Abstract: A tamper-indicating closure and package and method of making comprising a one-piece molded closure of plastic which threads onto a container such that when the closure is unthreaded, a tamper-indicating band becomes separated from the lower end of the closure skirt. The tamper-indicating band is joined to the closure along a weakened frangible line. A flexible wall is formed within the band and extends axially toward the base of the closure. The wall has a free edge which has circumferentially flexible spaced flexible wall portions defining pleats or scallops that extend radially inwardly. When the closure is applied to the container, the circumferentially extending wall portions flex radially outwardly over the annular bead on the container and then radially inwardly beneath the annular bead. When the closure is unthreaded, the upper edges of the circumferentially spaced circumferential wall portions engage the underside of the bead and cause the band to sever along the weakened line.

Abstract: This relates to a tamper indicating cap which includes a conventional closure of the threaded type. The closure is provided with an injection molded member which includes an inner ring that overlies and is bonded to an end panel of the conventional closure and an outer ring which is telescoped over and extends beyond a skirt of the conventional closure. The inner ring is joined to the outer ring by a first set of breakable bridges and a second set of bridges in the form of diagonal links. When the outer ring is turned in a cap removing direction, the two rings move relative to one another sufficiently to cause rupture of the first set of ribs to indicate tampering. The diagonal links then transmit cap removal torque to the center ring and from the center ring to the shell of the conventional closure.

Abstract: As opening/closing device to be provided at a mouth of a container such as a paper container, a bottle, a can, etc., in which a lid is provided via a hinge on the inside of a cylindrical pouring mouth made of synthetic resin and a gap space is formed between the pouring mouth and the lid. A metallic film consisting of a metal foil having synthetic resin layers coated on its both surfaces is bonded so as to straddle both the upper surface of the lid and the upper surface of the pouring mouth. Opening of the lid is effected by peeling of the metallic film, and upon closing the lid, the metallic film is pressed from its outer surface so that it may be stuffed in the gap space between the lid and the pouring mouth. Upon making the opening/closing device, an annular protrusion is formed on the top end surface of the pouring mouth, the metallic film is bonded to this annular protrusion and the lid so that the metallic film may be easily peeled off.
