  By the way, when carrying a box-shaped container, the box-shaped container is pulled and slid to the near side, so that it is easier for an operator to hold the box-shaped container (the handle of the box-shaped container becomes easier to grasp Such a relative position) is often followed by lifting the box-shaped container. For example, as shown in FIG. 11, when the box-shaped containers 51 stacked one above the other are sequentially taken out from the car 61 including the fence 62 that surrounds the three side surfaces of the box-shaped container 51, the figure is shown in FIG. 11. The box-type container 51 has handles 53 formed on the front side and the back side without the fence 62, but there is a gap between the back side of the box-type container 51 and the fence 62. In the absence, the hand 53 on the back side cannot be put on, so it is necessary to pull the box-shaped container 51 once to the front side.

  However, as shown in FIG. 11, when the inner width of the cage wheel 61 and the width of the box-shaped container 51 are substantially the same, the box-shaped container 51 is pulled out by placing a hand on the side surface of the box-shaped container 51. In addition, there is no gap for the hand to enter between the both side surfaces of the box-shaped container 51 and the fence 62 of the car 61, and it is impossible to even contact the side surface of the box-shaped container 51. Further, the box-shaped container 51 shown in FIG. 11 includes a lid member 54. When foods that require temperature management are stored, the lid member 54 is opened for cold insulation, thermal insulation, hygiene management, and the like. In other words, the inner surface of the box-shaped container 51 cannot be handled.

  Furthermore, the foamed synthetic resin box-shaped container 51 cannot be provided with irregularities or ribs for the sake of convenience of molding and the necessity of ensuring a predetermined strength.

  The present invention has been made to solve the above-described problems and the like, and its purpose is to improve workability in the case of moving by pulling the front side in a box-shaped container made of a synthetic foam resin.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIGS. 1 to 3 and the like, the box-shaped container 1 includes a substantially square box-shaped container body 2 that opens upward, and a lid member 4 (see FIG. 7) that can close the opening of the container body 2. It has. The container body 2 includes a substantially rectangular plate-shaped bottom wall portion 7, a long side wall portion 8 as a first side wall portion extending upward from a pair of opposed long side portions of the bottom wall portion 7, and a bottom A short side wall portion 9 as a second side wall portion extending upward from a pair of opposing short side portions of the wall portion 7 is provided.

  Moreover, the container main body 2 and the lid member 4 of this embodiment are each configured by being integrally molded with foamed polypropylene. For this reason, compared with what is comprised with a non-foaming material, the thickness is comprised thickly as a whole, and a level | step difference etc. are formed by changing thickness. Furthermore, the box-shaped container 1 of the present embodiment is used for transporting and storing foods that require temperature control, and as shown in FIG. 6, on the inner surface side of one long side wall portion 8. Is formed with an in-wall accommodating portion 11 capable of accommodating a cooling agent, a heat insulating material, and the like.

  As shown in FIG. 7, the outer dimension of the lid member 4 is substantially the same as the outer dimension of the container body 2. Even if the lid member 4 is put on the container body 2, the lid member 4 is larger than the container body 2. It does not protrude outward. Moreover, although illustration is omitted, on the lower surface side of the lid member 4, when the lid member 4 is put on the container body 2, a fitting convex portion that fits on the inner peripheral side of the side wall portions 8 and 9 of the container body 2 is provided. Is provided. Thereby, the position shift in the horizontal direction of the lid member 4 with respect to the container main body 2 is prevented.

  Further, on the upper surface side of the lid member 4, a stacking convex portion 12 that protrudes upward along the outer peripheral edge is provided. On the other hand, as shown in FIG. 3 and the like, the container body 2 is covered with the lid member 4 by forming the outer peripheral edge of the bottom wall portion 7 higher on the lower surface of the bottom wall portion 7 of the container body 2. When the box-shaped containers 1 in the state are stacked up and down (stacked), a receiving portion 13 is formed that is supported by contacting the upper surface of the stacking convex portion 12. For this reason, in the stacked state of the box-shaped containers 1, the portion located on the inner peripheral side of the receiving portion 13 of the bottom wall portion 7 of the upper box-shaped container 1 is used for stacking the lower box-shaped containers 1. It will be fitted to the inner peripheral side of the convex part 12. Thereby, the box-shaped containers 1 can be stacked (stacked) while preventing positional displacement in the horizontal direction. The container main bodies 2 with the lid member 4 removed and the lid members 4 can be stacked together.

  As shown in FIG. 3 to FIG. 5 and the like, in this embodiment, the short side is within the range including the boundary portion with each short side wall 9 on the outer surface side of one long side wall 8. The first concave portion 21 is formed so as to reduce the lateral width of the side wall portion 9, and the container is more adjacent to the central portion side in the lateral width direction of the long side wall portion 8 of the first concave portion 21 than the first concave portion 21. A second recess 22 that is recessed inward is formed. Thereby, in the site | part connected to the 1st recessed part 21 among the inner surfaces of the 2nd recessed part 22, when the box-type container 1 is pulled to the near side from the short side wall part 9 side, the latching surface 24 on which a finger can be hung. Is formed. In addition, there is no partition other than the level | step difference (locking surface 24) by the difference in depth between the 1st recessed part 21 and the 2nd recessed part 22, and the bottom face (surface which faces the container outward) of the 1st recessed part 21 And the locking surface 24 which is the inner surface of the second recess 22 are connected.

  As shown in FIG. 3 etc., the 1st recessed part 21 and the 2nd recessed part 22 of this embodiment are formed below the up-down direction center part of the long side wall part 8. In addition, a portion of the outer surface of the long side wall 8 that is directly above the first recess 21 and the second recess 22 is not recessed, and is flush with other portions (such as a side portion of the second recess 22). It has become. For this reason, the inner surface of the 1st recessed part 21 and the 2nd recessed part 22 which demarcates the upper edge part of the 1st recessed part 21 and the 2nd recessed part 22 will be formed. Hereinafter, the inner surface that defines the upper edge of the first recess 21 and the second recess 22 is referred to as a “support surface 25”. In the present embodiment, the support surface 25 constitutes a support portion.

  The support surface 25 protrudes outward from the container when the bottom surfaces of the first recess 21 and the second recess 22 are used as a reference. For this reason, if the hand inserted in the 1st recessed part 21 and the 2nd recessed part 22 is moved upwards, the upper side part (side surface etc. of an index finger) will contact | abut to the support surface 25. FIG. Further, when the support surface 25 is pushed up from such a contact state, the near side of the box-shaped container 1 is lifted.

  As shown in FIGS. 3, 5, etc., the support surface 25 extends in a substantially orthogonal direction with respect to the bottom surfaces of the first recess 21 and the second recess 22 and the outer surface of the long side wall portion 8. In particular, in the present embodiment, the height positions of the upper edge portions of the first concave portion 21 and the second concave portion 22 are aligned, and the portion corresponding to the first concave portion 21 and the second concave portion 22 of the support surface 25 correspond. The part is flush. For this reason, it is possible to support the support surface 25 with as wide an area as possible, and it is easy to apply a force when the front side of the box-shaped container 1 is floated. The first concave portion 21 and the second concave portion 22 are extended to the lower surface of the bottom wall portion 7, and the first concave portion 21 and the second concave portion 22 that define the lower edge portions of the first concave portion 21 and the second concave portion 22 and There is no inner surface of the second recess 22.

  Further, the horizontal width of the first recess 21 is such that the remaining fingers are inserted into the first recess 21 and the second recess 22 while the thumb is hung on the outer surface of the short side wall 9, and the fingertip is hung on the locking surface 24. The width is such that it can be (for example, 20 mm to 90 mm). Furthermore, the depth from the outer surface of the long side wall portion 8 of the first recess 21 is slightly longer than the thickness of the adult hand. Further, the second recess 22 has a space in which a finger joint inserted through the first recess 21 to the second recess 22 is allowed to bend in the second recess 22.

  Further, as shown in FIG. 4 and the like, in this embodiment, the locking surface 24 formed so as to extend vertically at the boundary between the first recess 21 and the second recess 22 has a long side facing upward. The side wall 8 is inclined toward the center in the width direction. Furthermore, as shown in FIG. 3, FIG. 6, etc., the boundary part formed between the side part of the short side wall part 9 and the 1st recessed part 21 is a round chamfering shape. In addition, the boundary portion between the bottom surface of the first recess 21 and the locking surface 24 is also chamfered, but the area of the flat surface on which the finger is hung is not reduced as much as possible. As described above, the radius of curvature is smaller than that of the side portion of the short side wall portion 9, the first recess 21, and the boundary portion.

  Further, as shown in FIG. 1 and the like, on the outer surface side of each short side wall portion 9, a handle 27 on which a finger is hung when the box-shaped container 1 is lifted at the center in the width direction of the short side wall portion 9. Is formed. The handle 27 is located above the first recess 21 and the second recess 22.

  Moreover, as shown in FIG. 7, the corresponding cage 31 is provided in the box-shaped container 1 of this embodiment. The car 31 is a base plate 32 having a substantially rectangular plate shape on which the box-type container 1 can be placed, casters 33 provided at four corners of the lower surface of the base plate 32, and upper sides from three side portions of the base plate 32. And a fence 34 higher than the height of the box-shaped container 1 stacked in five stages. The lateral width of the inner housing space of the car 31 (distance between the opposing fences 34) is slightly larger than the lateral width of the short side wall portion 9 of the box-type container 1. For this reason, when the box-type container 1 is placed on the base plate 32, almost no gap is formed between each long side wall 8 and the fence 34.

  Further, the depth width of the inner housing space of the car 31 is slightly larger than the lateral width of the long side wall portion 8 of the box-type container 1. For this reason, when the box-shaped container 1 is placed on the base plate 32, almost no gap is formed between the short side wall portion 9 located on the back side of the car 31 and the fence 34. Thus, by designing the car 31 according to the outer dimensions of the box-shaped container 1, the car 31 can be miniaturized as much as possible, and the box-shaped containers 1 are stacked and transported on the car 31. By doing so, it is possible to move the wheel well and to reduce the storage space of the car 31.

  Further, when the box-shaped container 1 is taken out from the car 31, it is only necessary to allow a hand to enter between the fence 34 and the long-side side wall 8 or the back-side short-side side wall 9 of the box-shaped container 1. First, a finger is inserted into the second recess 22 through the first recess 21 from the short side wall 9 on the near side, and the finger is put on the locking surface 24 and pulled. At this time, if the hand inserted into the first recess 21 and the second recess 22 is moved upward and the support surface 25 is pushed up, the near side of the box-shaped container 1 can be lifted. In particular, when taking out the upper box-shaped container 1 out of the stacked box-shaped containers 1, the box-shaped containers 1 are relatively moved in the horizontal direction by floating the front side of the box-shaped containers 1 together. Can be released. In addition, since the locking surface 24 is inclined upward toward the center in the width direction of the long side wall 8, when the finger is put on the locking surface 24, It is easy to apply a force to. Then, by pulling (pulling) the box-shaped container 1 to the near side to some extent while floating, a space in which a hand can be inserted is formed between the box-shaped container 1 and the fence 34 of the car 31. Thereby, it becomes possible to place a hand on the handle 27 of the short side wall 9 on the back side through such a space. Then, the box-shaped container 1 is lifted by placing a hand on the pair of handles 27 and taken out from the car 31.

  In addition, when the handle 27 is formed in the pair of short side walls 9, when the box-shaped container 1 is placed on the car 31, the operator can move the arm 27 forward and backward. While holding, half or more of the box-shaped container 1 can be placed on the car 31 (on the base plate 32 or the box-shaped container 1 already mounted on the car 31). In other words, when adopting a configuration in which a handle is formed only on the long side wall 8, the handle is generally formed at the center in the width direction of the side wall to be formed. More than half of the box-shaped container 1 cannot be placed on the car 31. Therefore, when releasing the hand from the handle, the operator needs to hold the box-shaped container 1 so as not to fall from the car 31 at other parts of the body. For this reason, by forming the handle 27 on the pair of short side wall portions 9, it is possible to improve workability when the box-shaped container 1 is loaded and unloaded.

  As described above in detail, according to the present embodiment, the lateral width of the short side wall portion 9 is set on the outer surface side of the long side wall portion 8 within the range including the boundary portion with the short side wall portion 9. A first recess 21 is formed so as to be shaved, and a second recess that is recessed inward of the container relative to the first recess 21 adjacent to the lateral side central portion of the long side wall 8 of the first recess 21. 22 is formed. For this reason, a fingertip is hooked from the short side wall portion 9 side to the inner surface (locking surface 24) of the second recess 22 on the first recess 21 side, and the box-shaped container 1 is pulled out relatively smoothly to the front side. Can do. Further, even when the box-shaped container 1 is installed with the outer surface of the long side wall portion 8 being in close contact with the wall surface of the installation place, the second side via the first recess 21 is provided from the short side wall portion 9 side. A hand can be inserted into the recess 22. Accordingly, it is possible to improve workability when the box-shaped container 1 is pulled and moved. In addition, it is not necessary to secure a space for placing a hand on the side of the box-shaped container 1 on the side of the box-shaped container 1. Etc.) can be reduced.

  Further, by forming the first concave portion 21 and the second concave portion 22 below the upper edge portion of the long side wall portion 8, the container outward from the upper edge portion of the bottom surface of the first concave portion 21 and the second concave portion 22. A support surface 25 is provided that extends substantially orthogonally toward the top and defines the upper edge portions of the first recess 21 and the second recess 22. For this reason, the support surface 25 can be supported by moving the hand inserted in the 1st recessed part 21 and the 2nd recessed part 22 upwards, and the front side of the box-type container 1 can be supported by pushing up the support surface 25 as it is. Can float. By pulling out the box-shaped container 1 while floating the front side of the box-shaped container 1 in this way, it is possible to reduce the frictional resistance when pulling out the box-shaped container 1 and to improve workability.

  In particular, in the present embodiment, when the box-shaped containers 1 are stacked, they are configured to be engaged with each other in the horizontal direction to prevent misalignment (a stackable configuration). In order to slide the container 1, it is necessary to slightly lift the near side of the upper box-shaped container 1 to be slid. For this reason, the effect of making the near side of the box-shaped container 1 easy to float and improving the ease of taking out the box-shaped container 1 becomes more remarkable.

  In addition, when the box-shaped container 1 is pulled from the short side wall portion 9 side, the locking surface 24 that can be hooked with a finger is inclined upward toward the center in the lateral direction of the long side wall portion 8. Yes. For this reason, when pulling out the box-shaped container 1 while floating the near side of the box-shaped container 1, it becomes easy to apply an upward force to the locking surface 24. Therefore, the workability of pulling out the box-shaped container 1 can be improved. Further, a vertically extending boundary portion formed between the side portion of the short side wall portion 9 and the first recess 21 has a chamfered shape. For this reason, it is possible to make it easier to insert a hand into the first recess 21 from the side of the side wall 9 on the short side.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the said embodiment, although the 1st recessed part 21 and the 2nd recessed part 22 are formed in one long side side wall part 8, the side wall used as the object of formation of the 1st recessed part 21 and the 2nd recessed part 22 The numbers of the parts 8 and 9 and the first recesses 21 and the second recesses 22 are not particularly limited, and are appropriately designed according to usage conditions. For example, as shown in FIG. 8, the first concave portion 21 and the second concave portion 22 may be formed on the left and right side portions of the pair of long side wall portions 8. In this case, as shown in FIG. 9, when the box-shaped containers 1 are stacked on the car 31, the first concave portions 21 are respectively formed on the left and right sides of the short side wall portion 9 with respect to the opening on the near side without the fence 34. Will come. Thereby, when pulling out the box-shaped container 1 from the car 31, it is possible to insert a hand into the pair of left and right first recesses 21 and second recesses 22 and put a finger on the locking surface 24. Therefore, the box-shaped container 1 can be pulled out in a balanced manner using both hands instead of one hand, and workability can be improved.

  For example, as shown in FIG. 10, it is good also as forming the 1st recessed part 21 and the 2nd recessed part 22 with respect to the short side wall part 9. As shown in FIG. In this case, it is possible to insert a hand into the first concave portion 21 and the second concave portion 22 formed on the short side wall portion 9 from the long side side wall portion 8 side, put a finger on the locking surface 24 and pull the front side. it can. For this reason, even when the box-shaped container 1 is installed without a gap between the short-side side wall portion 9 and the wall surface of the installation place, the box-shaped container 1 is moved from the long-side side wall portion 8 side to the near side. Can be pulled out. Furthermore, as shown in FIG. 10, by forming the first recess 21 and the second recess 22 in the long side wall 8 and the short side wall 9, respectively, the short side wall 9 side and the long side are formed. The box-shaped container 1 can be pulled out to the near side by placing a finger on the locking surface 24 from either side of the side wall 8 side. For this reason, even if it changes the direction which installs the box-shaped container 1 suitably according to an installation place etc., the effect that the box-shaped container 1 can be pulled out comparatively smoothly to the near side can be exhibited. .

  (B) Furthermore, in the said embodiment, although the 1st recessed part 21 and the 2nd recessed part 22 are formed in the site | part below the up-down direction center part of the long side wall part 8, it is not limited to this structure, For example, the first concave portion 21 and the second concave portion 22 may be formed only at an intermediate position in the vertical direction or may be formed up to the upper edge portion of the long side wall portion 8. However, when the former configuration is adopted, dust and the like are likely to accumulate, and there is a possibility that the cleaning property and the moldability may be deteriorated. Therefore, the first concave portion 21 and the second concave portion 22 extend to the lower edge portion. It is desirable that In addition, since the support surface 25 is omitted when the latter configuration is adopted, instead of the first concave portion 21 and the second concave portion 22, a convex portion protruding outward from at least a part of the container. It is good also as providing (support part). However, as in the above-described embodiment, the first concave portion 21 and the second concave portion 22 are formed at a position below the upper side portion of the long side wall portion 8, thereby preventing a complicated shape and a decrease in strength. By forming the support surface 25, it is possible to improve workability when the front side of the box-shaped container 1 is floated.

  (C) In the above embodiment, the handle 27 is formed on the outer surface side of the pair of short side wall portions 9, but instead of or in addition to this configuration, the outer surface side of the long side wall portion 8 It is good also as forming a handle. Further, the handle 27 can be omitted. In addition, when employ | adopting the structure which abbreviate | omitted the handle 27 of the short side wall part 9, when taking out from the cart 31 after carrying the box-shaped container 1 on the cart 31, it is the short side wall part. After hooking a finger on the locking surface 24 through the first recess 21 and the second recess 22 from the 9 side and pulling it out to some extent, turn the arm to the back of the box-shaped container 1, and the short side wall portion The box-shaped container 1 can also be lifted by placing a hand on the lower surface of the bottom wall 7 from the lower side of 9.

  In addition, although only the space which piles up the box-shaped container 1 in one row is formed in the cage | basket | car 31 of the said embodiment, it is comprised so that the box-shaped container 1 can be piled up and conveyed in multiple rows. Also good. In this case, even if the long side wall portions 8 of the box-shaped containers 1 adjacent to each other are in contact with each other, the hand is advanced to the second recess 22 through the first recess 21 and the finger is placed on the locking surface 24. The box-type container 1 can be pulled out to the front side.

  (D) In the above-described embodiment, the in-wall housing portion 11 capable of housing a cooling agent or the like is formed on the inner surface side of the long side wall portion 8, but the in-wall housing portion 11 may be omitted. In addition, the articles accommodated in the box-type container 1 are not particularly limited, and may include industrial parts having complicated shapes in addition to foods that require temperature management.

  Moreover, in the said embodiment, the boundary part of the bottom face of the 1st recessed part 21 and the side part of the short side wall part 9 and the boundary part of the bottom face of the 1st recessed part 21 and the locking surface 24 are round chamfering shapes. However, other chamfered shapes (such as a chamfered shape) may be used, or the chamfered shape may not be used.

  (E) In the above embodiment, the box-shaped container 1 including the lid member 4 detachably attached to the container body 2 is embodied.
