[0031] figure 1 is a perspective view showing the first embodiment of the flexible container of the present invention, figure 2 Yes figure 1 Bottom view of the embodiment shown. As shown in these figures, the flexible container 1 according to the present embodiment has: a cylindrical side wall 12 fully open at the top, with a filling port 10b opening upward toward the drawing; In the direction perpendicular to the opening direction of the side wall 12; In this embodiment, since the filling port 10b is also used as a discharge port, the filling port 10b is referred to as "filling / discharging port 10b" here (the same applies to Figure 7 the fourth embodiment shown).

[0032] The side wall 12 is a cylindrical body made of a soft material, and a soft cylindrical cap member 10a having substantially the same outer peripheral length is provided at the filling / discharging port 10b. The cylindrical body 12 may be seamless, or may be formed into a cylindrical shape by winding a p...

[0045] image 3 is a perspective view showing a second embodiment of the flexible container of the present invention, Figure 4 Yes image 3 The side view of the embodiment shown, Figure 5 Yes image 3 Top and bottom views of the illustrated embodiment. As shown in these figures, the substantially rectangular parallelepiped main body 10 in the flexible container 2 of the second embodiment is mainly composed of the following parts: a side wall 12; side) and has a filling port 20 in its central area; and a bottom surface 15 formed on the other end side in the opening direction (lower side in the drawing) and has a discharge port 26 in its central area. The bottom surface 15 has the same shape and the same dimensions as those of the first embodiment. In addition, the structure other than these respective parts is basically the same as that of the first embodiment.

[0046] like Figure 3 to Figure 5 As shown, the top surface 11 is formed in a substantially quadrilateral p...

[0051] Image 6 It is a perspective view which shows 3rd Embodiment of the flexible container of this invention. In the third embodiment, the adjacent corners of the side wall 12 correspond to the adjacent first reinforcing belt parts 13, 13 among the corresponding belt parts 12a, 12a, and second reinforcing belt parts 30, 30, .. ., this point is different from the second embodiment, and the structure is basically the same as that of the second embodiment.

[0052] In the middle of the first reinforcing strip parts 13, 13 respectively provided on the adjacent corner corresponding strip parts 12a, 12a, each second reinforcing strip part 30 is arranged so as to divide a part of the side wall 12 between them. into two equal parts. The shape and reinforcement form of each second reinforcing belt portion 30 are the same as those of the first reinforcing belt portion 13 and are not particularly limited. For example, in the case of the aforementioned yarn textures, it can be reinf...

Abstract

The invention provides a flexible container that is capable of being stably stacked, as well as suppressing body bulging after packing and increasing packing efficiency while reducing changes in packing shape. This flexible container (1) is characterized by comprising a body portion, said body portion having a tubular side wall (12), a packing port (10b) that is formed on one end side of the sidewall (12) in the opening direction thereof, a substantially polygonal bottom surface (15) that is provided to the other end side in a direction orthogonal to the opening direction, and suspension beltsupport portions (17) that are provided to at least two opposite locations on the side wall (12), wherein: the planar shape of the bottom surface (15) is a polygon with (2n+2) sides (where n is an integer from 1 to 5), the corners of which are each rounded; on the side wall (12), first reinforcement band portions (13) that have a band shape reaching both ends of the side wall (12) parallel to theopening direction thereof are provided to a plurality of locations at predetermined intervals in the peripheral direction of the side wall (12); and the suspension belt support portions (17) are provided to the surfaces of the first reinforcement band portions (13). Furthermore, a second reinforcement band portion (30) for partitioning a space between adjacent first reinforcement band portions (13) into a plurality of equal areas can be provided between said adjacent first reinforcement band portions (13).

Description

technical field [0001] The invention relates to a flexible container used for transportation and storage of powder and granular bodies. Background technique [0002] Currently, in many industries, flexible containers are used to transport and store various substances, such as resin particles, chemical products, powders and liquids of inorganic substances, minerals, grains, feed, etc., regardless of their types and shapes. Basically, a flexible container mainly has the following structures, namely: a cylindrical main body having a circular or quadrangular cross-sectional shape; top and bottom surfaces sewn to upper and lower edges of the main body, respectively; and suspension straps mounted on the main body. A sealable input portion is provided in the central area of ​​the top surface, and a sealable discharge portion is provided in the central area of ​​the bottom surface as required. [0003] According to its usage method, flexible containers are classified into running-...
