The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed canister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

The object of present invention is to provide a chemiluminescent aerosol product that can easily form an expected quantity of a chemiluminescent composition which exhibits excellent storage stability, is stably self-held for a long period of time and achieves a good luminous effect.

This aerosol product includes a double-structure container provided with a discharging mechanism for simultaneously discharging contents filled in two liquid concentrate filling spaces. A propellant filling space is filled with a propellant composed of a compressed gas, a first liquid concentrate filling space is filled with a first liquid concentrate composition containing an oxalic acid ester, a fluorescent substance and a thickener, and having a viscosity of 10,000-200,000 mPa.Math.s (20 C.), and a second liquid concentrate filling space is filled with a second liquid concentrate composition containing hydrogen peroxide, a hydrogen peroxide decomposition catalyst and a thickener, and having a viscosity of 10,000-200,000 mPa.Math.s (20 C.). The discharging mechanism includes a mixture discharging member having mixer for mixing the two kinds of liquid concentrate compositions. The two kinds of liquid concentrate compositions are mixed to form a chemiluminescent composition.

A container includes a reservoir holding a non-pressurized product. A metering device and valve assembly are within the reservoir. The valve assembly includes a product intake conduit and a spring biased valve stem. The valve stem is at least one of an upwardly extending conduit or reciprocating conduit, which is in fluid communication with the product intake conduit.

A substance dispensing system including a first pressure vessel defining a first interior space; a first substance positioned in the first interior space; a first portion of a first propellant positioned in the first interior space; and a first portion of a second propellant positioned in the first interior space. At least 90 percent by weight of the first propellant is at least one of carbon dioxide, nitrous oxide, and combinations thereof. At least 90 percent by weight of the second propellant is at least one of nitrogen, argon, helium, oxygen, and combinations thereof.

The present disclosure relates to an aerosol delivery device filling system. The system includes multiple source containers each respectively including a differing aerosol precursor composition. The system further includes a mixing container configured to engage the source containers to receive and mix the aerosol precursor compositions to form a mixed aerosol precursor composition. An aerosol delivery device may engage the mixing container to receive at least a portion of the mixed aerosol precursor composition. A related method for customizing an aerosol precursor composition is also provided.

The present disclosure provides a feeding container device, including a bottle body having a bottle inner cavity, a first cover body at least partially disposed inside the bottle inner cavity and fixedly connected to the bottle body, a second cover body at least partially disposed inside the bottle inner cavity and having a cover inner cavity, a sealing ring disposed inside the bottle inner cavity and blocking the cover inner cavity, and a feeding device fixedly connected to the second cover body, the second cover body is mounted to the bottle body, the sealing ring is detachably connected to the second cover body and abuts the first cover body; when the second cover body moves away from the bottle body, the first cover body causes the sealing ring to separate from the second cover body, and the first sealed chamber communicates with the second sealed chamber.

The present invention has as its object the provision of an aerosol product for forming a cooling gel composition for the human body. The aerosol product can easily and stably form a cooling gel composition for the human body which has high storage stability and which provides comfort during use and a sufficient cooling effect. The aerosol product for forming a cooling gel composition for the human body of the present invention has a double-structure container including a propellant filling space and two liquid concentrate filling spaces and having a discharging mechanism for simultaneously discharging the contents filled in these two liquid concentrate filling spaces. The propellant filling space is filled with a propellant composed of a compressed gas. A first liquid concentrate filling space is filled with a first liquid concentrate composition containing a hydrated endothermic substance dispersed in a liquid medium. A second liquid concentrate filling space contains a second liquid concentrate composition containing water. The first liquid concentrate composition and the second liquid concentrate composition, which have a viscosity of 1,000 to 125,000 mPa.Math.s at a temperature of 20 C., are mixed to form a cooling gel composition for the human body.

A hair cosmetic material includes a first agent containing an alkali agent and a second agent containing an oxidizing agent. These first agent and second agent are used in a double structure container provided with a mechanism of separating the first agent and the second agent from each other and simultaneously discharging the both agents by a propellant. In the double structure container, a space for filling the first agent and a space for filing the second agent are each independently provided in the inside of a compressed gas filling space having a propellant for pressurization filled therein. Each of the first agent and the second agent is discharged in a liquid state, and each of the first agent and the second agent has a viscosity falling within the range of from 7,000 to 30,000 mPa.Math.s at 25 C.
