Abstract

La présente invention concerne un sac d'emballage, qui présente un bec verseur de contenu, qui fait saillie vers le haut. Le sac d'emballage permet que des résidus, comme du liquide ou de la poudre, présents à l'ouverture du bec verseur, ne salissent pas le bout des doigts car il est conçu de sorte que l'état replié du bec verseur de contenu puisse être maintenu, sans insérer le bec verseur de contenu, dont la pointe a été coupée pour être ouverte, dans une fente formée par découpe dans le sac d'emballage lui-même. Pour ce sac d'emballage, le bec verseur (10) de contenu est prévu de manière à pouvoir être fermé par pliage du sac, au niveau d'une section (14) de pliage prévue, qui s'étend sur le bec verseur (10) de contenu et une feuille (13) de scellement mince, dans le sens de la largeur du sac. La feuille (13) de scellement mince est dotée d'un moyen (16) de maintien de pliage, afin de maintenir le sac plié au niveau de la section (14) de pliage prévue.
