Description

  The present invention relates to a container bag that can be used in place of a pallet.

  Currently, wooden pallets are used to transport objects. The pallet is made of wood in a plate shape with a gap into which the forklift claw can be inserted. A pallet with this structure is stacked with objects, and lifted with forklift pawls in the gap. However, the pallet has a drawback that it takes time to process after use. The pallet has a drawback that it takes time and money to transport the goods from the transportation source to the user and then return them to the transportation source. This is because it is large and heavy, and the return cost is high. Pallets that are not returned to the shipping source have the disadvantage that they are more laborious and expensive to dispose of. Furthermore, since the pallet is as heavy as 10 to 15 kg, there is a disadvantage that it is transported together with goods and the transportation cost is increased.

As a container that can be folded small after transportation, a container bag has been developed in which a flexible sheet is formed into a bag shape having an upper opening, and a hanging string is connected. (See Patent Documents 1 and 2)
Japanese Patent Laid-Open No. 2002-240885 JP 2001-180787 A

  The container back of the flexible sheet shown in FIG. 1 is mainly used for transportation of powder particles. The container bag that opens upward and closes the bottom can be filled with powder and transported. However, the container bag having this structure can be transported by pallet but cannot be used conveniently. Since it is sewn in a bag shape that opens upward, even if it can efficiently fill the granular material, it can be stacked and transported on a pallet, such as a boxed or bagged item inside. This is because it is extremely difficult to stack them together. Moreover, even if it takes a lot of effort to stack the objects inside the container bag, there is also a drawback that it is difficult to stably suspend and transport the stacked objects so that they do not collapse. This is because the string 12 is connected to the four corners of the bag 11 and the upper end of the string 12 is connected in a loop as shown in FIG. If the container bag is hung at the four corners in a state where a plurality of objects are stacked vertically and horizontally on the same plane, the bottom surface is bent and the load collapses. When the cargo collapses, it becomes impossible to take out the item from the container bag. Furthermore, there is a drawback that it takes much time to take out the item from the container bag even if the cargo does not collapse.

  The present invention has been developed for the purpose of solving this drawback. An important object of the present invention is that it is possible to simply and easily, efficiently and quickly stack things that can be stacked and transported on a pallet. The object is to provide a container bag that can be easily and efficiently operated.

  The container bag of the present invention includes a rectangular bottom sheet 1 made of a flexible sheet, four open / close sheets 2 made of a flexible sheet connected to four sides of the bottom sheet 1, and an open / close sheet 2. And a hanging string 3 fixed to the outer surface of the bottom sheet 1. The opening / closing sheet 2 has a structure that can be connected so that the side edges of the opening / closing sheets 2 adjacent to each other can be attached / detached by providing detachable connecting tools 4 that can be detachably connected to the side edge portions on both sides. The hanging string 3 is fixed to the outer surface of the bottom sheet 1 in a cross beam shape that is parallel or substantially parallel to the outer peripheral edge of the rectangular bottom sheet 1, and extends from the bottom sheet 1 to the outer surface of the opening / closing sheet 2. Furthermore, the part which protrudes from the opening / closing sheet | seat 2 to an outer periphery is connected with the hanging string 3 currently fixed to the part which the adjacent opening / closing sheet | seat 2 mutually approaches. This container bag is connected in a rectangular tube shape in which the adjacent opening / closing sheet 2 is connected by a detachable connector 4 and the bottom sheet 1 and the opening / closing sheet 2 are opened upward and the bottom surface is closed by the bottom sheet 1. Then, it is suspended and transferred by a hanging string 3 protruding in a loop from the adjacent opening / closing sheet 2.

  The hanging string 3 can be connected to the bottom sheet 1 and the opening / closing sheet 2 by separating the plurality of string bodies 7 from each other and connected in a loop shape outside the opening / closing sheet 2. The hanging string 3 can be connected in a loop on the outside of the opening / closing sheet 2 by connecting a plurality of strings 7 in parallel to the bottom sheet 1 and the opening / closing sheet 2. The detachable connector 4 can be a detachable tape provided with countless locking devices on the surface, or can be a connecting string.

  The container bag of the present invention has a feature that it is possible to stack a transported object simply, easily, efficiently and quickly, stably suspending and moving in a stacked state, and easily taking out easily and efficiently. is there. The container bag of the present invention has a structure in which four open / close sheets connected to the four sides of a rectangular bottom sheet can be connected to each other via a detachable connector to form a rectangular tube with an upper opening. This is because the hanging string is fixed to the outer surfaces of the sheet and the bottom sheet, and is suspended and transferred by the hanging string protruding in a loop from the adjacent opening / closing sheet. In the container bag having this structure, when the side edges of the opening and closing sheets adjacent to each other are not connected, the four opening and closing sheets can be unfolded, so that the transported goods can be efficiently and quickly stacked on the bottom sheet. In addition, in the state where the package is stacked on the bottom sheet, the side edges of the opening and closing sheets adjacent to each other can be connected to form a rectangular cylinder with the bottom sheet and the four opening and closing sheets. By holding the side of the door with an opening and closing sheet, it can be stably suspended while preventing collapse of the cargo. Furthermore, since the side edges of the opening / closing sheets adjacent to each other can be separated and the four opening / closing sheets are unfolded when the package is taken out, the package can be taken out efficiently and quickly.

  Furthermore, the container bag according to the present invention has a hanging string fixed to the outer side surface of the bottom sheet so as to extend from the bottom sheet to the outer side surface of the opening / closing sheet, and projects from the adjacent opening / closing sheet to the outer peripheral edge. Since the lower string is connected in a loop shape, it has the feature that it can be stably suspended and moved. This is because the bottom sheet is hung by a hanging string fixed in a cross-girder shape, not by hanging the four corners of the bag with a string as in a conventional container bag. This structure uniformly supports the entire surface of the bottom sheet with a plurality of vertical and horizontal suspension strings fixed to the bottom surface of the bottom sheet in the form of a cross-beam, and the middle part of the four sides instead of the four corners of the rectangular bottom sheet. Since it is suspended, the bottom sheet can be stably suspended while effectively preventing the stacked transported goods from collapsing.

  Furthermore, the container bag according to the present invention is characterized in that the bottom sheet and the opening / closing sheet are flexible sheets, so that the overall weight can be reduced and the container can be folded and transported compactly after use. Therefore, the transportation cost for returning the container bag to the transportation source after transporting the transportation goods to the user can be reduced.

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment shown below exemplifies a container bag for embodying the technical idea of the present invention, and the present invention does not specify the container bag as follows.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  The container bag shown in the developed view of FIG. 2 includes a rectangular bottom sheet 1 made of a flexible sheet, four open / close sheets 2 made of a flexible sheet connected to four sides of the bottom sheet 1, An opening / closing sheet 2 and a hanging string 3 fixed to the outer surface of the bottom sheet 1 are provided.

  The bottom sheet 1 and the opening / closing sheet 2 are manufactured by cutting one flexible sheet, or are manufactured by sewing the four opening / closing sheets 2 around the bottom sheet 1 and connecting them together. The As the flexible sheet, a plastic sheet reinforced with braided fibers is used. However, the flexible sheet can be a tough sheet used for canvas, tents, and the like. As shown in FIGS. 3 and 4, the bottom sheet 1 is a quadrangle having a size that allows a plurality of packages 8 to be stacked vertically and horizontally. The transported article 8 shown in the figure is a bag filled with a granular material. The bottom sheet 1 is large enough to arrange 3 × 2 bags, which are transported items 8 in the vertical and horizontal directions, or in the horizontal and vertical directions, that is, the number of stacked layers in one stage arranged in the same plane is 6 The size is to be an individual. The bottom sheet 1 used in this state has a side length of 1 to 2 m. However, the container bag of the present invention does not specify the size of the bottom sheet. The bottom sheet can be, for example, 50 cm to 3 m. The bottom sheet 1 in the figure has a flexible sheet as a square. As shown in the perspective view of FIG. 2, which is an example of packaging in which the horizontal shape of the package 8 intersects the package 8 with the rectangular horizontal shape, the container bag intersects the package 8 stacked on the top and bottom at adjacent stacking steps. Can be stacked so that they do not collapse. However, the container bag of the present invention does not specify the bottom sheet as a square. The bottom sheet can also be rectangular.

  Furthermore, the container bag of the present invention does not specify the number of packages arranged in the same plane as six. The number of packages arranged in one stage can be 4 to 12, for example. That is, the container bag of the present invention can be variously changed in the number of packages arranged in one stage according to the shape and size of the bottom sheet, and further, the shape and size of the packages to be stacked. . Furthermore, the container bag of this invention can also change various arrangement | sequences arranged vertically and horizontally according to the number of the packages arranged on the same plane. For example, when four packages are arranged, they can be arranged 2 × 2, and when eight packages are arranged, they can be arranged 2 × 4. Also, it is not always necessary to equalize the number of packages arranged in columns or rows. For example, when arranging five packages, three are arranged horizontally in one column and two are arranged vertically in the other column. Can also be arranged. In other words, the container bag of the present invention can be arranged in any arrangement as long as it arranges a plurality of packages evenly.

  The open / close sheet 2 has a horizontal width as the length of one side of the bottom sheet 1 and a vertical width as the height of the container back. In the illustrated opening / closing sheet 2, the vertical width is ½ of the horizontal width. The vertical width of the opening / closing sheet 2 can be set to 1/4 to 2 times the horizontal width. If the vertical width of the opening / closing sheet 2 is increased, the transported article 8 can be stacked in multiple stages and stably transported. This is because the transported article 8 can be laminated on the inner side surrounded by the opening / closing sheet 2. In the illustrated container bag, the four open / close sheets 2 have the same vertical width. However, in the container bag of the present invention, the height of the four open / close sheets can be slightly different.

  When the transportable sheet 8 is stacked on the bottom sheet 1 and carried in, and is taken out from the bottom sheet 1, the openable / closable sheet 2 is spread out in a flat shape as shown in the development view of FIG. 2. When the transported article 8 is stacked on the bottom sheet 1 and is transported by being suspended, as shown in FIG. 3, both side edges of the opening / closing sheet 2 are connected to each other, the top is opened, and the bottom is placed on the bottom sheet 1. A rectangular tube that is closed with That is, the opening / closing sheet 2 has a structure that can be connected so that both side edges can be detached. In order to realize this, the opening / closing sheet 2 is provided with a detachable connector 4 that can be detachably connected to side edge portions on both sides. The attachment / detachment connector 4 connects the side edges of the opening / closing sheets 2 adjacent to each other so as to be attached / detached. The attachment / detachment connector 4 is an attachment / detachment tape, for example, Velcro (registered trademark), provided with innumerable locking members on the surface.

  The opening / closing sheet 2 connected by the detachable tape has a feature that it can be connected easily and securely without being detached. However, a button, a fastener, a hook, a connection string, etc. can be used for the attachment / detachment connector of the opening / closing sheet. In the illustrated container bag, the detachable connector 4 is fixed from the lower end to the upper end along both side edges of the opening / closing sheet 2. However, the detachable connector can be partially provided on both side edges of the opening / closing sheet.

  The container bag of FIG. 2 is provided with a wrap portion 5 on one side edge of the opening / closing sheet 2 connected to each other in order to wrap and connect the side edge portions of the opening / closing sheet 2 to each other. The wrap part 5 has a structure in which a notch 6 is provided between the side edges of the adjacent opening / closing sheets 2 so that the wrapping part 5 can be bent at right angles to the connected opening / closing sheets 2. The container bag having this structure can be firmly connected in a wide region by laminating the wrap portion 5 on the surface of the adjacent opening / closing sheet 2. The wrap portion 5 is laminated and connected with a detachable tape, or is connected with a button, a hook, or a connecting string. Fasteners, hooks, and connecting strings can be connected so that both side edges of the opening / closing sheet can be detached without providing a wrap.

  FIG. 5 shows an example in which the detachable connector 4 is a connecting string. The detachable connector 4 that is a connecting string has a pair of connecting pieces 4a that are connected to each other, and one end of each connecting piece 4a is attached and fixed to an opposing position of a side edge of the opening / closing sheet 2 that is connected to each other. doing. The connecting pieces 4 a fixed to the facing opening / closing sheet 2 are connected to each other to connect the opening / closing sheet 2. The detachable connector 4 that is a connecting string can reliably prevent the collapsing of the opening and closing sheet 2 during transfer by releasing the connection state of the opening and closing sheet 2 by tightly connecting the connecting pieces 4a. Further, the structure in which the opening / closing sheet 2 is connected by the connecting string has a feature that the play of the container bag can be eliminated by strongly pulling and connecting the connecting string. For this reason, even when packages of various shapes and sizes are packed, there is an advantage that packing can be effectively prevented by packing while absorbing errors in the packages. Furthermore, the container bag of this invention can also provide both a desorption tape and a connection string as a desorption connection tool.

  The hanging string 3 is a single continuous string. The hanging string 3 is fixed to the outer surfaces of the bottom sheet 1 and the opening / closing sheet 2. As shown in the development view of FIG. 2, the hanging string 3 fixed to the outer surface of the bottom sheet 1 is fixed in a cross beam shape that is parallel or substantially parallel to the outer peripheral edge of the rectangular bottom sheet 1. The cross-girder-like hanging strings 3 are fixed so as to cross in the vertical and horizontal directions and extend in two rows. In the illustrated container bag, the distance between the side edge of the bottom sheet 1 and the hanging strap 3 is about 1/4 of the total width of the bottom sheet 1. As shown in FIG. 3, the container bag has a feature that 3 × 2 transportation items 8 are stacked on one stage of the bottom sheet 1, and the transportation object 8 can be held horizontally and suspended. This is because the two vertical and horizontal suspension strings 3 fixed to the bottom surface of the bottom sheet 1 in a cross-beam shape can uniformly support the entire surface of the bottom sheet 1.

  Furthermore, the hanging string 3 is extended and fixed from the bottom sheet 1 to the outer surface of the opening / closing sheet 2. The hanging strap 3 fixed to the opening / closing sheet 2 is fixed in a direction orthogonal to the boundary between the opening / closing sheet 2 and the bottom sheet 1, in other words, parallel to both side edges of the opening / closing sheet 2. However, it goes without saying that the hanging string can also be fixed in a slightly inclined posture with respect to both side edges of the opening / closing sheet. The hanging strap 3 is fixed to the bottom sheet 1 and the opening / closing sheet 2 by sewing, bonding, or both sewing and bonding. The hanging string 3 is suitably a band having a predetermined width. This is because the bottom sheet 1 can be supported in a wide region. However, the hanging string is not band-shaped, and a rope-like one can also be used.

  Furthermore, the hanging string 3 connects portions protruding from the opening / closing sheet 2 to the outer peripheral edge in a loop shape. The hanging string 3 connects the hanging strings 3 that are fixed to portions of the adjacent opening and closing sheets 2 that are close to each other in a loop shape. The container bag having this structure is a rectangular cylinder formed by connecting adjacent opening / closing sheets 2 with a detachable connector 4 and opening the top and closing the bottom surface with the bottom sheet 1 between the bottom sheet 1 and the opening / closing sheet 2. In the state of being connected, the hanging string 3 protruding like a loop from the adjacent opening / closing sheet 2 is suspended and transferred. In this way, the structure in which the hanging straps 3 fixed to the adjacent opening / closing sheet 2 are connected in a loop shape is not the four corners of the quadrilateral bottom sheet 1 but the middle part of the four sides when suspended by this loop part. Therefore, the bottom sheet 1 can be prevented from being bent and can be stably suspended while effectively preventing the stacked transported goods from collapsing.

  Further, as shown in the development view of FIG. 6, the container bag of the present invention connects a plurality of string members 7 to the bottom sheet 1 and the opening / closing sheet 2 in parallel with each other, and loops outside the opening / closing sheet 2. It can also be connected to. With this structure, the large bottom sheet 1 can be reliably supported by the hanging string 3. In the illustrated container bag, one row of hanging strings 3 is composed of two string bodies 7. However, the hanging string can also be composed of three or more strings in one row. In the illustrated container bag, half the area of the bottom sheet 1 is suspended by one line of hanging strings 3 made up of two string bodies 7, so that the distance between the string bodies 7 is about half of the width of the bottom sheet 1. It arranges so that it may become 1/3. This container bag can suspend the bottom sheet 1 with two strings 7 in a well-balanced manner. For this reason, the transported goods stacked on the bottom sheet 1 can be stably suspended while being held in a horizontal posture.

The container bag of the present invention is used as follows.
