Further, the pocket bottom wall overlapping portion 50 protruding from the second short side wall 14B is an outer portion of the pair of stacked support protrusions 31, 31 provided on the second short side wall 14B (second short side wall). 14B in the width direction outer side) (see FIG. 3). More specifically, the pocket bottom wall overlapping portion 50 that protrudes from the first short side wall 14A is a protrusion configuration vertical position that is disposed on the center side in the width direction of the first short side wall 14A in the stacked support protrusion 31. The pocket bottom wall overlapping portion 50, which is configured by the extended rib 51 extending from the rib 32 (see FIG. 4) and protrudes from the second short side wall 14 </ b> B, is the second short side wall 14 </ b> B of the stacked support protrusions 31. It is comprised by the extension rib 51 extended from the protrusion structure vertical rib 32 arrange | positioned in the width direction outer side (refer FIG. 6).

  When the containers 10 are stacked in a stacking state, the inward portions of the pair of stacking support protrusions 31 and 31 provided on the first short side wall 14A of the upper container 10 are on the lower side. 10 is disposed on the outer side portion of the pair of receiving pockets 41, 41 provided on the first short side wall 14A of the container 10 (the uppermost container 10 and the middle of the three containers 10 in FIG. 10). Container 10). Although not shown, the outer portion of the pair of stacked support projections 31, 31 provided on the second short side wall 14 </ b> B of the upper container 10 is the second short side of the lower container 10. It arrange | positions on the inward part of a pair of receiving pockets 41 and 41 provided in the side wall 14B. Then, a pair of pocket bottom wall overlapping portions 50 and 50 (extension ribs 51 and 51) protruding from the first short side wall 14A of the upper container 10 are provided on the first short side wall 14A of the lower container 10. A pair of pocket bottom wall overlapping portions 50, 50 (see FIG. 11B) that are received in the pair of receiving pockets 41, 41 provided and project from the second short side wall 14B of the upper container 10 ( The extension ribs 51, 51) are received in a pair of receiving pockets 41, 41 provided in the second short side wall 14B of the lower container 10 (see FIG. 11A).

  Here, as shown in FIG. 11 (A), the pair of pocket bottom wall overlapping portions 50 and 50 (extension ribs 51 and 51) protruding from the second short side wall 14B is a pair of receiving pockets 41 and 41. Of the inner side surfaces of the second short side direction 14B so as to sandwich the surface facing the outer side in the width direction. As shown in FIG. 11B, the pocket bottom wall overlapping portions 50 and 50 protruding from the first short side wall 14A are the first short side wall 14A of the inner side surfaces of the pair of receiving pockets 41 and 41. It is arrange | positioned so that it may be pinched | interposed into the surface which faces the width direction center side. Thus, in the container 10 of this embodiment, when stacked in a stacking state, a pair of pocket bottom wall overlapping portions 50, 50 formed on each short side portion of the upper container 10 is a pair. Therefore, the upper side container 10 is restrained from moving in the short side direction with respect to the lower side container 10.

  As shown in FIG. 5, the end of the extension rib 51 on the side close to the outer side surface (side wall 12) of the container body 10 </ b> H is more than the portion positioned away from the outer side surface of the container body 10 </ b> H with respect to the end portion. The thick portion 52A is thick. Further, the end portion of the extension rib 51 on the side close to the stacking support protrusion 31 (protrusion-forming lateral rib 33) is thicker than the portion positioned away from the stacking support protrusion 31 with respect to the end portion. It is the thick part 52B which became meat. As described above, in the present embodiment, the thickened portions 52 </ b> A and 52 </ b> B are formed on the extension rib 51, thereby increasing the strength of the extension rib 51. The thick portion 52A is formed in a triangular shape that becomes thicker as it approaches the outer surface of the container body 10H, and the thick portion 52B is a triangular shape that becomes thicker as it approaches the buildup support protrusion 31. Is formed.

  In addition, the lower end surface of the extension rib 51 on the side away from the outer surface of the container body 10H is an R surface 53 that is curved in an arc shape that faces upward as it is away from the outer surface of the container body 10H. In the container 10 of this embodiment, the R surface 53 is formed on the extension rib 51, so that the upper container 10 can be smoothly taken out from a plurality of containers 10 stacked in a stacking state or a nesting state. It becomes. Further, since the R surface 53 is formed on the extension rib 51, when the container 10 is dragged by lifting one side in the long side direction of the container 10, the extension rib 51 becomes difficult to be caught on the ground or the like, and the container 10 is smooth. It is possible to move to.

  As shown in FIG.2 and FIG.3, in the container 10 of this embodiment, the positioning rib 61 protrudes from the outer surface below the stacking support protrusion 31 in the container main body 10H. The positioning rib 61 has a smaller amount of protrusion from the outer surface of the container body 10H than the extension rib 51 described above, and the container body 10H (details) of the lower container 10 in the stacking state (see FIG. 8). Is abutted from the inside of the container body 10H where the receiving pocket 41 is not formed to prevent horizontal movement relative to the lower container 10 of the upper container 10.

  In the present embodiment, the positioning rib 61 is disposed directly below each of the stacked support protrusions 31. Specifically, like the extension rib 51, the positioning rib 61 extends downward from the protrusion-forming vertical rib 32 that constitutes the stacked support protrusion 31. In addition, in the long side part of the container main body 10H, the positioning rib 61 is extended from the downward direction of each of a pair of protrusion structure vertical ribs 32 and 32 which comprise the stacking support protrusion 31. As shown in FIG. In the short side portion of the container main body 10H, the pocket bottom wall overlapping portion described above from below one of the pair of projecting portion vertical ribs 32, 32 constituting the stacked support projecting portion 31. 50 is extended, and the positioning rib 61 is extended below the other protrusion structure vertical rib 32.

  As shown in FIG. 5, the end portion of the positioning rib 61 on the side close to the outer surface of the container body 10H is thicker than the portion located away from the outer surface of the container body 10H with respect to the end portion. The thick portion 62 is formed. In the example of this embodiment, the positioning rib 61 is formed in a triangular or trapezoidal shape that becomes thicker as it approaches the outer surface of the container body 10H.

  FIG. 12 shows a container 10S having a lower height than the container 10 shown in FIG. The basic configuration of the container 10S is the same as that of the container 10, and the height of the flange portion 21 is mainly different between the container 10S and the container 10. Specifically, in the flange portion 21 of the container 10S, the distance between the second intermediate overhanging wall 24B and the third intermediate overhanging wall 24C is narrower than that of the flange portion 21 of the container 10. Although the container 10S shown in FIG. 12 does not include the pocket bottom wall overlapping portion 50, the pocket bottom wall overlapping portion 50 may be included similarly to the container 10.

  The container 10 shown in FIG. 1 can be stacked on both the stacking state and the nesting state on the container 10S shown in FIG. Even when the containers 10 are stacked in a stacking state on the container 10S, the pocket bottom wall overlapping portion 50 of the upper container 10 is received in the receiving pocket 41 of the lower container 10S. Accordingly, it is possible to make the stacking support protrusion 31 come into contact with the upper surface of the flange portion of the lower container 10S without making the pocket bottom wall overlapping part 50 of the upper container 10 contact, and the container in the stacking state 10 stacks can be stabilized.

  When the containers 10 are stacked in a nesting state on the container 10S, the stacked support protrusions 31 of the upper container 10 are received in the receiving pockets 41 of the lower container 10S as shown in FIG. The Here, since the depth of the receiving pocket 41 of the lower container 10S is smaller than the height of the stacking support protrusion 31 of the upper container 10, the pocket bottom wall overlapping portion of the upper container 10 is provided. 50 (extension rib 51) is abutted against the bottom wall 41S of the receiving pocket 41, and the flange portion 21 of the upper container 10 is lifted from the flange portion 21 of the lower container 10S. In the example shown in FIG. 13, a part of the positioning rib 61 is accommodated in the receiving pocket 41 and comes into contact with the bottom wall 41 </ b> S. However, the positioning rib 61 is entirely in the container body 10 </ b> H than the receiving pocket 41. The structure which is arrange | positioned inside and does not contact | abut the bottom wall 41S may be sufficient. In this case, even if the pocket bottom wall overlapping portion 50 (extension rib 51) is formed shorter in the vertical direction than the positioning rib 61, the lower end of the pocket bottom wall overlapping portion 50 is disposed above the lower end of the positioning rib 61. Good.

  Here, in the container 10 of the present embodiment, the amount of protrusion of the pocket bottom wall overlapping portion 50 (extension rib 51) from the outer surface of the container body 10H is substantially the same as the depth of the receiving pocket 41, and When the container 10 receives a load from above, the upper container 10 is restricted from being fitted inside the lower container 10S. Thus, in this embodiment, when the container 10 is stacked in a nesting state on the container 10S having a low height, the pocket bottom wall overlapping portion 50 (extension rib 51) of the upper container 10 is on the lower stage side. By being abutted against the bottom wall 41S of the receiving pocket 41 of the container 10S from above, the fitting of the upper container 10 into the lower container 10S is suppressed.

  Moreover, when the containers 10 are stacked in a stacking state, the pocket bottom wall overlapping portion 50 of the upper container 10 is received in the receiving pocket 41 of the lower container 10 (see FIG. 10). In the stacking state, the stacking support protrusion 31 can be brought into contact with the upper surface of the flange portion 21 of the lower container 10 without contacting the pocket bottom wall overlapping portion 50 of the upper container 10. The stacking of the containers 10 in the state is stabilized. In addition, since the receiving pocket 41 that receives the pocket bottom wall overlapping portion 50 receives the stacked support protrusion 31 in the nesting state, it is not necessary to newly provide a pocket for receiving the pocket bottom wall overlapping portion 50.

  In the present embodiment, the stacking support protrusion 31 is provided with a protrusion-forming vertical rib 32 that protrudes from the outer surface of the container body 10H and extends in the vertical direction, and the pocket bottom wall overlapping portion 50 is In addition, since the projecting portion is constituted by the extension rib 51 formed by extending the vertical rib 32 downward, the strength of the pocket bottom wall overlapping portion 50 can be increased.

Even in such a configuration, when the container 10 is stacked on the container 10S in a nesting state, the pocket bottom wall overlapping portion 50 (extension rib 51) of the container 10 is the bottom wall 41S of the receiving pocket 41 of the container 10S. It is possible to suppress the bottom portion of the container 10 from fitting into the container 10S.

  (4) In the above embodiment, when the plurality of containers 10 are stacked, the upper container 10 is in the stacking state when the upper container 10 is oriented in the same direction as the lower container 10, and the upper container 10 is the lower container. The container 10 is configured so as to be in a nesting state in a direction opposite to the direction 10 (a state rotated 180 degrees in plan view), but the nesting is performed when the upper side container 10 is in the same direction as the lower side container 10. The upper container 10 may be in a stacking state when the upper container 10 is opposite to the lower container 10.

  (5) In the said embodiment, the pocket bottom wall overlap part 50 may be formed only in the long side part of the container main body 10H, and as shown in FIG. 14, it forms in both a short side part and a long side part. May be. In the example of FIG. 14, the pocket bottom wall overlapping portion 50 that protrudes from the first long side wall 13 </ b> A is formed in each of the pair of stacked support protrusions 31, 31 provided on the first long side wall 14 </ b> A. The long side wall 14 </ b> A is disposed directly below the end on one side in the width direction. Further, with respect to the pocket bottom wall overlapping portion 50 protruding from the second long side wall 13B, each of the pair of stacked support protrusions 31 and 31 provided on the second long side wall 13B has a second long side wall. It is arranged directly below the end on one side in the width direction of 13B. By arranging the pocket bottom wall overlapping portion 50 on the first long side wall 13A and the second long side wall 13B as described above, when the container 10 is stacked in a stacking state, the long side portion of the container main body 10H. The pocket bottom wall overlapping portion 50 formed in the above is also received in the receiving pocket 41 of the lower container 10 (see FIGS. 15A and 15B).

  (6) In the above-described embodiment, the flange portion 21 may be configured only by the upper end overhanging wall 22. Moreover, in the said embodiment, the intermediate | middle overhang | projection wall 24 which comprises the flange part 21 may be one.

  (7) In the above embodiment, in the stacking state, the stacking support protrusion 31 of the upper container 10 contacts the upper surface of the flange portion 21 of the lower container 10. A concave portion or a groove is formed on the upper surface of the flange portion 21, and the stacking support protrusion 31 of the upper container 10 is in contact with the bottom surface of the concave portion or groove formed on the flange portion 21 of the lower container 10. There may be.
