Description

  The present invention relates to a cold insulated container made of a synthetic foam resin used when transporting large fish such as tuna and yellowtail.

  For example, when transporting large fish such as tuna and yellowtail in the cold state, a cold insulated container made of foamed synthetic resin is used. As such a cold container, a large fish box disclosed in Patent Document 1 is known. This large fish box has a pair of left and right ribs with a fixed width projecting inward in the left-right direction of the box body at the front and rear portions of the left and right side walls of the box body. The ribs sandwich a part of the large fish from the left and right within the box body.

Japanese Utility Model Publication No. 58-41193

  However, in the large fish box, since the contact surface of the rib with the large fish is a plane along the longitudinal direction of the box body, the contact surface of the rib is difficult to follow the curved fish body shape of the large fish. The shift movement of the box body in the front-rear direction cannot be sufficiently prevented. For this reason, for example, a large fish may be displaced in the front-rear direction of the box body during the transportation process or the like, and its head or tail may hit the front and rear side walls of the box body. In this way, when the head or tail of a large fish hits the front and rear side walls of the box body, the hardness of the foamed synthetic resin that is the material of the box body is low, while the head or tail of the large fish is sharp, the box There is a problem that cracks occur on the front and rear side walls of the main body, and the side walls may be damaged. In addition, in the large fish box, a part of the large fish is held in a state where it is in contact with the edge of the rib at a point or a line, so when the large fish stored in the raw state tries to move in the front-rear direction In addition, a part of the large fish is strongly pressed by the edge of the ribs, resulting in great damage, and there is a risk that the commercial value of the large fish is impaired.

  The present invention has been made in view of the above-described problems. For example, in a transportation process, the large fish housed therein can be prevented from shifting in the front-rear direction, and the damage to the large fish can be suppressed. The purpose is to provide a cold container.

  In order to achieve the above-described object, the cold storage container of the present invention is a cold storage container for storing a large fish made of foamed synthetic resin, and the fish fixing portion is located at a position where the large fish is stored inside the cold storage container. The portion where the large fish comes into contact with the fish fixing portion has a surface that is inclined so that the center side in the front-rear direction of the cold storage container is lowered. As a result, the large fish is caught in a state in which the portion in contact with the fish fixing portion is in contact with the inclined surface of the fish fixing portion, so that when the large fish tries to move in the front-rear direction, the large fish The movement in the direction can be suppressed to prevent the large fish from shifting in the front-rear direction, and the damage to the large fish can also be suppressed.

  Moreover, in the cold storage container of this invention, the said fish fixing | fixed part is provided before and behind in the inside of the said cold storage container. Thereby, since the large fish is caught in a state where the part contacting the front and rear fish fixing parts is in contact with the inclined surface of the front and rear fish fixing parts on the surface, when the large fish tries to move in the front and rear direction, The large fish can be prevented from moving in both the front and rear directions to prevent the large fish from shifting in both the front and rear directions, and can also prevent damage to the large fish.

  Moreover, in the cold storage container of this invention, the said fish fixing | fixed part is provided up and down in the inside of the said cold storage container. Thereby, the large fish is caught in a state where the upper and lower fish fixing portions are in contact with the inclined surfaces of the upper and lower fish fixing portions, so when the large fish tries to move in the front-rear direction, The large fish can be prevented from moving in the front-rear direction to prevent the large fish from shifting in the front-rear direction, and can also prevent damage to the large fish. In addition, in this case, since the large fish is prevented from moving in the vertical direction by the upper and lower fish fixing portions, it is possible to prevent the large fish from moving in the vertical direction while preventing the large fish from shifting in the front-rear direction.

  Moreover, in the cold storage container of this invention, the said fish fixing | fixed part is provided so that the perimeter of a large sized fish may be enclosed inside the said cold storage container. As a result, the large fish is caught in a state where the entire circumference is in contact with the inclined surface of the fish fixing portion, so that the catching force on the large fish increases, and when the large fish tries to move in the front-rear direction, the large fish The movement in the front-rear direction is further suppressed, and the displacement movement of the large fish in the front-rear direction can be prevented more reliably.

  Moreover, in the cold storage container of this invention, the said fish fixing | fixed part is provided in the position which opposes the up-down direction of the said cold storage container. As a result, the large fish is caught while the upper and lower opposing portions are in contact with the inclined surfaces of the upper and lower fish fixing portions, so that the catching force of the fish fixing portion against the large fish increases, and the large fish moves in the front-rear direction. When attempting to move, the large fish is further restrained from moving in the front-rear direction, and the large fish can be more reliably prevented from shifting in the front-rear direction.

  Moreover, in the cold storage container of this invention, the said fish fixing | fixed part is provided in the position which shifted | deviated to the front-back direction of this cold storage container in the up-down direction of the said cold storage container. As a result, the large fish catches in the state where the upper and lower fish-fixing portions are in contact with the inclined surfaces of the upper and lower fish-fixing portions so that the fish-fixing portion catches the large fish. When the force increases and the large fish tries to move in the front-rear direction, the large fish is further restrained from moving in the front-rear direction, and the large fish can be more reliably prevented from shifting in the front-rear direction.

  In the cold storage container of the present invention, as the fish fixing part, a fixing member formed separately from the cold storage container is provided at a position where a large fish is accommodated inside the cold storage container. Thereby, a cold storage container can be made into a simple structure and manufacture of this cold storage container can be performed easily.

  Further, the cold storage container of the present invention comprises a box-shaped container main body having an open upper surface and an upper lid that is detachably attached to the upper end of the container main body, and the container main body accommodates a large fish. A lower fixing rib is formed along the left-right direction of the container main body in a state of protruding from the bottom wall at a position where the lower end of the container main body is lowered. The upper lid is formed with an upper fixing rib along the left-right direction of the upper lid in a state protruding from the top wall, and is formed at the lower end of the upper fixing rib. The fitting part which has the surface which inclines so that it may become low in the center side of the front-back direction of this upper cover is formed. Thus, when the large fish is accommodated in the container main body and the upper lid is attached to the container main body, the portion of the large fish that contacts the lower fixing rib and the upper fixing rib of the upper lid is the lower fixing rib and the upper fixing rib. When the large fish tries to move in the front-rear direction when it is caught in contact with the inclined surface of the fitting part of the fixing rib, the movement of the large fish in the front-rear direction is suppressed. It can prevent shifting and can also prevent damage to large fish.

  Furthermore, the cold storage container of the present invention includes a pair of box-shaped container members whose upper surfaces are open, and the container members protrude from the bottom wall at a position where a large fish is accommodated in the left-right direction of the container member. A lower fixing rib is formed along the upper end of the lower fixing rib. The lower surface of the lower fixing rib is curved in an arc shape in the vertical direction of the container member, and is inclined so as to be lowered toward the center in the front-rear direction of the container body. The fitting part which has is formed. Thereby, when the large fish is caught in a state where the portion that contacts the fixing rib of the container member is in contact with the inclined surface of the fitting portion of the fixing rib on the surface, and the large fish tries to move in the front-rear direction, The large fish can be prevented from moving in the front-rear direction to prevent the large fish from shifting in the front-rear direction, and can also prevent damage to the large fish. In addition, since the cold insulation container can be formed by turning one side upside down so that the openings face each other so that the openings face each other, the container can be formed with one kind of container member, and the manufacturing cost can be rationalized. At the same time, inventory management is easy.

  According to the cold storage container of the present invention, since the large fish housed therein does not shift and move in the front-rear direction, the sharp head or tail of the large fish hits and the side wall is damaged and the like is prevented. The reliability can be improved and the commercial value of the large fish can be maintained by suppressing damage to the large fish.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings.

  FIG. 1 shows a rectangular parallelepiped cold storage container 1 for accommodating a large fish (eg, tuna, yellowtail, etc.) M according to the present invention. The cold storage container 1 includes a container main body 10 that accommodates a large fish M, and an upper lid 20 that is detachably attached to the upper end of the container main body 10.

In addition, since the fitting part 15a of the rear lower fixing rib 15 fixes the tail part of the large fish M, the fitting part 14a of the front lower fixing rib 14 that fixes the head of the large fish M is provided. Compared to, the diameter of the arc and the gradient of the inclination are made smaller.

  As shown in FIG. 3, the upper lid 20 is a rectangular box whose depth is shallower than that of the container body 10 having an open bottom surface, and is formed in a size corresponding to the container body 10. The top lid 20 has a rectangular ceiling wall 21, left and right long side walls 22, 22 suspended opposite to both side edges of the ceiling wall 21, and suspended opposite to both end edges of the ceiling wall 21. It is formed in the box by the short side walls 23 and 23 provided before and after. On the top wall 21 of the lid 20, upper fixing ribs 24 and 25 having a constant width are provided in parallel along the left-right direction of the upper lid 20 at a distance from the front and back of the lower surface.

  The upper fixing ribs 24 and 25 are for fixing the upper surface side of the large fish M, and when the upper lid 20 is attached to the container main body 10, the front (left side in the drawing) upper fixing rib 24 is the container main body. 10 is located at a position corresponding to the tail of the large fish M accommodated in the container body 10 at a position corresponding to the head of the large fish M accommodated in the container 10. As described above, the upper lid 20 is provided at an asymmetrical position when viewed from the center in the front-rear direction and at a position deviated from the lower fixing ribs 14 and 15 of the container body 10 toward the center in the front-rear direction.

  The upper fixing ribs 24, 25 protrude from the top wall 21 of the upper lid 20, and the left and right directions of the upper lid 20 so that the lower ends are somewhat higher than the lower ends of the side walls 22, 22 and 23, 23 of the upper lid 20. And both sides thereof are connected to the long side walls 22 and 22 through the left and right long side walls 22 and 22.

  The front upper fixing rib 24 has a concave fitting portion 24a that can be fitted to the head of the large fish M at the center of the lower end. This fitting part 24a is formed in the taper-shaped circular arc surface which becomes a large diameter gradually toward the center side of the front-back direction of the upper cover 20 so that the head of the large fish M may be followed. That is, the fitting portion 24 a of the front upper fixing rib 24 is formed in an arcuate surface that is inclined so that the center side in the front-rear direction of the upper lid 20 is lowered and is curved in the vertical direction of the upper lid 20.

  The rear upper fixing rib 25 is formed with a concave fitting portion 25a that can be fitted to the tail portion of the large fish M at the center of the lower end. This fitting part 25a is formed in the taper-shaped circular arc surface which becomes a large diameter gradually toward the center side of the front-back direction of the upper cover 20 so that the tail part of the large fish M may be followed. That is, the fitting portion 25a of the rear upper fixing rib 25 is formed in a circular arc surface that is inclined so that the center side in the front-rear direction of the upper lid 20 is lowered and is curved in the vertical direction of the upper lid 20. Accordingly, the fitting portion 25a of the rear upper fixing rib 25 is formed so that the inclined surface faces the fitting portion 24a of the front upper fixing rib 24. Since the fitting portion 25a of the rear upper fixing rib 25 is fitted to the tail portion of the large fish M, the fitting portion 24a of the front upper fixing rib 24 to be fitted to the head of the large fish M is provided. Compared to, the diameter of the arc and the gradient of the inclination are made smaller.

  On the lower end surface of the upper lid 20 (the lower end surfaces of the left and right long side walls 22, 22 and the front and rear short side walls 23, 23), a fitting ridge portion 26 that fits the fitting ridge portion 16 of the container body 10 is provided. It has been. The fitting ridge 26 is formed to protrude downward on the outer edge of the lower end surface of the upper lid 20 over the entire circumference. The upper lid 20 is detachably attached to the upper end of the container body 10 in a sealed state by fitting the fitting protrusions 26 to the fitting protrusions 16 of the container body 10.

  In order to transport the large fish M using the cold storage container 1, the large fish M is accommodated inside the container body 10. At that time, the head of the large fish M is placed in a state of being fitted to the fitting portion 14a of the front lower fixing rib 14, and the tail of the large fish M is placed on the rear lower fixing rib. It mounts in the state fitted to 15 fitting parts 15a. In this case, the portion of the large fish M that contacts the fitting portions 14a and 15a of the lower fixing ribs 14 and 15 abuts the inclined surfaces of the fitting portions 14a and 15a of the lower fixing ribs 14 and 15 on the surface. The large fish M is restrained from moving in the front-rear direction, and the large fish M is in contact with the surface, so that damage to the large fish M can be suppressed. Moreover, since the fitting portions 14a and 15a of the lower fixing ribs 14 and 15 are formed to face each other so that the center side in the front-rear direction of the container body 10 is lowered, the large fish M is arranged in the front-rear direction. Both shift movements can be prevented.

  Next, when the upper lid 20 is attached to the upper end of the container body 10, the fitting portions 24 a and 25 a of the upper fixing ribs 24 and 25 suspended from the top wall 21 of the upper lid 20 are fitted to the upper surface of the large fish M. The portion of the large fish M that contacts the fitting portions 24a, 25a of the upper fixing ribs 24, 25 of the upper lid 20 of the head and tail is the fitting portions 24a of the upper fixing ribs 24, 25 of the upper lid 20. The large fish M will be caught in a state of being in contact with the inclined surface of 25a, and the movement of the large fish M in the front-rear direction can be further suppressed, so that the large fish M can be prevented from shifting in the front-rear direction more reliably.

  According to the cold storage container 1, the large fish M is accommodated in the container main body 10, and the upper lid 20 is attached to the container main body 10. Since the hooks 14 and 15 of the fixing ribs 14 and 15 and the upper fixing ribs 24 and 25 of the upper lid 20 are hooked in contact with the inclined surfaces of the fitting parts 24a and 25a, the large fish M moves forward and backward. When the large fish M is moved in the direction, the large fish M is restrained from moving in the front-rear direction to prevent the large fish M from moving in the front-rear direction, and the large fish M is in contact with the surface, so the large fish Damage to M can be suppressed. Therefore, since the large fish M accommodated in the inside does not shift in the front-rear direction, the sharp head or tail of the large fish M hits the short side walls 13, 13 of the container body 10, and the side wall No inconveniences such as breakage of 13, 13 occur. And since the damage to the large fish M is suppressed, the commercial value of the large fish M can be maintained.

  Moreover, since the lower fixing ribs 14 and 15 of the container body 10 are integrally formed on the bottom wall 11 and the left and right long side walls 12 and 12, the cold insulation container 1 has the lower fixing ribs 14 and 15. The bottom wall 11 and the left and right long side walls 12 and 12 of the container body 10 are reinforced, and deformation of the bottom wall 11 of the container body 10 and the long left and right side walls 12 and 12 due to the weight of the large fish M can be prevented.
