Abstract
A child resistant safety closure and container assembly of the type including a cap having locking lugs projecting from its skirt for engagement with complementary bayonet locking elements on the container. A combined spring and sealing member is carried by the cap to resiliently maintain the cap and container in locked engagement, and provide a moisture proof seal. The spring and sealing member includes a plunger having a cylindrical base portion concentric with a cylindrical sealing wall. A plurality of radial stiffening members extend between the base portion and the inner end of the cylindrical sealing wall. In one embodiment, the stiffening members are in the form of ribs molded integrally to the side wall. In another embodiment, the stiffening members are in the form of flutes molded into the side wall.
