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