Description

本発明は、断熱ボックスに関する。 The present invention relates to an insulating box.

従来、断熱材として樹脂(ウレタン)を用いた断熱ボックスが知られている(例えば、特許文献1参照)。 2. Description of the Related Art Conventionally, a heat insulating box using a resin (urethane) as a heat insulating material is known (see Patent Document 1, for example).

実開平1-73175号公報Japanese Utility Model Laid-Open No. 1-73175

しかし、特許文献1記載の断熱ボックスは、樹脂製断熱材の表面に配設される板が、(伝熱性の高い)金属から成るので、断熱ボックス全体としての断熱性が低いという問題がある。特に、金属板相互の当接部(ボックスの辺部近傍)に於て、熱が逃げるという問題があった。そこで、本発明は、断熱性が高く確実に断熱することができる断熱ボックスを提供することを目的とする。 However, the heat insulating box described in Patent Document 1 has a problem that the heat insulating property of the heat insulating box as a whole is low because the plate arranged on the surface of the resin heat insulating material is made of metal (having high heat conductivity). In particular, there is a problem that heat escapes at the contact portions between the metal plates (near the side portions of the box). SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a heat insulating box that has high heat insulating properties and can be reliably insulated.

本発明に係る断熱ボックスは、上シート部と下シート部と中間連結部とから成る断熱段ボール構造のボードを折曲げた扁平状中空箱体と、該中空箱体の内部に注入して発泡充填された発泡樹脂から成るパネル体を、備え、5枚の上記パネル体を相互に連結した前方開口状の断熱ボックス本体と、上記断熱ボックス本体の前方開口部に開閉自在として枢着された一枚の上記パネル体から成る断熱扉と、をもって、全体を密封開閉自在な箱型に組み立てた断熱ボックスであって、上記断熱ボックス本体を形成する5枚の上記パネル体が、隣り合うパネル体に連結するための連結用突片を有し、該連結用突片は、上記ボードの一端縁をもって、形成されているものである。 The heat insulating box according to the present invention comprises a flat hollow box body formed by folding a board having a heat insulating corrugated board structure composed of an upper sheet portion, a lower sheet portion, and an intermediate connecting portion, and foam filling by injecting foam filling into the inside of the hollow box body. a front- opening heat - insulating box body in which the five panel bodies are interconnected; A heat insulating box assembled into a box shape that can be opened and closed in a sealed manner with a heat insulating door made up of two panel bodies, wherein the five panel bodies forming the heat insulating box main body are arranged adjacent to each other. It has a connecting protrusion for connecting to the flannel body, and the connecting protrusion is formed with one end edge of the board .

本発明の断熱ボックスによれば、断熱性が高く確実に断熱することができる。 According to the heat insulation box of the present invention, heat insulation is high and heat insulation can be reliably performed.

以下、図示の実施の形態に基づいて本発明を詳説する。
図1~4は、本発明の実施の一形態を示す。この断熱ボックスは、内部に、例えば、食品、医療品等を入れて、外部との熱の伝達を遮断するために用いられる。複数枚のパネル体1を相互に連結した前方開口状の断熱ボックス本体2と、一枚のパネル体1から成り断熱ボックス本体2に開閉自在に枢着された断熱扉3と、をもって、全体を密封開閉自在な箱型に組み立てられる。図1(B)に於て、4は枢着部材を示し、断熱ボックス全体の表面から可能な限り突出部位の無い箱型とするために、1mm~4mm程度の厚さT4 を有する(軟質)プラスチック板から成り、かつ、折り曲げ用の三角溝15を有する。また、5はロック部材を示す。
BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below based on the illustrated embodiments.
1-4 show an embodiment of the invention. This heat insulating box is used to contain, for example, food, medical supplies, etc., and block heat transfer to the outside. A front-opening heat insulating box body 2 in which a plurality of panel bodies 1 are connected to each other, and a heat insulating door 3 composed of one panel body 1 and pivotally attached to the heat insulating box body 2 so as to be opened and closed. Assembled in a sealed box shape that can be freely opened and closed. In FIG. 1(B), reference numeral 4 denotes a pivot member, which has a thickness T4 of about 1 mm to 4 mm (soft ) consists of a plastic plate and has triangular grooves 15 for folding. Further, 5 indicates a locking member.

パネル体1は、図7・図8に示すように、プラスチックボード6(図9参照)を折曲げた扁平状中空箱体7と、中空箱体7の内部に注入して発泡充填された発泡樹脂8から成る。プラスチックボード6は、例えば、ポリウレフィン等から成る。発泡樹脂8は、例えば、発泡ウレタンである。 As shown in FIGS. 7 and 8, the panel body 1 includes a flat hollow box 7 formed by bending a plastic board 6 (see FIG. 9), and a foamed material injected into the hollow box 7 and filled with foam. It consists of resin 8 . The plastic board 6 is made of, for example, polyolefin or the like. The foamed resin 8 is, for example, urethane foam.

パネル体1の厚さ寸法Tを、30mm≦T≦50mmに設定する。厚さ寸法Tが、上記範囲にある場合、高い断熱性が得られるとともに、パネル体1の強度が大きい。厚さ寸法Tが、T<30mmの場合、適切な断熱性が得られない虞れがあるとともに、パネル体1の強度が不足する。厚さ寸法Tが、50mm<Tの場合、厚過ぎて材料が無駄である。 The thickness dimension T of the panel body 1 is set to 30 mm≤T≤50 mm. When the thickness dimension T is within the above range, high heat insulation is obtained and the strength of the panel body 1 is large. If the thickness dimension T is T<30 mm, there is a possibility that an appropriate heat insulating property cannot be obtained, and the strength of the panel body 1 is insufficient. If the thickness dimension T is 50 mm<T, it is too thick and the material is wasted.

ボックス本体2を形成する5枚のパネル体1の一部内至全部が、隣り合うパネル体1に連結するための連結用突片9を有する。(ブラインド)リベット10にて固着する。 All of the five panel bodies 1 forming the box body 2 have connecting protrusions 9 for connecting to the adjacent panel bodies 1 . (Blinds) Secure with rivets 10.

図10に示すように、プラスチックボード6は、上シート部11と下シート部12と中間連結部13とから成る断熱段ボール構造である。段ボール構造は、空隙部Eを有するので、断熱性が高い。 As shown in FIG. 10, the plastic board 6 has an insulating corrugated board structure comprising an upper sheet portion 11, a lower sheet portion 12 and an intermediate connecting portion 13. As shown in FIG. Since the corrugated cardboard structure has voids E, it has high heat insulation.

プラスチックボード6は、例えば、「プラパール」(川上産業株式会社の登録商標)から成る。「プラパール」は、図10(A)(B)に示すように、上シート部11と下シート部12と、複数の凸部14を有する中間連結部13とを、重ね合わせて一体化した構造である。 The plastic board 6 is made of, for example, "PLAPEARL" (registered trademark of Kawakami Sangyo Co., Ltd.). As shown in FIGS. 10(A) and 10(B), "Plapearl" has a structure in which an upper sheet portion 11, a lower sheet portion 12, and an intermediate connecting portion 13 having a plurality of convex portions 14 are superimposed and integrated. is.

図11は、プラスチックボード6の他例を示す。上シート部11と下シート部12と波型の中間連結部13とが、一体成型されている。 FIG. 11 shows another example of the plastic board 6. FIG. The upper sheet portion 11, the lower sheet portion 12, and the corrugated intermediate connecting portion 13 are integrally molded.

図7(B)に示すように、パネル体1とパネル体1との結合部位に於て、(従来のプラスチック薄板のみからなる場合に比べて、)本発明では断熱性の高いプラスチックボード6を用いたので、内部の熱が矢印H方向へ逃げること、又は、外部から熱が矢印Hと反対方向に侵入することを、有効に阻止できる。 As shown in FIG. 7(B), a plastic board 6 having high heat insulation (compared to the conventional thin plastic plate) is used at the joint between the panel bodies 1 in the present invention. Since it is used, it is possible to effectively prevent internal heat from escaping in the direction of arrow H, or external heat from entering in the direction opposite to arrow H.

なお、本発明は、設計変更可能であって、例えば、リベット10によるパネル体1の結合を、接着剤等で行うことも、自由である。 It should be noted that the present invention can be modified in design, and for example, it is also possible to freely connect the panel body 1 with the rivets 10 with an adhesive or the like.

以上のように、本発明は、プラスチックボード6を折曲げた扁平状中空箱体7と、該中空箱体7の内部に注入して発泡充填された発泡樹脂8から成るパネル体1を有し、複数枚の上記パネル体1を相互に連結した前方開口状の断熱ボックス本体2と、一枚の上記パネル体1から成り上記断熱ボックス本体2に開閉自在に枢着された断熱扉3と、をもって、全体を密封開閉自在な箱型に組み立てた断熱ボックスであって、上記プラスチックボード6が、上シート部11と下シート部12と中間連結部13とから成る断熱段ボール構造であるので、断熱性が高く確実に断熱することができる。また、軽量でありながら、強度が大きい。さらに、中空箱体7の内部に発泡樹脂8を注入して発泡充填することにより、パネル体1を容易に製造することができる。 As described above, the present invention has a flat hollow box 7 formed by bending a plastic board 6, and a panel body 1 comprising a foamed resin 8 injected into the inside of the hollow box 7 and filled with foam. a front-opening heat insulation box body 2 in which a plurality of the panel bodies 1 are connected to each other; a heat insulation door 3 composed of one panel body 1 and pivotally attached to the heat insulation box body 2 so as to be openable and closable; In this heat insulating box, the whole is assembled into a box shape that can be freely closed and closed, and the plastic board 6 has a heat insulating cardboard structure consisting of an upper sheet portion 11, a lower sheet portion 12, and an intermediate connecting portion 13, so that heat insulation is achieved. It is highly durable and can insulate reliably. In addition, it has a high strength while being lightweight. Furthermore, the panel body 1 can be easily manufactured by injecting the foamed resin 8 into the inside of the hollow box body 7 and filling it with foam.

また、上記ボックス本体2を形成する5枚の上記パネル体1の一部内至全部が、隣り合う上記パネル体1に連結するための連結用突片9を有するので、密封性が高く、従って、断熱性が良い。また、隣り合うパネル体1相互を、容易に連結することができる。 In addition, since all of the five panel bodies 1 forming the box body 2 have the connecting projecting pieces 9 for connecting to the adjacent panel bodies 1, the sealing performance is high. Good heat insulation. Also, adjacent panel bodies 1 can be easily connected to each other.
