Further, columnar protrusions 34, 34 extending outward in the left-right direction protrude from the outer surfaces of the side walls 33a, 33b, respectively. The protrusions 34 are arranged coaxially with respect to an axis extending in the left-right direction.
ドア蓋30の材質は特に限定されないが、軽量性、強度、耐腐食性等の観点から、ゴム弾性を有さない硬質の合成樹脂から構成されることが好ましい。本実施形態では、ドア蓋30は、飽和ポリエステル製である。また、本実施形態では、ドア蓋30は、後述する第1延在部50とともに一体的に構成されている。 Although the material of the door lid 30 is not particularly limited, it is preferably made of a hard synthetic resin that does not have rubber elasticity from the viewpoint of lightness, strength, corrosion resistance, and the like. In the present embodiment, the door lid 30 is made of saturated polyester. In the present embodiment, the door lid 30 is configured integrally with a first extending portion 50 described later.
一方、フレーム40は、概ね円環状のベースフレーム41と、ベースフレーム41の後部からさらに背面側へ延びる左右一対の側壁部42a,42bとを有する。側壁部42a,42bの下部は、同じくベースフレーム41の後部からさらに背面側へ延びる下面部43(図7及び図8参照)を介して接続されている。また、側壁部42a,42bには、それぞれ孔44,44が形成されている。孔44,44は、左右方向に延びる軸線に対し同軸に配置されている。 On the other hand, the frame 40 includes a generally annular base frame 41 and a pair of left and right side wall portions 42a and 42b extending further from the rear portion of the base frame 41 to the back side. Similarly, the lower portions of the side wall portions 42a and 42b are connected via a lower surface portion 43 (see FIGS. 7 and 8) extending further from the rear portion of the base frame 41 to the back surface side. Further, holes 44 and 44 are formed in the side wall portions 42a and 42b, respectively. The holes 44 are arranged coaxially with respect to an axis extending in the left-right direction.
フレーム40の材質は特に限定されないが、軽量性、強度、耐腐食性等の観点から、ゴム弾性を有さない硬質の合成樹脂から構成されることが好ましい。本実施形態では、フレーム40は、ポリプロピレン製である。また、本実施形態では、フレーム40は、後述する第2延在部60とともに一体的に構成されている。 Although the material of the frame 40 is not particularly limited, it is preferably made of a hard synthetic resin that does not have rubber elasticity from the viewpoint of lightness, strength, corrosion resistance, and the like. In the present embodiment, the frame 40 is made of polypropylene. In the present embodiment, the frame 40 is integrally configured with a second extending portion 60 described later.
ドア蓋30の側壁部33a,33bは、それぞれ側壁部33a,33bの外面がフレーム40の側壁部42a,42bの内面に対向するように、側壁部42a,42bの間に配置されている。また、ドア蓋30の突起34,34は、それぞれ側壁部42a,42bの孔44,44内に挿入されている。このため、突起34,34は、ドア蓋30とフレーム40とを連結するヒンジ機構4の回動軸を形成し、孔44,44は、この回動軸を受け取る軸受を形成する。すなわち、板部材32、側壁部33a,33b、突起34,34、側壁部42a,42b、孔44,44及び下面部43により、ヒンジ機構4が形成されている。これにより、ドア蓋30は、フレーム40に対しヒンジ式に連結され、フレーム40に対し回動可能となる。蓋本体31の周縁部は、閉状態においてベースフレーム41の上端部41bに受け取られ(ただし、図2に示すように、両者の間には若干の隙間が存在する)、このとき、蓋本体31が開口S1を上部から覆う。 The side wall portions 33a and 33b of the door lid 30 are disposed between the side wall portions 42a and 42b so that the outer surfaces of the side wall portions 33a and 33b face the inner surfaces of the side wall portions 42a and 42b of the frame 40, respectively. Further, the projections 34, 34 of the door lid 30 are inserted into the holes 44, 44 of the side wall portions 42a, 42b, respectively. For this reason, the projections 34 and 34 form a rotation shaft of the hinge mechanism 4 that connects the door lid 30 and the frame 40, and the holes 44 and 44 form a bearing that receives the rotation shaft. That is, the hinge mechanism 4 is formed by the plate member 32, the side wall portions 33a and 33b, the protrusions 34 and 34, the side wall portions 42a and 42b, the holes 44 and 44, and the lower surface portion 43. Thereby, the door lid 30 is hingedly connected to the frame 40 and can be rotated with respect to the frame 40. The peripheral edge of the lid body 31 is received by the upper end 41b of the base frame 41 in the closed state (however, as shown in FIG. 2, there is a slight gap between them). At this time, the lid body 31 Covers the opening S1 from above.
図4〜図6に示すように、ベースフレーム41は、概ね厚みが一定の周壁部41aを有する。周壁部41aの内周面には、周方向に沿って延びるリブ45が形成されている。より具体的には、リブ45は、周壁部41aの中心軸に沿って螺旋状に延びており、前述した口部24に形成されるリブ25と螺号する。 As shown in FIGS. 4-6, the base frame 41 has the surrounding wall part 41a with substantially constant thickness. Ribs 45 extending along the circumferential direction are formed on the inner peripheral surface of the peripheral wall portion 41a. More specifically, the rib 45 extends spirally along the central axis of the peripheral wall portion 41a and is screwed with the rib 25 formed in the mouth portion 24 described above.
ベースフレーム41の上端部41bは、周壁部41aの上部に位置し、周壁部41aの内周面よりも内側に突出している。すなわち、ベースフレーム41の上部には、ベースフレーム41の内側から見て、段差が形成されている。そして、この段差に引っ掛けられるようにして、ベースフレーム41には円環状のガスケット70が取り付けられている。 The upper end portion 41b of the base frame 41 is located on the upper portion of the peripheral wall portion 41a and protrudes inward from the inner peripheral surface of the peripheral wall portion 41a. That is, a step is formed in the upper part of the base frame 41 when viewed from the inside of the base frame 41. An annular gasket 70 is attached to the base frame 41 so as to be caught by the step.
図4〜図6に示すように、ガスケット70は、円環状の本体部71と、本体部71の上面の中央付近から上方に延びる円環状の上部72とを有する。本体部71は、縦断面が概ね矩形状である。また、ガスケット70は、本体部71の径方向の内側端から下方に延びる円環状の内側下部73と、本体部71の径方向の外側端から下方に延びる円環状の外側下部74とを有する。図5及び図6に示すように、本体部71と上部72とにより形成される段差(径方向外側に面する段差)は、ベースフレーム41の上端部41bと周壁部41aとにより形成される段差とかみ合うように配置され、噛合面が互いにしっかりと接触する。また、本体部71及び外側下部74の外周面は、周壁部41aの内周面にしっかりと接触する。また、フレーム40が容器本体2に取り付けられた状態で、本体部71の下面は、容器本体2の口部24の上端部にしっかりと接触する。このようにガスケット70は、フレーム40が容器本体2に取り付けられた状態で口部24とベースフレーム41との間に形成される隙間に挟まれ、当該隙間を埋め、当該隙間をシールする。 As shown in FIGS. 4 to 6, the gasket 70 includes an annular main body 71 and an annular upper portion 72 extending upward from the vicinity of the center of the upper surface of the main body 71. The main body 71 has a substantially rectangular longitudinal section. The gasket 70 has an annular inner lower portion 73 that extends downward from the radially inner end of the main body 71 and an annular outer lower portion 74 that extends downward from the radial outer end of the main body 71. As shown in FIGS. 5 and 6, the step formed by the main body portion 71 and the upper portion 72 (step facing outward in the radial direction) is the step formed by the upper end portion 41 b of the base frame 41 and the peripheral wall portion 41 a. The meshing surfaces are in close contact with each other. Further, the outer peripheral surfaces of the main body 71 and the outer lower portion 74 are in firm contact with the inner peripheral surface of the peripheral wall portion 41a. In addition, in a state where the frame 40 is attached to the container main body 2, the lower surface of the main body portion 71 firmly contacts the upper end portion of the mouth portion 24 of the container main body 2. As described above, the gasket 70 is sandwiched between the gaps formed between the mouth portion 24 and the base frame 41 in a state where the frame 40 is attached to the container body 2, filling the gaps, and sealing the gaps.
また、図6に示すように、ガスケット70は、ドア蓋30が閉位置にあるときにベースフレーム41とドア蓋30との隙間に挟まれ、当該隙間をシールする。より具体的には、ドア蓋30は、蓋本体31の下面から垂下する円環状の脚部35を有する。脚部35は、蓋本体31の外周縁のやや内側に位置する。そして、閉状態においては、本体部71と上部72とにより形成される段差(径方向内側に面する段差)は、蓋本体31と脚部35とにより形成される段差(径方向外側に面する段差)とかみ合い、噛合面が互いにしっかりと接触する。 As shown in FIG. 6, the gasket 70 is sandwiched between the base frame 41 and the door lid 30 when the door lid 30 is in the closed position, and seals the gap. More specifically, the door lid 30 has an annular leg portion 35 that hangs down from the lower surface of the lid body 31. The leg portion 35 is located slightly inside the outer peripheral edge of the lid main body 31. In the closed state, a step formed by the main body portion 71 and the upper portion 72 (step facing inward in the radial direction) is formed by a step formed in the lid main body 31 and the leg portion 35 (facing outward in the radial direction). Step) and the meshing surfaces are in good contact with each other.
以上の構成のガスケット70により、ドア蓋30が閉位置にあるときに開口S1が完全に閉じられ、容器本体2の内部空間S2が外部から密閉される。また、本実施形態では、1つのガスケット70が、フレーム40とドア蓋30との隙間に加え、容器本体2とフレーム40との隙間をシールする。従って、部品点数が少なく、シンプルな構造でありながら、密閉性の高い容器1が実現される。 With the gasket 70 having the above configuration, the opening S1 is completely closed when the door lid 30 is in the closed position, and the internal space S2 of the container body 2 is sealed from the outside. In the present embodiment, one gasket 70 seals the gap between the container body 2 and the frame 40 in addition to the gap between the frame 40 and the door lid 30. Therefore, the container 1 having a high hermeticity can be realized with a simple structure with a small number of parts.
図4、図7及び図8に示すとおり、キャップ3は、ドア蓋30を閉位置に維持するためのロック機構5を有する。ロック機構5は、蓋本体31から延在する第1延在部50と、ベースフレーム41から延在する第2延在部60とから構成される。第1延在部50は、蓋本体31の前部からやや正面側へ突出した突出部51と、突出部51の正面側から下方へ延びる板部材52とを有する。板部材52の正面には、左右方向の中央付近に爪53が形成されている。一方、第2延在部60は、ベースフレーム41の前部からやや正面側へ突出した突出部61と、突出部61から上方へ延びる板部材62とを有する。また、第2延在部60は、板部材62の上端に連続する押しボタン63を有する。押しボタン63の背面には、左右方向の中央付近に爪64が形成されている。また、第2延在部60は、ベースフレーム41の前部に連続し、以上の部61〜64を囲む周壁部65を有する。周壁部65は、これらの部61〜64と干渉しない位置に配置されている。 As shown in FIGS. 4, 7, and 8, the cap 3 includes a lock mechanism 5 for maintaining the door lid 30 in the closed position. The lock mechanism 5 includes a first extending portion 50 that extends from the lid body 31 and a second extending portion 60 that extends from the base frame 41. The first extending portion 50 includes a protruding portion 51 that protrudes slightly from the front portion of the lid main body 31 toward the front side, and a plate member 52 that extends downward from the front side of the protruding portion 51. On the front surface of the plate member 52, a claw 53 is formed near the center in the left-right direction. On the other hand, the second extending portion 60 includes a protruding portion 61 protruding slightly from the front portion of the base frame 41 to the front side, and a plate member 62 extending upward from the protruding portion 61. The second extending portion 60 has a push button 63 that is continuous with the upper end of the plate member 62. On the back surface of the push button 63, a claw 64 is formed near the center in the left-right direction. The second extending portion 60 has a peripheral wall portion 65 that is continuous with the front portion of the base frame 41 and surrounds the above portions 61 to 64. The peripheral wall portion 65 is disposed at a position that does not interfere with these portions 61 to 64.
ドア蓋30が開位置から前方へ倒れ、閉位置に近づくと、板部材52は、板部材62とベースフレーム41との間の空間に挿入される。このとき、爪53が爪64を押し、これにより板部材62が弾性変形しやや前方へ倒れる。そして、この状態から板部材52がさらに深くまで進むと、爪53が爪64を乗越える。このとき、板部材62が弾性力により元の位置に復帰し、両爪64,53が互いにかみ合う。これにより、爪53が爪64に引っ掛かり、ドア蓋30が閉位置に維持されるロック状態が形成される。 When the door lid 30 falls forward from the open position and approaches the closed position, the plate member 52 is inserted into the space between the plate member 62 and the base frame 41. At this time, the claw 53 pushes the claw 64, whereby the plate member 62 is elastically deformed and falls slightly forward. Then, when the plate member 52 advances further from this state, the claw 53 gets over the claw 64. At this time, the plate member 62 is returned to the original position by the elastic force, and the claws 64 and 53 engage with each other. Thereby, the nail | claw 53 is hooked on the nail | claw 64 and the locked state in which the door cover 30 is maintained in a closed position is formed.
ロック状態で使用者が押しボタン63を指で押圧すると、再び板部材62が弾性変形してやや前方へ倒れる。これにより、爪53と爪64とがかみ合みあったロック状態が解除され、解除状態となる。以上のとおり、ロック機構5は、ロック状態と解除状態とを切り替えることができる。 When the user presses the push button 63 with a finger in the locked state, the plate member 62 is elastically deformed again and falls slightly forward. Thereby, the locked state in which the nail | claw 53 and the nail | claw 64 meshed is cancelled | released, and it will be in a cancellation | release state. As described above, the lock mechanism 5 can switch between the locked state and the released state.
ロック状態が解除されると、ドア蓋30は回動軸34周りを自動的に回動し、開位置に復帰する。より具体的には、キャップ3は、図4、図7及び図8に示すとおり、上述したヒンジ機構4と協働する付勢部材80をさらに有している。付勢部材80は、ドア蓋30を開位置に向かう方向に付勢する。なお、本実施形態では、ドア蓋30は開位置にあるときに概ね上下方向に起立する。 When the locked state is released, the door lid 30 automatically rotates around the rotation shaft 34 and returns to the open position. More specifically, the cap 3 further includes a biasing member 80 that cooperates with the hinge mechanism 4 described above, as shown in FIGS. 4, 7, and 8. The urging member 80 urges the door lid 30 in the direction toward the open position. In the present embodiment, the door lid 30 rises up and down substantially when in the open position.
付勢部材80は、ガスケット70と同じ材料からなり、ガスケット70と一体的に構成されている。付勢部材80及びガスケット70は、弾性材料からなり、ゴム弾性を有する。付勢部材80及びガスケット70は、典型的にはエラストマー(ゴム又は熱可塑性エラストマー)から構成され、本実施形態では、シリコーンゴム製である。ガスケット70及び付勢部材80は、柔らかく変形が容易であるため、キャップ2のその他の部位から取り外すことができる。 The urging member 80 is made of the same material as the gasket 70 and is configured integrally with the gasket 70. The urging member 80 and the gasket 70 are made of an elastic material and have rubber elasticity. The biasing member 80 and the gasket 70 are typically made of an elastomer (rubber or thermoplastic elastomer), and are made of silicone rubber in this embodiment. Since the gasket 70 and the urging member 80 are soft and easily deformed, they can be removed from other parts of the cap 2.
付勢部材80は、ガスケット70の後部に連続しており、ガスケット70の後部からやや背面側へ突出した突出部81を有する。なお、図4に示すとおり、ベースフレーム41の上端部41b及び周壁部41aの上部は概ね全周に亘って延びているが、後部において一部が切り欠かれている。突出部81は、この切り欠きを通り、ベースフレーム41の径方向内側から外側に達する。 The urging member 80 is continuous with the rear portion of the gasket 70 and has a protruding portion 81 protruding slightly from the rear portion of the gasket 70 toward the back side. In addition, as shown in FIG. 4, although the upper end part 41b of the base frame 41 and the upper part of the surrounding wall part 41a are extended over the perimeter, a part is notched in the rear part. The protruding portion 81 passes through the notch and reaches from the radially inner side to the outer side of the base frame 41.
図7及び図8に示すように、付勢部材80は、突出部81の後部から下方に延びる壁部82と、壁部82の下部から折れ曲がって後方へ延びるシート部83とをさらに有する。壁部82の径方向の内側面は、ベースフレーム41の外周面にしっかりと接触する。一方、シート部83の外面は、ベースフレーム41から後方へ延びる下面部43の上面と、蓋本体31から後方へ延びる板部材32の内面とにしっかりと接触する。板部材32の内面には、突起36が形成されている。一方、シート部83は概ね矩形であるが、その先端部には、突起36を受け取るための切り欠きが形成されている。そして、この切り欠きに突起36が挿入されることにより、シート部83の位置が固定される。この状態で、シート部83は突起36にしっかりと接触する。 As shown in FIGS. 7 and 8, the biasing member 80 further includes a wall portion 82 that extends downward from the rear portion of the protruding portion 81, and a seat portion 83 that is bent from the lower portion of the wall portion 82 and extends rearward. The inner surface in the radial direction of the wall portion 82 is in firm contact with the outer peripheral surface of the base frame 41. On the other hand, the outer surface of the seat portion 83 firmly contacts the upper surface of the lower surface portion 43 extending rearward from the base frame 41 and the inner surface of the plate member 32 extending rearward from the lid body 31. A projection 36 is formed on the inner surface of the plate member 32. On the other hand, the sheet portion 83 is generally rectangular, but a notch for receiving the projection 36 is formed at the tip thereof. And the position of the sheet | seat part 83 is fixed by inserting the protrusion 36 in this notch. In this state, the sheet portion 83 is in firm contact with the protrusion 36.
図8に示すとおり、シート部83は、ドア蓋30が閉位置にあるときに、板部材32と下面部43との間の空間に折り畳まれて収容される。しかしながら、ロック状態が解除されると、折り畳まれていたシート部83は、元のより平らな形状に戻ろうとする弾性力により板部材32を押す。これにより、板部材32に連結されている蓋本体31が開く方向に自動的に回動する。以上のとおり、容器1は、押しボタン63を押すだけでドア蓋30を開くことができるワンプッシュオープン式に構成されており、操作性に優れている。なお、ドア蓋30が所定の角度まで回動すると、ドア蓋30の側壁部33a,33bがフレーム40の下面部43に接触し、それ以上の回転が規制される。 As shown in FIG. 8, the seat portion 83 is folded and accommodated in a space between the plate member 32 and the lower surface portion 43 when the door lid 30 is in the closed position. However, when the locked state is released, the folded sheet portion 83 pushes the plate member 32 by an elastic force to return to the original flatter shape. Thereby, the lid body 31 connected to the plate member 32 automatically rotates in the opening direction. As described above, the container 1 is configured in a one-push open type in which the door lid 30 can be opened only by pressing the push button 63, and is excellent in operability. When the door lid 30 is rotated to a predetermined angle, the side wall portions 33a and 33b of the door lid 30 come into contact with the lower surface portion 43 of the frame 40, and further rotation is restricted.
シート部83は、ガスケット70及び付勢部材80がキャップ3の他の部分から取り外された状態では平板状である。そして、シート部83は、閉状態において折り畳まれているときのみならず、図7に示すとおり開状態においても湾曲している。そのため、付勢部材80は、ドア蓋30に対し開状態においてもドア蓋30をさらに開く方向に力を加えている。従って、例えば、使用時に容器1を傾ける等しても、ドア蓋30が自重により倒れ難い。よって、使用時にドア蓋30が大きくパタパタと揺れることがなく、容器1は使い勝手に優れている。 The seat portion 83 has a flat plate shape when the gasket 70 and the biasing member 80 are removed from the other portions of the cap 3. And the sheet | seat part 83 is curved not only when folded in the closed state but also in the open state as shown in FIG. Therefore, the urging member 80 applies a force to the door lid 30 in the direction of further opening the door lid 30 even in the open state. Therefore, for example, even if the container 1 is tilted during use, the door lid 30 is unlikely to fall down due to its own weight. Therefore, the door lid 30 is not greatly shaken during use, and the container 1 is excellent in usability.
また、図4、図7及び図8に示すとおり、シート部83の内面上には、部分的に肉厚部84が形成されている。この肉厚部84は、シート部83が元の形状に戻ろうとする弾性力を高めることができる。また、この肉厚部84は、シート部83が開状態及び閉状態並びにこれら状態の間の状態において、常に同様の形状に変形することを助長する。従って、常に同じような開状態及び閉状態を実現することができる。 As shown in FIGS. 4, 7, and 8, a thick portion 84 is partially formed on the inner surface of the sheet portion 83. This thick portion 84 can increase the elastic force of the sheet portion 83 trying to return to its original shape. In addition, the thick portion 84 helps the sheet portion 83 to always be deformed into the same shape in the open state, the closed state, and the state between these states. Therefore, the same open state and closed state can always be realized.
