Abstract

L'invention porte sur des procédés sur un dispositif s'adaptant à un couvercle (36) de réceptacle comprenant une structure (32) de préhension fixée à une extrémité d'une bande d'ouverture (30) et placée dans un rebord extérieur (34) du couvercle. La structure (32) de préhension comporte une partie (37) configurée de façon à accueillir un élément de manipulation tel qu'au moins un doigt de la main de l'utilisateur, ce qui permet à l'utilisateur de commencer facilement à détacher la bande d'ouverture (30) du couvercle (36). La partie (37) de la structure de préhension est configurée de sorte que l'utilisateur n'ait plus besoin de saisir la bande d'ouverture (30) entre des doigts opposés.
