Title
(EN) EASY-OPEN END AND LAMINATED STEEL SHEET
(FR) PARTIE D'EXTREMITE FACILE A OUVRIR ET FEUILLE DE TOLE STRATIFIEE
(JA) イージーオープンエンドおよびラミネート鋼板
Abstract
(EN) An easy-open end which comprises a steel sheet and formed on at least one side thereof an about 10-30 μm-thick coating film of a polyester resin having a 50% crystallization time of about 5 minutes or shorter and a coefficient of planar orientation of about 0.04 or lower and which has a groove for cutting which has a cross section having a radius of curvature of about 0.1 to 1 mm; and a laminated steel sheet for use in the easy-open end. This easy-open end can combine suitability for opening and no need of repair even when the residual score thickness is small.
(FR) Cette invention se rapporte à une partie d'extrémité facile à ouvrir, qui comprend une feuille de tôle, sur au moins l'un des côtés de laquelle est formé un film de revêtement d'environ 10 à 30 $g(m)m d'épaisseur en résine de polyester ayant une durée de cristallisation à 50 % d'environ 5 minutes au maximum et un coefficient d'orientation planaire d'environ 0,04 au maximum et qui comporte une rainure de découpage présentant un rayon de courbure d'environ 0,1 à 1 mm ; ainsi qu'à une feuille de tôle stratifiée destinée à être utilisée dans cette partie d'extrémité facile à ouvrir. Cette partie d'extrémité facile à ouvrir est pratique à ouvrir et en même temps ne nécessite pas de réparation, même lorsque l'épaisseur d'incision résiduelle est faible.
(JA)  本発明は、鋼板の少なくとも片面上に、1/2結晶化時間が約5分以下で面配向係数が約0.04以下のポリエステル樹脂の皮膜を厚さ約10~約30μmで有し、かつ断面形状が曲率で約0.1~約1mmである切断用の溝を設けたイージーオープンエンドおよびそれに用いるラミネート鋼板である。これにより、イージーオープンエンドは、スコア残厚を薄くても開口性と無補修化を両立できる。
