Description

  The present invention relates to a flexible container bag. In detail, it is related with the flexible container bag for improving the efficiency of accommodation work. Here, the flexible container bag includes a large sandbag.

  Conventionally, when storing and transporting soil, granular materials, and other objects to be stored, it can be folded when not in use, and when used (when storing objects to be stored), the capacity is increased and a large amount is stored. A flexible container bag, which is a bag body that can store objects, has been used. (See Patent Document 1)

  FIG. 15 shows an example of a conventional flexible container bag (F11). FIG. 15A shows an example of a circular cylinder (with bottom), and FIG. 15B shows an example of a square cylinder (with bottom) (F12). In FIG. 15 (a), the flexible container bag (F11) is connected to the lower part of the bag body (consisting of the body part 1A and the bottom part 3A) and the lower part of the bag body (1A and 3A). The upper part of the bag body (cylindrical lid part 2A) that covers the lower part of the bag body (1A, 3A) after storing the object, and the suspension belts (4A, 7A, 8A) and a reinforcing member (6A) provided at appropriate positions on the lower portion of the bag (1A and 3A) to reinforce the lower portion of the bag (1A and 3A).

  These lower bag body (1A and 3A), upper bag body (2A), suspension belt (4A, 7A, 8A) and reinforcing material (6A) are formed of sheets. FIG. 15A shows a state in which the flexible container bag (F11) is spread and placed so that the lower bag body (1A and 3A) is on the lower side and the upper bag body (2A) is on the upper side. It shows an empty state with no containment. The upper part (2A) of the bag body is a port for loading and unloading objects. Also, two suspension belts (4A, 7A, 8A) are attached near the boundary between the lower bag body (1A and 3A) and the upper bag body (2A). In the suspension belt, the suspension hand (4A), the portion (7A) attached to the trunk portion, and the portion (8A) attached to the bottom portion are integrally connected.

  The flexible container bag (F11) is used as a sandbag, for example, containing soil. Moreover, it can accommodate and carry cereals and other various items. Flexible and foldable. The suspension belts (4A, 7A, 8A) are used for lifting and moving with a forklift or a crane.

In FIG. 15 (b), the flexible container bag (F12) is connected to the lower part of the bag body (consisting of the body part 1B and the bottom part 3B) that accommodates the object to be accommodated and the lower part of the bag body (1B and 3B). An upper part of the bag body (cylindrical lid part 2B) that covers the lower part of the bag body (1B, 3B) after storing the object, and a suspension belt ( 17B ) for lifting the bag body (upper part of the bag body and lower part of the bag body), A reinforcing member (18B) is provided at an appropriate position on the lower portion of the bag body (1B and 3B) to reinforce the lower portion of the bag body (1B and 3B), and a reinforcing belt (8B). Differences from FIG. 15A will be mainly described.

In FIG. 15 (a), the upper part of the bag and the lower part of the bag were circular cylinders (with bottoms) and the bottom (3A) was circular, but in FIG. 15 (b), the upper part of the bags and the lower part of the bag were square. It is cylindrical (with bottom) and the bottom (3B) is square. In FIG. 15A, the two suspension hands (4A) of the suspension belt extend from the vicinity of the boundary. In FIG. 15B, the four suspension belts (17B) form the four corners of the square that form the boundary. It is attached in the very vicinity. 15 (a), the suspension belts (7A, 8A) are used to reinforce the body (1A) and the bottom (3A), but in FIG. 15 (b), the reinforcement belt (8B) is the body. Used for reinforcement of (1A), the bottom (3B) is not reinforced. In FIG. 15A, the reinforcing material (6A) is provided outside the trunk (1A) in order to reinforce the connection between the suspension hand (4A) and the trunk (1A). In FIG. 15 (b), a reinforcing material (18B) is provided outside the body (1B) in order to reinforce the connection between the suspension belt (17B) and the body (1B), and the reinforcing belt (8B) is provided on the body. In order to reinforce a part (1B), it is provided along the ridgeline of a trunk | drum (1B). Other configurations are the same as those in FIG.

  FIG. 16 shows a state after the objects to be stored in the flexible container bags (F11, F12) are stored. FIG. 16A shows an example in which the flexible container bag (F11) has a circular cylindrical shape, and FIG. 16B shows an example in which the flexible container bag (F12) has a rectangular cylindrical shape. The upper part (2A, 2B) of the bag body is squeezed inward, and its mouth is tied and tied with a string (11A, 11B). As a result, the mouths of the bag bodies (upper bag body and lower bag body) are closed and can be transported.

  Since such flexible container bags (F11, F12) are flexible, there is a drawback that manpower is required to keep the mouth open and open when storing the contents.

  FIG. 17 shows another example of a conventional flexible container bag (F13) (an example of a circular cylinder (with a bottom)). Compared to the above example, the hook (19A) is attached outside the lower bag body (1B and 3B) and near the boundary with the upper bag body (2B). FIG. 17A shows a state where the flexible container bag (F13) is empty, and FIG. 17B shows a state where the hook (19A) is used. In this example, as shown in FIG. 17 (b), the suspension strap 9A is hung on the hook 19B and pulled from above (or from an obliquely upward outer side). By doing in this way, even if it does not depend on a hand, the mouth of a bag body can be expanded and it can be maintained in the upright state, and a to-be-contained object can be accommodated.

Japanese Patent Laid-Open No. 11-180488 (paragraphs 0017 to 0041, FIGS. 1 to 5)

  However, in such a conventional flexible container bag, the upper portion of the bag body (cylindrical lid portions 2A and 2B) enters into the inside when stored, making it difficult to put an object to be stored when stored, and the upper portion of the bag body. There was a problem that the (cylindrical lid portions 2A and 2B) were buried in the objects to be contained and it was difficult to pull them out. Therefore, as a solution, there has been a problem that workability is impaired because work such as manually rounding the upper part (2A, 2B) of the bag body manually is required.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a flexible container bag that improves the efficiency of accommodation work by adopting a configuration in which the upper portion of the bag body is bent during storage and does not enter the inside of the lower portion of the bag body.

  In order to solve the above problems, the flexible container bag (F1, F2) according to the first aspect of the present invention is formed of a sheet as shown in FIG. The body 1A, 1B and the bottom 3A, 3B) and a sheet, and connected to the bag lower part (1A, 1B and 3A, 3B) to accommodate the object to be stored, the bag lower part (1A, 1B and 3A, 3B) and a hook (5A, 5B) provided inside the bag upper part (2A, 2B).

  Here, the “sheet” is typically a woven fabric made of polypropylene and woven vertically and horizontally using wide yarn. Synthetic resin threads and hemp threads other than polypropylene may be used. The tensile strength is increased by using a woven fabric. Moreover, since the sheet is flexible, the flexible container bag can be folded, and can be folded and stacked when not in use. Since the lower part of the bag body is loaded with the load to be contained, a thick sheet is used and it is difficult to bend. On the other hand, the upper part of the bag body uses a thin sheet to narrow the tip and use it as a lid for the bag body. It's getting softer. Further, the “flexible container bag” is a bag for storing and storing or transporting an object to be stored. Here, the flexible container bag mainly includes a large sandbag for storing soil, sand, and the like. The “inner side” refers to the side of the bag body (the upper part of the bag body and the lower part of the bag body) that accommodates objects, and the “outer side” refers to the opposite side. Further, the “hook” is provided in the bag body in order to keep the mouth of the bag body (the upper part of the bag body and the lower part of the bag body) in an open state by hooking and pulling a hanging string. Typically circular. The length is usually several centimeters, but it may be longer or shorter. Moreover, even if it has a ring shape and has a ring at the tip, it may be used without a ring and tied at the tip. When it is formed in a ring shape or has a ring at the tip, workability at the time of lifting with a hanging strap or the like is good.

  The “hook provided inside the upper part of the bag body” is attached to the inner side of the lower part of the bag body, and is attached to the outer side of the lower part of the bag body. An annular hook extending toward the upper portion of the bag body and entering inside through a slit provided in the upper portion of the bag body is included. The hook is attached to the inner side of the lower part of the bag body, extends toward the upper part of the bag body, fits inside the upper part of the bag body, and further extends from the mouth of the upper part of the bag body (a ring is formed at the tip). Attached to the outside of the lower part of the bag body, extends toward the upper part of the bag body, enters the inside of the upper part of the bag body through a slit provided in the upper part of the bag body, and further upper part of the bag body Also included are cords that extend outward from the mouth (including cords with a ring formed at the tip and cords that are not formed).

  The hooks (5A, 5B) are preferably attached to the inside of the lower bag body (1A, 1B and 3A, 3B) and near the boundary with the upper bag body (2A, 2B). “Near the boundary” is not limited to the position on or in contact with the boundary, and the lower part of the bag body stands substantially upright when a hanging strap (usually having a hook at the tip) is pulled on the hook. It shall be included “near the boundary” unless the upper part is bent into the lower part of the bag body. Note that the term “substantially upright” does not have to be properly upright, and may be upright to such an extent that it can be accommodated.

  Any material can be used as long as it can be accommodated in a sheet-like bag. For example, it may be a solid waste such as grains, wheat flour, sand, dirt such as earth, chips, waste, or food. In addition, when the sheet is made of woven fabric, it is air permeable and is suitable for storing grains and the like. When it is desired to seal it, it is used after surface coating. There are also a running type (reusable) and a cross type (disposable).

  If comprised like this aspect, it will be provided with the hook (5A, 5B) attached near the boundary with a bag upper part (2A, 2B) inside a bag lower part (1A, 1B and 3A, 3B), and it will be cyclic | annular. By hooking the hook (5A, 5B) with a hanging string or the like and pulling it from above, or by pulling the string-like hook (15A, 15B; see FIG. 7) itself from above, the upper part of the bag (cylindrical lid 2A, 2B) is less likely to be inside, and can be prevented from entering the body (1A, 1B). Further, the upper part of the bag body (cylindrical lid parts 2A, 2B) can be hung in a skirt shape outside the lower part of the bag body (1A, 1B and 3A, 3B), so that the housing operation is not hindered. Therefore, the flexible container bag which improves the efficiency of accommodation work can be provided.

  Further, in the flexible container bag (F3, F4) according to the second aspect of the present invention, in the first aspect, for example, as shown in FIG. 5, the hook is the lower part of the bag body (1A, 1B and 3A, 3B). The upper part of the bag body (2A, 2B) or the boundary between the lower part of the bag body (1A, 1B and 3A, 3B) and the upper part of the bag body (2A, 2B) is a slit. A slit that allows the hooks (12A, 12B) to be provided inside the upper bag body (2A, 2B) by inserting the hooks (12A, 12B) from the outer side to the inner side of the upper bag body (2A, 2B). (13A, 13B) is formed.

  Here, the slit may be in the vertical direction or the horizontal direction, and may have any shape as long as the hooks (12A, 12B) can be inserted. Further, “the vicinity of the boundary” is not limited to the position on or in contact with the boundary, but may be any position that is not more than the length of the ring of the hooks (12A, 12B) from the boundary. If comprised like this aspect, it will be equipped with the hook (12A, 12B) attached near the boundary with a bag upper part (2A, 2B) on the outer side of a bag lower part (1A, 1B and 3A, 3B), and a slit. Insert the tip of the hook (12A, 12B) from the outside (13A, 13B) to the inside from the outside of the upper bag body (2A, 2B), hang a hanging string etc. on the hook (12A, 12B), and pull from above The upper portion of the bag (cylindrical lid portions 2A, 2B) is less likely to be inside, and can be prevented from entering the inside of the trunk portion (1A, 1B). Therefore, the flexible container bag which improves the efficiency of accommodation work can be provided. Moreover, the slit (13A, 13B) can be opened and used for the existing flexible container bag which has a hook (19A: refer FIG. 17) on the outside. Further, since the hooks (12A, 12B) are attached to the relatively strong bag body lower portions (1A, 1B and 3A, 3B), the bag body is hardly damaged. The slits (13A, 13B) are not limited to the upper portion (2A, 2B) of the bag body, and may be provided near the boundary at the lower portion of the bag body. However, when it is provided on the upper part (2A, 2B) of the bag body made of a thin sheet, the workability in manufacturing is good.

  Further, in the flexible container bag (F5) according to the third aspect of the present invention, in the second aspect, for example, as shown in FIG. 6, a slit cover (13A) covering the upper part (2A) of the bag body (2A) 14A) is attached.

  Here, the slit cover (14A) may be attached to the outside of the bag body upper part (2A), or may be attached to the inside. The outside is easy to attach, and the contents are difficult to leak when attached to the inside. In addition, the hook is inserted into the U-shape that opens toward the mouth of the bag when attached inside, and the U-shape that opens toward the bottom of the bag when attached outside. It is suitable because it is easy and leakage can be reduced. If comprised like this aspect, since the slit cover (14A) is attached to the slit (13A), it is possible to prevent the material to be leaked from the slit (13A) to the outside of the bag body. In addition, when providing a slit cover (14A) inside a bag body, you may sew in the state opened toward the bottom. In this case, it is preferable that the upper end is sewn in a straight line and hung downward rather than in a U-shape. When the object is stored and the hook is pulled out, the slit cover (14A) hangs down naturally and closes the slit (13A).

  Further, in the flexible container bag (F21, F22) according to the fourth aspect of the present invention, in the first aspect, for example, as shown in FIG. 10, the hook is attached to the inside of the bag body upper part (2A, 2B). It has been. With this configuration, the hooks (25A, 25B) are always visible, so that the opening of the upper portion (2A, 2B) of the bag body can be easily held at the time of additional charging or removal of excessive charging, which is convenient. Further, during the operation of accommodating the objects to be accommodated, the portion below the hook attachment portion of the upper portion of the bag body (2A, 2B) is above the boundary line with the lower portion of the bag body (1A, 1B and 3A, 3B). Become almost upright. In this state, the part above the hook attaching part at the upper part of the bag body can be hung in a skirt shape outside the substantially upright bag upper part (2A, 2B). Therefore, the objects to be accommodated can be sufficiently packed in the lower portions of the bags (1A, 1B and 3A, 3B). That is, it can be accommodated more than the boundary line without spilling, and then it can be lifted with a suspension belt and shaken, or it can be gently dropped on the floor to vibrate up and down. It is possible to settle down to the position of the boundary line, that is, fully in the lower part of the bag body (1A, 1B and 3A, 3B).

  Moreover, the flexible container bag (F1) according to the fifth aspect of the present invention is the flexible container bag (F1) in any one of the first to fourth aspects as shown in FIG. 1 (a), for example. When placed with the lower body (1A and 3A) facing down and the upper bag body (2A) facing up, the lower bag body (1A and 3A) and the bag along the lower bag body (1A and 3A) The belt (7A) is arranged to extend downward from near the boundary with the upper body (2A), and the hook (5A) is attached to connect to the belt (7A) near the boundary.

  Here, if the hook is attached so as to be connected to the belt (hanging belt) near the boundary, the belt (4A, 7A, 8A) has a suspension hand (4A) extending upward from near the boundary. , Extending from the vicinity of the boundary to the suspension (4A) and extending downward, via the bottom (3A) at the bottom of the bag body, and extending upward from the vicinity of the boundary on the opposite side ( You may be comprised so that it may continue to 4A). Further, the belts (4A, 7A, 8A) have a tensile strength suitable for lifting the flexible container bag (F1) containing the objects to be stored. For example, in the case of a flexible container bag that accommodates 1 ton of objects, it can withstand lifting of 4 to 5 tons. The hook may be used as a suspension belt and may have a tensile strength used for lifting the flexible container bag. The hook may be provided separately from the suspension belt, and accommodates an object to be stored in the flexible container bag (F1). It may be used only for raising the bag body so as to stand upright during the work. If comprised like this aspect, since the hook (5A) continues in a straight line to the belt (7A, 8A), the durability of the hook (5A) increases.

  Moreover, the flexible container bag (F1) which concerns on the 6th aspect of this invention is a belt (4A, 7A, 8A) from the vicinity of a boundary in a 5th aspect, for example, as shown to Fig.1 (a). It has a suspension hand (4A) extending upward, and the suspension hand (4A) and a portion (7A, 8A) arranged so as to extend downward from near the boundary are integrally configured.

Here, since the suspension hand (4A) of the belt (suspending belt) and the portion (7A, 8A) arranged to extend downward are integrally formed, the hook (5A) is the suspension belt (4A). Is connected to the inside (may be the inside of the body 1A). When the hook (5A) is attached to the outside of the body portion 1A, a slit (13A) is formed in the bag body upper portion (2A).
If comprised like this aspect, since a belt (4A, 7A, 8A) is comprised integrally, the durability of a suspension hand (4A) will increase.

  Moreover, the flexible container bag which concerns on the 7th aspect of this invention is a bag lower part (1A, 1B and 3A, 3B) and a bag in any one of the 1st thru | or 6th aspect, for example, as shown in FIG. The upper body (2A, 2B) is formed in a substantially circular cylindrical shape or a substantially rectangular cylindrical shape.

  Here, “substantially” of a substantially circular cylindrical shape or a substantially rectangular cylindrical shape means that the circular shape is slightly collapsed into an elliptical shape, the rectangular shape is slightly collapsed and rounded, the surface is chamfered, or the corners are smooth. This indicates that some changes, such as, may be added. Moreover, in this aspect, one of the cylinders is opened and the other is the bottom (3A, 3B). When configured as in this embodiment, the bag body lower part (1A, 1B and 3A, 3B) and the bag body upper part (2A, 2B) are formed in a substantially circular cylindrical shape or a substantially rectangular cylindrical shape. Moreover, the volume of the bag body per sheet area can be increased.

  ADVANTAGE OF THE INVENTION According to this invention, the flexible container bag which improves the efficiency of accommodation work can be provided by making it the structure which an upper part of a bag body bends at the time of accommodation, and does not enter inside a lower part of a bag body.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted.

  Embodiment 1 will be described with reference to FIGS. In the first embodiment, annular hooks (5A, 5B) are attached to the inner side of the lower part of the bag body (body parts 1A, 1B and bottom parts 3A, 3B) and near the boundary with the upper part of the bag body (2A, 2B). An example will be described.

  FIG. 1 shows an example (empty state) of flexible container bags (F1, F2) in the first embodiment. FIG. 1A shows an example in which the flexible container bag (F1) has a circular cylindrical shape (with bottom), and FIG. 1B shows an example in which the flexible container bag (F2) has a rectangular cylindrical shape (with bottom). Indicates. In FIG. 1A, the flexible container bag (F1) is connected to the lower part of the bag body (consisting of the body part 1A and the bottom part 3A) and the lower part of the bag body (1A and 3A). The upper part of the bag body (cylindrical lid part 2A) that covers the lower part of the bag body (1A, 3A) after storing the object, and the suspension belts (4A, 7A, 8A), inside the bag lower part (1A and 3A), in the vicinity of the boundary between the bag upper part (2A) and the annular hook (5A) and the bag lower part (1A and 3A). And a reinforcing material (6A) for reinforcing the lower portion of the bag body (1A and 3A).

  These lower part of the bag body (body part 1A and bottom part 3A), upper part of the bag body (cylindrical lid part 2A), suspension belt (4A, 7A, 8A), annular hook (5A) and reinforcing material (6A) are formed of sheets. Is done. A “sheet” is typically a woven fabric made of polypropylene and woven vertically and horizontally using wide yarn. Synthetic resin threads and hemp threads other than polypropylene may be used. The tensile strength is increased by using a woven fabric. Moreover, since the sheet is flexible, the flexible container bag can be folded, and can be folded and stacked when not in use. FIG. 1A shows a state in which the flexible container bag is spread and placed so that the lower bag body (1A and 3A) is on the lower side and the upper bag body (2A) is on the upper side. It shows no empty condition. Actually, since the flexible container bag (F1) is flexible, it does not stand upright if it is not supported, but here it shows an upright state (the same applies to other drawings). The upper part (2A) of the bag body is a port for loading and unloading objects. Also, two suspension belts (4A, 7A, 8A) are attached near the boundary between the lower bag body (1A and 3A) and the upper bag body (2A). In the suspension belt, the suspension hand (4A), the portion (7A) attached to the trunk portion, and the portion (8A) attached to the bottom portion are integrally connected. The suspension hand (4A) is used to lift and move by a forklift or a crane. Further, the appropriate place is typically a position where a tensile force is applied when the hand (4A) is lifted by a crane or the like. The vicinity of the boundary is not limited to the position on or in contact with the boundary, and when the suspension strap is attached to the position and the suspension strap is hooked and pulled, the lower portion of the bag body is substantially upright, and the upper portion of the bag body is It is supposed to include a region that does not enter the inside of the lower part of the bag.

  The flexible container bag (F1) is used as a sandbag, for example, containing soil. Here, the flexible container bag mainly includes a large sandbag for storing soil, sand, and the like. In addition, it can accommodate and transport flour, rice grains, swarf, waste and other various items. Any material can be used as long as it can be accommodated in a sheet-like bag. By using a sheet as a woven fabric, the tensile strength is increased and a heavy material can be accommodated. Although the sizes are various, for example, a flexible container bag (F1) having a diameter of 1.1 m and a height of 1.1 m at the lower part of the bag body (1A and 3A) can accommodate and carry 1 ton.

  The upper part of the bag body (2A) used as a lid and the annular hook (5A) for hanging the hanging strap for holding the upper part of the bag body in an open state are applied with a relatively thin and soft sheet (than the lower part of the bag body). A relatively thick and hard sheet (than the upper part of the bag) is used for the lower part of the bag (1A and 3A), the suspension belts (4A, 7A, 8A) and the reinforcing material (6A). A relatively thick sheet may be used for the annular hook (5A). The annular hook (5A) only needs to be strong enough to pull up the trunk (1A) at the bottom of the bag body by pulling upward at least upward. In addition, substantially upright means that it is sufficient to stand upright to such an extent that it does not interfere with the accommodation work.

  When the flexible container bag is placed with the lower part of the bag (1A and 3A) facing down and the upper part of the bag (2A) facing up, the suspension belt (4A, 7A, 8A) is placed outside the trunk (1A) The two suspensions (4A) are attached so as to face each other and extend upward from near the boundary between the lower bag body (1A and 3A) and the upper bag body (2A). 4A) and a portion (7A) that reinforces the trunk from the vicinity of the boundary is arranged so as to extend downward along the trunk (1A), and further a portion (8A) that reinforces the bottom. A trunk portion arranged to extend from the center of the bottom portion (3A) along the bottom portion (3A) so as to be continuous from the belt (7A) and to be continuous from the other suspension belt (4A). It continues to the part (7A) to be reinforced. Further, from the vicinity of the boundary, the hook (5A) is attached to the inside of the trunk portion (1A) so as to be continuous with the portion (7A) for reinforcing the trunk portion. The reinforcing member (6A) is attached to the outer side and the inner side of the trunk (1A) in order to reinforce the connection between the suspension belt suspender (4A) and the hook (5A) and the trunk (1A). Yes.

  Upper bag body (2A), lower bag body (1A and 3A), lower bag body (1A and 3A), suspension belt (4A, 7A, 8A), trunk (1A) and hook (5A), trunk (1A ) And the reinforcing material (6A) are sewn together with a thread (for example, a sewing thread).

  Since the bag body lower part (1A and 3A) uses a relatively thick sheet and is reinforced by a part of the suspension belt (7A), it can be held substantially upright by lifting and holding the hook (5A). On the other hand, since a relatively thin sheet is used for the upper part of the bag (2A), it cannot be held substantially upright, and as it is, it enters the inside of the trunk (1A).

  In FIG. 1 (b), the flexible container bag (F2) is connected to the lower part of the bag body (consisting of the body part 1B and the bottom part 3B) and the lower part of the bag body (1B and 3B). An upper part of the bag body (cylindrical lid part 2B) that covers the lower part of the bag body (1B, 3B) after storing the object, a suspension belt (4B) for lifting the bag body (upper part of the bag body and lower part of the bag body), An annular hook (5B) attached near the boundary with the upper bag body (2B) inside the lower bag body (1B and 3B) and provided at appropriate positions on the lower bag body (1B and 3B). A reinforcing belt (8B) for reinforcing the tensile strength of (1B and 3B) and a reinforcing material (6B, 7B) are provided. Differences from FIG. 1A will be mainly described.

  In FIG. 1 (a), the upper part of the bag body and the lower part of the bag body have a circular cylindrical shape (with a bottom), and the bottom part (3A) has a circular shape. However, in FIG. It is cylindrical (with bottom) and the bottom (3B) is square. In FIG. 1A, the suspension belt hangers (4A) and hooks (5A) are attached to the same part of the boundary, but in FIG. 1B, they are attached to different parts. That is, the hook (5B) is attached to the four corners of the square that constitutes the boundary, and the reinforcing belt (8B) is arranged along the ridge line of the rectangular parallelepiped of the body (1B) so as to be continuous with the hook (5B). (4B) is attached at a position slightly away from the four corners of the square that the boundary constitutes. In FIG. 1 (a), the suspension belt (8A) is used to reinforce the bottom (3A), but in FIG. 1 (b), no belt is used to reinforce the bottom (3B). In FIG. 1 (a), the reinforcing material (6A) has an outer side and an inner side of the trunk (1A) in order to reinforce the connection between the suspension hand (4A) and the hook (5A) and the trunk (1A). In FIG. 1 (b), the reinforcing material (6B) is provided outside the trunk (1B) to reinforce the connection between the suspension belt (4B) and the trunk (1B). A reinforcing material (7B) is provided inside the body (1B) to reinforce the connection between the hook (5B) and the body (1B). Other configurations are the same as those in FIG.

  Therefore, the flexible container bag (F2) is foldable and can accommodate a heavy object, like the flexible container bag (F1). Various sizes are available. For example, a flexible container bag (F2) with a bottom area of 0.9m x 0.9m and a height of 1.2m at the bottom of the bag (1B and 3B) can hold and carry 1 ton. It is. In addition, a relatively thick sheet is used for the lower part (1B and 3B) of the bag body and is reinforced by the reinforcing belt (8B), and can be held substantially upright by pulling the hook (5B) upward. Compared to this, a relatively thin sheet is used for the upper part (2B) of the bag body, and it cannot be held substantially upright, and as it is, it enters the inside of the trunk part (1B). In addition, the configuration in which the suspension belt is located away from the four corners as described above can withstand the weight of the stored item even if the bottom of the bag body is longer than the width of the suspension belt. Suitable for cases. Of course, even when the bag body is a quadrangular cylinder, it is possible to attach the suspension belts to the four corners near the boundary. As shown in FIG. 15B, four suspension belts are attached to the four corners very close to the boundary. May be. The very vicinity means a state where the upper part (2B) of the bag and the lower part (1B and 3B) of the bag are in contact with the seams or slightly separated (for example, less than the width of the belt).

  FIG. 2 shows the usage state of the annular hooks (5A, 5B) of the flexible container bags (F1, F2) in the first embodiment. FIG. 2A shows an example in which the flexible container bag (F1) has a circular cylindrical shape (with bottom), and FIG. 2B shows an example in which the flexible container bag (F2) has a rectangular cylindrical shape (with bottom). FIG. 2 (c) shows a portion of the hook (9C) of the hanging strap (9A, 9B). In addition, although the hanging strap is drawn in a straight line shape, this indicates a state where it is pulled from above. The same applies to FIG. The suspension straps (9A, 9B) are hung on the hooks (5A, 5B) and pulled from above (or from the outside obliquely upward). Usually, a hook (9C) is provided at the tip of the hanging strap so as to be easily hooked on the hook (5A, 5B). It is safe if a stopper (9D) is provided on the hook (9C) so as not to come off the hook (5A, 5B). With this configuration, the upper portion of the bag body (cylindrical lid portions 2A, 2B) is difficult to be inside, and the bag body lower portions (1A, 1B and 3A, 3B) can be hung in a skirt shape. It is possible to prevent the inside of the part (1A, 1B).

  FIG. 2 (d) shows an example in which the flexible container bag (F1) has a circular cylindrical shape (with a bottom), and the hanging strap (9A) is hung and pulled from obliquely upward on the outside. In this case, by pulling diagonally from above, it is difficult for the upper portion (2A) of the bag to become inside, and it is possible to prevent the bag body (1A) from entering the inside. Moreover, since the bag body upper part (2A) can be hung down to the outer side of the bag body lower part (body | body part 1A) during the accommodation operation | work of the to-be-contained object, accommodation work can be performed smoothly.

  FIG. 3 shows another use state of the hooks (5A, 5B) of the flexible container bag (F1, F2) in the first embodiment. FIG. 3A shows an example in which the flexible container bag F1 has a circular cylindrical shape (with bottom), and FIG. 3B shows an example in which the flexible container bag F2 has a rectangular cylindrical shape (with bottom). The hanging hooks (10A, 10B) having no wrinkles are hung on the annular hooks (5A, 5B) and pulled from above (or from the obliquely upward outside). Even in this case, the upper portion of the bag body (cylindrical lid portions 2A, 2B) is less likely to be inside, and can be prevented from entering the body portions (1A, 1B).

  The state after accommodating the to-be-contained object of the flexible container bag (F1, F2) in Example 1 in FIG. 4 is shown. FIG. 4A shows an example in which the flexible container bag (F1) has a circular cylindrical shape (with bottom), and FIG. 4B shows an example in which the flexible container bag (F2) has a rectangular cylindrical shape (with bottom). . The upper part (2A, 2B) of the bag body is squeezed inward, and its mouth is tied and tied with a string (11A, 11B). As a result, the mouths of the bag bodies (upper bag body and lower bag body) are closed and can be transported.

  As described above, according to the present embodiment, it is possible to provide a flexible container bag that improves the efficiency of the housing operation by forming the upper portion of the bag body so as not to enter the inside of the lower portion of the bag body at the time of housing.

Example 2 will be described with reference to FIG. In the first embodiment, an example in which the annular hooks 5A and 5B are attached to the inside of the lower bag body (1A, 1B and 3A, 3B) and near the boundary with the upper bag body (2A, 2B) has been described. In Example 2, the annular hooks ( 12A , 12B ) are attached to the outside of the bag body lower part (1A, 1B and 3A, 3B) near the boundary with the bag body upper part (2A, 2B). In (2A, 2B), an example will be described in which slits (13A, 13B) are formed through which the tips of hooks ( 12A , 12B ) can be inserted from the outside to the inside of the bag body upper part (2A, 2B). Differences from the first embodiment will be mainly described (the following embodiments will also be described mainly with respect to differences from the previous embodiment).

  FIG. 5 shows an example (empty state) of the flexible container bag (F3, F4) in the second embodiment. FIG. 5A shows an example in which the flexible container bag (F3) has a circular cylindrical shape (with bottom), and FIG. 5B shows an example in which the flexible container bag (F4) has a rectangular cylindrical shape (with bottom). Indicates. Hooks (12A, 12B) are attached to the outside of the lower bag body (1A, 1B and 3A, 3B) and near the boundary with the upper bag body (2A, 2B), and the upper bag body (2A, 2B) A slit (13A, 13B) is formed through which the tip of the hook (12A12B) can be inserted from the outside to the inside of the bag upper portion (2A, 2B). Thereby, the front-end | tip of a hook (12A, 12B) can be inserted in the inner side of a trunk | drum. As shown in FIG. 2 or FIG. 3, the hooks (12A, 12B) are hung from the top of the hook and pulled upward, so that the upper part of the bag (cylindrical lids 2A, 2B) is less likely to be inside. It can hang down in the shape of a skirt outside the lower body (1A, 1B and 3A, 3B), and can be prevented from entering the body (1A, 1B). Further, after accommodating the objects to be accommodated, the hooks (12A, 12B) may be pulled out of the slits (13A, 13B) or may be left in the bag as they are. If it is pulled out, it is easy to prevent leakage, and if it has sufficient strength, the hook can also be used as a lifting hook (see FIG. 9). If you leave it, you can save time.

  The other configuration is the same as that of the first embodiment. Like the first embodiment, the upper portion of the bag body is bent during storage and does not enter the lower portion of the bag body, thereby improving the efficiency of the storage operation. Can provide.

  Embodiment 3 will be described with reference to FIG. In Example 3, an annular hook (12A, 12B) is attached to the outside of the bag body lower part (1A, 1B and 3A, 3B) near the boundary with the bag body upper part (2A, 2B). In (2A, 2B), the example in which the slits (13A, 13B) that can insert the tips of the hooks (12A, 12B) from the outside to the inside of the bag upper part (2A, 2B) is described. In Example 3, an example in which a slit cover (14A) that covers the slit (13A) is further attached to the upper portion (2A) of the bag body will be described.

  FIG. 6 shows an example (empty state) of the flexible container bag (F5) in the third embodiment. FIG. 6 shows an example in which the flexible container bag (F5) has a circular cylindrical shape (with a bottom). A slit cover (14A) is attached to the outside of the slit (13A). The slit cover (14A) covers the slit (13A) and prevents the object to be leaked from the slit (13A). In addition, even if the slit cover (14A) is not attached to the slit (13A), it will not leak to the outside as long as the object to be stored has a size that does not pass through the slit. it can. It is also possible to attach a slit cover (14A) inside the slit (13A). When installed inside, the effect of preventing leakage can be enhanced. When attaching the slit cover to the outside, the hook is sewn in a U-shape that opens toward the bottom of the bag, and when it is attached to the inside, it is sewn into a U-shape that opens toward the mouth of the bag. This is preferable because it can be easily inserted and leakage can be reduced. You may make it the shape opened toward the bottom also when attaching inside. In that case, it is better to use a cover with the upper part sewn in a straight line. In addition, even when the flexible container bag has a rectangular tube shape (with a bottom), the slit cover (14A) is similarly attached to the outside or the inside of the slit (13A).

  The other configuration is the same as that of the second embodiment. Like the second embodiment, the upper portion of the bag body does not enter the inside of the lower portion of the bag body when stored, and the flexible container bag improves the efficiency of the storing operation. Can provide.

  Embodiment 4 will be described with reference to FIG. In the first embodiment, an example in which an annular hook (5A, 5B) is attached to the inside of the bag body lower part (1A, 1B and 3A, 3B) and near the boundary with the bag body upper part (2A, 2B) will be described. However, in the fourth embodiment, an example in which the string-like hooks (15A, 15B) are attached will be described.

  FIG. 7 shows an example (empty state) of the flexible container bag (F6, F7) in the fourth embodiment. FIG. 7A shows an example in which the flexible container bag (F6) has a circular cylindrical shape (with bottom), and FIG. 7B shows an example in which the flexible container bag (F7) has a rectangular cylindrical shape (with bottom). Indicates. The string-like hooks (15A, 15B) are attached to the inside of the lower part of the bag body and near the boundary with the upper part of the bag body (2A, 2B), and extend in the direction of the upper part of the bag body (2A, 2B). A ring is formed at the tip of the top (2A, 2B). In this case, the ring extends outward from the mouth of the upper portion of the bag (2A, 2B), but passes through the inside of the upper portion of the bag (2A, 2B), so it is provided inside the upper portion of the bag (2A, 2B). There is no change in being a hook. The string-like hooks (15A, 15B) are pulled from the upper side (may be from the outside and obliquely upward). The ring is used for pulling with a hook or the like. Thereby, it becomes difficult for the upper portion of the bag (cylindrical lid portions 2A and 2B) to become inside, and can be prevented from entering the body portions (1A and 1B). Moreover, after accommodating a to-be-contained object, a hook (15A, 15B) can be left in a bag body with an accommodated object.

  The other configuration is the same as that of the first embodiment. Like the first embodiment, the upper portion of the bag body is bent during storage and does not enter the lower portion of the bag body, thereby improving the efficiency of the storage operation. Can provide.

  Embodiment 5 will be described with reference to FIG. In the first embodiment, an example in which an annular hook (5A, 5B) is attached to the inside of the bag body lower part (1A, 1B and 3A, 3B) and near the boundary with the bag body upper part (2A, 2B) will be described. However, in Example 5, a reversing belt (16A) for hanging the bag body upside down is attached to the bottom (3A, 3B) of the bag body lower portion (1A, 1B and 3A, 3B). An example will be described.

  FIG. 8 shows an example (empty state) of the flexible container bag (F8) in the fifth embodiment. FIG. 8 shows an example in which the flexible container bag (F8) has a circular cylindrical shape (with a bottom). A reversing belt (16A) for hanging the bag body upside down is attached to the bottom (3A, 3B) of the lower bag body (1A, 1B and 3A, 3B). When removing the contents, the crane is hung on the reversing belt (16A), the flexible container bag (F8) is turned upside down, the strap (11A) is unwound (see FIG. 4), the mouth of the bag is opened and the cover is opened. Drain the contents. Further, even when the flexible container bag has a quadrangular cylindrical shape (with a bottom), the reverse belt can be similarly attached.

  The other configuration is the same as that of the first embodiment. Like the first embodiment, the upper portion of the bag body is bent during storage and does not enter the lower portion of the bag body, thereby improving the efficiency of the storage operation. Can provide.

  Example 6 will be described with reference to FIG. In the first embodiment, an example in which an annular hook (5A, 5B) is attached to the inside of the bag body lower part (1A, 1B and 3A, 3B) and near the boundary with the bag body upper part (2A, 2B) will be described. However, in the sixth embodiment, an example in which a different type of suspension belt (17B) is attached instead of the suspension belt (4B) of the first embodiment (FIG. 1B) will be described.

  FIG. 9 shows an example in which the flexible container bag (F9) has a quadrangular cylindrical shape (with a bottom), and four suspension belts (17B) are provided very close to the four corners of the quadrangle that constitute the boundary. FIG. 9A shows an example in which the flexible container bag (F9) has a quadrangular cylindrical shape. An annular hook (5B) is attached to the inside of the bag lower part (1B and 3B) and very close to the boundary with the bag upper part (2B), and a suspension belt (17B) is attached to the outer side. The annular hook (5B) and the suspension belt (17B) are attached very close to the four corners of the square that the boundary constitutes. The suspension belt (17B) is used for lifting with a crane. Further, by hanging a hanging strap on the tip of the annular hook (5B) and pulling it upward as shown in FIG. 2 or FIG. 3, it becomes difficult for the upper portion of the bag body (2B) to become inside, and inside the trunk (1B). It can be prevented from entering.

  With reference to the partial extraction diagrams of FIGS. 9B and 9C, a modification of FIG. 9A will be described. Here, the suspension belt (17B, 17B ′) is attached outside the lower bag body (1B and 3B) near the boundary with the upper bag body (2B), and the suspension belt (17B, 17B ′) is an annular hook. (There is no equivalent to the annular hook (5B) in FIG. 9 (a)), and the tip of the suspension belt (17B, 17B ′) is connected to the upper part of the bag (2B) on the upper part of the bag (2B). An example is shown in which slits (19B, 19B ′) that can be inserted from the outside to the inside are formed. FIG. 9B shows an example in which the slit (19B) is in the vertical direction, and FIG. 9C shows an example in which the slit (19B ') is in the horizontal direction. From the slit (19B, 19B '), the tip of the suspension belt (17B, 17B') can be inserted into the bag body upper part (2B) from the outside to the inside. As shown in FIG. 2 or 3, the upper part of the bag body (cylindrical lids 2A, 2B) is less likely to be on the inside by hooking a suspension string on the tip of the suspension belt (17B, 17B ′) and pulling upward. It can prevent entering the inside of a trunk part (1A, 1B). Thus, when the flexible container bag (F9) has a quadrangular cylindrical shape (with a bottom) and four suspension belts are provided in the immediate vicinity of the four corners of the quadrangle that constitutes the boundary, a new annular hook must be attached. In addition, by forming the slits (19B, 19B ′), the suspension belt (17B, 17B ′) can be used as an annular hook.

  Other configurations are the same as in the first embodiment (example in FIG. 1B), and in the same manner as in the first embodiment, the upper portion of the bag body does not sag and does not enter the lower portion of the bag body during storage. A flexible container bag that improves work efficiency can be provided.

  Example 7 will be described with reference to FIG. In the first embodiment, an example in which an annular hook (5A, 5B) is attached to the inside of the bag body lower part (1A, 1B and 3A, 3B) and near the boundary with the bag body upper part (2A, 2B) will be described. However, in the seventh embodiment, an example in which the annular hooks (25A, 25B) are attached to the inner side of the upper portion (2A, 2B) of the bag body will be described. FIG. 10A shows an example in which the flexible container bag (F21) has a circular cylindrical shape (with bottom), and FIG. 10B shows an example in which the flexible container bag (F22) has a rectangular cylindrical shape (with bottom). . FIG. 10 (c) shows an example in which the flexible container bag (F21) has a circular cylindrical shape (with a bottom), and the hanging strap (9A) is hung and pulled from obliquely upward on the outside.

  In the flexible container bag (F21, F22), the annular hooks (25A, 25B) are attached to the inner side of the bag body upper part (2A, 2B) using the reinforcing material (26A, 26B). Since the upper part of the bag body (2A, 2B) is softer and lower in strength than the lower part of the bag body (1A, 1B and 3A, 3B), the reinforcing material (26A, 26B) is placed inside and outside the upper part of the bag body (2A, 2B). Although it is used for both, if there is strength, only one side may be used. Since the annular hooks (25A, 25B) are attached to the upper portion (2A, 2B) of the bag body, it is easier to find the annular hooks (25A, 25B) than in the first embodiment, and it is easy to hang a bag or string. Moreover, the bag body upper part (2A, 2B) can be hung outward in a skirt shape from the attachment position of the annular hooks (25A, 25B). Thereby, the upper part (2A, 2B) of the bag body can be prevented from entering the inside of the lower part (1A, 1B and 3A, 3B) of the bag body during storage. In addition, even if the object is inserted to the vicinity of the boundary between the upper part of the bag body (2A, 2B) and the lower part of the bag body (1A, 1B and 3A, 3B), the annular hooks (25A, 25B) can always be visually checked. The opening of the upper part of the bag body (2A, 2B) is easily held at the time of charging or when the excess amount is removed, which is convenient. In addition, since the entire boundary between the upper part of the bag body (2A, 2B) and the lower part of the bag body (1A, 1B and 3A, 3B) can always be visually checked, the amount of material to be charged is set to a certain amount up to the boundary. This is convenient. When the amount to be accommodated is a certain amount, the flexible container bag in which the items to be accommodated are stably stacked.

  In addition, there is a case where it is desired to firmly pack the lower portion of the bag (1A, 1B and 3A, 3B) when the object to be contained is a granular material or a powdery material having a small bulk specific gravity. In such a case, after supplying a large amount of the objects to be stored, the flexible container bag is lifted slightly and lightly struck on the floor, or by gently tapping the surroundings, so that the objects to be stored are lower in the bag body (1A, 1B). 3A, 3B), and the contents are just equal to or below the boundary line between the upper bag body (2A, 2B) and the lower bag body (1A, 1B and 3A, 3B). be able to. If the annular hooks (25A, 25B) are attached to the upper portion (2A, 2B) of the bag body, it is possible to easily supply a larger amount of objects to be accommodated, so that the above-described operation is possible. Become. Workability is also high when you want to pack the soil tightly like a sandbag.

  The other configuration is the same as that of the first embodiment. Like the first embodiment, the upper portion of the bag body is bent during storage and does not enter the lower portion of the bag body, thereby improving the efficiency of the storage operation. Can provide.

  Embodiment 9 will be described with reference to FIG. In the first embodiment, an example in which an annular hook (5A, 5B) is attached to the inside of the bag body lower part (1A, 1B and 3A, 3B) and near the boundary with the bag body upper part (2A, 2B) will be described. However, in Example 9, the annular hook (25A, 25B) is attached to the inner side of the bag body at the boundary between the upper bag body (2A, 2B) and the lower bag body (1A, 1B and 3A, 3B). Will be explained. The annular hooks (25A, 25B) are attached to the inner side of the boundary between the upper bag body (2A, 2B) and the lower bag body (1A, 1B and 3A, 3B) using the reinforcing material (26A, 26B).

  Since the annular hooks (25A, 25B) are attached to the boundary between the upper bag body (2A, 2B) and the lower bag body (1A, 1B and 3A, 3B), the annular hook (25A, 25B) 25B) is easy to find, and it is easy to hang a bag or string. Further, the upper portion (2A, 2B) of the bag body can be hung outwardly from the attachment position of the annular hooks (25A, 25B) in a skirt shape, and the upper portion (2A, 2B) of the bag body is the lower portion of the bag body (1A, 1B). And 3A, 3B) can be prevented from entering inside. In addition, even if the object to be stored is inserted up to the boundary between the upper part of the bag body (2A, 2B) and the lower part of the bag body (1A, 1B and 3A, 3B), the annular hooks (25A, 25B) are always visible, It is convenient because the opening of the upper part (2A, 2B) of the bag body can be kept wide at the time of additional charging. In addition, since the entire boundary between the upper part of the bag body (2A, 2B) and the lower part of the bag body (1A, 1B and 3A, 3B) can always be visually checked, the amount of material to be charged is set to a certain amount up to the boundary. This is convenient.

  The other configuration is the same as that of the first embodiment. Like the first embodiment, the upper portion of the bag body is bent during storage and does not enter the lower portion of the bag body, thereby improving the efficiency of the storage operation. Can provide.

  Embodiment 10 will be described with reference to FIG. In the ninth embodiment, the example in which the annular hook (25A, 25B) is attached to the inner side of the boundary between the upper bag body (2A, 2B) and the lower bag body (1A, 1B and 3A, 3B) has been described. In Example 10, an annular hook (25A, 25B) is attached to the outside of the bag body lower part (1A, 1B and 3A, 3B), and the bag body upper part (2A, 2B) and the bag body lower part (1A, 1B and 3A, 3B) A description will be given of an example in which it is inserted inward through slits (23A, 23B) formed at the boundary. The annular hooks (25A, 25B) are attached to the outside of the bag lower portions (1A, 1B and 3A, 3B) using reinforcing materials (26A, 26B). And it inserts inside through the slit (23A, 23B) formed in the boundary of a bag body upper part (2A, 2B) and a bag body lower part (1A, 1B and 3A, 3B).

Since the annular hooks (25A, 25B) are inserted inward from the boundary between the upper bag body (2A, 2B) and the lower bag body (1A, 1B and 3A, 3B), compared to the first embodiment (25A, 25B) is easy to find, and it is easy to hang a bag or string. Further, the upper portion (2A, 2B) of the bag body can be hung outwardly from the vicinity of the position of the slit (23A, 23B) in a skirt shape, and the upper portion (2A, 2B) of the bag body is lower (1A, 1B) And 3A, 3B) can be prevented from entering inside. In addition, even if the object to be stored is inserted below the boundary between the upper part of the bag body (2A, 2B) and the lower part of the bag body (1A, 1B and 3A, 3B), the annular hooks (25A, 25B) can always be visually checked. It is convenient because the opening of the upper part (2A, 2B) of the bag body can be kept wide at the time of charging. In addition, since the entire boundary between the upper part of the bag body (2A, 2B) and the lower part of the bag body (1A, 1B and 3A, 3B) can always be visually checked, it is convenient for working with the input amount of the container to be fixed up to the boundary. It is.
The other configuration is the same as that of the seventh embodiment. Like the seventh embodiment, the flexible container bag improves the efficiency of the storing operation by forming the upper portion of the bag so that it does not enter the lower portion of the bag when stored. Can provide.

  A configuration example of the hook will be described with reference to FIG. Fig. 13 (a) shows an ordinary annular hook (35a), Fig. 13 (b) shows an annular hook (35b) twisted at the center, and Fig. 13 (c) shows a longer loop with a normal loop at the tip. An annular hook (35) is formed. Further, FIG. 13 (d) shows a normal tape-like hook (35d), and FIG. 13 (e) shows a tape-like hook (35e) composed of a portion sewn and a portion not sewn, and using the portion not sewn as a hook. . In the embodiments described so far, an example using a normal annular hook has been mainly described. However, the hook is not limited to the annular hook, and various hooks can be used.

  In the annular hook (35a) of FIG. 13 (a), the position where the bag is hooked or the string is passed is in the vicinity of the bag body, and the position and shape of the opening of the bag body can be easily controlled. In the annular hook (35b) of FIG. 13 (b), by twisting, the opening of the ring can be increased, and it becomes easier to hook the strap or to pass the string. In the annular hook (35c) of FIG. 13 (c), the hook ring is separated from the bag body, so that it is difficult to damage the bag body with the scissors. In the tape-like hook (35d) of FIG. 13 (d), the hook can be easily attached. In the tape-like hook (35e) in FIG. 13 (e), the force applied to the hook can be dispersed.

  Even when the hooks (35b) to (35e) of FIGS. 13 (b) to 13 (e) are used, the upper portion of the bag body is removed at the time of accommodation, as in the case of using the hooks (35a) of FIG. 13 (a). Thus, a flexible container bag that improves the efficiency of the housing work can be provided by adopting a configuration that does not enter the lower part of the bag body.

  FIG. 14 shows an example in which an object is put into a flexible container bag (F23) using an auxiliary stand. The auxiliary stand (20) is formed by connecting four support columns (20A) with four horizontal bars (20B). One horizontal bar (20B) connects two support columns (20A), and the four horizontal bars (20B) form a quadrangle when viewed from above. The lengths of the four struts (20A) and the four horizontal bars (20B) are adjustable. In the round bottom flexible container bag, the upper portion (2A) of the bag is folded outward at the boundary with the lower portion (1A and 3A) of the bag. Annular hooks (25A) are attached to four locations inside the boundary between the bag upper part (2A) and the bag lower part (1A and 3A) (corresponding to Example 9). The hooked string (29A) is hung on the four annular hooks (25A), and the tip of the hooked string (29A) is tied to the vicinity of the uppermost part of the column (20A) of the auxiliary stand (20). By using the auxiliary stand in this way, the flexible container bag (F25) can be held upright and held in an open state, and the object to be accommodated can be thrown in, and the open state when the container is charged can be kept constant and wide. Input work can be done efficiently.

  Although the present embodiment has been described above, the present invention is not limited to the above embodiment, and it is obvious that various modifications can be made to the embodiment without departing from the spirit of the present invention. is there.

  For example, in Example 4, the string-like hooks (15A, 15B) are attached to the inside of the lower bag body (1A, 1B and 3A, 3B) and near the boundary with the upper bag body (2A, 2B). Although the example has been described, a string-like hook may be attached to the outside of the lower part of the bag body so that it can be inserted into the inside through the slit. Further, the ring-shaped hook may be configured so that no ring is provided at the tip, and the tip may be tied and pulled upward. Moreover, the material of a flexible container bag, a belt attachment structure, etc. are various. Further, in the flexible container bag, the capacity and the weight of the object to be stored are not necessarily proportional. Even if it is small, a product with a large load resistance may be put, and even if it is large, a product with a small load resistance may be put, and there are various types depending on the specifications. The present invention is also applicable to these. In the above embodiment, (6A, 6B, 7B) is cited as a reinforcing material for reinforcing the lower portion of the bag body. However, in a broad sense, a belt including a part of a reinforcing belt or a suspension belt (with a wider width). Bands), tapes (bands narrower than belts), reinforcing cloths (such as squares), and the like are also included in the reinforcing material. Further, the position and number of the hanging belt, the position and number of the hook, the position and number of the belt, the shape of the cylinder, the shape of the slit, and the like can be appropriately changed.

  The present invention is used for storing and transporting objects.
