A dispenser

A dispenser for containing and dispensing substances such as fluids, viscous substances and/or adherent substances, the dispenser comprising:

• a flexible bag adapted to contain a substance to be discharged, a one-way output nozzle that is in sealed communication with the interior of the bag and is adapted for discharging the contents of the bag;
• a substantially impermeable receptacle, the bag being arranged within the receptacle and the receptacle being sealed with fluid being trapped between the exterior of the bag and the receptacle, the nozzle being arranged on a surface of the receptacle;
• a one-way fluid intake valve arranged on the receptacle for intaking fluid into the receptacle and around the exterior of the bag, and;
• a means for preventing the bag from blocking the nozzle, wherein the receptacle comprises a cap and a main body and wherein the cap is at least partially removable from the main body of the receptacle, and wherein the nozzle and the fluid-intake valve is disposed on the cap, wherein the dispenser comprises a fluid travel pathway to permit transfer of fluid into and/or throughout the receptacle, wherein the fluid travel pathway permits transfer of fluid from outside the dispenser through the fluid-intake valve, into the receptacle and around the exterior of the bag, wherein the fluid travel pathway comprises a fluid transfer means between the fluid-intake valve and the main body of the receptacle, and wherein the fluid transfer means permits transfer of fluid from the fluid-intake valve to at least one aperture on the receptacle when the cap is arranged on the main body, and wherein the fluid travel pathway comprises an inner-receptacle fluid travel means located on the inside of the receptacle, the inner receptacle fluid travel means being operable to permit free movement of fluid around the interior of the main body of the receptacle even when the main body contains contents such as the bag, the inner-receptacle fluid travel means comprising at least one groove, channel and/or tube, and wherein the inner-receptacle fluid travel means extends from the aperture of the receptacle along the main body of the receptacle.
