Description

RIGID SLIDE-OPEN PACKAGE FOR TOBACCO ARTICLES
TECHNICAL FIELD The present invention relates to a rigid slide-open package for tobacco articles .
The present invention may be used to particular advantage in a rigid cigarette packet, to which the following description refers purely by way of example. BACKGROUND ART
Rigid slide-open cigarette packets are known, such as those described in Patent Application FR-2499947-A3, Patent US-4534463-A1, and Patent US-5080227-A1. A rigid slide-open cigarette packet comprises a first container for housing a group of cigarettes wrapped in a sheet of foil, and which in turn is housed inside a second container so as to slide with respect to the second container between a closed position, in which the first container is fully inserted inside the second container, and an open position, in which part of the first container is extracted from the second container. Each container is substantially parallelepiped-shaped, and comprises two end walls; and a lateral surface bounded by the end walls and defined by lateral walls separated from one another by corresponding straight longitudinal edges. Though marketed, by being relatively easy to produce and generally popular with smokers, rigid slide-open cigarette packets of the above type call for a fairly large amount of packing material, and also have several drawbacks resulting from their non-anatomical shape, and their tendency to produce rapid wear of clothing item fabrics with which they come into contact. DISCLOSURE OF INVENTION
It is an object of the present invention to provide a rigid package for tobacco articles, designed to eliminate the aforementioned drawbacks, and which, in particular, is cheap and easy to produce. According to the present invention, there is provided a rigid slide-open package for tobacco articles; the package comprising a first container for housing the tobacco articles, and a second container for housing the first container in sliding manner, so as to allow the first container to slide with respect to the second container between a closed position, in which the first container is fully inserted inside the second container, and an open position, in which part of the first container is extracted from the second container; each container being substantially parallelepiped-shaped, and comprising two, respectively bottom and top, end walls, and a lateral surface bounded by the end walls and defined by lateral walls separated from one another by corresponding longitudinal edges, and separated from the end walls by corresponding transverse edges; the package being characterized in that at least one longitudinal edge or one transverse edge of at least one of the containers is a non-sguare edge.

BEST MODE FOR CARRYING OUT THE INVENTION Number 1 in the accompanying drawings indicates as a whole a rigid cigarette packet comprising a container 2 for housing a group 3 of cigarettes wrapped in a sheet of foil; and a container 4 for housing container 2 in sliding manner, so as to enable container 2 to slide with respect to container 4 between a closed position (Figure 1) , in which container 2 is fully inserted inside container 4, and an open position (Figure 2), in which part of container 2 is extracted from container 4.
As shown in Figure 3, container 4 is parallelepiped- shaped, and comprises a bottom end wall 5; a top end wall 6; and a lateral surface 7 bounded by end walls 5 and 6, and defined by two opposite, parallel major lateral walls 8, by a minor lateral wall 9 separated from major lateral walls 8 by two longitudinal edges 10, and by an open end 11 parallel to and opposite minor lateral wall 9 and for permitting passage of container 2 between said closed position (Figure 1) and said open position (Figure 2) . Lateral walls 8 and 9 of container 4 are separated from end walls 5 and 6 by transverse edges 12, which are divided into major transverse edges 12 between major lateral walls 8 and end walls 5 and 6, and minor transverse edges 12. Container 2 is parallelepiped-shaped, and comprises a bottom end wall 13; a top end wall 14: and a lateral surface 15 bounded by end walls 13 and 14, and defined by two parallel, opposite major lateral walls 16, and by two parallel, opposite minor lateral walls 17 separated from major lateral walls 16 by four longitudinal edges 18. Lateral walls 16 and 17 of container 2 are separated from end walls 13 and 14 by eight transverse edges 19, which are divided into four major transverse edges 19 between major lateral walls 16 and end walls 13 and 14, and four minor transverse edges 19 between minor lateral walls 17 and end walls 13 and 14.
Top end wall 14 of container 2 comprises an open portion 20, which also extends along part of major lateral walls 16, and permits removal of the cigarettes from container 2 when container 2 is in said open position (Figure 2) .
The four longitudinal edges 18 of container 2, and the two longitudinal edges 10 of container 4 are rounded, non-square edges, whereas the transverse edges 19 and 12 of containers 2 and 4 are all square. In an alternative embodiment not shown, one or more longitudinal edges 10 of container 4 and/or one or more longitudinal edges 18 of container 2 may be square . In a further embodiment not shown, some transverse edges 12 of container 4 and/or some transverse edges 19 of container 2 may be rounded, non-square edges, so as to have both rounded, non-square transverse edges 12 and/or 19, and rounded, non-square longitudinal edges 10 and/or 18.
When container 2 is in said closed position (Figure
1) , each lateral wall 8, 9 of container'' 4 obviously faces and is aligned with a corresponding lateral wall 16, 17 of container 2. More specifically, both containers 2 and 4 are sized to house group 3 of cigarettes and container
2 respectively with a small amount of clearance, thus minimizing the amount of packing material required to produce containers 2 and 4, and also minimizing movement of group 3 of cigarettes inside container 2, and of container 2 inside container 4. Obviously, a certain amount of clearance must be allowed between group 3 of cigarettes and container 2, and between container 2 and container 4, to permit easy withdrawal by the user of the cigarettes from container 2, and of container 2 from container 4 respectively.
Minor lateral wall 9 of container 4 has a hole 21
(Figure 3) shaped and sized to permit insertion of the user's finger, and which provides for assisting expulsion of container 2 from container 4, by the user applying pressure on minor lateral wall 17 of container 2 facing hole 21 when container 2 is in said closed position
(Figure 1) .
In an embodiment not shown, each major lateral wall 8 of container 4 has a recess close to open end 11 to assist extraction of container 2 from container 4 as of the closed position, by enabling the user to grip and exert pull on major lateral walls 16 of container 2. Packet 1 comprises stop means for limiting slide of container 2 with respect to container 4, and so preventing detachment of container 2 from container 4; which stop means are defined by two tongues 22 projecting from major lateral walls 16 of container 2, and by two tongues 23 projecting from major lateral walls 8 of container 4. Each tongue 22 projects outwards of container 2 from a respective major lateral wall 16 of container 2; each tongue 23 projects inwards of container 4 from a respective major lateral wall 8 of container 4, and is located close to open end 11 of container 4; and each tongue 22 is so located as to engage the corresponding tongue 23 as container 2 slides out of container 4, thus preventing detachment of container 2 from container 4. As shown in Figure 4, container 2 is formed from a corresponding flat blank 24, which is substantially in the form of an elongated rectangle, and the component parts of which are indicated, where possible, using the same reference numbers, with superscripts, as for the corresponding parts of container 2.
Blank 24 comprises two groups 25 of longitudinal crease lines 26, and a number of transverse crease lines 27 defining, between the two groups 25 of longitudinal crease lines 26, a panel 14' forming part of top end wall 14; a panel 16' forming one major lateral wall 16; a panel 13' forming bottom end wall 13; a panel 16" forming the other major lateral wall 16; and a panel 14" forming part of top end wall 14. Panel 16' comprises two wings 17', which are located on opposite sides of panel 16', are separated from panel 16' by the two groups 25 of longitudinal crease lines 26, and form respective outer portions of minor lateral walls 17; and panel 16" comprises two wings 17", which are located on opposite sides of panel 16", are separated from panel 16" by the two groups 25 of longitudinal crease lines 26, and form respective inner portions of minor lateral walls 17. Wings 17" are connected to a further two wings 13", which form respective inner portions of bottom end wall 13; and each group 25 of longitudinal crease lines 26 comprises a number of longitudinal crease lines 26, and forms two rounded longitudinal edges 18 of container 2.
As shown in Figure 5, container 4 is formed from a corresponding flat blank 28, which is substantially in the form of a rectangle, and the component parts of which are indicated, where possible, using the same reference numbers, with superscripts, as for the corresponding parts of container 4. Blank 28 comprises two transverse crease lines 29, and a number of longitudinal crease lines 30 defining, between the two transverse crease lines 29, a panel 8' forming one major lateral wall 8; a panel 9' forming minor lateral wall 9; and a panel 8" forming the other major lateral wall 8. More specifically, panel 9' is separated from panels 8' and 8" by two groups 31 of longitudinal crease lines 30. Panel 8' comprises two wings 5' and 6' , which are located at opposite ends of panel 8' , are separated from panel 8' by transverse crease lines 29, and form respective outer portions of end walls 5 and 6; panel 9' comprises two wings 5" and 6", which are located at opposite ends of panel 9' , are separated from panel 9' by transverse crease lines 29, and form respective inner portions of end walls 5 and 6; and panel 8" comprises two wings 5"' and 6"', which are located at opposite ends of panel 8", are separated from panel 8" by transverse crease lines 29, and form respective inner portions of end walls 5 and 6. As shown in Figures 3 and 5, wings 5" and 6" and wings 5"' and 6"' are so shaped as not to overlap when folded onto wings 5' and 6' to define end walls 5 and 6 of container 4. Each group 31 of longitudinal crease lines 30 comprises a number of longitudinal crease lines 30, and forms a respective rounded longitudinal edge 10 of container 4.
In the embodiment shown in Figures 6 and 7, the transverse dimension (i.e. parallel to major transverse edges 12) of major lateral walls 8 of container 4 is smaller than the corresponding transverse dimension (i.e. parallel to major transverse edges 19) of major lateral walls 16 of container 2, so that container 4 does not cover the two longitudinal edges 18 of container 2 facing open end 11 of container 4 when container 2 is in said closed position (Figure 6) . Figure 8 shows the blank 28 required to produce container 4 in Figures 6 and 7, and which is identical to blank 28 in Figure 5. In the Figure 9 embodiment, longitudinal edges 10 of container 4 and longitudinal edges 18 of container 2 are bevelled non-square edges; in which case, each group 31 of longitudinal crease lines 30 in blank 28 comprises two longitudinal crease lines 30, and each group 25 of longitudinal crease lines 26 in blank 24 comprises two longitudinal crease lines 26.
In the Figure 10 embodiment, each major lateral wall 16 of container 2 has an outwardly convex profile, is connected to each minor lateral wall 17 along a sharp longitudinal edge 18, and subtends a substantially obtuse dihedral angle with each minor lateral wall 17. Each major lateral wall 16 of container 2 in Figure 10 comprises a flat central portion, and two lateral crease strips with longitudinal crease lines; and each lateral strip is curved with its concavity facing inwards to connect the central portion to the corresponding minor lateral wall 17, and subtends a substantially obtuse dihedral angle with said minor lateral wall 17. Each end wall 13, 14 is substantially rectangular, and has bevelled corners to adapt to the outwardly convex profile of major lateral walls 16.
Each major lateral wall 8 of container 4 in Figure 10 has an outwardly convex half-profile, is connected to minor lateral wall 9 along a sharp longitudinal edge 10, and subtends a substantially obtuse dihedral angle with minor lateral wall 9. More specifically, each major lateral wall 8 of container 4 in Figure 10 comprises a flat central portion, and a lateral crease strip with longitudinal crease lines; the lateral strip is curved with its concavity facing inwards to connect the central portion to minor lateral wall 9, and subtends a substantially obtuse dihedral angle with minor lateral wall 9. Each end wall 5, 6 is substantially rectangular, and has two bevelled corners to adapt to the outwardly convex half-profile of major lateral walls 8.
The Figure 10 embodiment recalls the cigarette packet described in Patent Application EP-A1-1066206, which comprises an outwardly convex front and rear wall, each of which has a flat central portion, and two curved lateral crease strips connecting the flat central portion to two flat lateral walls of the packet along respective sharp longitudinal edges . In the Figure 11 embodiment, each major lateral wall 16 of container 2 has an outwardly convex profile, is connected to each end wall 13, 14 along a sharp transverse edge 19, and subtends a substantially obtuse dihedral angle with each end wall 13, 14. More specifically, each major lateral wall 16 of container 2 in Figure 11 comprises a flat central portion, and two lateral crease strips with transverse crease lines; each lateral strip is curved with its concavity facing inwards to connect the central portion to the corresponding end wall 13, 14, and subtends a substantially obtuse dihedral angle with said end wall 13, 14. Each minor lateral wall 17 is substantially rectangular, and has bevelled corners to adapt to the outwardly convex profile of major lateral walls 16.
Each major lateral wall 8 of container 4 in Figure 11 has an outwardly convex half-profile, is connected to each end wall 5, 6 along a sharp transverse edge 12, and subtends a substantially obtuse dihedral angle with end wall 5, 6. More specifically, each major lateral wall 8 of container 4 comprises a flat central portion, and two lateral crease strips with transverse crease lines; each lateral strip is curved with its concavity facing inwards to connect the central portion to end wall 5, 6, and subtends a substantially obtuse dihedral angle with end wall 5, 6. Minor lateral wall 9 is substantially rectangular, and has bevelled corners to adapt to the outwardly convex half-profile of major lateral walls 8. The Figure 11 embodiment recalls the cigarette packet described in Patent Application IT-BO01A000584, which comprises an outwardly convex front and rear wall, each of which comprises a flat central portion, and two curved lateral crease strips connecting the flat central portion to two flat end walls of the packet along respective sharp transverse edges .
Clearly, changes may be made to packets 1 as described above, such as replacing the convex with partly convex walls, or forming only one as opposed to two opposite facing convex walls .
In the Figure 12 embodiment, longitudinal edges 10 of container 4 and longitudinal edges 18 of container 2 are square edges, and the major transverse edges 12 of container 4 and the major transverse edges 19 of container 2 are rounded non-square edges. The major transverse edges 12 of container 4 and the major transverse edges 19 of container 2 may, of course, be bevelled non-square edges. The Figure 12 embodiment recalls the cigarette packet described in Patent Application EP-A1-0764595, which is substantially parallelepiped-shaped and comprises at least one bevelled transverse edge. In packets 1 in Figures 11 and 12, each major lateral wall 8 of container 4 has a recess close to open end 11; which recesses provide for assisting extraction of container 2 from container 4 as of the closed position, by enabling the user to grip and exert pull on major lateral walls 16 of container 2, as well as for exposing part of major lateral walls 16 of container 2 when container 2 is in said closed position.
Tests have shown that cigarette packets 1 as described above reduce wear of clothing item fabrics with which packets 1 come into contact in use, while the anatomical shape of the packets provides for easy handling by the user. Moreover, cigarette packets 1 as described above call for less packing material than equivalent square-edged packets .
Given the numerous advantages of cigarette packets 1 as described above, the form of packets 1 may also be applied completely to the manufacture of other types of rigid containers for tobacco articles, such as cartons of packets of cigarettes, or cigar packets.
