An object of the present invention is to provide an aerosol product for forming a warming cream composition which is capable of achieving excellent dispersion stability of hydration exothermic substance powder and of easily forming a warming cream composition having a sufficient warming effect. The aerosol product of the present invention includes a double structure container provided with a discharging mechanism for simultaneously discharging contents filled in the two liquid concentrate filling spaces. The propellant filling space is filled with a propellant composed of compressed gas. The first liquid concentrate filling space is filled with a composition, which includes hydration exothermic substance powder dispersed in a liquid medium containing a polyhydric alcohol and a higher alcohol and having a viscosity (at 20° C.) of 1000 to 10000 mPa.Math.s, containing 10 to 40% by mass of the hydration exothermic substance powder, and 0.05 to 20% by mass of the higher alcohol, and having a viscosity (at 20° C.) of 1000 to 125000 mPa.Math.s. The second liquid concentrate filling space is filled with a composition containing water and 0.1 to 10% by mass of a viscosity modifier.

A dispenser for holding multiple doses of fluids or other substances, and for dispensing the substances, has a vial, a flexible bladder received within the vial, and a variable volume storage chamber formed between the bladder and vial. A filling valve is coupled in fluid communication with the storage chamber and defines (1) a normally closed, fluid-tight position hermetically sealing the storage chamber from the ambient atmosphere, and (2) an open position allowing the passage of fluid through the valve both to evacuate the storage chamber and to introduce fluid through the valve to fill the storage chamber. A pump is coupled in fluid communication with the storage chamber for pumping fluids out of the storage chamber. A dispensing valve is coupled in fluid communication with the pump and defines (1) a normally closed, fluid-tight position preventing the passage of fluid out of the dispenser, and (2) an open position for dispensing pumped fluid therethrough. The sealed, empty dispenser is sterilized, such as by applying gamma radiation thereto. Then, the sterilized, sealed, empty dispenser is filled with fluid by engaging the filling valve with an evacuating/dispensing member to evacuate the storage chamber, and by introducing fluid from the filling member through the open filling valve and into the storage chamber. The filling member is withdrawn from the valve, and a spring moves the valve to a closed position to hermetically seal the fluid within the dispenser.

A system and corresponding method for charging an aerosol can with a compressed gas charge includes a base that is adapted for receiving a can that (i) houses a product and (ii) includes a means for injecting gas, such as a grommet or valve on the bottom of the container, and includes a compressed gas source, such as a pre-charged canister of compressed air, and air compressor, and/or an automatic or manual air pump. The can may be filled with at atmospheric pressure and then shipped while the can contains approximately atmospheric pressure. Upon receipt of the can, a user may charge the can with a compressed gas and repeat charging if needed after some of the product has been dispensed.

A pumping container for blocking air comprises: a container for accommodating liquid contents; a pumping cap, coupled to an inlet of the container, for discharging the contents accommodated in the container to the outside according to a pumping operation; a suction line, coupled to the pumping cap, for sucking in the contents according to the operation of a pumping part; and an air blocking member for preventing the contents remaining in the container from making contact with air, by receiving and collecting air on the inside thereof in a volume equal to that of the contents discharged from the container by the pumping operation. Since the pumping container for blocking air, configured as described above, can always keep the contents accommodated in the container sealed from the outside so as not to be in contact with air, it is possible to prevent the problem of the shelf life of the contents rapidly shortening due to the decomposition or oxidation by contamination of the contents.

A container comprises a body of plastics material with a “bag-on-valve” arrangement. The bag depends from a valve and contains a post-foaming gel cleansing composition. A propellant is provided in the container outside the bag, so as to exert a pressure on the post-foaming gel cleansing composition in the bag, such that when the valve stem is depressed to open the valve the post-foaming gel cleansing composition is expelled through the valve stem. The container comprises a cap and the cap is provided with a conduit therethrough to guide the composition from the valve stem to an exit orifice. The conduit comprises an expansion chamber for receiving the composition from the valve stem, a neck having a smaller diameter than the expansion chamber for receiving the composition from the expansion chamber, and a nozzle provided with an exit orifice and having a diameter larger than the neck.

A valve assembly for a dispenser. The valve assembly includes a valve body that extends about a longitudinal axis and defines an outer surface and an inner passageway. The valve body includes a first valve body surface and a second valve body surface opposite the first valve body surface. A valve stem extends through the inner passageway and includes an outer stem surface, an inner stem surface opposite the outer stem surface, and a first orifice extending from the outer stem surface to the inner stem surface. A resilient member is disposed on at least a portion of the first valve body surface. The resilient member is made from a resilient polymeric material and has a non-linear compression profile.
