This application claims the benefit of Italian Patent Application No. BO2010A 000157, filed Mar. 15, 2010.
The present invention relates to a rigid, hinged-lid package and relative packing method and machine.
In the following description, reference is made, for the sake of simplicity and purely by way of a non-limiting example, to a rigid, him-red-lid packet of cigarettes.
A rigid, hinged-lid packet of cigarettes normally comprises an inner package enclosing a group of cigarettes; and a rigid outer container housing the inner package and having the hinged lid.
To preserve the organoleptic characteristics of the tobacco, a sealed inner package has recently been proposed, which is formed by folding and heat-sealing a sheet of airtight packing material. To extract the cigarettes, the inner package has a cigarette extraction opening closed by a reclosable sealing panel (i.e. an open/close panel coated with non-dry, re-stick adhesive) fixed directly to the inner package. The sealing panel normally has a grip tab, with no re-stick adhesive, by which to grip and lift it easily. In other words, to lift the sealing panel, the user simply grips the grip tab, which, unlike the rest of the sealing panel, is in no way fixed to the inner package underneath.
Patent Application WO02079051A1 describes a rigid packet of cigarettes with a sealed inner package of the above type.
It is an object of the present invention to provide a rigid, hinged-lid package that is easier to use and, at the same time, cheap and easy to produce.
Another object of the present invention is to provide a packing method and machine by which to produce such a rigid, hinged-lid package.
According to the present invention, there are provided a rigid, hinged-lid package and relative packing method and machine, as claimed in the accompanying 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
Outer container 2 has an open top end 7; and a cup-shaped lid 8 hinged to container 2 along a hinge 9 (
When lid 8 is in the closed position, outer container 2 is in the Colin of a rectangular parallelepiped comprising a top wall 10 and bottom wall 11 opposite and parallel to each other; two opposite parallel major lateral walls 12, 13; and two opposite parallel minor lateral walls 14. More specifically, one major lateral wall 12 defines a front wall 12 of outer container 2, and the other major lateral wall 13 defines a rear wall 13 of outer container 2. Four longitudinal edges 15 are defined between lateral walls 14 and front and rear walls 12, 13; and eight transverse edges 16 are defined between top and bottom walls 10, 11 and front, rear, and lateral walls 12, 13, 14.
In the
Packet 1 also comprises a rigid (i.e. rigid-cardboard) collar 17, which is folded about inner package 3 to at least partly cover a top portion of inner package 3, and is fixed (normally glued) to inner package 3. In one embodiment, inner package 3 and/or collar 17 (which are glued integrally and non-detachably to each other) are/is also glued to outer container 2. Collar 17 (together with inner package 3 covered partly by it) projects partly outwards of open top end 7, and engages a corresponding inner surface of lid 8 when lid 8 is closed.
As shown more clearly in
Reclosable sealing panel 6 for closing extraction opening 5 of inner package 3 is located over collar 17, and has an inner surface 21 (
As shown in
In a preferred embodiment, reclosable sealing panel 6 incorporates a detachable portion 23 (
Reclosable sealing panel 6 is fixed permanently at the rear wall of inner package 3. Alternatively, collar 17 has no rear wall, and reclosable sealing panel 6 is fixed permanently directly to the rear wall of inner package 3; or collar 17 has a rear wall partly covering the rear wall of inner package 3, and reclosable sealing panel 6 is fixed permanently to the rear wall of collar 17.
Reclosable sealing panel 6 has a grip tab 25 with no re-stick adhesive on inner surface 21, and which is located close to, normally below, extraction opening 5 for easy grip and lift of sealing panel 6. In other words, sealing panel 6 can be raised by the user simply gripping grip tab 25, which, unlike the rest of sealing panel 6, is in no way fixed to collar 17 underneath.
As shown in
In a different embodiment, grip tab 25 is also initially positioned, i.e. from the outset, in the open configuration (
In the
In actual use, when grip tab 25 projects from lid 8 in the closed position, the user, to extract a cigarette from packet 1, can either push open lid 8 and then open sealing panel 6 by pulling up grip tab 25, or pull up grip tab 25 from the outset to open lid 8 and sealing panel 6 simultaneously. In other words, by pulling up grip tab 25 when lid 8 is in the closed position, lid 8 and sealing panel 6 can be opened simultaneously in one operation.
In an alternative embodiment, sealing panel 6 is glued to lid 8 (i.e. an outer surface of sealing panel 6 is glued to an inner surface of lid 8) so that sealing panel 6 and lid 8 open and close together.
The

Packing machine 27 comprises a known line 28 (only shown partly) for forming groups 4 of cigarettes; and a first transfer wheel 29, which rotates in steps about a respective horizontal axis of rotation 30 to successively receive groups 4 of cigarettes, and to transfer groups 4 of cigarettes to a second packing wheel 31 at a transfer station 32. Second packing wheel 31 is mounted to rotate in steps about a respective axis of rotation 33 parallel to axis of rotation 30, comprises a number of peripheral pockets 34, each for receiving a group 4 of cigarettes together with a respective flexible sheet 35 of foil packing material fed to transfer station 32 by a feed line 36, and folds each sheet 35 of packing material about respective group 4 of cigarettes to form an inner package 3.
Packing machine 27 also comprises a third packing wheel 37, which rotates in steps about a respective vertical axis of rotation 38 crosswise to axis of rotation 30. Third packing wheel 37 comprises a number of peripheral pockets 39, which are rotated in steps about axis of rotation 38 and fed successively through a feed station 40 for supplying creased cardboard blanks 41 complete with scaling panels 6 and from which to form collars 17. At feed station 40, each pocket 39 receives a blank 41, which is folded into a U inside pocket 39 by folding panels 23′ ninety deuces with respect to panel 19′ about the two longitudinal fold lines 35. Third packing wheel 37 also rotates through a transfer station 42 for transferring inner packages 3, and where an inner package 3 is inserted into the U-folded blank 41 inside each pocket 39. Downstream from transfer station 42, folding devices (not shown) finish folding each blank 41 about inner package 3 to form respective collar 17 complete with sealing panel 6. Finally, third packing wheel 37 rotates through a transfer station 43, where each inner package 3, fitted with a collar 17 complete with sealing panel 6, is expelled from pocket 39 and transferred to a fourth packing wheel 44.
Fourth packing wheel 44 rotates in steps about a respective axis of rotation 45 parallel to axis of rotation 38, is structurally identical to third packing wheel 37, and comprises a number of peripheral pockets 46. In pockets 39 on third packing wheel 37, and pockets 46 on fourth packing wheel 44, each rectangular-parallelepiped-shaped inner package 3 is positioned flat, i.e. with a minor lateral surface facing outwards, and with its longitudinal axis (the axis parallel to the cigarette axes) crosswise to axes of rotation 38, 45, and tangent to the periphery of packing wheels 37, 44. Fourth packing wheel 44 and third packing wheel 37 overlap at transfer station 43, and inner packages 3 are transferred from third packing wheel 37 to fourth packing wheel 44 in a vertical movement parallel to axes of rotation 38, 45.
At a transfer station 47, each inner package 3, fitted with a collar 17 complete with sealing panel 6, is transferred from a pocket 46 on fourth packing wheel 44 to a pocket 48 on a fifth packing wheel 49. Fifth packing wheel 49 is mounted to rotate in steps about a respective horizontal axis of rotation 50 parallel to axis of rotation 30, receives each inner package 3 and respective collar 17, complete with sealing panel 6, together with a respective rigid blank 51 fed to transfer station 47 by a feed line 52, and folds each blank 51 about relative inner package 3 to form a packet 1 of cigarettes, in which inner package 3 is housed inside an outer container 2 formed by folding blank 51.
Packets 1 are transferred successively from fifth packing wheel 49 to a sixth transfer wheel 53 at a transfer station 54. More specifically, each packet 1 arriving at transfer station 54 is positioned on edge on the periphery of fifth packing wheel 49, i.e. with a major lateral surface of packet 1 facing outwards, and with the longitudinal axis (the axis parallel to the cigarettes) of packet 1 parallel to axis of rotation 50 of fifth packing wheel 49.
Sixth transfer wheel 53 rotates in steps about a respective vertical axis of rotation 55 crosswise to axis of rotation 50 of fifth packing wheel 49, receives packets 1 successively from fifth packing wheel 49 at transfer station 54, and transfers packets 1 to a drying area 56 (shown schematically) at a transfer station 57. Drying area 56 forms the output of packing machine 27, and feeds packets 1 of cigarettes to a follow-up cellophaning machine (not shown which applies an overwrap of transparent plastic material about each packet 1 of cigarettes.
Feed line 36 supplying flexible sheets 35 of foil packing material has a cutting device 58, which makes U-shaped incision 22, defining cigarette extraction opening 5, in each sheet 35.
Blanks 41 from which collars 17 are made are fed to feed station 40 on a feed line 59, and are obtained in known manner by transversely cutting a continuous strip of cardboard unwound off a reel 60. Feed line 59 comprises a cutting device 61 for forming in each blank 41 U-shaped incision 24 defining detachable portion 23 of collar 17, which adheres to reclosable sealing panel 6; and an application device 62 for applying reclosable sealing panel 6 to each blank 41. Reclosable sealing panel 6 is preferably obtained from a reel, with non-dry, re-stick adhesive already applied to inner surface 21 (i.e. is self-adhesive).
A gumming device 63 applies adhesive (non-dry, re-stick or permanent adhesive) to the side of detachable portion 23 of each collar 17 facing inner package 3, so that detachable portion 23 adheres to the part of inner package 3 bounded by incision 22. In
As shown in
In a preferred embodiment shown in
Packet 1 of cigarettes described above has numerous advantages.
In particular, it allows lid 8 and sealing panel 6 to be opened simultaneously in one operation by simply pulling up grip tab 25 projecting from lid 8 in the closed position closing open top end 7 of outer container 2, thus making packet 1 of cigarettes much easier to use as compared with similar known packets of cigarettes.
Secondly, packet 1 of cigarettes described indicates clearly whether lid 8 is sealed (in which case, grip tab 25 does not project from lid 8 in the closed position closing open top end 7 of outer container 2) or has been opened (in which case, grip tab 25 projects from lid 8 in the closed position closing open top end 7 of outer container 2).
Finally, packet 1 of cigarettes described can easily be produced on a standard packing machine (which only requires a few minor alterations), as opposed to a special, high-cost packing machine (i.e. specially designed for packets of cigarettes of this type).
In view of its many advantages, the package described may also be used for articles other than cigarettes, e.g. food products (such as sweets, chocolates or other confectionary).
