Abstract
A dosing dispenser for measuring and dispensing specific quantities, by weight, of a solid material, for example a powder or granular material, from bulk packaging to an application apparatus. The dosing dispenser includes a funnel for receiving the solid material, a valve mechanism for regulating the flow of solid material from the funnel, a balance beam, attached at one end to a resistance spring and at the other end to the application apparatus, and an indicator connected to the balance beam. As the solid material is introduced into the application apparatus, the weight of the material displaces the balance beam, which, in turn, displaces the indicator along a scale.
