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 set of 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 attachment channel and a bottom attachment channel that both at least partially circumferentially extend around the indicator section, the bottom channel being further from the end wall than the top channel, the top channel including at least two hinge bridges that are arcuately wider than the frangible connections and remain unbroken when the frangible connections are broken, and the bottom channel being disposed proximate the at least two hinge bridges.

2. The closure of claim 1 , the bottom channel including at least one of the frangible connections.

3. The closure of claim 1 , wherein the attachment channel comprises a top channel and a bottom channel that both at least partially circumferentially extend around the indicator section, the bottom channel including at least two hinge bridges that are arcuately wider than the frangible connections and remain unbroken when the frangible connections are broken, and the top channel being disposed proximate the at least two hinge bridges and including at least one of the frangible connections.

4. The closure of claim 1 , wherein the attachment channel comprises a first attachment channel and a second attachment channel that both at least partially circumferentially extend around the indicator section, the first channel including at least two hinge bridges that are arcuately wider than the frangible connections and remain unbroken when the frangible connections are broken, the second channel being disposed proximate the at least two hinge bridges, and a first end of the second channel being connected to the first channel by an intermediate channel.

5. The closure of claim 1 , wherein the attachment channel has a helical profile and circumferentially extends around the indicator section.

6. The closure of claim 5 , wherein the attachment channel circumferentially extends more than 360 degrees of arc around the indicator section.

7. 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, 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, and

wherein the attachment channel comprises a top attachment channel and a bottom attachment channel that both at least partially circumferentially extend around the indicator section, the bottom channel being further from the end wall than the top channel, the top channel including at least two hinge bridges that are arcuately wider than the frangible connections and remain unbroken when the frangible connections are broken, and the bottom channel being disposed proximate the at least two hinge bridges.

8. The closure of claim 7 , the bottom attachment channel including at least one of the frangible connections.

9. The closure of claim 7 , wherein the attachment channel comprises a top attachment channel and a bottom attachment channel that both at least partially circumferentially extend around the indicator section, the bottom channel including at least two hinge bridges that are arcuately wider than the frangible connections and remain unbroken when the frangible connections are broken, and the top channel being disposed proximate the at least two hinge bridges and including at least one of the frangible connections.

10. The closure of claim 7 , wherein the attachment channel comprises a first attachment channel and a second attachment channel that both at least partially circumferentially extend around the indicator section, the first channel including at least two hinge bridges that are arcuately wider than the frangible connections and remain unbroken when the frangible connections are broken, the second channel being disposed proximate the at least two hinge bridges, and a first end of the second channel being connected to the first channel by an intermediate channel.

11. The closure of claim 7 , wherein the attachment channel circumferentially extends around the indicator section with a helical profile.

12. The closure of claim 11 , wherein the attachment channel circumferentially extends more than 360 degrees of arc around the indicator section.

13. 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;
an indicator section that connects the attachment band to the sidewall, the indicator section including an attachment channel comprising frangible connections that, when broken, provide a visual indication that the closure has been opened; and
a plurality of raised ribs extending radially outward from the outer surface of the sidewall and extending along the sidewall at least a portion of the distance between the outer peripheral edge and the indicator section;
wherein the indicator section is configured to maintain a connection between the tamper-indicating band and the sidewall when a majority of the frangible connections are broken; and
wherein the attachment channel comprises a top attachment channel and a bottom attachment channel that both at least partially circumferentially extend around the indicator section, the bottom channel being further from the end wall than the top channel, the top channel including at least two hinge bridges that are arcuately wider than the frangible connections and remain unbroken when the frangible connections are broken, and the bottom channel being disposed proximate the at least two hinge bridges.

14. The closure of claim 13 , the bottom attachment channel including at least one of the frangible connections.

15. The closure of claim 13 , wherein the attachment channel comprises a top channel and a bottom channel that both at least partially circumferentially extend around the indicator section, the bottom channel including at least two hinge bridges that are arcuately wider than the frangible connections and remain unbroken when the frangible connections are broken, and the top channel being disposed proximate the at least
