Medicinal capsule with cap and body

Capsule has a cap with an inside upper circumferential slot and an inside lower raised member, and a body with outside circumferential slot for slidably locking the first slot during final locking. At least one connector on the outside surface of the second slot extends internally of the body to slidably lock with the cap raised member. The connector has a largerradiusof curvature than the member to form a space between them so that on preliminary locking of the cap and body the capsule is not deformed. The raised member and connector may both have a circular or a hexagonal configuration for easily interlocking with the space between them.
