Device for measuring, dispensing and storing of granular, powder and grain materials

Abstract

A hand-operated device for measuring, dispensing and storing of powder, granular and grain materials, having filling and discharging/storing positions, comprising: a container wherein the material is stored and a measuring and dispensing unit attached to the container. In the preferred embodiment the unit includes: a housing having interconnected material receiving and material discharging openings; a slide moveable back and forth inside the passageway, delivers the material from the receiving opening to the discharging opening, accommodating a predetermined volume of the material dispensed by the device in one stroke; extensions prevent bridging of the dispensed material, a spring, being extended when the slide moves inside the housing due to an outside force applied to the slide and returning the slide into its original position after the outside force is released; a retaining apparatus holding the slide inside the housing in its discharging position when the device is not in use, a stopping apparatus fixing filling position of the slide; and apparatus providing airtight closing of the measuring and dispensing unit of possible penetration of air from the container to outside atmosphere or back. In the first embodiment the device includes extensions on the slide directed towards the container to break-up clogged material within container during movement of the slide. In the second embodiment the transporting mechanism includes also a screening mechanism capable to close or open the compartment in the slide wherein the dispensed material is received.
