Description

本発明は、マグロ、ブリ等の大型魚を保冷輸送する際に使用する発泡合成樹脂製の保冷容器に関する。   The present invention relates to a cold insulated container made of a synthetic foam resin used for transporting a large-sized fish such as tuna and yellowtail while keeping cold.

従来、マグロ、ブリ等の大型魚を保冷輸送する際に使用する発泡合成樹脂製の保冷容器として、大型魚の重量より受ける容器の前後方向の大きな曲げモーメントに対応するため、容器本体の底壁と左右の側壁との間の稜部分に前後方向に延びる肉厚補強部を設けたものが知られている(特許文献1参照)。   Conventionally, as a cold insulation container made of foamed synthetic resin used for transporting large fish such as tuna and yellowtails in cold storage, the bottom wall of the container body is used to cope with a large bending moment in the front-rear direction of the container that is received from the weight of the large fish. What provided the thickness reinforcement part extended in the front-back direction in the ridge part between right and left side walls is known (refer patent document 1).

特許文献1に示された保冷容器においては、容器本体の底壁と左右の側壁との間の稜部分に設けられた肉厚補強部により容器本体の底壁及び左右の側壁の強度が高められるので、大型魚の重量により容器の底壁が抜ける、容器が撓む等の不具合を防止できる。   In the cold storage container shown in Patent Document 1, the strength of the bottom wall and the left and right side walls of the container body is increased by the thickness reinforcing portion provided at the ridge portion between the bottom wall and the left and right side walls of the container body. Therefore, problems such as the bottom wall of the container coming out due to the weight of the large fish and the container being bent can be prevented.

以下、本発明の保冷容器を図面に示す実施形態に基づき説明する。   Hereinafter, the cold insulation container of the present invention will be described based on the embodiments shown in the drawings.

図1において、1は発泡合成樹脂よりなる保冷容器であって、収容される大型魚Zの大きさに応じた大きさに形成された上面が開口する箱状の容器本体10と、この容器本体10の上面開口部を開閉するように容器本体10に対して着脱可能に取付けられた上蓋20とによって構成されている。ここで、前記発泡合成樹脂としては、特に限定されないが、例えば、発泡ポリスチレン、発泡ポリエチレン、発泡ポリプロピレン等の各種発泡合成樹脂が利用される。   In FIG. 1, reference numeral 1 denotes a cold storage container made of foamed synthetic resin, a box-shaped container main body 10 having an upper surface formed in a size corresponding to the size of a large fish Z to be accommodated, and the container main body The upper lid 20 is detachably attached to the container main body 10 so as to open and close the upper surface opening of 10. Here, the foamed synthetic resin is not particularly limited, but various foamed synthetic resins such as foamed polystyrene, foamed polyethylene, and foamed polypropylene are used.

容器本体10は、図2に示すように、平面方形に形成された底壁11と、この底壁11の両長辺側端部に対向して垂直状に立設された左右の側壁12,12と、前記底壁11の両短辺側端部に対向して垂直状に立設され、左右の側壁12,12と互いに連結された前後の側壁13,13とによって深型の箱状に形成されている。底壁11と左右の側壁12,12との間の稜部分には、凹状に湾曲した円弧状の傾斜面部14,14が前後の側壁13,13に近い両側部分を除く所定の長さに亘って設けられており、この傾斜面部14,14によって底壁11の内面が大型魚Zの胴体形状に対応するように凹面形状に形成されている。傾斜面部14は、中央部分(底壁11の長辺側中央を中心として底壁11の長辺側寸法の約1/2〜1/4程度の部分)14aを大きな径(例えば、R50〜R200)の円弧面とし、その両側部分14b,14bを前後の側壁13,13に向かって次第に径が細くなるテーパー状の円弧面として形成されている。容器本体10は、底壁11の内面を傾斜面部14,14によって大型魚Zの胴体形状に対応するように凹面形状に形成させたことで、大型魚Zを収容すると、大型魚Zが底壁11の内面に沿って大型魚Zの荷重が分散された状態で支持されるので、大型魚Zの荷重が底壁11の1箇所に集中することが回避されるようになる。しかも、傾斜面部14,14が底壁11と左右の側壁12,12との間の稜部分の肉厚補強部として作用するので、底壁11及び左右の側壁12,12の強度が高められるようになる。前後の側壁13,13の内面には、大型魚Zの頭部又は尾部が当たる部分に発泡合成樹脂より硬質の板材で形成した補強板15,15が着脱可能に保持されている。補強板15は、側壁13の底部から途中まで内方へ突出して形成された保持部16によって着脱可能に保持されている。保持部16は、補強板15を前後方向の内方側から規制する前後規制部16aと、補強板15を左右方向の両側から規制する左右規制部16b,16bとを有し、この前後規制部16a及び左右規制部16b,16bにより補強板15を上下方向に抜き挿し可能なポケット状の保持溝17を形成し、この保持溝17に補強板15の下端部分を挿し込むことで、側壁13の内面に補強板15を着脱可能に保持している。補強板15の材質、面積及び厚みは、収容する大型魚Zの重量に応じて任意に選択することができる。補強板15の材質としては、発泡合成樹脂より強度が高い材質、例えば、段ボール、プラスチック段ボール、各種プラスチック、ベニヤ板等が挙げられる。左右の側壁12,12及び前後の側壁13,13の上端面、即ち、容器本体10の上端面には、内縁全周に亘って上向きに嵌合用凸条18が設けられている。   As shown in FIG. 2, the container body 10 includes a bottom wall 11 formed in a flat rectangular shape, and left and right side walls 12 that are vertically erected opposite to both long side ends of the bottom wall 11. 12 and the front and rear side walls 13, 13 which are vertically erected in opposition to both short side end portions of the bottom wall 11 and are connected to the left and right side walls 12, 12 to form a deep box shape. Is formed. At the ridge portion between the bottom wall 11 and the left and right side walls 12, 12, the arcuate inclined surface portions 14, 14 curved in a concave shape extend over a predetermined length excluding both side portions close to the front and rear side walls 13, 13. The inclined surfaces 14, 14 are formed in a concave shape so that the inner surface of the bottom wall 11 corresponds to the body shape of the large fish Z. The inclined surface portion 14 has a large diameter (for example, R50 to R200) 14a at a central portion (a portion that is about ½ to ¼ of the long side dimension of the bottom wall 11 with the center on the long side of the bottom wall 11). ), And both side portions 14b and 14b are formed as tapered arc surfaces whose diameters gradually decrease toward the front and rear side walls 13 and 13, respectively. The container main body 10 is formed in a concave shape so that the inner surface of the bottom wall 11 corresponds to the trunk shape of the large fish Z by the inclined surface portions 14 and 14, and when the large fish Z is accommodated, the large fish Z becomes the bottom wall. 11 is supported in a state where the load of the large fish Z is distributed along the inner surface of the bottom wall 11, it is avoided that the load of the large fish Z is concentrated on one place of the bottom wall 11. In addition, since the inclined surface portions 14 and 14 act as a thickness reinforcing portion of the ridge portion between the bottom wall 11 and the left and right side walls 12 and 12, the strength of the bottom wall 11 and the left and right side walls 12 and 12 can be increased. become. On the inner surfaces of the front and rear side walls 13 and 13, reinforcing plates 15 and 15 formed of a plate material harder than foamed synthetic resin are detachably held on the portion where the head or tail of the large fish Z hits. The reinforcing plate 15 is detachably held by a holding portion 16 that protrudes inward from the bottom of the side wall 13 partway. The holding portion 16 includes a front / rear restricting portion 16a that restricts the reinforcing plate 15 from the inner side in the front / rear direction, and left / right restricting portions 16b, 16b that restrict the reinforcing plate 15 from both sides in the left / right direction. 16a and left and right restricting portions 16b and 16b form a pocket-shaped holding groove 17 into which the reinforcing plate 15 can be inserted and removed in the vertical direction, and the lower end portion of the reinforcing plate 15 is inserted into the holding groove 17 so that the side wall 13 A reinforcing plate 15 is detachably held on the inner surface. The material, area, and thickness of the reinforcing plate 15 can be arbitrarily selected according to the weight of the large fish Z to be accommodated. Examples of the material of the reinforcing plate 15 include materials having higher strength than foamed synthetic resin, such as corrugated cardboard, plastic corrugated cardboard, various plastics, and plywood. On the upper end surfaces of the left and right side walls 12, 12 and the front and rear side walls 13, 13, i.e., the upper end surface of the container body 10, a fitting protrusion 18 is provided upward over the entire inner edge.

一方、上蓋20は、図3に示すように、下面が開口した浅型の箱状に形成されており、下端面の外縁全周に亘って下向きに嵌合用凸条21を設け、この嵌合用凸条21を容器本体10の嵌合用凸条18に嵌合することによって容器本体10に着脱可能に取付けられるようになっている。   On the other hand, as shown in FIG. 3, the upper lid 20 is formed in a shallow box shape with an open bottom surface, and is provided with a fitting ridge 21 downward over the entire outer edge of the lower end surface. By fitting the ridges 21 to the fitting ridges 18 of the container body 10, the ridges 21 are detachably attached to the container body 10.

上述のように構成された保冷容器1は、図1に示すように、容器本体10内にマグロ、ブリ等の大型魚Zをまるごと収容するとともに、その上から保冷剤(図示せず)を詰め、容器本体10を上蓋20で閉じた状態で、消費地まで輸送されるようになっている。この保冷容器1では、例えば輸送時等に保冷容器1内の大型魚Zが前後方向に移動した場合、大型魚Zの鋭利な頭部又は尾部は容器本体10の前後の側壁13,13の内面に設けられた補強板15,15に当たることとなり、大型魚Zの鋭利な頭部又は尾部が左右の側壁13,13に直接当たることはない。このため、前後の側壁13,13において亀裂が発生する等の不具合がなく、前後の側壁13,13の破損が防止されて保冷容器1の信頼性の向上が図れる。   As shown in FIG. 1, the cold storage container 1 configured as described above accommodates a whole large fish Z such as tuna and yellowtail in a container main body 10, and is filled with a cold storage agent (not shown) from above. In the state where the container body 10 is closed by the upper lid 20, the container body 10 is transported to the consumption place. In this cool container 1, for example, when the large fish Z in the cool container 1 moves in the front-rear direction during transportation, the sharp head or tail of the large fish Z is the inner surface of the side walls 13, 13 on the front and rear of the container body 10. The sharp head or tail of the large fish Z does not directly contact the left and right side walls 13 and 13. For this reason, there is no malfunction, such as a crack occurring in the front and rear side walls 13, 13, damage to the front and rear side walls 13, 13 is prevented, and the reliability of the cold container 1 can be improved.

また、保冷容器1は、補強板15を容器本体10の保持部16に着脱可能に保持させているので、容器本体10の構造を簡単にして当該容器本体10の製造が容易に行えるとともに、輸送後にはいつでも簡単に容器本体10から補強板15を取外すことができて補強板15の分離回収が簡単であり、廃棄処分が容易に行える。   Moreover, since the cold storage container 1 has the reinforcing plate 15 detachably held on the holding portion 16 of the container main body 10, the structure of the container main body 10 can be simplified and the container main body 10 can be easily manufactured and transported. Later, the reinforcing plate 15 can be easily removed from the container body 10 at any time later, and the separation and recovery of the reinforcing plate 15 is simple, and disposal can be easily performed.

更に、保冷容器1は、補強板15を容器本体10の保持部16に形成した保持溝17に挿し込んで保持させているので、補強板15の容器本体10への取付けを容易に行うことができるとともに、輸送時等に補強板15が前後方向及び左右方向に位置ずれする虞がない。   Further, since the cold container 1 holds the reinforcing plate 15 by inserting it into the holding groove 17 formed in the holding portion 16 of the container body 10, it is possible to easily attach the reinforcing plate 15 to the container body 10. In addition, there is no possibility that the reinforcing plate 15 is displaced in the front-rear direction and the left-right direction during transportation.

図4は、本発明の他の実施形態の保冷容器に容器本体及び上蓋として兼用で使用される容器部材30を示している。この容器部材30は、前記実施形態の容器本体10より少し浅型の箱状に形成されている点、上端面の各辺の半分ずつ内縁と外縁とが交互に交替するように嵌合用凸条31,32が中心点に対して点対称に形成されている点を除けば前記実施形態の容器本体10と略同じである。   FIG. 4 shows a container member 30 that is used as a container main body and an upper lid for a cold container according to another embodiment of the present invention. The container member 30 is formed in a slightly shallower box shape than the container body 10 of the above embodiment, and the fitting ridges so that the inner edge and the outer edge are alternately alternated by half each side of the upper end surface. Except for the point 31 and 32 being formed in point symmetry with respect to the center point, it is substantially the same as the container main body 10 of the said embodiment.

前記容器部材30は、これと同一形状の容器部材30を開口部が向き合うように上下反転して突き合わせることで、両容器部材30,30の嵌合用凸条31,32が互いに嵌合して保冷容器が得られる。この容器部材30を用いて得られた保冷容器においても、前記実施形態の保冷容器1と同様の効果を得ることができる。   The container member 30 has the same shape of the container member 30 turned upside down so that the openings face each other, so that the fitting protrusions 31 and 32 of the container members 30 and 30 are fitted to each other. A cold container is obtained. Also in the cold insulation container obtained using this container member 30, the same effect as the cold insulation container 1 of the said embodiment can be acquired.

以上、本発明を実施形態に基づき具体的に説明したが、本発明は前記実施形態に限定されるものではなく、その要旨を逸脱しない範囲で種々変更可能であることはいうまでもない。   Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

例えば、補強板15は、前後の側壁13,13の双方に設けるのではなく、場合によっては一方だけに設けるようにしてもよい。また、補強板15は、側壁13における左右方向の中央領域全面に設けるのではなく、側壁13の大型魚Zの頭部又は尾部が当たる部分に部分的に設けるようにしてもよい。また、補強板15を保持する保持部16の保持溝17はポケット状ではなく、スリット状にして補強板15の下端辺又は両側端辺を挿し込んで保持するようにしてもよい。また、保持部16は、前後規制部16aと左右規制部16b,16bとを有するのではなく、前後規制部16a又は左右規制部16b,16bの片方を有するだけでもよい。また、保持部16は、側壁13に形成するのではなく、底壁11又は左右の側壁12,12の前後の側壁13,13の近傍に形成するようにしてもよい。また、補強板15は、保持部16によって容器本体10の側壁13に保持させるのではなく、接着剤等によって容器本体10の側壁13に接着するようにしてもよい。また、補強板15の形状は方形ではなく、円形、楕円形、方形以外の多角形その他形状でもよい。また、前後の側壁13に板材で形成した補強板15を設けるようにしているが、補強板以外、即ち、板材以外のもので形成した補強部材を設けるようにしてもよい。また、側壁13の大型魚Zの頭部又は尾部が当たる部分に容器本体10とは別体の補強部材を設けるようにしているが、側壁13の大型魚Zの頭部又は尾部が当たる部分に補強用硬質部を一体に設けるようにしてもよい。尚、側壁13の大型魚Zの頭部又は尾部が当たる部分に補強用硬質部を一体に設ける場合、例えば側壁13の当該部分を肉厚にしたり、当該部分の表面を硬化処理したりする等して硬度を増大させる。更に、容器本体10の傾斜面部14は円弧面ではなく、平斜面でもよい。尚、傾斜面部14を平斜面にする場合、中央部分のC面取り加工はC50〜C200が好ましい。   For example, the reinforcing plate 15 may not be provided on both the front and rear side walls 13 and 13 but may be provided on only one side in some cases. Further, the reinforcing plate 15 may be partially provided on a portion of the side wall 13 where the head or tail of the large fish Z hits instead of being provided on the entire lateral central region of the side wall 13. In addition, the holding groove 17 of the holding portion 16 that holds the reinforcing plate 15 may be formed in a slit shape instead of a pocket shape so that the lower end side or both side end sides of the reinforcing plate 15 are inserted and held. Moreover, the holding | maintenance part 16 does not have the front-rear control part 16a and the left-right control parts 16b, 16b, but may have only one of the front-rear control part 16a or the left-right control parts 16b, 16b. Further, the holding portion 16 may be formed not in the side wall 13 but in the vicinity of the bottom wall 11 or the side walls 13 and 13 before and after the left and right side walls 12 and 12. Further, the reinforcing plate 15 may be adhered to the side wall 13 of the container body 10 by an adhesive or the like instead of being held on the side wall 13 of the container body 10 by the holding portion 16. Further, the shape of the reinforcing plate 15 is not a square, but may be a circle, an ellipse, a polygon other than a square, or other shapes. In addition, the reinforcing plate 15 formed of a plate material is provided on the front and rear side walls 13, but a reinforcing member formed of a material other than the reinforcing plate, that is, a material other than the plate material may be provided. Further, a reinforcing member separate from the container main body 10 is provided at the portion of the side wall 13 where the head or tail of the large fish Z hits, but the portion of the side wall 13 where the head or tail of the large fish Z hits. You may make it provide the hard part for reinforcement integrally. In addition, when providing the hard part for reinforcement integrally in the part which the head or tail part of the large fish Z of the side wall 13 hits, for example, the said part of the side wall 13 is thickened, the surface of the said part is hardened, etc. To increase the hardness. Furthermore, the inclined surface portion 14 of the container body 10 may be a flat slope instead of an arc surface. In addition, when making the inclined surface part 14 into a flat slope, C50 chamfering processing of a center part is preferable C50-C200.
