Definitions

  • the invention relates to a closure for mailing bags, envelopes or the like consisting of plastic coated paper on one side. with the features of the preamble of claim 1.
  • the inspector must first consider how to activate the adhesive. If the rubber coating is a wet adhesive material, the rubber coating must first be moistened and, after gluing, a certain setting time must be taken into account before the shipment can be returned to the normal post office. If the rubber coating is a self-adhesive material covered with silicone paper strips, this cover must first be determined and removed. Both types of handling require additional considerations and additional working time or work processes. If the activation process for the second permanent bond is not carried out carefully in a hurried postal operation, there is a risk that no proper permanent closure will occur when such a checked mail item is reclosed.
  • the closure for mailing bags known from DE-A-27 06 507 avoids these disadvantages in that a single rubber coating, which is present as a self-adhesive layer, serves both for the first fixed closure and for the second fixed closure.
  • This one self-adhesive layer which is a pair of adhesives, is activated when the first fixed closure is formed; there is no activation after the postal check.
  • the invention has for its object to provide a closure of the generic type which for postage-favorable printed matter dispatches a first fixed closure that is simple and easy to open for the purpose of postal checking and, after the check has been carried out, is also simple and easy and closes safely without additional aids and / or measures second fixed closure results.
  • the invention provides an easy-to-handle mailing bag closure for bags made of coated paper, which are also in circulation as lightweight padded bags. Bags with this closure are simply constructed, can be produced on the usual mailing bag manufacturing machines without additional mechanical equipment and can be used in automatic envelope filling machines without difficulty. By post, they can be opened for testing purposes in a known, simple manner and securely closed again.
  • FIG. 1 to 5 is a plan view of the rear wall of a mailing bag formed in a conventional manner from a front wall and a rear wall 2 by edge welding on three sides of plastic-coated paper with a closure flap 3 also sitting on the front wall, the lower one Part of the mailing bag is omitted.
  • the closure flap 3 can be folded around the main fold line 4 onto the rear wall 2 of the pocket. Parallel to the upper flap edge 5 is a closed Set fold line 7 is present, and the end strip 6 between the flap edge 5 and the additional fold line 7 is double-layered.
  • the two strip parts 6a and 6b are laid with their coated surface sides against one another, so that the outer surface sides consist of uncoated paper. In FIG. 1, the viewer accordingly looks at the outer surface of the strip part 6a made of uncoated paper, and in FIG. 2 at the uncoated outer surface of the strip part 6b.
  • a rubber strip 8 is applied to the closure flap so that it partially sticks in the region 8a on this uncoated surface side of the strip part 6a and partly in region 8b adheres to the inner surface 9 of the closure flap 3, adjacent to the additional fold line 7 .
  • this rubber strip 8 consists of a self-adhesive material and is provided with a removable protective cover, such as siliconized cover paper, during storage and shipping.
  • a protective cover will advantageously also be left in place while the mailing bags are being filled, in particular when working with automatic envelope filling machines, and only when the mailing bag is filled will the adhesive material be activated. To activate it, simply remove the cover (not shown in the drawing). The closure is thus brought into the operational state shown in FIG. 1.
  • the flap 3 is simply folded over the main fold line 4 onto the pocket rear wall 2 and pressed on. Since the outer surface of the back wall 2 consists of uncoated paper, the gum 8 adheres firmly to the back wall of the mailing bag over its entire width.
  • the shipping bag securely closed in this way by means of the first fixed closure is shown in FIG. 2.
  • this first fixed closure is to be opened, for example if the shipment is to be sent as a “printed matter” and a post-side check is provided, a knife-like tool, for example a letter opener, is inserted near the flap edge 5 between the strip parts 6a and 6b of the double-layer end strip 6 and pulled horizontally along the flap edge 5 with an obliquely downward pressure.
  • the flap edge 5 can be perforated accordingly to facilitate the opening process.
  • the closure flap is returned upward about the main fold line 4 into the plane of the front wall.
  • the closure then has the shape shown in FIG. 3.
  • the separated strip part 6a of the end strip 6 adheres to the outer surface of the mailing bag rear wall 2, while the strip part 6b remains on the closure flap 3. Since the adhesive force of the adhesive material on uncoated paper is much stronger than on coated paper, when the first fixed closure is opened, the area 8b of the rubber coating 8 detaches from the coated inner surface 9 of the closure flap 3 and remains on the rear wall 2, as can be seen from Fig. 3.
  • the contents of the mailing bag are now freely accessible and can be viewed and checked at will.
  • the outer surface of the strip part 6b which consists of uncoated paper, comes to lie against the area 8b of the rubber coating 8, and then a simple pressing is sufficient to produce the second fixed closure.
  • a separate activation of the rubber coating is not necessary, since the adhesive material now comes together with the uncoated paper side of the strip part 6b, to which it can adhere firmly.
  • the second fixed closure thus formed has the appearance shown in FIG. 5.
  • Information on the type of use for example “printed matter”, “open here” or other treatment instructions can be printed on the outside of the back of the mailing bag and / or on the outside of the flap or otherwise noted.
  • a reference to the postal check carried out can be provided on the surface of the strip part 6a of the end strip 6 (after the first fixed closure has been formed). After formation of the second fixed closure, this indication then appears on the outer surface of the strip part 6a remaining on the rear wall 2.
  • the rubber coating 8 can be attached at a corresponding point on the rear wall of the mailing bag 2 and can be protected by a cover strip placed thereon until the first fixed closure is formed.
  • the cover strip is then again pulled off to activate the adhesive material, and the first fixed closure is formed by the closure flap 3 being folded over the main fold line 4 onto the rear wall 2.
  • the result is again the shape of the closure shown in FIG. 2, which can be opened and closed again as described above.
  • the closure flap has a rectangular shape corresponding to the shape of the pocket.
  • the corners of the flap edge can also be rounded, which may be advisable if the opening of the first fixed closure is to be facilitated.
