CA 2111866

2111866 9222495 PCTABS00018 A spray dispenser comprises a container (12) in which a product-containing bellows (80) is situated above an energy storing bellows (82). A piston (70) is disposed within the container (12) below the energy storing bellows (82). A sleeve (40, 42) surrounds the container and is threadedly connected with the piston (70) where by rotation of the sleeve (40, 42) relative to the container (12) causes the piston (70) to rise and compress the energy storing bellows (82). The energy storing bellows (82) thus pressurizes the product-containing bellows (80) to expel the product when the valve (60) is opened. The outer diameter of the bellows (80) is of progressively reduced diameter to enable the bellows segments to become more snugly nested within one another when collapsing.
