Abstract: A container including a first side wall and a second side wall that are permanently joined by at least one seam such that a chamber is formed between the side walls. A peelable seal separates the chamber into a first sub-chamber and a second sub-chamber that are capable of receiving liquid contents, which may be mixed if the peelable seal is opened. The seam includes a protrusion that extends into the chamber, and the peelable seal extends over the protrusion.

Abstract: The invention concerns a fluid bag that contains either dialysis fluid for hemodialysis or a replacement fluid for replacing ultra-filtrate that is withdrawn from a patient or a fluid that is a rest product from a process of hemodialysis or the like. The fluid bag has a first main sheet and a second main sheet located opposite to the first main sheet. The fluid bag is sized to contain at least a certain quantity (q) of fluid, measured in ml, when it is completely filled with fluid. The fluid bag is configured so that the distance between the first and second sheets never exceeds a certain value (v), measured in mm, wherein: q?2000, and v?2q/100. The invention also concerns a fluid bag assembly including one or more such fluid bags as well as a system including one or more such fluid bags.
