Recently there has been considerable interest in systems for dispensing beverage such as beer from cans, and other small containers, which gives a similar appearance to dispensing the beverage from draught. Such an apparatus comprises a container (5, 6, 22, 32, 33) containing the beverage (4), an active surface (3, 20, 31) separated from the beverage (4), and a means for allowing the active surface (3, 20, 31) to be exposed to the beverage (4) after opening the container (5, 6, 22, 32, 33) to generate foam in the beverage (4) as it is dispensed. The active surface (31) may be separate from the container (32, 33) prior to opening, for example by being provided as a lining on the inside of a spout (30) (Figure 9 and 10). Alternatively, the active surface (3, 20) may be located within the container (5, 6, 22), but held physically separated from the beverage (4) prior to opening of the container (5, 6, 22). The active surface (20) may be included in a part of the container (22) distant from the beverage (4), for example in the neck of a bottle (22), and preferably covered by a stopper (23) (Figure 8). The active surface (5, 6) may be held physically separate by being located inside a capsule (1) which is arranged to open or rupture on opening of the container (5, 6). |
