Abstract

Tapping assembly for a beverage, including container including a first and second container, wherein the first container has a neck portion and the second container is suspended in the first container, from the neck portion thereof. A neck region of the container is provided with at least one opening in a side wall thereof, preferably in a neck region of the first container, opening into a space between the first and second containers. The assembly further includes a connecting device, connected or connectable to the neck portion, wherein the connecting device includes 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.

First claim

The invention claimed is:

1. A tapping assembly for a beverage, comprising a bag-in-container type container comprising a first container and a second container, wherein the first container has a neck portion and the second container has a neck portion extending at least partly inside the neck portion of the first container, wherein a neck region of the bag-in-container type container is provided with at least one opening through a wall of the neck portion of the first container or through a wall of the neck portion of the second container opening into a space between the first and second containers, wherein the assembly further comprises a connecting device, connected or connectable to the neck region of the bag-in-container type container, wherein the connecting device comprises at least one gas connecting element for connecting to the at least one opening, wherein the gas connecting element is connected to a source of pressurized gas and is movable from a side wall of a coupling opening in a substantially radial direction that is perpendicular to a longitudinal axis of the neck region of the bag-in-container type container.

2. The tapping assembly according to claim 1 , wherein the first and second container have a body portion, wherein the first and second container are gas tightly connected to each other at the neck portions thereof, at a side of the at least one opening opposite the body portions.

3. The tapping assembly according to claim 1 , wherein a body forming portion of the first container is more rigid than a body forming portion of the second container, wherein the at least one opening opens into said space in substantially the radial direction, perpendicular to the longitudinal axis of the neck region, and wherein the gas connecting element connects to said at least one opening in the substantially radial direction.

4. The tapping assembly according to claim 1 , wherein the neck portion of the first container is provided with at least one first coupling element and the connecting device is provided with at least one complementary second coupling element, wherein the gas connecting device is or can be coupled to the neck region, wherein said at least one gas connecting element is or becomes connected to the at least one opening.

5. The tapping assembly according to claim 1 , wherein the connecting device comprises a first and second part, moveable relative to each other, wherein in a first relative position of the parts the gas connecting element is in a retracted position and in a second relative position of the parts the gas connecting element is in an extended position, wherein the connecting device comprises a mechanism configured wherein movement of the gas connecting element between the retracted and the extended positions and vice versa is enforced by the relative movement of the parts through said mechanism, wherein the first and second part are rotatable relative to each other around the longitudinal axis of the neck region of the bag-in-container type container,
wherein the said relative rotation of the parts enforces said movement of the gas connecting element.

6. The tapping assembly according to claim 5 , wherein the mechanism is an at least partly rotating mechanism.

7. The tapping assembly according to claim 1 , wherein the connecting device comprises an overpressure release connector, in a connecting line for the source of pressurised gas or for connecting to the first opening or to a second opening provided in said neck region of the bag-in-container type container.

8. The tapping assembly according to claim 7 , wherein the first and second opening are positioned radially opposite each other.

9. The tapping assembly according to claim 1 , wherein the first and second containers are closed off at the neck portions to each other and/or by a closure,
wherein the connecting device comprises a connector in an opening positioned over the valve when the connecting device has been connected to the neck region,
wherein when the connector is placed in said opening with the connecting device connected to the bag-in-container type container, the connector opens a valve of the container.

10. The tapping assembly according to claim 9 , wherein the connector is provided with an opening in and/or through which a dispense line extends, which at one end is connected to a dispense adaptor for connecting to and opening the valve, wherein the dispense line and the dispense adapter are disposable.

11. The tapping assembly according to claim 1 , wherein the connecting element is movable relative to the at least one opening at least partially in a direction substantially perpendicular to the longitudinal axis of the neck region of the bag-in-container type container.

12. The tapping assembly according to claim 11 , wherein the respective neck portions of the first and second containers have an axial direction and the at least one opening extends, with respect to the axial direction, in a substantially radial direction of the relevant neck portion of the first or second container and wherein the connecting element is movable in said substantially radial direction, between a release position spaced apart from the at least one opening and a connecting position gastight connecting to said at least one opening.

13. The tapping assembly according to claim 1 , wherein said at least one opening is provided in the neck portion of the first container.

14. The tapping assembly according to claim 1 , wherein the first and second containers have been integrally blow moulded into the bag-in-container type container.

15. A connecting device for connecting a dispense line and a gas line to a bag-in-container type container, comprising a first part and a second part, movably connected to said first part, wherein at least one of the first and/or second part is provided with a coupling opening extending in a substantially axial direction, with coupling elements for physically connecting the device to a part of a bag-in-container extending inside said coupling opening, wherein the connecting device is further provided with at least one gas connecting element, the connecting device further comprising a mechanism for moving the at least one gas connecting element between a position connecting the gas line to the bag-in-container and a position disconnecting the gas line from the bag-in-container, wherein the gas connecting element is movable from a side wall of the coupling opening, in a substantially radial direction of the coupling opening.

16. The connecting device according to claim 15 , wherein a connector is releasably provided at one end of the coupling opening, wherein:
the connector comprises a coupler for opening a valve of the bag-in-container type container to which the connecting device is connected and a tapping line extending from said connector; or
the connector comprises an opening in and/or through which a dispense line extends, which at one end is connected to a dispense adaptor for connecting to and opening the valve of a container to which the connecting device is connected;

wherein the dispense line and the dispense adapter are disposable.

17. The connecting device according to claim 15 , wherein a gas inlet line is coupled to the at least one connecting element, for introducing gas under pressure into the space between inner and outer containers of a bag-in-container to which the connecting device is connected.

18. The connecting device according to claim 15 , wherein the connecting device further comprises an overpressure release device, for coupling to a
