Powder holding container with an opening and closing member having a resilient tab surrounded by a cutout

摘要

A powder holding container includes: a tubular shaped section that is formed in a tubular shape with a hole formed in a tube wall for letting powder pass through; an opening and closing member that moves in a straight line inside the tubular shaped section to open and close the hole; a projection portion that projects out from the opening and closing member and enters the hole; and a resilient tab that is formed by a cutout provided in the opening and closing member, and is resiliently deformable in directions in which the projection portion enters or exits the hole.
