Abstract

Tapping assembly for beverages, comprising a pressure chamber and a pressurising device, wherein the pressure chamber comprises a lid closing off the pressure chamber at least partly, with an opening in said lid, and a container extending with a neck through said opening and a body extending inside said pressure chamber, wherein a first flange extending around the neck lies at a side of the lid facing the pressure chamber and at least one element extending from said neck lies at the opposite side of the lid, the device being provided with at least one closure element engaging said at least one element, forcing said element away from the lid and thereby pulling the first flange towards the lid for sealing the opening by at least the first flange.

Claims

1. Tapping assembly for beverages, comprising a pressure chamber and a pressurising device, wherein the pressure chamber comprises a lid closing off the pressure chamber at least partly, with an opening in said lid, and a container extending with a neck through said opening and a body extending inside said pressure chamber, wherein a first flange extending around the neck lies at a side of the lid facing the pressure chamber and at least one element extending from said neck lies at the opposite side of the lid, the device being provided with at least one closure element engaging said at least one element, forcing said element away from the lid and thereby pulling the first flange towards the lid for sealing the opening by at least the first flange.

2. Tapping assembly according to claim 1, wherein the body of the container is compressible by pressure provided in the pressure chamber by the pressure device.

3. Tapping assembly according to claim 1, wherein the first flange extends further from a longitudinal axis of the neck of the container, measure perpendicular to the longitudinal axis, than the or each said element, preferably such that the neck and the or each said element extending from said neck can pass through said opening but said first flange cannot.

4. Tapping assembly according to claim 1, wherein the at least one element extending from the neck is a second flange, wherein the first and second flange are preferably substantially circular and concentric, wherein the first flange is larger than the opening in the lid, such that it cannot pass through the opening, wherein the second flange is smaller than the opening, such that it can pass through the opening.

5. Tapping assembly according to claim 1, wherein the container is a blow moulded container, preferably having a content of at least 5 litres, more preferably at least about 10 litres, especially about 10, 20 or 30 litres.

6. Tapping assembly according to claim 1, wherein the at least one closure element is a wedge, movable over at least part of the opening in the lid, between the lid and the at least one element extending from the neck, preferably having at least partly a thickness larger than a corresponding distance between the relevant side of the lid and the relevant element extending from the neck, so as to force the relevant element away from the lid, pulling the body towards the lid.

7. Tapping assembly according to claim 1, wherein the lid has a peripheral edge forming part of a closure and sealing of the pressure chamber.

8. Tapping assembly according to claim 1, wherein the container comprises a closure in and/or on the neck, comprising a valve for dispensing a beverage from the container, preferably by squeezing the boy of the container by pressurising the pressure chamber, wherein preferably the closure comprises a ring with an opening through which the valve extends.

9. Container for a tapping device, comprising a neck and a body, wherein the neck comprises a first flange extending outward and a second flange extending at least partially around the neck, wherein the first flange is closer to the body than the second flange, and the first flange extends further outward from the neck than the second flange, such that the second flange can be pushed through an opening through which the first flange cannot be pushed, wherein the facing surfaces of the first and second flanges are preferably inclined relative to each other, such that when an element is pushed in radial direction, relative to an axis of the neck against one of said surfaces, the container will be moved in an axial direction of said neck.

10. Container according to claim 9, wherein the first and second flange substantially concentrically extend around a longitudinal axis of the neck and are at least substantially circular, wherein in a view along the longitudinal axis of the neck the second flange falls within the first flange, wherein preferably the first flange has a diameter which is at least 10 millimetres larger than a diameter of the second flange.

11. Container according to claim 9, wherein the container has an internal volume over 5 litres, preferably at least about 10 litres, and the neck has an internal opening of more than 25 millimetres, preferably more than 50 millimetres, wherein a valve is provided in or on said neck, which valve preferably is mounted in or on a ring connected to the neck.

12. Container according to claim 9, wherein at least a body of the container has a wall comprising at least two layers, wherein a void can be provided between the two layers.

13. Preform for blow moulding a container, comprising a neck portion and a body portion, wherein the neck portion comprises a first flange extending at least partially around the neck and a second flange extending at least partially around the neck, wherein the first flange is closer to the body portion than the second flange, and the first flange extends further outward from the neck than the second flange, such that the second flange can be pushed through an opening through which the first flange cannot be pushed, wherein the facing surfaces of the first and second flanges are preferably inclined relative to each other, such that when an element is pushed in radial direction, relative to an axis of the neck against one of said surfaces, the preform will be moved in an axial direction of said neck.

14. Preform according to claim 13, wherein the first flange and the second flange extend substantially parallel to each other, substantially perpendicular to a longitudinal axis of the neck portion, wherein the distance between the first and second flange is smaller than a third of the average internal cross section of the neck portion, preferably less than a fourth, more preferably than a fifth, wherein the cross section is preferably more than about 25 millimetres, more preferably more than about 50 millimetres.

15. Method for tapping a beverage, wherein a lid of a pressure chamber is mounted on a neck of a container and the container is inserted into the pressure chamber, such that the lid closes off the pressure chamber at least partly, wherein the container is pulled with a first flange against a side of the lid facing the pressure chamber and locked in that position, thereby sealing an opening in the lid through which the neck of the container extends.
