Abstract

A child proof medication bottle including a female, interiorly threaded opening adapted for dispensing medication in pill form or similar use, provided with a male, externally threaded cap, inserted into the female opening. On insertion, the male cap or plug is received within the opening to a depth wherein only a hemispherical projection is exposed outside the confines of the bottle. This smooth hemispherical projection lacks the necessary grasping surfaces for withdrawal thereof and is thus rendered child proof. The bottom end of the bottle is similarly shaped in the form of a hemisphere adapted for receipt in the interior of the cylindrical key structure provided with a flat end for upright support and including two key elements insertable into corresponding slots formed in the hemispherical surface of the cap. Thus the cylindrical key structure may be utilized to open providing a reminder to the user to return the key to its stored position.
