Description

"PACKAGE FOR CIGARETTES WITH A SLIDE OPENING, CORRESPONDING SET OF BLANKS AND METHOD FOR THE MANIFACTURING OF SAID PACKAGE"

DESCRIPTION

Field of application'

The present invention refers to a package, in particular to a package for cigarettes, of the type with a slide opening.

5 The invention also refers to a set of blanks necessary for forming the abovementioned package of cigarettes and to a method for the formation of said cigarette package on the basis of said blanks.

The invention has practical applications in particular in the tobacco industry.

10 Prior art

Cigarettes are traditionally packaged in rigid packages, substantially in the shape of a rectangular parallelepiped, with a lid on the top hinged along a weakened axis to allow access to the plurality of cigarettes contained therein.

15 Although traditional packages as described above largely respond to the needs of the field, over time there have been several proposals for alternative packaging, mainly to lend an innovative and original aspect to the product as an incentive to buy for the consumer.

Of the different variants that have been developed and 20 marketed, we mention in particular packages that substitute the traditional hinged opening with a sliding opening.

In a first type of package with slide opening there is an internal container that can be opened from above and that is slidably inserted into the external container. By laterally extracting the internal 25 container, the cigarettes it contains become accessible. This type of opening is not very widespread, though, partly because of the relatively high material costs due to having a double enclosure, but above all because the extraction of the whole of the internal container proves to be an awkward operation compared to the simple opening of the flip top of a traditional package.

An alternative solution for packages with slide opening is described in the American patent US 7,926,653, which describes a cigarette package according to the preamble of claim 1.

In said package the slidabte portion is limited to a top lid, which is closed on three sides but which has a lateral opening that allows it to slide reciprocally along the perimeter edges of the external container that forms the package.

The above described package presents a number of disadvantages, however. In particular the slide lid can easily be removed from the package, leaving the cigarettes inside accidentally accessible, with the resultant inconvenience for the consumer.

To resolve the disadvantage indicated above, one of the embodiments proposed by the abovementioned patent describes that the lid is supplied with two lateral tabs that depart from the two opposite lateral walls to join at the bottom to create a U-shaped appendix that slides, when the lid is operated, between an external boxlike enclosure and an internal boxlike enclosure.

One will note, however, that the appendix in question shows a relatively large extension; in fact, it runs along the entire height of the cigarette package. In order to maneuver the slide lid, therefore, one needs to overcome a significant amount of attrition, which makes the operation of opening and closing the package relatively hard.

Also as a result of the extension of the U-shaped appendix, there is a risk of the lid becoming stuck in situations of misalignment of the lid-appendix group with regard to the sliding direction.

As a final remark it is observed that there is also the risk of cuts and tears that would compromise the functionality of the U-shaped appendix.

The technical problem at the base of the present invention is therefore to design a cigarette package with a slide opening that resolves the drawbacks of the prior art as described above, and in particular that allows the alternating sliding of a top lid in a simple manner and without risks of detachment with respect to the main body of the package.

Summary of the invention

The abovementioned technical problem is resolved by a package, intended to contain a plurality of cigarettes, comprising:

- an external container, comprising at least two main lateral walls opposite each other, two secondary lateral walls opposite each other and a back wall intended to enclose said plurality of cigarettes, said external container having a top access opening to allow a consumer access to the cigarettes;

- and a slide lid associated above to the external container, comprising an upper wall and lateral walls intended to enclose an uppermost volume of said package, said lid presenting a lateral opening to allow a rectilinear movement of said slide lid between: a closing position, in which the slide lid obstructs the access opening of the external container; and an open position, in which it leaves the access opening open to make the cigarettes available;

wherein said external container includes an external bridge element that connects the two main lateral walls of the external container from above, embracing said slide lid in such a way that it forms a slide constraint for said slide lid.

A person skilled in the art will without difficulty recognize that the bridge element prevents the slide lid from becoming detached without having to include an elongated internal appendix in the lid itself.

The abovementioned bridge element can in particular comprise two lateral tabs that depart from the two main lateral walls of the external container and an upper portion that connects these two lateral tabs.

This U-shape conformation allows the entire vertical extension of the slide lid to be embraced, which, as mentioned above, has lateral walls with the purpose of enclosing the upper volume of the package.

The lateral walls of said slide lid can in particular comprise two main lateral walls that are opposite each other and a secondary lateral wall that is opposite the lateral opening.

One will note the importance of these lateral walls, in particular of the main lateral walls that allow there to be an access opening with lateral openings to facilitate taking the cigarettes. The lateral tabs can have a grip opening located in such a way that it allows access to the respective facing lateral wall of the slide lid.

Thanks to this solution the consumer can grip the end of the slide lid between his fingers, considerably augmenting the ease of operating the slide opening.

The grip openings are preferably in communication with a sliding window on a secondary lateral wall of the external container wherein the slide lid moves.

Also to be noted is the fact that the external bridge element is preferably located at a lateral end of the package. In particular said element is preferably located entirely on one half of the package, whereas on the other half of the package the previously defined access opening is located.

The previously defined main lateral walls can advantageously comprise a respective lip intended to come in abutment against an internal surface of a secondary lateral wall in order to limit the movement of the slide lid.

The lip can of course be substituted by blocking means of another kind.

The package according to the present invention can moreover comprise an internal frame placed inside the external container; said internal frame comprising an internal bridge element, said slide lid being slidably inserted in a gap between said internal bridge element and said external bridge element.

Thus the internal bridge element and the external bridge element can limit the movement of the slide lid in a direction that is transverse to the package.

The slide lid is in fact constrained in its movements along the gap between the two bridge elements. If the gap is sufficiently extended in a transverse direction, the whole of the two bridge elements constitutes an actual sliding guide, which not only impedes the slide lid from becoming detached, but also prevents rotation of the latter with respect to the sliding window of the external container.

One will note that the slide lid is easily slidable, basically placed between the bridge element of the internal frame and the bridge element of the external container.

In a first embodiment this internal frame may be entirely contained within the external container; in a second embodiment the internal frame may present some portions that project out of the external container to define structural elements of the package.

The internal frame may advantageously include walls or parts of walls that internally abut against the respective walls of the external container. The equivalence of the dimensions of these walls defines a stable position for the internal frame inside the external container, without necessitating spot gluing or any other kind of mechanical fixation systems.

The technical problem identified above is moreover resolved by a set of blanks for the formation of a package as defined previously. This set comprises at least: a first blank for forming the external container and a second blank for forming the slide lid; it may also comprise a third blank for forming the internal frame.

The technical problem identified above is moreover resolved by a method for the formation of a package of the kind previously defined on the basis of the abovementioned set of blanks. In particular the method comprises the steps of: forming the internal frame on the basis of the third blank; forming the slide lid on the basis of the second blank; placing the slide lid above the internal frame; forming the external container by folding and fixing the first blank in such a way as to enclose the internal frame and the slide lid placed above it.

Further characteristics and advantages will become clearer from the following detailed description of two preferred, but not exclusive, embodiments of the present invention, with reference to the enclosed figures by way of non-limiting examples.

Detailed description

With reference to the enclosed figures 1-7, the number 1 generically indicates a cigarette package according to a first embodiment of the present invention.

As can be seen in figure 7 the package contains a plurality of cigarettes (100) packaged in an internal paper wrapper 101 of the conventional type.

The internal wrapper 101 has been inserted in an external container 2, which substantially presents the shape of a rectangular parallelepiped, even though it has two openings in the upper part that will be described in detail below. The height H of the external container 2 is substantially equal to the height of the internal wrapper 101 , in other words to the height of the cigarettes.

A slide lid 3 is associated to the upper portion of the external container 2; also the lid has a substantially box-like shape and it is free to move in alternating manner in a direction that is transverse to the package 1. This lid presents a transverse extension that is equal to the one of the external container, but it has a lesser height h so that it only involves the upper portion of the external container 2. Indicatively the height h of the slide lid 3 is equal to approximately a fourth of the height H of the external container 2.

The external container 2, separately illustrated in figures 9- 12, includes: two main opposite lateral walls 20, 21, which define the external sides with the largest size of the package; two secondary walls 22, 23, also opposite each other, which instead define the external sides of smaller size; and finally a back wall 24 which closes off the package below. Also identified is an upper wall 28 which reproduces only partially the upper face of the rectangular parallelepiped.

In its upper portion the external container 2 exhibits two openings: an access opening 25 and a sliding window 27.

The access opening 25 defines a wide opening in the upper wall 28 that extends from the corner with the second secondary lateral wall 23 up to a median section of the package. The access opening 25 further involves the two main lateral walls 20, 21, along which two insertion holes 25a are defined, having a U-shape and a depth that is equal to or less than the height h of the slide lid 3.

The sliding window 27, arranged to allow the lateral insertion of the slide lid 3, defines an opening that involves the upper part of the first secondary lateral wall 22 and that extends from the corner with the upper wall 28 for a length that is equal to the height h of the slide lid. The sliding window 27 moreover involves the two main lateral walls 20, 21 , along which two grip openings 27a are defined, having a U-shape and running transversely to the package 1.

From the description of the access opening 25 and the sliding window 27 it becomes clear that the upper portion of the external container 2 defines an external bridge element 26 that connects from above the two main lateral wall 21 , 22 in the part not taken up by the access opening. The external bridge element 26 comprises two lateral tabs 20a, 21a that extend from the two main lateral walls 20, 21 of the external container 2 and an upper portion, corresponding to the upper wall 28 of the external container, that connects them.

The slide lid 3, separately visible in figures 14- 17, comprises an upper wall 38, two main lateral walls 30, 31 and a secondary lateral wall 32, to define the shape of a rectangular parallelepiped with two open faces: the internal face and one of the lateral faces of minor extension. The opening of this latter face in particular defines a lateral opening 33 that allows the lid 3 to slide above the internal wrapper 101. The two main lateral walls 30, 31 both comprise a lower lip 30a, 31a, which defines a portion of the lateral wall of a dimension greater than the height h of the slide lid 3. The lip 30a, 31a is located at a median section of the slide lid.

The lid is inserted into the previously described sliding window 27, and it is slidable between a closing position, in which it obstructs the access opening 25, and an open position in which the access opening 25 is at least partially free.

In the closing position, illustrated in figure 1, the slide lid 3 is brought to abut against the second secondary lateral wall 23 of the external container 2. In this position the single secondary lateral wall 32 of the lid 3 is aligned with the first secondary lateral wall 22 of the external container 2, so as to close the sliding window 27. At the same time the upper wall 38 of the lid 3 covers the access opening 25, defining a continuous upper face together with the upper wall 28 of the external container 2. The main lateral walls 30, 31 of the lid 3 cover the insertion holes 25a located on the corresponding main lateral walls 20, 21 of the external container 2.

In the open position, illustrated in figure 2, the slide lid 3 is moved laterally outward in comparison to the previously described position, until the previously described lips 30a, 31a come to abut against the internal surface of the first secondary lateral wall 22 of the external container 2. In this position the single lateral secondary wall 32 of the lid 3 distances itself from the first secondary lateral wall 22 of the external container 2. At the same time the upper wall 38 and the main lateral wall 30, 31 of the lid 3 are pulled away from the access opening 25 and its lateral insertion holes 25a, so that the cigarettes 100 contained by the package 1 are accessible.

It should be noted that the slide lid 3 moves internally with regard to the external container 2 without resting on any portion of the latter. It should furthermore be noted that the external bridge element 26 previously defined constitutes an upper constraint that prevents the slide lid 3 from becoming detached from the external container, as well as an actual guide for the linear movement of the slidable element.

The cigarette package 1 according to the present embodiment further comprises an internal frame 4, represented separately in the enclosed figures 19-22.

The internal frame 4 is enclosed inside the external container 2; in particular it comprises walls or portions of walls that internally abut against the respective walls of the external container 2. The equivalence of the dimensions of these walls defines a stable position for the internal frame 4 inside the external container 2, so that the internal frame 4, even though it is not attached by gluing, can be said to be integral with the external container 2.

The internal frame 4 in particular presents two main lateral walls 40, 41, a secondary lateral wall 43 and an upper wall 48 that internally abut against the corresponding walls of the external container 2. The secondary lateral wall 43 of the internal frame 4 in particular rests on the second of the secondary lateral walls 23 of the external container, in other words the wall without the sliding window 27.

The two main lateral walls 40, 41 of the internal frame 4 only partially reproduce the faces of the rectangular parallelepiped that constitutes the package 1. In particular, two sections of these faces remain open: the first, on the inside at the upper corner of the second secondary lateral wall 23 serves to free the insertion holes 25a of the access opening 25; the second, on the inside at the lower corner of the first secondary lateral wall 22 is not present for reasons of saving material. The secondary lateral wall 43 and the upper wall 48 also present discontinuous parts where the main lateral walls 40, 41 are open.

Particular attention should be paid to the portion of the internal frame 4 located at the external bridge element 26. This portion in fact reproduces the features of the abovementioned bridge element 26, defining a corresponding internal bridge element 46. The slide lid is inserted into the gap between the internal bridge element 46 and the external bridge element 26.

The internal bridge element 46 thus constitutes a lower constraint that impedes the movement of the slide lid 3 towards the inside of the package 1 as it is emptied of its contents; one should in fact note that in a full package the internal wrapper 101 supplies a further surface to guide the slide lid. Moreover the internal bridge element 46 collaborates with the external bridge element 26 in defining a sliding guide for the transverse movement of the slide lid 3.

With reference to figure 8, the number 2' indicates a first blank intended for the formation of the external container 2. The blank consists of a length of flat paper material that is foldable along predetermined weakened lines that define the panels and flaps intended to overlap in predetermined fixation areas for the assembly of the package 1.

The first blank 2' contains: two main lateral panels 20', 2 V for forming the main lateral walls 20, 21 ; two secondary lateral panels 22', 23' for forming the secondary lateral walls 22, 23; a back panel 24' for forming the back wall 24; an upper panel 28' for forming the upper wall 28; five attachment flaps 28a', 22a', 23a', 24a', 24b'. Naturally, the shapes and dimensions of the panels are the same as those of the respective walls they will form.

The two main lateral panels 20', 2 Γ extend from the two opposite sides of the bottom panel 40'. The first main lateral panel 20' presents on the opposite side the upper panel 28', whereas from the other two sides the respective secondary lateral panels 22', 23' extend. The second main lateral panel 2 Γ presents on the opposite side an upper flap 28a', whereas from the other two sides lateral flaps 22a', 23a' extend. From the ends of the two lateral flaps 22a', 23a' two bottom flaps 24a' and 24b' extend at positions that are alongside the bottom panel 24'.

In order to obtain the external container 2, after performing the necessary folding along the weakened lines, the following are attached, for example by means of glue: the upper flap 28a' below the upper panel 28'; the first lateral flap 22a' inside the first secondary lateral panel 22'; the second lateral flap 23a' inside the first secondary lateral panel 23'; the two bottom flaps 24a' and 24b' above the bottom panel 24'.

With reference to figure 13 the number 3' indicates a second blank for the formation of the slide lid 3. The blank consists of a length of flat paper material that is foldable along predetermined weakened lines that define the panels and flaps intended to overlap in predetermined fixation areas for the assembly of the package 1. The second blank 3' comprises: two main lateral panels 30', 3 Γ for forming the main lateral walls 30, 31; a secondary lateral panel 32' for forming the secondary lateral wall 32; an upper panel 38' for forming the upper wall 38; a lateral attachment flap 32a'. Naturally, the shapes and dimensions of the panels are the same as those of the respective walls they will form.

The two main lateral panels 30', 31' extend from the two opposite sides of the upper panel 38'. The first main lateral panel 30' presents on one of its sides the second lateral panel 32'; whereas the second main lateral panel 3Γ presents the lateral flap 32a' on the corresponding side.

In order to obtain the slide lid 3, after performing the necessary folding along the weakened lines, the lateral flap 32a' is attached, for example by means of glue, to the inside of the secondary lateral panel 32'.

With reference to 18 the number 4' indicates a third blank for the formation of the internal frame 4. The blank consists of a length of flat paper material that is foldable along predetermined weakened lines that define the panels and flaps intended to overlap in predetermined fixation areas for the assembly of the package 1.

The third blank 4' comprises: two main lateral panels 40', 41' for forming the main lateral walls 40, 41 ; a secondary lateral panel 43' for forming the secondary lateral wall 43; an upper panel 48' for forming the upper wall 48; an upper attachment flap 48a'. Naturally, the shapes and dimensions of the panels are the same as those of the respective walls they will form.

The two main lateral panels 40', 41' extend from the two opposite sides of the secondary lateral panel 43'. The first lateral panel 40' presents at its upper side the upper panel 48'; whereas the second main lateral panel 41' presents the upper flap 48a' at its upper side.

In order to obtain the internal frame 4, after performing the necessary folding along the weakened lines, the upper flap 48a' is attached, for example by means of glue, below the upper panel 48'.

In order to obtain the package 1, the operations of folding and attaching the blanks is done in inverse order from the one described above. First the internal frame 4 is formed and then the slide lid 3, which is placed over the first, and then the external container 2 is closed over these first two elements. Thus the slide lid 3 is slidably constrained inside the gap between the internal frame 4 and the external container 2.

From the description of the method for forming the package 1 one can again infer that the slide lid 3 is sandwiched between the internal frame 4 and the external container 2.

Figures 23-25 represent a second embodiment of the cigarette package according to the present invention.

It should be noted that the constitutive elements and their parts are identified by the same reference number as used in the description of the first embodiment.

The two embodiments are substantially identical; the only exception is a morphological detail of the external container 2 and the internal frame 4.

In the first embodiment the second secondary wall 23 extends for the entire height H of the external container, whereas the corresponding wall 43 of the internal frame 4 is interrupted by the slide Lid 3.

Contrary to this in the second embodiment it is the secondary external wall 23 that is interrupted by the lid 3, in other words the upper opening defined by the external container 2 is no longer U- shaped, but in the shape of an L, excluding one of the upper edges of the package 1. A protruding portion 43a of the internal wall 43 instead projects outside of the external container 2 for the entire height H, thereby replacing the missing portion of the external container 2. The main lateral walls 40, 41 of the internal frame 4 further provide respective protruding portions 40a, 41a that define a slightly protruding rim with respect to the lateral lower profile of the upper L-shaped opening of the external container 2, in addition joining the projecting portion 43a of the secondary wall 43 above. In this embodiment it is the main lateral walls 40, 41 of the internal frame 4, in particular their protruding portions 40a, 41a, that define the U-shaped insertion holes 25a that surround the access opening 25.

It should be noted that, while in the first embodiment the internal frame 4 is completely contained by external container 2, in the second embodiment instead it presents projecting portions 40a, 41a, 43a that are visible from the outside at the upper edge of the package 1 adjacent to the access opening 25. It should further be noted that, while in the first embodiment the slide lid 3 in the closed position is brought to abut against the upper portion of the secondary wall 23 of the external container 2, this does not occur in the second embodiment. In this second embodiment the slide lid 3 moves externally with respect to the protruding portion 43a that laterally closes the access opening 25. In the closed position, the lateral opening 33 of the slide lid is therefore located on the same plane as the abovementioned protruding portion 43a, without any interference or abutment of the lid 3 with the latter.

Of course, a person skilled in the art can apply numerous modifications and variants to the findings described above in order to satisfy contingent and specific requirements, all of which fall within the scope of protection of the invention as defined by the following claims.
