Description

  The present invention relates to a foamed resin container for storing and transporting fish and shellfish such as live fish alive with air blown from an air pump in a container filled with water.

  In order to transport live fish and the like in a foamed resin container, a technique of transporting air while supplying air to the live fish contained in the water filled in the foamed resin container with an air pump has been widely used. For example, Patent Document 1 discloses a method for putting fish and shellfish into a hibernating state. However, in this document, an air pump is accommodated to prevent water from entering, and the outside of a foam container that accommodates live fish is disclosed. In addition, a pocket-shaped storage portion is separately formed of the same foamed resin material, and a structure is formed in which a hole is formed in the lower portion of the storage portion for drainage. This is because it is essential to prevent the air pump from shutting down due to water immersion. If the air pump stops, it will immediately lead to the death of live fish.

  Furthermore, as described above, even if the air pump storage part is provided outside the foam container, the bubbles of the air sent out from the air pump will flow backward to reach the air pump storage part and prevent the air pump from being damaged. For this purpose, a complicated measure as disclosed in Patent Document 2 is required.

  Patent Documents 3 and 4 disclose an invention in which water is drained from a container side wall to the outside in order to prevent water from entering the pump housing chamber via an air tube.

On the other hand, Patent Document 5 discloses a technique for draining ice water generated in a foamed container through a hole penetrating the container side wall vertically.

  As described above, in the case of a conventional container for transporting live fish, the lid is closed when the live fish container is transported, and water is leaked from the fitting portion between the container and the cover, or physical force is applied to open the cover. Usually, a tape is wound around the fitting portion between the container and the lid so as to prevent the trouble of causing the trouble. However, in order to prevent water and bubbles generated by the air pump from entering the air pump housing part and the air pump from operating, the water to enter the air pump housing part is drained exclusively on the side wall surface. Came as a solution. Therefore, although the tape is wound around the fitting portion between the container and the lid, it has been considered that the side wall cannot be wet with these waters.

  However, since live fish containers and other cargoes are often mixed in a transportation means such as a truck, the wetness of the side walls may be disliked. Accordingly, there has been a demand for means for preventing the side walls from getting wet as much as possible when transporting live fish containers.

  In the present invention, in order to prevent water from entering the air pump housing part through the air tube that blows air in a transport container such as live fish that is premised on handling a large amount of water as described above, It is for solving the difficult problem of trying to prevent water wetting on the outer surface of the side wall as much as possible by draining, and has the following configuration.

  That is, the present invention is a foamed resin container that is composed of a container body that partitions a seafood storage part and an air pump storage part, and a lid, and contains water and seafood for storage and transportation, The present invention relates to a foamed resin container in which a recess is provided on the upper end surface and / or the upper end surface of a side wall, and a vertical through drainage hole is provided in the recess.

As a preferred embodiment,
(1) A vertically penetrating drainage hole is provided at the intersection of the recess on the upper end surface of the partition wall and the recess on the upper end surface of the side wall.
(2) Attaching a waterproof seal to the air pump storage part, or a lid to the air pump storage part separately from the closure to the seafood storage part,
(3) A protruding wall formed higher than the upper end surface of the side wall of the seafood storage unit is provided on the upper end surface of the partition wall and the upper end surface of the side wall surrounding the air pump storage unit.
(4) When the foamed resin containers are stacked, the water flowing down from the vertical through drain holes of the stacked upper container body is the lid drain hole of the lower cover body, and further the vertical through drain holes of the lower container body. Characterized by flowing down through,
The present invention relates to the foamed resin container described above.

  The present invention has made it possible to satisfactorily prevent intrusion of water into the air pump storage section in a transport container such as live fish with a very simple configuration. Furthermore, since the intruding water is drained vertically in the side wall, water wetting on the outer surface of the side wall can be effectively reduced. That is, the water collected in the recess provided on the upper end surface of the side wall of the container body and / or the recess provided on the upper end surface of the partition wall is drained from the vertical through drain hole provided in the recess and the lid body drain provided with the lid body. Since it is collected in the lowermost foamed resin container through the holes, water wetting on the outer surface of the side wall of each foamed resin container can be efficiently reduced. In addition, if a receiver for collecting water is prepared at the bottom of the bottom wall of the bottom foam resin container, other mixed cargo can be well prevented from contamination due to water leakage from transport containers such as live fish. it can. In addition, by applying a waterproof seal to the air pump storage part and closing the air pump storage part separately from the seafood storage part, the water pump is prevented from entering the water pump. Since the leakage of water can also be greatly reduced, the prevention of contamination due to water leakage becomes more reliable.

  Furthermore, in the present invention, by providing a protruding wall in which a part of the upper end surface of the partition wall and the side wall upper end surface of the side wall forming the air pump housing portion is made higher than the upper end surface of the other side wall, water can be more reliably prevented from entering. preferable.

  The foaming resin constituting the foamed resin container comprising the container main body and the lid of the present invention includes a foaming agent such as polystyrene resin such as polystyrene, polyolefin resin such as polyethylene and polypropylene, and synthetic resin such as polyurethane resin such as polyurethane. Is impregnated and press-fitted to give foaming properties and foamed. Among them, expanded polystyrene is preferably used from the viewpoint of characteristics and cost.

  In addition, the air pump of the present invention refers to an air pump that is driven by a battery or the like and is generally commercially available for blowing air into a water tank or the like. What is necessary is just to select from commercially available goods suitably according to the blowing capacity | capacitance of air or blowing time. In order to transport the fish and shellfish alive using such an air pump, water containing salt contained in the container body, seawater or fresh water (in the present invention, any expression is simply expressed as water. Etc.) and blow air into the water.

  Air pumps are not waterproof in most cases due to price and performance, so if the air pump is directly splashed with water, or if it is submerged, the pump will stop and air will stop blowing, resulting in the death of live fish. Fall into. The present invention proposes a drainage structure that is not submerged as much as possible in the air pump housing portion provided at an appropriate position.However, if necessary, a waterproof sheet is attached to the air pump housing portion or the air pump housing portion is attached. It is preferable to use a lid that can be closed separately from the lid for the seafood container. The lid that closes the air pump storage part may be a lid that closes only the air pump storage part, or a lid that satisfactorily closes both the air pump storage part and the seafood storage part.

  In the container body of the present invention, the seafood storage part and the air pump storage part may be adjacent to each other via a partition wall, and the container body shape as a whole may be a rectangular shape or a circular shape. The type storage unit and the air pump storage unit may be rectangular or circular. In the latter case, the shape of the container body itself may be a distorted shape. Of the side walls of the container body, the side wall that actually constitutes the air pump storage part is referred to as the air pump storage part side wall, and the side wall that does not actually constitute the air pump storage part is referred to as the seafood storage part side wall. May be expressed. Therefore, in this invention, it can be said that an air pump accommodating part is comprised by the partition and air pump accommodating part side wall which divide an air pump accommodating part and a seafood accommodating part.

  A concave groove is provided on the upper end surface of the side wall and / or the upper end surface of the partition wall that divides the air pump storage part, so that water injected into the container body is blocked by the concave groove and does not reach the air pump storage part as much as possible. Composed. And the vertical penetration drain hole which opens to a ditch | groove and penetrates the inside of a side wall vertically is provided. The other of the vertical through drain holes is open to the bottom wall of the container body. Thus, by providing the vertical hole through hole in the side wall, the water accumulated in the concave groove can be drained to the bottom of the container main body without wetting the side wall surface. In this case, it is preferable to provide the vertical through drainage hole so as to open at the intersection of the concave groove provided on the upper end surface of the container body side wall and the concave groove provided on the upper end surface of the partition wall. This is because even if the intersecting portion is provided with a vertical through drainage hole, it has a reason such that it is a portion where the decrease in strength is small and drainage efficiency is good.

  Furthermore, in the present invention, by designing the side wall (that is, the side wall of the air pump storage unit) and the partition wall constituting the air pump storage unit to be higher than the other side wall (that is, the seafood storage unit side wall), the air pump storage unit It is possible to efficiently prevent water from entering the water, which is an extremely effective mode.

  The foamed resin container of the present invention is used for transporting fish and shellfish, but the contents accommodated in the container, that is, the transported object, are not limited to fish transported with water. It can be widely applied to seafood that can be transported alive such as shellfish such as shellfish such as shellfish and tuna, seaweed, and other seafood that is required to be transported while maintaining freshness.

  Next, the present invention will be described with reference to the drawings. However, since these are merely embodiments, the present invention is not limited by these descriptions.

  FIG. 1 is a perspective view showing an embodiment of a container body 2 of a foamed resin container 1 of the present invention. The container body 2 is open on one side and is composed of four side walls 3 and a bottom wall 4. The container body 2 is provided with an air pump storage portion X. This air pump storage part X is comprised by the partition 5 which partitions the seafood storage part Y and the air pump storage part X, and the part of the side wall 3 which surrounds this air pump storage part X (namely, air pump storage part side wall 3A). On the other hand, the seafood storage part Y is formed by a portion of the side wall 3 constituting the seafood storage part Y (that is, the seafood storage part side wall 3B) and the partition wall 5. The air pump is housed in the opening 21 of the air pump housing portion X. It is preferable that the air pump housing portion X is provided with a drain hole 23 that can be drained appropriately so that water can be drained when water enters. FIG. 2 is a perspective view showing an embodiment of the lid 10.

  The side wall upper end surface 6, the partition upper end surface 7, and the lid lower end surface 11 of the lid body 10 are contact surfaces with each other. The side wall upper end surface 6 and the partition wall upper end surface 7 are provided with a ridge 8 provided on the lid lower end surface 11 of the lid 10 and a mating recess 9. The protrusions 8 and the recesses 9 provided on the respective contact surfaces are not particularly limited as long as they can be fitted to each other, and conventionally known uneven fitting structures can be employed. And what is necessary is just to select an uneven | corrugated fitting structure according to the fitting intensity | strength requested | required of the container 1 made from foamed resin of this invention. The fitting structure is preferably solid so that water used by pouring water after the lid is closed does not leak out of the container, and more preferably one that does not open due to impact during transportation. However, even if the fitting is loose, there is no particular limitation because it can be reinforced with an adhesive tape or the like.

  It is most preferable that the concave strip 9 has an annular continuous shape between the side wall upper end surface 6 and the partition wall upper end surface 7. However, the recess 9 on the side wall upper end surface 6 of the side wall 3B in the seafood storage portion side wall 3B may be partially interrupted. Further, the groove 9 on the side wall upper end surface 6 of the seafood storage unit side wall 3B may be partially provided with the ridges 8 and partially with the ridges 9. On the other hand, the lid lower end surface 11 is naturally required to have a concavo-convex fitting structure that corresponds to the concave strip 9 or the concave strip 9 and the convex strip 8 of the sidewall upper end surface 6 and that can be fitted. It is preferable that the concave strip 9 on the partition upper end surface 7 has a continuous shape, and smoothes the flow of water flowing into the concave strip 9 from the seafood storage portion Y by swinging water.

  One of the recesses 9 provided on the side wall upper end surface 6 and the partition wall upper end surface 7 is opened to the recess 9 and the other is opened to the bottom wall of the container body, and penetrates through the side wall. As shown in FIG. In this way, the water accumulated in the recess 9 is drained to the bottom of the container body without wetting the side wall surface. In particular, it is preferable to provide a vertical through drainage hole 40 at the intersection of the recess 9 on the side wall upper end surface 6 and the recess 9 on the partition upper end surface 7.

  2 is a perspective view of the lid body 10 used in the container body 2 of FIGS. 1, 4 and 5, and FIG. 3 is a cross-sectional view of the lid body 10 of FIG. A concave surface 14 is provided on the upper surface 12 of the lid 10, leaving the peripheral edge portion 13. It is preferable that the concave surface 14 is deepened toward the peripheral portion 13 so that water flowing down from the vertical through drain holes 40 and the like of the container body 2 is collected in the vicinity of the peripheral portion 13. And if the lid | cover drainage hole 45 is provided in the position substantially corresponding to the vertical penetration drainage hole 40 provided in the container main body 2, the flowing-down water from the vertical penetration drainage hole 40 of the container main body 2 stacked on top will be made. The vertical through drain hole 40 of the container body 2 located below can be efficiently flowed down. That is, when this structure is adopted, when the foamed resin containers of the present invention are stacked and used, the water overflowing from the seafood storage part Y of the upper container body and flowing down from the vertical hole through drainage groove is discharged into the container body 2. Without wetting the side wall 3, the drainage can be caused to flow down through the lid drainage hole of the lower lid and further through the vertical through drainage hole of the lower container body, which is a preferred embodiment. In addition, 15 of FIG. 2 is an air hole, The air with which the container main body 2 was filled can be discharged | emitted. However, the air hole 15 does not penetrate from the beginning, and a part of the air hole 15 is sealed with a foamed resin, which is a raw material. It is preferable that the air holes 15 are actually inserted and penetrated so as to function actually. However, it is of course possible to make the air hole 15 penetrated from the beginning. When there is water or water bubbles accompanying the air discharged from the air hole 15, it is preferable to drain the lid drain hole 45 with the inclined groove 17 connected to the lid drain hole 45. 4 is a plan view of the container body 2 of FIG. 1, and FIG. 5 is a cross-sectional view taken along the line BB of FIG.

  The air hose extending from the air pump housed in the opening 21 of the air pump housing part X passes through the recess 25 provided in the side wall upper end surface 6 of the air pump housing part side wall 3A and from the recess 27 provided in the partition upper end surface 7 to the seafood housing part Y. , And the bottom wall 4 is rubbed, and 30 is a fastening portion for fastening an air hose or an air outlet located at the tip of the air hose.

  After storing the air pump in the opening 21 of the air pump storage part X, if necessary, a waterproof sheet can be applied to the side wall upper end surface 6 of the air pump storage part side wall 3A surrounding the air pump storage part X and the partition wall upper end surface 7 of the partition wall 5. Even before the lid 10 is closed, the water stored in the seafood storage part Y and the water used when storing the seafood are effectively prevented from entering the air pump storage part X. It is preferable because it is possible. Further, after the lid 10 is closed, water leakage from the drain hole 23 provided in the air pump storage portion X does not occur, so that the drainage from the laminated foamed resin container 1 is conducted through the vertical through drain hole 40 and Since only the drainage through the lid drainage hole 45 is performed, contamination of the sidewall 3 by drainage can be extremely effectively prevented. That is, as long as the drainage from the bottom wall 4 of the vertical through drain hole 40 of the lowermost foam resin container 1 is performed, the laminated foam resin container 1 is sufficiently prevented from being contaminated and contaminated with other cargo due to mixed loading. Is very preferable.

  Instead of sticking a waterproof sheet to the side wall upper end surface 6 of the air pump storage unit side wall 3A surrounding the air pump storage unit X and the partition wall upper end surface 7 of the partition wall 5, only the opening 21 of the air pump storage unit X can be sealed. The same effect as that obtained by pasting the above waterproof sheet can be obtained by covering a foamed resin plate-like lid. The waterproof sheet with the air pump storage unit X and the lid that has been closed are stuck or closed as they are, and after the seafood is stored, the seam storage unit Y and the air pump are stored by the lid 10. It is preferable to close the part X together and use it for transportation, storage and the like.

Set high. The portions of the side wall upper end surface 6 and the partition upper end surface 7 that are set high are referred to as protruding walls 50.

  According to such an embodiment, after the air pump is stored in the opening 21 of the air pump storage part X, the water overflowing from the seafood storage part Y is blocked by the projection wall 50, so that it is difficult to be immersed in the air pump storage part X. It is preferable because damage can be reduced. In particular, if the container body 2 is closed by the lid 10 shown in FIG. 10 (showing a longitudinal sectional view) adapted to the container body 2 shown in FIGS. Since water immersion in can be prevented even better, it is a more preferred embodiment. Since the lid body 10 in FIG. 10 is devised so that it can be fitted completely horizontally even if the protruding wall 50 exists or is closed by fitting with the container body 2, the lid body 10 is made of foamed resin. Even when the containers 1 are stacked in the vertical direction, no gap is generated between the containers and no rattling or the like occurs. Therefore, the container 1 can be handled in the same manner as the normal foamed resin container 1.
