An insert (1) for positioning in a con- tainer of beverage such as beer which is to be sealed under pressure. In use, the insert is filled with gas and/or beverage which is released from the insert in order to gen- erate foam in the beverage when the con- tainer is opened. The insert is formed from two mouldings (2, 12) which snap together. One of the mouldings (12) is deformable between a convex and a concave configu- ration. Apertures (10a, 14) are provided in each moulding so that when the moulding (12) is in its convex configuration, commu- nication is provided via the apertures into the insert. When the moulding (12) is in its concave configuration this communica- tion is substantially restricted, leaving only a small passage (14a). In use, a jet of gas is released from the insert via this aperture in order to cause the production of foam in the beverage. The invention also extends to a method of filling the insert (1) with nitrogen gas.
