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. 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, for coupling of a connecting device to the container for introducing a pressure fluid through said at least one opening into a space between the inner and outer container, wherein the container has been manufactured by blow moulding from at least an inner and an outer plastic preform, to form the bag-in-container type container, such that the outer preform forms at least part of the outer container and the inner preform forms at least part of the bag or inner container, and wherein a closure ring is provided to the inner and outer container, at least closing off the space between said inner and outer container, wherein the inner and outer preform are integrally blow moulded to form the bag-in-container type container; wherein coupling elements are provided at opposite sides of said at least one opening, seen in circumferential direction; wherein the outer container and inner container have first and second neck regions respectively, wherein the ring is connected to the free ends of the first and second neck regions; wherein the at least one opening in the neck region of the container is positioned at a level between the free ends of the first and second neck regions.

2. Container according to claim 1 , wherein the bag is suspended by a neck region of the bag in the neck region of the outer container, wherein the neck regions both have a free end opposite a body portion of the container, wherein a closure ring is mounted to the free ends of the inner and outer container, wherein an edge of the free end of the neck region of the inner container lies at a level 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 is mounted by welding.

3. Container according to claim 1 , wherein the inner container is provided at the neck region with an outward facing flange, which has 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 neck regions of the inner and outer container.

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

5. Container according to claim 1 , wherein the ring has been mounted to the inner and outer containers by spin welding.

6. Container according to claim 1 , wherein the ring is provided with an opening, opening into the bag or inner container, which opening is closed by a valve.

7. Container according to claim 1 , wherein at least one of the inner and outer preform is provided with spacer elements, at least in a transition area between the neck regions and the body portion of the container, preventing close contact between at least part of the inner surface of the outer container and the outer surface of the inner container.

8. Tapping assembly for a beverage, comprising a container according to claim 1 , wherein the assembly further comprises a connecting device, connected or connectable 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.

9. 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, for coupling of a connecting device to the container for introducing a pressure fluid through said at least one opening into a space between the inner and outer container, wherein the container has been manufactured by blow moulding from at least an inner and an outer plastic preform, to form the bag-in-container type container, such that the outer preform forms at least part of the outer container and the inner preform forms at least part of the bag or inner container, and wherein a closure ring is provided to the inner and outer container, at least closing off the space between said inner and outer container, wherein the inner and outer preform are integrally blow moulded to form the bag-in-container type container; wherein the ring is provided with at least one circumferential wall part, wherein teeth are provided on said wall part for engaging a spin welding tool.

10. Set of preforms for forming a 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, for coupling of a connecting device to the container for introducing a pressure fluid through said at least one opening into a space between the inner and outer container, wherein the container has been manufactured by blow moulding from at least an inner and an outer plastic preform, to form the bag-in-container type container, such that the outer preform forms at least part of the outer container and the inner preform forms at least part of the bag or inner container, and wherein a closure ring is provided to the inner and outer container, at least closing off the space between said inner and outer container, wherein the inner and outer preform are integrally blow moulded to form the bag-in-container type container; wherein the inner and outer preform are for integrally blow moulding to form the bag-in-container type container, wherein a closure ring is mounted on the inner and outer preform, at least closing off the space between said inner and outer preform; wherein the outer preform and inner preform have first and second neck regions respectively, wherein the ring is connected to the free ends of the first and second neck regions; wherein the at least one opening in the neck region is positioned at a level between the free ends of the neck regions of the inner and outer preform to which the ring is connected.

11. Set of preforms for forming a 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 adiacent thereto, 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 a space between the inner and outer container, wherein the container has been manufactured by blow moulding from at least an inner and an outer plastic preform, to form the bag-in-container type container, such that the outer preform forms at least part of the outer container and the inner preform forms at least part of the bag or inner container, and wherein a closure ring is provided to the inner and outer container, at least closing off the space between said inner and outer container, wherein the inner and outer preform are integrally blow moulded to form the bag-in-container type con
