Abstract

The invention provides a container closure (2) assembly comprising: a container neck (1) having side walls defining an opening at one end thereof and a lip (5) extending around the opening, wherein an inner surface (7) of the side walls proximate to said lip (5) is inwardly tapered; a closure (2) for said neck (1), the closure (2) having a base portion (3) and a skirt portion; a first screw thread on the neck (1); a second screw thread on an inner surface (7) of the skirt of the closure (2); said first and second screw threads being configure to enable a user to secure, remove and resecure the closure (2) into a sealing position on the neck (1) by rotation of the cap on the neck (1); a sealing plug (8) extending from said base portion (3) of the closure (2) inside and substantially concentric with said skirt portion of the closure (2), wherein the sealing plug (8) comprises a plurality of circumferential sealing ribs (9) on an outer surface of said sealing plug (8) for engagement with said inner surface (7) of the container neck (1) when the closure (2) is secured on the container neck (1); at least one flexible sealing fin (10, 11) between the sealing plug (8) and the closure (2) skirt for engagement with the lip (5) of the container when the closure (2) is secured on the container neck (1); and at least one circumferential sealing (14) rib on an inner surface of said closure (2) for engagement with an outer surface of the container neck (1) proximate to said lip (5) when the closure (2) is secured on the container neck (1). The assembly is especially suitable for forming gas-tight seals on carbonated beverage containers.

Claims (23)

1. A container closure assembly comprising:
a container neck having side walls defining an opening at one end thereof and a lip extending around the opening, wherein an inner surface of the side walls proximate to said lip is inwardly tapered;

a closure for said neck, the closure having a base portion and a skirt portion;

a first screw thread on the neck;

a second screw thread on an inner surface of the skirt of the closure;

said first and second screw threads being configured to enable a user to secure, remove and resecure the closure into a sealing position on the neck by rotation of the cap on the neck;

a sealing plug extending from said base portion of the closure inside and substantially concentric with said skirt portion of the closure, wherein the sealing plug comprises a plurality of circumferential sealing ribs on an outer surface of said sealing plug for engagement with said inner surface of the container neck when the closure is secured on the container neck;

at least one flexible sealing fin between the sealing plug and the closure skirt for engagement with the lip of the container when the closure is secured on the container neck; and at least one circumferential sealing rib on an inner surface of said closure for engagement with an outer surface of the container neck proximate to said lip when the closure is secured on the container neck.
2. A container closure assembly according to any preceding claim, wherein at least one of the sealing ribs on the plug or the inner surface of the closure has a substantially triangular cross-section.
3. A container closure assembly according to any preceding claim, wherein in use a first one of said sealing ribs on the plug is located substantially the same distance from the bottom of the closure as a first one of the sealing ribs on the inner surface of the closure, whereby the lip of the container neck is pinched between the said first sealing ribs when the closure is in the secured position on the container neck.
4. A container closure assembly according to any preceding claim, wherein the sealing ribs on the plug or the inner surface of the closure have a height in the range of 10 to 250 micrometers.
5. A container closure assembly according to any preceding claim, wherein the plurality of sealing ribs on the sealing plug have more than one height.
6. A container closure assembly according to claim 6, wherein the sealing rib furthest from the base of the closure has a greater height than the sealing rib closest to the base of the closure.
7. A container closure assembly according to any preceding claim, wherein the outer surface of the sealing plug is tapered inwardly from the base of the closure.
8. A container closure assembly according to any preceding claim, wherein at least one said sealing fin extends downwardly and outwardly from the base of the closure between the sealing plug and the closure skirt.
9. A container closure assembly according to claim 9, further comprising a second sealing fin extending downwardly and inwardly from the base of the closure between the sealing plug and the closure skirt.
10. A container closure assembly according to any preceding claim, wherein at least one said sealing fin has a height of from 1 to 4 mm.
11. A container closure assembly according to any preceding claim, wherein at least one stop surface is provided proximate to the base of the closure, whereby at least one sealing fin abuts against the stop surface when the closure is secured on the container neck.
12. A container closure assembly according to any preceding claim, wherein the container lip is fully radiused.
13. A container closure assembly according to any preceding claim, wherein the closure can be secured and resecured on the container neck by a single smooth rotation through 360° or less, preferably through 180° or less, and more preferably through about 90°.
14. A container closure assembly according to any preceding claim, wherein the first and second threads are multiple start threads.
15. A container closure assembly according to any preceding claim, wherein the first and second threads are substantially continuous helical threads.
16. A container closure assembly according to any preceding claim, wherein the container and closure further comprise complementary locking elements on the container neck and the closure that block or resist unscrewing of the closure from the fully secured position on the container neck until a predetermined minimum opening torque is applied.
17. A container closure assembly according to claim 16, wherein the locking elements comprise a longitudinal locking rib on one of the container neck or the skirt portion of the closure, and a complementary locking ramp on the other of the container neck and the skirt portion of the closure, said locking rib abutting against the retaining edge of the locking ramp when the closure is fully secured on the container neck.
18. A container closure assembly according to any preceding claim, further comprising a projecting stop surface on one of the container neck and the closure skirt for abutment against a second stop or a thread on the other of the container neck or the closure to block over-tightening of the closure beyond a predetermined angular sealing position of the closure on the container neck.
19. A container closure assembly according to any preceding claim, wherein the torque required to secure the closure in a sealing position on the container neck is from about 0.7 Nm to about 0.9 Nm.
20. A container closure assembly according to any preceding claim, wherein the assembly achieves a sealing pressure around at least one circumferential surface between the container neck and the closure at the fully closed position of at least about 7 MPa (1000 psi).
21. A container closure assembly according to claim 20, wherein the assembly provides at least two such circumferential seals between the container neck and the closure at the fully closed position.
22. A beverage container comprising a container closure assembly according to any preceding claim.
23. A beverage container according to claim 22 which is a carbonated beverage container.
