Abstract

A safety dispensing cap for fluid containers is disclosed. The cap features a tubular discharge member, a tubular closing member for attaining a rotating overlying removable fit on the discharge member and an internal latching assembly which is activated or deactivated by rotation of the tubular closing member about the tubular discharge member. The latching assembly comprises an inwardly extending latching lug on the tubular closing member and an outwardly extending latching lug on the tubular discharge member. In the locked position, the discharge latching lug will overlie the closing latching lug thus preventing removal of the closing member from the discharge member. Unlatching of the two members is achieved by a rotation of the closing member until the closing member latching lug is no longer underneath the discharge member closing lug. An indexing assembly can also be provided which will hold the unlocked position.
