The present invention is a medical liquid medicine container (13) formed of a resin film which includes seal layers. The medical liquid medicine container (13) comprises: a plurality of liquid medicine storage rooms (15, 16) into which the medical liquid medicine container is divided and which can communicate with each other a discharge spare room (17) formed with an outlet which discharges the liquid medicine a liquid-tight dividing member (18) which divides the container (13) into the plurality of liquid medicine storage rooms (15, 16) so as to become liquid-tight each other and a non-liquid-tight dividing member (19) which divides the container (13) into at least one (16) of the plurality of liquid medicine storage rooms and a discharge spare room (17) so as to become non-liquid-tight each other. The non-liquid-tight dividing member (19) has fine pores via which a slight amount of the liquid medicine or water in the liquid medicine passes to the discharge spare room (17) and detachablely seals the seal layers with each other and a melting point of the seal layers is no less than 130℃ and the seal layers are made of one or more resins elected from a group consist of homo polypropylene, random polypropylene and high density polyethylene.本發明,係由具備有密封層之樹脂薄膜所形成之醫療用藥液容器(13)。該醫療用藥液容器,係具備有:可連通地被劃分之複數個藥液收納室(15、16)、及形成有藥液的排出口之排出預備室(17)、及將上述複數個藥液收納室(15、16)相互液密地予以劃分之液密劃分手段(18)、以及將上述複數個藥液收納室(15、16)中之至少1個(16)與上述排出預備室(17)之間非液密地予以劃分之非液密劃分手段(19);上述非液密劃分手段(19),係具有:微量的上述藥液或者藥液中的水分可往上述排出預備室(17)透過之細孔(19a),且將上述密封層彼此可剝離地予以密封;上述密封層,係熔點為130℃以上,且由:由均聚聚丙烯、無規聚丙烯、高密度聚乙烯所構成之群所選的1種以上之樹脂所形成。10...藥液袋11...第1藥液12...第2藥液13...醫療用藥液容器15...第1藥液收納室16...第2藥液收納室17...排出預備室18...液密密封(液密劃分手段)19...非液密密封(非液密劃分手段)19a...細孔19b...密封部21...排出口
