PATENT OFFICE.

The subject of the present invention forms a letterhead, which is made of one piece so it is established that a part of such an ordinary one has the address inscription on its reverse receiving letterhead with an attached cover or protective strip after the closure has been effected, an envelope-like one Forms pocket in which the sheet described is folded to lie, while a sticking to the protective strip, any decorated security flap can also be glued to the address side of the letter.

The second sheet of the sheet α is provided on the transverse sides with rubberized flaps c and on the long side with a cover or protective strip e together with a rubberized safety flap f adhering to it. The first three unbroken pages are available to the user for writing, just like a normal letterhead; the back of the second sheet remains free to be used for the address. The narrow extension of the when closing over the merged respectively. The protective strip to lie over the folded sheet also forms the aforementioned security flap, which is to be stuck to the address page, prevents unauthorized opening of the letter and offers the opportunity for decorations and the like.

Fig. 1 shows a sheet α b with the rubberized closing flaps cd and a cover or protective strip e of the same width as the sheet sides α b with safety flap f.

Fig. 2 shows this sheet folded.

Fig. 3 shows a sheet with the rubberized closure flaps and a cover or Protective strip half the width of the leaf side.

Fig. 4 shows this sheet folded.

Fig. 5 shows the address page of a letter (decorated with a clover leaf) completely closed.

Fig. 6 shows its rear side.

In the embodiment of FIGS. 1 and 2, sheet b is folded over to α , then the cover strip e is folded over; in FIGS. 3 and 4, the sheets placed one on top of the other are folded along the line k before the strip e is folded over to cover it.

In both embodiments, the two rubberized closing flaps cd then come to rest on the protective strip e to which they are glued,

The user has to do the folding himself so that the sheet can be folded while writing is not affected by the kink. Inserts can be inserted as with other letters, namely in the form of equally large, simple leaves or sheets of the usual kind.

Only the two sides of sheet b and the inner side of α are to be written on, while the outer (on the drawing the lower), invisible side of sheet α remains free and can be used to record the address, the brand and the postmark either of its entire ( Fig. Ι and 2) or half its width according to (Fig. 3 and 4) is used.

Claims (1)

At the top or protective strip e the its entire upper surface is now attached f after gummirte security flap aufsen freely in the collapsed letters to comes to rest (Fig. 2), (to the break line between α and b or in a folded sheet Fig 4) is pinched around the break line k and glued to the address side. This flap prevents unauthorized opening of the letter. If it were not present, one could be the flat or between 'the sheet α and the cover strip e. Carefully pull out the folded part of the sheet b to a corner of the left open margin of the letter, and the letter would be partly legible. Likewise, the letter could easily be returned to its original position. In addition to the safety flap, the outer edge g of the protective strip is expediently curved inwards (cut out), which makes it easier for the recipient of the letter to see where to place the knife or finger to open the letter, and which makes opening easier. When the letter is opened by cutting open the flaps c and d glued to the cover strip are cut off with it. When opening by ripping open, which is easily possible with the folded sheet (Fig. 4) because of the narrow shape of the letter without damaging it, the cover strip with the flaps will in most cases still adhere to the letterhead, but can be along the line h can be subsequently separated. In both cases, only the undamaged letter remains in the usual form, but which bears the address, brand etc. on the back and either not at all or is only folded once in its width. If one compares the properties of the new letter with the usual envelopes, it turns out that the sheet α resp. the right half of it with the cover strip hanging on it forms the actual (letter) pocket, which holds the remaining, also folded parts of the letter. In contrast to an already finished letter envelope, this pocket is only really created by the folding and closing of the letter with the aid of the closing flaps. The address side is and will remain on the letterhead. The cover strip together marks the second part of the envelope (the pocket) the closure flaps sticking to it, which falls away with them when they are opened. The actual closing flap is again marked by the safety flap f , which, however, remains glued to the address side and therefore also allows an appropriate decoration. If a monogram or the like is attached to the safety flap, it remains also received after opening the letter. You can also give this flap any other shape, e.g. a Seal, a buckle, a leaf, a flower, a bird, a ship and so on. In order to prevent the individual parts of the letter from being puffed up when it is sealed or To prevent it from being stuck shut, the leaf part b is about 1 mm narrower than α, and the edges of the cover strip converge a little towards its outer (free) side, as shown in FIG. ΡΑΪENT CLAIM: Lockable letterhead, characterized by the arrangement of a cover flap (e) with rubberized tongue ff) on a sheet (a) of the letterhead and by two rubberized flaps fed), so that the letterhead to be written on on three sides is folded away from the flap fe) covered, is closed by the rubberized flaps fed) and the rubberized tongue ff) . 1 sheet of drawings.
