ABSTRACT:
A container and closure assembly wherein the container is adapted to be initially closed by a sealing means such as a vacuum disc. The closure has two positions of attachment to a bead encircling the container. In the first position of attachment, which accommodates the aforementioned sealing means, the container bead is engaged in an annular notch located in the inside wall of a closure skirt. The notch weakens the skirt so as to allow a distal end of the skirt to be torn from a remaining portion of the closure to free the remaining portion of the closure from attachment to the container bead. This exposes the sealing means so as to allow a removal thereof and access to the contents of the container. The remaining portion of the closure is then reattachable to the container bead at a second position of attachment rendered accessible by removal of the sealing means for reclosure of the container. In a first embodiment, the closure has retention ribs permitting preassembly of the sealing means to the closure. In a modification, the retention means comprises an inwardly directed skirt bead sized to retain the sealing means.
