PROBLEM TO BE SOLVED: To provide a method and a device for efficiently squeezing an opening of a bag without using a heat source, a bonding agent or the like. SOLUTION: A bag 1 storing a content 3 of given quantity is put into a cylindrical body 4 in the state of mounting a rotating ring 7 almost of same diameter as that of the cylindrical body 4 on the upper end of the cylindrical body 4 with upper and lower ends open, and the peripheral edge of an opening 2 of the bag 1 is set in the state of being folded back to the outside of the rotating ring 7, and the rotating ring 7 is attracted by a magnet 8 to clamp the peripheral edge of the opening 2 of the bag 1 by the magnet 8 and rotating ring 7, and the magnet 8 is rotated to squeeze the opening 2 of the bag 1 in the constitution of a bag squeezing method and a device therefor. |
