Description

RÉCIPIENT, NOTAMMENT À USAGE ALIMENTAIRE  CONTAINER, IN PARTICULAR FOR FOOD USE
La présente invention concerne un récipient, notamment à usage alimentaire. The present invention relates to a container, particularly for food use.
Il est connu, notamment par le document FR 2 922 195 au nom du même déposant, de réaliser un récipient comprenant un manchon d'obturation/libération de l'ouverture du récipient. Ce manchon, relié au corps du récipient et à une bague mobile en pivotement par rapport à ce corps, est en une matière souple et élastique, et peut être déformé par vrillage entre un état de vrillage, dans lequel il obture l'ouverture du récipient, et un état de non vrillage, dans lequel il libère cette ouverture. It is known, in particular from document FR 2 922 195 in the name of the same applicant, to make a container comprising a closure sleeve / release of the opening of the container. This sleeve, connected to the body of the container and to a pivotally movable ring relative to this body, is made of a flexible and elastic material, and can be deformed by twisting between a twisting state, in which it closes the opening of the container. , and a state of non-twisting, in which it releases this opening.
Les récipients existants ne donnent pas parfaitement satisfaction en ce qui concerne leur manipulation ou les possibilités qu'ils offrent d'obturation/libération de ladite ouverture.  The existing containers do not give complete satisfaction with regard to their handling or the possibilities they offer for closing / releasing said opening.
De plus, les récipients existants ont pour inconvénient notable, lorsque le produit contenu dans le récipient a été versé depuis ce récipient, qu'un reste de produit soit présent sur la face extérieure de la membrane formée par le manchon à l'état de vrillage de ce dernier.  In addition, the existing containers have the significant disadvantage, when the product contained in the container has been poured from this container, a remainder of product is present on the outer face of the membrane formed by the sleeve in the state of twisting of the last.
Le document N° US 2005/082248 A1 illustre un autre récipient connu, du même type à manchon vrillable, et comprenant des crans d'immobilisation de la bague dans une position angulaire donnée.  Document No. US 2005/082248 A1 illustrates another known container, of the same type with a screwable sleeve, and comprising notches for immobilizing the ring in a given angular position.
La présente invention a pour objectif de remédier à l'ensemble des inconvénients précités.  The present invention aims to remedy all of the aforementioned drawbacks.

- l'autre parmi ladite paroi périphérique et ladite bague comprend un ergot apte à être engagé et à coulisser dans ladite rainure oblique et dans ladite rainure circonférentielle, et apte à venir s'engager partiellement dans l'une ou l'autre desdites encoches de ladite pluralité d'encoches,  the other of said peripheral wall and said ring comprises a pin able to be engaged and to slide in said oblique groove and in said circumferential groove, and able to engage partially in one or the other of said notches of said plurality of notches,
ladite rainure oblique étant disposée de telle sorte que le déplacement dudit ergot en elle réalise un déplacement axial de la bague dans le sens du rapprochement axial de la bague et de ladite ouverture au cours d'une première partie du mouvement de la bague depuis ladite position de libération vers ladite position d'obturation, et, inversement, de telle sorte que ce déplacement réalise un déplacement axial de la bague dans le sens de l'éloignement axial de la bague et de ladite ouverture au cours d'une deuxième partie du mouvement de la bague depuis ladite position d'obturation vers ladite position de libération, said oblique groove being arranged in such a way that the displacement of said pin in it causes an axial displacement of the ring in the direction of the axial approximation of the ring and of said opening during a first part of the movement of the ring from said position releasing to said closed position, and, conversely, such that this displacement effects an axial displacement of the ring in the direction of the axial distance of the ring and said opening during a second part of the movement the ring from said shutter position to said release position,
au moins une première desdites encoches étant positionnée angulairement de manière à recevoir ledit ergot lorsque le manchon est dans un état de vrillage partiel, et une deuxième desdites encoches étant positionnée angulairement de manière à recevoir ledit ergot lorsque le manchon est dans un état de complet vrillage. at least one of said notches being positioned angularly so as to receive said pin when the sleeve is in a partial twisting state, and a second of said notches being angularly positioned to receive said pin when the sleeve is in a state of complete twisting .
L'invention consiste ainsi à prévoir une mobilité guidée de la bague par rapport à ladite paroi périphérique, réalisée par le guidage dudit ergot dans lesdites rainures puis dans l'une ou l'autre desdites encoches.  The invention thus consists in providing guided mobility of the ring relative to said peripheral wall, carried out by guiding said pin in said grooves and then in one or the other of said notches.
Dans ladite position de libération, la bague est dans une position axiale d'éloignement par rapport à ladite ouverture et le manchon forme une première partie s'étendant le long de la face intérieure de ladite paroi périphérique, une partie intermédiaire enveloppant ledit bord libre, et une deuxième partie s'étendant le long de la face extérieure de la paroi périphérique, cette deuxième partie étant reliée à la bague. Dans cette position de libération, lorsque du produit contenu dans le récipient est versé en dehors du récipient, ce produit s'écoule le long de ladite première partie et de ladite partie intermédiaire du manchon, mais pas sur ladite deuxième partie de ce manchon. In said release position, the ring is in an axial position away from said opening and the sleeve forms a first portion extending along the inner face of said peripheral wall, a portion intermediate wrapping said free edge, and a second portion extending along the outer face of the peripheral wall, the second portion being connected to the ring. In this release position, when the product contained in the container is poured out of the container, this product flows along said first portion and said intermediate portion of the sleeve, but not on said second portion of this sleeve.
Le mouvement de la bague vers ladite position d'obturation à partir de cette position de libération réalise un déplacement de l'ergot dans ladite rainure oblique, qui réalise le déplacement axial précité de la bague en rapprochement de l'ouverture, en même temps que s'initie le vrillage du manchon. Ce déplacement axial réalise une rétractation de ladite première partie et de ladite partie intermédiaire du manchon vers l'intérieur du corps de récipient, de telle sorte qu'un reste de produit présent sur cette première partie et cette partie intermédiaire se trouve en-deçà de la zone du manchon destinée à être vrillée lors de l'obturation. Le déplacement subséquent de l'ergot dans ladite rainure circonférentielle réalise ensuite un déplacement guidé de la bague en pivotement par rapport à la paroi périphérique, qui poursuit le vrillage du manchon. Ensuite, l'engagement de l'ergot dans l'une ou l'autre des encoches précitées, et le maintien de cet ergot dans cette encoche, réalisé par l'effet de rappel élastique axial qu'exerce le manchon vrillé sur la bague, permet de maintenir la bague dans la position angulaire choisie, d'obturation partielle ou totale du récipient.  The movement of the ring towards said closed position from this release position makes a displacement of the lug in said oblique groove, which makes the aforementioned axial displacement of the ring towards the opening, at the same time as initiates twisting of the sleeve. This axial displacement effects a retraction of said first part and of said intermediate portion of the sleeve towards the inside of the container body, so that a remainder of product present on this first part and this intermediate part is below the zone of the sleeve intended to be twisted during sealing. The subsequent displacement of the lug in said circumferential groove then realizes a guided displacement of the ring pivotally relative to the peripheral wall, which continues the twisting of the sleeve. Then, the engagement of the lug in one or the other of the aforementioned notches, and the maintenance of this lug in this notch, achieved by the axial elastic return effect exerted by the twisted sleeve on the ring, keeps the ring in the selected angular position, partial or total closure of the container.
Après obturation, le reste de produit précité se trouve sur la face interne de la membrane que forme ce manchon vrillé, et aucune présence de produit n'existe sur la face externe de cette membrane.  After sealing, the remainder of the aforementioned product is on the inner face of the membrane formed by this twisted sleeve, and no product presence exists on the outer face of this membrane.
Le mouvement de libération de l'ouverture du récipient à partir de ladite position d'obturation se réalise selon une séquence inverse de celle détaillée ci-dessus.  The release movement of the opening of the container from said closed position is performed in a sequence opposite to that detailed above.
Le récipient pourrait comprendre uniquement un ergot et un unique ensemble de rainures telles que précitées ; de préférence, toutefois, le récipient comprend deux ergots angulairement opposés et deux ensembles de rainures, angulairement opposés de manière correspondante.  The container could comprise only a lug and a single set of grooves as mentioned above; preferably, however, the container comprises two angularly opposed lugs and two sets of grooves, angularly correspondingly opposed.
Un parfait guidage de la bague est ainsi obtenu.  A perfect guiding of the ring is thus obtained.
Le corps de récipient pourrait alors comprendre soit les deux ergots, soit les deux ensembles de rainures, et la bague pourrait comprendre respectivement soit les deux ensembles de rainures soit les deux ergots ; de préférence, toutefois, pour l'obtention d'un faible encombrement, le corps de récipient comprend un premier ergot et un premier ensemble de rainures telles que précitées tandis que la bague comprend un deuxième ensemble de rainures, destiné à recevoir ledit premier ergot, ainsi qu'un deuxième ergot destiné à être engagé dans ledit premier ensemble de rainures. The container body could then comprise either the two lugs or the two sets of grooves, and the ring could respectively comprise either the two sets of grooves or the two lugs; preferably, however, to obtain a small footprint, the container body comprises a first and a first set of grooves as aforesaid while the ring comprises a second set of grooves for receiving said first lug, and a second lug to be engaged in said first set of grooves.
De préférence, la bague présente une hauteur (c'est-à-dire une dimension dans le sens axial) qui est moindre que la hauteur de ladite paroi périphérique ; ledit deuxième ensemble de rainures ne comprend alors pas de rainure circonférentielle mais uniquement une rainure oblique, et ledit premier ergot s'échappe dudit deuxième ensemble de rainures en fin du mouvement de rapprochement axial de la bague et de ladite ouverture. La bague est guidée en pivotement uniquement par le déplacement du deuxième ergot dans ladite rainure circonférentielle, ce qui n'est pas particulièrement gênant en pratique.  Preferably, the ring has a height (i.e., a dimension in the axial direction) which is less than the height of said peripheral wall; said second set of grooves then does not comprise a circumferential groove but only an oblique groove, and said first lug escapes from said second set of grooves at the end of the movement of axial approximation of the ring and of said opening. The ring is pivotally guided only by the displacement of the second lug in said circumferential groove, which is not particularly inconvenient in practice.
De préférence, la rainure circonférentielle comprend au moins deux encoches positionnées angulairement de manière à recevoir ledit ergot lorsque le manchon est dans un état de vrillage partiel, à savoir :  Preferably, the circumferential groove comprises at least two slots positioned angularly so as to receive said lug when the sleeve is in a partial twisting state, namely:
- une encoche positionnée sensiblement aux environs d'une mi-obturation de l'ouverture du récipient, laissant subsister une ouverture suffisante pour permettre la cuisson d'un produit contenu dans le récipient, par exemple dans un four à microondes, cette position étant dite, pour cette raison, "position cuisson" ;  a notch positioned substantially around a half-closing of the opening of the container, leaving a sufficient opening to allow the cooking of a product contained in the container, for example in a microwave oven, this position being said for this reason, "cooking position";
- au moins une encoche positionnée du côté de l'encoche correspondant à la position de complète obturation de l'ouverture, permettant de laisser subsister une ouverture juste suffisante pour le passage d'une paille de boisson, cette position étant dite, pour cette raison, position "paille".  at least one notch positioned on the side of the notch corresponding to the position of complete closure of the opening, allowing to leave an opening just sufficient for the passage of a drinking straw, this position being said, for this reason , position "straw".
De préférence, chaque ensemble de rainures comprend une entrée, débouchant au niveau du bord libre de la paroi périphérique ou d'un bord libre de la bague, communiquant avec ladite première extrémité de ladite rainure oblique.  Preferably, each set of grooves comprises an inlet, opening at the free edge of the peripheral wall or a free edge of the ring, communicating with said first end of said oblique groove.
Cette entrée facilite l'engagement de l'ergot dans ledit ensemble de rainures. This input facilitates the engagement of the lug in said set of grooves.
Pour éviter, lors de l'utilisation du récipient, un engagement intempestif de l'ergot dans ladite entrée, et donc pour maintenir l'ergot dans ledit ensemble de rainures, chaque ensemble de rainures comprend une marche, ou autre type de point dur, entre ladite rainure oblique et ladite entrée, devant être franchie par l'ergot pour passer de ladite rainure oblique à ladite entrée. To avoid, during the use of the container, inadvertent engagement of the lug in said inlet, and thus to maintain the lug in said set of grooves, each set of grooves comprises a step, or other type of hard point, between said oblique groove and said inlet, to be crossed by the lug to move from said oblique groove to said inlet.
De préférence, ladite entrée présente une largeur allant en augmentant en direction dudit bord libre. Les parois formant les bords latéraux de cette rainure permettent de guider le retour de l'ergot dans ladite rainure oblique et facilitent par conséquent ce retour. Preferably, said inlet has a widening width towards said free edge. The walls forming the lateral edges of this groove guide the return of the lug in said oblique groove and thus facilitate this return.
De préférence, chaque ensemble de rainures comprend en outre :  Preferably, each set of grooves further comprises:
une rainure intermédiaire, située entre ladite rainure oblique et ladite entrée, communiquant avec chacune de ces dernières ; et  an intermediate groove, located between said oblique groove and said inlet, communicating with each of the latter; and
une rainure de désengagement de la bague, communiquant avec cette rainure intermédiaire et qui débouche dans ledit bord libre.  a groove of disengagement of the ring, communicating with this intermediate groove and which opens into said free edge.
L'engagement de l'ergot dans cette rainure de désengagement permet un déplacement de la bague en pivotement au-delà de ladite position d'ouverture, avec vrillage du manchon, et un déplacement axial de cette bague le long de ladite paroi périphérique, jusqu'au-delà de l'ouverture du récipient. Ce déplacement permet de dégager la bague par rapport à ladite paroi en allongeant le manchon, et donc de réaliser un nettoyage facilité du récipient ; la position dégagée de la bague est dite, pour cette raison, "position nettoyage".  The engagement of the lug in this disengagement groove allows a displacement of the ring pivoting beyond said open position, with twisting of the sleeve, and an axial displacement of the ring along said peripheral wall, until beyond the opening of the container. This displacement makes it possible to disengage the ring with respect to said wall by lengthening the sleeve, and thus to achieve a facilitated cleaning of the container; the unobstructed position of the ring is said, for this reason, "cleaning position".
Pour éviter, lors de l'utilisation du récipient, un engagement intempestif de l'ergot dans ladite rainure de désengagement, ladite rainure intermédiaire communique avec cette rainure de désengagement par une marche, ou autre type de point dur, devant être franchie par l'ergot pour passer de ladite rainure intermédiaire à ladite rainure de désengagement.  To avoid, during the use of the container, inadvertent engagement of the lug in said disengagement groove, said intermediate groove communicates with this disengagement groove by a step, or other type of hard point, to be crossed by the pin to move from said intermediate groove to said disengagement groove.
P o u r fa c i l i te r ce n ettoya g e , l a d i te p a ro i p é ri p h é ri q u e co m p rend avantageusement de larges ouvertu res donnant accès à la face externe du manchon.  For example, the preferred method is to provide large openings that provide access to the outer face of the sleeve.
L'invention sera bien comprise, et d'autres caractéristiques et avantages de celle-ci apparaîtront, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif, deux formes de réalisation possibles du récipient concerné.  The invention will be better understood, and other features and advantages thereof will become apparent with reference to the attached schematic drawing showing, by way of non-limiting example, two possible embodiments of the container concerned.

la figure 28 est une vue en coupe, similaire à la figure 23, d'une bague externe que comprend le récipient. La figure 1 représente un récipient 1 notamment à usage alimentaire, comprenant un corps de récipient 2 formant une ouverture supérieure 2a, un manchon 3 en matière souple et élastique et une bague 4 mobile en pivotement et axialement par rapport à ce corps 2, ledit manchon 3 étant relié au corps 2 d'une part et à la bague 4 d'autre part. Comme le montrent les figures 3 à 18, le manchon 3 est apte à être vrillé par pivotement de la bague 4 par rapport au corps 2, cette déformation se faisant en entre un état de non vrillage (cf. figures 3 à 6), dans lequel le manchon 3 libère complètement l'ouverture 2a, et un état de complet vrillage (cf. figures 15 à 18), dans lequel ce manchon 3 obture complètement cette ouverture 2a. Figure 28 is a sectional view, similar to Figure 23, of an outer ring that includes the container. FIG. 1 represents a container 1, particularly for food use, comprising a container body 2 forming an upper opening 2a, a sleeve 3 made of flexible and elastic material and a ring 4 that is pivotally movable and axially with respect to this body 2, said sleeve 3 being connected to the body 2 on the one hand and the ring 4 on the other. As shown in Figures 3 to 18, the sleeve 3 is adapted to be twisted by pivoting of the ring 4 relative to the body 2, this deformation being in between a non-twist condition (see Figures 3 to 6), in which the sleeve 3 completely releases the opening 2a, and a state of complete twisting (see Figures 15 to 18), wherein the sleeve 3 completely closes the opening 2a.
La bague 4 peut également être placée et maintenue dans une position intermédiaire d'obturation dite "position cuisson" (cf. figures 7 à 10) et dans une position intermédiaire d'obturation dite "position paille" (cf. figures 1 1 à 14).  The ring 4 can also be placed and held in an intermediate position of closure called "cooking position" (see FIGS. 7 to 10) and in an intermediate position of closure called "straw position" (see FIGS. ).
La bague 4 peut en outre être placée dans une position surélevée de dégagement, dite "position nettoyage" (cf. figures 19 à 22).  The ring 4 can also be placed in a raised release position, called the "cleaning position" (see FIGS.
Comme le montrent plus particulièrement les figures 2 et 6, le récipient 1 est, dans l'exemple représenté, formé par l'assemblage d'un gobelet interne et d'un gobelet externe, de sorte qu'il est à double parois. Les bords libres supérieurs de ces gobelets interne et externe forment conjointement un siège de réception d'une paroi périphérique circulaire 10, se terminant par un bord libre qui délimite l'ouverture 2a.  As shown more particularly in Figures 2 and 6, the container 1 is, in the example shown, formed by the assembly of an inner cup and an outer cup, so that it is double-walled. The upper free edges of these inner and outer cups together form a seat for receiving a circular peripheral wall 10, ending in a free edge which defines the opening 2a.
Cette paroi 10 comprend un ensemble de rainures aménagées en creux dans sa paroi, depuis sa face externe, s'étendant de la droite vers la gauche sur la figure 2, cet ensemble étant formé par une entrée 13, une rainure intermédiaire 12, une rainure de désengagement 17, 11 une rainure oblique 14, une rainure circonférentielle 15, et une pluralité d'encoches 16 aménagées le long de ladite rainure circonférentielle 15.  This wall 10 comprises a set of grooves made hollow in its wall, from its external face, extending from the right to the left in FIG. 2, this assembly being formed by an inlet 13, an intermediate groove 12, a groove 17, 11 an oblique groove 14, a circumferential groove 15, and a plurality of notches 16 provided along said circumferential groove 15.
Cet ensemble est visible en développé sur la figure 5.  This set is visible in developed in Figure 5.
L'entrée 13 débouche dans le bord libre supérieur de la paroi 10 et communique avec la rainure intermédiaire 12 en un emplacement axialement distant de ce bord libre. El le présente une forme allant en s'évasant depuis sa communication avec la rainure 12 et en direction de ce bord libre. Comme cela est visible sur la figure 2, il existe en outre une différence de niveau entre le fond de l'entrée 13 et le fond, plus profond, de la rainure 12, formant une marche.  The inlet 13 opens into the upper free edge of the wall 10 and communicates with the intermediate groove 12 at a location axially distant from this free edge. It has a shape flaring from its communication with the groove 12 and towards this free edge. As can be seen in FIG. 2, there is also a difference in level between the bottom of the inlet 13 and the deeper bottom of the groove 12, forming a step.
La rainure intermédiaire 12 communique avec la rainure de désengagement 17, 1 1 , laquelle comprend une rainure oblique 17 communiquant avec la rainure intermédiaire 12 en un emplacement éloigné dudit bord libre, et une rainure axiale 1 1 débouche dans ce bord libre. Une différence de niveau existe entre le fond de la rainure 17 et le fond, plus profond, de la rainure 12, formant ainsi une marche. The intermediate groove 12 communicates with the disengagement groove 17, 1 1, which comprises an oblique groove 17 communicating with the groove intermediate 12 at a location remote from said free edge, and an axial groove 1 1 opens into this free edge. A difference in level exists between the bottom of the groove 17 and the bottom, deeper, of the groove 12, thus forming a step.
La rainure 12 communique également avec la rainure oblique 14, sur son côté longitudinal opposé à la rainure 17.  The groove 12 also communicates with the oblique groove 14, on its longitudinal side opposite the groove 17.
La rainure oblique 14 communique par une première extrémité avec la rainure 12, en un premier emplacement situé à une première distance axiale de ladite ouverture 2a. Elle communique par une deuxième extrémité avec la rainure circonférentielle 15, en un deuxième emplacement situé à une deuxième distance axiale de l'ouverture 2a, inférieure à ladite première distance axiale.  The oblique groove 14 communicates at a first end with the groove 12 at a first location at a first axial distance from said opening 2a. It communicates by a second end with the circumferential groove 15, at a second location located at a second axial distance from the opening 2a, less than said first axial distance.
La rainure circonférentielle 15 communique avec la rainure 14 et s'étend sur une large portion de la circonférence de la paroi 10.  The circumferential groove 15 communicates with the groove 14 and extends over a large portion of the circumference of the wall 10.
Les encoches 16 sont aménagées latéralement par rapport à la rainure 15, au niveau du flanc de cette dernière le plus proche dudit bord libre, et communiquent avec celle-ci. Comme le montre la figure 9, l'encoche 16 la plus proche de la rainure oblique 14 reçoit un ergot 21 solidaire de la bague 4 dans ladite "position cuisson" et permet de caler cette bague 4 dans cette position. Comme le montre la figure 13, une encoche 16 faisant partie d'une série de quatre encoches intermédiaires reçoit l'ergot 21 dans ladite "position paille" et permet de caler la bague 4 dans cette position, avec étanchéité de la membrane formée par le manchon 3 autour de cette paille ; quatre encoches intermédiaires 16 permettent d'obtenir plusieurs diamètres, adaptés à différents diamètres de paille. Comme le montre la figure 17, l'encoche 16 se trouvant à l'extrémité de la rainure 15 opposée à la rainure oblique 14 reçoit l'ergot 21 dans la position de complète obturation et permet de caler la bague 4 dans cette position.  The notches 16 are arranged laterally with respect to the groove 15, at the side of the latter closest to said free edge, and communicate therewith. As shown in Figure 9, the notch 16 closest to the oblique groove 14 receives a lug 21 integral with the ring 4 in said "cooking position" and allows to wedge this ring 4 in this position. As shown in Figure 13, a notch 16 forming part of a series of four intermediate notches receives the lug 21 in said "straw position" and allows to wedge the ring 4 in this position, with sealing of the membrane formed by the sleeve 3 around this straw; four intermediate notches 16 allow to obtain several diameters, adapted to different diameters of straw. As shown in Figure 17, the notch 16 at the end of the groove 15 opposite the oblique groove 14 receives the lug 21 in the position of complete closure and allows to wedge the ring 4 in this position.
Outre ledit ensemble en creux décrit ci-dessus, la paroi 10 comprend également un ergot 18, visible sur la figure 6, faisant saillie radialement vers l'extérieur de cette paroi 10 et situé diamétralement à l'opposé de l'entrée 13.  In addition to said recessed assembly described above, the wall 10 also comprises a lug 18, visible in Figure 6, projecting radially outwardly of the wall 10 and located diametrically opposite the inlet 13.
La paroi 10 comprend en outre un bord inférieur formant un siège de montage complémentaire de celui formé par lesdits gobelets du corps 2, ainsi que de larges ouvertures de nettoyage, qui la traversent.  The wall 10 further comprises a lower edge forming a mounting seat complementary to that formed by said cups of the body 2, as well as large cleaning openings, which pass through it.
Le manchon 3 est relié au corps 2 par emprisonnement de l'une de ses extrémités axiales entre le gobelet interne précité et la partie inférieure de la paroi 10, ainsi que cela apparaît sur la figure 6. Dans ladite position de libération de l'ouverture 2a montrée par cette figure 6, le manchon 3 présente une première partie s'étendant le long de la face intérieure de ladite paroi 10, une partie intermédiaire enveloppant le bord libre de cette paroi 10 et une deuxième partie s'étendant le long de la face extérieure de la paroi 10, cette deuxième partie étant reliée à la bague 4. The sleeve 3 is connected to the body 2 by imprisoning one of its axial ends between the aforementioned inner cup and the lower part of the wall 10, as shown in FIG. 6. In said release position of the opening 2a shown in this Figure 6, the sleeve 3 has a first portion extending along the inner face of said wall 10, an intermediate portion enveloping the free edge of the wall 10 and a second portion extending the along the outer face of the wall 10, this second part being connected to the ring 4.
La bague 4 présente une hauteur (c'est-à-dire une dimension dans le sens axial) qui est moindre que la hauteur de la paroi périphérique 10. Elle est formée par l'assemblage d'une bague interne 4a et d'une bague externe 4b emprisonnant entre elles la deuxième extrémité axiale du manchon 3.  The ring 4 has a height (that is to say a dimension in the axial direction) which is less than the height of the peripheral wall 10. It is formed by the assembly of an inner ring 4a and a external ring 4b trapping between them the second axial end of the sleeve 3.
Comme le montre les figures 2 et 23, la bague interne 4a comprend un ensemble 20 de rainures 12', 13', 14' et 17' aménagées en creux à partir de la face interne de cette bague interne ; ces rainures ont sensiblement la même structure que les rainures 12, 13, 14 et 17 précitées mais l'ensemble 20 est renversé par rapport à l'ensemble décrit plus haut, avec l'entrée 13' et la rainure de désengagement 17' de cet ensemble 20 débouchant dans le bord libre inférieur de la bague interne 4a. Les rainures 14' et 17' ont une longueur inférieure à celle des rainures 14 et 17 du fait de la hauteur moindre précitée de la bague 4 par rapport à la paroi 10, et l'ergot 18, qui se déplace dans cet ensemble 20 lors du déplacement axial de la bague 4, s'échappe de cet ensemble 20 en fin du mouvement de rapprochement axial de la bague 4 et de ladite ouverture 2a.  As shown in Figures 2 and 23, the inner ring 4a comprises an assembly 20 of grooves 12 ', 13', 14 'and 17' formed recessed from the inner face of the inner ring; these grooves have substantially the same structure as the grooves 12, 13, 14 and 17 above but the assembly 20 is reversed relative to the assembly described above, with the inlet 13 'and the disengagement groove 17' of this assembly 20 opening into the lower free edge of the inner ring 4a. The grooves 14 'and 17' have a length less than that of the grooves 14 and 17 because of the aforementioned lower height of the ring 4 relative to the wall 10, and the lug 18, which moves in this assembly 20 when axial displacement of the ring 4, escapes from this assembly 20 at the end of the movement of axial approximation of the ring 4 and said opening 2a.
Comme le montre la figure 2, l'entrée 13' d e cet e nse m b l e 20 est diamétralement opposée à l'entrée 13 de la paroi 10 dans ladite position de libération montrée par cette même figure 2, dans laquelle le manchon 3 n'est pas vrillé.  As shown in FIG. 2, the inlet 13 'of this mse e nse 20 is diametrically opposed to the inlet 13 of the wall 10 in said release position shown by this same FIG. 2, in which the sleeve 3 is not twisted.
La bague interne 4a comprend également un ergot 21 faisant saillie de sa face interne, radialement vers l'intérieur de cette bague 4a, cet ergot 21 étant situé de manière diamétralement opposée à l'entrée 13' que comprend ledit ensemble 20. Dans la position de libération montrée par la figure 6, cet ergot 21 est diamétralement opposé à l'ergot 18.  The inner ring 4a also comprises a lug 21 protruding from its inner face, radially inwardly of this ring 4a, this lug 21 being located diametrically opposite the inlet 13 'that comprises said assembly 20. In the position of release shown in Figure 6, this lug 21 is diametrically opposite the lug 18.
Comme cela se comprend en référence aux figures, le récipient 1 est assemblé en amenant les ergots 18 et 21 dans lesdites entrées 13, 13', puis par franchissement desdites marches et venue dans lesdites rainures intermédiaires 12, 12'. Le récipient 1 est alors dans la position de complète libération de l'ouverture 2a représentée sur les figures 3 à 6, dans laquelle la bague 4 est dans une position axiale reculée par rapport au bord libre de la paroi 10 et le manchon 3 forme ladite première partie, ladite partie intermédiaire et ladite deuxième partie. Dans cette position de libération, lorsque du produit contenu dans le récipient 1 est versé en dehors du récipient par l'ouverture 2a, ce produit s'écoule le long de ladite première partie et de ladite partie intermédiaire du manchon 3, mais pas sur ladite deuxième partie de ce manchon. As can be understood with reference to the figures, the container 1 is assembled by bringing the lugs 18 and 21 into said inlets 13, 13 ', then by crossing said steps and into said intermediate grooves 12, 12'. The container 1 is then in the position of complete release of the opening 2a shown in FIGS. 3 to 6, in which the ring 4 is in an axial position moved back relative to the free edge of the wall 10 and the sleeve 3 forms the said first part, said intermediate part and said second part. In this release position, when the product contained in the container 1 is poured out of the container through the opening 2a, this product flows along said first portion and said intermediate portion of the sleeve 3, but not on said second part of this sleeve.
Le mouvement d'obturation du récipient 1 à partir de ladite position de libération se réalise comme suit :  The shutter movement of the container 1 from said release position is as follows:
- déplacement des ergots 18 et 21 dans les rainures obliques 14, 14', réalisant tout d'abord un déplacement axial de la bag ue 4 vers l'ouverture 2a (cf. figures 7 à 10), en même temps que s'initie le vrillage du manchon 3. Ce déplacement axial réalise une rétractation de ladite première partie et de ladite partie intermédiaire du manchon 3 vers l'intérieur du corps 2, de telle sorte qu'un reste de produit présent sur cette première partie et cette partie intermédiaire se trouve amené en-deçà de la zone du manchon 3 destinée à être vrillée lors de l'obturation ;  - Displacement of the lugs 18 and 21 in the oblique grooves 14, 14 ', firstly producing an axial displacement of the bag ue 4 towards the opening 2a (see Figures 7 to 10), at the same time as initiates the twisting of the sleeve 3. This axial displacement effects a retraction of said first portion and of said intermediate portion of the sleeve 3 towards the inside of the body 2, so that a remainder of product present on this first portion and this intermediate portion is brought below the zone of the sleeve 3 intended to be twisted during sealing;
- échappement de l'ergot 18 hors de la rainure 14' et déplacement de l'ergot 21 dans la rainure circonférentielle 15, réalisant un déplacement guidé de la bague 4 en pivotement par rapport à la paroi périphérique 10, qui poursuit le vrillage du manchon ;  - Release of the lug 18 out of the groove 14 'and displacement of the lug 21 in the circumferential groove 15, providing a guided displacement of the ring 4 pivotally relative to the peripheral wall 10, which continues the twisting of the sleeve ;
- engagement de l'ergot 21 dans l'une ou l'autre des encoches 16 et maintien de cet ergot dans cette encoche, ce maintien étant réalisé par l'effet de rappel élastique axial qu'exerce le manchon 3 vrillé sur la bague 4 ; cet engagement permet de maintenir la bague 4 dans la position angulaire choisie, d'obturation partielle ou totale du récipient 1.  - Engagement of the lug 21 in one or the other of the notches 16 and maintaining this lug in this notch, this holding being achieved by the axial elastic return effect exerted by the sleeve 3 twisted on the ring 4 ; this engagement makes it possible to maintain the ring 4 in the selected angular position, partial or total closure of the container 1.
Lors de cette obturation partielle ou totale, le reste de produit précité se trouve sur la face interne de la membrane que forme le manchon 3 vrillé, et aucune présence de produit n'existe sur la face externe de cette membrane.  During this partial or total filling, the rest of the aforementioned product is on the inner face of the membrane formed by the sleeve 3 twisted, and no product presence exists on the outer face of this membrane.
L'encoche 16 la plus proche de la rainures 14 permet de maintenir la bague 4 dans la "position cuisson" montrée sur les figures 7 à 10 ; l'une ou l'autre des quatre encoches 16 suivantes permet de maintenir la bague 4 dans la "position paille" montrée sur les figures 1 1 à 14, avec application étanche de la membrane formée par le manchon 3 autour de cette paille ; l'encoches 16 située au bout de la rainure 15 permet de maintenir la bague 4 dans la position de complète obturation montrée sur les figures 15 à 18. Le mouvement de libération de l'ouverture 2a à partir de ladite position d'obturation se réalise selon une séquence inverse de celle détaillée ci-dessus. The notch 16 closest to the grooves 14 keeps the ring 4 in the "cooking position" shown in Figures 7 to 10; one or other of the following four notches 16 keeps the ring 4 in the "straw position" shown in Figures 1 1 to 14, with sealing application of the membrane formed by the sleeve 3 around this straw; the notches 16 located at the end of the groove 15 keeps the ring 4 in the position of complete closure shown in Figures 15 to 18. The release movement of the opening 2a from said closed position is performed in a sequence opposite to that detailed above.
Pour opérer un nettoyage du récipient 1 , la bague 4 étant dans ladite position de libération, l'utilisateur exerce un pivotement forcé de la bague pour franchir les marches séparant les rainures 12, 17 et 12', 17' ; les ergots 18, 21 parcourent alors les rainures de dégagement 17, 1 1 , 17' jusqu'à la position de dégagement montrée sur les figures 19 à 22. Ce déplacement de la bague 4 permet d'allonger le manchon 3 et donc de réaliser un nettoyage facilité du récipient 1 ; dans cette position, le rappel élastique du manchon 3 en position neutre permet de ramener les ergots 18, 21 en face des entrées 13, 13'.  To carry out a cleaning of the container 1, the ring 4 being in said release position, the user exerts a forced pivoting of the ring to cross the steps separating the grooves 12, 17 and 12 ', 17'; the lugs 18, 21 then run through the clearance grooves 17, 1 1, 17 'to the disengagement position shown in FIGS. 19 to 22. This displacement of the ring 4 makes it possible to lengthen the sleeve 3 and thus to achieve easy cleaning of the container 1; in this position, the elastic return of the sleeve 3 in the neutral position makes it possible to return the lugs 18, 21 in front of the inputs 13, 13 '.
Une fois le nettoyage opéré, la forme évasée de l'entrée 13 permet de guider l'ergot 21 vers la rainure 12 et facilite par conséquent le retour des deux ergots 18, 21 dans leurs rainures 12, 12' respectives.  Once the cleaning operation, the flared shape of the inlet 13 to guide the lug 21 to the groove 12 and therefore facilitates the return of the two lugs 18, 21 in their grooves 12, 12 'respectively.
Les figures 24 à 27 montrent la deuxième forme de réalisation du récipient 1 . Par simplification, les mêmes références numériques que dans la description de la première forme de réalisation sont réutilisées pour désigner des éléments ou des parties identiques ou similaires.  Figures 24 to 27 show the second embodiment of the container 1. For simplicity, the same reference numerals as in the description of the first embodiment are reused to designate elements or the same or similar parts.
Dans ce cas, la rainure 15 forme de nombreuses encoches 16, adjacentes les unes aux autres, dont chacune est délimitée par deux flancs de paroi sensiblement à angle droit l'un par rapport à l'autre. La rainure 15 est ainsi délimitée longitudinalement par un rebord en forme de dents de scie.  In this case, the groove 15 forms numerous notches 16, adjacent to each other, each of which is delimited by two wall flanks substantially at right angles to one another. The groove 15 is thus defined longitudinally by a rim shaped sawtooth.
L'ergot 21 présente une encoche sur son côté tourné vers les encoches 16, permettant l'engagement de cet ergot sur une ou l'autre des dents de scie formées par ledit rebord. Cet ergot 21 est ainsi apte à venir en prise avec ce rebord dans de nombreuses positions angulaires possibles de la bague 4 par rapport à la paroi 10.  The lug 21 has a notch on its side facing the notches 16, allowing the engagement of this lug on one or other of the saw teeth formed by said flange. This lug 21 is thus able to come into engagement with this rim in many possible angular positions of the ring 4 with respect to the wall 10.
L'ergot 21 présente également deux côtés opposés taillés en oblique, permettant son glissement ajusté dans la rainure oblique 14, ainsi que le montre la figure 26 en traits interrompus. Un parfait guidage de cet ergot 21 dans cette rainure oblique 14 est ainsi rendu possible.  The lug 21 also has two opposite sides cut obliquely, allowing its sliding fit in the oblique groove 14, as shown in Figure 26 in broken lines. Perfect guidance of this lug 21 in this oblique groove 14 is thus made possible.
Par ailleurs, la bague 4 comprend une paroi 25 faisant saillie le long du récipient 2, et ce dernier comprend un bossage 26. La paroi 25 vient buter contre ce bossage 26 en position de pleine ouverture du récipient 1 (cf. figure 24), ce qui assure un positionnement angulaire stable de la bague 4 dans cette position par rapport au récipient 2. La figure 28 montre l'ensemble de rainures 12' et 14' et l'entrée 13' diamétralement opposés à ceux précités, à l'instar de ce qui a été décrit pour la première forme de réalisation. Il est à noter, s'agissant de cette deuxième forme de réalisation, que la rainure 17 de dégagement se trouve entre les rainures 14 et 14, comme visible sur les figures 26 et 27. Furthermore, the ring 4 comprises a wall 25 projecting along the container 2, and the latter comprises a boss 26. The wall 25 abuts against the boss 26 in the fully open position of the container 1 (see FIG. which ensures a stable angular positioning of the ring 4 in this position relative to the container 2. Fig. 28 shows the set of grooves 12 'and 14' and the inlet 13 'diametrically opposed to those mentioned above, as has been described for the first embodiment. It should be noted, with respect to this second embodiment, that the clearance groove 17 is located between the grooves 14 and 14, as can be seen in FIGS. 26 and 27.
Comme cela apparaît de ce qui précède, l'invention fournit un récipient, notamment à usage alimentaire, présentant les avantages déterminants de donner parfaitement satisfaction en ce qui concerne sa manipulation ou les possibilités qu'il offre d'obturation/libération de son ouverture, et d'éliminer tout risque qu'un reste de produit soit présent sur la face extérieure de la membrane formée par le manchon à l'état de vrillage.  As appears from the foregoing, the invention provides a container, particularly for food use, having the decisive advantages of giving complete satisfaction with regard to its handling or the possibilities it offers to close / release its opening, and to eliminate any risk that a residue of product is present on the outer face of the membrane formed by the sleeve in the state of twisting.
L'invention a été décrite ci-dessus en référence à des formes de réalisation données à titre de purs exemples. Il va de soi qu'elle n'est pas limitée à ces formes de réalisation mais qu'elle s'étend à toutes les formes de réalisations couvertes par les revendications ci-annexées.  The invention has been described above with reference to embodiments given as pure examples.
