Abstract: Device for releasing doses of matl. which will flow from a reservoir, such as a liq. soap dispenser, uses a subsidiary dose chamber made of matl. which allows flexible elastic walls to be integrated with a supporting flange or body which is essentially rigid because of differences in wall thickness. The dose chamber has a bowl profile, the base of which can be inflected by an external lever to a degree limited by an internal adjustable stop. Designed to minimise the number of components, joints and seals and associated fabrication/assembly/maintenance costs, esp. for containing fugitive chemicals such as wetting agent mixt. incorporating terpinol, phenol, alcohol or sundry esters. Examples quoted use dose chambers made of polypropylene or of polychloropene rubber, a coaxial outlet adaptor pref. also made of or having an interfacial seal of polychloroprene rubber and serving to engage an external operating lever comprising a polyamide moulding. The dose chamber may be integrated with a main reservoir body made of identical matl. or may be clamped into a body of relatively rigid matl. The connection between the main reservoir and the dose chamber pref. includes an elastic flap valve with an integral hinge. The main reservoir may discharge similar to different reagents through two or more dose chambers actuated by common or separate lever systems.
