Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly-type cold-keeping / heat-retaining box, and more particularly to an assembling-type cool-keeping / heat-retaining box used for delivery and storage of products that need to be kept cold or warm, such as medicines and foods.

[0002]

2. Description of the Related Art For example, various perishable foods, in-flight meals for airplanes, and the like need to be kept cold or warm, so that it is necessary to use a container having a function of keeping warm during cold transportation.

As a conventional transport container for keeping cold and warm, a prefabricated type box which is assembled by connecting a styrofoam carrying box or a heat insulating panel is used. The returnable box refers to a box that is repeatedly used without being disassembled after it is assembled once.

[0004]

By the way, the former Styrofoam carrying box does not change in bulk even during empty transportation, resulting in high transportation costs and difficulty in disposal after the end of its useful life. There is.

On the other hand, the latter prefabricated box has an advantage that it can be reduced in bulk during empty transportation, but has a problem that it requires much time and labor for assembling and disassembling. The present invention has been made in view of such circumstances, and an object of the present invention is to provide an assembly-type cold-keeping / heat-retaining box that can be easily assembled during use, can be easily disassembled after use, and is not bulky even after disassembly.

[0006]

Therefore, the present invention adopts the following configuration in order to solve the above problems.

<< First Assembly-Type Cooling / Heat Keeping Box of the Present Invention >> The first assembling-type cold-keeping / keeping box of the present invention is a box assembled from six plate-like heat insulating members. Is provided with a coupling portion that detachably couples the heat insulating members.

<< Second Assembly Type Cooling / Heat Keeping Box of the Present Invention >> A second assembling type cold keeping / keeping box of the present invention is a top plate,
It is a box in which a bottom plate, a back plate, a front plate, a first side plate, and a second side plate are formed of heat insulating members, and a connecting portion for detachably connecting the heat insulating members is provided on the peripheral portion of each heat insulating member. There is. Of the above-mentioned connecting portions, the connecting portion for connecting the top plate and the front plate and the connecting portion for connecting the back plate and the bottom plate are configured to be bendable.

The top plate and the front plate, and the back plate and the bottom plate may not be separable from each other. In addition, in the second assembled cold-keeping / warming box, the connecting portion between the top plate and the front plate or the connecting portion between the back plate and the bottom plate is connected to at least the upper surface and the lower surface of the peripheral portion of the other heat insulating member. You may do it. For example, a hook-and-loop fastener such as Velcro (registered trademark) or Velcro Magic Fastener (registered trademark) can be used as the connecting portion. Here, taking as an example the connecting portion between the top plate and the front plate, surface fasteners are attached to the upper and lower surfaces of the peripheral portion of the top plate. At the same time, a sheet-like flexible member protruding upward is provided on the upper end of the front plate, and a surface fastener is attached to the back surface of this flexible member. However, the lower end portion of the surface fastener is not fixed to the flexible member but can be bent independently of the flexible member. Then, when connecting the top plate and the front plate, the upper end of the flexible member is bent to combine the surface fastener on the back surface with the surface fastener on the top surface of the top plate, and the surface fastener on the back surface of the flexible member. Bend the lower end of the and join it to the hook-and-loop fastener on the bottom of the top plate. At this time, the surface fastener on the front plate side forms a U-shaped cross section and holds the peripheral edge of the top plate. With this, the top plate is joined at the two surfaces of the upper face and the lower face, and the joining strength between the top plate and the front plate can be improved. Furthermore, if a surface fastener is attached to the side surface portion of the peripheral portion of the top plate, the top plate and the front plate will be joined on three sides, and the joining strength can be further improved. When the top plate and the front plate cannot be separated from each other, a double-sided tape or an adhesive can be used instead of the surface fastener.

Further, in the second assembled cold-keeping / warming box, the front plate may be formed by connecting at least two plate-like heat insulating members so as to be bendable. Also,
In the second prefabricated cool / warm box, the first side plate,
The second side plate or the back plate should have at least one holding portion for detachably fixing the first side plate, the second side plate, or the back plate to the column installed upright. You may Here, as the holding unit, for example,
Two strip-shaped surface fasteners can be used. That is, one end of each of the two surface fasteners is fixed to the heat insulating member. Then, at the time of use, the column or the like is sandwiched between the two surface fasteners, and the other ends thereof are joined together.

Further, in the first or second assembled cold-keeping / warming box, the heat insulating member is a metal foamed polyethylene terephthalate film, a polyethylene film, a foamed polyethylene sheet, and a polyethylene cloth on both sides of an elastic foam material. You may make it use the thing provided with the reflective layer which consists of.

In the first or second assembled cold-keeping / warming box, the foam material may be formed of polystyrene foam, polyethylene foam, polypropylene polypropylene, or urethane foam alone or in combination.

The operation of the present invention will be described below. The first assembly-type cold-keeping / warming box of the present invention is assembled in a box shape by joining six plate-like heat insulating members at the joining portion. In addition, it is dismantled by removing the joint portion.

Further, the second assembling type cold-keeping / warming box of the present invention is assembled in the following procedure at the time of use. Procedure 1) Join the back plate and the bottom plate.

Procedure 2) The back plate and the bottom plate are bent at a right angle at the connecting portion so that the back plate stands upright from the bottom plate. Here, the back plate may be manually supported, but if it stands upright on the outer wall or the like, it will not be necessary to manually support it.

Step 3) Join the first side plate and the second side plate to the back plate. Step 4) Join the top plate to the back plate, the first side plate, and the second side plate. Step 5) Join the front plate to the top plate. The front plate and the top plate may be joined together before step 4).

Here, the article is preferably stored before attaching the front plate. In addition, when storing or taking out the article after completion, if the user pulls the lower end of the front plate toward you, the front plate rotates about the joint with the top plate as an axis,
The front plate is opened.

On the other hand, disassembly is carried out in the reverse order of assembly. Incidentally, the front plate and the top plate, and the back plate and the bottom plate can be made bulky by bending the joints without removing the joints.

Particularly, in the second assembling type cool / heat-retaining box, a U-shaped grip portion is provided at the connecting portion between the top plate and the front plate and the connecting portion between the back plate and the bottom plate, so that The front plate, the back plate, and the bottom plate are firmly connected to each other, and there is no fear that they will separate from each other even when repeatedly bent.

Further, by providing the first side plate, the second side plate, or the back plate with the holding portion, the first side plate, the second side plate, or the back plate can be fixed to the column. The stability during assembling work and dismantling work, or the stability after assembling will increase.

Further, by molding the heat insulating member with a resin foam material, the weight of the entire box can be reduced.
