ABSTRACT:
A container for dispensing measured quantities of free flowing material such as powders which is designed to be manufactured from a single blank of cardboard.
The operation of the container is controlled by two generally parallel baffles spaced from each other and at an acute angle to the bottom of the container. The first baffle defines the measuring chamber between its lower end and the bottom of the container. The second baffle overlays the first baffle and defines a passageway from which material can be conducted to the measuring chamber when the measuring chamber is to be loaded and from which excess material can be returned to the container when the material is dispensed.
