CA 1182779

ABSTRACT OF THE DISCLOSURE A safety closure comprises a cap having a pair of locking lugs which engage complimentarily disposed camming surfaces on the associated container and a plug or valve style liner disposed within the cap. The liner includes a generally planar disk having a hollow cylin- drical plug defining an outer surface having a compound taper and a conical projection spaced concentrically about said cylindrical plug. The liner extends into the finish of the container and seals it during axial translation of the closure corresponding to 180° or less rotation thereof. The liner, due to its sim- plicity, may be fabricated of material which exhibits resistance to the product within the container but which would otherwise be unsuitable or difficult to mold into the cap.
