  • the arrangement of the base surfaces A1 on the foil bag 2 is rotationally asymmetrical.
  • bag chambers 3 with (possibly strictly) monotonically increasing size of the base surface and / or (possibly strictly) monotonically increasing size of the filling volume can reduce the risk that it is in a washing process to a hooking of laundry parts, such as buttons and / or applications, between adjacent bag chambers 3 comes. As a result, the detergent product 1 is moved more intensively during a washing process and washed around, which ensures good dissolution behavior.
  • the bag chambers 3 are arranged around a non-interrupted sealing section 4 provided in the middle region of the film bag 1.
  • the bag chambers 3 are in the circumferential direction (arrow 12) of the film bag. 2 arranged next to each other and do not overlap each other. All bag chambers 3 have a different filling volume and a different spatial form.

  • the embodiment shown are larger and different for the bag chambers 3.
  • adjacent bag chambers 3 are arranged relative to each other such that the wider convex end portion 6 of the contour of a first bag chamber 3 is opposite to the concave connecting portion 7 of a second bag chamber 3 following in the circumferential direction.
  • the narrower convex end section 5 of the subsequent second bag chamber 3 is offset radially outward relative to the wider convex end section 6 of the first bag chamber 3 with respect to the area bisecting line 10 of the two base surfaces A1 of the adjacent bag chambers 3.
  • the starting point of the area bisector 10 of the base area A1 at the narrow end of a bag chamber 3 following in the circumferential direction of the film bag 2 is offset radially outward relative to the end point of the area bisector 10 of the base area A1 at the wide end of a preceding bag chamber 3.
  • the wider convex end portion 6 of the contour of a preceding bag chamber 3 in the sealing plane intersects a tangent 9 which is placed on the narrow convex end portion 5 and on the wide convex end portion 6 of the contour of a following bag chamber 3, thereby extending into a concave area the following bag chamber 3 inside.
  • the connecting portions 7, 8 of the contours of all the bag chambers 3 in the sealing plane have a same direction of curvature from the narrow convex end portion 5 to the wide convex end portion 6 of the respective bag chamber 3.
  • Fig. 2 follows therefrom in a plan view a right-handed arrangement of the base surfaces A1 of the bag chambers 3 in the direction of the narrow convex end portion 5 to the wide convex end portion 6 (or a corresponding left-handed arrangement in a view from below of the film bag 2 according to Fig. 3 ). It is understood that in a plan view, a left-handed arrangement of the base surfaces A1 of the bag chambers 3 may be provided.
  • the following bag chamber 3 then adjoins with the same or similar cross-sectional profile, wherein the maximum cross-sectional area of the following bag chamber 3 is greater than the maximum cross-sectional area of a preceding bag chamber 3. This applies to the in Fig. 2 above, right and bottom bag chambers 3.
  • the maximum cross-sectional area of the in Fig. 2 The bag chamber 3 shown on the left corresponds again essentially to the maximum cross-sectional area of the in Fig. 2 bottom of bag shown 3.
  • the geometry of the bag chamber 3 or of its envelope is thus both in the two-dimensional space in the sealing plane (in plan view of the base surfaces A1) and in the three-dimensional space (in a perspective view of the bag chambers 3) in the direction of curvature of the area bisector 10 by a helical structure characterized.
  • the maximum width of a base surface A1 or the maximum cross-sectional area of a bag chamber 3 can be achieved in each case in the region of the center of a circular arc placed from the inside on the broad convex end section 6 of the contour line of the bag chamber 3 in the sealing plane.
  • the convex outer connecting sections 8 of the contour lines of the bag chambers 3 of a film bag 2 in the case of the detergent products 1 shown are arranged on a common circumferential line 11 that runs around at least substantially four or more or eight.
  • Other shapes of the circumferential line 11 are not excluded, for example, the circumferential line may be circular. This too contributes to a compact construction.
  • the smallest distance between two bag chambers 2 following in the direction of the circumferential line 11 in the sealing plane may be preferably less than 5 mm, more preferably less than 3 mm, particularly preferably less than 2 mm. Due to the deformations occurring in the production of the film bag 2 by deep drawing and due to restoring forces of the film layers may adjacent Bag chambers 3 in the use state of the detergent product 1 even partially against each other.
  • FIGS. 8 to 14 shown detergent product 1 has three bag chambers.
  • the bag chambers 3 fit together in a ying and yang shape, so that the width of the sealing sections 4 between the bag chambers 3 becomes as small as possible. This achieves a high intrinsic dimensional stability. The perception of the narrow sealing portions between the bag chambers 3 is difficult.
  • the outer connecting portions 8 of the contour of the bag chambers 3 are formed as free-form curved sections.
  • the outer connecting portions 8 lie on a substantially quadrangular common circumferential line 11.
