Japanese Patent Laying-Open No. 2015-3738

  By the way, regarding the assembling operation of the container that is used by assembling the bottom wall constituting portion and the side wall portion, further improvement in workability is demanded.

  The present invention has been made to solve the above-described problems and the like, and an object thereof is to provide a container capable of improving the assembly workability.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A bottom wall component having a substantially rectangular shape in plan view;
A side wall portion standing above each side portion of the bottom wall constituting portion,
The side wall portion includes a plurality of insertion portions protruding downward from a lower side portion,
The bottom wall constituting portion includes a plurality of inserted portions that open upward and are capable of inserting the insertion portions.
The insertion portion includes a locking portion,
The inserted portion includes a locked portion that is locked with the locking portion;
With respect to at least one of the side wall portions, as the plurality of insertion portions provided on the side wall portion, a first insertion portion and a second insertion having a longer protruding length than the first insertion portion from the side wall portion With
The bottom wall component is
When the first insertion portion is inserted into the insertion target portion, the first insertion portion comes into contact with a first contact portion of a first engagement portion that is the engagement portion of the first insertion portion, and the first engagement portion A first abutted portion that displaces
When the second insertion portion is inserted into the insertion target portion, the second insertion portion comes into contact with a second contact portion of a second engagement portion that is the engagement portion of the second insertion portion, and the second engagement portion A second abutted portion that displaces
When the side wall portion including the first insertion portion and the second insertion portion and the corresponding side portion of the bottom wall constituting portion are arranged in parallel vertically,
The distance between the lower end portion of the first insertion portion and the corresponding insertion port of the inserted portion, and the distance between the lower end portion of the second insertion portion and the corresponding insertion port of the inserted portion. Unlike, and
The distance between the first contact portion and the first contacted portion is the same as the distance between the second contact portion and the second contacted portion. A container characterized by being made.

  According to the means 1, the side wall portion is provided with the first insertion portion and the second insertion portion having different downward projecting lengths at the lower side portion thereof, and when the side wall portion is attached to the bottom wall constituting portion, First, the distal end (lower end) of the second insertion part is inserted into the corresponding inserted part, and then the distal end of the first insertion part is inserted into the corresponding inserted part. For this reason, in the operation of inserting the plurality of insertion portions of the side wall portion into the plurality of insertion portions of the bottom wall constituting portion, the insertion portion to be inserted first into the insertion portion among the plurality of insertion portions is the second insertion. It is possible to reduce the number of insertion parts that are inserted (substantially) at the same time into the inserted part. Therefore, there are many insertion parts provided in the side wall part, and when attaching the side wall part to the bottom wall constituting part, all the insertion parts are aligned with the corresponding inserted parts, and are inserted (almost) simultaneously. Workability can be improved as compared with the configuration in which the control is performed. In particular, since the second insertion portion protrudes downward from the first insertion portion, the second insertion portion only needs to be aligned with the corresponding insertion portion when the side wall portion is attached to the bottom wall constituting portion. This makes it easy to recognize this, and the operation of aligning and inserting can be performed relatively easily. Furthermore, after the tip of the second insertion portion is inserted into the insertion portion, the second insertion portion is inserted into the insertion portion as it is, so that the first insertion portion and the corresponding insertion portion The first insertion portion can be smoothly inserted into the corresponding inserted portion without much awareness of the positional relationship. As a result, it is possible to improve the assembly workability of the container.

  Further, when the side wall portion is attached to the bottom wall constituting portion, the first insertion portion and the first locking portion and the second locking portion of the second insertion portion are the first contact portion and the first In the two abutting portions, the first abutting portion and the second abutting portion of the bottom wall constituting portion are abutted (the first locking portion and the second locking portion are the first abutting portions). Overcoming the abutted part and the second abutted part, it becomes an appearance to be locked to the locked part). According to this means, when the side wall portion is arranged in parallel above the corresponding side portion of the bottom wall constituting portion, the distance between the first contact portion and the first contacted portion, and the second The distance between the contact portion and the second contacted portion is the same. For this reason, by arranging the side wall portion in parallel above the corresponding side portion of the bottom wall constituting portion and lowering it as it is to insert the insertion portion into the insertion portion, the first contact portion and the first The timing at which the abutted portion comes into contact with the timing at which the second abutting portion and the second abutted portion abut can be matched. Therefore, when attaching the side wall portion to the bottom wall constituting portion, all the stress provided to the side wall portion by the respective engaging portions as the first contact between the side wall portion and the bottom wall constituting portion is received from the bottom wall constituting portion. It is possible to disperse to the locking portions. As a result, it is possible to reduce the risk of damage to the locking portion or the like when the side wall portion is attached to the bottom wall constituting portion.

  It should be noted that “the height positions of the insertion openings of the plurality of inserted portions are all the same”. In this case, the surface of the bottom wall constituent portion where the insertion opening is formed, that is, the contact surface with the lower side portion of the side wall portion can be a flat surface. Therefore, for example, compared with a case where the forming surface of the insertion port is uneven in the bottom wall constituent portion, it is possible to dramatically reduce a situation in which a gap is formed between the bottom wall constituent portion and the side wall portion. .

Mean 2. The height position of the first contact portion is the same as the height position of the second contact portion,
The container according to claim 1, wherein the height position of the first abutted portion and the height position of the second abutted portion are the same.

Furthermore, when the height positions of the first contact portion and the second contact portion can be aligned, and the lower side portion of the bottom wall portion extends in a substantially horizontal direction, the first insertion portion and the second insertion portion The length from the root part to the first contact part and the second contact part can be made uniform. Therefore, for example, the length of the first insertion part and the base part of the second insertion part to the first contact part and the second contact part is different, resulting in deformation of the part. When the side wall portion is attached to the bottom wall constituent portion, all engagement factors provided on the side wall portion are subjected to the stress that the engaging portion provided on the side wall portion receives from the bottom wall constituent portion. It is possible to avoid a situation where the operational effect of dispersing (substantially evenly) in the stop portion is reduced.

Means 3. The insertion portion includes an elastic piece extending downward from a lower side portion of the side wall portion, and a protection portion extending along the elastic piece on a side of the elastic piece, and the locking portion is provided on the elastic piece. In configuration,

The upper side portion (boundary portion between the inner surface and the upper surface) of the outer wall portion 50 of the insertion portion 45 into which the first insertion portion 61 is inserted is referred to as a “first contact portion 67”, and the second insertion portion 64 is The upper side portion (boundary portion between the inner surface and the upper surface) of the outer wall portion 50 of the inserted portion 45 to be inserted is referred to as a “second contacted portion 68”.

  With the above configuration, when the long side wall portion 3 is attached to the bottom wall component 2, the long side wall 3 and the corresponding long side of the bottom wall component 2 are shown in FIG. When the parts are arranged in parallel up and down (in a separated state), the distance between the lower end part of the first insertion part 61 (protection part 19) and the insertion port 46 of the corresponding insertion part 45 is The distance between the lower end of the second insertion portion 64 (protection portion 19) and the insertion port 46 of the corresponding inserted portion 45 is longer (the insertion port 46 is not shown in FIG. 46 exists in the same height position as the receiving flange part 43). On the other hand, as shown in FIGS. 5, 8, and 10, the first contact portion 63 (the inclined portion 17 b of the first locking portion 62) of the first insertion portion 61 and the first contacted portion 67. (The corresponding insertion port 45 of the inserted portion 45), the second abutting portion 66 (the inclined portion 17b of the second locking portion 65), and the second abutted portion 68 (the corresponding covered portion). The distance between the insertion portion 45 and the insertion slot 46) is the same. In the present embodiment, the height position of the insertion port 46 of the inserted portion 45, the height position of the first contacted portion 67, and the height position of the second contacted portion 68 are the same. ing.

  Also, the main locking surface 17a of the main locking portion 17 (first locking portion 62) of the first insertion portion 61 and the main locking surface 17 (second locking portion 65) of the second insertion portion 64 are main. The locking surface 17a is at the same height position. In addition, the height position of the sub locking surface 18 a of the sub locking portion 18 is the same in the first insertion portion 61 and the second insertion portion 64. In addition, as shown in FIG. 11 etc., the lower side part connected with the long side insertion part 12 among the long side base parts 11 of the long side wall part 3 extends in the longitudinal direction of the long side wall part 3. It is comprised in rib shape, and the substantially triangular shape which connects between the said lower side part and the outer surface of the long side base part 11 on the opposite surface side of the site | part in which the 2nd insertion part 64 was provided among the said lower side parts. Auxiliary ribs 24 are provided. Further, as shown in FIG. 14 and the like, the two short side insertion portions 33 provided on the short side wall portion 4 both have the same shape as the first insertion portion 61.

  As shown in FIGS. 5, 18, etc., the lower flange portion 44 of the bottom wall constituting portion 2 is located outside the bottom wall portion 41 in the range where the inserted portion 45 into which the second insertion portion 64 is inserted is provided. Corresponding to the bottom flange portion 69 provided so as to extend in the opposite direction, both ends of the long side portion of the bottom wall constituting portion 2 and the short side portion, at a position above the bottom flange portion 69. The retraction flange part 70 extended horizontally, the bottom flange part 69, and the connection part 71 which connects between the edge parts of the retraction flange part 70 diagonally are provided. With this configuration, a recess (hereinafter referred to as a “stage stacking recess 72”) is provided between the lower surfaces of the retracting flange portion 70 and the connecting portion 71 and the outer surface of the vertical wall portion 42. In addition, the lower flange portion 44 in the range where the inserted portion 45 into which the first insertion portion 61 of the long side wall portion 3 is inserted is a retraction flange portion 70.

  In addition, the formation range of the stacking concave portion 72 (the retracting flange portion 70 and the connecting portion 71) includes the upper surface and the long side wall portion 4 (the short side base portion 31 and the connecting wall portion 32). This corresponds to the range in which the long side convex portion 14 of the side side wall portion 3 extends, and as shown in FIG. 19, when the containers 1 in an assembled state are stacked up and down (stacked), The upper part of the short side wall 4 of the side container 1 and the long side convex part 14 are inserted into the stacking concave part 72 of the upper container 1. As a result, the lower flange portion 44 of the upper container 1 is supported in contact with the upper surfaces of the side wall portions 3 and 4 of the lower container 1 (see FIG. 21), and as shown in FIGS. Of the bottom wall constituting portion 2 of the upper container 1, a portion in a range where the stacked concave portions 72 are formed is inserted inside the side wall portions 3 and 4 of the lower container 1. In the present embodiment, the upper side of the short side wall portion 4 (the short side base portion 31 and the connecting wall portion 32) and the long side side convex portion 14 of the long side wall portion 3 are stepped stacked convex portions. Is configured.

  In addition, the side wall parts 3 and 4 erected on the bottom wall constituting part 2 extend in a substantially vertical direction, and the circumferential shape provided so as to extend the vertical wall part 42 of the bottom wall constituting part 2 upward. The upper edge portion of the inner surface of the ridge portion 55 and the inner surfaces of the side wall portions 3 and 4 are substantially flush. For this reason, when stacking the containers 1, the vertical wall portion 42 in the stacking recess 72 of the upper container 1 and the side wall portions 3, 4 of the lower container 1 do not interfere with each other, as shown in FIGS. As shown in FIG. 21, the upper part of the inner surfaces of the side wall parts 3 and 4 (the part into which the bottom wall constituting part 2 of the upper container 1 is inserted inside) is approximately the thickness of the vertical wall part 42 and the outer periphery of the container 1. It is provided at a position displaced to the side.

  Further, as shown in FIG. 5 and the like, both end portions (short side portions) in the longitudinal direction of the bottom wall portion 41 of the bottom wall constituting portion 2 are slightly inclined upward toward the outer peripheral side of the bottom wall constituting portion 2. It is extended (tapered and not grounded). For this reason, for example, when the container 1 is transported on a roller conveyor, the interference between the bottom wall constituting portion 2 and the roller of the roller conveyor is suppressed by matching the longitudinal direction of the container 1 with the transport direction. 1 smooth conveyance becomes possible.

  As described above in detail, according to the present embodiment, the long side wall portion 3 includes the first insertion portion 61 and the second insertion portion 64 having different downward projecting lengths in the lower side portion. When attaching the long side wall portion 3 to the bottom wall constituting portion 2, first, the distal end (lower end) of the second insertion portion 64 is inserted into the corresponding inserted portion 45, and then the first insertion portion 61 The tip is inserted into the corresponding inserted portion 45. For this reason, in the operation | work which inserts the some long side insertion part 12 (this example four) of the long side side wall part 3 in the some insertion part 45 of the bottom wall structure part 2, a some long side side The long side insertion portion 12 that is inserted first into the insertion portion 45 in the insertion portion 12 is limited to the second insertion portion 64, and the long side that is inserted into the insertion portion 45 first (almost) simultaneously. The number of side insertion parts 12 can be reduced. Therefore, the number of the long side side insertion portions 12 provided in the long side wall portion 3 is large, and when the long side wall portion 3 is attached to the bottom wall constituting portion 2, all the long side insertion portions 12 are provided. Can be aligned with the corresponding inserted portion 45 and can be inserted (substantially) at the same time to improve workability. In particular, since the second insertion portion 64 protrudes downward from the first insertion portion 61, the second insertion portion 64 is attached to the corresponding portion of the second insertion portion 64 when attaching the long side wall portion 3 to the bottom wall constituting portion 2. While making it easy to recognize that it is sufficient to align with the insertion portion 45, the operation of aligning and inserting can be performed relatively easily. Further, after the distal end of the second insertion portion 64 is inserted into the insertion portion 45, the second insertion portion 64 is inserted directly into the insertion portion 45 to correspond to the first insertion portion 61. The first insertion portion 61 can be smoothly inserted into the corresponding insertion portion 45 without being much conscious of the positional relationship with the insertion portion 45. As a result, the assembly workability of the container 1 can be improved.

  Further, when the long side wall portion 3 is attached to the bottom wall constituting portion 2, the first insertion portion 61 and the first engagement portion 62 and the second engagement portion 65 of the second insertion portion 64 are In the first abutting portion 63 and the second abutting portion 66, the first abutting portion 67 and the second abutting portion 68 of the bottom wall constituting portion 2 are abutted (first relation). The stop portion 62 and the second locking portion 65 get over the first contacted portion 67 and the second contacted portion 68 and are locked to the main locked portion 47). . In the present embodiment, when the long side wall portion 3 is disposed in parallel above the corresponding long side portion of the bottom wall constituting portion 2, the first contact portion 63 and the first contacted portion 67 The distance between the second contact portion 66 and the second contacted portion 68 is the same. For this reason, the long side wall portion 3 is arranged in parallel above the corresponding long side portion of the bottom wall constituting portion 2 and is lowered as it is to insert the long side insertion portion 12 into the insertion portion 45. Thus, the timing at which the first abutting portion 63 and the first abutted portion 67 abut can be matched with the timing at which the second abutting portion 66 and the second abutted portion 68 abut. it can. Therefore, when the long side wall 3 is attached to the bottom wall component 2, the main locking portion 17 serves as a first contact between the long side wall 3 and the bottom wall component 2 from the bottom wall 2. The stress to be received can be distributed to all the first locking portions 62 and the second locking portions 65 provided on the long side wall portion 3. As a result, it is possible to reduce the risk of damage to the main locking portion 17 (the first locking portion 62 and the second locking portion 65) during the work of attaching the long side wall portion 3 to the bottom wall constituting portion 2. Can do.

  In addition, the height positions of the insertion ports 46 of the plurality of inserted portions 45 are configured to be the same. For this reason, the surface in which the insertion port 46 is formed among the bottom wall structure part 2, ie, the contact surface with the lower side part of the side wall parts 3 and 4, can be made into a flat surface. Therefore, for example, compared to the case where the formation surface of the insertion port 46 is uneven in the bottom wall constituting portion 2, a situation in which a gap is formed between the bottom wall constituting portion 2 and the side wall portions 3 and 4 is dramatically improved. Can be reduced.

  Further, the height position of the first contact portion 63 (inclined portion 17 b) of the first locking portion 62 of the first insertion portion 61 and the second contact portion of the second locking portion 65 of the second insertion portion 64. 66 (inclined portion 17b) has the same height position, and the first abutted portion 67 (the opening edge of the insertion port 46, which is the boundary between the upper surface and the inner surface of the outer wall portion 50). And the height position of the second contacted portion 68 (the opening edge of the insertion port 46 and the boundary portion between the upper surface and the inner surface of the outer wall portion 50) is the same. Thus, by making the height positions of the first abutted portion 67 and the second abutted portion 68 uniform, the shape of the bottom wall constituting portion 2 can be prevented from becoming complicated. Furthermore, the height positions of the first contact portion 63 and the second contact portion 66, and consequently the root portion of the elastic piece 16 of the first insertion portion 61 and the attachment of the elastic piece 16 of the second insertion portion 64. The length from the root portion to the first contact portion 63 and the second contact portion 66 can be made uniform. Therefore, for example, the lengths of the elastic pieces 16 of the first insertion portion 61 and the second insertion portion 64 to the first contact portion 63 and the second contact portion 66 are different. When the elastic pieces 16 are easily deformed and the like, when the long side wall portion 3 is attached to the bottom wall constituting portion 2, each of the first locking portions 62 and the second locking portions 65 is provided on the bottom wall. The effect of distributing (substantially evenly) the stress received from the component part 2 to all the first locking parts 62 and the second locking parts 65 provided on the long side wall part 3 is reduced. Such a situation can be avoided.

  Further, the long side insertion portion 12 and the short side insertion portion 33 include an elastic locking piece 15 and a protection portion 19 provided so as to surround the elastic locking piece 15. In addition to protecting the elastic locking piece 15, the side wall portions 3, 4 with respect to the bottom wall constituting portion 2 during the operation of inserting the long side insertion portion 12 and the short side insertion portion 33 into the insertion portion 45 are provided. Positioning can be performed more reliably and smoothly. Further, since the first contact portion 63 and the second contact portion 66 are provided in the inclined portion 17b, the first contact portion 63 and the second contact portion 66 are the first contacted portion. 67 and the second abutted portion 68, the elastic piece 16 can be elastically deformed relatively smoothly, and the first locking portion 62 and the second locking portion 65 (the main locking portion) 17) Displace the first locking part 62 and the second locking part 65 relatively smoothly so that the first and second contact parts 67 and 68 can get over relatively. Can do.

  Further, the receiving flange portion 43, the lower flange portion 44, and the vertical wall portion 42 are connected by the lateral wall portion 49 and the outer wall portion 50 that constitute the inserted portion 45. For this reason, the rigidity of the receiving flange part 43, the lower flange part 44, and the to-be-inserted part 45 can be raised synergistically. Therefore, deformation and damage of the receiving flange portion 43, the lower flange portion 44, and the inserted portion 45 can be suppressed. In particular, among the lower flange portions 44, the bottom flange portion 69 provided so as to extend the bottom wall portion 41 outward is a bottom wall portion when the container 1 is installed on an installation surface such as a floor surface. 41 is grounded to the installation surface. Therefore, when the receiving flange portion 43 receives a load from the long side wall portion 3, the bottom flange portion 69 supported by the installation surface and the lateral wall of the insertion portion 45 into which the second insertion portion 64 is inserted. The part 49 and the outer wall part 50 cooperate to support the receiving flange part 43 more reliably (deformation of the receiving flange part 43 and the like). On the other hand, when the bottom flange portion 69 receives a load from the installation surface, the lateral wall portion 49 and the outer wall portion 50 of the inserted portion 45 into which the second insertion portion 64 is inserted, and the receiving flange portion 43 By cooperating, deformation of the bottom flange portion 69 can be prevented.

  Further, for example, instead of omitting the configuration in which the lateral wall portion 49 and the outer wall portion 50 are provided so as to connect the receiving flange portion 43 and the lower flange portion 44, the same strength can be increased. As compared with a case where a reinforcing rib capable of being provided is provided separately, the configuration on the outer peripheral surface side of the bottom wall constituting portion 2 can be simplified. Furthermore, it is possible to easily secure a space for providing an information portion (printing surface, card holder setting portion, etc.) having predetermined information on the outer peripheral surface of the bottom wall constituting portion 2 (the outer surface of the vertical wall portion 42). In addition, by providing the bottom flange part 69, the ground contact area of the container 1 can be increased and the installation state can be stabilized. In particular, when a downward force is applied to the long side wall 3, it is possible to prevent the container 1 from being tilted more reliably.

  In addition, on the lower surface side of the bottom wall constituting portion 2, a stacking recess 72 is provided corresponding to both ends of the long side portion and the short side portion, and when the containers 1 are stacked, The upper side of the short side wall part 4 (the short side base part 31 and the connecting wall part 32) of the lower container 1 and the long side convex part 14 are inserted into the stacking recess 72 of the container 1 of FIG. It has become so. Thereby, while the part of the range in which the stacking recessed part 72 was formed among the bottom wall structure parts 2 of the upper container 1 is inserted inside the side wall parts 3 and 4 of the lower container 1, the upper container 1 The lower flange portion 44 can be reliably supported on the upper surfaces of the side wall portions 3 and 4 of the lower container 1. Therefore, the containers 1 can be stably stacked, and the transportation and storage efficiency can be improved.

  Moreover, since the long side insertion part 12 provided in the both ends of the long side wall part 3 is the 1st insertion part 61, even when the height of the bottom wall structure part 2 is low, a bottom wall structure part Corresponding to both end portions of the long side portion of the two, the stacking recess 72 can be formed at a position below the inserted portion 45 into which the first insertion portion 61 is inserted. Furthermore, the structure regarding stacking can be suitably provided compared with the case where the long side side convex part 14 is provided in the horizontal width direction center part of the long side wall part 3. In addition, both longitudinal ends of the bottom surface of the bottom wall portion 41 can be configured to be tapered.

  Further, the lateral wall portion 49 and the outer wall portion 50 of the inserted portion 45 into which the first insertion portion 61 is inserted are provided so as to connect between the receiving flange portion 43 and the retracting flange portion 70. The strength of the lateral wall portion 49 and the outer wall portion 50 of the insertion portion 45 into which the flange portion 43, the retracting flange portion 70, and the first insertion portion 61 are inserted can be increased synergistically. Accordingly, when the containers 1 are stacked, the horizontal wall portion 49 of the inserted portion 45 into which the receiving flange portion 43, the retracting flange portion 70, and the first insertion portion 61 are inserted in a portion corresponding to the stacking recess 72. And the situation that the outer wall part 50 will deform | transform etc. can be suppressed.

  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 above-described embodiment, four long side insertion portions 12 of the long side wall portion 3 are provided, two of which are configured as the second insertion portions 64, and the short side insertion of the short side wall portion 4 is performed. Two parts 33 are provided, both of which are configured to have the same shape and size as the first insertion part 61, but the long side insertion part 12 provided on each side wall part 3, 4, and the short side insertion The number and arrangement of the portions 33 and the ratio of the second insertion portions 64 are not particularly limited, and the design can be changed as appropriate according to the lateral width of the side wall portions 3 and 4. For example, the arrangement of the long side insertion portion 12 may be made unequal, and a space such as a printing surface or a card holder installation portion may be secured on the outer surface of the vertical wall portion 42 of the bottom wall constituting portion 3. . However, when the number of the long side insertion portions 12 and the short side insertion portions 33 provided in the predetermined side wall portions 3 and 4 is two or less, like the short side wall portion 4 of the above embodiment, The shapes and sizes of the long side insertion portion 12 and the short side insertion portion 33 may be unified. Furthermore, for example, when the stacked recess 72 is not formed below the short side insertion portion 33, the short side insertion portion 33 can be configured to have the same shape and size as the second insertion portion 64. .

  In addition, in the said embodiment, regarding the long side insertion part 12 of a pair of opposing long side wall part 3, it is comprised so that two 1st insertion parts 61 and two 2nd insertion parts 64 may be provided, respectively. (The pair of opposite long side wall portions 3 are the same product), but at least one of the side wall portions 3 and 4 constituting the container 1 is not only the first insertion portion 61, What is necessary is just to be comprised so that the 2 insertion part 64 may also be comprised. In particular, the side wall portion including the first insertion portion 61 and the second insertion portion 64 is attached to the bottom wall constituting portion 2 before the other side wall portion when the container 1 is assembled. It is good also as being a side wall part which can be made to stand by itself independently.

In this case, when attaching the predetermined side wall portions 3 and 4 to the bottom wall constituting portion 2, the long side insertion portion 12 and the short side insertion portion 33 out of the insertion portion 45 of the bottom wall constituting portion 2. First, the number of the long side insertion portions 12 and the short side insertion portions 33 that are inserted into the insertion portion 45 at the same time is reduced as much as possible, and the second insertion portion 64 (as compared to the case where there is one second insertion portion 64). It is possible to perform the positioning in a state in which the distal end portion is inserted into the insertion portion 45 more accurately.

  Furthermore, in the said embodiment, although the long side insertion part 12 provided in the both sides of the long side wall part 3 is comprised as the 1st insertion part 61, it is good also as the 2nd insertion part 64. FIG. However, in the case where the height of the bottom wall component 2 is low and the stacked structure is provided at the corner of the container 1, the long side insertion portion provided at both ends of the long side wall 3 By setting 12 as the first insertion portion 61, a space for the stacking recess 72 is secured below the first insertion portion 61.

  (B) In the above embodiment, with respect to the long side insertion portion 12 of the long side wall portion 3, the height position of the first contact portion 63 of the first insertion portion 61 (first locking portion 62), The inserted portion into which the first insertion portion 61 and the second insertion portion 64 are inserted is the same as the height position of the second contact portion 66 of the two insertion portions 64 (second locking portions 65). 45, the height position of the first abutting portion 67 and the height position of the second abutting portion 68 are the same, but the first insertion portion 61 and the second insertion portion 64 If the relative distance between the first abutting portion 63 and the second abutting portion 66 and the first abutted portion 67 and the second abutted portion 68 of the corresponding inserted portion 45 is equal. Good. For example, the second abutting portion 66 is configured to be at a position lower by a specific distance than the first abutting portion 63, and the second abutted portion 68 is more specific than the first abutted portion 67. It is good also as being comprised so that it may become a low position.

  Moreover, in the said embodiment, although the 1st to-be-contacted part 67 and the 2nd to-be-contacted part 68 are comprised by the opening edge of the insertion port 46, the 1st to-be-contacted part 67 and the 1st The two abutted portions 68 may be provided below the insertion port 46. Furthermore, in the said embodiment, although the height position of the insertion port 46 of the to-be-inserted part 45 is the same, the timing at which the 1st insertion part 61 is inserted in the insertion port 46, and the 2nd insertion part 64 are the same. Is inserted at the insertion slot 46, the insertion slot 46 into which the first insertion section 61 is inserted and the insertion section at which the second insertion section 64 is inserted. The height of the insertion opening 46 of the part 45 may be different.

  In addition, the height position of the connection part with the long side base part 11 of the 1st insertion part 61 and the 2nd insertion part 64, and also the length of the 1st insertion part 61 and the 2nd insertion part 64 are specifically limited. Instead, the second insertion portion 64 only needs to have a lower end portion, which is a distal end portion in the insertion direction to the insertion portion 45, positioned below the first insertion portion 61. What is necessary is just to be comprised so that the distance between the part 63 and the 2nd contact part 66, and the 1st to-be-contacted part 67 and the 2nd to-be-contacted part 68 corresponding to each may become the same.

  (C) In the said embodiment, the shape of the elastic locking piece 15 is not specifically limited, For example, space, such as a printing surface and a card holder installation part, is formed in the outer surface of the vertical wall part 42 of the bottom wall structure part 2. FIG. In order to ensure, the lateral width of the elastic locking piece 15 and thus the protection part 19 may be narrowed, or the sub locking part 18 may be omitted. Although not particularly mentioned in the above embodiment, when attaching the long side wall portion 3 to the bottom wall constituting portion 2, the bottom wall constituting portion 2 (the sub wall constituting portion 2) of the sub locking portions 18 of the first insertion portion 61. The height position of the portion of the locked portion 48 that first contacts the surface to be locked) and the bottom wall constituting portion 2 (sub-locked portion) of the sub-locking portion 18 of the second insertion portion 64. The height position of the portion of the locking portion 48 on the opposite side to the locked surface) and the first contact portion is the same, and the sub-locking of the inserted portion 45 into which the first insertion portion 61 is inserted. The height position of the portion 48 (the locked surface and the surface on the opposite side) and the sub-locked portion 48 (the locked surface and the locked surface of the inserted portion 45 into which the second insertion portion 64 is inserted) The height position of the opposite surface) may be the same. In this case, as with the main locking portion 17, the sub locking portion 18 receives from the bottom wall forming portion 2 when the long side wall portion 3 is attached to the bottom wall forming portion 2. The stress can be distributed to the plurality of sub locking portions 18. As a result, it is possible to reduce the risk of damage to the sub-engagement portion 18 when attaching the long side wall portion 3 to the bottom wall constituting portion 2.

  (D) Further, the shape of the protection portion 19 is not particularly limited, and for example, vertically on one side or both sides of the elastic locking piece 15 along the side portion of the elastic piece 16. You may comprise the protection part 19 only with the pillar part 20 extended. However, the protruding length from the lower side portion of the side wall portions 3 and 4 (long side base portion 11 and short side base portion 31) of the protection portion 19 is from the lower side portion of the side wall portions 3 and 4 of the elastic locking piece 15. It is desirable that the protrusion length be equal to or longer than. In this case, the effect of protecting the elastic locking piece 15 is more reliably achieved. The elastic piece 16 of the elastic locking pieces 15 is provided in the range of the thickness of the protection part 19, and at least a part of the main locking surface 17 a of the main locking part 17 and the first contact part 63. In addition, the second contact portion 66 is desirably provided outside the thickness range of the protection portion 19. In this case, the protective portion 19 prevents the elastic piece 16 from being displaced more than necessary and in an unintended direction, thereby protecting the elastic piece 16 and, due to vibrations of the container 1 and the like, the elastic piece 16 It is possible to prevent a situation in which the locking state between the main locking portion 17 and the main locked portion 47 is released when 16 is pressed by the bottom wall constituting portion 2 and deformed.

  The protection unit 19 can be omitted. In this case, for example, by making the protruding lengths of the elastic pieces 16 of the first insertion portion 61 and the second insertion portion 64 different, the second insertion portion 64 is attached to the first insertion portion 64 during the attachment work of the long side wall portion 3. You may comprise so that it may insert in the to-be-inserted part 45 ahead of the insertion part 61. FIG.

  (E) In the above embodiment, the lateral wall portion 49 and the outer wall portion 50 that constitute the inserted portion 45 are provided so as to connect the receiving flange portion 43, the lower flange portion 44, and the vertical wall portion 42. However, for example, when the height of the bottom wall constituting portion 2 is relatively high, the lateral wall portion 49 and the outer wall portion 50 may be configured to be separated from the lower flange portion 44. However, the lateral wall portion 49 is provided so as to connect the receiving flange portion 43 and the lower flange portion 44, and the rigidity of the receiving flange portion 43, the lower flange portion 44, and the inserted portion 45 is synergistically. It is desirable to increase.

  (F) In the above embodiment, the container 1 is made of polypropylene, but may be made of other resin materials such as polyethylene, PET, and polyamide.
