Abstract:
A dosing dispenser for dispensing a specific amount, by weight, of a solid material into a reservoir, comprising:a funnel for receiving the solid material, the funnel having a receiving end and a dispensing end;a valve mechanism for regulating the flow of solid material from the funnel, the valve mechanism being situated at the dispensing end of the funnel;a balance beam having an attaching end and a supporting end, the attaching end being attached to a resistance spring and the supporting end, formed in the shape of a yoke, supporting the reservoir, and wherein the balance beam pivots about a fulcrum point;a gimbaled mount which rests upon the supporting end of the balance beam, the reservoir being connected to the gimbaled mount, such that the reservoir is maintained in a vertical orientation as the beam is depressed downwards;a bellows, the bellows being sealingly attached at one end to the funnel and at the other end to the gimbaled mount, thereby creating a closed system between the funnel and the reservoir; andan indicator connected to the balance beam, such that as the solid material is introduced into the reservoir, the weight of the material displaces the balance beam, which, in turn, displaces the indicator along a scale.
