A liquid spray apparatus having a liquid supply assembly is disclosed. The assembly has a container and a collapsible liner received within the interior of the container. Sidewalls of the liner have a plurality of annular weak portions. As liquid (e.g. paint) in the liner is dispensed, the sidewalls are folded and collapsed regularly in the longitudinal direction without irregular local transverse deformations. The uniform collapsing of the liner enables sta-ble spraying of the liquid and minimizes the amount of liquid left unsprayed.
L'invention concerne un appareil de pulvérisation de liquide ayant un assemblage d'alimentation en liquide. L'assemblage a un contenant et Une doublure pouvant s'affaisser reçue à l'intérieur du contenant. Les parois latérales de la doublure ont une pluralité de portions annulaires peu résistantes. Alors qu'un liquide (par exemple, de la peinture) se trouvant dans la doublure est distribué, les parois latérales se plient et s'affaissant de manière régulière dans la direction longitudinale sans déformations transversales irrégulières locales. L'affaissement uniforme de la doublure permet une pulvérisation stable du liquide et minimise la quantité de liquide qui reste non pulvérisée.
