Abstract

Abstract A fixture for a bag-type liquid dispenser has a bracket having an upstanding plate for attachment to a wall and from the bottom of which a shelf having a nozzle hole extends forwardly, and a cover adapted to open and close in front of the plate and shelf. The dispenser has a flexible bag in which the liquid is sealed and having a main portion in front of the plate and a dispensing portion folded forwardly on the shelf and having a dispensing nozzle extending downwardly through the nozzle hole. The cover has a forwardly extending portion covering the bag's forwardly folded dispensing portion, an opening being formed in this forwardly extending portion above the actuator, and a push button being positioned in this opening for applying pressure on the valve's actuator.
