This application describes a sprayer assembly that can attach to a variety of different types of pre-filled, fluid containers (e.g., non-pressurized fluid containers) for holding the fluid to be sprayed. For example, the sprayer assembly can include a sprayer-head assembly for attaching to a container of fluid, a canister for holding the container of fluid, or any combination thereof In addition, the sprayer assembly can be connected to a variety of different types of pressurized air sources. The sprayer-head assembly can include a nozzle assembly (e.g., fluid uptake tube, valve, and nozzle head), as well as a trigger for actuating the nozzle assembly.

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 The filling member is withdrawn from the valve, and a spring moves the valve to a closed position to hermetically seal the fluid within the dispenser.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.

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.

A two aerosol can injection system has a first aerosol can which contains activator or hardener and a second aerosol can containing product such as paints, thinners, clear coats, and propellant. A connector system connects at a first end to the first aerosol can and at a second end to the second aerosol can which provides flow of activator or hardener from the first can to the second can.

A method of assembling a tubular simulated cigarette, the method comprising providing an elongate hollow housing having an inhaling end and a refill end; inserting an outlet valve tube, a dip tube and a support from the refill end so that the support supports the proximal end of the dip tube in the housing; inserting a refill valve into the refill end and fixing it in place to form a composition reservoir with the dip tube placing the reservoir in fluid communication with an outlet orifice when the outlet valve tube is open; inserting a valve element into a recess in the side of the housing so that the valve element is positioned to selectively close the outlet valve tube; inserting a breath operated valve actuation mechanism laterally into the recess; and applying a cover to the recess.

An aerosol product comprising an aerosol container comprising a container body and an aerosol valve fixed to an opening of the container body, and an aqueous concentrate and a propellant being filled in the aerosol container, wherein the aqueous concentrate comprises an active ingredient having reactivity with oxygen, and an inert ingredient is present in at least a part of an injection passage of the aerosol valve, even though the aqueous concentrate comprising an active ingredient having reactivity with oxygen is filled, oxidation of the active ingredient is inhibited in the aerosol valve, and an aerosol product that can be stored stably for a long period of time and a method for manufacturing the same can be provided.
