Abstract A tamper indicating package comprising a container having a neck with a threaded finish, an annular bead on the neck, a plastic closure which includes a base wall and a depending peripheral skirt having threads interengaging the threads of the container, and a tamper indicating band attached to the skirt by a plurality of weakened portions defining a line of severing. An annular flange extends axially upwardly and inwardly from the tamper indicating band toward the base wall of the closure and comprises a first continuous annular flange portion connected to the band by a hinge portion and a second portion which has free ends of the segment portions engaging beneath the bead on the container when the closure is threaded onto the container. The second portion comprises a plurality of segment portions extending upwardly and inwardly from the first continuous portion. The flange is bent intermediate its ends so that the second portion extends inwardly at a greater angle than the first continuous flange portion. The tamper indicating band has a plurality of circumferentially spaced recesses on an inner surface into which the segments extend when the closure is being applied to a container.
A tamper indicating closure comprising a plastic closure which includes a base wall and a depending peripheral skirt having threads adapted to interengage threads of a container, and a tamper indicating band attached to said skirt by one or more weakened portions defining a line of severing, an annular flange extending axially upwardly and inwardly from said tamper indicating band toward said base wall of the closure, and said flange comprising a first continuous annular flange portion connected to the inner surface of said tamper indicating band by a hinge spaced radially inwardly from said inner surface of said band, said flange being bent intermediate its ends such that a second portion extends inwardly at a greater angle to the axis of said closure than said first portion being adapted to engage beneath a bead on a container, said second portion comprising a plurality of circumferentially spaced segments separated by narrow slots extending upwardly and inwardly from the continuous flange, said band having a plurality of circumferentially spaced recesses constructed and arranged such that when the closure is being applied to a container, a part of each segment extends into the adjacent recess.

A tamper indicating closure comprising a plastic closure which includes a base wall and a depending peripheral skirt having threads adapted to interengage threads of a container, and a tamper indicating band attached to said skirt by one or more weakened portions defining a line of severing, an annular flange extending axially upwardly and inwardly from said tamper indicating band toward said base wall of the closure, and said flange comprising a first continuous annular flange portion connected to the inner surface of said tamper indicating band by a hinge spaced radially inwardly from said inner surface of said band, said flange being bent intermediate its ends such that a second portion extends inwardly at a greater angle to the axis of said closure than said first portion being adapted to engage beneath a bead on a container, said second portion comprising a plurality of circumferentially spaced segments separated by narrow slots extending upwardly and inwardly from the continuous flange, said band having a plurality of circumferentially spaced recesses constructed and arranged such that when the closure is being applied to a container, a part of each segment extends into the adjacent recess.
Claim 3
Dependent Claim
18 words
The tamper indicating closure set forth in claim 1 wherein said recesses and segments are complementary in shape.
Claim 4
Dependent Claim
25 words
The tamper indicating closure set forth in claim 2 wherein the recesses have a circumferential width substantially equal to the circumferential width of said segments.
Claim 5
Dependent Claim
27 words
The tamper indicating closure set forth in claim 3 wherein the axial height of each said recess is greater than the axial height of each said segment.
Claim 6
Dependent Claim
72 words
The tamper indicating closure set forth in any one of claims 1-4 including a plurality of circumferentially spaced projections on the inner surface of said band between said segments such that when the segments engage an annular bead on a container when the closure is being removed from a container, the projections extend into the slots between said segments to assist in maintaining concentricity of the tamper indication closure on the container.
