Abstract
Description
[0001] “SUPPORT TRAY AND CORRESPONDING PRODUCTION METHOD”
[0002] FIELD OF THE INVENTION
[0003] The present invention concerns a support tray for elongated elements, for example tubular or stick or bar shaped, in particular, but not limited to, of the flexible or deformable type, for example smoking articles such as cigarettes, cigars, cigarillos or suchlike. The present invention also concerns a process for making the support tray.
[0004] BACKGROUND OF THE INVENTION Packages, or packets, for containing elongated elements, for example tubular or stick or bar shaped, for example smoking articles, such as cigarettes, cigars, cigarillos, or suchlike are known.
[0005] In the case of smoking articles, these are normally grouped in such a way as to define, as a whole, a parallelepiped, around which an internal containing casing, or internal wrapper, is then wrapped, which is then inserted into an external containing body, thus forming the packet.
[0006] However, a disadvantage of such known packets is that they are not suitable for containing elongated elements of the type in question and having a variable crosssection, for example having a frustoconical shape, because, since these are arranged against each other, each smoking article could be crushed and / or ruined, thus compromising its integrity.
[0007] In this regard, solutions are known that provide a box-shaped package in which there is a support tray having a wall parallel to the bottom of the containing body and provided with a plurality of positioning holes for the elongated elements, keeping them positioned individually and, therefore, separated from each other.
[0008] An example of these solutions is described in document GB 2040884, which describes stackable trays each having a plurality of holes, each configured to receive objects such as yoghurt pots or plant pots, for example.
[0009] Other solutions known in the art describe box-shaped packages in which the support tray is conformed so as to have two walls parallel to each other and to the bottom of the containing body, and both provided with a plurality of positioning holes. Each positioning hole of the upper wall is axially aligned with a respective positioning hole of the lower wall, so that a same oblong element, for example a vial, a flask or a bottle, passes through both of them. Some examples of these types of packages are described in documents US 5057282, US 3682597, EP 1989119 and JP Hl 135081.
[0010] However, known solutions have the disadvantage that they are rather complex and that special, bulky and expensive equipment is required to make them.
[0011] Furthermore, the processes for making such support trays or the respective packages, as well as for preparing such trays to receive and support the elongated elements, can also be rather elaborate and complex.
[0012] There is therefore the need to perfect a support tray that can overcome at least one of the disadvantages of the state of the art.
[0013] In particular, one purpose of the present invention is to provide a support tray that is easy to produce and has low production costs.
[0014] Another purpose of the present invention is to provide a support tray by means of a production process that is simple and highly efficient. 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.

[0036] To facilitate comprehension, the same reference numbers have been used, where possible, to identify identical common elements in the drawings. It is understood that elements and characteristics of one embodiment can be conveniently combined or incorporated into other embodiments without further clarifications. DESCRIPTION OF SOME EMBODIMENTS OF THE PRESENT INVENTION
[0037] With reference to fig. 1, a support tray 10 according to the present invention is suitable to support elongated elements 200 in a substantially upright position.
[0038] According to possible embodiments, the support tray 10 is insertable into a containing body 101 to thereby form a box-shaped package containing the plurality of elongated elements 200.
[0039] The oblong or elongated elements 200 can, for example, be tubular or stick or bar shaped, in particular but not exclusively of a flexible or deformable type, and comprise a lower end 201 and an upper end 202 (fig. 3).
[0040] According to preferred embodiments, shown in fig. 3, the elongated elements 200 are smoking articles with a frustoconical shape, wherein the lower end 201 is defined by the mouth end, which is able to be brought at the mouth of the consumer and can be provided with a filter, and the upper end 202 is defined by the lighting end, which can be lit to smoke the smoking article. As shown, the lower end 201 has a smaller cross-section than the upper end 202.
[0041] The support tray 10 is made starting from a single flexible blank 110 (fig. 4), as will be described in detail below.
[0042] Preferably, the blank 110 is made of a sheet material, for example cardboard, paperboard, paper or similar materials, and has a thickness such that it can be easily folded, while guaranteeing that a sufficiently rigid and resistant structure is created, capable of supporting the elongated elements 200.
[0043] In particular, the blank 110 is shaped and folded in such a way that the support tray 10 (fig. 1) essentially comprises an upper transverse wall 11, a lower transverse wall 12 parallel and opposite the latter, and at least a first side wall 13 and a second side wall 15 opposite each other and perpendicular to the upper and lower transverse wall 11, 12.
[0044] The support tray 10 has a parallelepiped shape, wherein the upper and lower transverse wall 11, 12 and the first and second side wall 13, 15 can have a rectangular or square shape.
[0045] The first and second side wall 13, 15 have respective lower end parts which extend beyond the lower transverse wall 12, on the opposite side with respect to the upper transverse wall 11, and define two corresponding support legs 19, 20. In particular, each support leg 19, 20 consists of a superimposition and a stable joining with glue of respective portions of at least two panels 113a, 113b, 115a, 115b of the blank 110 (fig. 3a), as will be described in detail below. According to preferred embodiments, the support tray 10 also comprises a third side wall 16 and a fourth side wall 17, opposite each other and perpendicular to the first and second side wall 13, 15, thus defining a side skirt 14 around the upper and lower transverse wall 11, 12.
[0046] We must clarify that the third and fourth side wall 16, 17 can also have a rectangular or square shape, preferably coordinated with the shape of the first and second side wall 13, 15, so that the support tray 10 has the aforementioned parallelepiped shape. We must clarify that that the side walls 13, 15, 16, 17 have the function of giving a certain rigidity to the structure of the support tray 10.
[0047] Therefore, the support tray 10 advantageously comprises two further support legs 21, 22, defined by corresponding lower end parts of the third and fourth side wall 16, 17 which extend beyond the lower transverse wall 12, on the opposite side with respect to the upper transverse wall 11. In particular, each further support leg 21, 22 consists of a superimposition and a stable joining with glue of respective portions of at least two panels 116a, 116b, 117a, 117b of the blank 110 (fig. 3b), as will be described in detail below.
[0048] We must clarify that at least the respective lower end portions of the first, second, third and fourth side wall 13, 15, 16, 17 have a higher stiffness than the upper and lower transverse wall 11, 12.
[0049] In this way, the support tray 10 has the advantage of being more stable and of having a structure able to withstand any accidental deformations.
[0050] The upper transverse wall 11 is provided with a plurality of first holes 25 defining respective housing seats for the elongated elements 200 (figs, from 1 to 3).
[0051] The first holes 25 are arranged according to a certain positioning matrix, for example they are aligned and equally spaced apart from each other so as to homogeneously occupy the entire surface of the upper transverse wall 11. Furthermore, the first holes 25 preferably have a circular shape and a first diameter DI (figs. 2 and 4) having a size such as to accommodate each elongated element 200 with minimum play.
[0052] We must clarify that, in the case of frustoconical shaped smoking articles, the first diameter DI can have a size that is intermediate between the diameter of the lower end 201 and that of the upper end 202. The lower wall 12 is provided with a plurality of second holes 26 (fig. 2) axially aligned with the first holes 25 and configured so that the elongated elements 200 also pass through them.
[0053] Each of the second holes 26 is encircled by deformable flaps 28 configured to be bent by the elongated elements 200. In a first embodiment, shown in figs. 1-12, the deformable flaps 28 are contiguous, defined by through radial incisions 27 and hingedly arranged perimetrically around the second holes 26.
[0054] The deformable flaps 28 have the function of elastically deforming to delimit the second holes 26, which define a further housing seat for a corresponding elongated element 200, that is, a central opening having a size such as to allow the easy passage thereof, at the same time stably holding it by interference and stably keeping it in an upright position.
[0055] According to preferred embodiments, the second holes 26 have a circular shape.
[0056] Specifically, the second holes 26 have a second diameter D2 that is smaller than the first diameter DI of the first holes 25. For example, the second diameter D2 can have a size such that, in the absence of deformation of the deformable flaps 28, the regular passage of the lower end 201 of the elongated element 200 would be impeded.
[0057] According to possible embodiments, the radial incisions 27 can have an extension such as to define a closed annular profile, from which the deformable flaps 28 depart, having an external diameter DE even greater than the first diameter DI of the first holes 25. We must clarity that the external diameter DE is represented ideally in figs. 2 and 4 with a dashed line.
[0058] The blank 110 (fig. 4), although advantageously in a single body, is suitably shaped and comprises at least: a first main panel 111 which is configured to define, when the blank 110 is folded, the upper transverse wall 11; a second main panel 112 aligned with the first main panel 111 along an axis of symmetry X and configured to define, when the blank 110 is folded, the lower transverse wall 12; a first larger central panel 113a and a second larger central panel 115a which are connected, on opposite sides, to the first main panel 111 along the axis of symmetry X, and a first smaller central panel 113b and a second smaller central panel 115b which are connected, on opposite sides, to the second main panel 112 along the axis of symmetry X.
[0059] We must clarify that the first main panel 111 comprises the plurality of first holes 25 and that the second main panel 112 comprises the plurality of second holes 26.
[0060] According to some embodiments, the first and second larger central panel 113a and 115a, when the blank 110 is folded, are configured to define the first and second side wall 13, 15.
[0061] Furthermore, the first larger and smaller central panel 113a, 113b are connected to each other and, when the blank 110 is folded, the first smaller central panel 113b is configured to be superimposed and stably joined with glue to an end portion of the first larger central panel 113a, thus defining a first support leg 19.
[0062] The second larger and smaller central panel 115a and 115b are arranged on opposite sides with respect to each other and, when the blank 110 is folded, the second smaller central panel 115b is configured to be superimposed and stably joined with glue to an end portion of the second larger central panel 115a, thus defining a second support leg 20.
[0063] According to other embodiments, not shown in the drawings, the first and second side wall 13, 15 are respectively defined by the partial superimposition and stable joining with glue of the first and second smaller central panel 113b, 115b with the first and second larger central panel 113a, 115a. We must specify that, on the first smaller central panel 113b there is a layer of gluing, or adhesive, material Ml which is able to contact the corresponding end portion of the first larger central panel 113a and, when activated, allows to keep the first smaller central panel 113b glued and stably joined to it.
[0064] Moreover, there is also a layer of gluing, or adhesive, material Ml on the second smaller central panel 115b, which is able to contact the corresponding end portion of the second larger central panel 115a and, when activated, allows to keep the second smaller central panel 115b glued and stably joined to it.
[0065] By way of a non-limiting example, the gluing, or adhesive, material Ml can be a heat-sealable material, for example a heat-activated glue.
[0066] In accordance with preferred embodiments, a first and a second larger side panel 116a, 117a are connected to the first main panel 111 on opposite sides with respect to the axis of symmetry X, and a first and a second smaller side panel 116b, 117b are connected to the second main panel 112 on opposite sides with respect to the axis of symmetry X.
[0067] According to some embodiments, the first and second larger side panel 116a and 117a, when the blank 110 is folded, are configured to define the third and fourth side wall 16, 17. The first smaller side panel 116b, when the blank 110 is folded, is configured to be superimposed and stably joined with glue to an end portion of the first larger side panel 116a, thus defining a third support leg 21.
[0068] The second smaller side panel 117b, when the blank 110 is folded, is configured to be superimposed and stably joined with glue to an end portion of the second larger side panel 117a, thus defining a fourth support leg 22.
[0069] According to other embodiments, not shown in the drawings, the third and fourth side wall 16, 17 are respectively defined by the partial superimposition and stable joining with glue of the first and second smaller side panel 116b, 117b with the first and second larger side panel 116a, 117a. In general, the blank 110 is configured to be suitably folded and shaped, or divaricated, or indented, passing from a flattened configuration to an upright configuration. Specifically, the first and second main panel 111, 112, which in such flattened configuration are partially superimposed and in contact with each other, are able to be reciprocally separated and spaced apart to bring each other in parallel, thus forming the upper and lower transverse wall 11, 12, which are also perpendicular at least to the first and second side wall 13, 15, already defined by the superimposition and stable joining with glue of the first and second smaller central panel 113b, 115b with the first and second larger central panel 113a, 115a, respectively. In other words, the support tray 10 consists of an articulated parallelogram, or quadrilateral, comprising a frame, or mechanism, defined by the second side wall 15 with the second support leg 20, two cranks defined by the upper and lower transverse wall 11, 12, respectively, and a connecting rod defined by the first side wall 13 with the first support leg 19, wherein the passage from the flattened configuration to the upright configuration is achieved through a rotation of the two cranks.
[0070] With reference to fig. 13, another embodiment of a blank according to the present invention is described, indicated with reference number 110’, which is configured to make another version of the support tray of the present invention.
[0071] The elements of the blank 110’ common to the blank 110 described above are indicated by the same reference numbers.
[0072] In particular, the blank 110’ differs from the blank 110 on the shape of the second holes 26 made on the second main panel 112.
[0073] Each of the second holes 26 is encircled by the deformable flaps 28.
[0074] The shape of the deformable flaps 28 is such as to give each second hole 26 a multi-lobed or polygonal shape.
[0075] In the example shown, the shape of each hole 26 is tri-lobed. In other embodiments, not shown, a quadri-lobed shape can be provided, or even having a number of lobes other than three or four, for example two or five.
[0076] In the case of a multi-lobed shape, the different lobes are preferably connected by curved lines with curvature such as to be curved towards the center of the respective hole. In the case of a polygonal shape, the sides of the polygon are defined by broken lines in which the lines are oriented so as to define zones protruding towards the center at the median zone interposed between two edges.
[0077] In this embodiment, each deformable flap 28 has a curved portion 28a facing the center of the respective second hole 26 and is configured to be bent. Preferably, the curved portion 28a is defined by an arc of circumference having a center outside the respective second hole.
[0078] Preferably, each deformable flap 28 is convex, since they are curved towards the center of the hole.
[0079] The shape of the deformable flaps 28 is such that it is possible to define a circular area inside each second hole 26, having the aforementioned diameter D2.
[0080] The process for making the support tray 10 described heretofore comprises the following steps.
[0081] Initially, an initial shaping step can be provided in which the blank 110 is suitably shaped to make the support tray 10.
[0082] For example, the blank 110 can be supplied already with the first and second main panel 111, 112 provided with the first holes 25 and with the second holes 26, respectively, as defined above. Alternatively, in the shaping step, the first holes 25 can be made on the first main panel 111 and the second holes 26 can be made on the second main panel 112, in accordance with the embodiments described above.
[0083] In accordance with possible embodiments and / or operating variants, the process can comprise a first main folding step.
[0084] In this first main folding step the blank 110 is initially folded so that the first smaller central panel 113b contacts and is superimposed with an end portion of the first larger central panel 113a (fig. 6). Then, by means of the adhesive material Ml, the first smaller central panel 113b is glued and stably joined to the first larger central panel 113a, thus forming the first side wall 13.
[0085] Then, the blank 110 is folded so that the first and second main panel 111, 112 are arranged perpendicular to the first larger and smaller central panel 113a, 113b and parallel to each other so that the first holes 25 and the second holes 26 are axially aligned (fig. 7).
[0086] Thereafter, the blank 10 is folded so that the first side wall 13 folds inward to contact and be superimposed with the first main panel 111, consequently making obliquely translate both the second main panel 112, so that it contacts the first main panel 111, and also the second smaller central panel 115b so that it contacts and is superimposed with an end portion of the second larger central panel 115a (fig. 8).
[0087] Then, by means of the adhesive material Ml, the second smaller central panel 115b is glued and stably joined to the second larger central panel 115a, thus forming the second side wall 15.
[0088] We must clarify that, in relation to the type of adhesive material Ml, the gluing between the first larger and smaller central panel 113a, 113b and between the second larger and smaller central panel 115a, 115b can be achieved in different ways. For example, in the event that the adhesive material Ml is a heat-sealable material, the latter is suitably heated and, therefore, activated to guarantee that these central panels remain glued together.
[0089] The blank 110 is thus in a flattened configuration (fig. 8), wherein the first and second main panel 111, 112 are partially superimposed and in contact with each other, and the first and second smaller central panel 113b, 115b are connected and glued to the first and second larger central panel 113a, 115a.
[0090] In accordance with possible embodiments and / or operating variants, the process can provide that the blank 110 is fed already in this flattened configuration, to perform multiple folding operations thereon able to form a support tray 10.
[0091] The process comprises a shaping, or divaricating, step in which from the flattened configuration the blank 110 is suitably shaped with an oblique translational movement, to make it assume a suitable three-dimensional shape, that is, an upright configuration that determines the geometry of the support tray 10. In particular, the first and second main panel 111, 112, partially superimposed and in contact with each other, are separated from each other and spaced apart to bring each other in parallel, thus forming the upper and lower transverse wall 11 , 12 which, in this upright configuration, are perpendicular to the first and second side wall 13, 15. In this shaping step, the first holes 25 are aligned with the second holes 26 and the two support legs 19, 20 (fig. 9) are essentially formed which, in the flattened condition, are substantially horizontal and do not perform their function.
[0092] In accordance with preferred embodiments, the process comprises a second main folding step, or forming step, in which the larger and smaller side panels 116a, 116b and 117a, 117b of the blank 110 are folded to define the third and fourth side wall 16, 17, thus forming the support tray 10.
[0093] In this second main folding step, the first and second smaller side panel 116b, 117b are folded inwards, so that they are perpendicular to the lower transverse wall 12 and adjacent to the support legs 19, 20 (fig. 10). Subsequently, another adhesive material M2, possibly similar to the adhesive material Ml (fig. 11), is applied on the first and second smaller side panel 116b, 117b, already folded. Alternatively, the adhesive material M2 can be applied on an end portion of the first and second larger side panel 116a, 117a.
[0094] The first and second larger side panel 116a, 1 17a are then folded so that their end portion is superimposed with the already folded first and second smaller side panel 116b, 117b. Then, by means of the adhesive material M2, the first and second smaller side panel 116b, 117b are glued to the first and second larger side panel 116a, 117a, defining the third and fourth side wall 16, 17, respectively, and forming the other two support legs 21, 22 (fig. 12).
[0095] In this way, a support tray 10 is formed that is more stable and less subject to oscillations, deformations and / or flattening.
[0096] The process also comprises a preparation step, in which the support tray 10 is suitably prepared for the insertion of the elongated elements 200 through the first holes 25 of the upper transverse wall 11 and into the second holes 26 of the lower transverse wall 12.
[0097] In this preparation step, it is provided to drive deforming members, for example with a cylindrical or frustoconical shape, in number equal to the first holes 25 and having sizes such that it is possible to pass through them with little play.
[0098] In particular, the preparation step comprises a deformation step, in which the deforming members are axially aligned with the first holes 25 and then driven, passing through the latter, until engaging and deforming the deformable flaps 28 in order to define the second holes 26 of diameter D2, axially aligned with the first holes 25, in which to insert the elongated elements 200.
[0099] According to preferred embodiments, this deformation provides to elastically deform the deformable flaps 28 of the second holes 26 so as to adequately enlarge them for the insertion of the elongated elements 200.
[0100] This is particularly useful and advantageous in the case of flexible or deformable elongated elements 200, such as smoking articles or suchlike.
[0101] Then, in a subsequent insertion step, the elongated elements 200 are inserted in the support tray 10 passing through corresponding first holes 25 until engaging, with the respective lower end 201, the through openings generated by the deformation of the deformable flaps 28 that sustain a respective elongated element 200 by interference.
[0102] The process can comprise a packaging step, in which the support tray 10 is suitably inserted inside the containing body to form a box-shaped package.
[0103] It is clear that modifications and / or additions of parts may be made to the support tray 10 and to the process as described heretofore, without departing from the field and scope of the present invention, as defined by the claims.
[0104] For example, according to possible embodiments, in the event the support tray 10 comprises only two side walls 13, 15, once the shaping step has been carried out, the process comprises the preparing step, the inserting step and then the subsequent packaging step.
[0105] It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art will be able to achieve other equivalent forms of support tray, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
[0106] In the following claims, the sole purpose of the references in brackets is to facilitate their reading and they must not be considered as restrictive factors with regard to the field of protection defined by the claims.
