Patent ID: 11471901

Abstract:
A dispenser for containing and dispensing substances such as fluids, viscous substances and/or adherent substances. The dispenser has a flexible bag adapted to contain a substance to be discharged, and a one-way output nozzle that is in sealed communication with the interior of the bag for discharging the contents of the bag. The dispenser has a receptacle, with the bag being arranged and sealed within the receptacle thereby trapping fluid between the exterior of the bag and the receptacle. The nozzle of the dispenser is arrangeable on a surface of the receptacle and there is additionally a one-way fluid intake valve arranged on the receptacle for intaking fluid into the receptacle and around the exterior of the bag. The dispenser further has an arrangement for preventing the bag from blocking the nozzle. The contents of the bag can be emptied through the nozzle without the bag blocking the nozzle in use.
