Abstract: A metering device for fluid products, having a pump body (1) equipped with suction tube and applied by means of a cap (2) to a bottle or the like containing a fluid product to be dispensed, an elastically deformable pushbutton, applied superiorly to the pump body (1) and defining therewith a metering chamber provided with an intake valve and an exhaust valve, a dispenser (4) mounted on the cap (2) and provided with a spout (7) comprising a conduit (70) for the emission of the content of the bottle communicating with the intake valve, at least a compensation channel, which replaces the extracted fluid with air coming from the exterior, provided, in said dispenser (4), pusbutton (3) and pump body (1).

Abstract: The present invention relates to a container reducible in size during use, with dispenser spout fitted with check valve. It comprises a bellows bottle, presenting, at one of its ends, a closed bottom and, at the opposite end, a neck destined to receive a dispenser spout fitted with a check valve with mushroom-shaped shutter. The bellows bottle is positioned inside a container with variable volume, constituted by two hollow cylinders able coaxially to slide one inside the other, the neck passing through the outer cylinder.

Abstract: The present invention relates to a micropump for the nebulization of fluids with enhanced metering valve. The micropump comprises a hollow body and a set of stem and piston such as to constitute a "metering chamber" in the body. The hollow stem, which exits the body, is joined with a dispensing push-button fitted with a nebulization element. Pressing the dispensing push-button allows the passage of the fluid to be nebulized from the "metering chamber" to an exit duct, comprising the longitudinal cavity of the stem, a "compression pre-chamber" in the dispensing button and passages from the chamber to the nebulization element. The metering valve is obtained by interposing, in said fluid exit duct, an elastically deformable shutter.

Abstract: The present invention relates to an enhanced micropump for the nebulization of fluids. The micropump, mounted on a bottle cap, comprises a hollow body and a set of stem and piston such as to constitute a "metering chamber" in the body. The set, protruding outside the body, is joined with a dispensing push-button fitted with a nebulization element. Pressing the dispensing push-button allows the passage of the fluid to be nebulizer from the "metering chamber" to an exit duct for the fluid itself, comprising a "compression pre-chamber" in the dispensing button and passages from the chamber to the nebulization element. A metering valve is obtained by interposing, in said fluid exit duct, an elastically deformable shutter positioned in a cylindrical seat in the top end of the set.

Abstract: A manual liquid dispenser (1) for a liquid dispensing bottle (3) is held fast to the threaded bottle neck (5) by a ring nut (4). The hollow pump body (6) includes inside the top end a folded-back lip (16) with an inverted V cross section. The V cross section has inclined outer (16a) and inner (16b) portions; the inner side of each is in circumference contact with one side of the bottle mouth rim (2). The folded-back lip (16) may have a flat bottom (16c) between the inner and outer portions. The outer portion preferably is inclined, making a conical surface that engages the internal lateral profile (4a) of the ring nut (4). The pump body (6) has a check valve (9) at the first end (7). An outflow push-button (11) is mounted on the end of a movable hollow stem (10) which protrudes through the second end (8) of the pump body. The stem drives a piston (12) within a pressure chamber (14).

Abstract: The invention relates to a sleeve (1) for the fixing of a pump (2) to a bottle with a neck (3) enlarged at the mouthpiece (4). The upper part (1a) of the sleeve (1) has tubular elements: one external tubular element (10) for receiving a metallic covering (5) and an internal tubular element (11) for receiving and restraining the pump (2), and a base transversal element (12) resting on the mouthpiece (4). An annular gasket is interposed between the base transversal element (12) and mouthpiece (4). The lower tubular part (1b) of the sleeve is to be inserted onto the mouthpiece (4) and is held in place in an undercut (4a) by means of rounded projecting parts (16) shown internally by the part (1b). The lower tubular part (1b) is provided with a plurality of external facings (15). The part (1b) also has externally a plurality of step projections (20) between the facings (15).

Abstract: A dispenser (10) for dispensing, liquid substances or substances in the form of cream or paste, comprising a pump (1) in which in addition to the non-return valve (17), the elastic structure for returning the piston (3) into its rest position following the operation of the dispensing knob (10) are also of plastics material, and consist of a skirt (4A) which deforms elastically when the knob (10) is pressed. To make the dispenser (10) completely salvageable, all its constituent elements are of one and the same plastics material, which is of a type from which both substantially rigid pieces and substantially elastically deformable pieces can be formed. Such a plastics material is for example polyethylene.
