MULTI-COMPONENT DISPENSER WITH SELF-PRESSURIZATION SYSTEM

摘要

The invention relates to a gas-generating and dispensing apparatus (10) for products such as multi-component foams. A gas-generating master container (25) forms the gas when material from trigger (24), i.e. potassium carbonate, combines with a charge of mild acid (50), i.e. citric acid. The gas pressurizes the material in the product-retaining master cylinder (26), forcing the materials that form the foam to exit through hoses (32) and out of the apparatus through dispensing gun (34).
