Abstract

<P>PROBLEM TO BE SOLVED: To provide a multilayer container that securely protects contents from impact and also has large storage capacity. <P>SOLUTION: The multilayer container 1 is composed such that an inner container 3 is disposed in a container body 2 that is tightly closed by fitting a cap 4 over an opening 10. The inner container 3 includes: an inner opening 10 disposed inside the opening 10; and an inner container body 26 (23, 24, and 25) disposed further inside the container body 2 than the inner opening 10. The inner container body 26 is larger in diameter than the opening 10. The external surface of inner container body 26 has projections 27 and 28 in several areas projected to come in contact with the internal surface of the container body 2. Since the inner container body 26 bulge inside the container body 2, comparatively large capacity for storing the contents can be obtained. Further, this prevents the inner container 3 from sliding out of the container body 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【０００１】
本発明は，例えば錠剤などの内容物を衝撃から保護して収納する多層容器に関する。
【０００２】
【従来の技術】
一般に錠剤などを収納した容器では，開口部から樹脂シートなどの緩衝材を丸めて挿入して開口部をキャップで閉じ，錠剤等の内容物を緩衝材で押えることにより，内容物の移動を防止し，内容物の割れや欠けの防止を試みている。しかし，このような一般的な方法では，容器落下時の衝撃による割れや欠けなどの内容物の破損を完全には防止することができないので，容器を箱などに入れる等，緩衝効果のある更なる対策が必要となる。そこで，容器をいわゆる二重構造に構成したものとして，例えば特開２００１−３４１７７９号には，外容器内に弾性内容器を吊り下げた錠剤収納容器が開示されている。更に，特開２００１−１０６７２号などにも，化粧品などの内容物を衝撃から保護する多層容器が開示されている。

【発明が解決しようとする課題】
従来の多層容器は，内容器を外容器内にスムーズに挿入できるように，内容器の外径が外容器の開口部の径と同じかもしくは小さいのが普通であった。このため従来の多層容器は，内容器の外径を大きくできないため，内容物の収納容積が著しく小さくなるという問題があった。また，キャップを外して開口させた際や内容物を取り出す際などに，内容器が外容器内から抜け出す心配もあった。
【０００５】
また従来の多層容器は，いずれも内容器を外容器内に吊り下げた構成であり，内容器が外容器内において動く構造であった。このため従来の多層容器は，衝撃などを受けた場合や容器の姿勢を倒した場合に，内部で宙吊り状態になっている内容器が揺れ動くことにより外容器内面に衝突し，そのショックで内容器内に収納している内容物を破損する恐れがあった。
【０００６】
従って本発明の目的は，内容物を衝撃からより確実に保護でき，収納容積も大きい多層容器を提供することにある。
【０００７】
【課題を解決するための手段】
この目的を達成するために，開口部にキャップを取り付けることにより密閉される容器本体の内部に内容器を配置した多層容器であって，前記内容器は，前記開口部の内側に配置される内開口部と，この内開口部よりも前記容器本体の内部に配置される内容器本体部からなり，前記内容器本体部は，前記開口部よりも大きい径を有しており，前記内容器本体部の外面には，前記容器本体の内面に接するように突出する突部が複数箇所に形成されていることを特徴とする，多層容器が提供される。
【０００８】
本発明の多層容器は，内容器本体部が容器本体の開口部よりも大きい径を有しており，内容器本体部が容器本体の内部において膨らんだ状態になっているので，内容物の収納容積を比較的大きく確保することができる。しかも，内容器本体部が容器本体の内部で膨らんでいるため，内容器が容器本体内から抜け出す心配もない。
【０００９】
また本発明の多層容器は，内容器本体部の外面に形成された突部が容器本体の内面に接しているため，突部によって内容器本体部は容器本体の内面から支えられた状態となっている。このため，容器本体の内部において内容器本体部が揺れ動くことが少なく，外部から受けた衝撃などを内容器内に収納している内容物にほとんど伝えることがない。また，突部によって内容器本体部と容器本体の内面との間に好適な隙間を保持できるようになる。
【００１０】
前記内容器本体部は，変形可能であることが好ましい。内容器本体部が変形可能であれば，内容器本体部を開口部に通すことができる大きさに収縮させて，容器本体内に内容器を挿入することができるので，多層容器の製作が容易となる。
【００１１】
前記内容器本体部の周面及び底面に，前記突部が形成されていることが好ましい。そうすれば，内容器本体部の周面及び底面と容器本体の内面との間に好適な隙間を保持でき，容器本体の内部において内容器本体部が安定し，内容物の破損が防止される。この場合，前記内容器本体部の底面に形成された突部は，前記内容器内に内容物を入れていない状態では，容器本体の底面に接せず，内容器内に内容物を入れた状態で，はじめて容器本体の底面に接するものであっても良い。なお，前記内容器本体部の周面には，前記突部が複数箇所に形成されていることが好ましい。また，前記内容器本体部の周面に，縦方向に伸びる複数の突部が形成されていても良い。
また，前記内容器本体部の周面に縦方向に伸びる凹部が形成されていても良く，前記内容器本体部の下部をテーパー面に形成しても良い。更に，前記容器本体の開口部の内面と前記内容器の内開口部の外面の間に空気通路を形成しても良い。
【００１２】
前記容器本体と内容器の材質は同じであることが好ましい。そうすれば，分別せずにそのまま廃棄できるといった利点がある。
【００１３】
【発明の実施の形態】
以下，本発明の好ましい実施の形態を，図面を参照にして説明する。
図１，２に示すように，この多層容器１は，外容器となる剛性の容器本体２の内部に内容器３を配置した構成を有する。この実施の形態では，内容器３の内部には，内容物としての錠剤ａが入れられている。
【００１４】
この実施の形態では，容器本体２はポリエチレンで構成される。容器本体２の上端は円筒形状をなす開口部１０となっており，この開口部１０にキャップ４を取り付けることにより，容器本体３の内部が密閉されている。開口部１０へのキャップ４の取り付けは，開口部１０の外周面に設けられた雄ねじ１１と，キャップ４の内周面に設けられた雌ねじ３１を利用して，脱着自在に行われる。
【００１５】
容器本体２において，開口部１０の下方には，末広がり形状の肩部１２を介して胴部１３が設けてある。この実施の形態では，容器本体２の胴部１３は略四角柱形状をなしている。また，容器本体２の下方（胴部１３の下方）は，底面１５によって塞がれている。
【００１６】
キャップ４において，天板３２の下方には，ホルダ３３が取り付けてある。このホルダ３３の底面には，適当箇所に穴３４が設けてある。そして，このホルダ３３の内部に脱臭剤や吸湿剤などを収納することにより，適宜必要に応じて内容物である錠剤ａの劣化を防ぐようにしている。
【００１７】
容器本体２と同様，内容器３の上端も円筒形状をなす内開口部２０となっており，この内開口部２０は容器本体２の開口部１０の内側に配置されるようになっている。図３に示すように，内開口部２０の上端部にはフランジ２１が取り付けてある。このフランジ２１の内側縁の下方には，容器本体２の開口部１０の上端内面に接する支持部２２が設けてあり，図１に示すように容器本体２の内部に内容器３を配置した際には，容器本体２の開口部１０上面にフランジ２１の下面が接するとともに，開口部１０の上部内面に支持部２２が接するようになっている。
【００１８】
また，容器本体２の開口部１０にキャップ４を取り付けた際には，キャップ４に取り付けられたホルダ３３が，内開口部２０内に挿入されるようになっている。
【００１９】
図３に示すように，内容器３において，内開口部２０の下方には，肩部２３，胴部２４及び底面２５からなる内容器本体部２６が形成されている。内開口部２０と胴部２４の間は末広がり形状の肩部２３によって接続されている。また，内容器３の下面（胴部２４の下面）は，底面２５によって塞がれている。
【００２０】
図１に示すように容器本体２の内部に内容器３を配置した際には，このように肩部２３，胴部２４及び底面２５からなる内容器本体部２６が，内開口部２０よりも容器本体２の内部に配置される。この実施の形態では，内容器３の胴部２４は略円柱形状をなしており，内容器本体部２６の直径（胴部２４の外径）は，容器本体２の開口部１０の直径（内径）よりも大きくなっている。
【００２１】
内容器３において，内容器本体部２６（胴部２４）の周面には，縦方向に伸びる複数のリブ状の突部２７が放射状に配置されて形成されている。また，内容器本体部２６の底面２５には，下向きに突出する突起２８が形成されている。
【００２２】
内容器本体部２６の周面に形成された複数の突部２７の先端は，容器本体２の胴部１３の内面に接触しており，内容器本体部２６の周面（胴部２４）は，容器本体２の胴部１３の内面から所定の隙間を空けた状態に維持されている。また同様に，内容器本体部２６の底面２５に形成された突起２８の下端は容器本体２の底面１５に接触しており，内容器本体部２６の底面２５は，容器本体２の底面１５から所定の隙間を空けて持ち上げられた状態に維持されている。これにより，内容器本体部２６の内部は，容器本体２の内面から隙間を維持した状態で保持されている。
【００２３】
この実施の形態では，内容器３も容器本体２と同様にポリエチレンで構成される。但し，前述の容器本体２が全体的に比較的肉厚に構成されて剛性を有するのに対して，内容器３は，少なくとも肩部２３，胴部２４及び底面２５からなる内容器本体部２６は，比較的肉薄に構成されており，内容器本体部２６は小さい力で変形可能である。
【００２４】
さて，この多層容器１を組み立てる場合，先ず，例えば内開口部２０を通じて内容器３の内部を吸引するなどし，変形可能に構成された内容器本体部２６を収縮させ，容器本体２の開口部１０に通すことができる大きさにする。そして，収縮させた内容器本体部２６を，開口部１０に通して容器本体２内に挿入する。
【００２５】
そして，このように内容器３を容器本体２の内部に挿入した後，例えば内開口部２０を通じて内容器３の内部に空気を吹き入れることにより，変形可能に構成された内容器本体部２６を，容器本体２の内部で膨らませ，多層容器１を容易に組み立てることができる。この場合，図１に示すように，内容器３の内開口部２０を容器本体２の開口部１０の内側に配置させ，容器本体２の開口部１０上面にフランジ２１の下面を接しさせるとともに，開口部１０の上部内面に支持部２２を接しさせるようにする。このように容器本体２の内部で内容器本体部２６を膨らませた際には，内容器本体部２６周面の突部２７の先端が容器本体２の胴部１３内面に接触して，内容器本体部２６の周面（胴部２４）は容器本体２の胴部１３内面から所定の隙間を空けた状態に維持され，内容器本体部２６底面２５の突起２８の下端が容器本体２の底面１５に接触して，内容器本体部２６の底面２５は容器本体２の底面１５から所定の隙間を空けて持ち上げられた状態に維持される。これにより，内容器本体部２６の内部は，容器本体２の内面から隙間を維持した状態で保持される。
【００２６】
こうして製作された多層容器１は，容器本体２の内部で膨らまされた内容器本体部２６が容器本体２の開口部１０よりも大きい径を有しているので，内容物である錠剤ａの収納容積を比較的大きく確保することができる。しかも，内容器本体部２６が容器本体２の内部で膨らんでいるため，内容器３が容器本体２内から抜け出す心配もない。また，内容器本体部２６の内部は，容器本体２の内面から隙間を維持した状態で保持されており，突部２７，２８で支持されることにより，容器本体２の内部において内容器本体部２６が不用意に動くことがなく，容器本体２の外部から受けた衝撃などを内容器３の内部に収納している錠剤ａにほとんど伝えることがない。
【００２７】
以上，本発明の好ましい実施の形態を例示したが，本発明は以上に説明した形態に限定されない。図４，５に示すように，内容器３の下部（胴部２４の下部）を，下に向って細くなる略円錐形状のテーパー面５０に構成しても良い。また，内容器本体部２６（胴部２４）の周面に形成された複数のリブ状の突部２７の間に，縦方向に伸びる凹部５１を形成することが好ましい。この場合，凹部５１は，各突部２７の間にそれぞれ設けても良いが，図４，５に示すように，複数の突部２７の数個置きに適当箇所に凹部５１を設けても良い。更に，凹部５１は一箇所のみに設けても良い。
【００２８】
このように内容器本体部２６（胴部２４）の周面に凹部５１を形成しておけば，多層容器１を組み立てる場合において，内開口部２０を通じて内容器３の内部を吸引した際に，内容器本体部２６（胴部２４）の周面が凹部５１に沿って折れ曲ることとなり，内容器本体部２６を細長い形状に収縮させることができるので，容器本体２の開口部１０に通しやすい。また，内容器３の下部（胴部２４の下部）が，下に向って細くなるテーパー面５０に構成されていれば，内容器本体部２６を容器本体２の開口部１０により容易に通しやすくなり，多層容器１の組み立てが更にしやすくなるといった利点がある。なお，内容器本体部２６を容器本体２の開口部１０に通す際に引っかからないように，内容器本体部２６の底面２５に形成される突起２８の幅（長さ）は，容器本体２の開口部１０の内径よりも小さいことが望ましい。
【００２９】
また，図３等においては，内容器３の内開口部２０の外周面にリング形状の支持部２２を形成する例を説明したが，図４に示すように，内容器３の内開口部２０の外周面に複数の突起５５を形成しても良い。このように内容器３の内開口部２０の外周面に突起５５を形成しておけば，容器本体２の内部に内容器３を配置した際に，図６，７に示すように，容器本体２の開口部１０の内周面に突起５５が当接することにより，各突起５５同士の隙間において，容器本体２の開口部１０の内周面と内容器３の内開口部２０の外周面の間に空気通路５６が形成され，開口部１０の内周面と内開口部２０の外周面が密着しなくなる。
【００３０】
このため，内容器３を容器本体２の内部に挿入した後，内開口部２０を通じて内容器３の内部に空気を吹き入れて，内容器本体部２６を容器本体２の内部で膨らませる際に，容器本体２の内部に残った空気（内容器３の外側の空気）が，これら空気通路５６を通じて外部に排気されやすくなる。これにより，多層容器１をより容易に組み立てることができるようになる。
【００３１】
なお，このような空気通路５６を容器本体２の開口部１０の内周面と内容器３の内開口部２０の外周面の間に形成させるために，内容器３の内開口部２０の外周面の代りに，容器本体２の開口部１０の内周面に同様の突起を形成しても良い。また，突起の代りに，容器本体２の開口部１０の内周面もしくは内容器３の内開口部２０の外周面に，空気が流通できる溝を形成することによって，容器本体２の内部に残った空気を外部に排気させるための空気通路を構成しても良い。
【００３２】
また，このように多層容器１を組み立てた場合，図８に示すように，内容器３の底面２５（内容器本体部２６の底面２５）に形成された突起２８は，内容器３内に内容物である錠剤ａをまだ入れていない状態では，容器本体２の底面１５に接せず，内容器３内に錠剤ａを入れた状態で，はじめて突起２８が容器本体２の底面１５に接するように構成しても良い。
【００３３】
また，図１では，容器本体２肩部１２の内側に内容器３の肩部２３が接している状態を示したが，多層容器１を組み立てた状態，あるいは，多層容器１を組み立てて内容器３内に錠剤ａを入れた状態で，容器本体２肩部１２の内側に内容器３の肩部２３が接せず，両者の間に適当な隙間が形成されるように構成しても良い。
【００３４】
また，容器本体２の胴部１３が四角柱形状のものについて説明したが，容器本体２の形状は円柱形状や，任意の多角形状などであっても良い。また，内容器本体部２６の周面（胴部２４）に形成される突部２７の形状や個数，内容器本体部２６の底面２５に形成される突起２８の形状や個数はいずれも任意であり，内容器本体部２６の内部を容器本体２の内面から隙間を維持した状態で保持可能なものであれば良い。但し，後述するように，突起２８の形状は，錠剤ａなどの内容物が保持されないような，取出しの障害とならない形状であることが好ましい。
【００３５】
また，図３に示したように，例えば内容器本体部２６の周面に複数の突部２７が形成されている場合は，全部の突部２７の先端が容器本体２の胴部１３の内面に接触していなくても良い。複数の突部２７の内，一部の突部２７の先端が容器本体２の胴部１３の内面に接触していることにより，内容器本体部２６の内部が容器本体２の内面から隙間を維持した状態で保持されれば足りる。
【００３６】
また，容器本体２の容積が一定であっても，突部２７，２８の高さを変えることによって，内容器本体部２６の内容積を調整できる。このため，同じ容器本体２を用いた場合でも，内容器本体部２６の内容積を変えることによって容積を調整することが可能である。
【００３７】
なお，内容器本体部２６の周面に形成された突部２７のように内容器本体部２６の胴部２４の壁面を膨出させた場合，突部２７内に内容物である錠剤ａが入り込む心配がある。そうすると，入り込んだ錠剤ａが引っかかって取れなくなる等の心配を生ずる。そのような問題を回避するために，突部２７を膨出させて形成する場合は，その幅を内容物である錠剤ａが入り込まない大きさにするか，あるいは，錠剤ａが引っかからないように十分な幅とすることが望ましい。
【００３８】
また，容器本体２と内容器３の材質は，実施の形態で説明したようなポリエチレンに限られず，その他，種々の材質で容器本体２と内容器３を構成することができる。容器本体２と内容器３の材質は，同じでなくても良い。例えば，内側に配置される内容器３として光を遮断できる濃い色に着色されたものを使用することにより，遮光性のある内容器３とすることもでき，外見は統一されていながら，様々な性能を持った多層容器１を提供できる。なお，容器本体２と内容器３の材質を同じにした場合は，分別せずにそのまま廃棄できるといった利点がある。
【００３９】
また，内容器３を容器本体２の内部に挿入した状態で，容器本体２の開口部１０に内容器３の内開口部２０を熱溶着させても良い。そうすれば，容器本体２の内部において内容器本体部２６の外側に空気層が形成され，クッションの役割を果たすことができる。また，容器本体２の内部において内容器本体部２６の外側にシリカゲルなどを配置して防湿効果を高めることも可能である。
【００４０】
本発明の多層容器に収納される内容物は錠剤に限られない。例えば化粧品などを収納する容器についても本発明を適用できる。
【００４１】

本発明によれば，内容物を衝撃からより確実に保護でき，収納容積も大きい多層容器を提供することができる。

The present invention relates to a multi-layer container for storing contents such as tablets while protecting the contents from impact.
[0002]
[Prior art]
Generally, in containers that store tablets, etc., the cushioning material such as a resin sheet is inserted through the opening and closed, the opening is closed with a cap, and the contents such as tablets are pressed with the cushioning material to prevent the contents from moving. And attempts to prevent cracking or chipping of the contents. However, such a general method cannot completely prevent damage to the contents such as cracking or chipping due to an impact when the container is dropped. Measures are needed. Thus, as a container having a so-called double structure, for example, Japanese Patent Application Laid-Open No. 2001-341779 discloses a tablet container in which an elastic inner container is suspended in an outer container. Furthermore, Japanese Patent Application Laid-Open No. 2001-10672 discloses a multilayer container for protecting contents such as cosmetics from impact.

[Problems to be solved by the invention]
In the conventional multi-layer container, the outer diameter of the inner container is usually equal to or smaller than the diameter of the opening of the outer container so that the inner container can be smoothly inserted into the outer container. For this reason, in the conventional multilayer container, the outer diameter of the inner container cannot be increased, so that there is a problem that the storage volume of the contents is significantly reduced. Also, there was a concern that the inner container would fall out of the outer container when the cap was removed and opened or when the contents were taken out.
[0005]
In addition, the conventional multilayer containers each have a configuration in which the inner container is suspended in the outer container, and the inner container moves in the outer container. For this reason, the conventional multi-layered container collides with the inner surface of the outer container when it receives an impact or the posture of the container is tilted, causing the inner container suspended in the air to swing and colliding with the inner surface of the outer container. There was a risk of damage to the contents stored inside.
[0006]
Accordingly, an object of the present invention is to provide a multi-layer container capable of more reliably protecting the contents from impact and having a large storage volume.
[0007]
[Means for Solving the Problems]
In order to achieve this object, a multi-layer container having an inner container arranged inside a container body sealed by attaching a cap to the opening, wherein the inner container is disposed inside the opening. An opening, and an inner container main body disposed inside the container main body with respect to the inner opening, wherein the inner container main body has a larger diameter than the opening; A multi-layer container is provided, wherein a plurality of protrusions are formed on an outer surface of the portion so as to be in contact with an inner surface of the container body.
[0008]
In the multilayer container of the present invention, the inner container body has a diameter larger than the opening of the container main body, and the inner container main body is swelled inside the container main body. A relatively large volume can be secured. In addition, since the inner container body is swelled inside the container body, there is no fear that the inner container comes out of the container body.
[0009]
Further, in the multilayer container of the present invention, since the projection formed on the outer surface of the inner container main body is in contact with the inner surface of the container main body, the inner container main body is supported from the inner surface of the container main body by the projection. ing. For this reason, the inner container main body is less likely to sway and move inside the container main body, and almost no impact or the like received from the outside is transmitted to the contents stored in the inner container. Also, a suitable gap can be maintained between the inner container body and the inner surface of the container body by the projection.
[0010]
The inner container body is preferably deformable. If the inner container body is deformable, the inner container body can be shrunk to a size that allows it to pass through the opening, and the inner container can be inserted into the container body. It becomes.
[0011]
It is preferable that the protrusion is formed on a peripheral surface and a bottom surface of the inner container body. By doing so, a suitable gap can be maintained between the peripheral surface and the bottom surface of the inner container body and the inner surface of the container main body, the inner container main body is stabilized inside the container main body, and damage to the contents is prevented. . In this case, the protrusion formed on the bottom surface of the inner container body does not touch the bottom surface of the container body when the contents are not put in the inner container, and the contents are put in the inner container. In this state, it may be the one that contacts the bottom surface of the container body for the first time. Preferably, the protrusion is formed at a plurality of locations on the peripheral surface of the inner container body. Further, a plurality of protrusions extending in the vertical direction may be formed on the peripheral surface of the inner container body.
Further, a concave portion extending in the vertical direction may be formed on a peripheral surface of the inner container body, and a lower portion of the inner container body may be formed as a tapered surface. Further, an air passage may be formed between the inner surface of the opening of the container body and the outer surface of the inner opening of the inner container.
[0012]
It is preferable that the material of the container body and the inner container is the same. This has the advantage that it can be discarded without separation.
[0013]

The inner opening 20 and the body 24 are connected by a flared shoulder 23. The lower surface of the inner container 3 (the lower surface of the body portion 24) is closed by the bottom surface 25.
[0020]
When the inner container 3 is arranged inside the container main body 2 as shown in FIG. 1, the inner container main body 26 composed of the shoulder 23, the body 24, and the bottom surface 25 is larger than the inner opening 20. It is arranged inside the container body 2. In this embodiment, the body 24 of the inner container 3 has a substantially cylindrical shape, and the diameter of the inner body 26 (the outer diameter of the body 24) is equal to the diameter (inner diameter) of the opening 10 of the container body 2. ).
[0021]
In the inner container 3, a plurality of rib-shaped protrusions 27 extending in the vertical direction are radially arranged on the peripheral surface of the inner container main body portion 26 (body portion 24). Further, a projection 28 protruding downward is formed on the bottom surface 25 of the inner container body 26.
[0022]
The tips of the plurality of protrusions 27 formed on the peripheral surface of the inner container main body 26 are in contact with the inner surface of the trunk 13 of the container main body 2, and the peripheral surface (the trunk 24) of the inner container main body 26 is A predetermined gap is maintained from the inner surface of the body 13 of the container body 2. Similarly, the lower end of the projection 28 formed on the bottom surface 25 of the inner container body 26 is in contact with the bottom surface 15 of the container body 2, and the bottom surface 25 of the inner container body 26 is separated from the bottom surface 15 of the container body 2. It is maintained in a lifted state with a predetermined gap. As a result, the inside of the inner container body 26 is held with a gap maintained from the inner surface of the container body 2.
[0023]
In this embodiment, the inner container 3 is also made of polyethylene similarly to the container body 2. However, while the above-mentioned container body 2 is configured to be relatively thick as a whole and has rigidity, the inner container 3 has an inner container body portion 26 comprising at least a shoulder portion 23, a body portion 24 and a bottom surface 25. Is relatively thin, and the inner container body 26 can be deformed with a small force.
[0024]
When assembling the multilayer container 1, first, the inner container body 26, which is configured to be deformable, is contracted by, for example, sucking the inside of the inner container 3 through the inner opening 20, and the opening of the container main body 2. Make it large enough to pass through 10. Then, the contracted inner container main body 26 is inserted into the container main body 2 through the opening 10.
[0025]
After the inner container 3 is inserted into the container main body 2 as described above, the inner container main body 26, which is configured to be deformable, is blown into the inner container 3 through the inner opening 20, for example. The multi-layer container 1 can be easily assembled by being expanded inside the container body 2. In this case, as shown in FIG. 1, the inner opening 20 of the inner container 3 is arranged inside the opening 10 of the container body 2, and the lower surface of the flange 21 is brought into contact with the upper surface of the opening 10 of the container body 2. The support 22 is brought into contact with the upper inner surface of the opening 10. When the inner container body 26 is inflated inside the container body 2 in this manner, the tip of the protrusion 27 on the peripheral surface of the inner container body 26 comes into contact with the inner surface of the body 13 of the container body 2 and The peripheral surface (body 24) of the main body 26 is maintained at a predetermined gap from the inner surface of the body 13 of the container body 2, and the lower end of the projection 28 on the bottom surface 25 of the inner container body 26 is at the bottom of the container body 2. 15, the bottom surface 25 of the inner container body 26 is maintained in a state of being lifted from the bottom surface 15 of the container body 2 with a predetermined gap. As a result, the inside of the inner container body 26 is held with a gap maintained from the inner surface of the container body 2.
[0026]
In the multilayer container 1 manufactured in this manner, the inner container body portion 26 swelled inside the container body 2 has a diameter larger than the opening 10 of the container body 2, so that the tablet a as the content is stored. A relatively large volume can be secured. In addition, since the inner container body 26 is swelled inside the container body 2, there is no fear that the inner container 3 comes out of the container body 2. The interior of the inner container body 26 is held while maintaining a gap from the inner surface of the container main body 2, and is supported by the protrusions 27 and 28, so that the inner container main body 26 is maintained inside the container main body 2. 26 does not move carelessly, and almost no impact or the like received from the outside of the container body 2 is transmitted to the tablet a stored in the inner container 3.
[0027]
The preferred embodiments of the present invention have been described above, but the present invention is not limited to the embodiments described above. As shown in FIGS. 4 and 5, the lower portion of the inner container 3 (the lower portion of the body portion 24) may be configured as a substantially conical tapered surface 50 that becomes thinner downward. Further, it is preferable to form a vertically extending concave portion 51 between the plurality of rib-shaped protrusions 27 formed on the peripheral surface of the inner container body portion 26 (body portion 24). In this case, the concave portions 51 may be provided between the respective projecting portions 27, but as shown in FIGS. 4 and 5, the concave portions 51 may be provided at appropriate positions every several of the plurality of projecting portions 27. . Further, the concave portion 51 may be provided at only one place.
[0028]
If the concave portion 51 is formed on the peripheral surface of the inner container body portion 26 (the body portion 24) in this manner, when assembling the multilayer container 1, when the inside of the inner container 3 is sucked through the inner opening 20, The peripheral surface of the inner container main body 26 (the body 24) is bent along the concave portion 51, and the inner container main body 26 can be contracted into an elongated shape. Cheap. In addition, if the lower part of the inner container 3 (the lower part of the body part 24) is formed as a tapered surface 50 that is tapered downward, the inner container body 26 can be easily passed through the opening 10 of the container body 2. Therefore, there is an advantage that the assembly of the multilayer container 1 is further facilitated. The width (length) of the protrusion 28 formed on the bottom surface 25 of the inner container main body 26 is set so that the inner container main body 26 is not caught when the inner container main body 26 is passed through the opening 10 of the container main body 2. It is desirable that the diameter be smaller than the inner diameter of the opening 10.
[0029]
Further, in FIG. 3 and the like, an example in which the ring-shaped support portion 22 is formed on the outer peripheral surface of the inner opening 20 of the inner container 3 has been described, but as shown in FIG. A plurality of projections 55 may be formed on the outer peripheral surface of the. If the protrusion 55 is formed on the outer peripheral surface of the inner opening 20 of the inner container 3 as described above, when the inner container 3 is arranged inside the container main body 2, as shown in FIGS. The protrusion 55 abuts on the inner peripheral surface of the opening 10 of the container 2, so that the inner peripheral surface of the opening 10 of the container body 2 and the outer peripheral surface of the inner opening 20 of the inner container 3 in the gap between the projections 55. An air passage 56 is formed therebetween, so that the inner peripheral surface of the opening 10 and the outer peripheral surface of the inner opening 20 do not adhere to each other.
[0030]
For this reason, when the inner container 3 is inserted into the container body 2, air is blown into the inner container 3 through the inner opening 20 to expand the inner container body 26 inside the container body 2. The air remaining inside the container body 2 (air outside the inner container 3) is easily exhausted to the outside through these air passages 56. Thereby, the multilayer container 1 can be more easily assembled.
[0031]
In order to form such an air passage 56 between the inner peripheral surface of the opening 10 of the container body 2 and the outer peripheral surface of the inner opening 20 of the inner container 3, the outer periphery of the inner opening 20 of the inner container 3 is formed. Instead of the surface, a similar protrusion may be formed on the inner peripheral surface of the opening 10 of the container body 2. In addition, instead of the projection, a groove through which air can flow is formed in the inner peripheral surface of the opening 10 of the container body 2 or the outer peripheral surface of the inner opening 20 of the inner container 3, so that the groove remains inside the container main body 2. An air passage for exhausting the exhausted air to the outside may be formed.
[0032]
When the multilayer container 1 is assembled in this manner, as shown in FIG. 8, the projections 28 formed on the bottom surface 25 of the inner container 3 (the bottom surface 25 of the inner container main body 26) have the contents inside the inner container 3. In a state where the tablet a, which is an object, has not yet been inserted, the projection 28 contacts the bottom surface 15 of the container main body 2 for the first time when the tablet a is inserted in the inner container 3 without touching the bottom surface 15 of the container main body 2. May be configured.
[0033]
FIG. 1 shows a state in which the shoulder 23 of the inner container 3 is in contact with the inside of the shoulder 12 of the container body 2. However, the multilayer container 1 is assembled, or the inner container is assembled by assembling the multilayer container 1. In the state where the tablet a is put in the container 3, the shoulder 23 of the inner container 3 does not contact the inside of the shoulder 12 of the container body 2, and an appropriate gap may be formed between them. .
[0034]
Further, although the case where the body 13 of the container body 2 has a square pillar shape has been described, the shape of the container body 2 may be a cylindrical shape or an arbitrary polygonal shape. The shape and number of the protrusions 27 formed on the peripheral surface (body 24) of the inner container body 26 and the shape and number of the protrusions 28 formed on the bottom surface 25 of the inner container body 26 are arbitrary. In addition, any material can be used as long as it can hold the inside of the inner container main body 26 from the inner surface of the container main body 2 while maintaining a gap. However, as will be described later, it is preferable that the shape of the projection 28 is such that the contents such as the tablet a are not held and does not hinder the removal.
[0035]
As shown in FIG. 3, for example, when a plurality of protrusions 27 are formed on the peripheral surface of the inner container body 26, the tips of all the protrusions 27 are formed on the inner surface of the body 13 of the container body 2. It does not have to be in contact with. Since the tip of a part of the plurality of protrusions 27 is in contact with the inner surface of the body 13 of the container body 2, the inside of the inner container body 26 has a gap from the inner surface of the container body 2. It suffices if it is maintained in a maintained state.
[0036]
Further, even if the volume of the container main body 2 is constant, the internal volume of the inner container main body 26 can be adjusted by changing the height of the projections 27 and 28. Therefore, even when the same container main body 2 is used, the volume can be adjusted by changing the internal volume of the inner container main body 26.
[0037]
When the wall surface of the body 24 of the inner container main body 26 is bulged like the protrusion 27 formed on the peripheral surface of the inner container main body 26, the tablet a as the content is contained in the protrusion 27. I'm afraid to get in. In this case, there is a concern that the entered tablet a is caught and cannot be removed. In order to avoid such a problem, when the protrusion 27 is formed by bulging, the width is set to a size that does not allow the content of the tablet a, or the width is set so that the tablet a is not caught. It is desirable to have a sufficient width.
[0038]
Further, the materials of the container body 2 and the inner container 3 are not limited to polyethylene as described in the embodiment, and the container body 2 and the inner container 3 can be made of various other materials. The material of the container body 2 and the inner container 3 may not be the same. For example, by using an inner container 3 that is colored in a dark color that can block light as the inner container 3 disposed inside, the inner container 3 having a light-shielding property can be obtained. A multilayer container 1 having high performance can be provided. When the material of the container body 2 and the inner container 3 are made of the same material, there is an advantage that the container can be discarded without separation.
[0039]
Further, the inner opening 20 of the inner container 3 may be thermally welded to the opening 10 of the container main body 2 in a state where the inner container 3 is inserted inside the container main body 2. Then, an air layer is formed inside the container main body 2 outside the inner container main body portion 26, and can serve as a cushion. Further, it is also possible to arrange a silica gel or the like inside the container body 2 outside the inner container body portion 26 to enhance the moisture-proof effect.
[0040]
The contents stored in the multilayer container of the present invention are not limited to tablets. For example, the present invention can be applied to a container for storing cosmetics and the like.
[0041]
