A vaporizer device may include a vaporizer body configured to couple with at least one vaporizer cartridge including a first reservoir and a second reservoir. The vaporizer device may include a first aerosol generation mechanism configured to generate a first part of an aerosol by at least vaporizing a first aerosol component present in a first vaporizable material in the first reservoir. The vaporizer device may also include a second aerosol generation mechanism configured to generate a second part of the aerosol by vaporizing a first aerosol component present in a second vaporizable material at a second temperature. The first part of the aerosol and the second part of the aerosol may be delivered, via a mouthpiece, to a user of the vaporizer device.

An electronic smoking device includes a liquid supply (34) and an atomizer in a housing. The liquid supply (34) includes at least two container members (34a, 34b) attachable to one another through a connection mechanism to form a liquid supply main body. Each of the container members (34a, 34b) may have an outlet (341a, 341b) sealed by a sealing member (342a, 342b) and a second end which is closed, and an aerosol channel (343a, 343b) formed between the container members.

Handheld gas spray systems for mixing and dispensing multi-component compositions.

A spray nozzle for spraying material includes an outlet, a mixing section, an inlet for the material, and a buffer space for pressurized gas. The mixing section is in fluid communication with the outlet. The inlet is in fluid communication with the mixing section. The buffer space is in fluid communication with the mixing section via two or more separate gas supply channels. The inlet comprises a separating wall configured to divide a flow of material to be sprayed into two separate flow passages prior to entry into the mixing section.

A fragrance dispensing system includes a first and a second container each having a main tube for the expulsion of a fragrance contained therein, and a dispensing device that provides a dispensing path towards an outlet section and that includes a mixing chamber and a first and second auxiliary tubes connected at one end to the mixing chamber. A containing case forms a seat containing the first and second containers, and a cap is configured to be applied on the containing case and houses the mixing chamber, an outlet section for the mixed fragrances and, at least partly, and the first and second auxiliary tubes, each of which has a free end separably connected to one of the main tubes when the cap is engaged to the case.

A container unit including a plurality of container sub-portions (4) defining a plurality of chambers for containing a liquid substance, each container sub-portion including an outlet, the container unit further including a conduit device (12) serving to connect each of the outlets of the respective sub-portions to an outlet nozzle (8a). In one embodiment, a spray cycle is disclosed having first and second periods of flow allowance and purging respectively. In another embodiment, respective sub-portion (4) controllable liquid displacement devices for dispensing one or more of the liquid substances selected from one or more of the respective sub-portions (4) are disclosed.

A portable chemical dispenser for dispensing a chemical with a diluent includes a valve housing having a valve with an opened position and a closed position, an eductor housing coupled to the valve housing and including one or more eductors, and a nozzle coupled to the eductor housing and configured to direct the flow of a chemical solution to a receptacle, wherein the joint between the valve housing and the eductor housing permits relative rotations between the two housings. The portable chemical dispenser may also be devoid of metering elements that control the dosing of the chemical. A method of using the portable chemical dispenser is also disclosed.

A mix on exit sprayer having a water tank and a body the includes a chemical cartridge receiving cavity. A pump move water from the tank to a mixing chamber and a piston drives chemical concentrate from the cartridge into the mixing chamber. A venturi style mixing element mixes the water and concentrate and the pump moves the mixed fluid from the mixing chamber to a spray wand from which it can be expelled.

A foam sprayer includes a body defining a channel, a nozzle, and an adapter configured to releasably attach to a first fluid source that provides a first fluid at a first pressure. The foam sprayer includes a connector attached to the body and configured to releasably connect the body to the adapter or to a second fluid source that provides a second fluid at a second pressure that is substantially greater than the first pressure. The foam sprayer also includes a mode selection device configured to switch the foam sprayer between a low-pressure mode and a high-pressure mode. The foam sprayer is configured to generate foam from the first fluid when the foam sprayer is in the high-pressure mode. The foam sprayer is configured to generate foam from the second fluid when the foam sprayer is in the high-pressure mode.

Assembly comprising a spray means, preferably an airbrush comprising a pickup chamber subjected to a stream of entrainment air, and a dispenser comprising at least two compartments containing different base products, the compartments being pressurized by way of volumetric dosing devices, and the products being delivered to the spray means preferably via distinct dispensing orifices.
