Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a container lining insulation enclosure that maintains the inside of various containers at an appropriate temperature for a long period of time.

<Prior Art> Conventionally, cold box pallets and the like, which are provided with a heat insulating section around the periphery, have been used to keep stored objects cold or warm at an appropriate temperature for long periods of time by shielding them from heat and light.

In other words, in order to maintain stored objects at an appropriate temperature without a refrigeration system, pallets or containers surrounded by a heat insulating material such as urethane foam or styrene foam are used.
Disadvantages include that precooling takes time, the structure is complex and expensive, and the heat insulating material is difficult to remove.

<Means for solving the problems> The present invention was made to solve the above-mentioned conventional drawbacks, and it blocks heat and light and can be attached and detached to the inside of box pallets, containers, etc. of different shapes and sizes. In addition to being able to wrap around the
The purpose of this project is to provide a container lining insulation enclosure that is lightweight, thin, and durable, and can maintain cold and heat retention at an appropriate temperature for a long period of time. A heat insulating sheet is formed into an expanded shape that matches the lining shape and has binding means attached to each edge, and when installed inside the container, its corners are pressed and supported with tension poles. , which can be folded and stored when not in use.

<Example> Hereinafter, an example in which the container lining insulation envelope of the present invention is used in an aviation container will be described in detail based on the attached drawings.

1A and 1B are cross-sectional views of a heat insulating sheet forming a heat insulating envelope according to the present invention, FIGS. 2A and 2B are external and internal perspective views of a container showing an embodiment of the present invention, and FIG. 4 is a perspective view showing the heat insulating envelope before it is assembled into the container, and FIG. 5 is a front view of the tension pole according to the present invention. In the figure, a heat insulating sheet 1 is made by laminating an aluminum layer 3 on a plastic film or sheet 2 made of polyethylene or polyester, and a cloth layer 5 on the aluminum layer 3.
are bonded together via an adhesive 4 such as polyethylene film for bonding, and a soft synthetic resin foam layer 6 is bonded to the fabric layer 5 again via the adhesive 4, and the heat insulating sheet 1 is Depending on the application, it may be double or triple laminated as shown in Figure 1b, and flame-retardant reinforcing cloth made of nylon fiber or the like may be added to important parts as necessary. You can also do it.

The container 7 shown in FIG. 2 is, for example, an aviation container, and has a bulge on the side for loading onto the aircraft and for space reasons, and has a front opening/closing door 9 that opens upward or sideways. It is becoming more and more common.

FIG. 3 is a developed top view of the heat insulating envelope according to the present invention. The heat insulating envelope 10 is formed by cutting a heat insulating sheet and thermo-compressing or sewing the edges.

The heat insulating enclosure 10 includes a ceiling wall 11 attached to the inner ceiling of the container 7, and a ceiling wall 11 attached to the inner ceiling of the container 7.
Fold around the four sides of 1 12a, 12b, 12c, 12d
Left and right side wall portions 13, 14 integrally provided via
, a rear wall portion 15 , a front wall portion 16 , and a bottom portion 1 integrally provided on the right side wall portion 14 via a fold 17 .
It consists of 8. Moreover, the side wall part and the rear wall part 1
3, 14, 15 and the main parts of the bottom part 18 are attached with reinforcing cloth made of nylon fiber as a base material to prevent damage due to load resistance. In addition, the left side wall portion 1
3 has a fold 19 formed therein so as to be pasted along the bulge 8 of the container 7.

The left and right side walls 13, 14, the rear wall 15, and the front wall 16 have creases 12a at both end edges, respectively.
A fastener 20 such as an adhesive cloth (velvet type fastener) or a planar locking tape is installed so that the fasteners 20 are fixed to each other when bent from 12d to 12d. Further, the front wall portion 16 is provided with a heat insulating enclosure 1.
0 is assembled and attached to the container 7, an opening/closing part 16a having a predetermined width is attached via a fastener 21 in order to carry in and take out goods, and when the fastener 21 is removed, the opening/closing part 16a opens upward. It is now possible to jump up.

Further, a friction cloth 22 is attached to the corners where the folds 12a to 12d formed on the four circumferences of the ceiling wall portion 11 intersect. On the other hand, a non-slip reinforcing cloth 23 may be attached to the upper surface of the ceiling portion 11 at an appropriate position.

Note that an adhesive cloth 24 is attached to the edges of the left side wall portion 13, rear wall portion 15, opening/closing portion 16a, and bottom portion 18.
are affixed to three sides of the bottom portion 18 to prevent displacement after assembly.

On the other hand, FIG. 5 shows the tension pole 2 according to the present invention.
5, and there is a rod 2 below the cylinder part 26.
7 is screwed in, and there is a rod 28 at the top that can be moved up and down via a spring (not shown).
is installed. Therefore, by fixing the cylinder portion 26 and rotating the rod 27, the length can be expanded or contracted, and the overall length L of the tension pole 25 can be adjusted.

Here, 29 is a mark indicating the top and bottom of the tension pole 25, and determines the direction of the base end portions 30, 31 attached to the ends of the rods 27, 28.

Therefore, in order to attach the lining insulation enclosure 10 inside the container 7 using the insulation enclosure 10 and the tension poles 25 configured as described above,
With the opening/closing door 9 of the container 7 open, the heat insulating enclosure 10 is assembled as shown in FIG. 4. At this time, after closing the fasteners 20 at both ends of the left and right side walls 13 and 14, the rear wall 15, and the front wall 16, the fasteners 21 of the front wall 16 are opened to open the opening/closing part 1.
Open 6a.

Next, the heat insulating enclosure 10 is pushed inside the container 7, and while adjusting the overall position, the tension poles 25 are placed at the portions where they contact the corners of the container 7 from the inside, that is, the four corners of the ceiling wall. Press and support.

At this time, the tension pole 25 is adjusted in advance to be a little longer with the mark 29 facing upward, and the upper rod 28 is pushed in against the spring when attached.

Once the heat insulating enclosure 10 is installed, check the movement of the fastener 21 of the opening/closing part 16a and the opening/closing of the opening/closing door 9. Place the bottom part 18 on the bottom of the container 7, and then The side wall portion 13 is housed and the installation is completed.

Note that the folds of the lip pieces 15a and 16b provided on the rear wall 15 and the front wall 16 are different depending on the presence or absence of the shelf board 8' of the bulge 8 of the container 7, and the inner surface of the container 7 is It is molded appropriately according to the shape. That is, if there is no shelf board 8', fold each lip piece 15a, 16b along the diagonal fold line, and if there is a shelf board 8', fold each lip piece 15a, 16b.
16b is used by folding it along the fold line parallel to the ceiling wall portion 11.

<Effects of the invention> As explained in detail above, according to the container lining insulation enclosure according to the invention, the heat transmission coefficient [K
It has an excellent insulation performance of 0.88 [Kcal/ ^m2・hr・℃], and incorporates an easily detachable and easy-to-assemble heat insulating enclosure inside containers that need to maintain the appropriate temperature for long periods of time. It has excellent cold and heat retention effects.

Furthermore, since the heat insulating envelope incorporated in the container is foldable, it is easy to store and transport, and it is lightweight at 1.1 kg/m ² , so it is suitable for aircraft cargo without being a burden.

Furthermore, it is easy to assemble, easy to adjust dimensions, and can be applied to containers of various sizes, thereby streamlining the logistics system.
