ABSTRACT:
A dispensing device (1) with multi-arm tubing assembly (10) connected to a single source pumping means (12) draws and mixes multiple fluids from plurality of flexible walled sealed supply containers (50a,b) then expels the mixture (60) through nozzle (58) to a target surface (62). Dispensing device (1) provides a closed system whereby no venting occurs, rather supply containers (50a,b) contract in size equal to the volume of fluid expelled. Unstable fluids thus remain protected from exposure to outside air. Additionally, a new use of a repressurization device is disclosed for maintaining the potency of unstable fluids like hydrogen peroxide and a kit is provided which allows user to choose from various components and accessories as needed to suit their multi-chemical dispensing needs.
