Description

  The present invention relates to a container liner suitable for a so-called transport container capable of handling bulk transport.

  Conventionally, shipping containers are used to efficiently transport cargo. The transport container is usually formed in a substantially rectangular parallelepiped box shape, and is provided with a loading / unloading port for loading / unloading cargo on the end face in the longitudinal direction. When transporting cargo such as resin pellets and bulk materials such as resin pellets using such a container, a substantially rectangular bag (liner) is stored in the container, and the bulk material is stored in this liner. Filled.

  Here, at the time of unloading, especially unloading, the container 10 is inclined as shown in FIG. 4 and the door (rear door) of the unloading port is opened. Then, while maintaining the posture of the liner, the end of the liner is pulled out from the loading / unloading port and discharged from the cargo discharge port provided at the bottom of the liner.

  In this type of container liner, when unloading, a device has been devised to smoothly discharge the load material from the load material discharge port and reduce the residue of the load material. For example, in the transport container described in Patent Document 1, a so-called triangular plate or the like is provided at the lower corner of the container chamber, and the load is guided to the load discharge port along the surface of the spacer. In another example, a triangular pyramid-shaped air bag (air bag) is attached to the lower corner of the container chamber, and the air bag is inflated when the cargo is discharged.

Japanese Patent Laid-Open No. 10-291583

  However, in a conventional container liner that uses a triangular plate, not only the structure is complicated, but also the installation work is complicated and the overall cost increases. Moreover, although this triangular plate is disposed of after use, such disposal is also complicated. Furthermore, the use of an air bag requires a large-scale air supply device and the like, and there is a problem that the cost is significantly increased.

  The present invention has been made in view of such a situation, and an object thereof is to provide an inexpensive container liner having an excellent function and a relatively simple configuration.

  A container liner according to the present invention is a container liner that is stored in a container chamber so as to have substantially the same volume and is filled with a bulk material, and a reinforcing sheet is attached to a predetermined portion of the liner body on the material discharge port side. The liner body and the reinforcing sheet are stretched so as to form an inclined surface at a lower corner of the container chamber.

  Further, in the container liner according to the present invention, the reinforcing sheet is disposed corresponding to a part of each of the side surface, the floor surface, and the rear surface of the container chamber, and each side of the inclined surface is on each surface. It is set and has a substantially triangular shape.

  The container liner according to the present invention is characterized in that a mounting portion is provided along the upper edge of the reinforcing sheet, and the reinforcing sheet can be supported by the mounting portion.

  According to the present invention, an inclined surface is arranged at the lower corner portion of the container chamber, and unloading can be performed smoothly and accurately by guiding the load material to the load material discharge port along the surface of the inclined surface. Since a spacer, an airbag apparatus, etc. are unnecessary, cost can be reduced significantly.

Hereinafter, preferred embodiments of a container liner according to the present invention will be described with reference to the drawings.
FIG. 1 shows a container 10 and a liner 100 accommodated in the container 10 according to this embodiment. First, the container 10 is formed in a substantially rectangular parallelepiped box shape as shown in the figure, and is provided with a loading / unloading port for loading / unloading cargo on its longitudinal end surface (rear surface). The rear door is attached so that it can be opened and closed. Note that the front and rear of the container 10 are represented by arrows Fr and Rr, respectively.

  Here, in the present invention, the container 10 can be a general general-purpose container (for example, a 20-foot dry container), and this general-purpose container is appropriately modified to realize bulk transportation by a liner mounting method. is there.

  As shown in FIG. 2, the container chamber of the container 10 is formed in a rectangular parallelepiped shape by a front surface 10A, left and right side surfaces 10B, a ceiling surface 10C, a floor surface 10D, and a rear surface 10E. The liner 100 is accommodated almost completely in the container chamber, and the liner 100 is filled with a bulk material (for example, resin pellets).

  The liner 100 is typically formed of a polyethylene material in a bag shape substantially corresponding to the container 10 and has appropriate stretchability. Further, the liner 100 filled with the bulk material is not stable as it is, for example, staggered in the container chamber, but is stably disposed in the container chamber by using a hook or the like as will be described later.

  In order to hang the liner 100, a plurality of suspension rings 12 are usually disposed along the vicinity of the container room ceiling surface 10C. The hanging ring 12 may be U-shaped, elliptical, D-shaped, or the like. Although each surface in the container chamber is formed in a concavo-convex shape, it is preferable that the suspension ring 12 is disposed and fixed in a recessed portion of the front surface 10A or the side surface 10B. On the other hand, a plurality of hooks 101 that are engaged with the suspension ring 12 are provided along the vicinity of the ceiling portion of the liner 100.

  In addition, in the rear part of the liner 100 (corresponding to the rear surface 10E), an upper part is provided with an introduction port 102 for filling the cargo material, and a lower part is provided with a discharge port 103 for discharging the cargo material.

  Now, in the container liner according to the present invention, the reinforcing sheet 1 (FIG. 1, stippled display portion) is attached to a predetermined portion of the liner main body on the discharge port 103 side. The reinforcing sheet 1 is stretched so as to form an inclined surface at the lower corner of the container chamber.

  As shown in FIG. 2, the reinforcing sheet 1 has side portions 1B, a floor portion 1D, and a rear portion 1E corresponding to the side surface 10B, the floor surface 10D, and the rear surface 10E of the container chamber, respectively. The inclined surface 1A (FIG. 2, stippled display portion) is arranged so as to be surrounded by the side portion 1B, the floor portion 1D, and the rear portion 1E. Each side of the inclined surface 1A is set on each surface 10B, 10D, 10E of the container 10 to form a substantially triangular shape. Correspondingly, the liner body itself is formed in a triangular shape substantially the same as the inclined surface 1A of the reinforcing sheet 1 in this example so as to form an inclined surface at the lower corner of the container chamber.

  Here, the reinforcing sheet 1 is typically knitted into a cloth shape using a polypropylene material, and is substantially not stretchable to ensure a predetermined strength. When the reinforcing sheet 1 is attached to the liner 100, the liner 100 is set on a table and attached to a predetermined portion using an adhesive or the like.

  Moreover, the mounting part is provided along the upper end edge of the reinforcing sheet 1, and the reinforcing sheet 1 can be supported by this mounting part. In this embodiment, as shown in FIG. 1, the mounting portion has sleeves 2 and 3 in which the upper end portion of the reinforcing sheet 1 is formed in a small bag shape. For example, a rope 4 is inserted into the sleeve 2, and the rope 4 is hooked by a suspension ring 12. For example, the sleeve 3 may be inserted through the sleeve 3 as shown in FIG. 3, and both ends of the bar 5 may be supported and fixed by the frame 13 of the container 10. The bar 5 can be formed of an iron pipe material.

  In addition, a plurality of retention bars 6 are horizontally mounted below the bar 5 in several upper and lower stages, thereby ensuring a holding function for the liner 100. Both ends of these retention bars 6 can be supported and fixed by the frame 13 of the container 10. Further, a sleeve 7 may be additionally provided on the inclined surface 1A as shown in FIG.

  In the above-described configuration, first, the liner 100 is stored and mounted in the empty container 10 when loading. In this case, the hook 101 of the liner 100 is engaged with the suspension ring 12, and air is injected into the liner 100 to inflate as shown in FIG. Also, the reinforcing sheets 1 are mounted by setting the sleeves 2 and 3.

  In this way, the liner 100 stored in the container chamber is filled with the packing material. In this case, the inclined surface 1A of the reinforcing sheet 1 is formed and arranged at the lower corner portion of the container chamber, and the reinforcing sheet 1 is stretched in this way, so that the liner 100 is formed on both sides of the discharge port 103 as shown in FIG. The shape is retained. When unloading, the trailer is stopped as shown in FIG. The rear door 11 is opened and the cargo material is discharged from the liner 100.

  According to the present invention, the inclined surface 1A is formed and arranged at the lower corner of the container chamber. As described above, the reinforcing sheet 1 is not substantially stretchable and has a predetermined strength, so that the inclined surface 1A is set and held at a predetermined position near both sides of the discharge port 103. Then, unloading can be performed smoothly and accurately by guiding the load material to the load material discharge port 103 along the surface of the inclined surface 1A.

  Although unloading can be performed efficiently as described above, the present invention has a relatively simple configuration in which a part of the liner 100 has a double structure, which eliminates the need for a conventional spacer or airbag device, and reduces the cost. Can be greatly reduced. In addition, it has advantages such as easy handling, excellent usability, and greatly improved work efficiency.

The preferred embodiment of the present invention has been described, but the present invention is not limited to the above-described embodiment, and can be appropriately changed as necessary.
For example, the material of the reinforcement sheet 1 can use the thing equivalent to this other than a polypropylene. Further, the floor portion 1D of the reinforcing sheet 1 may be formed over substantially the entire area of the floor surface 10D of the container chamber 10, for example, in addition to the illustrated example of FIG. Further, the number of the suspension rings 12 can be increased or decreased as necessary, and the arrangement positions thereof can be changed.

It is a perspective view which shows the structural example of the container in this Embodiment, and the liner accommodated in this. It is a perspective view which shows the structural example of the reinforcement sheet which concerns on this invention. It is a rear view of the liner which concerns on this invention. It is a figure which shows the mode at the time of a container inclination.
