Definitions
- the invention relates to the field of screw closure caps which typically include an internal threaded plastic insert and a metal outer shell. These capsules are typically intended for corking bottles containing alcoholic beverages, including wine.
- Screw closure capsules are also known whose threading is constituted by a deformation of the metallic skirt of the capsule, as described for example in the French patent. 2,387,165 .
- Capsules are also known whose shell has a skirt which has, at a certain height, a radially expanded part, as illustrated in the international patent application. WO 94/20237 .
- patent US 1,969,777 discloses a method in which a rubber piece is placed inside a closed metal tube head and said rubber member is depressed to locally deform the wall of said tube head.
- screw cap capsules of the state of the art do not always have a satisfactory manual gripping level, insofar as the unscrewing of the capsule may require a torque, in particular a first opening torque, such that the fingers may tend to slide on the metal shell, which is generally cylindrical.
- An object of the invention is constituted by a method making it possible to manufacture industrially at high speed capping caps of particular shape which are therefore more manageable, easier to screw / unscrew than those of the state of the art.
- Another object of the invention is to obtain capsules whose shape of the shell allows an immediate differentiation compared to commercially available capsules which are typically cylindrical. Moreover, these capsules must meet the requirements of mechanical strength, in particular impact strength.
- Composite capsules are made by supplying the plastic insens, the metal shells and assembling them.
- the plastic insert is formed by molding thermoplastic material, typically by injection.
- Metal shells are typically made by stamping tape or foil, usually aluminum or tin. Thus, in practice, it is known to produce industrially at high speed that cylindrical metal shells.
- the means of the invention can effectively solve the problems with regard to the capsules themselves. Indeed, the presence of an expanded radial portion on the skirt of said shell allows both to better manually grasp the capsule in particular for its unscrewing, and to differentiate from commercial capsules. Moreover, the invention makes it possible to differentiate without increasing the height of the containers clogged with such capsules. Indeed, the total height of a bottle capsulated can in many cases be a standard or a requirement imposed by one of the many actors in the chain from the producer or conditioner to the consumer. Thus, for example, it is not conceivable that a beverage dispenser is led to change the spacing between its bottle storage shelves because the height of the bottles would be too large.
- these capsules have a high impact resistance, in particular because the radially expanded portion of the outer skirt has a thickness Ep substantially the same as that of the remainder of the radially unexpanded outer skirt, whereas the expanded zones of the state of the art show thinning of the wall. Indeed, it is advantageous that this be so insofar as this expanded part (43) is exposed to shocks and where it would therefore not be mechanically weaker than the rest of the metal shell (4) . This can be achieved in particular by the method according to the invention described next.
- the figures 1a , 2a , 3a , 4a , 5 , 7a , 8a , 9a , 10a , 13a , 13b and 14a are axial sections of capsules (1) comprising a shell (4) manufactured according to the invention, said capsules being crimped onto a neck (2), whereas the figures 1b , 2b , 3b , 4b , 6b . 7b , 8b , 9b , 10b and 14b are side views of the corresponding capsules (1).
- the left part of the figure represents the capsule (1) with an attached seal (50), while on the right side the insert (50) of the left part is replaced by a sealing insert (51) which ensures a temporary solidarity of an inexplicable device (8) on the figures 1a , 4a , 10a , 13a and 13b , and a pouring device (7) on the figures 3a , 5 and 9a .
- the capsules (1) comprise an attached seal (50).
- FIGS. 1a to 5 , 13a and 13b are related to capsule methods (1) in which the insert (3) is an insert (3 ') with an inner skirt (31) called “short" of height h1 ⁇ 20 mm, so as to be opposite the threading (20) of the neck (2).
- the Figures 7a to 10b relate to capsules (1) in which the insert (3) - typically shown on the figure 6a - Is an insert (3 ") with inner skirt (31) called" long "height h1> 20 mm.
- FIGS. 14a and 14b are relative to capsules (1) in which the insert (3) is an insert (3 "') with so-called" very long "skirt of height h1> 50 mm.
- said expanded portion (43) can typically form an annular ring, continuous or discontinuous, connecting, at its upper part, typically to said outer head (40), or possibly to said cylindrical portion (42). ), and at its lower part, to said cylindrical portion (42).
- said expanded portion (43) forms a continuous annular ring of cylindrical symmetry.
- all or part of said inner skirt (31) of said insert (3) can cooperate with all or part of said typically cylindrical portion (42) of said outer skirt (41), so as to form in particular said connecting means.
- the insert (3) and said typically cylindrical portion (42) of the shell are of substantially the same diameter D1, so that said insert (3) can be introduced into said shell (4) without excessive play.
- the invention also comprises the manufacture of capsules (1) in which said expanded portion (43) could be moved away from the outer head (40) by 5 to 15 mm.
- said expanded portion (43) may form a semi-circular ring that could be facing a portion of the thread (32) of the insert (3), so that this would be without disadvantage for the screwing itself. same - case that has not been illustrated on a figure.
- said height H2 of said radially expanded portion (43) may be at least 2 mm and may typically range from 3 mm to 15 mm. In many examples illustrated by figures, this height is 4 mm, 4.5 mm, 6 mm.
- Said diameter D1 of the cylindrical portion (42) can typically range from 15 mm to 60 mm.
- the ratio D2 / D1 can range from 1.02 to 1.15 and can typically range from 1.05 to 1.10. This ratio is about 1.085 with respect to the hulls (4) of the examples and figures.
- said typically cylindrical portion (42) and said expanded portion (43) may be connected by at least one intermediate portion of average slope equal to AD / AH, with AD equal to D2-D and ⁇ H equal to the height of said shell (4) on which said diameter varies from D1 to D2, said slope typically ranging from 0.5 to 2 and preferably from 0.8 to 1.5.
- said radially expanded portion (43) and said typically cylindrical portion (42) and said expanded portion (43) are connected by a radius of curvature R2 ranging from 1.5 mm to ⁇ D / 2.
- said expanded part (43) can adjoin, at its upper part, said outer head (40), and at its lower part, said cylindrical portion (42) of said outer skirt (41), said outer head (40) and said expanded portion (43) being connected by a radius of curvature R1 ranging from 1.5 mm to 5 mm, as illustrated in FIG. figure 7a .
- said expanded portion (43) can adjoin, at its top and bottom, said cylindrical portion (42) of said outer skirt (41), said expanded skirt (43) being a spaced apart expanded skirt (43 ') or offset from said outer head (40).
- said expanded portion may be more or less remote from said outer head (40) and therefore the top of the capsule (1).
- Said outer skirt (41) may comprise several expanded parts (43, 43 ', 43 "), as illustrated by way of example on the figure 8a (right part of the figure 8a ).
- said inner head (30) of said insert (3) is facing all or part of said expanded portion (43, 43 '), so that the internal thread (32) of said threaded inner skirt (31) of said insert (3) facing said cylindrical portion (42) of said outer skirt (41).
- the expanded part (43) is of great height H2.
- the shell (4) serves as a hoop to the insert, it is preferable, particularly in the case where a thin-walled insert is used, that the part of the insert (3) bearing said thread (32) is in direct contact with said cylindrical portion (42) of substantially the same diameter and thus acting as a hoop to prevent any radial deformation of said thread (32) during screwing or unscrewing under stress.
- said inner head (30) of said insert (3) may comprise a vault (33) in contact with said sealing means (5) and, above said vault, a recessed spacing means (34), formed typically spaced concentric rings (340) in contact with said outer head (40).
- a vault 33) in contact with said sealing means (5) and, above said vault, a recessed spacing means (34), formed typically spaced concentric rings (340) in contact with said outer head (40).
- said expanded portion (43) can be positioned, in axial height, above said external thread (20) of said neck (2), and optionally at above said rim (22) of said neck (2).
- said inner skirt (31) of said insert (3) may be thick with a groove bottom ranging from 0.1 mm to 0.5 mm. In the case of a "short" skirt insert (3 '), this thickness can range from 0.1 to 0.3 mm. With inserts with longer skirt (3 ") and (3"'), the thickness of the insert can range from 0.25 to 3 mm.
- said insert (3) can be an insert (3 ') whose inner skirt (31) is called “short", said insert having a height h1 typically ranging from 6 mm to 20 mm, said height h1 corresponding typically to the height of said neck from said rim (22) to the bottom of said external thread (21).
- the H / h1 ratio can range from 1.1 to 4, and preferably from 2 to 3. This type of insert has been shown on figures 1a , 2a , 3a , 4a , 5 , 13a and 13b .
- said outer skirt (41) may comprise said tamper-proof means (6), said outer skirt (41) being able to form a crimped zone (60) under said tamper-evident ring (21), as well as said first opening means (7), said outer skirt (41) comprising a weakening line (70) solidarisant by bridges a guarantee strip (71) located above said weakening line and able to form said zone crimped (60).
- Said insert (3) can also be an insert (3 ") whose inner skirt (31) is called" long ", said insert having a height h2 typically ranging from 20 mm to 50 mm, said height h2 typically corresponding to the height said neck from said rim (22) to the bottom of said tamper evident ring (21) of said neck (2), the H / h2 ratio typically ranging from 0.8 to 1.1.

Description
L'invention concerne le domaine des capsules de bouchage à vis qui comprennent typiquement un insert intérieur en matière plastique fileté et une coque extérieure métallique.
Ces capsules sont typiquement destinées au bouchage de bouteilles contenant des boissons alcoolisées, et notamment du vin.The invention relates to the field of screw closure caps which typically include an internal threaded plastic insert and a metal outer shell.
These capsules are typically intended for corking bottles containing alcoholic beverages, including wine.
On connaît déjà des capsules composites comprenant un insert fileté et une coque métallique, comme cela apparaît notamment avec les brevets qui suivent au nom de la demanderesse.
Ainsi, le brevet français No
De même, les brevets français No

Thus, the French patent No
Similarly, French patents No
French patent No
French patent No
On connaît aussi des capsules de bouchage à vis dont le filetage est constitué par une déformation de la jupe métallique de la capsule, comme décrit par exemple dans le brevet français
Enfin, le brevet
D'une part, les capsules de bouchage à vis de l'état de la technique ne présentent pas toujours un niveau de préhension manuelle satisfaisant, dans la mesure où le dévissage de la capsule peut nécessiter un couple, notamment un couple de première ouverture, tel que les doigts peuvent avoir tendance à glisser sur la coque métallique, qui est généralement cylindrique.
Un objet de l'invention est constitué par un procédé permettant de fabriquer industriellement à haute cadence des capsules de bouchage de forme particulière qui soient de ce fait plus maniables, plus faciles à visser / dévisser que celles de l'état de la technique.On the one hand, screw cap capsules of the state of the art do not always have a satisfactory manual gripping level, insofar as the unscrewing of the capsule may require a torque, in particular a first opening torque, such that the fingers may tend to slide on the metal shell, which is generally cylindrical.
An object of the invention is constituted by a method making it possible to manufacture industrially at high speed capping caps of particular shape which are therefore more manageable, easier to screw / unscrew than those of the state of the art.
D'autre part, il y a en outre une demande toujours croissante pour une diversification des formes des capsules, de sorte qu'il y a un besoin pour des capsules non cylindriques au sens strict.
Répondre à ce besoin est un autre but important de l'invention.
Un autre objet de l'invention est d'obtenir des capsules dont la forme de la coque permet une différentiation immédiate par rapport aux capsules commercialisées qui sont typiquement cylindriques.
Par ailleurs, ces capsules doivent satisfaire aux exigences de tenue mécanique, en particulier de tenue au choc.On the other hand, there is also an ever increasing demand for a diversification of capsule shapes, so that there is a need for non-cylindrical capsules in the strict sense.
Answering this need is another important purpose of the invention.
Another object of the invention is to obtain capsules whose shape of the shell allows an immediate differentiation compared to commercially available capsules which are typically cylindrical.
Moreover, these capsules must meet the requirements of mechanical strength, in particular impact strength.
Les capsules composites sont fabriquées en approvisionnant les insens en matière plastique, les coques métalliques et en les assemblant. L'insert plastique est formé par moulage de matière thermoplastique, typiquement par injection.
Les coques métalliques sont fabriquées typiquement par emboutissage de bande ou feuille de métal, généralement d'aluminium ou d'étain. Ainsi, en pratique, on ne sait produire industriellement à haute cadence que les coques métalliques de forme cylindrique.Composite capsules are made by supplying the plastic insens, the metal shells and assembling them. The plastic insert is formed by molding thermoplastic material, typically by injection.
Metal shells are typically made by stamping tape or foil, usually aluminum or tin. Thus, in practice, it is known to produce industrially at high speed that cylindrical metal shells.
Selon l'invention, le procédé de fabrication, dont les étapes sont décrites en revendication 1, permet d'obtenir une capsule de bouchage, destinée au bouchage à vis d'un récipient destiné à contenir typiquement des boissons alcoolisées, typiquement une bouteilles ayant un goulot doté d'un filetage extérieur de vissage et d'une bague d'inviolabilité, comprend deux parties rendues solidaires en rotation et axialement par un moyen d'assemblage, a) une partie intérieure ou insert de hauteur h, en matière plastique, comprenant une tête dite intérieure et une jupe dite intérieure, ladite jupe intérieure comprenant un filetage intérieur sur sa surface intérieure destiné à coopérer avec le filetage dudit goulot de manière à pouvoir visser ladite capsule audit goulot selon un axe de rotation ou une direction axiale, et b) une partie extérieure ou coque de hauteur H, typiquement métallique ou à base de métal, comprenant une tête extérieure et une jupe extérieure masquant tout ou partie de ladite jupe intérieure en regard, ladite capsule étant typiquement dotée d'un moyen d'étanchéité, d'un moyen d'inviolabilité et d'un moyen de première ouverture, et dans laquelle :
- 1) ladite jupe extérieure de ladite coque comprend au moins une partie typiquement cylindrique de hauteur H1, de diamètre D1 adapté audit goulot, et au moins une partie radialement expansée de hauteur H2, inscrite dans un cercle de diamètre D2>D1 et formant une cavité radiale annulaire, ladite partie typiquement cylindrique de ladite coque enserrant radialement ladite jupe intérieure dudit insert à la manière d'une frette au moins en regard dudit filetage intérieur, ladite partie expansée étant destinée à faciliter notamment la préhension manuelle de ladite capsule et sa rotation par rapport audit goulot pour ouvrir / fermer ledit récipient en dévissant / vissant ladite capsule sur ledit goulot,
- 2) ladite partie radialement expansée (43) et ladite partie typiquement cylindrique (42) de ladite jupe extérieure (41) présentent typiquement une même épaisseur Ep.
- 1) said outer skirt of said shell comprises at least one typically cylindrical portion of height H1, of diameter D1 fitted to said neck, and at least one radially expanded part of height H2, inscribed in a circle of diameter D2> D1 and forming a cavity annular radial, said typically cylindrical portion of said shell radially enclosing said inner skirt of said insert in the manner of a hoop at least opposite said internal thread, said expanded portion being intended to facilitate in particular the manual gripping of said capsule and its rotation by report at said neck to open / close said container by unscrewing / screwing said capsule onto said neck,
- 2) said radially expanded portion (43) and said typically cylindrical portion (42) of said outer skirt (41) typically have the same thickness Ep.
Suite à ses travaux, la demanderesse a pu constater que les moyens de l'invention permettent de résoudre effectivement les problèmes posés en ce qui concerne les capsules elles-mêmes.
En effet, la présence d'une partie radiale expansée sur la jupe de ladite coque permet à la fois de mieux saisir manuellement la capsule en vue notamment de son dévissage, et de se différencier des capsules du commerce.
Par ailleurs, l'invention permet de se différencier sans augmenter la hauteur des récipients bouchés avec de telles capsules. En effet, la hauteur totale d'une bouteille capsulée pouvant dans de nombreux cas relever d'une norme ou d'une exigence imposée par l'un des nombreux acteurs de la chaîne allant du producteur ou conditionneur au consommateur. Ainsi, par exemple, on ne conçoit pas qu'un distributeur de boissons soit amené à modifier l'espacement entre ses étagères de stockage de bouteilles parce que la hauteur des bouteilles serait trop grande.Following his work, the applicant has found that the means of the invention can effectively solve the problems with regard to the capsules themselves.
Indeed, the presence of an expanded radial portion on the skirt of said shell allows both to better manually grasp the capsule in particular for its unscrewing, and to differentiate from commercial capsules.
Moreover, the invention makes it possible to differentiate without increasing the height of the containers clogged with such capsules. Indeed, the total height of a bottle capsulated can in many cases be a standard or a requirement imposed by one of the many actors in the chain from the producer or conditioner to the consumer. Thus, for example, it is not conceivable that a beverage dispenser is led to change the spacing between its bottle storage shelves because the height of the bottles would be too large.
Par ailleurs, ces capsules présentent une résistance élevée aux chocs, notamment parce que la partie expansée radialement de la jupe extérieure présente une épaisseur Ep sensiblement identique à celle du reste de la jupe extérieure non expansée radialement, alors que les zones expansées de l'état de la technique présentent un amincissement de la paroi.
En effet, il est avantageux qu'il en soit ainsi dans la mesure où cette partie expansée (43) est exposée aux chocs et où il ne conviendrait donc pas qu'elle soit mécaniquement plus faible que le reste de la coque métallique (4). Ceci peut être obtenu notamment grâce au procédé selon l'invention décrit ensuite.Furthermore, these capsules have a high impact resistance, in particular because the radially expanded portion of the outer skirt has a thickness Ep substantially the same as that of the remainder of the radially unexpanded outer skirt, whereas the expanded zones of the state of the art show thinning of the wall.
Indeed, it is advantageous that this be so insofar as this expanded part (43) is exposed to shocks and where it would therefore not be mechanically weaker than the rest of the metal shell (4) . This can be achieved in particular by the method according to the invention described next.

Grâce au procédé selon l'invention, ladite partie expansée (43) peut former typiquement une couronne annulaire, continue ou discontinue, se raccordant, à sa partie supérieure, typiquement à ladite tête extérieure (40), ou éventuellement à ladite partie cylindrique (42), et à sa partie inférieure, à ladite partie cylindrique (42).With the method according to the invention, said expanded portion (43) can typically form an annular ring, continuous or discontinuous, connecting, at its upper part, typically to said outer head (40), or possibly to said cylindrical portion (42). ), and at its lower part, to said cylindrical portion (42).
Sur de nombreuses figures relatives à des capsules, par exemple les figures la 1a, 2a, ladite partie expansée (43) forme une couronne annulaire continue, de symétrie cylindrique.In many figures relating to capsules, for example Figures 1a, 2a, said expanded portion (43) forms a continuous annular ring of cylindrical symmetry.
Dans ce cas, c'est cette surépaisseur radiale qui, d'une part assure une préhension manuelle plus ferme de la capsule, et d'autre part forme un signe extérieur très distinctif. Ladite partie expansée (43) délimite une cavité radiale annulaire (48) comprise entre des cylindres de diamètre D1 et de diamètre D2.In this case, it is this radial extra thickness which, on the one hand ensures a more firm manual gripping of the capsule, and on the other hand forms a very distinctive exterior sign. Said expanded portion (43) delimits an annular radial cavity (48) between rolls of diameter D1 and diameter D2.
Typiquement, tout ou partie de ladite jupe intérieure (31) dudit insert (3) peut coopérer avec tout ou partie de ladite partie typiquement cylindrique (42) de ladite jupe extérieure (41), de manière à former notamment ledit moyen d'assemblage.Typically, all or part of said inner skirt (31) of said insert (3) can cooperate with all or part of said typically cylindrical portion (42) of said outer skirt (41), so as to form in particular said connecting means.
En effet, comme cela apparaît sur les figures relatives aux capsules (1), l'insert (3) et ladite partie typiquement cylindrique (42) de la coque sont sensiblement de même diamètre D1, de manière à ce que ledit insert (3) puisse être introduit dans ladite coque (4) sans jeu excessif.Indeed, as appears in the figures relating to the capsules (1), the insert (3) and said typically cylindrical portion (42) of the shell are of substantially the same diameter D1, so that said insert (3) can be introduced into said shell (4) without excessive play.
Comme illustré sur les figures relatives aux capsules (1), tout ou partie de ladite tête intérieure (30) dudit insert (3) peut être en regard de ladite partie expansée (43) de ladite coque (4). Cependant, comme illustré sur la
Selon l'invention, ladite hauteur H2 de ladite partie radialement expansée (43) peut être d'au moins 2 mm et peut aller typiquement de 3 mm à 15 mm. Dans de nombreux exemples illustrés par des figures, cette hauteur est de 4 mm, de 4,5 mm, de 6 mm.According to the invention, said height H2 of said radially expanded portion (43) may be at least 2 mm and may typically range from 3 mm to 15 mm. In many examples illustrated by figures, this height is 4 mm, 4.5 mm, 6 mm.
Ledit diamètre D1 de la partie cylindrique (42) peut aller typiquement de 15 mm à 60 mm.Said diameter D1 of the cylindrical portion (42) can typically range from 15 mm to 60 mm.
Selon l'invention, le rapport D2/D1 peut aller de 1,02 à 1,15 et peut aller typiquement de 1,05 à 1,10. Ce rapport est d'environ 1,085 en ce qui concerne les coques (4) des exemples et des figures.According to the invention, the ratio D2 / D1 can range from 1.02 to 1.15 and can typically range from 1.05 to 1.10. This ratio is about 1.085 with respect to the hulls (4) of the examples and figures.
Comme illustré notamment sur la
Selon une modalité de l'invention, ladite partie expansée (43) peut jouxter, à sa partie supérieure, ladite tête extérieure (40), et, à sa partie inférieure, ladite partie cylindrique (42) de ladite jupe extérieure (41), ladite tête extérieure (40) et ladite partie expansée (43) étant raccordées par un rayon de courbure R1 allant de 1,5 mm à 5 mm, comme illustré sur la
Selon une autre modalité de l'invention représentée sur la
Ladite jupe extérieure (41) peut comprendre plusieurs parties expansées (43, 43', 43"), comme illustré à titre d'exemple sur la
Il peut être avantageux que ladite tête intérieure (30) dudit insert (3) soit en regard de tout ou partie de ladite partie expansée (43, 43'), de manière à ce que le filetage intérieur (32) de ladite jupe intérieure filetée (31) dudit insert (3) soit en regard de ladite partie cylindrique (42) de ladite jupe extérieure (41).It may be advantageous if said inner head (30) of said insert (3) is facing all or part of said expanded portion (43, 43 '), so that the internal thread (32) of said threaded inner skirt (31) of said insert (3) facing said cylindrical portion (42) of said outer skirt (41).
Ceci peut être avantageux dans le cas où la partie expansée (43) serait de grande hauteur H2. En effet, dans la mesure où la coque (4) sert de frette à l'insert, il est préférable, notamment dans le cas où l'on utilise un insert à paroi mince, que la partie de l'insert (3) portant ledit filetage (32) soit au contact direct de ladite partie cylindrique (42) de sensiblement même diamètre et jouant donc le rôle de frette afin d'éviter toute déformation radiale dudit filetage (32) lors d'un vissage ou dévissage sous contrainte.This may be advantageous in the case where the expanded part (43) is of great height H2. Indeed, insofar as the shell (4) serves as a hoop to the insert, it is preferable, particularly in the case where a thin-walled insert is used, that the part of the insert (3) bearing said thread (32) is in direct contact with said cylindrical portion (42) of substantially the same diameter and thus acting as a hoop to prevent any radial deformation of said thread (32) during screwing or unscrewing under stress.
Comme illustré sur les
Typiquement, quand ladite capsule (1) obture ledit goulot (2) par vissage, ladite partie expansée (43) peut être positionnée, en hauteur axiale, au-dessus dudit filetage extérieur (20) dudit goulot (2), et éventuellement au-dessus dudit buvant (22) dudit goulot (2).Typically, when said capsule (1) closes said neck (2) by screwing, said expanded portion (43) can be positioned, in axial height, above said external thread (20) of said neck (2), and optionally at above said rim (22) of said neck (2).
Selon l'invention, ladite jupe intérieure (31) dudit insert (3) peut être d'épaisseur à fond de rainure allant de 0,1 mm à 0,5 mm.
Dans le cas d'un insert à jupe "courte" (3'), cette épaisseur pourra aller de 0,1 à 0,3 mm. Avec des inserts à jupe plus longue (3") et (3"'), l'épaisseur de l'insert pourra aller de 0,25 à 3 mm.According to the invention, said inner skirt (31) of said insert (3) may be thick with a groove bottom ranging from 0.1 mm to 0.5 mm.
In the case of a "short" skirt insert (3 '), this thickness can range from 0.1 to 0.3 mm. With inserts with longer skirt (3 ") and (3"'), the thickness of the insert can range from 0.25 to 3 mm.
En effet, ledit insert (3) peut être un insert (3') dont la jupe intérieure (31) est dite "courte", ledit insert ayant une hauteur h1 allant typiquement de 6 mm à 20 mm, ladite hauteur h1 correspondant typiquement à la hauteur dudit goulot depuis ledit buvant (22) jusqu'au bas dudit filetage extérieur (21). Dans ce cas, le rapport H/h1 peut aller de 1,1 à 4, et de préférence de 2 à 3.

Then, the insert (3) is assembled to the shell (4), typically by gluing.
Par contre, pour la fabrication des capsules (1') selon les
Comme dans le cas précédent, on forme ou on approvisionne ladite ébauche (4'), puis, par déformation localisée selon l'invention, on forme ladite partie extérieure ou coque (4) comprenant ladite partie expansée (43).
Puis, on assemble le joint (50) ou l'insert d'étanchéité (51) à la coque (4).On the other hand, for the manufacture of the capsules (1 ') according to the
As in the previous case, one forms or supplies said blank (4 '), then, by localized deformation according to the invention is formed said outer portion or shell (4) comprising said expanded portion (43).
Then, the seal (50) or the sealing insert (51) is assembled to the shell (4).
A l'étape c) de ce procédé, ladite expansion radiale locale est obtenue par compression axiale d'un poinçon expansible (95) dans ladite ébauche (4') placée dans une matrice de forme (91, 91') formant une cavité radiale (92) de profil analogue à celui de ladite partie expansée (43), ledit poinçon expansible (95) plaquant une partie de ladite jupe extérieure (41') contre ladite paroi intérieure de ladite cavité radiale (92), grâce à ladite compression axiale, obtenue typiquement par déplacement axial d'un coulisseau (96).
Comme illustré sur les
Dans le cas contraire, c'est-à-dire lorsque la jupe métallique ne présente pas d'écoulement libre du côté opposé à la tête, comme illustré sur les
Il est important de noter que ladite partie expansée (43) présente sensiblement la même épaisseur que la partie dite cylindrique (42) de la jupe extérieure (41), de sorte que cette partie expansée, relativement exposée aux chocs, ne présente pas de faiblesse mécanique.In step c) of this method, said local radial expansion is obtained by axial compression of an expandable punch (95) in said blank (4 ') placed in a shape matrix (91, 91') forming a radial cavity Profile (92) similar to that of said expanded portion (43), said expandable punch (95) plating a portion of said outer skirt (41 ') against said inner wall of said radial cavity (92), by said axial compression, typically obtained by axial displacement of a slider (96).
As illustrated on
In the opposite case, that is to say when the metal skirt has no free flow on the opposite side to the head, as illustrated on the
It is important to note that said expanded portion (43) has substantially the same thickness as the so-called cylindrical portion (42) of the outer skirt (41), so that this expanded portion, relatively exposed to shocks, does not have any weakness mechanical.

Selon l'invention, ledit poinçon expansible peut être formé en une matière élastomérique apte à se déformer sous ladite compression radiale, ladite matière élastomérique présentant une dureté Shore choisie en fonction des caractéristiques mécaniques dudit matériau, typiquement métallique, de ladite ébauche (4'), ladite dureté devant être supérieure à une valeur donnée dépendant des caractéristiques mécaniques et de l'épaisseur dudit matériau formant ladite jupe (41'), de manière à ce que ladite compression axiale développe une force radiale de ladite matière élastomérique supérieure à la résistance locale à la déformation par expansion radiale de ladite jupe (41').
Ainsi, à titre d'exemple, lorsque ladite ébauche (4') est en alliage d'aluminium 8011 selon la nomenclature de l'Aluminum Association, d'épaisseur égale à 0,23 mm, un élastomère ayant une dureté Shore A de 80 à 85 convient, alors qu'un élastomère de dureté Shore A allant de 85 à 90 est nécessaire lorsque l'alliage d'aluminium est un alliage 3105 selon la même nomenclature de 0,23 mm d'épaisseur, un alliage 3105 ayant des caractéristiques mécaniques supérieures à celles d'un alliage 8011.As illustrated on
According to the invention, said expandable punch may be formed of an elastomeric material capable of deforming under said radial compression, said elastomeric material having a Shore hardness chosen according to the mechanical characteristics of said material, typically metallic, of said blank (4 ') said hardness to be greater than a given value depending on the mechanical characteristics and the thickness of said material forming said skirt (41 '), so that said axial compression develops a radial force of said elastomeric material greater than the local resistance deformation by radial expansion of said skirt (41 ').
Thus, for example, when said blank (4 ') is made of aluminum alloy 8011 according to the nomenclature of the Aluminum Association, of thickness equal to 0.23 mm, an elastomer having a Shore A hardness of 80 at 85 is suitable, whereas an elastomer of Shore A hardness ranging from 85 to 90 is necessary when the aluminum alloy is a 3105 alloy according to the same nomenclature of 0.23 mm thick, an alloy 3105 having characteristics mechanical superior to those of 8011 alloy.

L'invention présente de grands avantages.
En effet, d'une part, elle divulgue un moyen pour obtenir des déformations de grande amplitude (a/b) sur la jupe de la capsule (1) par expansion radiale localisée de la jupe, sans que pour autant ces parties déformées soient fragilisées ou présentent des défauts tels que des fissures.
Ce moyen est un procédé économique compatible avec les cadences de production industrielle, et qui peut être facilement intégré à une chaîne de production classique, l'étape d'expansion radiale localisée étant une étape complémentaire qui suit l'étape classique de formation de l'ébauche de coque (4').
Il est à noter que cette étape complémentaire fait appel à des moyens courants pour l'homme du métier et ne nécessite pas un investissement important.The invention has great advantages.
Indeed, on the one hand, it discloses a means for obtaining large amplitude deformations (a / b) on the skirt of the capsule (1) by localized radial expansion of the skirt, without these deformed parts being weakened. or have defects such as cracks.
This means is an economical process compatible with the rates of industrial production, and which can be easily integrated into a conventional production line, the localized radial expansion step being a complementary step which follows the conventional step of forming the shell blank (4 ').
It should be noted that this complementary step uses common means for the skilled person and does not require a significant investment.
D'autre part, ce procédé est d'application très large, puisqu'il est utilisable non seulement pour modifier tout type de capsule de bouchage à jupe métallique, mais encore tout corps creux, typiquement cylindrique - mais pas nécessairement cylindrique, dont la jupe est métallique ou apte à se comporter comme un métal.On the other hand, this method is of very wide application, since it can be used not only to modify any type of closure cap with a metal skirt, but also any hollow body, typically cylindrical - but not necessarily cylindrical, including the skirt is metallic or able to behave like a metal.
Enfin, les capsules (1, 1') obtenues selon l'invention présentent de grands avantages, dans la mesure où :
- elles présentent une coque métallique (4) dont la jupe extérieure (41) présente une épaisseur Ep sensiblement constante en dépit des déformations radiales locales, ce qui permet d'avoir des capsules ayant une coque exempte de défauts et de bonne tenue mécanique aux chocs,
- ces déformations radiales facilitent la préhension manuelle et la rotation de la capsule (vissage et dévissage), en particulier lors de la première ouverture de la capsule, de sorte qu'il n'est pas nécessaire d'utiliser un outil lors de cette première ouverture qui nécessite une rupture des ponts de la bande de garantie,
- ces déformations radiales constituent des moyens de décoration, d'identification et de personnalisation des capsules, ce qui est du plus haut intérêt dans la pratique.
- they have a metal shell (4) whose outer skirt (41) has a substantially constant thickness Ep despite local radial deformations, which makes it possible to have capsules having a shell free of defects and good mechanical resistance to shocks,
- these radial deformations facilitate the manual gripping and the rotation of the capsule (screwing and unscrewing), in particular during the first opening of the capsule, so that it is not necessary to use a tool during this first opening which requires breaking of the bridges of the guarantee strip,
- these radial deformations constitute means of decoration, identification and personalization of the capsules, which is of the highest interest in practice.
