Description

  The present invention relates to a container used when transporting a battery such as a lithium ion battery. In particular, the present invention relates to a battery transport container having advantages such as easy storage and removal of batteries, sufficient strength, and easy stacking and nesting.

  Lithium ion batteries are mounted on, for example, electric vehicles and hybrid vehicles. The shape is generally plate-like and the weight is about several kg. Since this lithium ion battery is designated as a hazardous material during shipping, it is necessary to transport the lithium ion battery so that the liquid inside does not leak even when subjected to an impact. Further, since there is a space inside, the center of gravity is not constant. There is currently no plastic container suitable for storing and transporting lithium ion batteries having such characteristics.

  This invention is made | formed in view of said point, Comprising: It aims at providing a container suitable for flat battery transport, such as a lithium ion battery. In particular, it is an object of the present invention to provide a battery transporting container having advantages such as easy storage and removal of batteries, sufficient strength, and easy stacking and nesting.

  The battery transport container according to the first aspect of the present invention includes a plastic main body having a recess for accommodating a part (lower part) of a plate-like battery, and the battery disposed in the recess of the main body. A body cushioning material formed with a groove into which the lower end is inserted, a recess for accommodating the remaining portion (upper part) of the battery, and a plastic lid for closing the recess of the body; A lid cushioning material disposed in a recess and having a groove into which the upper end of the battery is inserted.

  Here, the lower end portion of the battery means the region including the lower end and the side end thereof in the container accommodation posture of the battery, and the upper end portion is the region including the upper end and the side end thereof in the container accommodation posture of the battery. It means that.

  When the battery is accommodated in the main body, first, the lower part of the battery is put into the recess of the main body, and at that time, the lower end of the battery is inserted into the groove of the buffer material. In this state, the upper part of the battery protrudes outside from the recess of the main body. Next, when the lid is closed, the upper end portion of the battery is inserted into the buffer material groove in the lid. As a result, the battery is positioned / held in the state in which the shock can be absorbed by the buffer material at the top, bottom, left, and right and front and back.

  On the other hand, when taking out the battery from the main body, first, the lid is opened, and at the same time, the upper end of the battery comes out from the groove of the buffer material. In this state, the lower end portion of the battery is accommodated in the buffer groove of the main body, and the upper portion protrudes from the main body recess, so that it is easy to grasp the upper portion of the battery when taking out the battery.

  In the present invention, if the main body and the lid have the same shape, the main body and the lid can be manufactured with the same molding die, and the manufacturing cost can be reduced.

  In the present invention, it is preferable that an uneven fitting portion for stacking with another main body and the lid is formed on the bottom surface of the main body and the upper surface of the lid, and the shape of the same portion is 180 ° rotationally symmetric.

  In this case, stacking is possible even when the main body and the lid are rotated by 180 ° relative to each other. For this reason, when stacking, it is not necessary to pay attention to align the upper and lower containers. Specifically, since the container is generally a rectangular parallelepiped, stacking can be performed simply by aligning the positions of the long side and the short side of the upper and lower containers.

  In the present invention, the recess of the main body and the lid has an outward opening shape, and the cushioning material is disposed only at a portion below the predetermined height of the bottom or ceiling of the main body or the recess of the lid, It is preferred that the empty body and lid can be stacked so as to overlap in their recesses.

  In this case, nesting is possible even though the container has a built-in cushioning material. As a result, the volume when the container is empty can be reduced, the warehouse capacity can be reduced, and the transportation cost can be reduced.

  In the present invention, the side wall of the recess of the main body and / or the lid has a double-wall inner rib structure having a double wall and a rib formed so as to span between both walls. If so, it is possible to prevent chipping of the ribs when dropped, and to prevent destruction of the container.

  In the present invention, a buckle portion for locking the closed lid to the main body is provided at the center of the side wall of the recess of the main body and / or the lid, and the double side is provided on both sides of the buckle portion. An in-wall rib structure is preferably provided.

  According to the present invention, when the container falls, it is easy to directly apply an impact to the rib structure in the double wall at the corner, and it is difficult to apply to the buckle. For this reason, it is possible to avoid a situation in which the buckle portion is damaged by impact or the lock is inadvertently released.

  In this invention, it is preferable that the said double-wall inner rib structure is provided in the height range below about 1/2 below or above from the opening part of the said recessed part of the said main body and a lid | cover.

  Since the opening of the recess of the container is the part that needs the most reinforcement, it is preferable to provide a double-walled rib structure in the opening. And if this double-walled rib structure is about ½ or less of the depth of the recess, there will be no obstacle during nesting.

  A battery transport container according to a second aspect of the present invention comprises a plastic main body having a recess for receiving a plate-like battery, and a plastic lid for closing the recess of the main body, An uneven fitting portion for stacking with another main body and the lid is formed on the bottom surface and the upper surface of the lid, and an end of the fitting portion is an inclined surface, and the bottom surface of the main body is placed on the upper surface of the lid. When placed, the slopes of the fitting parts come into contact with each other, and the fitting part is concavo-convexly fitted by sliding the main body along the slopes with respect to the lid.

  According to the present invention, when stacking containers, the lid and the main body are automatically fitted in the concave and convex portions, so that it is not necessary to accurately align the upper and lower containers.

  A battery transport container according to a third aspect of the present invention includes a plastic main body having a recess for receiving a plate-shaped battery, a plastic lid for closing the recess of the main body, and the closed lid on the main body. A buckle that has a rotation fulcrum part and a hook part, a bearing part that receives the buckle rotation fulcrum, and a buckle lock part that engages the hook part of the buckle. Both the main body and the lid have both.

  According to the present invention, the user can select whether to attach the buckle to either the main body or the lid.

  In the present invention, it is preferable that a finger enters between the buckle and the main body or the lid when the buckle is locked, because a force is easily applied when the buckle is locked.

  In the present invention, if the buckle lock portion has a structure that sandwiches the hook portion of the buckle from above and below, the buckle lock portion can be firmly locked, and the lid and the main body are difficult to open when the container is dropped.

  As apparent from the above description, according to the present invention, it is possible to provide a battery transport container that can easily accommodate and take out the battery. With the container of the present invention, safe and rapid logistics of lithium ion batteries can be actively performed. Further, by providing a structure that reinforces the corners of the container and an uneven fitting portion that can be stacked so as not to be displaced, there are advantages such as sufficient strength and stable stacking.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the container 1 has a main body 10A and a lid 10B, and a main body cushioning material 90A disposed in the main body 10A and a lid cushioning material 90B disposed in the lid 10B. The main body 10A and the lid 10B have the same shape / structure, and the main body cushioning material 90A and the lid cushioning material 90B have the same shape / structure. The main body 10A and the lid 10B are made of plastic (for example, polypropylene), and the main body cushioning material 90A and the lid cushioning material 90B are made of a foamed resin (for example, foamed urethane).
In the following description, the structure of the main body and the lid is denoted by reference numeral 10, and when the main body and the lid are separately represented in terms of function, the main body is denoted by 10A and the lid is denoted by 10B.
In this example, as shown in FIG. 1B, an example will be described in which three plate-like batteries C are housed side by side in a state where the longitudinal side faces are upright. In this case, the container 1 has a rectangular parallelepiped shape.

First, the overall structure of the main body 10 will be described with reference mainly to FIG.
The main body 10 has a rectangular bottom 12 that forms the recess 11, and a side wall 13 that rises from the periphery of the bottom 12. The depth of the recess 11 (height of the main body 10) is approximately the height of the lower half of the battery C (half of the length in the short side direction of the battery C) with the longitudinal side face down. The side wall part 13 has a long side wall 13L that rises slightly diagonally outward from each long side of the bottom part 12, and a short side wall 13S that rises slightly diagonally outward from each short side.

Next, the cushioning material 90 will be described with reference to FIGS. 1, 2, and 3.
The cushioning material 90 has a rectangular parallelepiped shape as a whole, is laid on the bottom of the recess 11 of the main body 10 and is held by the main body 10 by friction. As shown in FIG. 1B, the height of the cushioning material 90 is half of the height of the main body 10 or less. Three rows of grooves 91 are formed on the upper surface of the cushioning material 90. The shape of the groove 91 is the same shape as the longitudinal section of the battery C, the length is the same as the longitudinal length of the battery C, and the width is the same as the thickness of the battery C. Further, the depth of the groove 91 is a dimension that allows the battery C to be held substantially upright, and in this example, is approximately ¼ to の of the short direction length of the battery C. Between the groove 91 and the groove 91, an interval of a predetermined dimension (a degree that a human finger can enter) is provided. In addition, between the grooves 91 on both sides and the side edges of the cushioning material 90, and between both ends of each groove 91 and the side wall portions of the cushioning material 90, a predetermined dimension (a degree that allows human fingers to enter) is also obtained. There is a gap.

The operation of putting the battery C in and out of the container 1 will be described.
When the battery C is accommodated in the main body 10B, first, the lower portion of the battery C is put into the recess 11 of the main body 10A, and the lower end portion of the battery C is inserted into the groove 91 of the cushioning material 90A. In this state, the upper part of the battery C protrudes outside from the recess 11 of the main body 10A. Next, when the lid 10B is closed, the upper end portion of the battery C is inserted into the groove 91 of the cushioning material 90B in the lid 10B. In this state, as shown in FIG. 1 (B), the lower half of the battery C standing with its longitudinal side face down is accommodated in the main body 10A, the lower part is inserted into the cushioning material 90A, and the upper half is the lid 10B. The upper part is inserted into the cushioning material 90B. As a result, the top, bottom, left, and right of the battery C are positioned and held in a state where shock can be absorbed by the cushioning materials 90A and 90B.

  On the other hand, when the battery C is taken out from the main body 10A, first, the lid 10B is opened, and at the same time, the upper end portion of the battery C comes out of the groove 91 of the buffer material 90B. In this state, the lower end portion of the battery C is accommodated in the groove 91 of the cushioning material 90A of the main body 10A, and the upper portion of the battery C projects from the recess 11 of the main body 10A. Then, the upper part of the battery C protruding from the recess 11 is grasped and taken out.

The structure of the back surface of the bottom portion 12 of the main body 10 will be described with reference to FIGS.
On the back surface of the bottom portion 12, a stacking uneven fitting portion is formed which is positioned with respect to the upper surface of the lower container when the container is stacked. The stacking concave / convex fitting portion includes a pair of outer convex portions 20 and a pair of inner convex portions 30 that are arranged in 180 ° rotational symmetry with respect to the center of the bottom portion 12. The outer convex portion 20 is disposed at one diagonal corner of the bottom portion 12, and the inner convex portion 30 is disposed at the other diagonal corner portion of the bottom portion. The cross-sectional shape of each convex part 20 and 40 is the same square, and has a flat upper surface of a predetermined height.

The outer convex portion 20 is formed in an L shape, and has a long side portion 21 </ b> L extending along the long side of the bottom portion 12 and a short side portion 21 </ b> S extending along the short side. The long side portion 21L extends from the corner of the bottom portion 12 to a position that is about half the length of the long side. The short side portion 21S extends from the corner of the bottom portion 12 to a position that is about half the length of the short side. The front ends of the long side portions 21L and the short side portions 21S are inclined surfaces 22L and 22S that are inclined downward (toward the back surface of the bottom portion 12).
The inner convex portion 30 is also formed in an L shape and is formed around the inner side of the outer convex portion 20. The inner convex part 30 also has a long side part 31L extending along the long side of the bottom part 12 and a short side part 31S extending along the short side. The long side portion 31L extends from the corner of the bottom portion 12 to a position that is about half the length of the long side. The short side portion 31 </ b> S extends from the corner of the bottom portion 12 to a position that is about half the length of the short side. The front ends of the long side portions 31L and the short side portions 31S are inclined surfaces 32L and 32S that are inclined downward (toward the back surface of the bottom portion 12).

  As shown in these drawings, the inclined surface 22L of the long side portion 21L of the outer convex portion 20 and the inclined surface 32L of the long side portion 31L of the inner convex portion 30 overlap in the short direction of the bottom portion 12, and the outer convex portion The inclined surface 22S of the short side portion 21S of the portion 20 and the inclined surface 32S of the short side portion 31S of the inner convex portion 30 overlap in the longitudinal direction of the bottom portion 12.

  Further, L-shaped corner ribs 35 are formed at diagonal corners of the bottom surface of the bottom portion 12. The height of the corner rib 35 is the same as the height of the outer convex portion 20 and the inner convex portion 30 of the concave-convex fitting portion. The corner rib 35 is formed on the outer side by the width of the outer convex portion 20 from the inner convex portion 30. The corner rib 35 is for preventing the deformation of the bottom portion 12.

With reference to FIG. 5, the fitting state of the uneven | corrugated fitting part at the time of container stacking is demonstrated.
At the time of stacking, as shown in FIG. 5, the inner convex part 30 of the lid 10B of the lower container 1 is fitted inside the outer convex part 20 of the main body 10A of the upper container 1, and the lower container 1 The outer convex portion 20 of the lid 10B is fitted to the outside of the inner convex portion 30 of the main body 10A of the upper container 1. The inclined surfaces 22 at the tips of the outer convex portions 20 of the main body 10A and the lid 10B are in contact with each other, and the inclined surfaces 32 at the tips of the inner convex portions 30 are in contact with each other. In other words, the inner convex portion 30 of the main body 10B and the inner convex portion 30 of the lid 10A are formed inside the outer frame portion formed by the outer convex portion 20 of the main body 10A and the outer convex portion 20 of the lid 10B. It can be said that the inner frame-like portion is fitted. By this fitting, the upper and lower containers 1 can be accurately positioned and stacked so as not to wobble in the lateral direction.
The outer convex portions 30 of the main body 10A and the lid 10B are fitted into spaces (groove portions) between the inner convex portions 30 of the lid 10B and the main body 10A and the corner ribs 35.

  When stacking the container 1, the upper surface of the lid 10B of the lower container 1 and the lower surface of the main body 10A of the upper container 1 are slid and roughly aligned. When the inclined surfaces 22 and 32 of the convex portions 20 and 30 of the lid 10B reach the inclined surfaces 22 and 32 of the convex portions 20 and 30 of the main body 10A, the lid 10B follows the inclined surface with respect to the main body 10A. And slide. Thereby, both fit automatically.

  Furthermore, since the outer convex portion 20 and the inner convex portion 30 are disposed 180 ° rotationally symmetrically with respect to the center of the bottom portion 12, stacking can be performed even when the main body 10A and the lid 10B are rotated 180 ° relatively. Specifically, since the container 1 has a rectangular parallelepiped shape as described above, stacking can be performed only by aligning the positions of the long side and the short side of the upper and lower containers. In other words, since it is not necessary to match the long sides of the defined side and the short sides of the defined side, it is not necessary to pay attention to align the orientation of the upper and lower containers when stacking.

  Four corners of the outer surface of the side wall 13 of the main body 10 have double-wall inner rib structures 40. As shown in FIG. 2, the structure 40 includes an outer wall 41 that is approximately half the height of the main body 10, an upper wall 42 between the upper end of the outer wall 41 and the upper end of the side wall 13, and the outer wall 41 and the side wall. 13, and a rib 43 formed so as to hang over. By having such a double-wall inner rib structure 40, the strength of the corners of the container 1 can be increased, and chipping when dropped can be prevented.

As shown in FIG. 1A, a lock mechanism 50 that locks the lid 10B and the main body 10A is provided between the double-wall inner rib structures 40 at the corners. As shown in FIG. 2, the lock mechanism 50 includes a buckle 60, a bearing portion 70 formed on the main body 10 to which the buckle 60 is attached, and a buckle lock portion 80 with which the buckle 60 engages.
The lock mechanism 50 may be formed on all the side walls 13L and 13S, or may be formed only on the opposed long side walls 13L or only on the opposed short side walls 13S. However, it is preferable to form it on all the side walls because the locking between the lid 10B and the main body 10A becomes stronger and the lid 10B and the main body 10A are less likely to come off due to an impact at the time of dropping.

  The buckle 60 is separate from the main body 10A or the lid 10B, and as shown in FIG. 2, has a pivot fulcrum 61 at both ends and a hook 62 between them. The rotation fulcrum portion 61 is attached to one bearing portion 70 of the lid or the main body, and the hook portion 62 is locked to the other buckle lock portion 80 of the lid or the main body.

  The main body 10 is formed with a bearing portion 70 that supports the rotation fulcrum portion 61 of the buckle 60 and a buckle lock portion 80 to which the hook portion 62 is locked. The bearing portion 70 is formed at a corner between the upper wall 42 and the endmost rib 43 of both of the opposing double-wall inner rib structures 40, and includes a notch 71 opened in the upper wall 42, a rib And a groove 72 that extends downward from the notch 71. The buckle 60 is inserted into the notch 71 in the upper wall 42 while being slid into the groove 72 of the rib 43 while the pivoting fulcrum 61 of the buckle 60 is deformed inward, and then the buckle 60 is released from the deformation by releasing the deformation of the buckle 60. It is attached to the bearing part 70 so that rotation is possible.

  The buckle lock portion 80 is formed between the bearing portions 70 facing each other, and has a protruding portion 81 protruding outward from the upper end of the side wall 13 and a protruding piece protruding outward from the side wall below the protruding portion 81. 82. The height of the overhanging portion 81 and the protruding piece 82 is shorter than the height of the rib 43 of the double wall structure 40. At two places on the lower surface of the overhang 81, there are formed recesses 83 with which the hooks 62 of the buckle 60 engage. A predetermined gap is opened between the recess 83 and the side wall 13. The distance between the recess 83 and the upper surface of the projecting piece 82 is substantially equal to the width of the hook 62 of the buckle 60.

The rotating action of the buckle 60 will be described with reference to FIG. In this example, a buckle 60 is attached to the main body 10A.
In the unlocked state, as shown in FIG. 6A, the buckle 60 is held by the bearing portion 70 of the main body 10 </ b> A, and the hook portion 62 is positioned below the protruding piece 82. At the time of locking, the buckle 60 is rotated around the bearing portion 70, and the hook portion 62 is engaged with the concave portion 83 of the overhang portion 81 of the buckle lock portion 80 of the lid 10 as shown in FIG. Let The hook 62 is held between the overhang 81 and the projecting piece 82.
At the time of unlocking, the hook 62 of the buckle 60 is removed from the recess 83 of the overhang 81 and rotated around the rotation fulcrum 61. At this time, since a gap is opened between the recess 83 and the side wall 13, it is easy to put a finger.

  In addition, since the bearing part 70 and the buckle lock | rock part 80 are formed in the one main body 10, the main body 10 can respond | correspond to both the side to which the buckle 60 is attached, and the side to which the buckle 60 is locked. In the example shown in FIG. 1, the side to which the buckle 60 is attached is used as the main body 10A, and the side to which the buckle 60 is locked is used as the lid 10B. Note that the lid and the main body can be identified at a glance by changing the colors of the lid 10B and the main body 10A or drawing different patterns.

Next, the stacking state of containers and the nesting state of empty boxes will be described with reference to FIG.
As shown in FIG. 7A, at the time of container stacking, the upper and lower containers 1 are accurately positioned and stacked by the concave / convex fitting of the concave / convex fitting portions 20 and 30 formed on the bottom portion 12.
As shown in FIG. 7 (B), in the case of an empty box, each side wall 13 is inclined slightly obliquely outward with respect to the bottom 12, so that the main body 10 can be stacked in a nested manner. Since the double-wall inner rib structure 40 has a height that is half the height of the main body 10, the lower surface of the double-wall inner rib structure 40 of the upper main body 10 is the double wall of the lower main body 10. It rides on the upper surface of the inner rib structure 40. That is, the lower half of the height of the upper main body 10 enters the lower main body 10. Thereby, the volume at the time of stacking can be reduced.
Further, in this case, since the height of the cushioning material 90 is about half of the height of the main body 10, the bottom 12 of the upper main body 10 does not hit the cushioning material 90 laid on the lower main body 10 during stacking. . That is, the body 10 can be stacked with the cushioning material 90 laid.

As described above, the container of the present invention has the following advantages.
(1) Since the main body 10A and the lid 10B and the main body cushioning material 90A and the lid cushioning material 90B have the same shape and structure, they can be manufactured using the same mold, and the manufacturing cost can be reduced.
(2) When the lid 10B is opened, as shown in FIG. 2, since the upper half of the battery C comes out of the recess 11 of the main body 10A, it is easy to grasp by hand when taking it out.
(3) Since the concave and convex fitting portions 20 and 30 in which the main body and the lid of the upper and lower containers are concave and convex are formed during container stacking, stacking stability can be obtained. Furthermore, since the concave / convex fitting portions 20 and 30 are arranged 180 ° rotationally symmetrically with respect to the center of the bottom, the concave / convex fitting can be performed even if the container is rotated 180 °, and the orientation of the container is conscious when stacked. There is no need to match.
(4) Since the four corners of the container 1 have the double-wall inner rib structure 40, impact resistance at the time of dropping can be obtained.
(5) When a mechanism for locking the lid 10B and the main body 10A with the buckle 60 is provided, both the bearing portion 70 to which the buckle 60 is attached to the lid 10B and the main body 10A and the buckle lock portion 80 to which the buckle 60 is engaged are formed. Therefore, the lid 10B and the main body 10A can be used on either the side where the buckle 60 is attached or the side where the buckle 60 is engaged.
(6) When the locking mechanism 50 between the lid and the main body is provided on all sides, the lid and the main body are difficult to open when dropped.
(7) When transporting the empty box, the lid 10B and the main body 10A can be stacked in a nested manner, and the volume can be reduced.
