A tamper-indicating plastic closure construction is disclosed which includes an annular pilfer band which depends from an annular skirt portion of the closure. The pilfer band is partially detachably connected to the skirt portion by frangible ribs, and remains connected to the skirt portion attendant to removal of the closure from a container. To facilitate such removal, the pilfer band includes a fracturable portion defined by a pair of vertically spaced, vertical scores. In order to substantially prevent any propagation of the upper one of the vertical scores, another score is formed in intersecting relation thereto. Consistent manufacture and reliable performance are further promoted by the formation of a stabilizing score in operative association with the fracturable portion of the pilfer band.

Scoring arrangement for a tamper-indicating plastic closure

A tamper-indicating plastic closure construction is disclosed which includes an annular pilfer band which depends from an annular skirt portion of the closure. The pilfer band is partially detachably connected to the skirt portion by frangible ribs, and remains connected to the skirt portion attendant to removal of the closure from a container. To facilitate such removal, the pilfer band includes a fracturable portion. Consistent and reliable performance are promoted by the formation of a stabilizing score in operative association with the fracturable portion of the pilfer band. A method of forming the closure is also disclosed, including the provision of movable scoring blades for effecting scoring of the closure to facilitate high-speed manufacture.

Tamper-indicating plastic closure

A composite closure for a container is disclosed which includes an outer plastic cap and an inner plastic sealing liner. Formation and retention of the sealing liner within the cap is promoted by the provision of an annular liner-retaining lip which extends inwardly from a skirt portion of a cap in closely spaced relation to its top wall portion, and thus defines an annular recess therewith, Liner retention is further enhanced by the provision of a plurality of circumferentially spaced first liner-engaging projections which are arranged in adjacent pairs within the annular recess of the cap in converging relation with each other. Liner retention is further enhanced by the preferred provision of a plurality of second circumferentially spaced liner-engaging projections extending integrally from the top wall portion of the cap in operative association with the converging adjacent pairs of the first projections.
