Abstract

A packet filled with articles (2) of elongated shape comprises a substantially parallelepiped outer wrapper (7) presenting a front wall (8), a rear wall or back (9), two flank walls (10), a top (11) and a base (12), and scored or punched with a cutout (13) delimiting a closure flap (17); the cutout (13) appears as transverse line occupying a central area of the front wall (8), and two lines extending from the ends of the transverse line, at a predetermined distance from the corner edges of the relative flank walls (10), along the front wall (8) and at least across the width of the top (11). The area of the wrapper (7) occupied by the cutout (13) is covered by an adhesive label (19) furnished with a pull tab (20). The packet (1) comprises an inner element (21) serving to fill two longitudinal and substantially parallelepiped spaces within the wrapper (7), each coinciding positionally and dimensionally at one end with a relative portion of the top (11) lying outside the line of the cutout (13).

Description

The present invention relates to a packet for articles of elongated shape such as cigarettes, for example, or sticks of chewing gum, or pouches of smokeless tobacco (snus).
Packets or wrappers of the type in question are fashioned from substantially rectangular leaves of pliable packaging material, generally affording a high degree of impermeability to air and moisture, and appear substantially parallelepiped in shape, presenting a rectangular section.
The packet is delimited by four side walls extending parallel to the longitudinal axis of the parallelepiped, namely a front wall, a rear wall or back, and two narrow walls or flanks, also by two walls disposed transversely to the selfsame axis, the one upwardly directed, identifiable as a top, the other downwardly directed, identifiable as a base.
Certain packets of this type provide the subject matter of US Patent 4,300,676 , which discloses and depicts packets containing cigarettes, inserted into cardboard outer wrappers of the type appearing as a box with a hinged lid.
The cigarettes in the packet are disposed alongside one another, and parallel to the aforementioned longitudinal axis.
The topmost part of the packet presents a cutout substantially of letter "U" outline, including an arcuate central portion occupying the front wall, and two parallel portions extending from the ends of the arcuate portion along the front wall, across the top and onto the uppermost part of the back.
The cutout delimits a closure element on the wrapper, resembling a flap or tongue, positioned over an opening through which the user can draw out an article contained in the packet by taking hold of one end and pulling.
The closure element and an area around the selfsame element are covered completely by an adhesive label that extends across an area including a top portion of the front wall, the top of the packet, and an adjoining portion of the back.
The part of the label positioned on the front wall is furnished with a tab that both facilitates the operation of pulling back the tongue and allows the user to reclose the packet each time a cigarette, or other article, is taken from the packet.
Importantly, in order to ensure that the adhesive label will cover the entire area occupied by the cutout completely, and consequently guarantee an airtight closure of the wrapper, the parallel portions of the cutout are placed at a predetermined distance from the corner edges along which the front wall, the top and the back of the packet are joined to the two flanks.
This means that when the closure element is pulled back, the top of the packet will not be raised in its entirety to expose the top ends of all the articles contained in the packet, as would be the case, conversely, when a conventional hinge-lid packet is opened.
As a result, the articles of which the top ends are positioned at the two ends of the top, lying outside the line of the cutout, are not exposed to view; moreover, given that the contents of the packet are generally enveloped by the wrapper in a tight fit, these same endmost articles can prove difficult to access and extricate.
The object of the present invention is to provide a packet for articles of elongated shape such as will enable all of the articles contained in the selfsame packet to be removed without the drawbacks typical of prior art packets as described above, and which also affords cost advantages compared to conventional hinge-lid packets.
The stated object is realized, according to the present invention, in a packet for articles of elongated shape as recited in the appended claims.
The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which:

With reference to figures 1, 2, 3 and 6, numeral 1 denotes a packet, in its entirety, serving to contain a group of articles 2, arranged side by side and disposed parallel to a longitudinal axis A of the selfsame packet 1.
In the example of figure 3, the articles 2 are shown as cigarettes 3 arranged in three layers 4, whereas in the example of figure 6, the packet 1 contains a group of cigarettes 3 arranged in two layers 4. As will become clear in due course, the articles 2 in question might also consist, for example, in sticks 5 of chewing gum (see figure 13) or pouches 6 of smokeless tobacco (see figure 11).
The packet 1, which is manufactured on a cigarette packer or other packaging machine (not illustrated), comprises an outer wrapper 7 substantially of parallelepiped appearance and rectangular section, made from a pliable material affording a high degree of impermeability to air and moisture, and typically heat-sealable.
The wrapper 7 is delimited by four side walls, extending parallel to the longitudinal axis A, comprising a front wall 8, a rear wall or back 9 and two narrower walls or flanks 10, also by two walls disposed transversely to the selfsame axis A, one upwardly directed, identifiable as a top 11, the other downwardly directed, identifiable as a base 12.
The top part of the wrapper 7 presents a cutout 13 substantially of letter "U" outline, including a central portion 14 that occupies the front wall 8, and two parallel portions 15 extending from the ends of the central portion 14 across the front wall 8, the top 11, and the uppermost part of the back 9.
On the back 9 of the wrapper, the two free ends of the parallel portions 15, denoted 16, are curled in toward one another.
The U-shaped cutout 13 delimits a closure element, or tongue 17, complementary to an opening 18 through which the articles 2 are taken from the packet 1.
The part of the wrapper 7 presenting the cutout 13 is covered by an adhesive label 19, of which the part positioned over the front wall 8 is furnished with a tab 20 designed to facilitate the operation of pulling back the tongue 17 when the packet 1 is opened.
The packet 1 also comprises an inner element 21 of stiff or semi-stiff paper material, interposed between the articles 2 and the outer wrapper 7, presenting a flat central portion 22 breasted in contact with the front wall 8 and of similar height and width dimensions (see also figures 15 and 16).
The inner element 21 presents a rib 23 along each longitudinal edge, of depth substantially equal to the depth of the wrapper 7, and more exactly to the transverse dimension presented by the flanks 10 of the packet 1. Accordingly, the ribs 23 occupy two substantially parallelepiped spaces internally of the wrapper 7, each coinciding cross-sectionally with a portion of the top 11 lying between the cutout 13 and the flank 10.
Referring also to figure 4, the inner element 21 is fashioned from a flat blank 24 appearing substantially rectangular in general outline, configured symmetrically relative to a longitudinal axis, denoted A', and divided by longitudinal and transverse crease lines into a plurality of panels.
More exactly, the blank 24 is divided by four longitudinal crease lines 25, 26, 27 and 28, on two opposite sides of a central panel 29, into respective second, third and fourth panels denoted 30, 31 and 32, and respective end flaps denoted 33.
Finally, a single crease line denoted 34 extends transversely to the axis A' across one end of the central panel 29, delimiting a bottom flap 35 that will be breasted in contact with the base 12 of the assembled packet 7.
The edge 36 of the central panel 29 remote from the bottom flap 35 might present a U-shaped cutaway 37, designed to facilitate the removal of the articles 2 from the packet 1, in which case the two end flaps 33 likewise will present respective complementarily shaped cutaways 38.
The process whereby the panels and flaps of the flat blank 24 are bent along the respective crease lines to form the inner element 21, in a succession of folding steps, will be readily discernible from the drawings.
In particular, along each of the two longitudinal edges delimiting the central panel 29, the adjoining panels 30, 31 and 32 combine with a portion of the selfsame central panel 29 to form the longitudinal walls of one of the aforementioned ribs 23; more exactly, the second panel 30 becomes an outer wall breasted in contact with the relative flank 10 of the wrapper 7, the third panel 31 becomes a wall breasted in contact with the back 9, and the fourth panel 32 becomes a wall directed toward the inside of the packet 1, offered in contact to the articles 2.
Once bent into shape, the inner element 21 is secured by affixing the two end flaps 33 to the central panel 29 with an adhesive, in such a way that the thickness of the aforementioned flat central portion 22 will be doubled.
The inner elements 21 are supplied to the packaging machine aforementioned as flat blanks stacked one on top of another (see figure 14) and, at the moment of their assembly with the wrapper 7, subjected to a forming operation causing them ultimately to assume the configuration illustrated in figures 15 and 16.
Figure 5 illustrates a blank 39 differing from the blank 24 described previously in that it comprises a further panel 40, joined along a further transverse crease line 41 to the bottom flap 35, on the side opposite from the central panel 29.
One face of the panel 40 in question is designed to engage in contact with the back 9 of the wrapper 7, and the other face with the third panels 31 of the two ribs 23.
Another difference between the blank 39 of figure 5 and the blank 24 of figure 4 is that the two third panels 31 are furnished, at the ends adjacent to the additional panel 40, with respective appendages 42 substantially of L-shaped outline.
When bent at right angles to the two respective panels 31, these same appendages 42 provide closure elements for corresponding open ends presented by the ribs 23 of the inner element 21.
Figure 6 illustrates a packet 1 designed to accommodate two layers 4 of cigarettes 3, of which the blank 44, shown in figure 7, differs from the blank 39 of figure 5 in that the additional panel 40 is furnished with two lateral flaps 45, delimited by respective crease lines 46, that will be breasted with the flanks 10 of the outer wrapper 7.
Furthermore, the free end of the panel 40 presents a cutaway 37 designed to facilitate the removal of the artikel 2.
Figures 8 and 9 illustrate a packet 1 containing pouches 6 of smokeless tobacco (snus) stacked on edge and disposed parallel to the front and rear walls 8 and 9.
The relative blank 47 illustrated in figure 10 differs materially from the blank 44 of figure 7 only in that the cutaways 37 of the panels 40 and 29 are of dissimilar dimensions, and not aligned axially one with another.
Figure 11 illustrates a further packet 1 containing pouches 6 of tobacco, stacked on edge and disposed transversely to the front and rear walls 8 and 9.
The relative blank 48, illustrated in figure 12, is substantially similar to the blank of figure 10.
Figure 13 illustrates a packet 1 holding sticks 5 of chewing gum, stacked on edge and disposed transversely to the front and rear walls 8 and 9.
Self-evidently, in a packet 1 furnished with the inner element 21 described and illustrated, the problems connected with accessing and extracting the articles located nearest to the flank walls of the wrapper are overcome entirely.
It will be appreciated also that the quality and strength of the packet can be determined selectively, on the basis of the type of blank utilized to fashion the inner element 21.
The position of the inner element 21 within the wrapper 7 might equally well be rotated through 180° about the longitudinal axis A' from the position illustrated in the accompanying drawings, that is to say with the flat central portion 22 offered in contact to the back 9 of the wrapper 7.
