Further, in this state, the first engaging projecting piece 23 formed on the long side side wall 21L of the surrounding wall portion 21 engages with the first engaging recess 33 formed on the long side portion of the inner surface member 31 to surround the surrounding member 31. The second engaging projecting piece 24 formed on the short side side wall 21S of the wall portion 21 engages with the second engaging recess 34 formed on the short side portion of the inner surface member 31. As described above, in the lid 10, the claw portion 25B and the step 35D are locked, the first engaging protrusion 23 and the first engaging recess 33 are engaged, and the second engaging protrusion 24 and the second engagement are engaged. It is regulated that the inner surface member 31 falls off from the outer surface member 11 due to the engagement of the joint recess 34.

図７（Ａ）、図７（Ｂ）、図８（Ａ）及び図８（Ｂ）に示されるように、短辺側壁２１Ｓの主板１２からの突出量が内面部材３１の厚みと略同じになっていて、長辺側壁２１Ｌの主板１２からの突出量が短辺側壁２１Ｓの主板１２からの突出量よりも大きくなっているので、蓋体１０では、内面部材３１の外周面の全体が包囲壁部２１によって覆われる。そして、長辺側壁２１Ｌの飛出部２２が内面部材３１の下面よりも下方側に飛び出す。 As shown in FIGS. 7 (A), 7 (B), 8 (A), and 8 (B), the amount of protrusion of the short side wall surface 21S from the main plate 12 is substantially the same as the thickness of the inner surface member 31. Since the amount of protrusion of the long side side wall 21L from the main plate 12 is larger than the amount of protrusion of the short side side wall 21S from the main plate 12, the entire outer peripheral surface of the inner surface member 31 is surrounded by the lid body 10. It is covered by the wall portion 21. Then, the protruding portion 22 of the long side side wall 21L protrudes downward from the lower surface of the inner surface member 31.

図８（Ａ）に示されるように、外面部材１１の第２係合突片２４は、内面部材３１の第２係合凹部３４と係合した状態で、内面部材３１の下面と略面一に配置される。ここで、上述の如く、第２係合突片２４は、第１係合突片２３と係合突部２５の爪部２５Ｂの何れよりも主板１２から離れて下方に配置されている。したがって、第１係合突片２３は、第１係合凹部３３内で内面部材３１の下面に対して奥まって配置され（図８（Ｂ）参照）、係合突部２５は、係止孔３５内で内面部材３１の下面に対して奥まって配置される。 As shown in FIG. 8A, the second engaging projecting piece 24 of the outer surface member 11 is substantially flush with the lower surface of the inner surface member 31 in a state of being engaged with the second engaging recess 34 of the inner surface member 31.

Here, as described above, the second engaging projecting piece 24 is arranged below either the first engaging projecting piece 23 or the claw portion 25B of the engaging projecting portion 25, away from the main plate 12. Therefore, the first engaging protrusion 23 is arranged recessed with respect to the lower surface of the inner surface member 31 in the first engaging recess 33 (see FIG. 8B), and the engaging protrusion 25 is a locking hole. It is arranged recessed in 35 with respect to the lower surface of the inner surface member 31.

図２（Ａ）及び図２（Ｂ）に示されるように、蓋体１０が容器５０（詳細には、組立状態の容器５０）の開口部５０Ａに取り付けられると、包囲壁部２１が開口部５０Ａに嵌合され、外面部材３１のうち包囲壁部２１より外側の部分が容器５０の長辺容器側壁５２及び短辺容器側壁５３の上に載置される。そして、包囲壁部２１内に収容された内面部材３１が、容器５０内に露出し、容器底壁５１の容器内面部材５５に対向する。 As shown in FIGS. 2A and 2B, when the lid 10 is attached to the opening 50A of the container 50 (specifically, the assembled container 50), the surrounding wall 21 opens. It is fitted to 50A, and the portion of the outer surface member 31 outside the surrounding wall portion 21 is placed on the long side container side wall 52 and the short side container side wall 53 of the container 50. Then, the inner surface member 31 housed in the surrounding wall portion 21 is exposed in the container 50 and faces the container inner surface member 55 of the container bottom wall 51.

図９（Ａ）及び図９（Ｂ）に示されるように、蓋体１０は、折畳状態の容器５０の上にも載置可能に構成されている。蓋体１０が折畳状態の容器５０の上に載置されると、内面部材３１が長辺容器側壁５２の上に重ねられ、外面部材１１のうち包囲壁部２１より外側の部分が長辺土手部５１Ａの上に載置される。このとき、蓋体１０の包囲壁部２１及び内面部材３１が容器５０の長辺土手部５１Ａどうしの間に挟まれることで、蓋体１０が容器５０に対して容器５０の短辺方向に移動することが抑えられている。 As shown in FIGS. 9A and 9B, the lid 10 is configured to be able to be placed on the folded container 50 as well. When the lid 10 is placed on the folded container 50, the inner surface member 31 is superposed on the long side container side wall 52, and the portion of the outer surface member 11 outside the surrounding wall portion 21 is the long side. It is placed on the bank portion 51A. At this time, the surrounding wall portion 21 and the inner surface member 31 of the lid 10 are sandwiched between the long side bank portions 51A of the container 50, so that the lid 10 moves in the short side direction of the container 50 with respect to the container 50. It is suppressed to do.

図１０に示されるように、折畳状態の容器５０では、長辺土手部５１Ａと長辺容器側壁５２の間に受容凹部５７が形成されている。そして、蓋体１０の包囲壁部２１の飛出部２２は、受容凹部５７に受容される。なお、本実施形態では、長辺容器側壁５２のうち折畳状態で長辺土手部５１Ａに臨む部分の上面に陥没部５２Ａが形成されていて（図１１参照）、受容凹部５７に受容された飛出部２２の突部２２Ｔが長辺容器側壁５２と干渉することが抑えられている。 As shown in FIG. 10, in the folded container 50, a receiving recess 57 is formed between the long side bank portion 51A and the long side container side wall 52. Then, the protruding portion 22 of the surrounding wall portion 21 of the lid 10 is received by the receiving recess 57. In the present embodiment, the recessed portion 52A is formed on the upper surface of the portion of the long side container side wall 52 facing the long side bank portion 51A in the folded state (see FIG. 11), and is received by the receiving recess 57. It is suppressed that the protruding portion 22T of the protruding portion 22 interferes with the side wall 52 of the long side container.

折畳状態の容器５０に蓋体１０を載置する際には、まず、蓋体１０の長辺を容器５０の長辺土手部５１Ａと略平行に配置し、蓋体１０を傾けて包囲壁部２１の一方の長辺側壁２１Ｌを容器５０の一方の長辺容器側壁５２の上に置く。そして、蓋体１０を容器５０の上で滑らせて、一方の長辺側壁２１Ｌを一方の長辺土手部５１Ａに近づける。すると、一方の長辺側壁２１Ｌの飛出部２２が、容器５０において一方の長辺土手部５１と一方の長辺容器側壁５２の間に形成された受容凹部５７に受容される。次いで、蓋体１０を水平にして、他方の長辺側壁２１Ｌの飛出部２２を、容器５０において他方の長辺土手部５１と他方の長辺容器側壁５２の間に形成された受容凹部５７に受容させる。すると、蓋体１０の外面部材１１（詳細には、包囲壁部２１より外方側の部分）が一方と他方の長辺土手部５１の上に載置される。以上により、折畳状態の容器５０の上に蓋体１０が載置される。 When placing the lid 10 on the folded container 50, first, the long side of the lid 10 is arranged substantially parallel to the long side bank portion 51A of the container 50, and the lid 10 is tilted to surround the surrounding wall. One long side side wall 21L of the portion 21 is placed on one long side container side wall 52 of the container 50. Then, the lid 10 is slid on the container 50 to bring one long side side wall 21L closer to the other long side bank portion 51A. Then, the protruding portion 22 of one long side side wall 21L is received by the receiving recess 57 formed between the one long side bank portion 51 and the one long side container side wall 52 in the container 50. Next, with the lid 10 horizontal, the protruding portion 22 of the other long side side wall 21L is formed in the container 50 between the other long side bank portion 51 and the other long side container side wall 52. To accept. Then, the outer surface member 11 of the lid 10 (specifically, the portion on the outer side of the surrounding wall portion 21) is placed on one and the other long side bank portion 51. As described above, the lid 10 is placed on the folded container 50.

ここで、上述したように、包囲壁部２１の長辺側壁２１Ｌに形成された第１係合突片２３は、第１係合凹部３３内で内面部材３１の下面に対して奥まって配置されるので、蓋体１０を傾けて包囲壁部２１の長辺側壁２１Ｌを長辺容器側壁５２の上に置いたときに、第１係合突片２３が衝撃や負荷を受けることが抑制される。これにより、第１係合突片２３の破損が抑制される。 Here, as described above, the first engaging projection piece 23 formed on the long side side wall 21L of the surrounding wall portion 21 is arranged recessed in the first engaging recess 33 with respect to the lower surface of the inner surface member 31. Therefore, when the long side side wall 21L of the surrounding wall portion 21 is placed on the long side container side wall 52 by tilting the lid 10, the first engaging projecting piece 23 is suppressed from receiving an impact or a load. .. As a result, damage to the first engaging projectile 23 is suppressed.

本実施形態の蓋体１０及び蓋体付き容器７０によれば、以下の優れた効果を奏することができる。即ち、蓋体１０では、外面部材１１の下面に突設された包囲壁部２１が内面部材３１の外周面を取り囲むので、内面部材３１の外周面が容器５０の開口部５０Ａの内周面と擦れることが抑えられる。これにより、内面部材３１の破損が抑制される。 According to the lid 10 and the container with lid 70 of the present embodiment, the following excellent effects can be obtained. That is, in the lid 10, the surrounding wall portion 21 projecting from the lower surface of the outer surface member 11 surrounds the outer peripheral surface of the inner surface member 31, so that the outer peripheral surface of the inner surface member 31 is the inner peripheral surface of the opening 50A of the container 50. Rubbing is suppressed. As a result, damage to the inner surface member 31 is suppressed.

また、包囲壁部２１には、内面部材３１の下面よりも下方側に飛び出る飛出部２２が形成されているので、内面部材３１を下方に向けた状態で蓋体１０が地面や作業台の上に載置された場合であっても、内面部材３１が地面や作業台に接触することが抑えられる。これにより、内面部材３１の汚染が抑制される。特に、容器５０が食品用容器である場合には、蓋体１０が容器５０に取り付けられた状態で容器５０内に露出する内面部材３１の汚染を防ぐことは重要である。 Further, since the surrounding wall portion 21 is formed with a protruding portion 22 that protrudes downward from the lower surface of the inner surface member 31, the lid 10 is placed on the ground or a workbench with the inner surface member 31 facing downward. Even when it is placed on top, the inner surface member 31 is prevented from coming into contact with the ground or the workbench. As a result, contamination of the inner surface member 31 is suppressed. In particular, when the container 50 is a food container, it is important to prevent contamination of the inner surface member 31 exposed inside the container 50 with the lid 10 attached to the container 50.

また、本実施形態の蓋体付き容器７０では、長辺土手部５１Ａの上に蓋体１０の外面部材３１が載置されたときに、長辺土手部５１Ａと折り曲げ側壁５２との間に形成された受容凹部５７に蓋体１０の包囲壁部２１の飛出部２２が受容される。これにより、組立状態の容器５０だけでなく折畳状態の容器５０にも蓋体１０を被せることが可能となる。 Further, in the container 70 with a lid of the present embodiment, when the outer surface member 31 of the lid 10 is placed on the long side bank portion 51A, it is formed between the long side bank portion 51A and the bent side wall 52. The protruding portion 22 of the surrounding wall portion 21 of the lid 10 is received in the receiving recess 57. This makes it possible to cover not only the assembled container 50 but also the folded container 50 with the lid 10.

なお、本実施形態では、容器５０の容器底壁５１と長辺容器側壁５２と短辺容器側壁５３がそれぞれ、特許請求の範囲に記載した「底壁」と「第１側壁」と「第２側壁」に相当し、長辺土手部５１Ａが特許請求の範囲に記載した「土手部」に相当する。 In the present embodiment, the container bottom wall 51, the long side container side wall 52, and the short side container side wall 53 of the container 50 are the "bottom wall", the "first side wall", and the "second side wall" described in the claims, respectively.
