Description

Pattern description

The subject of a utility model is an embossed cover, especially useful as a cover for security documents, for example ID cards, registration books or passports.

The embossing technique consists in creating a three-dimensional pattern in an embossed material, for example paper, plastic or leather, by pressing with a matrix, for example to emphasize (convex embossing) or to recess (concave embossing) selected parts of the surface, creating a convex or concave character - a letter , digit or graphic symbol. Embossing is used, among others, in the covers of documents to increase their visual appeal. The construction of a multi-layer skin embossed material is known from the US patent description US5405675. The coating material consists of an embossed outer layer with a thin protective coating and an adhesive layer for adhering the coating material to the substrate.

It would be expedient to develop an alternative design of a cover with embossing, the design of which would ensure a high durability of convex characters and make it difficult to modify the embossed elements.

A utility model-embossed cover, which is a laminate of several layers, is characterized by a cover layer with embossing convex on the outside, a cover layer that is flat in the area of the cover layer embossing itself, and an adhesive layer between the cover layer and the end cover layer and filling the area. embossing.

Preferably, the cover layer has an inner layer of paper or cotton.

Preferably, the inner layer of the cover layer is covered on both sides with layers of acrylic coating.

Preferably, the cover layer has a thickness of 220 to 400 μΐη.

Preferably, the adhesive layer is a water-based adhesive.

Preferably, the adhesive layer has a minimum thickness of 5 to 40 µη.

Preferably, the end paper layer is paper.

Preferably, the end sheet layer has a thickness of 100 to 160 µΐη.

Preferably, there is an inlet between the adhesive layer and the end paper layer connected by the adhesive layer to the end paper layer.

Preferably, the inlet is of a polymer doped paper or a polymer.

Preferably, the inlet has a thickness from 280 to 400 µη.

Preferably, an integrated circuit and a coil antenna are located inside the inlet.

The presented design of the cover according to the utility model ensures high durability of the embossings, which are filled with a layer of glue, which ensures their high stiffness and protects against crushing. At the same time, since the endpaper layer is flat in the area of the embossments of the cover layer itself, this makes it difficult to falsify the cover by modifying or adding new embossings, which would disturb the flat structure of the endpaper layer.

The object of the utility model is shown in the drawing, where:

Fig. 1 shows an example of a cover with various types of markings embossed in a top view;

Fig. 2 schematically shows (not to scale) a section through the cover layers in a first pattern embodiment;

The utility model embossed cover 101 may be embossed with various types of markings (embossing) as shown in Fig. 1: Braille characters 151, graphic designations 152 or textual markings 153. These indicia may be permanent (i.e., identical for many covers). ) or personalized (that is, different for individual covers).

The embossed cover 101 in the first embodiment shown in Fig. 2 is a sandwich laminate in which the outer layers are a cover layer 110 and an end sheet 130, and the inner layer is an adhesive 120 interconnecting the outer layers 110, 130. The cover layer 110 is made of a layer. 111 made of paper or cotton covered with a layer on both sides

Claims (12)

of the acrylic coating 112, 113 and is embossed with raised indicia 115. The cover layer has a thickness (H1) from 220 to 400 µΐη. The height (h) of the convex markings 115 ranges from 60 μΐη to 120 μΐη. The cover layer 110 has an adhesive layer 120 (water-based adhesive) applied on the inside, which fills the recesses 121 in the outer layer 110 at the position of the raised markings 115. The adhesive layer 120 can be applied by means of a notched roller, resulting in an even layer of cover adhesive. 101. Filling the recesses 121 with glue 120 provides increased mechanical strength of the raised marks 115 compared to solutions in which the entire laminate is pressed. The adhesive layer 120 has a minimum thickness (that is, thickness where there is no convex markings) (H 2) of 5 to 40 μίτι. Adjacent to the other side of the adhesive layer 120 is a flat endpaper layer 130 of a paper material, for example a 120g paper. The endpaper layer 130 provides good mechanical strength and stabilizes the structure of the cover 101. The endpaper layer 130 has a thickness (H3) from 100 to 160 μίτι. End sheet 130 is flat over the embossments (115) of the outer layer itself. The embossed cover 102 in the second embodiment shown in Fig. 3 has, compared to the first embodiment shown in Fig. 2, an additional inner layer 140 made of polymer-doped paper or a polymer, called an inlet. The inlet 140 is adhered with an adhesive layer 120 on one side to the cover material 110 and on the other side with an adhesive layer 141 to the end cover layer. The inlet has a thickness of H4 from 280 to 400 μίτι and is an additional reinforcement of the cover structure with relief embossing. The embossed cover 103 in the third embodiment shown in Figs. 4 and 5 includes, compared to the second embodiment shown in Fig. 3, inside the inner layer 140 (inlet) an integrated circuit 161 and an antenna 162. Integration of the chip 161 and antenna 162 with the inner layer 140 is made by any known method. This allows the integrated circuit 161 embedded in the document cover to store various types of data, for example the data of the document holder, which can then be read over the air via the antenna 162. 1.
