Carrying handle bag made of plastic film

The main patent relates to a plastic film carrying handle carrying bag, in which only one Tasehefiwandung is provided with a welded handle made of dimensionally stable thermoplastic plastic, and the other bag wall has a through-slot at the height of the handle base and is extended beyond this through-through through a wrap-around part is that is taken already in the Tasehenherstellung and is welded at its side edges with the side edges of him supporting pocket wall, said the carrying handle supporting Tasehenwandung in which the Umsehlagteil respective edge portion to the Seitensehweißnähten extends before the first use and is detected by this, and in this area between its outer parts covered by the side weld seams and its central part provided with the handle, easily destructible lines of weakness, which are best made of incisions interrupted by only a few, very thin material webs hen can, are provided so that the Tasohenwandung carrying the handle is shortened in the brewing state in the edge area corresponding to the Umsehlagteil after destruction of the thin material webs on both sides so that it is not covered by the side weld seams.

The embodiment of the weakening lines according to the main patent has been made so that they are at the level of the lower edge of the Uraschlagteils on the sides of the

towards the pocket and thus cross the side welds.

It has been shown that the bags in use, in particular when filling or under the influence of bulky filling goods, tear easily at these points, so that they, as these cracks, which start from the inside, run either downwards along the weld seam or through the here only two layers connecting weld seam extending through to the outer edges of the pockets, at least in their appearance, if not their practical value be extraordinarily impaired.

In order to remedy this deficiency, it has already become known (DBGm? 043 762) that the bevels produced by full cuts at the tuck-in flap in the indentations below the lower edge of the flap to leave and to connect to the recesses projections, which extend up to the lower edge of the envelope flap extend and into the edge weld seams that encompass the front and rear wall of the bag as well as the flap, to be included.

This well-known bag may bring a certain improvement, as a tear in the area of here at least three layers and, in the case of a duroh two-layer envelope flap, four layers connecting weld seams will no longer take place so easily, but this can tear the front wall of the bag along the Weld seam downwards also cannot be prevented, in particular not since the front wall naturally has a Outer layer of the weld seam forms and thus not against

Tearing is supported by other layers. As is known, however, the zone of a welded layer is next to the weld the most endangered one, so that damage to the known bag during use cannot be ruled out ' are.

Through the sisia between the below the lower edge of the Envelope flap extending depressions in the tuck-in flap blank and the edge weld seams one piece each parts of the front that are raised far beyond the lower edge of the flap to the inlet into the edge welds The wall of the pocket, which is "on the outside" above the flap even when the tuck-in flap is inserted, are inlet zones for rainwater trickling down on the outside of the flap, so that the contents of the bag are at both edges contrary to the actual purpose of the bag, it can get wet when carrying it in the rain.

The invention is based on the object of fundamentally providing a remedy here, and for this purpose provides for a Carrying handle carrying case according to the main patent essentially that the front wall of the bag carrying the carrying handle shortening lines of weakness in the area of the lower edge of the flap from the weld seams and towards the middle of the pocket to expire indicating.

Due to the inventive cut of the tuck-in flap, when the carrier bag is opened; or as a result of bulky contents occurring tensile forces kept absolutely away from the side seam area, so that neither a tearing of the seam nor the the pocket front wall having the insertion flap can occur along the seam.

There is also the further advantage over the aforementioned known carrier bag that the invention Bags can be made without being punched out

209844/0323

Waste pieces accumulate, their removal from the manufacturing machines because of the static charge on the plastic film makes extraordinary difficulties and expensive Action required.

Finally, the carrier bags according to the invention are also tight, since they are located on both sides over the flap extending, standing parts of the front pocket wall extend to the upper edge and are welded here so that openings into which rain can penetrate do not remain.

According to a further embodiment of the invention, the incisions can also be in an upward direction towards the pocket opening pointing direction are continued, so that hereby the run-out of the incisions runs in and not transversely to the direction of stress, whereby a further tearing with certainty is avoided.

The incisions, which are interrupted by a few, very thin material webs according to the main patent, preferably run from the upper edge, first vertically downwards, and then to go over in a curved course in their main direction to diverge downwards.

The course, which begins at right angles to the upper edge, creates practical tips on the remaining outer parts avoided. The insertion of the tuck-in flap is made easier by the diverging course.

If a-particularly effective anchoring of the upper Corners of the tuck-in flap behind the flap is desired in order to prevent the welded strip of the The handle is usually no longer held corners of the plug-in

2098U / 0323

flap are not pushed out under the action of the product, a downwardly converging blank came the push-in flap.

According to a further proposal of the invention, the cut of the plug-in flap can diverge downwards from the upper edge and then run in the shape of an arc of a circle, which makes it easier to insert under the flap, and on the other hand due to the central part of the tuck-in flap, which has been broadened by the fillet, good anchoring underneath the envelope flap is ensured.

Finally, however, the incisions can also run essentially parallel to the side weld seams.

In all embodiments of the weakening lines, which can be formed by incisions, which are only made by very few, for example, are only bridged by a narrow material web, according to the invention is pointing towards the middle of the pocket The end of the cut is curved to avoid any tears.

If material bars are to be dispensed with entirely, this is impaired this is not the effect of the invention. The material webs only offer the advantage that the flap is open until use the bag is held on to it during packaging, shipping and storage and does not fall down or can slip, which is of course disadvantageous.

The invention is explained in more detail in the following description with reference to the drawing. In the drawing show:

The carrying bag consists of the front wall 1, the rear wall 2 and the flap 3 formed from an extension of the rear wall 2 with the push-through slot 4 for the on the front wall 1 attached handle 5 »The front wall, the back wall and the flaps are connected to one another on the sides of the carrier bag by the welded seams 6 and 7. The front wall forms the tuck-in flap 9 in its upper part, which extends essentially to the lower edge 8 of the flap. which is tucked under the flap after the bag has been filled, after which it is closed in a rain- and dust-tight manner Bag can be carried on the handle penetrating through the slot.

The push-in flap 9 is further laterally bounded by weakening lines Io and 11, so that it is separated from the side weld seams is not included and is freely movable for insertion after these lines of weakness have been destroyed. As shown, the lines of weakness can be formed by incisions be, each bridged only by a thin web 12 of material are. The total of two material bars are sufficient to hold the tuck-in flap on the bag until it is used. If this is not important, the bars can be omitted entirely and pure incisions can be made.

2Q98U / 0323

The lo outside the lines of weakening or cuts, ll remaining corner pieces 13.1 ¹ I of the front wall are out of their attachment in the side weld seams by further short embracing all layers welds 15 and 16 rain and dust-proof connected to the bag top edge.

The weakening lines or incisions lo, ll running out in the area of the flap lower edge 8 are from the Side weld seams directed towards the center of the pocket and denoted by 17 on this section in FIG. The lowest point of the section 17 should be almost exactly at the level of the lower edge 8 of the envelope flap, in order to also be here not to leave an opening for the ingress of dust or moisture. The drawing has been used for clarification of the course of the cut deviated from this and point 17 was placed a little lower.

Expediently, the section 17 is followed by a last section 18, which is directed towards the pocket opening is. As a result, the end of the incisions that is most at risk of tearing runs in the pulling direction, see above that transverse forces, which would cause further tearing, do not occur here under loads. Are advantageous the sections 17 and 18 and the transition 19 to the rest of the section are arcuate to avoid any risk of tearing largely off. Since the lines of weakness or incisions are neither like in a known carrier bag the side welds cross yet reach the weld edge, cracks are along or across the Side welds excluded.

The rest of the course of the weakening lines or incisions lo, ll can correspond to the special requirements or wishes can be chosen at will. For easy insertion of the tuck-in flap, it is tapered towards the top advantageous. This is in the preferred embodiment the case is most pronounced according to FIGS. 1-4. However, to a

209844/0323

unsightly and unsuitable point on the corner parts 13.1 * 1 To avoid this, the cuts in their upper part 2o are again upright.

If on the convenient insertion of the tuck-in flap in favor of a better anchoring of their no longer of the Welding bar 21 of the handle 5 held corner parts should be dispensed with in order to move these corner parts out to avoid by the filling material, the course of the cuts j as shown in Figure 5, diverging upwards be trained. In this case, the additional weld seams 15, 16 are also unnecessary.

The embodiment according to FIG. represents, in which the course of the cut is convex pointing outwards is held, whereby the tuck-in flap tapers in its upper part for easy insertion under the flap and is made wide in its central part for good anchoring.

Finally, in accordance with FIG. 7, there are also essentially vertical, parallel to the side weld seams Weakening lines or incisions can be carried out where the corner parts 13,1 ^ are as small as possible and the tuck-in flap should be made as wide as possible.
