Abstract

A closure that remains coupled to a container after the upper portion of the closure has been rotatably removed from the container. The closure may include an attachment channel, which includes alternating segments of linear openings and frangible connections. The attachment channel may also include two hinge bridges that remain unbroken when one or more of the frangible connections are broken.

First claim

I claim:

1 . A closure comprising:
an end wall including an outer peripheral edge; a sidewall extending downward and away from the outer peripheral edge of the end wall, the sidewall containing an inner surface; a container engagement structure extending radially inward from the inner surface of the sidewall; an indicator section including an attachment channel that comprises frangible connections and linear openings between the frangible connections, the frangible connections providing a visual indication, when broken, that the closure has been opened; and an attachment band that remains coupled to a container inlet after the frangible connections are broken, the indicator section maintaining a connection between the sidewall and the attachment band when the frangible connections are broken; wherein the attachment channel comprises a top channel and a bottom channel, wherein both the top channel and the bottom channel at least partially circumferentially extend around the indicator section, the bottom channel being further from the end wall than the top channel, the bottom channel including at least two hinge bridges that are circumferentially wider than the frangible connections and remain unbroken when the frangible connections are broken, wherein the top channel is between the end wall and at least one of the at least two hinge bridges.

2 . The closure of claim 1 , the top channel being disposed proximate the at least two hinge bridges and including at least one of the frangible connections.

3 . The closure of claim 1 , the top channel including at least one of the frangible connections.

4 . A closure comprising:
an end wall including an outer peripheral edge; a sidewall extending downward and away from the outer peripheral edge of the end wall, the sidewall containing an inner surface; a container engagement structure extending radially inward from the inner surface of the sidewall; an indicator section including an attachment channel that comprises frangible connections and linear openings between the frangible connections, the frangible connections providing a visual indication, when broken, that the closure has been opened; and an attachment band that remains coupled to a container inlet after the frangible connections are broken, the indicator section maintaining a connection between the sidewall and the attachment band when the frangible connections are broken; wherein the attachment channel comprises a top channel and a bottom channel, the top channel including at least one of the frangible connections, wherein both the top channel and the bottom channel at least partially circumferentially extend around the indicator section, the bottom channel being further from the end wall than the top channel, the bottom channel including at least two hinge bridges that are circumferentially wider than the frangible connections and remain unbroken when the frangible connections are broken, the bottom channel including at least one of the frangible connections, the top channel including at least one of the frangible connections.

5 . The closure of claim 1 , wherein the end wall and the sidewall are centered on an axis, and wherein the frangible connections are disposed approximately every 20 degrees of arc apart from each other with respect to the axis.

6 . A closure comprising:
an end wall including an outer peripheral edge; a sidewall extending downward and away from the outer peripheral edge of the end wall, the sidewall containing an inner surface; a container engagement structure extending radially inward from the inner surface of the sidewall; an indicator section including an attachment channel that comprises frangible connections and linear openings between the frangible connections, the frangible connections providing a visual indication, when broken, that the closure has been opened; and an attachment band that remains coupled to a container inlet after the frangible connections are broken, the indicator section maintaining a connection between the sidewall and the attachment band when the frangible connections are broken; wherein the attachment channel comprises a top channel and a bottom channel, wherein both the top channel and the bottom channel at least partially circumferentially extend around the indicator section, the bottom channel being further from the end wall than the top channel, the bottom channel including at least two hinge bridges that are circumferentially wider than the frangible connections and remain unbroken when the frangible connections are broken, the bottom channel including at least one of the frangible connections.

7 . The closure of claim 1 , wherein the top channel and the bottom channel are substantially parallel to each other.

8 . The closure of claim 1 , wherein the top channel is between the end wall and at least two of the at least two hinge bridges.

9 . A closure comprising:
an end wall including an outer peripheral edge; a sidewall extending downward and away from the outer peripheral edge of the end wall, the sidewall containing an inner surface; a container engagement structure extending radially inward from the inner surface of the sidewall; an attachment band configured to be coupled to a container inlet; and an indicator section that connects the attachment band to the sidewall, the indicator section including an attachment channel with frangible connections, wherein the attachment channel comprises a top channel and a bottom channel, wherein both the top channel and the bottom channel at least partially circumferentially extend around the indicator section, the bottom channel being further from the end wall than the top channel, the bottom channel including at least two hinge bridges that are circumferentially wider than the frangible connections and remain unbroken when the frangible connections are broken, wherein the top channel is between the end wall and at least one of the at least two hinge bridges, the indicator section having two configurations:
an open configuration that provides a visual indication that the closure has been opened as a result of at least a majority of the frangible connections being broken; and
a closed configuration that provides an indication that the closure has not been opened.

10 . The closure of claim 9 , the top channel being disposed proximate the at least two hinge bridges and including at least one of the frangible connections.

11 . A closure comprising:
an end wall including an outer peripheral edge; a sidewall extending downward and away from the outer peripheral edge of the end wall, the sidewall containing an inner surface; a container engagement structure extending radially inward from the inner surface of the sidewall; an attachment band configured to be coupled to a container inlet; and an indicator section that connects the attachment band to the sidewall, the indicator section including an attachment channel with frangible connections, wherein the attachment channel comprises a top channel and a bottom channel, wherein both the top channel and the bottom channel at least partially circumferentially extend around the indicator section, the bottom channel being further from the end wall than the top channel, the bottom channel including at least two hinge bridges that are circumferentially wider than the frangible connections and remain unbroken when the frangible connections are broken, the indicator section having two configurations:
an open configuration that provides a visual indication that the closure has been opened as a result of at least a majority of the frangible connections being broken; and
a closed configuration that provides an indic
