Description

The invention relates to a carrier bag made of a plastic film material, with a pocket area, with a closure area and with a handle area, the film material in the area of the pocket being two-ply and the two layers of film material at least on the two longitudinal edges of the pocket area connected to one another in particular by means of longitudinal welds they are.

Carrier bags of the type mentioned are already from practice in many cases knows. The film material of the known carrier bags is usually in one layer, is placed on top of each other to produce a carrier bag and ver at the edges welds so that the pocket area for those to be inserted into the carrier bag Goods results. A disadvantage of the known carrier bags is that the carrier bag Press very hard in the grip area in the hand of the user if other goods are to be transported. In addition, there is the known carrier bags Danger of tearing in the handle area when the goods are heavy.

In addition to the very simple carrier bags described above, there are more complex ones Carrying bags that use a hard plastic handle attached to the Ta area is welded on. The advantage of such carrier bags is that heavy goods can hereby be carried without the risk that the bag quickly tears. In addition, the hard handles have a relatively wide circulation area, so that these handles are not so in the heavier goods Push the user's hand in as is the case with the simple ones described above Carrier bags is the case. A disadvantage of the known carrier bags with a hard handle However, it is that the production is relatively complex, precisely because of the hard grip and accordingly the cost of such tote bags is relatively high. A white Another disadvantage of such hard-grip carrier bags is that they are due to the Hartgriffs can not be fully folded.

Finally, there is a disadvantage of both the simple and initially described also the hard-grip carrier bags in that frozen food that in such a stretcher bags is transported, thaws and spoils very quickly.  

The object of the present invention is a carrying bag of the type mentioned To provide a type that can be produced easily and inexpensively, offers a high level of comfort and the rapid melting of the stretcher bag of frozen food transported is prevented or in any case delayed.

The previously derived and described task is the one with a carrier bag gangs mentioned essentially solved according to the invention in that the Foli enmaterial is multilayered and at least a first, the pocket interior facing layer and a second outer layer. The multilayer speed of the film material offers a number of advantages, some of which are significant. By the multilayer is first of all ensured that the carrier bag is under control area is grippier or fuller, so that the grip area when wearing sweat less pressing into the user's hand. Beyond that the forces that the carrier bag can absorb due to the multilayered nature of the Foil material increased so that the risk of tearing is reduced. The multi-layer activity of the film material leads to the fact that the Trageta invention cal has an improved heat-insulating effect, so that frozen foods last longer can be transported without the risk of immediate thawing. The Isolation is otherwise particularly good if between the individual An air cushion is provided for layers of the film material.

Preferably there is the inner layer that is in direct contact with the goods, from an HDPE. This material gives the tote bag a certain stiffness and tear resistance. In contrast, the second, outer layer consists of an ins special PE coated with aluminum. This results in a high gloss Outside of the carrier bag, which on the one hand reflects the direct sunlight and thus further improves the heat-insulating effect of the carrier bag and the on the other hand, offers an attractive advertising space that prints according to customer requirements can be.

In a particularly preferred embodiment of the present invention the film material has a third layer between the first and the second Layer is arranged. The third layer itself contributes to the tear strength of the film material and thus the carrier bag and at the same time the heat  insulation compared to a two-layer film material is improved. Especially it is preferred in this context that the third layer consists of one foamed PE is there to make the tote bag overall fuller. Is too this material is very heat insulating.

In order to further improve the tightness of the tote bag according to the invention and the To design the carrier bag more stable in the upper opening segment, the Closure area at least one preferably over the entire width of the Carrying bag extending snap closure. The pressure lock is preferred with a provided on one side, first closure part with an intermediate two elastic legs provided groove and one on the other side seen second closure part with a further pushable into the groove Provide thighs. With such a pressure lock can be quickly and close the tote bag according to the invention in a simple manner.

The invention further relates to a carrier bag of the type mentioned, wherein the closure region is preferably formed by the film material Envelope extending over the entire width of the carrier bag.

Carrying bags of the aforementioned type are also known in the prior art. These are carrier bags of the type described above, which are hard have a grip. In such carrier bags, the connecting web extends Hard handle for attachment to the pocket area often only over part of the width the tote bag. In order to be able to completely close the carrier bag, however, is the previously mentioned envelope provided. At the transition from the pocket area to the um there is a slot through which the handle section of the hard handle passes can be inserted. On the disadvantages of this known carrier bag is previously be already been received.

The object of the present invention is therefore also to carry a bag to provide before mentioned type, the simple and inexpensive herge can be placed and which is very comfortable to wear.  

This object is essentially achieved in that the Griffbe rich in the upper area of the pocket on opposite sides ste and has a second handle opening and a third handle opening in the envelope and that the first, second and third handle openings are arranged and designed in this way det are that they are at least essentially in the closed state of the carrier bag Chen are aligned with each other. The carrying bag according to the invention offers first of all the advantage that they are in contrast to a hard-grip carrying case can be produced relatively easily and inexpensively. Since no hard grip is required, lets this tote bag folds up easily. It also results through the envelope and in that the envelope with its handle opening part of the Grip area is an enlarged contact area in the handle area, so that there is a more comfortable wearing results. Incidentally, it is in the invention that due to the Formation and arrangement of the individual handle openings of the locking area and the carrying area merge directly into one another, these areas being common form the actual handle or grip area of the carrier bag according to the invention.

The carrying bag described above is particularly suitable in connection with the embodiment described above. Through a multilayered film enmaterials results in a simple design with only two layers in closed condition of the carrier bag a six-layer structure, when used three layers of the film material even a nine-layer structure, where resulting in a very full grip area that the wearing of the invention Carrying bag makes it very comfortable.

In a preferred embodiment of the present invention, the film is material on the side of the pocket area in the Be rich in two-layer handle opening. In this embodiment, the grip area is like this even four layers of the film material and thus at least eight, preferably even twelve Layers provided, which further increases the grip of the grip area. The one before The second layer mentioned is preferred by a further, a fourth handle envelope having an opening, which, however, is not - like the one at the beginning written envelope - can be opened, but is firmly attached to the pocket area, namely via cross welding. The further envelope is not only used for Improve the grip area, but also represents a reinforcement of the upper en  of the pocket area, so that the risk of tearing when inserting Goods in the carrier bag in this area is significantly reduced.

In a further particularly preferred embodiment of the invention, the film is material also in the area of the (third) handle opening of the envelope in two layers, whereby it is preferred that the two-ply is formed by another envelope and that the further envelope is cross-welded to the actual one Envelope is firmly attached. Considering this embodiment all other envelopes are possible with a two-layer film material a layer structure with ten layers and with a three-layer film material to get fifteen layers. It is understood that the grip area with such high number of layers forms a very large contact surface, which makes wearing the Carrying bag according to the invention makes very comfortable.

Basically, it is possible to separate the pocket area by two of the foils to be formed, which are along the longitudinal edges and at the bottom other welded. However, it is preferred that the film material for formation of the pocket area is only turned over.

It is particularly preferred, moreover, the entire carrier bag from one and the same ben piece of film material. This is also mentioned with the individual previously th envelopes and other envelopes are easily possible.

Fig. 10 is a plan view of a blank for a Trageta cal invention.

In the individual figures, a carrier bag 1 is shown made of a film material 2 , which is preferably made of plastic. The carrier bag 1 , which is shown in Fig. 1 in the open and in Fig. 2 in the closed state, has a pocket area 3 , a closure area 4 and a handle area 5 . As can be seen in particular from FIG. 8, the film material 2 has two layers in the area of the pocket area 3 , the two layers of the film material 2 being connected to one another at least at the two longitudinal edges 6 , 7 of the pocket area 3 via longitudinal welds 8 .

As can be seen in particular from FIGS. 1, 2, 4, 8 and 9, the closure region 4 has an envelope 9 formed by the film material 2 and extending over the entire width B of the carrying bag 1 , which, as can be seen in FIG. 1 results to open the carrier bag 1 and is turned over to close the pocket area 3 , as shown in FIG. 2.

It is essential in the case of the carrier bag 1 that the film material 2 is multilayered, as can be seen, for example, from FIG. 3, and has a first layer 11 facing the pocket interior 10 and a second, outside layer 12 . In the illustrated embodiment, a third layer 13 is also hen hen, which is arranged between the first layer 11 and the second layer 12 . The individual layers 11 , 12 , 13 of the film material 2 are arranged and connected to one another in such a way that air cushions 14 , 15 are located between the individual layers 11 , 12 , 13 . The first layer 11 in the present case consists of HDPE (high density polyethylene), while the second layer 12 consists of a PE vapor-coated with aluminum. The third, middle layer 13 consists of a foamed PE.

As can be seen in particular from FIGS. 4, 5 and 8, the closure region 4 has at least one pressure closure 16 which extends over the entire width B of the carrier bag 1 . In Fig. 8, two pressure locks 16 are shown, namely an upper and a lower pressure seal 16. Although it is fundamentally possible to provide two pressure locks 16 , it is preferred and sufficient to use only one pressure lock 16 . The chosen representation of two pressure closures 16 serves only to show to the point at which one can Druckver are circuit-16th

In this context, it should be pointed out that preferably only the upper pressure lock 16 is used, since this is more easily accessible than the lower pressure lock 16 and otherwise when engaging in the individual Grifföffnun conditions of the grip area 5 held and enclosed by the hand of the user is what noticeably strengthens the grip area 5 and leads to the fact that the pressure closure 16 does not open easily.

The two pressure closures 16 shown in FIG. 8 are identical. Therefore, only one of the pressure locks 16 is discussed in more detail below. The snap fastener 16 has a provided on one side in the pocket interior 10 of the carrier bag 1 first closure member 17 and on the opposite side in the pocket interior 10 of the carrier bag 1 provided second Ver closure member 18 . The first closure part 17 has two elastic legs 19 , 20 which delimit a groove 21 which in the present case is designed like a hammer head. The second closure part 18 has a leg 22 which can be pressed into the groove 21 and which is designed like a hammer head in accordance with the design of the groove 21 . It therefore has undercuts which are engaged behind by mutually facing projections of the legs 19 , 20 . In order to achieve a certain sealing effect and stability, the two closure parts 17 , 18 consist of an elastic but somewhat stiffer plastic, which nevertheless allows the carrier bag 1 to be folded in the area of the pressure closure 16 as well.

An alternative embodiment is shown in FIG . Here, the closure area 4 has an adhesive closure 40 which extends over the entire width B of the carrying bag 1 . The adhesive closure 40 consists in the present case of an adhesive strip which, in the closed state, is located between the envelope 9 and the outside of the pocket region 3 which is turned. The adhesive strip is a strip that is provided with an adhesive layer on both sides. A protective layer, in particular made of silicone, is applied to one of these adhesive layers and is removable. The other adhesive layer is glued to the appropriate location on the carrying bag 1 accordingly. If the carrier bag 1 are closed by the adhesive seal 40 , the protective layer is removed and the traga cal can be closed after the envelope 9 is closed by the adhesive seal 40 . In this connection, it is preferred that the adhesive layers of the adhesive strip stick to different degrees. While the adhesive strip on the side where it is originally glued should adhere permanently, the adhesive connection for opening the carrying case 1 or turning over the envelope 9 should be easily detachable. In addition, the easily removable adhesive layer should also be reusable. This requires an appropriate composition of the adhesive.

It is also important in the case of the carrying bag 1 that the handle area 5 in the upper area of the bag area 3 has a first and a second handle opening 23 , 24 on opposite sides and a third handle opening 25 in the envelope 9 . It is also important that the first, second and third handle openings 23 , 24 , 25 are arranged and formed in the film material 2 such that they are aligned with one another in the closed state of the carrying bag 1 , as shown in FIG. 2, so that there is a through-handle opening. Ultimately, the grip area 5 is formed from the upper section of the pocket area 3 and from part of the envelope 9 .

As can be seen in particular from FIGS. 6, 8 and 9, the film material 2 has two layers on the side of the pocket region 3 opposite the envelope 9 in the region of the second handle opening 24 . For this purpose, the film material 2 has a further envelope 26 which is provided with a fourth grip opening 27 which is aligned with the rest of the grip openings. In contrast to the envelope 9 , the further envelope 26 cannot be handled as required. The further order 26 is turned over into the pocket interior 10 of the pocket region 3 , so that the first two layers 11 lie one on top of the other and are welded over a transverse weld 28 extending over the entire width B.

Furthermore, the film material 2 also has two layers in the region of the handle opening 25 of the envelope 9 . For this purpose, the envelope 9 itself is provided with a wide envelope 29 at its free end. In the further envelope 29 there is a fifth handle opening 30 . This further envelope 29 , like the further envelope 26, is welded by means of a transverse weld 31 , the additional envelope 29 also being folded over here in such a way that the first layers 11 lie one on top of the other. The Quererstrec tion of the transverse welds 28 , 31 is shown in Fig. 4, it should be noted that the upper part of the pocket area 3 is only folded away to show the arrangement and design of the pressure lock 16 in more detail. In fact, the upper part of the pocket area 3 cannot be folded away in the manner shown. The longitudinal weld 8 extends beyond the pressure lock 16 .

The carrier bag 1 shown in FIGS . 1 and 2 is produced from a one-piece blank 32 , as shown in FIG. 9. After the three-layer film material 2 has been produced , that is to say after the first, second and third layers 11 , 12 , 13 consisting of different materials have been brought together, the blank 32 is cut from the film material 2 . The longitudinal edges 6 , 7 and possibly also the outer transverse edges 33 , 34 can now be welded or at a later time.

The structure of the blank 32 is seen from below with reference to FIG. 10 as follows. One side 35 of the pocket area 3 connects to the further envelope 26 and to this the other side 36 of the pocket area 3 . The envelope 9 adjoins the side 36 of the pocket area 3 and the further envelope 29 adjoins this. The five handle openings are indicated by dashed lines, namely the fourth handle opening 27 in the white envelope 26 and the second handle opening 24 adjacent to this in page 35 . The next handle opening, namely the first handle opening 23 , is provided in the side 36 of the pocket area 3 . The third grip opening 25 and the fifth grip opening 30 adjoin this.

After the blank 32 has been produced , the carrying bag 1 is produced in such a way that the further envelope 26 is turned over to the side 35 around the line 37 and cross-welded. In addition, the further envelope 29 is wrapped around the line 38 and also cross-welded. Then the side 35 is folded over the line 39 so that the two sides 35 , 36 lie one on top of the other. Pages 35 and 36 are then welded lengthways to produce the pocket area. Then the envelope 9 is turned over to page 35 and the through-handle opening is punched out. The carrier bag 1 (without snap fastener 16 ) is then finished.
