Abstract
Abstract A foam spray for beauty treatment comprising a spray main body having a mount for attaching a container containing a beauty treatment solution, a gas cylinder mounted in the spray main body, a gas flow regulator including a knob member for operating a valve on the gas cylinder, and a gas flow regulator sliding member coupled to the knob member. The gas flow regulator regulates the flow of gas into the container to adjust the rate of generation of the foam to be applied.
