A sack (2, 2 min ) comprises a sealing member (1, 1 min ) which is provided at an appropriate position of the sack (2, 2 min ), and a dried adhesive agent is spread on the inner walls of the sealing member (1, 1 min ). A supply pipe (3) comprises a curved head from which a nozzle (21) projects. The supply pipe (3) is inserted to supply powder materials into the sack (2, 2 min ), via an aperture of the sealing member (1, 1 min ), and then, after supply, the pipe (3) comes within the inner walls of the sealing member (1, 1 min ) where an activator is jetted from the nozzle (21). Sealing of the sack (2, 2 min ) is performed during it falls from a supporting member (30), owing to the outward pressure of the powder materials supplied in the sack (2, 2 min ). |
