Description

The invention relates to an envelope with a viewing window.

Envelopes with a window are used to send letters on which the sender's address is provided in a predetermined field on the first page. Only the stamp is stuck on the envelope itself or a franking stamp is printed. Because the envelopes are usually opened on one long side with a letter opener, they are practically impossible to reuse, since the opened long side cannot be closed again and

Sealing them with an adhesive strip seals them so tightly that they cannot be opened without additional effort. The entire material of the envelope is therefore thrown away after one use.

On the other hand, by using a viewing window, a mixed material is present, which makes recycling as waste paper more difficult.

Another problem with existing envelopes is that letter openers that are inserted behind the closure flap on the side often reach into the folded document inside, so that the letter opener also cuts through the document when the letter is opened. This is extremely undesirable.

The invention aims to avoid these disadvantages of the prior art and to create an envelope that is reusable, while at the same time protecting the document as well as possible even when opened.

According to the invention, this is achieved by the features of the main claim. It is particularly advantageous to provide a paper strip along the top of the envelope front, which is connected to an upper flap that is connected to the back of the envelope and further to the front of the envelope above the viewing window, for receiving the postage stamp or a franking imprint that closes the envelope and is completely severed for opening.

The remaining envelope of the letter can be resealed by applying another, new, separately manufactured strip. The envelope can also be provided with an adhesive strip during manufacture, which is applied to a reinforced adhesive strip on the front, or attached next to a perforation that allows the original strip to be separated from the front of the envelope.

Both the original and the subsequent strip are advantageously attached to a 1 cm wide, swing-out tab on the top edge of the envelope, which is connected to the back of the envelope.

It is also proposed to create a marked and reinforced, non-glued area on the left side (at least for right-handed people) to make it easier to grip the first strip; however, a protruding area of this area could be a hindrance during transfer and lead to damage.

If necessary, this area can be reinforced, as is known from other tear-off packaging.

Finally, it is proposed that the other new self-adhesive strips be provided with an adhesive gum only on their longitudinal edges, with which they are applied lengthwise to the envelope body that remains after the first opening. On the narrow sides, additional adhesive can be provided either on the strip or on the envelope body.

The invention further proposes to market separate strips for resealing such envelopes separately. In an extreme case, these can be offered as large sheets, like very wide stamps, for example, but they are usually provided as simple white paper strips for sticking onto existing, reusable, reinforced adhesive strips on the envelope body. They differ from stickers in that they do not have a fully adhesive backing.

In a preferred embodiment of the strips, the lower reinforced adhesive strip above the viewing window can initially be covered with a protective film, which is only used when a further strip is stuck on a second time. If necessary, strips can then be used for closure which, like the previously known backs of adhesive images, have a particularly smooth, plastic-like surface in order to enable multiple sticking with different adhesive strips. Each adhesive strip can only be used once.

The frequent use of an envelope in this way makes it economically possible to use other materials as envelopes, which can protect a letter even better than the previous disposable envelopes. It is conceivable to provide a wide variety of formats, for example shipping boxes for individual diskettes or computer disks (CDs) and the like.

Further features and advantages of the invention will become apparent from the following description of a preferred embodiment.

example using the attached drawing. It shows:

the only figure shows an envelope according to the invention in a schematic representation.

In the figure, the envelope is shown from its front with the viewing window 10 and the closure strip 12 according to the invention, onto which a franking or the stamp with the corresponding stamp from the post office can be applied. This strip can be torn off from the front of the envelope either, as shown, on one side from a perforated edge 18 and on the other side from an adhesive surface on the flap 14 or, if it is a strip applied later, from the adhesive surface 14 and the adhesive surface 20.

Unlike what is shown in the figure, the strip according to the invention protrudes beyond the tab 14 in its closed state and covers it. For easier opening, a further non-glued tab 16 can be provided on the narrow side of the strip 12 for gripping. This can also be made stronger than the rest of the strip 12.

As shown in the drawing, if desired, the reusable envelope can also be initially sealed with a separate strip and, if the gum of this separate strip can be detached from the front of the envelope in the area of the area 20, only then sealed with the strip 12 attached to the perforation as standard. This requires

then assume that later closure strips will again have adhesive on their underside.

Compared to a conventional letter, the advantage when opening it is that no tools are required, but rather a closure strip can be opened by grasping a tab 16 on the left side (for right-handed people - another tab for left-handed people on the right side is easily conceivable).

The document can then be removed from the envelope by opening the flap 14. The envelope is now ideally completely blank, so that it can be reused if only a small sealing strip is reused. Compared to the paper consumption of envelopes that are thrown away, this results in a paper saving of at least 75 to 80%. It is also easily possible to produce more complex envelopes for multiple use. These can, for example, be provided with decorative prints on the outside or the like.

Claims (8)

BOEHMERT & BOEHMERT PROTECTION CLAIMS 1. Envelope with window (10),
