032373 B1

Technical field

The present invention relates generally to the packaging of smoking tobacco products, for example cigarettes, cigarillos and / or cigars. In particular, the invention relates to a resealable pack of smoking tobacco products and a method for packaging smoking tobacco products.

Technical background for the invention

In order to protect packaged smoking tobacco products and preserve their taste and freshness, resealable packs for smoking tobacco products are proposed.

Known resealable packs for smoking tobacco products can be useful for better preserving the taste and quality of smoking tobacco products contained in such a pack than in traditional packs that do not allow them to be tightly closed again to avoid the escape of flavor from packaged smoking tobacco products. into the environment and / or to prevent unwanted moisture from entering from the outside.

From time to time, a smoker may want to smoke one of the smoking tobacco products contained in a pack of smoking tobacco products. Therefore, such a user repeatedly opens and closes a known re-closing pack with a gradual removal from it and consumption of smoking tobacco products until the pack is empty. In the period between the instant of the first opening of the known re-closing pack and the instant in which the last smoking article is taken from the packet, some odor disappears from the smoking tobacco products remaining in the packet and some loss of freshness thereof. A known container in a wrapper (I8 2011/0147443 A1), applicable for packaging tobacco products. The set of products is wrapped in an inner shell and enclosed in a container, after which the filled container is enclosed in an outer wrapper. For re-sealing the opening of the inner shell of the container, a peel-off sticker is provided that is mounted on a separate carrier so that it is necessary to open the hole to retrieve or review the product.

In addition, a pack of tobacco products is known (νθ 2010/066543 A1), including a container and packaging of insulating material for packaging a set of tobacco products. The layer of insulating material has an opening for access, which is closed by a movable cover with the possibility of opening. As the material of the barrier layer and the lid, metallized plastic or foil film is described. And again, for access or review of products, it is necessary that the hole is open.

Thus, in light of the foregoing, it would be desirable to be able to offer smoking tobacco products, such as cigarettes, cigarillos and / or cigars, packaged in a resealable pack that has an even higher protective effect and reduces the loss of aroma and freshness to an even greater extent and which, however, can be conveniently used.

It would also be desirable to offer users a package that reduces the need to open the pack in order to find out how many cigarettes are left in it, thereby further improving the retention of aroma and freshness.

Disclosure of invention

Therefore, one object of the present invention is to provide a resealable pack of smoking tobacco products with enhanced protective effect, which can also be conveniently used. Another objective of the present invention is to propose a correspondingly improved method of packaging smoking tobacco products.

According to the invention, the technical problem described above is solved by a resealable pack of smoking tobacco products having the features according to claim 1. In addition, this problem is solved by a method having the features of claim 13 of the claims.

Accordingly, the present invention provides a resealable pack of smoking tobacco products, which includes an airtight protective shell suitable for containing a number of smoking tobacco products. The protective shell is adapted to open to allow the user to take one or more smoking tobacco products from the pack. Moreover, the casing is adapted for subsequent re-closing in order to restore the protection of packaged smoking tobacco products or their remainder from changes in aroma and freshness, in particular due to loss of moisture or its entry into the pack. In accordance with the invention, the shell includes a component that is at least partially translucent, preferably transparent, and which allows the user to see the contents or the rest of the contents of the pack through this component from the outside of the shell in its re-closed state.

A method of packaging smoking tobacco products, which is proposed in accordance with the present invention, includes the following steps:

the provision of a group of smoking tobacco products;

placing this group in a sealed containment.

The shell is adapted to open to allow the user to take one or more smoking tobacco products from the pack. In addition, the casing is adapted for subsequent re-closing in order to restore the protection of packaged smoking tobacco products or their

- 1,032373 residues from changes in aroma and freshness. The envelope in which the tobacco products are enclosed includes a component that is at least partially translucent, preferably transparent, and which allows the user to see the contents or the remainder of the contents of the pack from the outside of the envelope in its re-closed state.

The idea underlying the present invention is to offer a resealable pack with a component that enables a user (eg, smoker) to check the contents of the resealable pack and, in particular, to determine at least approximately how many smoking tobacco products left in a resealable bundle, without the need to open the protective shell. Therefore, the user can check whether smoking tobacco products remain without having to open and subsequently re-close the casing for this purpose. Thus, a resealable pack has been proposed which is more convenient than the known reclose packs because the rest of the contents can be easily and quickly determined.

Therefore, when using the resealable pack according to the invention, it is also possible to avoid frequent opening by the user of the sealed protective sheath only to check the contents of the pack, even if he actually does not want to take the tobacco product from the pack at this time. Therefore, the shell of the resealable packs according to the invention will be opened by the user much less frequently than the known resealable packs for smoking tobacco products. In addition, the ability of the user to re-close the shell incorrectly or partially is reduced, since the number of re-closing operations is minimized.

Accordingly, the favorable protective environment created by the sealed containment can be better maintained. Therefore, the freshness, quality and taste of smoking tobacco products can be preserved even better than in the case of known re-closing packs.

The advantages and benefits just indicated are also achieved by carrying out the method for packaging tobacco products of the invention.

Other preferred variations, extensions and improvements of the present invention are indicated in the dependent claims, as well as in the detailed description of the invention, which contains references to the figures.

In the framework of this application, a transparent material or element should be understood as a material or element through which light can pass and which also allows the user, in particular a person, to more or less clearly recognize and identify objects placed behind such material or element. Those. light passes through such a material or element essentially without scattering. A translucent material or element in the context of this application should be understood as allowing the user to recognize and identify, at least to some extent, the objects behind such material or element. However, it should be understood that the degree of transparency of different translucent materials may be different and that the term translucent, which is used here, is not intended to limit the degree of transparency to any particular numerical value. Therefore, a transparent material can be understood as one specific case of a translucent material having a high degree of transparency. However, this application also contemplates materials that are translucent and have a degree of transparency much lower than the degree of transparency of a fully transparent material.

In addition, in the context of this application, an opaque material or element should be understood as capable of allowing light to pass through it, but not allowing the user to recognize or identify objects placed behind such an opaque material or element. And, in conclusion, a lightproof material or element, in the sense that this term is used here, should be understood as indicating a material or element that completely does not allow light to pass through it.

According to one preferred embodiment, such a component is designed as an element for repeatedly opening and re-closing the shell. In particular, the component may be made in the form of a valve of flexible sheet material. Thus, the element used to repeatedly open and re-close the shell, at the same time, is advantageously used as an element that provides visual access to the user from the outside of the shell to the space inside it. Thus, it is preferable that the functions of visual access and opening and re-closing of the protective sheath are combined in one component. A resealable pack with such a valve-shaped component can be convenient to manufacture. If desired, even large portions of the contents surrounded by the protective sheath may be coated with a lightproof rigid outer casing or a lightproof outer wrap without impairing the visual access function provided by such a component. With this design, the user can easily check the contents of the pack and, if desired, open the shell in the same area of the pack.

According to one embodiment, the component is designed as an element for repeated

- 2 032373 opening and re-closing the shell, in particular in the form of a valve made of flexible sheet material connected by glue to a sealed protective sheath. This, in addition, can contribute to the convenience of producing the bundle and the usability of the bundle by the user.

In accordance with another preferred embodiment, the sealed protective sheath includes an insulating sheet, which may be particularly flexible. An insulating sheet is located around the packaged smoking tobacco products. The insulation sheet may be made, in particular, of a suitable material that is adapted to protect smoking tobacco products from loss of taste and freshness by, for example, preventing the escape of aroma from packaged smoking tobacco products into the external environment and / or preventing unwanted ingress of moisture from the outside. To provide the desired protective properties, the hermetic protective sheath can be made of the insulating sheet relatively simply and economically by placing the insulating sheet around a group of smoking tobacco products and then sealing the insulating sheet, if necessary. Sealing can be accomplished, for example, by creating suitable tight seams with a suitable sealing device. The flexible insulating sheet can be easily folded around a group of tobacco products.

In accordance with one preferred embodiment, the component is glued to an insulating sheet. By selecting a suitable adhesive, the component can conveniently be implemented as a means, such as a valve, which can be repeatedly detached from the insulating sheet, at least partially, to open the shell and which can be folded or bent repeatedly into its original position for tightly closing the shell .

In accordance with another preferred embodiment, the component is a valve that is manufactured separately from the insulating sheet and which is attached to the insulating sheet to obtain a resealable bundle. Thus, an insulating sheet and a valve can be easily manufactured.

In accordance with another preferred embodiment, the insulating sheet may be made of a laminate.

According to another preferred embodiment, the insulating sheet may be made of a heat-adhesive or self-adhesive material, in particular a heat-adhesive laminate or a self-adhesive laminate. If the material of the insulating sheet is heat-sensitive, the seams of the shell can be made using an appropriate device.

According to another preferred embodiment, the insulating sheet or at least a portion of the insulating sheet is transparent or translucent. Thus, smoking tobacco products may be visible, at least in part, from the outside of the casing through the insulating sheet or part thereof.

According to another preferred embodiment, the insulating sheet or its transparent or translucent part may be overprinted. By overprinting, the appearance of the insulating sheet or the transparent or translucent part of the insulating sheet can be further improved and information that may be useful to the user can be applied. Such information may relate, for example, to the type of smoking tobacco products contained in the pack, their variety and / or their taste.

According to another preferred embodiment, a component that is at least partially translucent or at least partially transparent is located at least partially on a transparent or translucent insulating sheet or on the transparent or translucent part of the insulating sheet. Thus, the transparency or translucency of the insulating sheet or part thereof together with the transparency or translucency of the component can provide visual access to the user from the outside of the sheath through the parts of the component and the insulating sheet. Due to this, a preferred resealable bundle can be obtained, which can be easy to manufacture, since it will not be necessary to provide an insulating sheet with a notch in the region where the component is located.

According to another embodiment, the insulating sheet is opaque or opaque. Due to this, the smoking tobacco products contained or their remainder can be at least partially visible to the user in the re-closed state of the packet due to the transparency or translucency of the component or its parts, while the smoking tobacco products do not pass through adjacent parts of the opaque or opaque insulating sheet visible. This, in addition, creates a variant of the reclosable pack having an improved appearance. Moreover, if a group of smoking tobacco products surrounded by a protective sheath must be inserted into a lightproof outer casing or wrapped with a lightproof outer wrap during packaging, such an outer casing or outer wrap may not provide visual access through at least a portion of the insulating sheet. Therefore, in this case, it is not necessary that the entire insulating sheet is transparent or translucent.

The insulation sheet may include an opening for user access to products wrapped in this insulation sheet. In this case, the component closes the access hole in the original closure.

- 3 032373 the condition of the shell. The component is then fitted to and connected to the insulating sheet so that the component can be at least partially lifted from the insulating sheet in order to open at least a portion of the access hole and open the shell, providing the user with access to smoking rooms tobacco products. In addition, the component in this case is adapted for subsequent re-closing of the access opening and re-closing of the casing. This embodiment is particularly suitable when the insulating sheet is opaque or opaque.

The visual access of the user into the shell is provided through at least partially a transparent or at least partially translucent component and an access hole closed by the component. After opening the casing by partially lifting the component, the user can take out the tobacco product through the access hole.

According to another preferred embodiment, the insulating sheet is provided with a tear line along which the insulating sheet can be torn to form an access opening. In the initial closed state of the shell, the component closes the tear line and the area of the access hole to be formed. Moreover, the component is fitted and connected to the insulating sheet so that the component can be at least partially lifted from the insulating sheet in order to cause the insulating sheet to tear along the tear line and form openings for access in the shell. Through this, the user is given the opportunity to access smoking tobacco products, in particular in order to take one or more smoking tobacco products from the pack. The component is furthermore adapted to subsequently close the formed opening for access and re-close the casing. The resealable bundle according to this embodiment has the advantage, for example, that it is quite simple to make it if the insulating sheet or at least part of the insulating sheet is transparent or translucent, since the user can get visual access through the insulating sheet or its transparent or translucent part and through a component located on the insulating sheet. In this case, the break line is enough to define the access hole. At least a partially detachable part of the insulating sheet in the region of the access opening bounded by the former tear line can remain connected to the component after the first opening operation, while not making visual access to the inside of the casing difficult. Also in the case of this embodiment, smoking tobacco products, and in particular their ends, can be advantageously protected against accidentally sticking to the component by means of at least partially detached portion of the insulating sheet that remains connected to the component.

In accordance with yet another embodiment, the tear line can be made as a perforation line. This is a fairly simple way to get a certain line of tear in the insulating sheet.

In accordance with another embodiment, the component is completely transparent or translucent. According to one alternative embodiment, the first part of the component is transparent or translucent, and the second part of the component is opaque or opaque. Essentially, a fully transparent or translucent component can create a large area of visual access for the user, facilitating the visibility of the content or its residue. On the contrary, the second part of the component, which is opaque or opaque when the first part is transparent or translucent, can also improve the appearance of the resealable pack, for example by highlighting or visually highlighting the transparent or translucent first part.

In accordance with another embodiment, the first part of the component is made as a transparent or translucent window, which is limited to at least part of its circumference by an opaque or opaque edge. The edge in this embodiment is formed by the second part of the component. In this embodiment, the access window and opening overlap or substantially coincide in the closed and / or re-closed state of the shell. In particular, the access window and opening may overlap fully or partially. In this embodiment, the appearance of the resealable bundle is further improved and the window in the component is highlighted. Although, in particular, in the case of a transparent or translucent insulating sheet, it is not necessary to arrange the access window and opening so that they overlap or overlap fully or partially, but matching or overlapping access window and opening is preferred.

According to another embodiment, the component or the first part of the component is imprinted. The overprint on the transparent or translucent part of the component can create a new improved appearance of the packet and, in addition, can provide the user with important information that may relate, for example, to the type of smoking tobacco product, its brand, taste, etc. or contain instructions for proper use. Since the component allows the user to see the content remaining in the re-closing pack, the user's attention is also drawn to the important information printed on the component.

According to yet another embodiment, the component may be made of cellophane or polypropylene based sheet material.

- 4 032373

In particular, the component can be made of cellophane-based sheet material having suitable protective properties for protecting smoking tobacco products, while also being environmentally friendly, in particular having sufficient biodegradability and / or manufactured without harming the environment.

For example, according to one embodiment, a film of the type offered by the company ило у п о о о о ^ ^ о η η η can be used as a component. Cumbria County, UK, under the brand name YaShgeNeh ™.

According to yet another embodiment, the resealable bundle is further provided with a soft outer wrapper of flexible sheet material, wherein the contents that are enclosed in a sealed protective sheath are a resealable inner bundle wrapped in an outer wrapper. Alternatively, the packet may include a rigid or semi-rigid outer casing. The contents enclosed in a sealed protective sheath are then a resealable inner pack contained in the outer case. The outer wrapper or outer case also protects the smoking tobacco products in the pack and the protective sheath, for example from mechanical damage during transport.

In accordance with another embodiment, the rigid or semi-rigid outer casing may be made of cardboard of a suitable type.

In particular, a rigid or semi-rigid outer casing may be designed as an outer casing including a hinged lid.

According to another embodiment, the resealable bundle further includes an internal support frame. The frame is located inside the shell between the portion of the smoking tobacco products contained therein and the portion of the shell. Such an internal supporting frame can be made, in particular, of semi-rigid material, for example of cardboard of the appropriate type. The inner frame may help protect smoking tobacco products and / or the insulating sheet from damage caused by pressure on the pack. Thus, this skeleton gives the packet structural stability also when a certain number of smoking tobacco products have already been taken. An internal support frame can also facilitate re-closing operation, providing sufficient support.

In accordance with yet another embodiment, the resealable packet further includes an external support frame that is located outside the casing and covers part of the tobacco products enclosed in a sealed protective casing. The outer support frame may be made, in particular, of semi-rigid material, such as suitable cardboard. By means of an external support frame, it is possible to protect smoking tobacco products and the protective sheath from mechanical stresses on the packet.

According to various embodiments of the invention, the resealable bundle may include either an internal support frame, or an external support frame, or both support frames.

The embodiments described above can be applied to the packet of the invention, as well as to the method of the invention.

According to one embodiment of the method for packaging smoking tobacco products, the packaging of smoking tobacco products comprises providing an insulating sheet, in particular a flexible insulating sheet, which includes an access opening, wherein the component is glued to the insulating sheet to close the access opening. The provided insulating sheet is arranged around the tobacco products.

According to one alternative embodiment, the packaging of tobacco products comprises providing an insulating sheet, in particular a flexible insulating sheet, which includes a tear line along which the insulating sheet must be torn to form an access opening. The component is glued to the insulating sheet to close the tear line and the area of the access hole to be formed. The provided insulating sheet is arranged around the tobacco products.

According to another embodiment of the method, after the insulating sheet is placed around the tobacco products, the insulating sheet is sealed, in particular by means of hermetic seams, in order to obtain an airtight protective sheath.

Preferably, the method of packaging smoking tobacco products is performed using an insulating sheet, transparent or translucent.

The method proposed by the invention can be used, in particular, for the manufacture of a resealable pack according to the invention.

The embodiments, enhancements, and enhancements described above may be arbitrarily combined with each other when it makes sense. Other possible embodiments, extensions and implementations of the invention include combinations of features of the invention that are described above or will be described below in connection with a detailed description of embodiments, even if such a combination is not explicitly mentioned.

Detailed Description of Embodiments

In FIG. 1 part of the flexible insulating sheet 1 is shown in plan view. The insulation sheet 1 is preferably made of a flexible sheet material that has properties suitable for protecting smoking tobacco products (not shown in FIG. 1), such as cigarettes, cigarillos or cigars, from volatilization and loss of aroma and taste, as well as from moisture from the outside. Sheet material

- 6 032373 for the insulating sheet can also be adapted to protect against other external influences that may impair the taste and quality of smoking tobacco products. As an example, the sheet material for forming the insulating sheet 1 may be a laminate, such as a heat-adhesive or self-adhesive laminate.

As shown in FIG. 1, the insulating sheet 1 is provided with a tear line 3, which in the example shown has the form of a substantially I-shaped perforation line. Gap line 3 limits the portion or region 6 that is shown in FIG. 1 by hatching and in which an opening for access 10 is made, the function of which will be described in more detail below, when the insulating sheet 1 is torn along the tear line 3 and the remaining part of the insulating sheet 1 is bent in region 6, for example, to the left in FIG. one.

In FIG. 1, the insulating sheet 1 has not yet been torn along the tear line 3. The component 15 is located on one side, in this case on the upper, insulating sheet 1 and is glued to the insulating sheet 1, essentially on the entire surface of the component 15, which faces the insulating sheet 1. Component 15 completely covers the gap line 3 and region 6.

Component 15 is in the form of an adhesive valve, which is also made of flexible sheet material. The sheet materials used for the valve 15 and for the insulating sheet 1, respectively, can be of different types. The adhesive for connecting the component 15 to the insulating sheet 1 is selected so that the component 15 can conveniently be disconnected and lifted from the insulating sheet 1, at least partially, in the direction of arrow 19 in FIG. 2. For this purpose, the user can lift the component 15 beyond its edge 15a.

When component 15 is lifted, at least in part, in this manner and folded or folded to the left, as shown in FIG. 2 by a dashed line, the insulation sheet 1 is torn along the tear line 3. Due to this, an access hole 10 is formed. In addition, the adhesive with which the component 15 is connected to the insulation sheet 1 is selected so that the component 15 for closing and re-closing the hole for access 10 it was possible to bend back into place and again tightly connect with the insulating sheet 1, thereby tightly closing the opening for access 10. Preferably, the component 15 is adapted to rise from the insulating sheet 1 to open the hole for access 10, and placing it back in its place to re-close the access hole 10 repeatedly after the initial formation of the access hole 10.

In FIG. 1 and 2, the insulating sheet 1 is made of a substantially completely transparent material. In addition, component 15 of FIG. 1, 2 is also made of a substantially completely transparent material. It should be said that either the insulating sheet 1 or the component 15 of FIG. 1, 2, or both of them can be translucent or translucent, and not completely transparent.

This means that the object O placed behind the insulating sheet 1 in the region of the component 15 can be at least partially visible to the user when the latter is looking through the component 15. In FIG. 2, this is schematically shown by the eye of user E. In particular, the user can see what is behind the insulating sheet 1 in region 6.

It should be said that, as an option, if desired, the insulating sheet 1 may also include a transparent or translucent translucent part 2a, as well as an opaque or opaque part 2b, with the component 15 located on the transparent or translucent part 2a. This is schematically shown in FIG. 1A.

Component 15 can be made, for example, of a sheet material based on cellophane or polypropylene. If cellophane-based sheeting is used, it is possible to envisage the use of a material that sufficiently meets environmental requirements. For example, for component 15, you can use the film offered by 1ppou1a Рішк Ыб. o £ ΧνίβΙοιι County Cumbria, UK, under the brand name ааіигеР1ех ™.

In FIG. 1 shows a portion 21 in which a transparent or translucent component 15, or a transparent or translucent insulating sheet 1, or both of them may be overprinted. For example, at area 21, ornaments, symbols, logos, or important notes and instructions for the user may be printed. Thus, such comments and information, for example, will be easily perceived by the user, while the objects located behind the insulating sheet 1, however, will remain visible through the component 15 and the insulating sheet 1.

In FIG. 3 shows an insulating sheet 1 and a component 15 for a resealable pack according to the second embodiment. In FIG. 3, the insulating sheet is opaque or opaque, but can be, as an option, transparent or translucent. In order to see through component 15 what is behind the insulating sheet 1, the insulating sheet 1 of FIG. 3 includes an access hole 10, which in FIG. 3 has an approximately rectangular shape with rounded corners. The edge of access hole 10 is shown by a dashed line. On the insulating sheet 1 of FIG. 3, component 15 is arranged as a valve of flexible sheet material, which essentially has the same properties as component 15 of FIG. 1 with respect to its adhesive connection with the insulating sheet 1. However, component 15 of FIG. 3 includes a first part 16a which is transparent and a second part 16b which is opaque. It should be said that the first part 16 of component 15 of FIG. 3

- 7 032373 may also be translucent. In addition, the second part 16b may be opaque, and not just opaque. The first part 16a in this example is designed as a transparent window. In FIG. 3, the border of the window 16a is indicated by a reference symbol 17. The second part 16b is made as an opaque or opaque edge that borders the first part 16a around the circumference.

As shown in FIG. 3, the first part 16a and the access hole 10 are substantially the same, in this example, the access hole 10 is slightly larger than the transparent window. In one embodiment, the window formed by the first part 16a and the access hole 10 may be located in an overlapping relationship, as schematically shown in FIG. BACKGROUND, where the entire window 16a overlaps with part of the access hole 10.

In FIG. 3 and 4, it is shown that the component 15 according to the second embodiment completely closes the access opening 10. As in the case of FIG. 1 and 2, the component 15 can be raised, for example, by its edge 15a in the direction of the arrow 19. The portion 20 of the component 15 can be free of glue to facilitate lifting the component 15.

In the example of FIG. 3 and 4, component 15 is not provided with glue on its entire surface that faces the insulating sheet 1. Instead, glue is applied to the peripheral portion 18 of component 15, located around but outside the access hole 10. Section 18 is in the example of FIG. 3 by the second part 16b of the component 15. In this way, the sticking of the component 15 to the products placed behind the insulating sheet 1 in the area of the access opening 10 can be avoided.

In the example of FIG. 3, component 15, also, in particular on the transparent or translucent first part 16a, may be overprinted, for example, in a portion 21 shown in FIG. 3 dash-dotted line. As in FIG. 1, the overprint may include ornaments, logos, a brand of smoking tobacco products, or comments and information for the user. By arranging such comments and information on a transparent or translucent window 16a, they can be easily and quickly perceived by the user.

In FIG. 5 shows a resealable pack P of smoking tobacco products 8. Smoking tobacco products 8 are cigarettes in the case of FIG. 5. According to a first embodiment of the invention, smoking tobacco products 8 are wrapped in an insulating sheet 1, as described above with reference to FIG. 1 and 2. The insulating sheet 1, which in the case of FIG. 5 is transparent, located around group C of smoking tobacco products 8 so as to cover this group C of tobacco products. The insulating sheet 1 of FIG. 1 and 2, after being placed around group C of tobacco products, they are closed at the seams 28 and 29. Thus, after the seams 28, 29 are made, the insulating sheet 1 forms, together with the flexible valve, which is component 15, a sealed protective sheath 36, which surrounds group C of tobacco products. The shell 36 creates a protective environment for smoking tobacco products 8, protecting them, for example, from the ingress of moisture from the outside and / or from the loss of aroma. Due to this, you can save the taste and quality of smoking tobacco products 8.

As stated above with respect to FIG. 1 and 2, component 15 of packet P in FIG. 5 transparent. Therefore, as shown in FIG. 5, the user can see smoking tobacco products 8 from the outside of the pack P through the insulating sheet 1 and component 15. In order for the user to take one or more smoking tobacco products 8 from the resealable pack P, the sheath 36 can be opened by disconnecting the valve 15 starting at its edge 15a. When the component 15 is lifted from the insulating sheet 1 in the direction of the arrow 19, the insulating sheet 1 is torn along the tear line 3, as a result of which an opening for access 10 is formed and the sheath 36 is opened. Through the access hole 10, not shown in FIG. 5, a user may take one or more smoking tobacco products 8 from a packet P.

By means of component 15, the sheath 36 can be re-closed after the user has taken the smoking tobacco product 8 from the packet P. As mentioned above, component 15 can be put back in place and again adheres to the insulating sheet 1 in the region that borders the opening for access 10. In the case of FIG. 5, the rest of the material of the insulating sheet 1, limited by the tear line 3, in the region 6 of the access opening 10 remains glued to the component 15, as a result of which the upper ends of the smoking tobacco products 8 are protected from sticking to the component 15.

After closing the sheath 36 with component 15, the protective environment is restored for group C of smoking tobacco products 8 or, if one smoking tobacco product 8 was taken from packet P, for the residue of group C. Thus, the residue of group C can be protected for a long time from harmful external influences, and its taste and quality are preserved. In other words, the protection of group C or its residue from changes in aroma and freshness is restored. It should be said that component 15 can be used to repeatedly open and re-close the shell 36.

The transparency of component 15 and in the case of FIG. 5 also of the insulating sheet 1 allows the user to see the remainder of group C from the outside after re-closing the sheath 36 of packet P. Thus, after he smoked one of the smoking tobacco products 8 and if he wants to smoke another of the smoking tobacco products 8, the user can determine how many smoking tobacco products 8 remain in the pack without opening the sheath 36 for this. This has a positive effect

- 8 032373 on the convenience of handling the resealable packet P and helps to avoid unnecessary opening of the casing 36, as a result of which the protective environment for smoking tobacco products 8 is better preserved. In FIG. 6 shows the packet P of FIG. 5 in perspective rear view.

In FIG. 7 and 8 show a resealable pack P according to a second embodiment of the invention. Pack P of FIG. 7 and 8 includes a group C of smoking tobacco products 8, which are enclosed in a protective sheath 36 formed by the insulating sheet 1 of FIG. 3 and 4 and the corresponding component 15 of the valve type.

In the second embodiment of FIG. 7, 8, the insulating sheet 1, opaque or opaque, is located around group C and is closed at the seams 28 and 29, as a result of which the insulating sheet 1 and component 15 together form a sealed protective sheath 36 for group C of smoking tobacco products 8. As said in connection with FIG. 3 and 4, in the insulating sheet 1 of the packet of FIG. 7 and 8, an opening is made for access 10, which covers component 15 in the closed or re-closed state of packet P. Component 15 is adapted to be lifted from the insulating sheet 1, for example, starting from its edge 15a, to open the shell 36 in order to take one or several smoking tobacco products 8 through the access hole 10. After that, the shell 36 can be tightly closed using component 15.

In the embodiment of FIG. 7 and 8, the first part 16 of component 15 forms a transparent window. The valve-type component 15 extends along the leading upper edge 44 and the trailing upper edge 45 of the packet P. The window formed by the first part 16a is dimensioned to extend along the leading upper edge 44, but ends at the trailing upper edge 45. Of course, this is only an example , and the size of the window formed by the first part 16a may be selected different depending on the need. A window 16a bounded by an opaque or opaque edge formed by the second part 16b allows the user to see group C or its residue in the initial closed state of the sheath 36, as well as in its re-closed state.

Thus, although the insulating sheet 1 in FIG. 7 and 8 are opaque and can be completely opaque, the user can still determine or at least evaluate in the re-closed state of the sheath 36 how many smoking tobacco products 8 remain in the pack without opening the sheath 36 by lifting component 15. Thus, the taste and quality of smoking tobacco products 8 are better preserved.

Although the resealable packs P of FIG. 5, 6, as well as 7, 8 can be sold to the user as they are shown in these drawings, other embodiments are possible.

In FIG. 9 and 10 show a resealable pack according to a third embodiment of the invention, which includes a group C of smoking tobacco products 8 enclosed in an airtight protective sheath 36, as said with reference to FIG. 7 and 8, wherein the pack includes an opaque or light-tight insulation sheet 1. Furthermore, the pack P of FIG. 9 and 10 includes an external support frame 55, which in the case of the third embodiment is located outside the shell 36 and covers a relatively large part of the group C enclosed in the shell 36. As shown in FIG. 9, the upper edge 56 of the outer supporting frame 55 does not completely extend to the upper end 46 of the tobacco products C. Therefore, the inner pack formed by the group C enclosed in the sheath 36 protrudes from the outer supporting frame 55 at its upper end. Since the frame 55 does not close the component 15 and, importantly, does not close the access hole 10, the frame 55 can increase the mechanical stability of the packet P without hindering user access to smoking tobacco products 8. For convenient opening of the sheath 36, the frame 55 can be equipped with a recess 57, which can be adapted to the shape of the component 15 and / or to the shape of the access hole 10. If desired, the frame 55 can be glued to the sheath 36.

Any packs P in accordance with the first, second or third embodiments may also have enhanced protection, including, in addition, a soft outer wrap 66 of flexible sheet material. This is schematically shown in FIG. 11. The outer wrapper 66 may be provided with means suitable for opening it, for example, an exhaust thread or a tear-off valve, which are not shown in the drawings. Outer wrap 66 may optionally be overprinted. In the case of FIG. 11 any packs P of FIG. 5-10 can form a resealable inner pack enclosed in an outer wrapper 66.

A fourth preferred embodiment of the invention is shown in FIG. 12-15. Group C of smoking tobacco products 8 is enclosed in a sealed protective sheath 36, which is described above in connection with FIG. 5 and 6. However, the packet P of FIG. 12 and 13 is different from the packet P of FIG. 5 and 6 in that the pack P further includes an internal support frame 78, which further enhances the mechanical stability of the pack. The inner support frame 78 is located inside the sheath 36 between the part of the group C and the part of the sheath 36. In the case of the embodiment shown in FIG. 12 and 13, the frame 78 partially covers the front face or the main side of the group C, and the side flaps 77 partially cover the sides of the group C. A cutout area 76 can be made between the side flaps 77. The lower surface of the group C is closed by the end valve 79 of the internal support frame 78. As can also be understood from FIG. 12-15, upper surface T of group C, located

- 9 032373 laid opposite the bottom surface of group C, closed by an end valve 79, in this example, not covered by any part of the frame 78.

In the example of FIG. 12-15, the inner support frame 78 is further provided with a recess 80. An example of a blank 91 for forming the internal support frame 78 is shown in FIG. 14. The side flaps and end valve 79 are connected by folding lines to the main panel 75. The main panel 75 includes a recess 80.

As shown in FIG. 15, the preform 91 can be folded around a group C of smoking tobacco products 8 to form an internal support frame 78. Finally, to obtain the packet P of FIG. 12 and 13, frame 78 and group C of FIG. 15 is wrapped with insulating sheet 1, as described above in connection with FIG. 1 and 2, which are then sealed at the seams 28 and 29. Thus, the insulating sheet 1 and the valve top component 15 form an airtight protective cover 36 for smoking tobacco products 8.

The recess 80 is preferably made so that the tear line 3 of the insulating sheet 1 (see FIG. 12), which is provided for forming the access hole 10, and the area 6 of the access hole 10 to be formed, are not covered by the internal support frame from the inner space of the shell 36. This facilitates the removal of one or more smoking tobacco products 8 from the pack P after the shell 36 is opened.

Now with reference to FIG. 16-20, a fifth preferred embodiment will be described. The resealable pack P according to the fifth embodiment is shown in FIG. 16 in the closed state. The resealable bundle P according to this embodiment includes a rigid outer casing 100. The rigid outer casing 100 is designed as a hinged lid casing having a main body 101 and a lid 103 connected to the main body 101 via an inflection line 106. As can be seen in FIG. 16, the rigid outer casing 100 in this example has a substantially rectangular parallelepiped shape with rounded vertical corners.

In FIG. 17 shows a pack P according to a first embodiment of a fifth embodiment with an open lid 103. Inside the outer case 100 there is a resealable inner pack formed by a group C of smoking tobacco products 8 enclosed in an airtight protective sheath 36 consisting of an insulating sheet 1 and component 15 like sheaths shown and described with reference to FIG. 3 and 4. Group C of smoking tobacco products 8 may be located inside the casing 36 without an inner frame, for example as shown in FIG. 7 and 8, and there may also not be an external support frame for a group C enclosed in a sheath 36. However, the internal support frame 78, which is described above, or the external support frame 55, which is described above, can also be used in the case of the fifth embodiment .

In the embodiment of FIG. 17, the valve-shaped component 15 has a first portion 16a that is configured as a translucent window allowing the user to see at least some of the smoking tobacco products 8 in the sheath 36. The degree of transparency of the first portion 16a in the embodiment of FIG. 17 is less than the degree of transparency that would correspond to a fully transparent window. The second part 16b of the component 15 forms an opaque or opaque edge around the window 16a.

In the embodiment of FIG. 18, which otherwise corresponds to the embodiment of FIG. 17, the first part 16a, forming a window that provides visual access to the interior of the shell 36, is completely transparent and not translucent with a reduced degree of transparency.

In addition, according to a third embodiment of this embodiment shown in FIG. 19, which otherwise corresponds to the embodiment of FIG. 17, the first part 16 of component 15 is completely transparent, but in the case of FIG. 19, the transparent portion 16a is imprinted. As an example, comments and information for the user can be printed on the transparent part 16a, for example in the form of text 110. An ornament can also be printed on the component 15 in part 16a. Moreover, means for enhancing the effect of the window can be placed on the transparent part 16A as an overprint. This is shown in FIG. 19 is an example of highlighting a frame 115, which enhances the perception of printed text 110 and a transparent window 16a.

In one embodiment, the outer casing 100 may be semi-rigid rather than completely rigid. The outer casing 100 may be made of a suitable blank of cardboard or thick paper.

As can be understood, the packet P of FIG. 16-20 is preferable in that it provides additional protection for smoking tobacco products 8, in particular against mechanical stress, by the outer casing 100. In particular, the hinged lid 103 provides protection for the valve-type component 15. At the same time, however, the smoking tobacco products 8 in the packet P are placed in a protective environment, whereby the taste and quality of the smoking tobacco products 8 can be maintained. Since the component 15 has a transparent or translucent window-shaped portion 16a that allows the user to see at least partially, group C of smoking tobacco products 8 inside packet P and which makes it possible to see in a re-closed state of the casing 36 how many smoking tobacco products 8 remain, unnecessary opening of the casing 36 can be avoided. Ec and the lid 103 is closed, you should only open it to visually check whether the smoking of tobacco products 8 enough left in the pack. It should be said that, as specifically shown in FIG. 17-19, pack P

- 10 032373 also has an improved appearance. Typed text 110 may draw user attention to useful information.

The pack P according to the embodiment of FIG. 18 is also shown in different views in FIG. 20. Specifically, in FIG. 20b is a front view; FIG. 20a and c show a left view and a right view, respectively, in FIG. 20ά is a rear view, in FIG. 20e shows a bottom view and in FIG. £ 20 is a top view. On all types of a- £, the hinged lid 103 is in the open state.

Although the invention has been fully described above with reference to preferred embodiments, it is not limited to them and can be modified in various ways.

For example, the invention is not limited to packaging cigarettes, such as filter cigarettes, but can also be used to pack cigars or cigarillos.

The number of smoking tobacco products that make up the group may vary. The pack of the invention may contain, for example, 19 or 20 smoking tobacco products. However, in other embodiments, the number of smoking tobacco products contained in the pack may be more or less.

In addition, the invention can be used not only with an outer case with a hinged lid, such as the outer case 100, but other types of outer cases can be provided instead.
