One portion of the adhesive label is attached to the inside surface of the cover.

In this example cigarette, the packaging material 1 described below is used to form a packaging bale by wrapping the packaging material around a group of articles, such as a group of tobacco industry products.

The wrapper comprises a laminate having a series of cut lines and a label for forming an opening in the laminate for extracting the cigarette from the package. The cutting lines and the label provide a convenient mechanism for opening the package for access to the cigarettes. In addition, the label provides an effective and durable seal that improves the shelf life and freshness of the cigarettes in the package.

As described in more detail with reference to Figures 6A and 6B, the laminate 2 has two or more layers. In this example, the laminate 2 has a first layer 3 and a second layer 4. The first layer 3 is an outer layer, and the second layer 4 is an inner layer such that when the package is wrapped around a group of cigarettes, the first layer 3 is disposed on the outer side of the package bundle, and the first layer A second layer 4 is placed on the inside of the package bundle.

The laminate 2 is provided with a first cutting line 5 in the first layer 3 and a second cutting line 6 in the second layer 4. If the cutting line is in the layer of the laminate material 2 on the illustrated side, the first and second cutting lines 5, 6 shown in the figures are shown as either solid lines, or If the cutting line is in the layer of laminate material 2 on the opposite side of the description, it is shown as a dashed line.

Further, the packaging material 1 is provided with an adhesive label 7.

For the sake of clarity, that is, the features underneath the adhesive label 7 are visible, in the figures, the adhesive label 7 is shown to be transparent.

Figure 1 shows the packaging material 1 from the side of the first layer 3 of the laminate material 2 to which the adhesive label 7 is applied. 2 shows the packaging material 1 from the side of the second layer 4 of the laminate material 2.

Referring to Figures 1 and 2, a first cutting line 5 is formed in the first layer 3 of the laminate 2. The first cutting line 5 extends through or substantially passes through the first layer 3 of the laminate material 2. The first cutting line 5 does not extend into the second layer 4 of the laminate 2.

The first cutting line 5 in the laminate 2 determines the boundary of the first region 8 of the first layer 3, as indicated in FIG. The first cutting line 5 has a bottom edge 9 opposite the side edge 10 and a partial top edge 11 extending from the opposite side edge 10. Thus, the first region 8 of the first layer 3 remains attached to the remainder of the first layer 3 of the laminate material 2 beyond the top edge 11 when the packaging material 1 is opened as described below. It is used as a shaft.

The second cutting line 6 is formed in the second layer 4 of the laminate material 2. The second cutting line 6 extends through or substantially passes through the second layer 4 of the laminate material 2. This second cutting line 6 does not extend into the first layer 3 of the laminate 2.

The second cutting line 6 in the laminate 2 determines the boundary of the second region 12 of the second layer 4, as indicated in FIG. The second cutting line 6 has a bottom edge 13 and an opposite side edge 14 which are parallel to the bottom edge 9 of the first cutting line 5 and the opposite side edge 10, and are formed by the first cutting line 5 The bottom edge 9 and the opposite side edge 10 are offset. The opposite side edges 14 of the second cutting line 6 extend to or near the partial top edge 11 of the first cutting line 5.

The second cutting line 6 is offset relative to the first cutting line 5 such that the second cutting line 6 is disposed within the first cutting line 5. Therefore, the second region 12 is smaller than the first region 8 and is disposed within the first region 8. That is, the edges 13, 14 of the second cutting line 6 are offset inwardly by the edges 9, 10, 11 of the first cutting line 5.

In this way, the first and second cutting lines 5, 6 determine the boundary of the peripheral region 15 provided between the first and second cutting lines 5, 6.

As for the first region 8 of the first layer 3 of the laminate 2, the second region 12 of the second layer 4 remains attached to the remainder of the second layer 4 of the laminate 2 across the top edge, The top edge is in line with the top edge 11 of the first cutting line 5.

As also shown in Figures 1 and 2, the adhesive label 7 is attached to the laminate 2 on the side of the first layer 3. The adhesive label 7 is attached to the first layer 3 of the laminate 2 using an adhesive. In this example, the adhesive label 7 is attached to the laminate 2 by a pressure sensitive adhesive.

The adhesive label 7 is attached to the laminate 2 such that it covers the first cutting line 5. The adhesive label 7 is larger than the first region 8 and is positioned such that the adhesive label 7 overlaps the edges 9, 10, 11 of the first cutting line 5 to form around the first cutting line 5 on all sides. An overlap region 16 in the adhesive label 7.

As shown, the adhesive label 7 includes a pull tab 17. The pull tab 17 extends from the bottom edge 18 of the adhesive label 7 adjacent the bottom edges 9, 13 of the first and second cut lines 5, 6. The pull tab 17 can be a non-adhesive or the adhesive can be neutralized so that the user can grasp the pull tab 17 for opening the wrapper 1 in the manner described below.

Figure 3 shows the packaging material 1 from the side of the first layer 3 of the laminate 2. As shown, when the pulling tab 17 is pulled, the adhesive label 7 is lifted away from the laminate 2, and the first and second regions 8, 12 of the laminate 2 are along the first And the second cutting line 5, 6 is separated from the rest of the laminate 2. In this way, the first and second regions 8, 12 of the laminate 2 are lifted away from the remainder of the laminate 2 to form the opening 19.

Where the first and second regions 8, 12 overlap, that is, within the second region 12, the first and second layers 3, 4 remain attached due to the bonding therebetween. In the peripheral region 15, between the first and second cutting lines 5, 6, the first and second layers 3, 4 of the laminate 2 are layered, i.e., separated.

Therefore, the size of the opening 19 established in the laminate 2 is defined by the second cutting line 6.

When opened, the first and second regions 8, 12 of the laminate 2 form a flap 20 of material. Along with the adhesive label 7, the flap 20 can be lifted to provide the opening 19 and can then be repositioned to close the opening 19.

In this example, a pressure sensitive adhesive is provided between the first and second layers 3, 4 of the laminate 2, and is also provided to the adhesive label 7 and the first of the laminate 2 Between layers 3. Therefore, when the adhesive label 7 is repositioned over the opening 19, the adhesive label 7 will be reattached to the laminate 2 in the overlap region 16, and the laminate material 2 is first And the second layer 3, 4 will be reattached to the peripheral region 15, where the delamination has occurred the first time it is opened.

In other examples, a single use adhesive may be provided between the first and second layers 3, 4 of the laminate 2, and/or between the adhesive label 7 and the laminate 2.

In this way, the packaging material 1 will be reattached only when closed, where a pressure sensitive adhesive is provided. Alternatively, the packaging material 1 may contain only one adhesive for use without a pressure sensitive adhesive, and thus no part of the packaging material 1 will be reattached after the first opening.

In a specific example, a single-use adhesive is provided between the first and second layers 3, 4 of the laminate 2, although a pressure-sensitive adhesive is provided to the adhesive label 7 and the laminate. Between the first layer 3 of material 2.

Therefore, the pressure sensitive adhesive in the overlap region 16 can be used in The adhesive label 7 is reattached to the laminate 2 after the first opening, but the first and second layers 3, 4 will not be reattached to each other in the peripheral region 15, where the layering has Occurs when first opened.

In other examples, the pressure sensitive adhesive between the adhesive label 7 and the laminate 2 can be patterned. For example, the adhesive coating layer weight of the pressure sensitive adhesive between the adhesive label 7 and the first region 8 can be increased to provide a stronger bond between the adhesive label 7 and the first region 8. . This will prevent the first region 8 from being layered by the adhesive label 7 during use.

Alternatively, the adhesive label 7 can be attached at least partially to the laminate 2 with a permanent adhesive, in particular in the first region 8 of the laminate 2. This permanent adhesive will prevent the first region 8 from being separated by the adhesive label 7 during use.

In other examples, the laminate 2 and/or portions of the adhesive label 7 may be non-adhesive, such as assisting the opening and closing movements.

Figure 4 shows another example of a packaging material 1 for forming a package bale. In this example, the second cut line 6 formed in the second layer 4 of the laminate material 2 does not extend to the top edge 11 of the first cut line 5, as described with reference to Figures 1-3. The second cutting line 6 extends from the bottom edge 13 of the second cutting line 6 in a direction parallel to the opposite side edges 10 of the first cutting line 5 and then faces the first cutting line 5 The side edges 10 partially intersect along opposite side edges of the first cutting line 5.

As for the previous example, the packaging material 1 is provided with an adhesive label 7 applied over the first cutting line 5 on the first layer 3 of the laminate material 2. The pulling on the pulling tab 17 of the adhesive label 7 causes the first and second layers 3, 4 of the laminate 2 to separate along the first and second cutting lines 5, 6, respectively, creating an opening.

In this example, the peripheral region 15 between the first and second cutting lines 5, 6 which are layered when the packaging material 1 is opened only partially extends around the opening. Therefore, if a pressure sensitive adhesive is provided between the first and second layers 3, 4, the first and second layers 3, 4 will be only in the peripheral region 15 when the packaging material 1 is superposed. Reattach to each other.

In a variation, the second layer 4 is torn along the first cutting line 6 in the region above the second cutting line 6. That is, since the second cutting line 6 extends only partially along the side edge 10 of the first cutting line 6, when the adhesive label 7 is pulled, the remaining portion of the second layer is torn. This tearing will occur along the first cutting line 5 as this is the weakest point of the laminate 2.

In another variation, the first cutting line 6 extends through the first and second layers 3, 4 in a region above the point where the second cutting line 6 intersects the side edge of the first cutting line 5 10. Therefore, the first layer 3 is separated along the entire first cutting line 5 when the adhesive label 7 is pulled, and the second layer 4 is along the entire second cutting line 6 and then in the second cutting The line 6 is spaced apart along the side edges of the first cutting line 5.

In another example, as shown in FIG. 5, the first cutting line 5 in the laminate 2 is constrained to be disposed adjacent to the open cut of the pull tab 17. That is, the side edge 10 of the first cutting line 5 extends only a limited distance. Similar to the example of FIG. 4, the second cutting line 6 extends from the bottom edge 13 of the second cutting line 6 in a direction parallel to the opposite side edges 10 of the first cutting line 5, and then toward the first The opposite side edges 10 of the cutting line 5 intersect the first cutting line 5 at the end 39 of the first cutting line 5. Furthermore, the second cutting line 5 comprises a further side edge 38 which extends from the end 39 of the first cutting line 5 in the same direction as the side edge 10 of the first cutting line 5.

Therefore, in this example, when the pulling tab 17 is pulled, the second layer 4 is separated along the second cutting line 6, and the first layer 3 is along the first cutting line. 5 is separated, and then torn along the other side edge 38 of the second cutting line 6.

The peripheral region 15 is defined between the first and second cutting lines 5, 6 immediately adjacent to the pulling tab 17, wherein the first and second layers 3, 4 are layered when the wrapping material 1 is opened.

The above combination of the first and second cutting lines 5, 6 in the laminate 2 and the adhesive label 7 covering the first cutting line 5 provides a labyrinth seal, such as air or other gas, Or a liquid, or vapor, fluid must pass through the labyrinth seal to rupture the package material 1. Moreover, this configuration provides a convenient mechanism for quickly and easily opening the package 1 to provide an opening 19 through which the contents can be accessed.

Moreover, in some examples, the package bale formed by the wrapper 1 may be provided with a partial vacuum or increased pressure therein. In this case, the above configuration of the cutting lines 5, 6 and the adhesive label 7 provide a strong and durable seal that maintains the pressure differential over an extended period of time.

Figures 6A and 6B show partial cross sections of the packaging material 1 described above with reference to Figures 1 to 5, having different laminate materials 2.

Figure 6A shows a cross section of a packaging material 1 having a laminate material 2 having two layers, as is explicitly described with reference to the examples of Figures 1 to 5. That is, the laminate material 2 has a first layer 3 that is bonded to the second layer 4.

A first cutting line 5 is provided in the first layer 3, and a second cutting line 6 is provided in the second layer 4, the first and second cutting lines 5, 6 being offset as previously described .

Figure 6A also shows the adhesive label 7, which is applied to the first layer 3 of the laminate 2. As indicated in FIG. 6A, between the first and second layers 3, 4, the The peripheral region 15 previously defined by the first and second cutting lines 5, 6. The overlap region 16 between the first layer 3 and the adhesive label 7 is also defined by the first cutting line 5 and the bottom edge 18 of the adhesive label 7.

As shown, the arrangement of the offset first and second cutting lines 5, 6 and the adhesive label 7 covering the first cutting line 5 provides a labyrinth barrier through which the substance will have to travel. The package is formed by entering or leaving the package formed using the packaging material 1. Thus, the configuration of the adhesive label 7 and the cutting lines 5, 6 provides a strong and durable seal.

Fig. 6B shows another alternative example of a packaging material 1 having a laminate material 2 having a first layer 3, a second layer 4, and a third layer 21. The third layer 21 is disposed between the first and second layers 3, 4, and the first and second layers 3, 4 are joined to opposite sides of the third layer 21.

In this example, the first layer 3 and the third layer 21 are joined using a pressure sensitive adhesive, and the second layer 4 and the third layer 31 are permanently joined together. The first cutting line 5 is provided in the first layer 3, and the second cutting line 6 is provided in the second layer 4 and the third layer 21. The first and second cutting lines 5, 6 are offset as previously described.

Figure 6B also shows the adhesive label 7, which is applied to the first layer 3 of the laminate 2. As indicated in FIG. 6B, in this example, the peripheral region 15 is formed between the first and third layers 3, 21 and is defined between the first and second cutting lines 5, 6. . It will be appreciated that in this example, the peripheral region 15 can still be used to reattach the first layer 3 to the second layer 4, although the third layer 21 is disposed therebetween. The overlap region 16 between the first layer 3 and the adhesive label 7 is defined between the first cutting line 5 and the bottom edge 18 of the adhesive label 7.

As shown, the offset first and second cutting lines 5, 6 and cover the The configuration of the adhesive label 7 of the first cutting line 5 provides a labyrinth barrier through which the substance will have to travel to enter or exit the package bundle formed by the package 1. Thus, the configuration of the adhesive label 7 and the cutting lines 5, 6 provides a strong and durable seal.

In another alternative example similar to that of Figure 6B, the first and third layers 3, 21 are permanently joined together and the second and third layers 4, 21 are joined using a pressure sensitive adhesive. together. In this case, the first cutting line 5 is provided in the first layer 3 and in the third layer 21, and the second cutting line 6 is only provided in the second layer 4. The first and second cutting lines 5, 6 are offset as previously described.

It will be appreciated that the laminate 2 can have more than three layers joined together in a manner similar to that described above such that each of the first and second cutting lines 5, 6 is provided to one of the layers Or more than one.

Each layer may comprise one or more of a polymer, an oriented polymer, a metal foil such as an aluminum foil, a metallized polymer, or other similar flexible material for use as a package.

The layers may be permanently joined together using a permanent adhesive, i.e., an adhesive that is strongly joined together, such that when the package is opened or closed, the layers are not separated.

The pressure sensitive adhesive allows the layers of the laminate 2 to be reattached to each other after delamination. The pressure sensitive adhesive is a non-dry, permanently tacky adhesive such that the pressure sensitive adhesive can be used several times to separate and reattach the laminate 2 in the peripheral region 15. Floor.

In a preferred embodiment, the laminate 2 comprises three layers, the inner and outer layers 3, 4 being made of oriented polypropylene (OPP) and disposed on the inner and outer layers. The third layer of the 3rd and 4th floors is made of aluminum foil.

In the example, the OPP inner and outer layers 3, 4 have a thickness between 10 microns and 50 microns.

In one example, the OPP layers are preferably between 10 microns and 30 microns, more preferably about 20 microns thick. This has been found to provide a suitable seal for preventing fluid from entering through the first and second cutting lines 5, 6.

In another example, the OPP inner and outer layers 3, 4 have a thickness between 30 microns and 50 microns, and more preferably about 40 microns. This has been found to provide sufficient stiffness in the laminate 2 for repeated opening and closing while limiting material utilization.

In an example, the aluminum foil has a thickness between 5 microns and 20 microns, preferably between 5 microns and 15 microns, and more preferably about 9 microns.

The first and second cutting lines 5, 6 can be formed in the laminate 2 using a mechanical cutter having a limited, predetermined depth of cut. That is, the mechanical cutter is designed to cut through the appropriate layers and not cut through the other layers in the manner previously described. This process is known as die cutting or tapping.

Alternatively, the first and second cutting lines 5, 6 can be formed using a laser. For example, the first laser can be constructed to cut the outer layer 3, but the inner layer 4 is not cut, and the second laser can be constructed to cut the inner layer 4 without cutting the outer layer 3. Any of the lasers can be constructed to also cut the third layer 21. Thus, the lasers can be constructed to cut the layers of the laminate 2 in any of the manners previously described, with reference to Figures 6a and 6b.

In a preferred embodiment, the laminate 2 comprises an inner layer and an outer layer 3, 4 made of oriented polypropylene (OPP), and is made of a metal foil, such as an aluminum foil. The third layer 21 is as illustrated in Figure 6b. In this case, laser energy can be used to form the first and second cutting lines 5, 6.

A first laser that can only cut through the OPP forms a first cutting line 5 in the outer layer 3 from the side of the outer layer 3. The first laser cannot cut through the third layer 21 of the aluminum foil, so the first cutting line 5 is confined to the outer layer 3.

A second laser that can cut through the aluminum foil forms the second cutting line 6 in the inner layer 4, and a third layer 21 is formed from the side surface of the inner layer 4. When the second cutting line 6 is formed, the second laser beam passes through the inner layer 4, is incident on the third layer 21 (aluminum foil), and the third layer 21 is cut, and part of the energy is reflected back. Towards the inner layer 4, it causes the inner layer 4 to also be cut. Therefore, the second laser will form a cutting line only in the third layer 21 and the inner layer 4.

The first and second laser energies can be constructed in the manner described above by selecting the appropriate wavelength and power for the material to be cut, in this example the oriented polypropylene and/or aluminum foil.

It will be appreciated that other packaging materials can also be laser cut, and the above is only a preferred embodiment. In particular, the laser can be constructed to have an appropriate wavelength and/or power to cut through only a single OPP layer and adjacent layers that do not cut through the OPP. Thus, laser cutting can also be used to provide the first and second cutting lines 5, 6 in the two layer material 2 described with reference to Figure 6a.

Each of the first and second cutting lines 5, 6 in the laminate 2 may extend entirely through the associated layer of the laminate 2. Alternatively, the cutting lines 5, 6 may extend only partially through the associated layer of the laminate 2, and the remainder of the layer will tear when the pull tab 17 is pulled to form the opening. The polypropylene fibers can be oriented in a tearing direction to facilitate the tearing action.

Figure 7 shows a package bale 22 containing a cigarette that has been made by wrapping a package of cigarettes 1 described above with reference to any of Figures 1 to 6b. The cigarettes are configured in a control and then wrapped in a slender cylindrical article in the package 1. As shown, the packaging material 1 has been folded around a group of cigarettes such that the adhesive label 7 is placed on one end portion 23. The end portion 23 of the package bundle 22 having the adhesive label 7 corresponds to the end of the cigarette so that when the adhesive label 7 is pulled to establish the opening (see Figure 3 where the component symbol 19 is indicated) At the time, the cigarette can be drawn long by the package bundle 22.

In the example shown in Figure 7, the end portion 24 of the wrapper 1 has been folded against the sides of the group of cigarettes. These folded ends 24 can be sealed, such as using an electromagnetic induction sealing process, a heat sealing process, or an adhesive to provide a sealed package bundle 22 of cigarettes.

As shown, the adhesive label 7 extends from the front side 25 of the package bundle 22 to the end face 23 such that pulling on the pull tab 17 to open the package bundle 1 results in an opening from the front side 25 Extending into the end face 23 of the package bundle 1. This makes it possible to grip the cigarettes bilaterally for easy removal by the package bundle 22.

Figure 8 shows another example of a package bundle 22 that has been made by wrapping the above-described packaging material 1 around a group of cigarettes. As shown, the wrapper 1 has been folded around a group of cigarettes such that the adhesive label 7 is on one end 23. The end portion 23 of the package bundle 22 having the adhesive label 7 corresponds to the end of the cigarette. Thus, when the adhesive label 7 is pulled to establish the opening (see where the symbol 19 is indicated in Figure 3), the cigarettes can be drawn longitudinally from the package bundle 22.

In this example, the end 24 of the wrapper 1 is sealed in a fin shape. That is, in the region of the end portion 24 of the packaging material 1, the laminate material 2 has been bonded to itself, Wing seals 26, 27 are formed. These fin seals 26, 27 can then be folded against the sides of the package bundle 22.

FIG. 9 shows a first general example of a process for forming a fin-shaped sealed package bundle 22. In this example, the wrapper 1 is folded around a group of cigarettes 28 and an inner frame 29 that is provided to support and protect the cigarettes 28 within the package bale (see where component symbol 22 is indicated in Figure 8). .

As shown, the cigarettes 18 are first placed into the inner frame 29, such as by folding the inner frame 29 around the group of cigarettes 28, and then the package 1 can be wrapped around the inner frame 29.

The ends 24 of the wrap are then finned to each other to form a first fin seal 27 that causes the tubular wrap 1 to surround the inner frame 29. The ends 24 of the tubular package 1 are then sealed together in a fin shape to form second and third fin seals (see Figure 8 where the component symbol 22 is indicated).

In this example, as shown in FIG. 8, the fin-shaped package bundle 22 has a first fin seal 27 extending across the rear face 30 of the package bundle 22, and is seated with the adhesive label 7. The front 25 is opposite. The second and third fin seals 26 extend along opposite sides 31 of the package bundle 22.

In another example, schematically shown in FIG. 10, the first fin seal 27 can be formed over the end face 32 of the package bundle 22 opposite the end face 23 having the adhesive label 7. The second and third fin seals 26 can then be formed along opposite sides 31 of the package bundle 22.

In another alternative, the first fin seal 27 can be formed over the front side 25 of the package bundle 22 below the adhesive label 7.

The fin seal can be pressed together by pressing the parts of the laminate Heat and/or an adhesive is applied to join the parts of the laminate together. This heat can melt and/or fuse the components of the laminate together.

As noted above, the fin-sealed package bundle 22 will provide a strong and durable hermetic seal that maintains differential pressure. For example, the interior of the package bundle 22 can be at a pressure above or below atmospheric pressure.

The increased pressure within the package bundle 22 can be provided by adding air, or a gas, or liquid, to the interior of the package bundle 22 prior to forming the final seal.

In various examples, the pressure within the package bundle 22 is above atmospheric pressure, i.e., greater than 1 bar. In some examples, the pressure within the package bundle 22 can be between 1 bar and 2 bar, more specifically between 1.25 bar and 1.75 bar, preferably about 1.5 bar.

Alternatively, prior to forming the final seal, reduced pressure, such as partial vacuum, can be provided to the interior of the package bale 22 by drawing air, such as by performing a reference in FIG. 9 or FIG. 10 in a low pressure environment. The packaging and sealing process described.

In some examples, the pressure in the interior of the package bundle 22 is less than 500 mbar, such as between 40 mbar and 300 mbar. In other examples, the pressure in the interior of the package bundle 22 is less than 150 mbar, preferably about 80 mbar. However, it will be appreciated that the partial vacuum within the interior of the package bundle 22 can be any value less than 1 bar.

Alternatively, the package bundle 22 can be provided with a one-way valve that is designed to allow flow of air in one direction and not in the other. The valve on the package bundle 22 can then be provided with a source of high pressure or low pressure to move air in or out of the package bundle 22.

In addition, the interior of the package bundle 22 can be provided with an improved atmospheric pressure, such as A gas other than air, such as an inert gas.

Alternatively, other materials may be added to the interior of the package, such as a liquid, and allowed to evaporate within the package bundle 22, such as by increasing the pressure within the package bundle 22.

In other examples, the adhesive label 7 can be provided to increase the stiffness of the cover flap formed by the adhesive label 7 and the first and second regions 8, 12 of the laminate 2. For example, if the laminate 2 is made of a thin and easily deformable material, the adhesive label 7 can be provided to increase the hardness and prevent fold lines or deformations that prevent the first and second portions. The regions 8, 12 are replaced above the opening 19. In this case, the adhesive label 7 does not need to cover the first cutting line 5 and does not need to contain any pressure sensitive adhesive.

As shown in FIG. 11, various examples of the package bundle 22 described with reference to FIGS. 1 through 10 can be received within the hinged lid package 33.

Alternatively, the package bundle 22 can be provided as its package itself without any other package or lid.

As shown in FIG. 11, the hinged lid package 33 has a base 34 in the form of a parallelepiped and is designed to receive the package bundle 22 such that the package bundle 22 is from the base 34. The open end 35 protrudes. In this position, the adhesive label 7, and in particular the pull tab 17, is accessible for opening the package bundle 22 and providing access to the cigarettes therein.

A cover 36 is attached to the base 34 about a rotating shaft 37. The lid 36 is pivotable between a closed position in which the lid 36 covers the package bundle 22 and an open position in which the package bundle 22 is exposed. Figure 11 shows the cover 36 in the open position such that the user can grasp the pull tab 17 and pull on the adhesive label 7 for the package 1 The opening (19, see Fig. 3) is formed in the middle for extracting the cigarette.

In other examples, shown in Figures 12 and 13, the pull tab 17, or another portion of the adhesive label 7, can be attached to the lid 36 such that opening and closing the lid 36 simultaneously opens and closes. The package bundle 22 in the package 33.

In one example, shown in FIG. 12, the outer side of the pull tab 17 is attached to the inner side 40 of the cover 36. In this way, when the cover 36 is opened, the pulling tab 17 is pulled, which simultaneously establishes the opening 19 in the package bundle 22. When the lid 36 is overlapped, the adhesive label 7 and the laminate 2 will be repositioned, closing the opening 19. If a pressure sensitive adhesive is provided in the laminate 2 and/or on the adhesive label 7, the opening 19 can be resealed.

In another example, shown in FIG. 13, the pull tab 17 is folded against the adhesive label 17, and the bottom side of the pull tab 17 is adhered to the inner side 40 of the cover 36. This results in simultaneous opening similar to that described with reference to FIG.

In each of FIGS. 12 and 13, during the operation of the cover 36, the adhesive label 7 and the laminate 2 are attached to a portion of the adhesive label 7 to maintain an outwardly convex shape. As shown in Figures 12 and 13. This means that when the lid 36 is manipulated, the adhesive label 7 and/or the peripheral region 15 are gradually peeled off and then reapplied to the laminate 2.

It will be appreciated that the above-described examples of the package 1 comprising the package bundle 22 and the hinged lid package 33 can be used to package tobacco industry products that are different from cigarettes.
