An overcap assembly includes an actuating button attached to and surrounded by the body. The actuating button has a fluid passageway therein, and the fluid passageway is configured to receive a fluid when the actuating button is depressed. The overcap assembly further includes a first nozzle and a second nozzle. The first nozzle extends from the actuating button and is in fluid communication with the fluid passageway. The first nozzle includes a first exit aperture. The second nozzle extends from the actuating button and is positioned below the first nozzle. The second nozzle is in fluid communication with the fluid passageway. The second nozzle includes a second exit aperture angled differently than the first exit aperture. The first nozzle and the second nozzle each comprise an inner cylindrical wall and an outer cylindrical wall surrounding and spaced apart from the inner cylindrical wall.

The present invention provides a fluid medium dispensing system (1) for dispensing a fluid medium stored under pressure. The system (1) comprises a container (3) for storing the fluid medium under pressure, the container (3) comprising a neck (5) defining an opening (6). A valve cup (2) supporting a valve (4) closes the opening (6) of the container (3). Contiguous portions (14, 5) of the valve cup (2) and the neck (5) are comprised of plastics materials. The plastics materials of these contiguous portions (14, 5) are fused to form a molten weld seam (15a; 15b) by laser welding thereby sealing the container (3). Preferably, the plastics material of the neck (5) of the container (3) is laser-transparent and the plastics material of the valve cup (2) is laser-absorbing. Advantageously, the plastics material of the valve cup (2) is a semi-crystalline polymer. The invention also provides a method of assembling a dispensing system (1) for a fluid medium. In the method a valve cup (2) is provided that has at least a peripheral portion thereof that is comprised of a plastics material and that includes a valve (4). A container (3) is provided that is suitable for storing the fluid medium under pressure and that comprises a neck (5) comprised of a plastics material. The neck (5) defines an opening (6) and the valve cup (2) is positioned at the opening (5). The internal volume of the container (3) is then charged before the valve cup (2) is pressed into the neck (5) of the container (3). The plastics materials of the valve cup (2) and the neck (5) are then fused together to form the molten weld seam (15a; 15b) by laser welding thereby sealing the container (3).

A propellant free continuous dispensing device comprises an inner bag surrounded by an elastic sleeve containing fluid under pressure, a valve attached to the inner bag to controllably release fluid, the valve mounted in a mounting cup, a package enclosing the inner bag and elastic sleeve which may be of non-metallic material, a flange closing the package at one end, the flange being sized for the mounting cup to fit within the flange, and wherein the flange and the mounting cup are provided with complementary shapes to allow for location of the mounting cap into the flange.

The purpose of the present invention is to enable a metering chamber and a propellant-accommodating space region to be reliably isolated from each other at a metering valve mechanism, where contents placed in an inner bag is discharged from the metering chamber to the outside space by means of an annular piston which is moved by pressure from the propellant acting thereon and is for configuring the metering chamber, the isolation being achieved by preventing the contents loaded into the inner bag from leaking through both inner and outer edges of a contents-receiving surface section of the annular piston to a propellant-receiving surface side on the other side thereof. For example, an annular piston 8 of a bag-on-valve type metering valve mechanism is composed of a lower surface section for having act thereon the pressure from contents to be sprayed, which are loaded via a stem vertical center passage section 6a and an inner housing 3 (3a+3b), and an upper surface section disposed on the other side thereof and having act thereon the pressure from a propellant via an upper vertical hole part 4f. An inner lower-side inverted skirt-like section 8b for providing a seal with the outer peripheral surface of the inner housing 3 and an outer lower-side skirt-like section 8b for providing a seal with the inner peripheral surface of an outer housing 4 are formed at least at the edges of the lower surface section.
