a squeeze bottle , useful for atomizing liquids such as perfumes , medications , insecticides , or the like , by manually squeezing the bottle while orienting the bottle to direct the resulting atomized spray for a desired application . the squeeze bottle utilizes ambient air and contains an inner , compliant pouch for storing a liquid . the pouch is configured so that it deforms by the hydrostatic air pressure generated within the bottle during a squeezing action . this deformation assists in transferring liquid from the pouch into the bottle &# 39 ; s spray nozzle where the liquid is atomized in a swirl airflow and dispersed by the expelled ambient air .
