PURPOSE: To obtain a vacuum packing method for reducing the volume of a container containing pulverized articles and making its transportation easy by providing at a sucking part in the container the material permeable to gas but impermeable to low-density powdery or pulverized articles to draw gas out of the container.

CONSTITUTION: The low-density pulverized chips 2 to be packed are weighed and the chips of 5kg are placed in an envelope-like polyethylene bag 1. After placement, the bag is shaked up and down to make the upper surface of the chips flat in an ordinary bagging manner. A plate-like slab 3 made of an air- permeable soft urethane is placed at the central part of the flat upper surface of the chips and gas is drawn out of the bag by a vacuum cleaner. At this time, the suction opening of a vacuum cleaner is held into contact with the soft urethane slab in its center, the place in contact with the slab is held with the hand in such a manner as to cover the suction opening of the vacuum cleaner with the polyethylene bag and then a switch of the vacuum cleaner is turned on. This sucking operation is continued for about 25 seconds until the polyethylene bag stops its shrinking and the opening of the bag is then tied with a string. In this way the volume of the bag can be reduced to at most half.
