The invention concerns a container constituted by a receptacle designed to contain a solid product for dialysis and a connector (200) for connecting the receptacle to a dialysis machine, the connector being equipped with a filling channel (202) that crosses it from one end to the other and that enable filling the receptacle with solid product a fluid line (211, 212, 213) for introducing a solution-making liquid into the receptacle, said fluid line extending between a first connecting portion (211) that opens to the outside of the receptacle and an orifice (213) that opens to the inside of the receptacle and a fluid line (221, 222, 223, 224) for extracting the obtained solution from the receptacle, said fluid line extending between a second connecting portion (221) that opens to the outside of the receptacle and an orifice (224) that opens to the inside of the receptacle, the first connecting portion (211) and the second connecting portion (221) serving a means for connecting the corresponding fluid lines to the dialysis machine, The container according to the invention is characterized by the fact that the filling channel (202) is open at both ends and that the two fluid lines (211, 212, 213 221, 222, 223, 224) are fluid-tight between the orifice (213, 224) that opens into the receptacle and the first or second connecting portion (221, 221), respectively.
