LEDIT DEVICE

FIELD OF THE INVENTION

The invention relates to the field of capping capsules, and more particularly that of anti-fraud capping capsules for packaging liquid products of great value or of great renown, typically in the field of wines, alcohols, 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 "first opening control" function, generally provided by a strip or skirt connected to the capsule by a line of breakable bridges, also called "line of weakening", which is detached during of 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, 2,406,578, 2,387,166, 2,248,209, 2,738,802 and British Pat.

Despite 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 any fraudulent reuse detectable. 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 branded spirits, remains considerable, the plaintiff has therefore continued its research to provide a better solution to the problem.

DESCRIPTION OF THE INVENTION

A first object according to the invention is an irreplacability device, intended to be irreversibly fixed to the neck of a container containing a liquid and to be closed by a closure cap, said device having an axis coinciding with the axis. said neck when attached 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 orifice, facing the outside of the container, to an inner orifice, facing the interior of the container, the smallest dimension of said external orifice being smaller than a critical dimension determined according to the tension of the critical surface of the constituent material of said transverse wall and wherein the smallest dimension of said inner port is greater than said critical dimension.

According to the invention, the through channels have a variable section, this section can 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 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 bond 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 depends primarily on the liquid surface tension 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. - AT -

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 ASTM method 02578/67).

The applicant has found that it was first necessary to control the size of the smallest dimension of the orifice: outer side, the edges and the wall of the channels not being, or being badly wetted by said liquid due to the critical surface tension of the material of the transverse wall, the latter can not penetrate easily into 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 flow of the liquid and the pressure of the column of liquid 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 made of a plastic 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 of their inner holes are 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 present 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 on the smallest dimension, is less than 2, preferably close to 1. Advantageously to facilitate flow, the inner holes 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 to the axial direction of the device, the angle is 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.

Said transverse wall may also be curved and have its convexity towards 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 makes it possible to prevent or at least to report any fraudulent reuse 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 having to leave to escape the air contained in the bottle. 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 scored N bridges, N being preferably 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 transverse plastic wall, 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 π / N relative to the other plurality of bridges, N being preferably less than 12, of unit section 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 (device called "out bore"), it has an internal diameter greater than the outer diameter of the glassware; 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 a2) at least one flange, typically metallic, surrounding said wall cylindrical 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 the device greater than 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 securing 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 closure cap". To facilitate the handling of said composite closure cap, said wall is given a cylindrical diameter substantially equal to that of the inner diameter of said metal skirt, and it is provided with a peripheral annular groove, so that said device can be introduced into said shell and secured thereto, typically by formation of 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 breaking the weakening zone, the upper part is part of the removable cap closure and the lower part, crimped either 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: 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 means non-return forming a movable part in said cavity which cooperates with said lower part forming a non-return valve.

The upper part is advantageously 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 the occurrence also serves as an outer ring of solidarity.

To ensure its role of check valve, the lower part preferably comprises a central portion 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 includes an interior wall, 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 being pressed against said lower lip when said container is typically straight, and to separating axially from said lower seat and thus opening 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 refilling device to said neck, said transverse wall bearing against the rim of said neck, so as to ensure automatic axial positioning of said device relative to said neck during said fixing.

In the so-called "in boron" modes, the central part of the lower part 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 arriving in abutment on the rim of the neck and on which is fixed a flexible lip forming a pourer, typically with a thinned portion 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 axial wall abuts on the central part of the lower part, said edge is blocked axially upwards by said irreversible fastening means. Avαntαgeusement, the central part of the lower part is provided with reversible securing means cooperating with those of the closure cap and the central axial portion of the upper part is a sleeve inside which said means for temporarily securing the lower part and said means for temporarily securing 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 internal face of a sleeve 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 which is connected to the lower piece by a plurality of axial arms surrounding said upper orifice, and whose internal diameter is less than the diameter of said solid pellet.

Another object of the invention is an assembly of a closure cap and a non-refill device, said device being temporarily or removably assembled to said closure cap, so as to be able to assemble in a single step , at said neck, during the capping of said container, said non-refill device and said closure cap.

Another object of the invention is a composite closure capsule comprising a closure cap and the non-refill device according to the invention, said device being temporarily or removably assembled to said closure cap, characterized in that said capsule capping includes a metal shell with a metal skirt. Preferably, said skirt comprises at least one weakening line annular, and a crimping zone, typically annular, said line of weakness being located above said crimping zone, said weakening line 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 weakness delimiting an upper portion of said shell above said line of weakness and a lower part of said shell located below said line of weakness, said lower part being crimped to said lower part typically by embossing or crimping of said lower part in an annular groove of said outer wall, or being intended to be crimped on the neck, under his glass ring.

EXAMPLES OF REALIZATION

A. Transverse Wall (Figures 1a, 1b and 2, Figures 5 to 9, Figure 3, Figures 10 and 11) Figure la illustrates the characteristics common to all the non-refill devices according to the invention: said device has an axis (10) which coincides with the axis of the neck (40) of the container when it is attached thereto. 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 transverse wall (6) present in the form of a grid having a network of through channels having approximately square sections which gradually decrease from the inside to the outside.

The transverse wall (6) is curved and has its convexity outwardly, typically having the shape of a hemispherical dome. It is made of a sufficiently rigid and fragile material 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 the device and the transverse wall are molded in one piece, of a material such as shock polystyrene or crystal polystyrene. The axial distribution duct (39) and the transverse wall (6) are connected via a plurality of bridges (65) whose section is less than 1 mm ² . The transverse wall (6) comprises in the central part a grid provided with said plurality of through channels (63) and at the periphery a plurality of curvilinear slots (64), the smallest dimension of which is less than 0.6 mm. Said plurality of curvilinear slots is delimited by a ring gear (67) attached to said axial duct (39) by 8 regularly distributed outer bridges (65) and said grid (6) by 8 regularly spaced inner bridges (66) angularly offset from each other. π / 8 with respect to the outer bridges (67).

In the more specific examples given in FIGS. 5 to 9, the transverse wall (6a) is presented flat and perpendicular to the axis, like the walls illustrated in FIG. 3. The through channels (63) are axial, ie said oriented substantially in a direction normal to said transverse wall as illustrated in Figure 3 a). In other embodiments, they are inclined differently so as to prevent, or at least impede, the introduction of a tapered object towards the interior of the container. For example, the case b) of Figure 3a illustrates channels inclined at an angle with respect to the axial direction (10) of the device (3), the angle is typically between 30 and 60 °. In the case 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 diagrammatically represented 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 an O-ring portion 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.

B. Attachment to the neck

The set of non-refillable devices according to the invention have a cylindrical wall (36, 36 ') provided with at least one irreversible fastening means to said neck.

B.1 Snap fit (Figures 1a, 4, 5 and 6)

In these examples, said cylindrical wall (36) has an internal diameter greater than the external diameter of the glass ring and the irreversible fixing means is a hook (360) cooperating with the attachment zone (405) of the counter-ring. (403).

B.2 Crimp fixation (Figures 7, 8 and 9)

In these examples, said cylindrical wall (36) has an internal diameter greater than the outer diameter of the glass ring and said irreversible fixing means comprises at least one metal collar (38) which surrounds said cylindrical wall (36) and which is integral with the latter, said collar being intended to be crimped on the attachment zone (404) of the counter-ring (403). The flange (38) has been secured to said cylindrical wall (36) by at least one crimping on an upper peripheral annular shoulder (362) adjacent to said cylindrical wall (36).

B.3 Insertion Fixation Inside the Neck (Figures 10 and 11) In these examples, said cylindrical wall (36 ') has an outside diameter smaller than the internal diameter of the neck (40) and said irreversible fixing means comprises less a circular fin (334) intended to cooperate with said inner wall of the neck, its end being, when the device is not yet introduced into said neck, at a distance from the axis (10) greater than said internal diameter of the neck. It may comprise a complementary attachment means (7) to the neck (40) comprising either an adhesive (70) carried by the surface of said fin (334) (Figure 10) or an elastomeric ring seal (71) placed on the wall cylindrical (36 ') (Figure 11), or both, so as to ensure the sealing of said device (3) to said neck (40).

C. Inviolability (or "first-open" control) (Figures 4, 5, 6, 7, 9, 10, 11) With the exception of the example of Figure 8, which has a single capsule, without a control inviolability, the capsules of Figures 4, 5, 6, 7, 9, 10 and 11 are inviolable composite capsules (1).

The non-refill device is provided with a temporary securing means, typically a screw thread (370) (FIGS. 4 to 7 and 9) or a reversible snap-on bead (371) (FIGS. 10 and 11) intended for cooperate with the closure cap (2). The latter includes a metal shell

(20) of which said metal skirt (200) is provided with complementary temporary fastening means (204) (FIG. 7) or which is assembled to an insert

(21) or a shutter (2T) provided with said complementary temporary fastening means (214 complementary to 370, FIG. 4 (identical system in the examples of FIGS. 5, 6, 8 and 9), (214 'complementary to 371, FIGS. and 11) .The temporary assembly of the refill device and the capsule forms a "ready-to-install" composite capsule on the neck of a container.

During capping, the composite capsule is placed on the neck by axial depression until the transverse portion (34, 34 ') of the lower piece (30, 30') abuts the rim (400). ) (with the exception of the device of Figure 4, which is monobloc and therefore has no lower part, but for which the fixing happens in the same way, mutatis mutandis). The "out bore" devices of FIGS. 4, 5 and 6 are snapped onto the glass ring. With regard to the other "out bore" devices (FIGS. 7 and 9) and the "in bore" devices (FIGS. 10 and 11), the skirt (200) of the metal shell (20) is crimped onto the zone of hooking (404) of the counter ring (403).

For all these examples ("out bore" snapped in FIGS. 4, 5 and 6, "out bore" not snapped from FIGS. 7 and 9 and "in bore" of FIGS. 10 and 11), the skirt (200) of the shell ( 20) is provided with a weakening band (201). The weakening line (201) is intended to facilitate a first opening of the capsule (2) or to form an indication of first opening of said capsule (2). It delimits an upper portion (202) of the shell (20), located above said line of weakness (201), and a lower portion (203) of said shell (20) located below said line of weakening (201).

Regarding the capsules with "out boron" device not latched and "in bore", the lower portion (203) has a zone (205) which is crimped to the neck under its glass ring (401). With regard to the capsules with an "out bore" device, the lower part (203) has a zone (206) which is crimped on the lower part (30), in an annular groove (361) of the outer wall (36). ). D. Two-part irreplacability device comprising a non-return valve of 5, 6, 7, 8, 9, 10, m

This device comprises an upper piece (31, 31 ') carrying said transverse wall (6, 6') and a lower piece (30, 30 ') delimiting a cavity (300, 300'), said lower piece (30, 30 ') ) being able to ensure a tight and typically irreversible fixation of said device (3, 3 ') to said neck (40), and a non-return means (5) forming a part (50) movable in said cavity and cooperating with said lower part (30, 30 ') forming a non-return valve.

Said upper piece (31, 31 ') is rendered irreversibly integral with said lower piece (30, 30'), a) thanks to the cooperation of complementary assembly means belonging to each of the two pieces:

• annular beads (302) on the lower part and (312) on the upper part. These beads are illustrated in Figure 5, but not shown in Figures 6 and 7.

• beads (302 ') formed on the upper end of the axial distribution duct (39') cooperating with the periphery (68 ') of the transverse wall (ό ¹ ) ("in bore" versions, illustrated in FIGS. 11) b) or thanks to the establishment of a flange (38) which acts as an outer fixing ring and is also used for fixing on the neck (illustrated in Figures 7, 8 and 9).

The lower part (30, 30 ') comprises a central part (301, 301') obstructing said cavity (300, 300 ') at its upper part, so as to trap said moving means (50) of said non-return means (5). ) in said cavity (300, 300 '). Said lower piece (30, 30 ') comprises an inner wall (33, 33'), provided with a lower lip (330, 330 ') delimiting a typically circular lower orifice (331, 331') of surface So typically ranging from 50 to 150 mm 2, said lower lip forming a seat cooperating with said movable part (50), so as to form said non-return valve, said moving part (50) gravity tending to close said lower orifice by being pressed against said lower lip when said container is typically straight, and to separate axially from said lower seat and thus to open said lower orifice when said container (4) is inclined to pour said liquid.
