Abstract
A container closure is provided for initially hermetically sealing a container and for thereafter reclosing the container. The closure includes a top wall with a hinged flap portion and a locking segment for engaging and retaining the flap when it is depressed downwardly to reclose the container. A portion of the peripheral edge of the flap is initially defined by a frangible seal. Once the frangible seal has been ruptured, the flap can be pivoted about its hinge to open the container and provide access to its contents. Between uses, the flap is depressed downwardly past a flange which projects from the locking wall. The flange holds the flap closed until a positive opening force is applied to the flap.
