DESCRIPTION

Sliding lid pack

[0001] The invention relates to packs in general, and in particular to packages (or packs) for tobacco products, such as elongated smoking articles.

[0002] A type of package normally very popular for tobacco products, and also for other items, such as food or candy products, is the package called "flip-top" or articulated lid. Said package is characterized by a box part comprising the items to be packaged and an articulated lid part at the end of the back of the box. Normally, said package has an internal structure inside the box part, which extends upwards from the box part to the inside of the lid part when the latter is opened and closed.

[0003] An unwanted phenomenon of articulated lid packages is the "smile effect", which reveals a space between the box part and the lid part and prevents complete closure of the package. This effect is not desirable because it may imply, for example, an accidental loss of the contents of the package, an increased exposure to oxygen or air of the contents or an increased loss of flavor.

[0004] There are many proposals in the prior art that are intended to reduce the "smile effect". For example, EP 204 933 B1 and EP 205 766 B1 describe articulated lid packages with round or beveled longitudinal edges having "ears" on the edges of the side walls of the collar or a mechanism for engaging the front wall; EP 650 907 B1 describes articulated cover packages where the side walls of the collar are formed such that increased friction is obtained with the side walls of the cover.

[0005] GB 961 5558 discloses a package with a pivotally connected cover where the front cover wall and the cover side walls extend outward from the corresponding walls of the package part so that the cover can slide over the pack part.

[0006] An object of the present invention is to provide novel and improved packages that reduce or avoid the inconveniences of the articulated lid package.

[0007] The present invention provides packages according to claims 1 and 12.

[0008] In particular the invention includes two subgroups, that is:

one.

A package comprising a first part and a second part, which parts are connected to each other, where both parts can move linearly with respect to each other from a closed position to an open position, and vice versa, and where the The first part is a receptacle and the second part is a lid and the receptacle and the lid are connected to each other by means of connection, preferably a tongue, which is fixed to or part of a lid and which can be moved inside the receptacle characterized by the the fact that the lid, when closed and the receptacle, are joined together along a well-defined individual coupling line and that the free edges of the first part collide with the opposite free edges of the second part.

2.

A package comprising a first part and a second part, which parts are connected to each other, where both parts can move linearly with respect to each other from a closed position to an open position, and vice versa, and where the The first part is a receptacle and the second part is a lid and the receptacle and the lid are connected to each other by means of connection through a tongue or other connection means, which is fixed to or part of the receptacle and which can be moved inside of the lid characterized by the fact that the lid, when closed and the receptacle are joined together along a well-defined individual coupling line and that the free edges of the first part collide with the opposite free edges of the second part.

[0009] The first part or part of the box is the receptacle and the second part is the lid.

[0010] The receptacle is the part of the package that can hold the items in the package, which is the item or items that will be packaged. The receptacle comprises a bottom wall (which is at the same time the bottom wall of the package) and at least one receptacle wall that joins the bottom wall. The bottom wall can have several shapes. For example, if the bottom wall is circular or oval, conveniently there is only one receptacle wall that joins the bottom circular or oval wall, along its circumference. If the bottom wall is essentially rectangular (or square) - including such bottom walls with one, two, three, or four round corners - there are a maximum of four distinguishable receptacle walls, that is, a front wall, a back wall and two side walls . The edges between said walls can be optionally round or beveled. However, one or more of the walls may be missing and / or have a reduced size. For example, the front wall may be missing

or have a reduced size and / or one or both side walls may have a reduced size, so that the

Receptacle sides are not fully covered by the side walls. If the bottom wall is polygonal (for example octagonal), a corresponding number of receptacle walls can be distinguished at most (for example, a maximum of eight receptacle walls in the case of an octagonal bottom wall). For example, in the case of packages with beveled edges, the receptacle can be formed from an octagonal bottom wall with a front wall, a back wall and two side walls and the remaining four receptacle walls being formed by the beveled edges of the front wall, the back wall and the side walls. In general, the bottom and receptacle walls are preferably adapted to each other, so that a receptacle wall or receptacle walls corresponding to the shape of the bottom wall are provided, and one or more may be missing, but not the maximum of all possible receptacle walls. Therefore, a closed receptacle is obtained in the lower part and at least partially closed in its lateral parts. The upper part of the receptacle (which is oriented towards the lid) is at least partially, and preferably, completely open. Therefore, the bottom wall of the receptacle is in front of the upper part of the receptacle at least partially open. In addition, preferably the receptacle walls are perpendicular to the bottom wall. It is particularly preferred that the receptacle comprises an internal structure or a collar.

[0011] The second part, alternatively referred to as the cover part of the package of the invention, comprises an upper wall (which is at the same time the upper wall of the package) and at least one cover wall attached to said upper wall. The upper wall and the wall or cover walls are preferably adapted to each other so that a cover wall or cover walls corresponding to the shape of the upper wall is provided. One or more may be missing, but not all cover walls, to the fullest. The cover wall or walls are adapted to the upper wall, so that the resulting cover is closed at the top and at least partially closed at its side parts. The lower part of the lid (which is directed towards the receptacle) is at least partially and preferably completely open. So the top wall of the lid is located in front of the bottom of the lid at least partially open. Preferably, the lid wall or lid walls are perpendicular to the upper wall. For example, a cover with an essentially rectangular (or square) top wall is combined with a front wall, a back wall and two side walls - preferably at least one and even more preferably more than one or all of the edges between the four walls can be round

[0012] The two parts of the package, the receptacle and the lid, preferably have corresponding open sides. The receptacle and lid thus provide each one with a space. With the closure of the package, these two spaces come together in a single space. This allows the items present in the package, in the open position, to be held only in the receptacle and extended beyond the receptacle into the lid in the closed position. For example, this applies in case the contents of the package consist of elongated items, such as cigarettes.

[0013] Preferably, the first part (receptacle) and the second part (lid) of the package of the present invention are connected to each other so that under regular and expected handling conditions, the two parts do not separate from each other. another when the package is completely open. Expected handling conditions include repeated openings and closures of the package until all contained items are finished. The connection of the two parts is essentially permanent in nature and is not damaged or destroyed adversely during the opening of the package. Said essentially permanent connection can be obtained, for example, by applying an adhesive, such as a glue, to fix the appropriate connection means to the walls of the receptacle, lid or both. Alternatively, the connection between the receptacle part and the lid part can be established, for example, by mechanical means. The connection is generally achieved through one or more suitable connection means, which connect the receptacle with the cover, for example a thread, a tape, a strand, a filament, a flap, a tongue or a part in the form of tongue (successively referred to together as tongue) or any combination thereof. A particularly preferred connection means is a tongue. Said tongue can be an integral part of the receptacle, lid, or a separate part. In the latter case, one end of the tongue is typically attached to one of the two parts of the package, for example to the receptacle, and the other end of the tongue is fixed to the other part of the package, for example to the lid. Suitably, the tongue is made of the same material as the package, for example the materials mentioned below, such as cardboard and paper. The tongue may or may not be part of the same piece with which the lid is manufactured. Optionally the tongue can be folded, for example folded in the form of z. Preferably, the tongue has a sheet-like structure. Which means that it is relatively thin and its width substantially corresponds to, or is smaller than, the width of the receptacle wall or the lid wall, in particular it is smaller than the rear wall of the receptacle or that the rear wall of the top. The tongue is designed in such a way that sufficient rigidity can be obtained during the opening and closing of the package, in particular when the tongue moves up and down between the rear wall of the receptacle and the contents of the package.

[0014] The packages lack articulation, which means that the cover part and the receptacle part are not connected along an articulated line, as is the case with a conventional articulated cover package. Rather, the packages of the present invention are characterized by the fact that the two parts can move continuously in a linear motion in relation to one another between the open position and the closed position (and not as in the case of a joint, in a circular motion). This linear movement can also be described as a drawer movement.

[0015] It is preferred that the package in the closed position has no open side. The adjacent open sides of the receptacle and the lid adapt to each other. In the closed position the two parts of the packages of the present invention are butt joined against each other, that is to say that the free edges of the lid part are butt joined against the opposite edges, correspondingly shaped edges of the receptacle along the pre-designed coupling line. Said coupling line can be designed to adopt any desired shape, and can be straight, waveform, curved, rectangular or triangular, or any combination thereof. It is also possible that one or more wall or lid walls and / or one or more wall or receptacle walls have a clipped portion. Said trimmed portions are in corresponding and coincident positions of the lid wall and the receptacle wall, and have corresponding shapes (for example each can have the shape of a semicircle). The trimmed portions (for example in the form of a circle formed by two semicircles) can facilitate the opening of the package.

[0016] In some prior art packages the lid portion is disposed on the receptacle portion of the package to obtain a closed package. In other words, the lid is folded as a telescope over the receptacle. As a consequence, edges are obtained around at least three or more surfaces of said packages. In contrast to the above, the closed packages of the invention do not exhibit any or only a flange. In other words, with the closure of the packages moving the lid linearly towards the receptacle, these two parts are joined to each other along a properly defined interface or correspondence line. The lid and receptacle part of the prior art packages are joined to each other along the interface or coupling surfaces, because the lid slides at least partially over the receptacle.

[0017] As mentioned above, the receptacle wall or walls and the cover wall or walls are preferably perpendicular to the lower (receptacle) wall or the upper (cover) wall. Furthermore, it is preferred that the shape of the bottom wall and the top wall be adapted to each other and have corresponding geometric shapes, so that the resulting package preferably has the shape of a rectangular parallelepiped (in the case of lower walls and rectangular top, with or without round or beveled corners) or the shape of a cylinder (in the case of round and oval bottom and top walls). However, it may also be that the receptacle and lid walls are not perpendicular to the lower or upper walls, respectively. In this case, the resulting package can be in the form of a pyramid for example (with a lower square receptacle wall and an upper lid wall reduced to a single point) or the truncated cone shape (with a rectangular rectangular bottom wall and a top wall with a rectangular but smaller lid). In this case, preferably the package has a constant cross-section along the distance of the linear movement.

[0018] The packages provide additional advantages, including, for example, an increased surface area in the open position, as compared to a conventional articulated lid package. Such increased surface area may be useful, for example, for communication or consumer information purposes. Additionally, the packages facilitate the subjection of the content or the preservation of the aroma within the package. They also combine the known stiffness of articulated lid packages, with the advantage of handling known soft packages.

[0019] The present invention relates to the packages themselves, as well as to packages loaded with content. Although they are generally useful for various types of articles, the new packages of the invention are particularly useful for tobacco products, for example elongated smoking articles, preferably cigarettes. The size and shape of the packages are chosen so as to properly place the intended content. For example, the size of cigarette packages can be chosen to place for example, 10, 20, or 25 cigarettes.

[0020] Preferably, the packages of the invention are in the form of a rectangular parallelepiped. Optionally, one or more, preferably all (longitudinal) edges of the packages of the present invention can be beveled or round. Particularly preferred packages of the invention are cigarette packages where the cigarettes are aligned parallel to the longitudinal axis of the packages.

[0021] In a first subgroup, the invention provides packages where the receptacle and the lid are connected to each other through any suitable connection means that is fixed to, or is an integral part of the lid and that can be moved inside the receptacle . Preferably, such means of connection is a tongue. If desired, additional connection means may be present to support the connection function of the tongue.

[0022] To access the contents of the package, the consumer can open the packages with a continuous and linear (or sliding) movement of the separate cover of the receptacle. To close the package, the lid moves towards the receptacle.

[0023] Separation of the receptacle lid can be prevented by the presence of one or more connection means. Preferably, the medium is fixed on the lid or even part of it and can be moved inside the receptacle. Advantageously, the connection means are fixed on one of the inner sides of the cover. To prevent the separation of the two parts of the package when opening the package, the connection means, such as the tongue, can also be attached to the receptacle properly. For example, a suitable way to fix the connection means to the receptacle is by mechanical interaction, such as the fitting of a flap at the lower end of the tongue with one or more means, with one or more suitable receptacle counterparts. In particular, the tongue can be an extension of the wall

rear of the lid (for example an integral extension or a fixed extension with respect to the rear wall of the inner lid), which extends beyond the lower lid edge and into a receptacle (in closed and open positions). Advantageously, the tongue has a sheet-like shape that is substantially the same width as the inner side of the rear wall of the receptacle. Therefore, the tongue is guided on one side by the rear wall of the receptacle, and on the other side by the contents of the package. The tongue can be fixed to the rear wall of the receptacle, in particular, to the edge formed by the rear wall of the receptacle and the bottom wall. This allows a defined extension of linear motion that is essentially determined by the length of the tongue.

[0024] As mentioned above, the tongue can be fixed only to one part, or it can be an integral component of it, for example, the cover. The connection to the second part, for example the receptacle, which is necessary to prevent accidental separation of the two parts of the package, for example, during the opening process, is generated during the linear movement, suitably during the opening process. For example, the tongue, which is fixed to the lid may comprise a first flap at its non-fixed end, which first flap interacts with one or more second flap or flaps included in the rear wall of the receptacle part, where the Wall is parallel to the tongue and is close to it. It is important that the first and second flaps are adjusted to allow interaction between them. Suitably, the flaps and the interaction between them are designed such that they limit the extent of linear movement of the opening. For example, the first and second flaps can bend in opposite directions, for example, inwardly and outwardly, resulting in the engagement of interlock or interdigitation.

[0025] A flap can be an integral or separate part of the tongue, or a wall. In case the flap is an integral part, it can be constructed by folding a small part of the free edge of the wall, or the tongue, outward or inward. As an alternative, a flap can be constructed by attaching an additional element to the wall or to the tongue. The additional element may extend over part, or over the entire width of the wall, preferably of the back wall, or of the tongue. Preferably, the flap is made of the same material as the package. However, other suitable materials such as plastics, metals, or laminates can also be used. The flap can be glued or fixed to the wall or the tongue.

[0026] The first and second flaps may have the same or a different shape. Preferably, a flap, for example the wall flap, can have a rectangular shape, and the other flap, for example the tongue flap, can have a conical triangle or semicircle shape. Other shapes such as crest or wavy structures are also possible. The use of the first and second flaps formed differently can improve your ability to interact. For example, the flap on the rear wall of the receptacle may have a rectangular shape, and the flap on the tongue may have the shape of a semicircle.

[0027] When opening the package, the lid moves linearly away from the receptacle until the flap of the tongue and the flap of the rear wall are fitted. This is the final opening position. An advantage of such a package is that no additional connection means, such as wires, strips, strands, or filaments are needed to provide the connection between the lid and the receptacle. Another advantage is greater flexibility in package design. For example, since the receptacle part and the lid part have been made from two different models, they can be produced separately and can be manufactured in different materials.

[0028] The tongue can be optionally bent. Then, it can be fixed to the inner part of the receptacle, preferably to the bottom or front walls of the receptacle. The degree of movement is then determined by the difference in length of the tongue in folded and unfolded condition. Alternatively and / or additionally, the tongue can be fixed to the receptacle by one or more connection means, such as thin wires, allowing a degree of movement that is essentially determined by the length of the wire or wires and the length of the tongue. In another alternative, the tongue has a width smaller than the inner part of the rear wall of the receptacle, and has one or two side-facing pins. The receptacle has a corresponding protuberance or protuberances, which are directed towards the side walls of the receptacle and in the line of movement of the tongue. When the lid is opened, the tongue pin or pins come into contact with the protuberance or protuberances of the receptacle, and stop the opening movement.

[0029] For packages where the connection means is a tongue, it is particularly preferred that the degree of movement possible is such that in the fully open position or in the maximum opening position the lid is sufficiently far from the receptacle (or outside the receptacle) so that it can be folded or turned away from the linear opening direction. This has the advantage of being able to access the contents of the package more easily.

[0030] Packages lack an articulation. However, by folding, folding or turning the cover away from the direction of linear opening, the back wall of the cover or the extension of the back wall can be curved or broken due to these movements. A designated bending line can also be provided on the back of the cover or on the extension of the back wall to ensure that a bending or folding along the same designated line always occurs.

[0031] Preferably, the packages according to the first subgroup have an internal structure or a collar attached to the internal part of the receptacle that extends from the receptacle into the lid in the closed position.

Such provision has the advantage of providing more protection and retention of the package content. In addition, the internal structure can provide a guide during the opening and closing movements of the lid. It is particularly preferred that the internal structure and the collar extend through the front wall, through the left and right side walls and at least partially from the side walls through the back wall of the package. Therefore, two extensions of the rear wall of the collar can be obtained, one on each side of the rear wall and adjacent to the left and right side walls of the collar. The extensions, in turn, can each be divided into an upper and a lower flap, with a flap (the lower one) completely arranged inside the receptacle, and a flap (the upper one) arranged only partially inside the receptacle.

[0032] A particularly preferred package according to the present invention is obtained by combining this type of collar with a parallelepiped receptacle and a suitable cover having an integrated or attached tongue, said tongue being equipped with a flap at its fixed end (see the detailed description of this tongue mode later). The advantage of this combination is that the rear wall extensions of the collar provide a secure guide of the tongue, since the lower part of the tongue is disposed between the lower collar extension flaps and the rear wall of the receptacle, and that the Upper tongue wall is disposed between the upper collar extension flaps and the contents of the package. Therefore, one side of the tongue is in contact with the lower rear wall extension flaps of the collar, and the other side of the tongue is in contact with the upper rear wall extension flaps of the collar. This alternating contact produces a secure guide of the lid during the opening and closing movements made by the consumer, and supports movements without turning the lid with respect to the receptacle.

[0033] Another particularly preferred package according to the invention is a parallelepiped package comprising a receptacle part with an internal structure and a lid part, where the means of connection between the parts is a tongue that has a flap at the extending end. inside the receptacle, which flap fits the internal structure in the rear wall of the receptacle, thereby providing the connection between the two parts of the package.

[0034] Preferably, the packages according to the first preferred subgroup are in the form of a rectangular parallelepiped, where the edges of the lid facing the receptacle on the sides corresponding to the opening form at least one cut-out portion and preferably two cut-out portions on the opposite sides, for example on the back side and the front side. The cut-out portion or portions may have various shapes, such as circles, semicircles, triangles and in particular, isosceles triangles. The edges of the receptacle that face the lid on the open sides of the correspondence form a counterpart with, and coincide with, a corresponding cutting portion of the lid that is oriented in the receptacle. Preferably, the two counterparts on opposite sides are coupled with the cut out portions and have the shape of an isosceles triangle or triangles. These packages have the advantage that the consumer, regardless of whether he is left or right handed, can hold the package with his left or right hand, and his thumb, and more preferably also with his index finger in case of two cut portions, in both cases located in the counterpart or counterparts of the receptacle in the form of an isosceles triangle or triangles, in an ideal position so that the package can be held very firmly and easily opened.

[0035] As a second subgroup, the invention provides packages where the receptacle and the lid are connected to each other through a suitable connection means, which is fixed to, or is an integral part of the receptacle. The connection means is as defined above, in relation to the first subgroup. However, for the packages of the second subgroup, it is preferred that the connection means be a tongue that is part of, or is identical to the rear wall of the receptacle, optionally in combination with one or more wires.

[0036] In a first embodiment of this second subgroup, the receptacle comprises a rear wall, a bottom wall, at least one, preferably two side walls and no front wall. The wall or side walls may have a reduced size (for example in a semicircle or a triangle) such that they do not completely cover (extend along) the side or sides of the receptacle. The cover comprises an upper wall, a rear wall, a front wall and at least one, preferably two side walls. Preferably, the lower wall and the upper wall have a rectangular shape. The wall or side walls may have a reduced size (for example with portions cut in the shape of a semicircle or triangle), such that they do not completely cover the cover side or sides, but correspond to the reduced side wall or walls of the receptacle. Therefore, when the package is in the closed position, all sides are completely closed due to the combination of (appropriate) adjustment of the partial side walls of the receptacle and the partial side walls of the lid.

[0037] The result of the opening movement is that the lid partially overlaps in the open position with the receptacle. An opening is thus obtained in the front part of the package. For example, in the case of cigarette packages, said arrangement allows an opening on the front side of the package with one or more cigarettes placed along the entire length in the opening, in order to easily remove these cigarettes from the package. This has the advantage of being able to easily access the products of the.

[0038] In a second embodiment of the second subgroup, the receptacle comprises a rear wall, a bottom wall (preferably rectangular), at least two side walls and a front wall. One or more of the

fifteen

25

35

Four. Five

55

65

E04726979

11-12-2014

walls may have a reduced size. For example, one of the side walls, the front wall and the rear wall have a reduced size, that is to say they have cut-out portions, for example in the form of a square, a semicircle or a triangle, so that these walls do not completely cover the respective side or sides, but only a part of them. The trimmed portions are located in adjacent parts of the walls. The cover comprises an upper wall (preferably rectangular), a rear wall, a front wall and at least two side walls. One of the side walls, the front wall and the rear wall have a reduced size, that is to say they have portions cut in the form, for example, of a square, semicircle or triangle. The trimmed portions are located in adjacent parts of the walls, so that they do not completely cover the respective side or sides, but essentially correspond to the trimmed portions in the receptacle. Therefore, when the package is closed, all sides are completely closed due to the combination of fit (coupling) of the partial receptacle walls with the partial lid walls.

[0039] Subsequently said package has a lid that in the open position overlaps with the receptacle on two opposite sides. An opening is thus obtained on one of the sides of the package. This is another position for easy removal of items from the package. The advantage of this is that, due to the relatively small opening, the risk of the content accidentally falling out of the package is reduced.

[0040] The consumer can open said packages, according to the second subgroup, by a movement of the lid away from the receptacle or by closing the latter by means of a movement towards the receptacle. The separation of the receptacle lid can be avoided through the connection means that is fixed to the receptacle, or preferably, to certain parts or points of the receptacle, usually to one of the internal sides of the receptacle. The tongue can be an extension of, or preferably an integral part of the rear wall of the receptacle (whereby, an extension fixed to the inner rear wall of the receptacle or preferably a direct extension thereof), which extends into the lid in closed and open positions. The tongue (or rear wall of the receptacle) normally has a sheet shape that is essentially the same width and preferably also essentially the same height as the inner side of the rear wall of the lid, so that the rear wall of the lid and The rear wall of the receptacle is fully engaged in the closed position. Preferably, the tongue is fixed to the front wall of the lid, in particular, to the edge formed by the front wall of the lid and the upper wall. This allows a defined extension of the linear movement that is essentially determined by the length of the tongue. The tongue can be optionally bent. Subsequently, it can be fixed to the inner side of the lid, preferably, to the top or front lid walls. The extent of movement is subsequently determined through the difference in the length of the tongue in folded and unfolded condition. Alternatively and / or additionally, the tongue can be fixed to the cover by one or more connection means, such as thin wires, allowing an extension of the movement that is essentially defined by the length of the wire or wires and the length of the tongue. In another alternative, the tongue has a smaller width to the inner side of the back wall of the lid, and has one or two pins that are directed sideways. The lid has a corresponding protuberance or protuberances that are directed towards the side walls of the lid and in the line of movement of the tongue. When the lid is opened, the pin or pins of the tongue come into contact with the protuberance or protuberances of the lid and stop the opening movement. In another alternative, the tongue can be fixed only to a part of the package or be part of said part. This alternative has already been described above together with the embodiments of the first subgroup, and can be applied in a similar manner in this embodiment. Therefore, another possibility is to hold the connection means, for example the tongue, with the receptacle and control the extent of the linear opening movement.

[0041] In a particularly preferred embodiment of the second subgroup, the tongue is formed by the rear wall of the receptacle that engages completely with the rear wall of the lid. In this embodiment, the receptacle also comprises a bottom wall of the receptacle and one or two side walls of the receptacle (preferably in the form of an isosceles triangle or triangles), but without a front wall of the receptacle, in order to easily remove the items from the package.

[0042] It is preferred that the packages according to the second subgroup are in the form of a rectangular parallelepiped, where the edges of the lid facing the receptacle on the opening coupling sides, form at least one cut-out portion and preferably two cut-out portions in opposite sides, for example, on the sides of the lid. The cut-out portion or portions may have various shapes, such as circles, semicircles, triangles, and in particular isosceles triangles. The edges of the receptacle that are located in front of the lid on the sides of the coupling opening, form a counterpart of, and are coupled with the corresponding cut-out portion of the lid that are located in front of the receptacle. The two counterparts on opposite sides mate with the cut parts and preferably have the shape of an isosceles triangle or triangles. These packages have the advantage that the consumer, regardless of being left or right handed, can hold the package with his right or left hand, and with his thumb, and more preferably also with his index finger in case of two clipped portions, in both cases located in the counterpart or counterparts of the receptacle in the form of an isosceles triangle or triangles, that is to say in an ideal position so as to be able to hold the package very firmly and open it easily.

[0043] Particularly preferred packages where the tongue is attached to the lid, or is an integral part of the lid, and where the tongue flap is an integral part of the tongue, and is formed by folding the non-fixed end of the tongue out, and where the receptacle comprises a flap, which flap is an integral part of the rear part of the receptacle and is realized by folding the upper edge of the back wall back into the

space defined by the walls of the receptacle. These specific packages also include a folding line designed in the extension of the back wall of the lid (which should also be considered as a part of the tongue that is an integral part of the lid) so that the lid can be rotated from precise way along the folding line. These embodiments provide all the advantages compared to soft or articulated lid packages of prior art, including increased surface area, retention of content and improved aroma preservation, excellent handling properties, good stability and ease of handling. production.

[0044] These packages according to the invention can be made from various materials or combination of materials. Suitable materials are known in the art and include, for example, paper, for example, coated or laminated paper, cardboard, plastic, wood, for example softwood, velvet, velvet, leather and / or metal materials, the paper being and cardboard preferred. Materials are selected so that they meet the desired properties of the package.

[0045] The packages according to the invention can be made from separate models, for example, a model for the receptacle and a model for the lid. The models for each part are folded in such a way that the first and second parts are formed with their respective front walls, rear walls, side walls, upper walls and lower walls (provided they are all present). For materials that cannot be folded, the respective walls are suitably joined together, for example by gluing, so that first and second separate parts are obtained again. These are then connected to each other by suitable connection means, for example through the use of an adhesive or a wire to produce the final packages.

[0046] The invention is illustrated by the following figures, where:

-Figure 1 is a front side view of a pack of cigarettes 10 that exemplifies the first preferred subgroup in

the closed position.

- Figure 2 is a view of the cigarette pack 10 of Figure 1 along line II-II.

- Figure 6 is a view of a pack of cigarettes 10 similar to Figure 1 along line II-II.

-Figure 7 shows the design and location of a flap 90 on the tongue 21 of the package of Figure 6.

[0047] Similar parts in the figures are designated by similar numbers.

[0048] The closed cigarette pack 10 of Figure 1 made of regular cardboard has a lid 20 with a front wall 22, side walls 24, rear wall 26 and upper wall 28 and a receptacle 30, with a front wall 32, side walls 34, rear wall 36 and bottom wall 38. The receptacle 30 and the lid 20 are coupled along an interface line 50. The receptacle 30 is designed to hold a group of cigarettes, for example, 20 size cigarettes normal.

[0049] Figure 2 shows a cross section of the pack of cigarettes 10 along line II-II. The upper wall 28, the lower wall 38 and the rear walls 26 and 36 and a tongue 21 can be seen, which is fixed with an adhesive to the inner part of the rear wall of the lid 26, which has extensions, so which in the closed position, as in Figures 1 and 2, covers except a small space at the lower end of the rear wall of the receptacle 36, essentially all internal sides of the rear walls 26 and 36. The tongue 21 is connected to its lower end by a thread 23 to the lower wall 38, for example by small drops of adhesive on the tongue 21 and the lower wall 38. The length of the thread 23 defines the distance in which the cover 20 can move or exit the receptacle 30. Figure 2 also shows front walls 22 and 32 and a collar 40 which is also made of cardboard and which is glued to the inner part of the front wall of the receptacle 32. The collar 40 usually extends, as shown in the figure 2, beyond the receptacle 30, and in the closed position of the package 10, within the cover 20 and along the front wall of the receptacle 32 and the side walls of the receptacle 34. In this embodiment, the collar is not extends through the rear wall of the receptacle 36. Also shown is the coupling line 50 against which the receptacle part 30 and the lid part 20 are joined together.

[0050] Figure 3 shows the pack of cigarettes 10 (the cigarettes are not shown in figure 3) of figures 1 and 2, in the open position. The receptacle 30 and the cover 20 can be seen, as well as the collar 40 with its front wall 42 and its side walls 44. In addition, the tongue 21 and the collar 40 can be distinguished.

[0051] As can be seen in Figures 1, 2, and 3, the front wall of the cover 22 has a cut-off portion 25 in the shape of an isosceles triangle, with a coupling counterpart 35 in the receptacle 30 which It also has the shape of an isosceles triangle. The same isosceles coupling triangles can be provided on the cover 20 and the receptacle 30 on the back of the case, as can be seen from the cross section shown in Figure 2. The angle � is preferably approximately 90º.

[0052] As can be seen in Figures 1 and 3, the opening and closing can be easily realized by means of holding the receptacle 30 and arranging, for example, a thumb on the isosceles triangle 35 and pushing the cover for opening or by tightening the cover for closing.

[0053] Figure 4 refers to a different embodiment according to the invention, that is to say a pack of cigarettes 10 according to the first embodiment of the second subgroup. The cigarette pack 10 of Figure 4 is provided with the lid 20 with a front lid wall 22, side walls 24, upper wall 29 and rear wall 26. The receptacle 30 is also provided with its bottom wall 39 and its side walls 34. As can also be seen, a front wall of the receptacle is absent in the cigarette pack 10 of Figure 4, and the rear wall of the receptacle 36 is also at the same time the tongue extending into the interior of the lid 20.

[0054] The cigarette pack 10 of Figure 4 is in the open position and it can be seen that the consumer can, for opening and closing, hold the side walls of the receptacle 34 (both in the preferred form of an isosceles triangle ) with, for example, the thumb and index finger and the cover with the other hand so that the receptacle 30 and the cover 20 can then be moved away or towards each other. The cigarette pack 10 in Figure 4 is empty, but one can easily imagine that cigarettes wrapped in an inner liner can be attached to the interior of the receptacle 30. In case the use of an inner liner is undesirable, the walls The sides of the receptacle 34 can be designed differently so that complete side walls are formed, and if desired, also a complete upper wall. This way you can avoid the risk of cigarettes falling out of the package.

[0055] Figure 5 shows an example of the second embodiment of cigarette packs 10 according to the second subgroup with a lid portion 20 (with front wall of lid 22, upper wall of lid 29, rear wall of lid 26 and lid side walls 24) and receptacle 30 (with receptacle front wall 32, receptacle bottom walls 39, receptacle rear wall 36 and receptacle side walls 34. As for the other cigarette packages 10 shown, also the package 10 of Figure 5 may have the isosceles triangles on the lid 20. As can be seen in Figure 5, an opening 46 is formed on one side of the cigarette pack 10 which is relatively small compared to normal cigarette packets, of so that the risk of cigarettes accidentally falling out of the cigarette pack can be significantly reduced.

[0056] Figure 6 shows a cross section analogous to Figure 2 of the package similar to the package of Figure 1. The difference is the connection means. The tongue 21 comprises an integral flap 90 made by folding outwardly from the unsealed end or edge of the tongue 21. The rear wall of receptacle 36 comprises a flap 91 made by folding into the upper edge of the wall 36. Figure 7 it is a rear view of the cover 20 of the package of Figure 6. The cover 20 includes the rear wall 26 and the tongue 21 exposing the design of the flap 90 made by folding outwardly of the unsealed end of the tongue 21. curved edges of the flap 92, allow easy interaction with the rear wall flap of the receptacle 91.
