Description

La présente invention se rapporte à une capsule à vis à verseur selon le préambule de la revendication 1 pour le bouchage d'un col de récipient obturé jusqu'à la première utilisation par un opercule perforable.The present invention relates to a pouring screw cap according to the preamble of claim 1 for sealing a container neck closed until first use with a perforable seal.

Une capsule de ce type est connue, par exemple, par le document EP-A-0 214 095. Suivant la figure 4 de ce document, une capsule à vis présente une paroi d'extrémité munie d'un orifice verseur central et d'une dent coupante comprenant une pointe centrale et un flanc latéral dont la fonction est de déplacer vers l'extérieur l'opercule partiellement découpé, lors du vissage à fond de la capsule sur le col de récipient, après arrachage d'une bande de garantie du type « cliquet », prolongeant vers le bas la jupe extérieure du corps de capsule.A capsule of this type is known, for example, from document EP-A-0 214 095. According to Figure 4 of this document, a screw cap has an end wall provided with a central pouring orifice and a cutting tooth comprising a point central and a lateral flank whose function is to move outward the cover partially cut out, when screwing the cap on the container neck, after tearing off a "ratchet" type guarantee strip, extending downwards the outer skirt of the capsule body.

Suivant le document EP-A-0 268 538, une capsule à vis comporte, pour la perforation d'un opercule perforable obturant un col de récipient, soit un perforateur bistable prévu sur la paroi d'extrémité du corps de la capsule, ce qui permet, lorsque la capsule est vissée à fond sur le col de récipient, de perforer l'opercule et de le découper ensuite en arc de cercle par dévissage de la capsule (voir en particulier figure 5), soit un perforateur bistable prévu sur un couvercle pivotant de la capsule, de manière à pouvoir être enfoncé dans un orifice verseur de la capsule et perforer ainsi l'opercule du col de récipient.According to document EP-A-0 268 538, a screw cap comprises, for the perforation a perforable cover sealing a container neck, or a bistable perforator provided on the end wall of the capsule body, which allows, when the capsule is screwed fully onto the container neck, perforate the lid and then cut it into circular arc by unscrewing the capsule (see in particular Figure 5), i.e. bistable perforator provided on a pivoting cap of the capsule, so that be inserted into a pouring orifice of the capsule and thus perforate the lid of the neck of container.

Ces capsules connues ne donnent pas satisfaction dans la mesure où il arrive que l'opercule, après perforation, obture encore plus ou moins le col du récipient ou l'orifice verseur de la capsule, gênant ou perturbant ainsi la distribution du produit contenu dans le récipient.These known capsules are not satisfactory since it happens that the seal, after perforation, more or less seals the neck of the container or the orifice pourer of the capsule, thus interfering with or disrupting the distribution of the product contained in the recipient.

Par ailleurs, la capsule suivant le document EP-A-0 268 538 ne permet pas, à un utilisateur non averti, de se rendre clairement compte, au moment de l'achat du produit conditionné dans un récipient bouché à l'aide d'une telle capsule, si l'opercule est encore intact ou non. Furthermore, the capsule according to document EP-A-0 268 538 does not allow, at a uninformed user, to be clearly aware, when purchasing the product packaged in a stoppered container with such a capsule, if the seal is still intact or not.

Le document JP-A-07 330009 (correspondant au préambule de la revendication 1) décrit une capsule comprenant un embout verseur formant une voie de passage, ainsi que deux couteaux qui font saillie dans le prolongement du bord circulaire de la voie de passage, formés en séparant par une fente un corps semi-cylindrique, les coins de cette fente constituant des arêtes tranchantes orientées dans le sens de rotation du corps de capsule, qui coupent un opercule en aluminium en y traçant deux lignes de découpe, l'opercule n'étant pas déchiré de force, l'aire de l'ouverture pratiquée dans l'ouverture restant petite.Document JP-A-07 330009 (corresponding to the preamble of claim 1) describes a capsule comprising a pouring nozzle forming a passageway, as well as two knives which project into the extension of the circular edge of the passageway, formed by separating with a slits a semi-cylindrical body, the corners of this slit constituting edges cutting edges oriented in the direction of rotation of the capsule body, which cut a aluminum cover by drawing two cutting lines on it, the cover not being forcibly torn, the area of the opening in the opening remaining small.

Ce type de capsule présente également un certain nombre d'inconvénients.This type of capsule also has a number of drawbacks.

Notamment, les couteaux ne permettent pas une découpe de l'opercule suffisante pour dégager totalement la voie de passage, de sorte que cette capsule est limitée aux applications dans lesquelles le produit contenu dans le récipient sur lequel elle est rapportée, est de consistance suffisamment liquide ou fine pour passer par la fente. entre les couteaux.In particular, the knives do not allow the lid to be cut enough to completely clear the passageway, so that this capsule is limited to applications in which the product contained in the container on which it is added, is of a sufficiently liquid or fine consistency to pass through the slit. between the knives.

Ainsi, ce type de capsule n'est pas adapté dans le cas de condiments contenant des grumeaux ou des morceaux de taille supérieure au passage ménagé par la fente, et qui obturent alors celle-ci.Thus, this type of capsule is not suitable in the case of condiments containing lumps or lumps larger than the passage through the slit, which then close it.

Par ailleurs, le comportement mécanique des opercules varie en fonction des matériaux qui le composent.In addition, the mechanical behavior of the lids varies according to the materials that make it up.

Un opercule en aluminium, tel que décrit dans le document JP-A-07 330009, a une tendance systématique à se déformer plastiquement, de sorte que la partie découpée conserve la configuration adoptée sous l'effet de la pression du produit qui s'échappe par l'orifice verseur.An aluminum cover, as described in document JP-A-07 330009, has a systematic tendency to deform plastically, so that the cut part keeps the configuration adopted under the effect of the pressure of the escaping product through the pouring orifice.

Par contre, un opercule réalisé à partir d'une feuille d'aluminium doublée d'une feuille en matière synthétique se déforme en général élastiquement, de sorte que la partie découpée a tendance à conservée sa position d'origine, et à obturer de ce fait l'ouverture que l'on souhaite pratiquer dans l'opercule. On the other hand, a cover made from an aluminum sheet lined with a sheet in plastic material usually deforms elastically, so that the part cut-out tends to keep its original position, thereby closing off the opening that you want to make in the cover.

Ainsi, le seul fait de pratiquer une découpe dans un opercule de ce type ne se révèle pas suffisant pour y pratiquer une ouverture permettant de dégager complètement l'orifice verseur.Thus, the only fact of practicing a cut in a cover of this type does not appear not enough to make an opening to completely clear it the pouring orifice.

La présente invention vise une capsule à vis à verseur qui, tout en étant de structure simple et de coût réduit, puisse être utilisée pour le bouchage d'un col de récipient obturé par un opercule perforable, et permette moyennant une manipulation simple, de pratiquer dans l'opercule une ouverture qui dégage complètement l'orifice verseur de sorte à permettre une distribution directe du produit contenu dans le récipient, sans que l'écoulement du produit ne soit gêné en aucune manière, et ce quels que soient les matériaux dont est composé l'opercule.The present invention relates to a pouring screw capsule which, while being of structural simple and low cost, can be used for sealing a container neck closed by a perforable cover, and allows, by means of simple manipulation, to make an opening in the cover that completely releases the pouring orifice so as to allow direct distribution of the product contained in the container, without the flow of the product is not hindered in any way, whatever the materials of which the cover is made.

L'invention vise par ailleurs une capsule à vis à verseur offrant à un utilisateur même non averti une meilleure garantie quant à l'état de l'opercule du col de récipient (témoin d'inviolabilité).The invention further relates to a pouring screw capsule offering a user even not warned a better guarantee as for the state of the lid of the container neck (witness tamperproof).

A cet effet, un objet de l'invention est une capsule à vis à verseur pour le bouchage d'un col d'un récipient obturé jusqu'à la première utilisation par un opercule perforable, comprenant :

  • un corps de capsule présentant une paroi d'extrémité munie d'un orifice verseur ;
  • une jupe saillant de la dite paroi, cette jupe présentant un filetage intérieur pour la fixation du corps de capsule par vissage sur le col du récipient selon un axe de rotation ;
  • un moyen pour pratiquer une ouverture dans l'opercule, qui comprend une dent saillant de la dite paroi d'extrémité, cette dent étant située à distance de l'axe de rotation du corps de capsule, cette dent étant apte à suivre une trajectoire circulaire lors du vissage du corps de capsule sur le col du récipient dans un sens,
la dite dent étant située à distance de l'orifice verseur en étant distincte de celui-ci. la distance entre l'axe de rotation et la dent étant supérieure à la distance entre l'axe de rotation et l'orifice verseur, la dent étant conformée et orientée pour perforer l'opercule puis y pratiquer une ouverture par déchirement de l'opercule, et pour repousser devant elle la partie déchirée de l'opercule (6) lors du vissage. To this end, an object of the invention is a pouring screw cap for plugging a neck of a container closed until the first use by a perforable cover, comprising:
  • a capsule body having an end wall provided with a pouring orifice;
  • a protruding skirt of said wall, this skirt having an internal thread for fixing the capsule body by screwing on the neck of the container along an axis of rotation;
  • means for making an opening in the cover, which comprises a tooth projecting from said end wall, this tooth being located at a distance from the axis of rotation of the capsule body, this tooth being able to follow a circular trajectory when screwing the capsule body on the neck of the container in one direction,
said tooth being located at a distance from the pouring orifice being distinct from the latter. the distance between the axis of rotation and the tooth being greater than the distance between the axis of rotation and the pouring orifice, the tooth being shaped and oriented to perforate the cover then make an opening by tearing the cover , and to push in front of it the torn part of the cover (6) during screwing.

De la sorte, l'ouverture ainsi pratiquée englobe l'orifice verseur et permet un écoulement direct du produit contenu dans le récipient par l'orifice verseur.In this way, the opening thus made includes the pouring orifice and allows a direct flow of the product contained in the container through the pouring orifice.

La dent peut présenter un profil en T, et comprendre une paroi incurvée à concavité tournée vers l'axe de rotation.The tooth may have a T-profile, and include a curved wall with a concavity facing the axis of rotation.

Selon un mode de réalisation, cette paroi présente une surface agencée pour appuyer sur l'opercule en lui appliquant une force suivant une direction formant un angle avec une direction tangente à la trajectoire au niveau de la dent.According to one embodiment, this wall has a surface arranged to support on the operculum by applying a force to it in a direction forming an angle with a direction tangent to the trajectory at the level of the tooth.

Par ailleurs, la dent peut comprendre un tenon saillant de la paroi en direction de l'axe de rotation.Furthermore, the tooth may include a stud projecting from the wall in the direction of the axis. of rotation.

Par exemple, la dent est biseautée pour former une pointe apte à perforer l'opercule.For example, the tooth is bevelled to form a point capable of perforating the cover.

Selon un mode de réalisation, l'orifice verseur est également excentré, la dent étant excentrée du même côté que l'orifice verseur.According to one embodiment, the pouring orifice is also eccentric, the tooth being eccentric on the same side as the pouring orifice.

Par exemple, la dent et l'orifice verseur sont excentrés de manière que leurs bords situés en avant dans le sens de vissage de la capsule sur le col se trouvent sensiblement sur un même rayon.For example, the tooth and the pouring opening are offset so that their edges located forward in the direction of screwing the capsule on the neck are substantially on the same radius.

La hauteur de la dent est de préférence inférieure au pas du filetage du corps de capsule.The height of the tooth is preferably less than the pitch of the thread of the body capsule.

Ainsi, l'opercule n'est jamais déchiré complètement, mais reste toujours attaché au col du récipient, sans gêner la distribution du produit par l'orifice verseur.Thus, the lid is never completely torn, but always remains attached to the collar of the container, without interfering with the distribution of the product through the pouring orifice.

Selon un mode de réalisation, la capsule comprend en outre une bague de garantie arrachable prolongeant la jupe du corps de la capsule sur une hauteur supérieure à la hauteur de la dent et prenant appui sur une surface d'appui du récipient de manière à maintenir la dent au-dessus de l'opercule. According to one embodiment, the capsule also comprises a guarantee ring tear-off extending the skirt of the capsule body to a height greater than the height of the tooth and bearing on a bearing surface of the container so as to keep the tooth above the seal.

Cette bague de garantie comprend par exemple des moyens coopérant par encliquetage avec un bourrelet extérieur d'accrochage situé sur le col du récipient entre le filetage et la dite surface d'appui.This guarantee ring comprises for example means cooperating by snap-fastening with an external hanging bead located on the neck of the container between the thread and the said bearing surface.

La présence de cette bague de garantie réalisée en une seule pièce avec le corps de la capsule, permet de visser la capsule sur le corps de récipient jusqu'à encliquetage de la bague de garantie sur le col, ce qui fait que, sauf arrachement de la bague de garantie, ce qui est nettement visible, la capsule se trouve reliée de façon imperdable au récipient, sans risque de perforation de l'opercule.The presence of this warranty ring made in one piece with the body of the cap, allows the cap to be screwed onto the container body until the warranty ring on the collar, which means that, unless the warranty ring is torn off, which is clearly visible, the capsule is connected in a captive manner to the container, without risk of perforation of the lid.

L'utilisateur, en achetant le produit conditionné dans le récipient bouché par la capsule pourvue de sa bague de garantie intacte, a ainsi l'assurance que l'opercule du récipient n'est pas percé.The user, buying the product packaged in the container closed by the capsule provided with its intact guarantee ring, thus has the assurance that the lid of the container is not pierced.

A la première utilisation, l'utilisateur arrache la bande de garantie et visse ensuite la capsule à fond sur le col, ce qui provoque automatiquement la perforation et le déchirage de l'opercule, sans que ce dernier ne puisse gêner de quelque manière que ce soit la distribution du produit, en venant interférer avec l'orifice verseur.On first use, the user tears off the guarantee strip and then screws the capsule fully on the neck, which automatically causes perforation and tearing of the cover, without the latter being able to hinder in any way this is the distribution of the product, coming to interfere with the pouring orifice.

En outre, la capsule peut comprendre un couvercle relié par la charnière au corps de capsule, en vue de l'obturation de l'orifice verseur du corps de capsule.In addition, the capsule may include a cover connected by the hinge to the body of capsule, for closing the pouring orifice of the capsule body.

En se référant aux dessins annexés, on va décrire ci-après plus en détail un mode de réalisation illustratif et non limitatif d'une capsule de bouchage conforme à l'invention ; sur les dessins :

  • la figure 1 est une coupe axiale d'un col de récipient obturé par un opercule perforable, et d'une capsule de bouchage vissée sur le col, avant destruction de l'opercule ;
  • la figure 2 est une coupe selon la figure 1 après destruction de l'opercule ;
  • la figure 3 est une vue de dessous de la capsule selon les figures 1 et 2 ;
  • les figures 4a et 4b sont des vues schématiques prises de l'intérieur du récipient, montrant, l'une l'opercule intact et l'autre l'opercule déchiré après vissage de la capsule à fond sur le col du récipient.
Referring to the accompanying drawings, there will be described below in more detail an illustrative and nonlimiting embodiment of a closure cap according to the invention; on the drawings:
  • Figure 1 is an axial section of a container neck closed with a perforable cover, and a closure cap screwed onto the neck, before destruction of the cover;
  • Figure 2 is a section according to Figure 1 after destruction of the cover;
  • Figure 3 is a bottom view of the capsule according to Figures 1 and 2;
  • Figures 4a and 4b are schematic views taken from inside the container, showing, one the seal intact and the other the seal torn after screwing the capsule fully onto the neck of the container.

Selon les figures 1 et 2, un récipient 1 comporte un col 2 muni d'un filetage extérieur 3 et, en dessous de ce dernier, d'un bourrelet extérieur d'accrochage 4, le col se raccordant au récipient 1 par un épaulement 5 formant surface d'appui.According to Figures 1 and 2, a container 1 has a neck 2 provided with an external thread 3 and, below the latter, with an external hanging bead 4, the neck is connecting to the container 1 by a shoulder 5 forming a bearing surface.

Le col 2 est obturé à son extrémité supérieure par un opercule 6 perforable constitué par exemple par une membrane composée de façon connue d'une feuille d'aluminium doublée d'une feuille de manière plastique.The neck 2 is closed at its upper end by a perforable cover 6 constituted for example by a membrane composed in a known manner of aluminum foil lined with a plastic sheet.

Une capsule 7 moulée d'une seule pièce en matière plastique, par exemple en polypropylène, est rapportée sur le col 2 en vue du bouchage du récipient. La capsule 7 comprend un corps de capsule 8, une bague d'inviolabilité 9 et un couvercle à charnière 10.A capsule 7 molded in a single piece of plastic material, for example in polypropylene, is attached to the neck 2 for plugging the container. Capsule 7 includes a capsule body 8, a tamper-evident ring 9 and a hinged cover 10.

Le corps de capsule 8 comprend une paroi d'extrémité circulaire 11 munie d'un orifice verseur 12 entouré par une cheminée verseuse 13 par exemple cylindrique qui fait saillie vers le haut sur la paroi d'extrémité 11.The capsule body 8 comprises a circular end wall 11 provided with an orifice pourer 12 surrounded by a pouring chimney 13 for example cylindrical which makes protruding upwards on the end wall 11.

Une jupe 14 essentiellement cylindrique fait saillie vers le bas sur la paroi d'extrémité 11 sur le bord de cette dernière, la jupe 14 présentant un filetage intérieur 15 adapté au filetage 3 du col du récipient 2.A substantially cylindrical skirt 14 projects downward from the end wall 11 on the edge of the latter, the skirt 14 having an internal thread 15 adapted to the thread 3 of container neck 2.

Selon un mode de réalisation illustré sur les figures, le corps de capsule 8 présente une symétrie de révolution par rapport à un axe R qui, lorsque la capsule 7 est rapportée sur le col 2, est sensiblement confondu avec l'axe principal de celui-ci.According to an embodiment illustrated in the figures, the capsule body 8 has a symmetry of revolution with respect to an axis R which, when the capsule 7 is attached to the neck 2, is substantially coincident with the main axis thereof.

L'axe R est confondu avec l'axe de rotation du corps de capsule 8 lors de son vissage sur le col 2 du récipient 1. The axis R coincides with the axis of rotation of the capsule body 8 when it is screwed on the neck 2 of the container 1.

La capsule 7 est décrite dans une position où l'axe R est vertical, et définit une direction d'élévation par rapport à laquelle sont définis les termes « haut », « bas », « supérieur », « inférieur ».The capsule 7 is described in a position where the axis R is vertical, and defines a direction elevation from which the terms "high", "low" are defined, " superior inferior ".

Une localisation à proximité de l'axe R est dite « intérieure », par opposition à une localisation à distance de l'axe R, dite « extérieure ».A location close to the R axis is said to be "interior", as opposed to a location at a distance from the R axis, known as “outside”.

Une dent 16 dont la conformation et la fonction seront décrites plus en détail ci-après, fait saillie vers le bas sur la paroi d'extrémité 11, en position excentrée.A tooth 16 whose conformation and function will be described in more detail below, protrudes downwards on the end wall 11, in the eccentric position.

A son extrémité inférieure, la jupe 14 se raccorde à une paroi extérieure 17 qui prolonge le corps de la capsule 8 vers le bas sous la forme d'une paroi sensiblement cylindrique, et à une paroi extérieure 18 qui s'étend vers le haut, en entourant la jupe 14 à distance, sous la forme d'une paroi de forme générale tronconique divergente, sensiblement jusqu'au niveau de la paroi d'extrémité 11 du corps de capsule 8.At its lower end, the skirt 14 is connected to an outer wall 17 which extends the body of the capsule 8 downwards in the form of a substantially cylindrical wall, and to an outer wall 18 which extends upwards, surrounding the skirt 14 at a distance, in the form of a wall of generally divergent frustoconical shape, substantially up to the level of the end wall 11 of the capsule body 8.

Le couvercle 10 est relié par une charnière horizontale 19 de type connu en soi à l'extrémité supérieure de la paroi extérieure 18. Le couvercle 10 comporte, sur sa face inférieure, une collerette annulaire 20 qui, en position fermée du couvercle 10, est emboítée sur la cheminée 13 de l'orifice verseur 12.The cover 10 is connected by a horizontal hinge 19 of a type known per se to the upper end of the outer wall 18. The cover 10 has, on its face lower, an annular flange 20 which, in the closed position of the cover 10, is fitted onto the chimney 13 of the pouring orifice 12.

La bague d'inviolabilité 9 se raccorde à l'extrémité inférieure de la paroi 17 par plusieurs ponts frangibles 21, et présente intérieurement des moyens d'encliquetage 22 constitués, comme le montre surtout la figure 3, par une rangée de saillies intérieures ayant un profil leur permettant de s'encliqueter de façon irréversible sous le bourrelet d'accrochage 4 du col 2 du récipient 1.The tamper-evident ring 9 is connected to the lower end of the wall 17 by several frangible bridges 21, and internally has latching means 22 constituted, as shown above in FIG. 3, by a row of internal projections having a profile allowing them to snap irreversibly under the bead attachment 4 of the neck 2 of the container 1.

La capsule peut prendre deux positions :

  • une position dite haute, représentée sur la figure 1, où, la bague d'inviolabilité 9 étant en appui sur l'épaulement 5, la paroi d'extrémité 11 est située à distance de l'ouverture du col 2, la jupe 14 étant partiellement vissée sur celui-ci ; et
  • une position dite basse, représentée sur la figure 2, où, la bague d'inviolabilité ayant été arrachée, la jupe 14 est vissée à fond sur le col 2 de sorte que la paroi d'extrémité 11 soit sensiblement en contact avec le col 2 et l'opercule 6.
The capsule can take two positions:
  • a so-called high position, shown in Figure 1, where, the tamper-evident ring 9 rests on the shoulder 5, the end wall 11 is located at a distance from the opening of the neck 2, the skirt 14 being partially screwed onto it; and
  • a so-called low position, shown in Figure 2, where, the tamper-evident ring having been torn off, the skirt 14 is screwed fully onto the neck 2 so that the end wall 11 is substantially in contact with the neck 2 and cover 6.

Selon un mode de réalisation, la dent 16 en saillie sur la paroi d'extrémité 11 du corps de capsule 8 présente une hauteur h16 qui est inférieure au pas p des filetages 3 et 15 du col 2 et de la jupe 14.According to one embodiment, the tooth 16 projecting from the end wall 11 of the body of cap 8 has a height h16 which is less than the pitch p of threads 3 and 15 collar 2 and skirt 14.

La bague de garantie 9 présente de son côté une hauteur h9 qui est supérieure à la hauteur h16 de la dent 16.The guarantee ring 9 has for its part a height h9 which is greater than the height h16 of tooth 16.

De la sorte, lorsque la capsule 7 est en position haute, la dent 16 n'est pas en contact avec l'opercule 6, celui-ci assurant l'étanchéité et l'inviolabilité du récipient 1.In this way, when the capsule 7 is in the high position, the tooth 16 is not in contact with the cover 6, this ensuring the tightness and the inviolability of the container 1.

Enfin, la hauteur h2 du col 2, entre la surface d'appui 5 et l'extrémité supérieure du col, obturée par l'opercule 6, est au moins égale à la hauteur h8 que le corps de capsule 8 présente intérieurement, entre la paroi d'extrémité 11 et l'extrémité inférieure de la paroi extérieure 17.Finally, the height h2 of the neck 2, between the bearing surface 5 and the upper end of the neck, closed by the cover 6, is at least equal to the height h8 that the capsule body 8 internally, between the end wall 11 and the lower end of the wall outdoor 17.

Tel que le montre surtout la figure 3, qui fait également apparaítre la patte de préhension 23 permettant l'arrachage de la bague de garantie 9, l'orifice verseur 12 est situé en position excentrée sur la paroi d'extrémité 11 de sorte que, la cheminée 13 étant par exemple cylindrique d'axe R1 sensiblement parallèle à l'axe R du corps 8, l'axe R1 est écarté de l'axe R.As shown above especially in Figure 3, which also shows the tab of gripping 23 allowing the tear-off of the guarantee ring 9, the pouring orifice 12 is located in an eccentric position on the end wall 11 so that the chimney 13 being for example cylindrical with an axis R1 substantially parallel to the axis R of the body 8, the axis R1 is moved away from the axis R.

Par ailleurs, la dent 17, en saillie vers le bas sur la paroi d'extrémité 11, est distincte de l'orifice verseur 12 et de la cheminée 13, en étant située à distance de l'orifice 12.Furthermore, the tooth 17, projecting downwards on the end wall 11, is distinct from the pouring orifice 12 and the chimney 13, being located at a distance from the orifice 12.

La dent 16 est située à distance de l'axe R. On note e16 la distance maximale séparant la dent 16 de l'axe R, et e12 la distance maximale séparant le bord de l'orifice verseur 21 de l'axe R. Tooth 16 is located at a distance from the axis R. We denote by e16 the maximum distance separating the tooth 16 of the axis R, and e12 the maximum distance separating the edge of the pouring orifice 21 of axis R.

La distance séparant l'axe de rotation R de la dent 16 est supérieure à la distance séparant l'axe de rotation R de l'orifice verseur 12, de sorte que la distance e16 est supérieure à la distance e12 (figure 3).The distance between the axis of rotation R of the tooth 16 is greater than the distance separating the axis of rotation R from the pouring orifice 12, so that the distance e16 is greater than the distance e12 (figure 3).

Selon un mode de réalisation, illustré sur les figures, la dent 16 comprend une paroi 24 incurvée qui se présente sous la forme d'une portion de cylindre d'axe parallèle à l'axe R, et qui présente une concavité tournée vers l'intérieur de la capsule 7.According to one embodiment, illustrated in the figures, the tooth 16 comprises a wall 24 curved which is in the form of a cylinder portion with an axis parallel to the axis R, and which has a concavity turned towards the inside of the capsule 7.

La paroi présente une face extérieure 25 destinée, lors du vissage de la capsule 7 sur le col 2, à appuyer sur l'opercule 6 en lui appliquant une force F orientée vers l'extérieur de la capsule 7, pour déchirer à force l'opercule 6.The wall has an outer face 25 intended, when the capsule 7 is screwed onto the neck 2, to press on the cover 6 by applying a force F oriented towards the outside of the capsule 7, to forcefully tear the lid 6.

En outre, la dent 16 peut comprendre un tenon 26 saillant de la paroi 24 vers l'intérieur de la capsule 7 par une face intérieure 27 opposée à la face extérieure 25, de sorte que la dent 16 présente un profil en T dans un plan de coupe horizontal.In addition, the tooth 16 may comprise a tenon 26 projecting from the wall 24 inwards of the capsule 7 by an inner face 27 opposite the outer face 25, so that tooth 16 has a T-profile in a horizontal cutting plane.

Ce tenon 27 forme moyen de renfort de la paroi 24 lorsque la face extérieure est en appui sur l'opercule 6 et que la paroi est soumise à la force de réaction de l'opercule, dirigée vers l'intérieur de la capsule 7.This stud 27 forms a means of reinforcing the wall 24 when the outer face is in pressing on the cover 6 and that the wall is subjected to the reaction force of the cover, directed towards the inside of the capsule 7.

Par ailleurs, selon un mode de réalisation illustré sur les figures 1 et 2, la dent 16 est biseautée pour former une pointe 28 destinée à faciliter la perforation de l'opercule préalablement à son déchirement lors du vissage de la capsule 7 sur le col 2 du récipient 1.Furthermore, according to an embodiment illustrated in Figures 1 and 2, the tooth 16 is bevelled to form a point 28 intended to facilitate the perforation of the cover prior to its tearing during the screwing of the capsule 7 on the neck 2 of the container 1.

L'orifice verseur 12 et la dent 16 sont par exemple excentrés vers le même côté, de telle manière que leurs bords situés en avant dans le sens de vissage (flèche V) de la capsule 7 sur le col 2 se trouvent sensiblement sur un même rayon (figure 3).The pouring orifice 12 and the tooth 16 are for example eccentric to the same side, of so that their edges located forward in the direction of screwing (arrow V) of the capsule 7 on the neck 2 are substantially on the same radius (Figure 3).

Lors du vissage de la capsule 7 complète comprenant le corps de capsule 8, la bague de garantie 9 et le couvercle 10 sur le col de récipient 2, la bague de garantie 9 vient s'encliqueter, par des saillies intérieures 22, sous le bourrelet d'accrochage 4 du col 2 avant de porter par son extrémité inférieure contre la surface d'appui 5 de l'épaulement du récipient 1.When screwing the complete capsule 7 comprising the capsule body 8, the ring guarantee 9 and the cover 10 on the container neck 2, the guarantee ring 9 comes snap into place, by internal projections 22, under the attachment bead 4 of the neck 2 before carrying by its lower end against the bearing surface 5 of the shoulder from container 1.

Compte tenu du profil des saillies 22 et du bourrelet, cet encliquetage est définitif, c'est-à-dire qu'un dévissage ultérieur de la capsule 7 ne permet pas de dégager la bague de garantie 9 d'en dessous la collerette 4, mais provoque au contraire irrémédiablement une rupture des ponts frangibles 21 reliant la bague 9 à la paroi 17 du corps de capsule 8.Given the profile of the projections 22 and the bead, this snap-fastening is final, that is to say that a subsequent unscrewing of the capsule 7 does not allow the ring to be released guarantee 9 from below the collar 4, but on the contrary causes irreparably a break in the frangible bridges 21 connecting the ring 9 to the wall 17 of the capsule body 8.

Dans la position visible sur la figure 1 dans laquelle la capsule 7 complète est vissée sur le col, la bague 9 étant encliquetée sous le bourrelet 4 et en appui sur la surface d'appui 5, la dent 16 se trouve maintenue à distance au-dessus de l'opercule 6 du col 2, laissant ainsi cet opercule 6 intact.In the position visible in Figure 1 in which the complete capsule 7 is screwed on the neck, the ring 9 being snapped under the bead 4 and resting on the surface support 5, the tooth 16 is kept at a distance above the cover 6 of the neck 2, thus leaving this cover 6 intact.

C'est dans cette position de la capsule 7 sur le col 2 que le produit conditionné dans le récipient 1 est commercialisé, l'acheteur ayant ainsi la garantie que l'opercule 6 est intact.It is in this position of the capsule 7 on the neck 2 that the product packaged in the container 1 is sold, the buyer thus having the guarantee that the seal 6 is intact.

A la première utilisation, l'acheteur arrache la bague de garantie 9 par action sur la patte de préhension 23. Une fois la bague de garantie arrachée, il visse à fond la partie restante de la capsule 7, comprenant le corps 8 et le couvercle 10.At first use, the buyer tears off the warranty ring 9 per action on the gripping tab 23. Once the warranty ring is torn off, it screws the part fully remaining of the capsule 7, comprising the body 8 and the cover 10.

Au cours de ce vissage à fond, la pointe 28 entre en contact avec l'opercule 6, de sorte que dans un premier temps la dent 16 perfore l'opercule 6.During this thorough screwing, the tip 28 comes into contact with the cover 6, so that initially the tooth 16 pierces the cover 6.

Dans un deuxième temps, la face extérieure 25 de la dent 16 pousse l'opercule 6 en lui appliquant une force F qui provoque son déchirement, la dent 16 repoussant devant elle la partie déchirée de l'opercule 6 qui, en fin de vissage, reste attaché au col 2, aucune partie de l'opercule 6 ne tombant dans le récipient 1.Secondly, the outer face 25 of the tooth 16 pushes the cover 6 in it applying a force F which causes it to tear, tooth 16 pushing back in front of it the torn part of the cover 6 which, at the end of screwing, remains attached to the neck 2, no part of the cover 6 does not fall into the container 1.

Ce déchirement de l'opercule 6 est à distinguer d'une simple découpe, telle que décrite notamment dans les documents cités dans la partie introductive de la présente demande. This tearing of the cover 6 is to be distinguished from a simple cut, as described in particular in the documents cited in the introductory part of this request.

Au cours du vissage, la dent 16 décrit une trajectoire C en forme d'arc de cercle d'axe R, dont on note T la direction de la tangente au niveau de la dent 16.During screwing, tooth 16 describes a trajectory C in the form of an arc of an axis circle R, of which we note T the direction of the tangent at the level of tooth 16.

La dent 16 est orientée pour que sa face extérieure 24 ne soit pas tangente à la trajectoire C mais soit inclinée par rapport à celle-ci, de sorte que la direction de la force F forme un angle α non nul avec la direction de la tangente T à la trajectoire C.The tooth 16 is oriented so that its outer face 24 is not tangent to the trajectory C but is inclined with respect to it, so that the direction of the force F forms a non-zero angle α with the direction of the tangent T to the path C.

En poussant l'opercule 6, la dent 16, qui présente une dimension axiale suffisante, force celui-ci à se plier vers le bas, pour dégager une ouverture 29 en forme de croissant ou de lunule.By pushing the cover 6, the tooth 16, which has a sufficient axial dimension, forces the latter to bend downwards, to release a crescent-shaped opening 29 or of lunula.

Cette ouverture 29 englobe, selon un plan horizontal, l'orifice verseur 12 pour permettre une communication sans obstacle entre le produit contenu dans le récipient 1 et l'orifice verseur 12, et assurer une sortie directe du produit par l'orifice verseur 12 (figure 4b).This opening 29 includes, in a horizontal plane, the pouring orifice 12 to allow barrier-free communication between the product in container 1 and the orifice pourer 12, and ensure a direct outlet of the product through the pouring orifice 12 (Figure 4b).

Après ouverture du couvercle, par pivotement autour de la charnière 19, l'utilisateur peut alors distribuer le produit à travers l'orifice 12 (et la cheminée 13) sans que la distribution ne soit en aucune manière gênée ou perturbée par l'opercule 6.After opening the cover, by pivoting around the hinge 19, the user can then distribute the product through the orifice 12 (and the chimney 13) without the distribution is in no way hindered or disturbed by the seal 6.

A la fin de la distribution, le rabattement du couvercle 10 autour de la charnière 19 sur le corps de capsule 8 permet d'obturer la cheminée 13.At the end of the distribution, the folding of the cover 10 around the hinge 19 on the capsule body 8 makes it possible to close off the chimney 13.

La dent 16 pourrait, dans le cadre de l'invention, présenter un profil différent, à condition que ce profil assure un déchirage de l'opercule plutôt qu'un découpage ou tranchage, et en particulier permette à la dent de repousser devant elle la partie déchirée de l'opercule.Tooth 16 could, in the context of the invention, have a different profile, provided that this profile ensures a tearing of the lid rather than a cutting or slicing, and in particular allows the tooth to push back in front of it the torn part of the cap.

L'orifice verseur 12 pourrait également se trouver en position centrale, ou dans une position excentrée différente de celle représentée, bien que la disposition réciproque illustrée de l'orifice verseur et de la dent procure un dégagement optimal de l'orifice verseur par l'opercule moyennant un angle de dévissage réduit de la capsule, après arrachement de la bande de garantie. The pouring orifice 12 could also be in the central position, or in a offset position different from that shown, although the reciprocal arrangement illustrated with the pouring orifice and the tooth provides optimum clearance from the orifice pourer through the lid by means of a reduced unscrewing angle of the capsule, after tearing off the guarantee strip.

La capsule peut être utilisée en particulier dans le domaine alimentaire, par exemple pour des sauces, des condiments, etc.The capsule can be used in particular in the food sector, for example for sauces, condiments, etc.
