Description

Technical Field

[0001] The present invention mainly relates to a transport container for storing and transporting articles, and particularly to a transport container that can be stacked.

Background Art

[0002] Conventionally, as a stackable transport container that opens upward, there is known a transport container that includes synthetic resin corner members and does not include a synthetic resin frame member that covers the upper edge of the container body between the corner members. The transport container can prevent lateral displacement of the stacked transport containers by the corner members. Further, by not providing a frame member between the corner members, the weight of the transport box can be reduced, assembly becomes easy, and furthermore, there is an advantage that a display portion such as printing can be made as large as possible on the side wall surface within a limited size range.

[0003] As the above-described transport container, there is known a disassemblable transport container (transport or storage case) that is composed of an assembly case using a plastic plate or the like and a plastic simple assembly box corner (corner member), and does not include a frame member between the corner members (see, for example, Patent Document 1).

[0004] Further, there is known a box body made of cardboard, which is assembled with each side wall plate composed of a triple side wall construction plate, has corner members at the corners, and does not include a frame member between the corner members (see, for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0006] The transport container according to Patent Document 1 has a configuration in which the placement surface in the corner member is located above the upper surface of the side wall plate. For this reason, stacking is performed. However, since a part of the bottom surface of the transport or storage case placed above abuts on the placement surface of the corner member, a gap is formed between the bottom surface of the transport or storage case placed above and the upper surface of the side wall plate of the transport or storage case located below. Since foreign matters such as dust easily enter through this gap, it is not suitable for use in transporting storage items (for example, finished products, semi-finished products, etc. such as food and pharmaceuticals) that dislike adhesion of dust and the like as the use of the transport or storage case.

[0007] In addition, the box body made of cardboard according to Patent Document 2 has a configuration that allows stacking. However, similar to Patent Document 1, since a part of the bottom surface of the box body placed above abuts on the placement surface of the corner member, a gap is formed between the bottom surface of the box body placed above and the upper surface of the side wall plate of the box body located below. For this reason, similar to the transport or storage case according to Patent Document 1, foreign matters such as dust easily enter through the gap, and it is not suitable for use in transporting storage items that dislike adhesion of dust and the like.

[0008] The present invention has been made in view of the above circumstances, and an object of the invention is to provide an excellent transport container that can be stacked while preventing the intrusion of dust and the like, is non-disintegrating, and has high strength.

Means for Solving the Problems

[0009] The present invention relates to a container body having a bottom plate and side wall plates erected around the bottom plate and opening upward, and corner members are provided at the upper four corners of the container body. The corner member includes a corner member outer wall that abuts on the outer surface of the side wall plate, a corner member inner wall that abuts on the inner surface of the side wall plate, a placement plate that connects the upper edge of the corner member outer wall and the upper edge of the corner member inner wall, and a regulating plate that is provided perpendicular to the placement plate and prevents the left-right movement of the transport container to be loaded thereon. The corner member outer wall, the corner member inner wall, and the placement plate have a groove portion in an L shape when viewed from the bottom. In a transport container not provided with a frame member between the corner members, the upper surface of the placement plate of the corner member and the upper surfaces of the side wall plates of the container body are on the same horizontal plane, which is used as a means for solving the above problems.

Effect of the Invention

[0010] According to the present invention, since the upper surface of the placement plate of the corner member and the upper surfaces of the side wall plates of the container body are on the same horizontal plane, the transport containers can be stacked in a stepped manner while keeping the upper surfaces of the placement plate and the side wall plates horizontal, and a state where no gap is formed between the upper surfaces of the placement plate and the side wall plates and the bottom surface of the transport container to be loaded can be achieved, and the intrusion of dust and the like can be prevented.

Mode for Carrying Out the Invention

[0012] The present invention includes a container body having a bottom plate and side wall plates erected around the bottom plate and opening upward, and corner members are provided at the upper four corners of the container body. The corner member includes a corner member outer wall that contacts the outer surface of the side wall plate, a corner member inner wall that contacts the inner surface of the side wall plate, a mounting plate that connects the upper edges of the corner member outer wall and the corner member inner wall, and a regulating plate that is provided perpendicular to the mounting plate and prevents the left-right movement of the stacked transport containers. The corner member outer wall, the corner member inner wall, and the mounting plate have a groove portion in an L shape when viewed from the bottom. In a transport container not provided with a frame member between the corner members, the upper surface of the mounting plate of the corner member and the upper surfaces of the side wall plates of the container body are on the same horizontal plane (first configuration).

[0013] According to the above first configuration, since the upper surface of the mounting plate of the corner member and the upper surfaces of the side wall plates of the container body are on the same horizontal plane, the transport containers can be stacked in a stepped manner while keeping the upper surfaces of the mounting plate and the side wall plates horizontal, and a state can be achieved in which no gap is formed between the upper surfaces of the mounting plate and the side wall plates and the bottom surface of the transport container to be mounted, thereby preventing the intrusion of dust and the like.

[0014] Further, in the present invention, on the premise of the above first configuration, the container body can be a transport container in which a step portion is provided on the upper surface of the side wall plate to form a low-height portion at the corner portion, and the height of the step portion is made to coincide with the thickness of the mounting plate of the corner member (second configuration).

[0015] According to the above second configuration, one aspect of the above first configuration can be realized. Since the upper surface of the mounting plate of the corner member and the upper surfaces of the side wall plates of the container body are on the same horizontal plane, the transport containers can be stacked in a stepped manner while keeping the upper surfaces of the mounting plate and the side wall plates horizontal, and a state can be achieved in which no gap is formed between the upper surfaces of the mounting plate and the side wall plates and the bottom surface of the transport container to be mounted, thereby preventing the intrusion of dust and the like.

[0016] Further, in the present invention, in the above second configuration, the container body has an engagement hole in the side wall plate, the corner member is provided with an engagement protrusion at least on the outer wall or the inner wall of the corner member, and the distance from the upper surface of the low-height portion to the engagement hole is made to coincide with the distance from the lower surface of the mounting plate of the corner member to the engagement protrusion, so that a transport container can be obtained (third configuration).

[0017] According to the above third configuration, one aspect of the above second configuration can be realized. Since the upper surface of the mounting plate of the corner member and the upper surfaces of the side wall plates of the container body are on the same horizontal plane, the transport containers can be stacked in a stepped manner while keeping the upper surfaces of the mounting plate and the side wall plates horizontal, and a state can be achieved in which no gap is formed between the upper surfaces of the mounting plate and the side wall plates and the bottom surface of the transport container to be mounted, thereby preventing the intrusion of dust and the like.

[0018] Based on any of the above configurations, each side wall plate of the present invention can be a transport container including a plurality of side wall constituent plates to be polymerized (a fourth configuration).

[0019] According to the fourth configuration, in addition to achieving the effects of any of the above configurations, since each side wall plate is constituted by a plurality of side wall constituent plates to be polymerized, mutual deformation can be prevented by mutual contact, and sufficient strength can be ensured.

[0020] Based on any of the above configurations, each side wall plate of the present invention can be a transport container composed only of a single side wall constituent plate having a thickness of 4 mm or more (a fifth configuration).

[0021] According to the fifth configuration, due to the thickness of 4 mm or more of each side wall plate, deformation can be suppressed, the configuration of the unfolded state (plate-like body) of the container body can be simplified, and the manufacturing cost can be reduced.

[0022] Further, based on any of the above configurations, the corner member can be a transport container including a protruding portion corresponding to the L-shaped corner portion in the L-shaped groove portion, and a concave portion that abuts against the protruding portion at the corner portion of the container body (a sixth configuration).

[0023] According to the fourth configuration, in addition to achieving the effects of any of the above configurations, the protruding portion itself improves the strength of the corner member, and by the protruding portion abutting against the concave portion of the container body, it becomes possible to receive the weight of the transport containers stacked upward.

[0034] In this embodiment, each of the side plates (11A, 12A, 13A, 14A) and each of the reinforcing plates (11B, 12B, 13B, 14B) shown above serve as side wall constituent plates for constituting each side wall plate (11, 12, 13, 14).

[0035] As shown in FIG. 4(a), in order to bend the synthetic resin plate 1A, a heating and pressing means M is used. The heating and pressing means M has a linear pressing portion at the lower part. For the heating and pressing with respect to the fifth and sixth boundary lines L5 and L6, the seventh and eighth boundary lines L7 and L8, the ninth and tenth boundary lines L9 and L10, and the eleventh and twelfth boundary lines L11 and L12, a heating and pressing means M having two parallel linear pressing portions is used so as to perform the processing for the two boundary lines at one time.

[0036] First, as shown in FIG. 4(a), heat pressing is performed on the fifth and sixth boundary lines L5 and L6, and the seventh and eighth boundary lines by the heat pressing means M. Then, the fifth and sixth boundary lines L5 and L6, and the seventh and eighth boundary lines are respectively valley-folded and fixed in that state. As a result, as shown in FIG. 4(b), the front wall 11 and the rear wall 12 are respectively formed. Next, heat pressing is performed on the ninth and tenth boundary lines L9 and L10, and the eleventh and twelfth boundary lines L11 and L12 by the heat pressing means M. Then, the ninth and tenth boundary lines L9 and L10, and the eleventh and twelfth boundary lines L11 and L12 are respectively valley-folded and fixed in that state. As a result, as shown in FIG. 5(a), the left side wall 13 and the right side wall 14 are formed.

[0037] Next, as shown in FIG. 5(a), heat pressing is respectively performed on the third boundary line L3 and the fourth boundary line L4 by the heat pressing means M provided with only one linear pressing portion at the lower part. After heat pressing, the third boundary line L3 and the fourth boundary line L4 are respectively valley-folded and fixed in that state. As a result, as shown in FIG. 5(b), the left side wall 13 and the right side wall 14 can be erected and formed. Further, as shown in the same figure, heat pressing is respectively performed on the first boundary line L1 and the second boundary line L2 by the heat pressing means M. After heat pressing, the semi-molten connecting pieces 110 and 120 are brought into contact with the connecting cutouts 130 and 140 of the left side wall 13 and the right side wall, whereby the portion is fixed, and the container body 1 shown in FIG. 2 is configured.

[0038] As shown in Fig. 6, the corner member 2 includes a corner member outer wall 20 that abuts against the outer surfaces of the side wall plates 11, 12, 13, and 14, a corner member inner wall 21 that abuts against the inner surfaces of the side wall plates 11, 12, 13, and 14, a mounting plate 22 that connects the upper edge of the corner member outer wall 20 and the upper edge of the corner member inner wall 21, and a regulating plate 23 that is provided perpendicular to the mounting plate 22 and prevents the lateral movement of the transport container C placed thereon. The corner member outer wall 20 and the corner member inner wall 21 face each other but are not completely parallel to each other. As shown in Figs. 6(a), (c), etc., the relative distance at the lower end side is shorter than that at the upper end side, and it has a slightly constricted configuration downward. And, the corner member outer wall 20, the corner member inner wall 21, and the mounting plate 22 form a groove portion 25 having an L-shaped cross section when viewed from the bottom. Facing into the L-shaped groove portion 25 when viewed from the bottom, the corner member outer wall 20 and the corner member inner wall 21 each have an engaging protrusion 24 facing each other. Further, a protruding portion 26 is formed at the corner portion of the corner member outer wall 20 facing into the L-shaped groove portion 25 when viewed from the bottom.

[0039] Also, as shown in the enclosed partial cross-section S1 of Figs. 7(a) and 7(b), the height H of the stepped portion 16E of the container body 1 is configured to be equal to the thickness T of the mounting plate 22 of the corner member 2. Further, the distance D1 from the upper surface 16 of the low-profile portion 16D of the container body 1 to the engaging hole 15 is configured to be equal to the distance D2 from the lower surface of the mounting plate 22 of the corner member 2 to the engaging protrusion 24.

[0040] As shown in the enclosed partial cross-section S2 of Figs. 7(c) and 7(d), when the L-shaped groove portion 25 of the corner member 2 when viewed from the bottom is fitted into the low-profile portion 16D of the container body 1 and the protruding portion 26 of the corner member 2 is brought into contact with the recess 17 of the container body 1, the engaging protrusion 24 of the corner member 2 fits into the engaging hole 15 of the container body 1. At the same time, the end portion of the corner member 2 is adjacent to the stepped portion 16E of the container body 1, and the upper surface 22A of the mounting plate 22 of the corner member 2 and the upper surfaces 18 of the side wall plates 11, 12, 13, and 14 of the container body 1 are arranged on the same horizontal plane (that is, so-called flush).

[0041] Since the upper surface 22A of the mounting plate 22 of the corner member 2 and the upper surfaces 18 of the side wall plates 11, 12, 13, 14 of the container body 1 are arranged on the same horizontal plane in the transport container C according to the above embodiment, as shown in FIG. 8, when stacking the second transport container C on the first transport container C, the bottom plate 10 of the second transport container C contacts the upper surface 22A of the mounting plate 22 of the first transport container C and the upper surfaces 18 of the side wall plates 11, 12, 13, 14 of the first transport container C. Therefore, no gap is formed between the first transport container C and the second transport container C, and intrusion of dust or the like can be prevented.

[0042] In addition, in the above embodiment, the container body 1 is configured such that the side wall plates 11, 12, 13, 14 are composed of the side plates 11A, 12A, 13A, 14A, the edge forming plates 180, and the reinforcing plates 11B, 12B, 13B, 14B. However, the present invention is not limited to the above embodiment.

[0043] For example, as another embodiment, as shown in FIG. 9, the side wall plates 11, 12, 13, 14 of the container body 1 may be configured by a single plate. That is, the side wall plates 11, 12, 13, 14 can be composed of only a single side wall configuration plate.

[0044] Here, when the side wall plates 11, 12, 13, 14 are configured by a single plate, the plate thickness is desirably 4 mm or more. By having a thickness of 4 mm or more, deformation of each side wall plate can be suppressed while being composed of a single side wall configuration plate. The container body 1 according to the other embodiment in which the side wall plates 11, 12, 13, 14 are formed by a single plate is shown in FIG. 10, and the transport container C is shown in FIG. 11.

[0045] In addition, in the present invention, there is no limitation on the thickness of the mounting plate 22. For example, it includes forming the mounting plate 22 thick and making its interior hollow.

[0046] In the above embodiment, the engagement hole 15 is a square hole, and the engagement protrusion 24 also has a corresponding shape. However, in the present invention, the shapes of the engagement hole 15 and the engagement protrusion 24 are not limited to those in the embodiment. As shown in other embodiments, the engagement hole 15 can be a round hole or the like, and the engagement protrusion can also have a corresponding shape.

[0047] In the above embodiment, a configuration is disclosed in which the container body 1 is provided with a recess 17 and the corner member 2 is provided with a protruding portion 26 corresponding thereto. However, the present invention does not necessarily have to have such a configuration.

[0048] In the above embodiment, the container body 1 is made of foamed polypropylene. However, the present invention is not limited thereto. For example, it can also be made of foamed polyethylene or the like. Further, not only foamed synthetic resin materials but also non-foamed synthetic resin materials can be used.
