Abstract

PURPOSE:To enable a simple container into which contents is filled to be formed into an approximately square pole shape by providing fixing point parts for fixing a front side part and a back side part on specified parts. CONSTITUTION:When contents is filled into a container main body A1, a front side part 100 and a back side part 101 of the container main body A1 are laterally extended, and both side seal parts 3 are inwardly drawn from right and left sides, thereby a flat square bottom part is formed on a W-shaped bottom part 2. The parts from fixing point parts 12 to both side seal parts 3 are inwardly dented. At this time, since the distance between the fixing point parts 12 and a boundary 14 on the lower level of a mouth part 1 is one-half as long as a folding width of the W-shaped bottom part 2, the height of the dent part not yet dented is approximately equal to the folding width of the W-shaped bottom part 2. Accordingly, a container main body A1 having an approximately square pole shape is formed, and the housing space can be decreased by forming this container main body A1 into the approximately same outside shape, moreover the value of merchandise can be improved.

The left and right W-bottom seal portions 9 are formed by obliquely sealing up to the inner edge 8), and usually have a bilaterally symmetrical plane shape. Thus, the contents are filled in the container body A that is normally folded in a planar shape. Then, since the container body A is made of a flexible material, the planar container body A has a three-dimensional shape. That is, the front side portion 100 and the back side portion 101 of the container body A swell back and forth with respect to the drawing sheet, and the left and right side seal portions 3 are drawn left and right with respect to the drawing sheet, thereby forming a planar container body.
