ABSTRACT:
A hard gelatin capsule, especially for medicaments, having a cylindrical body and a cylindrical cap that telescopes over the open end of the body in which the interior surface of the cap, which overlaps the body, is provided with toothlike projections spaced around the circumference thereof to lock the body and cap against relative axial and rotational movement. In a preferred form of the invention the projections have gently-sloping side walls in both the lateral (circumferential) and longitudinal (axial) directions, which facilitate removing the cap from the dipping pin on which it is formed.
