A portable apparatus for dispensing and foaming of a product, including: a product container which contains a product that is to be foamed by and dispensed from the apparatus; a gas container, at least containing a gas, for example a single gas or a gas mixture, wherein the gas substantially does not contain any greenhouse gases such as N20; a dispersion device, having a product entrance that is connectable to the product container for receiving product, the dispersion device further being connectable to the gas container for supplying the gas to the product during product discharge; a processing device downstream of the dispersion device for performing a mixing treatment and/or pressure reduction on the product provided with the gas; and a product dispensing head, being part of a top section of the apparatus and being arranged downstream of the processing device.

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 portable apparatus for dispensing and foaming of a product, including: a product container which contains a product that is to be foamed by and dispensed from the apparatus; a gas container, at least containing a gas, for example a single gas or a gas mixture, wherein the gas substantially does not contain any greenhouse gases such as N.sub.2O; a dispersion device, having a product entrance that is connectable to the product container for receiving product, the dispersion device further being connectable to the gas container for supplying the gas to the product during product discharge; a processing device downstream of the dispersion device for performing a mixing treatment and/or pressure reduction on the product provided with the gas; and a product dispensing head, being part of a top section of the apparatus and being arranged downstream of the processing device.

Systems and methods are disclosed that include a spraying apparatus having a hand held spraying device, a flexible reservoir connected in fluid communication with the hand held spraying device and worn on the body of a user of the spraying apparatus, and a pressure device that provides pressure to the flexible reservoir to move fluid from the flexible reservoir to the hand held spraying device.

In accordance with an example embodiment, there is disclosed herein a sprayer operable to dispense fluid from a fluid reservoir, such as a paint reservoir. The sprayer comprises a rechargeable battery pack that can be employed to provide power to a pump. The pump provides air to a nozzle assembly that is mixed with fluid from the fluid reservoir and dispensed via the nozzle assembly. In particular embodiments, the nozzle assembly comprises a disposable tip insert.

A dry fogging system includes a control device including a control device inlet configured to couple to a gas source, a first control device outlet, and a second control device outlet configured to couple to a first tank. The dry fogging system further includes a first spray device including a first spray device inlet configured to couple to the first tank, a second spray device inlet configured to couple to the first control device outlet, and a spray device outlet configured to provide dry fogging.

A compressed air foam mixing system that has a mixing device connected to a discharge port of a tank. The mixing device receives fluid from the tank and pressurized air from the tank or alternatively directly from a source of pressurized air. The fluid and pressurized air are combined within the mixing device to form a foam.

Pneumatic spray gun (10) and cartridge tip assemblies for applying sprayable materials to various surfaces are disclosed. A tube of flowable texture material to be sprayed having a cartridge tip (100) may be loaded into a pressure canister of a texture material spray gun (10). The cartridge tip (100) may include radially outwardly extending ribs (130), radially inwardly extending recesses and/or other features that engage with corresponding features of the spray nozzle assembly to reduce or prevent relative rotation between the cartridge tip (100) and the spray nozzle assembly.

A disinfecting device is easy to use and can be easily mounted or removably connected in a dental operatory or other similar environment. The device can include a removable solution chamber attached to a base unit. The solution chamber can be a refillable chamber or a disposable chamber. The base unit can receive pressurized air, typically from a standard connection present in the dental operatory, or a dental chair, or the like. The pressurized air can be used to deliver a mist or an electrostatic fog of the solution in the solution chamber out of a nozzle. The solution bottle can be directly attached to the nozzle/sprayer device, with an air hose extending therefrom. In use, the user can turn on the system and use an activation/deactivation mechanism to deliver the atomized mist or fog to all surfaces in the room.
