Description

DESCRIPTION

of the industrial invention entitled: "Packaging of smoking articles of the rigid type with tilting opening."

TECHNIQUE SECTOR

The present invention relates to a rigid type packaging of smoking articles. In particular, the present invention relates to a package of smoking articles with an improved tilt opening.

In the following description, the smoking articles consist of a group of cigarettes wrapped in an internal wrapper, generally made of foil, without thereby losing generality.

ANTERIOR ART

The most popular cigarette packets are of the rigid type as they offer considerable protection to the contents against external stresses.

These packages are obtained starting from a pre-weakened and pre-cut flat blank that creates a container and are of the type with a lid hinged along a rear edge of the open end of the container itself. Furthermore, a collar is partially arranged inside the container to protrude from the open end so as to constitute an engagement element of the lid in its closed position.

To improve the closure of the package and keep the contents adequately protected, preserving the aroma and humidity, rigid packages with sliding or tilting opening are also known. These include at least two containers inserted one inside the other in such a way as to be able to distance each other without detachment. At least one inner container encloses a group of cigarettes and is held within an outer container. The internal container is movable with respect to the external container between an internal position, in which the internal container is arranged substantially completely within the external container, closing it, and a second external position, in which the internal container is arranged at least partially outside the container. external.

Known packages of the above types are described, for example, in documents EP2173625 and EP2017198.

The known solutions, however, have considerable disadvantages as regards the movement of the internal container with respect to the external container. In particular, when the internal container is hinged to the external container for the tilting of the same, the characteristic parallelepiped shape of the containers obliges to provide a considerable separation distance, or gap, between the upper walls of the same when the package is closed. This separation distance is obtained simply by providing that the internal container has a longitudinal extension, i.e. in the direction of development of the cigarettes it contains, which is less than the same extension as the external container. This negatively affects both the aesthetic appearance and the qualitative characteristics of the package in use. The light deriving from the different longitudinal extension of the two containers generates in fact a considerable internal play between them which arouses an impression of a defect on the consumer, a defect comparable to the laughing package (resulting from the imprecise closure) in hinged lid type packages. The play between the containers also compromises the mechanical stability of the package and the stability of the couplings, in particular of the coupling between the external container and the lid which the internal container is fitted with.

It would therefore be desirable to have a package of smoking articles, in particular cigarettes, capable of minimizing the drawbacks described above. In particular, it would be desirable to have a pack of smoking items that presents improved usability for the user.

It would also be desirable to have a pack of smoking items that has improved functionality in tilting operations.

Finally, it would be desirable to have a package of smoking articles which has a pleasant aesthetic appearance.

DESCRIPTION OF THE INVENTION

The object of the present invention is to provide a package of smoking articles with tilting opening which is capable of solving the aforementioned drawbacks, associating the improved functional characteristics with a pleasant aesthetic appearance.

In particular, the object of the present invention is to provide a package of smoking articles of the rigid type with tilting opening with a conformation of the internal container such as to reduce the difference in longitudinal extension with respect to the external container which holds it.

The aforementioned purposes are achieved by a package of smoking articles, in particular cigarettes, of the rigid type with tilting opening in accordance with the attached claims. The package includes:

- a group of smoking articles;

- at least one internal container of substantially parallelepiped shape with an open end and with a hinged lid, suitable for enclosing the group of smoking articles; - an external container of substantially parallelepiped shape with an open face provided with an external upper edge in correspondence with the upper wall, the external container is able to retain the internal container;

- a connection hinge between the internal container and the external container;

the lid comprises at least a head wall and a rear wall, mutually connected in a connecting portion, and is adapted to rotate between a closed position and an open position of the first open end;

the internal container is able to rotate around the connection hinge between an internal position, in which the internal container is arranged substantially completely within the external container, closing the open face, and an external position, in which the internal container is arranged at least partially outside the outer container at the open face;

the package is characterized by the fact that the internal container includes a first larger front wall that completely closes the open face when the internal container is in the internal position, the lid is shaped to allow the rotation of the internal container from the internal position to the position outside without interfering with the upper wall.

The greater front wall, which closes the open face of the external container, can therefore be extended longitudinally up to the upper external edge of the external container, minimizing the gap from the upper wall of the same external container. The lid can therefore extend from the main front wall and conform in such a way as to prevent the head wall of the lid from intersecting the upper wall of the outer container during the rotation of the inner container. Preferably, the package comprises coupling means suitable for coupling the head wall with the upper wall to automatically arrange the lid in the open position when the internal container is arranged in the external position, the lid profile is at least partially inscribed on the circumference hypothetical with center in the connection hinge and with a radius equal to the distance between the connection hinge and the coupling means provided on the external container.

In this way, the lid can be shaped as desired within the available area defined by the hypothetical circumference without the head wall of the same hindering the rotation of the internal container, up to the desired position for coupling the lid with the external container.

Preferably, the connection portion is a fillet or a chamfer to allow the rotation of the inner container from the internal position to the external position without interfering with the upper wall. Even more preferably, at least a portion of the fillet or chamfer is inscribed or superimposed on a portion of the hypothetical circumference.

The fillet or bevel allows the lid to be shaped in such a way as to maintain the head wall, visible to the consumer when the internal container is in the external position, perpendicular to the remaining walls of the internal container while avoiding any connection edge with the rear wall can deform the upper wall of the outer container. The overlapping or inscription within the hypothetical circumference allows to maximize the area available for the conformation of the lid.

Preferably, the head wall is inclined between a higher height position, corresponding to the open face, and a lower height position, corresponding to the connecting portion; the inclination of the head wall is suitable for allowing the rotation of the internal container from the internal position to the external position without overlapping the upper wall.

The inclination of the head wall makes it possible to couple a larger front wall with maximum extension with a back wall with a smaller extension. This allows, therefore, to preserve the aesthetic appearance of the package, when the internal container is in the internal position, and at the same time obtain a rotation without interference, to arrange the internal container in the external position.

Preferably, the external container comprises a pair of longitudinal walls and the internal container comprises a pair of lateral walls corresponding to the longitudinal walls; the package further comprises stop means in correspondence with at least one of the longitudinal walls and at least one of the corresponding side walls, the stop means are adapted to limit the rotation and the exit of the inner container from the open face when the inner container is ̈ rotated from the internal position to the external position.

Preferably, the external container comprises a lower wall provided with an external edge corresponding to the open face and the internal container comprises a bottom wall corresponding to the lower wall; the connection hinge between the internal container and the external container is obtained by overlapping the external edge on the back wall.

Preferably, the outer container comprises a larger rear wall and the inner container comprises a back wall; the main wall is provided with an access opening to the back wall to allow a user to arrange the internal container from the internal position to the external position.

Alternatively, the outer container comprises a larger rear wall and a larger front wall; the greater rear wall and / or the greater front wall are provided with gripping means to allow a user to arrange the internal container from the internal position to the external position.

The aforementioned purposes are further achieved by a package of smoking articles, in particular cigarettes, comprising:

- a first and a second groups of separate smoking articles;

- a first and a second internal containers of substantially parallelepiped shape, each respectively with a first and a second open end and with a first and second hinged lids, adapted to enclose the first and second smoking articles respectively;

PREFERRED EMBODIMENTS OF THE INVENTION With reference to Figures 1, 2A and 2B, a first embodiment of the package 1 of smoking articles, in particular cigarettes, according to the present invention is illustrated.

Pack 1 of cigarettes is of the rigid type with a substantially parallelepiped shape and tilting opening. In particular, the package 1 has a longitudinal extension, corresponding to the longitudinal axis A (illustrated in Figure 1), which develops in the direction of the symmetry axis of the cigarettes it contains. This longitudinal extension is the largest dimension of the package 1 itself. In the embodiment illustrated in the aforementioned figures, the package 1 comprises a first group of smoking articles made from a plurality of cigarettes wrapped in an internal envelope 2 of aluminum foil.

An internal container 3, also substantially parallelepiped in shape, encloses the group of cigarettes. Figure 3 illustrates the blank 3â € ™ suitable for defining the aforementioned internal container 3, the component parts of which are indicated below with the same reference numbers. The internal container 3 is provided with four longitudinal parallel walls two by two, in particular a greater front wall 33 and a back wall 63, parallel and opposite, connected to each other by a pair of side walls 13, 43, also ™ they are parallel and opposite. The internal container 3 is closed at one end by a bottom wall 53 and has, in the opposite position, an open end suitable for withdrawing and discharging the cigarettes. The closure of the aforesaid open end is ensured by a lid 23 hinged to the back wall 63 along a hinge line 9 transversal to the aforesaid longitudinal axis A. In particular, the lid 23 is able to rotate, with respect to the hinge line 9 transversal, between a closed position and an open position of the open end, allowing access to the group of cigarettes.

The lid 23 comprises a head wall 123 and a rear wall 223, respectively parallel and opposite to the bottom wall 53 and to the major front wall 33, when the aforementioned lid is in the closed position. These are mutually connected in a connecting portion 323. Furthermore, the lid 23 comprises two parallel and opposite side walls 423, 523, coplanar with the respective side walls 13, 43 of the internal container 3. In the closed position, the free edges of the side walls 423, 523 and of the head wall 123 are arranged in contact respectively with the free edges of the side walls 13, 43 and of the larger front wall 33 of the inner container 3.

The package 1 also comprises an external container 4 which is also substantially parallelepiped in shape. In the embodiment illustrated in Figures 1-3, the external container is defined by a larger rear wall 64 integral, along its perimeter, with a pair of longitudinal, parallel and opposite walls 44, and with a pair of upper walls 24 and lower 54, which are also parallel and opposite.

The outer container 4 is devoid of the opposite wall to the larger rear wall 64 where, instead, an open face 14 of the same is made. An outer upper edge 114 is provided at the open face 14 and the upper wall 24. Likewise, an outer lower edge 154 is provided in correspondence with the same open face 14 and the lower wall 54. The recess defined by the aforementioned open face 14 circumscribes a containment compartment for the internal container 3. The depth of the outer container 4 is defined by the width of the upper 24, lower 54 and longitudinal 44 walls and is substantially equal to the width of the corresponding walls of the inner container 3. The external container 4 is therefore capable of retaining the internal container 3 substantially completely, when this is arranged in an internal position. In particular, the rear greater 64, longitudinal 44, lower 54 and upper 24 walls of the outer container 4 are arranged substantially in contact respectively with the back 63, lateral 13, 43 and bottom 53 walls of the inner container 3 and with the wall 123 at the head of the relative lid 23, when the internal container 3 is arranged in the aforesaid internal position.

To allow a user to arrange the internal container 3 from the internal position to the external position, the larger wall 64 of the external container 4 is also provided with an opening for accessing the back wall 63 of the internal container 3 (not shown ). Preferably, this access opening is made by removing a circular portion of the larger wall 64 in correspondence with the area below the lid 23. The opening could be made on a different wall of the external container 4, for example on the lower wall 54 if the open face 14 were provided in correspondence with the upper wall 24. The same opening could also be shaped according to different conformations. In alternative embodiments, not shown, the outer container can comprise a major rear wall and a major front wall, as illustrated in EP2017198. In this case, the access opening can be replaced by gripping means, on one or both walls, to allow a user to arrange the internal container from the internal position to the external position. The gripping means therefore allow the two containers to be grasped and removed in order to automatically open the lid.

Furthermore, between the upper wall 24 of the external container 4 and the head wall 123 of the lid 23 are provided with coupling means suitable for mutually coupling the aforesaid walls to arrange the lid 23 in the open position. In particular, the hooking means allow the lid 23 to be automatically arranged in the open position while the internal container 3 is moved towards the external position.

The aforesaid coupling means comprise a tab 27 provided on the lid 23 and a slot (not shown) provided on the upper wall 24 of the external container 4. The tab 27 is defined by a notch 27 'made on the head wall 123 in such a way that it extends from the portion 323 for connection with the bottom wall 223, where it is hinged. The slot, on the other hand, is defined on the internal surface of the upper wall 24, in contact with the head wall 123 of the lid. This is obtained by means of a matching flap obtained on the aforesaid surface and by making an opening on the flap itself corresponding at least to the width of the tab 27 which it is intended to accommodate. The opening creates a pocket of suitable dimensions between the upper wall 24 and the internal flap of the same.

Different coupling means can also be provided according to the shape of the package and its elements with the aim of obtaining the operative coupling between the external container 4 and the lid 23.

The internal container 3 is hinged to the external container 4 at a connection hinge 5. In particular, in the embodiment illustrated in Figures 1-3, the connection hinge 5 is obtained by superimposing the outer edge 154 of the outer container 4 on the bottom wall 53 of the inner container 3 at the respective outer edge 153. In different embodiments, not shown, the outer edge 154 of the outer container 4 could be superimposed on the bottom wall 53 of the inner container 3 in a spaced position with respect to the outer edge 153. In this case, the connection hinge 5 would be obtained overlapping the bottom wall 53 of the internal container 3, for example in a median position.

The internal container 3 is able to rotate around the aforementioned hinge 5 for connection between an internal position (illustrated in Figure 2A), in which it is arranged substantially completely within the external container 4, closing its open face 14, and a second external position (illustrated in Figure 2B), in which it is arranged partially outside the external container 4 in correspondence with the same open face 14. In order to allow the rotation of the internal container 3 from the internal position to the external position without interfering with the upper wall 24 of the external container 4, the lid 23 is suitably shaped. In particular, the conformation is defined, in the embodiment illustrated in Figures 1-3, by the connecting portion. The latter consists of a connection 323 of the head 123 and bottom walls 223 of the lid 23. This connection 323 prevents the rotation of the container 3 from causing the portion 323 itself to interfere with the upper wall 24 of the outer lid 4 , as instead illustrated in Figure 4 where the projection of the edge R, if it were thus realized, would deform the upper wall 24 or the walls constituting the lid 23 itself.

To avoid the rotation of the inner container 3 being hindered by the outer container 4, the area of a plane of the cross section of the inner container 3, as shown in the sections and views of Figures 1-2B, can be used during its rotation It is defined by a hypothetical circumference whose center is the hinge 5 connecting the two internal 3 and external 4 containers. This hypothetical circumference is a geometric construction designed to define a flat area on which the side walls 13, 43 of the internal container 3 and the lateral walls 423, 523 of the lid 23, or sections of the plane coplanar to these, can rotate without interference with the external container 4 around the connection hinge 5.

The overall dimensions of the internal container 3 is critical in correspondence with the lid 23, in particular when the latter is moved together with the container 3 itself, keeping it in its closed position until the coupling means previously described are coupled.

The maximum space allowed for the internal container 3 during rotation around the connection hinge 5 is therefore defined by the aforementioned hypothetical circumference. In particular, in order to exploit the maximum extension, and volume, of the internal container 3, minimizing the difference in longitudinal extension with respect to the external container 4 which holds it, at least one point of the profile of the lid 23 must belong to the aforementioned hypothetical circumference. Therefore, the profile of the lid 23 must be at least partially inscribed in the hypothetical circumference which has its center in the connection hinge 5 and a radius equal to the distance between it and the coupling means, in particular of the portion of the coupling means belonging to the upper wall 24 of the 4 external container. This is because, the coupling of the tab 27 with the slot allows the lid 23 to be hinged also in a second hinge, defined precisely by the coupling between the coupling means, causing a relative movement between the lid 23 and the internal container 3 for automatically arranging the aforementioned lid 23 in the open position.

The hypothetical circumference seca the head 123 and bottom 223 walls, if these were coupled with a sharp edge R as shown in Figure 4, in at least one point each. The arc of circumference between the two intersection points identifies the maximum perimeter within which it is possible to create the connection portion 323. In the embodiment illustrated in Figures 1-3, the fillet constituting the connection portion 323 has a fillet radius equal to the radius of the hypothetical circumference, extending to the maximum the admissible size of the internal container 3 since the fitting 323 is superimposed or parallel to the hypothetical circumference. In this way, the longitudinal extension of the internal container 3 is slightly less than the same extension of the external container 4.

Furthermore, stop means are provided between the longitudinal walls 44 of the external container 4 and the side walls 13, 43 of the internal container 3. These are adapted to limit the rotation and the escape of the internal container 3 from the open face 14 of the external container 4 when the internal container 3 is rotated from the internal position (Figure 2A) to the external position (Figure 2B). The end-of-stroke means therefore allow to predetermine the amplitude of rotation of the internal container 3 around the connection hinge 5.

The aforesaid end-of-stroke means comprise, relative to each of the side walls 13, 43, a tab 113, 143, defined by a notch, which extends from its end towards the greater front wall 33. The tongues 113, 143 are designed to engage with a suitably shaped edge of an abutment flap (not shown) obtained on each of the internal surfaces of the corresponding longitudinal walls 44.

Different stop means can be further provided according to the shape of the package and its elements with the aim of obtaining a limitation of the rotation of the internal container 3 with respect to the external container 4.

The package 1 is initially arranged with the internal container 3 in the internal position, in contact with the external container 4 and, consequently, with the lid 23 in the closed position. A user can therefore arrange the internal container 3 from the internal position to the external position by acting on the circular opening made on the largest wall 64 of the external container 4. The opening allows access to the back of the internal container 3 which can be removed by exerting pressure on it. The internal container 3 can therefore be moved up to the external position by imparting a pressure to it which allows it to rotate with respect to the external container 4 around the connection hinge 5. The rotation of the internal container 3 proceeds by dragging the corresponding lid 23, connected to it along the transversal hinge 9 on the back wall 63. The conformation of the fitting 323 allows to drag the lid avoiding that the head wall 123 interferes with the upper wall 24 causing probable deformations and / or breakages. When the hooking means of the two containers 3, 4 are close, the tab 27 provided on the end wall 123 is inserted into the appropriate slot in the corresponding upper wall 24. The reciprocal coupling generates a second hinge line 27 for the lid 23 which is constrained and free to rotate around two axes. The first line of hinge 9 allows rotation with respect to the internal container 3 which closes. The second line of hinge 27â € ™ â € ™ allows rotation with respect to the external container 4 when the internal container is rotated to be placed in the external position.

The coupling of the coupling means also allows the lid 23 to be automatically arranged in the open position, allowing access to the group of cigarettes automatically. A second embodiment of the package 6 is illustrated in Figures 5A-5B. This has characteristics similar to the package 1 described above and therefore only the different parts will be described below.

Also for this embodiment the principle is valid that the maximum space allowed for the internal container 8 during rotation around the connection hinge 7 is defined by the hypothetical circumference. In particular, in order to exploit the maximum extension of the internal container 8, minimizing the difference in longitudinal extension with respect to the external container 9 which holds it, at least one point of the profile of the lid 28 must belong to the aforementioned hypothetical circumference.

The profile of the lid 28 must be at least partially inscribed on the hypothetical circumference which has its center in the connection hinge 7 and a radius equal to the distance between it and the coupling means (not shown) placed on the head wall 25 of the external container 9.

The hypothetical circumference seca the head 128 and the bottom 228 walls in at least one point each. The arc of circumference between the two points of intersection identifies the maximum perimeter within which it is possible to create the connection portion 328. In the embodiment illustrated in the aforementioned figures, the connecting portion is made by means of a chamfer which joins the two points separated by the hypothetical circumference. The chamfer 328 is therefore entirely inscribed within the hypothetical circumference, the initial and final points of the segment forming it being part of it. Alternatively, at least one of the two points can be inside the area defined by the hypothetical circumference. Also in this embodiment the longitudinal extension of the internal container 8 is slightly less than the same extension of the external container 9.

The opening and access to the group of cigarettes in pack 6 is the same as previously described for pack 1 to which reference is made.

A third embodiment for the inner container is illustrated in the blank 11â € ™ of Figure 6. In this embodiment the head wall 121 is inclined between a position at a greater height, in correspondence with the open face of the outer container, and a lower height position, in correspondence with the connecting portion 321. The latter is made simply by means of an edge that joins the top wall 121 with the back wall 221. The inclination of the head wall 121 is suitable for allowing the rotation of the internal container 3 from the internal position to the external position without interfering with the upper wall of the external container.

As for the embodiments described above, the maximum allowable space requirement for the inner container during rotation around the connecting hinge is defined by the hypothetical circumference.

To maximize the overall dimensions of the internal container, while allowing rotation without interference, the corner 321 which defines the position at a lower height of the head wall 121 must be a point of the hypothetical circumference. The inscription within the hypothetical circumference guarantees that the rotation takes place without deformation or friction between the two containers.

Also in this embodiment the longitudinal extension of the internal container will be slightly less than the same extension of the external container.

A further embodiment, not shown, relates to a package provided with two internal containers enclosed by a single external container. A package of this type is, for example, described in EP2017198.

First and second groups of separate smoking articles are contained within first and second internal containers having a substantially parallelepiped shape. Access to the groups of cigarettes is ensured by the open ends and the relative lids, hinged to the aforementioned first and second internal containers.

The external container, which is also substantially parallelepiped in shape and is suitable for retaining the aforementioned internal containers, is provided with two opposite open faces and suitable for the partial release of the aforementioned internal containers. Each of the two open faces is provided with external upper edges in correspondence with the upper wall.

First and second connection hinges respectively constrain the first and second internal containers to the body of the external container, allowing the internal containers to rotate relative to the same. In particular, the rotation around the aforementioned connection hinges involves the movement of the internal containers from an internal position, in which they are arranged substantially completely within the external container, closing the open faces, to an external position, in which they are arranged at least partially outside the external container with open faces.

Each of the internal containers comprises a minor front wall which completely closes the corresponding open face when the internal containers are placed in the internal position.

The movement of the internal containers up to the external position is obtained by keeping the lid in the closed position. Therefore, even in this case it is necessary that the lids are shaped to allow the rotation of the internal containers from the internal position to the external position without interfering with the upper wall of the external container.

The conformation of the lid can be realized according to one or more of the variants provided in the previous embodiments. In particular, the lids of the internal containers comprise a connection portion between the head wall and the rear wall which can be of the rounded or blunt type. In addition or alternatively, the head wall can be inclined between a higher height position, corresponding to the open face, and a lower height position, corresponding to the connection portion. In this case, the inclination of the head wall allows the rotation of the internal container from the internal position to the external position without interfering with the upper wall.

To ensure that the conformation of the aforementioned lids is such as to avoid interference in rotation between them and the external container, each of the lids, and in particular of the connection portions, must be inscribed, at least partially, at the relative hypothetical circumference with center in the connection hinge between the respective internal container and the external container and with a radius equal to the distance from said hinge to the respective coupling means for the lids provided on the external container.

The advantages obtained by means of a package according to the present invention therefore relate to the improved access to the group of cigarettes and to the improved conformation and coupling between the containers which constitute it. The conformation of the connection portion and / or of the head wall allows to improve the interaction between the internal and external container, avoiding opening difficulties due to the interference between the internal container, in particular in the portion constituted by the lid, and the upper wall of the outer container. Furthermore, arranging the conformation of the lid in accordance with the present invention allows the realization of a larger front wall of the internal container of extension substantially equal to the open face of the external container, minimizing the separation distance from the upper wall of the external container.

A further advantage achieved by the present invention relates to the saving of material which can be obtained by reducing the size of the lid to be inscribed within the hypothetical circumference. This saving is possible both with the realization of a rounded or chamfered connection portion and with an inclined head wall, as previously described for the preferred embodiments.

Furthermore, although the aforesaid description and attached figures relate to packages comprising an external container and one or more internal containers of the hinged lid type, in which both the external and internal containers are provided with sharp edges, it is obvious that the teachings of the present invention can be applied to any type of external and internal container, which can provide, according to embodiments not shown, one or more longitudinal and / or transversal rounded or beveled edges. For example, the longitudinal edges could be non-straight edges, but of a rounded or blunt type, or (taking the shape of the cigarette packet described in patent application EP0764595A1) the major transversal edges could be non-straight edges, but of a rounded or blunt. Alternatively, some longitudinal edges and some transversal edges could be non-straight edges, but of a rounded type so as to have the presence of both longitudinal edges and transversal edges that are not straight, but of a rounded or blunt type.
