Description

  TECHNICAL FIELD The present invention relates to a flexible container that can stably and stably support columns for stacking.

  At present, in a wide range of industries, flexible containers are used for transporting and storing various substances (for example, powders and granules such as resin pellets, chemical products, inorganic substances, minerals, grains, feeds, etc.). A flexible container generally includes a container body that is open up and down, an upper surface of the main body that covers an open upper portion of the container body, a lower surface of the body that closes an open lower portion of the container body, and a suspension belt attached to a side surface of the container body. Consists of A sealable inlet is provided in a central region of the upper surface of the main body, and a sealable outlet is provided in a central region of the lower surface of the main body as necessary.

  There is a demand for stacking flexible containers from the viewpoint of effectively utilizing the space as much as possible when storing and transporting the flexible containers with the contents filled therein. As a method of stacking the flexible containers, a method of setting up a support at a place where the flexible container is to be installed, installing a plate such as a pallet thereon, and placing the second-stage flexible container thereon can be considered. . At this time, in consideration of the stability of the support, it is preferable to connect the flexible container and the support and stably fix each other.

  Patent Literature 1 discloses a cylindrical outer container formed of a strong base cloth and having a plurality of support members extending in the vertical direction fixed to a peripheral wall portion, and held in tight contact with the inside of the outer container. And a top cover and a bottom cover for closing the upper and lower surfaces of the outer container, respectively, and the whole is formed into a cylindrical shape by the internal pressure exerted by the filled fluid on the inner peripheral wall of the outer container. A container bag is described which is shaped and self-supporting. As a method of fixing the support member, use a stud, a screw, a bolt and a nut, stop the support member with a cloth, sew the support member, or wrap the support member in the outer container material and then stop with the stud. A method is described.

  In Patent Document 2, a plurality of pillars are vertically arranged at intervals on a body peripheral wall of a cylindrical or prismatic woven bag body, and the pillars are provided to prevent breakage. For this reason, there is described a container bag characterized in that the periphery thereof is covered with a reinforcing member, and is tightly fixed to the bag body over the entire length. The most preferable method of fixing the strut member is to cover the strut applied to the bag body with a fabric and sew the fabric to the bag body, and in addition, it is dispersed in the longitudinal direction of the strut. A method is described in which the connecting means is attached to the bag body via a provided connecting part, and the connecting part is provided with a column protection means using a fragile member (for example, a tying string) or an elastic member (for example, a rubber ring).

  Patent Literature 3 has four columns on four sides of a carriage, and at least one of the columns includes a plurality of loading amount indicating units installed at different heights according to a loading target. Is described. Then, on the carrier, a bag body with a belt for lifting is placed, and the belt is connected to the bag connecting member of the support, so that the bag body is in a state where the upper opening is open. It is stated that it will be maintained.

  However, the methods described in Patent Literatures 1 and 2 basically fix the column to the container bag in advance, and do not consider removing the column afterwards. It is difficult. In addition, the pillars are outside the container bag body, the pillars are made of square pillars, and they are fixed outside the pillars with strings, etc. Not only wasteful space is generated, but also when the arbitrary one container bag is pulled out, the angular irregularities may be caught on each other and fall down. When using the tying strap or rubber ring described in Patent Document 2, it is thought that it is possible to attach and detach the strut according to the situation, but the strut will not be stable and will wobble. It was difficult to stack container bags. The column of the transport trolley described in Patent Literature 3 is not for stacking the objects in the first place, and the objects lack the stability even if the objects are fixed to the columns.

  Then, an object of this invention is to provide the flexible container which can fix and fix the support | pillar for stacking in a detachable manner, and can stabilize it.

The present invention provides a container body having a vertically opened container body,
A top surface of the main body in which an inlet for communicating between the inside and the outside of the container main body is formed, while closing an open upper portion of the container main body,
Having a lower surface of the main body closing a released lower portion of the container main body,
On the side surface of the container body, a plurality of column holding members having a hook-and-loop fastener are provided,
By connecting the hook-and-loop fastener of the strut holding member to a pair of hook-and-loop fasteners in a state where the strut is arranged on the side surface of the container body, the strut is held by the strut holding member in a flexible state. Container.

  Advantageous Effects of Invention According to the present invention, it is possible to provide a flexible container that can stably and stably support columns for stacking.

It is a perspective view showing the example of composition of the flexible container concerning the present invention. It is a top view showing the example of composition of the flexible container concerning the present invention. It is a top view showing the example of composition of the state where the pillar was attached to the pillar holding member of the flexible container concerning the present invention. It is a front view showing the state where flexible containers concerning the present invention were piled up.

  The configuration of a flexible container according to an embodiment of the present invention is shown in FIG. 1 (perspective view) and FIG. 2 (plan view). The flexible container 1 includes a substantially cylindrical container main body 11 whose upper and lower sides are opened, a main body upper surface 12 that covers an opened upper part of the container main body 11, and a main body lower surface 13 that closes an opened lower part of the container main body 11. Have.

  The container body 11 is a tubular body made of a flexible material. The cylindrical body that forms the container body 11 may be seamless, or may be formed by winding one sheet material, joining the ends together, and forming a cylindrical shape. The container main body 11 may have a substantially cylindrical shape having a horizontal cross-sectional shape of a circle or an ellipse, or may have a substantially rectangular cylindrical shape having a horizontal cross-sectional shape of a polygon or a polygon with rounded corners. Examples of the polygon include a triangle having three corners, a quadrangle having four corners, a pentagon having five corners, and a hexagon having six corners. A quadrangle is preferable, and a rectangle or a square is more preferable. The diameter of the container body 11 (tubular body) (when the container body 11 is a cylindrical body other than a cylinder, means the diameter of a circumscribed circle in a horizontal cross section. The same applies hereinafter). It can be appropriately set in consideration of the amount and the like, and is usually 600 to 1400 mm. The diameter of the container body 11 is often 900 mm, 1000 mm, or 1100 mm as a standard product. The height H of the container body 11 (tubular body) can be appropriately set in consideration of the design filling amount of the flexible container 1 and the like, and is usually set to 700 to 1500 mm. The height of the container body 11 is often 1000 mm, 1050 mm, 1100 mm, or 1150 mm in a standard product.

  As the material of the cylindrical body constituting the container body 11, various materials conventionally used for the cross-shaped or running-type flexible container 1 can be used. Specific examples of the material used for the cross-shaped flexible container 1 include a yarn fabric obtained by weaving a flat yarn made of a polyolefin resin such as polyethylene or polypropylene as a warp and a weft with a loom. Specific examples of the material used for the running-type flexible container 1 include woven fabrics of resin such as ethylene-vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), various rubbers, polyethylene, and the like. Is mentioned.

  The opened upper part of the container body 11 is closed by the body upper surface 12. That is, the outer periphery of the main body upper surface 12 is formed substantially identical to the outer periphery of the upper portion of the container main body 11, and the outer periphery of the main body upper surface 12 and the outer periphery of the upper portion of the container main body 11 are connected. The type of connection can be appropriately set in consideration of ease of making the flexible container 1, strength, and the like. For example, the container main body 11 formed separately and the main body upper surface 12 can be connected by sewing, bonding, fusion, or the like. Further, as will be described later, when the main body upper surface 12 is a cylindrical body having substantially the same cross-sectional shape as the container main body 11, the container main body 11 and the main body upper surface 12 can be integrally formed. Specific examples of the material forming the main body upper surface 12 include the materials exemplified as the material forming the container main body 11, but it is preferably the same as the material forming the container main body 11.

  The main body upper surface 12 is formed with an inlet 12x for communicating the inside and the outside of the container main body 11 with each other. That is, the material stored inside the container main body 11 can be injected from the injection port 12x, and the material stored inside the container main body 11 can be taken out. Examples of a method of taking out the material stored inside the container body 11 include a method of sucking from above and a method of turning the flexible container 1 upside down. The shape and size of the inlet 12x can be appropriately set in consideration of the design filling amount of the flexible container 1 and the like. For example, the injection port 12x has a substantially cylindrical shape or a substantially rectangular tube shape with a diameter of 300 to 700 mm, and a standard product often has a substantially cylindrical or substantially rectangular tube shape with a diameter of 450 mm, 500 mm, or 550 mm. In this case, the height of the injection port 12x is usually 300 to 700 mm, and the standard product is often 500 mm, 580 mm, or 590 mm. Further, for example, the upper surface 12 of the container may be a tubular body having substantially the same cross-sectional shape as the container main body 11, and the opened upper portion of the container main body 11 may be closed by folding the upper surface 12 of the main body. The structure and the like of the main body upper surface 12 are not particularly limited, but from the viewpoint of effectively utilizing the space, it is preferable that the main body upper surface 12 be flat when the injection port 12x is closed.

  The released lower part of the container main body 11 is closed by the main body lower surface 13. That is, the outer periphery of the main body lower surface 13 is formed substantially identical to the outer periphery of the lower part of the container main body 11, and the outer periphery of the main body lower surface 13 and the outer periphery of the upper part of the container main body 11 are connected. The type of connection can be appropriately set in consideration of ease of making the flexible container 1, strength, and the like. For example, the container body 11 formed separately and the body lower surface 13 can be connected by sewing, bonding, fusion, or the like. Further, as will be described later, when the lower surface 13 of the main body is a cylindrical body having substantially the same cross-sectional shape as that of the container main body 11, the container main body 11 and the lower surface 13 of the main body can be integrally formed. Specific examples of the material forming the main body lower surface 13 include the materials exemplified as the material forming the container main body 11, but it is preferable that the material is the same as the material forming the container main body 11.

  Depending on the use of the flexible container 1, a discharge port (not shown) for communicating the inside and outside of the container body 11 may be formed on the lower surface 13 of the body. In this case, the material stored inside the container body 11 can be discharged from the discharge port. The shape and size of the discharge port can be appropriately set in consideration of the design filling amount of the flexible container 1 and the like. For example, the outlet is formed in a substantially cylindrical shape or a substantially rectangular tube shape having a diameter of 300 to 700 mm, and a standard product is often formed in a substantially cylindrical shape or a substantially rectangular tube shape having a diameter of 450 mm, 500 mm, or 550 mm. In this case, the height of the discharge port is usually 300 to 700 mm, and in a standard product, it is often 500 mm, 580 mm, or 590 mm. Alternatively, for example, the lower surface 13 of the container may be a tubular body having substantially the same cross-sectional shape as the container main body 11, and the opened lower portion of the container main body 11 may be closed by folding the lower surface 13 of the main body.

  In the present invention, a plurality of column holding members 14 are provided on the side surface of the container body 11, and a hook-and-loop fastener is arranged on at least a part of the surface of the column holding member 14. Then, by connecting the hook-and-loop fastener of the column holding member 14 to a pair of surface fasteners, the column 2 is held by the column holding member 14. That is, the hook-and-loop fastener included in the column holding member 14 and the hook-and-loop fastener that can be engaged with the hook-and-loop member are arranged at positions where the column 2 can be held by the column holding member 14. By doing so, regardless of the shape and size of the column 2, the column 2 is stably held by the column holding member 14, and the column 2 can be fixed to the flexible container 1 and stabilized. In addition, since the support | pillar fixing member 14 is latched by the hook-and-loop fastener, the support | pillar 2 becomes easily removable.

  The strut holding member 14 may be any member that can hold the strut 2 by connecting the hook-and-loop fastener disposed on the surface thereof to a hook-and-loop fastener that forms a pair with the hook-and-loop fastener. From the viewpoint of stabilization, it is preferable that the column holding member 14 is vertically attached to the side surface of the container body 11. For example, in the flexible container 1 shown in FIGS. 1 and 2, as the column holding member 14, a first belt member 14 a having a first hook-and-loop fastener 15 a and a second face forming a pair with the first hook-and-loop fastener 15 a A set with the second belt member 14b having the fastener 15b is attached to the side surface of the container body 11 in the vertical direction. In this case, by connecting the first hook-and-loop fastener 15a and the second hook-and-loop fastener 15b in a state where the column 2 is arranged on the side surface of the container body 11, the first belt member 14a and the second belt member 14b are connected. The column 2 is held by the column holding member 14 (see FIG. 3), and the column 2 can be fixed to the flexible container 1 and stabilized. Conversely, since the flexible container 1 is fixed to the support 2, the shape of the container main body 11 itself is maintained, and there is an effect of preventing the container main body 11 from falling over, and the weight of the support 2 is added. Accordingly, friction between the bottom surface (the lower surface 13 of the main body) of the container main body 11 and the floor surface increases, and there is also an effect of preventing the installation location of the container main body 11 from shifting during transportation. At the same time, since the flexible container 1 is installed in a more upright form than the case where the flexible container 1 is installed alone, only an arbitrary flexible container 1 is moved from the flexible containers 1 arranged in a plurality of rows in a plane. However, it can be said that the adjacent flexible container 1 does not fall down and is excellent in safety. In FIG. 3, the first belt member 14 a and the second belt member 14 b are simply connected so as to surround the column 2. However, when the column 2 having a small diameter is used, the first belt member 14 a and the second belt member 14 b The belt member 14a and / or the second belt member 14b may be connected in a partially folded state. Further, since the first belt member 14a and the second belt member 14b are locked by the first hook-and-loop fastener 15a and the second hook-and-loop fastener 15b, the support | pillar 2 becomes easily removable.

  The size of the column holding member 14 (the first belt member 14a and the second belt member 14b) may be appropriately set in consideration of the state where the column 2 is held by the column holding member 14, In consideration of the stability of the held column 2, the width H in the height direction of the column holding member 14 is preferably 400 to 1000 mm, more preferably 500 to 900 mm, and more preferably 600 to 800 mm. Is more preferred. If the width H in the height direction of the column holding member 14 is within the above range, the column 2 is held by the column by the column holding member 14, and the stability of the column 2 is increased. The length of the column holding member 14 in the horizontal direction may be appropriately set in consideration of the thickness of the column to be fixed and the like.

  The installation location and area of the hook-and-loop fastener in the support holding member 14 (the first belt member 14a and the second belt member 14b) are limited as long as the support 2 can be held by connecting to the hook-and-loop fastener forming a pair with the hook-and-loop fastener. Can be set as appropriate. For example, the first hook-and-loop fastener 15a may be arranged on one entire surface of the first belt member 14a, and the second hook-and-loop fastener 15b may be arranged on one entire surface of the second belt member 14b. However, in consideration of ease of attachment and detachment and cost, a first hook-and-loop fastener 15a having a width of 10 to 80 mm is horizontally provided on the surface of the first belt member 14a like the flexible container 1 shown in FIGS. A plurality of (four in the flexible container 1 shown in FIGS. 1 and 2) are installed so as to extend in the direction, and a second surface fastener having a width of 10 to 80 mm is provided on the surface of the second belt member 14b. It is preferable that a plurality of (four in the flexible container 1 shown in FIGS. 1 and 2) are installed so that 15b extends in the horizontal direction.

  The mounting position of the column holding member 14 (the first belt member 14a and the second belt member 14b) on the side surface of the container body 11 in the height direction is determined in consideration of other members installed on the side surface of the container body 11. What is necessary is just to set suitably. For example, a suspension belt (not shown) for lifting and moving the flexible container 1 is often provided on the side surface of the container body 11, and the connection position of the suspension belt is near the upper end of the side surface of the container body 11. It is preferable that the connection position of the column holding member 14 is near the lower end of the side surface of the container body 11. In addition, the installation position of the suspension belt when the suspension belt is installed on the side surface of the container body 11 is not particularly limited.

  In particular, the mounting position of the first belt member 14a and the second belt member 14b on the side surface of the container body 11 is determined by connecting the first hook-and-loop fastener 15a and the second hook-and-loop fastener 15b. It may be set appropriately in consideration of the state in which the column 2 is held by the column holding member 14 including the member 14a and the second belt member 14b. However, in consideration of the stability of the held column 2, the container The distance D between the mounting position of the first belt member 14a and the mounting position of the second belt member 14b on the side surface of the main body 11 is preferably 100 to 500 mm, and more preferably 200 to 400 mm.

  The number of the column holding members 14 provided on the side surface of the container main body 11 may be adjusted in consideration of the weight of the contents of the container main body 11, the strength of the column 2, and the required stability of the flexible container 1; 2 or more), and it is more preferable that the weight is an even number from the viewpoint that the weight is uniformly applied to the whole (left or right or front and rear). Further, the number of the column holding members 14 is preferably 3 or more and 10 or less, more preferably 4 or more and 8 or less, and still more preferably 4 or 6. When the container main body 11 has a substantially rectangular cylindrical shape, it is preferable that the number of the column holding members 14 provided on the side surface of the container main body 11 is the same as the number of the corners of the substantially rectangular cylindrical shape. Then, in a state where the columns 2 are held by each of the plurality of column holding members 14, it is preferable that the plurality of columns 2 are arranged at substantially equal intervals along the outer periphery of the container body 11 as viewed from above. For example, in the flexible container 1 shown in FIGS. 1 and 2, four support members 14 (a first belt member 14 a and a second belt member 14 b) are provided on the side surface of the container body 11, and the four In a state where the columns 2 are held by the column holding members 14, the four columns 2 are arranged at substantially equal intervals along the outer periphery of the container body 11 as viewed from above. In this way, when the pallet 3 is installed on the upper part of the plurality of columns 2, the pallet 3 is in a very stable state, and the flexible container 1 is stacked on the pallet 3 as shown in FIG. Then, the flexible containers 1 can be stacked. Stacking can be arbitrarily stacked in three or more stages by repeating the installation of the flexible container 1 and the pallet 3. In addition, the stability of the flexible container 1 is further improved by fixing or penetrating both ends of the support 2 to the pallet 3. If the contents of the flexible container 1 do not have a fixed form such as fine powders, gels, or liquids, the pallet 3 is removed because no irregularities are formed on the upper part of the flexible container 1. Even without using, the flexible container 1 can be directly loaded, and the space can be saved because the pallet 3 is omitted.

  In particular, when the container main body 11 has a substantially cylindrical shape and four side column holding members 14 are provided on the side surface as in the flexible container 1 shown in FIGS. It is preferable that four pillars 2 are arranged inside the square S circumscribing the container body 11 when viewed from above in a state where the pillars 2 are held in each of the fourteen. In this manner, when the flexible containers 1 are stacked and aligned in the front, rear, left, and right directions, the four columns 2 fixed to the flexible container 1 are arranged in a dead space region of the aligned flexible containers 1. Therefore, the space can be effectively used. The square S is usually a square, but may be a rectangle depending on the shape of the container body 11. When the container body 11 has a substantially rectangular cylindrical shape, the position of the column holding member 14 provided on the side surface of the container body 11 is a polygon having a horizontal cross-sectional shape utilizing the flexibility of the fabric of the container body 11. Alternatively, each corner of a polygon with rounded corners can be used, but from the viewpoint of preventing the torso portion from bulging, the central part of each side of the polygon having a horizontal cross-sectional shape or a polygon with rounded corners Is preferred.

  The column 2 may have any cross-sectional shape, but from the viewpoint that the column 2 and the column holding member 14 are more closely adhered to each other, the cross-sectional shape of the column 2 should be such that the portion where the column 2 closely contacts the column 2 is at least seamless. Often, circular (including semicircular) or conical shapes are preferred. The material of the column 2 may be wooden, metal, resin, paper, and the size thereof may be appropriately selected according to the purpose. A cylindrical paper tube of ~ 250 mm can be used.

  With the flexible container of the present invention having the above-described configuration, the columns can be detachably fixed and stabilized, and the flexible containers can be stacked using the columns. Further, when the flexible containers are stacked, the load applied to the lower flexible container can be reduced, and the lower contents can be prevented from solidifying due to the load from the upper stage.
