Description

【０００１】
【発明の属する技術分野】
本発明は気密性容器に関し、詳しくは、ウェットティッシュ等を収納する気密性に優れた容器に関する。
【０００２】
【従来の技術】
ウェットティッシュ等を収納する気密性のある容器として、例えば、頂壁中央部に取り出し口を穿設した容器本体と、取り出し口に密嵌して閉塞するシール筒を蓋板裏面より垂設するとともに、後部を容器本体後部に回動可能に連結して容器本体上面を開閉可能に設けた蓋体とを備えてなる合成樹脂製のものが知られている。
【０００３】
これらは、容器本体と蓋体との軸着部にトーションバネを介在させて、蓋体前部の容器本体に対する係合を解除した際に自動的に開蓋する如く構成している。また、蓋体前部の係合解除手段として、図３に示す如く、容器本体50に嵌着した中蓋51の先端縁より折り返し係止した基板52の上面より支持突片53を一体に突設し、また、支持突片53の先端を押圧板54の裏面に一体に連結し、更に蓋体55の先端部には先端縁より内方へ切欠き部56を穿設して、この切欠き部56の下方に押圧板54を臨ませている。そして、押圧板54の外側端部を押し下げることにより、支持突片53を支点としてその内側端部が上方へ移行し、蓋体55の頂板57下面を押し上げて頂板57裏面より垂設したシール筒58と取り出し口59とに設けた係合突起60及び係止突起61の係合が外れ、トーションバネ（図示せず）の弾発力により蓋体55が開く如く構成している。
【０００４】
【発明が解決しようとする課題】
上記従来の容器は、押圧板54を押し下げるだけで簡単に開蓋し、また、蓋体55を押し下げるだけで簡単に閉蓋するため、使勝手が良く、使用上すこぶる便利であるが、トーションバネを使用しているため、その組み付け操作が面倒であり、また、近年の合成樹脂と金属との分別廃棄が要望されている点からも金属の使用は差し控えたいという問題点がある。
【０００５】
また、シール筒58の嵌合部分に係合突起60と係止突起61との係合手段を備えているので、その部分の気密性が若干劣る。
【０００６】
本発明では、上記した点に鑑み、金属製のトーションバネを使用しなくても、片手操作により簡単に開蓋することができるとともに、蓋体の一部を指先で上方から押すだけて閉蓋することができ、しかも構造も簡単で安価に製造でき、気密性にも優れた合成樹脂製の容器を提案するものである。
【０００７】
【課題を解決するための手段】
第１の手段として、頂壁２中央部に蓋板収納用の凹部ａを形成するとともに、凹部中央部に取り出し口３を形成し、且つ、凹部内前部を揺動板押し下げ用の押し下げ空間a1に形成してなる容器本体Ａと、凹部内に収納させた蓋板６の後部を容器本体上面後部に回動可能に連結するとともに、蓋板裏面中央部より垂設したシール筒７を取り出し口３を密閉して嵌合させ、且つ、容器本体上面に開閉可能に設けた蓋体Ｂとを備え、蓋板前部に穿設した指掛け用の窓孔９内に薄肉ヒンジ10を介して揺動板11を突設するとともに、凹部底壁上面より起立した支持突片12の先端を揺動板下面に当接させ、揺動板の外側端を押し下げた際に、薄肉ヒンジ部分が支持突片を支点として上方に押し上げられて窓孔への指掛けが可能となる如く構成した。
【０００８】
第２の手段として、前記第１の手段に於いて、上記取り出し口３が、上記凹部ａ中央部に上端を開口した筒状の取り出し口３である如く構成した。
【０００９】
第３の手段として、前記第１の手段に於いて、上記シール筒７と薄肉ヒンジ10との間の蓋板６裏面より下方へ垂設したフック13と、取り出し口３と支持突片12との間の凹部底壁上面より上方へ立設したフック14とを、閉蓋時に離脱可能に係合させた。
【００１０】
【発明の実施の形態】
以下、本発明の実施例の形態を図面を参照して説明する。
本発明の容器１は、容器本体Ａと蓋体Ｂとを備えている。
容器本体Ａは合成樹脂により形成されたもので、頂壁２中央部に蓋板嵌合用の凹部ａを形成するとともに、凹部ａ中央部に取り出し口３を形成し、また、凹部ａ内前部を揺動板押し下げ用の押し下げ空間a1に形成している。凹部ａは、蓋体Ｂの後述する蓋板を収納させるものであり、少なくとも蓋板が収納できる深さを備えており、蓋体の平面輪郭と略同様な平面形状とすると良い。また、前部においては、後述する揺動板の押し下げ空間を形成するものであり、少なくとも取り出し口３と後述シール筒との密嵌を解消する程度の指の押し込みが可能な深さを備えている。
【００１１】
図示例では、四角板状で周縁部に二条の突条で形成した嵌合凹溝を立設してなる底蓋A1と、該底蓋A1の嵌合凹溝に下端縁を密嵌して固定した四角筒状の周壁４上端縁より頂壁２を延設してなる胴部A2とから容器本体Ａを構成している。また、凹部ａは頂壁中央部を縦長四角形状に凹ませて形成しており、その中央部に上端を開口した円筒状の取り出し口３を設けている。取り出し口３は、図示例のものに限らず、単に凹部ａ中央部を開口することにより構成しても良い。
【００１２】
また、本実施例の凹部ａは、全体を同じ深さとしているが、例えば、揺動板押し下げ空間a1を形成する前部だけを深く、その他の部分を蓋板の肉厚程度に浅く形成することも可能である。
【００１３】
蓋体Ｂも合成樹脂により形成されたもので、凹部ａに収納させた蓋板６後部を容器本体Ａ上面後部に回動可能に連結するとともに、蓋板６裏面中央部より垂設したシール筒７を取り出し口３を密閉して嵌合させ、容器本体Ａ上面に開閉可能に設けている。
【００１４】
図示例では、凹部ａ周壁内周面上端部に外周縁を位置させて収納した矩形状の蓋板６を有し、蓋板６下面後端部より垂設した突部８両面を、凹部ａの周壁内面両側後端部に軸着，枢着等の適宜手段により回動可能に連結している。また、蓋板６裏面中央部より垂設した円筒状のシール筒７を取り出し口３の筒壁内面に密嵌させている。
【００１５】
本発明では、蓋板６前部に穿設した指掛け用の窓孔９内に薄肉ヒンジ10を介して揺動板11を突設させるとともに、凹部ａの底壁上面より起立した支持突片12の先端を揺動板11下面に当接させ、揺動板11の外側端を押し下げた際に、薄肉ヒンジ10部分が支持突片12を支点として上方に押し上げられて窓孔９への指掛けが可能となる如く構成している。従って、支持突片12は薄肉ヒンジ10の比較的近傍にその上面が当接する位置に立設すると良い。
【００１６】
また図示例では、シール筒７と薄肉ヒンジ10との間の蓋板６裏面より下方へフック13を垂設し、また、取り出し口３と支持突片12との間の凹部底壁上面より上方へフック14を立設し、閉蓋状態で各フックが離脱可能な程度の係合力により係合する如く構成している。各フックを設けることにより、より確実に蓋体Ｂの容器本体への係止を行う如く構成している。
【００１７】
上記の如く構成した容器を使用する場合に付いて説明すると、例えば、図１の実線の状態から指の先で揺動板11の外側端を押し下げると、各フック13，14の係合が外れるとともに、シール筒７の取り出し口３との密嵌が解除されて蓋板６前部が上方へ持ち上げられ、次いで指先を二点鎖線にある如く、窓孔９の前縁部を形成する蓋板６裏面に掛けて持ち上げれば蓋体Ｂは容易に開き、内容物を取り出すことが出来る。
【００１８】
使用後は蓋板６上面を押して蓋体Ｂ閉じれば、各フックが係合するとともに、シール筒７が取り出し口３の筒壁に密嵌し、元の状態に戻る。
【００１９】
【発明の効果】
以上説明した如く、本発明容器は、既述構成としたことにより、シール筒の取り出し口への嵌合により容器体内収納物を確実に密封することができるとともに、揺動板の押し下げによりシール筒の密嵌状態を解除し、次いで、窓孔へ掛けた指を引き上げるだけの簡単な操作で開蓋させることができるため、容器本体を固定しなくても片手での開蓋を容易に行える。
【００２０】
しかもトーションバネの如き金属を部材として使用しなくても蓋体の開閉が極めて容易に行えるため、廃棄の際に金属と合成樹脂とを分離する必要もない。
【００２１】
また、蓋板は凹部内に収納させているため、容器上面を略平坦面にすることが出来、積み重ねを容易に行える。
【００２２】
また、取り出し口が、凹部中央に上端を開口して垂設した筒状の取り出し口であるものにあっては、シール筒との嵌合面が広くとれるため、更に良好な気密性を得られるとともに、この様な形態にしても同様に片手での開蓋を容易に行えるという利点を兼ね備えている。
【００２３】
また、シール筒と薄肉ヒンジとの間の頂板裏面より下方へ垂設したフックと、取り出し口と支持突片との間の凹部底壁上面より上方へ立設したフックとを係合させてなるものにあっては、蓋体の係止を更に確実に行えるとともに、取り出し口部分にはフックが存在しないため良好な気密性を維持することができるという効果を合わせて発揮するものである。

BACKGROUND OF THE INVENTION
The present invention relates to an airtight container, and more particularly to an excellent airtight container for storing a wet tissue or the like.
[0002]
[Prior art]
As an airtight container for storing wet tissue, etc., for example, a container body having a takeout opening in the center of the top wall and a seal cylinder that is tightly fitted to the takeout opening and closed are suspended from the back of the lid plate A synthetic resin is known that includes a lid body that is pivotally connected to a rear portion of a container body and a top surface of the container body that can be opened and closed.
[0003]
These are configured such that a torsion spring is interposed in a shaft attachment portion between the container body and the lid so that the lid is automatically opened when the engagement of the front portion of the lid with the container body is released. Further, as shown in FIG. 3, as a means for releasing the engagement of the front part of the lid, the support protrusion 53 is integrally projected from the upper surface of the substrate 52 which is folded back from the leading edge of the inner lid 51 fitted to the container body 50. In addition, the tip of the support protrusion 53 is integrally connected to the back surface of the pressing plate 54, and a notch 56 is bored inward from the tip edge at the tip of the lid 55. The pressing plate 54 faces the lower part 56. Then, by pushing down the outer end portion of the pressing plate 54, the inner end portion thereof moves upward with the support protrusion 53 as a fulcrum, and the bottom surface of the top plate 57 of the lid 55 is pushed up so as to be suspended from the back surface of the top plate 57. The engagement projections 60 and the locking projections 61 provided at 58 and the take-out port 59 are disengaged, and the lid 55 is opened by the elastic force of a torsion spring (not shown).
[0004]
[Problems to be solved by the invention]
The above conventional container simply opens the lid simply by depressing the pressing plate 54, and simply closes the lid 55 by simply depressing the lid 55. Therefore, the assembly operation is troublesome, and there is a problem that the use of metal is refrained from the recent demand for separation and disposal of synthetic resin and metal.
[0005]
Further, since the engagement portion of the engagement projection 60 and the locking projection 61 is provided in the fitting portion of the seal cylinder 58, the airtightness of that portion is slightly inferior.
[0006]
In the present invention, in view of the above points, the lid can be easily opened by one-hand operation without using a metal torsion spring, and the lid can be closed simply by pushing a part of the lid from above with a fingertip. The present invention proposes a container made of a synthetic resin that can be manufactured, that has a simple structure, that can be manufactured at low cost, and that has excellent airtightness.
[0007]
[Means for Solving the Problems]

[0009]
As a third means, in the first means, a hook 13 suspended downward from the back surface of the cover plate 6 between the seal cylinder 7 and the thin hinge 10, a takeout port 3 and a support protrusion 12 The hook 14 erected upward from the upper surface of the bottom wall of the recess between the two was releasably engaged when the lid was closed .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The container 1 of the present invention includes a container body A and a lid B.
The container main body A is made of synthetic resin, and forms a recess a for fitting the cover plate in the central portion of the top wall 2 and also forms a takeout port 3 in the central portion of the concave portion a. Is formed in a push-down space a1 for pushing down the swing plate. The concave portion a is for accommodating a lid plate, which will be described later, of the lid body B, has at least a depth that the lid plate can be accommodated, and preferably has a planar shape substantially the same as the planar contour of the lid body. In addition, the front part forms a space for pushing down the swing plate, which will be described later, and has a depth at which the finger can be pushed in at least enough to eliminate the tight fit between the take-out port 3 and the seal cylinder, which will be described later. Yes.
[0011]
In the illustrated example, the bottom cover A1 is a quadrangular plate shape and has a fitting groove formed with two ridges on the peripheral edge, and the lower end edge is closely fitted in the fitting groove of the bottom cover A1. The container main body A is comprised from the trunk | drum A2 formed by extending the top wall 2 from the fixed square cylinder-shaped surrounding wall 4 upper end edge. The concave portion a is formed by denting the central portion of the top wall into a vertically long rectangular shape, and a cylindrical extraction port 3 having an upper end opened at the central portion. The extraction port 3 is not limited to the illustrated example, and may be configured by simply opening the central portion of the recess a.
[0012]
In addition, the concave portion a of the present embodiment has the same depth as a whole, but, for example, only the front portion for forming the rocking plate push-down space a1 is deep, and the other portion is formed as shallow as the thickness of the lid plate. It is also possible.
[0013]
The lid B is also made of a synthetic resin, and the rear part of the lid plate 6 accommodated in the recess a is connected to the rear upper part of the container body A so as to be rotatable, and the seal cylinder is suspended from the center part of the rear surface of the lid plate 6. 7 is sealed and fitted to the take-out port 3, and is provided on the upper surface of the container body A so as to be opened and closed.
[0014]
In the illustrated example, the recess 8 has a rectangular lid plate 6 that is housed with the outer peripheral edge positioned at the upper end portion of the inner peripheral surface of the peripheral wall. Are connected to the rear end portions on both sides of the inner surface of the peripheral wall so as to be rotatable by appropriate means such as pivoting or pivoting. Further, a cylindrical seal cylinder 7 suspended from the center of the back surface of the cover plate 6 is closely fitted to the inner surface of the cylinder wall of the take-out port 3.
[0015]
In the present invention, a swinging plate 11 is projected through a thin hinge 10 in a finger hole window 9 drilled in the front portion of the cover plate 6 and a support projecting piece 12 standing from the upper surface of the bottom wall of the recess a. When the outer end of the swinging plate 11 is brought into contact with the lower end of the swinging plate 11 and the outer end of the swinging plate 11 is pushed down, the thin hinge 10 part is pushed upward with the support projecting piece 12 as a fulcrum, so It is configured as possible. Therefore, it is preferable that the support projecting piece 12 is erected at a position where the upper surface abuts relatively near the thin hinge 10.
[0016]
In the illustrated example, a hook 13 is suspended downward from the back surface of the cover plate 6 between the seal cylinder 7 and the thin hinge 10, and above the upper surface of the bottom wall of the recess between the outlet 3 and the support protrusion 12. The hook 14 is erected so that the hooks can be engaged with each other by an engagement force that can be detached in the closed state. By providing each hook, the lid B is configured to be more securely locked to the container body.
[0017]
In the case of using the container configured as described above, for example, when the outer end of the swing plate 11 is pushed down with the tip of a finger from the state of the solid line in FIG. 1, the hooks 13 and 14 are disengaged. At the same time, the tight fitting of the seal cylinder 7 with the take-out port 3 is released, the front part of the cover plate 6 is lifted upward, and then the cover plate that forms the front edge of the window hole 9 so that the fingertip is in the two-dot chain line 6 If it is hung on the back surface and lifted, the lid B can be easily opened and the contents can be taken out.
[0018]
After use, when the upper surface of the cover plate 6 is pushed and the cover body B is closed, the hooks are engaged, and the seal tube 7 is tightly fitted to the tube wall of the take-out port 3 to return to the original state.
[0019]
【The invention's effect】
As described above, the container according to the present invention is configured as described above, so that the contents stored in the container can be reliably sealed by fitting the seal cylinder into the take-out port, and the seal cylinder can be pressed by pushing down the swing plate. Then, the lid can be opened by a simple operation of simply lifting the finger placed on the window hole and then opening the lid with one hand without fixing the container body.
[0020]
Moreover, since the lid can be opened and closed very easily without using a metal such as a torsion spring as a member, it is not necessary to separate the metal and the synthetic resin at the time of disposal.
[0021]
Further, since the lid plate is housed in the recess, the upper surface of the container can be made substantially flat and can be easily stacked.
[0022]
Further, in the case where the take-out port is a cylindrical take-out port that is vertically provided with the upper end opened at the center of the recess, the fitting surface with the seal tube can be widened, so that even better airtightness can be obtained. In addition, even in such a form, there is an advantage that it can be easily opened with one hand.
[0023]
In addition, a hook that hangs downward from the back surface of the top plate between the seal cylinder and the thin hinge is engaged with a hook that is erected upward from the upper surface of the bottom wall of the recess between the outlet and the support protrusion. According to the present invention, the lid body can be locked more reliably, and since there is no hook at the take-out port portion, the effect of maintaining good airtightness is also exhibited.
