DUST CONTAINER

PROBLEM TO BE SOLVED: To provide a dust container constructed so as to efficiently contain a greater amount of elastic and bulking-natured dust although it is of a simple structructure. SOLUTION: This dust container 1 used for containing dust R is equipped with a container body 5 having a dust containing part 2 and a dust inlet port 3a formed in an upper surface 3 of the containing part 2. The container body 5 has the shape of a truncated cone formed by gradually enlarging inner cross section area of the containing part 2 from the inlet port 3a toward a lower surface 6. Based on what is called a tapered shape of the containing part 2 which becomes narrower toward the inlet port 3a, the dust R to be contained can be effectively inhibited from swelling. If the container body 5 is equipped with a protrusive part 11 on its inner circumferential surface 2a, the swelling of the contained dust R is more effectively regulated by the protrusive part 11, making it possible to contain much more dust R.
