Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to containers loaded with cargo and transported by aircraft, vehicles, ships, etc.

"Prior Art" Among such containers, so-called cold containers with particularly excellent heat insulation properties and ordinary so-called dry containers have conventionally been used as exclusive products for each side.

That is, a conventional cold storage container has a box shape with a heat insulating material arranged on the inner surface, and this heat insulating material is not intended to be removed, and the container as a whole cannot be folded from its box shape.

On the other hand, a dry container is an ordinary box-shaped container that is widely used, and no particular consideration has been given to its insulation properties. It should be noted that among these dry containers, those that have changed from a box-like shape to a collapsible one have been developed and used in the past.

"Problems to be Solved by the Invention" By the way, the following problems have been pointed out with such conventional containers.

First, conventional cold storage containers and dry containers have different structures and are separate dedicated products. Therefore, it is generally necessary to have two types of containers, and they are used depending on the type of cargo.
There were problems with efficiency, cost, etc.

Second, conventional refrigerated containers cannot be folded. Therefore, when not in use and not loaded with cargo, a large space is required for storage and storage, and transportation also takes up space, which also poses problems in terms of efficiency and cost.

In the conventional example, such a point was pointed out.

In view of these circumstances, the present invention has been made to solve the problems of the conventional methods described above, and it is possible to install a heat insulating mat inside the collapsible container body, thereby allowing it to be used as a dry container as needed. To provide a refrigerated container that can be used, and can be folded and compacted when not in use to be stored, stored, and transported, so that it does not take up much space, and which can be easily realized.

"Means for Solving the Problems" The technical means of the present invention to achieve this objective are as follows.

This cold storage container includes the following container body and a heat insulating mat.

The container body has a collapsible box shape and is made up of an assembled outer panel.

The heat insulating mat has a foldable box shape and is made of a flexible material with heat insulating properties.

In each box-like state, the heat insulating mat can be installed inside the container main body along the inner surface thereof.

"Function" Since the cold storage container according to the present invention is comprised of such means, it functions as follows.

First, only the container body is unfolded into a box shape, and cargo is loaded inside to be used as a normal dry container. In this case, the heat insulating mat is folded and stored separately.

On the other hand, after the container body is expanded into a box shape, a heat insulating mat is expanded and attached along the inner surface of the container.
Used as an original refrigerated container. Frozen cargo will then be loaded inside.

When the container is not loaded with cargo, that is, when it is not used as a container, the container body and insulation mat are
Both can be folded for storage and storage.

Since it is transported, it does not take up a lot of space.

Furthermore, these points can be easily realized with a simple configuration.

"Example" The present invention will be described in detail below based on the example shown in the drawings.

First, the structure will be explained in the order of the container body and the heat insulating mat.

FIG. 1 shows an embodiment of a cold storage container according to the present invention.
It is an external perspective view. FIG. 2 is a plan sectional view of the main part of FIG. 1. FIG. 3 is an explanatory diagram of the operation of folding the container body from the box shape. FIG. 4 is a perspective view of the folded state. FIG. 5 is a plan sectional view of the main part of FIG. 4.

The container body looks like the following.

That is, the container main body 1 has a foldable box shape, and has an outer panel assembled thereto.

Reference numeral 2 denotes a back plate of the container body 1. In the illustrated example, the sleeve portion 31 of the left side plate 3 is fixed at right angles to the left side of the back plate 2, and the main body portion 3 of the left side plate 3 is fixed to the sleeve portion 3I. □ is pivotally mounted on a vertical rotation axis so that it can rotate 90 degrees. A right side plate 4 is fixed to the right side of the back plate 2 at a right angle. Above and below the back plate 2 are a top plate 5 and a floor plate 6, each with a horizontal rotation axis.
70 degrees.

It is pivoted so that it can rotate 90 degrees. Further, a door 7 is pivotally attached to the front side of the right side plate 4 by a hinge portion 8 so as to be rotatable by 270 degrees about a vertical rotation axis. 9 in the figure is a heat insulating mat, which will be described later.

Further, as shown in FIG. 2, for example, the left side panel 3 has an exterior panel 33 and an interior panel 34 covered with reinforcing materials 3. Although it has a double-panel structure provided with a panel in between, it may be constructed of a single plate, regardless of the illustrated example. Back plate 2. Right side plate 4. Top plate 5. Floorboard 6. The same applies to the door 7, etc. Now, the container main body 1 is unfolded and fixed into a box shape as shown in FIG. Further, by folding from this state as shown in FIG. 3, it is fixed in the folded state shown in FIG. 4.

The container body 1 looks like this.

Next, the heat insulating mat 9 will be described.

FIG. 6 is a perspective view of the heat insulating mat 9 in a box-like unfolded state, and FIG. 7 is a perspective view of the heat insulating mat 9 in a folded state.

The heat insulating mat 9 has a foldable box shape and is made of a flexible material with heat insulating properties. and the container body
In this box-shaped state, the heat insulating mats 9 can be installed inside the container body 1 along the inner surface thereof.

That is, the heat insulating mat 9 is made of, for example, a resin foam material covered with aluminum foil.

It is foldable and is sewn in advance into a box shape, for example, and an opening/closing part 11 is attached to the entrance/exit 10 with a fastener 12 so that it can be opened and closed.

Further, FIG. 8 is a perspective view of the members used for attaching the heat insulating mat 9 to the container body 1, in which (1) the figure shows the locking receiver 13, and (2) the figure shows the locking tool 14. .

That is, on the inner surface of the top plate 5 of the container body 1, a plurality of locking receivers 13, for example, hooks, are hung.

Then, a locking tool 1 is attached to the outer surface of the top of the heat insulating mat 9 at a portion corresponding to the case where it is unfolded into a box shape.
4 are provided in a protruding manner, for example, by sewing. By hooking the ring portion 14+ provided on the locking tool 14 onto the locking receiver 13, the heat insulating mat 9 can be easily attached and fixed by locking along the inner surface of the container body 1. Also, its removal is easily accomplished by releasing such a lock.

Note that the heat insulating mat 9 may be attached to the container body 1 in the following manner, regardless of the illustrated example.

That is, first, a plurality of locking devices 14 are provided not only on the top of the heat insulating mat 9 but also on the outer surfaces such as both sides and the back, and correspondingly, the locking devices 14 are provided on the left side plate 3, right side plate 4, etc. of the container body 1. A plurality of locking receivers 13 may also be provided on the inner surface of the top plate 5 and the like. And when it is expanded into a box shape,
By locking these locking tools 14 to the locking receivers 13, the heat insulating mat 9 can be more securely attached to the container body 1. Therefore, there is an advantage that loading and unloading, loading, etc. of luggage is further facilitated and stabilized.

Second, the illustrated locking receiver 13 is used for attaching both.
And regardless of the locking tool 14, Velcro tape.

Possible methods include providing hooks, rings, and other various members between the two.

The heat insulating mat 9 has this structure.

The cold storage container according to the present invention is as described above.

The operation etc. will be explained below.

First of all, how to use it as a normal dry container is as follows.

That is, in this case, only the container body 1 is used, and the heat insulating mat 9 is folded and stored separately as shown in FIG.

In the illustrated example, the main body part 3□ of the left side plate 3 of the container body 1 is on the left side, the top plate 5 is on the front side, and the floor plate 6 is also on the front side.
Then, the door 7 is rotated in both directions. As a result, the container body 1 is unfolded from the folded state shown in FIG. 4 to the box-like state shown in FIG.

The container body 1 is fixedly held in this box shape,
After the cargo is loaded inside, it will be transported.

In this way, it can be used as an ordinary dry container.

On the other hand, as a cold storage container, it is used as follows.

That is, after expanding the container body 1 into a box shape,
By expanding and attaching a heat insulating mat 9 along its inner surface into a box shape, it can be used as an original cold storage container. In the illustrated example, this attachment is performed by locking the locking tool 14 on the top of the heat insulating mat 9 to the inner surface of the top plate 5 of the container body 1.

In this way, the container main body 1 and the heat insulating mat 9 are both fixedly held in a box-like double structure, and after frozen cargo is loaded therein, the container is transported.

In this way, it is used as a cold storage container.

Next, when not in use:

When no cargo is loaded, that is, when the container is not used as a container, the container body 1 and the heat insulating mat 9 are both folded.

That is, in the illustrated example, the main body portion 3t, top plate 5, floor plate 6, door 7, etc. of the left side plate 3 of the container body 1 are rotated and folded in the opposite direction to the direction in which they are unfolded. Then, the container body 1 is folded from the state shown in FIG. 1, through the state shown in FIG. 3, and then to the state shown in FIG. 4. Also, the heat insulating mat 9 is
It is folded from the state shown in the figure to the state shown in FIG.

In this way, the container main body 1 and the heat insulating mat 9 are folded, stored, stored, and transported as an empty container, so they do not take up much space.

This is what it looks like when not in use.

Furthermore, each of the above points can be easily realized with a simple configuration.

The above is the explanation of the operation, etc.

Firstly, in the illustrated embodiment, as described above (in the container body 1, the sleeve portion 3 of the left side plate 3 is attached to the back plate 2).
．． is fixed, and a right side plate 4 is fixed to the back plate 2.

Therefore, when the container body 1 is folded, its cross section forms an abbreviated shape centered on the back plate 2 and the right side plate 4, as shown in Fig. 4, so that it stands on its own without any support and does not fall over. It is kept standing.

Therefore, it has the advantage of being easy to store, store, and transport.

Second, on the other hand, regardless of the illustrated example, the left side plate 3, which has the sleeve portion 31 and the main body portion 3□ integrally formed, is pivotally attached to the back plate 2 of the container body l by a vertical rotation wheel, Further, the right side plate 4 may also be pivotally attached to the back plate 2 by a vertical rotation wheel.

In this way, the container main body 1 becomes more compact in the folded state, which has the advantage that it takes up less space for storage and storage, and the structure is also simplified.

Thirdly, by assembling the outer panel of the container body 1,
The method of forming the foldable box shape is not limited to these, and various conventionally known folding methods can be considered.

Fourth, in the illustrated embodiment, as described above, the left side plate 3 of the container body 1 has a sleeve portion 3 fixed to the back plate 2.
have.

Therefore, when the container body 1 is folded,
As shown in FIGS. 4 and 5, an internal storage space 15 is formed. That is, the back plate 2 and the sleeve portion 3 of the left side plate 3 fixed at right angles thereto. Furthermore, an internal storage space 15 is formed inside by the main body part 3□ which is perpendicular to this.

Therefore, by sandwiching and storing the folded heat insulating mat 9 in such an internal storage space 15, there is an advantage that the entire storage can be made more compact and less space is taken up.

"Effects of the Invention" The cold storage container according to the present invention has the following advantages by being able to attach a heat insulating mat inside the collapsible container body. In other words, firstly, it can be used as a refrigerated container or a dry container depending on the type of cargo, eliminating the need to keep two types of containers.
Since it can be used for both purposes, it is extremely superior in terms of efficiency and cost. Secondly, when not in use, it is folded and compacted for storage, storage, and transportation, so it does not take up much space and is excellent in terms of efficiency and cost. Third
Moreover, these can be easily realized with a simple configuration. In this way, the problems that existed in this type of conventional example are completely eliminated, and the effects it brings are remarkable and great.
