Description

FILLING INSERT FOR A PACKET OF SMOKING ARTICLES, COMBINATION WITH A DRAWER, APPARATUS, MACHINE, BLANK, PACKET AND METHODS

ASSOCIATED

FIELD OF THE INVENTION

Embodiments described here concern a filling insert for a packet of smoking articles and the corresponding blank.

In particular, embodiments described here concern a filling insert which can be used inside an assembly or bundle formed by organized groups of smoking articles wrapped in a wrapping sheet such as for example cigarettes, cigars, cigarillos, or suchlike, for making packets of smoking articles.

Embodiments described here also concern an apparatus and a method for forming the filling insert in question.

BACKGROUND OF THE INVENTION

It is known that, as a result of regulations or legislation in the field of smoking articles, the free surface available in the design or sizing of the packets can, or will be able in the future to, be greatly reduced depending on the country. In particular, it is conceivable that in the future packets of smoking articles will have only certain predefined sizes, so that adapting the size of the packet to the actual size and the number of smoking articles contained therein could become difficult if not impossible.

For example, in the case of smoking articles with a reduced diameter, such as so-called "slim" cigarettes, or if it is desired to contain fewer smoking articles while maintaining the pre-determined size of the packet, it can become necessary to adapt the internal volume of the packets to prevent the smoking articles, either because of their smaller diameter, or because they are fewer in number, from moving freely inside the bundle in an unwanted manner, with the risk of being damaged.

To this purpose, one approach can be to provide, in the assembly or bundle formed by organized groups of smoking articles already wrapped in a wrapping sheet, filling elements or inserts that compensate and fill the empty spaces caused by different sizes or quantities of smoking articles compared to the predetermined volume of the packet. In essence, the filling elements or inserts will define one or more dedicated compartments in the bundle, with a volume coherent with the volume occupied by the smoking articles which will actually be provided in the bundle itself, thus preventing the smoking articles from being free to move in an unwanted manner.

If the group of smoking articles could move inside the packet, or inside a forming drawer of organized groups of smoking articles, during the steps of packaging the packet, or during subsequent storage and distribution steps, the smoking articles could be subjected to mechanical stresses that could cause damage to them. In particular, the relative movements of the smoking articles could cause knocks especially in the ends opposite the filters, risking making the tobacco escape or in any case damaging the shape of the smoking article.

In the field of packing machines, apparatuses are known for the formation of organized groups of smoking articles comprising feed devices configured to insert, by means of a thrust assembly, one or more organized groups of smoking articles in forming drawers, or pockets, provided in suitable housing devices.

In this context, there are various solutions to insert, inside the forming drawer, said filling elements or inserts before the transfer of the organized group of smoking articles inside the forming drawer itself.

Known solutions have the disadvantage that forming the group of smoking articles together with the insert can be complex, since both the smoking articles and the inserts must be maintained in the correct reciprocal positions until both are wrapped by the wrapping sheet.

Document DE-A- 102015014182 describes an insert for a cigarette packet, able to divide, inside the latter, the cigarettes into two groups. The insert has a central body with a parallelepiped shape and a triangular base consisting of an upper base and two sides that converge, but do not touch. From the convergence zone of the two sides, L-shaped elements depart laterally, each formed by two consecutive right-angled walls. This document also describes a method to combine the insert in the forming drawer of the groups of cigarettes.

Document WO-A-2016/083442 describes a first variant of a hollow parallelepiped shaped spacer, with a triangular base and a lid provided with lateral flaps. A second variant described provides that the spacer consists of a triangular hollow body formed by only two walls and the lid, while the walls project laterally and symmetrically, defining protruding fins that are able to lie adjacent to the walls of the packet.

Document DE-A-1020141 16784 describes a method and apparatus to produce cigarette packets, in which there is a housing drawer with separate chambers, into which an insert and smoking articles are respectively introduced. The insert is provided, on the lateral walls, with stiffening fins protruding toward the inside of the insert. The housing drawer comprises, in particular, recesses provided with at least one passage aperture through which to insert at least the smoking articles. This prior art document also describes walls, present in the housing drawer, able to separate the insert from the smoking articles inserted in the recesses.

Document EP-A-2.982.607 describes an insert and a drawer with stabilizing guides for the insert, protruding toward the inside of the drawer.

Document EP-A-3.025.979 describes a packet with a double internal spacer.

There is therefore a need to perfect a filling insert for a packet of smoking articles and corresponding blank, apparatus and method for forming said insert, which can overcome at least one of the disadvantages of the state of the art.

In particular, one purpose of the present invention is to obtain a filling insert for smoking articles which can maintain its position with respect to the smoking articles both during the formation of the packet and also during the use of said packet.

Another purpose of the present invention is to provide a filling insert that is simple and economical to make.

The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.

Other limitations and disadvantages of conventional solutions and technologies will be clear to a person of skill after reading the remaining part of the present description with reference to the drawings and the description of the embodiments that follow, although it is clear that the description of the state of the art connected to the present description must not be considered an admission that what is described here is already known from the state of the prior art.

DETAILED DESCRIPTION OF SOME EMBODIMENTS

We shall now refer in detail to the various embodiments of the present invention, of which one or more examples are shown in the attached drawings. Each example is supplied by way of illustration of the invention and shall not be understood as a limitation thereof. For example, the characteristics shown or described insomuch as they are part of one embodiment can be adopted on, or in association with, other embodiments to produce another embodiment. It is understood that the present invention shall include all such modifications and variants.

Before describing these embodiments, we must also clarify that the present description is not limited in its application to details of the construction and disposition of the components as described in the following description using the attached drawings. The present description can provide other embodiments and can be obtained or executed in various other ways. We must also clarify that the phraseology and terminology used here is for the purposes of description only, and cannot be considered as limitative.

Forms of embodiment described here using figs. 1-4 concern a filling insert 10 for a packet 20 of smoking articles 13 organized into one or more groups 12. In particular, the packet 20 can be the type that comprises internally an internal assembly or bundle, comprising one or more organized groups 12 of smoking articles 13 and at least one filling insert 10 wrapped in a wrapping sheet 28.

Fig. 1 is used to describe an example of a rigid packet 20 with a hinged lid that comprises a cup-shaped rigid external containing casing 22 and an upper lid 24 hinged to the external containing casing 22 by a hinge 26 (see fig. 1 ). The external containing casing 22 can contain inside it an internal assembly 1 1 or bundle, comprising one or more organized groups 12 of smoking articles 13 and at least one filling insert 10 wrapped by a wrapping sheet 28, for example aluminum, metallized paper, foil, which in turn can be partly enclosed by a collar 30 which can slide toward the outside to be partly extractable from the external containing casing 22.

When the lid 24 is closed, the packet 20 has a rectangular parallelepiped shape, delimited laterally by two larger lateral walls, front 32 and rear 34, parallel to each other and opposite, and by two smaller lateral walls 36, also parallel and opposite.

According to some embodiments, the filling insert 10 comprises a filling body 14 and stabilization members 16 defined by appendixes protruding toward the outside from the lateral surface of the filling body 14.

In possible embodiments, the stabilization members 16 extend in opposite symmetrical directions in continuity with a first face, or lateral base wall 40 of the filling body 14. Advantageously, in this way, it is possible to define a strong filling insert 10, with stabilization members 16 and lateral base face 40 which can therefore lie essentially on an entire side of the cigarette packet.

In possible solutions, advantageously the filling body 14 can be essentially similar to a prism with a polygonal base or cross section, for example with three sides, four sides, five sides, six sides, seven sides, eight sides or even more than eight sides. The first base lateral face 40 is, therefore, a base lateral face that defines one side of said prism with the polygonal base.

In particular, the filling insert 10 is able to be inserted into a containing compartment 129 of a drawer 128 for the formation of organized groups 12 of smoking articles 13.

In some embodiments, the filling insert 10 can have the shape and sizes suitable to be inserted into the containing compartment 129. In particular, the transverse length of the stabilization members 16 can be correlated to the transverse size of the containing compartment 129 to prevent transverse movements of the filling insert 10 inside the containing compartment 129.

According to some embodiments, the transverse length of the stabilization members 16 protruding from the filling body 14 is correlated to the transverse size of the containing compartment 129, so that the stabilization members 16 cooperate with the containing compartment 129 to stabilize the filling insert 10 therein.

According to some embodiments, described for example with reference to figs. 2 and 14-16, the filling body 14 has a prismatic shape, having a lateral surface defined by at least two lateral faces.

According to possible variant embodiments described for example with reference to fig. 17, the filling body 14 can have a round or oval section.

According to further possible variants, the filling body 14 can have a trapezoidal section, or a rhomboidal, pentagonal, hexagonal, or other polygonal section.

According to some embodiments, the filling body 14 can have a regular or irregular polygon section.

According to some embodiments, the filling insert 10 can have a plurality of consecutive lateral faces two by two, suitable to be positioned at least partly in interference with the lateral walls of the containing compartment 129 and/or the walls 32, 34, 36 of a packet 20.

According to some embodiments, the lateral faces of the filling body 14 can be flat, or can be concave, or convex.

According to other embodiments, the edges defined by consecutive lateral faces can be sharp edged or rounded.

According to preferred embodiments, described for example with reference to fig. 3, the filling body 14 can have a prismatic shape with a triangular section, defined by three lateral faces 40, 42, 44, one of which is the first lateral face 40 serving as a base, a second face, or lateral wall 42 and a third face, or lateral wall 44, which function as sides.

According to possible solutions, the second lateral face 42 and the third lateral face 44 are joined to each other along a vertex edge 46 and to the first lateral face 40 along respective lateral edges 43, 45. According to some embodiments, the stabilization members 16 protrude from an edge 43, 45, 46 defined by two adjacent lateral faces 40, 42, 44 of the lateral surface of the filling body 14.

According to some embodiments, the stabilization members 16 comprise at least one fin 50, or a claw.

According to possible solutions, described with reference to fig. 3, a pair of fins 50 are provided extending in a symmetrical position from each lateral edge 43, 45 defined by the first base lateral face 40 and by a respective one of either the second lateral face 42 or the third lateral face 44.

According to possible solutions, the fins 50 extend in continuity with the first base lateral face 40.

According to possible solutions, two or more pairs of fins 50 can be provided, distanced along the longitudinal extension of the filling insert 10 to clamp its transverse position along the entire longitudinal development in the containing compartment 129 and/or in the packet 20.

The one or more pairs of fins 50 can be associated with a single lateral face 40, 42, 44 of the filling insert 10 or fins 50 can be provided associated with each edge 43, 45, 46 between two adjacent lateral faces 40 , 42, 44.

According to some embodiments, the fins 50 and the vertex line 46 cooperate with the containing compartment 129 of a drawer 128 and/or with the external containing casing 22 of a packet 20 so as to clamp the position of the filling insert 10, preventing any possible transverse displacements thereof.

According to possible solutions, the overall width given by the base lateral face 40 and by a pair of opposite fins 50 can be substantially equal to the width of the rear larger lateral wall 34 of a packet 20. In this way, in a finished packet 20, the lateral face 40, wrapped in the wrapping sheet 28, can be positioned adjacent to the larger rear lateral wall 34 with the fins 50 each facing toward a smaller lateral wall 36.

According to other embodiments, it can be provided that the filling insert 10 has a length of the base lateral face 40 bigger than that of the vertex edge 46, providing a rounded connection between them by means of a perimeter line that is rounded to define a neck 52 of rounded shape, segmented, or with mixed linear and segmented sections. The different lengths and the rounded neck 52 allow, when the filling insert 10 is positioned inside a packet 20, to more easily reach the smoking articles 13 positioned around it inside the wrapping sheet 28.

According to possible solutions, the filling body 14 can be made as a solid body, for example in a plastic or polymeric material.

According to preferred embodiments, described with reference to figs. 2 and 3, the filling body 14 can have a box-like structure, that is, it can be empty inside.

According to a possible solution, the filling insert 10 can be made starting from a blank 100, or from a sheet material such as paperboard, cardboard, paper or suchlike, suitably shaped and worked, shown by way of example in fig. 4. The blank 100 of the type used in the embodiments described here can be typically a flat sheet of cardboard, paperboard or paper, provided with pre- weakened folding lines or pre-creasing lines, which define panels and flaps to be folded to make the lateral faces of the filling insert 10. Hereafter, we will indicate, where possible, the flaps and panels of the blank 100 with a similar reference number, followed by an inverted comma ('), to that of the respective lateral faces of the filling insert 10 formed by said panels and flaps.

According to some embodiments, the blank 100 comprises a plurality of longitudinal panels 140', 141 ', 142', 144', connected to each other by longitudinal folding lines 143', 145' and by one or more intermediate folding lines 146'.

In particular, the blank comprises two external longitudinal folding lines 143', 145' that define respective external longitudinal panels 140', 14Γ and at least one main central panel 149'.

According to some embodiments, the main central panel 149' comprises at least one intermediate longitudinal folding line 146' that defines intermediate longitudinal panels 142', 144'.

According to some embodiments, the number of longitudinal panels 140', 141 ', 142', 144' is equal to the number of lateral faces 40, 42, 44 of the filling body 14 to be made, plus one. In this way, it is possible to define the prismatic shape of the filling body 14, stabilizing its shape by overlapping the external longitudinal panels 140', 141 ' located at the opposite ends of the blank 100 that define the first base lateral face 40.

According to these embodiments, the first base lateral face 40 can be partly formed by the external longitudinal panel 140', and partly by the external longitudinal panel 141 ' superimposed on the external longitudinal panel 140'.

The intermediate longitudinal panels 142', 144', folded one with respect to the other with respect to the intermediate longitudinal folding line 146', respectively form the second and third lateral faces 42, 44, while the intermediate longitudinal folding line 146' forms the vertex segment 46.

The bigger external longitudinal panel 140' and the smaller external longitudinal panel 141 ', folded with respect to the respective adjacent intermediate longitudinal panels 142', 144' along the external longitudinal folding lines 143', 145' and superimposed one above the other, form the base lateral face 40.

The bigger external longitudinal panel 140' is advantageously folded toward the inside of the filling body 14 so as to abut against the external longitudinal folding line 145' inside the edge 45. In this way, it is possible to confer on the filling insert 10 a generally stable shape, without needing to provide the use of glues or adhesives between the overlapping external longitudinal panels 140', 141 '.

The fact that the blank 100 has an asymmetrical shape with respect to the intermediate longitudinal folding line 146' is advantageous since it allows to obtain a filling insert 10 able to maintain its shape, at least in correspondence with the first base lateral face 40.

According to some embodiments, the external longitudinal folding lines 143', 145' and/or the intermediate longitudinal folding line 146' are partial folding lines, being provided with pre-creasing segments separated by cutting lines 147' that define cut out portions 150'. Advantageously, the cutting lines 147' are obtained or made on the main central panel 149'.

The cutting lines 147' have an at least in segments partly curved development that deviates from the straight line passing through the pre-creasing segments that define the external longitudinal folding lines 143', 145'.

The cut out portions 150' defined by the cutting lines 147' of the first external longitudinal folding line 143' and the second external longitudinal folding line 145' advantageously face each other. In this way, when the bigger external longitudinal panel 140' and the smaller external longitudinal panel 141 ' are folded with respect to the intermediate longitudinal panels 142', 144' and superimposed, the cut out portions 150', extending continuously from the first base lateral face 40, form the fins 50.

Thanks to the fact that the cutting lines 147' are formed or made on the main central panel 149', it is possible to obtain the stabilization members 16, in particular the fins 50, that extend in opposite symmetrical directions in continuity with the first base lateral face 40 of the filling body 14.

According to further embodiments, the blank 100 can also provide that the intermediate longitudinal panels 142', 144' are symmetrically shaped with respect to the intermediate longitudinal folding line 146', providing a transverse cutting line 152' which defines, in use, the neck, or recess 52 of the filling insert 10.

Embodiments described here concern a forming apparatus 60 for the filling insert 10, comprising an incision and cutting unit 62 configured to incise and shape a blank 100 starting from a flat sheet of paperboard, paper or cardboard 64, for example wound in a coil, and a shaping unit 66 configured to shape the blank 100 and fold it as appropriate to form a filling insert 10 ready to be used.

According to some embodiments, the forming apparatus 60 also comprises a drawing device or a drawing roller 68, possibly cooperating with a conveyor plane or belt, and configured to feed the flat sheet of paperboard 64 in a direction of feed D to the incision and cutting unit 62.

According to some embodiments, the incision and cutting unit 62 comprises an incision device 70 configured to incise the flat sheet of paperboard 64 to make the external longitudinal folding lines 143', 145' and the intermediate longitudinal folding line 146' and/or cut it to make the cutting lines 147'.

In some embodiments, the incision device 70 can comprise a cylindrical roller, on whose external surface cutting elements are provided, suitable to incise and/or cut a sheet of paperboard 64 by exerting a pressure on it during the rotation of the roller around its central axis.

Downstream of the incision device 70, in the direction of feed D, the incision and cutting unit 62 comprises a cutting device 72, suitable to cut the flat sheet of paperboard 64 in a transverse direction to the direction of feed D, both to cut the blank 100 to size, and also to cut it along the transverse cutting line 152'. According to some embodiments, at exit from the incision and cutting unit 62 a blank 100 is obtained which, in a view from above, is disposed on a substantially horizontal plane in the same position as the blank 100 in fig. 4.

According to some embodiments, the blank 100 exiting from the incision and cutting unit 62 is received by a removal device 76 configured to remove the blank 100 and transfer it in correspondence with the shaping unit 66.

According to embodiments described using figs. 5 and 6, the shaping unit 66 can be disposed above and offset laterally with respect to the incision and cutting unit 62. According to this embodiment, the removal device 76 can comprise holding members 78, suitable to hold a blank 100, lifting it from a support plane, and movement members, not shown. The movement members can be configured to move the holding members 78 and the blank 100 held by them from the substantially horizontal position to a substantially vertical position, rotating it by about 90° in the direction of rotation R.

In this way, the introduction unit 126 can, on each occasion, translate the organized groups 12 of smoking articles 13 fed by the feed unit 122 and introduce them into the respective drawers 128 of the transfer unit 124.

According to some embodiments, the introduction unit 126 comprises a plurality of thruster elements 130, equal in number to the number of drawers 128 to be filled on each occasion.

According to some embodiments, the introduction unit 126 comprises one or more actuation members, not shown in the drawings, configured to drive in the desired manner the translation of the thruster elements 130 between a condition of non-interference with the organized groups 12 of smoking articles 13 and a condition of transfer into the respective drawers 128 of the transfer unit 124. According to some embodiments, the transfer unit 124 can rotate around a central axis X along a transfer path P to take the drawers 128 from at least one entrance station 132 for the smoking articles, into which the organized groups 12 of smoking articles 13 are introduced, to an exit station 134, in which the organized groups 12 are picked up and sent to subsequent packaging steps.

According to some embodiments of the present invention, upstream of the entrance station 132 of the smoking articles, along the transfer path P, an entrance station 136 for the inserts is disposed, in which the filling inserts 10 are introduced. According to these embodiments, the filling insert 10 is inserted into a drawer

128 before the introduction of the organized groups 12 of smoking articles 13. According to possible solutions, it can be provided that the thruster elements

130 are configured so as to introduce the organized groups 12 of smoking articles 13 into the space outside the volume defined and/or occupied by the filling body 14.

According to possible variant solutions, for example where the filling body 14 has a box-like shape, the thruster elements 130 can be configured to introduce the organized groups 12 of smoking articles 13 into the space outside the volume defined by the filling body 14, or in the internal space.

According to some embodiments, described with reference to figs. 12 and 13, in correspondence with the insert entrance station 136, the forming apparatus 60 of the insert can be disposed, positioned so that the shaping unit 66 is disposed aligned with a drawer 128.

In particular, according to these embodiments, in the insert entrance station 136, the shaping drawer 90 and the housing compartment 129 of a drawer 128 are perfectly aligned with each other in the axial direction L of the filling insert 10.

According to these embodiments, the filling insert 10 can be formed in line starting from the flat sheet of paperboard 64, it can be cut and shaped by the insert forming apparatus 60 and inserted directly into the housing compartment

129 of a drawer 128, translating it in the axial direction L by the thruster device 104.

According to this embodiment, it can be provided that the folding device 96 is associated with the transfer unit 124 so that the movements of the latter are correlated to each other.

For example, it can be provided that the connection pin 106 between the two arms 102 of the folding device 96 is centered on the central axis X of the transfer unit 124.

In particular, according to some embodiments, the insert forming apparatus 60 can be disposed in an alignment direction T, on the opposite side of the transfer unit 124 with respect to the feed hopper 122 and the introduction unit 126.

In this way, the filling insert 10 and the organized groups 12 of smoking articles 13 are inserted into a respective drawer 128 in parallel directions but in opposite senses.

Thanks to the presence of the stabilization members 16, the filling insert 10 according to the present invention, once inserted in a drawer 128, remains stably positioned inside the housing compartment 129 thanks to the stabilization members 16 which abut against opposite lateral walls of the housing compartment 129 and prevent any displacement of the filling insert 10 in the transverse direction.

The use of a filling insert 10 suitable for self-positioning and self-stabilization in a drawer 128 advantageously allows to reduce the complexity of the packaging machine 120 and to speed up the process of forming and packing the organized groups 12 of smoking articles 13, since it is not necessary to provide further additional stabilizing elements.

According to some embodiments, downstream of the exit station 134 a wrapping device can be provided, not shown in the drawings, configured to wrap the organized groups 12 of smoking articles 13, associated with the respective filling insert 10, in a wrapping sheet 28, before sending them to the next steps of packaging a packet 20.
