Description

Envelope for shipping documents

The present invention relates to an improved envelope for past and payment forms, shipping documents and the like and a method of making it

The subject of the invention is the creation of a packing slip envelope, which can be glued on a package, which is simple and economical to manufacture, and easy on a package can be attached and opened to inspect the documents it contains; also can be found in it Easily exchange documents and the cover can then be closed again.

It goes without saying that the terms "pressure sensitive Glue "and" self-adhesive "are synonymous and refer to refer to the same adhesive or the product provided with it.

There are known envelopes that consist of a rectangular rear Sheets of polyethylene are made with a pressure-sensitive adhesive layer and a release liner on the surface that is on top of a Package is fastened with a rectangular front sheet of polyethylene, which is welded on three peripheral edges is connected to the back sheet; then they have a strip portion that goes out from there at the unsealed end edge and extends beyond the unsealed end edge of the back sheet. The peel-off liner also extends over the rear one Sheet and creates a grip edge that makes it easy to remove the

Afaziehfuttera relieved. When in use, the pulling chuck is dated back sheet removed and the strip folded over the opening of the envelope and attached to the adhesive back surface, so that this closes the envelope with the documents contained therein. The envelope is then glued onto the package. Note that there is a loose edge in the area of the strip so that it is not glued to the package, and furthermore, that it is difficult to remove the documents from the envelope for inspection as the envelope is at least partially removed from the package and the strip must be peeled off.

Packing envelopes are also known to take around their four Have rectangular sheets of polyethylene welded together around the edges. The whole surface of the back leaf, i.e. the sheet that is glued on the package is pressure sensitive Adhesive and an overlying release liner. A slot runs across the release paper and the back sheet and thus creates an opening for access to the inside of the envelope. Once the envelope is taped on the package, that is Difficult to remove to inspect the documents. There are also known similar envelopes with two welded all around their edges Polyethylene sheets with an access slot in the peel liner and in the back sheet; this back sheet is attached to the package and has a pressure sensitive adhesive layer on top of it horizontal release paper. The outside of the back sheet is not coated with glue in the area of the slot; so arise free edges of the release paper for easier removal of the lining. Such envelopes have the same disadvantages.

It is costly to manufacture and the documents are difficult to inspect and the envelope is difficult to reseal.

In the above known envelopes, the exchange is the Documents and the resealing of the envelope are not simple and not always possible, uieil the glue no longer properly sticks, uienn sr a second time on a package surface pressed on.

According to the present invention, there is an envelope for receiving postal and customs forms, shipping documents or the like made of a front and a back sheet, both made of plastic material that is heat-sealed or welded by radiation can be. In doing so, the front sheet is drawn along the edges of the sheet sealed or welded to the back sheet, thereby defining a space between the sheets for receiving a document; the back sheet has a pressure sensitive adhesive on its side remote from the front sheet and one over it horizontal peel liner when the envelope is not in use; the lining can be removed from it when the envelope is in use shall be. An insertion opening gives access to the space between the leaves; a closure flap extends from the edge next to the opening and can be pushed into it. The flap is on best shaped and big enough to be easily inserted into the opening, especially without wrinkling in the area the welding.

The flap can be formed as an integral extension of the back leaf by fitting the back leaf to one of the

709809/0408

Flap produces the corresponding strips, but not with them pressure sensitive adhesive. The front and back sheets are sealed together on all edges except one edge lying next to the flap, and the insertion opening results from the open side produced in this way. The pulling chuck can if desired, protrude freely from the back sheet and lie under the flap and thus form a support surface for this during storage. However, it is best to seal the periphery of the front sheet or welded, and the insertion opening is provided by a slot or gap in the front sheet, whereby the flap is made of the material of the front sheet and protrudes from the sealed or welded edge next to said opening.

The plastic material is predominantly a polyvinyl chloride or Polyethylene sheet, and in the latter case at least the sheets are joined by heat sealing one for a kind of deformation of the folding area of the flap, e.g. by Perforation or kinking to facilitate insertion of the flap into the slot and to allow the flap to be substantially lies flat when put in the tucked-in position is. The flap is best shaped or cut so that it can be inserted into the document insertion opening.

The envelope is best rectangular, and the flap says about one Side out; the flap is designed so that it facilitates insertion into the opening mentioned. The opening is best a straight slot parallel to the side from which the flap protrudes, although the slot is any other Can have a shape that allows for the insertion and retention of the closure flap relieved.

709809/0408

It goes without saying that the present invention is also on the mentioned envelope when the mentioned peel back paper has been removed and the envelope for the Ready for use.

Also according to the present invention comprises a method of making an envelope for receiving shipping papers or like passing a front or top strip of plastic material under a cutting device shown in FIG an edge dBs strip creates cutouts for demarcation the flap parts and cutting the said strip in the area next to the flap, whereby the strip becomes a sealing or override statian continues; the upper first strip cut in this way is transferred to a rear or lower one Strip of plastic material with a pressure sensitive adhesive and release paper on the one remote from said first strip Side applied; the method also includes sealing or Radiation welding the first and second strips; this creates a pocket with the slot in the front sheet of the envelope thus formed lies and the flap protrudes from its heat-sealed portion; then the first and second strips cut across the flow direction along the heat-sealed portions to separate the envelopes thus formed. It's clear, that when the flap is formed as an integral extension of the lower strip, the lower strip \ o η of the cutting device is trimmed in an area that is not coated with adhesive. The mentioned second trimming of the top strip is best left out, as normally an open, unsealed

709809/0408

Applicable page is left for plugging in, although this is actually also sealed and the opening can be made in the front sheet as previously indicated.

The plastic material is preferably polyethylene film and the cutting device is preferably a rotary or flat bed cutter.

Also, the pocket created by heat sealing is best rectangular and the slot is straight.

In a preferred embodiment of the present invention, a suitable Defαrmationsvorrichtung, uie a rotatable perforating device or a kinking device or the like, applied to the folding area of the closure flap, the deformation occurs, to facilitate folding and tucking the flap into the opening and laying the flap flat in the slot.

It is pointed out that the packaging envelope after the The present invention is particularly advantageous and desirable because it is simple and therefore has minimal manufacturing and material costs caused; in addition, it can easily be opened to inspect the documents and then easily closed again.

It is also considered to be within the scope of the present invention lying down, if two envelopes are produced one after the other in a manner similar to that described above; then, however, must be used for production The flap would require cutting devices on each side of the strip and possibly in between

709809/0408

make a flap; In addition to the cross section, a longitudinal cut must also be made along the central plane in order to produce the envelopes as "individual envelopes ¹¹ ".

The invention is exemplified with reference to the accompanying drawings Drawings described in more detail. In these is Fig. 1 is an exploded view of a packaging envelope,

Fig.2 is a view of the front of the envelope with cut away Share to show the construction and

Fig.3 is a schematic representation showing the strips of film and Shows parts of the cutting and perforating device.

The packaging envelope comprises a rectangular varder sheet 1 made of polyethylene, a back sheet 2, also made of polyethylene, and a release liner 3 attached to a pressure sensitive ^{adhesive coating 2 1} on the 2 "dBS surface of the back sheet 2 remote from the front sheet .

The front sheet 1 is heat sealed at k along the four peripheral side parts to the four peripheral side parts 5 of sheet 2. A flap 6 protrudes from the top edge of a heat-sealed side of sheet 1 and the like.

In sheet 1 a slot 7 is provided which runs between the heat-sealed parts. Slot 7 is made by cutting the Material from which the front sheet is formed, and the slot ends are made by joining and fusing during the Sealing of the front sheet 1 with the rear sheet 2 is limited. Slot 7 provides access to the inside of the envelope Inserting and removing documents and takes the free end from flap 6 open. Flap G is shaped so that it can be inserted

709809/0408

relieved in slot 7 and points heat-sealed on the top Edge up a number of perforations 8 to make the flap 6 easier to fold.

Only one half of the envelope production arrangement is shown in FIG shown, the other half is identical. Earth the envelopes made in two parallel rows, with the lower closed ends next to each other before the final cut « lie.

In Fig.3 a strip of polyethylene film is used for the rear Sheet 2, which has a pressure sensitive adhesive layer 2 · on the surface 2 ", which is covered by a release liner 3, from a feed roller (not shown) to a heat sealing station guided. A strip of polyethylene sheeting 1 It is fed from a feed roller (not shown) under a rotatable one Cutting device 9 with two cutting edges 10 (uiovon only one shown and) passed - one at each end - around the front film to cut, so that oils produce the flap G in the desired shape.

On the Ualzenteil of the cutting device 9 is next to each Cutting edge 1D a perforation ring 11 for making the perforations S mounted. A slitting knife 12 is behind the cutter 9 arranged, which continuously cuts the film 2 next to each flap G before it is in the heat sealing station arrives. At the (not shown, but known) heat sealing station, over-welds with transverse weld seams are made generated, which run across the longitudinal axis of film 1 and 2

7098Π9 / 0408

and the SBitBn of at least 2 opposing envelopes (only one is shown) form; a longitudinal seam is also required which forms the bottom of the envelopes. With this heat seal uiird the cut front film 1 is fused with the rear film 2 and so slot 7 on the front side of a formed every envelope.

After the heat dissipation station, the envelopes are in a familiar üleise by a guillotine 13 along the transverse seams and along cut the lower longitudinal seam and thus form the two parallel rows of individual envelopes.

The upper slide 1 is best unprinted or printed, and hjenn printed, the printing of foil 1 can be done immediately before rotatable cutting device and the perforating device happen. To make it easier to insert and remove flap 6 from slot 7, the free edge of flap S and / or Slot 7 a marking device can be connected to clearly delimit the flap; it can take the form of a printed one Line or multiple lines or other markings.

A device for easily removing the peel-off liner can also be provided, e.g. B. by making a slot in the back sheet and in the lining, which is best parallel to one edge. Optionally, the peel-off lining can extend beyond the heat-sealed edge from which the flap extends, so that the lining can be easily removed and at the same time provides a support for the flap that might otherwise be kinked during transport or storage _o The free one under the flap The protruding lining part can also be formed by peeling off a corresponding part of the rear sheet.
