Definitions

  • the invention relates to a cap according to the preamble of claim 1.
  • This cap is particularly intended to serve as a spray head for a spray.
  • the diffusers generally consist of a bottle provided with an aerosol valve and a cap provided with a push button for actuating the valve of the bottle.
  • a cap is provided on the base of the cap to hide the spray head. This cap is attached to the base by a hinge. Means are provided to keep the cap folded against the base, thus making the push button inaccessible.
  • a cap provided on the cap, opposite the hinge, allows by exerting pressure upwards to open the cap.
  • the means for retaining the cap are too flexible, it may open too easily, even when this is not desirable. If on the contrary they are too rigid, the user may have difficulty lifting the cap with the cap and may damage the nails.
  • the cap as unlocking means has the disadvantage of overtaking the envelope of the base. It may be hooked during storage or transport, for example in a toilet bag or in a purse, and the cap may inadvertently open into the bag at the risk of seeing the contents of the bottle s to spread there.
  • Document JP 2004352307 A discloses a cap comprising a base and a cap attached to the base by a hinge.
  • the cap may be retained in the closed position by hooks on the base and cooperating with recesses made in the cap.
  • the base is provided with a nozzle and the cap of a sealing cylinder intended to cover the nozzle when the cap is folded down.
  • a flexible blade whose one end is fixed to the nozzle and the other end bears against the cylinder of nozzle cover.
  • This flexible blade has many disadvantages. For example, if the cap is too folded in the open position, the end of the blade which bears against the sealing cylinder may deviate from it and not return to its place during the closure of the cap.
  • JP 2003054601 discloses a device to be placed on a drink can.
  • the upper part, to be fixed on the face of the bobbin provided with the opening, is provided with a base, a cap connected to the base by a hinge and means for holding the cap in the closed position.
  • a straw mounted spring To facilitate the opening of the cap when the unlocking means are actuated, there is provided a straw mounted spring.
  • One end of the straw plunges into the bobbin while the other end bears against a curved insert fixed in the center of the cap when the latter is in the closed position.
  • These means for lifting the cap are particularly complicated and involve many parts. They are far too expensive to be used on a single-use vial.
  • this spring straw is supported on the front face of the base.
  • This device for lifting the cap could therefore not be used with a spray cap. Indeed, this straw would be supported on the push button and trigger the spraying as the cap is closed, which is contrary to the desired effect. Another disadvantage lies in the fact that the end of the straw that must enter the mouth of the user, and which therefore keeps leftover drinks and saliva, bears against the bottom of the cap. Finally, here again, the unlocking means protrude from the envelope of the base and may therefore be actuated inadvertently during transport or storage.
  • Document JP 0914251 1 discloses a cap provided with a base, a cap and means for holding the cap in the closed position.
  • two Vertical spring blades on the base near the hinge and on the other hand two ribs inside the cap in front of the spring blades.
  • the ribs come to rest on the flat spring blades and bend.
  • these blades spring form a single piece with the cap and are made of the same material as the rest of said cap.
  • these blades are made of the same material as the base, usually polypropylene (PP) or polyethylene (PE). In all cases, these materials have no shape memory and irreversibly deform if they undergo such bending.
  • the means for lifting the cap proposed by this document can not work more than once or twice, the blades do not return to their initial vertical position after being kept bent.
  • the spring blades have a necessarily reduced length which greatly limits their effectiveness.
  • the unlocking means protrude completely from the base and may therefore be actuated inadvertently.
  • the object of the invention is to facilitate the opening of the cap using means to lift that do not have the disadvantages mentioned above.
  • Another object of the invention is to provide unlocking means which can not be operated inadvertently during transport or storage.
  • the means for lifting the cap are constituted by at least one spring blade whose one end is fixed to the base and whose other end can slide on the bottom of the cap, the spring blade is in the extended position when the cap is folded and relaxed or partially relaxed position when the cap is in the open position.
  • the second end of the blade slides on the bottom of the cap, the blade can be relatively long and therefore does not need to be as bent as in the state of the art.

Ce capuchon est particulièrement destiné à servir de tête de pulvérisation pour un spray.The invention relates to a cap according to the preamble of claim 1. This cap is particularly intended to serve as a spray head for a spray.
Les diffuseurs sont constitués en général d'un flacon muni d'une valve aérosol et d'un capuchon muni d'un bouton-poussoir pour actionner la valve du flacon. Afin d'éviter que le bouton poussoir ne soit actionné par inadvertance, il est courant de prévoir des moyens de blocage du bouton-poussoir. Une autre solution consiste à ne le rendre accessible qu'au moment de l'utilisation. Pour cela, une calotte est prévue sur la base du capuchon pour dissimuler la tête de pulvérisation. Cette calotte est fixée à la base par une charnière. Des moyens sont prévus pour maintenir la calotte rabattue contre la base, rendant ainsi le bouton-poussoir inaccessible. Une casquette prévue sur la calotte, à l'opposé de la charnière, permet en exerçant une pression vers le haut d'ouvrir la calotte.The diffusers generally consist of a bottle provided with an aerosol valve and a cap provided with a push button for actuating the valve of the bottle. In order to prevent the push button from being actuated inadvertently, it is common to provide means for blocking the push button. Another solution is to make it accessible only at the time of use. For this, a cap is provided on the base of the cap to hide the spray head. This cap is attached to the base by a hinge. Means are provided to keep the cap folded against the base, thus making the push button inaccessible. A cap provided on the cap, opposite the hinge, allows by exerting pressure upwards to open the cap.
Si les moyens pour retenir la calotte sont trop souples, celle-ci risque de s'ouvrir trop facilement, même lorsque cela n'est pas souhaitable. Si au contraire ils sont trop rigides, l'utilisateur risque d'avoir du mal à soulever la calotte à l'aide de la casquette et risque de s'abîmer les ongles.If the means for retaining the cap are too flexible, it may open too easily, even when this is not desirable. If on the contrary they are too rigid, the user may have difficulty lifting the cap with the cap and may damage the nails.
La casquette comme moyens de déverrouillage a pour inconvénient de dépasses de l'enveloppe de la base. Elle risque donc d'être accrochée lors du stockage ou du transport, par exemple dans une trousse de toilette ou dans un sac à main, et la calotte risque de s'ouvrir par inadvertance dans le sac au risque de voir le contenu du flacon s'y répandre.The cap as unlocking means has the disadvantage of overtaking the envelope of the base. It may be hooked during storage or transport, for example in a toilet bag or in a purse, and the cap may inadvertently open into the bag at the risk of seeing the contents of the bottle s to spread there.
On connaît du document JP 2004352307 A un capuchon comprenant une base et une calotte fixée sur la base par une charnière. La calotte peut être retenue en position fermée par des crochets situés sur la base et coopérant avec des évidements réalisés dans la calotte. La base est munie d'un gicleur et la calotte d'un cylindre d'étanchéité destiné à recouvrir le gicleur lorsque la calotte est rabattue. Pour faciliter l'ouverture de la calotte lorsque les moyens de fermeture sont déverrouillés, on a prévu une lame souple dont l'une des extrémités est fixée au gicleur et l'autre extrémité prend appui contre le cylindre de recouvrement du gicleur. Cette lame souple a de nombreux inconvénients. Par exemple, si la calotte est trop rabattue en position ouverte, l'extrémité de la lame qui prend appui contre le cylindre d'étanchéité risque de s'écarter de celui-ci et de ne pas retourner à sa place lors de la fermeture de la calotte. Pour éviter ce problème, il serait possible de donner à la lame une longueur suffisante pour qu'elle reste toujours en contact avec ce cylindre, mais dans ce cas, elle risque de ne plus pouvoir se replier correctement dans l'espace fermé situé entre la base et la calotte refermée. Un autre inconvénient vient du fait qu'en position fermée, cette lame est pratiquement entièrement repliée sur elle-même. Une telle lame ne pourrait pas être utilisée pour un flacon pressurisé, car elle risquerait d'appuyer sur le bouton poussoir lorsque la calotte est refermée et ainsi maintenir la valve ouverte durant toute la fermeture de la calotte, ce qui bien évidemment est le contraire de l'effet recherché. Enfin, ici encore, les moyens de déverrouillage dépassent de l'enveloppe du capuchon et risquent d'être actionnés par accident lors du stockage.Document JP 2004352307 A discloses a cap comprising a base and a cap attached to the base by a hinge. The cap may be retained in the closed position by hooks on the base and cooperating with recesses made in the cap. The base is provided with a nozzle and the cap of a sealing cylinder intended to cover the nozzle when the cap is folded down. To facilitate the opening of the cap when the closing means are unlocked, there is provided a flexible blade whose one end is fixed to the nozzle and the other end bears against the cylinder of nozzle cover. This flexible blade has many disadvantages. For example, if the cap is too folded in the open position, the end of the blade which bears against the sealing cylinder may deviate from it and not return to its place during the closure of the cap. To avoid this problem, it would be possible to give the blade a sufficient length so that it always remains in contact with this cylinder, but in this case, it may not be able to fold correctly in the closed space between the base and the cap closed. Another disadvantage comes from the fact that in the closed position, this blade is almost completely folded on itself. Such a blade could not be used for a pressurized bottle, because it could press the push button when the cap is closed and thus keep the valve open during the entire closure of the cap, which of course is the opposite of the desired effect. Finally, here again, the unlocking means protrude from the envelope of the cap and may be actuated accidentally during storage.
Le document JP 2003054601 divulgue un dispositif à placer sur une canette de boisson. La partie supérieure, à fixer sur la face de la canette munie de l'ouverture, est munie d'une base, d'une calotte reliée à la base par une charnière et de moyens pour maintenir la calotte en position fermée. Pour faciliter l'ouverture de la calotte lorsque les moyens de déverrouillage sont actionnés, on a prévu une paille montée sur ressort. L'une des extrémités de la paille plonge dans la canette tandis que l'autre extrémité prend appui contre un insert bombé fixé au centre de la calotte lorsque celle-ci est en position fermée. Ces moyens pour soulever la calotte sont particulièrement compliqués et font appel à de nombreuses pièces. Ils sont beaucoup trop coûteux pour être employés sur un flacon à usage unique. De plus, cette paille sur ressort prend appui sur la face frontale de la base. Ce dispositif pour soulever la calotte ne pourrait donc pas être utilisé avec un capuchon pour pulvérisateur. En effet, cette paille prendrait appui sur le bouton poussoir et déclencherait la pulvérisation tant que la calotte est fermée, ce qui est contraire à l'effet recherché. Un autre inconvénient réside dans le fait que l'extrémité de la paille qui doit entrer dans la bouche de l'utilisateur, et qui par conséquent conserve des restes de boissons et de salive, prend appui contre le fond de la calotte. Enfin, ici encore, les moyens de déverrouillage dépassent de l'enveloppe de la base et risquent donc d'être actionnés par mégarde lors du transport ou du stockage.JP 2003054601 discloses a device to be placed on a drink can. The upper part, to be fixed on the face of the bobbin provided with the opening, is provided with a base, a cap connected to the base by a hinge and means for holding the cap in the closed position. To facilitate the opening of the cap when the unlocking means are actuated, there is provided a straw mounted spring. One end of the straw plunges into the bobbin while the other end bears against a curved insert fixed in the center of the cap when the latter is in the closed position. These means for lifting the cap are particularly complicated and involve many parts. They are far too expensive to be used on a single-use vial. In addition, this spring straw is supported on the front face of the base. This device for lifting the cap could therefore not be used with a spray cap. Indeed, this straw would be supported on the push button and trigger the spraying as the cap is closed, which is contrary to the desired effect. Another disadvantage lies in the fact that the end of the straw that must enter the mouth of the user, and which therefore keeps leftover drinks and saliva, bears against the bottom of the cap. Finally, here again, the unlocking means protrude from the envelope of the base and may therefore be actuated inadvertently during transport or storage.
On connaît du document JP 0914251 1 un capuchon muni d'une base, d'une calotte et de moyens pour maintenir la calotte en position fermée. De plus, on a prévu d'une part deux lames ressort verticales sur la base près de la charnière et d'autre part deux nervures à l'intérieur de la calotte en face des lames ressort. Lorsque la calotte est rabattue sur la base, les nervures viennent s'appuyer sur le plat des lames ressort et les cintrent. Cependant, on voit sur l'une des coupes que ces lames ressort ne forment qu'une seule pièce avec le capuchon et sont réalisées dans le même matériau que le reste dudit capuchon. Autrement dit, ces lames sont fabriquées dans le même matériau que la base, en général du polypropylène (PP) ou du polyéthylène (PE). Dans tous les cas, ces matériaux n'ont pas de mémoire de forme et se déforment de façon irréversible si ont les soumet à un tel cintrage. Il en résulte que les moyens pour soulever la calotte proposés par ce document ne peuvent pas fonctionner plus d'une ou deux fois, les lames ne revenant pas dans leur position initiale verticale après avoir été maintenues cintrées. De plus, du fait de l'usage des nervures, les lames ressort ont une longueur nécessairement réduite ce qui limite grandement leur efficacité. Enfin, ici encore, les moyens de déverrouillage dépassent complètement de la base et risquent donc d'être actionnés par mégarde.Document JP 0914251 1 discloses a cap provided with a base, a cap and means for holding the cap in the closed position. In addition, two Vertical spring blades on the base near the hinge and on the other hand two ribs inside the cap in front of the spring blades. When the cap is folded on the base, the ribs come to rest on the flat spring blades and bend. However, it is seen on one of the sections that these blades spring form a single piece with the cap and are made of the same material as the rest of said cap. In other words, these blades are made of the same material as the base, usually polypropylene (PP) or polyethylene (PE). In all cases, these materials have no shape memory and irreversibly deform if they undergo such bending. As a result, the means for lifting the cap proposed by this document can not work more than once or twice, the blades do not return to their initial vertical position after being kept bent. In addition, because of the use of the ribs, the spring blades have a necessarily reduced length which greatly limits their effectiveness. Finally, here again, the unlocking means protrude completely from the base and may therefore be actuated inadvertently.
L'objectif de l'invention est de faciliter l'ouverture de la calotte à l'aide de moyens pour la soulever qui ne présentent pas les inconvénients évoqués précédemment. Un autre objectif de l'invention est de prévoir des moyens de déverrouillage qui ne risquent pas d'être actionnés par mégarde lors du transport ou du stockage.The object of the invention is to facilitate the opening of the cap using means to lift that do not have the disadvantages mentioned above. Another object of the invention is to provide unlocking means which can not be operated inadvertently during transport or storage.
Cet objectif est atteint conformément à l'invention du fait que les moyens pour soulever la calotte sont constitués par au moins une lame ressort dont l'une des extrémités est fixée à la base et dont l'autre extrémité peut glisser sur le fond de la calotte, la lame ressort étant en position tendue lorsque la calotte est rabattue et en position détendue ou partiellement détendue lorsque la calotte est en position grande ouverte. La deuxième extrémité de la lame ressort coulissant sur le fond de la calotte, la lame peut être relativement longue et donc n'a pas besoin d'être autant cintrée que dans l'état de la technique.This object is achieved according to the invention because the means for lifting the cap are constituted by at least one spring blade whose one end is fixed to the base and whose other end can slide on the bottom of the cap, the spring blade is in the extended position when the cap is folded and relaxed or partially relaxed position when the cap is in the open position. The second end of the blade slides on the bottom of the cap, the blade can be relatively long and therefore does not need to be as bent as in the state of the art.
Il est particulièrement avantageux que la ou les lames ressort soient réalisées dans un autre matériau que la base, la base étant réalisée de préférence dans du polypropylène (PP) ou du polyéthylène haute ou basse densité (PEHD, PEBD) et la ou les lames ressort de préférence dans une matière plastique à bonne mémoire de forme, telle que du polyoxyméthylène (POM), du polyamide (PA) ou du polypropylène téréphtalate (PPT). Ainsi, on choisira un premier matériau pour la base et la calotte qui sera relativement rigide (afin d'obtenir ou d'assurer un assemblage sécurisé entre la dite pièce et le flacon ou boîtier aérosol) dont les propriétés mécaniques seront adaptées pour la réalisation de la charnière. Pour les lames, au contraire, on choisira un matériau plus souple avec une bonne mémoire de forme.It is particularly advantageous for the spring leaf (s) to be made of a material other than the base, the base being preferably made of polypropylene (PP) or of high or low density polyethylene (HDPE, LDPE) and the leaf or blades preferably in a good shape memory plastic such as polyoxymethylene (POM), polyamide (PA) or polypropylene terephthalate (PPT). Thus, one will choose a first material for the base and the cap which will be relatively rigid (to obtain or ensure a secure connection between said part and the bottle or housing aerosol) whose mechanical properties will be adapted for the realization of the hinge. For blades, on the contrary, we will choose a softer material with a good shape memory.
Dans la pratique, la ou les lames ressort peuvent être surmoulées sur la base. Il est également possible que la ou les lames ressort soient des pièces distinctes de la base sur laquelle elles sont fixées par des moyens d'ancrage mécanique. Il peut s'agir par exemple de contre-dépouilles ou de joints d'accrochage.In practice, the leaf spring or blades can be overmolded on the base. It is also possible that the spring or blades is separate parts of the base on which they are fixed by mechanical anchoring means. It may be for example undercuts or seals.
Afin d'allonger encore la ou les lames ressort, il est préférable de fixer la ou les lames ressort dans la partie basse de la base opposée à la calotte, des fentes pouvant être réalisées dans la surface frontale de la base lorsque celle-ci est munie d'une telle surface frontale pour laisser passer la ou les lames ressort. Concrètement, la première extrémité est fixée sur la base en dessous de la surface frontale de la base, la lame passe à travers la fente et vient s'appuyer sur le fond de la calotte lorsque celle-ci est rabattue. La longueur des fentes est choisie de telle sorte que la lame peut se cintrer librement sans être gênée par la fente. Plus la lame est longue, meilleur est l'effet ressort et plus faible est la tension à laquelle elle est soumise lors de la fermeture de la calotte. En outre, plus la lame est longue, pus le contact entre celle-ci et la calotte est long, ce qui améliore le guidage de cette dernière. Il est possible aussi que les lames ressort passent de part et d'autre de la surface frontale de la base.In order to further lengthen the leaf spring or blades, it is preferable to fix the spring leaf or blades in the lower part of the base opposite the cap, slots that can be made in the front surface of the base when it is provided with such a front surface to let the leaf or blades spring. Concretely, the first end is fixed on the base below the front surface of the base, the blade passes through the slot and comes to rest on the bottom of the cap when it is folded. The length of the slots is chosen so that the blade can bend freely without being obstructed by the slot. The longer the blade, the better the spring effect and the lower the tension to which it is subjected when closing the cap. In addition, the longer the blade, the longer the contact between the latter and the cap, which improves the guiding of the latter. It is also possible that the spring blades pass on both sides of the front surface of the base.
Il est préférable de placer les moyens de déverrouillage dans la base ou dans la calotte de telle sorte à ne pas dépasser de l'enveloppe de celle-ci. Par enveloppe, on entend la surface géométrique virtuelle définie par la paroi extérieure de la base ou de la calotte en respectant la géométrie générale de celle-ci. Les moyens de déverrouillage sont donc placés de telle sorte qu'il ne dépasse pas l'emplacement qu'aurait la base ou la calotte s'ils n'avaient pas été présents.It is preferable to place the unlocking means in the base or in the cap so as not to exceed the envelope thereof. Envelope means the virtual geometric surface defined by the outer wall of the base or the cap respecting the general geometry thereof. The unlocking means are placed so that it does not exceed the location that would have the base or the cap if they had not been present.
Dans un mode de réalisation particulièrement avantageux, le premier et le second moyens de fermeture sont constitués d'un premier épaulement et d'un second épaulement, l'un des épaulements au moins étant placé sur un support présentant une certaine élasticité de sorte que lors du mouvement de rabat de la calotte, le support souple s'écarte perpendiculairement au mouvement d'approche des deux épaulements pour permettre le passage de l'autre épaulement jusqu'à ce que les deux épaulements s'encastrent l'un derrière l'autre permettant au support de retourner au moins partiellement dans sa position initiale.In a particularly advantageous embodiment, the first and the second closure means consist of a first shoulder and a second shoulder, at least one of the shoulders being placed on a support having a certain elasticity so that when of the flap movement of the cap, the flexible support deviates perpendicular to the approach movement of the two shoulders to allow the passage of the other shoulder until the two shoulders are embedded one behind the other allowing the support to return at least partially to its initial position.
Dans une première variante de réalisation de l'invention, les moyens de déverrouillage sont constitués par des moyens pour écarter parallèlement à la paroi de la base ou de la calotte l'un de l'autre le premier et le second moyens de fermeture.In a first embodiment of the invention, the unlocking means are constituted by means for spacing parallel to the wall of the base or the cap of one another the first and the second closure means.
Il est préférable que les moyens pour écarter parallèlement à la paroi de la base ou de la calotte les moyens de fermeture soient constitués par une plaque sur laquelle est fixée le premier ou le second moyen de fermeture, ladite plaque pouvant être déplacée par rapport à la base ou à la calotte selon un mouvement parallèle à la paroi de celle-ci entre une première position dans laquelle les deux moyens de fermeture coopèrent pour maintenir rabattue la calotte lorsque celle-ci est rabattue et une seconde position dans laquelle les deux moyens de fermeture ne coopèrent plus lorsque la calotte est rabattue, un ressort étant de préférence prévu pour ramener automatiquement la plaque, en l'absence d'efforts externes, dans la première position.It is preferable that the means for spacing parallel to the wall of the base or cap the closure means are constituted by a plate on which is fixed the first or the second closure means, said plate being movable relative to the base or the cap in a parallel movement to the wall thereof between a first position in which the two closure means cooperate to keep folded the cap when it is folded and a second position in which the two closure means no longer cooperate when the cap is folded down, a spring being preferably provided to automatically bring the plate, in the absence of external forces, in the first position.
Une solution pratique consiste à concevoir la plaque sous la forme d'une bague dont une section au moins est placée sur une partie au moins de la circonférence de la base, à l'extérieur de la zone couverte par la calotte lorsque celle-ci est rabattue, la bague pouvant coulisser contre la base, une partie de la bague pouvant remplir la fonction de ressort de rappel.A practical solution is to design the plate in the form of a ring of which at least a section is placed on at least part of the circumference of the base, outside the area covered by the cap when it is folded, the ring being slidable against the base, a part of the ring being able to fulfill the function of return spring.
Dans une seconde variante de réalisation de l'invention, les moyens de déverrouillage sont constitués par des moyens pour écarter perpendiculairement à la base ou à la calotte le premier et le second moyens de fermeture.In a second embodiment of the invention, the unlocking means are constituted by means for spacing the first and second closure means perpendicularly to the base or to the cap.
Pour cela, il est avantageux que les moyens d'écartement perpendiculaire soient constitués par des moyens pour exercer une pression sur la lame élastique depuis l'extérieur de la calotte.For this, it is advantageous that the perpendicular spacing means are constituted by means for exerting pressure on the elastic blade from outside the cap.
Il est conforme à l'invention de placer les moyens de déverrouillage sur une pièce rapportée placée sur la base ou sur la calotte. Dans une première version de cette seconde variante de réalisation, les moyens de fermeture et les moyens de déverrouillage sont placés à l'opposé de la charnière.It is according to the invention to place the unlocking means on an insert placed on the base or on the cap. In a first version of this second embodiment, the closing means and the unlocking means are placed opposite the hinge.
Dans une seconde version de cette seconde variante de réalisation, le capuchon est muni de deux jeux de moyens de fermeture et de moyens de déverrouillage placés de façon symétrique de part et d'autre du plan médian passant par le centre de la charnière.In a second version of this second embodiment, the cap is provided with two sets of closure means and unlocking means placed symmetrically on either side of the median plane passing through the center of the hinge.
Le capuchon conforme à l'invention est particulièrement bien adapté à un flacon pressurisé. Dans ce cas, il est muni d'un bouton poussoir placé sur base dans la zone pouvant être couverte par la calotte lorsqu'elle est rabattue, le bouton poussoir pouvant être muni de moyens pour actionner une valve située sur le récipient sur lequel le capuchon peut être placé, la base pouvant en outre comprendre un canal pour transmettre le produit sortant de la valve du récipient lorsqu'elle est actionnée par les moyens d'actionnement du bouton poussoir.The cap according to the invention is particularly well suited to a pressurized bottle. In this case, it is provided with a push button placed on a base in the area that can be covered by the cap when it is folded down, the push button being able to be provided with means for actuating a valve located on the container on which the cap may be placed, the base may further comprise a channel for transmitting the product exiting the valve of the container when actuated by the actuating means of the push button.

Les figures 1 à 1 1 présentent deux variantes d'un même exemple de réalisation. Ces deux variantes sont très semblables : la première est munie d'un seul jeu de moyens de fermeture et de moyens de déverrouillage, disposé sensiblement à l'opposé de la charnière, 15 tandis que la seconde est munie de deux jeux disposés de façon symétrique par rapport au plan médian passant par la charnière. Les figures 12 à 20 présentent un deuxième exemple de réalisation.Figures 1 to 1 1 show two variants of the same embodiment. These two variants are very similar: the first is provided with a single set of closure means and unlocking means disposed substantially opposite the hinge, while the second is provided with two sets arranged symmetrically. relative to the median plane passing through the hinge. Figures 12 to 20 show a second embodiment.
Le capuchon (10, 1 10, 210) est composé d'une base (20, 120, 220) et d'une calotte 20 (30, 130, 230) fixée à la base (20, 120, 220) par une charnière.The cap (10, 1, 10, 210) is composed of a base (20, 120, 220) and a cap (30, 130, 230) attached to the base (20, 120, 220) by a hinge .
Le capuchon est destiné à être placé sur le haut d'un récipient sous pression muni d'une valve aérosol (non représentée). Pour cela, des moyens de fixation (29, 129, 229) sont prévus sur la base (20, 120, 220).The cap is intended to be placed on the top of a pressure vessel provided with an aerosol valve (not shown). For this, fixing means (29, 129, 229) are provided on the base (20, 120, 220).
2525
La base (20, 120, 220) comprend essentiellement une partie sensiblement cylindrique (21 , 121 , 221 ) fermée sur le haut par un bouton-poussoir (22, 122, 222) formant la face frontale. Le bouton poussoir est muni de moyens (23, 123, 223) pour actionner la valve aérosol du récipient sur lequel sera monté le capuchon. Ces moyens d'actionnement (23, 30 123, 223) se poursuivent par un canal et une buse de pulvérisation (24, 124, 224). Le bouton poussoir (22, 122, 222) n'est relié au reste de la base (20, 120, 220) que par la languette (25, 125, 225) située du côté de la buse (24, 124, 224) de sorte qu'il est possible en exerçant une pression dessus de déplacer vers le bas les moyens d'actionnement (23, 123, 223) et ainsi d'actionner la valve.The base (20, 120, 220) essentially comprises a substantially cylindrical portion (21, 121, 221) closed at the top by a push button (22, 122, 222) forming the front face. The push button is provided with means (23, 123, 223) for actuating the aerosol valve of the container on which the cap will be mounted. These actuating means (23, 123, 223) are continued by a channel and a spray nozzle (24, 124, 224). The push button (22, 122, 222) is connected to the rest of the base (20, 120, 220) only by the tongue (25, 125, 225) located on the nozzle side (24, 124, 224) so that it is possible by exerting pressure on it to move down the actuating means (23, 123, 223) and thus to actuate the valve.
35 La calotte (30, 130, 230) est reliée à la base (20, 120, 220) par une charnière, ce qui lui permet de se déplacer entre une position entièrement rabattue sur la base (20, 120, 220), escamotant ainsi le bouton-poussoir (22, 122, 222), et une position grande ouverte dans laquelle l'utilisateur peut accéder à ce bouton poussoir (22, 122, 222). Cette charnière peut être conçue pour qu'elle ait elle-même un petit effet ressort de sorte que dès qu'un certain angle d'ouverture est atteint, elle tende à déplacer la calotte dans une position grande ouverte.35 The cap (30, 130, 230) is connected to the base (20, 120, 220) by a hinge, which allows it to move between a fully folded position on the base (20, 120, 220), thereby retracting the push button (22, 122, 222), and a wide open position in which the user can access this push button (22, 122, 222). This hinge can be designed so that it itself has a small spring effect so that as soon as a certain opening angle is reached, it tends to move the cap in a wide open position.
La base (20, 120, 220) et la calotte (30, 130, 230) sont réalisées par exemple dans du polypropylène (PP) ou du polyéthylène haute ou basse densité (PEHD, PEBD).The base (20, 120, 220) and the cap (30, 130, 230) are made for example in polypropylene (PP) or high or low density polyethylene (HDPE, LDPE).
Pour assurer une ouverture automatique de la calotte (30, 130, 230) dès que les moyens de déverrouillage sont actionnés, on a prévu deux lames ressort (32, 132, 232) dont l'une des extrémités est fixée sur la partie cylindrique (21 , 121 , 221 ) de la base et l'autre extrémité peut glisser sur la face interne de la calotte (30, 130, 230). Les lames ressort (32, 132, 232) passent de part et d'autre de la languette (25, 125, 225) reliant le bouton poussoir (22, 122, 222) à la base (20, 120, 220). Ces lames ressort (32, 132, 232) sont en position tendue lorsque la calotte (30, 130, 230) est rabattue sur la base (20, 120, 220) et en position détendue ou en tout cas moins tendue lorsque la calotte (30, 130, 230) est en position grande ouverte. En plaçant la première extrémité des lames ressort en dessous de la surface frontale (22, 122, 222), dans la partie basse de la base, on peut augmenter d'autant la longueur de la lame de sorte que celle-ci est encore plus efficace tout en étant soumise à des tensions moindres. Grâce aux fentes (26, 126), le bouton poussoir (22, 122) recouvre pratiquement toute la section transversale de la base (20, 120). Les fentes (26, 126) sont dimensionnées pour que les lames (32, 132) aient une grande liberté pour fléchir sous l'effet de la calotte qui se rabat.To ensure an automatic opening of the cap (30, 130, 230) as soon as the unlocking means are actuated, two spring blades (32, 132, 232) are provided whose one end is fixed on the cylindrical part ( 21, 121, 221) of the base and the other end can slide on the inner face of the cap (30, 130, 230). The spring blades (32, 132, 232) pass on both sides of the tongue (25, 125, 225) connecting the push button (22, 122, 222) to the base (20, 120, 220). These spring blades (32, 132, 232) are in the extended position when the cap (30, 130, 230) is folded over the base (20, 120, 220) and in the relaxed position or at least less tensioned when the cap (20, 120, 220) 30, 130, 230) is in the wide open position. By placing the first end of the spring blades below the front surface (22, 122, 222), in the lower part of the base, the length of the blade can be increased so that the latter is even more effective while being subject to lesser stresses. Through the slots (26, 126), the push button (22, 122) covers substantially the entire cross section of the base (20, 120). The slots (26, 126) are dimensioned so that the blades (32, 132) have great freedom to flex under the effect of the cap which folds.
Les lames (32, 132, 232) sont réalisées de préférence dans un matériau à bonne mémoire de forme, tel que du polyoxyméthylène (POM), du polyamide (PA) ou du polypropylène téréphtalate (PPT). Elles peuvent être surmoulées sur la base en faisant appel à des ancrage mécaniques (contre dépouilles ou joint d'ancrage) lorsque le matériau utilisé pour la base et celui utilisé pour les lames ne sont pas compatibles. Il est également possible que ces lames soient des pièces à part, distinctes de la base, et qu'elles soient fixées sur celle-ci par des moyens appropriés. Les lames glissant sur le fond de la calotte, elles ne risquent pas de perdre le contact avec un point d'appui particulier comme dans le document JP 2004352307. Même si elles perdent le contact avec le fond de la calotte lorsque celle-ci est grand ouverte, elles retrouveront le contact au point qu'elles avaient quitté lorsque la calotte sera rabattue. De plus, si jamais elles se déformaient un peu avec le temps, elles continueraient à entrer en contact avec le fond de la calotte en un point légèrement déplacé par rapport au point de contact initial.The blades (32, 132, 232) are preferably made of a good shape memory material, such as polyoxymethylene (POM), polyamide (PA) or polypropylene terephthalate (PPT). They can be overmolded on the base by using mechanical anchoring (against stripping or anchoring joint) when the material used for the base and that used for the blades are not compatible. It is also possible that these blades are separate parts, separate from the base, and they are fixed on it by appropriate means. The blades sliding on the bottom of the cap, they are not likely to lose contact with a particular fulcrum as in JP 2004352307. Even if they lose contact with the bottom of the cap when it is large open, they will find the contact to the point that they left when the cap will be folded. Moreover, if they ever deform a little with time, they would continue to come into contact with the bottom of the cap at a point slightly displaced from the initial point of contact.
Des moyens de fermeture sont prévus sur la calotte (30, 130, 230) et sur la base (20, 120, 220). Ils sont constitués par un premier épaulement (31 , 131 , 231 ) situé sur la face intérieure de la calotte (30, 130, 231 ) et par un deuxième épaulement (41 , 141 , 241 ) situé au niveau de la partie cylindrique (21 , 121 , 221 ) de la base (20, 120, 220).Closing means are provided on the cap (30, 130, 230) and on the base (20, 120, 220). They are constituted by a first shoulder (31, 131, 231) located on the inner face of the cap (30, 130, 231) and by a second shoulder (41, 141, 241) located at the cylindrical portion (21 , 121, 221) of the base (20, 120, 220).
Dans un premier mode de réalisation, ce deuxième épaulement (41 , 141 ) est placé sur une lame (40, 140) d'une certaine élasticité, légèrement inclinée par rapport au mouvement relatif du premier épaulement (31 , 131 ) lors de la fermeture de la calotte (30, 130). De plus, le ou les premiers épaulements (31 , 131 ) sont précédés d'une surface inclinée qui facilite encore l'entrée en contact de la partie de la calotte portant le premier épaulement (31 , 131 ) avec la partie de la lame (40, 140) portant le second épaulement (41 , 141 ). Ainsi, lorsque la calotte (30, 130) est rabattue sur la base (20, 120), la face inclinée précédant le premier épaulement (31 , 131 ) entre en contact avec la lame (40, 140), glisse contre celle-ci en l'écartant légèrement vers l'intérieur du capuchon (10, 1 10) jusqu'à ce que le premier épaulement (31 , 131 ) passe derrière le second épaulement (41 , 141 ), permettant à la lame (40, 140) de retourner dans sa position initiale, ou tout du moins de sans rapprocher. Dans cette position, il n'est plus possible d'ouvrir la calotte, les deux épaulements (31/41 , 131/141 ) coopérant ensemble. L'élasticité de la lame (40, 140) est choisie pour assurer une fermeture automatique de la calotte (30, 130) lorsque celle-ci est rabattue sur la base, sans offrir pour autant une résistance trop importante. Il va de soi que la surface inclinée peut être placée devant le premier épaulement et/ou devant le second épaulement.In a first embodiment, this second shoulder (41, 141) is placed on a blade (40, 140) of a certain elasticity, slightly inclined relative to the relative movement of the first shoulder (31, 131) during closure of the cap (30, 130). In addition, the first shoulder (s) (31, 131) are preceded by an inclined surface which further facilitates the contacting of the portion of the cap carrying the first shoulder (31, 131) with the portion of the blade ( 40, 140) carrying the second shoulder (41, 141). Thus, when the cap (30, 130) is folded over the base (20, 120), the inclined face preceding the first shoulder (31, 131) comes into contact with the blade (40, 140), slides against it by pulling it slightly inwardly of the cap (10, 1 10) until the first shoulder (31, 131) passes behind the second shoulder (41, 141), allowing the blade (40, 140) to return to its original position, or at least not closer. In this position, it is no longer possible to open the cap, the two shoulders (31/41, 131/141) cooperating together. The elasticity of the blade (40, 140) is chosen to ensure an automatic closure of the cap (30, 130) when it is folded on the base, without offering too much resistance. It goes without saying that the inclined surface can be placed in front of the first shoulder and / or in front of the second shoulder.
Dans sa partie opposée à l'épaulement (41 , 141 ), la lame (40, 140) est fixée à la partie cylindrique (21 , 121 ) de la base (20, 120). Il suffit donc pour libérer les deux épaulements (31/41 , 131/141 ) d'appuyer sur la lame pour écarter le deuxième épaulement (41 , 141 ) du premier épaulement (31 , 131 ) en lui appliquant un mouvement sensiblement perpendiculaire à la base, en direction du centre du capuchon. Dans les exemples présentés ici, les lames sont des pièces rapportées encastrées dans la base (20, 120). Il est également envisageable qu'elles ne fassent qu'une pièce avec la partie de la partie cylindrique (21 , 121 ) de la base en étant réalisées soit dans le même matériau soit dans un autre matériau par surmoulage. Dans un mode de réalisation particulier de l'invention, ces lames (40, 140) sont réalisées dans un matériau souple à bonne mémoire de forme, tel que du polyoxyméthylène (POM), du polyamide (PA) ou du polypropylène téréphtalate (PPT).In its opposite portion to the shoulder (41, 141), the blade (40, 140) is attached to the cylindrical portion (21, 121) of the base (20, 120). It is therefore sufficient to release the two shoulders (31/41, 131/141) to press the blade to spread the second shoulder (41, 141) of the first shoulder (31, 131) by applying a substantially perpendicular movement at the base, towards the center of the cap. In the examples presented here, the blades are inserts inset into the base (20, 120). It is also conceivable that they are only one piece with the portion of the cylindrical portion (21, 121) of the base being made either in the same material or in another material by overmolding. In a particular embodiment of the invention, these blades (40, 140) are made of a flexible material with good shape memory, such as polyoxymethylene (POM), polyamide (PA) or polypropylene terephthalate (PPT) .
Dans la première variante, le capuchon n'est muni que d'une seule lame (40) et d'un seul jeu d'épaulements (31 , 41 ). Cette lame (40) est située à l'opposé de la charnière de la calotte (30).In the first variant, the cap is provided with only one blade (40) and a single set of shoulders (31, 41). This blade (40) is located opposite the hinge of the cap (30).
Dans la seconde variante, le capuchon est muni de deux lames (140) portant chacune un épaulement (141 ), la calotte (130) comportant deux épaulements correspondants (131 ) sur sa face intérieure. Ces deux lames (140) et les épaulements correspondants (131 ) sont situés de façon symétrique par rapport au plan médian du capuchon passant par le centre de la charnière. Pour des raisons de stabilité, la partie cylindrique (121 ) de la base (120) recouvre partiellement les lames (140).In the second variant, the cap is provided with two blades (140) each carrying a shoulder (141), the cap (130) having two corresponding shoulders (131) on its inner face. These two blades (140) and the corresponding shoulders (131) are located symmetrically with respect to the median plane of the cap passing through the center of the hinge. For stability reasons, the cylindrical portion (121) of the base (120) partially overlaps the blades (140).
Comme on le voit, les moyens de fermeture (41 , 141 ) et les moyens de déverrouillageAs can be seen, the closing means (41, 141) and the unlocking means
(40, 140) reprennent leur position initiale dès que cesse la pression exercée sur les moyens de déverrouillage constitués par la ou les lames (40, 140).(40, 140) return to their initial position as soon as the pressure exerted on the unlocking means constituted by the blade or blades (40, 140) ceases.
Dès qu'une pression est exercée sur la ou les lames (40, 140), les deux épaulements cessent de coopérer et les deux lames ressort (32, 132) écartent la calotte (30, 130) de la base (20, 120) jusqu'à la position grande ouverte dans laquelle elle est maintenue par les lames ressort (32, 132). Lorsque que l'utilisateur rabat la calotte (30, 130) sur la base contre l'effet de ressort de la ou les lames ressort (32, 132), les épaulements (31/41 , 131/141 ) entrent en prise et retiennent la calotte (30, 130) en position rabattue.As soon as pressure is exerted on the blade (s) (40, 140), the two shoulders stop cooperating and the two spring blades (32, 132) separate the cap (30, 130) of the base (20, 120). to the wide open position in which it is held by the spring blades (32, 132). When the user folds the cap (30, 130) on the base against the spring effect of the spring blade or blades (32, 132), the shoulders (31/41, 131/141) engage and retain the cap (30, 130) in the folded position.
Dans un deuxième mode de réalisation (210), le ou les seconds épaulements (241 ) sont placés non pas sur une lame souple, mais sur une plaque (240) pouvant être déplacée tangentiellement à la base et parallèlement aux épaulements (231 , 241 ) jusqu'à ce que ceux-ci ne puissent plus coopérer ensemble. Dans l'exemple présenté ici, cette plaque est constituée d'une bague (240) entourant en partie la base (220) du capuchon (210) en dessous de la calotte (230) lorsqu'elle est en position rabattue. Vue de dessus, cette bague (240) a une forme annulaire dont une grande partie (242) s'appuie sur une partie de la circonférence de la base (220) et est toujours accessible par l'utilisateur. L'autre partie (243, 244) est sensiblement perpendiculaire au plan médian de la base passant par le milieu de la charnière et se trouve à l'intérieur du capuchon. Le centre (243) de cette partie intérieure est coincé dans une gorge tandis que ses extrémités (244) ne sont pas entravées et forment une zone de flexion permettant un petit mouvement circulaire de la bague (240) autour de sa position stable centrale. Ainsi, lorsque l'utilisateur fait glisser contre la base (220) la partie extérieure (242) de la bague (240) vers la droite ou vers la gauche selon un mouvement tangentiel à la base (220) et parallèle aux épaulements (231 , 241 ), il provoque le glissement des épaulements l'un sur l'autre. Grâce aux lames ressort (232), la calotte (230) se soulève dès que les deux épaulements (231 , 241 ) ne sont plus alignés. Après que l'utilisateur a relâché la bague (240), celle-ci revient automatiquement dans sa position centrale d'équilibre sous l'effet de ressort des zones extérieures (244) de la bague (240). Pour permettre une fermeture automatique de la calotte (230) lorsque l'utilisateur la rabat contre la base (220), il est prévu que la partie de la calotte (230) qui porte le premier épaulement (231 ) soit suffisamment souple pour s'écarter légèrement lorsque le premier épaulement (231 ) glisse contre l'appendice de la bague (240) qui porte le second épaulement (241 ), et ce, jusqu'à ce qu'il dépasse ce dernier et que les deux épaulements coopèrent à nouveau. Contrairement aux modes de réalisation précédents, ce n'est pas le support du second épaulement qui cède pour laisser passer le premier, mais le support du premier épaulement qui cède pour permettre le glissement des deux épaulements l'un vers l'autre. En effet, dans ce mode de réalisation, la bague est en appui contre la base, ce qui n'était pas le cas de l'extrémité des lames (40, 140) des exemples précédents.In a second embodiment (210), the one or the second shoulders (241) are placed not on a flexible blade, but on a plate (240) displaceable tangentially to the base and parallel to the shoulders (231, 241). until they can no longer cooperate together. In the example presented here, this plate consists of a ring (240) partially surrounding the base (220) of the cap (210) in below the cap (230) when in the folded position. Viewed from above, this ring (240) has an annular shape, a large portion (242) is supported on a portion of the circumference of the base (220) and is still accessible by the user. The other portion (243, 244) is substantially perpendicular to the median plane of the base passing through the middle of the hinge and is within the cap. The center (243) of this inner portion is wedged in a groove while its ends (244) are unobstructed and form a flexion zone allowing a small circular movement of the ring (240) around its central stable position. Thus, when the user slides against the base (220) the outer portion (242) of the ring (240) to the right or to the left in a movement tangential to the base (220) and parallel to the shoulders (231, 241), it causes the shoulders to slide on one another. With spring blades (232), the cap (230) rises as soon as the two shoulders (231, 241) are no longer aligned. After the user has released the ring (240), the ring automatically returns to its central equilibrium position under the spring effect of the outer zones (244) of the ring (240). To allow an automatic closing of the cap (230) when the user flap against the base (220), it is expected that the portion of the cap (230) which carries the first shoulder (231) is sufficiently flexible to s' move slightly apart when the first shoulder (231) slides against the appendage of the ring (240) carrying the second shoulder (241), until it protrudes beyond the latter and the two shoulders cooperate again . Unlike previous embodiments, it is not the support of the second shoulder that gives way to let the first, but the support of the first shoulder that gives way to allow the sliding of the two shoulders towards one another. Indeed, in this embodiment, the ring bears against the base, which was not the case of the end of the blades (40, 140) of the previous examples.
Dans les deux modes de réalisation, les moyens de déverrouillage, constitués par la ou les lames souples (40, 140) ou par l'anneau (240), sont toujours dans le prolongement de la paroi extérieure de la base de sorte qu'ils n'en dépassent pas. Il n'y a pas de discontinuité dans la forme géométrique de la base au passage des lames souples ou de l'anneau. Cela se voit particulièrement bien sur les vues en perspectives des figures 1 et 8 et sur les coupes des figures 1 1 , 16 et 20. Ces moyens de déverrouillage risquent moins d'être actionnés par mégarde lors du transport ou du stockage du produit. Ils ne risquent pas de s'accrocher à un objet saillant. Bien que les exemples présentés ou évoqués ici prévoient de mettre les moyens de déverrouillage (40, 140, 240) sur la base, il est tout à fait envisageable de les mettre sur la calotte. De même, les lames ressort (32, 132, 232) pourraient être fixées sur la calotte et glisser sur la surface intérieure de la base. On pourrait également prévoir tout autre système de ressort.In both embodiments, the unlocking means, constituted by the flexible blade or blades (40, 140) or by the ring (240), are always in the extension of the outer wall of the base so that they do not go beyond it. There is no discontinuity in the geometric shape of the base when passing the flexible blades or the ring. This is particularly seen in the perspective views of Figures 1 and 8 and the sections of Figures 1 1, 16 and 20. These unlocking means are less likely to be operated inadvertently during transport or storage of the product. They are not likely to cling to a projecting object. Although the examples presented or discussed here provide for putting the unlocking means (40, 140, 240) on the base, it is quite possible to put them on the cap. Similarly, the leaf spring (32, 132, 232) could be fixed on the cap and slide on the inner surface of the base. One could also provide any other spring system.
