Abstract

A closure for a container includes a tamper band that remains attached to the closure after the container is opened and the closure is removed. The tamper band includes a shaped internal surface and gaps to interact with a dispenser assembly for the container. The dispenser assembly includes tabs to interact with the tamper band of the closure and an alignment rim to engage with the internal surface of the tamper band.

First claim

What is claimed is:

1. A plastic closure for a container comprising:
a sidewall defining a longitudinal axis having a first end and a second end;
an end wall sealed to the first end of the sidewall;
a thread extending from an inner surface of the sidewall; and
a tamper-indicating band positioned below the second end of the sidewall, the tamper indicating band comprising:
a first portion including a clockwise facing surface and a counterclockwise facing surface, wherein the first portion extends at least 130 degrees around the second end of the sidewall;
a first hinge connection coupling the first portion to the second end of the sidewall, wherein the first hinge connection is located equidistant from the clockwise facing surface and from the counterclockwise facing surface of the first portion of the tamper-indicating band;
a second portion including a clockwise facing surface and a counterclockwise facing surface, wherein the second portion extends at least 130 degrees around the second end of the sidewall;
a second hinge connection coupling the second portion to the second end of the sidewall, wherein the first hinge connection and the second hinge connection are located opposite each other around the circumference of the tamper-indicating band;
a first gap defined between the clockwise facing surface of the first portion and the counterclockwise facing surface of the second portion; and
a second gap defined between the clockwise facing surface of the second portion and the counterclockwise facing surface of the first portion;
a first frangible connection connecting the clockwise facing surface of the first portion to the counterclockwise facing surface of the second portion; and
a second frangible connection connecting the clockwise facing surface of the second portion to the counterclockwise facing surface of the first portion.

2. A plastic closure for a container comprising:
a sidewall defining a longitudinal axis having a first end and a second end;
an end wall sealed to the first end of the sidewall;
a thread extending from an inner surface of the sidewall; and
a tamper-indicating band positioned below the second end of the sidewall, the tamper indicating band comprising:
a first portion including a clockwise facing surface and a counterclockwise facing surface, wherein the first portion extends at least 130 degrees around the second end of the sidewall;
a first hinge connection coupling the first portion to the second end of the sidewall;
a second portion including a clockwise facing surface and a counterclockwise facing surface, wherein the second portion extends at least 130 degrees around the second end of the sidewall;
a second hinge connection coupling the second portion to the second end of the sidewall;
a first gap defined between the clockwise facing surface of the first portion and the counterclockwise facing surface of the second portion; and
a second gap defined between the clockwise facing surface of the second portion and the counterclockwise facing surface of the first portion;
a first frangible connection connecting the clockwise facing surface of the first portion to the counterclockwise facing surface of the second portion; and

a second frangible connection connecting the clockwise facing surface of the second portion to the counterclockwise facing surface of the first portion; and
the first hinge connection having a first connection width, the second hinge connection having a second connection width, the first frangible connection having a third connection width and the second frangible connection having a fourth connection width, wherein the first, second, third, and fourth connection widths are all equal.

3. The plastic closure of claim 2 wherein the radial dimensions of the clockwise facing surfaces of the first and second portions of the tamper-indicating band are greater than a radial dimension of the first and second frangible connections.

4. The plastic closure of claim 2 wherein the first portion extends at least 150 degrees around the second end of the sidewall, wherein the second portion extends at least 150 degrees around the second end of the sidewall.

5. A cap and dispenser assembly for a container comprising:
a dispenser comprising:
a tube defining a longitudinal axis having an exterior surface and a top sealing surface defining a first end of the tube, the tube having a central channel extending between a first opening and a second opening;
a thread extending radially outward from the exterior surface of the tube;
an annular rim extending radially outward from the exterior surface of the tube below the thread;
a first tab extending radially outward from the exterior surface of the tube located above the annular rim and below the thread; and
a second tab extending radially outward from the exterior surface of the tube located above the annular rim and below the thread; and

a cap comprising:
a sidewall having an internal surface and a first end and a second end, centered around the longitudinal axis;
an outer shell surrounding the sidewall;
a support structure coupling the outer shell to the sidewall such that rotation of the outer shell imparts rotation to the sidewall;
a thread on the internal surface of the sidewall configured to engage with the thread on the exterior surface of the tube; and
a tamper band extending from the second end of the sidewall, the tamper band comprising:
a first gap defined in the tamper band;
a first frangible connection between the tamper band and the second end of the sidewall, the first frangible connection located above the first gap;
a second gap defined in the tamper band;
a second frangible connection between the tamper band and the second end of the sidewall, the second frangible connection located above the second gap;

wherein the tamper band extends around the dispenser such that the first tab of the dispenser extends at least a portion of the distance through the first gap and the second tab of the dispenser extends at least a portion of the distance through the second gap;
wherein upon rotation of the cap relative to the dispenser, tamper-band surfaces defining the first gap and the second gap engage the first tab and second tab, respectively, causing the first and second frangible connections to break.

6. The cap and dispenser assembly of claim 5 wherein the outer shell of the cap further includes an upper opening that has a first radius and the tamper band has a second radius, and the second radius is smaller than the first radius.

7. The cap and dispenser assembly of claim 5 wherein the tamper band has a longitudinal height and a radial width and the longitudinal height of the tamper band is greater than the radial width of the tamper band.

8. The cap and dispenser assembly of claim 5 wherein the dispenser further comprises a pouch support structure having an outer surface and further comprising a pouch coupled to the pouch support structure such that the first opening of the tube of the dispenser is located outside of the pouch and that the second opening of the tube of the dispenser is located within a contents cavity of the pouch.

9. The cap and dispenser assembly of claim 5 wherein the tamper band includes a first hinged connection and a second hinged connection both coupling the tamper band to the second end of the sidewall of the cap, wherein the first hinged connection is located equidistance from both the first gap and the second gap around a circumference of the tamper band, wherein the second hinged connection is located equidistance from both the first gap and the second gap around a circumference of the tamper band, wherein the first hinged connection and the second hinged connec
