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.

A container closure comprising a top panel piece molded of plastic, a dispensing opening formed through said panel piece, a flap molded integrally with said panel piece along a hinge line and swingable upwardly and downwardly about said hinge line and relative to said panel piece between open and closed positions with respect to said dispensing opening, said flap having a front edge extending generally parallel to said hinge line, an elongated plastic strip piece extending alongside and spaced forwardly from the front edge of said flap and overlying said panel piece when said flap is in said closed position, tearable webs molded integrally with and spaced along said strip piece and the front edge of said flap and extending between the two, upright openings formed through one of said pieces, upright plastic pins molded integrally with the other of said pieces and extending into said openings, and means on said pins for normally holding said strip piece and said flap downwardly against said panel piece but sufficiently weak to tear in response to an upwardly lifting force being applied to one end portion of said strip piece whereby said strip piece may be lifted upwardly from said panel piece and torn away from the front edge of said flap at said webs thereby to enable the flap to be swung upwardly to its open position.
