Description

本発明は、主に保冷あるいは保温を要する食材や食品等の各種物品の保管、運搬に使用される断熱容器に関するものである。   The present invention relates to a heat insulating container used mainly for storage and transportation of various articles such as foods and foods that need to be kept cold or warm.

例えば、生活協同組合(以下、生協という)の冷蔵、冷凍食品や食材等の保冷、或いは保温を要する食品等の宅配、運搬用の物流用の容器としては、合成樹脂発泡体を主材とする蓋付きのボックス形式の断熱容器が一般に使用されており、通常、前記食材等の内容物とともに、保冷用のドライアイスや蓄冷材或いは保温用の蓄熱材等の機能保持材を収容して使用される。   For example, as a container for refrigeration of living cooperatives (hereinafter referred to as co-ops), refrigeration of frozen foods and foods, home delivery of foods that require heat insulation, and logistics for transportation, the main material is synthetic resin foam. A box-type insulated container with a lid is generally used, and usually contains the contents such as the above-mentioned foodstuffs and contains function holding materials such as dry ice for cold insulation, cold storage materials or heat storage materials for heat insulation. The

前記の生協の食材等の宅配用の容器では、前記機能保持材を収納するための収納部を設けずに、収納される食材等の内容物の側面や上面の容器内面との間に機能保持材を配置して収納する単純な形式が殆どであった。そのため、容器内部には内容物の周囲に多くの無駄なスペースが生じることになって、それだけ収納部空間の容積に対する収納効率が低くなるものであった。   In the container for home delivery such as the food of the co-op, the function is maintained between the side of the contents such as the stored food and the inner surface of the container without providing a storage portion for storing the functional holding material. Most of the simple forms were arranged and stored. Therefore, a lot of useless space is generated around the contents inside the container, and the storage efficiency with respect to the volume of the storage space is lowered accordingly.

前記の問題を解消するために、側壁内面に機能保持材を収納するための凹部を設けておくことが考えられるが、この場合、側壁の前記凹部の個所においても、必要最低量の肉厚を確保する必要があり、それだけ容器外形が大きくなり、特にコーナー部においては肉厚のボリュームが大きくなり、不経済である。   In order to solve the above problem, it is conceivable to provide a recess for storing the function-retaining material on the inner surface of the side wall, but in this case, the necessary minimum amount of wall thickness is also provided at the position of the recess on the side wall. The outer shape of the container needs to be secured, and the volume of the wall is particularly large at the corner, which is uneconomical.

また、かかる断熱容器には、運搬等における積み卸し等の取り扱い作業のための取っ手等の手掛け部が、側壁外面における幅方向の中央部に凹設して設けられているのが一般的である(特許文献1及び2)。   In addition, such a heat insulating container is generally provided with a handle portion such as a handle for handling operations such as unloading in transportation, etc., being recessed in the central portion in the width direction on the outer surface of the side wall. (Patent Documents 1 and 2).

しかし、前記のように側壁外面に凹設による手掛け部を設ける場合は、従来の側壁の厚みのままでは、該手掛け部の部分で肉薄になって断熱効果や強度が低下することになるので、通常は、前記手掛け部を凹設する部分の側壁の厚みを、例えば容器内面側に、あるいは外面側に大きくする必要があり、そのため、容器外形の割には収納部空間としての内容積が小さくなったり、あるいは容器外形が大きくなり、容器の収納効率や輸送効率を低下させる一因となっていた。   However, as described above, when providing a handle by recessing on the outer surface of the side wall, with the thickness of the conventional side wall, it becomes thin at the part of the handle and the heat insulation effect and strength are reduced. Usually, it is necessary to increase the thickness of the side wall of the portion where the handle portion is recessed, for example, on the inner surface side of the container or on the outer surface side. Therefore, the inner volume as the storage space is small for the outer shape of the container. Or the outer shape of the container is increased, which is one of the causes for reducing the container storage efficiency and the transport efficiency.

特に、前記のように側壁内面に機能保持材を収納するための凹部を設けたものにおいては、前記のような手掛け部を側壁外面に設けた場合、所定の容積を確保しようとすれば、容器外形がさらに大きくなり、積載効率がさらに悪化させるものであった。

In particular, in the case where the concave portion for storing the function-holding material is provided on the inner surface of the side wall as described above, if the handle portion as described above is provided on the outer surface of the side wall, The outer shape was further increased, and the loading efficiency was further deteriorated.
JP-A-2005-206210 JP 2006-168744 A

本発明は、上記の問題を解決するためになしたもので、側壁内面に保冷用もしくは保温用の機能保持材を収納して使用する断熱容器として、側壁内面に前記機能保持材を収納する凹部を設けることで、容器内部に所定の内容積を確保できて収納効率を低下させることがなくて、しかも、肉厚のボリュームが大きくなるコーナー部の肉盗みの構造を利用して、側壁の厚みを大きくしなくても、断熱効果や強度を低下させずに容器持ち上げ用の手掛け部を設けることができ、容器外形を過度に大きくする必要がなくて、容器の収納効率や輸送効率に優れ、また資材の節約の効果もある断熱容器を提供するものである。   The present invention has been made in order to solve the above problems, and as a heat insulating container for storing and using a function retaining material for cold insulation or heat retention on the inner surface of the side wall, a recess for storing the function retaining material on the inner surface of the side wall The thickness of the side wall can be secured by utilizing the structure of stealing the corner portion, which can secure a predetermined internal volume inside the container without reducing the storage efficiency and increases the volume of the wall thickness. Even without increasing the size, it is possible to provide a handle for lifting the container without reducing the heat insulation effect and strength, and it is not necessary to make the outer shape of the container excessively large, and the container storage efficiency and transport efficiency are excellent. In addition, the present invention provides an insulated container that also has an effect of saving materials.

上記の課題を解決する本発明の断熱容器は、合成樹脂発泡体を主材にして形成された平面矩形の容器本体と蓋体とからなる断熱容器であって、前記容器本体の少なくとも一方の相対向する側壁の内面に、保冷もしくは保温のための機能保持材を収納する凹部が形成され、前記容器本体の少なくとも一方の対角位置の両コーナー部の外側において、側壁外面によるコーナー外形に対して肉盗みになる面取り状の切り欠き部分が上部を残余して下部側に形成されることにより、残余した上部が手掛け部として形成されてなることを特徴とする。   The heat insulating container of the present invention that solves the above problems is a heat insulating container comprising a flat rectangular container main body and a lid formed by using a synthetic resin foam as a main material, and at least one relative to the container main body. On the inner surface of the facing side wall, a concave portion for storing a function retaining material for cold insulation or heat insulation is formed, and on the outer side of both corner portions of at least one diagonal position of the container main body, with respect to the corner outer shape by the side wall outer surface A chamfered cutout portion that becomes a stealer is formed on the lower side with the upper portion remaining, and the remaining upper portion is formed as a handle portion.

この断熱容器によれば、内部に内容物とともに保冷もしくは保温のための機能保持材を収納するものであるにも拘わらず、側壁内面の凹部に機能保持材を収納することで、容器内部に所定の容積を確保して収納部空間として有効利用できる。また、積み卸し等の取り扱い作業においては、例えば一人の作業者が少なくとも一方の対角位置のコーナー部に有する前記手掛け部に手を掛けるようにして容易に持ち上げることができる。   According to this heat insulating container, the function retaining material is stored in the concave portion on the inner surface of the side wall in spite of storing the function retaining material for keeping cold or warming together with the contents inside. Can be effectively used as a storage space. In handling operations such as loading and unloading, for example, one worker can easily lift the handle by placing it on the handle portion at the corner portion of at least one diagonal position.

しかも、前記手掛け部は、前記凹部の部分の側壁外側に必要な肉厚を持たせるために肉厚のボリュームが大きくなるコーナー部の外側に、肉盗みになる面取り状の切り欠き部分を下部に形成して、上部に手掛け部を設けているので、側壁には手掛け部のための凹設部分や厚肉部分を有さず、そのため側壁の肉厚、ひいては容器外形が過度に大きくなることがない。   In addition, the handle portion has a chamfered cutout portion for stealing the meat on the outer side of the corner portion where the volume of the wall thickness increases in order to provide the necessary thickness outside the side wall of the concave portion. Since the handle is formed on the upper part, the side wall does not have a recessed part or a thick part for the handle, so that the thickness of the side wall and thus the outer shape of the container may become excessively large. Absent.

前記の断熱容器において、四つの各コーナー部の外側において、それぞれの下部に面取り状の切り欠き部分が形成されることにより、上部に手掛け部が形成されているものとすることができる。この場合、前後左右のどの方向からでも、対角位置のコーナー部に有する手掛け部に手を掛けて容器を持ち上げることができ、取り扱い作業上さらに好ましいものとなる。   In the above-described heat insulating container, a chamfered cutout portion is formed at each lower portion outside each of the four corner portions, so that a handle portion can be formed at the upper portion. In this case, the container can be lifted by placing a hand on the handle portion provided at the corner portion at the diagonal position from any of the front, rear, left and right directions, which is further preferable in terms of handling work.

また、前記の断熱容器において、四周の各側壁の内面に、機能保持材を収納する凹部が形成されてなるものがよく、これにより内容物の周囲に機能保持材を収納でき、保冷や保温効率をさらに高めることができる。   Further, in the above-mentioned heat insulating container, it is preferable that the inner surface of each side wall of the four circumferences is formed with a recess for storing the function-retaining material, so that the function-retaining material can be stored around the contents, so Can be further enhanced.

前記の断熱容器において、前記凹部を含む側壁が、該凹部の部分の側壁外側に少なくとも使用上必要な肉厚を保有するように形成されるとともに、隣接する両側壁が交わるコーナー部に少なくとも使用上必要な肉厚を保有するように、側壁外面によるコーナー外形に対して前記切り欠き部分が形成されてなるものとすることができる。これにより、各側壁及びコーナー部において、所定の断熱効果や強度を確保できる。   In the heat insulating container, the side wall including the recess is formed to have at least a necessary thickness on the outside of the side wall of the recess, and at least used at a corner portion where adjacent side walls intersect. The notch portion may be formed with respect to the corner outer shape of the side wall outer surface so as to have a necessary thickness. Thereby, a predetermined heat insulation effect and intensity | strength are securable in each side wall and corner part.

上記したように、本発明の断熱容器によれば、積み卸し等の運搬上の取り扱いにおいては、コーナー部に設けた手掛け部に手を掛けるようにして容易に持ち上げることができる。しかも、側壁内面に保冷もしくは保温用の機能保持材を収納できる凹部を設けたことより、容器内部に所定の容積を確保して収納部空間として有効利用でき、前記のように手掛け部を有するものであっても、高い収納効率を保持できる。   As described above, according to the heat insulating container of the present invention, in handling such as loading and unloading, the container can be easily lifted by placing a hand on the handle portion provided at the corner portion. In addition, since the inner surface of the side wall is provided with a recess capable of storing a function retaining material for cold or heat retention, a predetermined volume can be secured inside the container and effectively used as a storage space, and has a handle as described above. Even so, high storage efficiency can be maintained.

特に、本発明の断熱容器の場合は、前記凹部の部分の側壁外側に所定の肉厚を持たせることで肉厚のボリュームが大きくなるコーナー部の外側に、肉盗みになる面取り状の切り欠き部分を下部に形成して、該コーナー部の上部に手掛け部を設けているので、側壁には手掛け部のための凹設部分や厚肉部分を有さず、そのため該側壁の肉厚を大きくしなくてもよく、容器外形が過度に大きくなることがない。したがって、容器外形に対する収納効率が高められ、輸送車両への積載効率及び輸送効率を向上できることになる。また、肉盗み構造のために資材の節約にもなり、コスト低下にも寄与できる。   In particular, in the case of the heat insulating container of the present invention, a chamfered cutout that becomes a stealing meat is provided on the outside of the corner portion where the volume of the wall is increased by giving a predetermined thickness to the outside of the side wall of the concave portion. Since the part is formed in the lower part and the handle is provided at the upper part of the corner part, the side wall does not have a recessed part or a thick part for the handle, so the thickness of the side wall is increased. The outer shape of the container does not become excessively large. Therefore, the storage efficiency with respect to the outer shape of the container can be increased, and the loading efficiency and the transport efficiency on the transport vehicle can be improved. In addition, the meat stealing structure saves materials and contributes to cost reduction.

次に本発明の実施の形態を図面に示す実施例に基づいて説明する。   Next, embodiments of the present invention will be described based on examples shown in the drawings.

図1は本発明の1実施例を示す容器本体と蓋体との分離した斜視図、図2は同上の下方からの斜視図、図3は容器本体の平面図、図4は容器本体と蓋体の半部縦断正面図、図5は容器本体と蓋体の半部縦断側面図である。   1 is a perspective view of a container body and a lid body separated from each other, FIG. 2 is a perspective view from below, FIG. 3 is a plan view of the container body, and FIG. 4 is a container body and lid. FIG. 5 is a half longitudinal sectional side view of the container body and the lid.

本発明の断熱容器Aは、平面矩形で上方に開口する容器本体10と、前記容器本体10の上面を覆う蓋体20とよりなり、両者共に合成樹脂発泡体を主材とする材料により形成されてなる。   The heat insulating container A of the present invention is composed of a container body 10 that is a rectangular plane and opens upward, and a lid body 20 that covers the upper surface of the container body 10, both of which are formed of a material mainly composed of a synthetic resin foam. It becomes.

前記容器本体10は、底部11と四周の各側壁12とにより内容物Bに対応した収納部空間が形成されてなる。10aは側壁上端の開口端部を示す。この容器本体10における少なくとも一方の相対向する側壁の内面、例えば図のように四周の各側壁12の内面には、それぞれ保冷のための蓄冷材や冷却材或いは保温のための蓄熱材等の機能保持材Cを収納する凹部13が、側壁外側に断熱容器として求められる必要最低量の肉厚T1を少なくとも保有するように形成されており、前記収納部空間に所定の立法体形状の内容物Bを収納した状態において、前記機能保持材Cを前記凹部13に挿入し収納できるようになっている。前記凹部13は各側壁12の両側端部に本来の側壁内面を残して中央部に形成されている。   The container body 10 is formed with a storage space corresponding to the contents B by the bottom 11 and the four side walls 12. 10a shows the opening edge part of the upper end of a side wall. On the inner surface of at least one opposite side wall of the container body 10, for example, the inner surface of each side wall 12 around the four sides as shown in the figure, functions of a cold storage material, a cooling material, a heat storage material for heat retention, etc. The concave portion 13 for storing the holding material C is formed so as to hold at least the minimum necessary thickness T1 required as a heat insulating container on the outer side of the side wall, and the content B having a predetermined legislature shape in the storage portion space. The function retaining material C can be inserted into the recess 13 and stored. The concave portion 13 is formed in the central portion while leaving the original inner surface of the side wall at both end portions of each side wall 12.

前記のように、凹部13が内面に形成された側壁12は、該凹部13の部分の側壁外側に少なくとも前記肉厚T1を保有することから、該側壁12としての厚みが前記凹部を有さない場合の側壁の厚みよりも大きく設定されており、またそのため、隣接する二つの側壁12が交わる四つのコーナー部14において肉厚のボリュームが大きくなっている。   As described above, the side wall 12 in which the concave portion 13 is formed on the inner surface has at least the thickness T1 outside the side wall of the concave portion 13, so that the thickness of the side wall 12 does not have the concave portion. In this case, the thickness is set larger than the thickness of the side wall, and the volume of the wall thickness is increased at the four corner portions 14 where the two adjacent side walls 12 intersect.

本発明の場合は、前記の肉厚のボリュームが大きくなっているコーナー部のうちの少なくとも一方の対角位置のコーナー部、好ましくは図のように四つの各コーナー部14の外側において、本来の側壁外面による開口端部10aの外形の上部を残余して下部に、側壁外面によるコーナー外形に対して主として傾斜面による肉盗みになる面取り状の切り欠き部分15が形成され、これにより残余した前記上部が突出状をなす容器持ち上げ用の手掛け部16として形成されており、内容物Bを収納した状態において、該手掛け部16に手を掛けて容器を持ち上げることができるようになっている。前記切り欠き部分15により形成される手掛け部16は、一方の対角位置の両コーナー部14に設けておくだけでもよいが、容器持ち上げ作業の容易性及び肉盗みによる資材節約の効果の点から、図のように四つの各コーナー部14に設けておくのが好ましい。   In the case of the present invention, at the corner portion of at least one of the corner portions where the volume of the wall thickness is large, preferably outside the four corner portions 14 as shown in the figure, A chamfered cutout portion 15 that is mainly stealed by an inclined surface with respect to the corner outer shape of the side wall outer surface is formed in the lower portion while leaving the upper portion of the outer shape of the opening end portion 10a by the outer side surface of the side wall. The upper portion is formed as a handle portion 16 for lifting the container so that the container B can be lifted by placing the hand on the handle portion 16 in a state where the contents B are stored. The handle portion 16 formed by the cutout portion 15 may be provided only at both corner portions 14 at one diagonal position. However, from the viewpoint of ease of lifting the container and saving material by stealing meat. As shown in the figure, it is preferable to provide at each of the four corner portions 14.

前記面取り状の切り欠き部分15は、前記側壁12に前記凹部13を有する場合、該側壁12における凹部13に対応する外面よりもコーナー部14側においてコーナー稜線部を含めて切欠形成され、該凹部13の部分の側壁外側に前記肉厚T1を少なくとも保有するように設定される。前記切り欠き部分15の形状は、前記コーナー部14の肉厚のボリュームに応じて、容器内部の側壁内面によるコーナー部分14aから外面までの厚みが、断熱容器として求められる必要最低量の肉厚T2を少なくとも保有するように設定されるもので、そのため、図1〜図5の実施例では2面の傾斜面15a,15aにより切欠形成されている。   When the chamfered cutout portion 15 has the concave portion 13 in the side wall 12, the chamfered cutout portion 15 is cut out including the corner ridge line portion on the corner portion 14 side from the outer surface corresponding to the concave portion 13 in the side wall 12, and the concave portion The thickness T1 is set at least at the outside of the side wall of the portion 13. The shape of the cutout portion 15 is such that the thickness from the corner portion 14a to the outer surface by the inner wall of the side wall inside the container is the minimum necessary thickness T2 required as a heat insulating container according to the volume of the corner portion 14. Therefore, in the embodiment shown in FIGS. 1 to 5, notches are formed by two inclined surfaces 15 a and 15 a.

このほか、前記面取り状の切り欠き部分15としては、図6(a)のように一つの傾斜面15bにより形成することも、また同図(b)のように円弧状の丸みのついた面取り形状にして実施することもできる。また、前記凹部13を有する側壁12と、前記凹部を有さない側壁12aとによるコーナー部14においても、前記同様の切り欠き部分15を形成できる。この場合、前記凹部を有さない側壁12aの側では、図6(c)のように、該側壁12aにおける容器内部と対応する位置よりコーナー部14の側で切欠形成され、該側壁12が所定の厚みを保有するように設定される。   In addition, the chamfered cutout portion 15 may be formed by one inclined surface 15b as shown in FIG. 6 (a), or may be chamfered with an arcuate round shape as shown in FIG. 6 (b). It can also be implemented in the shape. In addition, a cutout portion 15 similar to the above can also be formed at the corner portion 14 formed by the side wall 12 having the concave portion 13 and the side wall 12a not having the concave portion. In this case, on the side of the side wall 12a not having the concave portion, as shown in FIG. 6C, a notch is formed on the side of the corner portion 14 from a position corresponding to the inside of the container on the side wall 12a. It is set to possess the thickness of.

前記いずれの場合にも、コーナー部14の外側上部に形成される手掛け部16としては、内容物Bを収納した状態の容器を持ち上げる際に、該手掛け部16が容易に破断しないように、上下方向の厚み寸法T3を設定する。この厚み寸法T3は、素材の合成樹脂発泡体の種類、発泡倍率、前記面取り部分15に対する突出寸法等によって異なるが、好ましくは側壁12の厚みと同程度以上の厚みを保有するものとする。例えば、容器高さの上部約半分を手掛け部16として残余させるように切り欠き部分15を形成することもできるが、上下方向の厚み寸法T3が大きくなるほど、肉盗みの効果が小さくなるので、肉盗みの効果を期待する場合には前記厚み寸法T3をあまり大きくするのは好ましくない。   In any of the above cases, the handle 16 formed on the outer upper portion of the corner portion 14 is arranged so that the handle 16 is not easily broken when the container holding the contents B is lifted. A direction thickness dimension T3 is set. The thickness T3 varies depending on the type of synthetic resin foam of the material, the expansion ratio, the protruding dimension with respect to the chamfered portion 15, and the like, but preferably has a thickness equal to or greater than the thickness of the side wall 12. For example, the cutout portion 15 can be formed so that the upper half of the container height remains as the handle portion 16, but the effect of meat stealing decreases as the thickness dimension T3 in the vertical direction increases. If the effect of theft is expected, it is not preferable to make the thickness dimension T3 too large.

図の場合、前記底部11には、四隅部に内容物Bを受ける受け部17を残して凹部18が形成されており、収納される内容物Bとの間に間隙を保有できるようになっている。この場合、前記凹部18の底部下側に断熱容器として必要な厚みを保有するように形成される。   In the case of the figure, a recess 18 is formed in the bottom 11 leaving the receiving portions 17 for receiving the contents B at the four corners, so that a gap can be held between the contents B to be stored. Yes. In this case, it forms so that the thickness required as a heat insulation container may be hold | maintained under the bottom part of the said recessed part 18. FIG.

なお、前記容器本体10の底部11の下面には、内方部の所要の個所に、脚部として複数の凸部19が、予冷等のために非蓋着状態での積み重ねる際、下段の容器本体10の開口部に嵌り込むように配設されている。前記底部11の短辺に沿う凸部19は、前記積み重ねの際の通気部を確保できるように間隔をおいて設けられている。   In addition, on the lower surface of the bottom 11 of the container main body 10, when a plurality of convex portions 19 as legs are stacked at a required position in the inner portion in a non-covered state for precooling or the like, the lower container It arrange | positions so that it may fit in the opening part of the main body 10. FIG. The convex portions 19 along the short side of the bottom portion 11 are provided at intervals so as to ensure a ventilation portion in the stacking.

前記蓋体20は、容器本体10の開口部に嵌合して被着できるものであれば、どのような形態や被着構造をなすものであってもよいが、図の場合は、前記容器本体10の開口端部10aに対応した外形を有するものからなる。この蓋体20の下面には、周縁部に前記容器本体10の開口端部10aに載設する切欠段部21が形成され、その内方部分22が前記容器本体10の開口部に嵌合するように設けられている。   As long as the lid 20 can be fitted and attached to the opening of the container body 10, the lid 20 may have any form or attachment structure. The main body 10 has an outer shape corresponding to the open end 10a. On the lower surface of the lid body 20, a notch step portion 21 is formed on the peripheral edge portion so as to be mounted on the opening end portion 10 a of the container body 10, and an inner portion 22 of the cutout portion 21 is fitted into the opening portion of the container body 10. It is provided as follows.

また前記蓋体20の上面には、蓋着状態での積み重ねの際に、上段になる容器本体10の底部下面の凸部19と嵌合する配置で突起部23が設けられており、位置ずれなく安定性よく積み重ねることができるようになっている。   Further, the upper surface of the lid body 20 is provided with a projection 23 arranged so as to be fitted to the convex portion 19 on the bottom lower surface of the bottom of the container main body 10 when stacked in a cover state. It can be stacked with good stability.

前記の容器本体10及び蓋体20の構成材料である合成樹脂発泡体としては、ポリスチレンとポリオレフィンの複合樹脂、ポリスチレン、ハイインパクトポリスチレン、スチレン−エチレン共重合体、スチレン−無水マレイン酸共重合体、スチレン−アクリロニトリル共重合体等のポリスチレン系樹脂、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体等のポリオレフィン系樹脂、ポリエチレンテレフタレート等のポリエステル系樹脂、ポリ乳酸樹脂等の各種合成樹脂の発泡体を用いることができる。中でも、ポリスチレンとポリオレフィンの複合樹脂のビーズ発泡体による成形体が好適に用いられる。必要に応じて、表面に前記発泡体に非発泡の表皮層を設けることもできる。前記発泡体の発泡倍率は材質や内容物等によっても異なるが、通常3〜50倍が好ましい。   As the synthetic resin foam which is a constituent material of the container body 10 and the lid 20, a composite resin of polystyrene and polyolefin, polystyrene, high impact polystyrene, styrene-ethylene copolymer, styrene-maleic anhydride copolymer, Polystyrene resins such as styrene-acrylonitrile copolymer, polyolefin resins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyester resins such as polyethylene terephthalate, and various synthetic resin foams such as polylactic acid resin are used. be able to. Especially, the molded object by the bead foam of the composite resin of a polystyrene and polyolefin is used suitably. If necessary, a non-foamed skin layer may be provided on the surface of the foam. The expansion ratio of the foam varies depending on the material and contents, but is usually preferably 3 to 50 times.

ポリスチレンとポリオレフィンの複合樹脂のビーズ発泡体の成形品は、同じ発泡倍率のポリプロピレン系樹脂ビーズの成形品に比べて強度があり、また、容器成形後の収縮率が低く寸法精度もよい。さらに、スチレン系樹脂ビーズの発泡成形品に比べて擦れによる粉が出難い長所もある。   A molded product of a polystyrene-polyolefin composite resin bead foam has strength compared to a molded product of polypropylene resin beads having the same expansion ratio, and has a low shrinkage ratio after molding a container and good dimensional accuracy. Furthermore, there is an advantage that powder due to rubbing is less likely to be produced as compared with foamed molded products of styrene resin beads.

上記実施例の断熱容器Aの使用において、容器本体10の内部に包装対象の内容物Bを収納するとともに、側壁12の内面の凹部13に例えば蓄冷材や蓄熱材等の機能保持材Cを収納し、上部開口に蓋体20を被着して使用する。この使用において、側壁内面の凹部13に容器内部は本来の容積を確保して収納部空間として有効に利用でき、収納効率を向上できる。   In the use of the heat insulating container A of the above embodiment, the contents B to be packaged are stored inside the container body 10 and the function retaining material C such as a cold storage material or a heat storage material is stored in the recess 13 on the inner surface of the side wall 12. The lid 20 is attached to the upper opening for use. In this use, the inside of the container can be effectively used as a storage space by ensuring the original volume in the recess 13 on the inner surface of the side wall, and storage efficiency can be improved.

また、積み卸し等の取り扱い作業においては、一人でも対角位置のコーナー部にある前記手掛け部16に両手をかけて容易に持ち上げることができる。4つの各コーナー部の外側に手掛け部16が形成されている場合、作業者はどの方向からでも前記のように対角位置のコーナー部の手掛け部16に手を掛けて持ち上げることができる。しかも、前記手掛け部16は、前記凹部13の形成に伴って側壁外側に所定の肉厚T1を確保することで肉厚のボリュームが大きくなるコーナー部の外側において、下部の切り欠き部分15を切欠形成することにより、側壁外面に対し凹設したり突出させることなく手掛け部16を設けているので、手掛け部16を有するものであるにも拘わらず、容器外形が従来の側壁中央に手掛け部16を設けた形態に比して過度に大きくならず、そのため容器外形に対する収納効率が高められ、輸送車両への積載効率も高く、輸送効率も高められる。しかも肉盗み構造のために資材の節約にもなっており、コスト低下にも寄与できる。   In handling operations such as loading and unloading, even one person can easily lift the handle portion 16 at the corner portion of the diagonal position with both hands. When the handle 16 is formed on the outside of each of the four corners, the operator can lift the handle by placing the hand on the handle 16 at the corner in the diagonal position as described above. In addition, the handle portion 16 has a notch portion 15 formed on the lower side outside the corner portion where a predetermined volume T1 is secured on the outside of the side wall as the concave portion 13 is formed. By forming the handle portion 16 without being recessed or protruding from the outer surface of the side wall, the outer shape of the container has the handle portion 16 at the center of the conventional side wall even though the handle portion 16 is provided. Therefore, the storage efficiency with respect to the outer shape of the container is increased, the loading efficiency on the transportation vehicle is increased, and the transportation efficiency is also increased. Moreover, the meat stealing structure also saves materials, which can contribute to cost reduction.
