Definitions

• the present invention relates to a decorative streamer intended to surround the periphery of a food package.
• the package comprises a lateral annular wall extending between a bottom and an upper face, while the streamer extends longitudinally between two ends and has a first and a second longitudinal edge.
• This type of banner generally includes a logo representing the brand of the product, and possibly an image evoking the content and indications on the composition of the product.
• These streamers are intended to surround the periphery of the side wall of the package so that the ends of the streamer overlap, or they come edge to edge.
• Decorative streamers are very commonly used for packages containing dairy products, for example yogurt or butter, but also products such as fruit compotes and margarine.
• the upper face of the package is provided with an opening that can be closed by a tear-off lid in the case of yoghurt-type packaging, or by a removable lid as is most often used for packaging intended to contain margarine.
• the pot which forms the bottom, the side wall, and possibly part of the upper face of the package, is generally made by thermoforming a sheet of plastic material in a mold.
• the decorative streamers have an elongated rectangular shape, that is to say that they have first and second longitudinal edges rectilinear and parallel. They are usually cut from a strip of film material such as paper or plastic film, which is printed and stored as a roll before the streamers are cut. Food packaging of this type is produced in very large quantities and intended for highly competitive markets. It is therefore important to minimize the unit cost of each package without degrading its strength and aesthetic characteristics.
• the present invention therefore aims to reduce the unit cost of these packages dressed with a decorative streamer.
• the decorative streamer of the aforementioned type is characterized in that it has at least a first longitudinally extending portion having a maximum width, and at least a second portion having a minimum width, said minimum width being at least plus two-thirds of the maximum width.
• the streamer thus produced can still completely surround the package to maintain a good quality of attachment thereof, and be used in the present application processes of the banner on the packaging used.
• the first longitudinal edge is rectilinear and substantially parallel to the longitudinal axis of the streamer, this first straight edge then allowing to guide the streamer in commonly used routing devices and without significant modification thereof;
• the second edge has a convex profile along the first portion and a concave profile along the second portion, said convex profile being complementary to said concave profile, to produce in a film material the second edges of a first and a second streamer by performing a single line of cut;
• the second edge has the profile of a continuous wavy line;
• the minimum width is at least one third of the maximum width, to maintain a tensile strength that prevents the breaking of the banner during its routing during the manufacturing cycle;
• the maximum width is substantially equal to the maximum height of the side wall of the package food.
• the streamer defined above can be made from a strip of film material having patterns which define, in the width of the strip, the contour of an even number of rows of said streamers which are arranged so that the second edges of the streamers of two successive rows are adjacent, and so that the first edge of the first row and the first edge of the last row are contiguous to the longitudinal edges of the band, so as to have no drop in the band after cutting the streamers.
• a food package having a lateral annular wall extending between a bottom and an upper face, is advantageously surrounded on the periphery of the side wall by a decorative streamer as defined above, in order to reduce the overall cost of this package.
• the first portion of maximum width of the streamer is arranged on a large side of the side wall of packaging, so that this portion of the streamer is clearly visible.
• a method of manufacturing the streamer defined above which comprises a step of cutting the longitudinal edges of the streamers
• at least the cutting of the streamer second edge of the streamers is performed by a device comprising at least one mobile laser beam which makes it possible to produce varied and relatively complex cutting lines
• the cutting of the longitudinal edges of the streamers is carried out in a band of pellicular material as defined above, which passes by relative to the laser cutting device, the movements of the laser beam being synchronized with the scrolling of the strip.

• FIG. 6 is a partial schematic view of a production line of the packages represented in FIGS. 4 and 5.
• Figure 1 there is shown a decorative streamer intended to surround the periphery of a package food.
• the streamer 1 is made of a film material, that is to say thin and flexible, such as paper or a plastic film, in particular a thermoplastic material such as polypropylene.
• the choice of a particular material is determined, among other things, according to the conditions of use of the packaging and according to the method of attachment of the streamer to the package. Fixing may in particular be carried out by total or partial sizing of the streamer, or by welding in the case where it is fixed during thermoforming of the pot of the package.
• the streamer extends longitudinally along a length 1 between ends 2.
• the length 1 is determined according to the perimeter of the package for which the streamer is intended. This length can be exactly equal to the perimeter so that the ends 2 come edge to edge, or slightly greater than the perimeter to have an overlap of the ends.
• the streamer is delimited by a first longitudinal edge 3 and a second longitudinal edge 4.
• the streamer 1 has different contiguous portions which extend along the longitudinal axis of the streamer.
• these portions comprise two first portions 10 and 11 which have a maximum width L1.
• Portions 10 and 11 are also referred to as maximum width portions thereafter.
• the streamer also comprises two second portions 20 and 21 interposed between the first portions 10 and 11, which have a minimum width L2, also called reduced width portion thereafter.
• the minimum width L2 or the maximum width L1 can be reached over a whole segment (12,22) of the corresponding portion, as shown in the embodiment shown in FIG. 1, or only in one point (12,22) of each portion as shown in the embodiment in Figure 2.
• the streamers shown in Figures 1 and 2 have two portions of maximum width (10, 11) and two portions of reduced width (20, 21), but the number of portions could be different. In particular, it is possible to provide a single portion of maximum width and a single portion of reduced width.
• the minimum width L2 must be substantially smaller than the maximum width L1; in fact, the portions of reduced width (20, 21) must make it possible to reduce the total area of the streamer relative to the streamers usually used, which have a rectangular shape of width L1 and length 1. This reduction in the area of the streamer causes of course a reduction in the film material used, and therefore a reduction in the cost of the streamer.
• the minimum width L2 shall be not more than two-thirds of the maximum width L1.
• the ratio between the maximum and minimum widths (L1, L2) may vary depending on the extent of the segments or points (12, 22) over which the maximum and minimum width is reached, and depending on the economy that is sought to achieve.
• the streamer has several portions of reduced width (20, 21) it is not absolutely necessary that they all reach the same minimum width L2. It is the same for the portions of maximum width (10, 11).
• the average width of the second portions (20, 21) must be less than the average width of the first portions (10, 11). It will be noted that the retention of portions of maximum width (10, 11) allows the printing on the banner of logos and images of significant size, and preferably of size equal to those used to date, which are clearly visible by the consumer.
• the streamer made according to the invention retains its role of information vis-à-vis consumers.
• the maximum width L1 is substantially equal to the maximum height H of the side wall of the food package which will be detailed below.
• the first longitudinal edge 3 of the streamer is rectilinear and parallel to the longitudinal axis thereof.
• the rectilinear edge 3 facilitates the guidance of the streamers during their routing and facilitates their correct placement relative to the pots during the wrapping operation.
• the second longitudinal edge 4 is formed of longitudinal segments (12, 22) connected by inclined segments, so that the second edge 4 has the profile of a broken line.
• the second edge 4 can have the profile of a continuous corrugated line, as can be seen in FIG. 2. This arrangement facilitates the cutting of the second edges of the streamer, which is made using rotary knives or with a laser device detailed below.
• the profile of the second edge 4 may be a sinusoidal wavy line, but it is possible to accentuate or reduce the amplitude of the corrugations, or not to center them on the portions of maximum or reduced width, the exact profile of the corrugated line. which can be determined for aesthetic reasons.
• the second edge 4 of the streamer has a convex profile whose apex is defined by the segment or the point 12. While along the portions of reduced width (20, 21), the edge of the second edge 4 of the streamer has a concave profile whose maximum hollow is reached at the segment or point 22. As is more clearly apparent in FIG.
• the convex profiles of the portions of maximum width (10, 11) are complementary to the concave profiles of the reduced width portions (20, 21).
• the portion of reduced width 20 comprises the ends 2 of the streamer, which allows to place the area of cover or abutment ends in a less visible area of the package.
• the portion 20 has a concave profile complementary to the convex profile portions of maximum width 10 or 11.
• the minimum width L2 can be greatly reduced compared to the maximum width L1 in order to achieve a significant saving of pellicular material.
• the minimum width L2 is at least equal to one third of the maximum width L1.
• the maximum width L1 is 36 mm and the minimum width L2 is 18 mm, ie half of L2, for the embodiment of FIG.
• the streamers shown in FIGS. 1 and 2 may be cut out of a strip of film material 6 as shown in FIG. 3.
• the strip of film material 6 has patterns 7 which may cover the strip more or less completely. These patterns define the outline of the streamers that will be cut out in this band. These contours are represented symbolically by continuous lines in FIG. 3, but these are not cutting lines or pre-cuts previously made on the strip 6.
• the printed patterns 7 are printed on the strip 6 of FIG.
• FIGs 4 and 5 there is shown a food packaging 40 yogurt pot type which is surrounded by a streamer 1 made according to the invention.
• the package 40 comprises a pot 41 closed by a tear-off operculum.
• the pot 41 of thermoplastic material is produced according to a known thermoforming process, and as for example described in document FR-A-2 759 320, which consists of preheating a sheet of thermoplastic material and then stamping it into molds, a streamer being previously positioned against the side wall of said molds.
• this operation of forming the pot is generally followed by a filling operation with the food product, immediately followed by a closure operation by a lid.
• This process is carried out by an FFS production machine for Forming, Filling, Closing (Form, Fill, Seal).
• This type of packaging 40 for which is intended the streamer has a capacity generally between 10 and 500 ml, and for example about 200 ml as in the embodiment shown.
• the pot 41 has a bottom 43 which, in the embodiment shown, rises quite widely towards the side wall 44. But of course, the pot could have a cylindrical shape, and in this case, the bottom 43 would be formed solely by the lower disk of the cylinder.
• the side wall 44 is annular and extends vertically to a radially outer collar that surrounds the opening of the pot. A cap is fitted on the neck of the pot so as to form the upper face 42 of the package.
• the cross section of the package has generally the shape of a rectangle with rounded corners.
• the side wall 44 has a maximum height H in the center of the long side of the package. But in the case of a cylindrical pot, the height H of the package would be equal to the cylinder height.
• the portion of maximum width 10 of the streamer 1 is arranged on the long side of the package, as can be seen in FIG.
• the maximum width L 2 is substantially equal to the height H.
• the pattern 7 of the banner is large enough to retain the role of information and decoration of the banner.
• the width L1 of the streamer may be a few millimeters lower than the height H of the pot while maintaining the visual qualities of the streamer; for example, in the embodiment shown, the height H is 38 mm and the width L2 is 36 mm.
• a laser device comprising a mobile laser beam whose movements are controlled so as to follow the concave and convex profiles of this second edge.
• the laser can be of all types known and adapted to cut a sheet of paper or a plastic film.
• the laser device can produce a beam, or several clipping beams as in the case of the device 50 shown in Figure 6.
• the movements of the beam or beams are created by servomotors acting for example on mirrors.
• the servomotors are themselves controlled by a device of control 51 which contains one or more servo servo programs so that the laser beams perform one or more cutting lines.
• a laser device thus makes it possible to cut the second longitudinal edge 4 of the streamers in a complex pattern and offers the possibility of passing almost instantaneously from the production of a first form of streamer to a second form of streamer, simply by addition of a code in the control device 51.
• a laser device has the advantage over a device with rotating knives or cutting dies, not to undergo wear phenomena, or phenomena of fouling, which is particularly important in the field of food packaging.
• the rectilinear edges can also be cut by a laser beam.
• the cutting of the streamers by the laser cutting device is preferably carried out in a strip of film material as described above.
• the strip 6, stored in the form of a roll is unwound so as to scroll relative to the laser cutting device 50 disposed transversely relative to the direction of travel. Due to this movement of the strip 6 relative to the device 50, it is possible to control the displacement of the beams only in a direction transverse to the strip, which avoids having to control an additional movement in the longitudinal direction of the banners.
• a device 52 adapted to detect the movement of the strip 6 is connected to the control device 51 in order to synchronize the movements of the laser beams with the scrolling of the strip.
• the device 52 may be an optical recognition device for the printed patterns on the tape or any other marking affixed to it.
• the cutting of the strips is integrated in the machine for manufacturing the packaging pots 41.
• thermoforming station which comprises molds represented symbolically by the reference 55.
• the step cutting of the longitudinal edges is followed by a step of routing the strips 31, 36 corresponding to the rows of the strip 6 which have been cut longitudinally.
• This routing step is performed using pulleys and references 57 of known types, and does not require significant changes with the first straight edge 3 which facilitates the guiding of the strips. It will be noted that during the routing of the streamers, the even rows (32, 34, 36) undergo reverse rotation relative to the odd rows (31, 33, 35) to arrive at the molding stations with the same vertical orientation .
• the streamers are introduced into them before thermoforming the pots and cut transversely using a cutting knife system known to form the ends of the streamers.
• a cutting knife system known to form the ends of the streamers.
• it is a machine for making six pots simultaneously, but of course, it could be a machine to achieve twelve or twenty-four pots at a time.
