Powder container with a nozzle receiver
A powder container includes a nozzle receiving opening, a container body, a nozzle receiver including the nozzle receiving opening; a gear, and two scoops. Further, there is a shutter to open and close the nozzle receiving opening, a spring to bias the shutter, two protrusions which protrude away from the nozzle receiving opening. The scoops extend in the longitudinal direction along a first length, the protrusions extend in the longitudinal direction along a second length, and a position of the first length and a position of the second length at least partly overlap along the longitudinal direction. The powder dropped from the higher position enters the region by passing between the protrusions when the scoops are rotated about the rotational axis, and the protrusions are rotated, due to the rotation of the gear, around the region when the scoops are rotated about the rotational axis.
