A spray dispenser is provided, the spray dispenser comprising a container for holding a liquid to be dispensed and a dispensing assembly for extracting liquid from said container, the dispensing assembly comprising a pressure-relief valve for release of excessive pressure in the container and a filter arranged to permit egress of gas through the filter, inhibit egress of liquid from the container and to inhibit ingress of contaminants into the container through the pressure relief valve. A dispensing assembly for use is a spray dispenser is also provided.

A nebulizer for nebulizing a fluid and a reservoir with a fluid are proposed. The reservoir includes a collapsible bag with the fluid, where the bag extends in a circumferential direction within the housing part and wherein the reservoir is manually rotated for tensioning the nebulizer.

An accessory device for a wall-mounted dispenser is described. The accessory device may also be attached to the wall and may include a plate having an underside surface shaped to generally match the top edge of the dispenser and a portion of a left side edge and a portion of a right side edge of the dispended so that when the dispenser is mounted to the wall and in a closed position and the rear surface of the plate is generally parallel to and coupled to the wall, the dispenser is able to be opened and closed while tampering to the top edge and portions of the side edges of the dispenser is prevented.

Embodiments of the invention relate to dosing dispensers and in particular to dosing dispensers that may be operated using one hand by raising and filling a dosing chamber followed by lowering and dispersing a product from the dosing chamber and wherein the dose may be selected or adjusted and a user may visually confirm that the proper dose is being loaded and delivered by the dispenser.

A device for packaging and dispensing a generally fluid product includes a dispensing head placed on top of an external body into which is inserted an internal container that forms a reservoir and is suitable for rigid attachment to a metering assembly of the head. The metering assembly, of the airless type, includes a metering pump that is surrounded and supported by a closing element in direct contact with the upper end of the container in a leaktight annular connection area. A ring which surrounds the connection area covers an internal peripheral volume defined between the body and the container. A wall that is movable towards the pump inlet provides a leaktight separation and maintains an identical pressure between the product in the reservoir and the air in the peripheral volume.

A fluid dispensing device having a flexible fluid pouch and a dispensing assembly, the dispensing assembly having a top piece and a bottom piece, the top piece having a flexible actuator including a flexible dome and a flexible flange extension, the bottom piece having a bottom portion of a pump chamber, a pump chamber inlet, a chamber inlet valve, and a bottom portion of an outlet valve, the top piece and the bottom piece mated together to form a pump chamber and an outlet valve, said device configured to allow bidirectional fluid flow through either or both inlet and outlet valves, and to dispense a volume of fluid that is less than the volume of said pump chamber. The flexible pouch may have a single opening or two openings. In the case of a single opening, the entire dispensing assembly is in the interior of the pouch. In the case of two openings, only the flexible dome extends to the exterior of the pouch. The outlet valve is configured so that the more pressure that is applied to the flexible fluid pouch, the more tightly the outlet valve seals.

A device for dispensing a fluid, including a pocket whose interior volume is delimited by a deformable wall; a pressing surface; a dispensing part including a dispensing cavity; an outlet; a dispensing orifice connecting the pocket to the dispensing cavity; and a dispensing valve located in the dispensing cavity.

A nebulizer for nebulizing a liquid from a container includes a fluid pump for withdrawing the liquid in doses from the container and pressurizing the respective doses for nebulization. The nebulizer includes in addition an air pump with a piston/cylinder arrangement for pumping air into the container to pressurize the liquid in the container to help withdrawing the liquid from the container.

A dispenser includes a body having a an exterior surface, an interior surface, a first chamber, a first opening in fluid communication with the first chamber and extending through the body, a second opening in fluid communication with the first chamber and extending through the body, a first valve and a second valve disposed on the body, the valves having a closed and an open configuration, and an actuator disposed at least partially within the first chamber. The actuator may be configured to increase and decrease pressure in the first chamber such that the first valve and the second valve change from their respective closed configurations to their respective open configurations and from their respective open configurations to their respective closed configurations. When in the closed configuration, flow through the valves is impeded.
