Embodiment Construction

[0022] The accompanying drawings are only schematic and schematic representations, showing only the part of the keg with which the invention is related. In describing these various embodiments, like parts are indicated by like reference numerals in the drawings.

[0023] figure 1 A metal keg 1 for containing beer according to the prior art is shown. The keg 1 has a substantially cylindrical shape (circular in top view), and figure 1 is a schematic vertical sectional view. The keg 1 is equipped with a conduit 2 which passes through the upper wall of the keg. One end of the conduit 2 is connected to a tap 3, which has a handle 4 for opening the tap 3, whereby beer can flow through an outflow conduit 5 of the tap. The other end of the conduit 2 is located near the bottom 6 of the keg 1 .

[0024] Inside the keg 1 is a container 7 made of flexible plastic material, similar to a plastic bag. The container 7 can rest on the bottom 6 and the cylindrical side wall of the keg 1 ....

Abstract

A keg enveloping a container (8) for containing a beverage and means for deforming the container (8) in order to drive the beverage out of the keg (1). The container (8) comprises two substantial rigid walls (13,14), which walls are mutually connected by a flexible wall (15). The flexible wall (15) is shaped as a bellows. Said means can move the two rigid walls (13,14) towards each other, so that the distance between the two rigid walls (13,14) varies. The material of the container (8) comprises preferably a metal layer or is made of metal.

Description

technical field [0001] The present invention relates to a keg enclosing a container for containing a beverage and means for deforming the container to push the beverage out of the keg. Thus, the container is completely filled with beverage and the amount of beverage in the container, ie the capacity of the container, can be changed by deforming the container. Background technique [0002] The container can contain beer, and the drink can be any other drink. A keg can be used as a beverage dispenser whereby beverages can be dispensed directly through a tap mounted on the keg. The keg can also be a replaceable beverage holder in a beverage dispensing device, such as a home beer dispensing device. Such a domestic beer dispensing device is disclosed in WO-A-2004 / 051163. [0003] Publication WO-A-2005 / 113371 describes a keg for storing beer, equipped with a container which is a deformable bag made of flexible plastic material, whereby means for pushing the drink out of the keg...
