DETAILED DESCRIPTION OF THE INVENTION

(6) A packaging for filler materials is designated as 1; this has a front wall 2, a rear wall 3 and a stand base 4. Here the stand base 4 is created by the folding in along a longitudinal face of at least one tubular web section folded in the longitudinal direction. Thus in its flat state the packaging is appropriately formed with four layers in its base region 5. Moreover the packaging likewise has a four-layer header region 6, which is created by a fold-over 7 of the front wall 2 turned over at its upper end to form a multi-layer region, and the fold-over 8 of the rear wall 3 turned over the multi-layer region. In this form of embodiment the four layers in the header region 6 of the packaging are joined together via a joining seam 9, so that the header region 6 is separated from the fill space 10 for the filler material. In addition a carrying aid 11 is provided in the header region 6 separated from the fill space 10; this is formed as a perforation penetrating all layers in the header region. Here the carrying aid has, for example, an advantageous size such that it can be gripped by at least the fingers of one hand. The packaging 1 is closed on its faces via side seams 12, 12 formed as welds, wherein each side seam joins together all four layers in the base region 5 and header region 6, and in the section between head and base region joins together the front wall 3 and the rear wall 3. For increased stability of the stand base 4 the packaging 1 in the base region has corner welds 13, 13, which join the inner layers created by the folding in of the tubular web section with the inner faces of the front and rear walls. In addition a predetermined separation line 14 is formed in the front wall 2 of the packaging 1 underneath the header region 6, by means of which a removal region, i.e. a removal opening 15, is created for the filler material. Here the predetermined separation line 15 extends parallel to the joining seam 9 from one side seam 12 across to the other side seam 12.

(7) FIG. 2 shows a further inventive example of embodiment of a packaging 21, which likewise has a front wall 22 and a rear wall 23. Front and rear walls 22, 23 are likewise joined together via a stand base 24 in the base region 25. In the header region 26 fold-overs 27, 28 are provided at the upper ends of the front and rear walls 22, 23 in each case. Here in this example of embodiment the two upper ends of the front and rear walls 22, 23 are folded over together so that the inner faces of the walls in the header region lie one upon another. Only three of the four layers in the header region 26 are then joined together by means of the joining seam 29, so that at least one sealed closure of the packaging 21 is ensured, and moreover the fold-overs 27, 28 are fixed on the outer face of the front wall 22. In addition an additional joining seam 30 is provided in the header region, by means of which only a sub-region 31 of the header region 26 is separated from the fill space 32 of the packaging 21. In the sub-region 31 of the header region 26 separated from the fill space a carrying aid 33 is again provided, by means of which the transport of the packaging 21 is simplified. Instead of a perforation penetrating all four layers of the header region only two of the four layers are penetrated, as a result of which a kind of grip is formed. In addition the packaging 21 is again closed on its faces via side seams 34, 34 and has corner welds 35, 35 in the region of the stand base. A predetermined separation line 36 is formed underneath the header region 26; this originates from the side seam 12 and extends over a section in both the front wall 22 and also the rear wall 23, by means of which a removal region 37 is created for the filler material located in the packaging 21. In addition in the removal region 37 a reclosable device 38 is arranged, by means of which the packaging 21, after partial removal of the filler material, can be closed once again. In order to seal the removal region a closing seam 39 is provided, which connects the closing parts of the reclosable device 38 with the inner faces of the front and rear walls 22, 23 and in addition seals the removal region 37 from the fill space 32.

(8) FIG. 3 represents in particular a partial view of the packaging as per FIG. 1; in particular this is designed to illustrate the structure in the header region 6. As can be seen from FIG. 3, front and rear walls 2, 3 in the header region have fold-overs 7, 8, wherein the upper wall section of the front wall 2 is folded over upon itself and thereby a multi-layer region 16 is created. The inner face of the upper wall section of the rear wall 3 is directly folded over upon the multi-layer region 16, so that an overlap region 17 ensues between the upper wall sections of the front and rear walls 2, 3. In the present example of embodiment the upper wall section of the front wall is folded such that surface area sections of the inner faces are laid one upon another so as to form the multi-layer region 16. In this case the joining seam 9 joins all layers in the header region 6 together, as a result of which the latter is separated from the fill space 10 (FIG. 1).

(9) FIG. 4 represents a partial view of the packaging 21 as per FIG. 2. The upper wall sections of the front and rear walls 22, 23 are folded over together and have fold-overs 27, 28 in each case. In this embodiment the upper wall section of the rear wall 23 is here likewise folded over upon itself so as to form a multi-layer region 40. The upper wall section of the front wall 22 with its inner face is now folded over upon the multi-layer region 40 so as to form the overlap region 41. In this embodiment, however, surface area sections of the outer face of the rear wall 23 are laid one upon another so as to form the multi-layer region 40. Front and rear walls 22, 23 are thus in direct contact with one another in each case via their inner faces. The joining seam 29 provides a material bond between the folded-over sections of the front and rear walls, so that the packaging 21 is securely closed. In addition only the fold-overs 27, 28 are fixed on the outer face of the rear wall 23 via the joining seam 29. Only by means of the additional joining seam 30 is a sub-region 31 created, separated from the fill space 32 (FIG. 2) for a carrying aid 33 to be formed in the header region 26.
