Abstract
Description
例えば、レンガ型形状の容器は、紙層の表裏面に熱可塑性樹脂層を有する包材に、容器用罫線を施し、包材の端部にエッジプロテクトテープを貼り、この包材を筒状に成形して当該包材端部同士を重ねて貼ることで、筒状形状の包材とする。そして、この筒状の包材の下端部を横断方向に接合して下端部をシール(封止)し、その後、筒状の包材の中に内容物を充填した状態で容器の口となる位置(上端部側)を横断方向に液中シールして仕切った後、立体形状に成形することで最終形態の容器形状とする。
すなわち、超音波シール装置によるシールは、容器のシール位置を、対向するホーンの先端面とアンビルの先端面とで押圧しホーンを超音波振動させることで、包材界面(重なり合うシート体同士の接触面位置)で発生する熱により包材表面に存在する熱可塑性樹脂を溶融させてシールする。特に、液体容器のシール状態は重要であり、上記のシールには内容物の保護、運搬・落下衝撃に耐えうる強度が必要とされる。
本発明は、上記のような点に着目してなされたもので、一対のホーンを使用した超音波シール技術において、アンビルの形状を工夫することで、シール部のシール性を向上させることを目的としている。
上記溶着面部は、上記ホーン側に突出し上記一対のホーンに形成された各振動付与面とそれぞれ対向し当該振動付与面の延在方向に沿って配設された左右の溶着面を有し、上記左右の溶着面は、それぞれ上記延在方向に沿った単位長さ当たりの面積が、上記一対のホーンの振動付与面の隣接側であるシール中央側から離れるほど、連続的若しくは段階的に大きくなるように設定されていることを特徴とする。
超音波シール装置1は、模式図である図1に示すように、超音波発振器9と、超音波振動子であるコンバータ2と、一対のホーン3(図1では1つのホーン3のみ図示)と、アンビル4とを有する。符号5は、アンビル4を支持するジョーを示す。符号6は、一対のホーン3をともに保護するホーンカバーを示す。
一対のホーン3は、図2に示すように、所定間隙(例えば1mmの間隙)を開けてシール方向に沿って並ぶように配列した状態で、1つのコンバータ2に支持されている。それぞれ個別のコンバータに支持する構成でも良い。このとき、一対のホーン3は、それぞれ縦方向の振幅が0(ゼロ)になるノーダルポイントの位置でOリング40を介して支持される。
すなわち、当接面4Aには、各振動付与面3aに向けてそれぞれ突出する2条の溶着面部10が形成されている。その各溶着面部10はそれぞれ、重ね合わされたシート体を挟んで、振動付与面3aと対向する。
また、帯状の溶着面部10の側方には、複数のブロック体11の列を有する。その複数のブロック体11の列は、溶着面部10の延在方向と同方向に沿って並び、隣り合うブロック体11が互いに非接触の状態となっている。
各複数のブロック体11は、図4に示すように、溶着面部10の延在方向に沿って配列するように設定されている。
ここで、少なくともシールするときには、筒状包材31は、図6(b)のように、扁平に潰された形状となっていて、図6(b)における紙面上下方向から、ホーン3とアンビル4で押圧することで、シール位置では、シート体を構成する包材30A、30Bが2層重なり合った積層体の状態となる。但し、上記の重なり部分Rでは、エッジプロテクションテープ32を含めると、シート体が4層重なり合った状態となっている。
その凹部10bがシール中央部分となる。そして、2条の溶着面部10はそれぞれ、シール中央側である凹部10bから、左右に延在するように配設した左右の溶着面10aを有する。左右の溶着面10aは、それぞれ上記延在方向に沿った単位長さ当たりの面積が、凹部10b側(2つの振動付与面3aの隣接側であるシール中央側)から離れるほど、連続的若しくは段階的に大きくなるように設定されている。
本実施形態では、図4では、左右の溶着面10aのシール面形状はそれぞれ、上記シール中央側から離れるにつれて連続して大きくなる台形形状となっている場合を例示している。図7に示すように、階段状に幅が広くなるようになっていても良いし、幅方向両側のプロフィールも直線状に限定されず、幅が連続的に広くなる曲線状のプロフィールであっても良い。
間隙が0.1mm未満では、シート体間に、空気が抜けるだけの隙間が形成されがたくなり、一方間隙が2mmを超えると、溶融した樹脂が外方に移動するおそれがあるためである。
また、2条の溶着面部10の間には、図1及び図4のように、断裁刃7が進退するナイフスリット15を構成する溝が配置されている。断裁刃7は、ホーン3側に向けて進退可能に設けられ、2条のシール位置の間を切断して先行と後続の紙容器を分離するために使用される。
図1は、先に容器下端部が封止され、内部に液体を充填されたレンガ型液体用紙容器の口(上端部)をシールすると同時に次の容器の下端部をシールする前の状態を示している。
この図1の状態から、一対のホーン3の振動付与面3aとアンビル4の当接面4Aとで筒状包材31を両側から所定の荷重で挟み込んで、筒状包材31を潰してシート体を積層した積層体の状態とし、ホーン3の振動付与面3aを超音波振動させることで、内装用樹脂層30eを溶融して紙面直交方向に2条のシール位置をシールする。
なお、シールが完了したら、断裁刃7を突出させて2条のシール位置の間を分断する。これによって現在の容器の封止が完了すると共に、上側に位置する次の容器の下端部がシールされる。
このような状態で、ホーン3の振動付与面3aを超音波振動させると、振動付与面3aと溶着面部10の間に位置する熱可塑性樹脂が溶融することで、振動付与面3aと溶着面部10の間に位置するシール位置で積層した筒状包材31がシール(封止)される。
この押し出された熱可塑性樹脂は、上記帯状の空隙部Sに流れ込むが、複数のブロック体11の列によってそれ以上外側に移動することが抑制される。すなわち、押し出された熱可塑性樹脂の移動は複数のブロック体11の列によって堰き止められる。
このように一列に並ぶ複数のブロック体11によって、はみ出た熱可塑性樹脂による樹脂塊の厚さと幅を制御可能となることから、過剰に熱可塑性樹脂が溶融された場合であっても、不定形な剥がれ易い溶融樹脂塊の形成を抑止することが出来る。
