<p>A method for manufacturing a canister from which product is to be dispensed by means of a dispensing system comprising a solid/gas arrangement in which the gas is adsorbed on to the solid under pressure and desorbed therefrom when the pressure is released and in which the solid comprises an adsorbent for the gas and the gas comprises one or more of nitrogen, oxygen (or mixtures thereof including air), carbon dioxide, nitrous oxide and argon, the container (1) being adapted to be sealed and having valve means (7) to cause product to be dispensed by means of the pressure of the adsorbed gas, wherein the method includes filling the canister (1) with the gas by applying a pressure of gas to the adsorbent (5) for adsorption thereon via an aperture (4) in the canister (1) and sealing the canister and wherein the sizes of the aperture (4) and of the applied pressure are controlled such that sufficient gas is allowed freely to contact the adsorbent (5) and achieve a pre-determined pressure in the sealed canister.</p> |
