Apparatus including (a) a substantially rigid container defining at least one inlet port and at least one outlet port, and being sized and configured to define a first volume for receiving a liquid, solid particulate or slurry material; (b) a flexible, substantially non-porous bag which forms a bag opening perimeter in sealed attachment to the container at the inlet port and being in an initial deflated state; and (c) a vacuum pump in fluid communication with the rigid container through said outlet port, wherein during operation of the vacuum pump, a vacuum is created within the rigid container to thereby cause the bag in an initial deflated state to expand and form a vacuum within the bag to draw material through the inlet port and into the bag.
L'invention concerne un appareil comprenant (a) un contenant sensiblement rigide définissant au moins un orifice d'entrée et au moins un orifice de sortie, ce contenant étant calibré et conçu pour définir un premier volume destiné à recevoir un liquide, un matériau particulaire solide ou une boue, (b) un sac flexible, sensiblement non poreux qui forme un périmètre d'ouverture de sac fixé de façon hermétique au contenant au niveau de l'orifice d'entrée et étant dans un état initial dégonflé, et (c) une pompe à vide en communication fluidique avec le contenant rigide à travers l'orifice de sortie. Durant le fonctionnement de la pompe à vide, un vide est créé dans le contenant rigide pour provoquer ainsi le gonflement du sac initialement dégonflé, et former un vide dans le sac pour aspirer du matériau à travers l'orifice d'entrée dans le sac.
