<P>PROBLEM TO BE SOLVED: To provide a box-shaped container with a refill bag accommodated therein being made of film, thereby improving the easiness to open the bag. <P>SOLUTION: The box-shaped container includes: a bag 10A made of a film with powder-like substance filling the same; a box-shaped container body 30 with the bag 10A accommodated in the same; a lid 40 for covering the opening of the box-shaped container body 30. The bag 10A has a gusset at the bottom or on the side thereof with its top portion in a flat bag shape, and the internal dimension of the bag is narrower at the bottom than at the top portion, making itself into an inverted tapered shape.
