WIPO Patent Application WO/2008/032402
Kind Code:
A1
Abstract:
A stand pouch exhibiting free-standing properties when it is filled with a fluid
matter and not yet unsealed and free-standing properties in a three-dimensional
shape even after the entire quantity of fluid matter has flowed out, in which a
constricted outlet is not closed when the fluid matter is made to flow out, and
the front and rear surface portions can be prevented from approaching and shrinking.
A bag package is filled with a fluid matter by opening the upper end opening edge
of the stand pouch before its upper end opening is closed, and delivers the fluid
matter by cutting the closed upper end opening. The upper end opening of the stand
pouch is flattened to become a constricted cross opening when viewed from above,
then two flat portions on the sides of the bag are superimposed on the flat portion
on the rear surface side of the bag, the flat portion on the front surface side of
the bag and three flat portions are made planar on the side face side of the bag and
the upper ends of all flat portions are subjected to top heat sealing. The three
flat portions are kept superimposed by top heat sealing, and the flat portion
on the front surface side of the bag is cut open to provide an outlet for making the
fluid matter flow out.
