Liquid or powdery fluid product e.g. pharmaceutical product, diffusing closure, has orifice arranged opposite to inner seating face of ring and separated below face in top and bottom positions of tubular hollow part of slide, respectively

摘要

The closure (10) has a tubular sealing and a guiding ring (14) that is fit in a neck (16) of a bottle (12). A slide (22) has a tubular hollow part (24) having an inner housing (18) communicating with a periphery through an orifice. The part (24) is mounted movable in the ring between a closed top position and a bottom position. The orifice is arranged opposite to an inner seating face (28) of the ring in the top position. The orifice is separated below the face to permit liquid or powdery fluid product to flow in the bottle by gravity through the orifice in the bottom position.
