Abstract
A wrapping for an object includes an opening line made up of a tear tape by which the user opens the wrapping in order to gain access to its contents. A coupon bearing markings for publicity or other reasons is attached to a face of the wrapped object. The coupon also includes an opening line allowing access to information contained on inner pages of a coupon. The opening line of the wrapping and the opening line of the coupon are juxtaposed so that the user simultaneously opens the coupon and the wrapping.
Description
FIELD OF THE INVENTION
The present invention relates to a wrapping provided with a publicity or other coupon on at least one of its outside faces, as well as to a process permitting such a wrapping to be made.
BACKGROUND OF THE INVENTION
Wrappings, especially but not exclusively cigarette packs, are found provided on one face with a coupon which can be opened in order to be read, said coupon bearing publicity indications, directions for use, indications for a contest, or any other appropriate indications.
U.S. Pat. No. 5,035,935 describes a pack of cigarettes provided with such a coupon disposed under the transparent film covering the pack of cigarettes. Such an arrangement necessitates removing the transparent film completely before being able to get to the coupon. On the other hand, in view of the necessity of the transparent film, this arrangement cannot be adapted to a wrapping made up of a single layer, i.e., without the outside transparent film. Another drawback of the means proposed is that it is not possible to open the pack of cigarettes and the coupon simultaneously.
EP Application No. EP-A-0 803 450 also describes a pack of cigarettes provided with a tax coupon under the outside transparent film. Seeing that the coupon is attached to the surface of the web of film which will be situated against the pack of cigarettes, it is necessary to provide for an additional step at the time of production of the film in order to dispose the tear tape simultaneously permitting opening of the transparent film and tearing of the tax coupon. Note that in this case, the tax coupon is not intended to be read after opening of the pack.
SUMMARY OF THE INVENTION
A first object of the invention is therefore to propose a wrapping of one or of a plurality of packs or of objects, provided on at least one of its outside faces with a closed coupon, the means for opening the wrapping and the coupon being coordinated in such a way that opening of the wrapping causes simultaneous opening of the coupon.
A second object of the invention is to permit such an arrangement to be adapted to all sorts of wrappings, especially but not exclusively to wrappings of packs of cigarettes, of the stiff or soft type including an outside wrapping film or of the soft type made up of a single thickness, i.e., without the outer film.
A third object of the invention is to permit such an arrangement to be adapted to all sorts of coupons, e.g., coupons partially or totally covering one or two faces of the wrapping, coupons of various shapes and sizes, coupons which can contain an inner insert unfoldable in any way, coupons which can contain a detachable insert, etc.
Another object of the invention is to propose at least one process for producing such a wrapping.

FIGS. 7A and 7B
are cross-sections of another embodiment of a coupon, in closed state and in open state, respectively,
FIG. 8
describes diagrammatically a first process permitting a wrapping provided with a coupon to be obtained, and
FIG. 9
describes diagrammatically another process permitting a wrapping provided with a coupon to be obtained.
DETAILED DESCRIPTION OF THE INVENTION
Although the figures and the following description relate to a pack of cigarettes, the concepts of pack and of wrapping must be extended to any type of wrapping of any product on which a coupon can be disposed according to one or the other of the ways described. The shape of the wrapping need also not be that of a parallelepiped as shown, but may be of a different shape, e.g., circular cylindrical.
In
FIG. 1
there is a pack of cigarettes
1
, e.g., of the stiff type, covered with a film
2
of a preferably transparent material such as cellophane, polypropylene, or any other material customarily used for this purpose. Here the pack
1
is provided with a coupon
3
disposed on one of its faces, outside the film
2
. The outside face
30
of the coupon
3
is visible and may bear a logo, a publicity indication, or any other indication. At the time of the sale of the pack
1
, the coupon
3
must be closed; it must be possible to open it to read the information it contains or to get to its contents only at the time of or after opening of the pack
1
. The way in which the coupon
3
is closed is described in detail below with reference to the explanations concerning FIG.
6
A.
For opening the pack
1
, the film
2
is conventionally provided here with a tear tape
20
, integrated in the film
2
and going around the side faces of the pack
1
, one end of the tear tape
20
being provided with a tear tongue
21
, shown here unfolded for being grasped. The coupon
3
is provided with a line
31
, the mechanical resistance of which is weakened, e.g., by successive perforations, this line of weakened resistance
31
being disposed essentially parallel to and facing a portion of the tear tape
20
. The line of weakened resistance separates the coupon
3
into two portions, a first portion
300
, the larger one, which is attached to the portion
22
of the film
2
which will remain on the pack
1
after its opening, and a second portion
301
which is attached to the portion
23
of the film
2
which will be removed at the time of opening of the pack
1
, then disposed of. Thus, in view of the congruence of the line
31
on the tear tape
20
, at the time of opening of the pack
1
by pulling on the tear tape
20
to remove the upper portion
23
of the film
2
, the coupon
3
is opened simultaneously, permitting the user to get to the information it contains.
FIG. 2
shows the same pack when the tear tape
20
and the upper portion
23
of the film
2
have been removed, leaving the lower portion
22
of the film
2
on the pack
1
, to which portion the coupon
3
is attached. The upper portion
10
of the pack
1
may now be opened conventionally to get to the cigarettes or other objects it contains. Simultaneously, the faces or inside pages
302
and
303
of the coupon
3
which could not be reached previously when the wrapping was closed are now accessible by unfolding the coupon
3
about a fold
32
.
FIG. 3
shows another embodiment of a pack of cigarettes
1
, the wrapping
4
of which is obtained from a single sheet of a single layer, as described in EP Patent No. EP-B-0 633 201, for example. Such a wrapping relating to a soft-type pack of cigarettes does not include the film
2
of the previous wrapping. Such a wrapping may be provided with a tear tape
40
and with a tear tongue
41
. The coupon
3
is shown here in essentially circular shape but might also be of a different shape, including a fold
32
for opening as mentioned previously, as well as a line of weakened resistance
31
.
In the above embodiments, it is noted that the top face of the pack
1
includes the folded closures of the film
2
for the embodiment of
FIG. 1
, or of the wrapping blank
4
for the embodiment of FIG.
3
. Such an arrangement of a face prevents disposing the tear tape there in view of the superimposition of the folded layers. Nevertheless, if it is desired to dispose a coupon
3
on a face of the pack
1
comprising folds of the film or of the wrapping sheet as, for example, the top face or the bottom face, it is possible to fit out the pack
1
as shown in
FIG. 4
, i.e., by providing that the tear tape
20
is disposed close to the edge of the top face and attaching the main portion
300
of the coupon
3
essentially to the top face, while the portion
301
is folded down on a side face so that the line of weakened resistance
31
is superimposed on a portion of the tear tape
20
.
FIG. 5
shows still another embodiment of a coupon
3
which here opens into two sections. The coupon
3
shown here essentially covers a whole face of the pack
1
. The tear tape
20
is no longer disposed close to an edge of the coupon
3
but in a more central position, so that the coupon opens into two opposing sections. In the example shown in the figure, the tear tape
20
has been removed, which has torn the line of pre-weakened resistance
31
of the coupon
3
and permitted the two sections to be opened. It is not necessary for the two portions
300
and
301
of the coupon
3
to be of equal size; one or the other of the two said portions may be larger than the other. Similarly, it is not obligatory for the coupon
3
to be disposed so that the opening line
31
is parallel to the folding line
32
; by disposing these two lines at a certain angle to one another, the two sections may be given different shapes. The portion
301
attached to the portion
23
of the wrapping to be disposed of may, for example, adhere there so that it can easily be partially or totally detached therefrom, or else contain a detachable self-adhesive insert
35
. According to a modification of this embodiment, the portion
300
of the coupon is disposed on a frontal or lateral face of the pack, while the portion
301
is disposed on a top face of the pack, as shown in FIG.
4
. Such a modification is particularly well adapted to a soft-type, single-layer pack, as described above.
FIGS. 6A and 6B
, as well as
7
A and
7
B, show, in section, two possible embodiments of a coupon
3
.
In
FIG. 6A
, the coupon
3
is formed of a leaf, folded about a folding line forming a fold
32
, the portion
320
of the coupon
3
opposite the fold
32
being closed, e.g., by a closure means, e.g., a spot or a line of glue
321
, or by crimping, so as to keep the coupon closed before opening of the wrapping. It is also possible, instead of a folded leaf, to have two leaves assembled along the line
32
, as well as on the opposite portion
320
. The line
31
of pre-weakened resistance, e.g., a pre-cut line laid out on the two superimposed portions of the leaf, is here disposed close to this closure line
321
, the line of weakened resistance
31
separating the coupon
3
into a main portion
300
and another portion
301
. The face of this assembly, opposite the face
30
which is visible on the outside of the pack
1
, is glued at least partially to a corresponding portion of the film
2
, so that the line of pre-weakened resistance
31
is parallel to and approximately superimposed on a portion of the tear tape
20
, the main portion
300
of the coupon
3
is superimposed on the portion
22
of the film
2
which will subsequently remain on the pack
1
, and the other portion
301
of the coupon
3
bearing the closure line
321
is superimposed on the portion
23
of the film
2
which will be removed after opening of the pack
1
. Preferably, the face of the coupon
3
to be glued on the film
2
is self-adhesive, but it is also possible to provide for a few gluing spots or lines
33
. For good opening of the coupon
3
, it is necessary that at least the portion
331
(cf.
FIG. 1
) of coupon
3
, bearing the end of the line of pre-weakened resistance
31
at which the opening of the coupon
3
is started, be well glued by the gluing line
330
to the corresponding portion of the film
2
bearing the tear strip
20
. In this way, when the user removes the tear strip
20
, the corresponding portion of the coupon
3
remains attached thereto, and its opening is facilitated.
FIG. 6B
shows the same coupon
3
after its opening, and the opening of the film
2
, respectively. For this purpose, the user has pulled on the tear tape
20
, separating the film
2
into its two portions
22
and
23
. The main portion
300
of the coupon
3
remains attached to the portion
22
of the film
2
which remains on the pack
1
, whereas the portion
301
of the coupon
3
is disposed of with the portion
23
of the film
2
. In view of the opening of the line of pre-weakened resistance, it now becomes possible to open the coupon
3
by unfolding it about the fold
32
and to read the information contained on the inner pages
302
and
303
of the coupon
3
.
As indicated above with reference to
FIG. 5
, it is not necessary for the line of pre-weakened resistance
31
to be disposed close to the portion
320
of the coupon, but it may be disposed at any location between this portion and the fold
32
.
FIG. 7A
shows a coupon
3
according to another embodiment. The coupon
3
is essentially made up and is attached exactly in the same way as that described just previously, except that a second leaf
34
folded, e.g., in accordion pleats, and attached by gluing
340
to a portion of the face
303
of the first leaf near the fold
32
. The length of each folded page of the leaf
34
is such that these pages do not intercept the line of pre-weakened resistance
31
of the first leaf. As mentioned previously, after opening of the pack and of the coupon
3
, it is possible to get to the pages
341
to
346
of the leaf
34
in addition to the pages
302
and
303
of the first leaf.
As a modification, it is possible to dispose a self-adhesive insert
35
on any one of the pages
341
to
346
or
302
and
303
; this self-adhesive insert may represent points to be collected, a voucher for participation in a contest or a lottery, or any other object of the same kind; said insert
35
can be unstuck when the coupon
3
is open. Such an insert may obviously be provided for on a coupon according to the first embodiment described.
The embodiments described of a coupon
3
disposed on a film
2
are obviously also valid for the same coupon
3
disposed on a wrapping sheet
4
as in the embodiment of the wrapping of FIG.
3
.
FIGS. 6A and 6B
, as well as
7
A and
7
B, show two possible embodiments of a coupon
3
among numerous possibilities; in particular, the coupon
3
may be made up of more than two leaves, possibly folded or glued in a different way from what has been shown; each leaf may include a number of pages other than what has been described; the make-up of the coupon
3
may be different, e.g., in the form of a little booklet rather than of pages unfoldable in accordion pleats. The length and width dimensions of the coupon
3
are essentially determined by those of the face of the pack
1
to which the coupon
3
will be glued. It is seen in
FIGS. 1 and 3
that the coupon covers a portion of a frontal face, whereas the coupon of
FIG. 5
completely covers a face and that of
FIG. 4
partially covers two adjacent faces.
FIG. 3
shows that the coupon
3
may be of a shape other than square or rectangular. The line of weakened resistance
31
may be of any appropriate type, e.g., a tear strip, a perforated line, or a line of locally reduced thickness. Preferably, the coupon
3
closed as indicated previously and provided with its line of pre-weakened resistance
31
, provided with a self-sticking adhesion layer or not, is obtained as is from the coupon manufacturer to be applied to the wrapping as described below.
As concerns the wrapping, it has been stated that it may be a hard-type or soft-type wrapping, covered with a outside protective film or not, not exclusively intended to wrap cigarettes or other products of the tobacco industry. In fact, from the foregoing description, it is understood that a coupon
3
, according to any one of the described or possible embodiments, may be disposed on the outermost layer of any type of wrapping comprising an opening means similar to a tear tape. It may, as described, have to do with the wrapping of some sort of products of the tobacco industry, of the food industry, or another industry; the wrapping concerned here may be an outside wrapping which wraps a plurality of packs or objects of any shape, such as a wrapping of a carton of cigarettes, for example. The possible opening means or mechanism of the wrapping capable of functioning as described may be slightly different from what has been described, e.g., the tear tape
20
or
40
may be replaced by a tear thread disposed inside the wrapping and following the same path as described for the tear strip. It may also be a line of pre-weakened resistance, obtained for instance by successive perforations or, more generally, by a reduction of the mechanical resistance to traction along a given line of the wrapping, e.g., a local reduction of thickness of the wrapping sheet obtained by any known means.
Several processes can be envisaged permitting such a wrapping provided with a coupon
3
to be obtained.
FIG. 8
shows very diagrammatically a first example of a process for obtaining a wrapping provided with a coupon according any of the embodiments or modifications described. This process is based on the fact that the coupon
3
is to be placed on the outside of the wrapping and that it may therefore be placed on the pack
1
of which the wrapping is finished.
On a machine portion
5
on which the packs
1
circulate or are carried, e.g., on an endless belt
50
, in the direction indicated by the arrow, there is a distributor
51
, known per se, equipped with a reservoir filled with coupons
3
. A sensor
53
, e.g., a photoelectric cell, permits detection of the presence and position of a pack
1
within the radius of action of the distributor
51
and, via the control unit
54
, controls the actuating of the distributor
51
in order for it to place a coupon
3
on the pack
1
detected, according to a position calculated so as to cause the line of pre-weakened resistance of the coupon
3
to correspond to that of the wrapping of the pack
1
. If the back of the coupon
3
is self-adhesive, it adheres directly to the wrapping. If not, a supplementary device
55
for applying spots of glue, lines of glue, or a glued surface is also controlled by the control unit
54
in order to prepare the gluing on a pack
1
before application of the coupon
3
.
The advantage of this process is that the equipment necessary is of a very simple design, not cumbersome, and may be installed on any portion of a machine
5
where the packs I circulate as described. It may even be installed on a simple installation for the transfer of packs
1
.
FIG. 9
also shows very diagrammatically another example of a process for obtaining a wrapping provided with a coupon according to any of the embodiments or modifications described. In this case, the coupon
3
is disposed on the wrapping portion before it is applied to the object or pack to be wrapped.
The machine portion
6
shown here is, for example, the portion of a machine for preparation of a wrapping starting from a web
200
of the material intended to form the wrapping, said web being unrolled from a reel not shown in the figure. Drive means, also not shown, drive the web
200
in the direction indicated by the arrow. A cutting means, diagrammed as the rotary cutter
61
and the counter-roller
610
, sequentially cuts the web
200
in order to form the blanks intended to become the wrappings
2
. Actuating of the rotary cutter
61
is controlled by the control unit
75
. After cutting of the web
200
, the blanks are treated in a manner known per se so that each constitutes a wrapping
2
. The first line of pre-weakened resistance
20
has generally already been made longitudinally on the web
200
.
The device described above is supplemented here by a placing arm
7
known per se, used here for placing coupons
3
. The placing arm
7
includes means for supporting a first reel
70
of a tape
71
to which the coupons
3
adhere temporarily, being disposed one after the other on the tape
71
, slightly spaced from one another. The placing arm
7
also includes means for supporting a second reel
72
responsible for winding up the tape
71
after the coupons
3
have been detached from it in a manner known per se within the placing arm
7
. Each coupon
3
detached is then brought, by pneumatic or other means, onto a placing finger
73
placed in immediate proximity to the portion of the web
200
in movement immediately preceding the rotary cutter
61
, the placing finger
73
applying the coupon
3
to said portion, in such a way that the line of pre-weakened resistance
31
of the coupon is placed facing the first line of pre-weakened resistance existing on the web
200
by a correct lateral keying of the placing finger
73
relative to the width of the web
200
. A plane support surface
74
may be provided on the other side of said portion in order to offer a stable support at the time of this operation. As mentioned previously, the coupon
3
may be self-adhesive, or else glue-placing means similar to those described above may be provided for causing the coupon
3
to adhere to the web
200
. The control unit
75
ensures the synchronization of the action of the placing finger
73
with the rotary cutter
61
so that each coupon
3
is placed correctly, i.e., that its placement position along the web
200
corresponds to the location corresponding to the face of the finished wrapping on which it is to be placed.
This example of a process for placing the coupon
3
is solely illustrative of a way of applying the coupon
3
to a web
200
of the product intended to constitute the wrapping. Other devices for treatment of a web
200
are known, all generally being able to be equipped with a placement arm
7
, synchronized with some means of the machine so as to align the two lines of pre-weakened resistance and to position the coupon on the web.
It is obviously also possible to equip an installation for transferring wrapped packs, as shown in
FIG. 8
, with a placing arm
7
as shown in
FIG. 9
, just as it is also possible to equip the installation for preparing a wrapping from a web, shown in
FIG. 9
, with a distributor
51
as shown in FIG.
8
.
Tests have shown that for good simultaneous opening of the wrapping and the coupon, it is not absolutely necessary for the two lines of pre-weakened is resistance, of the coupon and of the wrapping, to be exactly superimposed, a certain lateral positioning tolerance on the order of
1
mm being permissible and/or preferred.
Although the embodiment has been described in relation to the coupon
3
, any form of information or decorative flyer can be used in place of, or in combination with, a coupon.
