Description

【0001】
【発明の属する技術分野】
本発明は密封容器に関する。
【0002】
【従来の技術】
従来より市販されている弁当などには、醤油やマヨネーズ、ドレッシングなどを小さい袋に充填したものが付いていることがある。そのような袋は、図に示すように、ポリエチレンやポリプロピレンなどの合成樹脂製のシート101を2枚重ね、周縁部102を熱溶着して密封している。そして熱溶着した一部に切れ目103を設けており、使用時に切れ目103から袋100の一部を切断して内容物を取り出す構造になっている。この製品では、切れ目103から切断し、袋100を指で押さえて内容物を取り出すが、袋100を押した状態で切れ目103を切断してしまうと内容物が思わぬ方向に飛び散る場合がある。そのためこのような袋を開封する場合は、周縁部102を摘むなど、できるだけ袋100を押さずに切れ目103を切断する必要がある。
【0003】
また、常温で気化する内容物、あるいは蒸気圧を有する内容物を充填した袋の場合は、袋100を押さない状態で開封しても、切れ目103から内容物が飛び出てくる。そのため、切れ目103を内容物を受ける容器などに向けた上で、慎重に開封したり、切れ目103を上に向けて少し開封し、一旦ガスだけを放出し、その後、大きく開封するなどの手順が必要である。
【0004】
他方、図に示すような、袋100の角部分などに先端が閉じた細い通路104を設け、その通路の途中を切断させるように切れ目103を設けたものもある。このものは想像線のように切断した後、内容物は通路104の方向に飛び出す。そのため容器などに受けやすい利点がある。しかし切断した直後に切り口から内容物が飛び出す点では前述の場合と同じであり、周囲を汚すおそれは充分には解消されていない。
【0005】
【発明が解決しようとする課題】
本発明は誤って指で押圧した状態で開封しても、さらに内容物が蒸気圧を有するものであっても、開封直後に噴出せず、そのため周囲に飛び散る危険性が少ない密封容器を提供することを技術課題としている。
【0006】
【課題を解決するための手段】
本発明の密封容器(請求項1)は、2枚のシートからなる袋状の容器本体と、その容器本体内に内装される排出部材とからなり、前記排出部材の先端部は外部に開口しており、
排出部材は、その先端部から離れた位置に、常時は容器本体の内部と連通せず、外力により開放されて連通する閉鎖部を有し、前記閉鎖部が、排出部材の基端部近辺に設けられた、折り曲げ及び捻りによって破断する弱め線、又は折り曲げ若しくは捻りによって破断する弱め線を有し、前記排出部材の基端部には、前記2枚のシートの間に挟まれた摘み片が設けられていることを特徴としている。
本発明の密封容器の第2の態様(請求項2)は、2枚のシートからなる袋状の容器本体と、その容器本体内に内装される排出部材と、その排出部材に連結されるプラグとからなり、前記排出部材は、容器本体の外部に開口した先端部と、容器本体に配置され、開口した基端部とを有し、前記プラグには、前記2枚のシートの間に挟まれた摘み片が設けられており、前記プラグは、基端部の開口部に液密状態に詰めて連結され、前記プラグを基端部から抜き取ると、前記排出部材内と容器本体内が連通することを特徴としている。
本発明の密封容器の第3の態様(請求項3)は、2枚のシートからなる袋状の容器本体と、その容器本体内に内装される排出部材と、その排出部材に連結されるプラグとからなり、前記排出部材は、容器本体の外部に開口した先端部と、容器本体の内部に配置され、開口した基端部とを有し、前記プラグには、前記2枚のシートの間に挟まれた摘み片が設けられており、前記プラグは、基端部の開口部に液密状態に詰めて連結され、前記排出部材の基端部が円筒状に構成されており、前記プラグが円筒状に構成されており、前記プラグは、前記基端部の開口部に対して回動自在に、かつ、液密状態で嵌合されており、前記プラグおよび基端部は、それぞれ特定の回転位置で排出部材内と容器本体内が連通する窓を備えていることを特徴としている。
【0007】
このような容器では、容器本体の内部が隔壁によって少なくとも2室に仕切られており、閉鎖部を開放するときに各室が排出部材と連通するように構成されていてもよい(請求項4)。さらに、容器本体の内部排出部材によって少なくとも2室に仕切られており、閉鎖部を開放するときに各室が排出部材と連通するように構成されていてもよい(請求項5)。
【0008】
【作用および発明の効果】
本発明の密封容器(請求項1、2および3)は、常時、排出部材は閉鎖部またはプラグにより閉じているので、容器内部と排出部材とは連通していない。そのため排出部材の内部が先端部の開口で外部と連通していても、容器本体の内部は密封されている。そして閉鎖部を外力で連通させる、またはプラグを基端部から抜き取り連通させる、またはプラグを基端部に対して回動し連通させると、内容物は、直接外部に噴出せず、まず排出部材内に入る。そして内容物は排出部材にある程度溜まった後、排出部材の開口から外部に出てくる。すなわちこの密封容器では排出部材がいわばバッファとして機能し、閉鎖部を開封してから排出部材の先端から内容物が吐出するまでは若干の経過時間があるので、いきなり排出口より飛び出したりすることはない。そのため、使用者は内容物の吐出に備えて開口を受け皿などに向けることができる。
【0009】
また排出部材が容器本体内に内装されており、排出部材の先端が容器本体の一端で外部に開口しているため、排出部材が容器本体の内部に内装されているので、全体の長さを短くすることができ、取り扱いに便利である。さらに片手で容器本体の端部の開口を吐出させるべき受け皿などに向けさせ、反対側の手で先端部から離れた位置の閉鎖部を開放させることができるので、操作性がよい。
【0010】
さらに請求項1の密封容器では、閉鎖部が、排出部材の基端部近辺に設けられた、折り曲げ及び捻りによって破断する弱め線、又は折り曲げ若しくは捻りによって破断する弱め線を有する部材からなるため、排出部材の基端部を容器本体の外側から折り曲げたり、捻ったりして容易に破断することができ、それにより閉鎖部を容易に連通させることができる。
【0011】
容器本体の内部が隔壁によって少なくとも2室に仕切られており、閉鎖部を開放するときに各室が排出部材と連通するように構成されている密封容器(請求項4)では、二種類の内容物を別々に収容しておくことができ、使用時に排出部材の内部で混合することができる。なお、一種類の内容物を各室に充填しておくこともできる。容器内部に排出部材が内装されている密封容器の場合は、容器本体の内部を仕切る隔壁として、排出部材を採用することもできる(請求項5)。このものは、別個に隔壁を準備する必要が無く、部品が少なくて済む。さらに容器本体は排出部材によって補強および保形されるので、重量のある内容物を収納した場合でも安定する。
【0012】
【発明の実施の形態】
つぎに図面を参照しながら本発明の密封容器の実施の形態を説明する。図1は本発明の密封容器の一実施形態を示す一部切り欠き斜視図、図2aおよび図2bは図1の密封容器の一部切り欠き平面図および縦断面図、図3a〜cはそれぞれ本発明に関わる閉鎖部の他の実施形態を示す一部切り欠き要部正面図、図4a〜cはそれぞれ本発明の密封容器の他の実施形態を示す横断面図、図5は本発明の密封容器のさらに他の実施形態を示す一部切り欠き斜視図である。
【0013】
図1に示す密封容器10は、重ね合わせて周縁部11を熱溶着した2枚のシートからなる袋状の容器本体12と、その容器本体内に内装された筒状の排出部材13とから構成されている。容器本体12の中央部の内部で、排出部材13を除く範囲の2枚のシートの間の空間Sは、内容物を充填する収納部である
【0014】
前記容器本体12を構成するシートは、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体、ポリエチレンテレフタレート、ナイロンなど、従来公知の密封容器に使用される熱溶着可能な合成樹脂製の可撓性のシートが用いられる。なお上記の熱溶着性を有する内層フィルムに、ガスバリア性を有するアルミニウム箔などの金属箔を積層したり、アルミニウムなどの金属やシリカ、炭素などを蒸着した外層フィルムを積層するなど、異なる種類の材質の2枚以上のフィルムを積層したラミネートシートを用いてもよい。さらに容器本体12を構成する2枚のシートは通常は同じ種類の材質のシートであるが、異なる種類のシートを用いてもよい。また、互いに熱溶着しない2枚のシートを用い、それらの間に両方に対して熱溶着可能なフィルムを介在させてもよく、さらに接着剤をコーティングして接着することもできる。
【0015】
前記排出部材13は、先端部13bが開放され、基端部13aが閉じている筒状の部材であり、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレートなどの合成樹脂で構成される。なお、金属やガラスなど、他の材料でもよい。排出部材13は内容物の内圧によって中空部が押しつぶされない程度の固さを有するものが好ましい。ただし可撓性を有するもの、柔軟なものであってもよい(図参照)。排出部材13の基端部13aには、平板状の摘み片14が一体に設けられている。摘み片14の根元部14aは、この実施形態では排出部材13の蓋になっている。排出部材13の外周で、基端部13aからいくらか先端側に寄った位置には、折り曲げあるいは捻りによって容易に破断させることができ、しかも破断される前は排出部材13の内部と外部を気密・液密状態を維持する環状の溝(弱め線)15が形成されている。弱め線15は請求項1の閉鎖部であり、容器本体12の収納部S内に配置されている。なお図1では排出部材13の断面形状は円形であるが、楕円状であってもよく、角筒状であってもよい。
【0016】
排出部材13の基端部13aの近辺および先端部13bは図2aおよび図2bに示すように、それぞれ2枚のシートの間に挟まれ、収納部Sと外部との気密性および液密性を維持するように熱溶着または接着されている。摘み片14は2枚のシートでまれている。熱溶着してもよく、排出部材13とシートとの密着性が強くなって操作がし易くなる。さらに摘み片14を捻ったときにシートと排出部材13の熱溶着が剥がれにくい。
【0017】
このように構成される密封容器10に内容物を充填するには、たとえば容器本体12の周縁部11の一辺、たとえば図2の下部側を熱溶着せずに開放しておき、その開放部から内容物を充填し、その後、熱溶着して密封する。内容物は通常はドレッシングや化粧水、シャンプー、リンスなどの液体、マヨネーズなどのクリーム状のものなど、従来、袋に充填していたものをいずれも採用しうる。
【0018】
内容物を充填し、密封した密封容器10は、図2bに示すように、収納部Sが外部から遮断されている。この密封容器10を開封するには、たとえば片方の手で容器本体12の上から排出部材13の先端部13bないし中央部を摘み、他方の手で摘み片14を摘んで捻る。そうすると図2の弱め線15の位置で排出部材13が破断され、基端部13a側と先端部13b側とに分離する。なお、容器本体12は可撓性を有するので、摘み片14を捻るときにそれほど邪魔にならない。そして弱め線15で完全に分離した後も、摘み片14と基端部13aは容器本体12に挟まれているので、抜け落ちることはなく、容器本体12に付着されている。しかし一旦分離した弱め線15の部位はシール作用が奏されないので、内容物は、矢印Pで示すように、排出部材13の破断によって生じた開口部16から排出部材13の内部に入る。
【0019】
しかし排出部材13の内部はそれまで空洞であったため、その空洞内に内容物が入っても直ちに先端部13bの開口から噴出することはない。そしていくらか時間が経過してから、開口から内容物が流れ出る。そのため使用者は摘み片14を捻るときはその作業に集中することができ、弱め線15で排出部材13を破断した後、内容物を開口からたとえば受け皿などに流し出すことに集中できる。このように破断した直後でも、内容物が一旦排出部材13内に入っていわばバッファ作用が奏されるので、内圧がある場合でも、破断とともに噴出するおそれがない。
【0020】
したがって内容物としては、水、アルコールなどの常温で蒸気圧が低い成分のほか、ブタン、ペンタン、ヘキサンなど、常温で蒸気圧を有するもの、あるいは混合することにより蒸気圧を発生する成分を含んでいてもよい。蒸気圧を有する成分を含む場合、該成分や、該成分と共に配合される成分、さらに容器本体を冷却してから充填するのが好ましい。そのような蒸気圧を有するものでも、開封後に噴出することがない。また、蒸気圧によって生ずる内圧を有効に利用し、内容物の圧力で噴出させるようにしてもよい。前記内容物の具体例としては、水、低級アルコール、多価アルコール、シリコーンオイル、炭化水素油、エステルオイルなどに、トリートメント剤、セット剤、艶消し剤、染毛剤、脱毛剤などの頭髪用、皮膚軟化剤、保湿剤、角質除去剤、殺菌剤、消毒剤、クレンジング剤、シェービング剤、制汗剤、消炎鎮痛剤、害虫忌避剤、化粧水、コロン、消臭剤、美白剤などの人体用などの有効成分を溶解もしくは分散させたもの、さらにこれらに前記蒸気圧を有する成分を配合したものがあげられる。また、吐出形態(ミスト、泡、クリーム、ゲル)に応じて、界面活性剤や増粘剤などを配合することができる。
【0021】
図1の密封容器10では、排出部材13の基端部13aの近辺に形成した環状溝15によって閉鎖部が形成されているが、折り曲げによって破断させる場合は、排出部材13の上面側あるいは下面側に線状の溝を形成してもよく、両方に形成してもよい。また、側面側に弱め線を形成してもよい。さらに図3aに示すように、排出部材13を基端部側21と先端部側22とをあらかじめ分離しておき、両者の端面21a、22a同士を当接させた上で、その隙間をアルミニウム箔などの容易に破断しうるシート23で密封するようにしてもよい。
【0022】
図3bに示す閉鎖部25は、排出部材13の基端部13aを開口させ、その開口部26にプラグ27を液密状態で詰めている。そしてプラグ27の端部に摘み28を一体に設けている。このものは摘み28を摘んでプラグ27を排出部材13の基端部13aから抜き取ると、開口部26によって排出部材13の内部と容器本体12の収納部Sとが連通する。
【0023】
図3cに示す閉鎖部30では、排出部材13の基端部13aを円筒状に構成し、その内部に円筒状のプラグ31を回動自在に、且つ、液密状態で嵌合させている。そして排出部材13の基端部13aおよびプラグ31には、それぞれ特定の回転位置で連通する窓32、33が形成されている。そして通常はプラグ31は、窓32、33同士が連通しない位置に係止させておき、使用時にプラグ31を回動させて窓32、33同士を連通させる。
【0024】
上記のように、本発明の密封容器における閉鎖部の構成はとくに限定が無く、使用するまでは排出部材の内部と収納部との連通を阻止し、使用時に外力によって連通させうるものであれば、いずれの構成も採用しうる。また、前記の実施形態では、閉鎖部を連通させるときの外力を加える手段として、摘み片や摘みを用いており、それらは容器本体12の外部に突出させている。そのため操作しやすい。しかし容器本体12を構成するシートが、その上から摘み片を操作できるほど柔軟なものであれば、摘み片などを容器本体12の内部に入れておくこともできる。
【0025】
た、内径が排出部材13の空洞の内径よりも細いノズルを装着してもよい。さらにこれにチューブを連結するようにしてもよい。
【0026】
図4a〜cは容器本体の内部を隔壁で仕切った密封容器の実施形態を示している。図4aの密封容器34では、容器本体を構成する2枚のシート35の間に同様なシートからなる隔壁36が介在され、周縁部11で一緒に熱溶着されている。また隔壁36内側の端縁は、排出部材13の側面に熱溶着されている。このものは隔壁36で容器本体12の内部が2室に分割されているので、それぞれの室37、38に別の種類の内容物を混合しないように充填しておくことができる。そのため、2液タイプの染毛剤や、2液タイプの接着剤など、充填時には分離して保管しておき、使用時に初めて混合する2液を充填するために利用しうる。前述した混合により蒸気圧を発生するタイプの内容物も、このような密封容器34に充填するのが好ましい。前述のように、2液を排出部材内で混合し、この状態で出してもよいが、排出部材を分割し、2液を別々に吐出してもよい。
【0027】
このような隔壁36を設ける場合は、排出部材13が安定し、容器全体の形状保持性も高まる。また、このような利点があるため、同一の内容物を充填してもよい。このものに図1の閉鎖部を設ける場合は、摘み片14を捻って開封することもできるが、隔壁36が設けられている側と反対側が開くように、排出部材13を折り曲げるほうが容易に弱め線15を破断しうる。それにより開放された排出部材13の開口は、いずれの室37、38とも連通し、排出部材13の内部で2種類の内容物が混合され、その後、先端の開口から吐出される。なお隔壁36を1枚のシートとし、その中央部を排出部材13の片面に熱溶着してもよいが、その場合は弱め線に対応する部位に窓をあけるなどにより、閉鎖部の開封後における収納部Sと排出部材13の連通を確保する。
【0028】
図4bに示す密封容器40は、収納部を左右方向に仕切る隔壁36のほか、上下方向に仕切る隔壁41を有し、全体として4つの室に分割している。そのため4種類の内容物を充填しておくことができる。なお、3室あるいは5室以上に分割することもできる。
【0029】
図4cは排出部材13を隔壁として利用する場合の実施形態を示している。すなわちこの密封容器43では、隔壁用のシートを用いず、容器本体12を構成する2枚のシート35の中央部をそれぞれ排出部材13の上面および下面に液密に熱溶着している。そのため、部品を節約することができ、しかも容器全体の形状保持性が高くなる。なおシート35と排出部材13を広い幅で熱溶着する場合は、捻りや折り曲げにより弱め線を破断するのが難しくなるので、図3cに示す閉鎖部30などを採用するのが好ましい。
【0033】
前記実施形態では、いずれも2枚のシートを重ね合わせて周縁部を熱溶着して扁平な袋状に構成しているが、襠部を設け、厚みがある袋の形態とすることもできる。その場合は内容量が多くなる
【0037】
に示す密封容器60は、周縁部11を熱溶着した2枚のシートからなる容器本体12と、その内部に収容した柔軟なシートを筒状に形成した排出部材13とから構成している。排出部材13の材質は、容器本体12とおなじものが用いられる。他の構成は、図1の密封容器の場合と同じである。このものは排出部材13が柔軟なシートから構成されているので、密封状態では内容物の圧力、とくに蒸気圧を有する内容物で圧縮されて扁平になっている。そして閉鎖部61を開放すると、内容物が排出部材13を拡げながら通過し、その先端部13bの開口から外部に噴出する。したがって内容物の噴出は比較的ゆっくりと行われる。
【0038】
前記実施形態では、排出部材はほぼ同径の筒状としているが、途中に断面積が大きい部分を設けてもよい。その場合は排出部材のバッファ効果が一層大きくなる。また、閉鎖部を開放したときの容器本体と排出部材の連通部の断面積を排出部材の断面積よりも小さくしておく場合も、バッファ効果が大きくなる。さらに排出部材の先端に、内径が小さいノズルを設けてもよい。その場合は内容物の噴出方向が安定する利点がある。

BACKGROUND OF THE INVENTION
The present invention relates to a sealed container.
[0002]
[Prior art]
Lunch boxes that have been marketed in the past may have a small bag filled with soy sauce, mayonnaise, or dressing. As shown in FIG. 6 , such a bag has two sheets 101 made of synthetic resin such as polyethylene or polypropylene, and is sealed by thermally welding the peripheral portion 102. A cut 103 is provided in a part that has been heat-welded, and the contents are taken out by cutting a part of the bag 100 from the cut 103 during use. In this product, the cut is made from the cut 103 and the contents are taken out by pressing the bag 100 with a finger. However, if the cut 103 is cut while the bag 100 is pressed, the contents may be scattered in an unexpected direction. Therefore, when opening such a bag, it is necessary to cut the cut 103 without pushing the bag 100 as much as possible, such as picking the peripheral edge portion 102.
[0003]
Further, in the case of a bag filled with a content that vaporizes at room temperature or a content having vapor pressure, the content pops out from the cut 103 even if the bag 100 is opened without being pushed. Therefore, there are procedures such as opening the cut 103 with the contents 103 facing the container and opening it carefully, or opening the cut 103 with the cut 103 facing upward, releasing only the gas, and then opening the gas greatly. is necessary.
[0004]
On the other hand, as shown in FIG. 7, there is a type in which a narrow passage 104 having a closed tip is provided at a corner portion of the bag 100 and a cut 103 is provided so as to cut the middle of the passage. After this is cut like an imaginary line, the contents jump out in the direction of the passage 104. Therefore, there is an advantage that the container is easily received. However, the point that the contents jump out from the cut immediately after cutting is the same as the case described above, and the possibility of polluting the surroundings has not been sufficiently solved.
[0005]
[Problems to be solved by the invention]
The present invention provides a sealed container that does not spout immediately after opening even if it is opened in a state where it is accidentally pressed with a finger, and even if the contents have vapor pressure, and therefore has a low risk of splashing around. This is a technical issue.
[0006]
[Means for Solving the Problems]
The sealed container according to the present invention (Claim 1) includes a bag-like container main body formed of two sheets and a discharge member provided in the container main body, and a distal end portion of the discharge member opens to the outside. And
The discharge member has a closed portion that is not always communicated with the inside of the container body at a position away from the distal end portion thereof, and is opened and communicated by an external force, and the closed portion is in the vicinity of the proximal end portion of the discharge member. There is provided a weakening line that breaks by bending and twisting , or a weakening line that breaks by bending or twisting, and a pinch piece sandwiched between the two sheets is provided at the base end of the discharge member It is characterized by being provided.
A second aspect of the sealed container of the present invention (Claim 2) is a bag-shaped container body composed of two sheets, a discharge member installed in the container body, and a plug connected to the discharge member. consists of a, the discharge member includes a distal end which opens to the outside of the container body, is arranged on the inner portion of the container body, and an open proximal end, said plug of said two sheets A pinch piece is provided between the plug and the plug is connected in a liquid-tight manner to the opening of the base end, and when the plug is removed from the base end, the inside of the discharge member and the container It is characterized by communication within the body .
A third aspect (Claim 3) of the sealed container of the present invention is a bag-shaped container body composed of two sheets, a discharge member installed in the container body, and a plug connected to the discharge member. The discharge member has a distal end portion that is open to the outside of the container body, and a proximal end portion that is disposed inside the container body and is open, and the plug includes a gap between the two sheets. The plug is connected to the opening of the base end portion in a liquid-tight manner, and the base end portion of the discharge member is formed in a cylindrical shape. Is configured in a cylindrical shape, and the plug is rotatably fitted to the opening of the base end portion and is fitted in a liquid-tight state. The plug and the base end portion are respectively specified. It is characterized in that the rotational position in the discharge member and the container body is provided with a window which communicates That.
[0007]
In such a container, the interior of the container body has a partition is at least two chambers by a partition wall, each chamber may be configured to communicate with the discharge member when opening the closure (claim 4 ). Furthermore, the interior of the container body and the partition are at least two chambers by the discharge member, each chamber may be configured to communicate with the discharge member when opening the closure (claim 5).
[0008]
[Operation and effect of the invention]
In the sealed container of the present invention (Claims 1 , 2 and 3 ), the discharge member is always closed by a closing portion or a plug, so that the inside of the container and the discharge member are not in communication. Therefore, even if the inside of the discharge member communicates with the outside through the opening of the tip portion, the inside of the container body is sealed. When the closing portion is communicated with an external force, the plug is removed from the base end portion, or the plug is rotated and communicated with the base end portion , the contents are not directly ejected to the outside. Get inside. Then, after the contents are accumulated in the discharge member to some extent, the contents come out from the opening of the discharge member. That is, in this sealed container, the discharge member functions as a buffer, and since there is a slight elapsed time from opening the closing part to discharging the contents from the tip of the discharge member, it suddenly jumps out of the discharge port. Absent. Therefore, the user can point the opening to the receiving tray in preparation for discharging the contents.

Since the discharge member is built in the container body and the tip of the discharge member opens to the outside at one end of the container body, the discharge member is built inside the container body. It can be shortened and is convenient for handling. Furthermore, the opening at the end of the container main body can be directed to the tray to be discharged with one hand, and the closing portion at a position away from the tip can be opened with the other hand, so that the operability is good.
[0010]
Further, in the sealed container according to claim 1, the closing portion is formed of a member provided in the vicinity of the proximal end portion of the discharge member and having a weakening line broken by bending and twisting , or a weakening line broken by bending or twisting . The base end portion of the discharge member can be easily broken by bending or twisting from the outside of the container main body, whereby the closing portion can be easily communicated.
[0011]
In the sealed container (Claim 4), the interior of the container body is partitioned into at least two chambers by a partition wall, and each chamber communicates with the discharge member when the closed portion is opened. Objects can be stored separately and can be mixed inside the discharge member during use. One room can be filled with one kind of contents. In the case of a sealed container in which a discharge member is housed inside the container, the discharge member can also be adopted as a partition that partitions the inside of the container main body (Claim 5). In this case, it is not necessary to prepare a separate partition wall, and the number of parts can be reduced. Furthermore, since the container body is reinforced and retained by the discharge member, it is stable even when a heavy content is stored.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the sealed container of the present invention will be described with reference to the drawings. 1 is a partially cutaway perspective view showing an embodiment of the sealed container of the present invention, FIGS. 2a and 2b are partially cutaway plan views and longitudinal sectional views of the sealed container of FIG. 1, and FIGS. FIG. 4a to c are cross-sectional views showing other embodiments of the sealed container of the present invention , and FIG. It is a partially notched perspective view which shows other embodiment of a sealed container.
[0013]
A sealed container 10 shown in FIG. 1 includes a bag-shaped container main body 12 composed of two sheets that are overlapped and thermally welded to a peripheral edge portion 11 and a cylindrical discharge member 13 that is built in the container main body. Has been. A space S between the two sheets in a range excluding the discharge member 13 inside the central portion of the container body 12 is a storage portion that is filled with contents .
[0014]
The sheet constituting the container body 12 is a flexible sheet made of synthetic resin, such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyethylene terephthalate, nylon, and the like that can be used for conventionally known sealed containers. Is used. Different types of materials, such as laminating a metal foil such as an aluminum foil having gas barrier properties, or laminating an outer layer film deposited with a metal such as aluminum, silica, carbon, etc. A laminate sheet obtained by laminating two or more films may be used. Further, the two sheets constituting the container body 12 are usually sheets of the same type of material, but different types of sheets may be used. Further, two sheets that are not thermally welded to each other may be used, and a film that can be thermally welded to both of them may be interposed between them. Further, an adhesive may be coated and adhered.
[0015]
The discharge member 13 is a cylindrical member having a distal end portion 13b opened and a proximal end portion 13a closed, and is made of a synthetic resin such as polyethylene, polypropylene, polyethylene terephthalate. Other materials such as metal and glass may be used. The discharge member 13 preferably has such a hardness that the hollow portion is not crushed by the internal pressure of the contents. However, it may be flexible or flexible (see FIG. 5 ). A flat tab 14 is integrally provided at the base end portion 13 a of the discharge member 13. The root portion 14a of the knob 14 is a lid of the discharge member 13 in this embodiment. On the outer periphery of the discharge member 13, it can be easily broken by bending or twisting at a position slightly closer to the distal end side from the base end portion 13 a, and before the break, the inside and outside of the discharge member 13 are hermetically sealed. An annular groove (weak line) 15 that maintains a liquid-tight state is formed. The weakening line 15 is the closing part of claim 1 and is arranged in the storage part S of the container body 12. In FIG. 1, the discharge member 13 has a circular cross-sectional shape, but may have an elliptical shape or a rectangular tube shape.
[0016]
As shown in FIGS. 2a and 2b, the vicinity of the proximal end portion 13a and the distal end portion 13b of the discharge member 13 are sandwiched between two sheets, respectively, to improve the airtightness and liquid tightness between the storage portion S and the outside. Heat welded or glued to maintain . Hysterectomy only piece 14 is sandwiched rare in the two sheets. Heat welding may be performed, and the adhesion between the discharge member 13 and the sheet becomes strong, and the operation becomes easy. Further, when the knob 14 is twisted, the thermal welding between the sheet and the discharge member 13 is difficult to peel off.
[0017]
In order to fill the sealed container 10 configured as described above, for example, one side of the peripheral edge 11 of the container body 12, for example, the lower side of FIG. Fill the contents, then heat weld and seal. As the contents, it is possible to employ any of the conventional fillings in bags, such as dressings, lotions, liquids such as shampoos and rinses, and creams such as mayonnaise.
[0018]
As shown in FIG. 2 b, the sealed container 10 filled with the contents and sealed has the storage portion S blocked from the outside. In order to open the sealed container 10, for example, the tip 13b or the center of the discharge member 13 is picked from the top of the container body 12 with one hand, and the pick piece 14 is picked and twisted with the other hand. If it does so, the discharge member 13 will be fractured | ruptured in the position of the weak line 15 of FIG. 2, and it will isolate | separate into the base end part 13a side and the front-end | tip part 13b side. In addition, since the container main body 12 has flexibility, when twisting the knob | pick piece 14, it does not get in the way so much. Even after complete separation by the weakening line 15, the knob 14 and the base end portion 13 a are sandwiched between the container main bodies 12, so that they do not fall out and are attached to the container main body 12. However, since the portion of the weak line 15 once separated does not have a sealing action, the contents enter the inside of the discharge member 13 through the opening 16 generated by the breakage of the discharge member 13 as indicated by an arrow P.
[0019]
However, since the inside of the discharge member 13 has been hollow until then, even if the contents enter the cavity, the discharge member 13 is not immediately ejected from the opening of the tip portion 13b. And after some time has passed, the contents flow out of the opening. Therefore, the user can concentrate on the work when twisting the knob 14, and after breaking the discharge member 13 with the weakening line 15, the user can concentrate on pouring the contents from the opening to a tray or the like. Even if the contents are once in the discharge member 13 even after the breakage, a buffering effect is obtained. Therefore, even if there is an internal pressure, there is no possibility of being ejected together with the breakage.
[0020]
Therefore, the contents include components having a low vapor pressure at normal temperature such as water and alcohol, but also components having a vapor pressure at normal temperature such as butane, pentane and hexane, or components that generate a vapor pressure when mixed. May be. When a component having a vapor pressure is included, it is preferable that the component, a component blended together with the component, and the container body are cooled before filling. Even those having such a vapor pressure are not ejected after opening. In addition, the internal pressure generated by the vapor pressure may be effectively used and ejected with the pressure of the contents. Specific examples of the contents include water, lower alcohols, polyhydric alcohols, silicone oils, hydrocarbon oils, ester oils, hair treatment agents, set agents, matting agents, hair dyes, hair removal agents, etc. , Emollients, moisturizers, exfoliants, bactericides, disinfectants, cleansing agents, shaving agents, antiperspirants, antiphlogistics, pest repellents, lotions, colons, deodorants, whitening agents, etc. For example, those obtained by dissolving or dispersing active ingredients such as those for use, and those obtained by blending these with ingredients having the above-mentioned vapor pressure. Moreover, a surfactant, a thickener, etc. can be mix | blended according to a discharge form (mist, foam, cream, gel).
[0021]
In the sealed container 10 of FIG. 1, the closed portion is formed by the annular groove 15 formed in the vicinity of the base end portion 13 a of the discharge member 13, but when it is broken by bending, the upper surface side or the lower surface side of the discharge member 13 A linear groove may be formed in both, and may be formed in both. Moreover, you may form a weak line in a side surface side. Further, as shown in FIG. 3a, the discharge member 13 is separated in advance from the proximal end portion side 21 and the distal end portion side 22, the end surfaces 21a and 22a are brought into contact with each other, and the gap is made of aluminum foil. It may be sealed with a sheet 23 that can be easily broken.
[0022]
The closing part 25 shown in FIG. 3b opens the base end part 13a of the discharge member 13, and plugs a plug 27 into the opening part 26 in a liquid-tight state. A knob 28 is integrally provided at the end of the plug 27. In this case, when the knob 28 is picked and the plug 27 is pulled out from the proximal end portion 13 a of the discharge member 13, the inside of the discharge member 13 and the storage portion S of the container body 12 communicate with each other through the opening 26.
[0023]
In the closing part 30 shown in FIG. 3c, the base end part 13a of the discharge member 13 is formed in a cylindrical shape, and a cylindrical plug 31 is fitted in the inside thereof in a liquid-tight state. The proximal end portion 13a of the discharge member 13 and the plug 31 are formed with windows 32 and 33 that communicate with each other at specific rotational positions. Normally, the plug 31 is locked at a position where the windows 32 and 33 do not communicate with each other, and the plug 31 is rotated during use so that the windows 32 and 33 communicate with each other.
[0024]
As described above, the structure of the closed portion in the sealed container of the present invention is not particularly limited as long as it prevents communication between the inside of the discharge member and the storage portion until it is used, and can be communicated by external force during use. Any configuration can be adopted. Further, in the above-described embodiment, a knob or a knob is used as means for applying an external force when the closing portion is communicated, and these are protruded to the outside of the container body 12. Therefore, it is easy to operate. However, if the sheet constituting the container body 12 is flexible enough to operate the knob from above, a knob or the like can be placed inside the container body 12.
[0025]
Also, the inner diameter may be fitted with a fine nozzle than the inner diameter of the cavity of the discharge member 13. Furthermore, you may make it connect a tube to this.
[0026]
4a to 4c show an embodiment of a sealed container in which the inside of the container body is partitioned by a partition wall. In the sealed container 34 of FIG. 4 a, a partition wall 36 made of a similar sheet is interposed between two sheets 35 constituting the container body, and is thermally welded together at the peripheral edge portion 11. The inner edge of the partition wall 36 is thermally welded to the side surface of the discharge member 13. Since the inside of the container main body 12 is divided into two chambers by a partition wall 36, the chambers 37 and 38 can be filled with different types of contents so as not to be mixed. Therefore, it can be used for filling two liquids such as a two liquid type hair dye and a two liquid type adhesive that are separated and stored at the time of filling and mixed for the first time at the time of use. It is preferable that such a sealed container 34 is filled also with the content of the type that generates a vapor pressure by mixing. As described above, the two liquids may be mixed in the discharge member and discharged in this state, but the discharge member may be divided and the two liquids may be discharged separately.
[0027]
When such a partition wall 36 is provided, the discharge member 13 is stabilized, and the shape retaining property of the entire container is also improved. Moreover, since there exists such an advantage, you may fill the same content. 1 can be opened by twisting the knob 14, but it is easier to bend the discharge member 13 so that the side opposite to the side where the partition wall 36 is provided is opened. Line 15 can be broken. The opening of the discharge member 13 thus opened communicates with any of the chambers 37 and 38, and two types of contents are mixed inside the discharge member 13, and then discharged from the opening at the tip. The partition wall 36 may be a single sheet, and the central portion may be heat-welded to one side of the discharge member 13, but in that case, by opening a window at a portion corresponding to the weakening line, etc. Communication between the storage portion S and the discharge member 13 is ensured.
[0028]
The sealed container 40 shown in FIG. 4b has a partition wall 41 for partitioning in the vertical direction in addition to the partition wall 36 for partitioning the storage portion in the left-right direction, and is divided into four chambers as a whole. Therefore, four types of contents can be filled. It can also be divided into three or more rooms.
[0029]
FIG. 4 c shows an embodiment in which the discharge member 13 is used as a partition wall. That is, in this sealed container 43, the central part of the two sheets 35 constituting the container main body 12 is thermally welded to the upper surface and the lower surface of the discharge member 13 without using the partition sheet. Therefore, parts can be saved and the shape retention of the entire container is enhanced. When the sheet 35 and the discharge member 13 are heat-welded with a wide width, it is difficult to break the weakening line by twisting or bending, and therefore it is preferable to employ the closing portion 30 shown in FIG.
[0033]
In the above-described embodiment, the two sheets are overlapped and the peripheral edge portion is heat-welded to form a flat bag shape. However, it is also possible to form a bag having a thickness by providing a collar portion. In that case, the content increases .
[0037]
A sealed container 60 shown in FIG. 5 includes a container body 12 composed of two sheets with the peripheral edge portion 11 thermally welded, and a discharge member 13 in which a flexible sheet accommodated therein is formed into a cylindrical shape. . The material of the discharge member 13 is the same as that of the container body 12. Other configurations are the same as those of the sealed container of FIG. Since the discharge member 13 is composed of a flexible sheet, this is compressed and flattened by the content having the pressure of the content, particularly the vapor pressure, in a sealed state. When the closing portion 61 is opened, the contents pass while expanding the discharge member 13, and are ejected to the outside from the opening of the tip portion 13b. Therefore, the contents are ejected relatively slowly.
[0038]
In the said embodiment, although the discharge member is made into the cylinder shape of substantially the same diameter, you may provide a part with a large cross-sectional area in the middle. In that case, the buffer effect of the discharge member is further increased. Also, the buffer effect is increased when the cross-sectional area of the communication portion between the container main body and the discharge member when the closed portion is opened is smaller than the cross-sectional area of the discharge member. Further, a nozzle having a small inner diameter may be provided at the tip of the discharge member. In that case, there is an advantage that the ejection direction of the contents is stabilized.
