ものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat insulator used in heat insulating boxes for refrigerators, freezers, show cases, prefabricated refrigerators, and the like.
従来例の構成とその問題点
第１図から第３図は従来のプレハブ冷蔵庫等に
用いる断熱体を示しており以下にこの従来例の構
成につて説明する。Structure of the conventional example and its problems FIGS. 1 to 3 show a heat insulator used in a conventional prefabricated refrigerator, etc., and the structure of this conventional example will be explained below.

る。 In the figure, 1 is a heat insulating board. Further, 2 is an inner bag having air permeability, and 3 is a powder 3 such as perlite filled in the inner bag 2. 4 is a bag made of metal-plastic laminate film, etc.
After inserting the inner bag 2 filled with the powder 3 and reducing the pressure inside to 0.1 Torr or less, the opening of the bag 4 is sealed by heat sealing to form the above-mentioned heat insulating board 1. Reference numeral 5 denotes a peripheral edge portion of the heat insulating plate 1, which is formed by welding the end portion when the bag 4 is formed. Reference numeral 6 denotes a heat insulating body for a prefabricated refrigerator, etc., in which the heat insulating board 1 is arranged between an inner plate 7 made of synthetic resin or the like and an outer plate 8 made of metal, in contact with the outer plate 8, and a foamed heat insulator made of hard polyurethane foam or the like is arranged. A material 9 is integrally foamed between both plates 7 and 8.
このような断熱板１の製造にあたり、中袋２に
粉末３を入れて平板状にした後、外袋４に挿入す

入しにくかつた。また、袋４内部を減圧する際、
排気抵抗を減少し、排気時間を短縮する為、袋４
と内袋２の間に排気通路１０を設ける必要があつ
た。以上の理由から袋４を内袋２に比べ十分大き
くしなければならなかつた。 In manufacturing such a heat insulating board 1, after putting the powder 3 into the inner bag 2 and making it into a flat plate shape, when inserting it into the outer bag 4, it was difficult to insert the bag 4 unless it was considerably larger than the inner bag 2. . Also, when reducing the pressure inside the bag 4,
Bag 4 is used to reduce exhaust resistance and shorten exhaust time.
It was necessary to provide an exhaust passage 10 between the inner bag 2 and the inner bag 2. For the above reasons, the bag 4 had to be made sufficiently larger than the inner bag 2.
しかしながら、上記従来例においては、袋４を
内袋２に比べ十分大きくすると周縁部５が長くな

断熱体６の断熱性能を劣化させる問題点があつ
た。 However, in the above conventional example, if the bag 4 is made sufficiently larger than the inner bag 2, the peripheral edge 5 becomes long, and when the foam insulation material 9 is integrally foamed, the flow of the foam insulation material 9 is obstructed and voids 9a are generated. In addition, air may become trapped between the long peripheral portion 5 and the outer panel 8, causing an unfilled portion 9b of the foam insulation material 9.
There was a problem that the heat insulating performance of the heat insulating body 6 deteriorated.

去するものである。Structure of the Invention In order to achieve the above object, the present invention bends the peripheral edge along a heat insulating plate, fixes the end of the peripheral edge to the heat insulating plate using a fixing member such as tape or adhesive, and This is to be brought into close contact with the heat insulating board. This eliminates the negative influence of the peripheral edge, which inhibits the flow of the polyurethane foam and forms air pockets, causing voids and unfilled areas with urethane.
実施例の説明
以下に本発明の一実施例の構成について、第４
図から第５図を参考に説明するが、従来と同一構
成については同一番号を付して、その詳細な説明
を省略する。DESCRIPTION OF EMBODIMENTS The configuration of one embodiment of the present invention will be explained below in the fourth section.
The description will be made with reference to FIGS. 5 to 5, and the same components as the conventional ones are given the same numbers and detailed explanations thereof will be omitted.
図において、１１はプラスチツク等から成る粘
着性のテープ等の固定部材で、周縁部５は断熱板
１の同一面上に密着するように固定部材１１で固
定されている。 In the figure, reference numeral 11 denotes a fixing member such as adhesive tape made of plastic or the like, and the peripheral edge 5 is fixed by the fixing member 11 so as to be in close contact with the same surface of the heat insulating plate 1.
そして、外板８に断熱板１の固定部材１１のな
い側の面をホツトメルト等の接着材を介して取付
け、外板８と内板７の間に発泡断熱材９を充填す
る。 Then, the surface of the heat insulating board 1 on the side without the fixing member 11 is attached to the outer panel 8 via an adhesive such as hot melt, and a foamed heat insulating material 9 is filled between the outer panel 8 and the inner panel 7.

部分が発生することがなく断熱性能良好な断熱体
を得られるものである。 Therefore, the peripheral edge does not impede the flow of the foam insulation material such as rigid polyurethane foam, so there is no formation of air pockets, voids, or unfilled areas with urethane, resulting in an insulation with good insulation performance. It is something that can be obtained.
なお本発明の実施例では、周縁部を断熱板に固
定するのに固定部材として粘着性のテープを用い
たが、周縁部が断熱板に密着する部分に接着剤ま
たはホツトメルトを塗布して周縁部と断熱板を接
着してもよい。 In the embodiment of the present invention, an adhesive tape was used as a fixing member to fix the peripheral edge to the heat insulating board, but adhesive or hot melt was applied to the part where the peripheral edge adhered to the heat insulating board. You can also glue the insulation board.

熱体を得られるという利点がある。Effects of the Invention The present invention has the above-mentioned configuration, and unlike conventional methods, the peripheral edge of the heat insulating plate does not obstruct the flow of foamed heat insulating material such as rigid polyurethane foam or form air traps. Therefore, there is an advantage that a heat insulating body with good heat insulation performance can be obtained.
