Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer container functioning as a heat insulating or protecting material for a hot water storage tank, a cold storage tank, or the like, and to a heat storage container provided with heat insulation and protection measures.

[0002]

2. Description of the Related Art Conventionally, for example, in heat insulation and protection of a hot water storage tank, provision of a heat insulating material for preventing heat from flowing to the outside and installation of an outer container for protecting the hot water storage tank from the surrounding environment are separately performed. Have been done.

[0003]

However, under the employment of such conventional means, efficiency is low in terms of mass productivity and workability, and it has been difficult to reduce equipment costs.

[0004] The present invention has been made in view of the above circumstances, and has as its object to provide an outer container and a heat storage container having good mass productivity and workability.

[0005]

Means for Solving the Problems An exterior container according to the present invention made to solve the above-mentioned problem is constituted by a plurality of exterior members having a heat insulating layer made of a foamed resin as an inner layer immediately below a coating layer, The heat storage container according to the present invention made to solve the above-described problem is characterized in that the inner surface of the integrally assembled exterior member forms the appearance of the heat-insulated container. It is characterized by comprising an exterior member having a layer, and a container body inserted and held inside the exterior member material.

[0006] The outer container is a container capable of protecting the heat-insulated container housed therein from the outdoor environment. What is a coating layer?
A resin layer formed to a substantially uniform thickness by various coating methods such as gel coating.The gel coating layer is formed by forming a resin coating layer on the mold surface by hand lay-up method, spray-up method, etc. Say that layer. The inner layer immediately below the coating film refers to a layer that is in close contact with the inner surface of the coating film, and in some cases, another layer is formed inside the inner layer, that is, the heat insulating layer. The exterior member is
These are a part or all of an outer container in which these various layers are integrally laminated. When the inner surface of the assembled outer member forms the appearance of the insulated container, the inner surface of the outer member is formed into a shape that is in close contact with or in close proximity to most of the outer surface of the insulated container. It means that a concave portion having a rough silhouette is formed. The container body is a container inserted and held inside the exterior member as the heat-insulated container, and the insert holding refers to a state in which the inner surface of a single exterior member is held so as to wrap the container body. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an outer container according to the present invention will be described below with reference to the drawings. The exterior container shown in FIG. 1 includes a heat insulating layer 2 made of a urethane synthetic resin as a foamed resin inside a coating layer 1 (hereinafter, referred to as a gel coat layer 1) made of an acrylic synthetic resin or a polyester synthetic resin. It is composed of a pair (plural) of exterior members 3 and 3,
The exterior members 3 and 3 are each formed in a split shape on the inner surface of a container to be insulated (not shown).

[0008] As shown in FIG.
As shown in (a), the synthetic resin 5 serving as the gel coat layer is uniformly sprayed on the molding surface of the lower mold 4 with a spray gun, and the upper mold 6 closes the mold. Then, as shown in (b), the urethane synthetic resin 8 is injected into the molds 4 and 6 from the injection hole 7 and sufficiently foamed and solidified to take out the product 9 as shown in (c). The exterior member 3 which is shaped as such is formed into a cylinder with a highly weather-resistant adhesive or adhesive tape as a set of two.

FIG. 3 shows a case in which insert molding is performed to load the container body 14 as a container to be insulated into the exterior member 13. First, the synthetic resin to be the gel coat layer is uniformly sprayed on the molding surfaces of the upper mold 15 and the lower mold 16 by using a spray gun to form the coating layer 11 as shown in FIG. Next, as shown in (b), the container main body 14 is fixed to the hollow portion 18 on the inner surface of the mold with the nest 19 and the holding material 20, and the upper and lower dies 15,
After the combination of 16, the urethane synthetic resin 21 is injected from the injection hole 17 as shown in (c) to sufficiently foam and solidify as shown in (d), and the molds 15 and 16 are removed as shown in (e) to take out the product 22. By removing the nest 19 from the product 22 as shown in (f), a heat storage container having substantially the same shape as that of FIG. 1 and having the heat-insulated container inserted therein is formed.

The above outer container and heat storage container are assumed to be installed outdoors as they are because of the high adhesion between the gel coat layers 1 and 11 and the heat insulating layers 2 and 12 and the high weather resistance of the epoxy resin film as the gel coat layers 1 and 11. Can suitably function as an exterior material without being extremely deteriorated over a long period of time. Moreover, it can be obtained through a relatively simple manufacturing method as described above. Therefore, since the step of painting can be omitted, mass production is high and the production cost can be reduced, and the heat-insulating layers 2 and 1 made of foamed resin formed inside.
2, if the heat insulating layers 2 and 12 are formed so as to be in close contact with the heat-insulated container (container body 14),
The heat-insulated container (container main body 14) to be included can also be favorably held. In addition, if the molding dies of the exterior members 3 and 13 are devised, a silhouette having a high design property can be provided, and the beauty of the outdoors is not spoiled.

[0011]

As described above, the use of the outer container and the heat storage container according to the present invention improves the efficiency in terms of mass productivity and workability, facilitates reduction of equipment costs, and improves the appearance of the installation location. Consideration to prevent damage is also facilitated.
