This application claims the benefit of European patent application No. 08153811.8, filed Mar. 31, 2008 and Italian patent application No. BO 2007A000480, filed Jul. 17, 2007.
The present invention relates to a rigid swing-open packet of cigarettes.
Rigid, hinged-lid packets of cigarettes are currently the most widely marketed, by being easy to produce, practical and easy to use, and by effectively protecting the cigarettes inside.
In addition to rigid, hinged-lid packets of cigarettes, rigid slide-open or swing-open packets of cigarettes have been proposed comprising two containers, one inserted in partly removable manner inside the other. In other words, a rigid slide-open or swing-open packet of cigarettes comprises a first container housing a group of cigarettes, and in turn housed inside a second container to move, with respect to the second container, between a closed position, in which the first container is inserted inside the second container, and an open position, in which the first container is extracted from the second container. The movement of the first container with respect to the second container may be either a straight (slide-open) movement, or a rotational (swing-open) movement about a hinge connecting the two containers.
A number of embodiments of rigid, straight slide-open packets of cigarettes are described in FR2499947A1, U.S. Pat. Nos. 4,534,463A1 and 5,080,227A1, and one embodiment of a rigid, swing-open packet of cigarettes is described in WO2006021581.
Known rigid swing-open packets of cigarettes, however, have various drawbacks, by being complicated and expensive to produce, and relatively complicated to open.
It is an object of the present invention to provide a rigid swing-open packet of cigarettes 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 swing-open packet of cigarettes as claimed in the attached Claims.
A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which:
Number 1 in
The
Each inner container 3 is hinged to outer container 4 at a hinge 14 to rotate, with respect to outer container 4, between a closed position (
Each inner container 3 is parallelepiped- and cup-shaped, and has an open top end 5 from which the cigarettes are withdrawn; a bottom wall 6 opposite open top end 5; a front wall 7; a rear wall 8 opposite and parallel to front wall 7; and two opposite parallel lateral walls 9.
Outer container 4 is also parallelepiped-shaped, and has a top wall 10; a bottom wall 11 opposite and parallel to top wall 10; two opposite parallel lateral walls 12; and two opposite open lateral ends 13, through each of which an inner container 3 is extracted from or inserted into outer container 4 into the open or closed position respectively.
Each inner container 3 is hinged to outer container 4 by a hinge 14 located between an edge of bottom wall 6 of inner container 3 and an edge of bottom wall 11 of outer container 4 at a respective open lateral end 13 of outer container 4.
In a preferred embodiment, rear wall 8 of each container 3 is lower than front wall 7, so that, in the closed position, front wall 7 closes respective open lateral end 13 of outer container 4 completely, and rotation of inner container 3 about hinge 14 and with respect to outer container 4 is not impeded by rear wall 8 interfering with top wall 10 of outer container 4; and the top portion of each lateral wall 9 of each inner container 3 is shaped to connect front wall 7 smoothly to rear wall 8 to compensate for the difference in height.
Packet 1 of cigarettes has stop means for limiting extraction, and preventing excessive extraction, of each inner container 3 from outer container 4, and which, for each inner container 3, comprise two retaining tabs 15 projecting outwards of outer container 4 from lateral walls 9 of inner container 3 and located close to rear wall 8 of inner container 3; and two retaining pockets 16 projecting inwards of outer container 4 from lateral walls 12 of outer container 4 and located close to the relative open end 13 of outer container 4. In actual use, as inner container 3 rotates, about hinge 14 and with respect to outer container 4, from the closed to the open position, each retaining tab 15 engages a respective retaining pocket 16 to arrest extraction of inner container 3.
To open each inner container 3, the user of packet 1 of cigarettes must pull inner container 3 with respect to outer container 4, and must therefore grip outer container 4 with one hand, and inner container 3 with the other. For easy grip of inner containers 3, each inner container 3 may comprise a grip tab (not shown) projecting outwards from a top edge of front wall 7; or each lateral wall 12 of outer container 4 may have a recess (e.g. semicircular) close to each open lateral end 13, so the user of packet 1 of cigarettes can grip and exert pull on lateral walls 9 of each inner container 3; or top wall 10 of outer container 4 may have a recess (e.g. semicircular) close to each open lateral end 13, so the user of packet 1 of cigarettes can grip and exert pull on front wall 7 of each inner container 3; or front wall 7 of each inner container 3 may have a recess (e.g. semicircular) at the top.

As shown in
Blank 17 has two longitudinal fold lines 18, and a number of transverse fold lines 19 defining, between the two longitudinal fold lines 18, a panel 8′ forming rear wall 8; a panel 6′ forming bottom wall 6; and a panel 7′ forming front wall 7.
Panel 7′ has a reinforcing flap 20 connected to panel 7′ along a transverse fold line 19, and which is folded 180° onto panel 7′ to strengthen the top portion of front wall 7.
Panel 8′ has two lateral wings 9′, which form respective inner portions of lateral walls 9, are located on opposite sides of panel 8′, and are separated from panel 8′ by longitudinal fold lines 18. Panel 7′ has two lateral wings 9″, which form respective outer portions of lateral walls 9, are located on opposite sides of panel 7′, and are separated from panel 7′ by longitudinal fold lines 18. Each lateral wing 9′ of panel 8′ has a tab 21 separated from lateral wing 9′ by a transverse fold line 19. A window 22 is formed in each lateral wing 9′ and contains a respective retaining tab 15. And each lateral wing 9″ has a recess 23 located so as to be superimposed over a respective retaining tab 15.
To form inner container 3, panels 7′ and 8′ are folded 90° with respect to panel 6′; lateral wings 9′ are folded 90° with respect to panel 8′; and lateral wings 9″ are folded 90° with respect to panel 7′ and on top of the folded lateral wings 9′.
As shown in
Blank 24 has two longitudinal fold lines 25, and a number of transverse fold lines 26 defining, between the two longitudinal fold lines 25, a panel 11′ forming an inner portion of bottom wall 11; a panel 12′ forming one lateral wall 12; a panel 10′ forming top wall 10; a panel 12″ forming the other lateral wall 12; and a panel 11″ forming an outer portion of bottom wall 11.
Panel 10′ has two reinforcing flaps 27, which are located on opposite sides of panel 10′, are separated from panel 10′ by longitudinal fold lines 25, and are folded 180° onto panel 10′ to strengthen top wall 10.
Panels 12′, 12″ each have two retaining pockets 16, which are located on opposite sides of panel 12′, 12″, are separated from panel 12′, 12″ by longitudinal fold lines 25, and are folded 180° onto panel 12′, 12″.
Panel 11′ has two connecting tabs 28, which are located on opposite sides of panel 11′, are separated from panel 11′ by longitudinal fold lines 25, and are folded 180° onto panel 11′. Each connecting tab 28 is glued to bottom wall 6 of a respective inner container 3 to hinge the inner container 3 to outer container 4, so the portion of longitudinal fold line 25 separating each connecting tab 28 from panel 11′ forms the hinge 14 of a respective inner container 3.
To form outer container 4, retaining pockets 16 are folded 180° onto relative panels 12′, 12″; reinforcing flaps 27 are folded 180° onto panel 10′; connecting tabs 28 are folded 180° onto panel 11′; panels 12′, 12″ are folded 90° with respect to panel 10′; panel 11′ is folded 90° with respect to panel 12′; and panel 11″ is folded 90° with respect to panel 12″ and on top of the folded panel 11′.

Each lid 29 comprises a rectangular top wall 31 opposite and parallel to bottom wall 6 of inner container 3 when lid 29 is in the closed position; a rectangular rear wall 32 which forms an extension of rear wall 8 of inner container 3 when lid 29 is in the closed position; and two triangular lateral walls 33 which form extensions of lateral walls 9 of inner container 3 when lid 29 is in the closed position. And hinge 30 of each lid 29 connects a top edge of rear wall 8 of inner container 3 to a bottom edge of rear wall 32 of lid 29.
In a preferred embodiment, each lid 29 has an actuating system 34 which connects lid 29 to outer container 4 so that, when inner container 3 is extracted from/inserted into outer container 4, lid 29 is connected to outer container 4 to open/close lid 29. By means of actuating system 34, each lid 29 is therefore opened/closed “automatically”, with no manual effort on the part of the user, by extracting/inserting inner container 3. As shown in
As described above, each inner container 3 is hinged to outer container 4 by a connecting tab 28, which is hinged to outer container 4 along hinge 14 and glued to bottom wall 6 of inner container 3. Each connecting tab 28 is not normally glued to bottom wall 11 of outer container 4, so as to rotate freely with respect to outer container 4. Alternatively, each connecting tab 28 may be glued to bottom wall 11 of outer container 4 using non-setting, re-stick adhesive applied between the bottom surface of connecting tab 28 and the top surface of bottom wall 11 of outer container 4, so connecting tab 28 can be detached repeatedly from bottom wall 11 (i.e. each time inner container 3 is extracted from packet 1 of cigarettes) and then fixed back to bottom wall 11. In one variation, each connecting tab 28 is glued to bottom wall 11 of outer container 4 using weak-stick adhesive which releases its hold the first time inner container 3 is extracted. In another variation, connecting tab 28 is fixed to bottom wall 11 of outer container 4 by a tear line which is torn the first time inner container 3 is extracted. In a different embodiment, as opposed to being hinged to outer container 4 and glued to inner container 3, each connecting tab 28 may be hinged to inner container 3 and glued to outer container 4.

Locating the two hinges 14 closer to each other improves extraction of inner containers 3, and reduces the distance between top wall 31 of each lid 29 and top wall 10 of outer container 4 when inner containers 3 are in the closed position. The

In a different embodiment not shown, packet 1 of cigarettes comprises a retaining member for holding a respective inner container 3 in the closed position with a certain amount of force, and which, for each inner container 3, comprises a deformable member that must be deformed to move the inner container 3 from the closed to the open position. In other words, to move an inner container 3 from the closed to the open position, sufficient force must be exerted on inner container 3 to deform the deformable member elastically. The function of the retaining member is to hold the inner container 3 in the closed position with a certain amount of force, and so prevent inner container 3 from opening accidentally.
The
Each cut 41 provides for a more supple connection of tab 37 and wing 33′, so that less force is required to rotate tab 37 with respect to wing 33′. To be inserted inside slot 36, each actuating tab 35 must deform tabs 37, the force required to do which is reduced by cuts 41, thus making it easier to insert actuating tab 35 inside slot 36. It is important to note that tabs 37, on the one hand, oppose insertion of actuating tab 35 inside slot 36, but, on the other, assist in holding actuating tab 35, once inserted, inside slot 36. Cuts 41 provide for achieving just the right elasticity of tabs 37, and which represents the best compromise between allowing insertion of actuating tab 35 inside slot 36, and holding actuating tab 35, once inserted, inside slot 36.
In the embodiments shown in the attached drawings, the longitudinal and transverse edges of inner container 3 and outer container 4 are all square. Alternatively, the longitudinal and/or transverse edges of inner container 3 and outer container 4 may be non-square rounded or bevelled edges. Blanks 24 for forming outer container 4 with rounded or bevelled longitudinal edges are shown in
Packet 1 of cigarettes as described herein has numerous advantages, by being easy to produce, and, above all, by making inner containers 3 extremely easy to open (i.e. extract from outer container 4).
