Abstract: The invention relates to a dispensing closure for a container that holds a fluid, which can be tightly fitted into a container neck to ensure liquid-tightness of the container. The dispenser closure includes a plug body arranged to be inserted into the container neck and having a central fluid passage and having a peripheral air passage, a double-valve diaphragm comprising a flexible elastic material and arranged in a recess provided in an upper part of the plug body to cover the fluid passage and the air passage, and a plug cap sealing the double-valve diaphragm within the plug body having one or more slots arranged circularly and axially aligned with the air passage of the plug body and having a central orifice axially aligned with the fluid passage of the plug body. The double-valve diaphragm comprises a first valve section, and a second valve section.

Abstract: A liquid droplet spray device for ejecting a liquid as a spray of droplets has a cartridge (15) with a nozzle arrangement (13) to eject droplets, which is vibrated by a piezo element (23a) through the agency of an actuating element (23). A resonance chamber is disposed between an inner wall (15a) of the cartridge and the actuating element (23) such that the cartridge inner wall (15a) is separated by a gap having a length B from the actuating element (23), the cartridge inner wall (15a) being cap-shaped and extending along the side surfaces of the actuating element (23) and being frictionally attached to the side surfaces along a distance A. The resonance chamber (10) improves the efficiency of transmission of vibrations to the cartridge.

Abstract: A watertight fragrance dispensing device for ejecting fragrance as a spray of droplets, the device including: a spray head for ejecting fragrance from the device; a liquid reservoir arranged to provide the fragrance to the spray head, wherein the reservoir includes a primary reservoir (31), a secondary reservoir (34), and a capillary liquid feed (33) connecting the liquid reservoir to the spray head, wherein the device further includes a bottom housing; and electronic control means arranged in the bottom housing for controlling the dispensing of fragrance from the device, wherein the secondary reservoir is disposed in the primary reservoir and is in direct contact with the capillary liquid feed, wherein the secondary reservoir is smaller than the primary reservoir and contains a unit dose of fragrance to be ejected from the device.
