ABSTRACT:
An end closure assembly for a dispensing container and the method of assembly. A cover mounted on the container includes a central opening and a radially spaced dispensing passageway. A rotor overlies the cover and is rotatable about a central, generally columnar, hub positioned within a central orifice of the rotor such that a dispensing passageway through the rotor can be rotated into and out of registry with the cover dispensing passageway to thereby open and close the container. The hub includes an annular, radially outward extending flange which overlies the rotor and holds the rotor against the cover. An annular gripping lip integral with the cover permits downward insertion of the hub into the cover orifice during assembly yet inhibits removal of the hub after assembly. If the assembly is tampered with by attempting to remove the hub from the cover orifice or by removing the rotor from beneath the hub flange, it will be difficult to replace the rotor or hub without the assembly showing evidence of the tampering. An efficient method of assembling the end closure includes forming the rotor and hub as a one piece article of manufacture connected by bridging material which breaks and separates the rotor and hub during assembly. The method is not only more economical but also allows a design formed into the rotor and hub to be in proper alignment immediately after assembly.
