Description

本発明は、容器の蓋体の開閉及び係止に関する構造であって、特に携帯用小型箱体の蓋体に係るものに関する。 The present invention relates to a structure relating to opening / closing and locking of a lid of a container, particularly relating to a lid of a small portable box.

従来から、容器本体の側壁から突出した支持体にヒンジ軸を形成して、蓋から突出したフックをヒンジ軸に係合させるヒンジ構造を用いた先行技術は存在した。 Conventionally, there has been a prior art using a hinge structure in which a hinge shaft is formed on a support projecting from the side wall of the container body and a hook protruding from the lid is engaged with the hinge shaft.

特開２０００−８０８５２号公報Japanese Unexamined Patent Publication No. 2000-80852 特開２００３−２０８５２号公報Japanese Unexamined Patent Publication No. 2003-20852

特許文献にかかる先行技術は、いずれも容器と蓋体と、からなる箱体で、ヒンジ構造による開閉構造を有するものである。例えば、特許文献１の図２に示すように、バックルかぎ４を蓋２に取り付けられた丸棒のかぎ受け３に係合させて、蓋をロックするものである。 The prior art in the patent document is a box body composed of a container, a lid body, and an opening / closing structure having a hinge structure. For example, as shown in FIG. 2 of Patent Document 1, the buckle key 4 is engaged with the key receiver 3 of the round bar attached to the lid 2 to lock the lid.

ところが、このような蓋体の開閉及び係止構造では、スムーズな開閉が実現できず、特に携帯用小型箱体には適さないものであった。すなわち、特許文献にかかる先行技術の箱体を開閉するためには、まずバックルかぎ４の係合を解除し、そして、使用者がバックルかぎ４から蓋体２を持ち替えて、蓋体２を開けなければならず、２段階の操作が必要であった。このような開閉及び係止構造は、大型の箱体であれば必要であったが、特に携帯用小型箱体のように大型箱体よりも何度も開閉するものであれば、このような２段階の開閉操作ではなく、よりスムーズな開閉が求められていた。 However, such an opening / closing and locking structure of the lid cannot realize smooth opening / closing, and is not particularly suitable for a small portable box. That is, in order to open and close the box body of the prior art according to the patent document, the buckle key 4 is first disengaged, and then the user changes the lid body 2 from the buckle key 4 and opens the lid body 2. It had to be done and a two-step operation was required. Such an opening / closing and locking structure was necessary for a large box body, but such a structure for opening and closing a large box body more often than a large box body such as a portable small box body. There was a demand for smoother opening and closing instead of a two-step opening and closing operation.

そこで、本発明は、ヒンジ構造を有する箱体であって、使用者がワンタッチでスムーズに開閉を行い得る箱体の開閉及び係止構造を提供するものである。 Therefore, the present invention provides a box body having a hinge structure, which can be smoothly opened and closed by a user with one touch.

As shown in FIGS. 1 and 2, the box body 1 of the present invention includes a lid body 2, a main body 3, and grip opening / closing bodies 4 and 4. The main body 3 has a container-like shape (box shape) with an open upper part, and the opened portion is opened and closed by a lid body 2.

本説明において、図１の箱体１の一方の把持開閉体４がある手前側を前方とし、奥側の把持開閉体４を後方とし、本体３の長手方向を左右方向として説明する。また、箱体１の高さ方向を鉛直方向、垂直方向とし、この鉛直方向、垂直方向に直交する方向を水平方向として説明する。また、図１に示す本体３の上方を蓋体２により閉じた状態を閉蓋状態とし、把持開閉体４を回動してヒンジ軸１４ａ、１４ａとの係合を解除可能にした状態を開蓋状態とし、この開蓋状態から図２に示すように蓋体２を開ける動作を開蓋動作として説明する。 In this description, the front side where one grip opening / closing body 4 of the box body 1 of FIG. 1 is located is the front side, the gripping opening / closing body 4 on the back side is the rear side, and the longitudinal direction of the main body 3 is the left-right direction. Further, the height direction of the box body 1 will be described as a vertical direction and a vertical direction, and the direction orthogonal to the vertical direction and the vertical direction will be described as a horizontal direction. Further, the state in which the upper part of the main body 3 shown in FIG. 1 is closed by the lid body 2 is set to the closed state, and the state in which the gripping opening / closing body 4 is rotated to be disengaged from the hinge shafts 14a and 14a is opened. The operation of opening the lid body 2 from this opened state as shown in FIG. 2 will be described as a lid opening operation.

本実施形態における箱体１は、比較的小型のものであり、両側方の長手方向長さを２１３ｍｍ、前後方向長さを１０６ｍｍとし、本体３の高さを２８ｍｍとした容器である。主に工具におけるビス等の小型物や釣り用のハリス等を適宜開閉して取出しし易くしたものである。 The box body 1 in the present embodiment is a relatively small container, which has a length in the longitudinal direction of 213 mm on both sides, a length in the front-rear direction of 106 mm, and a height of the main body 3 of 28 mm. Mainly, small objects such as screws in tools and Harris for fishing are opened and closed as appropriate to make it easier to take out.

箱体１は、本体３の長手方向（左右方向）の両側において、前後端から延長してループ状に突出する保持部５、５を有している。この保持部５、５を有することにより、使用者はカラビナ等のフックを掛けて箱体１をズボンのベルト掛けに取り付けて携帯することができ、小型容器であることで携帯しながらワンタッチで開閉して内容物を取り出すことが可能になる。 The box body 1 has holding portions 5 and 5 extending from the front and rear ends and projecting in a loop shape on both sides of the main body 3 in the longitudinal direction (left-right direction). By having the holding portions 5 and 5, the user can hang a hook such as a carabiner and attach the box body 1 to the belt hook of the trousers to carry it, and since it is a small container, it can be opened and closed with one touch while carrying it. It becomes possible to take out the contents.

まず、本実施形態の本体３について説明する。本体３は、図２、４に示すように、四方に丸みを持たせた方形状の底面の端縁から立ち上がる壁面を有し、上方を開放した箱状の形態を有する。図５に示すように、前側の前側壁１１ａと、後側の後側壁１１ｂと、保持部５、５が配置された両側方の側方壁と、からなり、底面の四方の丸みに合わせて各壁面の接合部分（角部分）もアールを形成している。前側壁１１ａ、後側壁１１ｂ及び両側方の側方壁の上部付近から外方に突出する鍔部１２が各壁面の全周に亘り形成される（図４参照）。 First, the main body 3 of the present embodiment will be described. As shown in FIGS. 2 and 4, the main body 3 has a wall surface rising from the edge of a square bottom surface having rounded sides, and has a box-like shape with an open upper part. As shown in FIG. 5, it is composed of a front side wall 11a on the front side, a rear side wall 11b on the rear side, and side walls on both sides on which the holding portions 5 and 5 are arranged, and is aligned with the roundness on all four sides of the bottom surface. The joints (corners) of each wall surface also form a radius. The front side wall 11a, the rear side wall 11b, and the flange portion 12 projecting outward from the vicinity of the upper portion of the side walls on both sides are formed over the entire circumference of each wall surface (see FIG. 4).

図２、４に示すように、本体３の前側壁１１ａには、鍔部１２より更に外方に突出するように、一対の軸支持部１３ａ、１３ａが２ヶ所（後側も同じく２カ所）形成される。この一対の軸支持部１３ａ、１３ａ間に、比較的短く、本体３の長手方向と同じ方向を軸方向とするヒンジ軸１４ａ、１４ａが両端を支持されるように配置され、ヒンジ軸１４ａは太さを一定とした略丸棒形状としている。 As shown in FIGS. It is formed. Between the pair of shaft support portions 13a and 13a, hinge shafts 14a and 14a, which are relatively short and have the same direction as the longitudinal direction of the main body 3 as the axial direction, are arranged so as to support both ends, and the hinge shaft 14a is thick. It has a substantially round bar shape with a constant shape.

また、２つのヒンジ軸１４ａ、１４ａの間には、比較的長い支持軸１５ａが同じく軸支持部１３ａ、１３ａにより両端を支持するように配置されるが、中央に位置する軸支持部１３ａ、１３ａの間には、支持軸が配置されていない開放部１６を形成している。支持軸１５ａはヒンジ軸１４ａと長手方向長さが異なるが、その太さ及び形状を同じくしている。本体３の後側壁１１ｂにも、一対の軸支持部１３ｂ、１３ｂ、ヒンジ軸１４ｂ、支持軸１５ｂ、開放部１６を前側壁１１ａと前後対称にして同じように形成している。 Further, between the two hinge shafts 14a and 14a, a relatively long support shaft 15a is also arranged so as to support both ends by the shaft support portions 13a and 13a, but the shaft support portions 13a and 13a located at the center thereof. An open portion 16 in which a support shaft is not arranged is formed between the two. The support shaft 15a has a different length in the longitudinal direction from the hinge shaft 14a, but has the same thickness and shape. A pair of shaft support portions 13b, 13b, a hinge shaft 14b, a support shaft 15b, and an opening portion 16 are also formed on the rear side wall 11b of the main body 3 in the same manner in a front-rear symmetrical manner with the front side wall 11a.

ヒンジ軸１４ａ及び支持軸１５ａは、鍔部１２の外方側端縁よりも外方に位置し、ヒンジ軸１４ａ及び支持軸１５ａと本体３の鍔部１２との間に隙間を形成している。後述のとおり、この隙間に把持開閉体４、４のフック３２、３２が回動可能に挿入される。 The hinge shaft 14a and the support shaft 15a are located outside the outer edge of the flange portion 12, and form a gap between the hinge shaft 14a and the support shaft 15a and the flange portion 12 of the main body 3. .. As will be described later, the hooks 32, 32 of the gripping opening / closing bodies 4, 4 are rotatably inserted into this gap.

次に、蓋体２について説明する。蓋体２は、図１乃至３に示すように、本体３の上方の開放端を覆うように形成された形態であり、角を丸めた方形状のものである。蓋体２の外周端縁は、本体３の外周端縁よりも一回り広く、本体３から外方に突出した鍔部１２の外周端縁に沿うようにしている。蓋体２の外周付近は湾曲して、その端縁部分の厚み面２８が下方を向くように形成しており、この外周端縁の厚み面２８が鍔部１２に当接して蓋体２が本体３を閉じるようにしている。 Next, the lid 2 will be described. As shown in FIGS. 1 to 3, the lid 2 has a form formed so as to cover the upper open end of the main body 3, and has a square shape with rounded corners. The outer peripheral edge of the lid 2 is one size wider than the outer peripheral edge of the main body 3, and is aligned with the outer peripheral edge of the flange portion 12 protruding outward from the main body 3. The vicinity of the outer periphery of the lid 2 is curved so that the thick surface 28 of the edge portion thereof faces downward, and the thick surface 28 of the outer peripheral edge abuts on the collar portion 12 to form the lid 2. The main body 3 is closed.

なお、蓋体２の外周端縁の厚み面２８は、全周に亘り形成され上方に凹むパッキン溝と、この溝に嵌合したパッキンと、を有しており、容器内を密閉可能としている。パッキンは例えばゴムやシリコンからなるループ状のチューブとしている。 The thickness surface 28 of the outer peripheral edge of the lid 2 has a packing groove formed over the entire circumference and recessed upward, and a packing fitted in the groove, so that the inside of the container can be sealed. .. The packing is, for example, a loop-shaped tube made of rubber or silicon.

図６に示すように、蓋体２の表面の前側及び後側には、後述する把持開閉体４、４の係止状態の取り付け位置となる部分の周囲を略コの字状で囲むような***部２１、２１が形成されている。蓋体２の表面は、各々***部２１、２１により囲まれた前後方向外側の部分（把持開閉体４、４を配置する部分、***部２１、２１により囲まれる部分）をその他の部分よりも一段低くなる凹部２７、２７が形成される。この凹部２７、２７の両側方から一部突出した複数の凸部２５、２５を形成し、後述するように閉蓋状態で把持開閉体４、４と当接する。 As shown in FIG. 6, on the front side and the rear side of the surface of the lid body 2, the portions of the gripping opening / closing bodies 4 and 4 to be attached in the locked state, which will be described later, are surrounded by a substantially U-shape. The raised portions 21, 21 are formed. The surface of the lid 2 has an outer portion in the front-rear direction surrounded by the raised portions 21 and 21 (a portion on which the gripping opening / closing bodies 4 and 4 are arranged and a portion surrounded by the raised portions 21 and 21) more than the other portions. Recesses 27, 27 that are one step lower are formed. A plurality of convex portions 25, 25 that partially protrude from both sides of the concave portions 27, 27 are formed and come into contact with the gripping opening / closing bodies 4, 4 in a closed state as described later.

***部２１、２１の長手方向中央部分には、一部***しない非***部２６、２６がある。この非***部２６、２６が形成されることで、閉蓋状態で使用者が把持開閉体４、４の下方に指を挿入し易くしており、把持開閉体４、４を把持して開蓋状態にするように回動させることができる。 In the central portion of the raised portions 21 and 21 in the longitudinal direction, there are non-raised portions 26 and 26 that are not partially raised. By forming the non-raised portions 26, 26, it is easy for the user to insert a finger under the gripping opening / closing bodies 4, 4 in the closed state, and the gripping opening / closing bodies 4, 4 are gripped and opened. It can be rotated so as to be in a lid state.

図３に示すように、***部２１、２１の両側方端は、把持開閉体４、４を回動可能に支持するために、蓋体２から外側に突出し、下方に垂下した取付部２１ａ、２１ａが形成されている。この取付部２１ａ、２１ａにはヒンジ軸１４ａ、１４ａと同軸方向に並ぶ丸穴が形成される。 As shown in FIG. 3, both side ends of the raised portions 21, 21 project outward from the lid 2 and hang downward in order to rotatably support the gripping opening / closing bodies 4, 4. 21a is formed. Round holes aligned coaxially with the hinge shafts 14a and 14a are formed in the mounting portions 21a and 21a.

次に、把持開閉体４、４について説明する。本説明において、一方（前方）の把持開閉体４とヒンジ軸１４ａ、１４ａとの形状は、他方（後方）の把持開閉体４とヒンジ軸１４ｂ、１４ｂとの形状と同じであるため、他方の把持開閉体４の説明を省略する。本実施形態に係る把持開閉体４、４は、図１、２、７に示すように、主に、４つのヒンジ軸１４ａ、１４ａに係合するフック３２、３２と、このフック３２、３２の上端から連続して立ち上がる４つの立ち上がり部３３、３３と、この４つの立ち上がり部３３、３３の上端から連続して１つの把持部３４が形成される。 Next, the gripping opening / closing bodies 4 and 4 will be described. In the present description, the shape of one (front) gripping opening / closing body 4 and the hinge shafts 14a and 14a is the same as the shape of the other (rear) gripping opening / closing body 4 and the hinge shafts 14b and 14b. The description of the grip opening / closing body 4 will be omitted. As shown in FIGS. 1, 2 and 7, the gripping opening / closing bodies 4 and 4 according to the present embodiment mainly include hooks 32 and 32 that engage with the four hinge shafts 14a and 14a, and hooks 32 and 32. Four rising portions 33, 33 that continuously rise from the upper ends and one grip portion 34 that continuously rises from the upper ends of the four rising portions 33, 33 are formed.

図３に示すように、把持開閉体４、４は、把持部３４から長手方向両側（左右両側）から垂下した係合部３１、３１から、さらに左右方向に突出した突起軸３１ａ、３１ａが、蓋体２の取付部２１ａ、２１ａに形成された丸穴に回動自在に係合することで、回動自在に配置される。この係合部３１、３１に形成された突起軸３１ａは、ヒンジ軸１４ａ、１４ａと支持軸１５ａ、１５ａと同軸方向に並ぶように形成されることから、把持開閉体４、４を回動すると、フック３２、３２がヒンジ軸１４ａ、１４ａの周囲を回動するヒンジ構造とすることができる。 As shown in FIG. 3, the gripping opening / closing bodies 4 and 4 have protrusion shafts 31a and 31a protruding in the left-right direction from the engaging portions 31 and 31 hanging from both sides (left and right sides) in the longitudinal direction from the grip portion 34. It is rotatably arranged by rotatably engaging with the round holes formed in the mounting portions 21a and 21a of the lid body 2. Since the protrusion shafts 31a formed on the engaging portions 31 and 31 are formed so as to be aligned coaxially with the hinge shafts 14a and 14a and the support shafts 15a and 15a, when the grip opening / closing bodies 4 and 4 are rotated. , The hooks 32, 32 can have a hinge structure that rotates around the hinge shafts 14a, 14a.

また、把持開閉体４、４の左右方向の中央に、後述の被係止部２４の左右方向の端部に回動自在に係合する補助係合部３６が形成され、この補助係合部３６にも係合部３１の突起軸３１ａと同じく同軸方向に並ぶ同径の突起軸があり、被係止部２４の左右方向の端部に形成された丸穴に嵌まり込む。これにより、把持開閉体４の回動や蓋体２の分離を補助・補強している。 Further, an auxiliary engaging portion 36 that rotatably engages with the left-right end portion of the locked portion 24, which will be described later, is formed at the center of the gripping opening / closing bodies 4 and 4 in the left-right direction. The 36 also has a protruding shaft having the same diameter arranged in the same coaxial direction as the protruding shaft 31a of the engaging portion 31, and fits into a round hole formed at the left-right end of the locked portion 24. As a result, the rotation of the grip opening / closing body 4 and the separation of the lid body 2 are assisted / reinforced.

このように、把持開閉体４、４は突起軸３１ａ、３１ａとヒンジ軸１４ａ、１４ａとが同軸方向に形成されていることから、回動をスムースにできる。さらに、仮に突起軸３１ａ、３１ａがヒンジ軸１４ａ、１４ａの上方に形成された場合にはフック３２、３２がより本体３側に回動してしまうなど、コンパクトな構成とすることができない。 As described above, since the protrusion shafts 31a and 31a and the hinge shafts 14a and 14a are formed in the coaxial direction of the gripping opening / closing bodies 4 and 4, the rotation can be made smooth. Further, if the protrusion shafts 31a and 31a are formed above the hinge shafts 14a and 14a, the hooks 32 and 32 will rotate more toward the main body 3, and a compact configuration cannot be obtained.

また、把持開閉体４、４は前側と後側に２つ配置され、各々独立して開閉することができ、一方の把持開閉体４のフック３２、３２を解除すると、もう一方の把持開閉体４のフック３２、３２がヒンジ軸１４ａ、１４ａの周囲を回動するヒンジ構造として、蓋体２が開く開蓋状態となる。また、両方の把持開閉体４、４のフック３２、３２を解除すると、蓋体２を完全に外すことも可能になる。 In addition, two gripping opening / closing bodies 4 and 4 are arranged on the front side and the rear side, and each can be opened and closed independently. When the hooks 32 and 32 of one gripping opening / closing body 4 are released, the other gripping opening / closing body As a hinge structure in which the hooks 32, 32 of 4 rotate around the hinge shafts 14a, 14a, the lid body 2 is opened. Further, when the hooks 32 and 32 of both the gripping opening / closing bodies 4 and 4 are released, the lid body 2 can be completely removed.

次に、把持開閉体４、４と本体３のヒンジ軸１４ａ、１４ａとフック３２、３２との係合について説明する。図１に示すように、把持部３４は斜め上方に湾曲しながら後方（本体の中央方向）に延長した形状として、その左右方向寸法を前後方向寸法よりも長く形成される。図１、６に示すように、把持部３４は、上述のとおり、閉蓋状態で凸部２５、２５に当接して、***部２１に囲まれた蓋体２の凹部２７、２７を覆うように配置される。図７（ａ）に示すように、閉蓋状態では、把持部３４は、その上面が***部２１の上面から緩やかに湾曲するような形状となる。 Next, the engagement between the grip opening / closing bodies 4 and 4 and the hinge shafts 14a and 14a of the main body 3 and the hooks 32 and 32 will be described. As shown in FIG. 1, the grip portion 34 has a shape extending diagonally upward and extending rearward (toward the center of the main body), and its lateral dimension is formed longer than the front-rear dimension. As shown in FIGS. 1 and 6, as described above, the grip portion 34 abuts on the convex portions 25 and 25 in the closed lid state and covers the concave portions 27 and 27 of the lid body 2 surrounded by the raised portions 21. Is placed in. As shown in FIG. 7A, in the closed state, the upper surface of the grip portion 34 has a shape in which the upper surface thereof is gently curved from the upper surface of the raised portion 21.

把持部３４の下端から連続する複数のフック３２、３２は、鉤状に形成されて、鉤の内側にヒンジ軸１４ａ、１４ａを当接して係合する。閉蓋状態では、フック３２の鉤口が外側を向いて、フック３２、３２とヒンジ軸１４ａ、１４ａとの係合状態が保持される。これは、フック３２、３２に係合されたヒンジ軸１４ａ、１４ａの軸抜け方向が図面上での上下方向であり、鉤口が図面上で左右方向であることから、ヒンジ軸１４ａ、１４ａの軸抜け方向をフック３２、３２が遮蔽している。 A plurality of hooks 32, 32 continuous from the lower end of the grip portion 34 are formed in a hook shape, and the hinge shafts 14a, 14a abut and engage with the inside of the hook. In the closed state, the hook mouth of the hook 32 faces outward, and the engaged state of the hooks 32, 32 and the hinge shafts 14a, 14a is maintained. This is because the hinge shafts 14a and 14a engaged with the hooks 32 and 32 are in the vertical direction on the drawing and the hooks are in the horizontal direction on the drawing. The hooks 32 and 32 shield the shaft pull-out direction.

一方、把持開閉体４は、図７（ａ）に示す閉蓋状態から、図７（ｂ）に示す開蓋状態へ上述した突起軸を軸心として回動することができる。この回動は、後述のストッパー３７により制止される位置まで約９０度、外側に向けて回動することで開蓋状態とする。この回動角度は、本実施形態では９０度の回動であるが、誤差を許容する範囲で略９０度としている。 On the other hand, the gripping opening / closing body 4 can rotate from the closed state shown in FIG. 7 (a) to the opened state shown in FIG. 7 (b) with the protrusion axis described above as an axis. This rotation is opened by rotating outward by about 90 degrees to a position stopped by the stopper 37 described later. This rotation angle is 90 degrees in the present embodiment, but is set to about 90 degrees within a range that allows an error.

この開蓋状態では、フック３２の鉤口が図面上下方を向いて、フック３２、３２とヒンジ軸１４ａ、１４ａとの係合状態が解除できる状態となる。これは、フック３２、３２に係合されたヒンジ軸１４ａ、１４ａの軸抜け方向が図面上での上下方向であり、鉤口が図面上で上下方向であることから、ヒンジ軸１４ａ、１４ａの軸抜け方向と鉤口の方向が一致している。そして、把持開閉体４の把持部３４を摘み、蓋体２を上方に押し上げれば、図２に示すように、フック３２の鉤口からヒンジ軸１４ａが外れて、把持開閉体４、４ごと蓋体２を開ける開蓋動作を行うことが可能になる。 In this open state, the hook mouth of the hook 32 faces downward in the drawing, and the engagement state between the hooks 32 and 32 and the hinge shafts 14a and 14a can be released. This is because the hinge shafts 14a and 14a engaged with the hooks 32 and 32 are in the vertical direction on the drawing and the hook mouth is in the vertical direction on the drawing. The direction of the shaft pulling out and the direction of the hook are the same. Then, when the grip portion 34 of the grip opening / closing body 4 is picked up and the lid body 2 is pushed upward, the hinge shaft 14a is disengaged from the hook opening of the hook 32 as shown in FIG. It becomes possible to perform a lid opening operation for opening the lid body 2.

把持部３４は、フック３２、３２の上端から鉛直方向に立ち上がり部３３、３３が形成され、この立ち上がり部３３、３３の上端から湾曲し、先端付近が水平方向になる。本実施形態において把持部３４は湾曲するものであるが、鉛直方向の立ち上がり部から曲げて水平方向となるようにすればよい。この把持部３４が折曲、湾曲しているため、把持開閉体４を回動した状態で、把持部３４の先端が上方を向く。さらに把持開閉体４の閉蓋状態で配置される蓋体２には凹部２７が形成され、把持部３４が湾曲する湾曲部分が形成されることから、この湾曲部分の内面側と蓋体２との間に所定の隙間Ｓが形成される。この隙間Ｓに使用者が指を挿入して把持開閉体４を摘み易くすることができる。 The grip portion 34 is formed with rising portions 33, 33 in the vertical direction from the upper ends of the hooks 32, 32, is curved from the upper ends of the rising portions 33, 33, and the vicinity of the tip is in the horizontal direction. In the present embodiment, the grip portion 34 is curved, but it may be bent from the rising portion in the vertical direction so as to be in the horizontal direction. Since the grip portion 34 is bent and curved, the tip of the grip portion 34 faces upward in a state where the grip opening / closing body 4 is rotated. Further, a recess 27 is formed in the lid 2 arranged in the closed state of the grip opening / closing body 4, and a curved portion in which the grip portion 34 is curved is formed. A predetermined gap S is formed between the two. The user can insert a finger into the gap S to facilitate the gripping opening / closing body 4.

つまり、使用者は把持部３４を指で起こして把持開閉体４を回動し、そのまま把持部３４を指で掴みながら上方に引っ張ることで、手を持ち替えずにワンタッチで蓋体２を開けることができる。そして、この隙間Ｓが形成されることで、小型の収納箱であっても使用者が容易に把持部３４を摘み、開閉させることが可能になる。 That is, the user raises the grip portion 34 with a finger to rotate the grip opening / closing body 4, and pulls the grip portion 34 upward while grasping the grip portion 34 with a finger, so that the lid body 2 can be opened with one touch without changing hands. Can be done. By forming this gap S, the user can easily pick and open the grip portion 34 even in a small storage box.

次に、把持開閉体４、４の係止、及び、過度な回動を抑制するストッパー３７について説明する。図１及び図８（ａ）、（ｂ）に示すように、本体３にはヒンジ軸１４ａ、１４ａと同軸状に並ぶ支持軸１５ａ、１５ａが形成されており、この支持軸１５ａ、１５ａに係合する被支持部２２、２２を一部切り欠いたガイド溝２３、２３にストッパー３７、３７が形成される。 Next, the stopper 37 that suppresses the locking and excessive rotation of the gripping opening / closing bodies 4 and 4 will be described. As shown in FIGS. 1 and 8 (a) and 8 (b), the main body 3 is formed with support shafts 15a and 15a coaxially arranged with the hinge shafts 14a and 14a, and is related to the support shafts 15a and 15a. Stoppers 37, 37 are formed in guide grooves 23, 23 in which the matching supported portions 22, 22 are partially cut out.

被支持部２２、２２は、蓋体２の凹部２７の外方端から連続して形成され、下方を鉤口とした鉤状に形成された筒状体としている。図８（ａ）に示すように、把持開閉体４とはストッパー３７を除いて干渉しておらず、把持開閉体４を回動し、開蓋状態にするときには下方に形成した鉤口から支持軸１５ａ、１５ａとの係合を解除することができる（図８（ｂ）参照）。また、他方の把持開閉体４を回動して開蓋状態とするときには、被支持部２２、２２の筒状体の内部で支持軸１５ａ、１５ａを軸心として蓋体２と一方の把持開閉体４とを回動することができる。 The supported portions 22 and 22 are formed in a hook shape formed continuously from the outer end of the recess 27 of the lid body 2 and have a hook opening at the lower side. As shown in FIG. 8A, the gripping opening / closing body 4 does not interfere with the gripping opening / closing body 4 except for the stopper 37, and when the gripping opening / closing body 4 is rotated to open the lid, it is supported from the hook opening formed below. The engagement with the shafts 15a and 15a can be released (see FIG. 8B). Further, when the other gripping / opening / closing body 4 is rotated to open the lid, the lid 2 and one of the gripping / opening / closing bodies are gripped / opened / closed with the support shafts 15a and 15a as the axes inside the tubular bodies of the supported portions 22 and 22. The body 4 can be rotated.

被支持部２２、２２には、図３、図８（ａ）、（ｂ）に示すように、被支持部２２の筒の円周方向に沿うように切り欠いた２つのガイド溝２３、２３を有し、このガイド溝２３、２３の下方側壁には下壁２３ａ、２３ａが形成される。下壁２３ａ、２３ａは、水平面となるように形成され、後述するストッパー３７、３７が係合した状態で、把持開閉体４、４が約９０度回動する位置で係止するように位置している。 As shown in FIGS. 3 and 8 (a) and 8 (b), the supported portions 22 and 22 have two guide grooves 23 and 23 notched along the circumferential direction of the cylinder of the supported portion 22. The lower walls 23a and 23a are formed on the lower side walls of the guide grooves 23 and 23. The lower walls 23a and 23a are formed so as to be horizontal, and are positioned so as to be locked at a position where the gripping opening / closing bodies 4 and 4 rotate about 90 degrees in a state where the stoppers 37 and 37 described later are engaged. ing.

一方、把持開閉体４は、把持部３４の湾曲部分の下縁から本体３の中央方向に延長したうえで下方に延長したストッパー３７、３７が形成されている。このストッパー３７、３７は、図８（ａ）に示すように、把持開閉体４の回動に伴いガイド溝２３内を摺動し、開蓋状態ではガイド溝２３、２３の下壁２３ａ、２３ａ、２３ａに係合する。 On the other hand, the grip opening / closing body 4 is formed with stoppers 37, 37 extending downward from the lower edge of the curved portion of the grip portion 34 toward the center of the main body 3. As shown in FIG. 8A, the stoppers 37, 37 slide in the guide groove 23 as the gripping opening / closing body 4 rotates, and the lower walls 23a, 23a of the guide grooves 23, 23 are in the opened state. , 23a.

ストッパー３７は、開蓋状態では下壁２３ａと係合するが、閉蓋状態で被支持部２２の内面壁に係合する。これにより、閉蓋状態への回動を抑止することができる。 The stopper 37 engages with the lower wall 23a in the opened state, but engages with the inner wall of the supported portion 22 in the closed state. Thereby, the rotation to the closed state can be suppressed.

次に、閉蓋状態を保持する機構について説明する。閉蓋状態を保持するためには、本実施形態では係止突起３５ａと被係止凹部２４ａとの係り止めにより行っている。 Next, the mechanism for holding the closed lid state will be described. In order to maintain the closed state, in the present embodiment, the locking projection 35a and the locked recess 24a are engaged with each other.

この開蓋状態の保持機構は、図１に示すように、開放部１６、１６（図４参照）の位置に、蓋体２から延長して形成される被支持部２２と略同一形状となる被係止部２４、２４と、この被係止部２４、２４の内側上面を一部凹ませた被係止凹部２４ａ、２４ａと、この位置に把持部３４の湾曲部分の下縁から本体３の中央方向に延長したうえで下方に延長して突出した係止突起３５ａ、３５ａとからなる。閉蓋状態ではこの係止突起３５ａ、３５ａが被係止凹部２４ａ、２４ａに嵌まり込んで、閉蓋状態が係止、保持され、開蓋状態とするときには、把持開閉体４、４を回動すると、係止突起３５ａ、３５ａと被係止凹部２４ａ、２４ａとの係止が解除される。 As shown in FIG. 1, the holding mechanism in the opened state has substantially the same shape as the supported portion 22 formed by extending from the lid 2 at the positions of the open portions 16 and 16 (see FIG. 4). The locked portions 24, 24, the locked recesses 24a, 24a in which the inner upper surface of the locked portions 24, 24 is partially recessed, and the main body 3 at this position from the lower edge of the curved portion of the grip portion 34. It is composed of locking projections 35a and 35a which are extended in the central direction and then extended downward. In the closed state, the locking projections 35a and 35a are fitted into the locked recesses 24a and 24a, and when the closed state is locked and held and the lid is opened, the gripping opening / closing bodies 4 and 4 are rotated. When moved, the locking projections 35a and 35a and the locked recesses 24a and 24a are released from locking.
