Description

  The present invention relates to a container for transporting fruits for transporting and storing fruits such as bananas.

  2. Description of the Related Art Conventionally, a box-shaped fruit transporting container that is opened upward and includes a bottom portion and a side wall portion has been used. The container for transporting fruits is integrally formed of synthetic resin or the like, or is formed so that it can be folded and assembled by providing a side wall portion that can be raised and lowered with respect to the bottom portion (for example, Patent Document 1, Patent) Reference 2).

  There are various kinds of fruits, and for example, bananas harvested at a banana farm are often stored in a container for transporting fruits and transported.

  When transporting bananas from the production area, usually the bananas are harvested in a blue state, subjected to quality control processing such as washing, shaft processing, drying, etc., and once stored in a warehouse at around 13 ° C, a container for transporting fruits And then transported by ship, etc., and stored at around 13 ° C. after transportation to stop aging again in the warehouse. And it keeps at about 18 degreeC in the exclusive warehouse sealed before shipment, and it is made to ripen with ethylene gas. To ripen bananas, stack multiple containers for transporting fruit vertically in the warehouse and place them side by side, and ripen them by ejecting ethylene gas into the warehouse and entering the containers for transporting fruits. I try to let them. For this reason, vent holes are provided in the side wall and bottom of the container for transporting fruits.

  In this way, the hard and blue bananas before ripening are completely ripened yellow with ethylene gas before shipment, and then the fruit transport container is collected and returned (that is, a returnable box).

  By the way, when ripening bananas as described above, the speed of banana ripening varies depending on the banana production area, type, length, thickness, etc., so check the ripening condition of the banana in the container for fruit transportation There is a need to. Therefore, it is conceivable to check the inside from the vent of the side wall of the container for transporting fruits, but the vent is usually formed small and difficult to check, and if the vent is made large enough to be confirmed, Bananas (or fruits other than bananas) housed inside can easily enter the ventilation holes of the side wall, and the fruits may come into contact with and damage the tip of the peripheral edge of the ventilation holes. Therefore, it is not preferable.

In addition, the banana accommodated in the fruit transport container is most likely to come into contact with the side wall at the center in the vertical direction (that is, it is easily located outside the fruit transport container in plan view). It is easy to confirm if a confirmation opening window is drilled in the center, but if the opening window is drilled in this way, the banana is damaged by contact with the tip of the peripheral edge like the vent hole. In particular, in this case, the pointed portion is formed at the central portion in the vertical direction of the side wall portion where the banana is most likely to come into contact with the side wall portion.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a container for transporting fruits that can be well confirmed from the outside without damaging the fruit accommodated inside. It is an object to do.

In order to solve the above-mentioned problem, in the invention according to claim 1, a box-like shape having an opening formed by the bottom part B and the side wall part S is formed, and a lateral rib 22 and a longitudinal rib 23 are provided on the outer surface of the side plate 2 . in the container C for fruit transport, the right-left direction and bulge bulging portion 20a outward in the middle portion in the vertical direction of the inner surface of each side wall portion S, to form a 20b, bulge substantially central portion in the vertical direction of each side wall S When the side wall portion S is formed, the transparent window 3 having a shorter left and right width than the left and right width of the side wall portion S is formed integrally with the side wall portion S between the horizontal ribs 22 and the vertical ribs 23 in the portions 20a and 20b. The vent hole 4 is formed in a portion of the side wall portion S other than the portion where the transparent window 3 is provided , and the vent hole 4 has a density in the middle portion of each side wall portion S higher than that in the vicinity of the upper and lower end portions. It is also characterized by being made lower . By adopting such a configuration, the fruit contained in the container C can be confirmed well from the outside through the transparent window 3 without damaging the fruit housed in the container C at the tip such as an edge. Is possible.

  In this invention, it becomes possible to confirm the fruit in a container favorably from the outside through a transparent window, without damaging the fruit accommodated in a container by a pointed part like an edge.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The fruit transport container C of the present invention has a box-like shape that is formed from the bottom B and the side wall S and is open upward. There is no particular limitation as to whether or not the container can be folded. In this embodiment, the container is a folding container that can be folded and assembled. Hereinafter, a folding container as a container for transporting fruits according to the present embodiment will be described as simply container C.

  As shown in FIGS. 1 to 5, the container C includes a pair of side plates 2 attached to a pair of opposite sides of a rectangular bottom plate 1 made of a synthetic resin so as to be rotatable (a side plate 2 which is tilted first). And hereinafter referred to as the first side plate 2a) and the other pair of side plates 2 rotatably attached to the other pair of opposing sides (this is the side plate 2 to be tilted later, hereinafter referred to as the second side plate). 2b) is folded in a state where the pair of first side plates 2a is tilted and the pair of second side plates 2b is tilted, and the pair of second side plates 2b is erected, and then the pair of first side plates 2a is erected and assembled into a box shape. In this container C, as shown in FIG. 1 and the like, the bottom plate 1 constitutes a bottom portion B, and the side plate 2 and side wall portions S are constituted by rising protrusions 10a and 10b of the bottom plate 1 described later. .

  The container C has a rectangular shape when viewed from the bottom when the bottom plate 1 has a rectangular shape and is folded into a box having a rectangular shape when viewed from the top when assembled into a box shape, and a container C when the bottom plate 1 has a square shape when folded. There is a type that becomes a square in plan view and becomes a square box in plan view when assembled in a box shape, but the attached drawings show an embodiment in which the bottom plate 1 is rectangular. Hereinafter, the first side plate 2a is described as a short side plate, and the second side plate 2b is described as a long side plate. Of course, the first side plate 2a is a long side plate, and the second side plate 2b. May be a side plate on the short side.

  A side plate on the short side, which is the first side plate 2a, is pivotally attached to the opposite short side of the rectangular bottom plate 1 made of synthetic resin. A side plate on the long side which is the second side plate 2b is rotatably attached to the side.

  Here, the height position of each pivotal support portion (not shown) to the bottom plate 1 of the paired first side plate 2a is the same height position. Moreover, the height position (height position of the horizontal-axis part 21b) of each pivot part to the baseplate 1 of the 2nd side plate 2b used as a pair is the same height position. And the height position of the pivot position of the first side plate 2a to the bottom plate 1 and the height position of the pivot portion of the second side plate 2b to the bottom plate 1 are different, and the pivot of the first side plate 2a is different. The height position of the pivotal support portion of the second side plate 2b is set higher than the height position of the support portion. When folding, the first side plate 2a is first folded on the bottom plate 1, and then the rear side The second side plate 2b is folded, and the pair of second side plates 2b are stacked on the pair of first side plates 2a.

  In the present embodiment, as shown in FIG. 1, one pair of opposing sides of the upper surface portion of the bottom plate 1 is provided with a rising protrusion 10 a, and the other pair of opposing sides is provided with a rising protrusion 10 b. The rising protrusion 10b is higher than the rising protrusion 10a. The first side plate 2a is pivotally supported by the horizontal shaft portion at the rising protrusion 10a, and the second side plate 2b is pivotally supported by the horizontal shaft portion 21b at the rising protrusion 10b.

  By the way, in this embodiment, since the side plate 2 of the container C is a separate member from the bottom plate 1 and each side plate 2 is also a separate member, the side plate is compared with the side plate of an integrated container shape container in which the bottom plate and the side plate are integrated. It is necessary to increase the strength of 2. In the container C, when the side plate 2 is erected, the lower end surface portion is placed on the upper surface portion of the bottom plate 1 (in this embodiment, the rising protrusion 10a and the rising protrusion 10b provided on the upper surface of the bottom plate 1). Further, it is necessary to place the bottom plate 1 of the upper container C on the upper surface portion of the side plate 2, and for this reason, the side plate 2 of the container C has a lateral rib 22 on the outer surface of the flat plate portion 20. And the vertical rib 23 is provided.

  In this case, depending on the type of container C, if the grip hole 5 is formed only in the first side plate 2a, the grip hole 5 is formed only in the second side plate 2b. In this case, the gripping holes 5 may be formed in both the first side plate 2a and the second side plate 2b. In the present embodiment, the holding hole 5 is formed in the first side plate 2a.

  Here, in the present embodiment, the pair of first side plates 2a, which are the side plates 2 that are tilted first when folded, the first side plates 2a do not overlap with each other in the tilted state, and the side plates 2 are opposed to the bottom plate 1. The side plate 2 and the bottom plate 1 are set so as to be in contact with each other substantially in parallel or to face each other with a small gap. By comprising in this way, the volume of the container C in the folded state can be made low.

  As shown in FIG. 1 and the like, end projections for receiving both end portions of the side plate 2 that is tilted first in an upright state so as not to fall outward are received at both end portions of the second side plate 2b that is the side plate 2 that is tilted later. 24 is provided. That is, when assembled in a box shape, the end portion of the first side plate 2a comes into contact with the end protrusion 24 of the second side plate 2b so that the first side plate 2a does not fall further outward. In a state where the second side plate 2b is tilted, the end protrusion 24 comes into contact with the bottom plate 1. In this state, the second side plates 2b do not overlap each other, and further, the second side plate 2b. May be brought into contact with the first side plate 2a in a substantially parallel state, or a slight gap is formed so that the load applied from the second side plate 2b in the folded state is not related to the first side plate 2a. You may make it hook only on the baseplate 1 directly from the part 24. FIG. In any case, the volume of the folded state can be reduced by adopting the above configuration.

  The container C configured as described above is such that the pair of first side plates 2a is folded first, and then the pair of second side plates 2b is folded and folded as shown in FIG. In such a folded state, it can be stored or transported in an empty state, so that it can be stored in a compact and low bulk state or transported in an empty state.

  When assembling the container C into a box shape, put a fingertip into the holding hole 5 of the second side plate 2b, and bend the fingertip to put a finger between the periphery of the holding hole 5 of the second side plate 2b and the bottom plate 1. Then, a fingertip is hooked on a portion of the inner surface of the second side plate 2b around the grip hole 5, and in this state, the second side plate 2b is rotated to stand. Next, the upper end portion of the first side plate 2a is lifted, and the first side plate 2a is turned upright to be assembled into a box shape as shown in FIGS. As a result, both the first side plate 2a and the first side plate 2b can be erected vertically without sliding the fingertips inserted in the gripping holes 5.

  In an upright state, the end of the first side plate 2a hits the end protrusion 24 of the second side plate 2b, and in this state, the adjacent first side plate 2a and second side plate 2b are joined by an arbitrary locking means. It is locked so as to maintain a vertical standing state.

  In the present invention, the fruit accommodated in the container C stacked up and down can be well confirmed from the outside, and the fruit accommodated in the container C is not damaged. As shown in FIG. 3, a transparent window 3 is provided at a substantially central portion in the vertical direction of the side wall portion S, and a vent hole 4 is formed in a portion other than the transparent window 3.

The transparent window 3 is made of a transparent member such as a synthetic resin, and the vertical length of the transparent window 3 is approximately 1/3 to 2/3 of the vertical length of the side wall portion S at a substantially central portion in the vertical direction of the side wall portion S. The left and right widths are formed to be about 1/10 to 1/5 of the left and right widths on the short side of the side wall portion S. The transparent window 3 is integrally formed when the side wall portion S (side plates 2a, 2b ) is formed . In this embodiment, the side plate 2a on the short side is formed with two on the left and right, and the side plate 2b on the long side is formed with one on the center in the left and right.

  The transparent window 3 is formed so as to be as flat as possible so that a sharp pointed portion such as an edge is not formed on the inner surface of the transparent window 3 and the side wall S of the periphery of the transparent window 3, and is accommodated inside. When the fruit comes into contact, the sharp tip is not damaged.

  Further, in this container C, bulge portions 20a and 20b that bulge outward are formed at the middle portion in the left-right direction and the vertical direction of the inner surface of the side wall portion S, and the bulge portion 11 that bulges downward on the bottom surface of the bottom portion B. Is formed. This is because when a fruit is stored in a box-like container C opened upward, it is difficult for the fruit to be located in the corner recess between the bottom B and the side wall S and in the corner recess between the adjacent side walls S. As shown in FIGS. 3 and 4, it is easy to be positioned on the middle portion of the side wall portion S and easily contact with the middle portion in the left and right direction and the vertical direction of the side wall portion S and is easily placed on the middle portion of the bottom portion B. The side plate 2a is formed with a bulging portion 20a whose inner surface bulges outward, the side plate 2b is formed with a bulging portion 20b whose inner surface bulges outward, and the bottom plate 1 has two rows of bulging portions 11 on the short side. It is installed side by side. Thereby, when the fruit is accommodated in the container C, the inner surface of the side wall part S is positioned along the outer shape of the fruit stacked in the container C, and a strong local force is received from the side wall part S. The fruit can be stored in a natural state without any problems. In this embodiment, as shown in FIGS. 3A and 3B, the upper and lower ends of the transparent window 3 formed on the side plates 2a and 2b are on the upper and lower ends of the bulging portions 20a and 20b, and are curved. Although it is shaped, no sharp point is formed and the fruit is not damaged.

  As described above, the bottom plate 1 is provided with two rows of bulging portions 11 on the short side, and the transparent window 3 is formed at the center of each bulging portion 11 in the short side direction. In this case, in order to accommodate the bananas in the container C, it is generally performed that two rows are accommodated on the short side, so that the length of the short side of the container C is divided into approximately two banana tufts. In addition, by forming the bulging portion 11 and the transparent window 3 in the portion corresponding to each row, it is possible to accommodate the banana in a natural state as described above and to confirm the ripening condition from the transparent window 3 for each row. It becomes possible.

  Further, a vent hole 4 is formed in the container C. The vent hole 4 is an opening formed in a portion other than the transparent window 3 of the side wall portion S and the bottom portion B, and there is a risk that fruits may come into contact with and damage the edge of the peripheral edge, and the vent hole 4 is particularly large. Since the fruit easily enters the vent hole 4 and is easily damaged (the larger the opening area), the small vent holes 4 are provided at a low density in the middle portion of the side wall portion S where the fruit is easily in contact with the upper, lower, left and right ends. It is preferable to provide large ventilation holes 4 in the vicinity of the portion with high density. Thereby, it can suppress that the fruit accommodated in the inside contacts the edge of the peripheral edge of the vent hole 4 of the side wall part S, and is damaged. Further, the vent hole 4 may be chamfered at its peripheral edge to eliminate the edge and prevent the fruit from being damaged.

  By adopting the above-described configuration, the fruit contained in the container C is satisfactorily confirmed from the outside through the transparent window 3 without damaging the fruit contained in the container C at the tip portion such as an edge. It becomes possible.
