Further, the transport container of the present embodiment is detachably attached with a partition plate 9 capable of partitioning the storage space S1 on the bottom plate 1. The vertical direction used in the text is based on the state in which the bottom plate 1 is placed face down.

Hereinafter, the configurations of the respective members 1, 2, 3, 4, and 9 will be described in more detail.

First, the bottom plate 1 will be described.

The bottom plate 1 has a rectangular outer shape, and has two lateral grooves 12 on the upper surface thereof. Each lateral groove 12 is a portion for inserting the locking portion 95 (see FIG. 7) of the partition plate 9.

Hereinafter, the direction parallel to the short side of the bottom plate 1 is referred to as the first direction D1, and the direction parallel to the long side of the bottom plate 1 is referred to as the second direction D2.

Each of the two lateral grooves 12 is formed parallel to the first direction D1. The two lateral grooves 12 are located at a distance from each other in the second direction D2.

Each lateral groove 12 has a linear outer shape in the first direction D1 in a plan view, and the end portions 125 on both sides of the first direction D1 are formed wider than the other portion 127 located between them. ing. A plurality of drain holes 13 are formed at the bottom of each lateral groove 12 at a distance in the first direction D1. Specifically, a plurality (two) drain holes 13 are formed at the end portions 125 on both sides and the other portion 127, respectively, with a distance in the first direction D1 (see FIG. 1).

Next, the mouth frame member 2 will be described.

The mouth frame member 2 is formed in a rectangular frame shape by a pair of short side portions 28 parallel to the first direction D1 and a pair of long side portions 29 parallel to the second direction D2.

Vertical grooves 21 that open inward and upward are provided at four locations on the inner surface of the mouth frame member 2. Specifically, in one of the long side portions 29, vertical grooves 21 are formed at two locations separated by a distance in the second direction D2. Also in the other long side portion 29, vertical grooves 21 are formed at two locations separated by a distance in the second direction D2.

The vertical grooves 21 of the mouth frame member 2 at four positions are paired with each other. That is, two pairs of vertical grooves 21 are provided on the inner surface of the mouth frame member 2 so as to face each other.

The pair of vertical grooves 21 are arranged in a straight line along the first direction D1 with respect to one of the two horizontal grooves 12 of the bottom plate 1. In a plan view, the vertical grooves 21 are located on both sides of the first direction D1 of each of the horizontal grooves 12 of the bottom plate 1.

Further, the mouth frame member 2 is provided with protrusions 23 protruding upward at four locations. As shown in FIGS. 3 and 5, the portion where the protrusion 23 protrudes is the portion above the vertical groove 21 on the upper surface of the long side portion 29.

The protrusion 23 has a U-shaped structure in a plan view having a groove 231. The groove portion 231 is a groove that opens inward, upward, and downward in the first direction D1. The groove portion 231 communicates with the vertical groove 21 located directly below the groove portion 231 in a straight line in the vertical direction.

The lower portion of the groove portion 231 has a horizontal cross section substantially the same as that of the vertical groove 21 below the groove portion 231. The upper portion of the groove portion 231 has a structure that gradually expands so as to have a larger horizontal cross section toward the upper side.

A pair of inner surfaces of the groove portions 231 facing each other in the second direction D2 form a pair of guide surfaces 235 that guide the convex end portion 93 (see FIG. 7) of the partition plate 9 toward the vertical groove 21.

The upper portion of the pair of guide surfaces 235 is an inclined surface inclined in a direction away from each other (to face diagonally upward) so that the distance from each other increases as the distance from the vertical groove 21 increases.

In the present embodiment, the upper portion (upper half portion) of the pair of guide surfaces 235 is an inclined surface, but the entire guide surface 235 may be an inclined surface. The pair of guide surfaces 235 may be configured such that at least the upper portions thereof are separated from each other toward the upper side.

The shape of the protrusion 23 may be any shape as long as a pair of guide surfaces 235 are provided at a distance in the second direction D2, and is not limited to a U-shape in a plan view.

Further, in the present embodiment, the vertical groove 21 is formed up to about half of the vertical dimension of the mouth frame member 2, but for example, it is formed over the entire vertical dimension of the mouth frame member 2 so as to open downward.

Further, each of the pair of long side portions 29 included in the mouth frame member 2 is provided with a support shaft portion 25 for rotatably supporting the lid plate 4. The support shaft portion 25 includes a plurality of pins 252 arranged along the second direction D2 and a plurality of pin receivers 254 (see FIGS. 3 and 5). The pin 252 and the pin receiver 254 are respectively projected upward from the long side portion 29. The protrusion 23 is located between two pin receivers 254 arranged at a distance in the second direction D2 (see FIG. 3).

Next, the side peripheral wall 3 will be described.

The side peripheral wall 3 is formed by a pair of short side plates 32 and a pair of long side plates 34 in a rectangular shape in a plan view. The entire circumference of the storage space S1 formed above the bottom plate 1 is surrounded by a pair of short side plates 32 and a pair of long side plates 34 connected in a rectangular shape in a plan view.

The upper end portions of the pair of short side plates 32 are rotatably connected to the pair of short side portions 28 of the mouth frame member 2 on a one-to-one basis. The lower end portions of the pair of short side plates 32 are detachably locked one-to-one with respect to the pair of short side end portions of the bottom plate 1.

The upper end portions of the pair of long side plates 34 are rotatably connected to the pair of long side portions 29 of the mouth frame member 2 on a one-to-one basis. The lower end portions of the pair of long side plates 34 are rotatably connected to the pair of long side end portions of the bottom plate 1 on a one-to-one basis.

Each long side plate 34 is composed of an upper plate 341 and a lower plate 342. The upper plate 341 and the lower plate 342 are rotatably connected to each other so that they can be bent inward in a dogleg shape.

In the present embodiment, the inner surface of the side peripheral wall 3 is not formed with a vertical groove into which the partition plate 9 is inserted, but a vertical groove that communicates with the vertical groove 21 in a straight line vertically may be further formed. In this case, the convex end portion 93 of the partition plate 9 can be inserted into the vertical groove of the side peripheral wall 3 through the vertical groove 21.

Next, the lid plate 4 will be described.

The transport container of the present embodiment includes a pair of lid plates 4. FIG. 2 and the like show a fully open state of the pair of lid plates 4. When both of the pair of lid plates 4 are in the fully closed state (not shown), the pair of lid plates 4 close the upper opening of the storage space S1 in a posture in which the end edges thereof are overlapped with each other.

The lid plate 4 is a rectangular plate-shaped member having the second direction D2 as the longitudinal direction, and has a support shaft portion 41 rotatably connected to the mouth frame member 2 at the end edge portion on the long side side thereof. The support shaft portion 41 includes a plurality of pins 412 arranged along the second direction D2 and a plurality of pin receivers 414 (see FIG. 3).

Each pin 412 on the lid plate 4 side is pivotally supported by the pin receiver 254 on the mouth frame member 2 side, and each pin 252 on the mouth frame member 2 side is pivotally supported by the pin receiver 414 on the lid plate 4 side. As a result, the lid plate 4 and the mouth frame member 2 are rotatably connected to each other's support shafts 41 and 25.

In the present embodiment, the two lid plates 4 are provided so as to close the upper opening of the storage space S1, but for example, one lid plate 4 may be provided so as to close the upper opening of the storage space S1.

As shown in FIG. 2, on the back surface of the lid plate 4 (the surface facing downward in the fully closed state), regulation ribs 45 are provided at two locations at a distance in the second direction D2.

The regulating rib 45 is formed so as to project downward in the fully closed state, and when the protruding portion hits the partition plate 9 in the fully closed state, deformation of the partition plate 9 in the second direction D2 is restricted. .. In particular, the contents may strongly push the partition plate 9 during transportation, and the regulation rib 45 also suppresses the deformation of the partition plate 9.

It is preferable that the regulating rib 45 hits the central portion of the partition plate 9 in the first direction D1 in order to suppress the deformation of the partition plate 9. Since the transport container of the present embodiment is a type of container in which the upper opening of the storage space S1 is closed by a pair of lid plates 4, the portion of the pair of lid plates 4 that is close to each other in the fully closed state is restricted. The rib 45 is provided. If the container is of a type in which the upper opening of the storage space S1 is closed by one lid plate 4, it is preferable to provide the regulation rib 45 in the central portion of the first direction D1 of the lid plate 4.

Next, the partition plate 9 will be described.

As shown in FIG. 7, the partition plate 9 is a rectangular plate-shaped member as a whole, and a rectangular piece-shaped locking portion 95 elongated in the first direction D1 from the central portion of the lower end edge of the first direction D1. However, it protrudes downward. From both sides of the upper end portion of the partition plate 9 in the first direction D1, rectangular protrusion-shaped convex end portions 93 project outward in the first direction D1. The pair of convex end portions 93 of the partition plate 9 project in a direction away from each other.

The partition plate 9 can be formed of synthetic resin or can be formed of paperboard such as corrugated cardboard.

In particular, the lateral groove 12 provided in the bottom plate 1 of the present embodiment is provided with 125 at both ends wider than the others, so that when the partition plate 9 is made of corrugated cardboard, it is advantageous when it is used repeatedly. Is.

That is, in general, corrugated cardboard is a material whose corners are easily turned up when used repeatedly, but even if the corners of the corrugated cardboard locking portion 95 are turned up to some extent, it corresponds to both corners of the locking portion 95. Since both end portions 125 are formed to be wide, the ease of insertion is ensured.

As described in detail with reference to FIGS. 1 to 7, the transport container of the present embodiment includes a rectangular plate-shaped bottom plate 1 and a rectangular frame-shaped mouth frame member 2 supported above the bottom plate 1. A side peripheral wall 3 installed between the bottom plate 1 and the mouth frame member 2 is provided so as to surround the storage space S1 formed above the bottom plate 1 over the entire circumference.

The mouth frame member 2 has two pairs of vertical grooves 21 provided so as to open inward and upward at positions facing each other on the inner peripheral surface thereof, and projects upward from a position above each vertical groove 21. It includes a protrusion 23 having a pair of guide surfaces 235 facing each other. In the present embodiment, two pairs of vertical grooves 21 are provided and two partition plates 9 can be inserted, but at least one pair of vertical grooves 21 may be provided.

In the transport container of the present embodiment, the convex end portion 93 of the partition plate 9 that partitions the storage space S1 is guided by the pair of guide surfaces 235 and inserted into the lower vertical groove 21.

Therefore, according to the transport container of the present embodiment, even if the side peripheral wall 3 is deformed so as to bulge outward, the mouth frame member 2 is hard to be deformed, so that the convex end portion of the partition plate 9 is formed. It is possible to prevent the 93 from coming off the flute 21.

Further, since it is not necessary to provide a vertical groove for holding the partition plate 9 on the inner surface of the side peripheral wall 3, there is an advantage that stored items are not caught in the vertical groove and dust does not collect in the vertical groove. is there.

Here, if a vertical groove is formed by denting a part of the inner surface of the side peripheral wall 3, the strength of the side peripheral wall 3 is reduced by that amount. When a vertical groove is formed between the two vertical ribs by projecting a pair of vertical ribs from the inner surface of the side peripheral wall 3, the effective inner dimension of the storage space S1 is reduced by that amount, and the vertical ribs are stored. May get caught. According to the transport container of the present embodiment, the inner surface of the side peripheral wall 3 does not have to be provided with a vertical groove for holding the partition plate 9, so that the strength of the side peripheral wall 3 is reduced and the storage is stored. It does not cause a decrease in the effective inner dimension of the space S1. As described above, it is possible to form a vertical groove communicating with the vertical groove 21 on the side peripheral wall 3.

In addition, according to the transport container of the present embodiment, a pair of guide surfaces 235 are provided above the vertical groove 21, so that when the partition plate 9 is inserted, the partition plate 9 is convex. The work is simple as the end portion 93 may be inserted along the guide surface 235.

In the transport container of the present embodiment, the pair of guide surfaces 235 are provided not on the mouth frame member 2 itself but on the protrusions 23 protruding upward from the mouth frame member 2. Therefore, it is only necessary to provide the mouth frame member 2 with the vertical groove 21 to which the convex end portion 93 is locked, and the vertical dimension of the vertical groove 21 (that is, a partition) within the limited range of the mouth frame member 2. It becomes easy to secure a hooking allowance) capable of sandwiching the convex end portion 93 of the plate 9.

Therefore, when the transport container of the present embodiment is moved by a line such as a roller controller with the lid 4 opened, and the contents are packed, vibration in the vertical direction is generated during the work. In addition, as described above, since the hooking allowance of the convex end portion 93 is secured for a long time within the limited range of the mouth frame member 2, there is an advantage that the partition plate 9 can be suppressed from coming off due to vibration.

The support shaft portion 41 of the lid plate 4 has a pair of guide surfaces 43 facing each other at a distance in the second direction D2 at a position above each vertical groove 21.

A space S2 is formed between the pair of guide surfaces 43. The space S2 is configured to open at least inward, downward, and upward in the first direction D1 when the lid plate 4 is in the fully open state. The convex end portion 93 of the partition plate 9 can pass up and down through the space S2.

When the lid plate 4 is in the fully open state, the pair of guide surfaces 43 are positioned so as to face diagonally upward so that the distance between them increases as the distance from the vertical groove 21 increases.

In the present embodiment, the entire pair of guide surfaces 43 are inclined surfaces, but at least the upper portions of the pair of guide surfaces 43 may be configured so as to be separated from each other toward the upper side.

The minimum width between the pair of guide surfaces 43, 43 is provided to be about the same as the width of the vertical groove 21 in the second direction D2, but in order to smoothly guide the convex end portion 93 to the vertical groove 21, it is vertical. It is also preferable that the groove 21 is provided narrower than the width of the second direction D2.

As shown in FIG. 11, the space S2 between the pair of guide surfaces 43 is formed so as to overlap a part of the vertical groove 21 (the outer half of the vertical groove 21 in the first direction D1) in a plan view. .. It is also possible that the space S2 between the pair of guide surfaces 43 is formed so as to overlap all of the vertical grooves 21 in a plan view.

As shown in FIG. 12, when the lid plate 4 is in the fully open state, a predetermined gap is formed above and below between the support shaft portion 41 of the lid plate 4 and the long side portion 29 of the mouth frame member 2. .. Similarly, a predetermined gap is formed above and below between the space S2 formed between the pair of guide surfaces 43 of the support shaft portion 41 and the vertical groove 21 located below the space S2.

Further, as shown in FIG. 9, a pair of regulation ribs 45 are provided at two locations separated from each other in the second direction D2 on the back surface of the lid plate 4.

The pair of regulating ribs 45 at each location are located so as to sandwich the upper end portion of the partition plate 9 from both sides of the second direction D2 in the fully closed state, and the regulating ribs 45 on both sides move to the second direction D2 of the partition plate 9. Deformation is regulated.

It is configured to be guided by the pair of guide surfaces 43 and inserted into the lower vertical groove 21.

Therefore, according to the transport container of the present embodiment, even if the side peripheral wall 3 is deformed so as to bulge outward, the mouth frame member 2 is not easily deformed, so that the convex end portion of the partition plate 9 is formed. It is possible to prevent the 93 from coming off the flute 21. Further, since it is not necessary to provide a vertical groove for holding the partition plate 9 on the inner surface of the side peripheral wall 3, stored items may be caught in the vertical groove, dust may be accumulated in the vertical groove, and the vertical groove may be formed. There is also an advantage that the strength of the side peripheral wall 3 does not decrease by the amount formed and the effective inner dimension of the storage space S1 does not decrease. Also in this embodiment, it is possible to form a vertical groove communicating with the vertical groove 21 on the side peripheral wall 3.

In addition, according to the transport container of the present embodiment, when the lid plate 4 is fully opened, a pair of guide surfaces 43 are provided above the vertical groove 21, so that the partition plate 9 is inserted.

In the transport container of the present embodiment, the pair of guide surfaces 43 are provided not on the mouth frame member 2 but on the support shaft portion 41 of the lid plate 4. Therefore, the mouth frame member 2 only needs to be provided with the vertical groove 21 to which the convex end portion 93 is locked, and the vertical dimension of the vertical groove 21 (that is, a partition) within the limited range of the mouth frame member 2. A hooking allowance for sandwiching the convex end portion 93 of the plate 9) can be easily secured.

(Modification example)
Although the embodiments have been described above, the transport container is not limited to the above-described embodiments.

For example, FIG. 15 shows a modified example of the bottom plate 1 that can be used in the transport container of the first embodiment and the second embodiment.

Each lateral groove 12 included in the bottom plate 1 has an extension portion 129 extending outward from the end portions 125 on both sides of the first direction D1 shown in the first and second embodiments D1. The tip portion of each extension portion 129 in the first direction D1 is formed wider than the other portions. A drain hole 13 is also formed in each extension portion 129.

Since the lateral groove 12 has the extension portion 129, it is advantageous when the partition plate 9 is made of corrugated cardboard and is used repeatedly.

That is, if the locking portion 95 of the partition plate 9 made of corrugated cardboard is crushed by repeated use, the entire partition plate 9 should be inserted into the portion extending to the extension portions 129 on both sides of the lateral groove 12. Just do it. At this time, even if the corner portion of the partition plate 9 made of corrugated cardboard is turned up to some extent, the tip portion of the extension portion 129 corresponding to both corner portions of the partition plate 9 is formed wide, so that it is easy to insert. Is secured.

Further, the convex end portion 93 of the partition plate 9 is configured to fit over the entire area of the vertical groove 21, but the convex end portion 93 is configured to fit only a part of the vertical dimension of the vertical groove 21. It is possible.

Further, among the annular ribs formed on the back surface of the lid plate 4, a notch can be provided in a portion that vertically overlaps with the partition plate 9 in the fully closed state. In this case, even if the partition plate 9 (convex end portions 93 on both sides) is provided higher by the amount of the notch, it does not interfere with the lid plate 4, so that the hooking allowance between the convex end portion 93 and the vertical groove 21 can be easily secured. Become. Further, it is also possible to regulate the deformation of the partition plate 9 by the end portion of the notch of the annular rib provided in this way.

It is also possible to form the depth of the vertical groove 21 deeper than the protruding length of the convex end portion 93 of the partition plate 9. In this case, since a clearance is provided between the tip of the convex end portion 93 and the vertical groove 21, the work of inserting the partition plate 9 becomes easy. The movement of the inserted partition plate 9 in the first direction D1 is restricted by the both ends of the partition plate 9 hitting the inner surfaces of the side peripheral walls 3 (a pair of long side plates 34).

Further, the vertical groove 21 may be provided so as to be narrower toward the bottom of the groove, or may be provided so as to be narrower toward the lower side. In this case, the convex end portion 93 inserted into the vertical groove 21 is likely to be firmly sandwiched, and the holding force of the partition plate 9 is enhanced.

As for other configurations, it is possible to appropriately change the design of the transport container of each embodiment, or to apply the configurations of each embodiment in appropriate combinations.
