Description

Sliding lid pack.

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

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

An unwanted phenomenon of cover packages articulated, 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, increased exposure to oxygen or air of the contents or an increased loss of flavor.

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 that have "ears" on the edges of the side walls of the collar or a snap mechanism on 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.

GB 961 5558 discloses a package with a lid pivotally connected where the front cover wall and walls cover sides extend outwards from the walls corresponding part of the package part so that the lid can slide over the pack part.

An object of the present invention consists in provide innovative and improved packages that reduce or avoid inconveniences of the articulated lid package.

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

In particular the invention includes two subgroups, that is:

one.

A package comprising a first part and a second part, the which parts are connected to each other, where both parts are they can move linearly with respect to each other from a closed position to an open position, and vice versa, and where the first part is a receptacle and the second part is a lid and the receptacle and lid are connected to each other by means of connection, preferably a tongue, which is fixed to or apart from a lid and that can be moved inside the receptacle

characterized by the fact that the lid, when closed and the receptacle is join together along an individual coupling line well defined and that the free edges of the first part border the opposite free edges of the second part.

2.

A package comprising a first part and a second part, the which parts are connected to each other, where both parts are they can move linearly with respect to each other from a closed position to an open position, and vice versa, and where the first part is a receptacle and the second part is a lid and the receptacle and lid are connected to each other by connecting means through a tongue or other connection means, which is fixed to or apart from the receptacle and that can be moved inside the top

characterized by the fact that the lid, when closed and the receptacle is join together along an individual coupling line well defined and that the free edges of the first part border the opposite free edges of the second part.

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

The receptacle is the part of the package that can keep the items in the package, which is the article or items They will be packed. The receptacle comprises a bottom wall (which is at the same time the bottom wall of the package) and at minus a receptacle wall that joins the bottom wall. The Bottom wall can present various shapes. For example, if the Bottom wall is circular or oval, conveniently there is only one receptacle wall that joins the lower circular or oval wall, along its circumference. If the bottom wall is essentially rectangular (or square) - including such walls bottom 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 small size For example, the front wall may be missing or have a reduced size and / or one or both side walls can have a small size, so that the sides of the receptacle do not They are completely covered by the side walls. Yes the wall lower is polygonal (for example octagonal) can be distinguished at most a corresponding number of receptacle walls (per example, at most a total of eight receptacle walls in case octagonal bottom wall). For example, in the case of packages with beveled edges, the receptacle can be formed from a octagonal bottom wall with a front wall, a back wall and two side walls and the four receptacle walls remaining being formed by the beveled edges of the wall front, back wall and side walls. In general, the bottom and receptacle walls are preferably adapted the to each other, so that a receptacle wall is provided or receptacle walls that correspond to the shape of the wall lower, and one or more may be missing, but not the maximum of all possible receptacle walls. So, you get a enclosure closed at the bottom and at least partially closed in its lateral parts. The top of the receptacle (which is oriented towards the lid) is at least partially, and preferably, completely open. So, the wall bottom of the receptacle is in front of the top of the receptacle at least partially open. Further, preferably the receptacle walls are perpendicular to the bottom wall. It is particularly preferred that the receptacle Understand an internal structure or collar.

The second part, referred alternatively as the cover part of the package of the invention comprises a wall top (which is at the same time the top wall of the package) and at least one cover wall attached to said upper wall. Wall upper and the wall or lid walls preferably adapt the to each other so that a cover wall or walls of lid corresponding to the shape of the upper wall. May be missing one or more, but not all lid walls, to the fullest. Wall or lid walls fit the top wall, so that the lid resulting is closed at the top and at least partially closed in its lateral parts. The bottom of the lid (the which goes to the receptacle) is at least partial and preferably, completely open. So the top wall of the lid is placed in front of the bottom of the lid at less partially open. Preferably, the cover wall or lid walls are perpendicular to the upper wall. By example, a lid with an essentially rectangular top wall (or square) 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 edges between the four Walls can be round.

The two parts of the package, the receptacle and the lid, preferably have corresponding open sides. He receptacle and lid thus provide each one with a space. With the closure of the package, these two spaces are united in a single space. This allows items present in the package, in position open, be kept only in the receptacle and extend longer beyond the receptacle inside the lid in the closed position. For example, this applies in case the package content It consists of elongated items, such as cigarettes.

Preferably, the first part (receptacle) and the second part (lid) of the package of the present invention, is connect with each other so that under regular conditions and of planned handling, the two parts do not separate the one from the another when the package is completely open. The conditions Planned handling includes repeated openings and closures of the package until all items contained are finished. The connection of the two parts is essentially permanent in nature and is not damaged or destroyed adversely during the package opening. You can get that connection essentially permanent, for example, by applying an adhesive, such as a glue, to fix the appropriate connection means to the receptacle walls, lid or both. As an alternative, the connection between the receptacle part and the lid part can be established, for example, through mechanical means. The connection it is generally achieved through one or more connection means suitable, which connect the receptacle with the cover, by example a thread, a tape, a strand, a filament, a flap, a tongue or a tongue-shaped part (successively referred to together as a tongue) or any combination thereof. A Particularly preferred connection means is a tongue. Bliss tongue can be an integral part of receptacle, lid, or a separate part. In the latter case one end of the tongue joins typically to one of the two parts of the package, for example when 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 manufactured in 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 it manufactures the lid. Optionally the tongue can be folded, by Z folded example. Preferably, the tongue has a leaf type structure. Which means that it is relatively thin and its width substantially corresponds to, or is more smaller than the width of the receptacle wall or the wall of lid, in particular is smaller than the back wall of the receptacle or that the back wall of the lid. The tongue is designed in such a way that sufficient rigidity can be obtained during opening and closing of the package, particularly when the tongue moves up and down between the wall rear of the receptacle and the contents of the package.

The packages lack articulation, which means that the lid part and the receptacle part are not connected along an articulated line, as is the case with a conventional articulated lid package. Rather, the packages of the present invention are characterized by the fact that the two parts can move continuously in a linear motion relative to each other 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.

It is preferred that the package in position closed do not have any open side. The adjacent open sides of the receptacle and the lid adapt to each other. In position closed the two parts of the packages of the present invention are butt together against each other, meaning that the free edges of the lid part butt against opposite edges, edges correspondingly of the receptacle along the line of clip art. Said coupling line can be designed to take any desired shape, and can be straight, in waveform, curve, rectangular or triangular, or any combination of these. It is also possible that one or more wall or lid walls and / or one or more wall or receptacle walls have A cut portion. These trimmed portions are found in corresponding and matching positions of the lid wall and the receptacle wall, and have corresponding shapes (for example each one can have the shape of a semicircle). Portions cropped (for example in the form of a circle formed by two semicircles) can facilitate the opening of the package.

In some prior art packages the lid portion is disposed on the receptacle portion of the package to get a closed package. In other words, the cover It is folded as a telescope over the receptacle. How consequently, edges around at least three or more are obtained surfaces of said packages. In contrast to the above, the Closed packages of the invention do not exhibit any or only one flange. In other words, with the closing of the packages moving the cover linearly towards the receptacle, these two parts are joined with each other along an interface or line of correspondence properly defined. The lid part and of receptacle of prior art packages, join the one with the other along the interface or coupling surfaces, because the lid slides at least partially over the receptacle.

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

The packages provide additional advantages, which they include, for example, an increased surface area in the open position, compared to an articulated lid package conventional. Such increased surface area can be useful, for example, for communication or information purposes at consumer. Additionally, the packages make it easier to hold the content or aroma preservation within the package. Too combine the known stiffness of articulated lid packages, with the advantage of handling known soft packs.

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

Preferably, the packages of the invention They have the shape 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 packages of cigarettes where cigarettes line up parallel to the axis longitudinal of the packages.

In a first subgroup, the invention provides packages where the receptacle and lid connect to each other through any suitable connection means that is fixed to, or is 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 tongue connection function.

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

The 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 back wall of the cover (for example an integral extension or a fixed extension with respect to the rear wall of the inner cover), which extends beyond the lower cover edge and within 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.

As mentioned earlier, the tongue it can be fixed only to one part, or it can be a component integral of this, for example, the lid. The connection to the second part, for example the receptacle, which is necessary to avoid the accidental separation of the two parts of the package, for example, during the opening process, it is generated during the movement linear, properly 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 back wall of the receptacle part, where the wall is parallel to the tongue and it’s close to it. It is important that the first and second flaps are adjusted so as to allow interaction between them. From properly, the flaps and the interaction between them are designed such that these limit the extent of linear motion of The opening. For example, the first and second flaps can bend in opposite directions, for example, inwards and towards outside, resulting in the embedded interaction or interdigitation

A flap can be an integral part or separate from the tongue, or a wall. In case the flap is an integral part, this can be built by bending outwards or inward a small part of the free edge of the wall, or of the tongue As an alternative, a flap can be built 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 wall posterior, or tongue. Preferably, the flap is made in The same material as the package. However, you can also use other suitable materials such as plastics, metals, or laminates The flap can be attached or fixed to the wall or the tongue

The first and second flaps can have the Same form or a different form. Preferably, a flap, for example the wall flap, can have a rectangular shape, and the another flap, for example the tongue flap, may have a conical triangle or semicircle shape. Are also possible other shapes such as crest or wavy structures. The use of the first and second flaps formed in a manner Different can improve your ability to interact. For example, the flap on the rear wall of the receptacle can have a rectangular shape, and the flap of the tongue can have the shape of a semicircle.

When you open the package, the lid moves linearly moving away from the receptacle until the flap of the tab and the back wall flap snap together. This is the final opening position. An advantage of this package is that it does not additional connection means, such as wires, are needed, strips, strands, or filaments to provide the connection between the lid and the receptacle Another advantage is greater flexibility in design of the package. For example, as the receptacle part and the part of lid have been made from two different models, can be Produce separately and can be manufactured in materials different.

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 tongue length difference in folded condition and not bent Alternatively and / or additionally, the tongue can be fixed to the receptacle by one or more connection means, such as fine threads, allowing a degree of movement that essentially determined by the length of the thread or threads and the tongue length In another alternative, the tongue has a width less than the inner part of the rear wall of the receptacle, and has one or two sided sideburns. The receptacle has a bump or bumps corresponding, which are directed towards the walls side of the receptacle and in the line of motion of the tongue. When the lid, pin or tongue pins are opened come into contact with the bump or bumps of the receptacle, and stop the opening movement.

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

The packages lack a joint. Without However, when folding, folding or turning the lid away from the direction of linear opening, you can bend or break the back wall of the cover or extension of the back wall due to these movements. A designated bending line can also be provided. on the back of the lid or on the wall extension posterior to ensure that a folding or folding always occurs along the same designated line.

Preferably, the packages according to first subgroup have an internal structure or a collar attached to the internal part of the receptacle extending from the receptacle until inside the lid in the closed position. That provision It has the advantage of providing more protection and retention of 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 be extend through the front wall, through the walls left and right sides and at least partially from the side walls through the back wall of the package. For the that, you can get two back wall extensions of the collar, one on each side of the back wall and adjacent to the walls Left and right collar sides. The extensions, in turn each can be divided into a top and bottom flap, with a flap (the bottom one) completely arranged inside the receptacle, and a flap (the upper one) arranged only partially inside the receptacle.

A particularly preferred package according to the The present invention is obtained by combining this type of collar with a parallelepiped receptacle and a suitable lid that it has an integrated or joined tongue, said tongue being equipped with a flap at its fixed end (see detailed description of this tab mode later). The advantage of this combination is that the back wall extensions of the collar they provide a secure guide of the tongue, since the lower part of the tongue is arranged between the collar extension flaps bottoms and the rear wall of the receptacle, and that the wall upper tongue is arranged between the extension flaps of the top collar and the contents of the package. So, a tongue side is in contact with the extension flaps of the lower back wall of the collar, and the other side of the tongue is in contact with the wall extension flaps Rear upper collar. This alternate contact produces a safe guide of the lid during the opening and closure made by the consumer, and supports movements without turning of the lid with respect to the receptacle.

Another particularly preferred package according to the invention is a parallelepiped package comprising a part of receptacle 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 end that extends into the receptacle, which flap fits the internal structure on the back wall of the receptacle, thus providing the connection between the two parts of the package.

Preferably, the packages according to first preferred subgroup have the shape of a parallelepiped rectangular, where the edges of the lid located opposite the receptacle on the sides corresponding to the opening form the minus one cropped portion and preferably two portions trimmed on opposite sides, for example on the back side and the front side The trimmed portion or portions may have various shapes, such as circles, semicircles, triangles and in particular isosceles triangles. The edges of the receptacle that orient towards the lid on the open sides of correspondence, they form a counterpart with, and match, a cutting part corresponding cover that is oriented in the receptacle. Preferably, the two counterparts on opposite sides will be couple with the trimmed portions and have the shape of a isosceles triangle or triangles. These packages have the advantage that the consumer, regardless of whether he is left or right handed, You can hold the package with your left or right hand, and the thumb, and more preferably also with the index finger in case of two portions cut, in both cases located in the counterpart or Receptacle counterparts in the form of a triangle or isosceles triangles, in an ideal position so that you can hold Package very tightly and open it easily.

As a second subgroup, the invention provides packages where the receptacle and lid connect to each other through a suitable connection means, which is fixed to, or is a integral part of the receptacle. The connection means is as it is defined above, in relation to the first subgroup. Without However, for the second subgroup packages, it is preferred that the connecting means is a tongue that is part of, or is identical to the rear wall of the receptacle, optionally in combination with one or more threads.

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 small size (for example in a semicircle or triangle) of such that they do not completely cover (extend along) the side or sides of the receptacle. The cover comprises a wall top, a back wall, a front wall and at least one, preferably two side walls. Preferably the wall Lower and upper wall have a rectangular shape. Wall or side walls may have a reduced size (for example with portions cut in the shape of a semicircle or triangle), of such that they do not completely cover the side or sides of the lid, but correspond to the reduced wall or side walls of the receptacle. So, when the package is in the closed position, all sides close completely due to the combination of (appropriate) adjustment of partial receptacle side walls and of the partial lid side walls.

The result of the opening movement is that the cover 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 full length in the opening, to be able to easily remove these cigarettes from the package. This It has the advantage of being able to easily access the products.

In a second embodiment of the second subgroup, the receptacle comprises a rear wall, a wall bottom (preferably rectangular), at least two walls laterals and a front wall. One or more of the walls may have a small size For example one of the side walls, the front wall and the back wall are small in size, it is say that they have trimmed portions, for example in the form of square, semicircle or triangle, so that you are walls do not completely cover the respective side or sides, but Only part of them. The trimmed portions are placed in adjacent parts of the walls. The cover comprises a wall upper (preferably rectangular), a back wall, a front wall and at least two side walls. One of the walls sides, the front wall and the back wall have a size reduced, that is to say that they have portions cut in shape, by example, of square, semicircle or triangle. Portions clipped are placed in adjacent parts of the walls, so that do not completely cover the respective side or sides, but that correspond essentially to the portions cut in the receptacle. So, when the package is closed, all sides close completely due to the combination of fit (coupling) of the partial receptacle walls with the partial cover walls.

Subsequently said package has a lid that in the open position it 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 package items. The advantage of this is that, due to the relatively small opening, the risk of the Content accidentally falls out of the package.

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 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 opening movement
linear.

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

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

Particularly preferred packages where the tongue attaches 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 towards outside, and where the receptacle comprises a flap, which flap it is an integral part of the back of the receptacle and it performed by folding the upper edge of the back wall back inside the space defined by the walls of the receptacle. These specific packages also include a folding line designed in the extension of the rear wall of the lid (which you should also consider as a part of the tab that is an integral part of the lid) so that the lid can be rotated precisely along the line of creased. These embodiments provide all the advantages in Comparison with soft or articulated lid technique packages above, including an increased surface area, a content retention and improved aroma preservation, excellent handling properties, good stability and production facility

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 paper or laminated, cardboard, plastic, wood, for example softwood, velvet, velvet, leather and / or metal type materials, being the paper and cardboard preferred. Materials are selected so that meet the desired properties of the package.

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 so that the first and second are formed parts with their respective front walls, back walls, side walls, upper walls and lower walls (always that are all present). For materials that cannot be bent, the respective walls are properly joined between yes, for example by gluing, so that some are obtained again First and second separate parts. These are then connected between yes by appropriate connection means, for example through the use of an adhesive or a thread to produce the final packages.

Similar parts in the figures are designated by similar numbers.

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

Figure 2 shows a cross section of the pack of cigarettes 10 along the line ll-ll. You can see the upper wall 28, the wall bottom 38 and the rear walls 26 and 36 and a tongue 21, the which is fixed with an adhesive to the inside of the wall back cover 26, which has extensions, so that 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 end bottom by a thread 23 to the bottom wall 38, for example by small drops of adhesive on the tongue 21 and the bottom wall 38. The length of the thread 23 defines the distance at which the cover 20 can be moved or exited from receptacle 30. Figure 2 shows also front walls 22 and 32 and a collar 40 which is also made of cardboard and that sticks to the inside of the front wall of the receptacle 32. The collar 40 usually extends, such as is shown in figure 2, beyond receptacle 30, and in the closed position of the package 10, inside the lid 20 and along of the front wall of the receptacle 32 and the side walls of the receptacle 34.
