of each disc being supported on a surface underlying a respective recess.
