Description

【０００１】
【発明の属する技術分野】
本発明は、容器本体の収納部が中蓋で閉止され、更に、該中蓋を包囲するように外蓋が設けられて、該外蓋が容器本体の外周に螺合される気密容器に関する。
【０００２】
【従来の技術】
この種の気密容器としては、例えば実用新案登録第２５２３７８５号に開示される化粧用コンパクトが従来存在する。この化粧用コンパクトは化粧料の収納部を設けた容器本体と、該収納部の上側を覆う中蓋と、該中蓋を更に覆う外蓋とを備え、該外蓋を容器本体に螺合してねじ込むことにより、外蓋で中蓋を押圧して該中蓋による上記収納部の密閉性を高めるようになっている。また、上記中蓋はヒンジを介して容器本体に開閉自在に蝶着されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記化粧料コンパクトでは中蓋を容器本体に蝶着するヒンジは、該容器本体の周縁部上端を切欠いて、この切欠部の両側間に跨って蝶番ピンを設ける一方、中蓋の周縁部から外方に保持部を突設し、該保持部を蝶番ピンに嵌合支持することにより構成されるようになっており、中蓋は蝶番ピンを中心として回動される。このとき、保持部は蝶番ピンによって位置決めされており、外蓋のねじ込み力が作用して中蓋が容器本体の収納部に圧接される際にも、該中蓋は該蝶番ピンを中心として、中蓋のヒンジの配置側とは反対側のみが押し下げられる。このため、中蓋が収納部を閉止する周縁部にスカート条弁を設けたといえども、その圧接状態に偏りが発生して密閉性が低下されてしまうという課題があった。
【０００４】
そこで、本発明はかかる従来の課題に鑑みてなされたもので、外蓋のねじ込み力が作用した際に、中蓋がその全周において均等に沈み込むようにして、該中蓋による密閉性を高めるようにした気密容器を提供することを目的とする。
【０００５】
【課題を解決するための手段】
かかる目的を達成するために本発明は、
容器本体と、該容器本体に設けられた収納部の開口部を覆う中蓋と、該中蓋を包囲して容器本体の外周に螺合される外蓋とを備え、外蓋のねじ込み力を中蓋にその密閉方向へ付加して該中蓋により収納部を気密に保持するようにした気密容器において、上記中蓋の外周縁部に、該中蓋を上記容器本体に対して横向き水平方向へ平行に回動するために、該中蓋から垂下して回動支軸を設け、該回動支軸を容器本体に水平方向回りに回転自在に、かつその軸方向へ移動可能に嵌合したことを特徴とする。
【０００６】
この構成によれば、中蓋は水平方向回りに回転自在な回動支軸を中心として容器本体に対して横向き水平方向へ平行に回動されるようになっており、外蓋を取り外した状態で中蓋を回動することによって収納部を開放し、また閉止が行われる。そして、容器本体を密閉するには、中蓋で収納部を閉止した後、該中蓋を覆うようにして外蓋を被せ、そして、該外蓋を容器本体に螺合させて、これをねじ込むことにより行われ、このときの外蓋のねじ込み力が中蓋に付加される。このとき、容器本体に対して回動支軸がその軸方向に移動するので、上記ねじ込み力が付加された際に該中蓋を全体的に押し下げることができ、ひいては、中蓋による密閉性が向上される。
【０００７】
【発明の実施の形態】
以下、本発明の実施形態を添付図面を参照して詳細に説明する。図１から図４は本発明の気密容器の一実施形態を示し、図１は要部断面して示す分解斜視図、図２は密閉状態の縦断面図、図３は開放状態の縦断面図、図４は回動支軸の嵌合部分の動作説明図である。
【０００８】
本実施形態の気密容器１０は、外蓋１３を閉止した際に中蓋１２による容器本体１１の密閉性を高めるようにしたもので、容器本体１１と、該容器本体１１に設けられた収納部１１ａの開口部を覆う中蓋１２と、該中蓋１２を包囲して容器本体１１の外周に螺合される外蓋１３とを備え、外蓋１３のねじ込み力を中蓋１２に付加して該中蓋１２を密閉方向に押圧するようになっており、その基本とするところは上記中蓋１２の外周縁部に、該中蓋１２に対して垂直に垂下される回動支軸１６を設け、該回動支軸１６を容器本体１１に回転自在に嵌合するとともに、この嵌合部分で回動支軸１６の軸方向移動を許容し、この軸方向の移動機能により中蓋１２を全体的に押し下げて、収納部１１ａの開口部の全周に亘って均等に当接させることにある。
【０００９】
即ち、本実施形態の気密容器１０は、図１，図２に示すように携帯用の化粧料容器として構成した場合に例をとって示し、中央部に収納部１１ａが設けられた容器本体１１と、該収納部１１ａを開閉する中蓋１２と、該中蓋１２を包囲して容器本体１１の外周に螺合される外蓋１３とを備えた、いわゆるジャータイプの容器として構成される。
【００１０】
上記容器本体１１は円形状に形成され、その周縁部は収納部１１ａの内周を構成する内壁１１ｂが設けられるとともに、その内壁１１ｂの上端部から折り返して外壁１１ｃが垂下され、これら内壁１１ｂと外壁１１ｃとによって二重壁構造となっている。このとき、内壁１１ｂの上端は外壁１１ｃの上端より一段高く形成され、この高くなった内壁１１ｂ上端に中蓋１２が当接して、図外の化粧料が充填される収納部１１ａ内が密閉される。また、外壁１１ｃの上端部外周には上記外蓋１３を螺合するための雄ねじ部１４が形成されるとともに、該雄ねじ部１４の形成部分の下方部分は外方に膨出される拡径部１１ｄとなっている。
【００１１】
上記中蓋１２は、外蓋１３の内側に嵌合される円形状に形成され、その周縁部上面には断面台形状に隆起する環状座１２ａが形成されるとともに、底面には容器本体１１の上記内壁１１ｂより若干大径の円形凹部１２ｂが形成され、この円形凹部１２ｂ内にパッキン１５が嵌め込まれて固定される。また、中蓋１２の周縁部下面には、上記内壁１１ｂと上記外壁１１ｃとの間に対応した位置に、回動支軸１６が中蓋１２に対して垂直に垂設される。
【００１２】
一方、容器本体１１の内壁１１ｂと外壁１１ｃとの折曲げ部分に、該容器本体１１の下面に対して垂直となり、かつ上記回動支軸１６を回転自在かつ軸方向移動自在に嵌合する嵌合穴１７が形成され、この嵌合穴１７に該回動支軸１６が挿入されることにより、中蓋１２は該回動支軸１６を中心として回動自在に支持される。このとき、上記嵌合穴１７の下半部には若干大径となる拡径部１７ａが形成される一方、上記回動支軸１６の先端部には先細りのテーパ部分を備えた大径の円錐部１６ａが形成され、該円錐部１６ａは割り溝１６ｂによって縮径が可能となっている。
【００１３】
従って、回動支軸１６を嵌合穴１７に上方から差し込むことにより、上記円錐部１６ａは該嵌合穴１７内で縮径しつつ挿入され、そして、円錐部１６ａ全体が嵌合穴１７の拡径部１７ａに位置すると、該円錐部１６ａは弾発力により拡径して段差部１７ｂに係合され、回動支軸１６の抜止めが行われる。ところで、上記円錐部１６ａが上記拡径部１７ａ内に位置する状態では、中蓋１２のパッキン１５は内壁１１ｂの上端に当接された状態となる。
【００１４】
そして、このようにパッキン１５が内壁１１ｂの上端に当接した状態で、上記回動支軸１６には嵌合穴１７の上端から更に突出される余裕部分１６ｃが設けられ、この余裕部分１６ｃによって回動支軸１６の更なる押し込み方向の移動が許容されるようになっている。
【００１５】
上記外蓋１３は、円形状の天板１３ａの周縁部から面取り状の傾斜部分１３ｂを介して周壁１３ｃが垂下する断面逆Ｕ字状に形成され、該周壁１３ｃの内周には上記容器本体１１の外壁１１ｃに形成された雄ねじ部１４に螺合する雌ねじ部１８が形成される。また、上記傾斜部分１３ｂの内側には凸部１３ｄが周方向に等間隔をもって４箇所形成され、この凸部１３ｄは、外蓋１３を容器本体１１に螺合して、ある程度ねじ込み方向に移動した際に、上記中蓋１２の環状座１２ａ上面に当接されるようになっている。なお、該凸部１３ｄは周方向に適宜間隔を設けて間欠的に形成したが、これに限ることなく連続した環状に形成してもよい。
【００１６】
更に、外蓋１３を完全にねじ込んだ状態では、周壁１３ｃの下端は容器本体１１の拡径部１１ｄの上端近傍で止まるようになっており、これら外蓋１３と拡径部１１ｄとの外径を略等しくすることにより、容器全体が同一径となってその外観性が向上されるようになっている。
【００１７】
従って、かかる構成になる本実施形態の気密容器１０は、図２に示したように回動支軸１６を容器本体１１の嵌合穴１７に挿入しつつ中蓋１２を収納部１１ａの開口部を覆うようにして組付け、更にその上方から中蓋１２を包囲して外蓋１３を容器本体１１の雄ねじ部１４に螺着するようになっている。また、上記外蓋１３を螺着した状態で、該外蓋１３と中蓋１２との間に所定のスペースが設けられ、このスペースにパフ１９が収納される。
【００１８】
上記気密容器１０は、収納部１１ａに充填した化粧料を使用する際には、図３に示すようにまず外蓋１３を取り外した後に、中蓋１２を回動支軸１６を中心として回動することにより、収納部１１ａが開放されて化粧料が露出し、これを上記パフ１９ですくい取って使うことになる。そして、化粧が終了して上記気密容器１０を仕舞う場合は、中蓋１２を元に回動して収納部１１ａの開口部を覆った後に、その上から外蓋１３を被せて容器本体１１に螺合してねじ込むことにより、上記収納部１１ａが中蓋１２と外蓋１３とによって２重に閉止されるようになっている。
【００１９】
このように、中蓋１２および外蓋１３によって容器本体１１が閉止された状態では、上記収納部１１ａの開口部が中蓋１２のパッキン１５によって密閉される。即ち、外蓋１３の雌ねじ部１８を容器本体１１の雄ねじ部１４に螺合し、これがある程度ねじ込まれた時点で外蓋１３の凸部１３ｄが中蓋１２の環状座１２ａの上面に当接する。この状態から更に外蓋１３をねじ込んで行くと、このねじ込み力が環状座１２ａから中蓋１２の周縁部に入力され、これによってパッキン１５が上記収納部１１ａの開口部となる内壁１１ｂ上端に圧接される。
【００２０】
ところで、本実施形態では上記外蓋１３のねじ込み力を中蓋１２に作用させる際、該中蓋１２を回転自在に支持する回動支軸１６は軸方向にも移動自在となっているため、これの余裕部分１６ｃが嵌合穴１７内に押し込まれて該中蓋１２を全体的に押し下げることができる。つまり、図４（ａ）に示すように中蓋１２が単に閉止された状態では、パッキン１５が内壁１１ｂの上端に軽く当接されている。そして、外蓋１３のねじ込み力が中蓋１２に入力されると、図４（ｂ）に示すように回動支軸１６は嵌合穴１７内を下方に移動するため、該中蓋１２は全体的に押し下げられることになる。このため、パッキン１５は上記内壁１１ｂの上端との間で、その全周に亘って均等に圧接力を付加することができるようになり、その密閉追従性が向上して収納部１１ａの気密性が著しく高められる。
【００２１】
従って、このように収納部１１ａがパッキン１５によって密閉されることにより、該収納部１１ａ内に充填された化粧料の揮発などを防止して、その劣化を防ぐことができる。更に、上記パッキン１５の片当たりも無くなることから、該パッキン１５自体の耐久性をも向上することができる。
【００２２】
ところで、本実施形態ではパッキンを用いる例を示したが、当該パッキンを省略して中蓋の底面を直接内壁の上端に当接させるようにしてもよい。また、上記収納部１１ａ内に化粧料が直接充填される場合を開示したが、これに限ることなく図外の中皿に化粧料を充填して、その中皿を収納部１１ａに脱着自在に嵌め込んで用いることもできる。勿論、収納部１１ａへの収納物は化粧料に限らないことはいうまでもない。
【００２３】
【発明の効果】
以上説明したように本発明の気密容器にあっては、収納部の開口部を覆う中蓋の外周縁部から垂下した回動支軸を容器本体に水平方向回りに回転自在に嵌合して、収納部の開放および閉止を回動支軸を中心とする中蓋の横向き水平方向への回動により行うとともに、容器本体に対して回動支軸をその軸方向に移動可能としたので、外蓋のねじ込み力が付加された際に該中蓋を全体的に押し下げることができ、ひいては、中蓋と収納部の開口部との密閉性を向上して収納部の気密性を著しく向上することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an airtight container in which a storage portion of a container body is closed by an inner lid, an outer lid is provided so as to surround the inner lid, and the outer lid is screwed onto an outer periphery of the container body.
[0002]
[Prior art]
As this type of hermetic container, there is a conventional cosmetic compact disclosed in, for example, Utility Model Registration No. 2523785. The cosmetic compact includes a container body provided with a cosmetic storage section, an inner lid that covers the upper side of the storage section, and an outer lid that further covers the inner lid, and the outer lid is screwed onto the container body. By screwing in, the inner lid is pressed with the outer lid to enhance the sealing of the storage portion by the inner lid. The inner lid is hinged to the container main body through a hinge so as to be freely opened and closed.
[0003]
[Problems to be solved by the invention]
However, in the cosmetic compact, the hinge that hinges the inner lid to the container body has a notch at the upper end of the peripheral portion of the container body, and a hinge pin is provided across both sides of the notch portion, while the peripheral portion of the inner lid A holding part projects from the outside, and the holding part is fitted to and supported by a hinge pin. The inner lid is rotated around the hinge pin. At this time, the holding portion is positioned by the hinge pin, and even when the inner lid is pressed against the storage portion of the container body due to the screwing force of the outer lid, the inner lid is centered on the hinge pin, Only the side opposite to the arrangement side of the hinge of the inner lid is pushed down. For this reason, even if the skirt valve is provided at the peripheral edge where the inner lid closes the storage portion, there is a problem that the pressure contact state is biased and the sealing performance is deteriorated.
[0004]
Therefore, the present invention has been made in view of such conventional problems, and when the screwing force of the outer lid is applied, the inner lid sinks evenly around the entire circumference so as to improve the sealing performance by the inner lid. An object is to provide an airtight container.
[0005]
[Means for Solving the Problems]
In order to achieve this object, the present invention
A container main body, an inner lid that covers the opening of the storage portion provided in the container main body, and an outer lid that surrounds the inner lid and is screwed onto the outer periphery of the container main body. In an airtight container which is added to the inner lid in the sealing direction so as to hold the storage part in an airtight manner by the inner lid , the inner lid is disposed horizontally on the outer peripheral edge of the inner lid in the horizontal direction with respect to the container body. In order to rotate in parallel with the inner lid , a rotation support shaft is provided by hanging from the inner lid , and the rotation support shaft is fitted to the container body so as to be rotatable in the horizontal direction and movable in the axial direction. It is characterized by that.
[0006]
According to this configuration, the state the inner lid is adapted to be parallel to pivot the transverse horizontal direction with respect to the container body around a freely rotating shaft rotates horizontally around, removal of the outer lid By rotating the inner lid, the storage portion is opened and closed. In order to seal the container body, after closing the storage portion with the inner lid, the outer lid is covered so as to cover the inner lid, and the outer lid is screwed into the container body and screwed in. The screwing force of the outer lid at this time is applied to the inner lid. At this time, since the rotational support shaft moves in the axial direction with respect to the container body, the inner lid can be entirely pushed down when the screwing force is applied, and as a result, the sealing performance by the inner lid is reduced. Be improved.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 4 show an embodiment of an airtight container according to the present invention, FIG. 1 is an exploded perspective view showing a cross section of a main part, FIG. 2 is a longitudinal sectional view in a sealed state, and FIG. 3 is a longitudinal sectional view in an opened state. FIG. 4 is an explanatory view of the operation of the fitting portion of the pivot shaft.
[0008]
The airtight container 10 of the present embodiment is designed to enhance the hermeticity of the container main body 11 by the inner lid 12 when the outer lid 13 is closed. The container main body 11 and a storage portion provided in the container main body 11 An inner lid 12 that covers the opening of 11a, and an outer lid 13 that surrounds the inner lid 12 and is screwed onto the outer periphery of the container body 11, and the screwing force of the outer lid 13 is applied to the inner lid 12. The inner lid 12 is pressed in the sealing direction, and the basic point is that a rotating support shaft 16 that hangs perpendicularly to the inner lid 12 is provided on the outer peripheral edge of the inner lid 12. The rotating support shaft 16 is rotatably fitted to the container main body 11, and the axial movement of the rotating support shaft 16 is allowed at this fitting portion, and the inner lid 12 is moved by this axial movement function. By pushing down entirely and making it contact | abut uniformly over the perimeter of the opening part of the accommodating part 11a. That.
[0009]
That is, the airtight container 10 of the present embodiment is shown as an example when configured as a portable cosmetic container as shown in FIGS. 1 and 2, and the container body 11 provided with a storage portion 11 a at the center. And a so-called jar-type container comprising an inner lid 12 that opens and closes the storage portion 11a and an outer lid 13 that surrounds the inner lid 12 and is screwed onto the outer periphery of the container body 11.
[0010]
The container body 11 is formed in a circular shape, and the peripheral portion thereof is provided with an inner wall 11b that constitutes the inner periphery of the storage portion 11a, and the outer wall 11c is suspended from the upper end portion of the inner wall 11b, and the inner wall 11b A double wall structure is formed by the outer wall 11c. At this time, the upper end of the inner wall 11b is formed one step higher than the upper end of the outer wall 11c, the inner lid 12 abuts on the upper end of the inner wall 11b, and the inside of the storage portion 11a filled with cosmetics (not shown) is sealed. The Further, a male screw portion 14 for screwing the outer lid 13 is formed on the outer periphery of the upper end portion of the outer wall 11c, and a lower portion of the portion where the male screw portion 14 is formed is expanded in diameter 11d. It has become.
[0011]
The inner lid 12 is formed in a circular shape that fits inside the outer lid 13, and an annular seat 12 a that rises in a trapezoidal cross section is formed on the upper surface of the peripheral portion, and the bottom surface of the container body 11 is formed on the bottom surface. A circular recess 12b having a slightly larger diameter than the inner wall 11b is formed, and the packing 15 is fitted and fixed in the circular recess 12b. Further, on the lower surface of the peripheral edge portion of the inner lid 12, a rotation support shaft 16 is vertically suspended from the inner lid 12 at a position corresponding to between the inner wall 11 b and the outer wall 11 c.
[0012]
On the other hand, a fitting that fits the bent portion of the inner wall 11b and the outer wall 11c of the container main body 11 so as to be perpendicular to the lower surface of the container main body 11 and so that the rotating support shaft 16 is rotatable and axially movable. A joint hole 17 is formed, and the rotation support shaft 16 is inserted into the fitting hole 17, whereby the inner lid 12 is supported so as to be rotatable about the rotation support shaft 16. At this time, an enlarged diameter portion 17a having a slightly larger diameter is formed in the lower half portion of the fitting hole 17, while the distal end portion of the rotating support shaft 16 has a large diameter provided with a tapered portion. A conical portion 16a is formed, and the conical portion 16a can be reduced in diameter by a split groove 16b.
[0013]
Therefore, by inserting the rotation support shaft 16 into the fitting hole 17 from above, the conical portion 16a is inserted while being reduced in diameter in the fitting hole 17, and the entire conical portion 16a is inserted into the fitting hole 17. When positioned at the enlarged diameter portion 17a, the conical portion 16a is enlarged in diameter by the elastic force and engaged with the stepped portion 17b, and the rotation support shaft 16 is prevented from being removed. By the way, in the state where the conical portion 16a is located in the enlarged diameter portion 17a, the packing 15 of the inner lid 12 is in contact with the upper end of the inner wall 11b.
[0014]
In this state where the packing 15 is in contact with the upper end of the inner wall 11b, the rotary support shaft 16 is provided with a margin portion 16c further protruding from the upper end of the fitting hole 17, and the margin portion 16c Further movement of the pivot shaft 16 in the pushing direction is allowed.
[0015]
The outer lid 13 is formed in an inverted U-shaped cross section in which a peripheral wall 13c hangs down from a peripheral edge of a circular top plate 13a through a chamfered inclined portion 13b, and the container body is formed on the inner periphery of the peripheral wall 13c. A female screw portion 18 is formed which is screwed into the male screw portion 14 formed on the outer wall 11c of the eleventh. Further, four convex portions 13d are formed at equal intervals in the circumferential direction on the inner side of the inclined portion 13b, and the convex portions 13d are screwed into the container body 11 and moved to a certain degree in the screwing direction. In this case, the upper surface of the inner lid 12 is brought into contact with the upper surface of the annular seat 12a. In addition, although this convex part 13d provided the space | interval in the circumferential direction intermittently and formed intermittently, you may form not only in this but in the continuous cyclic | annular form.
[0016]
Further, when the outer lid 13 is completely screwed, the lower end of the peripheral wall 13c stops near the upper end of the enlarged diameter portion 11d of the container main body 11, and the outer diameter of the outer lid 13 and the enlarged diameter portion 11d. By making these substantially equal, the entire container has the same diameter, and its appearance is improved.
[0017]
Therefore, in the airtight container 10 of this embodiment having such a configuration, as shown in FIG. 2, the inner lid 12 is opened to the opening portion of the storage portion 11a while the rotation support shaft 16 is inserted into the fitting hole 17 of the container body 11. Further, the inner lid 12 is surrounded from above, and the outer lid 13 is screwed onto the male screw portion 14 of the container body 11. In addition, a predetermined space is provided between the outer lid 13 and the inner lid 12 in a state where the outer lid 13 is screwed, and the puff 19 is stored in this space.
[0018]
When using the cosmetic filled in the storage portion 11a, the airtight container 10 first rotates the inner lid 12 around the pivot shaft 16 after removing the outer lid 13 as shown in FIG. By doing so, the storage portion 11a is opened to expose the cosmetic, and the puff 19 is used for scooping it up. And when makeup is completed and the airtight container 10 is finished, after turning the inner lid 12 to cover the opening of the storage portion 11a, the container body 11 is covered with the outer lid 13 from above. By screwing and screwing, the storage portion 11 a is double-closed by the inner lid 12 and the outer lid 13.
[0019]
Thus, in a state where the container main body 11 is closed by the inner lid 12 and the outer lid 13, the opening of the storage portion 11 a is sealed by the packing 15 of the inner lid 12. That is, the female threaded portion 18 of the outer lid 13 is screwed into the male threaded portion 14 of the container body 11, and when this is screwed to some extent, the convex portion 13d of the outer lid 13 abuts on the upper surface of the annular seat 12a of the inner lid 12. When the outer lid 13 is further screwed from this state, this screwing force is input from the annular seat 12a to the peripheral edge portion of the inner lid 12, whereby the packing 15 is pressed against the upper end of the inner wall 11b serving as the opening of the storage portion 11a. Is done.
[0020]
By the way, in this embodiment, when the screwing force of the outer lid 13 is applied to the inner lid 12, the rotation support shaft 16 that rotatably supports the inner lid 12 is also movable in the axial direction. The margin portion 16c is pushed into the fitting hole 17 so that the inner lid 12 can be pushed down as a whole. That is, as shown in FIG. 4A, when the inner lid 12 is simply closed, the packing 15 is lightly abutted against the upper end of the inner wall 11b. When the screwing force of the outer lid 13 is input to the inner lid 12, the rotation support shaft 16 moves downward in the fitting hole 17 as shown in FIG. It will be pushed down overall. For this reason, the packing 15 can apply a pressure contact force uniformly over the entire periphery between the upper end of the inner wall 11b, and the hermetic followability is improved and the airtightness of the storage portion 11a is improved. Is significantly increased.
[0021]
Therefore, since the storage portion 11a is sealed with the packing 15 in this way, volatilization of the cosmetic filled in the storage portion 11a can be prevented and deterioration thereof can be prevented. Further, since the packing 15 does not come into contact with each other, the durability of the packing 15 itself can be improved.
[0022]
By the way, although the example which uses packing was shown in this embodiment, the said packing may be abbreviate | omitted and you may make it contact | abut the bottom face of an inner cover directly on the upper end of an inner wall. Moreover, although the case where cosmetics were directly filled in the said storage part 11a was disclosed, it is not restricted to this, cosmetics are filled into the inner dish outside a figure, and the inner dish can be freely attached or detached to the storage part 11a. It can also be used by fitting. Of course, it goes without saying that the items stored in the storage portion 11a are not limited to cosmetics.
[0023]
【The invention's effect】
As described above, in the hermetic container of the present invention, the rotation support shaft suspended from the outer peripheral edge of the inner lid covering the opening of the storage unit is fitted to the container body so as to be rotatable around the horizontal direction. Since the opening and closing of the storage portion is performed by turning the inner lid horizontally in the horizontal direction around the rotation support shaft, the rotation support shaft can be moved in the axial direction with respect to the container body. When the screwing force of the outer lid is applied, the inner lid can be pushed down as a whole. As a result, the airtightness of the storage portion is remarkably improved by improving the sealing property between the inner lid and the opening of the storage portion. be able to.
