Description

  The present invention relates to a transport container for seafood for transporting seafood in an active state.

  Such a seafood transport container is formed of a foamable synthetic resin, and includes a container main body and a lid body in which a seafood storage section for storing water and seafood and an air pump storage section for storing a pump are separated by a vertical wall. It is comprised so that air may be supplied to the water in a seafood accommodation part from the air disperser which is equipped and is connected to the pump via the air tube (for example, refer patent document 1).

  The seafood transport container of Patent Document 1 transports seafood while increasing the dissolved oxygen content of water in the seafood container by supplying air from an air disperser. However, if transported on a hot summer day, the water temperature in the seafood container will rise rapidly. When the water temperature rises rapidly, the water in the seafood container is drowned rapidly by the discharge from the seafood. Moreover, when the water temperature rises, the amount of dissolved oxygen required by the seafood also decreases as compared to the low temperature, so the activity of the seafood becomes very poor and the survival rate of the seafood becomes very low. There was an inconvenience.

  In order to suppress the rise in the water temperature as described above, an inner lid on which ice can be placed is provided at the upper end of the container body, and ice cold air is supplied to the water below from the vent hole formed in the inner lid. (See, for example, Patent Document 2).

And front and rear side walls 8 and 9 erected upward from the front and rear edges. And the opening 2A for taking in and out water and seafood is formed in the upper part of these four side walls 6,7,8,9. Moreover, the notch K recessed inside is formed in the right-and-left center of the front and back side walls 8 and 9, and the transport container 1 for seafood can be lifted by hooking a finger on the upper surface of the notch K.

  In addition, a vertical wall 12 is formed in the container body 2 to separate a seafood container 10 for storing water and seafood and two air pump storage parts 11, 11 for storing an air pump (not shown). Has been. That is, two air pump accommodating portions 11, 11 are formed between the front side wall 8 and the vertical wall 12. And two air pump accommodating parts 11 and 11 are arrange | positioned at the left-right direction both ends, and by arrange | positioning the ice accommodating part 13 which accommodates ice in the left-right direction center part between these two air pump accommodating parts 11 and 11, two The air pump accommodating portions 11 and 11 and the ice accommodating portion 13 are arranged in a line in the left-right direction. In this way, if the two air pump accommodating portions 11, 11 and the ice accommodating portion 13 are arranged in a line in the left-right direction, the three accommodating portions 11, 11, 13 are efficiently arranged in one place. can do.

  The vertical wall 12 is set to a length that connects one end portions (front end portions) of the left and right side walls 6 and 7 facing each other, and the seafood container 10 includes the bottom wall 4, the vertical wall 12, and the three side walls. It consists of certain left and right side walls 6, 7 and a rear side wall 9. The inner surface 12A of the vertical wall 12 is formed on a smooth flat surface without unevenness. Thus, if the vertical wall 12 is formed on a smooth surface without irregularities, the water that has moved from the opening 12K of the vertical wall 12 can be moved smoothly in the seafood container 10.

  An opening 12 </ b> K for communicating the seafood container 10 and the ice container 13 is formed at the center of the vertical wall 12 in the left-right direction. The opening 12K is formed in a slit shape that is long in the vertical direction and is formed from the lower end of the vertical wall 12 (above the upper surface 4A of the bottom wall 4) to the upper end. By configuring the opening 12K in the shape of a slit that is long in the vertical direction, the amount of movement of the melted water of the ice stored in the ice storage section 13 into the seafood storage section 10 is accurately limited, and the seafood storage Not only can the water temperature in the section 10 be lowered gradually, but the melted ice can be evenly moved over a wide range in the vertical direction.

  The ice storage portion 13 has a rectangular shape that is long in the left-right direction in a plan view and is also long in the vertical direction. The volume of the ice storage portion 13 is set to be slightly larger than that of the ice so that one piece of rectangular parallelepiped ice of about 500 g can be stored. The weight of ice is set to an arbitrary weight within the range of 1% or more and 10% or less of the weight of water to be put into the seafood container 10, and the ice can be sized to contain ice within the range. The size of the accommodating portion 13 is set. By putting a single piece of rectangular parallelepiped ice in the ice storage section 13, it is possible to maintain a longer time until the ice is completely thawed than in the case where a large number of small pieces of ice (total weight is 500 g) are placed. While the temperature of the water in the seafood container 10 can be gradually lowered, the time for maintaining the optimum temperature can be lengthened.

  Each air pump accommodating portion 11 has a rectangular opening in plan view, and the opening gradually decreases downward. By configuring in this way, the air pump can bite into the side wall of the air pump accommodating portion 11 and be fixed as the air pump 14 is positioned downward. Each of the two air pump accommodating portions 11, 11 can accommodate the air pump 14, and the two air pumps 14, 14 can be used, or one air pump 14 can be used among the two air pump accommodating portions 11, 11. It can also be accommodated and used in either one of these. FIG. 2 shows a case where the air pump 14 is accommodated in the right air pump accommodating portion 11 when viewed from the front. Further, a rectangular opening (a square shape in FIG. 3A) is formed in front of the lower portion of the front side wall 8 of the air pump accommodating portions 11 and 11, and the water that has entered the air pump accommodating portions 11 and 11 is immediately stored in the container. It can be discharged to the outside.

  As the air pump 14, a casing in which a dry battery (or a secondary battery) and a pump driven by the dry battery are accommodated in a casing is used. In addition, one end of an air tube is connected to the air pump, and an air disperser is connected to the other end of the air tube, and air from the air disperser is supplied to water in the seafood container 10. . The air distributor is locked (fitted) and fixed to one of the two recesses 15 and 16 formed in the bottom wall 4. A pair of locking projections 17 and 17 for locking and holding the air tube is formed in the vicinity of each recess 15 or 16. Further, a groove M for fitting and fixing the air tube is formed in the bottom wall 4 and the main body side wall 5. The air disperser (not shown) of the air pump 14 accommodated in the right air pump accommodating part 11 is engaged with the recess 15 located in the vicinity of the opening 12K, so that it moves from the opening 12K into the seafood accommodating part 10. The molten water can be efficiently moved to the side away from the opening 12K by the air from the air disperser.

  The inner surfaces 18, 19, 20, and 21 of the corners of the four walls 6, 7, 9, and 12 constituting the seafood container 10 are R-processed, and the inner surfaces 18, 19, 20, and 21 of the four corners are processed. The curvature radii of the inner surfaces 18 and 19 of the two corners located on the vertical wall 12 side are larger than the curvature radii of the inner surfaces 20 and 21 of the remaining two corners. Specifically, the radius of curvature R1 of the inner surfaces 18, 19 of the two corners located on the vertical wall 12 side is 50 mm, and the radius of curvature R2 of the inner surfaces 20, 21 of the remaining two corners is 25 mm, which is half of 50 mm. Yes. By setting in this way, not only can the strength of the corners on the vertical wall 12 side be increased, but also the water on the vertical wall 12 side in the seafood container 10 can be moved smoothly, It can be further suppressed that the water stays and the water in the seafood container 10 stagnates.

  As shown in FIGS. 1 and 2, annular fitting ridges 2T projecting upward are formed on the upper end surfaces of the left and right side walls 6 and 7 and the front and rear side walls 8 and 9, that is, the upper end surface of the main body side wall 5. Is provided. An annular recess (not shown) that fits into the fitting ridge 2T is formed at the bottom of the lid 3.

  As shown in FIGS. 2 and 5 (a) and 5 (b), a partition plate 22 for partitioning the space in the seafood container 10 is engaged with the vertical wall 12 and the rear side wall 9 facing each other. Vertical grooves 23, 24, 25, and 26 are formed as two sets of locking portions for fixing. Therefore, as shown in FIG. 5 (a), by inserting the front and rear end portions of the two partition plates 22 and 22 into the pair of front and rear longitudinal grooves 23, 24, 25, and 26 from above, the partition plates 22 and 22 are inserted. They can be set substantially parallel with a predetermined interval in the left-right direction. As a result, the seafood container 10 can be partitioned into three housing spaces 27, 28, and 29, and the seafood can be divided into three housing spaces 27, 28, and 29 and stored. For example, when the fish is housed in each housing space 27, 28, or 29 with the mouth of the fish facing the vertical wall 12, the air pump 14 is housed in the right air pump housing portion 11, and the air pump 14 air By locking the disperser (not shown) in the recess 15 located in the vicinity of the opening 12K, the air spouted from the air disperser (not shown) can easily reach the fish mouth. Become advantageous. Each longitudinal groove 23 or 24 or 25 or 26 has a tapered surface whose width becomes narrower from the upper end toward the lower end. By providing such a configuration, it is easy to insert the partition plates 22 and 22 from the upper ends of the vertical grooves 23 or 24 or 25 or 26, but the lower end portion of the partition plate 22 is surely secured at the narrowed portion of the lower end portion. It is possible to suppress the set partition plate 22 from being lifted by receiving the buoyancy of water.

  Further, as shown in FIG. 5B, the partition plate 22 has a right vertical groove 25 on the front side (or may be a left vertical groove 23 on the front side) and a rear side so that one partition plate 22 is inclined. And can be inserted into the left vertical groove 24 (or the right vertical groove 26 on the rear side) from above. Accordingly, the seafood container 10 can be partitioned into two storage spaces 30 and 31, and the seafood can be divided into two storage spaces 30 and 31 and stored. Here, the case has been shown in which the seafood container 10 can be partitioned into a maximum of three storage spaces 27, 28, and 29, but the seafood container 10 can be partitioned into four or more storage spaces. You may comprise, and the structure which abbreviate | omits the vertical groove | channels 23, 24, 25, and 26 and cannot partition the seafood accommodating part 10 may be sufficient.

  Further, as shown in FIG. 4C, a gap S1 is formed between the lower ends 22A and 22A of the partition plates 22 and 22 and the upper surface (mounting surface) 4A of the bottom wall 4, and the gap The water in the seafood container 10 can move between the three storage spaces 27, 28, 29 through S1. For example, it is preferable to set the gap S1 to an arbitrary value between 20 mm and 40 mm. In addition, the upper end 22B of the partition plate 22 is made lower than the water surface W to form a gap S2 from the upper end 22B of the partition plate 22 to the water surface W. Between the three accommodation spaces 27, 28, 29 through the gap S2, The water in the seafood container 10 can be moved. Also in this case, it is preferable to set the gap S2 to an arbitrary value between 20 mm and 40 mm. By forming the gaps S1 and S2 in this way, the movement of water becomes smooth and it is easy to eliminate the stagnation of water.

  In addition, the cold storage container which concerns on this invention is not limited to embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

  In the embodiment, the rectangular seafood transport container is shown in a plan view, but it may be a square seafood transport container in a plan view, or a circular or polygonal seafood transport container. There may be.

  Moreover, although the case where the two air pump accommodating parts were provided was shown in the said embodiment, you may implement by providing one or three or more air pump accommodating parts.

  In the embodiment, the opening 12K formed in the vertical wall 12 is formed in a slit shape. However, a large number of circular or square small holes may be formed at intervals to form the opening 12K.

  Moreover, in the said embodiment, although ice was used as a refrigerant | coolant for lowering | hanging the water temperature in a seafood accommodation part, you may use the cool storage agent which filled the plastic agent or the bag with the gel agent. The cool storage agent is stored in a refrigerant storage unit that can store the cool storage agent, and the size of the cool storage agent is set to a size that has a capacity that allows the water temperature in the seafood storage unit to be lowered to a predetermined temperature.
