Device, System And Method For Dispensing A Liquid From A Container

Abstract A device (1) for dispensing a liquid from a container (C), comprising a pump (2) having a suction side (S) that is adapted to be brought into fluid communication with the container (C), a spray nozzle (3) in fluid communication with a pressure side (P) of the pump (2) through an outlet channel (4), a pre-compression valve (5) arranged in the outlet channel (4), and a gas buffer (9) in fluid communication with the pressure side (P) of the pump (2) and with the spray nozzle (3) and comprising a gas-filled resiliently deformable body (11) extending away from the outlet channel (4) from the pressure side of the pump (P). The invention further involves a method for dispensing a liquid, comprising: - actuating a pump (2) to draw liquid from a container (C) and pressurize the liquid as part of a dispensing system; - guiding a part of the pressurized liquid to a spray nozzle (3) of the dispensing system; - spraying the liquid from the nozzle (3); - guiding another part of the pressurized liquid to a gas buffer (9) for temporary storage; and - spraying the stored liquid from the nozzle (3) when the pump (2) is not being actuated; wherein the pressurized liquid is guided from the pump (2) to the spray nozzle (3) in a different direction than from the pump (2) to the gas buffer (9).
