Sprühbehälter

A Sprühbehälter, or spray can, is a self-pressurized container used for dispensing a product in an aerosol spray. Typically, a spray can consists of a metal cylinder containing the product, a propellant, and a valve system. When the valve is actuated, usually by pressing a nozzle, the pressurized propellant forces the product out of the can, atomizing it into fine droplets that form a spray.

The propellants commonly used are liquefied or compressed gases, such as hydrocarbons like propane and butane, or dimethyl ether. These propellants are stored under pressure within the can and, upon release, expand and vaporize, expelling the product. The product itself can be a wide range of substances, including paints, lacquers, hairsprays, insecticides, lubricants, and cleaning agents.

The design of the nozzle and valve assembly is crucial for controlling the spray pattern and droplet size, allowing for different applications. For instance, some nozzles produce a wide, fan-shaped spray for covering large areas, while others create a narrow, precise stream for targeted application. Safety considerations are paramount in the design and use of spray cans, as they contain flammable propellants and operate under pressure. Proper ventilation and avoiding ignition sources are essential when using these containers.
