To provide an efficient box for holding refill liquid-containing bags.

The peripheral edges of the front and rear synthetic resin films are sealed and a projected pouring part 4 is formed at the peripheral side. A rigid or a half-rigid pipe is buried between the front and rear synthetic resin films, in the pouring part 4. Refill liquid-containing bags 1 provided with a hole at the bottom seal part are held in a box. A rod 13 in which the hole of bag is inserted is erected at the bottom of the box 12. Into the hole at the bottom seal part of the bag 1, the rod 13 is inserted, and the bags are arranged so that the projected pouring parts 4 of the bags 1 are not superposed with each other.
