Device, system and method for dispensing a liquid from a container

Abstract

The invention relates to a device () for dispensing a liquid from a container (C), comprising a pump () having a suction side (S) that is adapted to be brought into fluid communication with the container (C), a spray nozzle () in fluid communication with a pressure side (P) of the pump () through an outlet channel (), a pre-compression valve () arranged in the outlet channel (), and a gas buffer () in fluid communication with the pressure side (P) of the pump () and with the spray nozzle (). The gas buffer () may comprise a buffer chamber () in which a gas-filled resiliently deformable body () is arranged, and the gas buffer () may extend from the pressure side (P) of the pump () in a different direction than the outlet channel (). The invention further relates to a system for dispensing a liquid, comprising a container (C) that is filled with the liquid and a dispensing device () of the type described above connected to the container (C). And the invention relates to a method for dispensing a liquid, comprising the steps of:—drawing the liquid from a container (C) and pressurizing the liquid by actuating a pump (), wherein the container (C) and the pump () form part of a dispensing system;—guiding a part of the pressurized liquid to a spray nozzle () of the dispensing system;—spraying the liquid from the nozzle ();—guiding another part of the pressurized liquid to a gas buffer () for temporary storage; and—spraying the stored liquid from the nozzle () when the pump () is not being actuated; wherein the pressurized liquid is guided from the pump () to the spray nozzle () in a different direction than from the pump () to the gas buffer ().
