Abstract
を備える。チャック壁(6)に形成された凹状アーチは、約0.38〜2.03mm(約0.015〜0.080インチ)の曲率半径を有する。
Description
同図において、これら3つの端部の上側チャック壁の差異は容易に理解される。より詳細には、標準202缶端部と異なり、且つ、本発明の種々の実施形態に記載する缶端部と同様に、特許文献1に記載の端部におけるチャック壁上端は40〜60度の非常に大きな角度をもって内方を指向し、それによって上側チャック壁と缶本体ネックとの間に大幅な離間をもたらしている。前述の通り、このような差異は、缶端部2を缶本体ネック26に対してダブルシーミングする際に問題を生じる。このダブルシーミングについては、高い信頼性を有すると共に長期にわたって用いられてきた標準202缶端部にて得られるダブルシーミングとは違って、特許文献1に開示される飲料缶端部のシーミングにおいては金属のより多くの移動が必要になる。図2Aに示すように、本発明は、従来の202缶端部に類似する幾何学的構造を伴う上側チャック壁角度を用いている。このことによって、機器の変更の必要性と、仮想鉛直面から測定して大きな内方指向角度を有する上側チャック壁8を用いる従来技術の飲料缶に関連する潜在的なダブルシーミングの問題とが解消される。
