According to this aspect, when the lid is attached to the container main body, the front end portion of the support column extending from the bottom surface of the container main body can be easily fitted to the inner surface of the lid by the fitting portion. . Further, when the liquid is stored in the container body, the buoyancy of the support column due to the liquid does not directly act on the lid, and therefore it is easy to maintain the fitting between the cover and the container body (support column).

  Furthermore, as a more preferable aspect in which a fitting portion is provided, a hollow portion is formed in the column portion, and a column opening portion is formed at the tip portion of the column portion so that an upper portion of the cavity portion is opened. The fitting portion is formed so as to sandwich a strut inner wall surface forming the strut opening and a strut outer wall surface of the strut portion at the tip end portion of the strut portion.

  According to this aspect, using the hollow part formed in the support | pillar part, for example, a cold insulating agent, crushed ice, etc. can be put, and the temperature control inside the container for transport can be performed. In addition, the fitting portion provided on the inner surface of the lid body is fitted to the column portion so as to sandwich the column inner wall surface that forms the column opening and the column outer wall surface of the column portion, so the lid body and the container body And the fitting can be made stronger.

  As a more preferable aspect, a partition wall that divides the housing space into a plurality of divided spaces is formed between the support column and the side wall of the container body. According to this aspect, since the accommodation space is separated by the partition wall and a plurality of divided spaces can be formed in the transport container, water or seawater is accommodated in the divided spaces, and live fish is contained in each divided space. Can be accommodated.

  Here, if the partition space can be formed by forming the partition wall between the support column and the side wall of the container body, the partition wall extends from the sidewall to the support column. Also good. However, as a more preferable aspect, the partition wall portion extends from the support column portion toward the side wall portion of the container body. Thus, by forming the partition wall from the support column toward the side wall of the container body, the rigidity of the support column can be further increased.

  Furthermore, as a preferable aspect in which the partition wall portion extends from the support column portion, the partition wall portion extends toward the corner portion of the side wall portion of the container main body. According to this aspect, since the partition space is formed by extending the partition wall portion from the support column portion toward the corner portion of the side wall portion of the container body, live fish can be accommodated in the partition space.

  Here, each divided space divided by the partition wall may be a completely independent space. However, as a more preferable aspect, a communication portion that connects the divided spaces is formed in the transport container. Has been. According to this aspect, since the divided spaces are communicated with each other by the communication portion, the divided spaces can be passed through when water is accommodated in each divided space. Thereby, local deterioration of water quality can be suppressed.

  The transport container according to the present embodiment is a container for storing fresh products such as seafood and vegetables as packed items and transporting them. The transport container 10 is made of foamed resin, such as polystyrene, styrene modified polyolefin resin, high impact polystyrene, styrene-ethylene copolymer, styrene-maleic anhydride copolymer, styrene-acrylonitrile copolymer, and the like. Various synthetic resin foams such as polystyrene resin, polyolefin resin such as polyethylene, polypropylene, and ethylene-vinyl acetate copolymer, and polyester resin such as polyethylene terephthalate can be used.

  Among these, a molded body by bead foaming of polystyrene or styrene-modified polyolefin resin is preferably used. The styrene-modified polyolefin resin is obtained by impregnating and polymerizing a polyolefin resin particle with a styrene monomer. Among the styrene-modified polyolefin resins, a styrene-modified polyethylene resin is preferable, for example, a styrene component The ratio is 40 to 90% by weight, preferably 50 to 85% by weight, more preferably 55 to 75% by weight.

  Further, the expansion ratio of the polystyrene foam is preferably 30 to 80 times. The foamed resin used in the transport container 10 of the present embodiment has a higher foaming ratio than the conventional one. By increasing the expansion ratio in this way, the structure is more easily crushed and has an excellent buffering effect when a load is applied compared to the conventional expansion ratio.

  As shown in FIG. 1, the container 10 for transport covers the container main body 20 in which the opening part 20a was formed so that the upper part of the accommodation space S might open, and the opening part 20a of the container main body 20, and formed the opening part 20a. And a lid body 30 fitted to the opening edge portion 20d.

  The container body 20 has a square shape when viewed from above, and an opening 20a is formed by four side walls 21 rising from the square bottom wall 22 so that the upper portion of the accommodation space S is opened. In the present embodiment, the container body 20 has a square shape when viewed from above, but the shape is not particularly limited, such as a rectangle, a circle, or an ellipse.

  On the opening edge portion 20d that forms the container body 20, a fitting protrusion 24 that fits with the fitting groove 34 formed on the inner surface 30b of the lid 30 shown in FIG. 3 is formed. Accordingly, the fitting groove 34 of the lid 30 is fitted to the fitting protrusion 24 of the opening edge 20d in a state where the opening 20a of the container main body 20 is covered with the lid 30, and the container main body 20 is fitted with the fitting groove 34. The lid 30 can be fitted.

  On the outer surface of the side wall portion 21 of the container body 20, a lightening portion 26 in which a part of the side wall portion 21 is thinned is formed from the bottom wall portion 22 of the container body 20 upward. By providing the lightening portion 26, the container body 20 can be reduced in weight, and the upper edge portion of the lightening portion 26 can be used to easily lift and transport the container main body 20 (transport container 10).

  As shown in FIG. 2, a stepped portion 23 is formed on the peripheral edge of the outer bottom surface 20 c of the container body 20. Specifically, when the transport containers 10 are stacked in the vertical direction, the stepped portion 23 of the upper transport container 10 is formed on the upper surface 30a of the lid 30 of the lower transport container 10. A stepped portion 23 is formed so as to engage with the letter-shaped engaging convex portion 39.

  Thus, the engaging projection 39 on the upper surface 30a of the lid 30 and the stepped portion 23 formed on the bottom wall portion 22 of the container body 20 are positioning portions for stacking the transport containers 10 in the vertical direction. Acts as

  The transport container 10 has a lid body from the center of the bottom surface 20b of the container body 20 forming the accommodation space S in a state where the lid body 30 is fitted to the fitting protrusion 24 of the opening edge 20d of the container body 20. A columnar column portion 25 that extends over the center of the inner surface 30 b of the 30 and supports the lid body 30 is formed.

  Specifically, the support column 25 is formed integrally with the bottom surface 20 b of the container body 20 so as to extend from the bottom surface 20 b of the container body 20 toward the inner surface 30 b of the lid body 30. A support surface 25a, which is a tip surface of the support column 25, has a circular shape and supports the inner surface 30b of the lid 30 (see, for example, FIG. 4).

  On the other hand, as shown in FIG. 3, the inner surface 30b of the lid 30 is fitted to the tip 25c of the support column 25 (specifically, a part of the side surface 25b of the support column 25 forming the tip 20c). The fitting part 35 to be formed is formed. The fitting portion 35 protrudes from the inner surface 30b of the lid 30 so that the tip end surface 35a has a ring shape, and the inner peripheral surface 35b of the fitting portion 35 forms a tip portion 25c of the column portion 25. 25 is fitted to a part of the side surface 25b.
