<p>An apparatus for combining at least two components comprising a first compartment 10 for a first component 12, a second compartment 20 for a second component 22, a valve 30 arranged between the first and second compartments separates the two components, and a pressure increasing means for increasing the pressure in the second compartment. Ideally, the second compartment is compressible and formed from a flexible or deformable material. The valve comprises a membrane or flexible material which has at least one slit. Preferably, the valve is a check value which only allows fluid flow in one direction, ideally from the second compartment to the first. The apparatus is ideally used for the controlled release of an activation reagent in to a chemiluminescent composition such that the apparatus is a glow stick. A method of operation comprises increase the pressure in the second compartment, perhaps by squeezing the second compartment, to open the valve between the compartments.</p> |
