ABSTRACT:
A dispensing closure having a base cap with a top containing a dispensing orifice and a skirt adapted to be attached to a container so that dispensing of the container contents can take place only through the cap orifice. The orifice is sealed with an integrally molded removable disc having a spiral weakening groove which defines a tear strip. Lifting a pull ring attached to the tear strip removes the sealing disc as a spiral strip so that any attempt to hide a previous partial opening by pushing the lifted portion of the strip back in the plane of the disc will be easily detected. A lid attached to the base cap provides easy access to the seal for detecting tampering and removal for use as well as acting to close the orifice after removal of the sealing disc.
