  By the way, in recent years, fish as a regional brand has been demanded on a nationwide scale. Therefore, it is conceivable to carry this kind of fish using the above-mentioned conventional cold container. However, in the conventional cold storage container, since only one cold storage material installation portion is formed, the cold storage is uniformly held regardless of the type of the stored item. On the other hand, the constitution of fish is not uniform depending on the species. Also, the number of individuals to be stored varies depending on the case. For this reason, if the cold insulation is uniform regardless of the species and the number of individuals, the quality of the fish body is deteriorated.

  Moreover, although the fish body is easy to move in the accommodating portion due to vibration during transportation, the conventional cold container does not have a configuration for holding the fish body in position. For this reason, if the fish moves due to vibration in the housing part, for example, if the fish bodies rub against each other or if they collide strongly with the inner wall surface of the housing part, the fish body will be damaged and the quality (commercial value) of the fish body will be reduced. End up. Further, in recent years, waterless live fish transport has been performed in which a fish is transported to a destination in a dead state without using water, and in this case, in particular, delicate cooling is required.

  Then, in view of the said problem, this invention aims at provision of the cold storage container which can suppress the fall of the quality of a fish body.

The cold storage container according to the present invention has a housing portion for housing a fish body and is formed in a box shape, and a container body in which the fish body is housed in the housing portion from an upper opening portion, and a plate attached to the opening portion An inner lid, an outer lid that covers the inner lid from the upper side thereof and is attached to the container body to seal the opening, and a wall body that partitions the housing portion into a plurality of housing areas in the spreading direction. With
In the inner lid, a plurality of placement areas that can hold the regenerator material and are partitioned from each other are formed so as to extend in the spreading direction of the accommodating portion, and each of the placing areas communicates with the accommodating portion. A supply hole is formed, and cold air of the regenerator material placed in the selected placement area is configured to be supplied from the cold air supply hole to an arbitrary accommodation area partitioned by the wall body , A stepped portion having an inner lid hooking surface on which an outer peripheral portion of the lower surface of the inner lid is placed is formed in the opening, and the inner lid is placed on the stepped portion by placing the inner lid on the stepped portion. A groove that fits into the upper edge of the wall is formed, and the inner lid is formed on the stepped portion of the opening via an adjustment gap between the outer surface and the peripheral wall that forms the opening. By being placed, the position of the opening can be adjusted in the spreading direction of the opening. Further, the outer peripheral portion of the lower surface of the inner lid is formed as an inclined surface that is inclined downward toward the inside, and when the inner lid is placed on the stepped portion, the inclined surface of the inner lid is the stepped portion. It is characterized by being comprised so that the corner | angular part inside may be slid .

  In the above-described configuration, the housing portion of the container main body is divided into a required number of housing areas by the wall body, fish is accommodated from the opening to an arbitrary housing area, an inner lid is attached to the opening, and a plurality of mountings are mounted. When a placement area corresponding to the accommodation area required for keeping the fish body is selected from the placement areas, and the cold storage material is placed in the placement area, the cold storage material is formed from the cold air supply holes formed in the placement area. The cold air of the regenerator material is circulated through the accommodation area by attaching the outer lid to the container body, and the cool body of the regenerator material is indirectly circulated by the cool air of the regenerator material. It is kept cool and the quality of the fish body is maintained.

  In addition, by partitioning the storage portion into a plurality of storage regions by the wall body, even if vibration is applied to the cold insulation container during transport of the cold storage container, the storage portion is narrower than the storage portion by dividing the storage portion by the wall body. Therefore, the movement of the fish body in the accommodating portion due to the vibration is suppressed, and the quality of the fish body is maintained.

Furthermore, depending on the type of fish, a fish body (live fish) that has been cooled until it becomes preliminarily dead is housed in the housing area, and a necessary number of cold storage materials are selected so that the atmosphere temperature of the fish body can be maintained at the deadly state. By placing in the placement area, the fish body is not rapidly cooled by delicate cooling, and the cold storage container can be used for so-called waterless live fish transportation.
In addition, when the inner lid is attached to the opening, the wall body cannot be seen by the inner lid, but, as in the above configuration, the position of the inner lid can be adjusted in the opening direction of the opening, It becomes easy to match the upper edge of the wall with the groove formed in the inner lid.

  In the cold storage container of the present invention, it is possible to adopt a configuration in which a partition wall is formed on the upper surface of the inner lid, a plurality of placement regions are formed by the partition wall, and the cool storage material is held by the partition wall. According to this configuration, the placement area to be selected is clarified, and the placement position of the cold storage material is held by the partition wall.

The cold storage container of the present invention employs a configuration in which a guide surface inclined toward the groove is fitted to the side of the groove so as to be fitted to the upper edge when fitted to the upper edge of the wall body. be able to.

  Since the cold storage container of the present invention includes a wall body that partitions the container body into a required number of storage areas, even if vibration is applied to the cold storage container during the transport of the cold storage container, the cold storage container is stored in the wall body. It can maintain the quality of the fish body by suppressing the movement of the fish body in the accommodation part due to vibration as much as the accommodation area narrower than the accommodation part by partitioning the part, and each cold storage material can be held in the inner lid A plurality of placement areas are formed so as to extend over the entire spreading direction of the accommodating portion, and a cold air supply hole communicating with the accommodating portion is formed for each placement region, and the cold storage placed in the selected placement region Since the cold air of the material is supplied from the cold air supply hole to an arbitrary accommodation area partitioned by the wall body, it can be kept cold according to the type of fish to be accommodated, the number of individuals, etc., and thus maintain the quality of the fish body Can do.

  Hereinafter, a cold insulation container according to an embodiment of the present invention will be described with reference to FIGS. 1 to 9. This cold storage container 1 is suitably used for transport without live fish water that transports (transports) fish in a live fish state by keeping the fish body cold without using water. Note that the target fish that can inhabit for a long time even in the air (not underwater) as compared with other fish is preferable as the fish stored in the cold container 1. This includes, for example, jade grouper (belonging to the perennial grouper).

  First, based on FIG. 1 thru | or FIG. 9, 1st embodiment of the cold storage container 1 of this invention is described. As shown in FIGS. 1 and 2, the cold insulation container 1 includes a container body 2 and a lid 3. The lid 3 includes an inner lid 4 and an outer lid 5. The cold insulating container 1 further includes wall bodies 11 and 12. The container main body 2, the lid body 3, and the wall bodies 11 and 12 are all molded articles made of polystyrene foam.

  The container body 2 is formed in a rectangular parallelepiped box shape having different lengths in the longitudinal direction L and the width direction B. That is, the container body 2 is integrally formed from the bottom wall 6 and the side walls 7 and 8 erected from the four sides of the bottom wall 6. The side walls 7 face each other in the longitudinal direction L, and the side walls 8 face each other in the width direction B. A rectangular parallelepiped space region (corresponding to a storage region) surrounded by the side walls 7 and 8 serves as a storage unit 9 for storing the fish F. By forming the opening 10 in the upper part of the container body 2, the upper part of the container body 2 is opened.

  The upper outer surface of the container body 2 is formed so as to be recessed inward so as to reduce the thickness (wall thickness) of the side walls 7 and 8. By doing so, a stepped surface having a rectangular frame shape in plan view is formed on the upper outer surface of the container body 2. This stepped surface is formed in parallel with the upper end surface 2a of the container body 2 formed on a flat surface. The stepped surface is used as an outer lid hooking surface 2b on which the outer edge portion of the outer lid 5 is placed.

  The upper inner surface of the container body 2 is formed to be recessed outward so as to reduce the thickness of the side walls 7 and 8. By doing so, a stepped surface having a rectangular frame shape in plan view is formed on the upper inner surface of the container body 2. This stepped surface is formed in parallel with the upper end surface 2 a of the container body 2. The stepped surface is used as an inner lid hooking surface 2c on which an outer edge portion (an inclined surface described later) of the inner lid 4 is placed. The inner lid hanging surface 2c is positioned below the outer lid hanging surface 2b.

  On the outer surfaces of the side walls 7 and 8, gripping recesses 70 and 80 used to lift the cold container 1 by an operator are formed. These holding recesses 70 and 80 are formed so as to cut out the outer surfaces of the side walls 7 and 8 from below to above (to reduce the thickness of the side walls 7 and 8). The upper surfaces 70a and 80a are formed to be lower than the inner lid hooking surface 2c.

The walls 11 and 12 are formed in rectangular plates having different sizes. A groove for partitioning the accommodating portion 9 into a plurality of accommodating regions 13 (or accommodating regions 14) by the wall body 11 (or the wall body 12) is formed in the accommodating portion 9. This groove constitutes a part of installation means capable of installing the wall body 11 (12) in the housing portion 9. The groove of the container body 2 includes a bottom wall groove formed on the bottom wall surface 6 a that forms the housing portion 9, and a side wall groove formed on the side wall surfaces 7 a and 8 a of the side walls 7 and 8 that form the housing portion 9. . Incidentally, partitioning the accommodating portion 9 in the wall 11 (12), fish F accommodated in accommodating part 9 is maintained as much as possible accommodating section in order not to move in the 9 quality (fish F during transport Because).

  The bottom wall groove is composed of a plurality of types (two types in this case) of different usages, that is, a first bottom wall groove 15 and a second bottom wall groove 16. The first bottom wall groove 15 and the second bottom wall groove 16 are formed so as to form a lattice-like aspect in plan view so as to intersect the longitudinal direction L and the width direction B of the container body 2.

  The first bottom wall groove 15 is arranged so that the housing portion 9 can be divided into a plurality of narrow housing regions 13 in the longitudinal direction L by a plurality of wall bodies 11 having the same size. Specifically, the first bottom wall groove 15 is formed on the bottom wall surface 6a by only nine strips (nine pieces), and the first bottom wall grooves 15 are arranged in parallel to each other along the width direction B of the container body 2. ing. Further, the first bottom wall groove 15 extends over the entire width direction B of the bottom wall surface 6 a and reaches the opposing side wall 8 (side wall surface 8 a) of the container body 2.

  As shown in FIG. 3, the second bottom wall groove 16 accommodates the accommodating portion 9 in a plurality of narrow spaces in the width direction B by a plurality of wall bodies 12 (size different from the wall body 11) having the same size. It is arranged so that it can be divided into areas 14. Specifically, the second bottom wall groove 16 is formed in two lines (two) on the bottom wall surface 6a, and the second bottom wall grooves 16 are arranged in parallel with each other along the longitudinal direction L of the container body 2. ing. Further, the second bottom wall groove 16 extends over the entire region in the longitudinal direction L of the bottom wall surface 6a and reaches the opposite side wall 8 (side wall surface 8a) of the container body 2.

  The side wall groove includes a first side wall groove 17 and a second side wall groove 18. The first side wall groove 17 is formed corresponding to each first bottom wall groove 15. That is, the first side wall groove 17 is continuous with the end portion of each first bottom wall groove 15 and is formed along the height direction of the container body 2 over the vertical direction of the side wall surface 8a. The depth of the first side wall groove 17 is set slightly smaller than the width of the inner lid hooking surface 2c.

  The second side wall groove 18 is formed corresponding to each second bottom wall groove 16. That is, the second side wall groove 18 continues to the end of each second bottom wall groove 16 and is formed along the vertical direction of the side wall surface 7a along the height direction of the container body 2. The depth of the second side wall groove 18 is set smaller than the width of the inner lid hooking surface 2c.

  The first bottom wall groove 15 and the second bottom wall groove 16 have the same depth, and the first side wall groove 17 and the second side wall groove 18 have the same depth. Compared with the depth of 16, the depth of the side wall grooves 17 and 18 is set shallower. The depth of the side wall grooves 17 and 18 is determined in relation to the width of the inner lid hanging surface 2c, and is set to be shallower than the width of the inner lid hanging surface 2c. Further, since the holding recesses 70 and 80 are formed on the outer surfaces of the side walls 7 and 8, it is necessary to secure the strength accordingly. For this reason, it is preferable that the depth of the side wall grooves 17 and 18 is set as shallow as possible.

  Next, the configuration of the lid 3 will be described with reference to FIGS. The lid 3 is composed of the inner lid 4 and the outer lid 5 as described above. First, the inner lid 4 will be described. As shown in FIG. 4, the inner lid 4 is formed in a rectangular shape in plan view.

  The inner lid 4 includes a plate-like inner lid main body 20. The inner lid main body 20 is formed in a size that allows position adjustment in the longitudinal direction L and the width direction B with respect to the opening 10 of the container main body 2. That is, the length in the longitudinal direction L of the inner lid body 20 (also the longitudinal direction L of the container body 2) is set slightly smaller than the length in the longitudinal direction L of the opening 10, and the width direction of the inner lid body 20 The length (which is also the width direction of the container body 2) is set slightly smaller than the length of the opening 10 in the width direction. That is, when the inner lid 4 is attached to the container body 2 so as to cover the opening 10, the inner surface (the inner surface in the longitudinal direction L and the inner surface in the width direction B) of the container body 2 and the outer surface of the inner lid 4 (in the longitudinal direction L). A gap δ exists between the outer surface and the outer surface in the width direction B).

  As shown in FIGS. 5 and 6, the lower four sides (corresponding to the peripheral portion) of the inner lid main body 20 are inclined surfaces 21 that are inclined downward toward the inside. The inclined surface 21 is a surface placed on the corner 2d (see FIGS. 1 and 2) of the inner lid hanging surface 2c. When the middle lid 4 has the four sides of the inclined surface 21 placed on the corner 2d of the middle lid hooking surface 2c, the middle portion of the inclined surface 21 contacts the corner 2d. In addition, the four corners of the inner lid body 20 are formed in arcuate surfaces that are convex in the diagonal direction.

  On the lower surface (surface on the accommodating portion 9 side) 20a of the inner lid main body 20, a lid body groove is formed that corresponds (opposites) to the first bottom wall groove 15 and the second bottom wall groove 16 in the vertical direction. . That is, as shown in FIG. 7, the first cover groove 22 and the second cover that form a lattice-like form as viewed from the bottom so that the cover groove intersects the longitudinal direction L and the width direction B of the container body 2. The body groove 23 is constituted. Specifically, the first lid groove 22 is formed over the entire region along the width direction B of the inner lid body 20. The second lid groove 23 is formed across the entire longitudinal direction L along the longitudinal direction L of the inner lid body 20. The first lid groove 22 and the second lid groove 23 are formed at the same depth.

  On the lower surface 20a of the inner lid body 20, guide means for guiding an upper edge portion of the wall body 11 (12), which will be described later, to be easily fitted into the first lid groove 22 and the second lid groove 23 is provided. Yes. The guide means includes guide surfaces 20c and 20d that are inclined toward the first lid groove 22 and the second lid groove 23 on the respective side portions of the first lid groove 22 and the second lid groove 23. ing. Each of these guide surfaces 20c, 20d is formed along the first lid groove 22 and the second lid groove 23 and over the entire length direction of these grooves.

  The installation means capable of installing the wall body 11 (12) in the accommodating portion 9 is composed of the bottom wall groove, the side wall groove, and the lid body groove, and the edge of the wall body 11 (12) It is detachable in the groove.

  The upper surface of the inner lid 4 is formed so that the cold storage material C can be placed over the entire spreading direction. That is, the inner lid body 20 is configured such that a plurality of the regenerator materials C can be placed individually, and a partition wall 26 protruding upward is integrally formed on the upper surface 20 b of the inner lid body 20. . The partition wall 26 is formed in a lattice shape in plan view, with a wall portion 24 extending along the longitudinal direction L of the inner lid body 20 and a wall portion 25 extending along the width direction B. The wall portions 24 and 25 form a cool storage material partition region (corresponding to a cool storage material placement region) 27 including nine locations.

  As described above, the wall portions 24, 25 are erected from the upper surface 20 b of the inner lid body 20, so that a plurality of cold storage material partition regions 27 that can store the cold storage material C are formed so as to drop the upper surface of the inner lid 4. Thus, the cold storage material C can be held (fixed) in the cold storage material partition region 27 by the walls 24 and 25. The height from the upper surface 20b of the inner lid body 20 to the upper end surface 26a of the partition wall 26 is uniform. Moreover, the outer side edge part of the partition wall 26 (wall part 24, 25) is formed in the circular arc surface 24a, 25a which protrudes toward diagonally upward, respectively.

  The wall 24 and the second lid groove 23 extending along the longitudinal direction L are arranged at positions corresponding to the upper and lower sides in the width direction B on the upper surface 20b and the lower surface 20a of the inner lid body 20. On the other hand, the wall 25 extending along the width direction B and the first lid groove 22 are not located at positions corresponding to the upper surface 20 b and the lower surface 20 a of the inner lid body 20.

  The inner lid main body 20 is formed with a cold air supply hole 28 that communicates with the housing portion 9 and causes the cold air C1 (see FIG. 1) from the cold storage material C to drop. The cold air supply hole 28 is formed for each cool storage material partition region 27. In this case, each of the cool storage material partition regions 27 on both sides in the longitudinal direction L is formed with three cold air supply holes 28, and each of the cool storage material partition regions 27 in the center in the longitudinal direction L has two cool air supply holes 28. Is formed. Each of the cold air supply holes 28 is formed as a long hole that is long in the width direction. As the regenerator material C, a water supply polymer that absorbs water and is coated with a nylon / polyethylene film is used.

  The number of cold air supply holes 28 formed in the cold storage material partition regions 27 on both sides of the longitudinal direction L (total area of the holes) is increased with respect to the cold air supply holes 28 formed in the cold storage material partition region 27 in the center in the longitudinal direction L. The reason is that the outside air temperature of the cold container 1 atmosphere is easily transmitted into the container body 2, and the portion of the cold storage container 1 atmosphere is less likely to be transferred into the container body 2 than the cold storage material C. This is because a large amount of cool air C1 can be supplied.

  Next, based on FIG. 8 and FIG. 9, the structure of the outer cover 5 is demonstrated. The outer lid 5 is formed in a rectangular plate shape in plan view. The outer surface of the outer lid 5 is set to be flush with the outer surface of the container body 2. On the bottom surface of the outer lid 5, a recess 5 </ b> A is formed in which a region corresponding to the accommodating portion 9 is recessed upward. Further, a flat rectangular recess 5 </ b> B is formed on the upper surface of the outer lid 5. Furthermore, a fitting portion 5 a having a shape that matches the outer lid hooking surface 2 b of the container body 2 from above is formed on the lower outer edge portion of the outer lid 5. In the state where the outer lid 5 is mounted on the container body 2, the recess 5 </ b> B is set to a depth at which the bottom surface 5 c is separated from the upper end surface 26 a of the partition wall 26 of the inner lid 4.

As described above, the partitioning accommodating portion 9 in the wall 11 (12), fish F accommodated in accommodating part 9, so as not to move as much as possible accommodating portion within 9 during transport, the quality of the fish F It is for maintaining. The cold storage container 1 having the above-described configuration is configured such that the edge of the wall body 11 (12) is fitted into a groove serving as an installation means, and is erected with respect to the bottom wall surface 6a of the storage unit 9, whereby For example, the side part F1 (see FIG. 1) of the fish body F is leaned against the wall bodies 11 and 12, and the abdomen F2 is accommodated with the bottom wall surface 6a side of the accommodation part 9 being accommodated. (Accommodated in the posture of standing fish).

  It is less stressful to the fish F to place the fish in a standing position with the abdomen F2 down (on the bottom side of the containing part 9) than in the containing part with the abdomen F2 lying sideways. It has been known. For this reason, by partitioning the accommodating portion 9 with the wall 11 (12) to form a narrow accommodating area, a fish of a certain size can be accommodated in a standing fish.

  The two types of wall bodies 11 (12) are both formed from rectangular plates having the same thickness and height, but differ only in length. That is, depending on the body length and shape of the fish body F to be accommodated, it is selected whether the accommodating portion 9 is partitioned by the spreading direction in the longitudinal direction L or the spreading direction in the width direction B, and depending on the selected direction, the length It is selected whether to use the short wall body 11 or the wall body 12 having a longer length than the wall body 11 (see FIG. 3 in particular).

  In FIG. 1 and FIG. 2, the case where the accommodating part 9 was partitioned into the some accommodating area | region 13 in the longitudinal direction L is shown. That is, the lower edge (lower edge) of the wall 11 is fitted to the first bottom wall groove 15 and the side edge (side edge) of the wall 11 is fitted to the opposing first side wall groove 17. Yes. Further, the inner lid 4 is installed so as to cover the opening 10, and the upper edge portion (upper edge side) of the wall body 11 is fitted into the first lid groove 22.

  The wall body 11 is inserted from above toward the housing part 9 from the opening 10 of the container body 2, and its side edge is slid into the first side wall groove 17, so that the lower edge of the wall 11 is The bottom wall groove 15 is fitted from above. In a state where the inner lid 4 is not attached, the housing portion 9 can be seen from above, so that the wall body 11 can be easily slid into the first side wall groove 17 and fitted into the first bottom wall groove 15. In this case, the wall body 11 selects the first bottom wall groove 15 (first side wall groove 17) at a position corresponding to the shape (particularly the thickness) of the fish body F to be accommodated, and the accommodating portion 9 as a whole is selected. It is set as the some accommodating area | region 13 divided narrowly compared with the longitudinal direction length.

  By partitioning the accommodating portion 9 in this manner, the abdomen F2 can be accommodated with the abdomen F2 facing the bottom wall surface 6a of the accommodating portion 9 so that the side portion F1 of the fish F is leaned against the wall 11. In addition, it is preferable that the fish body F accommodated in the accommodation area | region 13 is made to fall in the preliminarily dead state (inactive state) previously that temperature is reduced.

  Subsequently, the inner lid 4 is put on the opening 10 of the container body 2. Then, the wall body 11 becomes invisible to the operator. For this reason, it becomes difficult to smoothly fit the upper edge portion of the wall body 11 into the first lid groove 22. However, in this cold storage container 1, the guide surface 20 c is formed on the lower surface 20 a of the inner lid body 20 as guide means for guiding the upper edge portion of the wall body 11 to be easily fitted into the first lid groove 22. . Moreover, the length L in the longitudinal direction of the inner lid body 20 is set slightly smaller than the length L in the longitudinal direction of the opening 10, and the length B in the width direction of the inner lid body 20 is the width of the opening 10. It is set slightly smaller than the length in the direction B. That is, the position of the inner lid 4 can be adjusted in the longitudinal direction L and the width direction B with respect to the opening 10.

  For this reason, by covering the inner lid 4 so as to be attached to the opening 10, even if the wall 11 becomes invisible to the operator, the upper edge of the wall 11 while finely adjusting the inner lid 4 in the longitudinal direction L. Is guided to the guide surface 20c, so that the upper edge of the wall 11 can be securely fitted into the first lid groove 22, and the wall 11 is in a standing position with respect to the bottom wall surface 6a. can do. Further, since the lower four sides of the inner lid body 20 are inclined surfaces 21 inclined downward toward the inside, when the inner lid 4 is finely adjusted in the longitudinal direction L, the inclined surfaces 21 slide on the corners 2d. It is easy to fit the upper edge of the wall 11 into the first lid groove 22.

  Further, by covering the opening 10 of the container body 2 with the inner lid 4, the wall body 11 (or the wall body 12) becomes invisible to the operator so that the first lid groove 22 matches the upper edge of the wall body 11. When it is difficult to attach the inner lid 4 to the container main body 2 so that the inner lid 4 can be attached to the container, the outer lid 4 is formed on the arcuate surfaces 24a and 25a using the outer end of the partition wall 26 of the inner lid 4. It can be easily attached to the main body 2. That is, by using the arc surfaces 24a and 25a, the inner lid 4 is tilted with respect to the container body 2 to adjust the first lid groove 22 to coincide with the upper edge of the wall body 11, The lid 4 can be attached to the container body 2. When the outer end portion of the partition wall 26 is formed at a right angle, the outer end portion of the partition wall 26 contacts the side wall surfaces 7 a and 8 a of the side walls 7 and 8 even if the inner lid 4 is inclined with respect to the container body 2. End up. For this reason, the above adjustment cannot be performed.

  When the inner lid 4 is attached to the opening 10, the lower surface 20 a of the inner lid main body 20 slightly enters the upper portion of the housing portion 9. By associating the container body 2 and the inner lid 4 in this manner, the upper edge of the wall 11 can be fitted into the first lid groove 22. That is, the inner lid 4 supports the wall body 11 at its upper part by bringing the wall body 11 into contact (fitting in this case) with its upper edge. When the inner lid 4 is installed on the container body 2, the upper end surface 26 a of the partition wall 26 is configured to be positioned below the upper end surface 2 a of the container body 2.

  Subsequently, one of the cool storage material partition regions 27 is selected according to the number of fish bodies accommodated, and the cool storage material C is placed in the selected cool storage material partition region 27. Since a plurality of cool storage material partition regions 27 are formed, the cool storage material C is installed in the cool storage material partition region 27 corresponding to the storage region 13 in which the fish F is stored. If it does so, the cold air C1 may fall from the cold air supply hole 28 of the cold storage material partition area | region 27 which installed the cold storage material C to the accommodation area | region 13 which accommodated the fish body F (cold air C1 is supplied).

  Subsequently, the outer lid 5 is placed so that the fitting portion 5 a which is the outer edge portion thereof is fitted to the outer lid hooking surface 2 b of the container body 2. Then, the inner lid 4 is covered with the outer lid 5, the flow of air is blocked between the outside air and the inside of the housing portion 9, and the cold air C <b> 1 is sealed. Then, the cold air C1 continues to fall into the accommodation area 13, and the convection of the cold air C1 occurs in the accommodation area 13. It is also preferable that the cold-insulated container 1 that has been fitted with the outer lid 5 is sealed by sticking an adhesive tape (not shown) or the like to the mating surface between the container body 2 and the outer lid 5 from the outside.

  In the cold insulation container 1, the fish body F is not directly cooled using ice or cold water, but indirectly cooled by dropping the cold air C1 from the cold storage material C onto the fish body F. For this reason, it is possible to prevent the fish body temperature from changing abruptly by rapidly cooling the fish body F, and the fish body F can be maintained as a live fish (maintained in a tentative state) without using water. It can suppress that the quality (commercial value) of the fish body F falls.

  Moreover, the whole inside of the accommodating part 9 can be kept cold uniformly by selecting arrangement | positioning of the cool storage material C according to the accommodation state of the fish body F. FIG. In addition, by selecting the arrangement (number) of the regenerator materials C in consideration of the outside air temperature, the entire housing portion 9 can be kept cool while responding to changes in the outside air temperature. Can be reliably suppressed.

  In the case where the housing portion 9 is partitioned in the width direction B to form a plurality of housing regions 14, the wall body 12 having a length longer than that of the wall body 11 is used, and the side edge of the wall body 12 is formed in the second side wall groove 18. The lower edge of the wall 12 is fitted into the second bottom wall groove 16 so as to slide. When the opening 10 is covered with the inner lid 4, the upper edge of the wall body 12 can be easily formed into the second lid groove 23 by finely adjusting the inner lid 4 in the width direction B in the same manner as described above. Can be fitted.

  Anyway, according to the structure of the said embodiment, the abdominal part F2 of the fish body F can be accommodated in the bottom wall surface 6a side of the accommodating part 9, and the stress given to the fish body F can be suppressed. As a result, it is possible to maintain the assassination state of the fish F for a desired time. If so, the fish body F can be transported from the landing site to the destination as live fish. Or without using water, the fish body F can be left in a predetermined place as a live fish.

  Even if the standing fish body collapses due to vibration during the transport of the cold container 1, since the stress applied to the fish body can be suppressed at least while the standing fish body is maintained, the quality of the fish body F is maintained accordingly. can do.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. FIG. 10 shows a second embodiment. This is a cold storage container 1 having a configuration in which the container main bodies 2A and 2B can be stacked in two stages. The second embodiment is different from the first embodiment in that the container main bodies 2A and 2B can be stacked in two upper and lower stages, the outer cover 5 is one piece, The bottom wall 6 of the container main body 2A has a function of an outer lid in the lower container main body 2B.

  That is, a frame-shaped fitting recess 30 into which the upper end portion of the lower container body 2B is fitted is formed on the outer peripheral portion of the lower surface of the upper container body 2A. The fitting recess 30 is formed so that the outer peripheral portion of the lower surface of the upper container body 2A is recessed upward. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and the description thereof is omitted.

  According to the cold insulation container 1 of the second embodiment, more fish bodies F can be conveyed together than the cold insulation container of the first embodiment. In addition, since the outer lid 5 can also be used as the lower container body 2B, when the upper container body 2A or the lower container body 2B is not required, either one is omitted and the fish body F is removed. It can be transported or placed in place. In addition, since the bottom wall 6 of the upper container body 2A has a function of an outer lid in the lower container body 2B, the material cost is lower than when the same cold storage containers 1 are stacked in two stages. become.

  FIG. 11 shows still another embodiment. This is different from the first embodiment and the second embodiment in the cross-sectional shape of the wall body 11 (or the wall body 12). Since some fish bodies F are heavy, the wall 11 (12) of FIG. 11 has a portion that does not fit in the groove thicker than the groove. By using such a wall body 11 (12), even if a heavier fish body F leans against the wall body 11 (12), the wall body 11 (12) is not damaged, and the abdominal part F2 of the fish body F Can be accommodated on the bottom wall surface 6a side of the accommodating portion 9.

  Furthermore, in each said embodiment, the bottom wall groove | channel and the cover body groove | channel were arrange | positioned so that it may cross | intersect at right angles in a longitudinal direction and the width direction. However, the crossing angle between these grooves is not limited to a right angle. Even if the fish are of the same species, their body is not uniform. For example, the planar shape of a fish body is not uniform. Therefore, by standing the wall against the bottom wall so as to follow the planar shape of the fish to be handled, it is possible to protect the fish from vibration and maintain the quality even if there is vibration during transportation of the fish. It is done. For this reason, this becomes possible by setting a groove | channel to the crossing angle which can arrange | position the wall body imitating the planar shape of the fish body to handle to an accommodating part.

  Alternatively, instead of standing the wall against the bottom wall so as to follow the planar shape of the fish body to be handled, it is possible to follow the planar shape of the fish body to be handled by using a wall body with varying width (thickness) It is.

  Moreover, in each said embodiment, in order to stand a wall body with respect to a bottom wall surface, the bottom wall groove | channel, the side wall groove | channel, and the cover body groove | channel were formed and used. However, if the wall body is securely raised with respect to the bottom wall surface and does not move the fish body greatly during transportation, for example, only the bottom wall groove may be formed and the lower edge of the wall body may be fitted thereto. . Further, only the side wall groove may be formed without forming the bottom wall groove, and the side edge portion of the wall body may be fitted thereto. Furthermore, without forming a groove in the inner lid, the posture of the wall body can be supported by pressing the upper edge of the wall body downward by the lower surface of the inner lid. Furthermore, as long as the posture of the wall body can be maintained, the wall body does not necessarily need to contact all of the bottom wall surface, the side wall surface, and the lower surface of the inner lid.

  Moreover, in each said embodiment, it was set as the structure which forms a groove | channel in a container main body or an inner lid as an installation means which can install a wall body. However, as an installation means, a groove is formed at the edge of the wall body, and a convex body that fits into the groove is formed on the container body or the inner lid, so that the wall body stands up against the bottom wall surface. You can also In some cases, the installation means may be used as an adhesive, and the wall body may be raised with respect to the bottom wall surface by the adhesive.

  Furthermore, in each said embodiment, although the inner lid was made into the structural requirements as a cover body, if an external temperature is the temperature which can maintain the assassination state of a fish only for the required time, an inner lid will be abbreviate | omitted and a cool storage material will be used. The fish can be transported or installed in a predetermined place.

  Moreover, although each said embodiment demonstrated how to use the cold storage container for a kind of fish as an example, it is not limited to this. That is, the use of partitioning the storage portion with the wall body according to the number and size of the fish to be stored to secure a necessary storage area, selecting the cold storage material partition area according to the case, and placing the cold storage material it can. Therefore, the number of the cool storage material partition regions is not limited to the above embodiment, and it is conceivable to form more cool storage material partition regions. The number, shape, and arrangement of the cold air supply holes formed in the cold storage material partition region are the same.

  Furthermore, in each said embodiment, while the upper edge part of the wall body 11 or the wall body 12 is fitted to the 1st cover body groove | channel 22 or the 2nd cover body groove | channel 23, the inclined surface 21 of the inner cover 4 is formed. It was configured to be placed on the inner lid hanging surface 2c (corner portion 2d). However, the present invention is not limited to this. For example, as shown in FIG. 12, the wall 11 or the upper edge of the wall 12 abuts the bottom surface of the first lid groove 22 or the second lid groove 23, so that the inclined surface of the inner lid 4 It is also possible to cover the opening 10 with the inner lid 4 so that 21 slightly floats from the inner lid hanging surface 2c. In this case, the inner lid 4 moves in the longitudinal direction L or the width direction B, and the outer surface of the inner lid 4 abuts against the inner surface of the container body 2, so that the gap δ is filled. Therefore, the wall 11 or the wall 12 can be supported by the upper edge portion.

  In this way, the upper edge of the wall body 11 or the wall body 12 abuts against the bottom surface of the first lid groove 22 or the second lid groove 23 so that the inclined surface 21 of the inner lid 4 is hooked on the inner lid. In the configuration in which the opening portion 10 is covered with the inner lid 4 so as to float slightly from the surface 2c, the inner lid 4 is attached to the opening portion 10 by placing the inclined surface 21 of the inner lid 4 on the inner lid hanging surface 2c. Compared with the case where it does, it is easy to mount | wear the opening part 10 with the inner cover 4. FIG.
