A flexible cover (1) for a food container (4) comprising a flexible film (2) and an elastic thread (3) is presented. The elastic thread (3) is attached to the peripheral edge (8) of the flexible film (2) by a channel (5) formed of the flexible film (2) around the elastic thread (3). The channel (5) exerts a circumferential, compressive force on the elastic thread (3), whereby the elastic tread (3) is fixed to the flexible film (2) by friction between the flexible film (2) and the elastic thread (3), and the elastic thread (3) forms a loop around the peripheral edge (8) of the flexible film (2), the loop having two ends (6, 7) overlapping and abutting in a longitudinal direction of the elastic thread (3). A method for manufacturing a flexible cover (1) is also presented.
L'invention porte sur un couvercle souple (1) pour un récipient pour aliment (4), comprenant un film souple (2) et un fil élastique (3). Le fil élastique (3) est fixé au bord périphérique (8) du film souple (2) par un canal (5) formé à l'aide du film souple (2) autour du fil élastique (3). Le canal (5) exerce une force de compression circonférentielle sur le fil élastique (3), grâce à quoi le fil élastique (3) est fixé au film souple (2) par frottement entre le film souple (2) et le fil élastique (3), et le fil élastique (3) forme une boucle autour du bord périphérique (8) du film souple (2), la boucle comportant deux extrémités (6, 7) se chevauchant et en butée dans une direction longitudinale du fil élastique (3). L'invention porte également sur un procédé pour fabriquer un couvercle souple (1).
