図1は、本発明のガス置換装置の実施形態に係るアンダーカバーガッシング装置のノズル体の平面断面図であり、図10に示すガスターレット1の円弧状凹部(ポケット)3に面するように設けられる。ガスターレット1のガスターレット本体10の上面にノズル体11が固定され、該ノズル体の内部に各円弧状凹部3に通じる置換ガス流路12が形成されている。
缶形状についてはネック部の有無や種々のネック形状があり、また、蓋形状についても種々の高さがあるので、これらに対応するためは具体的な数値として、缶開口部を基準として胴部方向は、缶開口端から3mm以上の範囲、より好ましくは5mm以上の範囲がよく、缶上部方向は、缶開口端から3mm以上の範囲、より好ましくは8mm以上の範囲がよい。それにより、従来のアンダーカバーガッシングのノズル体の流路高さは約8mmであるが、本実施形態ではガス流路の高さhを約13mmの高さに高くしてある。
開口角度を120°に広げた影響は、衝突する噴流の角度そのものを大きくすることにつながる。図8は、2方向から衝突する噴流において、(a)衝突の角度が90°の場合と(b)衝突の角度が120°の場合で衝突後の広がりを数値解析した結果を示している。図8(b)から衝突角度が120°の方が衝突後に広がる領域が広いことが分かる。衝突する噴流の角度を大きくすることで、衝突後の置換ガスが広がる領域が、より広くなることで置換効率が上がる効果があると考えられる。

(3)測定法
残存エア量:ヘッドスペースの初期設定をエアーとして、置換後のヘッドスペースのガスを採集し、酸素濃度を測定器にて残存酸素量を算出した。
液こぼれ量:シーマーを通過する前後の重量変化を測定して求めた。
比較例1として、ガス置換装置を図11に示す構造のノズル体においてノズル高さを8mmにしたものを採用した。その他のガス置換条件は実施例と同様である。
比較例2:
比較例2として、ガス置換装置を特許文献1に記載のように置換ガス流路にバッファを有し、噴射口が放射状に配置されている構造のノズルを採用した。その他のガス置換条件は実施例と同様である。
以上の比較例1、2において、置換ガス流量を600、800、1000Nl/minと変化させた場合のヘッドスペースの残存酸素量及び液こぼれ量を測定した。以上の実験を実施例及び比較例とも各6缶づつ行なった。各噴射流量ごとのそれぞれの残存酸素量の測定結果の平均値を実施例と共に図5に示す。図5においてa線図が実施例、b線図が比較例1、c線図が比較例2を表している。また、図6に液こぼれ量を表している。なお、図6において棒グラフが表示されて800Nl/minにおける比較例2では液こぼれが起きなかったことを意味している。
(1)残存酸素量、即ちガス置換率に関して、実施例の場合は、流量が600Nl/minから、800、1000と増えると、ヘッドスペースの残存酸素量は、約0.076mlから0.027mlまで半減した。比較例2の場合は流量が600Nl/minの場合、残存酸素量が共に約0.255mlあり、置換率が著しく悪い。流量を800、1000Nl/minと増やすことによって、残存酸素量は減り、置換率は向上しているが、800Nl/min以上では残存酸素量は約0.096からあまり下がらなかった上、実施例と比べて残存酸素量が3倍以上多く置換率が低い。
(2)一方、液こぼれ量に関して、実施例1の場合は、置換ガス流量が800Nl/minの場合は、液こぼれ量がほとんど無かった。また、1000Nl/minの時は液こぼれ量が1mlでありごく少量であった。
比較例1は、実施例に比べ残存酸素量は6割程度であるが液こぼれが1000Nl/minでは、実施例の5倍以上であった。
(3)以上の(1)(2)のことから、比較例2に示す従来技術では置換ガス流量が600Nl/minでは置換率が極端に悪く、実用的なガス置換率を得るには少なくとも800Nl/min以上を必要とするのに対し、実施例1では600Nl/minで比較例2の800Nl/minと比べて大幅に残存酸素量を減らすことができ、この量で実用的なガス置換が十分可能である。即ち、実施例によれば、従来のガス置換装置に比べて置換ガス使用量を30%以上節約できることを意味している。しかも、置換ガス流量が600Nl/minでは液こぼれ量もゼロであることが分かる。一方、比較例1はガス置換率については、実施例とほぼ同等以上の結果が得られているが、液こぼれ量が実施例1と比べて特段に多く、液こぼれを低減させる課題は達成できなかった。

吹出し口の形状:放射型櫛歯型ノズル
吹き出し角度(置換ガス噴射角度):120゜
吹出し口(ガス流路)の高さ:h=12mm
(2)ガス置換条件
全て、実施例1と同じ
その結果を表1に示す。
実施例2のノズル体と同様な放射型櫛歯型ノズル形状において、吹出し角度を100゜にし、且つ吹出し口の高さを7mmとしたノズル体を使用して実施例2と同様なガス置換条件で、置換ガス噴射流量900ccでアンダーカバーガッシングを行った場合の液こぼれ量及び残存酸素量を数値解析により求めた。その結果を実施例2とともに表1に示す。
