Definitions

  • the present invention is part of the technical sector of packets for smoking articles.
  • the invention relates to a method for producing a packet of smoking articles and to a packet obtained by this method.
  • Smoking articles are, for example, cigarettes, to which reference will be made explicitly, exclusively by way of example, in the following discussion.
  • a packet of cigarettes of the known type comprises an outer envelope consisting of a rigid or soft cardboard container, which is provided with an opening for extracting cigarettes.
  • the cigarettes, arranged in the container, are generally wrapped in a wrapping material.
  • the outer envelope can be provided with a cover that closes the container, which may have different shapes and can be, for example, hinged to the container, slidable or rotatable with respect to the container, or completely released from the container, or arranged according to other different methods. All these variations are dictated, above all, by the rapid changes in the market, which frequently require packet manufacturing companies to change the appearance of the outer envelope (container and/or cover), to follow consumers' preferences.
  • the different conformation of the outer envelope (container and/or possible cover) of the packets does not always allow easy adoption of the optimal arrangements to maintain the aroma and quality of the cigarettes contained in the package unaltered.
  • the object of the present invention is to overcome the aforesaid drawbacks.
  • This object is achieved by proposing a method for producing a packet of smoking articles, a plant that implements the method, and a packet of smoking articles obtained with this method, in accordance with the attached claims.
  • the proposed invention allows the production of a packet of smoking articles which, independently of the presence or the conformation of an outer envelope (container and/or cover), is able to maintain the aroma unaltered, and the quality of the articles themselves, over time. Furthermore, the invention is simple to make and particularly versatile, as will be made clearer in the following description.
  • Figure 1 illustrates a group of smoking articles, specifically cigarettes
  • Figure 2 illustrates a plan view of a wrapping sheet, which is part of the packet according to the invention, in which possible bending lines to be made thereon are illustrated, by way of example;
  • Figure 3 illustrates a perspective view of a packet of smoking articles according to the present invention, in which some parts have been removed to better highlight others;
  • Figure 4 illustrates a perspective view of the packet of Figure 3, in which some parts have been removed to better highlight others;
  • Figure 5A illustrates a plan view of a sheet of heat-sealable material, part of the packet according to the invention, in which an opening has been made according to the method according to the invention
  • Figure 5B illustrates a plan view of an adhesive label comprising a layer of additional material, part of the packet according to the invention
  • Figure 5C shows a view similar to that of Figure 5 A, in which the adhesive label of Figure 5B is applied onto the opening of the sheet of heat-sealable material, according to the method according to the invention;
  • Figure 6 is a perspective view of a packet according to the invention, with a different degree of detail with respect to the packet of Figure 3;
  • Figure 7 shows a perspective view of a packet according to the invention, in a preferred embodiment of the invention, following a different packaging operating step with respect to the package of Figure 6;
  • Figure 8 A illustrates a plan view of a blank for making a frame, part of the packet according to the invention, in a first variant
  • Figure 8B illustrates a plan view of a packet made with the frame of Figure 8 A;
  • Figure 8C illustrates an enlarged view of the detail X of
  • Figures 9A, 9B, 9C illustrate as many analogous views to those of Figures 8A, 8B, 8C, respectively, according to a second variant; in particular, Figure 9C illustrates an enlarged view of the detail Y of Figure 9B;
  • Figure 10A shows a plan view of a blank for making a frame, part of the packet according to the invention, in a third variant
  • the invention relates to a packet 1 of smoking articles, illustrated by way of example in Figures 3, 4, 6, 7, according to different degrees of detail/embodiments .
  • a packet 1 of smoking articles comprises: a group 2 of smoking articles (for example, cigarettes, illustrated in Figure 1); a wrapper 3, which comprises a layer of a first material Ml, and which wraps the group 2 of smoking articles so that the aforementioned layer of the first material Ml faces the smoking articles.
  • the wrapper 3 (visible, for example, in Figure 2 in the extended configuration, and in Figure 3 while wrapping the smoking articles) is shaped so as to identify an opening 31 for extracting the smoking articles (see Figure 3).
  • Figure 2 illustrates, with dashed lines, by way of example, possible lines LI for bending the wrapper.
  • the packet 1 also comprises a containment frame 4 wrapped around the wrapper 3, so as to contain the group 2 of smoking articles and the wrapper 3, forming a semi-finished unit 5 (see Figure 4).
  • the frame 4 (visible, for example, in Figure 8A and 9A in an extended configuration, in two different variants, and in Figure 4 while it wraps around the wrapper 3) comprises an open zone 40 arranged at the opening 31 of the wrapper 3, for extracting the smoking articles.
  • the frame 4 and the wrapper 3 are mutually dimensioned so that an edge of the wrapper 3 (in particular, the edge 300, with reference to the extended wrapper of Figure 2) protrudes (though minimally) through the open zone 40 of the frame 4.
  • the packet 1 also comprises an envelope 6 (see Figure 6) of a second material M2, different from the first material Ml, which is a heat-sealable material with a barrier effect (also called “sealed", i.e. a material capable of forming a barrier to external agents, such as humidity, which could degrade the quality of the smoking articles, in particular, their aroma);
  • the envelope 6 contains the semi-finished unit 5 and is provided with at least one opening 1, arranged at the aforementioned opening 31 of the wrapper 3 for extraction (the envelope 6 is visible in an extended configuration, in Figures 5A and 5C, and in Figures 6 and 7 while it wraps around the semi-finished unit 5).
  • Figures 5A and 5C illustrate, by way of example, possible bending lines L2 to be made thereon.
  • the packet 1 further comprises an adhesive label 7 positioned on the envelope 6 so as to cover the opening 61;
  • the adhesive label 7 (visible singly in Figure 5B, and fixed to the sheet of heat-sealable material in Figures 5C and 7), comprises a first surface comprising (or preferably formed by) a layer of the aforementioned first material Ml facing the group 2 of smoking articles.
  • the layer of first material Ml does not extend over the entire first surface of the label 7.
  • the entire first surface of the label 7 consists of the layer of first material Ml.
  • the packet 1 proposed above has a simple structure and, at the same time, makes it possible to maintain the aroma and quality of the smoking articles unchanged over time.
  • the proposed packet 1 is particularly versatile because it can also be implemented with a container 8 of any type and a possible cover 9 (as will be explained below).
  • the presence of the opening 31 for extracting the smoking articles in the envelope 3 facilitates the opening of the adhesive label 7.
  • wrappers of the known art completely wrap around the smoking articles and comprise a removable tear-off portion (by means of a pre-fracture or pre-cutting line, not visible in the attached figures), which can be torn by a user at the first opening of the packet, for access to smoking articles.
  • This removable portion is not only impractical, but, moreover, since it is essentially a flap of material partially free to move, it can negatively interfere with the adhesive label.
  • the fact that the label 7 comprises a layer of the first material Ml in such a way as to face the group 2 of smoking articles respects some recent regulations concerning packaging products.
  • the first material Ml is paper.
  • the wrapper 3 further comprises a layer of a third material M3, which is different from the first material Ml, and which is coupled to the layer of first material Ml.
  • the third material M3 is aluminum (see Figure 3).
  • the wrapper 3 with which the group 2 of smoking articles is wrapped is a sheet of metallized paper (also called “silver paper” or “foil”), or rather, a non-heat-sealable material.
  • the wrapper 3 consists of a coupled material comprising aluminum, different from the "foil” paper.
  • the label 7 is made of a multilayer material, comprising, for example, aluminum (or rather, it is a coupled material comprising aluminum) (which may form the first material Ml) or comprises metallized paper (the paper may form, for example, the first material Ml).
  • the second material M2 of which it is made is an opaque thermoplastic material, i.e. which does not let light pass.
  • the thermoplastic material of which envelope 6 is made is a reflective opaque thermoplastic material, i.e. capable of reflecting light.
  • the opening 61 of the envelope 6 of heat-sealable material is preferably obtained by the removal of material in the envelope 6 itself (or rather, a "window", obtained from a notch that extends along a closed profile), as shown in Figure 5A.
  • the envelope 6 shown in Figure 6 (and partially in Figure 7) has, on both sides, respective flaps 610, 62 folded one on top of the other and then sealed.
  • the envelope 6 also has a weld that is fixed onto the lower side, not visible in the attached figures.
  • the envelope can have, also laterally, two opposed and fixed welds, as described in the international publication WO2015136510.
  • the adhesive label 7 is fixed to the envelope 6 of heat-sealable material to cover (and close) the opening 61 by means of a repositionable adhesive (or a sticky substance) (also called “weak glue” or “glue that does not dry out”), which is applied to the first surface of the adhesive label 7, in particular, all around the opening for extracting the smoking articles to allow the label 7 to be partially separated several times from the envelope 6 of heat-sealable material (that is, at each opening of the packet 1) and then fixed again non-permanently to the envelope 6. Specifically, the adhesive does not affect, or rather, is not applied to the layer of first material Ml which faces the group 2 of smoking articles.
  • the adhesive label 7 can be provided with a tongue 70 lacking repositionable adhesive, which can be gripped by a user to facilitate lifting of the adhesive label 7 for access to the smoking articles (see Figures 5B, 5C and 6).
  • the label 7 can be provided with permanent glue at the relative rear portion, opposite the tongue (70), to prevent complete removal of the label 7 from the envelope 6.
  • the packet 1 can also comprise a container 8, which contains the barrier-like ("sealed") envelope 6, and which is provided with an opening 80 (indicated only in a generic way in Figure 7).
  • the container 8 is preferably made of rigid cardboard.
  • the container 8 is, for example, made of plastic or metallic material.
  • the opening 80 of the container 8 is arranged at the label 7 of the envelope 6 to allow access to the smoking articles, and the packet 1 also comprises a cover 9 hinged to the container 8, rotatable to open and close the opening 80 of the container 8.
  • the cover 9 is, for example, made of a single body with the container 8, it is also made of rigid cardboard (or, in any case, of the same material with which the container 8 is made) and can be shaped like a cup (still referring to figure 7) ⁇
  • the adhesive label 7 of the envelope 6 is bound to the cover 9, so that rotating the cover 9 with respect to the container 8 simultaneously moves the adhesive label 7 (as illustrated in Figure 7).
  • This embodiment is particularly practical for the user, who can rotate the cover 9 and, in a single gesture, lift (or reposition) the adhesive label 7.
  • the packet can further comprise a container (for example, made of rigid cardboard), which contains the barrier-effect envelope, and which is provided with an opening, arranged in such a way as to allow the (at least partial) exit through the opening, by rotation or translation, of the semi-finished unit wrapped by the envelope from the container, allowing access to the smoking articles.
  • a container for example, made of rigid cardboard
  • the opening of the container can be arranged at a side wall or on the upper wall of the container (considering the orientation of the packet in use).
  • the packet subject of the invention is suitable for any production and/or technical need, since it can be without a container 8, or it can comprise a container 8 of different conformation and a possible cover 9.
  • the packet 1 comprises a container 8 and a possible cover 9, as in the embodiments described above, in order to preserve the aroma and the quality of the smoking articles over time, it is not necessary to provide, outside the container 8 and the possible cover 9, a layer of transparent thermoplastic material, as is the case with known solutions.
  • the containment frame 4 is a blank 41 made of inner packaging material (provided with suitable folding lines PI, indicated - by way of example - in Figures 8A and 9A with dashed lines, and made according to known methods), for example cardboard, which defines an open zone 40 to allow access to smoking articles (shown in Figure 4).

  • the containment frame 4 has a box-like shape which, for example, has six walls, to define a parallelepiped shape.
  • the open zone 40 for example, partially involves the front wall and partially involves the upper wall of the frame 4, or rather, those walls arranged at the adhesive label 7 when the packet 1 is closed.
  • this embodiment is particularly robust.
  • the containment frame 4 preferably comprises the portions 42, 43, 44, 45 (or flaps), which are overlapped two by two to contain the wrapper 3 with the group 2 of smoking articles inside it; these overlapped portions 42, 43, 44, 45 (indicated for greater clarity in Figures 8 A, 9A and 10 relative to the blank 41, as will be made clear below) may be bound together to stabilize the frame 4 itself, for example, they may be glued on top of each other.

  • the overlapped portions 42, 43, 44, 45 are at least partially plastically deformed, for example, by punching, to reduce the overall thickness of the overlapped portions 42, 43, 44, 45.
  • both of the embodiments described above facilitate extraction of the smoking articles from the packet 1, since the deep- drawing/different transverse development of the overlapped portions 42, 43, 44, 45 reduces the compression force of the frame 4 on the smoking articles.
