Abstract: A dispensing device for dispensing a foamable product. The dispensing device comprises a dispensing channel (110; 210; 410). The dispensing channel has: an inlet (111; 211; 411) for communicating with a valve-element (120) of a container (130) containing the foamable product; and an outlet (112; 212; 412) for dispensing the foamable product. The dispensing channel (110; 210; 410) further comprises a variable-volume cavity (140; 240; 440) at the outlet. The variable-volume cavity (140; 240; 440) is defined at least partly by a first component (142; 242; 442) and a second component (144; 244; 444) that is separate from and rigidly movably with respect to the first component to vary the volume of the variable-volume cavity (140; 240; 440) between a first configuration and a second configuration. In the first configuration, the variable-volume cavity (140; 240; 440) has a first volume and the outlet (112; 212; 412) is closed.

The dispensing device further comprises a latch mechanism (140; 240), configured to retain the dispensing device in the charging configuration until the metering chamber (120; 220) attains its expanded configuration. The method comprises actuating an actuator (130; 230) of the dispensing device, to fill the metering chamber, and releasing the actuator to dispense the metered dose of product.

Abstract: An outer container for an aerosol dispenser and an aerosol dispenser usable with the outer container. The outer container comprises an upper container portion and lower container portion joined at a seal. A piston slideably disposed in the outer container dispenses product under propellant pressure. The lower container portion has a base and integral sidewall with no bung hole, eliminating leakage paths.

Abstract: The invention relates to a piston for an optionally pressurized container, the piston having a sidewall, an upper side and a bottom side, and at least a first circumferential seal, wherein at least the upper side of the piston is closed by a closure and made of a first elastic material, wherein the upper side is configured to deform upon a pressure change acting on the upper side, wherein the sidewall is made of a second material which is different from the first elastic material, wherein the first circumferential seal is positioned on the sidewall on its outer surface. The invention further relates to an optionally pressurized container comprising a piston as mentioned above, to a process of discharging a product from said container and to a process of manufacturing said container.

Abstract: Disclosed is a package to dispense a composition, wherein the package comprises: a flexible inner container made of gas-impermeable material and holding the composition wherein the composition comprises a blooming agent in an emulsified liquid form; a sealed rigid outer container which encloses the flexible inner container and which is filled with a driving gas compressing the inner container; and a dispenser attached to the inner container and in a fluid connection with the composition by which the composition is allowed to be dispensed by the pressure of the driving gas; wherein the pressure of the driving gas is higher than the vapor pressure of the emulsified liquid blooming agent in the inner container, throughout the usage of the package until the exhaustion of the composition in the inner container.

Abstract: An air treatment device for the vaporization of an air freshening substance, the device comprising: a replaceable cartridge comprising a reservoir, for containing the air freshening substance, and a wick, in fluid communication with the reservoir, having a top end and a bottom end defining a wick height; a heating means for heating the wick to a predetermined temperature to vaporize the air freshening substance; a heating means support for retaining the heating means; and a housing enclosing at least the heating means and heating means support therein, and having at least one opening for allowing the vaporized air freshening substance to exit the air treatment device.

Abstract: A dispenser for viscous materials has a housing with a moveable wall that divides the interior volume of the housing into a distal product chamber and a proximal pressure chamber. An outlet from the product chamber is located adjacent to the distal end of the housing and an air inlet is provided to allow air to enter the pressure chamber. Displacement of the product occurs when accumulated excess air pressure in the pressure chamber acts on the back of the movable wall. The excess air pressure is built up by a bellows assembly arranged in fluid communication with the pressure chamber. On actuation, the bellows can be reduced in volume and subsequently recover by entry of air through the inlet. The direction of force application is preferably perpendicular to the housing axis and the location of the bellows is preferably distant from the product outlet.
