RIGID PACKAGE FOR TOBACCO ARTICLES
TECHNICAL FIELD The present invention relates to a rigid package for tobacco articles .
In the following description, reference is made, for the sake of simplicity, to rigid packets of cigarettes, though this in no way detracts from the general scope of the present invention. BACKGROUND ART
A rigid packet of cigarettes normally comprises a cup-shaped bottom container housing a group of cigarettes and having an open top end; and a cup-shaped top lid hinged to the bottom container along a hinge to rotate, with respect to the bottom container, between an open .-and a closed position respectively opening and closing the open end. In the closed position, the lid imparts to the packet of cigarettes a substantially rectangular parallelepiped shape defined by a lateral surface, and by two flat, identical, respectively top and bottom, end walls, which bound the lateral surface, and are parallel to and facing each other.
Though widely used, by being fairly easy to produce and popular with smokers, rigid packets of the above type have been found to lose their shape during normal use, fail to provide adequate protection for the cigarettes inside, and are not always easy to open, particularly when deformed.
DISCLOSURE OF THE 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 package for tobacco articles, comprising a first container housing the tobacco articles and having a top lid, which is hinged along a lid hinge, formed in a rear wall, to rotate between an open position and a closed position respectively opening and closing the first container; the rigid package being characterized by comprising a second container having a front opening and housing the first container so that a front wall of the first container, opposite the rear wall, is positioned facing the front opening; the first container being connected to the second container by a first hinge between the second container and the top lid of the first container, and by a second hinge between the second container and a bottom portion of the first container.

Number l in the accompanying drawings indicates as a whole a rigid package for tobacco articles, defined by a rigid packet of cigarettes containing an orderly,
parallelepiped-shaped group 2 of cigarettes 3 wrapped in a sheet of foil wrapping material (not shown for the sake of clarity) .
Packet 1 comprises a container 4 housing the orderly group 2 of cigarettes 3 and substantially in the form of a commonly marketed rigid, hinged-lid packet of cigarettes . More specifically, container 4 comprises a cup-shaped bottom container 5 having an open top end 6; and a cup-shaped top lid 7 hinged to bottom container 5 along a hinge 8 to rotate, with respect to bottom container 5, between an open position (Figure 2) and a closed position (Figures 1 and 3) respectively opening and closing end 6.
In the closed position, lid 7 imparts to container 4 a rectangular parallelepiped shape defined by a lateral surface 9, and by two flat, identical, respectively top and bottom, end walls 10 and 11, which bound lateral surface 9, and are parallel to and facing each other.
Lateral surface 9 comprises two flat, facing, parallel minor lateral walls 12, and two flat, facing major lateral walls 13, 14 crosswise to minor lateral walls 12. More specifically, one major lateral wall 13 defines a front wall of container 4, while the other major lateral wall 14 defines a rear wall of container 4. Container 4 also comprises a collar 15, which is folded into a U and glued to the inside of cup-shaped container 5 so as to project partly outwards of end 6 and engage a corresponding inner surface of lid 7 when lid 7
is in the closed position.
Four longitudinal edges 16 are defined between minor lateral walls 12 and major lateral walls 13, 14; and eight transverse edges 17, perpendicular to longitudinal edges 16, are defined between end walls 10, 11 and lateral walls 12, 13, 14. More specifically, the eight transverse edges 17 are divided into four minor transverse edges 17, i.e. bounding minor lateral walls 12, and four major transverse edges 17, i.e. bounding major lateral walls 13, 14.
Rigid packet 1 of cigarettes comprises a further container 18, which is parallelepiped-shaped and in the form of a box having a front opening 19. More specifically, container 18 comprises a rear wall 20 opposite and facing front opening 19; two flat, identical, respectively top and bottom, end walls 21 and
22 perpendicular to rear wall 20 and parallel to and facing each other; and two flat, identical lateral walls
23 perpendicular to rear wall 20 and parallel to and facing each other.
Two longitudinal edges 24 are defined between rear wall 20 and lateral walls 23; two major transverse edges
25, perpendicular to longitudinal edges 24, are defined between rear wall 20 and end walls 21, 22; and four minor transverse edges 25, perpendicular to longitudinal edges
24 and to major transverse edges 25, are defined between lateral walls 23 and end walls 21, 22.
Container 18 has substantially the same dimensions
as container 4, which is housed inside container 18 so that front wall 13 of container 4 faces front opening 19 of container 18; rear wall 20 of container 18 is substantially parallel to and facing rear wall 14 of container 4; each end wall 21, 22 of container 18 is substantially parallel to and facing a corresponding end wall 10, 11 of container 4; and each lateral wall 23 of container 18 is substantially parallel to and facing a corresponding minor lateral wall 12 of container 4. In actual use,' packet 1 may assume a closed configuration (Figures 1 and 3-7) in which container 4 is housed entirely inside container 18, and an open configuration (Figures 2 and 9) in which container 4 is partly extracted from container 18. Container 4 is connected to container 18 by a hinge 26 between container 18 and lid 7 of container 4, and by a hinge 27 between container 18 and a bottom portion of container 4. More specifically, hinge 26 is defined by a flexible strip 28 connected firmly to lid 7 of container 4, at front wall 13, and to end wall 21 of container 18; and hinge 27 is defined by a flexible strip 29 connected firmly to front wall 13 of container 4 and to end wall 22 of container 18.
The position of the axis of rotation of hinge 26 is movable with respect to container 18 in a direction crosswise to the axis of rotation itself, by flexible strip 28 comprising an end portion 31 connected firmly to lid 7 of container 4, at front wall 13; an opposite end
portion 30 connected firmly to end wall 21 of container 18; and a free intermediate portion 32 not connected to either of containers 4 and 18, and which folds into a "Z" when container 4 is housed entirely inside container 18, and unfolds when container 4 is extracted from container 18.
The position of the axis of rotation of hinge 27 is fixed with respect to containers 4 and 18 , by flexible strip 29 comprising an end portion 33 connected firmly to front wall 13 of container 4; and an opposite end portion 34 connected firmly to end wall 22 of container 18 and directly adjoining end portion 33.
Rear wall 20 of container 18 has a through hole 35 shaped and sized to permit insertion of a finger by the user. By way of example, the hole 35 shown in the accompanying drawings is circular with a diameter ranging between 20 mm and 30 mm.
As shown in Figures 7, 8 and 9, in actual use, to switch from the closed to the open configuration of packet 1, the user grips container 18, inserts a finger inside hole 35, and pushes rear wall 14 of container 4 to produce a relative movement between container 4 and container 18; which relative movement produces rotation of container 4 with respect to container 18 about hinge 27, and, at the same time, both rotation-translation of lid 7 with respect to container 18 about hinge 27, and rotation of lid 7 about hinge 8 to open container 4. To switch from the open to the closed configuration of
packet 1, the user simply pushes front wall 13 of container 4 to produce a relative movement between container 4 and container 18, which is substantially the same as, but in the opposite direction to, the opening movement described above.
Through hole 35 in rear wall 20, which serves to extract container 4 from container 18 , may be replaced with a strip (not shown) connected partly to front wall 13 of container 4 and which, in use, is gripped and pulled by the user.
In an alternative embodiment shown in Figures 10, 11 and 12, container 18 has no top end wall 21, and strip 28 of hinge 26 is connected firmly to lid 7 of container 4, at front wall 13, and to rear wall 20 of container 18. In other embodiments not shown, container 18 has no bottom end wall 22, or has neither of end walls 21, 22, or has neither of lateral walls 23. Normally, however, both end walls 21, 22 and lateral walls 23 are preferably provided, by imparting greater stability to container 18 and, therefore, greater strength to packet 1 as a whole. In the embodiment shown in the accompanying drawings, lateral walls 23 and end walls 21, 22 of container 18 are substantially the same size as minor lateral walls 12 and end walls 10, 11 of container 4, In an alternative embodiment not shown, lateral walls 23 and end walls 21, 22 of container 18 are smaller than minor lateral walls 12 and end walls 10, 11 of container 4, so that a strip, close to front wall 13, of
minor lateral walls 12 and end walls 10, 11 of container 4 is visible even when packet 1 is in the closed configuration.
In the embodiment shown in the accompanying drawings, edges 16 and 17 of container 4 and edges 24 and 25 of container 18 are square sharp edges.
In an alternative embodiment not shown, longitudinal edges 16 of container 4 are rounded or beveled, and longitudinal edges 24 of container 18 are also rounded or beveled to match the corresponding longitudinal edges 16 of container 4, which they are substantially positioned facing in use.
In a further embodiment not shown, at least some transverse edges 17 of container 4 are rounded or beveled, and the transverse edges 25 of container 18 • match the corresponding transverse edges 17 of container 4, which they are substantially positioned facing in use. In an alternative embodiment, container 4, and similarly container 18, is in the form of the packet of cigarettes described in Patent Application EP-A1-1066206, which- comprises an outwardly convex front and rear wall, each of which has a respective flat central portion, and two curved precreased lateral bands connecting the relative flat central portion to two flat lateral walls of the packet at respective sharp longitudinal edges .
Container 18 and/or container 4 may, of course, be made of other than paper material, e.g. plastic material. In view of the numerous advantages of packets 1 of
cigarettes described above, the form of packets 1 may also be used for producing other types of rigid containers for tobacco articles, such as cartons of packets of cigarettes, or cigar packets.
