Description

  The present invention is a cold insulation container made of foamed synthetic resin, a box-shaped container body having an upper surface opened, and an upper lid detachably attached to the container body so as to open and close the upper surface opening of the container body. It is related with the cold storage container provided with.

  Conventionally, fish (for example, salted salmon) is stored in a wooden box and transported to a destination. The wooden box has a rectangular frame body and a plan view of the side plate section in a state of being arranged in parallel with a distance from each other over a rectangular frame body and the lower ends of two opposing side plate sections of the frame body. It consists of a main body part made up of a number of long and thin strip-shaped plate members connected by nailing and a lid placed on the upper end of the main body part. The lid is composed of a large number of long and thin strip-shaped plate materials arranged in parallel at intervals, and a plurality of plate materials arranged in a direction orthogonal to the strip-shaped plate material to connect the numerous strip-shaped plate materials. Has been.

  When storing and shipping fish in such a wooden box, first of all, fill the gaps between the strip-shaped plate members constituting the bottom of the main body, and prevent the fish from directly hitting the strip-shaped plate materials. Place the sheet on the bottom of the body. Subsequently, a vinyl sheet is laid on the foam sheet so that the drip generated from the fish does not leak outside. The fish is stored in this state, and then a paper absorbent material called a paper perch for sucking the drip generated from the fish is covered over the fish. Then, the top of the absorbent material is covered with a foam sheet as a cushioning material with a wooden lid. After covering in this state, the product is shipped with the band wrapped around.

  In the case of the above wooden box, in order to store the fish in a hermetically sealed state or to prevent the fish from being damaged by a hard strip-shaped plate material, the foam sheet is laid on the top and bottom of the fish and the fish is covered (wrapped) with a vinyl sheet. ) Is required. Therefore, there has been a disadvantage that the packing operation of the fish becomes a troublesome operation which is troublesome.

  A cold insulated container made of foamed synthetic resin has been proposed so that the packing operation can be easily performed. The cold storage container has a container main body composed of a rectangular bottom wall and four side walls standing upward from the outer peripheral edge of the bottom wall, and a container main body so as to open and close the upper surface opening of the container main body. On the other hand, it is comprised from the cover body attached detachably. The lid body is composed of a flat plate portion having substantially the same size as the bottom wall, and a skirt portion having a fitting portion that can hang downward from the outer peripheral edge of the flat plate portion and can be fitted to the fitted portion of the container body. (For example, refer to Patent Document 1).

  In the cool container of patent document 1, since the operation | work which spreads the foam sheet and vinyl sheet arrange | positioned under a fish, and the operation | work which covers a foam sheet on a fish can be made unnecessary, there exists an advantage which can perform a packing operation | work easily. . However, since the external shape of the cold storage container does not have an excellent design like that of a wooden box, it is impossible to completely switch from the wooden box to the cold storage container made of foamed synthetic resin.

  Then, this invention is made | formed in view of this situation, and makes it a subject to provide the cold storage container which can perform packing operation | work easily, maintaining the external shape like a wooden box.

  The cold storage container according to the present invention is a cold storage container made of foamed synthetic resin, and is detachably attached to the container main body so as to open and close the box-shaped container main body whose upper surface opens and the upper surface opening of the container main body. In the cold storage container having an upper lid to be attached, the upper lid includes a plurality of long and thin strip-like portions arranged in parallel at intervals, and a connecting portion for connecting and integrating these strip-like portions. It is configured.

  According to the present invention, since it is a cold insulated container made of foamed synthetic resin, it is possible to store (accommodate) fish without damaging them without placing a foam sheet in the container body. After the fish is stored in the container main body, the upper lid becomes a cushioning material by attaching the upper lid to the container main body. Therefore, a foam sheet that covers the fish like a wooden box is not required. In addition, the absorber which absorbs the drip which generate | occur | produces from a fish will be put in a container main body as needed. Here, the upper cover of the cold storage container is constituted by a large number of long and thin strip-like portions arranged in parallel at intervals, and a connecting portion for connecting and integrating these strip-like portions. Therefore, the external shape is very similar to the lid of a wooden box, and excellent design can be ensured.

  In the cold storage container according to the present invention, the outer edge of the connecting portion is located on the inner side of the outer edges of the plurality of strip-shaped portions, and the connecting portion is attached in the state where the upper lid is attached to the container body. May enter the upper surface opening of the container body, and the outer edge portion of the strip-shaped portion located outside the outer edge of the connecting portion may be in contact with the upper surface of the peripheral edge of the container body.

  According to such a configuration, with the upper lid attached to the container body, the connecting portion enters the upper surface opening, the outer edge portion of the strip-shaped portion abuts the upper surface of the peripheral edge of the container body, and the upper lid is attached to the container body. (Fitting) is easily completed.

  Moreover, in the cold insulation container which concerns on this invention, it is preferable that the texture processing for forming the pattern of a grain is given to the surface of the said strip-shaped part.

  According to such a configuration, if a grain pattern is formed on the surface of the strip-shaped portion, the texture of wood can be given, and the upper lid can be configured with better design.

  Moreover, in the cold insulated container which concerns on this invention, it is preferable to set the foaming ratio of the said container main body and the said upper cover to 30 times-50 times.

  According to such a configuration, if the container main body and the upper lid are set to a low foaming ratio of 30 to 50 times, it is possible to reduce the thickness while ensuring the strength of the cold storage container. It can be configured as an upper lid with a wood texture and excellent design.

  As described above, according to the present invention, it is possible to maintain an external shape like a wooden box by providing an upper lid provided with a large number of long and thin strip-shaped portions, although it is a cold insulated container made of foamed synthetic resin. It is possible to provide a cold storage container that can be easily packed while ensuring design.

It is a perspective view which shows the state which piled up three of the container main bodies of the cold storage container, put the upper cover on the uppermost container main body, and hung the band around.

  Hereinafter, an embodiment of a cold container according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1 and FIG. 2, the cold insulation container 1 is a box-shaped foam synthesis that can accommodate, for example, several (for example, six) salt jars (not shown) from the upper surface opening 10 </ b> A. A container body 10 made of resin and an upper lid 20 made of foamed synthetic resin for closing the upper surface opening 10A of the container body 10 are configured. The foamed synthetic resin is not particularly limited, and various foamed synthetic resins such as foamed polystyrene, foamed polyethylene, and foamed polypropylene can be used. The firing magnification is set to 40 times, but any value between 30 times and 50 times can not only be thinned while ensuring strength, but also can have a texture of wood grain. preferable. 1 and 2 are containers intended for medium-sized fish such as salmon, salmon, and yellowtail, but can store small fish such as salmon and salmon in addition to large fish such as yellowtail and tuna. It may be a container of a size.

  As shown in FIGS. 1, 2, 4 and 5A and 5B, the container main body 10 is formed in a substantially rectangular shape in plan view, and is placed on which salt salmon (hereinafter referred to as fish) is placed. A bottom 11 provided with a mounting surface 11A, a pair of left and right side walls 12 and 12 erected upward on both edges in the left-right width direction, which are a pair of long sides of the bottom 11, and a pair of short sides of the bottom 11 And a pair of front and rear side walls 13 and 13 erected upward from the front and rear edge. At the upper ends of these four side walls 12, 12, 13, 13, the upper surface opening 10A for taking in and out fish is formed.

  The pair of left and right side walls 12 and 12 includes a lower portion 12A having a portion corresponding to the bottom portion 11 that is an outer surface recessed (recessed) inside the upper portion 12B above the upper portion 12B. A step is formed at the boundary with the lower portion 12A. Further, the pair of front and rear side walls 13 and 13 includes a lower portion 13A whose outer surface is deeper (retracted) than the upper portion 13B on the upper portion 13B. A step is formed at the boundary with the portion 13A. 13 A of lower parts are comprised from the uneven part which formed the convex part 13a and the recessed part 13b alternately in the left-right direction. In addition, by making the top and bottom heights of the lower portions 12B and 13B coincide with each other, the lower portions 12B and 13B can form a peripheral wall portion continuous in the circumferential direction, and are associated with a wooden box made of wood. The texture of the wood can be given even more. Therefore, it can be set as the container main body 10 excellent in design property.

  Further, as shown in FIG. 4, the pair of left and right side walls (long side walls) 12 and 12 have inner surfaces such that the thickness D1 at the center in the front-rear direction is thicker than the thicknesses D2 and D2 at both ends in the front-rear direction. It is formed so that it swells inward in the front-rear direction central part side, and even when many cold storage containers 1 are stacked (for example, three or more), the side walls 12 and 12 of the lower cold storage container 1 are stacked in large numbers. It is possible to avoid being crushed or deformed by the weight applied from the cold storage container 1.

  A plurality (10 in the figure) of rectangular protrusions 11B projecting downward are formed at predetermined intervals on the outer peripheral edge of the bottom surface (bottom surface) of the bottom portion 11. Each of the protrusions 11B is formed with two protrusions 11B and 11B in the vicinity of the four corners of the bottom portion 11, and one protrusion 11B is formed at approximately the center in the longitudinal direction of the two long side portions of the bottom portion 11. The shape and size of the protrusion 11B can be freely changed.

  Further, as shown in FIGS. 5A and 5B, the bottom portion 11 is formed with tapered surfaces 11T1 and 11T2 that become higher from the both ends in the left-right direction toward the center in the left-right direction, and from the both ends in the front-rear direction. Tapered surfaces 11T3 and 11T4 that are higher toward the center are formed. Therefore, the drip generated from the fish and the water that has melted the ice are moved and guided to the four corners of the mounting surface 11A by the guiding action of the tapered surfaces 11T1, 11T2, 11T3, and 11T4 of the bottom portion 11. After that, it is guided to move to a discharge port 15 to be described later and discharged to the outside.

  At the four corners of the side walls 12, 12, 13, and 13 of the container body 10, as shown in FIGS. 2, 4, and 5C, walls having a thickness larger than those of the side walls 12, 12, 13, and 13 are provided. A portion 16 is formed, and a water passage hole 14 penetrating in the vertical direction is formed in the wall portion 16. The water passage hole 14 has a tapered opening portion 14A whose diameter decreases toward the lower side, an upper tapered portion 14B whose diameter decreases from the lower end of the opening portion 14A toward the substantially central portion in the vertical direction, and a substantially central portion in the vertical direction. A lower tapered portion 14C having a diameter that increases toward the lower side from the portion. The wall portion 16 is formed by obliquely connecting adjacent side walls 12 and 13 in order to ensure a predetermined strength because the water passage hole 14 is formed. By forming in this way, the corner part of the container main body 10 can project the inside, and the wall part 16 which has thickness can be comprised. The protruding end surface 16A of the wall portion 16 is a flat surface.

  In addition, an inclined surface 11K for guiding drip and water to the water passage hole 14 side is formed at each of the four corners of the mounting surface 11A of the bottom portion 11, and the drip guided by the inclined surface 11K A discharge port 15 for discharging water to the outside through a discharge space 14 </ b> D communicating with the water hole 14 is formed at the lower end of the wall portion 16 formed at each of the four corners of the container body 10.

  As shown in FIG. 2, the discharge port 15 is formed in a horizontally long rectangular shape, and the size of the left and right width thereof is smaller than the size of the left and right width of the wall portion 16. The accompanying strength reduction of the container body 10 can be suppressed.

  Further, as shown in FIGS. 2 and 5 (a) and 5 (c), connecting portions between the both ends of the wall portion 16 in the left-right width direction and the side walls 12 or 13 adjacent thereto in the left-right direction (thick in FIG. 2). 17 (shown by a line) and a connecting portion 18 (shown by a thick line in FIG. 2) 18 between the inner lower end of the four side walls 12, 12, 13, 13 and the inside of the outer periphery of the bottom part 11 have a radius of curvature. It is formed on an arc surface drawn by R3 (an arc surface that protrudes outwardly, see FIG. 5C) to increase the strength of the container body 10.

  As shown in FIGS. 3A, 3B, and 3C, the upper lid 20 has a substantially rectangular shape with a slightly smaller dimension than the upper surface opening 10A so as to smoothly enter the upper surface opening 10A of the container body 10. The flat portion 21 (corresponding to the connecting portion) and a large number (five in the figure) of elongated strip-shaped portions 22 projecting upward from the flat portion 21. All the strip-shaped portions 22 have the same shape and the same size (the same thickness in the vertical direction), and the outer edge of the flat portion 21 is located inside the outer edges of the five strip-shaped portions 22. That is, both ends in the long side direction (front-rear direction) of the flat portion 21 are located inside the both ends in the longitudinal direction of the five strip-shaped portions 22, and both ends in the short side direction (left-right direction) of the flat portion 21 are both ends in the left-right direction. The strip-shaped portions 22 and 22 are located on the inner side of the outer ends in the left-right direction. The larger the gap between the flat portion 21 and the upper surface opening 10A, the easier the flat portion 21 can enter the upper surface opening 10, but the sealing degree decreases. While setting. In order to realize a sealed state, the dimension of the flat portion 21 may be set to a state without the gap (a state in which the flat portion 21 and the upper surface opening 10A are fitted).

  The flat portion 21 has a shape including straight cut portions 21K cut obliquely at four corners of a rectangular plate-like body. Moreover, the flat part 21 comprises the connection part for connecting all the strip-shaped parts 22 in those lower sides, and integrating this strip-shaped part 22. FIG.

  Each of the five strip-shaped portions 22 is arranged so that the longitudinal direction thereof is along the long side direction of the flat portion 21, and the strip-shaped portions 22, 22 adjacent to each other are arranged at equal intervals. Is arranged.

  Further, as shown in FIG. 3A, each of the three strip-shaped portions 22 positioned between the two strip-shaped portions 22, 22 arranged at both ends is upward from the upper surface 21A of the flat portion 21. The first upper portion 22A protrudes from the both ends of the first upper portion 22A in the longitudinal direction and extends outward in the front-rear direction and protrudes from the flat portion 21. Each first end portion 22B also extends outward in the front-rear direction from the upper portion of the side surface 21B on the short side of the flat portion 21. Therefore, as shown in the enlarged view of FIG. 3C, the vertical thickness F1 of the first end portion 22B is almost twice the vertical thickness F2 of the first upper portion 22A. Yes. Thus, by increasing only the thickness of the first end portions 22B and 22B, the thickness F3 of the upper lid 20 can be reduced as much as possible without deteriorating the appearance when the upper lid 20 is closed. . Here, the thickness F1 in the vertical direction of the first end portions 22B and 22B is almost twice the thickness F2 of the first upper portion 22A, but may be set to any value.

  Furthermore, the strip-shaped portion 22 on the lower side (left side) of FIG. 3 among the strip-shaped portions 22 and 22 arranged at both ends includes a second upper portion 22C that protrudes upward from the upper surface 21A of the flat portion 21; It consists of an extended portion 22D that protrudes outward from the extension of the flat portion 21 from the second upper portion 22C. The extended portion 22D includes a second extended portion 22a extending from the left and right ends of the second upper portion 22C to the outer side in the left and right directions, both longitudinal ends of the second extended portion 22a and both longitudinal ends of the second upper portion 22C. The second end portions 22b and 22b extend in the direction. The second extension portion 22a and the second end portions 22b and 22b also extend from the upper portion of the flat portion 21 in the same manner as the first end portion 22B. Therefore, the thickness in the vertical direction of the second extension portion 22a and the second end portions 22b and 22b is approximately twice the thickness of the second upper portion 22C. In this way, by increasing only the thickness of the second extension portion 22a and the second end portions 22b, 22b, the appearance of the outer lid 20 when it is closed is not deteriorated, and the thickness of the upper lid 20 is as thin as possible. Can be Here, the thickness of the second extension portion 22a and the second end portions 22b and 22b in the vertical direction is almost twice the thickness of the second upper portion 22C. May be.

  As shown in FIGS. 1, 2, and 3 (a), 3 (b), the front-rear direction of the lateral sides of the two strip-shaped portions 22, 22 located at the left and right ends of the strip-shaped portion 22. In each of the two upper end corners on the front side and the rear side, a recess 22H is formed in which the band B hung around the cold insulation container 1 enters and is positioned.

  Each of a pair of opposing side surfaces 22F and 22G rising from the flat portion 21 of the five strip-shaped portions 22 (especially, see an enlarged view of FIG. 3C) is a tapered surface located on the inner side in the left-right direction toward the upper end side. Is formed. If the taper surface is formed in this way, there is an advantage that the molded product is easily released when the mold is separated after the molding. In addition, in the enlarged view of FIG.3 (c), in order to make a taper surface easy to understand, it was drawn as a figure which enlarged the angle, but it is a taper surface of a small angle in fact.

  Looking at the upper lid 20 having the above-described configuration, a groove portion 19 that is one step lower is formed between the strip-like portions 22 and 22 that are adjacent in the left-right direction. The band B that is hung around can be easily grasped by pushing a finger into the groove portion 19. The groove portion 19 is formed by an upper surface 21A of the flat portion 21 and a pair of left and right side surfaces 22F and 22G rising from the flat portion 21 of the strip-shaped portions 22 and 22.

  As the upper lid 20 having the above-described configuration is attached to the container body 10, the flat portion (connecting portion) 21 enters the upper surface opening 10 </ b> A of the container body 10 and extends to the outside from the flat portion (connecting portion) 21. The left and right outer end portions of the strip-shaped portion 22 positioned at both ends and both the left and right ends of the abutment 22 abut on the upper surface 10B (see FIGS. 2 and 4) of the peripheral edge of the container body 10, thereby Installation is complete. At this time, since the flat portion (connecting portion) 21 enters the upper surface opening 10A of the container body 10, the upper lid 20 is positioned so as not to move in the front-rear direction and the left-right direction with respect to the container body 10. It is in a state. In the state where the upper lid 20 is attached to the container body 10, both longitudinal end faces of the strip-shaped portion 22 of the upper lid 20 are flush with the outer surfaces of the front and rear side walls 13, 13. Further, the left and right outer end surfaces of the strip-shaped portions 22 and 22 of the upper lid 20 positioned at both ends in the left and right direction are flush with the outer surfaces of the left and right side walls 12 and 12.

  A procedure for storing the fish in the cold storage container 1 having the above-described configuration immediately before shipment will be described. First, a predetermined number (several) of fish is stored in the first container body 10. Subsequently, a predetermined number (several) of fish is stored in another second second container body 10 without the upper lid 20, and the second container body 10 is placed on the upper end of the first container body 10. Stack up. At this time, the plurality of (10 in the figure) rectangular protrusions 11B provided on the outer peripheral edge of the bottom surface of the bottom 11 of the second container body 10 abut on the inner surface of the upper end of the first container body 10 to thereby The second container body 10 can be stacked in a state where the second container body 10 is positioned in both the front-rear direction and the left-right direction with respect to one container body 10. Further, when it is desired that the bottom surface of the second container main body 10 is not touched by the fish, a foam sheet is laid on the fish stored in the first container main body 10. Subsequently, without placing the upper lid 20 on the second container body 10, a predetermined number (several) of fish is stored in another third container body 10, and is placed on the upper end of the second container body 10. The third container body 10 is stacked and the upper lid 20 is covered. At this time, similarly to the above, a plurality (ten in the figure) of rectangular protrusions 11B provided on the outer peripheral edge of the lower surface of the bottom portion 11 of the third container body 10 are applied to the inner surface of the upper end of the second container body 10. By making contact, the third container body 10 can be stacked with the second container body 10 positioned in both the front-rear direction and the left-right direction. In addition, when it is desired that the bottom surface of the third container body 10 does not touch the fish, a foam sheet is laid on the fish stored in the second container body 10.

  In a state where the three container main bodies 10 are stacked and the upper lid 20 is attached to the uppermost third container main body 10, the two container B are wound to integrate the three container main bodies 10 (see FIG. 6). . At this time, since a gap corresponding to the height of the protrusion 11B is formed between the bottom surface and the floor surface of the first container body 10, there is an advantage that the band B can be easily applied. Moreover, even when storing in a freezer or a refrigerator, even when water freezes between the protrusion 11B on the bottom surface of the first container body 10 and the floor surface, the container body 10 can be easily peeled off from the floor surface. In addition, since a groove portion 19 that is one step lower is formed between the strip-shaped portions 22 and 22 that are adjacent in the left-right direction in a state where the band B is hung, the band B is formed by pushing a finger into the groove portion 19. The three container bodies 10 can be easily carried by grasping the bands B and B. In addition, after the drip and water in the container main body 10 located in the uppermost stacked portion are guided to the water flow holes 14 of the first-stage container main body 10 through the water-flow holes 14 of the second-stage container main body 10. , Discharged outside.

  As described above, the cold insulation container 1 is composed of the foamed synthetic resin container main body 10 and the upper lid 20 so that the fish can be stored (accommodated) without being damaged even if the foam sheet is not laid in the container main body 10. be able to. When the upper lid 20 is attached to the container main body 10 after the fish is stored in the container main body 10, the upper lid 20 becomes a cushioning material, so that a foam sheet that covers the fish like a wooden box can be eliminated. And the upper cover 20 of the cold insulation container 1 is flat for many long thin strip-shaped parts 22 arranged in parallel at intervals, and connecting these strip-shaped parts 22 and integrating the strip-shaped parts 22 Since it is comprised from the part (connection part) 21, it becomes the external appearance very similar to the cover of the wooden box, and can ensure the outstanding design property. Further, by providing the container body 10 with the lower portion 12A and the concavo-convex portion 13A, the container body 10 can be made to have an appearance shape very similar to a wooden box, and further excellent design can be ensured. Can do.

  As shown in FIG. 6, the surface of all five strip-shaped portions 22 is subjected to graining to form a grain pattern. In FIG. 6, all the grain patterns formed on the five strip-shaped portions 22 are the same pattern, but may be formed in different grain patterns. Further, a portion other than the surface of the strip-shaped portion 22, for example, the four peripheral side surfaces of the strip-shaped portion 22 may be subjected to a graining process for forming a grain pattern, or the flat portion (connecting portion) 21. The upper surface 21 </ b> A may also be textured. In addition, a graining process for forming a grain pattern may be performed on part or all of the left and right side walls 12 and 12 and the front and rear side walls 13 and 13.

  By coloring the cold storage container into a color of wood, an atmosphere more similar to wood can be produced. As the color to be colored, brown, dark brown, light brown, ocher, etc. are appropriately selected and used. In order to color the cold storage container in the color of wood, for example, it is conceivable to form the cold storage container using foamed synthetic resin particles colored by impregnation with a dye. In this case, the foamed synthetic resin particles of the same color will be used, but the entire cold insulation container should be uniformly colored due to uneven coloring or differences in the degree of foaming for each foamed synthetic resin particle during foaming. Although it is difficult and the color tone is often different partially, there is an effect that the texture of wood can be further increased.

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

  In the above embodiment, the three container bodies 10 are stacked and integrated with the band B before shipment. However, the two container bodies 10 or four or more container bodies 10 are stacked and integrated with the band B before shipment. In some cases, the band B may be hung on one cold storage container 1 and the upper lid 20 may be fixed to the container body 10 before shipment. Moreover, when shipping one cold storage container 1, you may make it ship by fixing the upper cover 20 to the container main body 10 with the uneven | corrugated fitting structure of the upper cover 20 and the container main body 10 instead of a band.

  Moreover, in the said embodiment, although the connection part 21 comprised from the flat plate part of the area which covers the upper surface opening part 10A of the container main body 10, the connection part 21 has many strip-shaped parts in the direction orthogonal to those longitudinal directions. The structure connected by the several strip-shaped part extended may be sufficient.

  Moreover, in the said embodiment, although the connection part 21 entered 10 A of upper surface opening parts of the container main body 10, and the strip-shaped part 22 contacted the upper surface of the periphery of the container main body 10, the connection part 21 was the container main body 10. The structure which contacts the upper surface of the peripheral edge of the container main body 10 without entering the upper surface opening 10 </ b> A may be used.

  Moreover, in the said embodiment, although it was set as the structure which can drain the drip generated from a fish, the water which thawed ice, etc. to the exterior of a cold storage container, the cold storage container which cannot drain to the exterior may be sufficient. In this case, an absorption sheet that absorbs drip, water that has melted ice, and the like may be provided in the cold container.

  Moreover, in the said embodiment, although every strip-shaped part 22 made the shape and magnitude | size the same, you may comprise from the strip-shaped part from which a shape and magnitude | size differ. Moreover, the interval between the adjacent strip-shaped portions 22 and 22 may be different.
