Description

La présente demande concerne un flacon muni d'un embout réducteur et son application à la dispersion d'un liquide notamment visqueux.The present application relates to a bottle provided with a reducing end piece and to its application to the dispersion of a particularly viscous liquid.

De nombreux liquides, en fonction de leur utilisation, sont conditionnés en flacon et dispensés par l'intermédiaire d'un embout réducteur. Celui-ci permet de limiter le débit et la quantité de produit distribué à chaque utilisation. On peut citer par exemple les liquides servant à nettoyer les vitres ou la vaisselle ou les gels pour WC. En effet seules de relativement petites quantités sont utilisées à chaque fois. Par contre, les lessives liquides ou les nettoyants ménagers mettent en oeuvre des quantités importantes à chaque utilisation, de l'ordre de 50 ml et plus.Many liquids, depending on their use, are packaged in bottles and dispensed via a reducing nozzle. This makes it possible to limit the flow rate and the quantity of product dispensed for each use. Mention may be made, for example, of the liquids used for cleaning windows or dishes or gels for toilets. Indeed only relatively small amounts are used each time. On the other hand, liquid detergents or household cleaners use large quantities at each use, of the order of 50 ml and more.

L'embout réducteur permet également d'orienter plus ou moins précisément le jet de liquide vers l'endroit que l'on désire atteindre.The reducing nozzle also makes it possible to orient the jet of liquid more or less precisely towards the place which it is desired to reach.

Généralement ce jet est filaire ou cylindrique (diamètre 2 à 5 mm) et est donc d'une bonne précision, mais par contre il ne couvre pas une grande surface.Generally this jet is wired or cylindrical (diameter 2 to 5 mm) and is therefore of good precision, but on the other hand it does not cover a large area.

Dans un autre domaine, on connaît des buses de pulvérisation, notamment pour insecticides ou autres produits phytosanitaires, permettant un étalement en largeur d'une pulvérisation.In another field, spray nozzles are known, in particular for insecticides or other phytosanitary products, allowing spreading of a spray in width.

Les pulvérisateurs utilisés mettent en jeu une relativement forte pression, largement supérieure à celle que l'on atteint en appuyant sur le corps d'un flacon avec les doigts et la paume de la main ; de plus, ces buses comportent plusieurs pièces, dont la pièce terminale, par laquelle sort le jet de liquide, comprend un fin orifice situé au milieu d'une excavation allongée en forme de V. Enfin ces pulvérisateurs sont utilisables uniquement pour des liquides très fluides, de fluidité comparable à celle de l'eau.The sprayers used involve a relatively high pressure, much greater than that which is reached by pressing the body of a bottle with the fingers and the palm of the hand; in addition, these nozzles comprise several parts, the end part of which, through which the liquid jet exits, comprises a fine orifice situated in the middle of an elongated V-shaped excavation. Finally, these sprayers can only be used for very fluid liquids , fluidity comparable to that of water.

Dans le cas de certains produits tels qu'un gel pour appareils sanitaires tels les WC par exemple, il est nécessaire que la quasi-totalité d'une surface telle qu'une cuvette soit recouverte de produit.In the case of certain products such as a gel for sanitary appliances such as toilets for example, it is necessary that almost all of a surface such as a bowl is covered with product.

Il serait donc intéressant de disposer d'un flacon procurant un jet non plus filaire, mais en éventail, permettant, en un seul mouvement de couvrir une large surface.It would therefore be interesting to have a bottle providing a jet no longer wired, but in a fan, allowing, in a single movement to cover a large area.

Un tel embout devrait de plus être facile à réaliser, et économique, et de ce fait être réalisé d'une seule pièce.Such a tip should also be easy to make, and economical, and therefore be made in one piece.

On connaît enfin par US-A-1 696 506 et 2 837 251, GB-A-759 829 et CH-A-294 200 des tubes souples à presser remplis de produits très visqueux par exemple pâteux ou crémeux, tels que mayonnaise, pâte dentifrice ou crèmes cosmétiques, comportant un embout permettant d'étaler ou de donner une forme particulière au produit expulsé qui n'est pas projeté mais sort lentement de l'ouverture compte tenu de sa viscosité. En particulier, GB-A-759 829 décrit un tube pour délivrer une crème de rasage dans lequel la crème est délivrée au travers d'une étroite fente de sortie transversale.Finally, US-A-1,696,506 and 2,837,251, GB-A-759,829 and CH-A-294,200 disclose flexible press tubes filled with very viscous products, for example pasty or creamy, such as mayonnaise, dough toothpaste or cosmetic creams, comprising a nozzle making it possible to spread or to give a particular shape to the expelled product which is not projected but leaves the opening slowly taking into account its viscosity. In particular, GB-A-759 829 describes a tube for delivering a shaving cream in which the cream is delivered through a narrow transverse outlet slot.

C'est pourquoi la présente demande a pour objet un flacon muni d'un embout réducteur apte à contenir un liquide d'une viscosité faible ou moyenne à projeter sur une surface, caractérisé en ce que l'embout réducteur comprend un élément tubulaire dont l'extrémité est munie d'une ouverture en forme de fente par laquelle est projeté le liquide.This is why the present application relates to a bottle provided with a reducing nozzle capable of containing a liquid of low or medium viscosity to be sprayed onto a surface, characterized in that the reducing nozzle comprises a tubular element whose l the end is provided with a slot-shaped opening through which the liquid is projected.

La présente demande a plus particulièrement pour objet un flacon muni d'un embout réducteur caractérisé en ce que ledit flacon renferme un liquide d'une viscosité faible ou moyenne à projeter sur une surface, et en ce que l'embout réducteur comprend un élément tubulaire dont l'extrémité est munie d'une ouverture en forme de fente par laquelle est projeté le liquide.The present application more particularly relates to a bottle provided with a reducing nozzle characterized in that said bottle contains a liquid of low or medium viscosity to be sprayed onto a surface, and in that the reducing nozzle comprises a tubular element the end of which is provided with a slot-shaped opening through which the liquid is projected.

Par "embout", l'on entend la pièce d'un flacon disposée à l'ouverture de celui-ci. Cette pièce peut être monobloc avec le flacon, mais il s'agit habituellement, et de préférence, d'une pièce distincte, rapportée et adaptée à l'ouverture du flacon.By "tip" means the part of a bottle disposed at the opening thereof. This piece can be monobloc with the bottle, but it is usually, and preferably, a separate piece, attached and adapted to the opening of the bottle.

Par embout "réducteur", l'on entend que l'orifice de l'embout déterminant le débit du liquide est de dimension inférieure à celle de l'ouverture du flacon, la dimension déterminant le débit étant généralement le passage ayant la section la plus étroite.By "reducing" nozzle is meant that the orifice of the nozzle determining the flow of the liquid is of dimension smaller than that of the opening of the bottle, the dimension determining the flow being generally the passage having the most narrow.

Un tel embout est réalisé de préférence d'une seule pièce, par exemple par moulage. Il peut être disposé dans l'ouverture d'un flacon, par exemple par enfoncement, comme les autres embouts réducteurs bien connus, après remplissage du flacon, ou peut être intégré au flacon, l'ensemble flacon-embout étant réalisé par moulage.Such a tip is preferably made in one piece, for example by molding. It can be placed in the opening of a bottle, for example by sinking, like the other well-known reducing tips, after filling the bottle, or can be integrated into the bottle, the bottle-tip assembly being produced by molding.

Le flacon peut être tout flacon approprié, comprenant au moins une partie suffisamment souple pour être enfoncée par pression exercée par la main de l'utilisateur. De tels flacons sont bien connus et notamment conviennent ceux qui renferment habituellement des gels pour sanitaires ou des produits nettoyants pour la vaisselle ou pour les sols. Ces flacons, après pression, reprennent presque instantanément leur forme d'origine, et leur base, située du côté opposé à l'embout, est de préférence plane pour que le flacon tienne debout de lui-même. Ils se présentent généralement sous forme de bouteilles et les tubes sont exclus de la notion de flacon ci-dessus.The bottle can be any suitable bottle, comprising at least one part which is flexible enough to be pressed by pressure exerted by the hand of the user. Such bottles are well known and in particular are suitable for those which usually contain sanitary gels or cleaning products for dishes or for floors. These bottles, after pressure, return almost instantly to their original shape, and their base, located on the side opposite the nozzle, is preferably flat so that the bottle stands upright by itself. They are generally in the form of bottles and the tubes are excluded from the notion of bottle above.

Ces flacons ou bouteilles peuvent avoir par exemple une contenance de 150 ml, 200 ml, 1,5 litre, de préférence de 400 ml à 1 litre et plus particulièrement d'environ 750 ml.These flasks or bottles can for example have a capacity of 150 ml, 200 ml, 1.5 liters, preferably from 400 ml to 1 liter and more particularly about 750 ml.

Bien que l'embout de la présente invention convienne particulièrement aux liquides visqueux, à peu près inutilisables avec les embouts de l'art antérieur les plus proches, il convient également aux liquides plus fluides tels que les liquides ayant une fluidité analogue ou supérieure à celle de l'eau, ainsi qu'aux liquides de fluidité intermédiaire.Although the nozzle of the present invention is particularly suitable for viscous liquids, which are almost unusable with the closest prior art nozzles, it is also suitable for more fluid liquids such as liquids having a similar or greater fluidity than that water, as well as liquids of intermediate fluidity.

Ces liquides peuvent contenir des composés organiques ou minéraux et tout particulièrement un ou plusieurs composants tels que :

  • détergents (jusqu'à 50 %)
  • émulsifiants ou solubilisant de parfums (jusqu'à 10 %)
  • parfums (jusqu'à 10 %)
  • produits épaississants de toute nature, minérale tels que argiles, silices ou organique tels que tensioactifs, polymères ou végétale tels que les amidons, (jusqu'à 20 %)
  • désinfectants (jusqu'à 10 %)
  • acides (organiques ou minéraux) (jusqu'à 10 %)
  • colorants (jusqu'à 2 %)
  • conservateurs (jusqu'à 2 %) en solution de préférence aqueuse.
These liquids can contain organic or mineral compounds and very particularly one or several components such as:
  • detergents (up to 50%)
  • emulsifiers or solubilizers of perfumes (up to 10%)
  • fragrances (up to 10%)
  • thickening products of any kind, mineral such as clays, silicas or organic such as surfactants, polymers or vegetable such as starches, (up to 20%)
  • disinfectants (up to 10%)
  • acids (organic or mineral) (up to 10%)
  • dyes (up to 2%)
  • preservatives (up to 2%) in preferably aqueous solution.

Leur viscosité est faible ou moyenne et peut aller de préférence de 10 à 1000 mPa.s, notamment de 80 ou 100 à 1000 mPa.s, et tout particulièrement de 100 à 800 mPa.s, mesurée au viscomètre Brookfield RVT, mobile 2, vitesse 50 t/mn.Their viscosity is low or medium and can preferably range from 10 to 1000 mPa.s, in particular from 80 or 100 to 1000 mPa.s, and very particularly from 100 to 800 mPa.s, measured with the Brookfield RVT viscometer, mobile 2, speed 50 rpm.

La surface sur laquelle le liquide est projeté pourra être de toute nature, mais sera généralement et de préférence une surface dure, notamment des carrelages, des surfaces émaillées, mélaminées, des résines de synthèse, des surfaces de lavabo, cuvettes de toilettes, de baignoires, de bidets, d'urinoirs ... . La surface concernée sera généralement étendue, telle que la surface d'un élément sanitaire précité.The surface on which the liquid is sprayed may be of any kind, but will generally and preferably be a hard surface, in particular tiles, enameled, melamine-coated surfaces, synthetic resins, surfaces of washbasins, toilet bowls, bathtubs , bidets, urinals .... The surface concerned will generally be extended, such as the surface of an aforementioned sanitary element.

L'embout du flacon de la présente invention est caractérisé par la présence d'un élément tubulaire, de section transversale quelconque, par exemple sensiblement ovale, carrée, rectangulaire, et de préférence circulaire comportant la fente. Cette section sera en général régulière, mais d'autres formes telles que conique, la fente étant ménagée à l'extrémité du cône, ou, et de préférence, conique et ensuite tubulaire sont possibles.The tip of the bottle of the present invention is characterized by the presence of a tubular element, of any cross section, for example substantially oval, square, rectangular, and preferably circular comprising the slot. This section will generally be regular, but other shapes such as conical, the slot being formed at the end of the cone, or, and preferably, conical and then tubular are possible.

L'extrémité de l'élément tubulaire est munie d'une ouverture en forme de fente, qui s'étend de préférence sur au moins un côté de l'élément tubulaire. La longueur de l'élément peut varier légèrement mais sera généralement de 5 à 25 mm, la longueur maximum étant déterminée par la souplesse ou la rigidité demandée à l'élément tubulaire, ainsi qu'aux possibilités de fermeture du flacon.The end of the tubular member is provided with a slit-shaped opening, which preferably extends over at least one side of the tubular member. The length of the element may vary slightly but will generally be from 5 to 25 mm, the maximum length being determined by the flexibility or rigidity required of the tubular element, as well as the possibilities of closing the bottle.

L'extrémité de l'élément tubulaire peut avoir une forme quelconque adaptée telle que celle d'un parallélépipède rectangle, mais est de préférence hémisphérique.The end of the tubular element can have any suitable shape such as that of a rectangular parallelepiped, but is preferably hemispherical.

La fente sera habituellement de forme droite, vue de face et de préférence sensiblement dans l'axe de la longueur de l'élément tubulaire, et donc de la circulation du liquide.The slot will usually be straight in shape, seen from the front and preferably substantially in the axis of the length of the tubular element, and therefore of the circulation of the liquid.

La longueur selon laquelle la fente s'étend sur les côtés de l'élément tubulaire détermine la largeur de la projection du liquide.The length along which the slot extends over the sides of the tubular element determines the width of the projection of the liquid.

Des embouts préférés dont sont munis les flacons selon l'invention sont caractérisés en ce que la fente s'étend sur au moins un côté de l'élément tubulaire et de préférence au moins sur les côtés de l'élément tubulaire.Preferred tips with which the bottles according to the invention are provided are characterized in that the slot extends on at least one side of the tubular element and preferably at least on the sides of the tubular element.

Pour certains effets particuliers, l'extrémité peut renfermer plusieurs fentes, de préférence deux fentes, avantageusement en forme de croix.For certain particular effects, the end may contain several slots, preferably two slots, advantageously in the shape of a cross.

La présente demande a enfin pour objet l'application d'un flacon ci-dessus à la dispersion d'un liquide, notamment d'une viscosité faible ou moyenne, de préférence un liquide d'entretien ménager ou pour sanitaires tel qu'un gel pour sanitaires ainsi qu'un flacon tel que défini ci-dessus caractérisé en ce que ledit flacon renferme un liquide d'une viscosité faible ou moyenne à projeter sur une surface, qui est un liquide d'entretien ménager ou pour sanitaires.The present application finally relates to the application of a bottle above to the dispersion of a liquid, in particular of a low or medium viscosity, preferably a liquid for household or sanitary maintenance such as a gel for sanitary as well as a bottle as defined above characterized in that said bottle contains a liquid of low or medium viscosity to be sprayed onto a surface, which is a liquid for household cleaning or for sanitary.

La présente invention sera mieux comprise si l'on se réfère aux dessins dans lesquels :

  • Les figures 1 et 2 sont des vues en coupe d'embouts selon l'invention vus de face.
  • La figure 3 est une vue de face de l'embout de la figure 1, à 90° par rapport à la figure 1.
  • La figure 4 est une vue en coupe longitudinale d'un flacon 4 muni d'un embout selon l'invention, et partiellement rempli d'un liquide 5 de viscosité moyenne, à projeter.
The present invention will be better understood if reference is made to the drawings in which:
  • Figures 1 and 2 are sectional views of tips according to the invention seen from the front.
  • FIG. 3 is a front view of the endpiece of FIG. 1, at 90 ° relative to FIG. 1.
  • Figure 4 is a longitudinal sectional view a bottle 4 provided with a nozzle according to the invention, and partially filled with a liquid 5 of medium viscosity, to be sprayed.

Sur la figure 1, on distingue les éléments d'un embout réducteur classique à introduire dans l'orifice circulaire d'un flacon jusqu'au niveau de la butée circulaire d'arrêt 1. L'embout réducteur monobloc comprend un élément tubulaire 2 de forme complexe que l'on peut décomposer en trois parties : une partie inférieure conique, par laquelle arrive le liquide, prolongée par une partie cylindrique, elle même suivie d'une partie sensiblement hémisphérique. C'est dans cette partie hémisphérique que réside l'originalité de la présente invention : cette partie est verticalement fendue jusqu'au niveau de la partie cylindrique adjacente. Ici la fente 3 est droite et verticale, et à parois parallèles, écartées par exemple d'environ 0,7 mm. Le diamètre intérieur de la partie hémisphérique est d'environ 4 mm alors que le diamètre extérieur est de 6 mm environ (soit une épaisseur de matière, tel le polyéthylène basse densité, d'environ 1 mm). Les côtés de la fente suivent la forme hémisphérique de l'élément tubulaire ; elles pourraient avoir, si désiré, une forme de secteur.In FIG. 1, a distinction is made between the elements of a conventional reducing nozzle to be introduced into the circular orifice of a bottle up to the level of the circular stop stop 1. The monobloc reducing nozzle comprises a tubular element 2 of complex shape that can be broken down into three parts: a conical lower part, through which the liquid arrives, extended by a cylindrical part, itself followed by a substantially hemispherical part. It is in this hemispherical part that the originality of the present invention resides: this part is vertically split up to the level of the adjacent cylindrical part. Here the slot 3 is straight and vertical, and with parallel walls, spaced apart for example by about 0.7 mm. The internal diameter of the hemispherical part is approximately 4 mm while the external diameter is approximately 6 mm (or a thickness of material, such as low density polyethylene, of approximately 1 mm). The sides of the slot follow the hemispherical shape of the tubular element; they could have, if desired, a form of sector.

Par pression de la main sur un flacon en matière plastique souple rempli de liquide, on obtient un dispersion en bande large et régulière du produit formant un éventail régulier, permettant, par un mouvement de la main en arc de cercle, de couvrir rapidement et régulièrement une large surface.By hand pressure on a flexible plastic bottle filled with liquid, a wide and regular dispersion of the product is obtained, forming a regular fan, allowing, by movement of the hand in an arc, to cover quickly and regularly a large area.

La figure 2 est une figure analogue à celle de la figure 1, mais la partie terminale analogue à la partie hémisphérique ci-dessus, a une forme de cylindre bouché à angle droit. Il comporte aussi une fente 3, s'étendant jusqu'au bas de la partie cylindrique intermédiaire.Figure 2 is a figure similar to that of Figure 1, but the end portion similar to the hemispherical portion above, has the shape of a plugged cylinder at right angles. It also has a slot 3, extending to the bottom of the intermediate cylindrical part.

Selon la viscosité du liquide de remplissage, on peut avoir un jet en trident (avec un liquide de fluidité de l'ordre de celle de l'eau, à savoir de 10 à 20 mPa.s) ou en éventail régulier pour des liquides d'une viscosité de 100 à 800 mPa.s.Depending on the viscosity of the filling liquid, you can have a trident jet (with a liquid with a fluidity of the order of that of water, namely from 10 to 20 mPa.s) or by regular fan for liquids with a viscosity of 100 to 800 mPa.s.

Sur la figure 3, on distingue clairement la fente 3 de forme droite, aux côtés parallèles.In Figure 3, there is clearly a slot 3 of straight shape, with parallel sides.

Sur la figure 4, l'on distingue un flacon selon l'invention muni de l'embout réducteur de la figure 1.In FIG. 4, there is a bottle according to the invention provided with the reducing nozzle of FIG. 1.
