Abstract: A dispenser cap for fluid substances, including relatively movable members defining a dispensing hole and an appendix for closing the hole. When the cap is in a closed state, the cap surface in proximity with the dispensing hole is substantially smooth and uniform. When the cap is in a dispensing state, a tubular element in which the hole is provided projects from the surface.

Abstract: A fluid substance dispenser including a container defining an elongate chamber to contain the fluid substance. The container is closed at one end by a movable piston and at its other end by a transverse fixed wall from which there extends, outwards from the chamber, an elongate appendix the free end of which is positioned to correspond with a hole provided in a deformable cap defining with the fixed wall a compression chamber. The edge of the cap is elastically urged to seal against said end when the cap is in its rest state, whereas it separates partly from it when the cap is pressed to dispense the fluid substance.

Abstract: A hand pump for dispensing liquids or pastes from a bottle has a hollow, substantially cylindrical or frusto-conical body open at its two ends. The pump also has a tube fitted around its lower end which dips into the substance to be dispensed. An inlet ball valve is located within the hollow body and moves to allow the liquid or paste to be dispensed during a "draw-in" stage, but closes on termination of the "draw-in" stage to prevent the liquid or paste from returning to the bottle. A hollow coaxial stem projects from the upper end of the hollow body and has its lower end integral with a piston slidable within the hollow body. A dispenser knob which is affixed to the upper end of the stem has a dispensing channel which communicates with an inner cavity of the stem to thereby form an outlet channel for the liquid or paste. An outlet valve allows the dispensed substance to emerge when the dispenser knob is pressed.
