Friedel Knittel, Eichsfelder Str. 47, 3000 Hannover 21 "Mailing bag especially padded mailing bag"

The invention relates to a mailer _3, in particular a padded mailer j made of paper coated on one side with a weldable plastic, with a closure flap coated on its inside, foldable onto the rear wall and fixable on the rear wall by an adhesive strip.

There are padded, closable mailing bags made of paper with a closure flap, in which to form one that can be opened multiple times or a permanent fastener on the inside of the flap or on the Mailer bottom gummings are provided in such a way that when the gumming is moistened the permanent and when pressing the closure flap is created without moistening the dry adhesive closure (DE-AS 22 54 335). The dry adhesive seal can consist of two co-operating adhesive bonds exist or also from a double

layered adhesive tape in the form of a self-adhesive tape, which is either on the bottom of the bag or on the inside of the closure flap is attached, while the fixed closure is provided in the form of a wet rubber coating which is reactivated by wetting.

The aforementioned form of training only relates to padded mailing bags, which are made of uncoated paper, in which the order and the adhesiveness of the mentioned Dry and wet adhesive coatings pose no problems.

In the case of mailing bags of the type mentioned in the introduction, made of a plastic that can be welded or sealed on one side coated paper and a foldable closure flap coated on the inside, it has become known to attach a double-coated adhesive tape to the coated inside of the flap with an aggressive adhesive and to equip it with a removable cover, for example siliconized paper, which after filling peeled off the mailer immediately before closing the flap. The glue is like this aggressive that it adheres itself to the adhesive-repellent, internally coated side of the closure flap. When the closure flap is pressed onto the back wall of the bag, a very durable fastener is thus formed because the aggressive glue with the uncoated paper

forms an even stronger connection than with the coated side of the closure flap.

If such mailers are to be used for shipments that must be able to close the closure to open the shipment to check the shipment and then to close the shipment again, this helped that a second, but one-sided coated adhesive tape has been applied to the back wall of the bag, which with the adhesive-coated side attached to the back wall of the bag, while the side facing outwards Side of the tape is so strongly adhesive-repellent that when you press the aggressive adhesive strip to seal it the mailer only had a low adhesive capacity and thus the possibility of the closure flap was opened up to open and close again several times, without the aggressive adhesive on the interacting with it second tape stuck.

The known bags of the aforementioned type are accordingly either only with a fixed lock or with a multiple designed to be opened closure and can accordingly only be used for one or the other type of shipment. In addition, in the known bags, the double-sided coated adhesive strip with the aggressive adhesive causes relatively high costs, which in the production of bags with a multiple opening

can be increased by the fact that on the back wall of the bag the said counterstrip with the adhesive repellent Coating is necessary. The known bags have the further disadvantage that they are trained with a multiple The opening of the closure makes it more difficult to remove the shipment for checking and to refill the bag, that the contents of the bag with the aggressive adhesive strips when removed or reinserted in the bag can come into contact on the inside of the flap.

It is the object of the present invention to design a mailer in such a way that the disadvantages described above are avoided and a mailer can be made with much less effort, both for one and for the other type of shipment can be used and thus only a pocket design for the storage of different shipments

is required.

The mailer is labeled to solve the above task in that the closure flap is used to form an optionally multiple opening or a permanent fixed closure at its free end with one of the width of the adhesive strip corresponding to a fold or perforation line inwardly foldable and / or separable strip is equipped, and that on the back of the bag

directly to the foldable or detachable strips of the folded flap then arranged the adhesive strips is j which with the coated flap side a separable adhesive and with the folded strip one Plague lock forms.

With the new design of the mailer there is only one adhesive strip required, which has such an adhesive rubber coating that it connects to the coated side of the closure flap forms the multiple-opening adhesive seal, with the one on the inside of the closure flap provided coating as an adhesive-repellent layer comes into effect, while the same adhesive strip with the folded-over end strip of the closure flap thereby forms the fixed closure in that this folded-over strip is uncoated is and thus forms a permanent adhesive seal by pressing on the adhesive strip.

During the manufacture of the multiple-opening closure, the one provided at the free end of the closure flap forms foldable strip in its folded position a good one Handle to grasp the closure flap when the bag is to be opened to check the contents. For this reason, it is useful when arranging a perforation line, the perforation openings in larger ones To arrange distance. In the event that the protruding free

If the end strip of the closure flap should be a hindrance in the production of a multiple-opening closure, the end strip can easily be separated from the closure flap, since the multiple-opening closure can be opened in the usual way by appropriate shaping of the rubber coating, even without the protruding edge can be reclosed. So it is up to you to either leave the protruding strip on the bag as an opening aid or to separate it if the bag is to be shipped with a multiple-opening closure. During the manufacture of the fixed closure, the free end strip of the closure flap is folded over onto the inside of the flap and the closure flap is then pressed onto the rear wall so that the folded-over strip forms the fixed closure with the rubber coating. Such closed bags can be opened by the recipient much more easily than is previously the case with such bags with a fixed closure, since he only has to use a letter opener or the like then to be able to move into the open position.

In a further expedient embodiment it is provided that the adhesive strip arranged on the back wall of the bag consists of a double-coated adhesive tape.

Finally, deviating from the aforementioned embodiments it can also be provided that on the back of the foldable and / or detachable strip of the closure flap and a rubber adhesive strip is arranged on the back wall of the bag. The one provided on the back wall of the bag Adhasionsgummierungsträger must be in terms of his Adhesive strength be designed so that it forms the reopenable adhesive seal with the coated side of the closure flap, while it interacts with the folded over one Strips of the closure flap and the rubber coating provided on it forms the fixed closure.

In the embodiment of FIG. 1, the closure flap 5 is shown in dashed lines in the open position in which the pocket is filled. The closure flap is shown in the closed position in solid lines, namely with a bent-up corner of the flap 5, which it occupies at the beginning of the opening movement of the closure .

The adhesive strip 8 of the training according to Fig.l acts in the closed position of the flap 5 with the coated inside of the flap together, so that as a result of the adhesive Repellent properties of the inner coating of the flap result in an adhesive seal that can be opened several times. the Flap 5 can thus be grasped by grasping a corner of the flap 5 by bending it up and pulling it off the rear wall 2 of the bag Move it back to the open position, for example to check the content of printed matter. Afterward the bag can be closed again, namely by the fact that the closure flap 5 is in the position shown in Fig. 1 reproduced flat sheet is pressed onto the rear wall 2 of the bag.

The detection of the closure flap 5 to open the closure is through the protruding over the adhesive strip 8 End strip 7 of the closure flap 5 is made much easier.

In the case of the bag according to FIG. 3, the closure flap 5 is in the open position in solid lines and in dashed lines Lines shown in the closed position with the formation of a multiple-opening adhesive seal.

In this example, the outside of the strip 7 is provided with an adhesive layer 9, which acts as an adhesive rubber coating is designed and only with a counter rubber strip a lock leads. The one provided on the back wall 2 of the bag The rubber coating 8 is in turn designed in such a way that it is also connected to the coated inside of the closure flap 5 forms a multiple-opening adhesive seal. If the flap 5 is folded flat and against the When the rear wall 2 of the pocket is pressed, the flap 5 assumes the position shown in broken lines in FIG. 3, i.e. the already mentioned multiple openable adhesive seal through the interaction of the adhesive strip 8 with a coated one Opposite area of the closing flap 5

■ For the preparation of a solid closure of the strip 7 is in turn passed on to the inside of the flap 5 and the flap then folded over in this position on the rear wall. 2 The adhesive strip 9 located on the outside of the flap then coincides with the adhesive strip 8, so that an extremely strong and permanent seal is thereby formed. In this aforementioned embodiment, the

Adhesive strips 8 with one compared to the training 1 and 2 are formed with a lower bond strength, so that a relatively easy, but sufficiently secure rer, multiple-opening adhesive seal when turning the flat flap 5 results.

The reproduced adhesive strips 8 are expediently as shown in Fig. 4 with a removable cover 10, which is only immediately before closing the pockets is removed in a known manner. This arrangement has the advantage that the pockets after their Completion and finishing with the adhesive strips even when packing and stacking cannot stick together and a relatively aggressive adhesive can be used can, which does not come into contact with the filling material through the cover, because first the pockets are filled and then only the cover strip 10 is peeled off.

A double-coated one can also be used as the adhesive strip 8 Self-adhesive tape can be provided.

The figures also show that even after the production of the multiple-opening adhesive seal when it is removed of the goods for checking and refilling the goods cannot come into contact with the adhesive strips and thus Difficulties in removing and refilling the pockets can be avoided.
