Bead and powder dispensing device

A device for dispensing a measured amount of a particulate material having a body comprising a shaft and a crossbar connected by a three-way junction wherein the body is at least partially optically transparent,

• wherein the shaft comprises a supply aperture, a supply funnel, and attachment means for reversibly connecting the body with an external device, wherein the supply funnel extends between the supply aperture and the three-way junction and is adapted for directing a flow of particulate material between the supply aperture and the three-way junction,
• wherein the crossbar comprises a measurement portion and a dispensing portion extending in opposite directions from the three-way junction,
• wherein the measurement portion comprises a reservoir adapted for receiving a measured amount of solid particulate material,
• wherein the dispensing portion comprises a dispensing aperture, a dispensing pipe and attachment means for reversibly connecting the body with an external device, and wherein the dispensing pipe extends between the dispensing aperture and the three-way junction and is adapted for directing a flow of particulate material between the reservoir and the dispensing aperture, and
• wherein the three-way junction has an opening to the shaft, an opening to the measurement portion and an opening to the dispensing portion, wherein the opening of the shaft and the opening of the measurement portion form a measurement edge, and wherein the diameter of the opening to the dispensing portion is at least as great as the diameter of the opening to the measurement portion.
