Summary of the Invention

Problems to be Solved by the Invention

[0004] In the blank sheet of the above-described conventional tray, two partition plates are continuously provided via a cutting guide line. Then, the partition plates are separated from the blank sheet and placed on the bottom plate in a state where the two partition bodies intersect. In this configuration, there are problems that the assembly work of the partition plates is complicated and the partition plates move on the bottom plate.

[0005] An object of the present invention is to solve the above-described problems and provide a tray capable of easily forming a partition portion on a bottom plate and fixing the partition portion on the bottom plate.

Means for Solving the Problems

[0006] To solve the above problems, the present invention provides a tray comprising a bottom plate, a peripheral wall portion erected at an edge of the bottom plate, and a partition portion erected on the bottom plate. The partition portion has a first partition plate extending in the left-right direction and a second partition plate extending across the first partition plate in the front-rear direction. The lower edge portion of the first partition plate and the lower edge portion of the second partition plate are connected to the bottom plate via a broken line. The first partition plate and the second partition plate are portions erected from within an opening formed in the bottom plate.

[0007] In the tray of the present invention, by bending the first partition plate and the second partition plate with respect to the bottom plate, a partition portion where the two partition plates intersect can be easily erected on the bottom plate. In the tray of the present invention, since the two partition plates are continuous with the bottom plate, the partition portion can be fixed on the bottom plate. In the tray of the present invention, since the partition plate is a portion erected from within the opening of the bottom plate, the blank sheet can be made smaller and the amount of paper used can be reduced.

[0008] In the above-described tray, it is preferable that the maximum height of the second partition plate is formed to be the same height as the upper edge portion of the peripheral wall portion. In this configuration, when the bottom plate of another tray is stacked on the upper edge portion of the peripheral wall portion of the tray and two trays are stacked, the second partition plate of the lower tray abuts against the lower surface of the bottom plate of the upper tray. As a result, since the bottom plate of the upper tray is supported by the second partition plate of the lower tray, the deflection of the bottom plate of the upper tray can be reduced.

[0009] In the above-described tray, the second partition plate is a portion erected from within the opening toward one side in the left-right direction, and the second partition plate is formed with front and rear plate portions connected to the bottom plate and a beam portion bridged over both leg portions. In this case, it is preferable to keep the first partition plate and the second partition plate in an erected state by fitting the lower edge portion of the beam portion into an engagement recess formed in the upper edge portion of the first partition plate.

[0010] Furthermore, when the lower edge of the beam portion of the second partition plate is fitted into the engagement recess formed in the upper edge of the first partition plate, it is preferable that the second partition plate is inclined to one side, either left or right, with respect to the normal line of the upper surface of the bottom plate. In this configuration, when two trays are stacked in the same direction, on the lower surface of the bottom plate of the upper tray, the upper edge of the second partition plate of the lower tray abuts against the side of the region opened by the second partition plate being raised. Therefore, the bottom plate of the upper tray can be reliably supported by the second partition plate of the lower tray.

Effects of the Invention

[0011] In the tray of the present invention, by bending the two partition plates with respect to the bottom plate, the partition portion can be easily erected and fixed on the bottom plate. Further, in the tray of the present invention, since the partition plate is a portion raised from within the bottom plate, the blank sheet can be made smaller and the amount of paper used can be reduced.

Modes for Carrying Out the Invention

[0013] Embodiments of the present invention will be described in detail with appropriate reference to the drawings. In the following description, the front-rear, left-right directions are set for convenience in explaining the tray of the present embodiment, and do not limit the configuration and usage state of the tray.

[0014] As shown in FIG. 1, the tray 1 of this embodiment includes a bottom plate 10 and a peripheral wall portion 20 raised at the edge of the bottom plate 10. The peripheral wall portion 20 includes front and rear end walls 30, 30 and left and right side walls 40, 40 raised at the edge of the bottom plate 10, and an inner wall 41 continuously provided at the upper edge portion of the side wall 40 and folded back to the inner surface side of the side wall 40.

[0015] As shown in FIG. 2, the tray 1 is formed by mountain-folding or valley-folding a blank sheet S cut out from a cardboard sheet at each fold line. The blank sheet S shown in FIG. 2 is arranged so that the inner surface side is visible. The fold lines of the blank sheet S are ruled lines (pressed ruled lines) formed by linearly pressing the surface of the blank sheet S. Note that intermittent cuts may be formed in the ruled lines. By doing so, it becomes easier to bend the blank sheet S at the ruled lines. Alternatively, the fold lines may be formed by intermittently and linearly forming half-cut cuts that only cut the surface of the sheet or cuts that penetrate the sheet.

[0016] As shown in FIG. 1, the left and right side walls 40, 40 are continuously provided at the left and right edge portions of the bottom plate 10 via fold lines, respectively, and extend upward from the left and right edge portions of the bottom plate 10. The side wall 40 is formed perpendicular to the bottom plate 10.

[0017] An inner wall 41 is continuously provided at the upper edge portion of the side wall 40 via two left and right fold lines. The inner wall 41 is folded back to the inner surface side of the side wall 40. The lower edge portion of the inner wall 41 is in contact with the upper surface of the bottom plate 10.

[0018] The front and rear end walls 30, 30 are continuously provided at the front and rear edge portions of the bottom plate 10 via fold lines, respectively, and extend upward from the front and rear edge portions of the bottom plate 10. The front and rear end walls 30, 30 are formed perpendicular to the bottom plate 10.

[0019] On the left and right edges of the end wall 30, left and right inner flaps 31, 31 are continuously provided via fold lines. The inner flap 31 is bent inward with respect to the end wall 30 and is sandwiched between the side wall 40 and the inner wall 41.

[0020] In the tray 1 of the present embodiment, an opening 50 and a partition 60 are formed in the central portion of the bottom plate 10. The opening 50 is formed by a first opening region 51 formed in the right half region of the bottom plate 10 and a second opening region 52 formed in the left half region of the bottom plate 10. The first opening region 51 is recessed from the right edge of the second opening region 52 (see FIG. 2).

[0021] The first opening region 51 is formed in a substantially rectangular shape. The front edge of the first opening region 51 is disposed at the center in the front-rear direction of the bottom plate 10. The second opening region 52 is formed larger in the front-rear direction than the first opening region 51. The second opening region 52 is formed such that the width in the front-rear direction is smaller on the left edge than on the right edge. The right edge of the second opening region 52 is disposed at the center in the left-right direction of the bottom plate 10. A third opening region 53 recessed leftward is formed in the left edge of the second opening region 52. The third opening region 53 is closed by a cover plate 54, and the left edge of the cover plate 54 is continuously provided to the bottom plate 10 via a fold line.

[0022] As shown in FIG. 1, the partition 60 is disposed at the center of the upper surface of the bottom plate 10. The partition 60 is formed by orthogonally intersecting a first partition plate 61 extending in the left-right direction and a second partition plate 62 extending in the front-rear direction.

[0023] The first partition plate 61 is erected perpendicularly to the upper surface of the bottom plate 10. The first partition plate 61 is disposed at the center in the front-rear direction of the bottom plate 10. The lower edge of the right portion 61b (right half portion) of the first partition plate 61 is continuously provided to the front edge of the first opening region 51 via a fold line. The left portion 61a (left half portion) of the first partition plate 61 extends above the second opening region 52.

[0024] In the state of the blank sheet S shown in FIG. 2, the first partition plate 61 is disposed within the opening 50. The right portion 61b of the first partition plate 61 is fitted into the first opening region 51, and the first opening region 51 is closed by the right portion 61b. The left portion 61a of the first partition plate 61 is disposed within the second opening region 52. As shown in FIG. 1, by bending the first partition plate 61 forward with respect to the bottom plate 10, the first partition plate 61 is raised on the upper surface of the bottom plate 10.

[0025] As shown in FIG. 3, an engaging recess 61c is formed in the middle portion of the upper edge of the first partition plate 61. The upper edge of the first partition plate 61 is gently curved in an arc shape as a whole from the left edge of the first partition plate 61 to the engaging recess 61c, and extends linearly from the engaging recess 61c toward the right edge.

[0026] As shown in FIG. 1, the second partition plate 62 is raised at the center in the left - right direction on the upper surface of the bottom plate 10. The second partition plate 62 is formed with front and rear leg portions 62a, 62a continuously provided to the bottom plate 10 on both the front and rear sides of the first partition plate 61, and a beam portion 62b spanned between the both leg portions 62a, 62a. The beam portion 62b extends in the front - rear direction beyond the upper side of the first partition plate 61. The second partition plate 62 is formed in an arch shape curved upward by the front and rear leg portions 62a, 62a and the beam portion 62b. A recessed portion 62c recessed upward is formed in the middle portion of the lower edge of the second partition plate 62.

[0027] In the state of the blank sheet S shown in FIG. 2, the second partition plate 62 is fitted into the second opening region 52 of the opening 50. Further, the left portion 61a of the first partition plate 61 is fitted into the recessed portion 62c of the second partition plate 62. The second opening region 52 is closed by the second partition plate 62 and the left portion 61a of the first partition plate 61. As shown in FIG. 1, by bending the second partition plate 62 rightward with respect to the bottom plate 10, the second partition plate 62 is raised on the upper surface of the bottom plate 10.

[0028] In the partition portion 60 of the present embodiment, as shown in FIG. 3, when the first partition plate 61 and the second partition plate 62 intersect, the lower edge portion (the edge portion of the recessed portion 62c) of the beam portion 62b is configured to contact the upper edge portion of the first partition plate 61. Further, a part of the lower edge portion of the beam portion 62b is fitted into the engaging concave portion 61c of the first partition plate 61. In a state where the lower edge portion of the beam portion 62b is fitted into the engaging concave portion 61c of the first partition plate 61, the second partition plate 62 is held in a state slightly inclined to the right with respect to the normal line L1 of the upper surface of the bottom plate 10. In this state, the upper edge portion of the second partition plate 62 is disposed to the right of the second opening region 52. That is, the angle formed between the second partition plate 62 in the raised state and the second partition plate 62 in a state fitted into the second opening region 52 of the opening 50 is greater than 90 degrees.

[0029] In the present embodiment, as shown in FIG. 1, the maximum height of the second partition plate 62 is set to be the same as the height of the upper edge portion of the peripheral wall portion 20. Specifically, as shown in FIG. 4, the maximum height of the second partition plate 62 is set to be the same as the height of the portion of the upper edge of the peripheral wall portion 20 on which the bottom plate 10 of another tray 1 is placed when another tray 1 is stacked on the tray 1. Therefore, when the trays 1 are stacked, the upper edge portion of the second partition plate 62 of the lower tray 1 abuts against the lower surface of the bottom plate 10 of the upper tray 1.

[0030] As shown in FIG. 2, when raising the first partition plate 61 and the second partition plate 62 from the state where the first partition plate 61 and the second partition plate 62 are fitted into the opening 50, first, the cover plate 54 is pushed in from above to open the third opening region 53. Then, insert a fingertip into the third opening region 53, hook the fingertip on the second partition plate 62, and bend the second partition plate 62 rightward with respect to the bottom plate 10 as shown in FIG. 1. In this way, the second partition plate 62 is raised with respect to the bottom plate 10. Subsequently, insert a finger into the second opening region 52, place a finger on the first partition plate 61, and bend the first partition plate 61 forward with respect to the bottom plate 10. In this way, the first partition plate 61 is raised into the recess 62c of the second partition plate 62.

[0031] Furthermore, as shown in FIG. 3, while arranging the first partition plate 61 perpendicular to the bottom plate 10, adjust the inclination of the first partition plate 61 and the second partition plate 62 such that the lower edge of the beam portion 62b of the second partition plate 62 is fitted into the engagement recess 61c of the first partition plate 61. In this way, the first partition plate 61 and the second partition plate 62 are connected to form a partition portion 60 at the central portion of the bottom plate 10.

[0032] In the tray 1 as described above, as shown in FIG. 1, by bending the first partition plate 61 and the second partition plate 62 with respect to the bottom plate 10, the partition portion 60 where the two partition plates 61 and 62 intersect can be easily erected on the bottom plate 10. In the tray 1 of the present embodiment, since the two partition plates 61 and 62 are continuous with the bottom plate 10 via a fold line, the partition portion 60 can be fixed on the bottom plate 10. In the tray 1 of the present embodiment, by fitting the lower edge of the beam portion 62b of the second partition plate 62 into the engagement recess 61c formed in the upper edge of the first partition plate 61, the first partition plate 61 and the second partition plate 62 can be kept in an erected state.

[0033] In the tray 1 of the present embodiment, the first partition plate 61 and the second partition plate 62 are parts that are raised from within the opening 50 formed in the bottom plate 10 (see FIG. 2). Therefore, compared with the case where partition plates are continuously provided via a cutting guide line at the outer edge of the blank sheet S, the blank sheet S can be made smaller, and the paper usage amount can be reduced.

[0034] In the tray 1 of the present embodiment, as shown in FIG. 3, the maximum height of the second partition plate 62 is formed at the same height as the upper edge portion of the peripheral wall portion 20. Further, the second partition plate 62 is inclined with respect to the normal line L1 of the upper surface of the bottom plate 10, and the upper edge portion of the second partition plate 62 is disposed on the side of the second opening region 52. In this configuration, as shown in FIG. 4, when two trays 1, 1 are stacked in the same direction, the upper edge portion of the second partition plate 62 of the lower tray 1 abuts on the lower surface of the bottom plate 10 of the upper tray 1 at a position on the side of the second opening region 52. Thereby, the bottom plate 10 of the upper tray 1 can be reliably supported by the second partition plate 62 of the lower tray 1, and the deflection of the bottom plate 10 of the upper tray 1 can be reduced.

[0035] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above embodiments, and can be appropriately modified without departing from the spirit thereof. In the tray 1 of the present embodiment, as shown in FIG. 1, one partition portion 60 is disposed at the central portion of the bottom plate 10. However, the position, number, or size of the partition portion 60 is not limited, and can be appropriately set according to the number and shape of the contents. In the tray 1 of the present embodiment, the first partition plate 61 and the second partition plate 62 are orthogonal to each other. However, the first partition plate 61 and the second partition plate 62 may intersect obliquely.

[0036] In the tray 1 of the present embodiment, the partition portion 60 is formed by two partition plates 61, 62. However, the number of the partition plates 61, 62 is not limited. For example, a plurality of second partition plates 62 may be combined with one first partition plate 61, or a plurality of first partition plates 61 may be combined with one second partition plate 62.

[0037] The tray 1 of the present embodiment is made of cardboard, but the tray may be formed of various known paperboards.
