Abstract
Abstract A container for a tamper-evident closure comprising a cap portion of cuplike form, and a tamper-evident band connected to the cap portion by fracturable means. The tamper-evident band comprises retaining means projecting radially inwardly and the container comprises a neck finish portion having a discharge opening and closure engagement means which mates with the container engagement means of the cap portion so that the closure can be applied and removed from the container. A first projection is spaced axially below the closure engagement means on the container neck finish and a second projection is spaced axially below the first projection closely adjacent thereto. A radially inwardly directed circumferentially extending groove has a smallest diameter less than the largest diameter of the first and second projections and is cooperatively associated with the retaining means on the tamper-evident band so that upon initial removal, the retaining means on the tamper-evident band engages in the groove to support at least a portion of the band in a plane generally perpendicular to the axis of the container finish when the cap portion is actuated in the direction to remove it from the container. The first or second projections are discontinuous around the circumference thereby forming a structure of circumferentially spaced bumps.

Claim 1
Independent Claim
205 words
A container for a tamper-evident closure comprising a cap portion of cup-like form, a tamper-evident band connected to the cap portion by fracturable means, said tamper-evident band comprising a retaining means projecting radially inwardly, said container comprising a neck finish portion having a discharge opening and closure engagement means which mates with the container engagement means of the cap portion so that the closure can be applied and removed from the container, a first projection spaced axially below the closure engagement means on the container neck finish, a second projection spaced axially below said first projection closely adjacent thereto defining therebetween, a radially inwardly directed circumferentially extending groove having a smallest diameter less than the largest diameter of said first and second projections and cooperatively associated with the retaining means on the tamper-evident band so that upon initial removal, the retaining means on the tamper-evident band engages in the groove to support at least a portion of the band in a plane generally perpendicular to the axis of the container finish when the cap portion is actuated in the direction to remove it from the container, at least one of said projections being discontinuous around the circumference thereby forming a structure of circumferentially spaced bumps.
Claim 2
Dependent Claim
205 words
A container for a tamper-evident closure comprising a cap portion of cup-like form, a tamper-evident band connected to the cap portion by fracturable means, said tamper-evident band comprising a retaining means projecting radially inwardly, said container comprising a neck finish portion having a discharge opening and closure engagement means which mates with the container engagement means of the cap portion so that the closure can be applied and removed from the container, a first projection spaced axially below the closure engagement means on the container neck finish, a second projection spaced axially below said first projection closely adjacent thereto defining therebetween, a radially inwardly directed circumferentially extending groove having a smallest diameter less than the largest diameter of said first and second projections and cooperatively associated with the retaining means on the tamper-evident band so that upon initial removal, the retaining means on the tamper-evident band engages in the groove to support at least a portion of the band in a plane generally perpendicular to the axis of the container finish when the cap portion is actuated in the direction to remove it from the container, at least one of said projections being discontinuous around the circumference thereby forming a structure of circumferentially spaced bumps.
Claim 3
Dependent Claim
182 words
A container for a tamper-evident closure comprising a cap portion of cup like form, a tamper-evident band connected to the cap portion by fracturable means, said tamper-evident band comprising a retaining means projecting radially inwardly, said container comprising a neck portion having a discharge opening and closure engagement means which mate with the container engagement means of the cap portion so that the closure can be applied and removed from the container, a first radially outwardly directed retainer bead spaced below the closure engagement means on the container neck portion having a largest diameter greater than the smallest diameter of the band retaining means, a second radially outwardly directed band spaced axially below said first bead and having a largest diameter slighter greater than the smallest diameter of the retaining means of the tamper-evident band, said second bead further characterized by having a largest diameter less than the largest diameter of said first bead and a cylindrical connecting surface joining the beads coaxial with the container axis extending upward from and having the same diameter as the apex of said second bead.
Claim 4
Dependent Claim
