Claims
- 1. A tamper-indicating plastic closure for a container having an annular locking ring, comprising:
- a closure cap having a top wall portion, and an annular skirt portion depending from said top wall portion; and
- an annular pilfer band having an axial length, said pilfer band being partially detachably connected to said skirt portion by frangible bridge means, said pilfer band including engagement means comprising a plurality of circumferentially spaced, inwardly extending flexible projections each movable about a respective horizontal axis, said flexible projections of said engagement means being engageable with said container locking ring during removal of said closure from said container for fracturing said frangible bridge means detachably connecting said pilfer band to said skirt portion, said pilfer band further including a connector portion connecting said pilfer band to said skirt portion after fracture of said frangible bridge means,
- said pilfer band including at least one fracturable means for splitting said pilfer band, said fracturable means fracturing upon removal of said closure from said container and fracture of said frangible bridge means, said fracturable means comprising at least one axially extending score formed in said pilfer band and extending radially of said closure through one of said flexible projections.
- 2. A tamper-indicating plastic closure in accordance with claim 1, wherein
- said pilfer band includes an annular interference bead positioned generally beneath said flexible projections, said score extending radially of said closure at least partially through said interference bead.
- 3. A tamper-indicating plastic closure in accordance with claim 1, wherein
- said fracturable means comprises a pair of circumferentially spaced axially offset scores formed in said pilfer band one of which comprises said score extending through one of said flexible projections, said pair of scores each extending only partially along the axial length of said band and defining a fracturable residual portion of said fracturable means generally between said pair of scores.
- 4. A tamper-indicating plastic closure in accordance with claim 1, wherein
- said fracturable means of said pilfer band is substantially diametrically opposed to said connector portion.
- 5. A tamper-indicating plastic closure for a container having an annular locking ring, comprising:
- a closure cap having a top wall portion, and a depending annular skirt portion depending from said top wall portion and including an internal thread formation for engagement with a like thread formation on said container; and
- an annular pilfer band having an axial length, said pilfer band being distinguished from said skirt portion by a circumferentially extending score line, and partially detachably connected to said skirt portion by a plurality of circumferentially spaced frangible bridges, said pilfer band including an annular band portion, and a plurality of circumferentially spaced projections extending inwardly from said annular band portion for movement about respective horizontal axes, said pilfer band further including an annular interference bead positioned generally beneath said projections,
- said projections being engageable with said container locking ring during removal of said closure from said container for fracturing said frangible bridges,
- said pilfer band including a connector portion connecting said pilfer band to said skirt portion after fracture of said frangible bridges,
- said pilfer band including at least one fracturable means for splitting said pilfer band, said fracturable means fracturing upon removal of said closure from said container and fracture of said frangible bridges, said fracturable means comprising a fracturable residual portion extending between a pair of circumferentially spaced and axially offset scores each extending only partially along the axial length of said band, one of which scores extends downwardly from said score line and the other of which extends upwardly from a lower free edge of said annular band portion of said pilfer band, one of said pair of scores extending radially of said closure at least partially through one of said flexible projections of said pilfer band.
- 6. A tamper-indicating plastic closure in accordance with claim 5, wherein
- said one of said pair of scores extends radially of said closure through one of said projections and through said interference bead.
- 7. A tamper-indicating plastic closure in accordance with claim 6, wherein
- said one of said scores has a greater axial extent than the other one of said scores.
