Definitions
- the invention relates to the field of overcap capsules of containers or bottles containing in particular wines, alcohols, aperitifs and, in general, all alcoholic beverages. It relates more particularly overcap caps with anti-fraud means.
- caps are already known to cover the neck of a bottle already closed by a plug.
- Some caps, intended to top bottles of sparkling wines such as champagnes, are very thin caps obtained by rolling a metallic or metalloplastic skirt.
- Patent FR 2,835,510 of the applicant describes an anti-fraud means particularly well suited to this type of overcap, resulting from the introduction of a "glue point" between the top of the cap and the head of the cap : even if the skirt can still be easily unfolded, the head - which usually includes a tax stamp and / or the logo of the drink contained - is systematically destroyed during the detachment of the capsule.
- a very large number of other caps for overcapping certain bottles of wine, alcohols or liquors are thicker metal parts, typically greater than or equal to 60 ⁇ m in thickness.
- These capsules are parts which comprise a head and a slightly conical skirt and which are generally obtained by stamping-drawing a blank cut in a metal strip.
- they are placed on the neck of a bottle already closed by a stopper and are crimped, typically by crimping on a counter-glass ring present on the outer surface of the neck. from the bottle.
- European Patent EP 1 397 297 also belonging to the applicant, describes a closure system with anti-slip means. fraud particularly suitable for this type of overcap.
- the neck of the bottle has on its outer surface not only a counter-crimping ring but also a groove.
- a portion of the skirt, that opposite the throat when the cap covers the neck comprises, on all or part of its inner surface, a material
- Adhesive to form an adhesive layer capable of adhering to all or part of said groove After deformation during capping, the skirt comprises a ring-shaped portion narrowed in the groove and all or part of the necking ring adheres to the groove, thanks to the adhesive layer. In this way, any attempt at fraudulent separation of the capsule causes the rupture of the capsule and in particular of the ring narrowed in the throat, making
- the Applicant has therefore set itself the objective of defining an industrial capping process incorporating the production of a tamper-proof closure system making it possible to obtain an adhesion of the overcap capsule to the neck of the bottle which is strong enough to make impossible any removal of the capsule that would not lead to the destruction thereof, and this without increasing the risk of damage to the packaging line or substantially reduce industrial production rates.
- a first object according to the invention is a method of capping a container in which a container provided with a neck and an overcap capsule is supplied. comprising a skirt, the collar of said container is cap with said capsule and said capsule is placed on said neck, then said container with its capsule is removed, in which, to obtain a tamper-proof closure of said container, a) said skirt of such that it comprises, on at least a portion of its inner surface, a coated zone covered by an adhesive material; b) after setting up said skirt on said neck, said skirt is fixed on the neck by crimping or heat shrinking according to the nature of said capsule; characterized in that: c) said adhesive material is a heat-sealable plastic material; d) after having fixed said skirt on said neck, said skirt is locally plated on said neck, exerting a compression force on said skirt, at at least a part of said coated zone, called “compression zone", using an external tool, the active part of which normally moves on the surface of said neck, said compression force being applied
- a capsule comprising at least one skirt which is substantially cylindrical, or rather slightly conical.
- This capsule does not necessarily include a head, that is to say a transverse wall.
- the invention is of interest when the capsule performs an overcap function: the container is already plugged by a permanent-use stopper, for example a cap, and is covered with an overcap, the transverse wall of which retains said stopper for permanent use.
- This capsule serves in particular as a first-opening indicator: to access said cap, it is necessary to first destroy said capsule.
- the present invention include stamped metal caps, typically of tin or aluminum alloy, which cover most high-alcohol beverage bottles as well as plastic sleeves which preferably fill the overcap function - have a transverse wall at least partially covering said permanent-use stopper.
- the plastics material of these sleeves is heat-shrinkable.
- the present invention lends itself less well to overcap caps, usually used to cover bottles of sparkling wines, for example champagne bottles, in particular when their skirts are obtained by rolling-welding, because the conditions of the intimate contact between neck and skirt over the entire circumference, essential to avoid the risk of local melting of the skirt, are, because of conventional bending performed on this type of cap, more difficult to obtain.
- said skirt comprises, on at least a portion of its inner surface, an area called “coated zone”, covered with a heat sealable plastic material.
- a heat sealable plastic material By using such a material, it avoids the risks of strong adhesion after contact at room temperature, which can lead to a total and irreversible damage to the packaging line.
- hot-sealable plastic material is understood to mean a plastic material which, when it is brought into contact at ambient temperature, presents, with the material of the container, typically glass or a plastic material, and the materials of the packaging line, a zero or low adhesion and reversible with said materials but which, when brought to a certain temperature, called sealing temperature, generally slightly lower than the melting temperature or the glass transition temperature, present, after return to the ambient temperature, a strong and irreversible adhesion with the material of the container.
- sealing temperature generally slightly lower than the melting temperature or the glass transition temperature
- the sealing temperature of the material is greater than 45.degree. C., preferably greater than 60.degree. 75 ° C.
- Said material has a high viscosity at room temperature but, at said sealing temperature, its viscosity decreases and its surface tension becomes such that said material closely marries the relief of the surface in contact with which it is located. As the operation is reversible, this sealing temperature must be sufficiently
- the skirt and the neck have cylindrical walls, the compression force is a radial force with respect to the axis of the neck.
- intimate contact is meant a contact in which the difference between the
- Intimate contact is also understood to mean a contact in which no "delamination" is observed between the skirt and the collar which would extend over a distance that would typically have the same order of magnitude as the thickness of the skirt. To obtain an intimate contact between the zone covered with the skirt and the collar, it is therefore
- interstices resulting from the formation of such detachments.
- Applicant has associated with these interstices the appearance of defects related to the local melting of the skirt, due to the lack of rapid cooling portions of skirt that are not in direct contact with the glass. Such interstices appear in particular when one forms, voluntarily or otherwise, folds on the skirt to press it
- an external tool such as a wheel, such as the tool used in EP 1 397 297, which can be applied normally to the surface of the skirt but whose active part (the rotating part of the wheel) does not normally move to said surface of the skirt, is
- the compression zone has a certain circumferential extent, it is advantageous to aim for a force which is distributed over the contact surface and which is at all points directed in a direction as close as possible to the normal direction.
- Preferred embodiments of the invention are chosen tools that exert a normal compression force (in this case radial since skirt and neck are cylindrical at the of the compression zone), distributed substantially uniformly over the entire circumference of the skirt, for example an inflatable toroidal pocket whose interior is pressurized with hydraulic or pneumatic pressure, or an elastomeric ring which is deformed in such a way that that its internal bore decreases in diameter.
- the present method applies essentially to the metal overcap caps that are rolled and crimped around the neck or to the heat-shrinkable plastic sleeves, whose diameter, under the effect of a short current of hot air can decrease substantially, until it reaches, if it was alone, a significantly smaller diameter, typically more than 40%, to the diameter of the neck.
- Some Champagne caps quite thick and obtained by stamping, can also be well suited to the process according to the invention.
- most overcap caps for sparkling wines and champagnes which are produced by rolling-welding planar blanks made of aluminum alloy or metalloplastic, are too fine to be crimped and need to be pressed to be plated on.
- the neck of the container so that, once plated on said neck, these caps have folds and small recesses that make their skirt not intimately in contact with the neck on its entire circumference.
- the longitudinal weld resulting from the rolling-welding has dielectric properties different from the rest of the skirt, which make this type of cap unsuitable for the implementation of the preferred heating method employed in step c) of the process according to the invention. invention, namely induction.
- the sealing temperature was preferably quite high. But, preferably, it should not be too high, because the higher it is, the more it requires powerful heating means and the greater the risk of degradation is great for the capsule, the container and the liquid it contains as well as for the compression device.
- the material used itself has a temperature limit of use, for example its flash point. That is why, advantageously, the heat-sealing material is chosen such that its sealing temperature is less than 130 ° C., preferably less than 0 ° C., more preferably less than 85 ° C.
- the plastic material is a heat fusible adhesive which is deposited on the inner surface of the skirt of the capsule by application of a varnish, by projection of a liquid dispersion, or by depositing a molten thermoplastic layer.
- said inner surface is covered over its entire circumference, so that an annular coated area covered with a layer of substantially constant thickness is obtained.
- a liquid dispersion comprising an olefinic copolymer comprising acid groups, for example an EAA (ethylene-acrylic acid) copolymer.
- EAA ethylene-acrylic acid copolymer
- said heat-sealable material is used in the form of a varnish or a liquid dispersion and is deposited on the inner surface of said skirt with a spray gun, a brush or an ink-jet type technique.
- the thickness of the deposited layer is typically of the order of 10-20 ⁇ m.
- the coated zone has a shape delimited by a contour having angles, so that, by edge effect, break primers appear at the least stress on the skirt. The angles are for example made by projection through a mask.
- a sleeve prepared according to the process described by the applicant in its patent EP 1 682 331 and deposit on the inner surface of said sleeve a heat-sealing varnish or a coating of hot-melt adhesive resin (hot melt).
- hot melt hot-melt adhesive resin
- SIS rubber poly (styrene / isoprene / styrene)
- acrylic materials for example based on SIS rubber (poly (styrene / isoprene / styrene)) or acrylic materials.
- it is also possible to make the sleeve itself by coextrusion of an outer layer of a material thermoplastic suitable for a method of manufacturing shrink skirt such as that described in EP 1 682 331 and an inner layer, typically thinner, a hot melt adhesive resin.
- the quality of the glass of the bottle is also to be taken into account to determine the best hot sealing conditions. So, it is well known that the
- the bottling process ends with a finishing phase where the blank is blown internally so that it comes to be pressed. towards the inner wall of the finishing mold.
- the bottles are extracted from the finishing mold, and transferred to a conveyor belt which leads them to a surface treatment tunnel and an annealing arch.
- the temperature of the glass is still high: the outer walls of the bottle cool suddenly and contract, while the interior reacts more slowly due to the poor thermal conductivity of the material. This results in the establishment of tensile stresses at the periphery of the bottle which weaken and may cause a subsequent breakage. In order to release and equalize these stresses, the glass is heat-treated by passing through an annealing arch. In addition, in order to limit the consequences of the microdefects existing on the surface of the bottle, surface treatments are performed hot and on the cooled bottle. The hot surface treatment takes place between the exit of the finishing mold and the annealing arch. Its purpose is to prevent not only the propagation of created microcracks
- This treatment takes place at the exit of the annealing arch and consists of depositing on the surface of the bottles a protective and lubricating film, polyethylene wax type or polyoxyethylene monostearate.
- the Applicant has found that the method according to the invention gave particularly good results when the bottle was prepared. so that the neck remains raw heat treatment, that is to say, coated with the only nanometric layer of metal oxide.
- said skirt is compressed on the neck and, while maintaining said compression, heating at least a portion of said compression zone, so that said heat-sealable plastic material reaches said temperature of sealing. Because of the particularly high conditioning rates, it is preferable to perform this heating for as short a time as possible.
- the induction heating is carried out, using frequencies typically between 10 and 400 kHz, preferably between 100 and 200 kHz, and inductor powers of between 1 and 10 kW, preferably around 3 kW, which are functions of many parameters such as the distance of the inductor with respect to the zone to be heated, the geometry of the zone to be heated, the nature of the heat-sealable material, the radial compression force, etc. .
- the capsule to be heated is a heat-shrinkable plastic sleeve
- a plastic material filled with metal particles or iron oxide comprising for example at least 10% by weight of such particles.
- focus the field lines with ferrite blocks judiciously placed and limit in the space the electric field created by the inductor using for example a copper ring placed so that it protects the bottom of said skirt against edge effects.
- induction heating is carried out on the entire circumference of the capsule, targeting the part of the capsule which carries the coated zone. This is done using a solenoid comprising one or more turns completely surrounding said neck.
- a copper tube approximately 4 mm in diameter, in the form of a loop, is used as the inductor, typically a solenoid having one to five turns, preferably two / 0 or three, surrounding completely the collar.
- the targeted sealing temperature typically 80 ° C
- the level of the EAA copolymer layer 10-20 ⁇ m thick and about 20 mm wide, which covers an annular zone of the inner surface of the inner skirt.
- a tin-alloy pressed capsule said skirt having a thickness of 100 ⁇ m and a diameter of about 30 mm, using a 100-200 kHz generator associated with a solenoid-shaped inductor with three turns forming 80 diameter of approximately, connected to a generator capable of delivering a heating power of about 3.7 kW.
- the generator at 70% of its heating power, the desired sealing temperature in the area of the capsule-neck interface is reached in a time which is of the order of one second.
- a compressive force is exerted to press said skirt on the neck, with the aid of an external tool whose active part normally moves on the surface of the neck, at the level of said zone. compression.
- a device comprising jaws with substantially radial displacement surrounding the neck as completely as possible;
- an elastomeric ring that is deformed so that its internal bore decreases in diameter
- the inductor must be far enough away from said neck. For example, for a 30 mm capsule, it is in the form of one or more 80 mm diameter loops.
- the radial compression of the skirt on the collar must be effective over the entire circumference of the skirt, during the heating period and preferably a little after, during cooling. It is not easy to estimate the value of the radial compression to be applied. It is easier to define the macroscopic force imposed by the tool, which is transmitted in the form of a circumferentially distributed radial compressive stress.
- an internal pressure of between 2 and 6 bar is typically applied, depending on the shape of the force application surface and the material of the force application means used. . in the case of an elastomeric ring 52 mm in outside diameter and 32 mm in internal diameter, the elastomeric material having a hardness of the order of 40 Shore A, an axial force of the order of 1000 newtons is typically applied.
- the heating is stopped, the compression is canceled and the neck of said external tool is released.
- the layer of plastic material heat-sealable returns to room temperature, irreversible adhesion is obtained, at room temperature, between the skirt of said capsule and the wall of the container: any action intended to remove the capsule to access the permanent-use stopper results in a rupture of said capsule leaving on the neck traces very difficult or impossible to erase.
- the use of an inductor is, as we have seen, highly recommended so as to minimize heating time.
- the cooling of the layer is actually very fast because the glass, which has a large mass relative to the capsule, has not had time to heat, so that the capsule, because of its low thermal inertia, found by conduction through its entire contact surface on the neck, the ambient temperature in fractions of a second.
- the cooling it is important to have good contact between the collar and the skirt of the capsule in all places.
- the compression is maintained for a fraction of a second after stopping the heating.
- the heating energy transmitted by the inductor is so strong, it is important to ensure that the contact between the neck and the annular zone of the skirt of the capsule subjected to heating is as intimate as possible: by avoiding the presence of any gap between the skirt and the collar, as small as it is, it avoids a local fusion of the capsule that would make the container thus capsulated unsuitable for sale.
- FIG. 1 represents, in front view and in diametral section, a heat-sealing device under compression enabling the method according to the invention to be implemented inside a packaging line for bottles of spirits clogged with using a cap with a cap covered with an overcap 30 mm in diameter.
- the overcap 30 has been obtained by stamping a tin blank and has a slightly conical head and skirt.
