Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、飲み物等の液体が収容される密閉袋の自立容器に関するものである。
【０００２】
【従来の技術】
従来、この種の密閉袋としては、例えばジュース等の飲み物を充填するための密閉袋が知られている。図１１に示すように、可撓性を有する密閉袋５０には注ぎ口５１が取着されている。この注ぎ口５１は、密閉袋５０の外側面に形成された開口部５２に筒状をなす注ぎ口本体５３を貫通取着して構成されている。注ぎ口本体５３の両端外周にはフランジ部５３ａ，５３ｂが突設されている。密閉袋５０の内側におけるフランジ部５３ｂは、同密閉袋５０の内面に接着されている。両フランジ部５３ａ，５３ｂには注ぎ口本体５３の連通部５３ｃを閉塞するようにビニール製のシート状シール部材５４ａ，５４ｂが接着され、両シール部材５４ａ，５４ｂにより密閉袋５０内の飲み物が外部へ流れ出ないようになっている。
【０００３】
そして、この密閉袋５０から飲み物を注ぎ出すには、図示しないダンボール箱等からなる自立容器に収容された密閉袋５０を収容した後、注ぎ口本体５３に対し、同注ぎ口本体５３とは別部材からなる注ぎ管５５を差し込む。すると、注ぎ管５５にて両シール部材５４ａ，５４ｂが破られ、注ぎ管５５を介して密閉袋５０の内部と外部とが連通される。そして、自立容器を傾けると、密閉状態の解除された密閉袋５０の飲み物が注ぎ管５５から注ぎ出される。
【０００４】
【発明が解決しようとする課題】
ところが、従来技術に示す注ぎ口５１では、密閉袋５０に開口部５２を形成し、その開口部５２に対して注ぎ口本体５３を接着したり、その両フランジ５３ａ，５３ｂにシール部材５４ａ，５４ｂを接着するという面倒な加工が多く必要であった。又、注ぎ口本体５３以外にもシール部材５４ａ，５４ｂ、注ぎ管５５が必要で、部品点数が多かった。その結果、製造コストが上昇するという問題があった。更に、注ぎ口本体５３に注ぎ管５５を差し込んだ状態では、注ぎ管５５を介して密閉袋５０の内部と外部とは連通状態のままであるため、自立容器等が倒れたりすれば、飲み物が注ぎ出されてしまうという問題があった。
【０００５】
本発明の第１の目的は、密閉袋に対して容易に注ぎ口を組付けし得ることを目的とした。又、第２の目的は、部品点数を減らして製造コストの低減を図ることを目的とした。更に、第３の目的は、注ぎ口から飲み物が漏れるのを少なくすることにした。
【０００６】
【課題を解決するための手段】
請求項１に記載の発明は、可撓性の密閉袋内に充填されている液体を外部へ注ぎ出すための注ぎ口が取着された密閉袋を、開口部を介して収容する自立容器において、前記注ぎ口は、前記密閉袋の切り口を挟み込んだ状態で互いに重合可能な一対の挟持部材を備え、各挟持部材の両端同士を互いに接合して接合部とするとともに、同挟持部材の両端を除く中央付近を非接合部とし、前記接合部の両側上部に係合部を設けるとともに前記非接合部に開閉部を設け、前記挟持部材は開閉部を閉じる方向に弾性が付与され、この開閉部の内側に前記密閉袋の切り口を挟入取着可能とし、前記挟持部材の各両端が接近するのに伴い開閉部を開き、この開く動作に追従して前記開閉部の内側に挟入取着されている切り口を開くように構成し、前記開口部を塞ぐ蓋には、前記密閉袋の切り口が上向きになるように注ぎ口を支持可能な支持手段を設け、前記支持手段は、注ぎ口を挿入可能な挿入孔と、注ぎ口の接合部に設けられた係合部を上面に掛止支持可能な支持部材と、前記接合部に設けられた係合部が当接されることにより前記注ぎ口の開閉部が開いた状態及び閉じた状態にそれぞれ前記注ぎ口を保持する保持手段とを備えていることを要旨とするものである。この構成によれば、非接合部とされた開閉部の内側に密閉袋の切り口を挟入取着した後、挟持部材の両端に位置する接合部同士を接近移動させると、開閉部が開かれ、それに伴い切り口も開かれる。また、挿入孔に注ぎ口が挿入されると、支持部材に係合部が掛止支持され、注ぎ口が支持されると、密閉袋の切り口が上向きになるため、液体が漏れなくなる。しかも、保持手段により注ぎ口が開いた状態又は閉じた状態に保持される。
【０００７】
請求項２に記載の発明は、前記保持手段は、注ぎ口の開閉部が開いた状態のときに前記係合部が係合する第１の被係合部と、注ぎ口が閉じた状態のときに前記係合部が係合する第２の被係合部とから構成されていることを要旨とするものである。この構成によれば、注ぎ口が開くと、係合部が第１の被係合部に係合される。又、注ぎ口が閉じると、係合部が第２の被係合部に係合される。
【０００８】
請求項３に記載の発明は、前記挟持部材には折曲部が形成され、この折曲部は開閉部が開いたときに折曲可能とされていることを要旨とするものである。この構成によれば、開閉部が開かれる際には、折曲部が折曲される。
【０００９】
請求項４に記載の発明は、前記接合部の両側下部には抜止め突起が設けられていることを要旨とするものである。この構成によれば、自立容器を傾けた状態では、抜止め突起が蓋の裏面に当接されるため、注ぎ口が挿入孔から抜け出ることはない。
【００１３】
【発明の実施の形態】
以下、本発明を飲み物が収容される密閉袋の注ぎ口及び同袋の自立容器に具体化した一実施形態を図面を参照して説明する。
【００１４】
まず、密閉袋の注ぎ口について説明する。
図１〜図３に示すように、注ぎ口１は密閉袋２のコーナ部に対して斜めに取着可能とされている。この注ぎ口１は合成樹脂からなり、互いに重合可能な挟持部材としての挟持片３を一対備えている。両挟持片３の前後両端部は接着剤により接合されて接合部４とされ、前後両端部を除く中央付近は非接合部５とされている。非接合部５における両挟持片３の内側面には、密閉袋２のコーナ部が挟入されて接着剤により接合されている。そして、両挟持片３に接着されていない密閉袋２のコーナ部の先端を両挟持片３の上端縁に沿って切り取ることにより、図２に点線で示す切り口２ａとすることができる。
【００１５】
接合部４と非接合部５との境界において、両挟持片３の外側面には一対の第１の折曲部６が形成されている。この第１の折曲部６は断面Ｖ字状に形成され、密閉袋２の外縁に沿ってハ字状に拡がっている。又、非接合部５における両挟持片３の内側面には両挟持片３の幅方向に延びる第２の折曲部７が形成されている。この第２の折曲部７も断面Ｖ字状に形成されている。そして、図３，図４に示すように、両挟持片３の両端、すなわち両接合部４同士（同図の左右）を互いに接近移動させたとき、第１及び第２の折曲部６，７により、両挟持片３の非接合部５が密閉袋２の切り口２ａを開くように折曲されるようになっている。この両挟持片３の非接合部５間が密閉袋２を開閉可能な開閉部８となっている。そして、この開閉部８を閉じる方向に各挟持片３は弾性を有している。
【００１６】
又、両挟持片３の下端中央には切欠部９が形成され、その切欠部９の両端にはアーチ状をなす弾性片１０が一体に形成されている。この弾性片１０は前記開閉部８を閉じる方向に弾性を有している。前記接合部４の両側上部には係合部としての前方及び後方係合突起１１，１２が形成されている。又、接合部４の両側下部には抜止め突起１３が形成されている。挟持片３の前端（図１の手前側）に位置する抜止め突起１３は前方係合突起１１の真下に配置され、後端（図１の奥方）に位置する抜止め突起１３は後方係合突起１２の斜め下方に配置されている。又、接合部４の後部上端には把持部１４が上方へ突設されている。
【００１７】
次に、密閉袋２の自立容器について説明する。
図５に示すように、ダンボール紙からなる自立容器１５は側面五角形をなす箱状に形成され、その上部には開口部１６が形成され、この開口部１６を介して自立容器１５内に前記密閉袋２が収容される。開口部１６には蓋１５ａが設けられている。この蓋１５ａは開口部１６の前端縁を中心にして回動可能に取着され、後端には同蓋１５ａを閉じた状態に保持可能な図示しない留め部が形成されている。
【００１８】
図５，図６（ａ）に示すように、前記蓋１５ａは平坦面と傾斜面とを有し、その傾斜面には合成樹脂からなる支持部材としての支持プレート１７が設けられている。この支持プレート１７には挿入孔１８が形成され、同挿入孔１８を介して自立容器１５の内部と外部とは連通されている。そして、挿入孔１８には前記注ぎ口１を自立容器１５の内部から係入可能となっている。挿入孔１８は、その中央付近において菱形状をなす口出し部１８ａと、口出し部１８ａの両端から前後方向に延びる一対のスリット部１８ｂ，１８ｃとから構成されている。そして、挿入孔１８に注ぎ口１が挿入された状態で、支持プレート１７の上面に前記両係合突起１１，１２が掛止支持されることにより、同注ぎ口１を蓋１５ａに支持可能となっている。
【００１９】
前記後方スリット部１８ｃの両側における支持プレート１７の上面には、一対の挿通部１９が切欠き形成され、挿通部１９には前記後方係合突起１２が挿入可能となっている。挿通部１９の前後における支持プレート１７の上面には、第１及び第２の被係止突起２０，２１が形成されている。本実施形態では、前記第１及び第２の被係止突起２０，２１により保持手段が構成されている。
【００２０】
そして、図６（ｂ）に示すように、第１の被係止突起２０の前面に対して、前記注ぎ口１の後方係合突起１２が両折曲部６，７及び弾性片１０の弾性力に抗して当接されることにより、注ぎ口１の開閉部８は開いた状態に保持される。この状態において、前方スリット部１８ｂの前端は注ぎ口１の前方接合部４が当接可能な当接部２２となっている。又、図６（ｃ）に示すように、第２の被係止突起２１の後面に対して前記注ぎ口１の後方係合突起１２が当接されることにより、注ぎ口１の開閉部８は閉じた状態に保持される。この状態において、注ぎ口１の非接合部５は後方スリット部１８ｃに係入される。
【００２１】
次に、上記のように構成された密閉袋の注ぎ口及び同袋の自立容器の作用につついて説明する。
まず、注ぎ口１の開閉部８の内側面に接着剤を塗布した後、同開口部８を密閉袋５０のコーナ部に挟入して接着する。その後、密閉袋５０のコーナ部を鋏等で切り取り、切り口２ａを開口する。
【００２２】
次に、自立容器１５の蓋１５ａを開き、開口部１６を介して密閉袋２を収容する。その後、蓋１５ａを閉める方向へ倒しておき、注ぎ口１の前方係合突起１１を挿入孔１８の口出し部１８ａから蓋１５ａの外部へ抜き出し、前方スリット部１８ｂに注ぎ口１の接合部４を係入する。そして、前方係合突起１１を支持プレート１７の上面に当接する。
【００２３】
続いて、図７に示すように、把持部１４を把持しながら、注ぎ口１の後方係合突起１２を挿通部１９から蓋１５ａの外部へ抜き出す。そして、図６（ｃ）に示すように、後方係合突起１２を支持プレート１７の上面及び第２の被係止突起２１の後面に当接させる。すると、注ぎ口１の開閉部８は閉じた状態で、蓋１５ａの上面に掛止支持される。その後、蓋１５ａを閉め、注ぎ口１の上端縁に沿って密閉袋２のコーナ部を切り取ると、切り口２ａが開口される。この状態において、注ぎ口１の開閉部８は挟持片３及び弾性片１０の弾性力により、閉じられるとともに、注ぎ口１の非接合部５は後方スリット部１８ｃ内にて挟まれる。そのため、自立容器１５が万が一倒れても、密閉袋２内の飲み物が注ぎ口１を介して外部に勢いよく流れ出ることはない。
【００２４】
次いで、注ぎ口１の開閉部８を開けるには、把持部１４を把持しながら、後方係合突起１２と第２の被係止突起２１との当接を解除して、同後方係合突起１２を第１の被係止突起２０の前面及び支持プレート１７の上面に当接させる。すると、前方係合突起１１は支持プレート１７の上面を摺動しながら前方へ移動され、注ぎ口１の前方接合部４の前端が前方スリット部１８ｂの前端に当接される。そして、両挟持片３は第１及び第２の折曲部６，７にて折曲され、注ぎ口１の開閉部８が開いた状態に保持される。この開閉部８が開くと、密閉袋２の切り口２ａが開かれる。
【００２５】
ここで、支持プレート１７は斜め前方へ傾斜されているが、両挟持片３及び弾性片１０の弾性力が前後方向へ作用するため、後方係合突起１２は第１の被係止突起２０の前面に対して押圧される。そのため、注ぎ口１の開閉部８が閉じてしまうことはない。そして、図８に示すように、自立容器１５を傾けると、密閉袋２内の飲み物が注ぎ口１の開閉部８を介して注ぎ出される。又、自立容器１５を傾けた状態では、抜止め突起１３が蓋１５ａの裏面に当接されるため、注ぎ口１が挿入孔１８から抜け出ることはない。
【００２６】
本実施形態は以下に示す（１）〜（７）の効果を有する。
（１）密閉袋２に開口部を形成したり等の加工が不要になり、挟持片３の開閉部８に密閉袋２のコーナ部を挟入取着するだけでよいため、密閉袋２に対して容易に注ぎ口を組付けることができる。又、密閉袋２に開口部を形成し、その開口部に注ぎ口を取付ける場合のように密閉構造とするための部材や、注ぎ口に嵌め込む注ぎ管等の部材等が必要ない。その結果、部品点数を減少できるとともに、その密閉構造とするための加工も必要としないため、製造コストの低減を図ることができる。
【００２７】
（２）両挟持片３には第１及び第２の折曲部６，７を設けたため、開閉部８を開けるときには両挟持片３の非接合部５を容易に折り曲げることができる。又、第１の折曲部６を両挟持片３の外側面に形成し、第２の折曲部７を両挟持片３の内側面に形成したため、開閉部８を開けるときには両挟持片３の非接合部５を互いに離間する方向へ折り曲げることができ、開閉部８を確実に開けることができる。
【００２８】
（３）両挟持片３には開閉部８を閉じる方向に弾性付与したため、例えば、密閉袋２に収容されていない場合に注ぎ口１が下側を向いても、密閉袋２の切り口２ａから勢いよく飲み物が漏れるのを防止できる。しかも、両挟持片３の下端中央には開閉部８を閉じる方向に弾性を有する弾性片１０を設けたため、同弾性片１０と前記両挟持片３の弾性力により、開閉部８をより一層開きにくくできる。この結果、密閉袋２の切り口２ａから漏れる飲み物の量をより一層少なくすることができる。
【００２９】
（４）支持プレート１７の上面に注ぎ口１の両係合突起１１，１２を掛止支持して注ぎ口１を支持したため、密閉袋２の切り口２ａが下向きになることはない。この結果、注ぎ口１から飲み物が漏れるのを防止することができる。しかも、注ぎ口１の前後に両係合突起１１，１２を設けたため、注ぎ口１が支持されている状態ではその両端ががたつかず、安定した状態で注ぎ口１を支持することができる。
【００３０】
（５）前方スリット部１８ｂの当接部２２に注ぎ口１の前方接合部４の前端面を当接させ、注ぎ口１の後方係合突起１２を第１の被係止突起２０の前面に当接させて注ぎ口１を開く状態に保持可能にした。そのため、使用者が注ぎ口１を把持して開けた状態に保持しなくても、自立容器１５を傾けるだけで密閉袋２の切り口２ａから飲み物を容易に注ぎ出すことができる。
【００３１】
（６）両挟持片３と弾性片１０との弾性力により、前方スリット部１８ｂの当接部２２及び第１の被係止突起２０に対して注ぎ口１を押圧した。そのため、自立容器１５を傾けても注ぎ口１の開き状態が簡単に解除されることはない。
【００３２】
（７）第２の被係止突起２１の後面に対して注ぎ口１の後方係合突起１２を当接させて注ぎ口１の開閉部８を閉じた状態に保持可能にした。そのため、自立容器１５が傾いたり、倒れたりして注ぎ口１が下側を向いても、密閉袋２の切り口２ａから勢いよく飲み物が漏れるのを防止できる。
【００３３】
なお、本発明は前記実施形態以外に以下のように構成してもよい。
（ａ）図９に示すように、両挟持片３の非接合部５の両側に斜め外方へ向けて一対の突起２５を形成してもよい。この構成にすれば、両挟持片３の両端を把持するとともに、両突起２５を把持すれば、注ぎ口１の開閉部８を容易に開くことができる。
【００３４】
（ｂ）前記実施形態では、後方係合突起１２を第２の被係止突起２１に支持して注ぎ口１の開閉部８を閉じた状態に保持するようにしたが、図１０に示すように、口出し部１８ａの上方に閉じ部材２６を設けてもよい。この閉じ部材２６は、支持プレート１７の上面に固着された可撓性を有する一対の脚部２６ａと、同脚部２６ａの先端において逆チャンネル状に形成されたキャップ部２６ｂとから構成されている。そして、注ぎ口１の開閉部８が閉じ状態に保持されているときは、前記キャップ部２６ｂを両挟持片３の非接合部５の上端に挟入する。この構成によっても、自立容器が倒れても、注ぎ口１の開閉部８から飲み物が漏れるのを確実に防止することができる。
【００３５】
（ｃ）前記実施形態では、第１及び第２の被係止突起２０，２１に対して後方係合突起１２を当接可能にしたが、第１及び第２の被係止突起２０，２１の代わりに後方係合突起１２を係入可能な凹部を形成してもよい。
【００３６】
（ｄ）前記実施形態では、別部材からなる挟持片３を接合したが、単一の部材からなる挟持片３をその中央部で折り曲げ、同挟持片３の両端部を接着剤で接合してもよい。又、接着剤で両挟持片３の両端部を接合する以外に、ビスとナットで締付けたり、超音波溶着等で接合するようにしてもよい。
【００３７】
（ｅ）前記実施形態では、注ぎ口１を開いた状態又は閉じた状態の何れか一方の状態で選択的に保持可能な自立容器１５とした。これ以外にも、第１又は第２の被係止突起２０，２１のうち何れかを省略して、注ぎ口１を開いた状態のみ又は閉じた状態のみで保持する構成にしてもよい。
【００３８】
（ｆ）前記実施形態では、自立容器１５をダンボール紙からなる材質としたが、合成樹脂や金属製からなる材質に変更してもよい。この構成によれば、耐水性及び剛性を高めることができ、自立容器１５を何度も繰り返して使用できる。
【００３９】
（ｇ）前記実施形態では、自立容器１５の形状を側面五角形をなす箱状に形成したが、任意の形状に変更してもよい。
（ｈ）前記実施形態では、飲み物が収容される密閉袋２に具体化したが、液体であれば、任意のものを収容してもよい。
【００４３】
【発明の効果】
請求項１に記載の発明によれば、密閉袋に対して注ぎ口を容易に組付けることができる。又、部品点数を減らして製造コストの低減を図ることができる。さらに、注ぎ口を安定した状態で支持することができ、注ぎ口から液体が流れ出るのをより一層防止できる。しかも、使用者が注ぎ口を開いた状態に保持することなく、液体を注ぎ出すことができる。又、自立容器が傾いたり、倒れたりしても注ぎ口から液体が流れ出るのを防止できる。
【００４４】
請求項２に記載の発明によれば、請求項１に記載の発明の効果に加え、注ぎ口を開いた状態で確実に保持でき、又は閉じた状態で確実に保持することができる。

Then, as shown in FIG. 6B, the rear engagement protrusion 12 of the spout 1 is elastic to the bent portions 6 and 7 and the elastic piece 10 with respect to the front surface of the first locked protrusion 20. By being abutted against the force, the opening / closing portion 8 of the spout 1 is held open. In this state, the front end of the front slit portion 18b is a contact portion 22 with which the front joint portion 4 of the spout 1 can contact. Further, as shown in FIG. 6C, the rear engaging protrusion 12 of the spout 1 is brought into contact with the rear surface of the second locked protrusion 21, whereby the opening / closing portion 8 of the spout 1. Is kept closed. In this state, the non-joining part 5 of the spout 1 is engaged with the rear slit part 18c.
[0021]
Next, the operation of the spout of the sealed bag and the self-supporting container of the bag configured as described above will be described.
First, an adhesive is applied to the inner surface of the opening / closing part 8 of the spout 1, and then the opening 8 is sandwiched and bonded to the corner part of the sealed bag 50. Then, the corner part of the airtight bag 50 is cut off with a scissors etc., and the cut opening 2a is opened.
[0022]
Next, the lid 15 a of the self-supporting container 15 is opened, and the sealed bag 2 is accommodated through the opening 16. Thereafter, the lid 15a is tilted in the closing direction, the front engaging projection 11 of the spout 1 is extracted from the outlet 18a of the insertion hole 18 to the outside of the lid 15a, and the joint 4 of the spout 1 is connected to the front slit 18b. Enroll. Then, the front engaging protrusion 11 is brought into contact with the upper surface of the support plate 17.
[0023]
Subsequently, as shown in FIG. 7, the rear engagement protrusion 12 of the spout 1 is extracted from the insertion part 19 to the outside of the lid 15 a while holding the holding part 14. Then, as shown in FIG. 6C, the rear engagement protrusion 12 is brought into contact with the upper surface of the support plate 17 and the rear surface of the second locked protrusion 21. Then, the opening / closing portion 8 of the spout 1 is closed and supported on the upper surface of the lid 15a. Then, when the lid 15a is closed and the corner portion of the sealed bag 2 is cut along the upper edge of the spout 1, the cut 2a is opened. In this state, the opening / closing part 8 of the spout 1 is closed by the elastic force of the sandwiching piece 3 and the elastic piece 10, and the non-joining part 5 of the spout 1 is sandwiched in the rear slit part 18c. Therefore, even if the freestanding container 15 falls down, the drink in the sealed bag 2 does not flow out through the spout 1 vigorously.
[0024]
Next, in order to open the opening / closing part 8 of the spout 1, the gripping part 14 is gripped, the contact between the rear engagement protrusion 12 and the second locked protrusion 21 is released, and the rear engagement protrusion 12 is brought into contact with the front surface of the first locked protrusion 20 and the upper surface of the support plate 17. Then, the front engagement protrusion 11 is moved forward while sliding on the upper surface of the support plate 17, and the front end of the front joint portion 4 of the spout 1 is brought into contact with the front end of the front slit portion 18b. And both the clamping pieces 3 are bent by the 1st and 2nd bending parts 6 and 7, and the opening-and-closing part 8 of the spout 1 is held in the open state. When the opening / closing part 8 is opened, the cut 2a of the sealed bag 2 is opened.
[0025]
Here, although the support plate 17 is inclined obliquely forward, the elastic force of the sandwiching pieces 3 and the elastic piece 10 acts in the front-rear direction, so that the rear engagement protrusion 12 is the first engagement protrusion 20. Pressed against the front. Therefore, the opening / closing part 8 of the spout 1 is not closed. Then, as shown in FIG. 8, when the self-standing container 15 is tilted, the drink in the sealed bag 2 is poured out through the opening / closing part 8 of the spout 1. Further, when the self-supporting container 15 is tilted, the retaining protrusion 13 is brought into contact with the back surface of the lid 15 a, so that the spout 1 does not come out of the insertion hole 18.
