, that is powered by
squeezing the container by exerting pressure with the user's hand. Its fundamental characteristic is that manual pressure applied to a resilient hollow body is harnessed to compress fluid within it and thereby expel the fluid through some form of
nozzle
A nozzle is a device designed to control the direction or characteristics of a fluid flow (specially to increase velocity) as it exits (or enters) an enclosed chamber or pipe (material), pipe.
A nozzle is often a pipe or tube of varying cross ...

s, it is the main body of the container that is squeezed. While
atomizers fit the basic pattern of squeeze bottles, they differ from those typical examples in that the squeezed component compresses and propels air, whose
interaction with a volatile liquid inside a rigid container then entrains and dispenses a mist of the liquid.
