Placed in position. When the lid member is put on the folded container body, the outer peripheral wall portion of the lid member is arranged on the outer surface side of the base side locking portion and above the upper side portion of the base portion. NS. As a result, it is possible to prevent the lid member covered with the container body from being displaced relative to each other in the horizontal direction and falling off, and to prevent the lid member from protruding outward from the outer peripheral surface of the container body. ..

さらに、側壁側係止部は、補強リブ構造を備え、土台側係止部は、補強リブ構造からなる補強構造、及び、２重壁構造からなる補強構造のうち少なくとも一方の補強構造を具備している。このため、側壁側係止部、及び、土台側係止部の強度を飛躍的に高めることができる。従って、側壁部、及び、土台部の上端部の変形や損傷を防止することができ、蓋付き容器の耐久性の向上、及び、蓋部材を容器本体に被せた状態の安定化等を図ることができる。 Further, the side wall side fastening part is provided with a reinforcing rib structure, foundation side latching section, the reinforcing structure consisting of reinforcing rib structure, and comprises at least one reinforcing structure of the reinforcing structure consisting of a double wall structure ing. Therefore, the strength of the side wall side locking portion and the base side locking portion can be dramatically increased. Therefore, it is possible to prevent deformation and damage of the side wall portion and the upper end portion of the base portion, improve the durability of the container with a lid, and stabilize the state in which the lid member is covered with the container body. Can be done.

尚、「前記土台側係止部は、前記第１係止縦壁、前記第２係止縦壁、及び、前記上係止連結壁の間を連結し、上下に延在する中連結リブを備えること」としてもよい。この場合、２重壁構造の強度等をより一層高めることができる。また、「前記側壁側係止部の前記側壁側係止縦壁は、前記側壁部の内面を構成するベース壁部を上方に延長させるようにして設けられ、前記側壁側係止上壁は前記側壁側係止縦壁の上辺部から外方に突出すること」としてもよい。さらに、「前記土台側係止部の前記土台側係止縦壁、及び、前記第１係止縦壁は、前記土台部の内面を構成する前記内壁部を上方に延長させるようにして設けられ、前記土台側係止上壁、及び、前記上係止連結壁は、前記土台側係止縦壁の上辺部から外方に突出すること」としてもよい。これらの構成を採用する場合、側壁側係止部、及び、土台側係止部に対して下向きの力が付加された場合に、底壁側係止部、及び、土台側係止部をより安定して支持することができる。さらに、補強リブ構造が側壁部、及び、土台部の外面側に設けられることとなり、容器本体に収容された物品を取出す際に物品が補強リブ構造に引っ掛かる等といった事態を回避することができる。 It should be noted that "the base-side locking portion connects between the first locking vertical wall, the second locking vertical wall, and the upper locking connecting wall, and has an intermediate connecting rib extending vertically. It may be "to prepare". In this case, the strength of the double wall structure and the like can be further increased. Further, "the side wall side locking vertical wall of the side wall side locking portion is provided so as to extend the base wall portion constituting the inner surface of the side wall portion upward, and the side wall side locking upper wall is the said. It may be "protruding outward from the upper side of the side wall locking vertical wall". Further, "the base-side locking vertical wall of the base-side locking portion and the first locking vertical wall are provided so as to extend the inner wall portion constituting the inner surface of the base portion upward. The base-side locking upper wall and the upper locking connecting wall may project outward from the upper side of the base-side locking vertical wall. " When these configurations are adopted, when a downward force is applied to the side wall side locking portion and the base side locking portion, the bottom wall side locking portion and the base side locking portion are twisted. Can be stably supported. Further, the reinforcing rib structure is provided on the outer surface side of the side wall portion and the base portion, and it is possible to avoid a situation in which the article is caught in the reinforcing rib structure when the article contained in the container body is taken out.

また、「前記組立状態にある前記容器本体に前記蓋部材を被せた場合には、前記側壁側係止部の上面が、前記天壁部の下面に当接し、前記折畳み状態にある前記容器本体に前記蓋部材を被せた場合には、前記土台側係止部の上面が、前記天壁部の下面に当接すること」としてもよい。この場合、蓋部材を容器本体に被せた状態において、例えば、蓋部材の外周壁部が側壁部の上辺部や土台部の上辺部と当接し、天壁部が側壁側係止部や土台側係止部と当接しないような構成に比べ、蓋部材の外周壁部にかかる負担を軽減させることができる。従って、容器本体に被せられた蓋部材に対して下向きの力が付加された場合に外周壁部が変形、損傷してしまうといった事態を防止したり、或いは、かかる変形等を回避するべく、外周壁部を厚肉に構成することで、側壁側係止部や土台側係止部を薄くする必要が生じたり、蓋部材の製造効率の低下を招いたりするといった事態を回避することができる。 Further, "when the lid member is put on the container body in the assembled state, the upper surface of the side wall side locking portion abuts on the lower surface of the top wall portion, and the container body in the folded state. When the lid member is put on the surface, the upper surface of the base-side locking portion may come into contact with the lower surface of the top wall portion. " In this case, in the state where the lid member is put on the container body, for example, the outer peripheral wall portion of the lid member abuts on the upper side portion of the side wall portion or the upper side portion of the base portion, and the top wall portion is on the side wall side locking portion or the base side. The load on the outer peripheral wall portion of the lid member can be reduced as compared with the configuration in which the lid member does not come into contact with the locking portion. Therefore, in order to prevent a situation in which the outer peripheral wall portion is deformed or damaged when a downward force is applied to the lid member covered on the container body, or to avoid such deformation, the outer circumference By forming the wall portion thick, it is possible to avoid a situation in which the side wall side locking portion and the base side locking portion need to be thinned, or the manufacturing efficiency of the lid member is lowered.

また、挿入部に対応する部位の土台側係止部を省略することにより、土台部の厚み方向における挿入部の幅を十分に確保することができ、ひいては、ヒンジ本体の厚みを十分に確保することができる。従って、ヒンジ部の耐久性の向上等を図ることができる。さらに、土台側係止部のうち軸支部に対応する部位の補強構造（補強リブ構造、又は、２重壁構造）が省略されることにより、土台部の厚み方向において軸支部の幅を確保し易くなり、ひいては、ヒンジ部の軸部の太さや、軸部が軸支部から上方に抜け出すことを防止するフック部の大きさ等を確保することができる。加えて、軸受部を比較的スムースに成型することができる。 Further, by omitting the base-side locking portion of the portion corresponding to the insertion portion, the width of the insertion portion in the thickness direction of the base portion can be sufficiently secured, and by extension, the thickness of the hinge body can be sufficiently secured. be able to. Therefore, the durability of the hinge portion can be improved. Further, the width of the shaft support portion is secured in the thickness direction of the base portion by omitting the reinforcing structure (reinforcing rib structure or double wall structure) of the portion of the base side locking portion corresponding to the shaft support portion. This makes it easier, and by extension, the thickness of the shaft portion of the hinge portion and the size of the hook portion that prevents the shaft portion from coming out of the shaft support portion can be secured. In addition, the bearing portion can be molded relatively smoothly.

尚、土台側係止部が土台部の長手方向において断続的に設けられる構成であっても、上記手段１に記載のように、土台側係止部は、補強リブ構造からなる補強構造、及び、２重壁構造からなる補強構造のうち少なくとも一方を備えることから、断続的に設けられた土台側係止部毎に強度を確保することができる。 Even if the base side locking portion is provided intermittently in the longitudinal direction of the base portion, as described in the above means 1, the base side locking portion has a reinforcing structure composed of a reinforcing rib structure and a reinforcing structure . Since at least one of the reinforcing structures having the double wall structure is provided, the strength can be ensured for each of the base-side locking portions provided intermittently.

手段２．前記側壁側係止部が設けられた前記側壁部は、前記起立位置とされた場合に、前記土台側係止部の上面と外側面とのなす角部に当接可能に構成され、前記底壁部の内周側に向けて上方傾斜する起立傾斜部を備えていることを特徴とする手段１に記載の蓋付き容器。 Means 2 . The side wall portion provided with the side wall side locking portion is configured to be able to come into contact with the corner portion formed by the upper surface and the outer surface of the base side locking portion when the side wall portion is in the upright position, and the bottom thereof. The container with a lid according to means 1, further comprising an upright inclined portion that inclines upward toward the inner peripheral side of the wall portion.

手段２によれば、側壁側係止部が設けられた側壁部を起立位置とした場合に、当該側壁部の起立傾斜部と、土台部の土台側係止部とが当接することで、当該側壁部の寝かせ位置側への傾倒変位が抑制されることとなる。従って、起立位置にある側壁部を自立させておくことができ、容器本体の組立て作業性の向上等を図ることができる。 According to the means 2 , when the side wall portion provided with the side wall side locking portion is set to the upright position, the upright inclined portion of the side wall portion and the base side locking portion of the base portion come into contact with each other. Tilt displacement of the side wall portion toward the laying position side is suppressed. Therefore, the side wall portion in the upright position can be made to stand on its own, and the workability of assembling the container body can be improved.

また、一般に、容器本体は、容器本体同士を積み重ねる（段積みする）ことができるように構成されており、組立状態にある容器本体を段積みした場合には、上側の容器本体の底壁構成部のうち外周側の部位（以下、「外周対応部」と称する）が、下側の容器本体の側壁部の上辺部に当接して支持されるようになっている。さらに、底壁部は、外周対応部よりも内周側の部位から下方に突出する支持部を備え、組立状態にある容器本体を段積みした場合には、上側の容器本体の支持部が、下側の容器本体の側壁部の内周側に挿入される（略嵌合する）ように構成されている。当該構成により、容器本体を平らな設置面に設置した場合、底壁構成部のうち、土台部の下方位置でもある外周対応部は、設置面から離間して直接的に支持されない構成となっている。このため、土台部には、極力外側に開くような力が加えられないようにすることが望ましい。 Further, in general, the container body is configured so that the container bodies can be stacked (stacked) with each other, and when the container bodies in the assembled state are stacked, the bottom wall configuration of the upper container body is configured. Of the portions, the outer peripheral side portion (hereinafter, referred to as “outer peripheral corresponding portion”) is supported by abutting on the upper side portion of the side wall portion of the lower container body. Further, the bottom wall portion is provided with a support portion that protrudes downward from a portion on the inner peripheral side of the outer peripheral corresponding portion, and when the container bodies in the assembled state are stacked, the support portion of the upper container body is formed. It is configured to be inserted (substantially fitted) into the inner peripheral side of the side wall portion of the lower container body. With this configuration, when the container body is installed on a flat installation surface, the outer peripheral corresponding portion, which is also the lower position of the base portion, is separated from the installation surface and is not directly supported. There is. For this reason, it is desirable that the base portion is not subjected to a force that opens outward as much as possible.

この点、本手段２によれば、容器本体が組立状態にある場合に、側壁側係止部が設けられた側壁部に対して下方に向かう力が付加された場合には、当該側壁部の起立傾斜部と、土台部の土台側係止部とが圧接し、土台側係止部には、内側（底壁部の内周側）に傾倒変位させられるような力が付加される。従って、土台部が外側に傾倒変位するといった事態を防止することができる。 In this regard, according to the present means 2 , when the container body is in the assembled state and a downward force is applied to the side wall portion provided with the side wall side locking portion, the side wall portion is subjected to a downward force. The upright inclined portion and the base side locking portion of the base portion are in pressure contact with each other, and a force is applied to the base side locking portion so as to be tilted and displaced inward (inner peripheral side of the bottom wall portion). Therefore, it is possible to prevent a situation in which the base portion is tilted and displaced outward.

尚、起立位置にある側壁部の起立傾斜部から土台側係止部に対して底壁部の内周側に力が加えられる構成であっても、上記手段１に記載のように、土台側係止部は、補強リブ構造からなる補強構造、及び、２重壁構造からなる補強構造のうち少なくとも一方を備えることから、土台側係止部の変形や損傷等を防止することができる。 Even if a force is applied from the upright inclined portion of the side wall portion in the upright position to the inner peripheral side of the bottom wall portion with respect to the base side locking portion, as described in the above means 1, the base side Since the locking portion includes at least one of a reinforcing structure having a reinforcing rib structure and a reinforcing structure having a double wall structure, it is possible to prevent deformation and damage of the base side locking portion.

The wall 63 projects outward from the upper side of the side wall locking vertical wall 62. Further, the base-side locking vertical wall 75 of the base-side locking portion 71 is provided so as to extend the inner wall portion 74 constituting the inner surface of the long-side side base portion 13 upward, and the base-side locking upper wall 76 is provided. Projects outward from the upper side of the base-side locking vertical wall 75. With these configurations, when a downward force is applied to the side wall side locking portion 61 and the base side locking portion 71, the bottom wall side locking portion 68 and the base side locking portion 71 are formed. It can be supported more stably. Further, the reinforcing rib structure is provided on the outer surface side of the long side side wall portion 15 and the long side side base portion 13, and the article is caught by the reinforcing rib structure when the article housed in the container body 3 is taken out. Such a situation can be avoided.

また、組立状態にある容器本体３に蓋部材４を被せた場合には、側壁側係止部６１の上面が、天壁部４５の下面に当接し、折畳み状態にある容器本体３に蓋部材４を被せた場合には、土台側係止部７１の上面が、天壁部４５の下面に当接する。このため、蓋部材４を容器本体３に被せた状態において、例えば、蓋部材４の外周壁部４６が長辺側側壁部１５の上辺部や長辺側土台部１３の上辺部と当接し、天壁部４５が側壁側係止部６１や土台側係止部７１と当接しないような構成に比べ、蓋部材４の外周壁部４６にかかる負担を軽減させることができる。従って、容器本体３に被せられた蓋部材４に対して下向きの力が付加された場合に外周壁部４６が変形、損傷してしまうといった事態を防止したり、或いは、かかる変形等を回避するべく、外周壁部４６を厚肉に構成することで（型成型品とすることで）、側壁側係止部６１や土台側係止部７１を薄くする必要が生じたり、蓋部材４の製造効率の低下を招いたりするといった事態を回避することができる。 Further, when the lid member 4 is put on the container body 3 in the assembled state, the upper surface of the side wall side locking portion 61 abuts on the lower surface of the top wall portion 45, and the lid member 3 is in the folded state. When 4 is covered, the upper surface of the base-side locking portion 71 comes into contact with the lower surface of the top wall portion 45. Therefore, in a state where the lid member 4 is covered with the container body 3, for example, the outer peripheral wall portion 46 of the lid member 4 comes into contact with the upper side portion of the long side side wall portion 15 and the upper side portion of the long side side base portion 13. Compared with a configuration in which the top wall portion 45 does not come into contact with the side wall side locking portion 61 or the base side locking portion 71, the load on the outer peripheral wall portion 46 of the lid member 4 can be reduced. Therefore, it is possible to prevent the outer peripheral wall portion 46 from being deformed or damaged when a downward force is applied to the lid member 4 placed on the container body 3, or to avoid such deformation. Therefore, by making the outer peripheral wall portion 46 thick (by making it a molded product), it becomes necessary to make the side wall side locking portion 61 and the base side locking portion 71 thinner, or the lid member 4 is manufactured. It is possible to avoid a situation that causes a decrease in efficiency.

また、本実施形態では、長辺側土台部１３の長手方向において、長辺側軸受部１７の挿入部３１に対応する部位の土台側係止部７１が省略されている。このため、例えば、挿入部３１に対応する部位にも長辺側土台部１３の上辺部に対して土台側係止部７１を設けるような構成に比べ、長辺側土台部１３の厚み方向における挿入部３１を十分に確保することができ、ひいては、ヒンジ本体２６の厚みを十分に確保することができる。従って、長辺側ヒンジ部２５の耐久性の向上等を図ることができる。 Further, in the present embodiment, in the longitudinal direction of the long side base portion 13, the base side locking portion 71 of the portion corresponding to the insertion portion 31 of the long side bearing portion 17 is omitted. Therefore, for example, in the thickness direction of the long side base portion 13, as compared with the configuration in which the base side locking portion 71 is provided with respect to the upper side portion of the long side base portion 13 also in the portion corresponding to the insertion portion 31. The insertion portion 31 can be sufficiently secured, and the thickness of the hinge main body 26 can be sufficiently secured. Therefore, the durability of the long side hinge portion 25 can be improved.

さらに、土台側係止部７１のうち、長辺側軸受部１７の軸支部３２に対応する部位の補強構造（補強リブ構造、又は、２重壁構造）が省略されている（土台側係止縦壁７５が存在するのみとなっている）。このため、長辺側土台部１３の厚み方向における軸支部３２の幅を確保し易くなり、ひいては、長辺側ヒンジ部２５の軸部２７の太さや、軸部２７が軸支部３２から上方に抜け出すことを防止するフック部３３の大きさ等を確保することができる。加えて、長辺側軸受部１７を比較的スムースに成型することができる。 Further, among the base side locking portions 71, the reinforcing structure (reinforcing rib structure or double wall structure) of the portion corresponding to the shaft support portion 32 of the long side bearing portion 17 is omitted (base side locking). There is only a vertical wall 75). Therefore, it becomes easy to secure the width of the shaft support portion 32 in the thickness direction of the long side base portion 13, and by extension, the thickness of the shaft portion 27 of the long side side hinge portion 25 and the shaft portion 27 move upward from the shaft support portion 32. It is possible to secure the size and the like of the hook portion 33 that prevents the hook portion 33 from coming off. In addition, the long side bearing portion 17 can be molded relatively smoothly.

尚、土台側係止部７１が長辺側土台部１３の長手方向において断続的に設けられる構成であっても、上記のように、土台側係止部７１は、補強リブ構造、及び、２重壁構造のうち少なくとも一方を備えることから、断続的に設けられた土台側係止部７１毎に強度を確保することができる。 Even if the base side locking portion 71 is provided intermittently in the longitudinal direction of the long side base portion 13, as described above, the base side locking portion 71 has a reinforcing rib structure and 2 Since at least one of the heavy wall structures is provided, the strength can be ensured for each of the base-side locking portions 71 provided intermittently.

また、長辺側側壁部１５の下フランジ部２３には、当該長辺側側壁部１５が起立位置とされた場合に、土台側係止部７１の上面と外側面とのなす角部に当接し、底壁部１２の内周側に向けて上方傾斜する起立傾斜部８３が設けられている。このため、折畳み状態にある容器本体３を組立状態とする際に、側壁側係止部６１が設けられた長辺側側壁部１５を起立位置とした場合に、当該長辺側側壁部１５の起立傾斜部８３と、長辺側土台部１３の土台側係止部７１とが当接することで、当該長辺側側壁部１５の寝かせ位置側への傾倒変位が抑制されることとなる。従って、起立位置にある長辺側側壁部１５を自立させておくことができ、容器本体３の組立て作業性の向上等を図ることができる。 Further, the lower flange portion 23 of the long side side wall portion 15 hits the corner portion formed by the upper surface and the outer surface of the base side locking portion 71 when the long side side wall portion 15 is in the upright position. An upright inclined portion 83 that is in contact with the bottom wall portion 12 and is inclined upward toward the inner peripheral side is provided. Therefore, when the container body 3 in the folded state is put into the assembled state, when the long side side wall portion 15 provided with the side wall side locking portion 61 is set to the upright position, the long side side side wall portion 15 When the upright inclined portion 83 and the base side locking portion 71 of the long side base portion 13 come into contact with each other, the tilt displacement of the long side side wall portion 15 toward the laying position side is suppressed. Therefore, the long side side wall portion 15 in the upright position can be made to stand on its own, and the assembling workability of the container body 3 can be improved.

さらに、容器本体３は、平らな設置面に設置された場合、底壁構成部１１のうち、長辺側土台部１３、及び、短辺側土台部１４の下方位置でもある外周対応部６６は、設置面から離間して直接的に支持されない構成となっている。このため、長辺側土台部１３、及び、短辺側土台部１４には、極力外側に開くような力が加えられないようにすることが望ましい。 Further, when the container body 3 is installed on a flat installation surface, among the bottom wall component 11, the outer peripheral corresponding portion 66, which is also a lower position of the long side base portion 13 and the short side base portion 14, , It is configured so that it is separated from the installation surface and is not directly supported. Therefore, it is desirable that the long side base portion 13 and the short side base portion 14 are not subjected to a force that opens outward as much as possible.

この点、本実施形態によれば、容器本体３が組立状態にある場合に、長辺側側壁部１５に対して下方に向かう力が付加された場合には、当該長辺側側壁部１５の起立傾斜部８３と、長辺側土台部１３の土台側係止部７１とが圧接し、土台側係止部７１には、内側（底壁部１２の内周側）に傾倒変位させられるような力が付加される。従って、長辺側土台部１３が外側に傾倒変位するといった事態を防止することができる。 In this regard, according to the present embodiment, when the container body 3 is in the assembled state and a downward force is applied to the long side side wall portion 15, the long side side side wall portion 15 The upright inclined portion 83 and the base side locking portion 71 of the long side base portion 13 are in pressure contact with each other, and the base side locking portion 71 is tilted and displaced inward (the inner peripheral side of the bottom wall portion 12). Power is added. Therefore, it is possible to prevent a situation in which the long side base portion 13 is tilted and displaced outward.

尚、起立位置にある長辺側側壁部１５の起立傾斜部８３から土台側係止部７１に対して底壁部１２の内周側に力が加えられる構成であっても、上記のように、土台側係止部７１は、補強リブ構造、及び、２重壁構造のうち少なくとも一方を備えることから、土台側係止部７１の変形や損傷等を防止することができる。 As described above, even if a force is applied from the standing inclined portion 83 of the long side side wall portion 15 in the standing position to the inner peripheral side of the bottom wall portion 12 with respect to the base side locking portion 71. Since the base side locking portion 71 includes at least one of a reinforcing rib structure and a double wall structure, deformation and damage of the base side locking portion 71 can be prevented.

また、本実施形態では、側壁側係止部６１、及び、土台側係止部７１のほぼ全体が補強構造を具備するように構成されており、特に、容器本体３をパレット５に載置した場合に、側柱部５１、及び、中央柱部５２の上方に位置する部位に関しては、比較的強度の高い補強構造（側壁側特定補強部９１、土台側特定補強部９３）とされている。つまり、パレット５に容器本体３を載置するとともに、当該容器本体３に対して蓋部材８８を被せた運搬ユニット１（図１６、図１７参照）を段積みする（下側の運搬ユニット１の蓋部材８８に対し、上側の運搬ユニット１のパレット５を載せる）場合に、側壁側係止部６１、及び、土台側係止部７１のうち、上側の運搬ユニット１からの荷重を受ける部位に対して、補強構造が効果的に設けられている。従って、側壁側係止部６１、及び、土台側係止部７１の変形や損傷等を防止するとともに、運搬ユニット１の段積み状態の安定化等を図ることができる。 Further, in the present embodiment, almost the entire side wall side locking portion 61 and the base side locking portion 71 are configured to have a reinforcing structure, and in particular, the container body 3 is placed on the pallet 5. In this case, the side pillar portion 51 and the portion located above the central pillar portion 52 have a relatively high-strength reinforcing structure (side wall side specific reinforcing portion 91, base side specific reinforcing portion 93). That is, the container body 3 is placed on the pallet 5, and the transport unit 1 (see FIGS. 16 and 17) in which the lid member 88 is covered with the container body 3 is stacked (see the lower transport unit 1). When the pallet 5 of the upper transport unit 1 is placed on the lid member 88), the portion of the side wall side locking portion 61 and the base side locking portion 71 that receives the load from the upper transport unit 1 On the other hand, the reinforcing structure is effectively provided. Therefore, it is possible to prevent deformation and damage of the side wall side locking portion 61 and the base side locking portion 71, and to stabilize the stacked state of the transport unit 1.

さらに、長辺側側壁部１５は、組立状態にある容器本体３をパレット５に載置した状態において少なくとも側柱部５１、及び、中央柱部５２の上方に位置する部位に、上フランジ部２２と下フランジ部２３との間を連結する側壁補強リブ２４を備えている。このため、側壁側係止部６１の補強構造と、土台側係止部７１の補強構造との間に側壁補強リブ２４が設けられることとなり、長辺側側壁部１５の変形等をより確実に防止することができる。従って、容器本体３が組立状態にある蓋付き容器２を含む運搬ユニット１の段積み状態の安定化等を図ることができる。 Further, the long side side wall portion 15 has an upper flange portion 22 at a portion located above at least the side pillar portion 51 and the central pillar portion 52 when the container body 3 in the assembled state is placed on the pallet 5. It is provided with a side wall reinforcing rib 24 that connects between the lower flange portion 23 and the lower flange portion 23. Therefore, the side wall reinforcing rib 24 is provided between the reinforcing structure of the side wall side locking portion 61 and the reinforcing structure of the base side locking portion 71, so that the deformation of the long side side wall portion 15 and the like can be more reliably performed. Can be prevented. Therefore, it is possible to stabilize the stacked state of the transport unit 1 including the container 2 with a lid in which the container body 3 is in the assembled state.

加えて、容器本体３をパレット５に載置した状態において、底壁構成部１１のうち、少なくとも側柱部５１、及び、中央柱部５２の上方に位置する部位には、傾斜壁９５、及び、厚底部９７が設けられており、底壁構成部１１の該当部位の強度が高められている。従って、運搬ユニット１の段積み状態の安定化を図るといった作用効果がより一層奏されることとなる。 In addition, in the state where the container body 3 is placed on the pallet 5, the inclined wall 95 and the inclined wall 95 and the portion located above at least the side pillar portion 51 and the central pillar portion 52 in the bottom wall component portion 11 , A thick bottom portion 97 is provided, and the strength of the corresponding portion of the bottom wall constituent portion 11 is increased. Therefore, the action and effect of stabilizing the stacked state of the transport unit 1 can be further achieved.

尚、上記実施形態の記載内容に限定されず、例えば次のように実施してもよい。勿論、以下において例示しない他の応用例、変更例も当然可能である。 The content is not limited to the description of the above embodiment, and may be implemented as follows, for example. Of course, other application examples and modification examples not illustrated below are also possible.

（ａ）上記実施形態では、側壁側係止部６１の側壁側係止縦壁６２、並びに、土台側係止部７１の土台側係止縦壁７５、及び、第１係止縦壁７８が、長辺側側壁部１５のベース壁部２１、並びに、長辺側土台部１３の内壁部７４を上方に延長させるようにして設けられているが、外方にずれた位置に設けられていてもよい。さらに、側壁側係止部６１の側壁側係止上壁６３が側壁側係止縦壁６２の上辺部から外方に突出し、土台側係止部７１の土台側係止上壁７６が土台側係止縦壁７５の上辺部から外方に突出しているが、側壁側係止上壁６３が、側壁側係止縦壁６２の上辺部から内方に突出し、土台側係止上壁７６が土台側係止縦壁７５の上辺部から内方に突出するように構成してもよい。 (A) In the above embodiment, the side wall side locking vertical wall 62 of the side wall side locking portion 61, the base side locking vertical wall 75 of the base side locking portion 71, and the first locking vertical wall 78 are formed. , The base wall portion 21 of the long side side wall portion 15 and the inner wall portion 74 of the long side base portion 13 are provided so as to extend upward, but are provided at positions shifted outward. May be good. Further, the side wall side locking upper wall 63 of the side wall side locking portion 61 projects outward from the upper side portion of the side wall side locking vertical wall 62, and the base side locking upper wall 76 of the base side locking portion 71 is on the base side. The side wall side locking upper wall 63 protrudes inward from the upper side portion of the side wall side locking vertical wall 62, and the base side locking upper wall 76 protrudes outward from the upper side portion of the locking vertical wall 75. It may be configured so as to project inward from the upper side of the base-side locking vertical wall 75.

但し、側壁側係止縦壁６２、並びに、土台側係止縦壁７５、及び、第１係止縦壁７８が、ベース壁部２１、並びに、内壁部７４の延長線上に設けられることにより、側壁側係止縦壁６２、並びに、土台側係止縦壁７５、及び、第１係止縦壁７８に下向きの力が掛けられた場合等において、側壁側係止縦壁６２、並びに、土台側係止縦壁７５、及び、第１係止縦壁７８をより効果的に支持することができる。さらに、上記実施形態のように、側壁側係止部６１及び土台側係止部７１の補強リブ構造を外面側に形成することで、容器本体３に収容された物品を取出す際等において、物品が補強リブ構造に引っ掛かる等の事態を回避することができる。 However, the side wall side locking vertical wall 62, the base side locking vertical wall 75, and the first locking vertical wall 78 are provided on the extension lines of the base wall portion 21 and the inner wall portion 74. When a downward force is applied to the side wall side locking vertical wall 62, the base side locking vertical wall 75, and the first locking vertical wall 78, etc., the side wall side locking vertical wall 62 and the base. The side locking vertical wall 75 and the first locking vertical wall 78 can be supported more effectively. Further, as in the above embodiment, by forming the reinforcing rib structure of the side wall side locking portion 61 and the base side locking portion 71 on the outer surface side, the article is taken out when the article contained in the container body 3 is taken out. Can be avoided from being caught in the reinforcing rib structure.

（ｂ）上記実施形態では、長辺側側壁部１５の横幅方向全体にわたり側壁側係止部６１が連続して設けられているが、長辺側側壁部１５の横幅方向全体にわたり側壁側係止部６１が断続的に設けられることとしてもよい。但し、容器本体３に被せた蓋部材４の外周壁部４６を容器本体３の長辺側側壁部１５の外面から外方に突出しないようにするべく、長辺側側壁部１５の上辺部のうち長辺側側壁部１５の外面側の部位には、蓋部材４の外周壁部４６を収容可能とする段差状の部位（凹部）が設けられることとする。また、長辺側側壁部１５の横幅方向全体（長辺側土台部１３の延在方向全体）にわたり、長辺側側壁部１５（長辺側土台部１３）の上部の外面側に蓋部材４の外周壁部４６を収容するための凹部が設けられる構成においては、当該凹部が部分的に設けられるような構成に比べ、長辺側側壁部１５（長辺側土台部１３）の上部の強度低下がより一層懸念される。この点、上記実施形態のように、側壁側係止部６１（土台側係止部７１）に対し補強構造を設けることによって、長辺側側壁部１５（長辺側土台部１３）の上部の強度を高めるといった作用効果がより顕著に奏される。 (B) In the above embodiment, the side wall side locking portion 61 is continuously provided over the entire width direction of the long side side wall portion 15, but the side wall side locking portion 61 is continuously provided over the entire width direction of the long side side wall portion 15. The unit 61 may be provided intermittently. However, in order to prevent the outer peripheral wall portion 46 of the lid member 4 covering the container body 3 from protruding outward from the outer surface of the long side side wall portion 15 of the container body 3, the upper side portion of the long side side wall portion 15 A stepped portion (recess) capable of accommodating the outer peripheral wall portion 46 of the lid member 4 is provided on the outer surface side portion of the long side side wall portion 15. Further, the lid member 4 is on the outer surface side of the upper portion of the long side side wall portion 15 (long side base portion 13) over the entire width direction of the long side side wall portion 15 (the entire extension direction of the long side base portion 13). In the configuration in which the recess for accommodating the outer peripheral wall portion 46 of the above is provided, the strength of the upper portion of the long side side wall portion 15 (long side base portion 13) is stronger than that in the configuration in which the recess is partially provided. There is even more concern about the decline. In this regard, as in the above embodiment, by providing a reinforcing structure to the side wall side locking portion 61 (base side locking portion 71), the upper portion of the long side side wall portion 15 (long side side base portion 13) is provided. The action effect such as increasing the strength is more remarkable.

尚、蓋付き容器２の短辺部側に関しても、短辺側側壁部１６の横幅方向全体にわたり側壁側係止部を設け、容器本体３に被せた蓋部材４が短辺側側壁部１６の外面よりも外方に突出しないように（例えば、面一となるように）構成してもよい。 Regarding the short side of the container 2 with a lid, a side wall locking portion is provided over the entire width direction of the short side side wall portion 16, and the lid member 4 covering the container body 3 is the short side side wall portion 16. It may be configured so as not to protrude outward from the outer surface (for example, to be flush with each other).

（ｃ）また、上記実施形態では、側壁側係止部６１の全体が補強リブ構造として構成されているが、蓋付き容器２をパレット５に載置した状態において、少なくとも側柱部５１、及び、中央柱部５２の上方に位置する部位が補強リブ構造とされていればよい。 (C) Further, in the above embodiment, the entire side wall side locking portion 61 is configured as a reinforcing rib structure, but in a state where the container 2 with a lid is placed on the pallet 5, at least the side pillar portion 51 and the side pillar portion 51 and , The portion located above the central pillar portion 52 may have a reinforcing rib structure.

さらに、上記実施形態では、土台側係止部７１には、補強リブ構造部７２と、２重壁構造部７３とが存在するように構成されているが、どちらか一方の補強構造に統一することとしてもよい。さらに、土台側係止部７１の補強構造は、蓋付き容器２をパレット５に載置した状態において、少なくとも側柱部５１、及び、中央柱部５２の上方に位置する部位に設けられていればよい。また、上記実施形態では、長辺側土台部１３のうち長辺側軸受部１７の挿入部３１に対応する部位においては土台側係止部７１が省略されているが、例えば、長辺側軸受部１７（挿入部３１及び軸支部３２）を、長辺側土台部１３の厚み方向における幅を狭くして底壁部１２の内周側に寄せて形成し、長辺側軸受部１７の上方の開口部に沿って、土台側係止部７１を延在させるように構成してもよい。但し、その場合、長辺側ヒンジ部２５の厚みを薄くしたりする必要が生じることから、上記実施形態のように、挿入部３１に対応する部位は、土台側係止部７１を省略することが望ましい。さらに、土台側係止部７１のうち、長辺側軸受部１７の軸支部３２に対応する部位においても、補強構造を具備するように構成してもよい。但し、その場合には、長辺側ヒンジ部２５の軸部２７を小さくする等の必要が生じることから、上記実施形態のように、軸支部３２に対応する部位は、補強構造を省略することが望ましい。 Further, in the above embodiment, the base side locking portion 71 is configured to have the reinforcing rib structure portion 72 and the double wall structure portion 73, but the reinforcing structure is unified to either one. It may be that. Further, the reinforcing structure of the base side locking portion 71 is provided at least in a portion located above the side pillar portion 51 and the central pillar portion 52 in a state where the container 2 with a lid is placed on the pallet 5. Just do it. Further, in the above embodiment, the base side locking portion 71 is omitted in the portion of the long side base portion 13 corresponding to the insertion portion 31 of the long side bearing portion 17, but for example, the long side bearing The portion 17 (insertion portion 31 and shaft support portion 32) is formed by narrowing the width of the long side base portion 13 in the thickness direction toward the inner peripheral side of the bottom wall portion 12 and above the long side bearing portion 17. The base side locking portion 71 may be extended along the opening of the base. However, in that case, since it is necessary to reduce the thickness of the long side hinge portion 25, the base side locking portion 71 is omitted from the portion corresponding to the insertion portion 31 as in the above embodiment. Is desirable. Further, the portion of the base side locking portion 71 corresponding to the shaft support portion 32 of the long side bearing portion 17 may also be configured to have a reinforcing structure. However, in that case, since it is necessary to make the shaft portion 27 of the long side hinge portion 25 smaller, the reinforcing structure is omitted from the portion corresponding to the shaft support portion 32 as in the above embodiment. Is desirable.

（ｄ）上記実施形態において、蓋部材４の形状については特に限定されるものではなく、組立状態にある容器本体３の上方の開口部を閉塞可能な天壁部４５と、蓋部材４を組立状態にある容器本体３に被せた状態において容器本体３の外周面と対向して略係止状態とされる外周壁部４６とを備え、蓋部材４が容器本体３の長辺側側壁部１５の外面よりも外方に突出しないように構成されていればよい。例えば、外周壁部４６において、下辺部の高さが異なる段差部が設けられていてもよい。また、蓋部材４を型成型により形成することとしてもよい。 (D) In the above embodiment, the shape of the lid member 4 is not particularly limited, and the top wall portion 45 capable of closing the upper opening of the container body 3 in the assembled state and the lid member 4 are assembled. The outer peripheral wall portion 46 is provided so as to face the outer peripheral surface of the container main body 3 and is substantially locked when the container main body 3 is covered with the lid member 4, and the lid member 4 is the long side side wall portion 15 of the container main body 3. It suffices if it is configured so as not to protrude outward from the outer surface of the. For example, the outer peripheral wall portion 46 may be provided with stepped portions having different heights of the lower side portions. Further, the lid member 4 may be formed by molding.

さらに、例えば、蓋部材４を組立状態の容器本体３に被せた場合に、蓋部材４の外周壁部４６が長辺側側壁部１５の上辺部に当接して支持され、天壁部４５が側壁側係止部６１から若干離間するように構成することも可能である。また、例えば、蓋部材４を折畳み状態の容器本体３に被せた場合に、蓋部材４の外周壁部４６が長辺側土台部１３の上辺部に当接して支持され、天壁部４５が土台側係止部７１から若干離間するように構成することも可能である。但し、上記実施形態のように、側壁側係止部６１や土台側係止部７１が蓋部材４の天壁部４５の下面と当接して支持可能な構成とすることで、蓋部材４の外周壁部４６の強度をそれ程高めなくても、運搬ユニット１の段積み状態において、外周壁部４６の変形等を防止することができる。 Further, for example, when the lid member 4 is put on the container body 3 in the assembled state, the outer peripheral wall portion 46 of the lid member 4 abuts and is supported by the upper side portion of the long side side wall portion 15, and the top wall portion 45 is supported. It is also possible to configure it so as to be slightly separated from the side wall side locking portion 61. Further, for example, when the lid member 4 is put on the container body 3 in the folded state, the outer peripheral wall portion 46 of the lid member 4 abuts and is supported by the upper side portion of the long side base portion 13, and the top wall portion 45 is supported. It is also possible to configure it so as to be slightly separated from the base side locking portion 71. However, as in the above embodiment, the side wall side locking portion 61 and the base side locking portion 71 can be supported by being in contact with the lower surface of the top wall portion 45 of the lid member 4. Even if the strength of the outer peripheral wall portion 46 is not increased so much, it is possible to prevent the outer peripheral wall portion 46 from being deformed or the like in the stacked state of the transport unit 1.
