Description

The present invention relates to a heat insulation / cooling case for keeping water / cold water for drinking water, food, and the like.

There are cases that use cans and bottles of alcohol and soft drinks to last longer in the cold state, such as those using heat insulating materials such as plastic, and metal-made cold storage cases with a thermos structure.
In addition, a cylindrical one-stage cardboard is used that protects the hand from the heat of a paper coffee cup and slightly contributes to heat retention.

However, a vacuum-structured metal product such as a thermos has good heat insulation and cold insulation performance, but also takes up storage space and has problems in terms of weight and cost. Plastics are inferior in performance to metal, but are lightweight. However, there is a problem that recycling is difficult. The main purpose of the cylindrical cardboard is to protect the hands from the heat of the coffee cup, which contributes to heat retention but does not cover the bottom of the cup and does not cover the bottom. It is insufficient as a function.

The present invention has been made based on such a background, and in order to suppress the temperature change of products such as cans and bottles (warming / cooling), simple, low-cost, and easily recyclable materials were used. The purpose is to provide heat insulation and cold insulation cases.

In order to solve the above-mentioned problems, the heat insulation / cold insulation case of the present invention is plate-like at the time of deployment, and covers a container so as to be in close contact with the container at the time of use, and a side surface portion made of corrugated cardboard having a heat insulating action
Among the two long sides of the plate-shaped side surface portion, a plurality of surface portions provided on the bottom side of the container, which can be bent toward the bottom side at the boundary with the side surface portion, from a corrugated cardboard having a heat insulating action A plurality of face portions,
And a joining means that is provided in the vicinity of two short sides of the plate-like side surface portion and adheres to each other when the side surface portion is wound into a tubular shape.

The heat-retaining / cooling case is a single cardboard and is used so that its step side is in close contact with the container.

The said joining means consists of a weak adhesive material, and can bond the said short sides, when the said side part is wound around a container at the time of use.

The joining means is a surface portion provided above or below the long side of the portion to be joined of the side surface portion, and is bent so as to wrap the inside of the overlapping surface portion when the side surface portion is wound around the container during use. The short sides can be joined to each other according to the size of the container.

Instead of the plurality of surface portions forming the bottom surface, a bottom surface portion may be formed by a heat-insulating surface portion that can be folded at one time at the boundary with the side surface portion by inserting a crease, a perforation, and a cut portion. It is possible to do.

According to the present invention, it is possible to provide a heat insulating / cooling case that is inexpensive, lightweight, and friendly to the environment.

It is the perspective view which showed the state which mounts | wears a container with the heat insulation / cold insulation case shown in FIG. It is an expanded view of the heat insulation / cold insulation case which concerns on another embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a basic shape of a heat insulating / cooling case 1 according to an embodiment of the present invention, which can be obtained by shaping a flat plate material made of single cardboard. A corrugated cardboard as a material can be appropriately used with a thickness of several millimeters, but here, a single corrugated cardboard having a thickness of about 3 mm is used. The length indicated by L in the figure is set to an extent in which its own thickness is added to the peripheral length of a container (for example, a can of soft drinks) to be kept warm.

In the basic shape of FIG. 1, a side surface portion 2 having a heat insulating effect so as to surround a container to be kept warm and a surface portion 4 is provided via a crease 3. This surface part 4 provides the heat insulation effect between a container and what mounts this. Moreover, the surface part 5 and the surface part 6 as a margin are provided in the left-right area of the side part 2. Adhesive paste is applied to the margin and bonded to the surface portion 6 in advance and used in a ring shape, or it can be joined at the time of use by applying a weak adhesive paste so as to be fastened to the surface portion 6 at the time of use. it can. In either case, it can be stored in a flat state.

As shown in FIG. 2, the container 10 generally has a diameter of about 63 mm, which is commonly used for can products such as soft drinks, and the side surface 11 and the bottom surface 12 of the side surface portion 2 and the surface portion 4 of the heat insulation / cooling case 1 are arranged. To be enclosed by. If the size of the container 12 is changed to some extent, extra margin 5 is provided so that it can be sufficiently enclosed, and if weakly adhesive glue is applied, the size of the container can be reduced by holding it in use. Even if it is slightly different, it is possible to enclose without problems.

FIG. 3 is a perspective view showing a state where the can is actually enclosed. The step side of the single cardboard is in contact with the can so that the contact area between the present invention and the can is minimized. By carrying out like this, the air layer between steps acts as a heat insulation layer. FIG. 4 is a perspective view of the state of FIG. 3 viewed from the bottom side. By bending the surface portion 4 at the crease 3 toward the bottom surface 12, the surface portion 4 acts as a heat insulating layer for the bottom surface 12 of the can.

Further, as shown in FIG. 5, it is also possible to insert the cardboard tab portion 8 into the opening portion 7 in place of the glue so as to be joined.

FIG. 6 is a development view of the heat insulating / cooling case 20 having a shape in which the surface portion 21 is added to the basic shape shown in FIG. By doing so, when the container is wound into a tubular shape, the surface portion 21 is folded to the container side of the overlapping surface portions 5 and 6 as shown in FIG. 7 (A), and the container is inserted as shown in FIG. 7 (B). By joining with pressure, it can be used as a heat insulation and cold insulation case, and there is no need for gluing.

Further, instead of the surface portion 4 corresponding to the bottom surface in the heat insulating / cooling case shown in FIGS. 1 and 6, the surface portion is formed by inserting a perforation 23, a fold line 24, and a cut portion 25 in the shape shown in FIG. Instead of bending the four pieces one by one, it is also possible to fold them along the crease 3 and the cut part 25 that are boundaries with the side surface part 2 and then enclose the container. The perforations are for easy folding. Since the front end of the surface 4 is bent toward the center of the bottom of the can when the container is enclosed at the same time, the fold line 24 between the perforations 23 rises to the bottom of the can in the shape of a mountain ridge. This is simpler than folding the individual surface portions 4 of FIG.

The heat insulating / cooling case of this embodiment can be easily manufactured with a plate material such as corrugated cardboard and can be stored in a plate-like state before use. Variations in the dimensions of the container used can be tolerated to some extent, and can be used as a heat insulating / cooling case with sufficient heat insulation. Further, by depositing aluminum or the like on the cardboard, the heat insulating / cooling effect can be further enhanced. In this embodiment, a single cardboard is used. However, any cardboard having a similar function and shape (for example, paper glassine) can be used as a heat insulating / cooling case.
