Tamper indicating band for use in low rise cam-off application

Claim 2

A tamper indicating member for use with a closure removable by turning, said tamper indicating member in its as formed state being generally in the form of a sleeve and comprising an upper band and a lower band, rupturable bridges extending axially between and releasably interconnecting said upper band and said lower band, and means on said upper band and said lower band for axially separating said bands in response to rotation of said bands, said means including said upper band having securing means for attaching said upper band to a closure for rotation with the closure and said lower band having locking means for locking said lower and relative to a container to resist rotation of said lower band with said upper band when said upper hand is rotated, said locking means being in the form of a plurality of circumferentially spaced radially inwardly directed lugs formed on a radially inner surface of said lower band spaced above a lower end of said lower band, and each of said lugs having a circumferentially facing cam surface for urging said lower band axially away from said upper band in response to a rotary force in a closure releasing direction on said lower band.

Claim 3

A tamper indicating member according to claim 1 together with a retaining bead on said lower band for permanently retaining said lower band on a container, said retaining bead being separate and apart from said locking means.

Claim 4

A tamper indicating member according to claim 1 wherein each of said lugs has two of said circumferentially facing cam surfaces arranged axially one above the other, an upper one of said cam surfaces being operable to force said lower band axially away from said upper hand, and a lower one of said cam surfaces forming means for circumferentially positioning said lugs.

Claim 5

A tamper indicating member for use with a closure removable by turning, said tamper indicating member being generally in the form of a sleeve and comprising an upper band and a lower band, rupturable bridges extending axially between and releasably interconnecting said upper band and said lower band, and means on said upper band and said lower band for axially separating said bands and rupturing said bridges in response to relative rotation of said bands, said means including said upper band having securing means for attaching said upper band to a closure for rotation with the closure and said lower band having locking means for locking said lower band relative to a container to resist rotation of said lower band with said upper band when said upper band is rotated, together with a closure and a container neck finish, said closure having a sealed screw threaded connection with said neck finish, said tamper indicating member being coupled to said closure for rotation therewith, and said neck finish having stop means for engagement by said locking means, said locking means and said stop means having cooperable cam surfaces for urging said lower band axially downwardly in response to rotation of said lower band relative to said container neck finish, said lower band and said container neck finish having cooperating means disposed axially below and being separate and apart from said locking means and said stop means for retaining said lower band on said container neck finish after said closure and said upper band have been removed.

Claim 6

A tamper indicating member for use with a closure removable by turning, said tamper indicating member being generally in the form of a sleeve and comprising an upper band and a lower band, rupturable bridges extending axially between and releasably interconnecting said upper band and said lower band, and means on said upper band and said lower band for axially separating said bands and rupturing said bridges in response to relative rotation of said bands, said means including said upper band having securing means for attaching said upper band to a closure for rotation with the closure and said lower band having locking means for locking said lower band relative to a container to resist rotation of said lower band with said upper band when said upper band is rotated, together with a closure and a container neck finish, said closure having a sealed screw threaded connection with said neck finish, said tamper indicating member being coupled to said closure for rotation therewith, and said neck finish having stop means for engagement by said locking means, said locking means and said stop means having cooperable cam surfaces for urging said lower band axially downwardly in response to rotation of said lower band relative to said container neck finish, said lower band and said container neck finish having cooperating means disposed axially below and being separate and apart from said locking means and said stop means for retaining said lower band on said container neck finish after said closure and said upper band have been removed.

Claim 7

A tamper indicating member and closure and container neck finish assembly according to claim 4 wherein said closure and said tamper indicating means are of the press-on type and said locking means and said stop means have second coooperable cam surfaces for assuring movement of said locking means axially into overlapping relation to said stop means.

Claim 8

A tamper indicating member and closure and container neck finish assembly according to claim 4 wherein said stop means are in the form of axially extending and circumferentially spaced ribs projecting radially outwardly from said neck finish.

Claim 9

A tamper indicating member and closure and container neck finish assembly according to claim 6 wherein each of said ribs has an upper cam surface for engagement by said locking means for assuring movement of said locking means axially into overlapping relation witn said stop means when said closure and said tamper indicating member are applied.

Claim 10

A tamper indicating member and closure and container neck finish assembly according to claim 7 wherein each of said ribs also has a lower cam for engagement by said locking means during removal of said closure.

Claim 11

A tamper indicating member and closure and container neck finish assembly according to claim 8 wherein said locking means includes circumferentially spaced lugs, and each of said lugs has an upper cam surface for engaging a respective rib lower cam surface and a lower cam surface for engaging a respective rib upper cam surface.
