Description

  The present invention relates to an agricultural product container used for shipping and transportation of agricultural products such as vegetables and fruits, and an inner container thereof.

  As containers for the distribution of various articles, folding containers are often used to reduce the volume occupied by containers when returning containers after use. As a foldable container of this type, it is required to satisfy the requirements such as easy assembly and folding operations, durability, pressure load resistance, and the like. The shown synthetic resin foldable containers are known.

  As shown in FIG. 22, such a folding container is configured such that one of the four side plates 112, 112 and 113, 113 facing each other, for example, the side plate 112 on the long side is at the center in the height direction. The other side plate 113 opposite to each other in a direction perpendicular to this is supported so as to be pivotable in the upward upward direction with the upper end portion pivotally supported by the upper frame 114 as a fulcrum. In the state where the other side plate 113 is rotated upward, the one side plate 112 is folded on the bottom plate 111 and overlapped, so that it can be folded low.

  In recent years, foldable containers of the above-mentioned form are often used for shipping, transportation, etc. of various agricultural products such as vegetables, fruits, root vegetables, mushrooms, etc. Since thermal insulation is required, it has been proposed that constituent members such as a bottom plate and a side plate are made of a material having thermal insulation such as a synthetic resin foam as disclosed in Patent Document 1.

  By the way, in shipping, transportation, etc. of agricultural products such as broccoli, after pre-cooling in a state where agricultural products are stored in containers, they may be packed in ice and shipped for transportation. In this case, in the foldable container, water generated by melting of ice leaks, causing problems such as wetting of the transportation vehicle and the floor of the factory. Therefore, when using a folding container in which the one opposing side plate is folded in the middle for shipping and transporting agricultural products, it is easy to assemble and fold, and has heat insulation for cooling. Therefore, it is desired that the above water leakage can be prevented.

  Patent Document 2 below proposes a folding container that has a structure that facilitates assembly during use and folding during return and does not cause water leakage. In this proposed container, the lower side plate is formed integrally with the bottom plate in a container shape so as not to cause water leakage, and the upper side plate connected to the lower side plate via the hinge portion is tilted outward to lower the lower side plate. It has a structure along the line.

  However, since the lower side plate is integrally formed with the bottom plate, only about half of the container height is folded even in the folded state, so that the side plate shown in FIG. In comparison, the size of the folded state is considerably large and bulky, difficult to handle, inefficient in storage and transportation, and expensive in transportation.

The present invention provides a container for agricultural products that can be controlled, and further provides an inner container that can be suitably used for a container for agricultural products.

The present invention that solves the above problems is a flat rectangular or square agricultural product container, in which each side plate of the four sides is provided so as to be foldable, and set in the assembled container main body. An inner container, the inner container is integrally formed of a synthetic resin foam sheet, has a container shape having a storage recess recessed downward, and is formed on the bottom plate of the container body, Each side of the bottom of the molding bottom part is connected to each other via a hinge part so as to be able to stand upright. phase folding piece is folded to the inside of the side plate portion opposing are continuously provided, the folding piece is comprised is formed so as to form a state in which bent obliquely to the surface side by the hinge portion in the deployed state, the side Part is characterized in that it is loaded set in the container body in a standing state.

  According to this agricultural product container, since the inner container has moderate heat insulation, the stored agricultural product can be protected by keeping it in a cold state, especially when it is packed with ice because it has a container-shaped molded bottom. Even if the ice melts, there is no risk of water leakage, and the container body can have a net structure. Further, in storage and transportation until use, the container body can be made to have a low bulk by folding each side plate on, for example, a bottom plate and stacking a plurality of inner containers in an unfolded state. In addition, the operation of assembling the inner container into the container body during use, separation during return, and folding work can be easily performed.

In addition, the both side ends of the side plate portion of one of the opposed vertical and horizontal, through a hinge portion, folding piece is folded to the inside of the side plate portions to the other of the opposed in standing state is more Rukoto are continuously provided, the side plates In the assembled state in which the parts are erected, the adjacent side plate parts are blocked by the folding pieces, so that no large gaps are formed. Therefore, the heat insulation by the inner container is not impaired, and water leakage Can be prevented satisfactorily. In addition, the folded piece is formed so as to be obliquely bent to the surface side at the hinge portion in the unfolded state, so that when the side plate portion is erected, the folded piece is placed on the other side plate. Easy to fold inside the part and easy to assemble.

  In the above-mentioned agricultural product container, a cover plate portion covering the entire upper surface of the storage portion surrounded by each side plate portion in an upright state is connected to at least one side plate portion of the inner container via a hinge portion. It can be. For example, it is assumed that a lid plate portion covering the upper surface of the storage portion surrounded by each side plate portion in an upright state is connected to the side plate portions opposed to each other in the vertical and horizontal directions of the inner container. Can do. This makes it unnecessary to use a separate cover plate made of foamed resin, facilitates the packaging operation, and allows the top surface portion to be the cover plate portion regardless of whether or not the container body cover is attached. This keeps the lid closed and keeps heat insulation, and also prevents water and dust from entering.

  In particular, on both side ends of the lid plate portion, insertion pieces that can be inserted between the opposite side plate portions of the other side in the vertical and horizontal directions and the side plate of the container main body are connected via hinges. Preferably, this makes it possible to prevent the cover plate portion from being lifted in the use state, the cover state is maintained well, and the effect of maintaining the heat insulating property and preventing the intrusion of dust is improved.

  In the above-mentioned agricultural product container, it is preferable that inclined recesses that are inclined inward and reach the storage recesses are provided at the four corners of the peripheral edge of the molding bottom of the inner container. Thereby, in the corner part of the corner part where the standing side plate parts are brought into contact with each other, the water transmitted through the side edge of the side plate part and the folded piece enters the inclined concave part of the peripheral part of the molding bottom part, and is stored as it is. This will prevent water leakage to the outside.

  In the agricultural product container, the side surface portion of the storage recess in the molded bottom portion of the inner container has a tapered shape, and can be stacked so that the side plate portion is unfolded. As a result, a plurality of the inner containers can be stacked in a deployed state, which facilitates storage and transportation until use.

  In the simple container for agricultural products, the bottom portion of the molded bottom portion of the inner container has a convex portion that receives the stored item, and is formed so that moisture generated by the stored item can be stored in a concave portion other than the convex portion. Can be. Thereby, it can prevent that the stored agricultural product becomes wet with the accumulated water.

  In the agricultural product container, the bottom of the inner container has a semicircular cross-sectional shape and a long groove shape, and concentric semicircular protruding ribs that bulge inwardly at predetermined intervals in the longitudinal direction are formed. By doing so, a plurality of storage recesses can be provided side by side in a bellows shape in the longitudinal direction. As a result, root vegetables such as long bean can be stored without getting wet.

  In the agricultural product container, the container main body has a flat rectangular or square bottom plate and four side plates, and the opposite side plates in the vertical and horizontal directions are located on the opposite side portions of the bottom plate through hinge structures. The other side plates that are perpendicular to each other are pivotable inward and upward with the upper end as a support shaft. In a state where the other side plates are pivoted inward and upward, the one side plate is folded at the center and folded on the bottom plate, and the other side plate is placed on the side plate. It is characterized by being overlaid. This facilitates assembly and folding of the container body.

The present invention also includes a flat rectangular or square molded bottom part formed in a container shape having a storage recess recessed downwardly formed by a synthetic resin foam sheet, and a hinge part on each of the four sides of the molded bottom part.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  The container A for agricultural products of the present invention is a flat rectangular or square container, and is mainly provided with four side plates 12, 12; 13, 13 which are opposed to each other vertically and horizontally so as to be foldable on the bottom plate 11. The container main body 10 and the inner container 20 loaded and set in the assembled container main body 10.

  In the first embodiment shown in FIGS. 1 to 10, the container body 10 has basically the same structure as a conventional folding container in which one opposing side plate is folded halfway. Each component of the square bottom plate 11, the four side plates 12, 12; 13, 13, and the planar rectangular or square upper frame 14 is individually molded from a synthetic resin material and connected and configured as follows. ing.

  Of the four side plates 12, 12; 13, 13, one of the side plates facing each other in the vertical and horizontal directions, for example, in the case of a flat rectangle, the long side plate 12 is hinged to the opposite side of the bottom plate 11 as shown in the figure. 15 is connected to be able to be bent inwardly through 15, and the upper side plate 12 a and the lower side plate 12 b are connected to each other in the middle in the height direction through a connecting portion 16 having a hinge structure so that they can be bent inward. Is formed. Further, the upper end portions of the both side plates 12 are connected to the upper frame 14 via a hinge portion 17 so as to be bent.

  Also, among the four side plates 12, 12; 13, 13, in the case of the other side plates opposite to each other in the vertical and horizontal directions orthogonal to the side plate 12, for example, in the case of a planar rectangle, the side plates 13, 13 on the short side are respectively shown in the figure. The upper end is pivotally supported by the upper frame 14, and in the assembled state, the lower end is latched by the latching portion 19 at the end of the bottom plate 11 and held in a suspended state, and the pivotal support (not shown) ) Is supported so as to be pivotable in the direction of jumping inward. As a result, in the state in which the both side plates 13 and 13 are suspended, the one side plates 12 and 12 are prevented from being folded, and the assembled state is maintained, and the both side plates 13 and 13 are turned inward and upward. By making it move, the one side plate 12, 12 is folded at the center and folded on the bottom plate 11, and the other side plate 13, 13 is overlaid on the side plate 12, 12. Can be done. In addition, in order to hold | maintain the said assembly state, the locking means (not shown) which prevents the inward rotation of the said side plate 13 can also be provided.

  The inner container 20 is integrally formed with a synthetic resin foam sheet in an unfolded state, has a container shape having one or a plurality of storage recesses 21 recessed downward, and the bottom plate 11 of the container body 10. A flat rectangular or square shaped bottom 22 placed on the top, and four side plate portions 25, 25 and 26 connected to the four sides of the shaped bottom 22 via hinges 23 and 24, respectively. 26 and is formed so as to be loaded and set along the inside of the side plates 12 and 13 in the container body 10 in a state where the side plate portions 25 and 26 stand up.

That is, in the inner container 20, the vertical and horizontal dimensions of the outer shape of the molded bottom portion 22 and the standing outer shapes of the side plate portions 25 and 26 are set to be slightly smaller than the vertical and horizontal dimensions inside the container body 10, and each side plate portion In a state where 25 and 26 are erected, the container can be set inside the container body 10. Usually, the molding bottom portion 22 is recessed inwardly leaving a flange-like peripheral portion 22a that forms the opening edge of the storage recess 21, and the hinge portion 23, The side plate portions 25 and 26 are connected to each other through 24.

  In the case of this embodiment, one of the side plate portions 25 and 26, which are opposite to each other in the vertical and horizontal directions, for example, in the case of a flat rectangular shape, is hinged at both ends of the side plate portion 25 on the long side as shown in the figure. 27, a folded piece 28 that is folded inside the other side plate 26 facing the other side, for example, is connected in the standing state, and a corner between the adjacent side plates 25, 26 standing in the assembled state. The part can be shielded.

  Further, of the side plate portions 25, 26, one of the side plate portions of the side plate portion 25 on the long side facing each other, for example, and the other side plate portion 26, for example, on the short side facing each other perpendicular to the side plate portion 25. The side end portion is provided with engagement means for engaging with each other in a vertically standing state and holding the standing state. The engaging means can be implemented in various forms that can hold the side plate portions 25 and 26 in an upright state regardless of the presence or absence of the folding piece 28. In the case of the embodiment shown in the figure, the folded piece 28 connected to both side ends of the side plate portion 25 on the long side and the side end portion of the side plate portion 26 on the other short side are engaged with each other in the standing state. An engaging hole 29a and an engaging convex portion 29b are provided. In the illustrated example, an engagement hole 29 a is provided in the folding piece 28, and an engagement convex portion 29 b that can be fitted into and engaged with the engagement hole 29 a is provided at a side end portion of the other side plate portion 26. Yes.

  Thereby, in a state where the side plate portions 25 and 26 stand up, the side holes 25a and 26 are excessively tilted inward by being engaged and connected by the engagement holes 29a and the engagement convex portions 29b. It can prevent and can keep a standing state satisfactorily, and it can prevent that a big clearance gap is produced in the corner part between the adjacent side-plate parts 25 and 26 by the said folding piece 28, and can prevent a heat insulation fall. It is also effective in preventing water leakage from the corner.

  For each of the hinge parts 23, 24 and the hinge part 27, a synthetic resin foam sheet of a constituent material is heated and pressed into a V-shaped groove shape from the surface side which becomes the folding side, and is made into a predetermined thickness by resinization and thinning. It is formed so that it can be bent within the range of the V-shaped groove opening angle while maintaining the hinge strength. For example, the hinge portions 23 and 24 can be erected so that the side plate portions 25 and 26 do not fall inward excessively by setting the opening angle of the V-shaped groove to 90 °. Therefore, the side plate portions 25 and 26 can be satisfactorily held in an upright state by being inserted into the container main body 10 without the engaging means as in the embodiments described later.

The folding piece 28 is in the unfolded state until use is also possible to be formed the hinge portion 27 to be on the side plate portion 25 flush with the case of the present invention, as in the embodiment shown In the unfolded state, the hinge portion 27 is formed so as to be bent obliquely on the surface side, and when the one side plate portion 25 and the other side plate portion 26 provided with the folding piece 28 are erected, The folding piece 28 is easily folded inside the side plate portion 26. For example, when the side plate portion 25 is erected substantially vertically with respect to the molding bottom portion 22, the side plate portion 26 is assembled so as to be dropped from above into the assembled container body 10, whereby the other side plate portion 26 is opened to the container body 10. At the same time, the folded piece 28 is folded inside the side plate portion 26.

  The folded piece 28 is usually cut at an edge on the corner portion side to make it easier to bend the inside of the side plate portion 26. During the assembling work into the container body 10, the corner portion 28 a where the oblique edge and the outer edge meet is in contact with the other side plate portion 26 and rubbed against the side plate portion 26 as shown in the figure. It is desirable to form a guide groove 30 for guiding the corner portion 28a. In addition, the corner portion 28a can be rounded to suppress rubbing with the side plate portion 26. Further, in order to prevent water leakage from the corner portion, there is a case where it is not cut obliquely as in the fourth embodiment described later.

  Reference numeral 31 in the drawing denotes a rib-like convex portion for restricting and reinforcing warpage and bending deformation of the side plate portions 25 and 26, and has a convex shape on the inner side in the assembled state. The shape and arrangement of the rib-shaped convex portions 31 are not limited to those shown in the drawings, and can be implemented in various forms.

  As shown in the figure, the molding bottom 22 is formed such that the four side surfaces 32 forming the storage recess 21 are tapered and can be stacked in a state where the side plates 25 and 26 are unfolded. When handling, a plurality of inner containers 20 are stacked to reduce the bulk so that they can be handled.

  The bottom surface portion 33 of the molded bottom portion 22 has a concave and convex shape having a convex portion 33a that receives a stored item such as an agricultural product and a concave portion 33b that can store water generated by the stored item. It is possible to reinforce the bottom surface portion 33 and to prevent the stored item from coming into contact with the water accumulated in the concave portion 33b. In the case of the embodiment shown in FIGS. 1 to 10, the concave stripes and the convex stripes in the direction along the long side are alternately arranged in parallel in the direction along the short side to form an irregular shape.

  The shape of the bottom surface portion 33 can be implemented by various uneven shapes including a convex portion serving as a reinforcement and receiving a farm product to be stored and a concave portion serving as a water reservoir. For example, as shown in FIG. 11 (a) or (b), quadrangular convex portions 33b are formed in parallel in the vertical and horizontal directions so as to leave the concave portions 33b serving as ribs in a vertical and horizontal lattice pattern, The hexagonal convex portion 33b can be formed so as to leave the concave portion 33a, or can be formed in the same shape as the concave portion and the convex portion, with the concave and convex portions being reversed.

  Moreover, as a form of the said shaping | molding bottom part 22, in addition to forming the whole as one storage recessed part 21 like FIGS. 1-10 and FIG. 11, according to the kind and form of the agricultural products used as storage object, A plurality of storage recesses suitable for storage can be formed.

For example, in the case of the embodiment of FIGS. 12 and 13, the molded bottom 22 is semicircular in cross section and has one side in the vertical and horizontal directions, for example, a long side, so as to be suitable for storing the root vegetables such as long bean and lotus root. A plurality of storage recesses 34 each having a long groove shape in the direction along the side are arranged in parallel at a required interval at the inward portion leaving the peripheral edge portion 22a . The storage recess 34 is provided with concentric semicircular convex ribs 35 bulging inward at predetermined intervals in the longitudinal direction, and the concave ribs 36 between the convex ribs 35 and the respective convex ribs. Thus, the entire storage recess 34 has a bellows shape in the longitudinal direction.

  As long as the protruding ribs 35 have a concentric semicircular shape, the storage recess 34 may have a trapezoidal, semicircular, or arcuate cross section in the longitudinal direction. A cross-sectional shape having a round top at the top, for example, as shown in the figure, having a round cross-sectional triangle is preferable so that the contact area with the class B is as small as possible and the root vegetables are not damaged. . The height and arrangement pitch (interval) of the ridge ribs 35 can be appropriately set according to the type of agricultural product to be stored.

  In addition, since the container A for agricultural products requires cold storage, it is usually made of a synthetic resin foam sheet that covers the upper opening of the inner container 20 in the assembled container body 10 as shown in FIGS. And a lid 50 made of a synthetic resin molding that covers the upper opening of the container body 10. The lid 50 is provided so as to be fitted to the upper frame 14 of the container body 10. Depending on the type of agricultural product to be stored, one or both of the lid plate 40 and the lid 50 may not be used. Further, as in the embodiments described later, a lid plate portion in place of the lid plate 40 can be integrally formed with the inner container 20.

  Furthermore, although the container main body 10 of the above-mentioned Example has shown the example which consists of a board | plate material in which each structural member of the baseplate 11 and each side plate 12 and 13 was shape | molded, respectively, these baseplate 11 and side plate 12, 13 at least one component member, preferably each component member is formed with a portion of a notch (not shown) for stealing meat, or a large number of through holes as long as the strength as a container is not reduced. Using a perforated plate having a mesh or a plate material formed so as to have a net structure, it can be configured to be foldable in the same manner as described above. One example is shown in FIG.

  In FIG. 14, components and members that perform substantially the same configuration or function as the container main body 10 of the above-described embodiment are denoted by the same reference numerals. In the example of FIG. 14, the bottom plate 11 has a lattice shape with vertical and horizontal bars 11 c, and one opposing side plate 12 (upper side plate 12 a and lower side plate 12 b) and the other opposing side plate 13 are respectively The figure shows a case in which it is made of a plate material formed in a lattice shape by vertical and horizontal bars 12c and 13c, and oblique reinforcing bars 12d and 13d arranged in each grid so as to form a net structure as a whole. Also in this case, the upper side plate 12a and the lower side plate 12b of one side plate 12 are connected in a folded state on the bottom plate 11 with the connecting portion 16 in a folded state, and the other side plates 13 and 13 are further turned inward and upward. The side plates 12 and 13 are folded on the bottom plate 11 in the same manner as in the above-described embodiment. In the case of using a lid, the lid can also have a similar net structure.

  When the container main body 10 of this embodiment is used, not only the weight of the entire container can be reduced and the material can be saved, but also the inner container 20 made of the synthetic resin foam sheet described above is used by being charged. By doing this, the inner container 20 can exhibit the heat insulation effect and water leakage prevention effect necessary for the protection of agricultural products, and the protection can be made well.

  The state of use of the agricultural product container A of the present invention having the above-described configuration will be described. In handling such as storage and transportation until use, the container main body 10 and the inner container 20 are separated, and the container main body 10 is placed on the bottom plate 11 with one opposing side plates 12 and 12 being folded. And the other side plates 13 and 13 facing each other can be folded to a low bulk. In addition, the inner container 20 can be handled in a reduced state by stacking a plurality of sheets in the unfolded state. Similarly, the lid plate 40 and the lid body 50 can be handled by overlapping and reducing the bulk. Therefore, it is possible to increase the storage and transportation efficiency of the container until use.

  In use, as shown in FIG. 6, the container body 10 is assembled in such a state that the four side plates are perpendicular to the bottom plate 11. The container 20 is inserted and set from above.

  For example, as shown in FIG. 6, the side plate portions 25, 25 on one side (long side) of the inner container 20 are held upright vertically with respect to the molding bottom portion 22, so Insert it in the same way as 10. At this time, the other (short side) side plate portions 26, 26 are pushed by the opening of the container body 10 to stand up around the hinge portion 24, and at the same time, the hinge portion 27 is placed at the side end of the side plate portion 25. Folding pieces 28 that are connected to each other and are inclined to the front surface side are folded inward by being pushed by the side plate portion 26. In particular, by having the guide groove 30 in which the corner portion 28a on the corner portion side is guided, it can be folded without being caught. At the same time as the folding, the engaging projections 29b of the other side plate portion 26 are fitted and engaged with the engaging holes 29a of the folding piece 28, whereby the side plate portions 25 and 26 are engaged. The side plates 25 and 26 are held in a connected state, are well held in an upright state, and are loaded and set along the side plates 12 and 13 of the container body 10. In this way, the inner container 20 can be easily set by a one-touch operation.

  And in the set state, the agricultural products to be stored are stored inside, pre-cooled if necessary, and then packed in ice, and the upper opening is covered with the cover plate 40 and the cover body 50 and put into a packaged state. Hold, ship and transport. At this time, since the inner container 20 made of the synthetic resin foam sheet has heat insulation properties, the stored agricultural products can be kept in a cold state, and the agricultural products can be well protected. In particular, since the molded bottom portion 22 of the inner container 20 has a container shape, water does not leak even when the ice melts when stuffed with ice. Never get wet. Further, the use of the inner container 20 can exhibit the heat insulation necessary for protecting agricultural products and the effect of preventing water leakage, so that it is also possible to use a container body made of a plate material having a net structure.

  Further, when returning the container from the transportation destination (consumption place) for repeated use, the container body 10 can be easily folded to a low bulk by extracting the inner container 20 from the container body 10. That is, as shown in the figure, for the container body 10 in which one side plate 12 is folded, as shown in FIG. 10, the other side plate 13 is pivoted inward and the one side plate 12 is centered. It is possible to fold the bottom plate easily and at a low bulk like a container in which the conventional side plate is folded, by folding it at the center and folding it on the bottom plate 11 and further overlapping the other side plate 13 on the side plate 12. By returning the container body 10 and the lid 50 folded in this way, the transportation cost for the return can be reduced.

  In addition, about the separated inner container 20, it can also be returned in an expanded state, but it is formed from a synthetic resin foam sheet and is relatively inexpensive. These can be made disposable, and can also be collected and used as recycled raw materials.

  FIGS. 15-21 has shown the other Example which changed the form of the inner container 20 of the container for agricultural products. In this embodiment, the basic configuration is the same as that of the first embodiment described above, and the same components and components that perform the same function are denoted by the same reference numerals and detailed description thereof is omitted.

  The inner container 20 of this embodiment is also integrally molded with a synthetic resin foam sheet in a deployed state, and has a flat rectangular molded bottom portion having a storage recess 22 recessed downward leaving a flange-shaped peripheral edge 22a. 21 and four side plate portions 25, 25 and 26, 26 connected to each side of the four sides of the molding bottom portion 21 via hinge portions 23 and 24, respectively, so that the side plate portions 25 and 26 are connected to each other. In the upright state, the container body 10 is formed so as to be loaded and set along the inside of the side plates 12 and 13.

  In the case of this embodiment, there is no engaging means for engaging and connecting adjacent side plate portions 25 and 26 in the standing state, but one of the side plate portions 25 and 26 facing each other in the vertical and horizontal directions, For example, as shown in the figure, on both side ends of the side plate portion 26 on the short side, via hinge portions 27, respectively, the other side plate portion facing each other in the standing state, for example, the inside of the side plate portion 25 on the long side side as shown in the drawing Folding pieces 28 are connected to each other so that the corner portions between the side plate portions 25 and 26 standing up in the assembled state can be shielded. In particular, the edge on the corner portion side of the folding piece 28 is formed so as to be parallel to the peripheral edge portion 22a of the molding bottom 22 in the assembled state in which the side plate portions 25 and 26 are erected. It is formed so that the water flowing through the corners does not collect in the corners.

  That is, when the edge on the corner portion side of the folding piece 28 is inclined as in the embodiments of FIGS. 1 to 10, 11, and 12, the water flowing through the folding piece 28 flows into the corner portion. Therefore, it is desirable that the side plate portions 25 and 26 are formed so as to be parallel to the peripheral edge portion 22a of the molded bottom portion 22 in the assembled state where the side plate portions 25 and 26 are erected as described above.

  Like the above-described first embodiment, the folding piece 28 is formed so as to be obliquely bent to the surface side by the hinge portion 27 in the unfolded state, as in the first embodiment described above. When the one side plate portion 26 and the other side plate portion 25 having the folding piece 28 are erected, the folding piece 28 is easily folded inside the side plate portion 25.

  Further, each side plate portion 25 in an upright state via the hinge portions 37 and 37, respectively, on the side plate portions opposite to each other in the vertical and horizontal directions of the inner container 20, for example, the side plate portions 25 and 25 on the long side as shown in the figure. , 26 are provided with flap-shaped lid plate portions 38, 38 which can cover the entire upper surface of the storage portion mainly half by half. Although the covering ratio of the cover plate portions 38 and 38 may be different, in practice, it is preferable to cover the entire upper surface half by half as shown in the figure. In any case, the end edge portion 38a of the lid plate portion 38 is formed to have a phase-out shape as shown in FIG. 21, and a gap is generated by fitting the end edge portions 38a, 38a. It is preferable to form it so that it can be closed without being closed. Of course, a part of them may be overlapped or simply matched. Further, although not illustrated, it is also possible to carry out by connecting one lid plate portion covering the entire upper surface of the storage portion to one side plate portion. In practice, it is preferable to form the halves so as to cover each half as described above, so that only one of the cover plate portions 38 can be opened at the time of internal confirmation or the like, which is preferable from the viewpoint of maintaining a cold insulation effect.

  On both side ends of the lid plate portion 38, it is inserted between the opposite side plate portions in the vertical and horizontal directions or one of the opposite side plate portions, for example, the side plate portion 26 on the short side and the side plate 13 of the container body 10 via the hinge portion 41. An insertable piece 39 that can be inserted is provided continuously so that the cover plate portion 38 can be prevented from being lifted in use. When one cover plate part is connected to one side plate part, an insertion piece to be inserted between the opposite side plate part and the side plate capital is provided on the edge opposite to the connection side of the cover plate part. You just have to set up.

  The lid plate portion 38 is provided with rib-like convex portions 42 for restricting and reinforcing warpage and bending deformation. Contrary to the rib-shaped convex portions of the side plate portions 25 and 26, the rib-shaped convex portions 42 are convex on the outside of the container (the upper side in the closed state). Will not accumulate.

Further, in the case of this embodiment, inclined recesses 45 are provided at the four corners of the peripheral edge portion 22a of the molding bottom portion 22 of the inner container 20 so as to be inclined inward and reach from the peripheral edge portion 22a to the inner storage recess 22. It has been. As a result, water flowing along the side edges of the side plate portions 25, 26, the edge of the folded piece 28, and the hinge portion 27 at the corners of the corner portions where the edges of the standing side plate portions 25, 26 abut each other. It enters into the inclined concave portion 45 of the peripheral edge portion 22 a of the molding bottom portion 22 and flows into the storage concave portion 21.

Incidentally, the form of the housing recess 21 of the molded bottom portion 22 in this embodiment, in the first embodiment described above and can be carried in the same manner, it is also possible in the form of FIG. 11及beauty Figure 12.

  As for the container body 10 used in combination with the inner container 20, it is also possible to use the foldable container body 10 similar to the first embodiment (FIGS. 1 to 10) described above, as shown in FIG. A container body 10 having a net structure can also be used. 20 and 21 illustrate the case where the container body 10 having a net structure is used.

  The usage state of the container A of this embodiment will be described. In handling such as storage and transportation until use, the container main body 10 can be folded low in bulk like the first embodiment described above, and the inner container 20 can be folded in a deployed state. It can be handled with a low bulk. In use, as shown in FIG. 20, the container main body 10 is assembled in such a state that the four side plates are perpendicular to the bottom plate 11. The container 20 is inserted and set from above.

  That is, as shown in FIGS. 20 and 21, the side plate portions 26 and 26 on one side (for example, the short side) of the inner container 20 are erected vertically with respect to the molding bottom portion 22, and the lower molding bottom portion is formed. The battery 22 is loaded into the container body 10 from 22. At this time, the other (long side) side plate portions 25 and 25 are pushed by the opening of the container body 10 and stand up around the hinge portion 23, and at the same time through the hinge portion 27 at the side end of the side plate portion 26. The folded pieces 28 connected in this manner are folded inward by being pushed by the side plate portion 25. As a result, the side plate portions 25 and 26 are held upright and loaded and set along the side plates 12 and 13 of the container body 10.

  And in the set state, the agricultural products to be stored are stored inside, pre-cooled as necessary, and then filled with ice, the lid plate portion 38 is folded inward from the hinge portion 37, and the inserted piece 39 is inserted between the side plate portion 26 and the side plate of the container body 10 to hold the upper surface portion in a closed state. Further, if necessary, the container body 10 is covered with a lid, held in a packaged state, shipped and transported.

  At this time, since the inner container 20 made of a synthetic resin foam sheet has heat insulation properties, the stored agricultural products can be kept in a cold state, and the agricultural products can be well protected. In particular, in the case of this embodiment, since the inner container 20 is closed by the lid plate portion 38, even if the container body lid is opened during transportation, the heat insulation is not impaired, and water And dust can be prevented.

  Moreover, since the molded bottom portion 22 of the inner container 20 has a container shape, water does not leak even if the ice melts when it is filled with ice. In addition, since the inclined concave portion 45 is formed in the corner portion of the corner portion where the standing side plate portions 25 and 26 are brought together, the side portion of the side plate portion 25 and the folded piece 28 are transmitted in the corner portion. Water will not enter the corner of the peripheral edge 22a of the molding bottom 22 but will enter the inclined recess 45 and flow into the storage recess 21 as it is, and water leakage from the corner of the corner to the outside of the inner container can be prevented. As a result, the storage location and the floor of the transport vehicle are not wetted.

  In addition, when there is a possibility that dew condensation may occur on the outer surface of the inner container 20 made of a synthetic resin foam sheet during use in summer, water absorption is performed in the container body 10 of the agricultural product container A, particularly on the bottom and side surfaces. A sheet material or other water-absorbing material that can absorb condensed water, such as a sheet containing a conductive resin or a nonwoven fabric, may be inserted.

  The inner container 20 of each embodiment described above can also be used in combination with a container body that is not foldable, and even in that case, the effects described in each embodiment by using the inner container can be similarly achieved. become.

  As a synthetic resin foam sheet which is a constituent material of the inner container 20 of each of the above-described examples, polystyrene resin, polyolefin resin such as polypropylene, polyethylene and cross-linked polypropylene resin, high density polyethylene resin, polyester resin, polychlorinated resin Various thermoplastic synthetic resin foam sheets having a suitable elasticity such as a vinyl resin and a necessary shape-retaining strength in use can be used. From the viewpoint of shape retention and cost, a polystyrene resin foam sheet is preferably used.

  Although the thickness of the foamed sheet varies depending on the material used, it is usually 1 mm or more in thickness, preferably 10 mm or less, more preferably in the range of 1 to 6 mm, can be molded, and is a container. When the main body 10 is loaded and set, a thickness having a shape retaining strength that does not bend the side plate portions 25 and 26 is used. For example, in the case of a polystyrene-based resin foam sheet, about 1 to 5 mm is preferable, and a foam sheet having an expansion ratio or density of about 5 to 15 times is preferably used.

  The inner container 20 is formed in the expanded state of the above-described form by means such as vacuum forming using a mold using the synthetic resin foam sheet as a raw material.
