ABSTRACT:
Three hinged flaps of a plastic container closure are molded while in open positions and, during molding of the flaps, an elongated tear-away strip is formed along the front edges of the flaps and is integrally connected to the flaps by tearable webs. After the newly molded flaps have first been closed, the strip is anchored releasably to the top panel of the closure and prevents the flaps from opening during shipment of the container, the strip also serving as a visual indicator that the seal of the closure is intact. The closure is opened by lifting and pulling on the strip to tear the latter completely away from the top panel and the flaps and to free the flaps for swinging to open positions. The absence of the strip or the presence of a partially torn strip indicates that tampering has occurred and that the seal may not be intact.
