Abstract

A child resistant dispensing closure in which a threaded cap (34) must be fully removed from a container (14) to permit dispensing through an orifice (42) in a fitment (36) which remains sealed to the container. A plug (58) depending from the cap serves as a rotary seal, effective until a child resistant lock is released as the cap is being unthreaded.

Description

L'invention concerne les bouchons distributeurs, et plus particulierement des bouchons distributeurs à l'épreuve des enfants. The invention relates to dispenser caps, and more particularly to child-resistant dispenser caps.

Un type classique de bouchons distributeurs utilise habituellement une embase ou capsule qui est vissée sur le col d'un récipient, la capsule présentant un orifice de distribution à son sommet, et un couvercle articule sur l'embase pour se refermer de façon étanche sur l'orifice de distribution. A conventional type of dispensing cap usually uses a base or capsule which is screwed onto the neck of a container, the capsule having a dispensing orifice at its top, and a hinged cover on the base to close tightly on the dispensing orifice.

Un bouchon à l'épreuve des enfants est, par définition, un bouchon qu'un enfant a du mal à ouvrir. Les bouchons à l'épreuve des enfants les plus efficaces nécessitent deux mouvements ou actions indépendants et dissemblables pour enlever ou ouvrir le bouchon. Ces mouvements peuvent être simultanés ou successifs. A child-resistant cap is, by definition, a cap that a child has trouble opening. The most effective child-resistant plugs require two independent and dissimilar movements or actions to remove or open the plug. These movements can be simultaneous or successive.

Le fait de rendre résistant aux enfants un bouchon distributeur du type à dessus rabattable ajoute à la complexité du bouchon et du processus de moulage. Making a dispenser cap of the flip top type child resistant adds to the complexity of the cap and the molding process.

Cependant, il existe des bouchons de ce type qui donnent satisfaction, par exemple comme décrit dans la demande de brevet des Etats-Unis d'Amerique n 189 109, déposée le 2
Mai 1988. Il existe également divers bouchons distributeurs comportant une capsule captive qui n'est pas ou ne peut pas normalement être enlevee du col du récipient, mais qui sont partiellement dévissés pour ouvrir un passage de distribu tion . Ce type de capsule est nécessairement en deux pièces comportant une capsule extérieure dont le sommet est traverse par l'orifice de distribution et un accessoire intérieur qui ferme l'orifice lorsque la capsule extérieure est vissée hermétiquement. Le bouchon à capsule captive n'est pas à l'épreuve des enfants, mais on peut lui conférer une résistance aux enfants.However, there are plugs of this type which give satisfaction, for example as described in the patent application of the United States of America No. 189 109, filed on 2
May 1988. There are also various dispenser caps with a captive cap which is not or cannot normally be removed from the neck of the container, but which are partially unscrewed to open a dispensing passage. This type of capsule is necessarily in two parts comprising an external capsule whose apex is crossed by the dispensing orifice and an interior accessory which closes the orifice when the external capsule is hermetically screwed. The captive cap is not child-resistant, but can be given child resistance.

La présente invention prévoit l'utilisation d'un dispositif bien connu à l'épreuve des enfants, du type "Squeeze Lok ", appliqué à des capsules vissées normalisées, dont des types sont illustrés dans les brevets des Etats-Unis d'Amérique n 3 770 153, n 3 826 395 et n 3 989 152. The present invention provides for the use of a well-known child-proof device, of the "Squeeze Lok" type, applied to standard screw-on capsules, of which types are illustrated in United States patents n 3,770,153, 3,826,395 and 3,989,152.

L'invention concerne un bouchon à l'épreuve des enfants qui comporte un dispositif extérieur de verrouillage du type ci-dessus, donnant une indication visuelle du fait que, lorsque le bouchon a été reposé sur le récipient, il a été rétabli à son état à l'épreuve des enfants, ainsi qu'un bouchon qui réalise une obturation étanche au moment où avant que la résistance aux enfants devienne efficace et reste fermée hermétiquement par un vissage supplémentaire quelconque l'amenant dans une position serrée, ou par un dévissage jusqu'à ce que la résistance aux enfants soit relâchée. L'invention prévoit l'utilisation de ces particularités dans un bouchon distributeur. The invention relates to a child-resistant stopper which has an external locking device of the above type, giving a visual indication that when the stopper has been placed on the container, it has been restored to its state. childproof, as well as a stopper which achieves a watertight seal at the time before the resistance to children becomes effective and remains hermetically closed by any additional screwing bringing it into a tight position, or by unscrewing until 'that resistance to children is relaxed. The invention provides for the use of these features in a dispenser cap.

Le bouchon selon l'invention est destiné à être utilisé sur un récipient comportant une butée de verrouillage et un col fileté. Le col du récipient comporte également un rebord s'étendant vers l'extérieur au-dessus des filets. The stopper according to the invention is intended to be used on a container comprising a locking stop and a threaded neck. The container neck also has an outwardly extending rim above the threads.

Le bouchon distributeur à l'épreuve des enfants selon l'invention est en deux pièces comportant une capsule et une monture. La capsule comporte un dessus plan non perforé et une jupe annulaire qui part vers le bas du dessus. Des filets intérieurs, prévus sur la capsule, sont complémentaires des filets extérieurs du recipient. Le dispositif à l'épreuve des enfants se présente sous la forme d'un organe d'arrêt pouvant être libéré manuellement, situé sur la capsule et pouvant s'enclencher avec la butée du récipient pendant que la capsule est dévissée du col du récipient. The child-resistant dispensing cap according to the invention is in two parts comprising a capsule and a frame. The capsule has a non-perforated flat top and an annular skirt which extends down from the top. Internal threads, provided on the capsule, are complementary to the external threads of the container. The child-resistant device is in the form of a manually releasable stop member located on the capsule and capable of engaging with the container stopper while the capsule is unscrewed from the container neck.

La seconde pièce du bouchon se présente sous la forme d'une monture qui comporte un dessus traversé par un orifice central de distribution, et une courte jupe annulaire qui part vers le bas de la périphérie du dessus. The second piece of the plug is in the form of a frame which has a top crossed by a central dispensing orifice, and a short annular skirt which extends downwards from the periphery of the top.

La jupe de la monture comporte un bourrelet dirige vers l'intérieur, destiné à coopérer avec le rebord du col du récipient pour relier de façon étanche et permanente la monture au col du récipient.The skirt of the frame has a bead directed inwards, intended to cooperate with the rim of the neck of the container in order to connect the frame in a sealed and permanent manner to the neck of the container.

La capsule comporte un obturateur en saillie vers le bas, concentrique et intérieur à la jupe annulaire pour s'enclencher avec la monture ou le support afin d'ouvrir et de refermer l'orifice de distribution lorsque la capsule est dévissée du col du récipient ou est vissée sur ce col. L'obturateur forme un joint tournant d'etanchéité qui maintient efficacement le contact étanche avec l'orifice distributeur pendant que la capsule est dévissée de la position totalement bloquée au-delà d'une position dans laquelle l'organe d'arrêt est dégagé manuellement de la butée du récipient. Ceci assure que même si un enfant dévisse partiellement la capsule jusqu'à la butée du récipient, le bouchon reste ferme hermétiquement. The capsule comprises a shutter projecting downward, concentric and internal to the annular skirt to engage with the frame or the support in order to open and close the dispensing orifice when the capsule is unscrewed from the neck of the container or is screwed on this collar. The shutter forms a rotating sealing joint which effectively maintains tight contact with the dispensing orifice while the capsule is unscrewed from the fully locked position beyond a position in which the stop member is released manually. of the container stop. This ensures that even if a child partially unscrews the capsule until the container stops, the cap remains tightly closed.

La monture peut être posée séparément sur le col du récipient, mais, plus souvent, elle est insérée dans la capsule afin qu'une seule opération de coiffage soit nécessaire. Lorsque la monture est insérée dans la capsule, elle est retenue de manière particulière par la coopération de ltobturateur de la capsule avec l'orifice de la monture. The frame can be placed separately on the neck of the container, but, more often, it is inserted into the capsule so that a single styling operation is necessary. When the frame is inserted into the capsule, it is retained in a particular way by the cooperation of the obturator of the capsule with the orifice of the frame.

Lorsque le bouchon est vissé sur le col du récipient, la monture s'enclenche de façon permanente avec le col par la coopération du bourrelet de la monture avec le rebord du col du récipient. Ensuite, l'obturateur sert à ouvrir et refermer hermétiquement l'orifice de distribution. La retenue de la monture à l'intérieur de la capsule avant la pose initiale sur le col du recipient est assurée par un ajustement serré entre l'orifice de la monture et l'obturateur de la capsule.When the stopper is screwed onto the neck of the container, the frame permanently engages with the neck by the cooperation of the bead of the frame with the rim of the neck of the container. Then, the shutter is used to open and close the dispensing orifice hermetically. The retention of the frame inside the capsule before the initial installation on the neck of the container is ensured by a tight fit between the orifice of the frame and the shutter of the capsule.

Dans une forme préférée de réalisation du bouchon, la capsule comporte une jupe double, une jupe intérieure étant concentrique à une jupe extérieure. Les filets intérieurs sont situés sur la jupe intérieure et l'organe d'arrêt amovible est situé sur la jupe extérieure. In a preferred embodiment of the stopper, the capsule comprises a double skirt, an inner skirt being concentric with an outer skirt. The inner threads are located on the inner skirt and the removable stop member is located on the outer skirt.

L'organe d'arrêt pouvant être libéré manuellement se présente sous la forme de deux pattes diamétralement opposées, qui font saillie axialement vers le bas de la jupe extérieure, et la butée du récipient se présente sous la forme de deux surfaces de butée diamétralement opposées.The manually releasable stop member is in the form of two diametrically opposite tabs which project axially downwards from the outer skirt, and the stop of the container is in the form of two diametrically opposite stop surfaces .

Les pattes passent sur les surfaces de butée pendant que la capsule est vissée sur le col du récipient, mais elles butent contre les surfaces de butée lorsque la capsule est dévissée afin d'empêcher la poursuite du dévissage jusqu'à ce que les pattes soient libérées manuellement pendant que la capsule est dévissée. De plus, dans la forme préférée de réalisation, deux patins opposés de pression sont prévus sur la jupe annulaire, centrés dans un plan perpendiculaire au plan passant par les pattes s'étendant axialement afin qu'une libération manuelle soit effectuée par l'application d'une pression vers l'intérieur sur les patins et un déplacement des pattes vers l'extérieur pour dégager les surfaces de butée pendant que la capsule est dévissée.The tabs pass over the abutment surfaces while the capsule is screwed onto the container neck, but they abut against the abutment surfaces when the capsule is unscrewed to prevent further unscrewing until the tabs are released manually while the capsule is unscrewed. In addition, in the preferred embodiment, two opposite pressure pads are provided on the annular skirt, centered in a plane perpendicular to the plane passing through the axially extending tabs so that manual release is effected by the application of 'Inward pressure on the pads and movement of the legs outward to release the abutment surfaces while the capsule is unscrewed.

L'emballage à récipient et bouchon selon l'invention, dans une forme préférée de réalisation, utilise aussi un bourrelet d'étanchéité sur le col du récipient, au-dessous de la butée du récipient pour assumer une fonction d'étanchéité secondaire. De plus, les butées du récipient se présentent sous la forme d'organes de contact qui présentent des surfaces de came d'entrée déviant les pattes de la capsule vers l'extérieur pendant le vissage de la capsule sur le récipient, afin de les dégager des butées. The container and stopper packaging according to the invention, in a preferred embodiment, also uses a sealing bead on the neck of the container, below the stop of the container, to assume a secondary sealing function. In addition, the stops of the container are in the form of contact members which have entry cam surfaces deviating the tabs of the capsule towards the outside during the screwing of the capsule on the container, in order to release them. stops.

Ainsi qu'on peut mieux le voir sur la figure 1, l'emballage 10 à récipient et bouchon comprend un bouchon 12 en deux pièces et un récipient 14. Ce dernier comporte une partie d'épaule 16 se prolongeant par un col 18 qui présente des filets extérieurs 20 destinés à recevoir le bouchon. Le col comporte un tronçon étroit au-dessus des filets 20, se terminant par une lèvre annulaire 22 définissant un orifice 24 de distribution. Un rebord ou bourrelet 26 en saillie vers l'extérieur est situé sur le col étroit à proximité de la lèvre annulaire 22. Un bourrelet 28 de détachement fait saillie vers l'extérieur au-dessous des filets 20. Deux butées 30 et 32, comme on peut mieux le voir sur la figure 5, font également saillie diamétralement vers l'extérieur du col 18 ou de l'épaule 16. As can best be seen in FIG. 1, the package 10 with container and stopper comprises a stopper 12 in two parts and a container 14. The latter has a shoulder part 16 extended by a neck 18 which has external threads 20 intended to receive the plug. The neck has a narrow section above the threads 20, ending in an annular lip 22 defining a dispensing orifice 24. A flange or bead 26 projecting outwards is situated on the narrow neck near the annular lip 22. A detachment bead 28 projects outwards below the threads 20. Two stops 30 and 32, as this can best be seen in FIG. 5, also protruding diametrically towards the outside of the neck 18 or the shoulder 16.

Le bouchon distributeur 12 en deux pièces comporte une capsule globalement cylindrique 34 et une monture 36. Cette dernière comporte un dessus globalement plan 38 et une courte jupe descendante 40. Un orifice 42 de distribution s'étend à travers le dessus 38 et, dans la plupart des cas, une buse ou un bec 44 orienté vers le haut entoure l'orifice 42 afin de diriger le produit distribue à partir du récipient 14. La dimension de l'orifice 42 et le contour du bec ou de la buse 44 peuvent être de conception spéciale pour le produit particulier à distribuer, qui est habituellement une matière du type liquide ou gel, telle qu'un detergent liquide pour machine à laver la vaisselle.Un bourrelet 46 d'encliquetage, faisant saillie vers l'intérieur à proximité immédiate du bas de la jupe 40, est destiné à coopérer avec le rebord 26 du col du récipient pour encliqueter la monture 36 sur le col du récipient afin qu'elle soit retenue de façon permanente et étanche sur celui-ci. Le bourrelet 26 du col du récipient réalise un joint étanche permanent avec la surface intérieure 48 de la jupe 40 de la monture comme on peut mieux le voir sur la figure 3. The two-piece distributor cap 12 has a generally cylindrical capsule 34 and a mount 36. The latter has a generally planar top 38 and a short descending skirt 40. A dispensing orifice 42 extends through the top 38 and, in the in most cases, an upwardly directed nozzle or spout 44 surrounds the orifice 42 in order to direct the product dispensed from the container 14. The dimension of the orifice 42 and the outline of the spout or the nozzle 44 can be of special design for the particular product to be dispensed, which is usually a liquid or gel-like material, such as a liquid detergent for a dishwashing machine. A snap-on bead 46 projecting inwardly in the immediate vicinity from the bottom of the skirt 40, is intended to cooperate with the rim 26 of the container neck to snap the frame 36 onto the container neck so that it is permanently and tightly retained thereon . The bead 26 of the neck of the container makes a permanent tight seal with the internal surface 48 of the skirt 40 of the frame as can best be seen in FIG. 3.

La capsule 34 comporte une jupe extérieure 50 et une jupe intérieure 52 qui sont concentriques comme on peut mieux le voir sur la figure 2. La jupe intérieure-52 comporte des filets intérieurs 54 destinés à s'enclencher avec les filets 20 du récipient. La capsule 34 comporte un dessus plan ou légèrement incurvé, non perforé 56, duquel part vers le bas un obturateur 58 concentrique aux jupes extérieure et intérieure 50 et 52. L'obturateur 58 diverge vers l'extérieur à partir du dessus 56 de la capsule jusqu'à son extrémité distale et s'engage dans l'orifice 42 et avec la buse 44, en un ajustement serré pour former le joint étanche principal entre la capsule 34 et la monture 36. The capsule 34 has an outer skirt 50 and an inner skirt 52 which are concentric as can best be seen in FIG. 2. The inner skirt-52 has internal threads 54 intended to engage with the threads 20 of the container. The capsule 34 has a flat or slightly curved, non-perforated top 56, from which a shutter 58 concentric with the outer and inner skirts 50 and 52 extends downward. The shutter 58 diverges outward from the top 56 of the capsule up to its distal end and engages in the orifice 42 and with the nozzle 44, in a tight fit to form the main watertight seal between the capsule 34 and the frame 36.

La monture 36 peut être posée séparément sur le col du récipient comme on le voit sur la figure 4, ou bien, plus communément, elle est insérée dans la capsule 34 pour y être retenue, ce qui permet de transporter le bouchon 12 d'un seul bloc jusqu' l'emballeur final. L'ajustement étroit entre la buse 42 et l'obturateur 58 retient fixement la monture à l'intérieur de la jupe intérieure 52. Un rebord annulaire 60 part vers le bas du dessus 56 de la capsule et est d'une longueur appropriée pour porter contre le dessus 58 de la monture, laissant un faible jeu entre le dessus de la buse 44 de la monture et l'intérieur du dessus 56 de la capsule.Pendant que la capsule 34 est vissée sur le col 18 du récipient, le rebord 60 exerce une force vers le bas sur le dessus 38 de la monture afin que le rebord 46 de cette monture s'encliquette par dessus le rebord 26 du récipient durant cette opération initiale de coiffage. The mount 36 can be placed separately on the container neck as seen in Figure 4, or, more commonly, it is inserted into the capsule 34 to be retained there, which allows to transport the cap 12 of a single block to the final packer. The close fit between the nozzle 42 and the shutter 58 fixedly retains the frame inside the inner skirt 52. An annular flange 60 extends down from the top 56 of the capsule and is of a length suitable for carrying against the top 58 of the frame, leaving a slight clearance between the top of the nozzle 44 of the frame and the inside of the top 56 of the capsule. While the capsule 34 is screwed onto the neck 18 of the container, the flange 60 exerts a downward force on the top 38 of the frame so that the rim 46 of this frame snaps over the rim 26 of the container during this initial styling operation.

Ensuite, la monture est retenue de façon permanente en position d'étanchéité sur le col du récipient. Puis l'obturateur 58 sert à obturer hermétiquement l'orifice 42.Then, the frame is permanently retained in the sealing position on the neck of the container. Then the shutter 58 serves to hermetically seal the orifice 42.

Avec l'ajustement étroit et la longueur axiale de ltob- turateur 58 et de la buse 44, le joint étanche est maintenu durant l'action initiale de dévissage de la capsule 34.With the narrow adjustment and the axial length of the shutter 58 and of the nozzle 44, the tight seal is maintained during the initial unscrewing action of the capsule 34.

Une bague 62 d'étanchéité, en forme de V, part vers le bas du dessus 38 de la monture pour former un joint étanche secondaire de la monture avec la levre annulaire 22 du col 18 du récipient. De plus, une bague 64 d'étanchéité en forme de V part vers le bas du dessous du rebord annulaire 60 pour former un joint étanche secondaire de la capsule avec la monture. Les bagues d'étanchéité 62 et 64 ont le même diamètre, concentrant la force d'étanchéité entre la capsule 34 et la monture 36 et la force entre la monture 36 et la levure 22 du récipient, suivant une ligne. A sealing ring 62, in the shape of a V, extends downwards from the top 38 of the frame to form a secondary tight seal of the frame with the annular lip 22 of the neck 18 of the container. In addition, a V-shaped sealing ring 64 extends down from the underside of the annular rim 60 to form a secondary seal of the capsule with the frame. The sealing rings 62 and 64 have the same diameter, concentrating the sealing force between the capsule 34 and the frame 36 and the force between the frame 36 and the yeast 22 of the container, along a line.

Un autre joint étanche est établi entre la capsule 34 et le col 18 du récipient par la coopération du bourrelet 28 du col du récipient et du dessous de la jupe intérieure 52, comme on peut mieux le voir sur la figure 2.Another leaktight seal is established between the capsule 34 and the neck 18 of the container by the cooperation of the bead 28 of the neck of the container and of the underside of the inner skirt 52, as can best be seen in FIG. 2.

Un verrou à l'épreuve des enfants, sous la forme d'un organe d'arrêt pouvant être libéré manuellement, est prévu sur le bouchon 12 pour coopérer avec les butées 30, 32 du récipient. Dans la forme préférée de réalisation de l'invention utilisant une capsule à double jupe, ce verrou se présente sous la forme de deux pattes ou d'une languette 66 et 68, diamétralement opposées, s'étendant axialement vers le bas de la jupe extérieure 50 et qui coopèrent avec des butées 30 et 32 faisant saillie vers l'extérieur du récipient. Pendant que la capsule 34 est vissée sur le col 18 du récipient, les pattes 66 et 68 sont déviées vers l'extérieur par des surfaces de came 70 et 72 des butées 30 et 32 du récipient.Cette déviation vers l'extérieur de la paroi extérieure 50 et de la patte 58 est représentée en traits mixtes sur la figure 2 en tant que partie de paroi 50' et patte 68'. Lorsque les pattes dépassent leurs butees respectives, elles reprennent, avec la partie de paroi, leur position normale vers l'intérieur comme montré sur la figure 2. La capsule peut continuer à être tournée jusqu'a ce qu'elle soit completement vissée sur les filets du col du recipient. La figure 5 montre les pattes 66 et 68 en coupe transversale avant l'entrée- en contact avec les butées 30 et 32 du récipient. . Les positions des pattes, lorsqu'elles entrent en contact initial avec les surfaces de came 70 et 72, sont représentées en traits mixtes en 66' et 68'. Les pattes sont représentées en 662 et 682 dans leur position déviée au maximum par les surfaces de came, et elles sont représentées en 663 et 683 dans la position qu'elles prendraient si elles retombaient des surfaces de came 70 et 72 des butées sur l'épaule 16. La capsule peut être serrée sur 90 supplémentaires jusqu'à une position totalement bloquée représentée par les positions des pattes en 664 et 684. A child-resistant lock, in the form of a stopper that can be released manually, is provided on the plug 12 to cooperate with the stops 30, 32 of the container. In the preferred embodiment of the invention using a capsule with double skirt, this lock is in the form of two tabs or of a tongue 66 and 68, diametrically opposite, extending axially downwards from the outer skirt 50 and which cooperate with stops 30 and 32 projecting towards the outside of the container. While the capsule 34 is screwed onto the neck 18 of the container, the tabs 66 and 68 are deflected towards the outside by cam surfaces 70 and 72 of the stops 30 and 32 of the container. This deflection towards the outside of the wall outer 50 and the tab 58 is shown in phantom in Figure 2 as a wall portion 50 'and tab 68'. When the tabs exceed their respective stops, they resume, with the wall portion, their normal position inward as shown in Figure 2. The capsule can continue to be rotated until it is completely screwed on the fillets from container neck. Figure 5 shows the legs 66 and 68 in cross section before coming into contact with the stops 30 and 32 of the container. . The positions of the tabs, when they come into initial contact with the cam surfaces 70 and 72, are shown in phantom in 66 'and 68'. The legs are shown in 662 and 682 in their position deviated to the maximum by the cam surfaces, and they are shown in 663 and 683 in the position they would assume if they fell from the cam surfaces 70 and 72 of the stops on the shoulder 16. The capsule can be clamped on an additional 90 to a completely locked position represented by the positions of the tabs at 664 and 684.

Lorsque la capsule 34 est dévissée, elle ne peut être tournée que jusqu'au point où les pattes 66 et 68 entrent en contact avec les surfaces de butée 74 et 76 des butées 30 et 32 du récipient. Cette position est représentée en 663 et 683 sur la figure 5. Les pattes 66 et 68 doivent être déviées manuellement vers l'extérieur pour se dégager des butées 30 et 32 en même temps que la capsule est dévissée par rotation dans le sens contraire à celui des aiguilles d'une montre. Cette déviation manuelle vers l'extérieur s'effectue par l'application d'une pression sur des parties de tampon 78 diamétralement opposées, dont une seule est montrée sur les figures 1 et 2. Ces tampons 78 sont placés dans un plan à 90 du plan passant par le centre des pattes descendantes 66 et 68. When the capsule 34 is unscrewed, it can only be turned to the point where the tabs 66 and 68 come into contact with the abutment surfaces 74 and 76 of the abutments 30 and 32 of the container. This position is shown at 663 and 683 in FIG. 5. The legs 66 and 68 must be manually deflected outward to disengage from the stops 30 and 32 at the same time as the capsule is unscrewed by rotation in the opposite direction to that clockwise. This manual deflection outwards is effected by the application of pressure on the diametrically opposite parts of the pad 78, only one of which is shown in FIGS. 1 and 2. These pads 78 are placed in a plane 90 ° from the plan passing through the center of the descending legs 66 and 68.

I1 apparaît que les butées 30 et 32 du récipient pourraient s'élever de l'épaule 16 à distance du col 18 de la maniere montrée sur les figures 1 à 3 dans le brevet des Etats-Unis d'Amerique n 3 989 152 précité afin qu'une pression vers l'intérieur sur la jupe 50 de la capsule, en alignement avec les pattes 66 et 68, déplace davantage les pattes vers l'intérieur pour les dégager des butées du récipient. De la même manière, d'autres formes de pattes à comprimer peuvent être utilisées comme montré sur les figures 4 à 6 de ce brevet afin que la capsule ne comporte qu'une seule jupe. I1 appears that the stops 30 and 32 of the container could rise from the shoulder 16 at a distance from the neck 18 in the manner shown in FIGS. 1 to 3 in the aforementioned United States patent No. 3,989,152 so that an inward pressure on the skirt 50 of the capsule, in alignment with the legs 66 and 68, moves the legs further inward to disengage them from the stops of the container. Similarly, other forms of tabs to be compressed can be used as shown in Figures 4 to 6 of this patent so that the capsule has only one skirt.

L'obturateur 58 maintient son contact étanche avec l'orifice 42 et la buse 44 a partir d'une position située en avant ou au niveau des surfaces de butée 30 et 32, en passant par la position totalement bloquée, montrée en 664 et 68, jusqu'a ce qu'il soit dégagé des butées du récipient conne représenté en traits pleins en 66 et 68 sur la figure 5.
