Description

【０００１】
【発明の属する技術分野】
本発明は、容易に開封できる、いわゆる易開封包装体及びこれを製造するための充填包装装置に関するものである。
【０００２】
【従来の技術】
この種の包装体は、フィルムを筒状にして重ね合せ部を形成し、該重ね合せ部の領域内で該重ね合せ部の側縁に沿った方向（縦方向）で溶着して形成されるシール部（以下「縦シ−ル部」という）を有する筒体とし、内容物を筒体内に充填した後に該側縁に沿う方向での所定間隔位置で該側縁に対して直角な方向に横シール部が形成されることにより、得られる。
【０００３】
上記縦シール部は種々の形態で成される。例えば、合掌貼り、通常の封筒貼り、内側折返し部を有する封筒貼り等である。その一例として、特公平６−６２１３１に合掌貼りが開示されている。この合掌貼りでは、フィルムの側縁部が内側面同士で合さるように重なるようにして重ね合せ部が形成され、一定幅で側縁を除いて該側縁に沿って連続してシールされる。この包装体の開封に際しては、上記側縁の摘み部である非シール部で両フィルムを指で摘んで拡げることによって、上記縦シール部を分離せしめる。かくして、内容物を取り出せるようになる。

【発明が解決しようとする課題】
通常、包装体は、開封前にあってはそのシールはシール強度が高く不用意に開いてしまわないことが望まれ、又、開封時にあっては容易に開封できることが望まれる。すなわち、シール強度に関し相反する条件が求められる。これは、シールされている包装体がいずれ開封される以上は、どの包装体についても望まれることである。上述の公知の特公平６−６２１３１においても例外ではない。この公知の包装体では、縦シールは縦方向に一様に連続しているので、シール強度を上げればシール性は向上するが、簡単には開封できず、又、シール強度を下げれば簡単に開封できるが、開封前の取扱い時に不用意に開いてしまうことがある。
【０００５】
本発明は、このような、相反する要求を満足させるような、シール強度を確保し開封し易い包装体を提供し、又、そのための充填包装装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
本発明によれば、上記目的は、易開封包装体に関しては、フィルムを筒状にして重ね合せ部を形成し、該重ね合せ部の領域内で該重ね合せ部の側縁に沿った方向に溶着して形成される縦シール部を有する筒体とし、内容物を筒体内に充填した後に該側縁が延びる方向での所定間隔位置で該側縁に対して直角な方向に横シール部が形成された包装体において、縦シール部は上記側縁と平行に連続して形成される主シール部と、該主シール部に沿って不連続に形成される副シール部とを有し、単位シール面積当りの溶着強度は副シール部の方が主シール部よりも大きくなっていることにより達成される。
【０００７】
かかる包装体は、主シール部によって連続的にシールされているので、内容物の洩出は防止され、そのシール強度は或る程度確保される。本発明では、これに加えて、溶着強度の高い副シール部が、不連続に形成されており、それによって全体のシール強度は十分なものとなる。したがって、意図しないときに不用意に開いてしまうことはない。開封時には、シール方向の一端側から開かれるので、不連続な副シール部では、スナップを一つづつ外すように、次々と衝撃的に分離される。これは、作業者にとって大した負担とならない。主シール部は比較的分離しやすいシール強度なので、上記副シール部に加え主シール部も同時に分離してもそのために作業者に許容される力の範囲内である。
【０００８】
本発明の易開封包装体において、副シール部は主シール部の領域内にあって該主シール部と重なって形成されていても、主シール部に近接した位置に形成されても良い。どちらでも、同様の効果を得る。又、副シール部は、縦方向で定間隔位置で点状もしくは線状に溶着されることができる。
【０００９】
本発明は、重ね合せ部が、合掌貼り溶着、封筒貼り溶着、内側折返し部を有する封筒貼り、外側折返し部を有する封筒貼り、そして、合掌合せ部を包装体面に折り合わせた溶着のいずれであっても適用できる。その際、重ね合わせ部が上記内側あるいは外側折返し部を有する封筒貼りであり、副シ−ルが主シ−ルに近接して形成される場合には、該副シールは折返部の範囲内にあることが好ましい。
【００１０】
さらに本発明によれば、上記目的は、易開封包装体を製造するための充填包装装置に関し、走行中の帯状のフィルムを案内しながら両側部で重ね合せ部を形成して筒状にするフォーミングプレート装置と、該フィルムを重ね合せ部にて溶着して筒体を形成する縦シール装置と、該筒体の内部へ先端が進入している内容物充填のためのノズルと、内容物充填後の筒体を所定間隔位置で区分するようにシールする横シール装置とを備えている充填包装装置において、縦シール装置はフィルムを走行方向で連続してシールする主シール装置と、同方向で不連続位置でシールする副シール装置とを備え、副シール装置は単位シール面積当りの溶着強度が主シール装置よりも大きく設定されていることにより達成される。
【００１１】
上記主シール装置と副シール装置とは、フィルムの走行方向にて、どちらが上流側に位置していても良い。
【００１２】
主シール装置と副シール装置の少なくとも一方がシールの際の溶着強度を可変とする制御装置に接続されていることとが望ましい。これにより、主シール部と副シール部とのシール強度の相対関係が、包装形態あるいは要求シール性そして要求易開封性に対応容易となる。
【００１３】
本発明の縦シール装置は、溶着形態自体としてはすでに公知の超音波シール装置、抵抗加熱装置、高周波誘電加熱シール装置、熱風シール装置、溶融樹脂粒シール装置のいずれにも適用可能である。
【００１４】
なお、実公昭４６−３６２３２には縦シール部に沿って切除孔若しくは切除線が形成されているものが開示されているが、これは、シール部を補強するという機能がなく、本願発明の副シールとは全く異なる。
【００１５】
【発明実施の形態】
以下、添付図面にもとづいて本発明の実施の形態を説明する。
【００１６】
図１においては、１はフォーミングプレートであり、２Ａ，２Ｂ，２Ｃ等のガイドローラ２により定速で送られてくる帯状フィルムＦが、このフォーミングプレート１で筒状に巻き込まれた後に、側部の重ね合せ部Ｆ２が合掌貼りの形態で形成されつつ送られながら縦シール装置３にて溶着されてフィルムの筒体Ｆ１が形成される。図２によく見られるように、縦シール装置３は後に詳述する。超音波溶着によるシール装置として図示されているが、該縦シール装置は超音波溶着に限らず、抵抗加熱溶着、高周波誘電加熱溶着、熱風溶着、溶融樹脂の粒を吹き付ける（ｂｅａｄ ｓｅａｌ）溶着等による他の公知のシール装置でもよい。この縦シール装置３については後に詳述する。
【００１７】
フォーミングプレート１の直下には、図1に示すごとく、筒体Ｆ１の断面形状を所定形状とするための三種の４Ａ，４Ｂ，４Ｃのリング状のガイド４が配設されていて筒状Ｆ１を走行案内している。ガイド４は、上流位置のもの４Ａが円形をなし下流位置のもの４Ｃは紙面に直角な方向に延びた長円形状をなしており、筒体Ｆ１を偏平に導く下流位置のガイド４Ｃを通過して筒体Ｆ１は偏平状に引き出されている。
【００１８】
上記ガイド４の下流位置には、圧接する対ローラ５Ａ，５Ｂから成る送りローラ５が紙面の直角方向の両側に二対配されており、筒対Ｆ１の両側縁部を挟圧しながら定速で下流方向に送り出している。一方、上記二対の送りローラ５，５の間には、ホッパ６に収容されている内容物を充填ポンプ７によって上記筒体Ｆ１内に連続して充填するためのノズル８が延びている。該ノズル８は先端部分が紙面に直角に延びる矩形断面の開口となっている。
【００１９】
上記ノズル８の先端に対して上流下流方向に位置する範囲でその両脇には、無端状に走行するダンパーベルト９が設けられており、フィルムの筒体Ｆ１に内容物が充填されてなる充填物を両脇から圧して偏平断面のものとしている。符号１０，１１は圧延ローラで、ダンパーベルト９で偏平化された充填物の送り方向での単位長さ当りの内容物の充填量が所定値となるような厚さに充填物を圧延するためのものである。該二つの圧延ローラ１０，１１の間には、水平方向に無端状に走行する送り出しコンベア１２が設けられていて、偏平化された連続的な充填物の送り方向を水平方向に変向している。該送り出しコンベア１２の下流側にはローラコンベア１３が配設されており、さらにその下流直後の位置にしごき手段としての一対のしごきローラ１４，１４が設けられている。該しごきローラ１４，１４はそれぞれ軸１５，１５まわりに揺動自在なアーム１６，１６の先端に取付けられており、上記アーム１６，１６の間欠的揺動開閉によって、偏平化された充填物を挟圧して、その流れ方向で所定間隔位置に内容物の存在しないしごき部を形成するようになっている。
【００２０】
上記しごきローラ１４，１４の下流位置には、図１に示されるように、同一構造の二つの金型１７，１８が配設されている。この二つの金型１７，１８は、上流・下流の両方向（図１の矢印方向）に往復移動可能になっている。例えば、図1の場合、上流位置にある金型１７が開から閉の状態となって下流方向へ充填物の送り速度と同一速度で、開状態の下流の金型１８の図示の位置まで移動するようになっている。一方、開状態の金型１８は金型１７よりも大きな速度で、上記閉状態の金型１７が図示されている位置まで戻る。このように、両金型は下流方向に向かうときには閉じてそして上流方向に向かうときには開いて互にその位置を入れ替えるように移動するようになっている。
【００２１】
フォーミングプレート１からしごきローラ１４，１４までの工程は、地面に対して上下方向、水平方向、傾斜方向またはこれらの組み合わせでも良く、例えば粘稠液体や固形物を含む液体や低粘度液体など内容物の特性に応じて適宜選択できる。
【００２２】
上記二つの金型１７，１８には、上流から下流に向け樹脂等の搬送ベルト１９が貫通している。該搬送ベルト１９はローラ２０Ａ，２０Ｂ，２０Ｃ，２０Ｄによって無端状に張設せられ、特にローラ２０Ｄは引張りばね２１によって付勢されており、常に上記搬送ベルト１９が緊張せられるようになっている。かくして、搬送ベルト１９は、上記金型１７内で充填物の成形時には、上記引張りばね２１に抗して金型内壁に沿って変形可能で、成形が完了して金型１７が開いたときには元の緊張状態に戻ることができる。
【００２３】
図１において、上記搬送ベルト１９の下流位置には挟圧コンベア３２が設けられている。さらに、その下流には搬送ベルトコンベア３３が設けられ、該搬送ベルトコンベア３３の上方には、下流方向に搬送ベルトコンベア３３と同速度で移動し上流方向に早戻りする支持体３６によって上下動可能に支持された分離装置３４，３５が設けられている。該分離装置３４，３５は支持体３６の下流方向への移動時に降下して充填物のしごき部を二本の平行な線で横シールしかつその二本の横シール線の中間で切断するように搬送ベルトコンベア３３と同期している。
【００２４】
次に、前記縦シール装置３について、図２を参照しつつ詳述する。この縦シール装置３は、フォーミングプレート１により筒状にされたフィルムの筒体Ｆ１の側部に形成された重ね合せ部Ｆ２を溶着するための主シール装置４１と副シール装置４２とを有している。この主シール装置４１と副シール装置４２の前後には、上記重ね合せ部Ｆ２を挟圧しながら送る挟圧ローラ４３，４４，４５が対をなして三箇所に設けられている。
【００２５】
主シール装置４１は、図示の例では、加熱用の熱板４１Ａと受板４２Ｂとを有し、電源から電力を受け両者間で重ね合せ部Ｆ２を所定圧で圧しながら加熱し、該重ね合せ部Ｆ２の側縁に一定幅の非シール部を残して連続して主シール部Ｓ１（図２にて細斜線霧状表示を施した帯状部分）を形成する。該主シール部Ｓ１に挟圧ローラ４４によりその面が整えられる。
【００２６】
次に、副シール部４２は、加熱ローラ４２Ａと受ローラ部４２Ｂとを有し、上記主シール部Ｓ１の領域で重ねて点状に副シール部Ｓ２を形成する。該副シール部Ｓ２は主シール部Ｓ１に比し単位シール面積当りのシール強度が大きい。上記加熱ローラ４２Ａは電源から電力を受けて抵抗加熱されるリング体に加熱突部４２Ｃが周囲の複数箇所（図２では四箇所）に設けられていて、この加熱ローラ４２Ａの回転に伴い加熱突部４２Ｃが上記受ローラ４２Ｂとの間で重ね合せ部Ｆ２を圧するときに上記点状の副シール部Ｓ２が形成される。なお、この副シール部Ｓ２も挟圧ローラ４５によりその面が整えられる。
【００２７】
上記主シール装置４１と副シール装置４２は共に、図示しない制御装置が接続されていて、加熱のための電力が独立して変更調整できるようになっている。
【００２８】
本実施形態装置において、主シールと副シールそれぞれのシール強度は、供給電力の調整によって変更できるが、シール面での接圧を調整することによっても可能である。これは、以下の他の実施形態でも同様である。
【００２９】
かかる本実施形態装置によると包装体は次の要領で作られる。
【００３０】
▲１▼先ず、帯状のフィルムＦは、図１においてガイドローラ２によりフォーミングプレート１へ案内されながら走行する。
【００３１】
▲２▼フィルムＦは、図２に示されるごとく、フォーミングプレート１により重ね合せ部Ｆ２が形成されて筒状となった後に縦シール装置３により溶着されて筒体Ｆ１となる。上記縦シール装置３では、主シール装置４１、副シール装置４２の順で重ね合せ部Ｆ２は溶着シールされる。既述したように、主シール装置４１で形成される主シール部Ｓ１は工程の上流から下流へと連続しており（このシ−ル部を「縦シール」ということがある。）、副シール装置４２で形成される副シール部Ｓ２は上記主シール部Ｓ１の領域内で定間隔をもって点状に形成される。そして、シール単位面積当りのシール強度は副シールＳ２の方が主シールＳ１よりも大きい。主副シ−ル部の長さが縦シール方向に夫々２５ｍｍ以上で、そのシール部の溶着幅が１ｍｍのとき溶着強度は後述の値となる。単位シール面積当りの溶着強度はここから換算する。主副シール部の長さ及びシール部の溶着幅に応じて、実測して換算する。そのシ−ル強度は主シールが１０〜８００ｇｆ／２５ｍｍ幅、副シールが５０〜２０００ｇｆ／２５ｍｍ幅であることが好ましく、また主シールが１０〜４００ｇｆ／２５ｍｍ幅、副シールが５０〜１０００ｇｆ／２５ｍｍ幅であることが更に好ましい。上記主シール及び副シールがそれぞれ１０，５０ｇｆ／２５ｍｍ以下だと内容物の内圧や充填後の取扱中にシールが剥れることがあり、又、主シール及び副シールがそれぞれ８００，２０００ｇｆ／２５ｍｍ以上であると開封が困難となったり、側縁の摘み部である非シール部を指で摘んで包装体を開封するときに、このシール部にてフィルムが切除されて包装体を開封できなくなるということがある。
【００３２】
▲３▼筒体Ｆ１には上流方向からノズル８が進入して配設されており、該ノズル８から筒体Ｆ１内に内容物（例えば粘稠物）が充填され充填物となる。充填物は充填位置よりも下流でダンパーベルト９によって、工程の上流から下流へと連続して偏平形状となると共にダンパーベルト９の上流側に生じる液溜りで脱気され、その後に、しごきローラ１４によって所定間隔位置に内容物の存在ないしごき部が横方向に形成される。
【００３３】
▲４▼しかる後、充填物は搬送ベルト１９によって開状態の上流側の金型１７内にもちこまれ、ここで金型１７が下流に移動しながら閉じられるために、所定外形形状に押圧成形される。金型１７が下流位置に到達すると該金型１７は開いて、成形された充填物は搬送ベルト１９により金型１７から取り出されて挟圧コンベア３２に移行する。なお、上記閉状態となって金型１７が下流に移動する際には、下流位置で開状態となっていたもう一方の金型１８が上流に向け早戻りして帰還する。
【００３４】
▲５▼かくして、挟圧コンベア３２によって搬送ベルトコンベア３３にもたらされた充填物は該搬送ベルトコンベア３３上にて、上記しごき部が横シールされると共に該横シール部で切断されて上記充填物は個々の製品としての包装体Ｐとなって搬出される。
【００３５】
本実施形態において、製品としてでき上がった包装体Ｐは、図３（Ａ），（Ｂ）に見られるごとく、合掌貼りの重ね合せ部分Ｆ２に上記縦シールが施され、そして両端部に横シールが施されたピロー型である。図３（Ａ）では上記合掌貼りとされた重ね合せ部Ｆ２は包装体Ｐの面に沿うように倒れた状態で、図３（Ｂ）では開封に備えて起立された状態でそれぞれ示されている。
【００３６】
包装体Ｐの重ね合せ部Ｆ２は、側縁に一定幅にわたり包装体Ｐの開封に用いる摘み部である非シ−ル部が残された状態で、上記側縁に沿って連続して帯状に延びる主シール部Ｓ１が形成され、さらに、この主シール部Ｓ１内に定間隔該主シール部Ｓ１と重ねて点状に形成された副シール部Ｓ２とが形成されている。そして、副シール部Ｓ２は、主シール部Ｓ１と比較して、単位シール面積当りのシール（溶着）強度が高い。
【００３７】
かくして、上記包装体Ｐは連続せる主シール部Ｓ１に加えてこれを補強するように施された副シール部Ｓ２とによって、シールされる。したがって、包装体Ｐが大きな重いものであっても、その自重によって、取扱い中に上記縦シール部分が剥離して内容物が露呈あるいは洩出することはない。
【００３８】
次に、内容物を取り出すときには、図３（Ｂ）において、重ね合せ部の側縁非シール部分を指で摘んで、一端側から他端側に向けて両側へ拡げるように引いて開封力を与える。この開封力によって主シール部Ｓ１は容易に開封される。副シール部Ｓ２に対しては、上記開封力は包装体Ｐの一端側の一つの点の副シール部Ｓ２に集中して作用しこれを開封した後に次の点へ順に作用するので、作業者にとって何ら負担とはならない。
【００３９】
図３に示された包装体Ｐの重ね合せ部は合掌貼りの例であるが、本発明はこれには限定されず、どのような形態のものにも適用できる。例えば、図４（Ａ）の通常の封筒貼り溶着、図４（Ｂ）の内側に引出し用の折り返し部分Ｆ３をもつ封筒貼り溶着、さらには図４（Ｃ）のような、合掌合せ部を包装体面に折り合わせてこれらを溶着する形態等、いずれにも適用される。勿論、その際、縦シール装置はそれらに適合する形態とする。
【００４０】
以上説明した実施形態では、縦シール装置は主シール装置と副シール装置とが別体に形成されていたが、両者を一体とすることも可能である。
【００４１】
図５において、縦シール装置５１は超音波溶着装置であり、ホーン５１とアンビル５２とを有しており、両者間で合掌貼りの形態のフィルムの重ね合せ部Ｆ２を溶着して縦シールを施す。このための装置は図６のごとく構成できる。図６において、ホーン５１を励振する発振アンプ５３は電源５４から電力の供給を受け、上記発振アンプ５３は制御装置５５により制御される。この制御装置５５は制御回路等を内包し制御状況を表示する制御パネル５６と、該制御パネル５６での制御条件の変更・調整を行うための二つの入力部Ｖ１，Ｖ２とを有している。一方の入力部Ｖ１は主シールのため、他方の入力部Ｖ２は副シールのためのものである。これらの入力部Ｖ１，Ｖ２では、設定者が発振アンプの超音波振動の振幅を時間的に変更するように設定できる。その結果、ホーン５１は、設定された主シールのための連続した一定レベルの振幅振動（バイアス振動）に、副シールのために間欠的に発せられる高レベルの振幅振動を合成する振幅振動を重ね合せ部Ｆ２に印加する。その結果、一つのホーン５１によって、図５のごとく、連続せる主シール部Ｓ１上に島状の副シール部Ｓ２が重ねて形成される。
【００４２】
前記振幅を時間的に変更する方法には、例えばリレー方式、超音波振幅変調方式などがある。また超音波溶着の他の実施態様として、ホーンの先端位置を機械的に僅かに移動または振動させて、前記ホーン先端位置とアンビル位置との間隔を時間的に変更してもよい。上記超音波振幅変調方式において副シールのための高レベル振幅振動は、時間的に振幅が曲線変化する若しくは時間的に振幅が所定間隔でパルス状変化する手段で印加できる。
【００４３】
図５の例は、重ね合せ部Ｆ２が合掌貼りの形態であったが、これは封筒貼りの形態でも可能である。図７において、ホーン５１は、フィルムの筒体Ｆ１を該筒体Ｆ１内で案内するリング状の５２Ａと協働する。そして、上記ホーン５１は、図５の場合と同様に、図６のごとくの制御装置５５に接続され制御される。
【００４４】
なお、本発明にあっては、フィルムの材料としては、低密度ポリエチレン、高密度ポリエチレン、エチレンαオレフィン共重合体である線状低密度ポリエチレン、エチレン（メタ）アクリル酸共重合体、エチレン（メタ）アクリル酸アルキレート共重合体、ポリプロピレンおよびこれらの樹脂組成物、ポリアミド、塩化ビニル樹脂、塩化ビニリデン樹脂を好ましく用いることができる。
【００４５】
【発明の効果】
本発明は、以上のように、包装体の溶着による縦シールを連続せる主シールと該主シールに沿って点在する副シールとによって形成し、副シールの単位シール面積当りの溶着強度を主シールにより強くすることとしたので、包装体の開封前の取扱中では十分なるシールが確保され、開封時には包装体の一端側から容易に開封でき、包装体の製造工程においてシール装置の調整幅が広くなりそして安定した品質保証を得られることの両面での改善がなされる。
【００４６】
又、上記包装体のための充填包装装置では、従来型の主シール装置に加えて、副シール装置を加えるだけなので、その構成も簡単であり、さらには、既存の装置の改良も簡単になされる。その際、主シール装置と副シール装置とを一体型とすれば、制御装置の回路変更だけでよく、機械的な変更を要せず改善はさらに簡単となる。

BACKGROUND OF THE INVENTION
The present invention relates to a so-called easy-open packaging body that can be easily opened and a filling packaging apparatus for producing the same.
[0002]
[Prior art]
This type of package is formed by forming a superposed portion by forming a film into a cylindrical shape, and welding in a direction (longitudinal direction) along the side edge of the superposed portion within the region of the superposed portion. A cylindrical body having a seal portion (hereinafter referred to as a “vertical seal portion”) is filled in the cylindrical body, and then in a direction perpendicular to the side edge at a predetermined interval along the side edge. It is obtained by forming the horizontal seal portion.
[0003]
The vertical seal portion is formed in various forms. For example, gluing, normal envelope attachment, envelope attachment having an inner folded portion, and the like. As an example, gazette sticking is disclosed in Japanese Patent Publication No. 6-62131. In this palm attachment, an overlapping portion is formed so that the side edges of the film overlap with each other on the inner side surfaces, and the film is continuously sealed along the side edges with a constant width except for the side edges. . When opening the package, the vertical seal portion is separated by picking and spreading the two films with fingers at the non-sealing portion which is the side edge picking portion. Thus, the contents can be taken out.
[0004]
[Problems to be solved by the invention]
In general, it is desirable that the package has a high sealing strength and does not open unintentionally before opening, and that it can be easily opened when opened. That is, contradictory conditions regarding the seal strength are required. This is desirable for any package as long as the sealed package is eventually opened. The above-mentioned known Japanese Patent Publication No. 6-62131 is no exception. In this known package, the vertical seal is continuously continuous in the vertical direction, so if the seal strength is increased, the sealability is improved, but it cannot be easily opened, and if the seal strength is decreased, it is easily It can be opened, but it may be opened carelessly during handling before opening.
[0005]
An object of the present invention is to provide a packaging body that can satisfy such conflicting requirements and can be easily opened and has a sealing strength, and a filling packaging apparatus therefor.
[0006]
[Means for Solving the Problems]
According to the present invention, with respect to the easy-open packaging body, the above-described object is to form a superposed portion by forming a film into a cylindrical shape, and in a direction along the side edge of the superposed portion within the superposed portion. A cylindrical body having a vertical seal portion formed by welding, and a horizontal seal portion is provided in a direction perpendicular to the side edge at a predetermined interval position in the direction in which the side edge extends after the contents are filled in the cylinder. In the formed packaging body, the vertical seal portion has a main seal portion formed continuously in parallel with the side edges, and a sub seal portion formed discontinuously along the main seal portion. The welding strength per seal area is achieved by the fact that the secondary seal part is larger than the main seal part.
[0007]
Since such a package is continuously sealed by the main seal portion, leakage of contents is prevented, and a certain degree of seal strength is secured. In the present invention, in addition to this, the secondary seal portion having high welding strength is formed discontinuously, whereby the overall seal strength becomes sufficient. Therefore, it does not open carelessly when not intended. At the time of opening, since it is opened from one end side in the sealing direction, the discontinuous sub-sealed portions are separated in an impact manner in order to remove the snaps one by one. This is not a significant burden on the operator. Since the main seal portion has a sealing strength that is relatively easy to separate, even if the main seal portion is separated at the same time in addition to the sub seal portion, it is within the range of force allowed for the operator.
[0008]
In the easy-open packaging body of the present invention, the sub seal portion may be formed in the region of the main seal portion so as to overlap with the main seal portion, or may be formed at a position close to the main seal portion. Either way, the same effect is obtained. Further, the sub seal portion can be welded in a dotted or linear manner at regular intervals in the vertical direction.
[0009]
According to the present invention, the overlapping portion is any one of gluing pasting welding, envelope pasting welding, envelope pasting having an inner folding portion, envelope pasting having an outer folding portion, and welding in which the palm joining portion is folded on the package surface. Even applicable. At that time, when the overlapping part is an envelope pasting having the inner or outer folded part and the secondary seal is formed close to the main seal, the secondary seal is within the range of the folded part. Preferably there is.
[0010]
Furthermore, according to the present invention, the above object relates to a filling and packaging apparatus for producing an easy-open packaging body, and forming a cylindrical shape by forming overlapping portions on both sides while guiding a running belt-like film. A plate device, a vertical sealing device for forming a cylinder by welding the film at the overlapping portion, a nozzle for filling the contents with the tip entering the inside of the cylinder, and after filling the contents In a filling and packaging apparatus comprising a horizontal sealing device that seals the cylindrical body at a predetermined interval position, the vertical sealing device is in the same direction as the main sealing device that continuously seals the film in the running direction. A secondary seal device that seals at a continuous position, and the secondary seal device is achieved by setting the welding strength per unit seal area to be larger than that of the main seal device.
[0011]
Either the main seal device or the sub seal device may be located upstream in the traveling direction of the film.
[0012]
It is desirable that at least one of the main seal device and the sub seal device is connected to a control device that can vary the welding strength at the time of sealing. Thereby, the relative relationship of the seal strength between the main seal portion and the sub seal portion can easily correspond to the packaging form or the required sealability and the required easy-opening property.
[0013]
The vertical sealing device of the present invention can be applied to any of known ultrasonic sealing devices, resistance heating devices, high-frequency dielectric heating sealing devices, hot air sealing devices, and molten resin particle sealing devices as welding forms themselves.
[0014]
In addition, Japanese Utility Model Publication No. 46-36232 discloses a structure in which a cut hole or a cut line is formed along the vertical seal portion. However, this does not have a function of reinforcing the seal portion, and is a subsidiary of the present invention. It is completely different from the seal.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0016]
In FIG. 1, reference numeral 1 denotes a forming plate, and after the belt-like film F fed at a constant speed by a guide roller 2 such as 2A, 2B, 2C is wound into a cylindrical shape by the forming plate 1, While the overlapping portion F2 is formed in the form of a palm-fitting, it is welded by the vertical sealing device 3 to form a film cylinder F1. As often seen in FIG. 2, the vertical sealing device 3 will be described in detail later. Although illustrated as a sealing device by ultrasonic welding, the vertical sealing device is not limited to ultrasonic welding, but by resistance heating welding, high-frequency dielectric heating welding, hot air welding, welding by spraying molten resin particles (bead seal), or the like. Other known sealing devices may be used. The vertical sealing device 3 will be described in detail later.
[0017]
As shown in FIG. 1, three types of 4A, 4B, and 4C ring-shaped guides 4 for setting the cross-sectional shape of the cylindrical body F1 to a predetermined shape are disposed just below the forming plate 1, and the cylindrical F1 Guiding the driving. The guide 4 in the upstream position 4A has a circular shape and the downstream position 4C has an oval shape extending in a direction perpendicular to the paper surface, and passes through the guide 4C in the downstream position that guides the cylinder F1 flat. Thus, the cylindrical body F1 is drawn out in a flat shape.
[0018]
Two pairs of feed rollers 5 composed of counter rollers 5A and 5B that are in pressure contact with each other are arranged on the downstream side of the guide 4 on both sides in the direction perpendicular to the paper surface. Sending out in the downstream direction. On the other hand, between the two pairs of feed rollers 5 and 5, a nozzle 8 for continuously filling the contents accommodated in the hopper 6 into the cylinder F1 by the filling pump 7 extends.

The secondary seal portion S2 has a higher seal strength per unit seal area than the main seal portion S1. The heating roller 42A is provided with heating projections 42C at a plurality of surrounding locations (four locations in FIG. 2) on a ring body that is resistance-heated by receiving electric power from a power source. When the portion 42C presses the overlapping portion F2 with the receiving roller 42B, the dotted sub-seal portion S2 is formed. Note that the surface of the sub seal portion S2 is also trimmed by the pinching roller 45.
[0027]
Both the main seal device 41 and the sub seal device 42 are connected to a control device (not shown) so that the power for heating can be changed and adjusted independently.
[0028]
In the apparatus of the present embodiment, the seal strength of each of the main seal and the sub seal can be changed by adjusting the supplied power, but can also be adjusted by adjusting the contact pressure on the seal surface. The same applies to other embodiments described below.
[0029]
According to the apparatus of this embodiment, the package is made in the following manner.
[0030]
(1) First, the belt-like film F travels while being guided to the forming plate 1 by the guide roller 2 in FIG.
[0031]
{Circle around (2)} As shown in FIG. 2, the film F is welded by the vertical sealing device 3 after the overlapping portion F <b> 2 is formed by the forming plate 1 to form a tubular body F <b> 1. In the vertical sealing device 3, the overlapping portion F <b> 2 is welded and sealed in the order of the main sealing device 41 and the auxiliary sealing device 42. As described above, the main seal portion S1 formed by the main seal device 41 is continuous from the upstream to the downstream of the process (this seal portion is sometimes referred to as “vertical seal”), and the secondary seal. The sub seal portion S2 formed by the device 42 is formed in a dot shape at regular intervals within the region of the main seal portion S1. In addition, the seal strength per unit area of the seal is larger in the sub seal S2 than in the main seal S1. When the length of the main / sub seal part is 25 mm or more in the longitudinal seal direction and the weld width of the seal part is 1 mm, the weld strength is a value described later. The welding strength per unit seal area is converted from here. Measured and converted according to the length of the main / sub seal part and the welding width of the seal part. The seal strength is preferably 10 to 800 gf / 25 mm width for the main seal and 50 to 2000 gf / 25 mm width for the sub seal, and 10 to 400 gf / 25 mm width for the main seal and 50 to 1000 gf / 25 mm for the sub seal. More preferably, it is a width. If the main seal and sub-seal are 10,50 gf / 25 mm or less, the internal pressure of the contents or the seal may peel off during handling after filling, and the main seal and sub-seal are 800, 2000 gf / 25 mm or more, respectively. If it is, it will be difficult to open, or when the package is opened by picking the non-seal part which is the side edge knob part with the finger, the film will be cut off at this seal part and the package can not be opened Sometimes.
[0032]
{Circle around (3)} The nozzle 8 is disposed in the cylinder body F1 from the upstream direction, and the contents (for example, viscous material) are filled into the cylinder body F1 from the nozzle 8 to become a filling material. The filling material is continuously flattened from the upstream to the downstream of the process by the damper belt 9 downstream of the filling position and degassed by the liquid pool generated on the upstream side of the damper belt 9, and then the squeezing roller 14 As a result, the presence of the contents or the iron portion is formed in the lateral direction at predetermined intervals.
[0033]
(4) After that, the filling material is brought into the upstream mold 17 in the opened state by the conveyor belt 19, and the mold 17 is closed while moving downstream. The When the mold 17 reaches the downstream position, the mold 17 is opened, and the formed filling is taken out from the mold 17 by the conveyor belt 19 and transferred to the pressure conveyor 32. When the mold 17 moves downstream in the closed state, the other mold 18 that has been opened at the downstream position quickly returns upstream and returns.
[0034]
(5) In this way, the filling material brought to the conveyor belt conveyor 33 by the pinching conveyor 32 is laterally sealed on the conveyor belt conveyor 33 and cut at the lateral seal part to cut the filling. A thing is carried out as the package P as an individual product.
[0035]
In this embodiment, as shown in FIGS. 3 (A) and 3 (B), the package P completed as a product is provided with the vertical seal on the overlapped portion F2 with the palms and horizontal seals at both ends. It is a pillow type. In FIG. 3 (A), the overlapped portion F2 that is affixed to the palm is shown in a state where it falls down along the surface of the package P, and in FIG. 3 (B), it is shown in a standing state in preparation for opening. Yes.
[0036]
The overlapping portion F2 of the package P is continuously stripped along the side edge in a state where a non-seal portion, which is a knob used for opening the package P, is left on the side edge over a certain width. An extended main seal portion S1 is formed, and further, a sub seal portion S2 is formed in the main seal portion S1 so as to overlap with the main seal portion S1 at regular intervals and formed in a dot shape. The sub seal portion S2 has a higher seal (welding) strength per unit seal area than the main seal portion S1.
[0037]
Thus, the package P is sealed by the main seal portion S1 that is continuous and the sub seal portion S2 that is applied to reinforce the package. Therefore, even if the package P is large and heavy, the vertical seal portion does not peel off during handling due to its own weight, and the contents are not exposed or leaked.
[0038]
Next, when taking out the contents, in FIG. 3 (B), pick the side edge non-sealed part of the overlapped part with your finger and pull it so that it spreads from one end side to the other side. give. The main seal portion S1 is easily opened by this opening force. For the secondary seal portion S2, the opening force acts on the secondary seal portion S2 at one point on the one end side of the package P in a concentrated manner. It will not be a burden for them.
[0039]
Although the overlapping part of the package P shown in FIG. 3 is an example of joint-pasting, the present invention is not limited to this and can be applied to any form. For example, the usual envelope bonding welding shown in FIG. 4A, the envelope bonding welding having the folded-back portion F3 inside the drawing shown in FIG. 4B, and the jointing portion as shown in FIG. The present invention can be applied to any form such as folding the body surface and welding them. Of course, in that case, the vertical sealing device is configured to be adapted to them.
[0040]
In the embodiment described above, the main seal device and the sub seal device are formed as separate bodies in the vertical seal device, but they can also be integrated.
[0041]
In FIG. 5, a vertical sealing device 51 is an ultrasonic welding device, which has a horn 51 and an anvil 52, and welds a film overlap portion F2 in the form of a palm-pasted film between them to perform vertical sealing. .

The control device 55 includes a control panel 56 that includes a control circuit and the like and displays a control status, and two inputs V1 and V2 for changing / adjusting control conditions on the control panel 56. . One input part V1 is for the main seal and the other input part V2 is for the secondary seal. In these input parts V1 and V2, the setter can set the amplitude of the ultrasonic vibration of the oscillation amplifier to change with time. As a result, the horn 51 superimposes an amplitude vibration that synthesizes a high-level amplitude vibration intermittently generated for the secondary seal on the set constant amplitude vibration (bias vibration) for the main seal. Apply to the mating portion F2. As a result, as shown in FIG. 5, the island-like sub-seal portion S2 is formed on the main seal portion S1 that is continuous by the single horn 51.
[0042]
Examples of the method for changing the amplitude over time include a relay method and an ultrasonic amplitude modulation method. As another embodiment of ultrasonic welding, the tip position of the horn may be slightly moved or vibrated mechanically to change the interval between the horn tip position and the anvil position in terms of time. In the ultrasonic amplitude modulation method, the high-level amplitude vibration for the sub-seal can be applied by means in which the amplitude changes in a curve with time, or the amplitude changes in pulses at a predetermined interval in time.
[0043]
In the example of FIG. 5, the overlapping portion F <b> 2 is in the form of palm-pasting, but this is also possible in the form of envelope-pasting. In FIG. 7, a horn 51 cooperates with a ring-shaped 52A for guiding a film cylinder F1 within the cylinder F1. And the said horn 51 is connected to the control apparatus 55 like FIG. 6, and is controlled similarly to the case of FIG.
[0044]
