Abstract: Closed loop dispensing system comprising dispenser cap 300 connectable to a container receiver 100 and valve 200A, 200B, comprising:—a cup-shaped base 210, insertable into receiver 100, having inlet aperture 214 and longitudinal tunnels 218 which house occlusion elements 260, 265,—a spring support 220 coupled to the cup-shaped base 210 and spaced apart from bottom 212 of cup-shaped base 210 and provided with spring support top sleeve 222,—a movable sealing dome 240 slidably coupled to spring support top sleeve 222 so as to define a variable volume sealed chamber housing elastic element 230,—a locking cover 250 resting on the cup-shaped base 210 and having a locking cover top sleeve 253 surrounding a hole 252, wherein an edge 256 of the hole 252 and the movable sealing dome 240 are configured to be in contact with each other by sealed interference fit when the elastic element 230 assumes the elongated configuration.

Abstract: The present disclosure relates to a selector device configured to allow a selection of a fluid in a mixing system. The overall configuration of the device being such that in an operative condition of selection of a specific fluid said one or more connection ports are translated in a sealed way on said face along said curvilinear trajectory through said manoeuvring means until an overlapping position of said one or more connection ports with respect to said outlet mouth of the inlet channel of the specific fluid, and said suction mouth of the suction channel, said outlet mouth and said suction mouth being positioned at said face.
