Title
(EN) SHEETLIKE COMPOSITE, ESPECIALLY FOR PRODUCTION OF DIMENSIONALLY STABLE FOOD AND DRINK PRODUCT CONTAINERS, HAVING A ROOF AREA FORMED BY A MULTITUDE OF GROOVE LINES HAVING PARTLY CONVEX CURVATURE
(FR) COMPOSITE EN FORME DE FEUILLE, EN PARTICULIER POUR LA PRODUCTION DE RÉCIPIENTS DE PRODUITS ALIMENTAIRES ET DE BOISSONS DE DIMENSIONS STABLES, AYANT UNE ZONE DE TOIT FORMÉE D'UNE MULTITUDE DE LIGNES DE RAINURE AYANT UNE COURBURE PARTIELLEMENT CONVEXE
Abstract
(EN)
The present invention relates to a sheetlike composite comprising, as mutually superposed layers, a) a carrier layer, b) a barrier layer, and c) an inner polymer layer, wherein the sheetlike composite has a multitude of groove lines arranged and configured such that, by folding the sheetlike composite along the groove lines and joining seam areas of the sheetlike composite thereby obtaining seams, a closed container is obtainable, wherein the closed container has a roof area, wherein a first portion of the groove lines of the multitude of groove lines at least partly forms a circumference of a first part-area of the roof area, wherein the groove lines of the first portion, relative to the first part-area of the roof area, have at least partly convex curvature, wherein the first part-area of the roof area has a first length in a longitudinal direction and has a second length in a circumferential direction at right angles to the longitudinal direction, wherein a ratio of the first length to the second length is in a range from 0.2 to 2.0. The invention further relates to methods of producing a sheetlike composite, a container precursor and a closed container, and to the aforementioned method products; to a further container precursor; to a further closed container; and to a use of the sheetlike composite.
(FR)
La présente invention concerne un composite en forme de feuille comprenant, sous forme de couches mutuellement superposées, a) une couche de support, b) une couche barrière, et c) une couche de polymère interne, le composite en forme de feuille ayant une multitude de lignes de rainure disposées et configurées de telle sorte que, en pliant le composite en forme de feuille suivant les lignes de rainure et en reliant les zones de jonction du composite en forme de feuille, obtenant ainsi des jonctions, on peut obtenir un récipient fermé, le récipient fermé ayant une zone de toit, une première partie des lignes de rainure de la pluralité de lignes de rainure formant au moins partiellement une circonférence d'une première zone partielle de la zone de toit, les lignes de rainure de la première partie, par rapport à la première zone partielle de la zone de toit, présentant une courbure au moins partiellement convexe, la première zone partielle de la zone de toit ayant une première longueur dans une direction longitudinale et ayant une seconde longueur dans une direction circonférentielle perpendiculaire à la direction longitudinale, un rapport de la première longueur à la seconde longueur étant dans une plage comprise entre 0,2 et 2,0. L'invention concerne en outre: des procédés de production d'un composite en forme de feuille, d'un précurseur de récipient et d'un récipient fermé; les produits du procédé susmentionnés; un autre précurseur de récipient; un autre récipient fermé; et une utilisation du composite en forme de feuille.
