Description

The invention relates to an envelope or the like with a folding clasp and opening tongue. It consists in the fact that two un-. equally long flaps are hinged, of which one at least two, the others at least three superimposed axles Have bending, punching or folding lines and are thus divided into areas, in which uppermost of the flaps serving for the closure an opener is punched out or punched out, the when folding the flaps into one another and placing them in the envelope or the like by doing the opposite Wrinkles protruding outward that the two hinged unequal closure flaps have several superimposed foldable surfaces, but the opener ' from the second step surface of a closure flap aus.- or punched, after Folding the surfaces into one another is also folded in opposite directions, so that it follows the lock protrudes outward that further provided with the graduation uniform divisions two locking flaps of unequal length on the walls of the hull o ·. like articulated lower step surfaces are provided with dry adhesive and that on the .eine with dry adhesive provided step surface a tongue cutout is hinged, which on both sides. has elongated perforated or dashed lines.

The subject matter of the invention is designed as follows.

The two unequal hinged flaps (Fig. I, 2 and 3) are each divided into several foldable step areas. In the case of the closure flap divided in this way 1, the two lower step surfaces are placed inwards as a fold and can be glued in place so that the remaining step surface is in a flap survives. As a result, the second closure flap then appears around a foldable one Step surface higher, while this was previously reversed. These two so classified Shutters are then turned over to one side as usual, see above that the shorter remaining flap is covered by the now longer flap. Should he Closure are effected, the longer flap is lifted up and the contents pushed in, then the shorter flap also lifted up; here is the

closing flap serving flap one step higher. This latter step is placed around the step of the now shorter flap and both together in the already .; Fastened or loose fold formed - flap inserted. Through the interlocking.eär ·; grab the step surfaces and "the two, closing flaps in connection with the formed inner fold of the flap and the, ίο both surfaces of the envelopes or the like. Even automatic opening is excluded, and no foreign letters, cards or the like can be in the The two outer surfaces of the envelopes or the like are completely flat, since the closure is effected in the inner part of the envelopes or the like. These envelopes or the like thus closed are opened by opening - or punching an opener into the top step surface of the flap serving as a closing flap. When the step of this flap is folded around the step of the second flap, this punched opener tongue is folded in the opposite direction. As a result, the opener protrudes outward when the envelope or the like is closed. If you then pull this tongue, the lock opens completely automatically and the contents can be removed. "
This type of closure can also be improved as desired by several interfolded step surfaces. Likewise, the two closing flaps can be provided with reinforcement strips along the inside, possibly high in one or more narrow reinforcement strips made of metal, cardboard, linen or the like, and turned over with this reinforcement for envelopes or the like with a heavy content an automatic opening or falling out of the contents of the closed envelopes or the like is excluded. When enveloping with cardboard walls or packs made of cardboard, cardboard or the like. These divided step surfaces can be directly articulated as an extension of the cardboard wall o. The hinged closure part can also be made of a different material than the envelopes themselves and glued on for this purpose. With this type of production, the attachment of the opener is not done in the top step, but always in the second step. Closing takes place exactly as in the previously described embodiment. It is only necessary to ensure that the opener is folded in the opposite direction when it is closed. This brings the opener to the closed envelope or the like. despite several folds, simply pulling on this opener causes the closure to unfold.

Should such envelopes or the like now be used. Dry adhesive closure can be produced

This is done in the following way: lowest step strips of the two

The outer flaps are provided with dry glue. After forming the envelopes o. The like. The two stepped surfaces of the flap are placed inwards, se that the dry adhesive application comes to lie inside and protrudes over the step surface, which is then turned over. The second door Serving as a closure flap, the dry adhesive is applied to the step strip and is covered or not covered depending on the dry adhesive applied should be, after one or the other side of the envelope o. If the envelope is to be closed, the stepped surface of one of the flaps becomes placed on the step surface of the other flap and folded inwards. Through this the dry adhesive application of the stepped surfaces of the two flaps comes into contact with one another Cover. The application of dry adhesive can be simplicity in this embodiment sake also done in one strip and formed by punching in two opposing strips will. In order to now also provide this type of envelope with an opener, so that the contents cannot be damaged by tearing off the outer walls of the closed envelopes or the like a tongue is also punched out on the flap. The envelope or the like is how already stated above, closed, only here it must be ensured that the Opening tongue against the stepped surface of the closure flap, which is provided with dry adhesive application is placed. After the closure, this opening tongue will then protrude somewhat from the envelope. At the Place where this opening tongue comes to rest when the envelope is closed the two dry adhesives do not streak. Hole or dashed lines are arranged to the left and right of the opening tongue, so that when opening the tongue with the part delimited by the weaknesses after the closure flaps have been pulled out to be demolished.
