A plural-compartment medical container, wherein said container is a pouch formed of a synthetic resin and has an open member at least one end of upper and lower ends thereof for filling or withdrawing a drug solution, and the inner surface of said container is divided into plural compartments in a liquid-tight manner by a blocking seal portion, characterized in that when a melting temperature curve of a resin of said blocking seal portion is determined using differential scanning calorimeter, a height ratio (h2/h1) between a height (h1) of a peak at a temperature of main melting peak and a height (h2) of said temperature curve at a temperature of 115°C, is within a range of 0.05 to 0.4, the blocking seal portion thereof peeling well by pushing operation to the pouch, provides a plural-compartment medical container having excellent flexibility and transparency.

L'invention concerne un récipient en forme de sac en résine synthétique comportant un élément à orifice de chargement ou de déchargement de médicament liquide et au moins des extrémités supérieure et inférieure du récipient. La surface interne du récipient en forme de sac est divisée de manière étanche aux liquides en plusieurs chambres par un élément de blocage scellant. L'objet de l'invention se présente notamment comme un récipient médical à chambres multiples qui manifeste une souplesse et une transparence excellentes et une capacité de libération du blocage scellant sous pression, à l'instar d'un sac; il est caractérisé en ce que la résine utilisée dans l'élément de blocage scellant a un rapport des hauteurs (h2/h1) compris entre 0,05 et 0,4, (h1) représentant une hauteur de pointe à une température de fusion de pointe sur une courbe de température de fusion mesurée au moyen d'un calorimètre à balayage différentiel et (h2) représentant une hauteur sur la courbe de température à 115 DEG .
