<p><P>PROBLEM TO BE SOLVED: To provide a composite container consisting of a flexible packaging bag and a sleeve material mounted on the outer periphery, capable of being held under an open condition, capable of providing self-standing property, and suppressing an increase in cost. <P>SOLUTION: In the composite container formed by approximately closely bonding and mounting the sleeve material on the outer face of the flexible packaging bag, pressed portions are respectively provided at corresponding positions of side parts of both sides of the sleeve material, and opening is performed by pushing the pressed portions inward, and the open condition is held to provide the self-standing property. The pressed portions have a shape in that opposing sleeve folding lines being the sides of both sides of the sleeve material are made to be axes of symmetry and pressed external folding lines are respectively provided on both sides in V shapes or approximately circular arc shapes, and the inside parts formed by the pressed external folding lines are made to be the pressed portions. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
