以下、図１～図９を参照して、本開示に係る嵩上部材付き容器１０の実施形態について説明する。嵩上部材付き容器１０は、箱形容器１１とその上面四隅に装着される４つの嵩上部材４０とからなる。また、箱形容器１１は、縦横の両方向で線対称な構造をなし、これに対応して、４つの嵩上部材４０は、互いに左右対称が関係を有する２種類の嵩上部材４０からなる。 Hereinafter, embodiments of a container 10 with a bulking member according to the present disclosure will be described with reference to FIGS. 1 to 9. FIG. The bulk member-equipped container 10 is composed of a box-shaped container 11 and four bulk members 40 attached to the four corners of its upper surface. Further, the box-shaped container 11 has a line-symmetrical structure in both the vertical and horizontal directions, and correspondingly, the four bulking members 40 are composed of two types of bulking members 40 having a bilaterally symmetrical relationship.

具体的には、図１に示すように、箱形容器１１は、例えば、平面形状が横長の長方形をなし、縦横に対して高さが低い扁平形状をなし、上面全体が開放している。また、箱形容器１１の縦横の側壁１２，１３は、底壁１４から略垂直に起立し（詳細には、底壁１４なら斜め上外側に向かうように起立し）、側壁１２，１３の上端からは上端フランジ１７（特許請求の範囲の「フランジ」に相当する）が側方に張り出すと共に下端からは下端フランジ１４Ｆが側方に張り出している。さらに、上端フランジ１７と下端フランジ１４Ｆとの間は、複数の縦リブ１８によって連絡されている。それら複数の縦リブ１８は、上下方向に延びかつ側壁１２，１３と直交している。なお、上端フランジ１７、下端フランジ１４Ｆ及び縦リブ１８の各先端面は、面一になって連続している。 Specifically, as shown in FIG. 1, the box-shaped container 11 has, for example, a horizontally long rectangular plane shape, a flat shape with a low height relative to the height and width, and an open top surface. The vertical and horizontal side walls 12, 13 of the box-shaped container 11 stand substantially vertically from the bottom wall 14 (more specifically, the bottom wall 14 stands obliquely upward and outward), and the upper ends of the side walls 12, 13 An upper end flange 17 (corresponding to a "flange" in claims) protrudes laterally from the lower end, and a lower end flange 14F laterally protrudes from the lower end. Further, a plurality of vertical ribs 18 communicate between the upper end flange 17 and the lower end flange 14F. The plurality of longitudinal ribs 18 extend vertically and are perpendicular to the side walls 12 and 13 . Note that the tip end surfaces of the upper end flange 17, the lower end flange 14F, and the longitudinal rib 18 are flush and continuous.

以下、側壁１２，１３を区別するときには、側壁１２を「短側壁１２」というと共に、側壁１３を「長側壁１３」ということとし、区別しないときには、単に「側壁１２，１３」ということとする。 Hereinafter, when distinguishing between the side walls 12 and 13, the side wall 12 will be referred to as the "short side wall 12" and the side wall 13 will be referred to as the "long side wall 13".

各短側壁１２の横方向の中央には、持手部１９が設けられている。持手部１９は、１対の縦リブ１８の先端縁の上部間に帯板１９Ｗを差し渡しかつ、帯板１９Ｗの上縁部を上端フランジ１７の先端縁に接続した構造をなしている。 A handle portion 19 is provided in the lateral center of each short side wall 12 . The handle portion 19 has a structure in which a strip plate 19W is laid between the tops of the tip edges of the pair of vertical ribs 18 and the upper edge of the strip plate 19W is connected to the tip edge of the upper end flange 17 .

底壁１４の下面からは、図２に示す下面突部１５が突出している。下面突部１５は、リブを格子状に交差させてなり、下面突部１５全体は、側壁１２，１３の真下位置より僅か内側に位置している。これにより、箱形容器１１同士を段積みした際には、上段側の箱形容器１１の下面突部１５が、下段側の箱形容器１１の上面開口１１Ｋ（図１参照）内に嵌合し、箱形容器１１同士の横ずれが防がれる。また、前述の下端フランジ１４Ｆは、底壁１４を外側に延長してなる。そして、箱形容器１１同士を段積みした際に、上段側の箱形容器１１の下端フランジ１４Ｆが下段側の箱形容器１１の上端フランジ１７に重なる。 A bottom projection 15 shown in FIG. 2 protrudes from the bottom surface of the bottom wall 14 . The bottom surface protrusion 15 is formed by intersecting ribs in a grid pattern, and the entire bottom surface protrusion 15 is located slightly inside the positions directly below the side walls 12 and 13 . As a result, when the box-shaped containers 11 are stacked together, the projection 15 on the lower surface of the box-shaped container 11 on the upper side fits into the opening 11K (see FIG. 1) on the upper surface of the box-shaped container 11 on the lower side. As a result, the box-shaped containers 11 are prevented from slipping sideways. Further, the lower end flange 14F described above extends the bottom wall 14 outward. When the box-shaped containers 11 are stacked together, the lower end flange 14F of the upper box-shaped container 11 overlaps the upper end flange 17 of the lower box-shaped container 11 .

図１に示すように、箱形容器１１の内側には、仕切部２０が備えられている。仕切部２０は、１対の短側壁１２の間を複数等分（例えば、３等分）する複数（例えば、２つ）の土手部２０Ｂと、１対の長側壁１３の間を複数等分（例えば、４等分）する複数（例えば、３つ）の土手部２０Ａとを一体に備えてなる。それら土手部２０Ａ，２０Ｂは、下面が開放した溝形構造をなし、その断面形状は左右対称の台形状になっている。また、土手部２０Ａ，２０Ｂの上面は互いに面一になっていて、箱形容器１１内の上下方向の略中央に位置している。さらに、土手部２０Ａ，２０Ｂの各上面には、それらの長手方向に沿って複数の矩形の貫通孔２０Ｃが等間隔に並んでいる。 As shown in FIG. 1, a partition 20 is provided inside the box-shaped container 11 . The partitioning portion 20 includes a plurality of (for example, two) embankment portions 20B that divide a pair of short side walls 12 into a plurality of equal parts (for example, into three equal parts), and a pair of long side walls 13 that divide into a plurality of equal parts. It is integrally provided with a plurality of (for example, three) bank portions 20A that are (for example, divided into four equal parts). The bank portions 20A and 20B have a grooved structure with an open bottom surface, and the cross-sectional shape thereof is a symmetrical trapezoidal shape. Moreover, the upper surfaces of the bank portions 20A and 20B are flush with each other, and are positioned substantially in the center of the box-shaped container 11 in the vertical direction. Further, a plurality of rectangular through-holes 20C are arranged at equal intervals along the longitudinal direction of the upper surfaces of the bank portions 20A and 20B.

なお、図５に示すように、底壁１４のうち仕切部２０と対向する部分は開口している。また、図２に示すように、底壁１４のうち仕切部２０と対向しない部分には、下面突部１５の格子状のリブの各目となる部分に、貫通孔１４Ａが形成されている。 In addition, as shown in FIG. 5, the part of the bottom wall 14 facing the partition part 20 is open. Further, as shown in FIG. 2, through holes 14A are formed in the portions of the bottom wall 14 that do not face the partitions 20, at the portions of the grid-like ribs of the lower projection 15. As shown in FIG.

On the other hand, the inner hanging piece 43 of the first linear portion 41 has the same width as the inner hanging piece 44 from the corner to the inner hanging piece 44 to the opposite tip position, and extends in the longitudinal direction of the first linear portion 41 . extended. An extended portion 49 protrudes downward from the end of the inner hanging piece 43 on the side away from the inner hanging piece 44 . The side edge portion of the extended portion 49 facing the inner hanging piece 44 side is curved in an S shape, and the horizontal lower edge portion of the extended portion 49 and the inner hanging piece 43 on the inner hanging piece 44 side of the expanded portion 49 are curved. It continues smoothly with the horizontal bottom edge.

外側垂下片４５は、一定の上下幅をなして第１直線部４１の長手方向の略全体に亘って延びている。また、外側垂下片４５の上下幅は、内側垂下片４４の上下幅より小さい。さらには、内側垂下片４３と外側垂下片４５との対向面間の距離は、短側壁１２上の上端フランジ１７が丁度収まる大きさをなしている。 The outer hanging piece 45 extends over substantially the entire length of the first linear portion 41 with a constant vertical width. Also, the vertical width of the outer hanging piece 45 is smaller than the vertical width of the inner hanging piece 44 . Furthermore, the distance between the facing surfaces of the inner hanging piece 43 and the outer hanging piece 45 is just large enough to accommodate the upper end flange 17 on the short side wall 12 .

内側垂下片４３及び外側垂下片４５の互いの対向面には、スライド係合突部４６，４７と係止突部４８が設けられている。一方のスライド係合突部４６は、拡張部４９の下端部から水平に突出するブロック構造をなしている。そして、箱形容器１１の上面に嵩上本体部５１の下面が重なったところで、箱形容器１１の前述したガイド凹部２８にスライド係合突部４６がスライド可能に係合する。 Slide engaging protrusions 46 and 47 and a locking protrusion 48 are provided on the mutually facing surfaces of the inner hanging piece 43 and the outer hanging piece 45 .

Then, when the lower surface of the bulky main body portion 51 overlaps the upper surface of the box-shaped container 11 , the sliding engagement protrusion 46 is slidably engaged with the aforementioned guide recess 28 of the box-shaped container 11 .

他方のスライド係合突部４７は、外側垂下片４５の長手方向のうち拡張部４９に近い側の端部における上下方向の中間位置に配置されている。また、スライド係合突部４７は、断面台形をなし、斜め下方を向いた傾斜面４７Ａと、水平になって上方を向いた係止面４７Ｂとを有する。そして、箱形容器１１にの上面に嵩上本体部５１の下面が重なったところで、スライド係合突部４７の係止面４７Ｂが上端フランジ１７の下面に重なる。また、図８（Ａ）に示すように、外側垂下片４５の長手方向におけるスライド係合突部４７の大きさは、同方向における箱形容器１１の第１凹部２３の開口幅より僅かに小さくなっている。そして、図７（Ａ）及び図８（Ａ）に示すように、スライド係合突部４６がガイド凹部２８のうち長側壁１３から離れた端部に配置されるとスライド係合突部４７が第１凹部２３と対向し、図６に示すように、スライド係合突部４７の係止面４７Ｂと上端フランジ１７の下面との上下方向における重なり量が僅かになる。これにより、外側垂下片４５を僅かに外側に弾性変形させて、嵩上部材４０を箱形容器１１に着脱することができる。以下、このときの嵩上部材４０の位置を「仮装着位置」という。 The other slide engaging protrusion 47 is arranged at a vertically intermediate position at the end of the outer hanging piece 45 on the side closer to the extended portion 49 in the longitudinal direction. The slide engaging protrusion 47 has a trapezoidal cross-section, and has an inclined surface 47A directed obliquely downward and a locking surface 47B horizontal and directed upward. Then, when the lower surface of the bulky body portion 51 overlaps the upper surface of the box-shaped container 11 , the locking surface 47B of the slide engaging protrusion 47 overlaps the lower surface of the upper end flange 17 . Also, as shown in FIG. 8A, the size of the sliding engagement protrusion 47 in the longitudinal direction of the outer hanging piece 45 is slightly smaller than the opening width of the first recess 23 of the box-shaped container 11 in the same direction. It's becoming Then, as shown in FIGS. 7A and 8A, when the slide engagement projection 46 is arranged at the end of the guide recess 28 away from the long side wall 13, the slide engagement projection 47 Facing the first recess 23, as shown in FIG. 6, the amount of vertical overlap between the locking surface 47B of the slide engaging protrusion 47 and the lower surface of the upper end flange 17 is small. As a result, the outer hanging piece 45 is elastically deformed slightly outward, and the bulk member 40 can be attached to and detached from the box-shaped container 11 . Hereinafter, the position of the bulk member 40 at this time will be referred to as a "temporary mounting position".

As a result, the cargo in the box-shaped container 11 abuts against the bulk member 40 and the bulk member 40 is prevented from unintentionally coming off from the box-shaped container 11 . 40 is stable.

また、本実施形態の構成では、嵩上部材４０が本装着位置に配置されると、嵩上部材４０の係止突部４８，６１が、箱形容器１１に係止するので、嵩上部材４０が箱形容器１１から外れる方向へのスライドが防がれる。しかも、図９に示すように、嵩上部材４０の第１直線部４１の外側面と第２直線部４２との外側面とが共に、箱形容器１１の上端フランジ１７の先端面より内側に位置するので、異物が嵩上部材４０に引っ掛かり難くなり、このことによっても、嵩上部材４０が意図せず外れる不具合の発生が抑えられる。 In addition, in the configuration of the present embodiment, when the bulk member 40 is arranged at the fully installed position, the locking protrusions 48 and 61 of the bulk member 40 lock onto the box-shaped container 11, so that the bulk member 40 is prevented from sliding in a direction away from the box-shaped container 11.例文帳に追加Moreover, as shown in FIG. 9, both the outer surface of the first straight portion 41 and the outer surface of the second straight portion 42 of the bulking member 40 are located inside the tip surface of the upper end flange 17 of the box-shaped container 11. Because of the position, it becomes difficult for foreign matter to get caught on the bulking member 40, and this also suppresses the problem of the bulking member 40 coming off unintentionally.

また、本実施形態では、嵩上部材４０の第１直線部４１における外側垂下片４５の下端部が、内側垂下片４３の下端部より上方に位置している。これにより、図５に示すように、嵩上部材４０を第１直線部４１のうち外側垂下片４５が配置されている外縁側を下げた傾斜姿勢にして、外側垂下片４５のスライド係合突部４７を箱形容器１１の外側面（詳細には、上端フランジ１７の先端部の下面）に容易に係合させることができる。そして、図６に示すように、嵩上部材４０を水平姿勢にすれば、内側垂下片４３のスライド係合突部４６が箱形容器１１の内側面（詳細には、箱形容器１１のガイド凹部２８）に容易に係合する。このように本実施形態の構成によれば、嵩上部材４０の箱形容器１１に対する組み付けを容易に行うことができる。 Further, in the present embodiment, the lower end of the outer hanging piece 45 in the first linear portion 41 of the bulking member 40 is located above the lower end of the inner hanging piece 43 . As a result, as shown in FIG. 5, the bulking member 40 is placed in an inclined posture in which the outer edge side of the first linear portion 41 where the outer hanging piece 45 is arranged is lowered, and the sliding engagement projection of the outer hanging piece 45 is engaged. The portion 47 can be easily engaged with the outer surface of the box-shaped container 11 (specifically, the lower surface of the tip of the upper end flange 17). Then, as shown in FIG. 6, when the bulk member 40 is placed in a horizontal position, the sliding engagement protrusion 46 of the inner hanging piece 43 is positioned on the inner surface of the box-shaped container 11 (specifically, the guide of the box-shaped container 11). It easily engages the recess 28). Thus, according to the configuration of this embodiment, the bulk member 40 can be easily assembled to the box-shaped container 11 .

さらに、嵩上部材４０が本装着位置に配置されると、図７（Ｂ）に示すように、第２直線部４２の内側垂下片４３から突出する１対の嵌合突部６０が、箱形容器１１の１対の嵌合孔２９に嵌合することで、嵩上部材４０の上方へのズレが抑えられる。また、嵩上部材付き容器１０同士を段積みすると、下段側の嵩上部材付き容器１０の４つの嵩上部材４０の内側に上段側の下面突部１５（図２参照）が嵌合して嵩上部材付き容器１０同士の横ずれが防がれる。また、図７（Ｂ）に示すように、嵩上部材４０の補強リブ５６Ａ，５６Ｂ，５６Ｃが、箱形容器１１のコーナー及びその近傍の縦リブ１８Ａ，１８Ｂ，１８Ｃの真上にそれぞれ配置されるので、上段側の箱形容器１１の荷重による箱形容器１１の変形が抑えられ、段積み姿勢が安定する。 Furthermore, when the bulking member 40 is arranged at the fully installed position, as shown in FIG. By fitting into the pair of fitting holes 29 of the shaped container 11, upward displacement of the bulking member 40 is suppressed. Further, when the containers 10 with bulk members are stacked together, the lower projections 15 (see FIG. 2) on the upper side are fitted inside the four bulk members 40 of the container 10 with bulk members on the lower side. Lateral slippage between the containers 10 with bulking members is prevented. Further, as shown in FIG. 7B, the reinforcing ribs 56A, 56B, 56C of the bulking member 40 are arranged directly above the corners of the box-shaped container 11 and the vertical ribs 18A, 18B, 18C in the vicinity thereof, respectively. Therefore, deformation of the box-shaped containers 11 due to the load of the box-shaped containers 11 on the upper side is suppressed, and the stacking posture is stabilized.

なお、嵩上部材付き容器１０は、箱形容器１１単独で使用することもできる。この場合、箱形容器１１同士を上下に段積みすると、下段側の箱形容器１１の上面開口１１Ｋ（図１参照）に上段側の下面突部１５（図２参照）が嵌合して箱形容器１１同士の横ずれが防がれる。 The box-shaped container 11 can also be used alone as the container 10 with the bulk member. In this case, when the box-shaped containers 11 are stacked vertically, the upper projections 15 (see FIG. 2) on the upper side fit into the upper openings 11K (see FIG. 1) of the box-shaped containers 11 on the lower side to form the box. Lateral slippage between the shaped containers 11 is prevented.
