Abstract
A one piece, resilient, integrally molded container cap consisting of a rotor member, fixed member and a frangible connecting tab. The rotor member has a closed portion and an opening portion, and the fixed member has a closed portion and a sifting and pouring opening. As manufactured, the rotor member is attached to the fixed member by a frangible connecting tab. When desired to attach the container cap to a container, the rotor member is pivoted along the frangible connecting tab to be axially displaced from the fixed member. The rotor member is then pushed down on the fixed member, the members engaging each other by complementary locking surfaces. This action insures that the closed portions of the rotor and fixed members are aligned to prevent the contents of the container from undesired escape and also effects a tight, secure fit of the rotor member to the fixed member. When it is desired to dispense the contents of the container, the rotor member is rotated to sever the frangible connecting tab, and the opening portions of the rotor and fixed members are aligned thus allowing dispensing of the contents of the container.
