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,
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.

1. A container comprising: a first side wall and a second side wall, the first and second side walls permanently joined by first and second opposing seam sides, and a third seam side extending between the first and second seam sides, such that a chamber is formed between the side walls;a first protrusion having a first curved portion and extending from the first seam side into the chamber;a second protrusion having a second curved portion and extending from the third seam side into the chamber; anda peelable seal separating the chamber into a first sub-chamber capable of receiving a first liquid content and a second sub-chamber capable of receiving a second liquid content, thereby allowing, if the peelable seal is opened, a liquid content of the first sub-chamber to be mixed with a liquid content of the second sub-chamber, wherein the peelable seal overlaps and intersects the first and second curved portions of the first and second protrusions, respectively, and wherein at least one of the first protrusion and the second protrusion is loop-shaped. 2. A container according to claim 1, wherein at least one of the first and second protrusions protrudes into the chamber from an edge portion of the seam. 3. A container according to claim 1, wherein at least one of the first and second protrusions is arranged at an end of an elongated section of the seam that extends into the chamber. 4. A container according to claim 1, wherein the first side wall and the second side wall are not joined at a section enclosed by the loop. 5. A container according to claim 1, wherein each of the first protrusion and a portion of the second protrusion is loop-shaped. 6. A container according to claim 1, wherein a section of the peelable seal is, in a direction towards the second sub-chamber, offset from a line that extends between a first end point (P1) of the peelable seal and a second end point (P2) of the peelable seal. 7. A container according to claim 1, wherein the second sub-chamber is capable of containing a liquid to a relatively larger extent than the first sub-chamber. 8. A container according to claim 1, comprising a second peelable seal that separates the chamber into the first sub-chamber and a third sub-chamber capable of receiving a third content, thereby allowing, when the second peelable seal is opened, a content of the third sub-chamber to be mixed with a content of the first sub-chamber. 9. A container according to claim 8, wherein the second peelable seal is configured to separate the first and the third sub-chambers such that a volume of the first sub-chamber is at least six times greater than a volume of the third sub-chamber. 10. A container according to claim 1, wherein the first sub-chamber is capable of containing a first liquid content, the second sub-chamber is capable of containing a second liquid content, and a mixture of the liquid contents forms a dialysis solution. 11. A method for mixing contents of a container that comprises a first side wall and a second side wall permanently joined to the first side wall by first and second opposing seam sides, and a third seam side extending between the first and second seam sides, such that a chamber is formed between the side walls, a first protrusion having a first curved portion and extending from the first seam side into the chamber, a second protrusion having a second curved portion and extending from the third seam side into the chamber, where a peelable seal separates the chamber into a first sub-chamber comprising a first liquid content and into a second sub-chamber comprising a second liquid content, and where the peelable seal overlaps and intersects the first and second curved portions of the first and second protrusions, respectively, and wherein at least one of the first protrusion and the second protrusion is loop-shaped, the method comprising: pressing on the second sub-chamber such that the peelable seal opens; andrepeatedly pressing on each of the first and the second sub-chambers for allowing the first liquid content and the second liquid content to be mixed in the chamber.
