WO1998013210A1 - Form with integrated card and substrate and multilayer material for producing such a form - Google Patents

Abstract

This invention concerns a form which has an integrated card which can be separated from it. Parts (K1, K2) which overlay and adhere to each other in the card are arranged, in part, in the opposite order in the form. By turning in place and/or by laying one on the other in solely one direction, they can however still be glued to one another. At least one of the two card surfaces can be written on in the form. The writing on the completed card is covered by another layer and thereby optionally sealed. To produce the form, it suffices to apply a preassembled multilayer material to one side of a sheet form and to carry out at least one stamping (S1, S2) in the area of this material. However, the preassembled material can also already include the material of the sheet form. The cards of the invention can be punched completely, i.e. without residual parts, from the form and are, insofar, simple to separate.

Description

 DESCRIPTION

TITLE form with integrated card as well as carrier and multilayer material for the production of such a form

TECHNICAL AREA

The present invention relates to a form with an integrated, removable card according to the preamble of claim 1. Cards of this type are usually referred to as butterfly cards because of the need to fold up and glue together their several parts when they are removed.

The invention further relates to carrier and multilayer materials for such forms.

Forms with a removable card are increasingly used by organizations today to collect contributions and at the same time to send a membership or ID card to the addressee. A variety of other possible uses are conceivable. Some possible uses are also mentioned in the context of this description.

STATE OF THE ART

Forms of the aforementioned type are already known in various designs and are available on the market. The well-known However, guides still have certain disadvantages, which on the one hand make it more difficult to remove the cards and / or give the finished card an unsightly appearance. In a known embodiment, for example, punch webs are left in the stamping. These have a disruptive effect on the detached card, both optically and in tactile terms, and form problem areas where there is a risk of the card tearing when it is removed. After removing the card, a hole remains in the form. The entire handling is not very user-friendly.

PRESENTATION OF THE INVENTION

The object of the invention is to provide a form with a removable card of the type mentioned, which avoids the aforementioned disadvantages. In particular, the handling should be simple and obvious, should not be necessary punch bars, the card should be easy to remove, but should be kept safely in the form level until it is removed. The invention is also intended to provide suitable multilayer materials for the production of such a form.

The solution to this problem in the case of a form of the type mentioned at the outset according to claim 1 is that the layer structure in the region of the carrier material is uniform, that the carrier material comprises a glue layer and a carrier layer from the form, so that the carrier material in the region of the glue layer is separable is that the front part is released in a non-tacky manner on the back, that the at least one die-cut is carried out from the front of the form, at least in sections, but also to a maximum of the glue layer, and that the parts mentioned are turned in place by at least one part or can be glued together in only one direction by folding them together. Preferred embodiments of forms according to the invention are given in claims 2-9. Claim 10 relates to a carrier material and Claim 11 to a fully integrated multilayer material for the production of the forms according to Claims 1-9.

Exemplary embodiments of the invention are described below with reference to the accompanying drawings.

WAY OF CARRYING OUT THE INVENTION

Reference is first made to Figures la) and 2a). There 1 denotes a form sheet. This consists e.g. made of paper, on which any information, a pattern or the like can be printed.

With 2 a multi-layer carrier material is designated. It comprises a backing layer 21, a glue layer 22, a cover layer 23, a first permanent pressure-sensitive adhesive layer 24, a first release layer 25, a base layer 26, a second release layer 27 and a second permanent pressure-sensitive adhesive layer 28. The base material 2 is by means of the second pressure-sensitive layer 28 glued to the back of the form, covering two areas B1 and B2. The two areas B1 and B2 adjoin one another at an (imaginary) boundary line G.

From the front of the form sheet 1 within the two areas B1 and B2 are mirror-symmetrical to and (not necessary) adjacent to the boundary line G, web-free punchings S1 and S2. The punching S1 only passes through the form sheet 1 and the permanent pressure-sensitive adhesive layer 28 in the area B1. The punching B2, however, extends down to the glue layer 22 in the area B2. Along the boundary line G, all layers are punched completely through a punch S3 and within the area enclosed by the punchings S1 and S2 without a web and outside this area as perforation while leaving punch webs. The punchings S1 to S3 result in the following diecuts integrated in the form:

• In the area B1 a map part Kl with two halves Kll and K21 and layers 1 and 28;

• in area B2 an additional card A with halves All and A12 and layers 1 and 25-28; and

• In the area B2, a map part K2 with the halves K21 and K22 and the layers 23 and 24.

The removal of these parts or cards from the form is explained below with reference to the sequence of figures in FIG. 2. It is important for the sequence explained that the adhesion between the first permanent pressure-sensitive adhesive layer 24 and the first separating layer 25 in the carrier material 2 according to FIG. 1 is set weaker than between the second permanent pressure-sensitive adhesive layer 28 and the second separating layer 27.

First, according to FIG. 2b), the additional card A is detached from the area B2. The separation takes place here because of the aforementioned differentiation of the adhesive values between the first separating layer 25 and the first permanent adhesive layer 24. The permanent adhesive layer 24 is the uppermost layer of the card part K2 exposed. Next, the form is folded along the boundary line G and the two areas B1 and B2 are aligned, which is facilitated by the punch S3. Here, sticks the form material 1 of the card part K1 with the pressure-sensitive adhesive layer 24 of the second card part K2. When the form is unfolded, the layers 28 and 27 separate in the area B1 and the card part K1 remains in the area B2 on the card part K2. This transfer of the car part Kl is shown schematically in Fig. 2c). The fact that during the unfolding the separation takes place between the layers 27 and 28 that are more strongly adhering to one another and not between the layers 24 and 25 that are more weakly adhering to one another is due to the smaller punching depth in the region B1.

After the transfer of the card part K 1, this is exposed in the area B2 with its rear, sticky surface (pressure-sensitive adhesive layer 28). This is shown in Fig. 2 d). By folding the form further along a fold line L parallel to the boundary line G in the area B2, the two halves K1 and K12 of the card part K1 and of course also the halves K21 and K22 of the card part K2 glued to them are brought to cover and by means of the adhesive layer 28 glued together, as shown schematically in FIG. 2e). This creates the desired card K, which can be completely detached from the form when or after the form is refolded, as shown in FIG. 2f). When the card K is removed, the cover layer 23 separates from the glue layer 22, which remains on the carrier layer 21. The cover layer 23 forms the double-sided surface layer of the card K. A perforation can also be punched in along the fold line L, at least outside the card area, as a folding aid.

A plastic film, for example a polyethylene film, is preferably used as the material for the cover layer 23. The card K is then plasticized on both sides and waterproof. If a transparent film is used, the imprint or lettering of the surface of the card part below is Kl or its two halves Kll and K12 recognizable. This surface is on the form before the card K is removed and can therefore be individually labeled. One can also say that the card K can be labeled on both sides. After removing the card, the label is sealed under the top layer.

The glue of the glue layer 22 is preferably a so-called peel glue, which can be removed easily and without residue from the cover layer 23, but nevertheless holds the card K or its parts sufficiently firmly in the form. It is preferably further adjusted so that it is no longer (essentially) sticky after the card has been removed.

The glue layer 22 could also be designed such that it adheres to the cover layer 23, goes along with it when the card is removed and detaches from the carrier layer 21. In this case, it is in any case necessary that the glue layer 22 no longer (essentially) sticks after the card has been removed. In this case, the glue layer 22 is preferably further designed such that it can be labeled on the card that has been removed. In combination with a polyester film for the cover layer 23, these properties can be e.g. with a shell with the following composition in% by weight:

70-90%, preferably 77%, of a mixture of an ethylene-containing copolymer, a copolymeric ethyl acetate dispersion, an acrylic resin copolymer and a polyvinyl acetate polymer;

3-5%, preferably 4%, aliphatic polyester urethane acrylate;

1.5-2.5%, preferably 2%, 2-acrylic acid, 2- (((butylamino) carbonyl) oxy) ethyl ester; • 12-18%, preferably 15%, modified anionic pure acrylate copolymer emulsion;

0.5-1.5%, preferably 1%, wetting agent; and

0.5-1.5%, preferably 1%, aliphatic polyfunctional isocyanurate.

The different adhesive values of the peeling glue on the cover layer 23 on the one hand and the carrier layer 21 on the other hand can be achieved by different pretreatment of the adjacent surfaces of these layers e.g. by plasma, corona or flame treatment. A differentiated adhesive effect can also be achieved using different materials. For example, a shell in the above composition adheres less strongly to a polypropylene film than to a polyester film.

After the layers 25-27 have been detached, the card A can advantageously be used as a self-adhesive label. On the other hand, by folding and gluing their two halves All and A12, another non-sticky card can be made.

Paper or plastic film can be used as the material for the carrier layer 21 and the carrier layer 26. The separating layers 25 and 27 are in particular silicone layers.

All of the punchings mentioned can be carried out simultaneously with one and the same punching tool.

The carrier material 2 can be prefabricated as a whole, preferably as continuous material, rolled up on itself and then dispensed onto the form material 1, for example in individual pieces that may be smaller than the form format. The permanent pressure-sensitive adhesive layer 28 can in this case be applied wet or already integrated in the carrier material 2. There- with this then still being able to be rolled up on itself, the backing layer 21 must be provided on the back with an additional separating coating or the pressure-sensitive adhesive layer 28 must be covered with an additional separating layer material (for example a silicone paper) that occurs as waste when dispensing.

The form according to the invention can advantageously also be produced from a prefabricated multilayer material in endless form, which in addition to the carrier material also already includes the form material 1 and in which the form and carrier material overlap over the entire surface. In this case, the actual form production is limited to punching and possibly printing, which can be carried out very efficiently in one pass through the prefabricated endless web. Cutting and dispensing of individual pieces is no longer necessary, as is any wet coating during form production. In this embodiment, the carrier layer preferably also consists of a paper material. The resulting forms have a uniform thickness over their entire area, which is of considerable advantage in their further processing, particularly in single-sheet prints.

The above statements regarding the materials and manufacturing techniques used apply in the same way to the exemplary embodiments explained below.

In the exemplary embodiment according to FIGS. 3 and 4, a multilayer material is used which, compared to the one described above, only has layers 1 and 21-25, whereas layers 26-28 are absent. The latter would not interfere functionally, but are also not required. The statements made above regarding layers 1, 21-25 continue to apply. In areas B1 and B2 on both sides of a boundary line G, two card parts Kl and K2 are punched out adjacent to and mirror-symmetrically to the boundary line G by means of a first, all-round, web-free punching line S1. The punching S1 is carried out uniformly in both areas B1 and B2 down to the depth of the glue layer 22. The map part K1 comprises the layers 1 and 23-25 and the map part K2 the layers 23 and 24. In the area B1, a further, all-round and web-free punching S2 is carried out within the punching line S1, but this extends only to the depth of the separating layer 25 . In combination with the first punching S1, the second punching S2 produces a two-part but coherent diecut A, which has the shape of a card All in the area B2 and the shape of a frame A12 in the area and the layers 1 and 25 in both areas .

To remove the card K, the diecut A mentioned is first removed, as shown in FIG. 4b). The separation takes place here between the layers 24 and 25, so that the pressure-sensitive adhesive layer 24 appears in the areas exposed by the diecut A. The form is then folded along the boundary line G, which can be facilitated by perforation along the boundary line G. In this case, the form material 1 of the car part K1 and additionally the pressure sensitive adhesive exposed on the edge of the car part Kl glues to the exposed pressure sensitive adhesive layer 24 of the second card part K2. In Fig. 4c) this is shown schematically as folding the card part K1 onto the card part K2. When the form is unfolded, the finished card K can be removed, the layers 22 and 23 separating from one another, as was also the case with the folding mentioned above. The glue layer 22 could also go along with the card K here. The embodiment of FIGS. 3 and 4 has the advantage that the form material does not reach the edge of the card. In the form, however, only the part of the card KI can be individually inscribed before the card K is removed, and thus only one side. Writeability on the other side could only be ensured by using a writable shell as described above.

The embodiment of FIGS. 5 and 6 is based on the same carrier material as that of FIGS. 3 and 4, but here a punching S3 corresponding to the punching S2 is also carried out in the area B2. The punch A thus has the shape of glasses and the card part K2 becomes identical to the card part Kl. Before detaching the spectacle-shaped diecut A, as shown in FIG. 6 d), in this embodiment the two form material layers 1 on both card parts K 1 and K 2 are detached, turned over and in each case again glued to the exposed adhesive layer 24 at the same location, as this Fig. 6b) shows. Before this, both card indexes Kl and K2 can be individually labeled with advantage. 6c) shows the turned and re-glued form layers which carry the separating layer 25 on their now visible surface.

6d) to 6f) as in the example according to FIGS. 3 and 4, the further removal and completion of the card K takes place. A difference with respect to the finished card K only results in that in the present embodiment it is no longer the whole area but is still glued to its edge.

Another example will be described below with reference to FIGS. 7 and 8, in which the card K can be used as a vignette, which can be glued behind a glass pane, for example. The card can be individually labeled in the form. will be seen, which is later visible through the glass pane. Here, too, use is made of turning a part of the card in place.

In the layer structure of the multilayer material which can be seen from FIG. 7, the previously described layers 1 and 21-24 are present again. Here, however, the glue layer 22 is preferably a permanent pressure-sensitive adhesive layer and is surrounded by two separating layers 29 and 30, the separation value for the front separating layer 30 being less than for the rear separating layer 29. A single, all-round, web-free punching S1 is carried out uniformly into the depth of the glue layer 22.

Because of the different separation values, in a first step a die-cut A comprising layers 1 and 23, 24 and 30 can first be removed while exposing the glue layer 22, as shown schematically in FIG. 8b). After turning in place, this die-cut A is reinserted into the form, its front lying on the glue surface 22 and its back provided with the separating layer 30 lying on top. This is shown in Fig. 8c). Finally, the finished card K can be removed, the separation now taking place between the layers 22 and 29, which means that the glue layer 22 goes with the card K. In contrast to the examples described above, the glue layer 22 must not lose its stickiness when detached. Through the glue layer 22, the card can be glued as a vignette behind a glass pane. One on. the original front side of the lettering (ABC) applied in the die cut A is visible through the glass pane and the glue layer 22.

In all embodiments, one or more additional punched-outs and / or cuts can be made to facilitate removal or turning over of the card (s) and their parts as a removal aid be provided by which, for example, an edge of a part to be released or turned is exposed as a handle ante or is simply exposed.

In addition, a plastic film which is provided with at least one hologram could also be used for the cover layer 23. Such films are known as hologram films. The use of such a film makes it difficult to reproduce the card and is an effective security feature.
