This application claims the benefit of Italian Patent Application No. BO2010A 000670, filed Nov. 9, 2010.
The present invention relates to a hinged-lid package.
In the following description, reference is made, for the sake of simplicity and purely by way of a non-limiting example, to a hinged-lid packet of cigarettes, preferably containing a lighter and a group of cigarettes.
Various types of rigid packets of cigarettes containing a rigid object, normally a lighter, have been proposed, as described, for example, in Patents DE102004013741A1, U.S. Pat. No. 5,908,734A1, U.S. Pat. No. 4,621,649A1, DE3530808A1, U.S. Pat. No. 3,069,886A1 and U.S. Pat. No. 5,908,734.
Known rigid packets of cigarettes containing a lighter, however, are extremely complicated to produce on a standard packing machine, and so either require a specially designed, much more expensive machine (normally with a low output rate), or fail to adequately protect the lighter.
Patent Application EP1792832A1 describes a hinged-lid package formed by folding one blank and comprising:
a parallelepiped-shaped, cup-shaped container comprising a bottom wall; an open top end opposite the bottom wall; a front wall and an opposite, parallel rear wall; and two parallel lateral walls interposed between the front and rear walls;
a lid, which rotates between a closed position and an open position closing and opening the top end of the container respectively, and which comprises a top wall hinged to the rear wall of the container; and a front wall which, in the closed position, is superimposed on the front wall of the container; and
a border, which is parallel to the bottom wall, surrounds the open top end on all four sides, thus reducing the size of the open top end, and on which the top wall of the lid rests in the closed position.
It is an object of the present invention to provide a hinged-lid package that is cheap and easy to produce.
According to the present invention, there is provided a hinged-lid package, 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
The
In the embodiment shown, the longitudinal and transverse edges defined between walls 4, 6-9, 11 and 12 of container 2 and lid 10 are square, but, in an alternative embodiment not shown, at least some longitudinal and/or transverse edges are rounded or bevelled.
In a preferred embodiment, lid 10 is initially connected to container 2 along a tear line 13, which is torn, when unsealing lid 10, to separate lid 10 permanently from container 2. Tear line 13 serves to hold lid 10 firmly in the closed position until it is unsealed, and also acts as a ‘guarantee seal’ ensuring packet 1 of cigarettes has not been tampered with. In the
In a preferred embodiment, a border 14, parallel to bottom wall 4, surrounds open top end 5 on at least three sides, reduces the size of open top end 5, and supports top wall 11 of lid 10 in the closed position. In the
Border 14 preferably (though not necessarily) comprises a cover 15, which initially closes the whole of open top end 5 within border 14, is initially connected to the edges of border 14 along a tear line 16, and is glued to the inner surface of top wall 11 of lid 10 so as to be torn off border 14 along tear line 16 when lid 10 is unsealed. In other words, when packet 1 of cigarettes is sealed, cover 15 is connected on all four sides to border 14, and, when lid 10 is unsealed, is torn off border 14 on all four sides along tear line 16. Tear line 16 preferably extends seamlessly about all four sides of cover 15, but may alternatively be U-shaped, i.e. interrupted at rear wall 7 of container 2 (in which case, cover 15 is separated completely from border 14 at rear wall 7 of container 2 from the outset).
In a preferred embodiment, cover 15 has a central through hole 17, which plays an important part in the manufacture of packet 1 of cigarettes, as explained below. In one embodiment, the inner surface of top wall 11 of lid 10 has printing 18 located at and visible through hole 17 in cover 15.
The content 3 of packet 1 of cigarettes comprises a rigid, parallelepiped-shaped object 19 (normally, though not necessarily, a lighter); and a parallelepiped-shaped article 20 defined by a wrapped group of cigarettes, i.e. wrapped in a sheet of foil wrap. In
In a preferred embodiment, packet 1 of cigarettes comprises an insert 21, which comprises border 14, is initially separate from container 2, and is glued to the inside of container 2. As shown in
Insert 21 comprises two supports 26 connected to lateral walls 24, 25, and projecting inwards of container 2 to support object 19. Each support 26 comprises a tab 27 connected to the bottom edge of lateral wall 24, 25 of insert 21, and which is folded onto and glued to lateral wall 24, 25 of insert 21; and a tab 28 connected to tab 27 and projecting inwards of container 2 to support object 19 (i.e. part of content 3 of container 2). Each tab 28 comprises a central through recess 29 engaged by rigid object 19 and defined by a U-shaped through cut 30; and a fold line 31, which forms an intermediate fold in tab 28, and is located at the tips of U-shaped through cut 30.
In a preferred embodiment, packet 1 of cigarettes comprises a retaining system for holding lid 10 in the closed position after it is unsealed (before it is unsealed, lid 10 is held firmly in the closed position by tear line 13, which is torn to unseal lid 10). In the embodiment shown, the lid retaining system comprises (by way of example) two spots 32 of glue applied to front wall 6 of container 2, and to which the inner surface of front wall 12 of lid 10 adheres when lid 10 is in the closed position. Spots 32 are made of non-dry, weak-stick glue, which remains adhesive even after frequent use, thus enabling lid 10 to be opened and closed repeatedly.
Container 2 and lid 10 are formed by folding a single blank 33 as shown in
As shown in
Blank 33 comprises a panel 7′ connected to panel 4′ along one longitudinal fold line 34, and which forms an inner portion of rear wall 7 of container 2; and a panel 6′ connected to panel 4′ along the other longitudinal fold line 34, and which forms front wall 6 of container 2. Panel 6′ and panel 7′ each have two tabs 36, which are connected to panel 6′, 7′ along transverse fold lines 35, are folded 90° with respect to panel 6′, 7′, and are glued to the inner surfaces of panel 9′ and panel 8′ respectively.
Blank 33 comprises a panel 7″ connected to panel 11′ along one longitudinal fold line 34, and which forms an outer portion of rear wall 7 of container 2; and a panel 12′ connected to panel 11′ along the other longitudinal fold line 34, and which forms front wall 12 of lid 10. Panel 12′ comprises two detachable portions 37, which are glued to panel 6′ forming front wall 6 of container 2 (and so form an integral part of front wall 6 of container 2), and are connected along tear line 13 to the rest of panel 12′ forming front wall 12 of lid 10. The two detachable portions 37 are separated completely by a user grip tab 38, by which to pull up lid 10 to open packet 1 of cigarettes.
On either side of panel 11′, tear line 13 coincides with corresponding transverse fold lines 35.
Insert 21 is formed by folding a blank 39, as shown in
As shown in
Blank 33 in
From the fully spread-out configuration in
In a preferred embodiment, two parallel adjacent longitudinal fold lines 34 (obviously only a small distance apart) are provided between panels 11′ and 12′ to make blank 33 more flexible in this area, and so prevent panel 11′ (i.e. top wall 11 of lid 10) from arching as a result of the stress produced in blank 33 once it is folded. In other words, the two longitudinal fold lines 34 between panels 11′ and 12′ serve to keep top wall 11 of lid 10 perfectly flat, and so improve the look of packet 1 of cigarettes when open.
In a preferred embodiment, blank 33 comprises an appendix 43 connected to panel 9′ along a transverse fold line 35, and which is glued to a bottom surface of panel 14; and an appendix 44 connected to panel 6′ along a longitudinal fold line 34, and which is also glued to a bottom surface of panel 14′.
In the
Blank 33 in
Cigarette packing machine 46 comprises a group forming line (not shown) for forming groups of cigarettes; and a transfer wheel 47, which rotates in steps about a horizontal axis of rotation 48 to receive and transfer the groups of cigarettes successively to a packing wheel 49 at a transfer station 50. Packing wheel 49 rotates in steps about an axis of rotation 51 parallel to axis of rotation 48, and comprises a number of peripheral pockets 52, each for receiving a group of cigarettes together with a respective sheet of flexible foil packing material (not shown). And packing wheel 49 folds each sheet of packing material about the respective group of cigarettes to form a wrapped group of cigarettes defining article 20 of content 3 of packet 1 of cigarettes.
Packing machine 46 also comprises a transfer wheel 53, which rotates in steps about a vertical axis of rotation 54 crosswise to axis of rotation 48, and comprises a number of peripheral pockets 55, which are fed in steps about axis of rotation 54 to travel successively through a coupon feed station 56 where each pocket 55 receives a coupon 57 (shown in
Packing wheel 60 rotates in steps about an axis of rotation 61 parallel to axis of rotation 54, is identical in design to transfer wheel 53, and comprises a number of peripheral pockets 62. In both pockets 55 on transfer wheel 53, and pockets 62 on packing wheel 60, each rectangular-parallelepiped-shaped article 20 is positioned flat, i.e. with a minor lateral surface facing outwards, and with its longitudinal axis (parallel to the cigarette axes) crosswise to axes of rotation 54 and 61, and tangent to the periphery of transfer wheel 53 and packing wheel 60. Packing wheel 60 and transfer wheel 53 overlap at transfer station 59, and articles 20 are transferred from transfer wheel 53 to packing wheel 60 vertically in a direction parallel to axes of rotation 54 and 61. More specifically, transfer wheel 53 overlaps packing wheel 60, and each article 20 is transferred downwards, out through a bottom opening in pocket 55 on transfer wheel 53, and in through a top opening in pocket 62 on packing wheel 60 (obviously, pocket 55 is aligned vertically with pocket 62).
At a feed station 63 upstream from transfer station 59, a feed device 64 inserts a blank 39 into a pocket 62 on packing wheel 60 to form an insert 21; and, at a feed station 65 between feed station 63 and transfer station 59 (i.e. upstream from transfer station 59), a feed device 66 inserts an object 19 into a pocket 62 on packing wheel 60 and onto the previously supplied insert 21. At transfer station 59, an article 20 is inserted into a pocket 62 on packing wheel 60 and onto the previously supplied insert 21 and object 20, thus completing formation of content 3 of packet 1 of cigarettes. It is important to note that, at feed station 63, blank 39 is inserted into a pocket 62 on packing wheel 60 already partly folded as shown in
At a transfer station 67, each content 3, together with insert 21, is transferred from a pocket 62 on packing wheel 60 to a pocket 68 on a packing wheel 69, which rotates in steps about a horizontal axis of rotation 70 parallel to axis of rotation 48, receives each content 3 and respective insert 21 together with a respective rigid blank 33 fed to transfer station 67 by a feed device 71, and folds each blank about respective content 3 and insert 21 to form a packet 1 of cigarettes. It is important to note that, when using blank 33 in
At a transfer station 72, packets 1 of cigarettes are fed successively from packing wheel 69 to a further transfer wheel (not shown), from which they are fed to a drying area (not shown) forming the output of packing machine 46, and which feeds packets 1 of cigarettes to a follow-up cellophaning machine (not shown), which wraps each in a transparent plastic overwrap.
At feed station 63, feed device 64 feeds a blank 39, from which to form an insert 21, into a pocket 62 on packing wheel 60. As it is inserted into pocket 62, blank 39 folds inwards of pocket 62 to form a cup-shaped insert 21 with its inlet opening facing upwards (i.e. facing transfer wheel 53, from which article 20 is inserted into insert 21 at transfer station 59); and feed device 66 at feed station 65 then inserts an object 19 into pocket 62, and therefore into insert 21.
As shown in
At transfer station 59, a pocket 55 on transfer wheel 53 is aligned vertically with a pocket 62 on packing wheel 60 underneath; and an article 20 is transferred from pocket 55 on transfer wheel 53 to pocket 62 on packing wheel 60 by a feed device 75 comprising a pusher 76 over transfer station 59, and a counterpusher 77 below transfer station 59. As shown in
Counterpusher 77 is fork-shaped, i.e. U-shaped (with two parallel, spaced arms), to avoid interfering with object 19, which is located between the two arms of the fork, as counterpusher 77 moves up through pocket 62 on packing wheel 60 to engage article 20. It is important to note that, to move through pocket 62 on packing wheel 60, counterpusher 77 must also move through border 14 of insert 21 located inside pocket 62. This is made possible by through hole 17 in border 14, through which counterpusher 77 moves, and which is essential to enable counterpusher 77 to move up through pocket 62 on packing wheel 60, to engage article 20. Obviously, pocket 62 on packing wheel 60 must also have a through hole aligned with through hole 17 in border 14, and through which to move counterpusher 77.
At transfer station 67, content 3 (i.e. object 19 and article 20) enclosed in insert 21 is transferred from a pocket 62 on packing wheel 60 to a pocket 68 on packing wheel 69, together with a blank 33. At this stage, blank 33 is inserted into pocket 68 folded into a U about content 3 in insert 21, and, inside pocket 68 on packing wheel 69, is folded about content 3 in insert 21 to form container 2 with lid 10, and so complete packet 1 of cigarettes.
When content 3 of packet 1 of cigarettes only comprises one or more articles 20 (i.e. one or more wrapped groups of cigarettes), only minor alterations to packing machine 46 are required: feed device 66 supplying objects 19 must obviously be disabled; the type of blank 39 supplied at feed station 63 must be changed (i.e. the
Obviously, content 3 of packet 1 of cigarettes may differ from that described by way of example: as opposed to a lighter, object 19 may be any rigid object (such as a cigarette-holder); and, instead of a wrapped group of cigarettes, article 20 may be any other type of article (such as a group of cigarette-holder filters).
Packet 1 of cigarettes described has numerous advantages, by being able to house a rigid object 19, while at the same time being produced on a substantially standard packing machine 46 (i.e. identical to a standard packing machine, except for a few minor alterations to adapt to the new format). In particular, rigid object 19 is accommodated firmly inside packet 1 of cigarettes, and can be repeatedly removed and replaced easily.
Given its numerous advantages, the design of packet 1 of cigarettes described may also be used for producing cartons of cigarettes, which are substantially identical to packet 1 of cigarettes described, the only difference being that content 3 is defined by a group of packets of cigarettes.
Packing machine 46 described also has numerous advantages, by being identical to a standard packing machine, and by effectively producing packet 1 of cigarettes described.
