In addition, the knob | pick part 62 inserted by the 1st attachment hole 72 is comprised so that it may not protrude outside the side part of the 1st side wall part 12a.
また、図１３、図１６等に示すように、蓋部材３には、閉状態にある場合に下方を向く下面側において、各連結部材５のフック部５２に対してそれぞれスライド可能に係止される一対のスライドレール８１が設けられている。図１３、図１４等に示すように、各スライドレール８１は、蓋部材３の下面から突出する突出部８２と、突出部８２の先端縁から蓋部材３の側辺部側に向けて直交する方向に突出し、連結部材５のフック部５２に対してスライド可能に係止される係止部８３とを備えている。さらに、スライドレール８１は、蓋部材３の回転軸の遠心方向に沿って、蓋部材３の開放側端縁３ａから軸側端縁３ｂにかけて延びている。
Further, as shown in FIGS. 13 and 16, the lid member 3 is slidably engaged with the hook portions 52 of the connecting members 5 on the lower surface side facing downward when in the closed state. A pair of slide rails 81 are provided. As shown in FIG. 13, FIG. 14, etc., each slide rail 81 is orthogonal to the protruding portion 82 protruding from the lower surface of the lid member 3 and the side edge of the lid member 3 from the tip edge of the protruding portion 82. A locking portion 83 that protrudes in the direction and is slidably locked with respect to the hook portion 52 of the connecting member 5 is provided. Further, the slide rail 81 extends from the open side edge 3 a to the shaft side edge 3 b of the lid member 3 along the centrifugal direction of the rotation shaft of the lid member 3.
そして、一対のスライドレール８１の係止部８３に対してそれぞれ連結部材５のフック部５２を引っ掛けた状態で、連結部材５を軸受部２９に挿入し、ピン部材６で連結部材５を第１側壁部１２ａに取付けることで、蓋部材３が連結部材５を介して第１側壁部１２ａに取付けられている（図１４、図１７（ｂ）等参照）。また、第１側壁部１２ａに対して回動可能な連結部材５に対して蓋部材３がスライド可能に取付けられることで、図１〜図４、図１７に示すように、蓋部材３は、連結部材５とともに第１側壁部１２ａに対して相対的に回動変位し、容器本体２の開口部を開閉可能に構成されるとともに、容器本体２の開口部に対してほぼ垂直になるまで開放された状態から、第１側壁部１２ａの外面に沿って連結部材５及び第１側壁部１２ａに対して相対的に下方へスライド変位し、第１側壁部１２ａの外面側に並設可能に構成されている。尚、軸受部２９の挿入凹部７１は、連結部材５のフック部５２に係止されたスライドレール８１の挿入をも許容するように形成されている。
The connecting member 5 is inserted into the bearing portion 29 in a state where the hook portions 52 of the connecting member 5 are hooked on the engaging portions 83 of the pair of slide rails 81, and the connecting member 5 is first connected by the pin member 6. By attaching to the side wall portion 12a, the lid member 3 is attached to the first side wall portion 12a via the connecting member 5 (see FIGS. 14, 17B, etc.). In addition, as shown in FIGS. 1 to 4 and 17, the lid member 3 is slidably attached to the connecting member 5 that is rotatable with respect to the first side wall portion 12 a. It is rotationally displaced relative to the first side wall portion 12a together with the connecting member 5, and is configured to be able to open and close the opening of the container body 2, and is opened until it is substantially perpendicular to the opening of the container body 2. From the applied state, it is configured to be slidable downward relative to the connecting member 5 and the first side wall part 12a along the outer surface of the first side wall part 12a, and arranged side by side on the outer surface side of the first side wall part 12a. Has been. The insertion recess 71 of the bearing portion 29 is formed to allow the insertion of the slide rail 81 locked to the hook portion 52 of the connecting member 5.
また、図１２等に示すように、蓋部材３が容器本体２の開口部を閉鎖した閉状態にある場合、連結部材５が第１姿勢とされるとともに、当該連結部材５の上端部が第１側壁部１２ａの上辺部と略面一となる（又は上辺部よりも下方に位置する）ようになっている。特に、本実施形態では、連結部材５が第１姿勢にある場合には、連結部材５が第１側壁部１２ａの外面から突出しないように構成されている。このように、蓋部材３が閉状態にある場合には、連結部材５が第１姿勢となって第１側壁部１２ａの外面から突出しなくなるため、蓋部材３が閉状態にある場合においても第１側壁部１２ａから突出しているような場合の各種不具合（設置スペースを余分に取ってしまったり、連結部材５が損傷し易くなってしまったりする等）を回避することができる。
Further, as shown in FIG. 12 and the like, when the lid member 3 is in a closed state in which the opening of the container body 2 is closed, the connecting member 5 is in the first posture, and the upper end portion of the connecting member 5 is in the first position. It is designed to be substantially flush with the upper side portion of one side wall portion 12a (or positioned below the upper side portion). In particular, in the present embodiment, when the connecting member 5 is in the first posture, the connecting member 5 is configured not to protrude from the outer surface of the first side wall portion 12a. Thus, when the lid member 3 is in the closed state, the connecting member 5 is in the first posture and does not protrude from the outer surface of the first side wall portion 12a. It is possible to avoid various problems (such as extra installation space or the connection member 5 being easily damaged) when protruding from the side wall portion 12a.
さらに、図８等に示すように、本実施形態のスライドレール８１は、蓋部材３の閉状態において、隣接側壁部としての第２側壁部１２ｂ及び第３側壁部１２ｃよりも容器本体２の内側に配置されるように構成されている。加えて、蓋部材３の閉状態においては、蓋部材３の下面のうちスライドレール８１よりも蓋部材３の側辺部側の部位等が、側壁部１２（第１側壁部１２ａ、第２側壁部１２ｂ、及び第３側壁部１２ｃ）の上辺部に載置されるようになっている。これにより、一対の蓋部材３を閉状態とすることで、容器本体２の開口部を完全に閉塞可能となっている。
Further, as shown in FIG. 8 and the like, the slide rail 81 according to the present embodiment is more inside the container body 2 than the second side wall portion 12b and the third side wall portion 12c as adjacent side wall portions when the lid member 3 is closed. It is comprised so that it may be arrange | positioned. In addition, when the lid member 3 is in the closed state, a portion of the lower surface of the lid member 3 that is closer to the side portion of the lid member 3 than the slide rail 81 is the side wall portion 12 (first side wall portion 12a, second side wall portion). Part 12b and the third side wall part 12c). Thereby, the opening part of the container main body 2 can be completely obstruct | occluded by making a pair of cover member 3 into a closed state.
一方、蓋部材３が第１側壁部１２ａの外面に沿って（上下に）延在した状態にある場合、連結部材５が第２姿勢とされるとともに、当該連結部材５のフック部５２は第１側壁部１２ａの外面よりも外方に突出位置するようになっている。これにより、蓋部材３全体を第１側壁部１２ａよりも外側に位置させ、蓋部材３を第１側壁部１２ａの外面側に並設させることが可能となっている。
On the other hand, when the lid member 3 is in a state extending (up and down) along the outer surface of the first side wall portion 12a, the connecting member 5 is in the second posture, and the hook portion 52 of the connecting member 5 is It protrudes outward from the outer surface of the one side wall portion 12a. As a result, the entire lid member 3 can be positioned outside the first side wall portion 12a, and the lid member 3 can be juxtaposed on the outer surface side of the first side wall portion 12a.
加えて、図１３等に示すように、スライドレール８１は、係止部８３の長手方向両端部と、蓋部材３の下面との間を連結するストッパー部８４を備えている。これにより、蓋部材３のスライド量を制限することができ、蓋部材３の脱落等を防止することができる。ちなみに、蓋部材３の閉状態や、容器本体２の開口部を開閉するべく蓋部材３を回動変位させている状態においては、蓋部材３の軸側端縁３ｂ側のストッパー部８４と、連結部材５のフック部５２とが略当接状態とされる。一方、蓋部材３の第１側壁部１２ａの外面側への並設状態においては、蓋部材３の開放側端縁３ａ側のストッパー部８４と、連結部材５のフック部５２とが略当接状態とされる。
In addition, as shown in FIG. 13 and the like, the slide rail 81 includes a stopper portion 84 that connects between both ends in the longitudinal direction of the locking portion 83 and the lower surface of the lid member 3. Thereby, the sliding amount of the lid member 3 can be limited, and the falling off of the lid member 3 can be prevented. Incidentally, in the closed state of the lid member 3 and the state in which the lid member 3 is rotationally displaced to open and close the opening of the container body 2, the stopper portion 84 on the side of the shaft side edge 3b of the lid member 3, The hook portion 52 of the connecting member 5 is brought into a substantially contact state. On the other hand, in the state where the first side wall portion 12a of the lid member 3 is juxtaposed to the outer surface side, the stopper portion 84 on the open side edge 3a side of the lid member 3 and the hook portion 52 of the connecting member 5 are substantially in contact with each other. State.
また、図１０、図１１、図１４等に示すように、連結部材５のフック部５２のうちスライドレール８１の突出部８２と対向する側端面５２ａは、蓋部材３（連結部材５）の回転軸線方向に対して直交する平坦面となっている上、蓋部材３のスライド方向において長い長方形状をなしている。特に、本実施形態では、蓋部材３のスライド方向において、フック部５２の側端面５２ａの幅は、ボス５５の外径よりも広く構成されている。さらに、本実施形態では、フック部５２の本体部５１からの突出長が、係止部８３の突出部８２からの突出長と同じか若干長く構成されており、フック部５２の側端面５２ａと、突出部８２とが当接可能に構成されている。例えば、蓋部材３が第１側壁部１２ａの外面側に並設した状態において正面視で時計回り方向に傾いた場合には、右側の連結部材５のフック部５２の側端面５２ａ上縁部と、右側のスライドレール８１の突出部８２とが当接するとともに、左側の連結部材５のフック部５２の側端面５２ａ下縁部と、左側のスライドレール８１の突出部８２とが当接し、それ以上の傾動変位が規制されることとなる。
As shown in FIGS. 10, 11, 14, etc., the side end surface 52 a of the hook portion 52 of the connecting member 5 that faces the protruding portion 82 of the slide rail 81 is rotated by the lid member 3 (connecting member 5). In addition to being a flat surface orthogonal to the axial direction, the cover member 3 has a long rectangular shape in the sliding direction. In particular, in the present embodiment, the width of the side end surface 52 a of the hook portion 52 is configured to be wider than the outer diameter of the boss 55 in the sliding direction of the lid member 3. Furthermore, in this embodiment, the protruding length of the hook portion 52 from the main body portion 51 is configured to be the same as or slightly longer than the protruding length of the locking portion 83 from the protruding portion 82, and the side end surface 52 a of the hook portion 52 is The projecting portion 82 is configured to be able to abut. For example, when the lid member 3 is arranged in parallel on the outer surface side of the first side wall portion 12a and tilts clockwise in front view, the upper edge portion of the side end surface 52a of the hook portion 52 of the right connecting member 5 The protrusion 82 of the right slide rail 81 comes into contact with the lower edge of the side end surface 52a of the hook 52 of the left connecting member 5, and the protrusion 82 of the left slide rail 81 comes into contact. The tilt displacement of is controlled.
尚、本実施形態では、蓋部材３が第１側壁部１２ａの外面側に並設した状態において、蓋部材３を第１側壁部１２ａのどちらかの側辺部側に水平にスライドさせて寄せることで、一対の連結部材５のうち一方の連結部材５のフック部５２の側端面５２ａと、対応するスライドレール８１の突出部８２とを面で当接させることができるとともに、この状態において、他方の連結部材５のフック部５２の側端面５２ａと、対応するスライドレール８１の突出部８２との間の距離（隙間）が１ｍｍ以上、５ｍｍ以下（例えば、約１ｍｍ）となっている。
In the present embodiment, the lid member 3 is horizontally slid toward one of the side portions of the first side wall portion 12a in a state where the lid member 3 is arranged side by side on the outer surface side of the first side wall portion 12a. Thus, the side end surface 52a of the hook portion 52 of one of the pair of connecting members 5 and the corresponding protruding portion 82 of the slide rail 81 can be brought into contact with each other in this state. The distance (gap) between the side end surface 52a of the hook portion 52 of the other connecting member 5 and the protruding portion 82 of the corresponding slide rail 81 is 1 mm or more and 5 mm or less (for example, about 1 mm).
加えて、フック部５２（側端面５２ａ）の蓋部材３のスライド方向における長さは、スライドレール８１の係止部８３と蓋部材３の下面との間の距離よりも大きくなっている。このため、フック部５２が、スライドレール８１の係止部８３と蓋部材３の下面との間の空間で回転することはなく、ひいては、連結部材５に対して蓋部材３が相対的に回動変位するようなこともない。
In addition, the length of the hook portion 52 (side end surface 52a) in the sliding direction of the lid member 3 is larger than the distance between the locking portion 83 of the slide rail 81 and the lower surface of the lid member 3. For this reason, the hook portion 52 does not rotate in the space between the locking portion 83 of the slide rail 81 and the lower surface of the lid member 3. As a result, the lid member 3 rotates relative to the connecting member 5. There is no dynamic displacement.
但し、フック部５２と、スライドレール８１の係止部８３、及び、蓋部材３の下面との間に全く隙間がないわけではなく、蓋部材３が完全に閉状態とされる際に蓋部材３の下面が側壁部１２の上辺部に対して広い範囲で当接するまで下降することを許容するのに十分な隙間が形成されている。このため、蓋部材３の回動動作をスムースに行うことができる、蓋部材３で容器本体２の開口部をぴったりと閉塞することができる、閉状態にある蓋部材３に対して下向きの力が付加されたとしても連結部材５に対してその力が作用することを回避し、連結部材５の損傷を防止することができる等の作用効果が奏される。
However, there is no gap between the hook portion 52, the locking portion 83 of the slide rail 81, and the lower surface of the lid member 3, and the lid member 3 is completely closed when the lid member 3 is completely closed. A sufficient gap is formed to allow the lower surface of 3 to descend until it contacts the upper side of the side wall portion 12 in a wide range. Therefore, the lid member 3 can be smoothly rotated, and the lid member 3 can close the opening of the container body 2 exactly. The downward force is applied to the lid member 3 in the closed state. Even if is added, it is possible to prevent the force from acting on the connecting member 5 and prevent the connecting member 5 from being damaged.
尚、上記隙間によって、蓋部材３が第１側壁部１２ａの外面側に並設した状態においても、蓋部材３の下面（この状態では第１側壁部１２ａの外面と対向している）が第１側壁部１２ａの外面に対して上下方向において広い範囲で当接するまでの蓋部材３の水平方向における変位が許容されるようになっていることとしてもよい。この場合、並設状態にある蓋部材３に対して第１側壁部１２ａに近接する側に力が付加されたとしても連結部材５に対してその力が作用することを回避することができるため、連結部材５の損傷を防止することができる。
Note that the lower surface of the lid member 3 (in this state, faces the outer surface of the first side wall portion 12a) even when the lid member 3 is arranged side by side on the outer surface side of the first side wall portion 12a due to the gap. The displacement of the lid member 3 in the horizontal direction until it comes into contact with the outer surface of the one side wall portion 12a in a wide range in the vertical direction may be allowed. In this case, even if a force is applied to the side close to the first side wall portion 12a with respect to the lid member 3 in the juxtaposed state, it can be avoided that the force acts on the connecting member 5. The damage of the connecting member 5 can be prevented.
また、図２、図１５等に示すように、蓋部材３には、蓋部材３の開放側端縁３ａから蓋部材３のうち容器本体２の開口部を閉鎖した閉状態で上方を向く上面を延長させるようにして突出形成された平面視略台形状の張出し部８５が設けられている。張出し部８５は、蓋部材３の開放側端縁３ａのうち、蓋部材３の回転軸線方向における中央部から、蓋部材３の一方の側辺部までの範囲において形成されている。さらに、蓋部材３の上面側には、一対の蓋部材３をともに閉状態とする際に、他方の蓋部材３の張出し部８５を収容可能な収容凹部８６が形成されている。そして、開状態にある一対の蓋部材３を同時に閉方向に変位させることで、張出し部８５の干渉を回避しつつ、一対の蓋部材３を閉状態とすることができ、一対の蓋部材３が閉状態とされると、各蓋部材３の張出し部８５が相手側の蓋部材３の収容凹部８６に収容されることとなる。これによって、張出し部８５を蓋部材３の上面から上方に突出しないように収納することができるとともに、蓋部材３同士が噛み合って、両者間の位置ずれや浮き上がりを防止することができる。
Moreover, as shown in FIG. 2, FIG. 15, etc., the cover member 3 has an upper surface facing upward from the open side edge 3a of the cover member 3 in the closed state in which the opening of the container body 2 is closed. A protruding portion 85 having a substantially trapezoidal shape in plan view is provided so as to protrude. The overhanging portion 85 is formed in a range from the central portion in the rotation axis direction of the lid member 3 to one side portion of the lid member 3 in the open side edge 3 a of the lid member 3. Furthermore, an accommodation recess 86 is formed on the upper surface side of the lid member 3 that can accommodate the overhanging portion 85 of the other lid member 3 when both the pair of lid members 3 are closed. And a pair of lid member 3 can be made into a closed state, avoiding interference of the overhang | projection part 85 by displacing a pair of lid member 3 in an open state simultaneously in a closing direction, and a pair of lid member 3 When is closed, the overhanging portion 85 of each lid member 3 is accommodated in the accommodation recess 86 of the counterpart lid member 3. As a result, the overhanging portion 85 can be accommodated so as not to protrude upward from the upper surface of the lid member 3, and the lid members 3 can be engaged with each other to prevent positional deviation or lifting between the two.
加えて、図２、図１６等に示すように、張出し部８５の下面側には、端縁等に沿って下方に突出する張出し側補強リブ８７が設けられる。また、図２、図１５等に示すように、収容凹部８６の上面側には、蓋部材３の開放側端縁３ａよりも内側に変位した位置において凹部側補強リブ８８が設けられている。さらに、張出し側補強リブ８７には、蓋部材３を閉状態とした場合に凹部側補強リブ８８と合致する位置において嵌合凹部８６が形成されている。これにより、一対の蓋部材３を閉状態とすることで、嵌合凹部８６が凹部側補強リブ８８に嵌合することとなり、閉状態とされた一対の蓋部材３が互いに離間するような相対変位を防止することができる。
In addition, as shown in FIGS. 2, 16, etc., overhanging side reinforcing ribs 87 are provided on the lower surface side of the overhanging portion 85 so as to protrude downward along the edge or the like. As shown in FIGS. 2, 15, and the like, a recess-side reinforcing rib 88 is provided on the upper surface side of the housing recess 86 at a position displaced inward from the open side edge 3 a of the lid member 3. Furthermore, a fitting recess 86 is formed in the overhanging side reinforcing rib 87 at a position that matches the recess side reinforcing rib 88 when the lid member 3 is closed. Thus, by closing the pair of lid members 3, the fitting recess 86 is fitted into the recess-side reinforcing rib 88, so that the pair of lid members 3 in the closed state are separated from each other. Displacement can be prevented.
尚、図４に示すように、蓋部材３を第１側壁部１２ａの外面側に並設させた状態では、蓋部材３の開放側端縁３ａは第１側壁部１２ａの上辺部と面一となっているが、張出し部８５は第１側壁部１２ａの上辺部よりも上方に突出している。さらに、かかる蓋部材３の並設状態では、蓋部材３の軸側端縁３ｂが第１側壁部１２ａの下辺部よりも下方に突出位置している。
As shown in FIG. 4, in the state where the lid member 3 is arranged side by side on the outer surface side of the first side wall portion 12a, the open side edge 3a of the lid member 3 is flush with the upper side portion of the first side wall portion 12a. However, the overhanging portion 85 protrudes upward from the upper side portion of the first side wall portion 12a. Furthermore, in the juxtaposed state of the lid member 3, the axial side edge 3 b of the lid member 3 protrudes below the lower side portion of the first side wall portion 12 a.
また、本実施形態では、このように蓋部材３を第１側壁部１２ａの外面側に並設させた状態としてから、一対の第１側壁部１２ａを同時に内側へ傾倒させていくことで、上記のように、容器本体２を折り畳むことができるようになる（図６参照）。さらに、図６、図９に示すように、蓋付き容器１を折り畳んだ状態では、第１土台部１４の上面全体が蓋部材３で覆われるとともに、蓋部材３の下面が第１土台部１４の上面に当接する（支持される）ように構成されている。尚、上記のように、寝かせ位置とされた第１側壁部１２ａの上方において一対の第１土台部１４間の空間が確保されるため、蓋部材３のスライドレール８１等をかかる空間に収容するとともに、蓋部材３の下面を第１土台部１４の上面に支持させることができる。
Further, in the present embodiment, after the lid member 3 is arranged in parallel on the outer surface side of the first side wall portion 12a in this way, the pair of first side wall portions 12a are tilted inward at the same time, thereby Thus, the container body 2 can be folded (see FIG. 6). Furthermore, as shown in FIGS. 6 and 9, in a state where the lidded container 1 is folded, the entire upper surface of the first base portion 14 is covered with the lid member 3, and the lower surface of the lid member 3 is covered with the first base portion 14. It is comprised so that it may contact | abut (support) on the upper surface. As described above, since the space between the pair of first base portions 14 is secured above the first side wall portion 12a in the laying position, the slide rails 81 and the like of the lid member 3 are accommodated in the space. At the same time, the lower surface of the lid member 3 can be supported on the upper surface of the first base portion 14.
加えて、図２、図４等に示すように、第２側壁部１２ｂ及び第３側壁部１２ｃの上辺部（上面）には、上方に突出する位置決め突部３５が設けられている。これに対応して、各蓋部材３には、閉状態とすることで、位置決め突部３５が挿通される位置決め開口部９１が形成されている。当該構成により、閉状態にある蓋部材３の水平方向における位置ずれが防止されることとなる。すなわち、蓋部材３が連結部材５に対してスライド可能に構成されていても、蓋部材３の閉状態においては、位置決め開口部９１に位置決め突部３５が挿通されること、及び、一方の蓋部材３の張出し部８５の張出し側補強リブ８７に形成された嵌合凹部８６が、他方の蓋部材の収容凹部８６に形成された凹部側補強リブ８８に嵌合すること等によって、蓋部材３の水平方向へのスライド変位が規制されるようになっている。
In addition, as shown in FIGS. 2, 4 and the like, a positioning protrusion 35 protruding upward is provided on the upper side (upper surface) of the second side wall 12b and the third side wall 12c. Correspondingly, a positioning opening 91 through which the positioning protrusion 35 is inserted is formed in each lid member 3 by being in a closed state. With this configuration, the horizontal displacement of the lid member 3 in the closed state is prevented. That is, even if the lid member 3 is configured to be slidable with respect to the connecting member 5, when the lid member 3 is closed, the positioning projection 35 is inserted into the positioning opening 91, and one lid is The fitting member 86 formed on the overhanging-side reinforcing rib 87 of the overhanging portion 85 of the member 3 is fitted into the depression-side reinforcing rib 88 formed in the housing recessed portion 86 of the other lid member. The slide displacement in the horizontal direction is regulated.
また、図１等に示すように、蓋部材３の上面には、蓋部材３の軸側端縁３ｂに沿って上方に突出するずれ止め凸部９２が設けられている。尚、ずれ止め凸部９２は、軸側端縁３ｂの長手方向両端部近傍には形成されていない。
Further, as shown in FIG. 1 and the like, the upper surface of the lid member 3 is provided with a shift protrusion 92 that projects upward along the axial end edge 3b of the lid member 3. In addition, the slip prevention convex part 92 is not formed in the longitudinal direction both ends part of the axial side edge 3b.
これに対し、底壁部１１の下面側には、組立状態にある容器本体２の開口部を蓋部材３で閉塞した状態、又は、蓋付き容器１を折り畳んだ状態において、蓋付き容器１同士を上下に積み重ねる（段積みする）場合に、下側の蓋付き容器１のずれ止め凸部９２を嵌入可能なずれ止め凹部１９が形成されている。ずれ止め凹部１９は、略正方形板状をなす底壁部１１の４つの側辺部にそれぞれ対応して形成されている。そして、蓋付き容器１同士を段積みした場合に、下側の蓋付き容器１のずれ止め凸部９２が、上側の蓋付き容器１のずれ止め凹部１９に嵌入することで、上下に段積みされた蓋付き容器１同士の水平方向における位置ずれが防止されるようになっている。
On the other hand, in the state where the opening of the container body 2 in the assembled state is closed by the lid member 3 or the container 1 with the lid is folded, In the case of stacking up and down (stacking), a stopper recess 19 is formed into which the stopper protrusion 92 of the lower lid-equipped container 1 can be inserted. The shift recess 19 is formed corresponding to each of the four side portions of the bottom wall portion 11 having a substantially square plate shape. When the containers with lids 1 are stacked, the protrusions 92 of the lower lid 1 are fitted into the recesses 19 of the upper lid 1, thereby stacking up and down. The positional deviation in the horizontal direction of the containers 1 with lids thus made is prevented.
尚、閉状態にある蓋部材３の位置決め開口部９１に挿通された位置決め突部３５は、図１等に示すように、蓋部材３の上面よりも上方にまで突出している。さらに、蓋部材３が閉状態にある蓋付き容器１の上に別の蓋付き容器１を段積みした場合には、下側の蓋付き容器１の位置決め突部３５についても上側の蓋付き容器１のずれ止め凹部１９に嵌入されるようになっている。これにより、位置決め効果がより一層奏されることとなる。
In addition, the positioning protrusion 35 inserted through the positioning opening 91 of the lid member 3 in the closed state protrudes above the upper surface of the lid member 3 as shown in FIG. Further, when another lidded container 1 is stacked on the lidded container 1 in which the lid member 3 is in the closed state, the upper lidded container is also used for the positioning projection 35 of the lower lidded container 1. 1 is inserted into the one recess stopper 19. Thereby, the positioning effect is further exhibited.
また、図１、図７、図１５等に示すように、本実施形態では、各蓋部材３の上面側には、それぞれ一対の凹部９４が形成されることによって、当該一対の凹部９４間に作業者が把持可能な把持部９５が設けられている。これにより、作業者は、把持部９５を持って（握って）蓋部材３を開閉動作させることができるようになっている。さらに、把持部９５（一対の凹部９４）は、蓋部材３の回転軸線に沿って延びている。特に、本実施形態では、蓋部材３の回転軸線方向が蓋部材３の長手方向となっているため、把持部９５は、蓋部材３の長手方向に沿って延在していることとなる。尚、本実施形態の凹部９４の深さ、すなわち、把持部９５の凹部９４底面からの突出長は約１０ｍｍとなっている。
In addition, as shown in FIGS. 1, 7, 15, and the like, in the present embodiment, a pair of recesses 94 are formed on the upper surface side of each lid member 3. A grip portion 95 that can be gripped by an operator is provided. As a result, the operator can open and close the lid member 3 while holding (holding) the grip portion 95. Further, the grip portion 95 (the pair of recesses 94) extends along the rotation axis of the lid member 3. In particular, in the present embodiment, since the rotation axis direction of the lid member 3 is the longitudinal direction of the lid member 3, the grip portion 95 extends along the longitudinal direction of the lid member 3. In addition, the depth of the recessed part 94 of this embodiment, ie, the protrusion length from the recessed part 94 bottom face of the holding part 95 is about 10 mm.
さらに、一対の凹部９４間の距離、すなわち、把持部９５の厚みは、１０ｍｍ〜７０ｍｍ程度（例えば、約２０ｍｍ）であって、図７に示すように、一対の凹部９４の内側空間は、把持部９５を構成する一対の隔壁部９６によって隔てられている。このため、例えば、一対の凹部９４が１枚の隔壁部のみで隔てられる、すなわち、把持部９５が１枚の隔壁部で構成されるような場合に比べて、把持部９５の剛性を高めることができる。さらに、一対の凹部９４間の距離が離れすぎず、かつ、近すぎないことで、作業者が一対の凹部９４のうち一方の凹部９４に親指を挿入し、他方の凹部９４に親指以外の複数の指を挿入して、把持部９５を比較的容易に把持できるようになっている。また、把持部９５（一対の凹部９４）は、蓋部材３の回転軸線方向における中央位置、かつ、蓋部材３の回転軸の遠心方向における中央位置を含む範囲に設けられている。
Further, the distance between the pair of recesses 94, that is, the thickness of the grip portion 95 is about 10 mm to 70 mm (for example, about 20 mm), and as shown in FIG. It is separated by a pair of partition walls 96 constituting the part 95. For this reason, for example, the rigidity of the grip portion 95 is increased as compared with the case where the pair of recesses 94 are separated by only one partition wall portion, that is, the grip portion 95 is configured by one partition wall portion. Can do. Further, since the distance between the pair of recesses 94 is not too far and not too close, the operator inserts a thumb into one recess 94 of the pair of recesses 94, and a plurality of other than the thumb is inserted into the other recess 94. Thus, the gripper 95 can be gripped relatively easily. Further, the grip portion 95 (the pair of recesses 94) is provided in a range including a central position in the rotation axis direction of the lid member 3 and a central position in the centrifugal direction of the rotation axis of the lid member 3.
また、図７等に示すように、蓋部材３の回転軸の遠心方向において並ぶ一対の凹部９４のうち、蓋部材３の開放側端縁３ａ側の凹部９４に対応して、把持部９５（隔壁部９６）の上縁部からかかる凹部９４の内周側（蓋部材３の開放側端縁３ａ側）に突出する庇部９７が設けられている。庇部９７の突出長は、庇部９７の厚みよりも若干長い程度となっている。尚、他方の凹部９４には庇部９７は設けられていない。また、庇部９７が設けられた凹部９４については、型成形時の型抜き性を考慮して、庇部９７が延出する隔壁部９６に対向する壁部が傾斜している。
Further, as shown in FIG. 7 and the like, of the pair of recesses 94 arranged in the centrifugal direction of the rotation axis of the lid member 3, the gripping portion 95 (corresponding to the recess 94 on the open side edge 3 a side of the lid member 3. A flange 97 protruding from the upper edge of the partition wall 96) to the inner peripheral side of the recess 94 (on the open side edge 3a side of the lid member 3) is provided. The protruding length of the flange portion 97 is slightly longer than the thickness of the flange portion 97. Note that the flange portion 97 is not provided in the other concave portion 94. Moreover, about the recessed part 94 provided with the collar part 97, the wall part facing the partition part 96 from which the collar part 97 extends inclines in consideration of the die-cutting property at the time of mold forming.
以上のように、各蓋部材３に対してそれぞれ把持部９５が設けられることによって、作業者は、蓋部材３が閉状態にある蓋付き容器１に対して一対の蓋部材３の突き合わせの位置が体の正面に来るようにして相対位置し、各蓋部材３の一対の凹部９４のうち開放側端縁３ａ側の凹部９４に親指を挿入して該親指を庇部９７に引っ掛けるとともに、親指以外の複数本の指を他方の凹部９４（蓋部材３の回転軸側の凹部９４）に挿入して把持部９５を握り、蓋部材３を持ち上げるようにして蓋部材３を開方向へ変位させることができる。
As described above, the grip portion 95 is provided for each lid member 3, so that the operator can butt the pair of lid members 3 against the lidded container 1 in which the lid member 3 is in the closed state. Is positioned relative to the front of the body, and a thumb is inserted into the recess 94 on the open end edge 3a side of the pair of recesses 94 of each lid member 3, and the thumb is hooked on the buttocks 97. A plurality of other fingers are inserted into the other concave portion 94 (the concave portion 94 on the rotating shaft side of the lid member 3), the grip portion 95 is gripped, and the lid member 3 is displaced in the opening direction so as to lift the lid member 3. be able to.
また、折り畳み状態にある蓋付き容器１の容器本体２を箱型に組み立てる場合には、上記のように、先ず一対の第１側壁部１２ａを起立位置へと変位させる。本実施形態では、第１側壁部１２ａ自体には持ち手が形成されていないが、第１側壁部１２ａの外面側に並設状態となっている蓋部材３の把持部９５を持って寝かせ位置にある第１側壁部１２ａを起立位置へと変位させることができる。尚、第１側壁部１２ａを起立位置とする際には、第１側壁部１２ａに対して蓋部材３が第１側壁部１２ａの上方に抜け出してしまわないように、蓋部材３に対して極力第１側壁部１２ａの回転軸側に力を掛けつつ外側に引っ張ることとなる。さらに、第１側壁部１２ａが起立位置とされると、第１側壁部１２ａの下縁部よりも下方にまで延びる蓋部材３が第１土台部１４の外面（外壁部４３）に係止されるため、第１側壁部１２ａの内側への傾倒変位が抑制される。
Moreover, when assembling the container main body 2 of the container 1 with the lid | cover in a folded state in a box shape, a pair of 1st side wall part 12a is first displaced to an upright position as mentioned above. In this embodiment, a handle is not formed on the first side wall portion 12a itself, but the sleeping position is held by holding the grip portion 95 of the lid member 3 arranged in parallel on the outer surface side of the first side wall portion 12a. 1st side wall part 12a in can be displaced to a standing position. When the first side wall portion 12a is set to the upright position, the lid member 3 is as far as possible from the first side wall portion 12a so that the lid member 3 does not slip out of the first side wall portion 12a. The first side wall portion 12a is pulled outward while applying a force to the rotating shaft side. Further, when the first side wall portion 12a is in the standing position, the lid member 3 extending downward from the lower edge portion of the first side wall portion 12a is locked to the outer surface (outer wall portion 43) of the first base portion 14. Therefore, the tilt displacement to the inside of the first side wall portion 12a is suppressed.
以上詳述したように、本実施形態によれば、各蓋部材３に把持部９５が設けられているため、蓋部材３の上面側から把持部９５を持って蓋部材３を開閉動作させることができる。従って、蓋部材３の開閉作業性を向上させることができるとともに、蓋部材３と側壁部１２（第１側壁部１２ａ）との間に手を挟む等の事態を回避することができる。また、把持部９５は、蓋部材３の上面側において一対の凹部９４を設けることによって形成されているため、把持部９５の配置を比較的自由に設定することができる。特に、本実施形態では、把持部９５が蓋部材３の回転軸線方向における中央部付近に設けられている。このため、蓋部材３を（片手でも）バランスよく持つことができ、蓋部材３を開閉させる際に蓋部材３が変形してしまうといった事態を抑制しつつ、蓋部材３の開閉作業性をより向上させることができる。
As described above in detail, according to the present embodiment, since each lid member 3 is provided with the grip portion 95, the lid member 3 is opened and closed by holding the grip portion 95 from the upper surface side of the lid member 3. Can do. Therefore, the opening / closing workability of the lid member 3 can be improved, and a situation such as a hand being caught between the lid member 3 and the side wall portion 12 (first side wall portion 12a) can be avoided. Further, since the grip portion 95 is formed by providing a pair of concave portions 94 on the upper surface side of the lid member 3, the arrangement of the grip portion 95 can be set relatively freely. In particular, in the present embodiment, the grip portion 95 is provided near the center portion of the lid member 3 in the rotation axis direction. Therefore, the lid member 3 can be held in a well-balanced manner (even with one hand), and the lid member 3 can be opened / closed more efficiently while suppressing the situation where the lid member 3 is deformed when the lid member 3 is opened / closed. Can be improved.
さらに、把持部９５は、一対の凹部９４を設けることによって形成されているため、把持部９５が蓋部材３の上面よりも上方に突出するといった事態を回避することができる。従って、例えば、蓋付き容器１同士を段積みするような場合の利便性、安定性の向上等を図ることができる。また、蓋部材３に一対の凹部９４、ひいては、把持部９５が形成されることによって、蓋部材３の強度向上を図ることができ、蓋部材３の変形等を抑制することができる。
Furthermore, since the grip portion 95 is formed by providing a pair of recesses 94, it is possible to avoid a situation in which the grip portion 95 protrudes above the upper surface of the lid member 3. Therefore, for example, it is possible to improve convenience and stability when stacking the containers 1 with lids. Further, by forming the pair of recesses 94 and thus the grip portion 95 in the lid member 3, the strength of the lid member 3 can be improved, and deformation of the lid member 3 can be suppressed.
また、把持部９５は、蓋部材３の長手方向に沿って延在している。このため、把持部９５を形成することで蓋部材３の撓み変形を抑制するといった効果がより一層奏されることとなる。従って、蓋部材３の開閉に際しての蓋部材３の変形等をより確実に抑制することができ、開閉作業性の向上、シール性の向上、第１側壁部１２ａの外面側への並設時や折り畳み時の収納性の向上等を図ることができる。
In addition, the grip portion 95 extends along the longitudinal direction of the lid member 3. For this reason, the effect that the bending deformation of the lid member 3 is suppressed by forming the grip portion 95 is further exhibited. Therefore, the deformation of the lid member 3 at the time of opening and closing the lid member 3 can be more reliably suppressed, improving the opening and closing workability, improving the sealing performance, and arranging the first side wall portion 12a on the outer surface side. It is possible to improve the storage property when folded.
さらに、各蓋部材３に形成された一対の凹部９４のうち蓋部材３の開放側端縁３ａ側の凹部９４に対応して、把持部９５の上辺部からかかる凹部９４の内周側に突出する庇部９７が設けられている。このため、把持部９５を持つ際に庇部９７に指を引っ掛けることができ、蓋部材３の持ち易さを向上させることができる。従って、蓋部材３の開閉作業性の向上をより一層図ることができる。
Further, of the pair of concave portions 94 formed in each lid member 3, the inner side of the concave portion 94 protrudes from the upper side portion of the grip portion 95 corresponding to the concave portion 94 on the open side edge 3 a side of the lid member 3. A flange 97 is provided. For this reason, when holding the holding part 95, a finger | toe can be hooked on the collar part 97 and the easiness of holding the cover member 3 can be improved. Accordingly, it is possible to further improve the opening / closing workability of the lid member 3.
特に、一対の凹部９４のうち庇部９７が設けられた側の凹部９４は、作業者が把持部９５を持つ際に、作業者の親指が挿入される側の凹部９４である。このため、把持部９５を持つ際の親指の引っ掛かりが良くなり、蓋部材３の持ち易さをより確実に向上させることができる。尚、親指と、親指以外の指とで把持部９５を挟んで蓋部材３を持った状態において、親指だけで把持部９５の側面（隔壁部９６）を圧接支持するのに比べ、親指以外の複数の指で把持部９５の側面（隔壁部９６）を圧接支持する方が容易であり、滑り難い。このため、一対の凹部９４のうち親指が挿入される側に庇部９７を設けることで、蓋部材３の持ち易さを向上させるといった作用効果がより確実に奏されることとなる。
In particular, the concave portion 94 on the side where the collar portion 97 is provided in the pair of concave portions 94 is the concave portion 94 on the side where the operator's thumb is inserted when the operator holds the grip portion 95. For this reason, the catch of the thumb when holding the grip portion 95 is improved, and the ease of holding the lid member 3 can be improved more reliably. It should be noted that in a state in which the lid member 3 is held with the grip portion 95 sandwiched between the thumb and a finger other than the thumb, the side surface (partition wall portion 96) of the grip portion 95 is pressed against and supported by the thumb alone. It is easier to press and support the side surface (partition wall portion 96) of the grip portion 95 with a plurality of fingers, and it is difficult to slip. For this reason, by providing the collar portion 97 on the side where the thumb is inserted in the pair of concave portions 94, the effect of improving the ease of holding the lid member 3 is more reliably achieved.
また、蓋部材３を第１側壁部１２ａの外面側に並設させた状態において、容器本体２を折り畳み可能となっている本実施形態においては、第１側壁部１２ａを起立位置と寝かせ位置とに変位させる際にも、蓋部材３の把持部９５を持って、蓋部材３及び第１側壁部１２ａともども傾動動作させることとなる。このとき、本実施形態のように、一対の凹部９４のうち蓋部材３の開放側端縁３ａ側の凹部９４に庇部９７が設けられることによって、親指を庇部９７に引っ掛けて、蓋部材３が第１側壁部１２ａの上辺部よりも上方に抜け出さないように下側に押さえつつ、蓋部材３及び第１側壁部１２ａを傾動させることができる。これに対し、例えば、蓋部材３の開放側端縁３ａ側の凹部９４に庇部９７がなく、蓋部材３の軸側端縁３ｂ側の凹部９４に庇部が設けられるような場合には、蓋部材３が抜け出さないように押さえておくことが比較的困難となる上、親指以外の指が庇部に引っ掛かって蓋部材３が持ち上がり易くなってしまうことが懸念される。従って、特に本実施形態のように容器本体２が折り畳み可能な蓋付き容器１の場合には、庇部９７を蓋部材３の開放側端縁３ａ側の凹部９４に対応して設けることが望ましい。
Further, in the present embodiment in which the container body 2 can be folded in a state where the lid member 3 is arranged side by side on the outer surface side of the first side wall portion 12a, the first side wall portion 12a is set to the standing position and the laying position. Also when displacing, the holding member 95 of the lid member 3 is held and the lid member 3 and the first side wall portion 12a are both tilted. At this time, as in the present embodiment, the lid portion 97 is provided in the concave portion 94 on the open side edge 3a side of the lid member 3 of the pair of concave portions 94, so that the thumb is hooked on the collar portion 97, and the lid member The lid member 3 and the first side wall part 12a can be tilted while pressing down 3 so that 3 does not escape upward from the upper side part of the first side wall part 12a. On the other hand, for example, in the case where the recess 94 on the open side edge 3a side of the lid member 3 does not have the flange 97 and the flange 94 is provided on the recess 94 on the axis side edge 3b side of the lid member 3. In addition, it is relatively difficult to hold the lid member 3 so that it does not come out, and there is a concern that the finger other than the thumb may be caught by the buttocks and the lid member 3 will be easily lifted. Therefore, particularly in the case of the container 1 with a lid in which the container body 2 can be folded as in the present embodiment, it is desirable to provide the flange 97 corresponding to the recess 94 on the open side edge 3a side of the lid member 3. .
また、連結部材５は、第１側壁部１２ａの上辺部に形成された挿入凹部７１に挿入されるようにして軸受部２９に軸支されるようになっている。このため、蓋部材３の回転軸線方向において連結部材５が軸受部２９によって保護されることとなる。従って、連結部材５に対してその他の部材等が衝突し、連結部材５が損傷等してしまうといった事態を防止することができる。さらには、連結部材５をその両側方において支持可能であるため、連結部材５及び蓋部材３をより安定して支持可能であるとともに、連結部材５の両側方が軸受部２９の内側面で挟まれることによって、蓋部材３の回転軸線方向における連結部材５の変形を防止することができる。
Further, the connecting member 5 is pivotally supported by the bearing portion 29 so as to be inserted into the insertion recess 71 formed in the upper side portion of the first side wall portion 12a. For this reason, the connecting member 5 is protected by the bearing portion 29 in the rotation axis direction of the lid member 3. Therefore, it is possible to prevent a situation in which other members collide with the connecting member 5 and the connecting member 5 is damaged. Furthermore, since the connecting member 5 can be supported on both sides thereof, the connecting member 5 and the lid member 3 can be supported more stably, and both sides of the connecting member 5 are sandwiched between the inner surfaces of the bearing portion 29. As a result, the deformation of the connecting member 5 in the direction of the rotation axis of the lid member 3 can be prevented.
さらに、蓋部材３の閉状態においてスライドレール８１が第２側壁部１２ｂと第３側壁部１２ｃとの間に位置するとともに、蓋部材３が第２側壁部１２ｂ及び第３側壁部１２ｃの上辺部に支持されるように構成されている。このため、蓋部材３の閉状態においてスライドレール８１が露出しなくなり、スライドレール８１の保護を図ることができる。従って、スライドレール８１に対してその他の部材等が衝突し、スライドレール８１が損傷等してしまうといった事態を防止することができる。さらには、スライドレール８１に埃等の異物が堆積してしまうことを抑制することができ、蓋部材３のスムースなスライド動作を比較的容易に維持することができる。
Further, in the closed state of the lid member 3, the slide rail 81 is positioned between the second side wall portion 12b and the third side wall portion 12c, and the lid member 3 is located on the upper side portion of the second side wall portion 12b and the third side wall portion 12c. It is comprised so that it may be supported by. For this reason, the slide rail 81 is not exposed when the lid member 3 is closed, and the slide rail 81 can be protected. Therefore, it is possible to prevent a situation in which other members collide with the slide rail 81 and the slide rail 81 is damaged. Furthermore, it is possible to prevent foreign matter such as dust from accumulating on the slide rail 81, and the smooth sliding operation of the lid member 3 can be maintained relatively easily.
また、蓋部材３の閉状態において、連結部材５が第１側壁部１２ａの上辺部よりも上方に突出せず、かつ、スライドレール８１が第２側壁部１２ｂ及び第３側壁部１２ｃに干渉することもない。このため、第２側壁部１２ｂ及び第３側壁部１２ｃの上辺部と、蓋部材３の下面とを当接させることができ、容器本体２に対して蓋部材３が浮いてしまう（比較的大きな隙間ができてしまう）といった事態を回避することができる。従って、容器本体２の開口部を蓋部材３で好適に閉鎖することができる。さらには、蓋部材３の閉状態において、蓋部材３を連結部材５やスライドレール８１で支持しなくても済む。従って、連結部材５やスライドレール８１の損傷等を防止することができる。特に、蓋付き容器１同士の段積み等が可能で、蓋部材３に対して比較的大きな負荷がかかり得る構成においては、かかる作用効果が一層顕著なものとなる。
Further, in the closed state of the lid member 3, the connecting member 5 does not protrude above the upper side of the first side wall portion 12a, and the slide rail 81 interferes with the second side wall portion 12b and the third side wall portion 12c. There is nothing. For this reason, the upper side part of the 2nd side wall part 12b and the 3rd side wall part 12c, and the lower surface of the cover member 3 can be contact | abutted, and the cover member 3 will float with respect to the container main body 2 (relatively big). It is possible to avoid such a situation that a gap is formed. Therefore, the opening of the container body 2 can be suitably closed with the lid member 3. Furthermore, the lid member 3 need not be supported by the connecting member 5 or the slide rail 81 in the closed state of the lid member 3. Therefore, damage to the connecting member 5 and the slide rail 81 can be prevented. In particular, in a configuration in which the containers with lids 1 can be stacked and the like, and a relatively large load can be applied to the lid member 3, such operational effects become even more remarkable.
さらに、連結部材５のフック部５２のうち、スライドレール８１の突出部８２と当接可能な側端面５２ａは、蓋部材３（連結部材５）の回転軸線方向に対して直交する平坦面となっている上、蓋部材３のスライド方向において、フック部５２の側端面５２ａの幅が、ボス５５の外径よりも広く構成されている。このように側端面５２ａの幅をある程度確保することで、フック部５２と突出部８２との間に蓋部材３のスライドをスムースに行わせるための隙間を確保したとしても、蓋部材３を第１側壁部１２ａの外面に沿ってスライドさせる際に、蓋部材３が左右に（正面視で時計回りや反時計回り方向に）若干量傾いただけで、一対の連結部材５のフック部５２の側端面５２ａと、一対のスライドレール８１の突出部８２とが当接し、それ以上の傾倒変位が規制されるように構成することができる。従って、フック部５２の側端面５２ａと突出部８２との間に全く隙間がなかったり、或いは、蓋部材３をスライドさせる際に蓋部材３が左右に大きく傾倒してしまってつっかえたりすることを回避することができ、蓋部材３をスライドさせる際の作業性の向上等を図ることができる。加えて、並設状態にある蓋部材３が左右に傾いて第１側壁部１２ａの側辺部よりも側方に突出してしまうといった事態を回避することができ、蓋部材３の損傷防止等を図ることができる。
Further, in the hook portion 52 of the connecting member 5, the side end surface 52 a that can come into contact with the protruding portion 82 of the slide rail 81 is a flat surface orthogonal to the rotational axis direction of the lid member 3 (connecting member 5). In addition, the width of the side end surface 52 a of the hook portion 52 is configured to be wider than the outer diameter of the boss 55 in the sliding direction of the lid member 3. As described above, by securing the width of the side end surface 52a to some extent, even if a gap for smoothly sliding the lid member 3 between the hook portion 52 and the projecting portion 82 is secured, the lid member 3 can be When sliding along the outer surface of the one side wall portion 12a, the lid member 3 is slightly tilted left and right (clockwise or counterclockwise in front view), so that the hook portion 52 side of the pair of connecting members 5 The end surface 52a and the protrusion part 82 of a pair of slide rail 81 contact | abut, and it can comprise so that inclination displacement beyond it may be controlled. Therefore, there is no gap between the side end surface 52a of the hook portion 52 and the protruding portion 82, or when the lid member 3 is slid, the lid member 3 is largely tilted to the left and right and is replaced. This can be avoided, and the workability when the lid member 3 is slid can be improved. In addition, it is possible to avoid a situation in which the lid member 3 in the juxtaposed state tilts to the left and right and protrudes to the side rather than the side portion of the first side wall portion 12a, thereby preventing damage to the lid member 3 and the like. Can be planned.

(B) In the above embodiment, the connecting member 5 is attached to the first side wall portion 12a by the pin member 6. However, the connecting member 5 itself is integrally provided with a shaft pin and is directly attached to the first side wall portion 12a. You may comprise so that rotation is possible. In addition, when employ | adopting the said structure, it is desirable that the removal direction from the 1st side wall part 12a of the connection member 5 and the direction where the connection member 5 is pulled when opening and closing the cover member 3 differ as much as possible. That is, the connecting member 5 is configured to be detachable in the rotational axis direction of the lid member 3 (connecting member 5), or the connecting member 5 is configured so that the removing direction is downward and the inner peripheral direction of the container body 2. It is good as well.
（ｃ）上記実施形態において、蓋部材３の下面側において、把持部９５を構成する一対の隔壁部９６間（一対の凹部９４間）を連結するリブを設けることとしてもよい。この場合、把持部９５、ひいては、蓋部材３の強度をより一層向上させることができる。尚、上記実施形態において、一対の凹部９４が一枚の隔壁部のみを挟んで隣接するように構成することも可能であるが、この場合、把持部９５の強度の低下を招くおそれがある上、持ち難くなるため、上記実施形態のように、把持部９５は相対する一対の隔壁部９６によって構成されることが望ましい。
(C) In the above embodiment, on the lower surface side of the lid member 3, ribs that connect between the pair of partition walls 96 (between the pair of recesses 94) constituting the grip portion 95 may be provided. In this case, it is possible to further improve the strength of the grip portion 95 and, consequently, the lid member 3. In the above-described embodiment, the pair of recesses 94 may be configured to be adjacent to each other with only one partition wall interposed therebetween. However, in this case, the strength of the grip portion 95 may be reduced. In order to make it difficult to hold, it is desirable that the grip portion 95 is constituted by a pair of opposing partition portions 96 as in the above embodiment.
（ｄ）上記実施形態では、把持部９５（一対の凹部９４）は、蓋部材３の長手方向でもある蓋部材３の回転軸線方向に沿って延びているが、その他の方向、例えば、図１８に示すように、蓋部材３の回転軸の遠心方向に沿って延びるように構成してもよい（但し、参考例）。また、把持部９５を蓋部材３の回転軸の遠心方向に延在させる場合には、一対の凹部９４の両方に対応して、把持部９５の上辺部から凹部９４の内周側に突出する庇部９７を設けることとする。すなわち、かかる構成においては、一対の凹部９４のどちらに対しても親指が挿入される可能性があるため、両方に庇部９７を設けておくことで、蓋部材３の開閉作業性の向上を確実に図ることができる。
(D) In the above embodiment, the grip portion 95 (the pair of recesses 94) extends along the rotational axis direction of the lid member 3 which is also the longitudinal direction of the lid member 3, but the other direction, for example, FIG. As shown in FIG. 6, the lid member 3 may be configured to extend along the centrifugal direction of the rotation shaft (however, a reference example) . Further, when the grip portion 95 extends in the centrifugal direction of the rotation shaft of the lid member 3, the grip portion 95 protrudes from the upper side portion of the grip portion 95 toward the inner peripheral side of the recess portion 94 corresponding to both of the pair of recess portions 94. A collar 97 is provided. That is, in such a configuration, there is a possibility that the thumb may be inserted into either of the pair of recesses 94, so that the opening / closing workability of the lid member 3 can be improved by providing the collar portion 97 on both. It can be done reliably.
また、各蓋部材３にそれぞれ形成される一対の凹部９４の形状や大きさは特に限定されるものではなく、把持部９５を構成する一対の凹部９４のうち、少なくとも一方（蓋部材３の開放側端縁３ａ側の凹部９４）は親指を挿入可能に構成され、他方は親指以外の指を複数本挿入可能に構成されていればよい。加えて、各蓋部材３には一対の凹部９４が設けられているが、少なくとも一対で設けられていれば把持部９５を構成することができ、例えば、所定の凹部９４の内側の空間を２つに区切るようにして壁部を形成することとしてもよい。
The shape and size of the pair of recesses 94 formed in each lid member 3 are not particularly limited, and at least one of the pair of recesses 94 constituting the grip portion 95 (opening of the lid member 3). The recess 94) on the side edge 3a side may be configured so that a thumb can be inserted, and the other may be configured so that a plurality of fingers other than the thumb can be inserted. In addition, each lid member 3 is provided with a pair of recesses 94. However, if at least a pair of recesses 94 are provided, the grip portion 95 can be configured. The wall portion may be formed so as to be divided into two.
尚、上記実施形態のように、一対の凹部９４のうち一方だけに対応して庇部９７を設ける構成とすることで、アンダーカット形状となる部位を減少させることができ、蓋部材３を成形する金型構造の簡略化等を図ることができる。
In addition, by setting it as the structure which provides the collar part 97 corresponding to only one among a pair of recessed parts 94 like the said embodiment, the site | part used as an undercut shape can be reduced and the cover member 3 is shape | molded. It is possible to simplify the mold structure to be performed.
（ｅ）上記実施形態では、連結部材５のフック部５２の側端面５２ａは、蓋部材３（連結部材５）の回転軸に対して直交する平坦面であり、かつ、蓋部材３のスライド方向に沿って長い長方形状をなしているが、当該側端面５２ａに対して碁盤目状に溝を形成したり、側端面５２ａの長手方向中間位置に切欠き部を形成したり、側端面５２ａを正面視略楕円形状や５角形以上の多角形状等にしたりしてもよい。
(E) In the above embodiment, the side end surface 52a of the hook portion 52 of the connecting member 5 is a flat surface orthogonal to the rotation axis of the lid member 3 (connecting member 5) and the sliding direction of the lid member 3 Is formed in a rectangular pattern along the side end face 52a, a notch is formed in the middle position in the longitudinal direction of the side end face 52a, or the side end face 52a is The shape may be a substantially elliptical shape in front view or a polygonal shape of pentagon or more.
さらに、上記実施形態では、フック部５２の本体部５１からの突出長が、係止部８３の突出部８２からの突出長と同じか若干長く構成されているが、スライドレール８１の係止部８３の突出長をフック部５２の突出長よりも長くして、係止部８３の側端面が、連結部材５の本体部５１のうちフック部５２とボス５５との間の部位に当接可能に構成することとしてもよい。この場合においても、蓋部材３のスライド方向において、本体部５１のうち係止部８３の側端面と当接可能な部位の幅をある程度確保することで、蓋部材３のスライドに際しての左右への傾きを極力抑制することができる。但し、連結部材５の本体部５１のうちフック部５２が設けられる端部の方が中間部位よりも幅を広げ易い上、フック部５２の幅を広げることでスライドレール８１の係止状態の安定化やフック部５２の強化等も同時に図られるため、上記実施形態のように、フック部５２の側端面５２ａを突出部８２に当接可能に構成することが望ましい。
Furthermore, in the above-described embodiment, the protruding length of the hook portion 52 from the main body 51 is the same as or slightly longer than the protruding length of the locking portion 83 from the protruding portion 82. The protruding length of 83 is longer than the protruding length of the hook portion 52, and the side end surface of the locking portion 83 can abut on the portion of the main body portion 51 of the connecting member 5 between the hook portion 52 and the boss 55. It is good also as comprising. Also in this case, in the sliding direction of the lid member 3, by securing a certain width of the portion of the main body 51 that can contact the side end surface of the locking portion 83, the lid member 3 can be moved to the left and right when the lid member 3 is slid. Tilt can be suppressed as much as possible. However, in the main body 51 of the connecting member 5, the end where the hook 52 is provided is easier to expand than the intermediate portion, and the locking state of the slide rail 81 is stabilized by increasing the width of the hook 52. Since, for example, the reinforcement of the hook portion 52 is simultaneously achieved, it is desirable that the side end surface 52a of the hook portion 52 be configured to be able to contact the protruding portion 82 as in the above embodiment.
また、上記実施形態では、スライドレール８１の係止部８３は突出部８２から蓋部材３の側辺部側に突出しているが、蓋部材３の回転軸線方向における蓋部材３の中央部側に突出するように構成してもよい。この場合、さらに、蓋部材３の閉状態において、スライドレール８１（突出部８２）が第２側壁部１２ｂ及び第３側壁部１２ｃの内面に近接配置されることとしてもよい。この場合、蓋部材３と容器本体２との水平方向における位置ずれをスライドレール８１の側面（非使用面）によっても規制することができ、連結部材５の負担軽減を図ることができる。
In the above embodiment, the locking portion 83 of the slide rail 81 protrudes from the protruding portion 82 toward the side portion of the lid member 3, but on the central portion side of the lid member 3 in the rotation axis direction of the lid member 3. You may comprise so that it may protrude. In this case, the slide rail 81 (projecting portion 82) may be disposed close to the inner surfaces of the second side wall portion 12b and the third side wall portion 12c when the lid member 3 is closed. In this case, the horizontal displacement between the lid member 3 and the container body 2 can be restricted by the side surface (non-use surface) of the slide rail 81, and the burden on the connecting member 5 can be reduced.
加えて、上記実施形態では、底壁部１１が略正方形板状をなしているが、略長方形板状であってもよい。また、上記実施形態では、第２側壁部１２ｂ及び第３側壁部１２ｃを寝かせ位置とした場合に第２側壁部１２ｂ及び第３側壁部１２ｃの一部が上下に重なるように構成されているが、重なることなく水平方向に並んで収容されるように構成してもよい。
In addition, in the said embodiment, although the bottom wall part 11 has comprised the substantially square plate shape, a substantially rectangular plate shape may be sufficient. Moreover, in the said embodiment, when the 2nd side wall part 12b and the 3rd side wall part 12c are made into the sleeping position, it is comprised so that a part of 2nd side wall part 12b and the 3rd side wall part 12c may overlap up and down. , And may be configured to be accommodated side by side in the horizontal direction without overlapping.
（ｆ）上記実施形態では、蓋付き容器１はポリプロピレンにより構成されているが、ポリエチレン、ＰＥＴ、ポリアミド等その他の樹脂材料により構成されることとしてもよい。
