The cap (4) is then driven in rotation by the cover (3) and can consequently be unscrewed in order to open the bottle. <IMAGE>

Description

La présente invention a trait aux bouchons dits "de sécurité" (parfois également désignés sous le mot anglais "childproof"), destinés à l'obturation des flacons, bouteilles et autres récipients renfermant des produits dangereux pour les enfants en bas âge (produits pharmaceutiques, produits chimiques, produitsde droguerie, etc...)The present invention relates to so-called "safety" stoppers (sometimes also known as the English word "childproof"), intended for closing vials, bottles and other containers containing products dangerous for young children (pharmaceutical products , chemicals, drugstore products, etc.)

On sait que ces bouchons de sécurité comprennent généralement deux éléments distincts, à savoir une capsule interne d'obturation apte à se visser sur le goulot fileté du flacon, et une cape extérieure d'actionnement agencée de manière à ne permettre l'entraînement en rotation de ladite capsule au dévissage que moyennant deux manoeuvres combinées, la seule rotation de la cape ne pouvant aboutir au dévissage de la capsule.It is known that these safety caps generally comprise two separate elements, namely an internal closure cap capable of being screwed onto the threaded neck of the bottle, and an outer actuating cap arranged so as to not allow the drive to rotate. from said capsule to unscrewing only by means of two combined maneuvers, the only rotation of the cape being unable to unscrew the capsule.

Différents agencements on été proposés en pratique, mais le problème est en fait plus difficile qu'il peut paraître à première vue. En effet, pour qu'un bouchon de sécurité puisse donner entière satisfaction, il y a lieu qu'il réunisse les conditions suivantes:

  • 1. - Il faut que la manoeuvre au dévissage soit suffisamment complexe pour dérouter un enfant, mais suffisamment simple pour être aisément mémorisée pour un adulte ne disposant pas d'une habilité et d'une force particulières;
  • 2. - Il faut que la manoeuvre soit susceptible d'être exécutée par les mal-voyants, étant observé que ceux-ci ne peuvent évidemment se référer à un mode d'emploi ou à des signes gravés sur le bouchon ou sur le flacon;
  • 3. - Il faut que le profil de la capsule et de la cape reste suffisamment simple pour permettre une fabrication économique en matière plastique moulée;
  • 4. - Il faut encore que le bouchon ne présente pas en encombrement trop important, de façon à ce qu'il puisse convenir pour des flacons de petite contenance à diamètre réduit.
Different arrangements have been proposed in practice, but the problem is actually more difficult than it may seem at first glance. Indeed, for a safety cap to be entirely satisfactory, it should meet the following conditions:
  • 1. - The unscrewing maneuver must be complex enough to confuse a child, but simple enough to be easily memorized for an adult who does not have a particular skill and strength;
  • 2. - The maneuver must be capable of being carried out by the visually impaired, it being observed that they cannot obviously refer to instructions for use or to signs engraved on the cap or on the bottle;
  • 3. - It is necessary that the profile of the capsule and of the cape remain simple enough to allow an economical manufacture in molded plastic;
  • 4. - It is also necessary that the stopper does not present in too large bulk, so that it can be suitable for small-capacity bottles with diameter reduced.

La présente invention a pour objet un bouchon de sécurité qui répond particulièrement bien aux impératifs ci-dessus rappelés.The present invention relates to a safety cap which responds particularly well to the above-mentioned requirements.

A cet effet, dans le bouchon suivant l'invention, la liaison angulaire entre la capsule d'obturation et la cape d'actionnement est assurée à l'aide d'au moins une patte déformable obtenue par découpage partiel de la paroi latérale de ladite cape, laquelle patte comporte sur sa face interne une saillie propre, à la suite d'une pression exercée radialement sur ladite patte, à venir coopérer avec une butée correspondante prévue sur la face externe de la capsule.To this end, in the stopper according to the invention, the angular connection between the closure cap and the actuating cap is ensured using at least one deformable tab obtained by partial cutting of the side wall of said cap. cap, which tab has on its internal face a clean projection, following a pressure exerted radially on said tab, to cooperate with a corresponding stop provided on the outer face of the capsule.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer:

  • Fig. 1 est une coupe axiale schématique montrant un bouchon de sécurité suivant l'invention, supposé monté sur le goulot d'un flacon.
  • Fig. 2 est une vue en perspective de la cape extérieure d'actionnement de ce bouchon.
  • Fig. 3 représente de la même manière la capsule interne d'obturation.
  • Fig. 4 est une coupe analogue à celle de fig. 1, mais illustrant la position des pièces lors du dévissage du bouchon (ouverture du flacon).
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 is a schematic axial section showing a safety cap according to the invention, assumed to be mounted on the neck of a bottle.
  • Fig. 2 is a perspective view of the outer cap for actuating this plug.
  • Fig. 3 shows in the same way the internal closure capsule.
  • Fig. 4 is a section similar to that of FIG. 1, but illustrating the position of the parts when unscrewing the cap (opening the bottle).

En fig. 1, on a représenté en 1 le goulot d'un flacon en verre dont la bague ou carnette 10 porte un filetage extérieur 11. Dans l'ouverture du goulot 1 est engagé un obturateur 2 de type usuel (susceptible d'ailleurs d'être remplacé par un disque plat d'étanchéité), maintenu en place par le bouchon suivant l'invention, lequel est formé par l'assemblage de deux pièces distinctes 3 et 4.In fig. 1, there is shown at 1 the neck of a glass bottle whose ring or book 10 carries an external thread 11. In the opening of the neck 1 is engaged a shutter 2 of the usual type (likely also to be replaced by a flat sealing disc), held in place by the plug according to the invention, which is formed by the assembly of two separate rooms 3 and 4.

Comme plus particulièrement montré en fig. 2, la pièce 3 est constituée par une cape extérieure réalisée en matière plastique moulée et comprenant une jupe cylindrique 30 crénelée extérieurement pour faciliter sa préhension et fermée vers le haut par un fond trasversal 31. La jupe 30 et le fond 31 sont profilés pour présenter une partie en renfoncement 32 formant logement pour une patte déformable 33, laquelle est constituée par une partie de la jupe 30 située entre deux fentes verticales 34 qui s'arrêtent à une faible distance au-dessus du bord inférieur libre de ladite jupe. On observera que la hauteur de la patte 33 est inférieure à celle du renfoncement 32, de telle sorte que cette patte peut être aisément repérée moyennant un simple tâtonnement exercé sur la jupe 30.As more particularly shown in fig. 2, the part 3 is constituted by an outer cap made of molded plastic and comprising a cylindrical skirt 30 crenellated externally to facilitate its gripping and closed upwards by a transverse bottom 31. The skirt 30 and the bottom 31 are profiled to present a recessed portion 32 forming a housing for a deformable tab 33, which is constituted by a part of the skirt 30 located between two vertical slots 34 which stop a short distance above the free lower edge of said skirt. It will be observed that the height of the tab 33 is less than that of the recess 32, so that this tab can be easily identified by means of a simple trial and error exerted on the skirt 30.

A la manière montrée en fig. 1, le bord inférieur de la jupe 30 comporte un bourrelet intérieur 35, tandis que le bord supérieur de la patte déformable 33 est lui-même solidaire d'une saillie 36, également tournée vers l'intérieur. Par ailleurs, la paroi interne du fond transversal 31 présente des dents 37, au nombre de quatre dans l'exemple de réalisation envisagé; la paroi inférieure de chaque dent 37 est prévue oblique, un peu à la manière d'une dent de cliquet.As shown in fig. 1, the lower edge of the skirt 30 has an inner bead 35, while the upper edge of the deformable tab 33 is itself secured to a projection 36, also facing inward. Furthermore, the internal wall of the transverse bottom 31 has teeth 37, four in number in the exemplary embodiment envisaged; the bottom wall of each tooth 37 is provided oblique, somewhat in the manner of a ratchet tooth.

La pièce 4 du bouchon suivant l'invention est constituée par une capsule interne d'obturation, réalisée en matière plastique moulée. Comme représenté en fig. 3, cette capsule 4 comprend une jupe latérale 40 à profil général substantiellement cylindrique, fermée par un fond transversal supérieur 41, lequel est pourvu de dents en saillie 42, analogues à celles 37 de la cape 3, mais tournées à l'opposé. Le bord inférieur libre de la jupe 40 présente un surépaissement 43, raidi par de petites entretoises 44; l'on notera que le diamètre extérieur de ce surépaissement 43 est légèrement supérieur au diamètre interne du bourrelet 35, de façon à ce que ce dernier puisse, moyennant une déformation élastique momentanée, venir se disposer au-dessous du surépaississement 43 (voir fig. 1), en opérant de la sorte la retenue axiale lâche de la cape 3 sur la capsule 4. Cette dernière comporte au niveau de sa paroi intérieure un filetage 45 apte à coopérer avec le filetage 11 du goulot 1.The part 4 of the plug according to the invention consists of an internal closure capsule, made of molded plastic. As shown in fig. 3, this capsule 4 comprises a side skirt 40 with a substantially cylindrical general profile, closed by an upper transverse bottom 41, which is provided with projecting teeth 42, similar to those 37 of the cap 3, but turned opposite. The free lower edge of the skirt 40 has a thickening 43, stiffened by small spacers 44; it will be noted that the external diameter of this over-thickness 43 is slightly greater than the internal diameter of the bead 35, so that the latter can, by means of a momentary elastic deformation, come to be disposed below the over-thickening 43 (see fig. 1), in operating in this way the loose axial retention of the cap 3 on the capsule 4. The latter comprises at its inner wall a thread 45 capable of cooperating with the thread 11 of the neck 1.

Revenant à fig. 3, on peut voir que la paroi extérieure de la jupe 40 présente, en un point de sa périphérie, une partie en renfoncement 46 orienté de manière légèrement oblique afin de déterminer une butée longitudinale 47, alors qu'à l'opposé ledit renfoncement se raccorde pratiquement sans heurt avec la périphérie de ladite jupe 40. Il convient d'observer que ce renfoncement 46 est fermé vers le bas par une cloison 48 en forme de piste à profil courbe, laquelle cloison est bordée extérieurement par un rebord 49 qui s'arrête un peu en retrait par rapport à la zone de raccordement dudit renfoncement 46 avec la périphérie de la jupe 40.Returning to fig. 3, it can be seen that the outer wall of the skirt 40 has, at a point on its periphery, a recess portion 46 oriented in a slightly oblique manner in order to determine a longitudinal stop 47, while on the opposite side said recess is connects practically smoothly with the periphery of said skirt 40. It should be observed that this recess 46 is closed downwards by a partition 48 in the form of a track with a curved profile, which partition is bordered externally by a flange 49 which s stops slightly behind the connection area of said recess 46 with the periphery of the skirt 40.

On comprend que lorsque les deux pièces 3 et 4 sont assemblées l'une à l'autre à la manière illustrée en fig.1, la manoeuvre exercée par l'utilisateur sur la cape 4 dans le sens des aiguilles d'une montre a pour effet de visser l'ensemble du bouchon sur le goulot 1 en assurant l'application à force de l'obturateur 2. Effectivement, au cours de la mise en rotation initiale de la cape 3, les dents 37 du fond 31 de celle-ci viennent porter contre les dents 42 du fond 41 de la capsule 4 qui est alors elle-même entraînée en rotation.It is understood that when the two parts 3 and 4 are assembled to one another in the manner illustrated in fig.1, the operation exerted by the user on the cape 4 in the clockwise direction has for effect of screwing the entire plug onto the neck 1 ensuring the application by force of the shutter 2. Actually, during the initial rotation of the cap 3, the teeth 37 of the bottom 31 thereof come to bear against the teeth 42 of the bottom 41 of the capsule 4 which is then itself rotated.

Par contre si l'on se contente, comme le fera normalement un enfant en bas âge ou une personne non avertie, de tourner la cape 4 dans le sens inverse des aiguilles d'une montre une fois que le bouchon a été mis en place sur le flacon comme sus-indiqué, les dents 42 et 37 glissent les unes sur les autres en provoquant, en même temps qu'un cliquetis, l'élévation et l'abaissement alternatifs de la cape 3 sur la capsule 4, mais sans entraîner en rotation cette dernière qui est maintenue en position de fermeture.On the other hand, if one is content, as a young child or an uninformed person will normally do, to turn cape 4 anti-clockwise once the cap has been put on the bottle as indicated above, the teeth 42 and 37 slide one over the other, causing, at the same time as a clicking, the alternative raising and lowering of the cap 3 on the capsule 4, but without causing rotation which is held in the closed position.

Pour obtenir le dévissage de cette capsule et l'ouverture du flacon, il faut que l'utilisateur exerce, tout en tournant la cape 3 par rapport à ladite capsule et audit flacon, une pression radiale sur la patte 33 de la cape 3. Dans ces conditions, au cours de la rotation sus-visée, la saillie 36 est projetée vers l'intérieur par suite de la déformation appliquée à la patte 33 qui la porte et est déplacée verticalement par suite de la coopération des dents 42 et 37; elle va donc à un moment donné se trouver à la hauteur de la cloison 48 et elle s'engagera dans le renfoncement 46 de la capsule (voir fig. 4) jusqu'à porter contre la butée 47 dudit renfoncement. La capsule est alors entraînée en rotation au dévissage.To obtain the unscrewing of this capsule and the opening of the bottle, the user must exercise, while turning the cap 3 relative to said capsule and to said bottle, a radial pressure on the tab 33 of the cap 3. Under these conditions, during the above-mentioned rotation, the projection 36 is thrown inward as a result of the deformation applied to the tab 33 which carries it and is moved vertically as a result of the cooperation of the teeth 42 and 37; it will therefore at a given moment be at the height of the partition 48 and it will engage in the recess 46 of the capsule (see fig. 4) until it bears against the stop 47 of said recess. The capsule is then rotated when unscrewing.

Fig. 4 fait bien ressortir qu'une fois la saillie 36 engagée au-dessus de la cloison 48, le rebord 49 s'oppose à tout retrait intempestif de ladite saillie, de telle sorte que l'actionnement est maintenu même lorsque l'utilisateur relâche sa pression radiale sur la patte déformable 33 avant que le dévissage ne soit achevé.Fig. 4 makes it clear that once the projection 36 engaged above the partition 48, the flange 49 opposes any untimely withdrawal of said projection, so that the actuation is maintained even when the user releases his radial pressure on the deformable tab 33 before the unscrewing is completed.

Il va de soi qu'on peut prévoir sur la cape extérieure 3 et sur la capsule 4 plusieurs renfoncements 32, respectivement 46, d'ailleurs en nombre égaux ou différents. De la même manière le nombre des dents 37 et 42 peut être absolument quelconque.It goes without saying that one can provide on the outer cap 3 and on the capsule 4 several recesses 32, respectively 46, moreover in equal or different numbers. In the same way the number of teeth 37 and 42 can be absolutely arbitrary.

On conçoit en particulier que l'un au moins des filetages 11 et 45 est susceptible d'être prévu de manière discontinue, sous la forme d'une série de saillies obliques. On comprend en outre que le bouchon suivant l'invention (en fait la capsule d'obturation 4) peut être avantageusement équipé dans sa partie inférieure d'une bande de garantie de tout type connu, apte à authentifier le contenu initial du flacon par déchirage lors de la première ouverture de celui-ci.It is understood in particular that at least one of the threads 11 and 45 may be provided discontinuously, in the form of a series of oblique projections. It is further understood that the stopper according to the invention (in fact the closure cap 4) can advantageously be equipped in its lower part with a guarantee strip of any known type, capable of authenticating the initial content of the bottle by tearing the first time you open it.
