DEVICE FOR IRREGULARIZATION FOR CONTAINER TANK,

  TYPICALLY A BOTTLE, AND COMPOSITE BOUCHAGE CAPSULE COMPRISING SAID DEVICE FIELD OF THE INVENTION The invention relates to the field of closure caps, and more particularly that of anti-fraud caps for packaging liquid products of great value or quality. great w fame, typically in the field of wines, spirits, liqueurs or spirits. Subsequently, we will reserve the term "anti-fraud" to the refilling function, preventing or signaling any fraudulent reuse of a container by filling a different liquid from the original liquid. The term "inviolability" will be reserved for the function "witness of first ~ s opening", usually provided by a strip or a skirt connected to the capsule by a line of breakable bridges, also called "weakening line", which is detached during the first opening. STATE OF THE ART A large number of patents describing capsules providing an anti-fraud or non-refilling function are already known. Thus, by way of examples, mention may be made of French Pat. Nos. 2,730,705, 2,406,257, 2,387,166, 2,248,209, 2,738,802 and British Pat.

The international application WO 00/07898, the US Pat. Nos. 6,230,937 and 2,047,791, the British patent GB 491,737 and the French patent FR 1,087,750 are known. In spite of the large number of devices already known, none of these devices has become established in current practice as an effective means to meet the objective of making the containers equipped with these devices non-refillable or to make detectable any fraudulent reuse of a container by filling a liquid different from the original liquid; and this, either because these devices were inefficient or ineffective, or because they were too complicated to manufacture or assemble to a container. As the damage suffered by the manufacturers of branded products, for example brand-name alcohols, remains considerable, the applicant has therefore continued its research to provide a solution that is better adapted to the problem posed. DESCRIPTION OF THE INVENTION A first object according to the invention is a non-refillable device, intended to be fixed irreversibly to the neck of a container containing a liquid and to be closed by a closure cap, said device having a axis coinciding with the axis of said neck when it is fixed thereto, characterized in that it has an axial distribution duct of said liquid traversed by a transverse wall irreversibly fixed to said non-refill device and provided with a plurality of through-channels, each of said through-channels connecting an outer port, facing outwardly of the container, to an inner port, facing inwardly of the container, the smallest dimension of said outer port being smaller than a critical dimension Determined according to the critical surface tension of the constituent material 2909978 -3 of said transverse wall and where the smaller dimension of said inner port is greater than said critical dimension. According to the invention, the through channels have a variable section, this section being able to be defined by two extreme dimensions, measured along the main directions of said section. This section evolves from the inside of the container to the outside so that the smallest dimension decreases to a value below a critical value which depends on many parameters, among which the ability of the liquid to wet the surface ~ o of the transverse wall seems the most important parameter. This critical value is also a function of the viscosity of the liquid, but the latter is generally an alcohol to drink, typically a cognac, and has almost always the same viscous behavior. In a liquid (or a solid), all the bonding forces cancel each other out. Now at the surface, these bonding forces have a non-zero resultant and directed towards the interior of the liquid. The surface then behaves as if it were subjected to external pressure. The surface tension is by definition a force per unit length, it is often expressed in mN / m. The liquids concerned by the present invention are alcoholic beverages whose critical surface tension is close to 50-70 mN / m. The critical surface tension of a material is associated with the wettability of this material. The wetting of the transverse wall is primarily dependent on the surface tension of the liquid and the critical surface tension of the material constituting the transverse wall. By choosing a material whose surface tension is lower than that of the liquid, the resulting improper wetting can be used to prevent the passage of the liquid in one direction while permitting it in the other. The critical surface tension of solid substrates can be determined by the method of measuring the contact angle. A very fast determination of approximate values can be made by means of special test-inks (for example, according to ASTbA method 0 2578/67). The Applicant has found that it was first necessary to control the size of the smallest of the dimensions of the orifice: outer side, the edges and the wall of the channels being not, or being badly, wetted by said liquid. Because of the critical surface tension of the material of the transverse wall, it can not easily penetrate the through channel. On the other hand, on the inside, the edges and the entrance of the wall of the through channels are more easily wetted: the liquid can enter the channel and cross it to the outlet orifice and eject it through the dynamic effect of the liquid flow and the pressure of the liquid column still contained in the bottle. Of course, in order for the liquid contained in the container to be able to easily exit to the last drop, the smallest dimension of the external orifice must be certainly less but as close as possible to the said critical value. Preferably, said transverse wall is of a plastics material having a surface tension of between 25 and 50 mN / m and the smallest dimension of the outer orifices of the through-channels is less than 0.7 mm, while the smaller dimension their inner openings is greater than 0.7 mm. More preferably, the smallest dimension of the outer orifices is less than 0.6 mm, which makes the fraud even more difficult. Advantageously, the smallest dimension of the internal orifices is greater than 0.8 mm, which facilitates the flow of the liquid contained in the bottle. The transverse wall is substantially perpendicular to the axis of said device. Preferably, the central portion of said transverse wall is in the form of a grid having a network of through channels with sections whose form factor, defined by the ratio of the largest dimension to the smallest dimension, is less than 2, preferably close to 1. Advantageously, to facilitate the flow, the inner ports 5 have a square or rectangular shape. Said transverse wall may be flat. In this case, said through channels are all oriented substantially along the axis. In another embodiment, they are all inclined at an angle with respect to the axial direction of the device, the angle a being typically between 30 and 60. In yet another embodiment said so-called through channels are composed of two axial portions communicating with each other but offset from each other with respect to the axis. 1s Said transverse wall may also be curved and have its convexity to the outside, typically having the shape of a hemispherical dome. The through channels are then preferably inclined relative to the direction normal to said transverse wall so that they remain substantially parallel to said axial direction. Such a transverse wall can prevent or at least signal any fraudulent re-use of the container by filling a liquid different from the original liquid: to fraudulently introduce this liquid, it is necessary to inject it under pressure while in front of it. let the air in the bottle escape. Provided that the said transverse wall is given appropriate mechanical properties, the forces to be brought into play necessarily entail a destruction of the said wall. The invention therefore becomes particularly advantageous if said transverse wall is made of a sufficiently rigid and fragile material so that any fraudulent attempt to refill said container is made visible by the destruction or alteration of all or part of said transverse wall. Preferably, said transverse wall is made of polyethylene terephthalate (PET) or polystyrene (PS), in particular impact polystyrene (SB) or crystal polystyrene. It has a thickness of between 0.5 and 2 mm. In order to facilitate the destruction of the device by fraudulent manipulation, a molded one-piece device comprising a substantially cylindrical side wall to which said transverse wall is connected by means of a plurality of easily breakable N bridges, N being preferred less than 12, of unit section less than 2 mm 2, preferably less than 1 mm 2. Advantageously, said transverse wall comprises in central part a grid provided with said plurality of through channels and at the periphery a plurality of curvilinear slots, the smallest dimension of which is smaller than said critical dimension, typically for a plastic transverse wall 75 less than 0.7 mm, and preferably less than 0.6 mm. The plurality of curvilinear slots is delimited by a crown attached to said side wall by easily broken outer bridges and the said grid by inner bridges also easily scored. Preferably, each plurality of inner and outer bridges is regularly distributed and preferably angularly offset by rr / N with respect to the other plurality of bridges, N being preferably less than 12, having a unit section of less than 2 mm 2, preferably less than 1 mm 2. To be able to be fixed on the neck of the container, the non-refill device also comprises a cylindrical wall provided with at least one irreversible fixing means. This wall may have several possible aspects: a) intended to be fitted around the glass ring (so-called "out boron" device), it has an internal diameter greater than the outer diameter of the glassware ring; in this case, said irreversible fixing means may comprise: a1) at least one hook or a typically annular bead cooperating with the attachment zone of the counter-ring, or 5 a2) at least one collar, typically metallic, surrounding said ring; cylindrical wall and made integral therewith, typically by crimping, said flange being intended to be crimped on the attachment zone of the counter-ring. b) intended to be driven inside the neck (device "in bore"), said cylindrical wall has an outside diameter less than the internal diameter of the neck; in this case, said irreversible fixing means comprises at least one circular fin intended to cooperate with said inner wall of the neck, its end being, when the device is not yet inserted into said neck, at a distance from the axis from the upper device 15 to said inner diameter of the neck. The non-refillable device according to the invention is advantageously assembled to a closure cap comprising at least one metal shell provided with a metal skirt. It comprises a temporary or removable fastening means, typically a screw thread or a reversible snap-fitting bead, intended to cooperate with said composite closure cap. For this, said metal skirt is provided with a complementary temporary securing means or is assembled to an insert provided with said complementary temporary securing means. It is thus possible to obtain an autonomous assembly which comprises the closure cap itself and the non-refill device and which can be fixed on the neck in a single step during capping of the container, typically by axial depression or by screwing. We will call thereafter such a set "composite capping capsule". To facilitate the handling of said composite closure cap, said cylindrical wall 2909978 -8 is given a diameter substantially equal to that of the internal diameter of said metal skirt, and is provided with a peripheral annular groove, so that said device may be introduced inside said shell and secured thereto, typically by forming a crimping ring. In order to also give a function "inviolability" to said composite closure cap, the metal skirt is provided with an annular line of weakness which separates the metal shell in an upper part and a lower part. After rupture of the weakening zone, the upper part is part of the removable closure cap and the lower part, crimped either w on the neck or on the bottom of the refill device, remains attached to the bottle. Advantageously, the refilling device is completed with a piece forming a non-return valve. For this, the non-refillable device comprises: 1s a) an upper part carrying said transverse wall, b) a lower part adapted to ensure a tight and typically irreversible attachment of said device to said neck and having a wall defining a cavity and c) a non-return means forming a movable part in said cavity which cooperates with said lower part forming a non-return valve. The upper part is advantageously made irreversibly secured to the lower part by the cooperation of complementary assembly means belonging to each of the two parts or by the introduction of the collar which serves to fix the device on the neck and which in this case also serves as an outer ring of solidarity. To perform its role of check valve, the lower part preferably comprises a central part obstructing said cavity, typically at its upper part, so as to trap said moving means of said non-return means in said cavity. It also comprises an inner wall, provided with a lower lip delimiting a typically circular lower orifice, of surface So typically ranging from 50 to 150 mm 2. Said lower lip forms a seat cooperating with said movable part, so as to form said non-return valve, said moving part tending by gravity to close said lower orifice by being pressed against said lower lip when said container is typically straight, and axially separate from said lower seat and thus open said lower orifice when said container is inclined to pour said liquid. The lower part also comprises a transverse wall intended to form an axial stop during the attachment of said device ~ o of unloading said neck, said transverse wall bearing against the rim of said neck, so as to ensure axial positioning automatic said device with respect to said neck during said fixing. In the so-called "in boron" modes, the central portion of the lower part 15 advantageously comprises said axial duct which carries said cylindrical wall provided with at least one circular fin intended to cooperate with the inner wall of the neck. At the top of this axial duct is said transverse wall abutting on the rim of the neck and on which is fixed a flexible lip forming a pourer, typically with a thinned portion 20 forming an annular hinge. In several preferred embodiments, the lower part comprises an axial central part, the upper part is provided with a central wall on which said transverse wall is fixed and the axial distribution duct is provided with an irreversible joining means, typically a bead. inner annulus having a significant radial height, and the periphery of the transverse wall is an edge whose diameter is such that, after axial depression of said upper piece on said lower piece until the lower end of said central wall axial reaches abutment on the central part of the lower part, said edge is blocked axially upwards by said irreversible fastening means. Advantageously, the central part of the lower part is provided with reversible securing means cooperating with those of the closure cap and the axial central part of the upper piece is a sleeve inside which said securing means temporary of the lower part s and said temporary fastening means of the capsule can move and cooperate. In the so-called "out bore" modalities, the periphery of the lower part of the transverse wall is preferably fixed on the inner face of a sleeve w belonging to the upper part. Advantageously, the lower part also comprises a protection means preventing access to the non-return means, positioned above the central part of the lower part. Said protection means is for example a solid metal pellet which can move between the upper orifice of the lower piece and a ring 1s which is connected to the lower piece by a plurality of axial arms surrounding said upper orifice, and whose internal diameter is smaller than the diameter of said solid pellet. Another object of the invention is an assembly of a closure cap and an infill device, said device being temporarily or removably assembled to said closure cap, so as to be able to assemble, in a single step, said neck, when capping said container, said refill device and said closure cap. Another object of the invention is a composite closure cap comprising a closure cap and the non-refillable device according to the invention, said device being assembled temporarily or removably to said closure cap, characterized in that said capsule capping comprises a metal shell provided with a metal skirt. Preferably, said skirt comprises at least one annular line of weakness, and a crimping zone, typically annular, said line of weakness being situated above said crimping zone, said line of weakness being intended to facilitate a first opening of said capsule or to form an indication of first opening of said capsule, after said composite closure cap has closed said neck of said container during a capping phase of said container, said line of weakening delimiting an upper portion of said shell located above said line of weakness and a lower portion of said shell located below said weakening line, said lower part ~ o being crimped to said lower piece typically by spinning or crimping of said lower portion in an annular groove of said outer wall, or being to be crimped to said neck, under its glass ring. 1s FIGURES FIG. 1 a diagrammatically represents a diametral half-cup, an unreplacability device according to the invention.

It has an axial conduit (39) for dispensing said liquid through which a transverse wall (6) is fixed irreversibly to said non-refill device (3) and provided with a plurality of through channels (63). Each of the through channels (63) connects an outer port (60) facing the outside of the container to an inner port (61) facing the interior of the container. The smallest dimension of said outer orifice (60) is chosen so that it remains smaller than a critical dimension determined as a function of the critical surface tension of the material constituting said transverse wall. On the other hand, the smallest dimension of said inner orifice (61) is chosen to be greater than said critical dimension. The transverse wall (6) is made of a plastic material which has a critical surface tension of between 25 and 50 mN / m. The smallest dimension of said outer orifice (60) is less than 0.6 mm and the smallest dimension of said inner orifice is greater than 0.8 mm.

The through channels (63) are axial, that is, that is, oriented substantially in a direction normal to said transverse wall as illustrated in a of FIG. 3. In other embodiments, they are inclined differently so as to prevent, or at least impede, the introduction of a tapered object. towards the inside of the container. For example, case b) of FIG. 3a illustrates channels inclined at an angle α with respect to the axial direction (10) of the device (3), the angle a being typically between 30 and 60. In the case of c), the through channels (63) are composed of two axial prismatic parts (630, 631) communicating with each other but offset from each other with respect to the axis. The inwardly oriented portion (631) has an upper section. In Figure 3d, we have shown schematically the molding tool to obtain the transverse wall shown in 3c. We have shown in dashed versions "out bore" (Figures 5 to 9) a variant in which the wall is domed ball-shaped hemispherical. Finally, for the "in bore" versions of FIGS. 10 and 11, the transverse wall is in the form of a portion of an O-ring or a hemispherical dome without a central portion, the latter being occupied by the axial central portion (310 '). of the upper part (31 ') of the device.
