Description
本考案は、筆入れなどのプラスチックケースの開閉蓋口止め部の構造の改良に 関するものである。 The present invention relates to the improvement of the structure of the opening / closing lid stopper part of a plastic case such as a pencil case.
【０００２】[0002]
プラスチック製の筆入れ等のケースに見られるように、底函に開閉自在に取付 けた蓋体を閉鎖するための口止め部は、従来、例えば図７と図８に示す構造を採 る。 As seen in a case such as a plastic pencil case, a mouth stop portion for closing a lid which is openably and closably attached to a bottom box has conventionally a structure shown in FIGS. 7 and 8, for example.
【０００３】 即ち、底函Ａの正面側壁Ｃのほぼ中央に開口Ｄが形成され、この開口Ｄに近接 する底板Ｂの適所に閉鎖片Ｅの基部Ｆを固定する凹所Ｇが設けられている。閉鎖 片Ｅはプラスチック等の撓み弾性を有する素材によって形成され、上記凹所Ｇに 嵌着される基部Ｆと、この基部Ｆの一端から屈曲部Ｈを介してほぼ垂直に立上っ た起立部Ｉとを備え、起立部Ｉが前倒れする方向に付勢力を有する。起立部Ｉは 前面の高さ方向ほぼ中央に操作用舌片Ｊが突出形成され、前面上端には前方に僅 かに突出する係止部Ｋが形成されている。操作用舌片Ｊは、上記した基部Ｆを凹 所Ｇに嵌着させたときに前記開口Ｄに入り込み、その先端ｊが底函Ａの正面側壁 Ｃから突出する長さを有する。That is, an opening D is formed substantially in the center of the front side wall C of the bottom box A, and a recess G for fixing the base portion F of the closing piece E is provided at an appropriate position on the bottom plate B near the opening D. . The closing piece E is formed of a flexible elastic material such as plastic and has a base portion F fitted into the recess G and an upright portion which rises from one end of the base portion F through a bent portion H in a substantially vertical manner. I, and has a biasing force in a direction in which the upright portion I tilts forward. In the upright portion I, an operating tongue J is formed to project substantially at the center of the front surface in the height direction, and a locking portion K slightly projecting forward is formed at the upper end of the front surface. The operating tongue J has a length such that when the base F is fitted into the recess G, the operating tongue J enters the opening D, and the tip j thereof projects from the front side wall C of the bottom box A.
【０００４】 底函Ａの図示しない背面壁とヒンジを介して開閉自在に取付けられた蓋体Ｌは 、その正面壁Ｍの内面に、閉鎖片Ｅの上記係止部Ｋを保持して蓋体Ｌを閉状態を 保つ保持溝Ｎが設けられている。The lid L attached to the rear wall (not shown) of the bottom box A via a hinge so as to be openable and closable is such that the lid L holds the locking portion K of the closing piece E on the inner surface of the front wall M thereof. A holding groove N for keeping L closed is provided.
【０００５】 従って、従来のこの口止め部では、両図に示す閉蓋状態で、操作用舌片Ｊの先 端ｊを押すと、起立部Ｉが屈曲部Ｈの上端を支点としてケース内方に撓み、係止 部Ｋが保持溝Ｎから外れて蓋体Ｌは開放可能となる。操作用舌片Ｊの先端ｊの押 圧力をとくと、起立部Ｉが弾性復帰して係止部Ｋを閉じられた蓋体Ｌの保持溝Ｎ に係止させてロックする。Therefore, in this conventional mouth stopper, when the tip end j of the operating tongue J is pushed in the closed state shown in both figures, the upright portion I moves inward of the case with the upper end of the bent portion H as a fulcrum. The bending and locking portion K is disengaged from the holding groove N, and the lid L can be opened. When the pressing force of the tip j of the operating tongue J is released, the upright portion I elastically returns and the locking portion K is locked by locking the holding groove N 1 of the closed lid L.
【０００６】[0006]
ところが、こうした構造では開口Ｄと保持溝Ｎが底函Ａと蓋体Ｌに個別に形成 される関係上、操作用舌片Ｊと係止部Ｋとの間にある程度の間隔をとらざるを得 ない。また、閉鎖片の起立部Ｉは、蓋体Ｌが閉じられているとき、係止部Ｋと保 持溝Ｎとが容易に離脱しないような撓み弾性を必要とする。このため、この口止 め部を筆入れに適用すると、小学生低学年の児童などの場合には楽に開蓋するこ とができないことがある。 However, in such a structure, since the opening D and the holding groove N are individually formed in the bottom box A and the lid L, a certain distance must be provided between the operating tongue J and the locking portion K. Absent. Further, the upright portion I of the closing piece needs to have a bending elasticity so that the locking portion K and the holding groove N are not easily separated when the lid L is closed. For this reason, if this mouthpiece is applied to a brush case, it may not be possible to easily open the lid for children in the lower grades of elementary school.
【０００７】 また、操作用舌片Ｊは前倒れ方向に付勢力を有し、操作用舌片Ｊを押しても蓋 体自体は単に内部のロックが外れた状態にあるすぎない。このため、上記構造の 口止め部では、片手で操作用舌片Ｊを押しながら他方の手で蓋体Ｌを開いてやら なければならず、押す動作と開く動作がそれぞれ別個の手で片手操作されるため に上記した低学年児童ではなおさら操作しにくくなる。Further, the operating tongue J has a biasing force in the forward tilting direction, and even if the operating tongue J is pushed, the lid itself is merely in a state where the internal lock is unlocked. For this reason, in the mouth stop portion of the above structure, it is necessary to open the lid L with the other hand while pressing the operating tongue J with one hand, and the pushing operation and the opening operation are operated by one hand respectively. Therefore, it becomes more difficult for the lower grade children mentioned above to operate.
【０００８】 本考案の目的は、上記した従来技術の問題点に鑑み、閉蓋状態においては従来 と同様の付勢力でしっかりと蓋を閉止できる一方、開蓋時には比較的楽な操作で 蓋体を開けることのできる、プラスチックケースの口止め部の構造を提供するこ とにある。In view of the above-mentioned problems of the prior art, an object of the present invention is to close the lid firmly with the same urging force as in the conventional state in the closed state, while the lid body is relatively easy to operate when the lid is opened. The purpose of the present invention is to provide a structure for a mouth stop of a plastic case that can be opened.
【０００９】[0009]
本考案は上記した目的を達成するために、底函と開閉自在な蓋体とを有し、撓 み弾性を有する閉鎖片を上記底函と蓋体の正面壁内面に跨るようにして取り付け 、この閉鎖片の上部に設けた係止部を蓋体内面に弾性的に係止させて蓋体を閉鎖 する一方、ケース外部に突出した閉鎖片の操作用舌片を押すことにより、閉鎖片 をケース内方に撓ませると共に上記係止状態を解除して蓋体を開放させる、プラ スチックケースの口止め部の構造において、次の構成を採用した点に特徴がある 。 In order to achieve the above-mentioned object, the present invention has a bottom box and a lid that can be opened and closed, and attaches a flexible elastic closing piece so as to straddle the bottom box and the inner surface of the front wall of the lid. The locking part provided on the upper part of the closing piece is elastically locked to the inner surface of the lid to close the lid, while the operating tongue of the closing piece protruding outside the case is pushed to open the closing piece. The structure of the mouth-stop portion of the plastic case that bends inwardly of the case and releases the locked state to open the lid is characterized by adopting the following configuration.
【００１０】 即ち、底函の正面壁上端あるいは蓋体の正面壁下端に閉鎖片の操作用舌片を受 け入れる切欠き部を形成する。この切欠き部に近接した蓋体の正面壁内面に閉鎖 片の上記係止状態を確保するための被係止部を設ける。底函の正面壁上端に切欠 き部を形成した場合には、操作用舌片の上面が閉じられた蓋体の正面壁下端にほ ぼ接触する。また、蓋体の正面壁下端に切欠き部を形成した場合には、操作用舌 片の上面が切欠き部の上縁にほぼ接触する。That is, a notch is formed at the upper end of the front wall of the bottom box or the lower end of the front wall of the lid to receive the operating tongue of the closing piece. A locked portion is provided on the inner surface of the front wall of the lid near the notch to secure the locked state of the closing piece. When the notch is formed at the upper end of the front wall of the bottom box, the upper surface of the operating tongue almost comes into contact with the lower end of the front wall of the closed lid. Further, when the notch is formed at the lower end of the front wall of the lid, the upper surface of the operating tongue almost contacts the upper edge of the notch.
【００１１】 また、この構造において、上記した閉鎖片の操作用舌片よりも下方に位置する 面上に突片を設け、この突片と対応する位置の底函正面壁に開口を形成し、突片 を開口に嵌入させて閉鎖片をケース内側に固定するようにしても良い。Further, in this structure, a projecting piece is provided on the surface of the above-mentioned closing piece located below the operating tongue piece, and an opening is formed in the front wall of the bottom box at a position corresponding to this projecting piece. It is also possible to fit the projecting piece into the opening and fix the closing piece inside the case.
【００１２】 さらに、閉鎖片は、前記底函の底板に固定される基部と、底函及び蓋体の正面 壁内面にほぼ当接される立上がり部とを有し、基部と立上がり部との境の屈曲部 を内方に湾曲した形状とすることもできる。Further, the closing piece has a base portion fixed to the bottom plate of the bottom box, and a rising portion that substantially abuts against the inner surface of the front wall of the bottom box and the lid, and the boundary between the base portion and the rising portion. It is also possible to make the bent part of the inwardly curved shape.
【００１３】[0013]
この口止め部は、操作用舌片が切欠き部に受け入れられるので、係止部に可及 的に近い位置、即ち閉鎖片の撓み支点である屈曲部からより遠い位置に操作用舌 片が設けられることとなる。このため、従来よりも小さな力で操作用舌片を押す ことにより、係止部が被係止部から離脱される。 In this mouth stop, the operating tongue is received in the notch, so that the operating tongue is provided at a position as close as possible to the locking part, that is, at a position farther from the bending part which is the bending fulcrum of the closing piece. Will be done. Therefore, the locking portion is released from the locked portion by pushing the operating tongue piece with a force smaller than the conventional force.
【００１４】 操作用舌片を押すと、係止部が被係止部から離脱されるだけでなく、蓋体の正 面壁下端あるいは正面壁に形成された切欠き部の上縁が舌片の上面によって持ち 上げられて蓋体が自動的に若干開くので、開蓋操作をし易い。When the operating tongue is pushed, not only the locking portion is disengaged from the locked portion, but also the upper edge of the notch formed in the lower end of the front wall or the front wall of the lid body is the tongue piece. The lid is lifted by the top surface and the lid opens automatically slightly, making it easy to open the lid.

以下、本考案を図示した実施例に基づいて詳説する。 図１及び図２は本考案の一実施例に係る口止め部を備えたプラスチック製筆入 れの外観斜視図とその断面図である。 Hereinafter, the present invention will be described in detail based on illustrated embodiments. 1 and 2 are an external perspective view and a cross-sectional view of a plastic pencil case having a stopper according to an embodiment of the present invention.
【００１６】 図中符号１は上記筆入れを構成する底函で、その起立する背面壁１ｃの上端に ヒンジ２を介して（図２参照）函状の蓋体３が開閉自在に取り付けられている。 ４は底函１と蓋体３とを筆入れ正面の口止め部において連結する閉鎖片で、プラ スチックなどの撓み弾性を有する素材によって後述する形状に形成されている。In the figure, reference numeral 1 is a bottom box which constitutes the above-mentioned brush case, and a box-shaped lid body 3 is attached to the upper end of the rear wall 1c which stands upright via a hinge 2 (see FIG. 2) so as to be openable and closable. There is. Reference numeral 4 denotes a closing piece that connects the bottom box 1 and the lid body 3 at a mouth stop on the front side of the writing case, and is formed in a shape described later by a flexible elastic material such as plastic.
【００１７】 １ａは底函１の正面壁で、その上端適所に切欠き部５が設けられ、この切欠き 部５の下方には壁面をくりぬいた開口６が形成されている。また、底函１の底板 １ｂであってこられ切欠き部５と開口６に近接する位置には凹所７が形成されて いる。Reference numeral 1a is a front wall of the bottom box 1, a notch portion 5 is provided at an appropriate position on the upper end thereof, and an opening 6 having a hollowed wall surface is formed below the notch portion 5. A recess 7 is formed in the bottom plate 1b of the bottom box 1 at a position close to the notch 5 and the opening 6.
【００１８】 一方、蓋体３は、その立ち下がった正面壁３ａの内面であって底函１の上記切 欠き部５に接近した位置に係止用溝８が設けられている。On the other hand, the lid 3 is provided with a locking groove 8 on the inner surface of the lowered front wall 3 a and at a position close to the cutout portion 5 of the bottom box 1.
【００１９】 閉鎖片４は、従来例と同様に、上記凹所７に嵌着される基部４ａと、この基部 ４ａの一側端から屈曲部４ｂを経て立ち上がると共に上端に前方に突出する係止 突起９を備えた立上がり部４ｃとを有する。立上がり部４は、後方に押されたと きに前方に倒れ込む方向に撓み弾性による付勢力を有する。閉鎖片４は、係止突 起９の直下に上記切欠き部５に受け入れられる操作用舌片１０が設けられている 。蓋体３の係止用溝３ａと底函１の切欠き部５とが接近した位置に設けれられる ことから、従来の閉鎖片と異なり、係止突起９と操作用舌片１０とが可及的に近 接した位置にある。Similar to the conventional example, the closing piece 4 has a base portion 4a fitted into the recess 7 and a locking portion that stands up from one side end of the base portion 4a via a bent portion 4b and projects forward to the upper end. It has a rising portion 4c having a protrusion 9. The rising portion 4 has a biasing force due to elastic bending in a direction in which the rising portion 4 falls forward when pushed backward. The closing piece 4 is provided with an operating tongue piece 10 that is received in the notch 5 just below the locking protrusion 9. Since the locking groove 3a of the lid 3 and the notch 5 of the bottom box 1 are provided in close proximity to each other, unlike the conventional closing piece, the locking projection 9 and the operating tongue piece 10 are possible. It is located as close as possible.
【００２０】 操作用舌片１０の下方には上記した開口６に挿入される浮上がり防止片１１が 突設されている。また、屈曲部４ｂは基部４ａと立上がり部４ｃの内方に湾曲さ れている。Below the operation tongue piece 10, a rising prevention piece 11 that is inserted into the opening 6 is provided in a protruding manner. The bent portion 4b is curved inward of the base portion 4a and the rising portion 4c.
【００２１】 そして、この閉鎖片４は、基部４ａを底板１ｃの凹所７に嵌め込み、立上がり 部正面の浮上がり防止片１１を底函正面壁１ａの開口６に挿入し、操作用舌片１ ０を同正面壁１ａの切欠き部５に受け入れさせて底函内面に取り付けられる。こ の状態で、蓋体３を閉じると、蓋体３の正面壁下端部内面に沿って係止突起３ａ が押され、閉鎖片４の立上がり部４ｃが後方に撓んだ後、係止用溝部８に係止突 起９が入り込んで蓋体３を底函１にロックする。In this closing piece 4, the base 4a is fitted into the recess 7 of the bottom plate 1c, and the rising prevention piece 11 on the front of the rising portion is inserted into the opening 6 of the bottom box front wall 1a, and the operating tongue piece 1 is inserted. 0 is received in the notch 5 of the front wall 1a and is attached to the inner surface of the bottom box. In this state, when the lid 3 is closed, the locking protrusion 3a is pushed along the inner surface of the lower end of the front wall of the lid 3, and the rising portion 4c of the closing piece 4 is bent rearward, and then the locking projection 3a is locked. The locking protrusion 9 enters the groove portion 8 to lock the lid body 3 on the bottom box 1.
【００２２】 蓋体３を開ける場合には、操作用舌片１０を押すと、図３に示すように係止突 起３が係止用溝部８から離脱すると共に操作用舌片１０の上面が蓋体３の正面壁 下端を若干上方に持ち上げるので、操作用舌片１０への押圧を解いてもそのまま では蓋体３に再ロックがかかることはなく、容易に蓋体３を開操作できる（図４ 及び図５参照）。When the lid 3 is opened, when the operating tongue 10 is pushed, the locking protrusion 3 is disengaged from the locking groove 8 and the upper surface of the operating tongue 10 is moved as shown in FIG. Since the lower end of the front wall of the lid 3 is lifted slightly upward, the lid 3 will not be re-locked even if the pressure on the operating tongue 10 is released, and the lid 3 can be easily opened ( (See FIGS. 4 and 5).
【００２３】 操作用舌片１０が立ち上がり部４ｃの上端により近い位置に設けられることと なるが、操作用舌片１０への押圧が繰り返されても浮き上がり防止片１１が底函 １の正面壁開口６に挿入されているので、閉鎖片自体が浮き上がってしまうこと はない。The operating tongue 10 is provided at a position closer to the upper end of the rising portion 4c. However, even if the operating tongue 10 is repeatedly pressed, the floating preventing piece 11 is provided with the floating preventing piece 11 on the front wall opening of the bottom box 1. Since it is inserted in 6, the closing piece itself does not float up.
【００２４】 また、屈曲部４ｂが内方に円弧状に湾曲しているので、立上がり部４ｃが無理 なく撓みかつ復帰し、疲労しにくい。Further, since the bent portion 4b is curved inward in a circular arc shape, the rising portion 4c flexes and returns without difficulty, and fatigue is less likely to occur.
【００２５】 図６は本考案の他の実施例に係る口止め部を適用した筆入れの正面壁要部の正 面図である。この実施例では、操作用舌片１１０を受け入れる切欠き部１０５を 蓋体１０３の正面壁下端に形成してあり、操作用舌片１１０の上面がこの切欠き 部１０５の上端にほぼ接触し、開操作時に操作用舌片１１０が切欠き部上端を介 して蓋体１０３を上方に押し上げる。なお、図中符号１０１は底函、１０６は浮 き上がり防止片１１１が差し込まれる開口である。FIG. 6 is a front view of an essential part of a front wall of a pencil case to which a mouth stopper according to another embodiment of the present invention is applied. In this embodiment, a notch 105 for receiving the operating tongue 110 is formed at the lower end of the front wall of the lid 103, and the upper surface of the operating tongue 110 substantially contacts the upper end of the notch 105, During the opening operation, the operating tongue 110 pushes the lid 103 upward through the upper end of the notch. In the figure, reference numeral 101 is a bottom box, and 106 is an opening into which the floating prevention piece 111 is inserted.
【００２６】 この実施例によれば、底函１０１の深さを一定にした場合、閉鎖片の立上がり 部がより長く設定され、下部を支点位置とする立上がり部の撓み変位をより楽に 行うことができる。According to this embodiment, when the depth of the bottom box 101 is constant, the rising portion of the closing piece is set longer, and the bending displacement of the rising portion with the lower portion as the fulcrum position can be performed more easily. it can.
【００２７】 上記した実施例では、本考案をプラスチック製の筆入れに適用した場合につい て説明したが、本考案はこれに限定されるものではなく、底函と蓋体とが開閉自 在に取り付けられた各種ケースの口止め部にそのまま適用できる。この場合、蓋 体は必ずしも函状を成すものである必要はなく、底函の正面壁と呼応する下がり 正面壁あるいは部分的な正面壁を有し、前記閉鎖片を取り付けて機能し得る構造 であれば、その具体的な形状、構造のいかんを問うものではない。In the above-mentioned embodiment, the case where the present invention is applied to the plastic pencil case has been described, but the present invention is not limited to this, and the bottom box and the lid can be opened and closed automatically. It can be applied as it is to the mouth stopper of various attached cases. In this case, the lid does not necessarily have to have a box shape, and has a lower front wall or a partial front wall corresponding to the front wall of the bottom box, and has a structure capable of functioning by attaching the closing piece. If so, it does not matter what the specific shape or structure is.
【００２８】[0028]
以上述べたように本考案によれば、閉鎖片の操作用舌片を底函あるいは蓋体の 正面壁端部に設けた切欠き部で受け入れるようにしたので、閉鎖片の係止部によ り近い位置に操作用舌片を形成させることができ、撓み弾性による係止力を同じ とすると、従来に比べてより小さな力で係止離脱操作、すなわちロック解除を行 うことができる。 As described above, according to the present invention, the operating tongue of the closing piece is received by the notch provided at the end of the front wall of the bottom box or the lid. The operating tongue can be formed at a position closer to the position, and if the locking force due to the flexural elasticity is the same, the locking / releasing operation, that is, the unlocking can be performed with a force smaller than the conventional one.
【００２９】 また、操作用舌片の上面が蓋体の正面壁下端などにほぼ接触する位置関係にあ る場合には、操作用舌片の押圧操作により係止離脱と同時に蓋体が押し上げられ て、開蓋操作を楽に行うことができる。Further, when the upper surface of the operating tongue is in a position to substantially contact the lower end of the front wall of the lid body, the lid body is pushed up at the same time when the operating tongue piece is pressed and released. Thus, the lid opening operation can be performed easily.
【００３０】 また、閉鎖片に浮き上がり防止片を設け、これを底函正面壁の開口に差し込め ば、閉鎖片が底函の所定位置から上方に位置ずれしたりすることがなくなる。Further, by providing the closing piece with a lifting prevention piece and inserting the piece into the opening of the front wall of the bottom box, the closing piece will not be displaced upward from the predetermined position of the bottom box.
