  However, there is a problem that the foamed synthetic resin has a low hardness while the head and tail of the large fish are sharp. For example, when the large fish moves in the front-rear direction of the container during transportation, the head of the large fish When the portion or the tail strongly hits the inner surfaces of the front and rear side walls of the container, there is a problem that cracks occur in the side walls and the front and rear side walls may be damaged.

  The object of the present invention has been made in view of the above-mentioned problems, and even when a large fish moves in the front-rear direction, the front and rear side walls are prevented from being damaged by the head or tail of the large fish and reliable. The object is to provide a high cold storage container.

In order to achieve the above-described object, a cold storage container according to the present invention is a container for storing large fish made of foamed synthetic resin, and includes a box-shaped container body having an open top surface. In the cold insulation container provided with a thickness reinforcing portion extending in the front-rear direction on at least a part of the ridge portion between the wall and the left and right side walls, the head or tail of the large fish on at least one of the front and rear side walls of the container body A reinforcing plate that is formed separately from the container main body and has stronger strength than the side wall against the force from the direction along the front-rear direction is held by the holding portion formed on the container main body at the contact portion. The holding portion has a front / rear restricting portion that restricts the reinforcing plate from the inner side in the front / rear direction, and is configured so that the reinforcing plate can be inserted / removed in the vertical direction. Features.

According to the above-described configuration, since the reinforcing plate is disposed on at least one of the front and rear side walls of the container body, for example, when the large fish moves in the front-rear direction during transportation, the head or tail of the large fish is the reinforcing plate. It will hit. In addition, since the reinforcing plate is separated from the container body, the container body can have a simple structure, and the container body can be easily manufactured. In addition, since the holding part is configured so that the reinforcing plate can be inserted and removed in the vertical direction, the reinforcing plate can be easily attached to the holding part of the container body when the cold container is used, and the container can be easily attached at any time after transportation. The reinforcing plate can be removed from the main body. For this reason, the reinforcing plate can be separated and recovered from the container main body, and can be easily disposed of. Moreover, since the holding part has the front-rear restricting part, there is no possibility that the reinforcing plate is displaced in the front-rear direction during transportation.

Further, in the cold container of the present invention, the reinforcing plate is arbitrarily desired Tei Rukoto disposed in the central region in the lateral direction in the side walls of the front and rear.

Further, in the cold container of the present invention, the front Symbol holder has a right and left regulating part for regulating the reinforcing plate from both sides in the lateral direction, even shall have been configured to be disconnected and reconnected the reinforcing plate in the vertical direction Good.

According to the above arrangement, since the reinforcing plate Dekiru disconnected and reconnected in the vertical direction, with mounting of the reinforcing plate to the container body is easy, since the holding portion has a left right regulating unit, transportation or the like reinforcing plate no fear that misalignment in the left right direction.

According to the cold storage container of the present invention, since the head or tail of the large fish hits the reinforcing plate , for example, during transportation, the front and rear side walls can sufficiently withstand the head or tail of the large fish, In this case, there is no problem such as cracking, and the front and rear side walls are prevented from being damaged, and the reliability of the cold insulation container can be improved.

  Hereinafter, the cold insulation container of the present invention will be described based on the embodiments shown in the drawings.

  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.

  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 thickness reinforcement portions at the ridges 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 held detachably 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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.
