Below will be a detailed description of various embodiments of the invention with reference to the drawings.

Brief Description of Drawings

FIG. 1 is a perspective view of a package according to an exemplary embodiment of the present with a lid in an open position, in which the lower edge or tab of the label is attached to the front side of the flap of the front wall of the lid;

in fig. 2 is the top of the package shown in FIG. 1, a side sectional view;

in fig. 3 is a plan view of a part of a sheet of cardboard material folded to form a container for accommodating a pack of tobacco products therein;

in fig. 4 illustrates a possible method for treating a lid front wall valve with a laser or some other non-machining device.

Implementation of the invention

FIG. 1 shows a rigid package 1 made of a cardboard material such as cardboard or thick paper, with a hinged lid 2 and a bottom part 3 containing a plurality of cigarettes 4 wrapped in a protective material 5, forming a pack 6. An opening 7 is made in the protective material 5. The opening 7 is formed when the detachable segment 8 of the protective material 5 rises, providing access to the cigarettes 4. The protective material 5 can be made of metallized plastic or a laminated material of plastic and metal foil.

Above the segment 8 there is a label 9 attached to it, on the lower surface of which, facing the protective material 5, a contact reusable adhesive is applied, the adhesive strength of which is sufficient for the label 9 to remain attached to the segment 8. Alternatively, on a portion of the lower surface of the label 9, located above the removable segment 8, can be applied with a permanent adhesive. However, in places where the label 9 extends beyond the boundaries of the removable segment 8, a reusable adhesive is applied to its lower surface.

To ensure secure adhesion, an inner frame (not shown) may be provided inside the pack 6, which partially surrounds the cigarettes 4 under the protective material 5. This inner frame provides a support frame under the protective material 5 to resist the peel force of the label 9 around the periphery of the opening 7.

The region 10 (FIG. 2) of the lower edge of the front wall of the label 9, which may include a tongue, is attached to the front wall 11 of the lid 2, so that when the lid 2 is opened, the label 9 is simultaneously pulled back, revealing the opening 7. In particular, as shown in FIG. ... 1 and 2, when the lid 2 is in the open position, the segment 8 of the protective material 5 is pulled back and opens the opening 7, allowing the consumer to easily remove the cigarette 4 from the pack 6. Although the segment 8 can be removed, it should be borne in mind that when opening hole 7, it can remain at least partially attached to the rest of the protective material 5.

As most clearly shown in FIG. 2, a portion 12 of the outer surface of the label 9 is adhered to the lid 2 with permanent glue, so that when the lid 2 is pivoted to the open position, it is folded back relative to the rest of the label 9.

When the lid 2 is rotated to the open position relative to its edge 13, the label 9, together with the removable segment 8, is pulled or pulled from the protective material 5. If the package 1 is opened for the first time, when the lid 2 is opened, the removable region 8 can also be separated from the rest of the protective material 5 along the line of weakening separating the removable region 8 from the rest of the protective material 5.

It should be noted that when the cover 2 is rotated relative to the edge 13 back to the closed position, the label 9 returns to the protective material 5, and the removable region 8 of the protective material 5 rests in its original position on the opening 7. The peel-off adhesive coating of the peripheral region 14 of the label 9 adheres again to the protective material 4 surrounding the opening 7, resealing the package 1.

The lid 2 comprises a front wall 14 and a flap 15, which folds almost 180 ° relative to the front wall 14 along the fold line F between the front wall 14 of the lid and the flap 15, so that the rear side 16 of the flap 15 rests against the inner side 17 of the front wall 14 of the lid, and the front side 18 of the valve 15 remains open.

The rear side 16 of the flap 15 can be permanently adhered to the inner surface 17 of the front wall 14 of the lid. Folding the flap 15 of the front wall of the lid along the fold line F allows printing on the outer surface 19 of the front wall 14 of the flap and further, beyond the fold line F, on the front side 18 of the flap 15. The outer surface of the label 9 is adhered to the front side 18 of the flap 15.

The paperboard material from which the lid and bottom are made may comprise a metallized or otherwise coated outer surface layer. This surface is external, visible to the consumer. For example, the board material can be "Transmet" board, which is a filmless metallized board that provides a shiny metallized coating that can be printed. Transmet cardboard is produced by API Group. Alternatively, Metpol cardboard containing a metallized layer covered with a polymer layer can be used as a material.

It is understood that when the flap 15 of the front wall of the lid is folded back along the fold line F, the front side 18 of the flap 15, to which the label 9 is adhered, is a metallized or otherwise coated surface. This surface has a low absorption capacity and has a low penetration capacity of the adhesive, so that the adhesive cannot penetrate sufficiently to form a secure bond. This problem is common for both Transmet and Metpol, as the outer surface layer of these types of board is not porous and does not absorb adhesive well.

According to the invention, the front side 18 of the flap 15 is non-machined to increase its glue absorption capacity, thereby improving the adhesion between the flap 15 and the label 9.

As a result of the non-mechanical treatment of the valve 15, all or part of the surface layer or coating is removed and the underlying cardboard is exposed, which has a much higher ability to absorb glue. Thus, the label 9 is adhered to the treated surface. It should be noted that the entire front side of the lid front wall flap may be non-machined. Alternatively, non-machining can only be performed on a portion of this surface.

The specified processing can be carried out using a laser, for example, carbon dioxide. The laser 20 can have a rated power of 100 watts and operate in the range of 50 to 90% of its power to remove the surface layer or coating, with little or no damage to the underlying cardboard. The method for using the laser is shown in FIG. 4, a laser processing unit 20 is shown emitting a laser beam L onto the front side 18 of the cover front wall valve 15. If necessary, the laser can be moved. For example, the laser unit 20 may move in the directions shown by arrows X and Y in FIG. 4. Alternatively, the laser processing unit 20 can remain stationary and the lid front wall flap 15 can move underneath. The laser processing unit 20 may remain in an active state for a short period of time sufficient to treat the valve 15. For example, the laser processing unit 20 may operate for a period of time on the order of 0.5 seconds.

Alternatively, a chemical or plasma treatment may be used to remove a portion of the skin layer from the lid front wall flap 15.

It should be noted that, as shown in FIG. 4, the processing is carried out after folding the flap 15 of the front wall of the lid with the folding unit 21 and pressing it against the inner surface 17 of the front wall 14 of the lid, and before applying the glue in the gluing unit 22, which applies the glue to the treated front side 18 of the flap 15 and presses the label 9 against front side 18. However, it should be borne in mind that the specified processing can be performed at any other time or at any other stage of the production or packaging process. For example, non-machining may be performed prior to folding the valve 15.

It should also be noted that the aforementioned treatment can be applied to both the entire lid front wall flap 15 and only a part of it. Treatment of the valve 15 of the front wall of the lid can be carried out in such a way that it removes the entire surface layer or coating, or only part of the surface layer or coating.

Preferably, the processing is performed in the packaging machine during assembly of the package after folding the lid front wall flap 15 with the folding block 21 and pressing it against the inner surface 17 of the lid front wall 14, but before any other bending of the paperboard material. The folding of the valve 15 and its pressing against the inner surface 17 of the front wall 14 of the lid is illustrated by means of FIG. 3, which shows the lid front wall flap 15 during folding along a fold line F along the lower edge of the lid front wall 14 in the direction of arrow A.

While the present invention primarily involves removing the surface layer or coating from the board material, it will be appreciated that it can also be used to treat board that does not contain the surface layer or coating to remove any degraded material or oxides and open up a "fresh" a surface that is better at absorbing glue and provides a higher quality of adhesion.

The label 9 containing the portion attached to the front side 18 of the lid front wall flap 15 may be in the form of a detachable member attached to the wrapped bundle 6. Alternatively, however, a laminate may be used as the protective material 5. In this case, the label 9 can be made in the form of an element that is separated from the protective material 5, and can contain one or more layers of a laminated material.
