Title (EN) DISPENSER WITH PISTON ASSEMBLY FOR EXPELLING PRODUCT
(FR) DISTRIBUTEUR A ENSEMBLE DE PISTONS DESTINE A CHASSER UN PRODUIT
Abstract:
(EN) The present invention relates to a non-aerosol dispenser. The problem associated with aerosol dispensers is that many contain hydrocarbons which contribute to air pollution. The non-aerosol dispenser comprises an inner cylinder (224) defining a material chamber (211) with a discharge valve (214) at one end. A piston assembly (220) for pressurizing the contents carries a cutting edge (288, 289) and guides (280, 281). Outer housing (240) receives the guides (280, 281) which advances the piston (220) upon rotation of the housing (240) while forcing the cutting edge (288, 289) to cut through the inner cylinder (224). The piston (220) includes an energizer member (252). An ejector (250) and spring is disposed between the energizer (252) and the valve (214). The spring stores energy from advancement of the piston (220) and transmits such to the ejector (250).
(FR) Est décrit un distributeur non aérosol. Le problème associé aux distributeurs aérosol est qu'ils sont nombreux à contenir des hydrocarbures contribuant à la pollution atmosphérique. Le distributeur non aérosol comprend un cylindre intérieur (224) définissant une chambre de matière (211), et doté d'une vanne d'écoulement (214) au niveau d'une extrémité. Un ensemble de pistons (220) destiné à mettre sous pression le contenu, porte un bord coupant (288, 289) ainsi que des guides (280, 281). Un logement extérieur (240) reçoit les guides (280, 281), lesquels avancent le piston (220) par rotation dudit logement (240) tout en forçant le bord coupant (288, 289) à traverser le cylindre intérieur (224). Le piston (220) comprend un élément amplificateur d'énergie (252). Un éjecteur (250) et un ressort sont disposés entre l'amplificateur d'énergie (252) et la vanne (214). Le ressort stocke l'énergie provenant de l'avancée du piston (220) et la transmet à l'éjecteur (250).
