Metering valve for dispensing a fluid product, having a valve body containing a metering chamber defined by a chamber insert and two annular seals, a valve seal and a chamber seal. The chamber insert has a cylindrical wall, an upper edge cooperating with the valve seal and a lower edge that cooperates with the chamber seal. A valve slides axially in the valve body between a rest position and a dispensing position, so as to selectively dispense the contents of the metering chamber, the valve being urged towards its rest position by a spring that cooperates with the valve body and with the valve. The upper edge of the chamber insert has an annular cutout formed on the radially inner side of the upper edge, so that the width of the upper edge in contact with the valve seal is always the same, whatever the width of the cylindrical wall.

At least one part of the base body is manufactured from recycled material. The output pipe is manufactured from a material different from the recycled material.

The invention relates to a hair treatment process comprising the application to the hair of a composition comprising at least one fatty substance using an aerosol device comprising:—a container containing the composition and one or more propellants, it being possible for the propellant(s) to be present in the composition or, in the container, separate from the composition,—a means for dispensing said composition comprising:—a body (3) that is open at its two opposite axial ends,—an engaging part (10) that is open at its two opposite axial ends, at least partially defining a dispensing orifice (12).

The invention relates to portable liquid supply device, mainly for water from central and other sources or for suspensions, for example pharmaceutical products and nutrient liquids. The invention can be used in household, outdoors, in the garden plots, in health care institutions, for example, for patients with dysphagia, as the source of purified drinking water or nutrient liquids, which go to a patient easily. Liquid supply device, includes raw liquid vessel, pressure generating means, liquid treating unit, comprising a lid, liquid supply means, liquid treating element and raw liquid inlet element, characterized in that is configured to supply treated liquid in portions from 5 to 100 ml, with velocity 0.5 to 10 ml/sec.

A spray canister device is provided including a canister containing a liquid product, a canister housing having an opening, a chassis element, and a tray slidably coupled to the chassis element. The canister includes an actuator cap and is positioned in the canister housing such that a nozzle of the actuator cap is positioned proximate the opening. The canister housing, and the canister positioned therein, may be engaged with the tray via at least one protruding member. Once engaged, the tray may be slidably moved along the chassis element between a retracted position and an extended position to facilitate relative movement between the canister and the canister housing to compress the actuator cap of the canister and spray the liquid product.

A freshening product is provided. The freshening product includes a pressurized plastic container having an internal gage pressure of about 414 kPa to about 1100 kPA and an aqueous freshening composition having: at least one controlled perfume raw material (“Controlled PRM”) selected from the group consisting of: (z)-1-((1r,2s)-2,6,6-trimethylcyclohex-3-en-1-yl)but-2-en-1-one; 3-(2-ethylphenyl)-2,2-dimethylpropanal; 3,7-dimethyloct-6-en-1-ol; 3-(4-isopropylphenyl)-2-methylpropanal; 5-heptyldihydrofuran-2(3h)-one; (e)-4-methyldec-3-en-5-ol; 4-(tert-butyl)cyclohexyl acetate; 2-(tert-butyl)cyclohexyl acetate; allyl hexanoate; 2,6-dimethyloct-7-en-2-ol; 2-methyl-1-phenylpropan-2-yl acetate; (z)-cyclooct-4-en-1-yl methyl carbonate; (r)-1-methyl-4-(prop-1-en-2-yl)cyclohex-1-ene; 3,7-dimethylocta-1,6-dien-3-ol; 3,7-dimethylocta-1,6-dien-3-yl acetate; 3-(4-(tert-butyl)phenyl)-2-methylpropanal; cyclohexyl acetate; p-cymene; (e)-3,7-dimethylnona-1,6-dien-3-ol; (e)-4-(2,6,6-trimethylcyclohex-1-en-1-yl)but-3-en-2-one; (e)-4-(2,6,6-trimethylcyclohex-2-en-1-yl)but-3-en-2-one; (z)-3-methyl-4-(2,6,6-trimethylcyclohex-2-en-1-yl)but-3-en-2-one; 1-(2,6,6-trimethyl-1-cyclohex-2-en-1-yl)pent-1-en-3-one; 3a,4,5,6,7,7a-hexahydro-4,7-methano-1(3)h-inden-6(1)-yl propanoate; 3a,4,5,6,7,7a-hexahydro-4,7-methano-1(3)h-inden-6(1)-yl acetate; ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate; and combinations thereof, or at least one limited perfume raw material (“Limited PRM”) selected from the group consisting of: ethyl 2-methylbutanoate; 3,5,5-trimethylhexyl acetate; ethyl 2-methylpentanoate; propyl (s)-2-(tert-pentyloxy)propanoate; 1-(3,3-dimethylcyclohexyl)ethyl formate, 4-methylquinoline; 1-heptanol; and combinations thereof, wherein each Controlled PRM or each Limited PRM, when present, is present at a level up to 0.3%, by weight of the aqueous freshening composition.

An aerosol actuator has a main body member, a nozzle member defining an outlet opening, and a selector member. The outlet opening defines a fluid flow direction. The selector member is moved to obtain different fluid spray patterns. The selector member is distal to the nozzle member and the fluid flow direction.

Aerosolizing delivery apparatuses can include cartridges configured to be detachably connected to a delivery device. The cartridges can include: a housing defining a reservoir and a cartridge outlet, the cartridge outlet configured to permit fluid communication between the reservoir and an exterior of the cartridge. A surface of the housing can be configured to define a bypass port between the housing and a surface of the delivery device when the cartridge is assembled with the delivery device.
