Abstract
Abstract A squeeze bottle containing a powdered product such as conventional talcum powder and the like, has a construction such that when the bottle is upright and the powdered product is compacted in the bottom, a carrier stream of air is introduced to the product when the bottle is squeezed, to break up the compacted product for discharge through a dispensing orifice with which the bottle is provided. When the bottle is inverted, the construction is such that again a carrier stream of air, when the bottle is squeezed, is discharged through a fed stream of the product for dispensing by the squeeze bottle.
