Abstract
An improved child resistant safety closure and container assembly of the type including a cap having an end wall with a skirt projecting therefrom and bayonet locking means projecting from the inner wall of the skirt for engagement with complementary bayonet locking means on the container by combined axial and rotary motion of the cap relative to the container. A combined spring and sealing member is carried by the cap, which, when the cap is applied to the container, resiliently maintains the cap and container in locked engagement, and also provides a moisture proof seal for the contents of the container. The spring and sealing member comprises a one-piece plastic body having a sealing portion and a biasing portion, the sealing portion including a radially projecting, annular sealing flange for overlying the rim of the container, and an axially extending sealing flange for engaging the inner surface of the mouth of the container. The radially extending sealing flange has an outer peripheral edge that overlies the bayonet locking means of the cap to prevent axial separation of the spring and sealing member from the cap, the spring and sealing member being otherwise unconnected with the cap. The spring and sealing member includes a dome-like biasing portion that projects integrally from the inner periphery of the radially projecting sealing flange which, when the cap is applied to the container, flexes and bows outwardly in a manner to apply a force on the sealing portion having a substantial axial component to press the sealing portion into tight engagement with the rim of the container, and also the radial component to press the axially extending sealing flange into tight engagement with the inner surface of the mouth of the container.
