PROBLEM TO BE SOLVED: To shape a good block-shaped package at the same time as manufacturing without causing a swell due to pressure reduction inside a bag. SOLUTION: A periphery of a contents filled site 5a of a bag 5 is pressed by a press board 9, while an upper part is pressed by a fixed rod 7 to push up a bottom of the bag 5 by a push-up plate 10. The bag 5 is vertically pressed by the fixed rod 7 and the push-up plate 10, the inside of the bag 5 is reduced in pressure by a nozzle 6 in the pressed state, and thereafter the bag is sealed. A good block shape can be obtained without the bag 5 pulled upward by the pressure reduction. |
