Abstract

Le problème décrit par la présente invention consiste à faciliter la déchirure d'une perforation pour former une ouverture d'extraction. La solution selon la présente invention porte sur : un groupe de serviettes (3) dans lequel des serviettes hygiéniques (2) sont empilées ; et un emballage (4) qui est formé d'un film souple et utilisé pour emballer le groupe de serviettes. La partie de surface supérieure de l'emballage (4) présente une section de formation d'ouverture d'extraction (10) dans laquelle une ouverture d'extraction longue et mince (20) est formée et présente un élément mince et long (13) qui est disposé entre la surface supérieure de l'emballage (4) et le groupe de serviettes (3) et s'étend d'une extrémité à l'autre extrémité de la section de formation d'ouverture d'extraction (10). L'emballage (4) présente une première partie fixe (41) et une seconde partie fixe (42) qui sont respectivement fixées à des parties de l'élément mince et long (13) qui sont situées au niveau de chaque extrémité de la section de formation d'ouverture d'extraction (10), et présente une perforation (12) s'étendant entre la première partie fixe (41) et la seconde partie fixe (42) dans une direction raccordant les parties fixes. L'emballage (4) présente une partie de préhension (11) incluant la première partie fixe (41) et disposée sur le côté de première partie fixe (41) de la perforation (12) et présente une partie de préhension (11) incluant la seconde partie fixe (42) et disposée sur le côté de seconde partie fixe (42) de la perforation, les parties de préhension (11) étant configurées pour pouvoir être séparées de leur environnement.
