Description

  The present invention relates to a folding container.

  Conventionally, there has been known a folding container in which a long side plate is rotatably attached to an opposing long side of a rectangular bottom plate, and a short side plate is rotatably attached to an opposing short side. Yes. For example, Japanese Utility Model Publication No. 63-117725 (Patent Document 1) discloses this type of folding container. In the conventional example shown in Japanese Utility Model Laid-Open No. 63-117725, as shown in FIG. 13, the side plates 3 on the short side that form a pair in the folded state are all horizontal to the upper surface of the bottom plate 1. The side plates 2 on the long side that make a pair overlap each other in a state and are folded so as to be in surface contact with the upper surface of the side plate 3 on the short side in a horizontal state. Therefore, the bulk in the folded state can be reduced.

  By the way, in the above conventional example, the length in the direction orthogonal to the long side of the side plate 2 on the long side (that is, the length in the height direction of the side plate 2 on the long side) is on the short side of the bottom plate 1. The length in the direction perpendicular to the short side direction of the side plate 3 on the short side (that is, the length in the height direction of the side plate 3 on the short side) is shorter than about half of the length. Since it is shorter than about half of the length on the side, it can be folded compactly as described above, but the height when assembled in a box shape is low (that is, the depth is shallow) and stored. There is a problem that when a small amount is stored and a tall stored item is put, the folded container protrudes upward from the upper opening of the folded container assembled in a box shape, and the folded containers cannot be stacked vertically in the stored state.

Therefore, for example, the side plate 2 on the long side is set so that the height in a state assembled in a box shape is high (that is, the depth is deep), the storage amount is large, and a tall storage item can be stored. It is conceivable that the length in the direction perpendicular to the long side of the base plate 1 is approximately ½ or more of the length on the short side of the bottom plate 1. In the figure, reference numeral 9 denotes a horizontal shaft portion for pivotal support of the side plate 2. In the figure, the opposite horizontal shaft portions 9 on both sides have the same level.
In this case, as shown in FIGS. 12 (a) and 12 (b), the paired side plates 2 in the folded state overlap each other, and the folding height indicated by H in FIG. There is a problem that the bulk becomes high when it is transported by the mobile phone or when it is stored in a folded state.

  In addition, it is also conceivable that the pivot position of the side plate on one long side and the pivot position of the side plate on the other long side are set to different height positions. Although the side plate on one long side is longer in the height direction than the side plate on the other long side, the side plates on both long sides cannot be molded with the same mold, Both the long side plate, which has the longer side in the height direction, is tilted first, and then the side plate on the long side, which has the shorter length in the height direction, is tilted and stacked on top of it. The folding order of the side plates on the side is fixed and cannot be folded if the folding order of the side plates on the long side is reversed. Therefore, this is not practical in terms of cost and operability. Is.

Japanese Utility Model Publication No. 63-117725

  The present invention has been invented in view of the above problems, and in a folding container, the height in a state of being assembled in a box shape can be increased, the bulk in the folded state can be reduced, and it can be folded in a stable state. An object of the present invention is to provide a folding container that can be used.

  The folding container of the present invention includes a pair of first side plates 2 that are pivotably attached to a pair of opposing sides of a rectangular bottom plate 1 and a pair of pivotally attached to another pair of opposing sides. The second side plate 3 is folded with the pair of first side plates 2 folded down and the pair of second side plates 3 tilted, and the pair of second side plates 3 is erected, and then the pair of second side plates 3 is raised. 1 is a folding container in which a side plate 2 is erected and assembled into a box shape, and the pair of first side plates 2 have the same pivotal support position height, and the first side plates 2 are in a tilted state. Are partly overlapped in a surface contact state, and a part of the side plate located under the first side plate 2 that is paired in the tilted state is in contact with the upper surface side of the bottom plate 1, and the pair of first side plates 2 Of the side plate which becomes the upper side in the state of providing the dent 10 in the part which becomes the lower surface in the state of the tip of the It is configured to contact the upper surface of the tip of the lower side plate when the ridge portion 10 is tilted, and the height of the pivotal support position of the paired second side plate 3 is the same and tilted. The second side plates 3 that are paired in a state are configured to be horizontal, support both ends of the first side plate 2 in the standing state, and the first side plate 2 falls outside in the standing state. Support protrusions 4 are provided at both ends of the first side plate 2 so that the second side plates 3 forming a pair are tilted, and the support protrusions 4 at both ends are connected to the other pair of bottom plates 1. It is characterized by being in contact with receiving portions 5 provided at both end portions on the side. By setting it as such a structure, while the height of the folding container in the state assembled in the box shape can be made high, the volume in a folding state can be made low. Moreover, even though the bulk of the folding container is lowered in the folded state, the height of the pivoting support position of the overlapping pair of side plates is the same as the overlapping pair of side plates. Even if it is molded with a mold, it can be used, and the recess 10 is provided on the lower surface of the tip of the overlapping pair of side plates in a tilted state. Since the upper side plate indented portion 10 is configured to come into contact with the upper surface of the lower side plate tip when the side plate is depressed, the bulk in the folded state can be further reduced and a pair is formed when folded. Further, it can be configured such that it can be folded regardless of which of the two side plates is tilted first. Further, the second side plate 3 that is paired on the first side plate 2 that is inclined in the folded state is folded horizontally on the second side plate 3 that has the support projections 4 on both ends of the bottom plate 1. The second side plate 3 can be stably held in a horizontal state by being in contact with and supported by the receiving portions 5 provided at both ends on the long side.

  In the present invention, the pair of first side plates have the same rotational pivot support position, and the first side plates are configured to overlap each other in a surface contact state when they are in a tilted state. A part of the side plate located under the first side plate that makes a pair in contact with the upper surface side of the bottom plate, and with the tip portion of the pair of first side plates tilted down, a recess is provided on the lower surface portion. In this state, when the recessed portion of the upper side plate is tilted, it is configured to come into contact with the upper surface of the tip portion of the lower side plate, and the height of the pivotal support position of the paired second side plate is the same In addition, the second side plates that are paired in the tilted state are configured to be horizontal, support both ends of the first side plate in the upright state, and the first side plate is in the upright state in the upright state. Support protrusions are provided at both ends of the first side plate to prevent the two side plates from falling down and support the both ends while the paired second side plates are tilted down. Since the part abuts against the receiving parts provided at both ends of the other pair of sides of the bottom plate, the height of the folding container in the box-like assembled state can be increased and the bulk in the folded state can be reduced, and the distribution cost can be reduced. The folding container which can lower can be provided. Moreover, although the volume in the folded state of the folding container is lowered, the height of the pivoting support position of the overlapping first pair of side plates is the same height position, so the overlapping pair of side plates Can be used even if it is molded with the same mold, and the cost can be reduced, and the tip of the first side plate forming the overlapping pair is tilted. Since the concave portion is provided in the lower portion, and the concave portion of the side plate that is upper in the tilted state is configured to come into contact with the upper surface of the tip portion of the lower side plate, the bulk in the folded state In addition, it is possible to make it possible to fold the two side plates that are paired at the time of folding, so that the folding can be facilitated by either of the two side plates being tilted first. In addition, when the second side plates that are paired on the first side plate that is inclined in the folded state are folded in contact with each other in a line contact state in a horizontal state, the second side plate that is horizontally tilted is supported. Although it may be difficult to stabilize, the support projections at both ends of the second side plate are brought into contact with the receiving portions provided at both ends of the other pair of sides of the bottom plate so that the second side plate is stably in a horizontal state. It can be held.

  Hereinafter, embodiments of the present invention will be described.

  The folding container of the present invention includes a pair of first side plates 2 that are rotatably attached to a pair of opposing sides of a rectangular bottom plate 1 made of synthetic resin, and a pair of opposite sides that are rotatable. The pair of second side plates 3 attached to each other is folded with the pair of second side plates 3 tilted on the pair of first side plates 2, and the pair of second side plates 3 is raised. The pair of first side plates 2 is raised later and assembled into a box shape.

  The folding container has a rectangular shape when the bottom plate 1 is rectangular and when folded and becomes a rectangular box when assembled in a box shape, and when the bottom plate 1 is folded when the bottom plate 1 is square However, in the present invention, any of the above types of folding containers may be used, but the attached drawings may be used. Fig. 1 shows an embodiment in which the bottom plate 1 is rectangular. Hereinafter, an example in which the bottom plate 1 is rectangular will be described with reference to FIGS. 1 to 11. In the following description, the first side plate 2 will be described as the long side plate 2a, and the second side plate 3 will be described as the short side plate 3a.

  A long side plate 2a is rotatably attached to the opposite long side of the rectangular bottom plate 1 made of synthetic resin, and the short side of the short side of the bottom plate 1 is short. A side plate 3a on the side is rotatably attached.

  When the side plate 2a on the long side has a length in a direction orthogonal to the long side of the bottom plate 1 is approximately ½ or more of the length on the short side of the bottom plate 1, and is rotated and folded, The paired side plates 2a on the long side are partially overlapped. In the embodiment of the accompanying drawings, the side plate 3a on the short side has a length in the direction orthogonal to the short side of the bottom plate 1 shorter than about ½ of the length on the long side of the bottom plate 1. When turned and folded, the paired side plates 3a on the short side do not overlap each other.

  Both the side plate 2a on the long side and the side plate 3a on the short side are attached to the bottom plate 1 so that the lower ends thereof can be rotated by the horizontal shaft portions 9a and 9b.

  Here, the height position (the height position of the horizontal shaft portions 9a, 9a) of the respective pivotal support portions to the bottom plate 1 of the paired long side plates 2a is the same height position. Further, the height positions of the pivot portions (the height positions of the horizontal shaft portions 9b and 9b) of the paired short side plates 3a to the bottom plate 1 of the short side plates 3a are the same height position. It has become. Then, the pivot position of the short side plate 3a to the bottom plate 1 (the height position of the horizontal shaft portions 9b, 9b) and the height position of the pivot portion of the long side plate 2a to the bottom plate 1 (horizontal axis). The height positions of the portions 9a and 9a) are different from each other in height, and the height position of the pivot portion of the side plate 3a on the short side is higher than the height position of the pivot portion of the side plate 2a on the long side. In order to fold, the side plate 2a on the long side is folded and stacked on the bottom plate 1 first, and then the side plate 3a on the short side is folded and stacked on the side plate 2a on the long side. It has become.

  In the embodiment shown in the accompanying drawings, as shown in FIGS. 1A, 2, 5, 9, 10 and the like, a rising protrusion 12a is provided on the long side of the upper surface of the bottom plate 1. There is a long-side horizontal shaft portion 9a located in the recess of the rising protrusion 12a.

  Further, as shown in FIG. 1A, FIG. 2, FIG. 5, FIG. 9, FIG. 10, etc., a rising protrusion 12b is provided on the short side of the upper surface of the bottom plate 1, and the rising protrusion 12b. The horizontal axis portion 9b on the short side is located in the recess.

  The height position of the horizontal shaft portion 9a is set as follows. That is, either one of the side plates 2a on both long sides is tilted first, and the side plate 2a on the long side that has been tilted first is tilted so that the side plate 2a on the long side becomes lower, and the side plate on the long side When a part of 2a is brought into contact with the upper surface side of the bottom plate 1 and then the other side plate 2a on the other long side is tilted, the side plate 2a on the long side that has been tilted later is tilted first. The height position of the horizontal shaft portion 9a is set so that the side plate 2a on the long side is in surface contact with and overlapped. Therefore, the height position of the horizontal shaft portion 9a that satisfies the above conditions is set differently depending on the thickness of the side plate 2a on the long side and the length in the height direction.

  The height position of the horizontal axis portion 9b is set as follows. That is, the side plate 2a on the long side that is paired as described above is folded and the side plate 2a on the long side is brought into surface contact in an inclined state and overlapped, and the side plate 2a on the long side on the inclined side is overlapped. The height position of the horizontal shaft portion 9b is set so that both of the side plates 3a on the short side that make a pair can be contacted in a horizontal state.

  Support protrusions for supporting both ends of the long side plate 2a in the standing state and preventing the long side plate 2a from falling outside in the standing state at both ends of the short side plate 3a. 4 protrudes.

  Thus, in using the folding container having the above-described configuration, the container is stored and transported in a state assembled in a box shape as shown in FIGS. 8 and 9, but when not used, It is transported and stored in a folded and compact state.

  Here, when folding the folding container assembled in a box shape, first, the side plate 2a on one long side is turned by turning and tilting one of the paired side plates 2a on the long side. A part thereof is brought into contact with the upper surface side of the bottom plate 1 in an inclined state. Next, the side plate 2a on the other long side is turned and tilted so that the side plate 2a on the other long side is tilted obliquely by tilting a part of the side plate 2a on the other long side. It is something that overlaps. In this case, the long side side plates 2a constituting the pair are overlapped in a parallel state in the vertical and horizontal directions of the long side side plates 2a. That is, surface contact is made in a state where the side plates 2a on the long side constituting the pair are brought down in a surface contact state. Here, the surface contact is not only when the surfaces are in contact with each other and overlap, but also when the longitudinal and lateral ribs or grid-like ribs are formed in the longitudinal direction and the lateral direction of the side plate on the long side of one side and the other side. When vertical and horizontal ribs or grid-like ribs are in contact with each other, or when vertical and horizontal ribs or grid-like ribs are formed in the vertical and horizontal directions of the side plate on the long side, vertical and horizontal ribs or grid-like ribs are used. The ribs may come into contact with each other, and in either case, the paired long side plates 2a overlap each other in a parallel state in the vertical and horizontal directions of the long side plate 2a.

  As a result, the side plates 2a on both long sides whose heights at the pivot support positions are the same are paired obliquely as shown in FIG. 5 and FIG. In the vertical and horizontal directions of the side plates 2a on the side, they overlap each other in parallel. In this way, the pair of side plates 2a on both long sides whose heights at the pivot support positions are the same are folded so as to overlap each other in a parallel state in the vertical and horizontal directions of the side plates 2a on the long side. Thus, as shown in the schematic diagram of FIG. 11, the folding height of the side plate 2a on the long side indicated by H is approximately half or more of the length of the side plate 2a on the long side on the short side of the bottom plate 1. When the one having the length of 2 is folded, it can be shortened to the shortest, and the volume when folded is lower than that of the conventional FIGS. 12 (a) and 12 (b). When the paired long side plates 2a are folded, the pivotal support positions of both long side plates 2a are the same height, so which side plate 2a on either long side is tilted first. However, some of them can overlap each other in a surface contact state, and the folding order of the side plates 2a on both long sides can be made unrestricted.

  After the paired long side plates 2a are folded as described above, the pair of short side plates 3a having the same pivotal support position height are rotated and tilted, FIG. 2. As shown in FIG. 3, the side plate 3a on both short sides is placed in contact with the side plate 2a on the long side on the upper side plate 2a of the pair of long sides that have been folded down first in a state where the side plates 3a are tilted horizontally. It touches. In this way, the upper side plate 2a on the long side of the pair of the side plates 3a on the short side which has been paired with the same height of the pivotal support position in the state where the side plates 3a on both short sides have been tilted horizontally. By making contact with the side plate 2a on the long side, the side plate 3a on the short side can be folded to the lowest side on the side plate 2a on the long side.

  Therefore, according to the present invention, it is possible to reduce the bulk when the folding container is folded for the above-described reason, and to save as little space as possible during transportation and storage in the folded state.

  By the way, as described above, since the side plate 3 on the short side in the horizontal posture is positioned on the upper surface portion of the folding container in the folded state, the appearance is good. FIG. 10 shows a state in which the folding containers are stacked one above the other.

  Moreover, in the state which contact | abutted on the side plate 2a of the long side on the upper side plate 2a of the pair of long side which it laid down first in the state which laid down the side plate 3a of the short side horizontally as mentioned above. As shown in FIG. 1 (b), the support protrusions 4 provided at both ends of the side plate 3a on the short side are configured to contact the receiving portions 5 provided at both ends on the long side of the bottom plate 1. It is. As a result, the support projections 4 at both ends of the side plate 3a on the short side that is horizontally collapsed in a folded state are brought into contact with the receiving portions 5 provided at both ends on the long side of the bottom plate 1 to contact the short side. The side plate 3a can be stably held in a horizontal state.

  Here, when the side plates 3a on the short side that are paired on the long side plate 2a that is inclined in the folded state are brought into contact with each other in a line contact state in a horizontal state, the side plate 3a on the short side side becomes Both end portions are supported not only on the bottom plate by the support protrusions 4 but also in the intermediate portion of the short side plate 3a, so that the intermediate portion of the short side plate 3a is not bent downward. Even when a load is applied to the side plate 3a on the short side in the tilted state, the side plate 3a on the short side can be prevented from being deformed.

  On the other hand, in order to assemble in a box shape to use the folding container, first, the side plates 3a on the short side that are horizontally folded are respectively turned upright, and then the long side that is collapsed in an overlapping state. As shown in FIG. 7, the upper side plate 2a on the upper long side of the side plate 2a is turned upright, and then the remaining lower side plate 2a is turned up and turned up. It is assembled into a shape. In the state assembled in this box shape, both ends of the side plate 2a on the long side are received and supported by the support protrusions 4 in the standing state, thereby preventing the side plate 2a on the long side from falling outside in the standing state. It is like that. In the embodiment shown in the attached drawings, the support protrusion 4 also serves as the locking means 6, and the locking means 6 provided at both ends of the side plate 3a on the short side in the state assembled in a box shape are long. The locked means 7 provided at both end portions of the side plate 2a on the side are detachably locked to hold the assembled state in a box shape.

  In this way, the folding container is assembled in a box shape, and the stored items are stored and transported or stored in the box shape. In the above embodiment, the bottom plate 1 of the side plate 2a on the long side is used. Since the length in the direction orthogonal to the long side of the bottom plate 1 is approximately ½ or more of the length on the short side of the bottom plate 1, the volume of the folding container in a box-like assembled state can be further increased and deepened. It becomes deeper and can store a large amount of stored items, and even a bulky stored item can be stored so as not to jump out from the upper opening of the folding container. There is no problem even if they are stacked.

  In the present invention, the recessed portion 10 is provided in a portion that becomes the lower surface in a state in which the distal end portion of the side plate 2a on the long side is turned down. Thereby, when it falls down as shown in FIG. 1, A part of the position shifted | deviated to the pivotal support side rather than the dent part 10 of the side plate 2a of the long side which becomes lower will contact | abut on the upper surface of the bottom plate 1, and When the depression 10 of the side plate 2a on the long side that is on the upper side is tilted, it is in surface contact with the upper surface of the tip portion of the side plate 2a on the long side that is on the lower side. By forming the dent 10, the bulk when the side plate 2 a on the long side is tilted and stacked can be further reduced.
