The container includes a three-dimensional plastic bag (3) filled with liquid diluent, a bottle (9) filled with a perforated cover (26), containing a drug or nutrient substance, a tube (12) extending from the bag, and finally a coupling and perforation device (16) for the bottle cover. The bag is stored in a flexible sealed housing (1),The bottle and the coupling and perforating device are stored in a second sealed elastic solid shell (2). The steel tube (12) includes a section (13) between the first and second housings, which includes an adjustable flow deflector (18), from the first position, to prevent any communication between the bottle and the bag, Until the second position, it is allowed to hedge the bag against the sealed side door (19) (22),Or a third position, let the bottle connect to the side opening. In the other side opening (41) of the flow deflector, a flexible tube (42) is combined with a hydrofluorocarbon filter (43),Finally, one and / or another sealed sealed sealed sealed sealed bag is formed as pressure compensation (Figure 1).El envase comprende una bolsa esteril (3) llena de diluyente liquido, una botella (9) equipada con una tapa perforable (26) que contiene una sustancia medicinal o nutricional y un tubo (12) que se extiende desde la bolsa y termina con un dispositivo de acoplamiento y perforacion (16) para la tapa de la botella. Dicha bolsa se aloja en una carcasa esteril flexible sellada (1), mientras que la botella y el dispositivo de acoplamiento y perforacion se alojan en una segunda carcasa esteril flexible sellada (2). El tubo (12) comprende una porcion (13) entre la primera y la segunda carcasa, que aloja un desviador de flujo (18) ajustable desde una primera posicion en la que impide cualquier comunicacion entre la botella y la bolsa, hasta una segunda posicion en la que permite poner la bolsa en comunicacion con una abertura lateral sellada (19) para una jeringa (22), o una tercera posicion en la que permite que la botella se conec
