Abstract

L'invention concerne un système d'hydratation personnel comprenant une poche réservoir préremplie (10). La poche peut être remplie d'un liquide de boisson par un fournisseur, chauffée et scellée de manière aseptique. La poche (10) peut également être remplie à froid d'un liquide de boisson et de conservateurs puis scellée. La poche est de préférence conçue en tant qu'article à usage unique jetable. Afin de maintenir les contenus de la poche (10) frais et afin de faciliter la distribution du liquide à partir du réservoir par l'intermédiaire d'un tube pour boire (20), la poche (10) comprend une structure de raccord de tube unique. Une première partie (14) est montée sur une paroi de la poche. La première partie de raccord (14) comprend un élément de fermeture qui maintient le liquide de manière étanche dans la vessie. Une seconde partie de raccord (18) peut être accouplée à la première partie de raccord (14) et comprend une structure qui sert à déplacer l'élément de fermeture (16) vers une position ouverte lorsqu'elle est accouplée à la première partie de raccord (14). La seconde partie de raccord (18) est profilée pour s'ajuster avec un tube pour boire (20) flexible classique.
