  • Patent number: 4144989
    Abstract: A granular material dispenser especially adapted for the pouring of granular materials, such as soap powder, powdered milk, coffee, and the like, whereby a pre-determined amount of the material can be dispensed with each tilting and pouring so that an adequate measure of the ingredient necessary can be easily dispensed. The concept of this invention features attaching a receptacle to the package of granular material and by the use of baffles to fill a reservoir when the package is first overturned, setting the reservoir in a pouring position when the package is raised, and then dispensing the predetermined amount of granular material when the package is again overturned and the lid opened. An adjustable baffle may be provided to permit for varied measure.
