Abstract
A container cap assembly comprises a one-piece integrally molded annular cap body hinged to a one-piece integrally molded lid. The cap body has a lower section with internal female threads for cooperation with matching male threads on a container and an annular upwardly extending flange. The lid has a downwardly extending flange. The flanges have interlocking sealing surfaces which extend outwardly at an acute angle to the vertical so that the lid flange will snap over the cap body flange in the closing mode and retain the lid in a closed and sealed position relative to the cap body until the lid is forced upwardly.
