Abstract
Plastic squeeze bottle is provided with discharge tube as well as down tube extending from above the powder level to the lower end of the discharge tube. Baffle is disposed at the lower end of the two tubes. During dispensing, squeeze of the bottle increases air pressure above the powder which drives air down through the powder and drives air down down tube to fluidize powder on the baffle from whence it moves upward through discharge tube to discharge.
