Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inner bag for a shipping container, and more particularly, the inner bag is stretched inside a box-shaped container such as a sea container to carry a large amount of powder or other articles. This invention relates to a disposable type inner bag that can store and transport.

Traditionally, raw materials such as powders and granules that do not have a fixed shape have been transported using paper bags such as cement bags or flexible sheet materials such as tarpaulin that are constructed into cylindrical or square bags. Transport bags and the like, which are generally referred to as flexible containers, have come into widespread use. However, paper bags have a problem in terms of strength, and the flexible transport bags have a disadvantage in that the unit transport amount is small because each individual flexible transport bag does not have sufficient volume. However, increasing the size of the transport bag is not desirable from the standpoint of material strength and ease of handling. In particular, when shipping a large amount of powder or granular materials, ease of handling along the shipping route from ejection to unloading at the destination is important. ! The shrine has books that are extremely dog-friendly.

Therefore, as a book that would meet these demands, an inner bag was placed inside a large box-shaped container called a sea container (which is loaded onto a container ship), and powder was added to the inner bag. It has been proposed to fill and transport contents such as granules. However, with conventional inner bags for shipping containers, when the inner bag is stretched inside the container, a plurality of gate-shaped frames are erected at predetermined intervals inside the container, and then the own device is suspended from these frames. Because the container has a supporting structure, the work of installing the interior inside the container is complicated and extremely inefficient.

Therefore, the inventor conducted repeated studies and prototypes in order to obtain an improved inner bag for a shipping container, which can be easily inserted into the interior of a shipping container such as a sea container, and which can quickly and smoothly discharge the contents. As a result, a flexible sheet material is used to form a rectangular parallelepiped-shaped housing body, and a plurality of preferably flexible loop members are provided on the upper longitudinal side edges and the short side edges of the top portion of the housing body. Suspension devices consisting of are sequentially fixed at predetermined intervals, a plurality of content input cylinders are arranged at the center of the top of the case body, and a plurality of content discharge channels are arranged on one transverse side of the case body. Furthermore, a plurality of locks JL, preferably made of flexible loop members, are fixed at predetermined intervals to the lateral edge of the bottom of the bag body adjacent to the other lateral direction @ part of the packaging body to form an inner bag. Then, this inner bag is placed above the inside of the shipping container by a holding member such as a wire (the hanging tool is fully opened to hold it suspended), and the holding tool is used to hold the inner bag at the inner part of the container. By locking to a holding member such as a wire placed below, the attachment work of the inner bag is simplified and the shape of the inner bag is maintained even when the container is tilted to discharge the contents. It was found that the discharge could be carried out smoothly.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an inner bag for a shipping container that can be easily attached to the inside of the shipping container and can be smoothly discharged.

Next, preferred embodiments of the inner bag for a shipping container according to the present invention will be described in detail with reference to the accompanying drawings.

In the accompanying drawings, the inner bag for a shipping container according to the present invention is made of waterproof material, for example, a polyvinyl chloride sheet (PV
It basically consists of a housing body IO formed into a rectangular parallelepiped shape using a flexible and thin sheet material such as O). The upper edge of the outer longitudinal part/l of this mounting body IO and the shorter edge KG of the top part 13 are provided with a large number of suspension devices preferably made of flexible loop members, by high-frequency welding or other sewing. Fix by means such as At the top of the main body IO, there is an inlet/44 m in the center for the contents such as powder and granules in the longitudinal direction.
, /4'b and l-c are opened, and the content input tubes /bua, /Ah and /Ac, which are formed into cylinders from the same flexible sheet material as the main body IO, are attached to these input ports. , Furthermore, by tying each input tube with the attached tightening string/l,
It is possible to close.

A main discharge port Q for the contents stored in the bag and an auxiliary discharge port having a diameter smaller than this main discharge port λ0 are opened in parallel on the side /j of the main body io in the transverse direction. A main discharge tube λH and an auxiliary discharge tube 2 formed of the same flexible sheet material as the main body are attached to each of these discharge ports λO and here.
Install it for 6 minutes and lead it out. In addition, each discharge pipe λ≠, λ
The external protruding end r of t is sealed in advance by a tl+l method such as welding, and a flared OT camphor outer cylinder skirt 30.30 is attached to the outside of the existing discharge cylinder. Also, on the outside of the discharge tube and skirt, there is a tightening string cord for binding.
, are attached respectively.

The other lateral opening of the housing body (i.e. the lateral side i
s) and the lateral edge 1 of the binding c water outer bottom part/7 which is in contact with the book c, there are a large number of AJ pieces, preferably made of flexible loop members, at predetermined intervals, It is fixed by high frequency welding or other means such as bonding.The inner bag configured in this way is folded into a small and compact size before use.

Next 1. The actual use of the inner bag for a shipping container according to the present invention constructed as described above will be explained.

As the transport container in which this inner bag is stretched, a marine container having a structure as shown in FIG. 2 is suitably used. In other words, the container body 3 has a rectangular parallelepiped shape, and one transversal side has an opening that is fully open, and this opening is opened and closed by a pair of double-sided umbrella doors ≠μ and ≠Hiroa. . In addition, at the top of the container, a series of input I/A's provided at the top 13 of the inner bag stored in the container are provided.
A circular opening is provided in R so as to correspond to the opening, and this opening can be sealed with a hatch (not shown). Furthermore, on one side of the pair of double doors,
A small s with one side open corresponding to the auxiliary ejection tube 2 installed in the inner bag.
21 are arranged.

As shown in Figure 2, on the inner wall of the container '3μ constructed in this way, a plurality of hooks 3, generally called lashing eyes, are fixed at wide intervals near the upper edge very close to the ceiling. , (in the case of the example, one at each corner of f)
Three are placed on the top of the inner wall in the steep direction, and seven are placed in the middle on one edge of the inner wall in the short direction. Note that there is no need to provide a hook on the inner edge of the top in the transverse direction on the opening side), wires 3t were looped around each of these seven hooks λ3, and both ends of the wires 3t were finally connected by turnbuckles λj. After that, this turnbuckle Jj is tightened to apply appropriate tension to the wire 3t (2. It is more practical to provide a turnbuckle with an appropriate length of λ to minimize the slack of the wire.) Furthermore, a hook λ3 is similarly fixed at the corner of the lower inner wall in the transverse direction of the container 3, and a wire 31 is stretched between the hooks 23, and a small turnbuckle λ7 is used to secure the same <114t! A tension of I is applied to the wire 3I.

The number of wires 34 and 31 is equal to the number of holders pop generally referred to as eggplant rings, hanging devices provided in the inner bag that is housed and stretched in the container 317, 2, and locking devices 32,
Each wire is slidably disposed on the wire.

Next, the folded inner bag was unfolded and rolled out, and it was carried into container 3≠, and the hanging devices provided in the inner bag were sequentially placed on wire 3 from the back of the container. eggplant ring aO
to hold the inner bag suspended inside the container (third
(see figure).

In addition, the locking tool J provided at the bottom of the inner bag is attached to the eggplant ring 〇 placed on the wire 3 stretched below the container, so that the inner bag will move downward when the container is tilted. Prevent it from shifting to one side. In addition, the material input tube/4 provided at the top 13 of the inner bag is connected to a hook (not shown) provided on the inner circumferential surface of the ceiling of the container 3 via a loop-shaped hanging device (not shown) provided at the base of this tube. (not shown) and is held in place by a circular opening provided in the container (see Fig. 3). Once the inner bag has been stretched inside the container 3μ in this way, close the n-dag and 4Cla.
Start filling the contents such as powder and granules (when the door dug is closed, the auxiliary ejector tube provided in the inner bag is folded, and the small door tube provided in the door container μ is closed). (approximately facing the inner surface)
.

When filling the contents, it is simple to insert a chute (not shown) into one of the charging cylinders/liter, and at this time, the other charging cylinder 1 is opened and used as an internal air venting can. Let it work. Pour the contents into each barrel to ensure uniform filling, and then tighten each barrel with the attached tightening cord/l.
After bundling, push the charging cylinder into the 3μ circular space []4tJ, and seal the opening with a hole (not shown). Now, a large amount of contents is stably stored in the inner bag stored in the container 3≠, and the entire container 3 is transported to the destination by trailer or container ship.

The case where the filled contents are discharged at the destination will be described next. This content is usually discharged by tilting the container 3a to one side using an oil field truck, but since the inner bag inside the container is filled with the contents, the internal pressure is large;
The inner wall and door of Container 31 are included in 1 Export.
It is customary for the inner bag facing the door to burst open all at once due to internal pressure when the door is opened. Therefore, j%$$s
Open the small S with the IC installed to the outside, and pull out the auxiliary discharge tube (the door is closed, of course) through this small door, and open the auxiliary discharge tube. Attach a conduit generally called a spiral wind pipe to the roller (assuming that this conduit is connected to an external hopper, etc.), cut off the sealed end of the auxiliary discharge pipe, and pipe the contents. released through. At this time, since fine powder and the like rise outside in the form of smoke, it is preferable to cover the outer periphery of the conduit with the outer cylinder skirt 30'f and tighten it with the string 2t.

As described above, according to the inner bag for a shipping container according to the present invention, the outer edge, top edge, and bottom edge of the inner bag are attached to the container body and held suspended, so that the contents can be easily discharged. Therefore, even if the container body is tilted, it is possible to avoid inconveniences such as the inner bag slipping down inside the container and shifting to one side, making the discharge work smoother, and the inner bag can be easily installed inside the container. This has advantages such as ease of use.

Although the preferred embodiment of the inner bag for a shipping container according to the present invention has been described above, the present invention is not limited to this embodiment, and various designs may be made without departing from the spirit of the present invention. Of course, modifications can be made.
