The lower half and the upper half of this tube 8 are folded in two; and the tube 8, which is located inside of the bag 1, is partially fusion-welded by heat to the inner surface of a lower half 6 of the plastic film 2 on the outer surface side. In the meantime the tube 8, which is located outside of the bag 1, is pressed by a holding piece 9 to maintain the doubly folded state. Therefore, when a packing object is packed in the bag 1, the bag 1 swells out; and the holding piece 9 presses firmly on the folded part of the tube 8. So the inner surfaces of the tube 8, which is located outside of the bag 1, stick together tightly; and the sealing efficiency of the bag 1 is improved.

IPC: B41J2/045
Filed: 1989-12-21
Abstract: PURPOSE:To generate efficient pressure change in a liquid chamber by providing a piezoelectric element to a cover plate member itself. CONSTITUTION:Since the cover plate member (base block) 1 itself constituting a liquid chamber 15 is equipped with a piezoelectric element 7, the displacement of the piezoelectric element 7 is directly transmitted to the liquid chamber 15.
