Abstract

A package includes a container with a crown closure bead and an external thread segment having a diameter greater than that of the crown closure bead, a crown closure coupled to the crown closure bead, and a multi-piece closure assembly coupled to the crown closure and the container. The closure assembly includes an inner shell, a seal liner carried by the inner shell and positioned against the crown closure, and an outer shell. The inner shell has an inner skirt having at least one internal thread segment to cooperate with the external thread segment of the container. The outer shell has an outer skirt with an internal retention bead for cooperating with an external retention bead of the inner shell to retain the shells together in an axial direction, and outer child-resistant engagement features to cooperate with inner child-resistant engagement features of the inner shell.

First claim

The invention claimed is:

1. A package, comprising:
a container including a neck terminating in a neck finish having a crown closure bead with a first outer diameter, and at least one external thread segment spaced axially away from the crown closure bead and having a second diameter greater than the first outer diameter of the crown closure bead;
a crown closure coupled to the crown closure bead of the container neck finish and including:
a shell, and
a seal liner carried by the shell, to provide a seal between the shell and the container; and

a multi-piece closure assembly coupled to the crown closure and the container neck finish, and including:
an inner shell including:
an inner base wall having an axially inboard surface,
an inner skirt depending from the base wall and having at least one internal thread segment to cooperate with the at least one external thread segment of the container neck finish and also having at least one external retention bead, and
inner child-resistant engagement features carried by at least one of the inner base wall or the inner skirt; and

an outer shell including:
an outer base wall,
an outer skirt depending from the outer base wall and having an internal retention bead for cooperating with the external retention bead of the inner shell to retain the shells together in an axial direction, and
outer child-resistant engagement features carried by at least one of the outer base wall or the outer skirt to cooperate with the inner child-resistant engagement features of the inner shell.

2. The package set forth in claim 1 , wherein the inner child-resistant engagement features include a circumferential array of lugs projecting axially outwardly from the inner base wall, and wherein the outer child-resistant engagement features include a corresponding circumferential array of lugs projecting axially inwardly from the outer base wall.

3. The package set forth in claim 1 , wherein the inner child-resistant engagement features include a circumferential array of wings projecting axially outwardly from the inner base wall, and wherein the outer child-resistant engagement features include a corresponding circumferential array of wings projecting axially inwardly from the outer base wall.

4. The package set forth in claim 1 , wherein the multi-piece closure assembly also includes at least one spring carried between the inner and outer shells to bias the shells axially apart.

5. The package set forth in claim 1 , further comprising a tamper-evident shrink wrap or sleeve applied over the closure assembly and to the container.

6. The package set forth in claim 1 , wherein the outer base wall includes a recessed wall portion establishing an axially outwardly facing pocket having at least one bottle opener feature.

7. The package set forth in claim 1 , wherein the inner skirt of the inner shell includes an inwardly facing surface in contact with a skirt of the crown closure, and configured to crimp the skirt of the crown closure to the crown bead of the container neck finish when the multi-piece closure is threaded to the container neck finish.

8. The package set forth in claim 1 , wherein the inner shell is configured to carry the crown closure before being applied to the container.

9. The package set forth in claim 1 , wherein a lower end of the inner skirt of the inner shell has a frangible tamper-evident band for cooperating with a tamper-evident bead on the container neck finish below the at least one external thread segment.

10. The package set forth in claim 1 , wherein the container is composed of glass, the closure shells are composed of plastic, and the crown closure shell is composed of metal.

11. A package, comprising:
a container including a neck and a neck finish having a crown closure bead with a first outer diameter, and at least one external thread segment spaced axially away from the crown closure bead and having a second diameter greater than the first outer diameter of the crown closure bead;
a crown closure coupled to the crown closure bead of the container neck finish; and
a multi-piece closure assembly coupled to the crown closure and the container neck finish, and including:
an inner shell including:
an inner base wall having an axially inboard surface,
an inner skirt depending from the base wall and having at least one internal thread segment to cooperate with the at least one external thread segment of the container neck finish and also having at least one external retention bead, and
a circumferential array of child-resistant engagement features projecting axially outwardly from the inner base wall;

a seal liner carried by the axially inboard surface of the inner base wall, and positioned against the crown closure; and
an outer shell including:
an outer base wall,
an outer skirt depending from the outer base wall and having an internal retention bead for cooperating with the external retention bead of the inner shell to retain the shells together in an axial direction, and
a circumferential array of child-resistant engagement features projecting axially inwardly from the outer base wall.

12. The package set forth in claim 11 , wherein the multi-piece closure assembly also includes at least one spring carried between the inner and outer shells to bias the shells axially apart.

13. The package set forth in claim 11 , further comprising a tamper-evident shrink wrap or sleeve applied over the closure assembly and to the container.

14. The package set forth in claim 11 , wherein the container is composed of glass, the closure shells are composed of plastic, and the crown closure shell is composed of metal.

15. A package, comprising:
a container including a neck and a neck finish having a crown closure bead with a first outer diameter, at least one external thread segment spaced axially away from the crown closure bead and having a second diameter greater than the first outer diameter of the crown closure bead, and a tamper-evident bead spaced axially away from the at least one thread segment;
a crown closure coupled to the crown closure bead of the container neck finish; and
a multi-piece closure assembly coupled to the crown closure and the container neck finish, and including:
an inner shell including:
an inner base wall having an axially inboard surface,
an inner skirt depending from the base wall and having at least one internal thread segment to cooperate with the at least one external thread segment of the container neck finish and also having at least one external retention bead,
a circumferential array of child-resistant engagement features projecting radially outwardly from the inner base wall and the inner skirt, and
a frangible tamper-evident band at a lower end of the inner skirt for cooperating with the tamper-evident bead on the container neck finish; and

an outer shell including:
an outer base wall,
an outer skirt depending from the outer base wall and having an internal retention bead for cooperating with the external retention bead of the inner shell to retain the shells together in an axial direction, and
a circumferential array of child-resistant engagement features projecting axially and radially inwardly from the outer base wall and the outer skirt.

16. The package set forth in claim 15 , wherein the outer base wall includes a recessed wall portion establishing an axially outwardly facing pocket having at least one bottle opener feature.

17. The package set forth in claim 15 , wherein the inner skirt of the inner shell includes an inwardly facing surface in contact
