Abstract

Abstract Dispensing apparatus is described for dispensing a first component (8) and a second component (10). The components (8, 10) are stored within a flexible container (2) and a common outlet chamber (28) is provided to receive the components when they are expelled from the container (2). The outlet chamber (28) has mixing means (32) which mixes the components (8, 10) to form a reactive mixture. Typically, the components (8, 10) are expelled from the container (2) by compression means which applies a compression force to the container. The apparatus may also comprise a housing in which the container (2) is located and the compression means may comprise a piston (24). Typically, the container (2) comprises an outer container (2) and an inner container (4) located within the outer container (2).
