Description

【0001】
【発明の属する技術分野】
本発明は、蓋の開閉構造と密閉性を改良した容器に関する。
【0002】
【従来の技術】
従来、ウエットペーパー等を収容する容器として、特開平9-39996 号公報に記載の如く、可撓性の天面部に開口部が形成された容器本体と、上記容器本体の天面部にヒンジにより回動可能に結合されて上記開口部を覆う蓋と、上記容器本体の天面部と上記蓋とにおける上記ヒンジ近傍に配設されて、弾性復元力により上記蓋を全開可能とする弾性体と、上記容器本体と上記蓋とに設けられ、該蓋の閉時に互いに係止して該蓋を閉蓋位置に保つ係止機構部とを有し、上記容器本体の天面部が押圧されることによる該容器本体の撓み変形により、上記係止機構部の係止作用が解除可能に構成されたものがある。この容器によれば、容器を床或いは机上等に置き、容器本体の天面部を片手で押圧するだけで、蓋を即座に全開させることができ、その片手で、天面部の開口部から容器本体の内容物を取り出すことができる。
【0003】
【発明が解決しようとする課題】
然しながら、従来技術には以下の問題点がある。
▲1▼容器の閉蓋時の密閉性は、容器本体の天面部における開口部の周囲に設けたシールリングに、蓋の内面に設けたシールリングを単に突き当てるものであり、十分でない。
【0004】
▲2▼蓋を容器本体に結合するヒンジは、蓋に設けたヒンジピンを容器本体に設けたヒンジ孔に嵌入するものであり、容器本体のヒンジ孔が該容器本体に貫通するようになっている。従って、この容器本体の貫通ヒンジ孔が容器の閉蓋時の密閉性を損なう。
【0005】
▲3▼上記▲1▼、▲2▼により、容器の閉蓋時の密閉性が十分でなく、容器の内容物、例えばウエットペーパーの含浸剤にエタノールの如くの揮発性物質を含んでいる場合には、内容物の成分が揮散し易い。
【0006】
本発明の課題は、容器において、閉蓋時の密閉性を向上することにある。
【0007】
【課題を解決するための手段】
請求項1に記載の本発明は、天面部に開口部が形成された容器本体と、上記容器本体の天面部にヒンジにより回動可能に結合されて上記開口部を覆う蓋と、上記容器本体の天面部と上記蓋とにおける上記ヒンジ近傍に配設されて、弾性復元力により上記蓋を全開可能とする弾性体と、上記容器本体と上記蓋とに設けられ、該蓋の閉時に互いに係止して該蓋を閉蓋位置に保つ係止機構部とを有してなる容器であって、上記容器本体の天面部における上記開口部の周囲にリング状の第1シール部を備えるとともに、上記蓋の内面における上記第1シール部に対応する部分に、該蓋の閉時に該第1シール部と密接するリング状の第2シール部を備え、第1シール部と第2シール部の少なくとも一方に設けたリング溝に弾性パッキンを設け、上記蓋を容器本体に結合するヒンジが、蓋に設けたヒンジピンを容器本体に設けたヒンジ孔に嵌入して構成され、容器本体に設けたヒンジ孔は該容器本体に凹状形成され該容器本体に非貫通とされてなるようにしたものである。
【0014】
【発明の実施の形態】
図1は容器を示す斜視図、図2は容器の開蓋状態を示す断面図、図3は容器の閉蓋状態を示す断面図、図4は容器本体と蓋の分離状態を示す模式図、図5は図4のVI-VI 線に沿う断面図、図6は変形例を示す模式図である。
【0015】
容器10は、使用目的に応じた液体(例えば水や薬液)を含浸したウエットペーパー等の内容物を収納する容器であり、図1〜図5に示す如く、容器本体11、蓋12とを有している。
【0016】
容器本体11は、ウエットペーパー等の内容物を収納可能とする箱体13と、この箱体13の上縁部に嵌着される中蓋14とを有する。そして、容器本体11は、中蓋14の天面部14Aに設けたシールリング15(第1シール部)内に開口部としての透口16を形成し、この透口16から、箱体13内の内容物を取出し可能としている。中蓋14は、天面部14A、側面部14Bの全体を可撓性を有するプラスチックにて構成している。
【0017】
蓋12は、容器本体11を構成している中蓋14の天面部14Aにヒンジ20を介して回動可能に結合され、容器本体11の透口16を覆う。
【0018】
そして、蓋12は、その内面にインナリング21、アウタリング22を備え、図3に示す如く、インナリング21の内周側に小リング21Aを設け、インナリング21と小リング21Aとの間のリング溝23に弾性パッキン24を装着している。蓋12に設けた弾性パッキン24は、中蓋14に設けてあるシールリング15に対応し、蓋12の閉蓋時に、シールリング15と密接して透口16を封止する。尚、この蓋12の閉蓋時に、蓋12のアウタリング22は中蓋14の天面部14Aに突き当たる。この透口16の密封により、容器本体11の内容物の成分の揮散を防止し、その湿潤状態を保つ。弾性パッキン24は、例えばシリコーンゴムからなるOリングを採用できる。
【0019】
また、蓋12を容器本体11の中蓋14に結合するヒンジ20は、蓋12に設けた一対のヒンジピン20Aを中蓋14の天面部14Aに設けた一対のヒンジ孔20Bに遊嵌して構成された間接接合ヒンジである。このとき、容器本体11の中蓋14に設けたヒンジ孔20Bは、図4、図5に示す如く、中蓋14に凹状形成され、中蓋14に非貫通とされる。
【0020】
容器本体11を構成している中蓋14の天面部14Aと、蓋12におけるヒンジ20の近傍には、ゴム状弾性体30が配設される。ゴム状弾性体30は、蓋12の閉蓋時に、中蓋14と蓋12との間で弾性変形し、この弾性復元力により蓋12を全開可能とする。
【0021】
ゴム状弾性体30は、一端部と他端部とを直角に交差させて一体化したL字状をなし(図2)、一端部を蓋12の裏面に設けた嵌合凹部31に嵌着し、他端部を蓋12の全開状態で中蓋14の天面部14Aに当接するように設定されている。
【0022】
尚、ゴム状弾性体30は、ゴム又はエラストマー等(例えばコンバウンドとして信越化学工業KE951Uと、加硫剤として同社製C−8とで合成されるメチルビニル系生ゴム)から構成される。
【0023】
容器本体11を構成している中蓋14におけるシールリング15のヒンジ20と反対側の外面には係止凹部41が設けられ、蓋12におけるインナリング21の内面には閉蓋時に上記係止凹部41に係止する係止凸部43を備えている。係止凹部41と係止凸部43は、係止機構部を形成し、蓋12の閉蓋時に互いに係止し、ゴム状弾性体30の弾性復元力に抗して蓋12を閉蓋位置に保つ。
【0024】
中蓋14側の係止凹部41と蓋12側の係止凸部43の係止作用は、容器本体11を構成している中蓋14の天面部14Aが押圧されることによるシールリング15の撓み変形により、解除される。即ち、中蓋14の天面部14Aが押圧力Fにより押圧されると、天面部14Aに連なるシールリング15が撓み変形を生じ、これによってシールリング15が箱内方側に反り返り、シールリング15の係止凹部41が蓋12の係止凸部43から外れるものとなる。
【0025】
尚、容器本体11を構成している中蓋14の天面部14Aで、蓋12が被着される部分の両側には、押圧指定部としてのエンボス50A、50Bが一体形成されている。エンボス50A、50Bは、天面部14Aの押圧変形をシールリング15の係止凹部41に最も伝え易い位置に設けられたものである。
【0026】
従って、容器10は、以下の如くに用いられる。
蓋12の閉蓋時には、中蓋14側の係止凹部41と蓋12側の係止凸部43との係止作用により、蓋12の閉蓋に伴って弾性変形されたゴム状弾性体30の弾性復元力に抗し、蓋12の閉蓋状態が維持される(図3)。
【0027】
蓋12の開蓋に際し、中蓋14のエンボス50A、50Bを押圧すると、前述の如くにより、中蓋14側の係止凹部41と蓋12側の係止凸部43との係止作用が解除される。これにより、ゴム状弾性体30の弾性復元力が蓋12の内面を押し、この蓋12を全開まで開蓋する(図2)。
【0028】
従って、本実施形態によれば、下記▲1▼〜▲3▼の作用がある。
▲1▼容器10の閉蓋時に、容器本体11の天面部14Aにおける透口16の周囲に備えたリング状の第1シール部(シールリング15)と、蓋12の内面に備えたリング状の第2シール部(インナーリング21)とを密接せしめるに際し、第1シール部と第2シール部の少なくとも一方に弾性パッキン24を設けた。従って、第1シール部と第2シール部の封着性を向上し、容器10の閉蓋時の密閉性を向上できる。
【0029】
▲2▼蓋12に設けたヒンジピン20Aを容器本体11に設けたヒンジ孔20Bに嵌入するに際し、容器本体11のヒンジ孔20Bが該容器本体11に非貫通とされた。従って、容器本体11のヒンジ孔20Bが容器10の閉蓋時の密閉性を損なうことがなく、その密閉性を向上できる。
【0030】
上記▲1▼、▲2▼により、容器10の閉蓋時の密閉性が十分となり、容器10の内容物、例えばウエットペーパーの含浸剤にエタノールの如くの揮発性物質を含んでいる場合にも、内容物の成分の揮散を抑制できる。
【0031】
▲3▼ゴム状弾性体30の弾性復元力が蓋12に作用した蓋12の閉蓋状態で、容器本体11の可撓性の天面部14Aが押圧されると、その天面部14Aに連なるシールリング15の撓み変形によって、係止機構部(中蓋14側の係止凹部41と蓋12側の係止凸部43)の係止作用が解除されることから、このとき、ゴム状弾性体30の弾性復元力により蓋12が全開し、天面部14Aの透口16が開く。このため、容器10を床或いは机上等に置き、容器本体11の天面部14Aを片手で押圧するだけで、蓋12を即座に全開させることができ、その片手で、天面部14Aの透口16から容器本体11の内容物を取り出すことができる。
【0032】
尚、上記実施形態では、第2シール部としてのインナリング21の側に弾性パッキン24を設ける場合について説明したが、本発明では、図6に示す如く、第1シール部としてのシールリング15の外側に小リング15Aを設け、シールリング15と小リング15Aとの間のリング溝25に弾性パッキン26を装着しても良い。また、本発明では、図6において、インナリング21の側の弾性パッキン24を撤去し、シールリング15の側の弾性パッキン26だけを備えるものとしても良い。
【0033】
以上、本発明の実施例を図面により詳述したが、本発明の具体的な構成はこの実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても本発明に含まれる。例えば、弾性パッキン24はOリングに限らず、平板状パッキンでも良く、またシリコーンゴムからなるものに限らず、ブチルゴム、熱可塑性エラストマーからなるものであっても良い。
【0034】
また、第1シール部と第2シール部の少なくとも一方に弾性パッキンを設けるものであれば良く、容器本体側の第1シール部に弾性パッキンを設け、或いは容器本体側の第1シール部と蓋側の第2シール部の両方に弾性パッキンを設けるものであっても良い。
【0035】
また、容器本体11を箱体13と中蓋14とで構成するとき、蓋12は箱体13にヒンジを介して結合するものでも良い。また、容器本体11を箱体13のみから構成するものであっても良い。
【0036】
また、ゴム状弾性体に代わる他の弾性体を用いることもできる。但し、ゴム状弾性体は、板ばね等の金属製でないので腐食せず、このため、容器本体内の内容物に錆が混入することがない。また、ゴム状弾性体の復元力は板ばね等のように過大でないため、蓋を適切な速度で緩やかに開くことができる。
【0037】
【発明の効果】
以上のように本発明によれば、容器において、閉蓋時の密閉性を向上することができる。

At this time, as shown in FIGS. 4 and 5, the hinge hole 20 </ b> B provided in the inner lid 14 of the container body 11 is formed in a concave shape in the inner lid 14 and is not penetrated through the inner lid 14.
[0020]
A rubber-like elastic body 30 is disposed in the vicinity of the top surface portion 14 </ b> A of the inner lid 14 constituting the container body 11 and the hinge 20 in the lid 12. The rubber-like elastic body 30 is elastically deformed between the inner lid 14 and the lid 12 when the lid 12 is closed, and the lid 12 can be fully opened by this elastic restoring force.
[0021]
The rubber-like elastic body 30 has an L shape in which one end portion and the other end portion are intersected at right angles and integrated (FIG. 2), and the one end portion is fitted into a fitting recess 31 provided on the back surface of the lid 12. The other end portion is set so as to abut on the top surface portion 14 </ b> A of the inner lid 14 in the fully opened state of the lid 12.
[0022]
The rubber-like elastic body 30 is composed of rubber, elastomer, or the like (for example, methyl vinyl raw rubber synthesized by Shin-Etsu Chemical KE951U as the bound and C-8 manufactured by the company as the vulcanizing agent).
[0023]
A locking recess 41 is provided on the outer surface of the inner lid 14 constituting the container body 11 opposite to the hinge 20 of the seal ring 15, and the locking recess 41 is formed on the inner surface of the inner ring 21 of the lid 12 when the lid is closed. A locking projection 43 that locks to 41 is provided.

[0024]
The locking action of the locking concave portion 41 on the inner lid 14 side and the locking convex portion 43 on the lid 12 side is such that the top surface portion 14 </ b> A of the inner lid 14 constituting the container body 11 is pressed. It is released by bending deformation. That is, when the top surface portion 14A of the inner lid 14 is pressed by the pressing force F, the seal ring 15 connected to the top surface portion 14A is bent and deformed, which causes the seal ring 15 to warp inward of the box, and the seal ring 15 The locking recess 41 is disengaged from the locking projection 43 of the lid 12.
[0025]
Note that embosses 50A and 50B as pressing designation portions are integrally formed on both sides of the top surface portion 14A of the inner lid 14 constituting the container main body 11 to which the lid 12 is attached. The embosses 50 </ b> A and 50 </ b> B are provided at positions where the pressing deformation of the top surface portion 14 </ b> A is most easily transmitted to the locking recess 41 of the seal ring 15.
[0026]
Accordingly, the container 10 is used as follows.
When the lid 12 is closed, the rubber-like elastic body 30 elastically deformed with the lid 12 being closed by the locking action of the locking concave portion 41 on the inner lid 14 side and the locking convex portion 43 on the lid 12 side. The lid 12 is kept closed against the elastic restoring force of FIG. 3 (FIG. 3).
[0027]
When the lid 12 is opened, when the embosses 50A and 50B of the inner lid 14 are pressed, the locking action between the locking recess 41 on the inner lid 14 side and the locking projection 43 on the lid 12 side is released as described above. Is done. Thereby, the elastic restoring force of the rubber-like elastic body 30 presses the inner surface of the lid 12 and opens the lid 12 until it is fully opened (FIG. 2).

Therefore, the sealing performance of the first seal portion and the second seal portion can be improved, and the sealing performance when the container 10 is closed can be improved.
[0029]
(2) When the hinge pin 20A provided on the lid 12 was fitted into the hinge hole 20B provided on the container body 11, the hinge hole 20B of the container body 11 was not penetrated into the container body 11. Therefore, the hinge hole 20B of the container main body 11 does not impair the sealing property when the container 10 is closed, and the sealing property can be improved.
[0030]
Due to the above (1) and (2), the container 10 is sufficiently sealed when the lid is closed, and the contents of the container 10, for example, a wet paper impregnating agent, also contains a volatile substance such as ethanol. , Volatilization of contents can be suppressed.
[0031]
(3) When the flexible top surface portion 14A of the container body 11 is pressed in the closed state of the lid 12 where the elastic restoring force of the rubber-like elastic body 30 acts on the lid 12, a seal connected to the top surface portion 14A. Since the locking action of the locking mechanism portion (the locking concave portion 41 on the inner lid 14 side and the locking convex portion 43 on the lid 12 side) is released by the bending deformation of the ring 15, at this time, the rubber-like elastic body The lid 12 is fully opened by the elastic restoring force of 30, and the through hole 16 of the top surface portion 14A is opened. Therefore, the lid 12 can be fully opened immediately by placing the container 10 on the floor or a desk and pressing the top surface portion 14A of the container body 11 with one hand, and the through-hole 16 of the top surface portion 14A can be opened with one hand. The contents of the container body 11 can be taken out of the container.

[0033]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. It is included in the present invention. For example, the elastic packing 24 is not limited to an O-ring but may be a flat packing, and is not limited to a silicone rubber, but may be a butyl rubber or a thermoplastic elastomer.
[0034]
Further, it is sufficient that at least one of the first seal portion and the second seal portion is provided with an elastic packing, and the first seal portion on the container body side is provided with the elastic packing, or the first seal portion and the lid on the container body side. An elastic packing may be provided on both of the second seal portions on the side.
[0035]
Further, when the container body 11 is constituted by the box body 13 and the inner lid 14, the lid 12 may be coupled to the box body 13 via a hinge. Further, the container main body 11 may be constituted only by the box 13.
[0036]
Further, other elastic bodies can be used in place of the rubber-like elastic bodies. However, since the rubber-like elastic body is not made of metal such as a leaf spring, it does not corrode, so that rust is not mixed into the contents in the container body. Further, since the restoring force of the rubber-like elastic body is not excessive like a leaf spring or the like, the lid can be opened gently at an appropriate speed.
[0037]
【The invention's effect】
As described above, according to the present invention, it is possible to improve the airtightness of the container when the lid is closed.
