Abstract

Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of the at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through the at least one opening into a space between the inner and outer container.

First claim

The invention claimed is:

1. A container of a bag-in-container form, comprising a neck region, a body portion, an outer container, and an inner container adjacent thereto, wherein the neck region of the outer container is provided with at least one opening extending into a space between the outer container and the inner container, wherein the neck region is provided with coupling elements, for coupling of a connecting device to the container for introducing a pressure fluid through said at least one opening into the space between the inner container and the outer container, wherein the container is manufactured by blow moulding from at least an inner plastic preform and an outer plastic preform, to form the container, such that the outer preform forms at least part of the outer container and the inner preform forms at least part of the inner container, and wherein a closure ring is provided to the inner container and the outer container, at least closing off the space between said inner container and said outer container, wherein the inner preform and the outer preform are integrally blow moulded to form the container.

2. The container according to claim 1 , wherein coupling elements are positioned on circumferentially opposite sides of said at least one opening.

3. The container according to claim 2 , wherein the outer container has a first neck region and the inner container has a second neck region, wherein the first neck region has a first free end and the second neck region has a second free end, and the closure ring is connected to the first free end and the second free end.

4. The container according to claim 1 , wherein the inner container is suspended by a neck region of the inner container in the neck region of the outer container, wherein the first neck and the second neck region both have a free end opposite the body portion of the container, wherein the closure ring is mounted to the free ends of the inner container and the outer container, wherein an edge of the free end of the neck region of the inner container is closer to the body portion of the container than an edge of the free end of the neck region of the outer container, such that the ring extends at least partly into the neck region of the outer container, wherein the closure ring is mounted by welding.

5. The container according to claim 1 , wherein the inner container is provided at the neck region with an outward facing flange, wherein the inner container has a first neck region and the outer container has a second neck region, the inner container having an edge positioned close to or in abutment with an inner surface of the outer container above the at least one opening, substantially closing off the space between the first neck region and the second neck region.

6. The container according to claim 1 , wherein the inner container has a free edge opposite the body portion of the container, wherein the free edge has an annular groove open to the side opposite the body portion, and wherein the closure ring is mounted to the free edge, having a skirt extending into said annular groove.

7. The container according to claim 1 , wherein the closure ring is mounted to the inner container and the outer container by spin welding.

8. The container according to claim 1 , wherein the closure ring has an aperture that allows for fluid communication into the inner container, said aperature is configured to be opened or closed by a valve.

9. The container according to claim 1 , wherein the outer container has a first neck region and the inner container has a second neck region, wherein at least one of the inner container and the outer container has spacer elements at a transition area between either the first neck region or the second neck region and the body portion of the container, wherein the spacer elements prevent close contact between at least part of an inner surface of the outer container and an outer surface of the inner container.

10. A tapping assembly for a beverage, comprising the container according to claim 1 , wherein the assembly further comprises a connecting device that is selectively connected to the neck portion of the container, wherein the connecting device comprises at least one connecting element for connecting to the at least one opening, wherein the connecting element is connected to a source of pressurised gas.

11. The container according to claim 1 , wherein the at least one opening extends substantially radially through the neck region of the outer container.

12. A container of a bag-in-container form, comprising a neck region, a body portion, an outer container, and an inner container adjacent thereto, wherein the neck region of the outer container is provided with at least one opening extending there through, into a space between the outer container and the inner container, wherein the neck region is provided with coupling elements, for coupling of a connecting device to the container for introducing a pressure fluid through said at least one opening into the space between the inner container and the outer container, wherein the container is manufactured by blow moulding from at least an inner plastic preform and an outer plastic preform, to form the container, such that the outer preform forms at least part of the outer container and the inner preform forms at least part of the inner container, and wherein a closure ring is provided to the inner container and the outer container, at least closing off the space between said inner container and said outer container, wherein the inner preform and the outer preform are integrally blow moulded to form the container.

13. The container according to claim 12 , wherein in the neck region the space is provided with spacers between the inner container and the outer container.

14. The container according to claim 13 , wherein the spacers comprise ribs.

15. The container according to claim 14 , wherein the spacers are provided as pairs of substantially parallel ribs.

16. The container according to claim 12 , wherein in the neck region the space is provided with spacers between the inner container and the outer container, wherein the spacers comprise ribs, wherein the spacers are provided as pairs of substantially parallel ribs which extend into a shoulder portion of the container, wherein each pair of ribs forms a channel in between them.
