Abstract

A closure assembly for piercing and creating access to a container whose mouth is normally sealed by a thin membrane applied to a rim of the container.

Claims (42)

1. A closure for a membrane sealed container, said closure comprising:

an annular side wall;

a top wall connected to said annular side wall, the top wall having a center outer surface;

an annular ring extending upward from the top wall,

a recessed surface disposed between the annular ring and the center outer surface, the recessed surface configured to form a channel for receiving the top rim of the membrane sealed container when the closure device is inverted and pushed against the top of the membrane sealed container;

at least one piercing member disposed on the center outer surface in spaced apart relation to the annular ring, the at least one piercing member having a first height above the center outer surface;

at least one directional plow disposed on the center outer surface separate from and in spaced apart relation to the at least one piercing member, the at least one directional plow having a second height above the center outer surface that is less than the first height of the at least one piercing member.

2. The closure device of claim 1 , wherein the at least one piercing member further comprises two or more piercing members arranged along an arc.

3. The closure device of claim 1 , wherein the at least one directional plow comprises a pair of directional plows disposed on opposite sides of the at least one piercing member.

4. The closure device of claim 3 , wherein the directional plows further comprise arrow-shaped members having a head portion and a body portion.

5. The closure device of claim 4 , further comprising a first directional plow having an arcuate body, the first directional plow being oriented in the clockwise direction.

6. The closure device of claim 5 , further comprising a second directional plow having an arcuate body, the second directional plow being oriented in the counterclockwise direction.

7. The closure device of claim 1 , wherein the recessed surface has a plurality of openings defined therein.

8. The closure device of claim 1 , wherein an outer surface of the annular side wall has a plurality of ridges disposed thereon.

9. The closure device of claim 1 , wherein an inner surface of the annular side wall has threads disposed thereon.

10. The closure device of claim 1 , wherein the recessed surface allows the piercing member to penetrate farther into the membrane seal.

11. A container comprising:

a container body defining a pour orifice, said pour orifice fluidly sealed by a pierceable membrane; and

a cap member constructed for attachment to said container body adjacent said pour orifice, said cap member comprising:

an annular side wall;

a top wall connected to said annular side wall,

an annular ring extending upward from the top wall,

a recessed surface extending between the annular ring and a center outer surface to form a channel for receiving the top of the membrane sealed container when the closure device is inverted;

at least one piercing member disposed on the center outer surface in spaced apart relation to the annular ring, the at least one piercing member having a first height above the center outer surface, the at least on piercing member configured to pierce the pierceable membrane when the cap is inverted and rotated on top of the container body adjacent the pour opening;

at least one directional plow disposed on the center outer surface separate from and in spaced apart relation to the at least one piercing member, the at least one directional plow having a second height above the center outer surface that is less than the first height of the at least one piercing member, the at least one directional plow configured to maintain tension on the pierceable membrane.

12. The closure device of claim 11 , wherein the at least one piercing member further comprises two or more piercing members arranged along an arc.

13. The closure device of claim 11 , wherein the at least one directional plow comprises a pair of directional plows disposed on opposite sides of the at least one piercing member.

14. The closure device of claim 13 , wherein the directional plows further comprise arrow-shaped members having a head portion and a body portion.

15. The closure device of claim 14 , further comprising a first directional plow having an arcuate body, the first directional plow being oriented in the clockwise direction.

16. The closure device of claim 15 , further comprising a second directional plow having an arcuate body, the second directional plow being oriented in the counterclockwise direction.

17. The closure device of claim 11 , wherein the recessed surface has a plurality of openings defined therein.

18. The closure device of claim 11 , wherein an outer surface of the annular side wall has a plurality of ridges disposed thereon.

19. The closure device of claim 11 , wherein an inner surface of the annular side wall has threads disposed thereon.

20. A closure assembly for use with a membrane sealed container, said closure assembly comprising:

a closure shell having an annular side wall;

a top wall connected to said annular side wall, the top wall having a center outer surface;

an annular ring extending upward from the top wall,

a recessed surface disposed between the annular ring and the center outer surface, the recessed surface configured to form a channel for receiving the top rim of the membrane sealed container when the closure device is inverted and pushed against the top of the membrane sealed container;

at least one piercing member disposed on the center outer surface in spaced apart relation to the annular ring, the at least one piercing member having a first height above the center outer surface;

at least one directional plow disposed on the center outer surface separate from and in spaced apart relation to the at least one piercing member, the at least one directional plow having a second height above the center outer surface that is less than the first height of the at least one piercing member;

a closure core removably attached in the interior of the closure shell, the closure core configured to engage with the top of the membrane sealed container.

21. The closure assembly of claim 20 , wherein the inner surface of the closure core has thread disposed thereon for engaging with corresponding threads on the top of the membrane sealed container.
