The net-like material is formed by knitting fibers vertically and horizontally. The thickness of the fibers constituting the net-like material is preferably 800 to 1000 dtex, and more preferably 890 dtex. It is preferable that the longitudinal fibers have higher rigidity than the lateral fibers by knitting a plurality of fibers. Moreover, it is preferable to use the recycled fiber, for example, from the viewpoint of strength and environmental protection.

  FIGS. 2A to 2C are a sectional view taken along line IIa-IIa, a sectional view taken along line IIb-IIb, and a sectional view taken along line IIc-IIc in FIG.

  The side part 3 is comprised from the net-like material of 1 sheet. As shown in FIG. 1A, the side surface portion 3 has three first overlapping portions 31 and one second overlapping portion 32. As shown in FIGS. 1 (a) and 2 (a), the first overlapping portion 31 is formed by partially overlapping the net-like material constituting the side surface portion 3 in the circumferential direction, and the base of the overlapped portion. It is formed by stitching the end portion in the vertical direction (stitch line S1). As shown in FIG. 1A and FIG. 2B, the second overlapping portion 32 bends one circumferential end portion of the net-like material constituting the side surface portion 3 to form the other circumferential end portion. It is formed by sandwiching and suturing in the vertical direction (suture line S2). These three first overlapping portions 31 and one second overlapping portion 32 form the four vertical ridge line portions 4 of the rectangular columnar container 1A.

  As shown in FIGS. 1A and 2C, the lower portion of the side surface portion 3 and the lower surface portion 2 include three first overlapping portions 31 and one second overlapping portion 32 of the lower surface portion 2. After being arranged in the vicinity of the four corners, the lower portion of the side surface portion 3 and the four sides of the lower surface portion 2 are overlapped and stitched in the circumferential direction (sewn line S3). The lower portions of the three first overlapping portions 31 and the lower portion of one second overlapping portion 32 are folded so as to be in contact with the side surface portion 3 and are sewn together with the side surface portion 3 and the lower surface portion 2.
