DETAILED DESCRIPTION

[0048] FIG. 1 is a schematic perspective view of a plastic bag 1 according to the present disclosure. Said plastic bag comprises a bag base 2 having a bag base fold 36 and an opposite bag opening 4, and comprises a front wall 6 and a rear wall 8, each having a first side edge 10, 10, an opposite second side edge 12, 12, an opening edge 14, 14, and a base edge 16, 16. In the embodiment shown, the front wall 6 and the rear wall 8 are interconnected in the region of the first 10, 10 and second side edges 12, 12 and the base edges 16, 16 thereof by means of welding so as to form a first bag edge 18, a second bag edge 20 and a bag base edge 22. In the embodiment shown, the front wall 6 has, on the inside, a plastic film layer 24 that extends from the first side edge 10 towards the second side edge 12 and extends from a point spaced apart from the base edge 16 towards the opening edge 14, the plastic film layer 24 having two welded or adhesively bonded areas 26, 28 that are connected in portions to the inside of the front wall 6 and form internal bag inserts 30, 32 and 34, which are open towards the bag base 2. By way of example, a beverage bottle is shown being held in the internal bag insert 34. Furthermore, in the embodiment shown, the rear wall 8 is likewise provided with a plastic film layer (not shown) on the inside in a similar manner.

[0049] The embodiment of the plastic bag I according to the present disclosure shown here further comprises, on the inside of the front wall 6 and the rear wall 8, a hem 38, 38 that is formed by folding over continuation portions 42, 42 on the front wall 6 and the rear wall 8, respectively. The hems 38, 38 are respectively connected to the inside of the front wall 6 and the rear wall 8 by continuous longitudinal welds 40, 40. Furthermore, the embodiment of the plastic bag 1 according to the present disclosure shown here comprises, on the front wall 6 and the rear wall 8, holding straps 44, 44 that are attached to the inside of the reinforced hem 38, 38 by a first connecting region 46, 46 and a second connecting region 48, 48. Moreover, the shown plastic bag 1 has triangular cut-outs 50, 50, 52, 52 on the bag base 2.

[0050] FIG. 2 is a schematic plan view of the embodiment of the plastic bag 1 according to the present disclosure according to FIG. 1. The plastic film layers 24, 24 are respectively connected to the inside of the front wall 6 and the rear wall 8 by welded or adhesively bonded areas 26, 26, 28, 28 such that a total of six internal bag inserts 30, 30, 32, 32, 34 and 34 are formed for receiving six beverage bottles. If there are no bottles in the internal bag inserts 30, 30, 32, 32, 34, the plastic film layers 24, 24 rest against the inside of the front wall 6 or the rear wall 8 and do not hinder the ordinary filling of the plastic bag 1.

[0051] FIG. 3 is a schematic plan view of a further embodiment of a plastic bag 1 according to the present disclosure. Said plastic bag differs from the embodiment according to FIG. 2 in that the welded or adhesively bonded areas 26, 26, 28, and 28 are not formed as punctiform or continuous welds or bonds to the front wall 6 or rear wall 8, but as separate film partitions, which allows larger beverage bottles or beverage bottles having a larger volume to be held.

[0052] FIG. 4 is a schematic view of an alternative embodiment of a plastic bag 1 according to the present disclosure. Said plastic bag differs from the embodiment according to FIG. 1 in that the first side edges 10, 10 and second side edges 12, 12 of the front wall 6 and the rear wall 8 are interconnected, in some cases welded to one another, by a first side wall 11 and a second side wall 13. The first bag edge 18 and the second bag edge 20 are accordingly formed by the center lines of the first side wall 11 and the second side wall 13, which extend from the bag base 2 as far as the bag opening 4.

[0053] FIG. 5 is a schematic plan view of the embodiment of the plastic bag 1 according to the present disclosure according to FIG. 4. The plastic film layers 24, 24 are respectively connected to the inside of the front wall 6 and the rear wall 8 by welded or adhesively bonded areas 26, 26, 28, 28 such that a total of six internal bag inserts 30, 30, 32, 32, 34 and 34 are formed for receiving six beverage bottles.

[0054] FIG. 6 is a schematic plan view of a further embodiment of a plastic bag 1 according to the present disclosure. Said plastic bag differs from the embodiment according to FIG. 5 in that the welded or adhesively bonded areas 26, 26, 28, and 28 are not formed as punctiform or continuous welds or bonds to the front wall 6 or rear wall 8, but as separate film partitions, which allows larger beverage bottles or beverage bottles having a larger volume to be held.

[0055] FIG. 7 is a schematic view of a highly expedient, alternative embodiment of a plastic bag 1 according to the present disclosure. Said plastic bag differs from the embodiment according to FIG. 1 in that a welded or adhesively bonded area 54 is present in the form a weld seam for fastening the plastic film layer 24 adjacently to the first side edge 10, said weld seam having a spacing from said first side edge 10 that is smaller, in some cases smaller by approximately half, than the spacing between the welded or adhesively bonded area 26 and the welded or adhesively bonded area 54, between the welded or adhesively bonded area 26 and the welded or adhesively bonded area 28, and also between the welded or adhesively bonded area 28 and the welded or adhesively bonded area 56, each in the form of a weld seam. Furthermore, the welded or adhesively bonded area 56 in the form of a weld seam for fastening the plastic film layer 24, said area being adjacent to the second side edge 12, has a spacing from said second side edge 12 that is smaller, in some cases smaller by approximately half, than the spacing between the welded or adhesively bonded area 26 and the welded or adhesively bonded area 54, between the welded or adhesively bonded area 26, and the welded or adhesively bonded area 28, and also between the welded or adhesively bonded area 28 and the welded or adhesively bonded area 56, each in the form of a weld seam. The plastic film layer 24 of the rear wall 8 can be connected to the inside of said rear wall in the same way as described above for the front wall. For reasons of better clarity, this is not shown in FIG. 7, but in FIG. 8.

[0056] FIG. 8 is a schematic plan view of the embodiment of the plastic bag 1 according to the present disclosure according to FIG. 7. The plastic film layers 24, 24 are connected to the inside of the front wall 6 and the rear wall 8 by welded or adhesively bonded areas 26, 26, 28, 28 and 54, 54, 56, 56, each in some cases in the form of weld seams, such that a total of six larger internal bag inserts 30, 30, 32, 32, 34 and 34 and four smaller internal bag inserts 58, 58, 60, 60 are formed. By the four smaller internal bag inserts remaining unused, there is regularly still enough storage space for receiving further products between the plastic film layers 24, 24, even when bottles are held in the larger internal bag inserts.

[0057] The features of the present disclosure disclosed in the above description, the claims, and the drawings may be essential either individually or in any desired combination for carrying out the various embodiments of the present disclosure.

[0058] Furthermore, the various embodiments described above can be combined to provide further embodiments.
