Abstract

Disclosed is a method for producing a unit-dose capsule which includes optionally forming the first film into the shape of a first cavity, supercooling a first component to a temperature at which the equilibrium state of the first component is a solid or semi-solid, dispensing the first component in a supercooled state into the first cavity, such that the first component gels to form at least one layer of gel adhered to and/or in contact with the first film, forming a second film into the shape of a second cavity, filling the second cavity with a second component, sealing the first film to the second film to form a sealed cavity having at least one chamber containing the first component and the second component. The method may further include wetting and perforating the first film. The unit-dose capsule includes the sealed container and the two components.
