Assembly assembled of a recipient and a retainer, a method for producing the assembly, and a use of the assembly

An assembly of a recipient (2) and a retainer (2) formed as a case (3), the recipient (2) is for receiving objects of different kinds in a using state of the assembly (1), the retainer (3) has an access opening (5), and in a resting state of the assembly the retainer serves (1) for retaining the recipient (2), the recipient (2), before being assembled with the case (3), is formed as a flat-laid flexible tube (2), which has a first and second end part, and which flat-laid flexible tube (2) in the resting state of the assembly is folded up in a predetermined way in the case (3) into at least nearly parallel zigzag folds (9) and (11), which are placed close to and/or are abutting each other, characterized in, that the retainer is formed as a case (3) with an access opening (5) into a cavity which has an area defined by a depth extending into a direction perpendicular to the access opening (5) and a width extending into a direction perpendicular to the direction of the depth, whereby the tube (2) has a larger area than said cavity.
