Description

La présente invention concerne un dispositif de conditionnement et d'application d'un produit selon le préambule de la revendication 1.The present invention relates to a device for packaging and applying a product according to the preamble of claim 1.

Par dispositif de conditionnement, on entend tout emballage qui permet la vente, le transport, la protection et le stockage du produit qu'il contient.Packaging device means any packaging that allows the sale, transport, protection and storage of the product it contains.

Par dispositif d'application, on entend tout dispositif comportant des moyens pour appliquer et étaler une composition, notamment cosmétique sur des matières kératiniques, telles que la peau ou des fibres kératiniques (cils, cheveux...)."Application device" means any device comprising means for applying and spreading a composition, in particular a cosmetic composition, on keratin materials, such as the skin or keratinous fibers (eyelashes, hair, etc.).

Il est connu, notamment du document FR 2 884 500 , de prévoir un piston coulissant dans le corps tubulaire d'un récipient destiné à recevoir un applicateur comportant un élément d'application disposé au bout d'une tige, afin que lors de l'introduction de l'applicateur, le piston tubulaire soit déplacé le long du corps de manière à comprimer le produit stocké dans le récipient. Le produit est ainsi confiné au fond du corps tubulaire et est maintenu en contact avec l'élément d'application, tout en étant séparé de l'air ambiant, ce qui favorise sa conservation.It is known, particularly from the document FR 2,884,500 , to provide a piston sliding in the tubular body of a container for receiving an applicator having an applicator element disposed at the end of a rod, so that during the introduction of the applicator, the tubular piston is moved along the body so as to compress the product stored in the container. The product is thus confined to the bottom of the tubular body and is kept in contact with the application element, while being separated from the ambient air, which promotes its preservation.

L'usage d'un tel piston est efficace en ce qui concerne le prélèvement du produit par l'applicateur et la conservation du produit. Toutefois, la circulation de la tige de l'applicateur au travers du piston et le déplacement de ce piston provoquent la création d'une surpression ou d'une dépression à l'intérieur du récipient, lesquelles conduisent à des efforts d'introduction ou d'extraction de l'applicateur relativement au récipient qui diffèrent suivant la position de l'applicateur le long de sa course d'introduction ou d'extraction. Ce phénomène, connu sous le nom de « pistonnage », est désagréable pour l'utilisateur et peut provoquer des bruits gênants. De plus, la résistance mécanique s'opposant au déplacement de l'applicateur par rapport au récipient est ressentie comme une gêne par l'utilisateur.The use of such a piston is effective with respect to the removal of the product by the applicator and the preservation of the product. However, the movement of the rod of the applicator through the piston and the displacement of this piston cause the creation of an overpressure or a depression inside the container, which lead to efforts of introduction or extraction of the applicator relative to the container which differ according to the position of the applicator along its introduction or extraction stroke. This phenomenon, known as "swabbing", is unpleasant for the user and can cause annoying noises. In addition, the mechanical resistance opposing the displacement of the applicator relative to the container is felt as an inconvenience by the user.

EP-A1-1714578 décrit un dispositif selon le préambule de la revendication 1. EP-A1-1714578 describes a device according to the preamble of claim 1.

L'invention a pour but de proposer une solution à cette non-homogénéité des efforts de retenue appliqués sur l'applicateur lors de sa course de déplacement.The object of the invention is to propose a solution to this non-homogeneity of the retaining forces applied to the applicator during its travel stroke.

A cet effet, l'invention a pour objet un dispositif de conditionnement et d'application selon la revendication 1.For this purpose, the subject of the invention is a packaging and application device according to claim 1.

Suivant des modes particuliers de réalisation, le dispositif de conditionnement et d'application comporte l'une ou plusieurs des caractéristiques des revendications 2 à 10.According to particular embodiments, the packaging and application device comprises one or more of the features of claims 2 to 10.

  • the figure 1 is a longitudinal sectional view of a packaging device according to the invention; and
  • the figure 2 is a perspective view on a larger scale of the abutment of the applicator resting on the sliding piston; and

  • the figure 6 is a perspective view of the stop of a variant of the packaging device according to the invention.

Le dispositif d'application et de conditionnement 10 illustré sur la figure 1 est, par exemple, destiné à contenir et permettre l'application de mascara ou de tout autre produit cosmétique visqueux. Il comporte un récipient 12 et un applicateur 14 qui, au repos, est maintenu vissé sur le récipient 12.The application and conditioning device 10 illustrated on the figure 1 is, for example, intended to contain and allow the application of mascara or other viscous cosmetic product. It comprises a container 12 and an applicator 14 which, at rest, is kept screwed on the container 12.

L'applicateur 14 comporte un bouchon 16 formant organe de préhension, prolongé par une tige 18 portant à une extrémité un élément d'application 20. La tige 18 et l'élément d'application 20 sont propres à être engagés dans le récipient 12, notamment dans la position de la figure 1.The applicator 14 comprises a plug 16 forming a gripping member, extended by a rod 18 carrying at one end an applicator element 20. The rod 18 and the applicator element 20 are adapted to be engaged in the container 12, particular in the position of the figure 1 .

Dans l'exemple considéré, l'élément d'application 20 comporte une brosse à mascara comportant une âme métallique torsadée et des poils retenus transversalement entre les spires de l'âme. En variante, l'élément d'application est un embout, floqué ou non, élastiquement déformable ou non, ou une mousse, ou un feutre, ou un pinceau ou une brosse sans âme métallique, par exemple une brosse ou un peigne réalisé par injection de matière plastique.In the example under consideration, the application element 20 comprises a mascara brush comprising a twisted metal core and retained bristles. transversely between the turns of the soul. Alternatively, the applicator element is a tip, flocked or not, elastically deformable or not, or a foam, or a felt, or a brush or brush without a metal core, for example a brush or a comb made by injection of plastic material.

Le récipient 12 comporte un corps tubulaire 22 de section transversale circulaire, présentant un tronçon principal 24 ouvert à une extrémité d'entrée. Au voisinage de cette entrée, il comporte extérieurement un filetage 26 propre à coopérer avec un taraudage 28 correspondant ménagé dans le bouchon 16 pour permettre une fermeture étanche du récipient par vissage du bouchon 16 sur le récipient 12.The container 12 comprises a tubular body 22 of circular cross section, having a main section 24 open at an inlet end. In the vicinity of this inlet, it has externally a thread 26 adapted to cooperate with a corresponding tapping 28 formed in the plug 16 to allow sealing of the container by screwing the plug 16 on the container 12.

A son autre extrémité, le tronçon principal 24 est prolongé par un puits 30 constitué d'un tronçon cylindrique borgne de section inférieure à celle du tronçon principal 24. Le puits 30 est obturé à une extrémité et est relié à son autre extrémité au tronçon principal 24 par un tronçon convergent 32. Le puits 30 présente une section intérieure sensiblement égale ou seulement légèrement supérieure à celle de l'élément d'application 20.At its other end, the main section 24 is extended by a well 30 consisting of a blind cylindrical section of lower section than that of the main section 24. The well 30 is closed at one end and is connected at its other end to the main section. 24 by a convergent section 32. The well 30 has an inner section substantially equal to or only slightly greater than that of the application element 20.

Le récipient comporte en outre un piston coulissant axialement 40 disposé à l'intérieur du tronçon principal 24 et guidé axialement par celui-ci. Le produit à appliquer est confiné dans le corps tubulaire 24 entre le piston 40 et le fond du puits 30.The container further comprises an axially sliding piston 40 disposed inside the main section 24 and axially guided by the latter. The product to be applied is confined in the tubular body 24 between the piston 40 and the bottom of the well 30.

Le piston 40 présente une ouverture axiale 42 de passage de l'élément d'application 20 et de la tige 18. La section de l'ouverture 42 est sensiblement égale à la section de la tige 18 dans sa partie courante.The piston 40 has an axial opening 42 through which the applicator element 20 and the stem 18 pass. The section of the opening 42 is substantially equal to the section of the rod 18 in its running part.

Le piston 40 comporte une virole extérieure 44 prolongée à chaque extrémité par deux lèvres divergentes 46, 48 s'appliquant de manière élastique sur la surface interne du tronçon principal 24, assurant ainsi l'étanchéité entre le piston 40 et le tronçon principal 24. La virole 44 est ainsi légèrement écartée du tronçon principal 24 dans la partie médiane du piston.The piston 40 has an outer shell 44 extended at each end by two diverging lips 46, 48 resiliently applied to the inner surface of the main section 24, thereby sealing the piston 40 and the main section 24. ferrule 44 is thus slightly spaced from the main section 24 in the middle part of the piston.

L'ouverture 42 est formée à l'extrémité rétrécie d'un tronçon de guidage généralement tronconique 50 du piston qui est relié à la virole 44 par son extrémité élargie tournée vers l'entrée du récipient. Ainsi, le tronçon de guidage 50 s'étend dans l'encombrement de la virole 44 sensiblement sur toute la longueur de celle-ci. Il présente une section circulaire généralement décroissante de son entrée de diamètre maximal tournée vers l'entrée du récipient jusqu'à l'ouverture 42.The opening 42 is formed at the narrowed end of a generally frustoconical guide section 50 of the piston which is connected to the shell 44 by its widened end turned towards the inlet of the container. Thus, the guide portion 50 extends in the bulk of the shell 44 substantially over the entire length thereof. It has a generally decreasing circular section of its maximum diameter inlet facing the inlet of the container to the opening 42.

Comme illustré sur la figure 3, le tronçon de guidage présente deux tronçons successifs avec des angles d'ouverture différents. Ainsi, le tronçon d'entrée opposé à l'ouverture 42 a un angle α d'inclinaison par rapport l'axe longitudinal de l'ordre de 45°, alors que le tronçon de sortie débouchant par l'ouverture 42 a un angle d'inclinaison β plus faible compris entre 20° et 40°.As illustrated on the figure 3 , the guide section has two successive sections with different opening angles. Thus, the inlet section opposite the opening 42 has an angle α of inclination with respect to the longitudinal axis of the order of 45 °, while the outlet section opening through the opening 42 has an angle d lower inclination β between 20 ° and 40 °.

L'ouverture 42 présente suivant sa périphérie un ensemble de cannelures régulièrement réparties propres à essuyer la surface de la tige 18 grâce aux surfaces supérieures des cannelures et à essorer l'élément d'application 20.The opening 42 has, along its periphery, a set of regularly distributed grooves which are suitable for wiping the surface of the rod 18 thanks to the upper surfaces of the grooves and to wring the applicator element 20.

Les cannelures 52 sont propres à assurer par ailleurs un écoulement de l'air entre la tige et le piston.The flutes 52 are adapted to ensure otherwise a flow of air between the rod and the piston.

Comme illustré sur la figure 3, la surface intérieure autour de l'ouverture 42 forme un épaulement interne 54 s'étendant vers l'intérieur. Les cannelures 52 sont définies par cet épaulement 54, de manière à s'étendre radialement vers l'ouverture 42.As illustrated on the figure 3 the inner surface around the opening 42 forms an inner shoulder 54 extending inwardly. The grooves 52 are defined by this shoulder 54, so as to extend radially towards the opening 42.

Le sommet des cannelures 52 et le sommet de cet épaulement 54 forment une zone d'appui tronconique 56 pour une butée axiale de l'élément d'application.The top of the flutes 52 and the top of this shoulder 54 form a frustoconical bearing zone 56 for an axial abutment of the applicator element.

Cette zone d'appui 56 forme un angle γ, compris entre 20 ° et 60 ° avec l'axe longitudinal du récipient.This bearing zone 56 forms an angle γ, between 20 ° and 60 ° with the longitudinal axis of the container.

A son extrémité portant l'élément d'application 20, la tige 18 présente une butée axiale 70 faisant saillie radialement par rapport à la partie courante notée 71 de la tige 18, suivant laquelle la section de la tige 18 est constante. Cette butée axiale est propre à prendre appui sur le piston 40 suivant le pourtour de l'ouverture 42 sur la zone d'appui 56 et plus généralement sur la surface intérieure du tronçon de guidage 50.At its end carrying the applicator element 20, the rod 18 has an axial stop 70 projecting radially from the running part denoted 71 of the rod 18, according to which the section of the rod 18 is constant. This axial abutment is adapted to bear on the piston 40 following the periphery of the opening 42 on the bearing zone 56 and more generally on the inner surface of the guide section 50.

La butée est formée d'un épanouissement radial 70 qui est escamotable radialement par déformation élastique radiale pour permettre le passage de la tige au travers du piston.The stop is formed of a radial expansion 70 which is retractable radially by radial elastic deformation to allow the passage of the rod through the piston.

Plus précisément, dans le mode de réalisation illustré aux figures, la butée axiale est formée d'un ensemble de pattes 72 prolongeant la tige 18 et séparées par des orifices 76 de passage d'air lorsque la butée est en appui sur la zone d'appui 56. Les pattes s'évasent depuis la tige 18 jusqu'à leurs extrémités libres 78 formant de points culminants radialement. A leurs extrémités libres, les pattes présentent un épaulement orienté vers l'élément d'application 20 propre à prendre appui sur la zone d'appui 56.More specifically, in the embodiment illustrated in the figures, the axial stop is formed of a set of tabs 72 extending the rod 18 and separated by orifices 76 of air passage when the stop bears on the area of support 56. The legs flare from the stem 18 to their free ends 78 forming radially apexes. At their free ends, the tabs have a shoulder oriented towards the application element 20 able to bear on the bearing zone 56.

Les pattes délimitent extérieurement une surface divergente radialement depuis la tige 18 jusqu'aux extrémités libres 78. Pour adoucir, la surface des extrémités libres 78 est chanfreinée ou arrondie.The tabs delimit externally a divergent surface radially from the rod 18 to the free ends 78. To soften, the surface of the free ends 78 is chamfered or rounded.

Les surfaces inclinées forment des surfaces propres à coopérer avec le pourtour de l'ouverture 42 sur la zone d'appui 56.The inclined surfaces form clean surfaces to cooperate with the periphery of the opening 42 on the bearing zone 56.

Les pattes 72 sont chacune déformables radialement et sont séparées par des encoches 82 formant les orifices de passage d'air 76. Les pattes 72 se déforment vers l'intérieur au contact de l'ouverture 42. Ces encoches 82 s'étendent au moins partiellement suivant la longueur de la tige et débouchent entre les extrémités 78 des pattes.The tabs 72 are each deformable radially and are separated by notches 82 forming the air passages 76. The tabs 72 deform inwardly in contact with the opening 42. These notches 82 extend at least partially following the length of the rod and open between the ends 78 of the tabs.

La tige présente dans sa partie courante une enveloppe tubulaire avec laquelle les pattes 72 sont venues de moulage et constituent des prolongements de celle-ci.The rod has in its running part a tubular envelope with which the tabs 72 are molded and are extensions of it.

Les pattes 72 ont une inclinaison par rapport à l'axe de la tige comprise entre 1 et 10 degrés, cette inclinaison étant inférieure à l'inclinaison du tronçon convergent 50 qui forme une surface de came propre à déformer les pattes 72 en coopérant avec l'extrémité libre 78 des pattes lors de l'enfoncement de l'applicateur dans le récipient.The tabs 72 have an inclination relative to the axis of the rod of between 1 and 10 degrees, this inclination being less than the inclination of the convergent section 50 which forms a cam surface capable of deforming the tabs 72 by cooperating with the free end 78 of the tabs during the insertion of the applicator into the container.

Les pattes 72 ont une longueur mesurée suivant l'axe de la tige comprise entre 1 et 5 mm. Leur largeur est sensiblement égale à la largeur des encoches 82.The tabs 72 have a length measured along the axis of the rod of between 1 and 5 mm. Their width is substantially equal to the width of the notches 82.

Les encoches ont une longueur, mesurée suivant l'axe de la tige, égale à celle des pattes et leur largeur est comprise entre 1 et 3 mm à leur extrémité débouchante.The notches have a length, measured along the axis of the rod, equal to that of the legs and their width is between 1 and 3 mm at their open end.

L'élasticité des pattes 72 et l'inclinaison de ces pattes ainsi que celle de la surface tronconique 50 sont telles que lorsque l'élément d'application 20 est introduit dans le récipient 12, l'effort nécessaire au passage de la butée escamotable 70 au travers de l'ouverture 42 est supérieur lors de l'introduction de l'applicateur à celui nécessaire pour ce même passage lors de l'extraction de l'applicateur.The elasticity of the tabs 72 and the inclination of these tabs as well as that of the frustoconical surface 50 are such that when the application element 20 is introduced into the container 12, the force required for the passage of the retractable stop 70 through the opening 42 is greater during the introduction of the applicator to that necessary for the same passage during the extraction of the applicator.

On conçoit que, initialement, l'élément d'application 20 est reçu dans le puits 30 du récipient.It will be appreciated that initially the applicator element 20 is received in the well 30 of the container.

Lorsque le récipient est plein, le piston est proche de l'entrée dans la position illustrée en traits mixtes sur la figure 1. Lorsqu'il est presque vide, le piston est enfoncé dans le tronçon principal 24 au voisinage du puits 30 comme illustré en traits continus sur la figure 1.When the container is full, the piston is close to the inlet in the position shown in phantom on the figure 1 . When it is almost empty, the piston is pushed into the main section 24 in the vicinity of the well 30 as illustrated in continuous lines on the figure 1 .

Pour l'utilisation de l'applicateur 14, celui-ci est extrait du récipient. La traction sur la tige 18 depuis l'organe de préhension 16 provoque la circulation de la tige 18 au travers de l'ouverture 42. Lors de cette circulation, la tige est essuyée par les cannelures ménagées sur le pourtour de l'ouverture 42. La présence des cannelures permet une circulation de l'air évitant tout effet de pistonnage. Les cannelures sont ensuite nettoyées lors du passage de la brosse.For the use of the applicator 14, it is extracted from the container. Pulling on the rod 18 from the gripping member 16 causes the rod 18 to flow through the opening 42. During this circulation, the rod is wiped by the grooves formed around the periphery of the opening 42. The presence of the grooves allows air circulation avoiding any effect of swabbing. The splines are then cleaned during the passage of the brush.

Le passage des pattes 72 au travers de l'ouverture 42 a lieu après celui de la tige. Du fait de leurs surfaces extérieures inclinées, les pattes se déforment radialement de sorte que leurs extrémités 78 se rapprochent de l'axe de la tige 18 permettant le franchissement de l'ouverture 42. Les poils ou autres organes de l'élément d'application se déforment élastiquement également pour passer au travers de l'ouverture 42. Lors de ce passage, ils subissent, du fait de la déformation, un essorage limitant la quantité de produit prélevé par l'élément d'application.The passage of the tabs 72 through the opening 42 takes place after that of the rod. Because of their inclined outer surfaces, the tabs deform radially so that their ends 78 are close to the axis of the rod 18 allowing the passage of the opening 42. The bristles or other organs of the application element also deform elastically to pass through the opening 42. During this passage, they undergo, due to the deformation, a spin limiting the amount of product taken by the application element.

Lorsque l'applicateur 14 après usage est réintroduit dans le récipient 12, l'élément d'application franchit l'ouverture 42 en se déformant puis les extrémités 78 des pattes viennent en appui sur la surface convergente 50 comme illustré sur la figure 2. En fonction de l'élasticité des pattes 72, les pattes se déforment et descendent jusqu'à venir en butée contre la zone d'appui 56. Elles provoquent alors le déplacement du piston 40 sous l'action de la poussée de la tige conduisant ainsi à la compression du produit contenu dans le récipient en aval du piston.When the applicator 14 after use is reintroduced into the container 12, the applicator element passes through the opening 42 by deforming and then the ends 78 of the tabs bear against the convergent surface 50 as shown in FIG. figure 2 . Depending on the elasticity of the tabs 72, the tabs deform and descend until they abut against the bearing zone 56. They then cause the piston 40 to move under the action of the thrust of the rod thus causing compressing the product contained in the container downstream of the piston.

Lorsque l'effort appliqué sur la tige 18 est supérieur à l'effort de réaction appliqué par le produit sur le piston et aux forces de frottement du piston sur le corps, les pattes 72 se compriment radialement, leurs extrémités 78 étant guidées par la zone d'appui 56 de la surface convergente 50 constituant une surface de came. Cette déformation autorise le franchissement de l'ouverture 42 par la butée 70 ainsi escamotée comme illustré sur la figure 4. Le déplacement de l'applicateur se prolonge alors après retour en forme des pattes 72, comme illustré sur la figure 5, par coulissement de la tige 18 au travers de l'ouverture 42 sans déplacement supplémentaire du piston, ceci jusqu'à ce que l'élément d'application 20 soit logé dans le puits 30 et que le bouchon soit vissé à l'extrémité ouverte du récipient.When the force applied on the rod 18 is greater than the reaction force applied by the product on the piston and the friction forces of the piston on the body, the tabs 72 compress radially, their ends 78 being guided by the zone bearing 56 of the convergent surface 50 constituting a cam surface. This deformation authorizes the crossing of the opening 42 by the stop 70 thus retracted as illustrated on the figure 4 . The displacement of the applicator then extends after return to the shape of the tabs 72, as shown in FIG. figure 5 by sliding the rod 18 through the opening 42 without further displacement of the piston, until the application member 20 is housed in the well 30 and the cap is screwed to the open end of the container.

On conçoit que lors du déplacement du piston, et lors du franchissement du piston par la butée escamotable 70, les pressions de part et d'autres du piston 40 s'équilibrent du fait de la circulation de l'air au travers des larges encoches 82.It is conceivable that during the displacement of the piston, and during the crossing of the piston by the retractable stop 70, the pressures on either side of the piston 40 are balanced due to the circulation of air through the wide notches 82 .

Les éventuelles différences de pression pouvant conduire à des sensations désagréables sont ainsi évitées.Any pressure differences that may lead to unpleasant sensations are thus avoided.

Une variante de dispositif d'application et de conditionnement 10 est illustrée par la figure 6.An alternative device for application and packaging 10 is illustrated by the figure 6 .

A la différence du dispositif représenté sur les figures 1 à 5, les pattes 72 de la butée axiale 70 présentent extérieurement une forme bombée de convexité dirigée à l'écart de l'axe de la tige 18.Unlike the device shown on the Figures 1 to 5 , the tabs 72 of the axial abutment 70 have an outwardly convexity curved shape directed away from the axis of the rod 18.

Chaque patte 77 converge radialement vers l'axe de la tige 18 à son extrémité libre 78.Each tab 77 converges radially toward the axis of the rod 18 at its free end 78.

Ainsi, la surface extérieure de chaque patte 72 comprend une première région 100 liée à la partie courante 71 de la tige 18, qui diverge radialement depuis la partie courante 71 de la tige 18 et une deuxième région 102 de contact avec le piston 40 qui converge vers l'axe de la tige 18.Thus, the outer surface of each tab 72 comprises a first region 100 connected to the running portion 71 of the rod 18, which diverges radially from the running portion 71 of the rod 18 and a second region 102 of contact with the piston 40 which converges towards the axis of the stem 18.

La longueur de la deuxième région convergente 102, prise le long de l'axe de la tige 18, est supérieure à au moins 10% de la longueur de la première région divergente 100.The length of the second convergent region 102, taken along the axis of the rod 18, is greater than at least 10% of the length of the first diverging region 100.

Lors de l'insertion de l'applicateur 14 dans le récipient 12, la région convergente 102 des pattes 72 accoste en premier sur la zone d'appui de la surface convergente 50, ce qui produit un contact plus doux avec le piston 40.Upon insertion of the applicator 14 into the container 12, the converging region 102 of the tabs 72 first lands on the bearing area of the converging surface 50, which produces a smoother contact with the piston 40.

Ainsi, le risque d'abîmer le piston 40 lors de la réinsertion de l'applicateur 14 est diminué.Thus, the risk of damaging the piston 40 during reinsertion of the applicator 14 is decreased.
