The invention relates to a carrier bag made of plastic film with grip holes and such a reinforcement upper edge of the bag that the bag retains its rectangular shape when carried substantially.

From French patent specification 1 123 728 is a handle hole carrying bag with a flap and a Known through the pocket walls and the flap passing handle hole, the handle hole in the Bag walls is reinforced by glued-on sections. It is also from the. Documents of the German utility model 1 854 132 already known / for plastic bags, However, those without a grip hole, fix a closure flap on the side of the back wall of the bag by means of welds and shorten the front wall of the bag laterally, so that it is not covered by the side welds and forms a flap that can be inserted under the closure flap after the bag has been filled. The German Utility model 1 913 263 describes a carrier bag

with provided in both pocket walls, with each other aligned handle holes and provided above these handle holes, over the entire width of the pocket extending support and stiffening strips with the Bag material are in one piece.

Based on these known features, there is already a handle-hole plastic carrier bag on the market, which has an envelope, fixed in the side welds and covering the bag opening, of one bag wall / under which the other bag wall, which is not covered by the side welds in the insertion area due to lateral gusset punchings, can be inserted. the The punched grip hole extends through the three material layers in the grip hole area, with all three walls in the grip hole area at the upper edge of the bag to increase the load-bearing strength and the dimensional stiffness Much stronger material than the rest of the bag material can be formed. The much stronger material provided in the upper edge area is by means of overlaps and welds in a special operation to the material forming the remaining part of the pocket scheduled.

Despite the considerable amount of material required for the three-layer envelope and grip hole area made from strong film material, and despite the increased amount of work required by the attachment, it is capable of doing this not to satisfy this well-known carrier bag, because the result of its intended use for packaging Textile wide carrier bags of the type described are not in their upper area despite the elaborate design

sufficiently stiff so that even with the filled carrying bag the upper corners sink in an unsightly way. Even with the carrier bag according to utility model 1 913 263 there is a considerable arching of the support strips made of plastic when worn.

The present invention is based on the object to design a plastic carrier bag of the type described at the beginning so that the bag, if avoided A 2u large amount of material and work in the bearing area can cope with all loads and at their upper Edge is so stiffened that the corners can never sink.

To solve this problem, a carrier bag made of plastic film with provided in both bag walls, aligned handle holes and provided above at least one handle hole, located in the proposed essentially over the entire width of the pocket extending support and stiffening strip, as a support and stiffening strip to weld on a metal rail surrounded by a weldable plastic jacket.

Such a plastic-coated metal rail requires relatively little expensive plastic and can be chosen thin, because the metal is still stiff enough due to its high strength both in the grip area as well as along the edge of the bag. The metal rails are also straight so that they come out from the bottom Slightly slide out stacks stored in a magazine individually for connection to the pocket material.

as is the case with rigid plastic handles "already is known. Thanks to the plastic coating, then weld the strips to the bag material in the manner known for the above-mentioned carrying handles.

In a manner known per se, the carrier bag can have an envelope that covers the pocket opening when the bag is filled, the envelope also having a grip hole. It is useful if the carrying ^? ind stiffening strip is attached to the pocket wall that does not have the envelope part, because after pulling the bag and inserting the free wall part under the envelope it stiffens the two walls in the upper edge area, while when the metal rail is attached to the wall provided with the envelope a corresponding cut of the free wall part to be inserted would have to be taken so that it cannot hang down on the sides. In addition, the bar attached to the free wall as a handle makes it much easier to insert this wall part under the envelope. The bar can, however, also be arranged on the other wall of the pocket or on the envelope.

The inventive carrying bag made of weldable plastic film with a front wall 1 and a Rear wall 2 and side welds 3 and 4 is on the rear wall 2 with an inward flap and handle lochaus punchings 6 provided through both walls and the envelope. Above the grip hole

punched out 6 is a support and stiffening strip 7 on the inside of the pocket front wall by means of a weld seam 8 welded on. The bar "7" consists of a steel rail 9, which is supported by a jacket IO made of weldable plastic is surrounded, which, however, does not cover the rounded end faces 11.

The front pocket wall is at least to the depth of the envelope 5 with next to the weld seams, up to expediently converging, interrupted by small remaining material webs 12 Sections 13 and 14 provided. When the pocket is opened, the material webs, which are designed as predetermined breaking points, are removed 12 easily destroyed and is formed by the cuts 13 and a flap 15, "which after filling the bag among those included in the side welds 3 and 4 Envelope 5 can be inserted, as shown in FIG.

The pocket rests with the strip 7 in the hand shown in FIG of the girder, whereby the bar has the load bearing capacity evenly over the due to its high bending stiffness her attached front wall 1 and by means of the envelope 5 hanging over the bar and by the grasping hand distributed rear wall 2 prevented from slipping back. In addition, the bar 7 holds the * upper edge of the carrier bag always straight so that the upper corners do not sag and give the bag an ugly appearance when carried can.

If necessary, instead of the interrupted cuts 13 and 14, full cuts can and can also be made the material lying outside the cuts is removed before the side welds 3 and 4 are made, whereby the remaining flags 16 and 17 avoided, but the disadvantage is accepted that the Flap 15 is not held during and after the manufacture of the bag. This complicates the production because the flap is no longer held in the material web and the tension in the material web is released, also because the separated material parts have to be removed. Even when handling the bag up Due to the tab that is not held, some interference can arise in relation to its use, since the As a result of gravity, the groin strained the flap in its prescribed flat position on the pocket at every opportunity leaves.

FIG. 7 shows various other options for attaching the support and weld-on strip 7:
