ABSTRACT A squeeze bottle containing a liquid product such as antiperspirant and the like, has a dispensing nozzle internally forming a swirl chamber having opposed orifices each having its own inlet. One inlet is connected with a dip tube that dips into the liquid when the bottom is upright, and the other inlet connects with an air space above the liquid when the bottom is upright. When the bottle is squeezed, the swirl chamber receives opposed jets of the liquid and air, producing an atomized spray. When the bottle is inverted, the dip tube opens into the air space formed in the bottom of the inverted bottle, while the other inlet is connected with the liquid so that again opposed liquid and air jets enter the swirl chamber. However, to prevent the liquid component in the swirl chamber from being excessive relative to the air component, the inlet now receiving the liquid is provided with a check valve which closes when the bottle is inverted while providing for a restricted flow rate of appropriate proportioning relative to the air received through the dip tube. During upright operation, the check valve opens so that the flow of air is also in this instance appropriately proportioned rela- tive to the flow of liquid.
