(EN) SEALING DISC FOR PACKAGING CONTAINER WITH CONTROLLED INTERNAL PRESSURE AND METHODS FOR PRODUCING AND FILLING SUCH CONTAINER
(FR) DISQUE D'ÉTANCHÉITÉ POUR RÉCIPIENT D'EMBALLAGE À PRESSION INTÉRIEURE CONTRÔLÉE ET PROCÉDÉS DE FABRICATION ET DE REMPLISSAGE D'UN TEL RÉCIPIENT
Abstract
(EN)
The present disclosure relates to a paperboard sealing disc (10) for use in a paperboard packaging container (1 ) for bulk solids. The packaging container (1) comprises a container body (2) with an upper end (4) with an upper body opening (5') and a bottom end (6) with a bottom body opening (5"), a container wall (3) extending between the upper end (4) and the bottom end (6) in a longitudinal direction (L). The container wall (3) has an inner surface (7) facing towards an inner compartment (9) in the packaging container (1 ) and an outer surface (8) facing away from the inner compartment (9). The sealing disc (10) is intended for sealing the upper body opening (5') or the bottom body opening (5"). The sealing disc (10) comprises a sealing disc border (11) surrounding a sealing disc base portion (12), wherein the border (11) is delimited from the disc base portion (12) by a sealing disc inner folding edge (31). The sealing disc border (11) is intended to be flexed at the inner folding edge (31) to project out of a main plane of the sealing disc (10) and to be aligned with and sealed to the inner surface (7) of the container wall (3). The sealing disc (10) comprises one or more distance element(s) (14) arranged in the sealing disc border (11) and facing the inner surface (7) of the container wall (3), the distance element(s) (14) having a height (H), as measured from the surface of the sealing disc border (11).
(FR)
La présente invention concerne un disque d'étanchéité en carton (10) destiné à être utilisé dans un récipient d'emballage en carton (1) pour des matières solides en vrac. Le récipient d'emballage (1) comprend un corps de récipient (2) muni d'une extrémité supérieure (4) avec une ouverture de haut de corps (5'), et une extrémité inférieure (6) avec une ouverture de bas de corps (5"), une paroi de récipient (3) qui s'étend entre l'extrémité supérieure (4) et l'extrémité inférieure (6) dans une direction longitudinale (L). La paroi de récipient (3) comprend une surface intérieure (7) faisant face à un compartiment intérieur (9) dans le récipient d'emballage (1), et une surface extérieure (8) faisant face à l'opposé du compartiment intérieur (9). Le disque d'étanchéité (10) est destiné à rendre étanche l'ouverture de haut de corps (5') ou l'ouverture de bas de corps (5"). Le disque d'étanchéité (10) comprend une bordure de disque d'étanchéité (11) qui entoure une portion de base de disque d'étanchéité (12). La bordure (11) est délimitée de la portion de base de disque (12) par un bord de pliage intérieur de disque d'étanchéité (31). La bordure de disque d'étanchéité (11) est destinée à être fléchie au niveau du bord de pliage intérieur (31) pour faire saillie depuis un plan principal du disque d'étanchéité (10) et de façon à être alignée avec la surface intérieure (7) de la paroi de récipient (3) et à être scellée à celle-ci. Le disque d'étanchéité (10) comprend un ou plusieurs éléments d'écartement (14) disposés dans la bordure du disque d'étanchéité (11) et faisant face à la surface intérieure (7) de la paroi de récipient (3). Le ou les éléments d'écartement (14) ont une hauteur (H), mesurée à partir de la surface de la bordure de disque d'étanchéité (11).
