Definitions
- the present invention relates to the field of cleaning surfaces and more particularly sponges.
- the sponges according to the present invention have the advantage of optimizing the performance and the amount of detergent liquid used during cleaning by directly impregnating the inside of the sponge.
- the user can easily reload the sponge during the cleaning phase while dosing the amount of liquid applied.
- dish cleaning In the case of dish cleaning in particular, the cleaning is done in a container or more commonly under running water. Indeed, where stagnant water containing dishwashing liquid gets dirty quickly and hinders cleaning, many users prefer to wash dishes under running water. However, this type of cleaning requires the regular application of dishwashing liquid.
- the amount of foam created also depends on the structure of the sponge. This foam is the visual indicator for the user of the presence of product in the sponge and therefore of the cleaning power. Thus, the less the creation of foam, the more the user is encouraged to replenish the sponge with detergent product.
- One known type of sponge consists of a single absorbent layer. When the user has the detergent product on the sponge, it partially penetrates inside the sponge since it is only impregnated on the surface, that is to say over a small thickness of the sponge. 'sponge.
- Another known type of sponge is the so-called "multilayer” sponge.
- This type of sponge has several layers stacked on top of each other. The layers can be made of different materials to increase the versatility of the sponge.
- a so-called “bilayer” sponge composed of an absorbent layer stacked with a scouring or abrasive layer.
- Such sponges are marketed, for example, under the trademark Scotch Brite®.
- tri-layer composed of an absorbent layer arranged between upper and lower layers which may have additional functions, for example scouring and / or abrasive, cleaning or wiping.
- dish sponge comprising an ergonomic sleeve filled with detergent liquid fixed to the upper face of the sponge which continuously supplies the sponge with detergent liquid.
- dish sponge comprising an ergonomic sleeve filled with detergent liquid fixed to the upper face of the sponge which continuously supplies the sponge with detergent liquid.
- such products are marketed under the Dawn® brand.
- the continuous supply permanently saturates the sponge and also leads to unacceptable overconsumption of product.
- This type of product has furthermore, the drawback of limiting the cleaning surface available on the surface where the sleeve is bonded. More particularly, this type of sponge has the additional drawback of being very expensive and difficult to produce. Now, it is desirable that the maintenance products be as cheap as possible and easier to produce since they are intended to be replaced regularly.

- the sponges according to the present invention therefore remain particularly useful despite the presence of the orifices.
- the user now has the possibility of recharging the sponge with a sufficient quantity of cleaning liquid to clean the dishes without any waste or overconsumption.
- Using the sponge to clean several surfaces or dishwashing items between two refills avoids permanently saturating the sponge and offers real savings in dishwashing liquid.
- the sponge according to the invention generates a significant foam, distributed over all the available surfaces of the sponge, and not in a localized manner, which allows the user to visually verify that there is still detergent liquid capable of clean the surface or items to be washed. Thus, there is no incentive to regularly reload the sponge or to add liquid to the washing medium.

Description
La présente invention concerne le domaine du nettoyage des surfaces et plus particulièrement des éponges. Les éponges selon la présente invention ont l'avantage d'optimiser les performances et la quantité de liquide détergent utilisée lors du nettoyage en imprégnant directement l'intérieur de l'éponge. En outre, l'utilisateur peut aisément recharger l'éponge pendant la phase de nettoyage tout en dosant la quantité de liquide appliquée.The present invention relates to the field of cleaning surfaces and more particularly sponges. The sponges according to the present invention have the advantage of optimizing the performance and the amount of detergent liquid used during cleaning by directly impregnating the inside of the sponge. In addition, the user can easily reload the sponge during the cleaning phase while dosing the amount of liquid applied.
Il est connu d'utiliser une éponge associée à un produit détergent pour le nettoyage de surfaces, telles que des sols, des vitres ou bien des articles de cuisine et de vaisselle.It is known to use a sponge combined with a detergent product for cleaning surfaces, such as floors, windows or else kitchenware and crockery.
Dans le cas du nettoyage de vaisselle particulièrement, le nettoyage se fait dans un bac ou plus couramment sous l'eau courante. En effet, là où une eau stagnante contenant le liquide vaisselle se salit rapidement et gêne le nettoyage, beaucoup d'utilisateurs préfèrent la vaisselle sous l'eau courante. Toutefois, ce type de nettoyage nécessite l'application régulière de liquide vaisselle.In the case of dish cleaning in particular, the cleaning is done in a container or more commonly under running water. Indeed, where stagnant water containing dishwashing liquid gets dirty quickly and hinders cleaning, many users prefer to wash dishes under running water. However, this type of cleaning requires the regular application of dishwashing liquid.
Lors de la phase de nettoyage, il existe une technique dite « d'application directe » consistant à déposer le produit détergent directement sur la vaisselle à nettoyer ou bien sur la face de l'éponge qui sera en contact avec les articles de vaisselle avant de les nettoyer. La porosité de l'éponge permet de retenir une partie du liquide détergent dans l'éponge. Toutefois il est fréquent qu'une quantité substantielle de liquide détergent soit perdue avant d'être utilisée. En outre l'absorption du liquide détergent dans l'éponge dépend du matériau de l'éponge.During the cleaning phase, there is a so-called "direct application" technique consisting of depositing the detergent product directly on the dishes to be cleaned or else on the face of the sponge which will be in contact with the dishes before washing. clean them. The porosity of the sponge helps to retain some of the detergent liquid in the sponge. However, it is often the case that a substantial amount of detergent liquid is lost before it is used. Also the absorption of the detergent liquid in the sponge depends on the material of the sponge.
La pression exercée par l'utilisateur sur l'éponge humidifiée, combinée à la porosité de l'éponge, entraine la création de mousse. La quantité de mousse créée dépend également de la structure de l'éponge. Cette mousse est le repère visuel pour l'utilisateur de la présence de produit dans l'éponge et donc du pouvoir nettoyant. Ainsi, moins la création de mousse est importante, plus l'utilisateur est incité à réapprovisionner l'éponge en produit détergent.The pressure exerted by the user on the moistened sponge, combined with the porosity of the sponge, causes the creation of foam. The amount of foam created also depends on the structure of the sponge. This foam is the visual indicator for the user of the presence of product in the sponge and therefore of the cleaning power. Thus, the less the creation of foam, the more the user is encouraged to replenish the sponge with detergent product.
Un surdosage du produit détergent par l'utilisateur peut ainsi se produire. La structure de l'éponge est donc un facteur important de la consommation de produit détergent par l'utilisateur.An overdose of the detergent product by the user can thus occur. The structure of the sponge is therefore an important factor in the consumption of detergent product by the user.
Un type connu d'éponge est composé d'une unique couche absorbante. Lorsque l'utilisateur dispose du produit détergent sur l'éponge, celui-ci pénètre partiellement à l'intérieur de l'éponge puisqu'elle n'est imprégnée qu'en surface, c'est-à-dire sur une faible épaisseur d'éponge.One known type of sponge consists of a single absorbent layer. When the user has the detergent product on the sponge, it partially penetrates inside the sponge since it is only impregnated on the surface, that is to say over a small thickness of the sponge. 'sponge.
Après une courte utilisation, notamment sous l'eau courante, le produit détergent est épuisé, la création de mousse devient faible et l'utilisateur est rapidement incité à réapprovisionner l'éponge. Ce type d'éponge entraine donc une surconsommation non satisfaisante de produit détergent.After a short use, in particular under running water, the detergent product is used up, the creation of foam becomes weak and the user is quickly encouraged to replenish the sponge. This type of sponge therefore leads to unsatisfactory overconsumption of detergent product.
Un autre type connu d'éponge est l'éponge dite « multicouche ». Ce type d'éponge comporte plusieurs couches empilées les unes au-dessus des autres. Les couches peuvent être composées de matériaux différents pour augmenter la polyvalence de l'éponge. Ainsi, il existe une éponge dite « bicouche » composée d'une couche absorbante empilée avec une couche récurante ou abrasive. De telles éponges sont commercialisées par exemple sous la marque Scotch Brite®.Another known type of sponge is the so-called "multilayer" sponge. This type of sponge has several layers stacked on top of each other. The layers can be made of different materials to increase the versatility of the sponge. Thus, there is a so-called "bilayer" sponge composed of an absorbent layer stacked with a scouring or abrasive layer. Such sponges are marketed, for example, under the trademark Scotch Brite®.
Il existe également une éponge dite « tri couche » composée d'une couche absorbante disposée entre des couches supérieure et inférieure pouvant avoir des fonctions complémentaires par exemple récurante et/ou abrasive, nettoyante ou essuyante.There is also a so-called “tri-layer” sponge composed of an absorbent layer arranged between upper and lower layers which may have additional functions, for example scouring and / or abrasive, cleaning or wiping.
Cependant, il est fréquent que les utilisateurs réapprovisionnant une éponge «multicouche», appliquent le liquide détergent directement sur la surface destinée à être en contact avec la surface à nettoyer, c'est-à-dire la couche abrasive ou récurante avant de poursuivre le nettoyage. Or, les couches abrasives ou récurantes présentent une porosité faible, voire inexistante ce qui limite d'autant la pénétration du produit détergent dans l'éponge. Cela entraine l'élimination d'une grande partie du produit lorsque l'éponge est mise au contact d'eau, notamment lorsqu'elle est utilisée sous l'eau courante, et entraine également une surconsommation importante de liquide détergent.However, it is common for users replenishing a "multi-layer" sponge, apply the detergent liquid directly to the surface intended to be in contact with the surface to be cleaned, that is to say the abrasive or scouring layer before continuing the cleaning. cleaning. However, the abrasive or scouring layers have low porosity, or even no porosity, which accordingly limits the penetration of the detergent product into the sponge. This leads to the elimination of a large part of the product when the sponge is brought into contact with water, in particular when it is used under running water, and also leads to a significant overconsumption of detergent liquid.
Il existe par ailleurs dans l'art antérieur un autre type d'éponge vaisselle comportant un manchon ergonomique rempli de liquide détergent fixé sur la face supérieure de l'éponge qui approvisionne en continu l'éponge en liquide détergent. Par exemple, de tels produits sont commercialisés sous la marque Dawn® Cependant, l'approvisionnement continu sature l'éponge en permanence et entraine également une surconsommation non acceptable de produit. Ce type de produits a en outre l'inconvénient de limiter la surface nettoyante disponible sur la surface où est collé le manchon. Plus particulièrement, ce type d'éponge présente l'inconvénient supplémentaire d'être très coûteux et difficile à réaliser. Or, il est souhaitable que les produits d'entretien soient le moins cher possible et plus faciles à réaliser puisqu'ils sont destinés à être remplacés régulièrement.There is also in the prior art another type of dish sponge comprising an ergonomic sleeve filled with detergent liquid fixed to the upper face of the sponge which continuously supplies the sponge with detergent liquid. For example, such products are marketed under the Dawn® brand. However, the continuous supply permanently saturates the sponge and also leads to unacceptable overconsumption of product. This type of product has furthermore, the drawback of limiting the cleaning surface available on the surface where the sleeve is bonded. More particularly, this type of sponge has the additional drawback of being very expensive and difficult to produce. Now, it is desirable that the maintenance products be as cheap as possible and easier to produce since they are intended to be replaced regularly.
Parmi ce type d'éponge, certains comportent un trou traversant vertical permettant à une partie du liquide détergent du manchon d'être appliquée directement sur la vaisselle à nettoyer et sur la partie récurante. Il en résulte donc les mêmes inconvénients qu'avec l'utilisation des éponges multicouches.Among this type of sponge, some have a vertical through hole allowing part of the detergent liquid from the sleeve to be applied directly to the dishes to be cleaned and to the scouring part. This therefore results in the same drawbacks as with the use of multilayer sponges.

Selon la présente invention, le terme « liquide détergent » désigne tout liquide ou gels nettoyants pouvant être utilisé dans le nettoyage ou l'entretien de la maison. Il s'agit par exemple des liquides dégraissants, des détergents, des liquides vaisselles, des liquides contenant des enzymes, des antibactériens ou bien des antiseptiques. Le terme désigne également des gels qui, n'étant pas complètement solides, sont suffisamment fluides pour remplir une cavité, être absorbés par
l'éponge et être relargués lors de la phase de nettoyage, par exemple à l'aide d'une simple compression de l'éponge par l'utilisateur.According to the present invention, the term “detergent liquid” denotes any cleaning liquid or gels which can be used in cleaning or maintaining the house. These are, for example, degreasing liquids, detergents, dishwashing liquids, liquids containing enzymes, antibacterials or else antiseptics. The term also refers to gels which, not being completely solid, are sufficiently fluid to fill a cavity, to be absorbed by
sponge and be released during the cleaning phase, for example by simply compressing the sponge by the user.
Ces types de liquides/gels correspondent généralement à des produits concentrés en agent détergent ; ils possèdent généralement des viscosités typiquement comprises entre 10 et 10000 mPa.s (centipoises), par exemple entre 200 et 3000 mPa.s (centipoises) ou bien entre 300 et 2000 mPa.s (centipoises) à 25°C. Ainsi, les éponges selon la présente invention sont utilisables avec différents types de liquides actuellement commercialisés. Un type de liquide détergent standard de référence est le liquide vaisselle commercialisé sous la marque Fairy® ou encore Paic®.These types of liquids / gels generally correspond to products concentrated in detergent agent; they generally have viscosities typically between 10 and 10,000 mPa.s (centipoise), for example between 200 and 3,000 mPa.s (centipoise) or else between 300 and 2000 mPa.s (centipoise) at 25 ° C. Thus, the sponges according to the present invention can be used with various types of liquids currently on the market. A reference standard type of detergent liquid is dishwashing liquid sold under the Fairy® or Paic® brand.
Selon la présente invention, le terme « éponge » s'entend d'un matériau absorbant, poreux et/ou fibreux, naturel ou synthétique, utilisé pour le nettoyage de surface ou d'articles de vaisselle. Une éponge se présente généralement sous la forme d'un rectangle présentant deux faces principales nettoyantes et de quatre surfaces latérales. Les faces dites « principales » offrent les plus grandes surfaces de contact de toutes les faces de l'éponge Le terme désigne un article capable d'être directement manipulée par l'utilisateur. Généralement, les dimensions de l'éponge sont telles que l'utilisateur peut prendre l'éponge de pleine main. Une telle éponge peut également avoir une forme ergonomique, par exemple avoir un profil aminci en son centre de manière à offrir une meilleure prise en pain ou présenter des renfoncements latéraux adaptés pour faciliter la saisie de l'éponge par l'utilisateur. Notamment, selon un mode de réalisation préféré de l'invention, les éponges excluent la présence d'un manchon réservoir, capable de contenir un réservoir de liquide nettoyant.According to the present invention, the term “sponge” is understood to mean an absorbent, porous and / or fibrous material, natural or synthetic, used for cleaning a surface or for cleaning dishes. A sponge usually comes in the form of a rectangle with two main cleaning faces and four side surfaces. The so-called “main” faces offer the largest contact surfaces of all the faces of the sponge. The term designates an article capable of being directly handled by the user. Generally, the dimensions of the sponge are such that the user can take the sponge with the full hand. Such a sponge can also have an ergonomic shape, for example have a tapered profile in its center so as to offer better grip in the bar or have lateral recesses adapted to facilitate the grip of the sponge by the user. In particular, according to a preferred embodiment of the invention, the sponges exclude the presence of a reservoir sleeve, capable of containing a reservoir of cleaning liquid.
L'éponge selon l'invention permet l'introduction du liquide détergent à l'intérieur de l'éponge. En outre, l'éponge selon l'invention est susceptible d'être imprégnée par le liquide introduit, c'est-à-dire qu'elle permet à une quantité substantielle du liquide introduit dans la cavité de pénétrer directement à l'intérieur de la structure de l'éponge, c'est-à-dire d'être absorbée. Par substantielle, on entend au moins 10%, au moins 30%, au moins 50%, au moins 75% ou bien au moins 90% du volume de liquide introduit dans la cavité après que l'éponge ait été éventuellement humidifiée. Ainsi, le liquide se retrouve contenu dans la structure même de l'éponge et émane sous forme de mousse de l'ensemble des surfaces disponibles de l'éponge au cours du nettoyage. C'est toute la structure de l'éponge qui génère et favorise alors la formation de mousse.The sponge according to the invention allows the introduction of the detergent liquid inside the sponge. In addition, the sponge according to the invention is capable of being impregnated with the liquid introduced, that is to say it allows a substantial amount of the liquid introduced into the cavity to penetrate directly inside the cavity. the structure of the sponge, that is, to be absorbed. By substantial is meant at least 10%, at least 30%, at least 50%, at least 75% or else at least 90% of the volume of liquid introduced into the cavity after the sponge has optionally been moistened. Thus, the liquid is found contained in the very structure of the sponge and emanates in the form of foam from all the available surfaces of the sponge during cleaning. It is the entire structure of the sponge that generates and then promotes the formation of foam.
L'éponge selon l'invention permet en effet d'être imprégnée par le liquide avant que celui-ci ne ressorte de la cavité sous la pression de l'utilisateur. De façonThe sponge according to the invention in fact makes it possible to be impregnated with the liquid before the latter emerges from the cavity under the pressure of the user. In a way
avantageuse, l'éponge selon l'invention permet d'être imprégnée par le liquide introduit dans la cavité assez rapidement pour qu'il ne ressorte pas au cours d'une manipulation conventionnelle de l'éponge, c'est-à-dire en quelques minutes, par exemple en 5, 3 ou 2 minutes.advantageously, the sponge according to the invention makes it possible to be impregnated with the liquid introduced into the cavity quickly enough so that it does not come out during conventional handling of the sponge, that is to say in a few minutes, for example in 5, 3 or 2 minutes.
Les matériaux entrant dans la composition de l'éponge la rendant adaptée à imprégner le liquide introduit seront choisis par l'homme du métier selon l'utilisation envisagée et la nature du liquide à utiliser.The materials entering into the composition of the sponge making it suitable for impregnating the liquid introduced will be chosen by those skilled in the art according to the use envisaged and the nature of the liquid to be used.
En augmentant la diffusion du liquide dans l'éponge, l'efficacité des principes actifs et des additifs généralement compris dans la composition du liquide, tels que les enzymes, les bactéricides ou les parfums est améliorée.By increasing the diffusion of the liquid in the sponge, the effectiveness of the active principles and of the additives generally included in the composition of the liquid, such as enzymes, bactericides or perfumes is improved.
Typiquement, l'éponge présente une densité (poids volumique) comprise entre 18 et 40 kg/m3 et de façon préférée comprise entre 20 et 30 kg/m3. Elle peut être adaptée selon les utilisations envisagée. Une densité trop faible peut entrainer une rétention de liquide insuffisante tandis qu'une densité trop élevée peut altérer la souplesse ainsi que la génération de mousse.Typically, the sponge has a density (volumetric weight) of between 18 and 40 kg / m 3 and preferably of between 20 and 30 kg / m 3 . It can be adapted according to the envisaged uses. Too low a density can result in insufficient liquid retention while too high a density can impair flexibility as well as foam generation.
Le matériau poreux peut comporter des pores fermés, ou partiellement fermés, de préférence entre 2 et 20% et de manière encore préférée entre 3 et 5 % de pores fermés. En effet, une structure poreuse totalement ouverte - c'est-à-dire dont les pores sont ouverts- facilite l'absorption du produit vaisselle, mais n'en permet pas la rétention. Au contraire, une structure poreuse totalement fermée - c'est-à-dire dont tous les pores sont fermés - est étanche et rigide. Ainsi, une couche comportant une portion seulement de ses pores fermés ou partiellement fermés permet une imprégnation et une rétention satisfaisante du produit vaisselle pour une consommation économique de produit vaisselle.The porous material may have closed pores, or partially closed pores, preferably between 2 and 20% and more preferably between 3 and 5% closed pores. Indeed, a totally open porous structure - that is to say one of which the pores are open - facilitates the absorption of the washing-up liquid, but does not allow its retention. On the contrary, a totally closed porous structure - that is to say one of which all the pores are closed - is tight and rigid. Thus, a layer comprising only a portion of its closed or partially closed pores allows satisfactory impregnation and retention of the washing-up liquid for economical consumption of washing-up liquid.
De plus, une telle structure poreuse comportant seulement une portion de ses pores fermés ou partiellement fermés permet d'augmenter la création de mousse. Avantageusement l'éponge comportera notamment des pores d'un diamètre moyen inférieur à 1 mm pour améliorer son pouvoir moussant. La quantité de mousse formée peut être appréciée selon le protocole présenté dans les exemples ci-après.In addition, such a porous structure comprising only a portion of its closed or partially closed pores makes it possible to increase the creation of foam. Advantageously, the sponge will include in particular pores with an average diameter of less than 1 mm in order to improve its foaming power. The amount of foam formed can be assessed according to the protocol presented in the examples below.
Des structures d'éponge avantageuses selon l'invention offrent une grande capacité et vitesse d'absorption. Par exemple, la capacité d'absorption est telle qu'un volume de 2 ml d'un liquide présentant une viscosité de 900 mPa.s (centipoises) à une température de 25°C, déposé à la surface de l'éponge préalablement humidifiée, (2cm d'épaisseur et 70 cm2 de surface), est absorbé en moins de 5 minutes, de préférence en moins de 3 minutes et de façon encore préférée moins de 2 minutes.Advantageous sponge structures according to the invention offer high capacity and speed of absorption. For example, the absorption capacity is such that a volume of 2 ml of a liquid having a viscosity of 900 mPa.s (centipoise) at a temperature of 25 ° C, deposited on the surface of the previously moistened sponge. , (2cm thick and 70 cm 2 of surface), is absorbed in less than 5 minutes, preferably in less than 3 minutes and even more preferably in less than 2 minutes.
Le matériau peut également être hydrophile pour accélérer l'imprégnation du produit vaisselle dans l'éponge. Il peut être composé par exemple de mousse de polyuréthane hydrophile, de matériau alvéolaire à pores ouverts, matériau alvéolaire hydrophile, matériau alvéolaire à base d'un polymère d'acétate de vinyle, de matériau à base de cellulose, cette liste n'étant pas limitative.The material can also be hydrophilic to accelerate the impregnation of the washing-up liquid in the sponge. It may be composed, for example, of hydrophilic polyurethane foam, of open-pore cellular material, hydrophilic cellular material, cellular material based on a vinyl acetate polymer, of cellulose-based material, this list not being limiting.
Selon la présente invention, le terme de « cavité » s'entend de tout espace créé au sein de l'éponge susceptible d'être fabriqué par prélèvement de matière, tel qu'une entaille ou bien un trou. Par exemple, le prélèvement de matière peut se faire par forage, fraisage, incision ou bien par meulage. Plus particulièrement, la cavité est réalisée directement dans la masse de l'éponge et non par assemblage d'éléments dont une partie de la matière aurait été préalablement prélevée. Ainsi, les cavités sont préparées selon des procédés faciles à mettre en œuvre qui simplifient la fabrication industrielle des éponges par rapport à des formes de cavités plus complexes et permettent de diminuer leurs coûts de fabrication et donc leur prix. Les éponges selon l'invention comprennent une ou plusieurs cavités comme illustré dans les
Les cavités peuvent également avoir un fond, notamment dans le cas où l'une des cavités serait verticale par rapport à l'une des surfaces de nettoyage principales de l'éponge, de manière à ce que le liquide détergent puisse être absorbé au cœur de l'éponge par l'éponge et non directement libéré sur la surface à nettoyer, à travers l'éponge. Un fond n'est cependant pas nécessaire lorsqu'une cavité traversante est inclinée par rapport à l'axe vertical ou bien parallèle à l'une des surfaces principales de nettoyage. En effet, le liquide a alors la possibilité d'être absorbé dans le cœur de l'éponge en s'écoulant le long de la paroi de la cavité avant de ressortir.The cavities can also have a bottom, especially in the case where one of the cavities is vertical with respect to one of the main cleaning surfaces of the sponge, so that the detergent liquid can be absorbed in the heart of the sponge. sponge by the sponge and not directly released onto the surface to be cleaned, through the sponge. However, a bottom is not necessary when a through cavity is inclined relative to the vertical axis or else parallel to one of the main cleaning surfaces. Indeed, the liquid then has the possibility of being absorbed in the heart of the sponge by flowing along the wall of the cavity before coming out.
De façon avantageuse, la cavité des éponges selon l'invention comprend un fond. Typiquement, le volume intérieur de la cavité, ou, le cas échéant, le volume intérieur cumulé des cavités, est compris entre 1 et 6 cm3, de préférence entre 1,2 et 4 cm3, ou bien encore 1,2 et 2 cm3. Dans le cas d'une application pour la vaisselle, ce volume correspond typiquement à la demi-dose nécessaire pour une vaisselle standard, ce qui permet de réaliser un cycle de nettoyage avec une seule recharge. En remplissant la cavité, l'utilisateur dispose d'un repère visuel qui lui permet systématiquement de remplir l'éponge avec un volume constant de liquide détergent et de doser économiquement le produit lors de chaque recharge. De plus, la cavité permet d'introduire le liquide détergent directement dans le cœur de l'éponge ce qui permet de tirer profit des effets détergents et moussants de toute la quantité du produit ajouté sans qu'il n'y ait de perte. Tel n'était pas le cas avec les éponges de l'art antérieur, notamment lorsqu'elles étaient utilisées sous l'eau courante.Advantageously, the cavity of the sponges according to the invention comprises a bottom. Typically, the interior volume of the cavity, or, where appropriate, the cumulative interior volume of the cavities, is between 1 and 6 cm 3 , preferably between 1.2 and 4 cm 3 , or even 1.2 and 2 cm 3 . In the case of an application for dishes, this volume typically corresponds to the half-dose necessary for standard dishes, which makes it possible to carry out a cleaning cycle with a single refill. By filling the cavity, the user has a visual cue which allows him systematically to fill the sponge with a constant volume of detergent liquid and to economically dose the product during each refill. In addition, the cavity allows the detergent liquid to be introduced directly into the heart of the sponge, which makes it possible to take advantage of the detergent and foaming effects of the entire sponge. quantity of the product added without any loss. This was not the case with the sponges of the prior art, in particular when they were used under running water.
Il est également envisageable de prévoir un volume de cavité spécifique selon les propriétés d'un type de liquide détergent en particulier, par exemple en fonction de la concentration du liquide détergent ou bien de son pouvoir nettoyant pour une application donnée.It is also possible to envisage providing a specific cavity volume depending on the properties of a particular type of detergent liquid, for example depending on the concentration of the detergent liquid or else on its cleaning power for a given application.
La cavité débouche sur au moins une des surfaces de l'éponge. Typiquement, la taille et la forme de l'orifice correspondent à la section de la cavité traversante de façon à faciliter la fabrication des éponges de l'invention. L'orifice, comprend une surface typiquement comprise entre 5 et 200 mm2, de préférence comprise entre 20 et 120 mm2 et de façon encore préférée entre 50 et 120 mm2 ou encore entre 50 et 100 mm2 de manière à pouvoir accueillir directement l'embout de flacons de liquides nettoyants.The cavity opens onto at least one of the surfaces of the sponge. Typically, the size and shape of the orifice correspond to the section of the through cavity so as to facilitate the manufacture of the sponges of the invention. The orifice comprises a surface area typically between 5 and 200 mm 2 , preferably between 20 and 120 mm 2 and more preferably between 50 and 120 mm 2 or alternatively between 50 and 100 mm 2 so as to be able to receive directly the tip of cleaning fluid bottles.
Le contour de l'orifice sur la surface libre est tel que la distance maximale entre deux points du contour de l'orifice est comprise entre 3, de préférence 5, de préférence encore 8, et 20 mm, de préférence 15 mm, et de préférence encore 12 mm. En d'autres termes, sur l'ensemble des points du contour, la distance maximale entre deux points de ce contour est comprise entre 3 et 20 mm. De façon avantageuse, cette taille d'orifice évite que le liquide introduit dans la cavité par l'utilisateur ne ressorte avant qu'il n'ait imprégné l'intérieur de l'éponge.The contour of the orifice on the free surface is such that the maximum distance between two points of the contour of the orifice is between 3, preferably 5, more preferably 8, and 20 mm, preferably 15 mm, and more preferably 12 mm. In other words, on all the points of the contour, the maximum distance between two points of this contour is between 3 and 20 mm. Advantageously, this orifice size prevents the liquid introduced into the cavity by the user from coming out before it has impregnated the inside of the sponge.
De façon préférée, l'orifice possède une surface légèrement inférieure à la taille de l'embout du flacon de liquide nettoyant et se déforme lorsque le flacon est introduit dans l'orifice de manière à assurer un contact hermétique avec l'embout dudit flacon. Cette herméticité peut aussi être obtenue par pression de la tête du flacon sur la surface de l'éponge située autour de l'orifice. Cette variante de l'invention évite ainsi toute perte de produit détergent au moment de la recharge. L'utilisateur remplit la cavité en pressant sur le flacon et sait qu'il a rempli la cavité lorsqu'il sent une légère résistance sur le flacon.Preferably, the orifice has a surface slightly smaller than the size of the tip of the cleaning liquid bottle and deforms when the bottle is introduced into the orifice so as to ensure hermetic contact with the tip of said bottle. This hermeticity can also be obtained by pressing the head of the bottle on the surface of the sponge located around the orifice. This variant of the invention thus avoids any loss of detergent product when recharging. The user fills the cavity by squeezing the vial and knows that he has filled the cavity when he feels a slight resistance on the vial.
Compte tenu de la flexibilité de l'éponge, l'orifice, ainsi que la cavité, peuvent également être une entaille ou incision qui en se déformant permet l'introduction de l'embout d'un flacon de liquide au cœur de l'éponge, la déformation de la masse de l'éponge créant dans ce cas une cavité.Given the flexibility of the sponge, the orifice, as well as the cavity, can also be a notch or incision which, by deforming, allows the introduction of the tip of a bottle of liquid into the heart of the sponge. , the deformation of the mass of the sponge in this case creating a cavity.
Selon le nombre de cavité envisagé pour l'éponge, la ou les cavités peuvent déboucher sur l'une ou plusieurs des surfaces de l'éponge. Comme cela est illustré dans les figures, l'orifice peut déboucher sur une des surfaces de nettoyage de l'éponge pour faciliter son accès ou proposer une utilisation intuitive à l'utilisateur.Depending on the number of cavities envisaged for the sponge, the cavity or cavities may open onto one or more of the surfaces of the sponge. As shown in the figures, the orifice may open onto one of the cleaning surfaces of the sponge to facilitate its access or to offer intuitive use to the user.
Selon une mode de réalisation avantageux, un des orifices débouche sur une des faces latérales de l'éponge de manière à ce que l'utilisateur puisse recharger l'éponge en liquide avec une deuxième main et sans changer la prise de l'éponge avec la première main. Un orifice sur une des faces latérale permet également de positionner une cavité plus profonde ou traversante lorsqu'une utilisation spécifique est envisagée nécessitant un volume plus important de produit détergent, par exemple lors du nettoyage d'un four ou de casseroles. Ce mode de réalisation permet également de profiter de toute la surface de nettoyage des faces principales de l'éponge sans que celles-ci n'aient besoin d'être trouées. Le positionnement latéral de l'orifice confère en outre une meilleure résistance à l'éponge lors de son utilisation que s'il était situé sur l'une des faces nettoyantes.According to an advantageous embodiment, one of the orifices opens onto one of the lateral faces of the sponge so that the user can reload the sponge with liquid with a second hand and without changing the grip of the sponge with the first hand. An orifice on one of the side faces also makes it possible to position a deeper or through cavity when a specific use is envisaged requiring a larger volume of detergent product, for example when cleaning an oven or pots. This embodiment also makes it possible to take advantage of the entire cleaning surface of the main faces of the sponge without the latter needing to be perforated. The lateral positioning of the orifice also confers better resistance to the sponge during its use than if it were located on one of the cleaning faces.
D'autre, part, la forme du contour de l'orifice peut varier d'une éponge à l'autre. Elle est de préférence circulaire, mais peut également avoir une forme ovale ou bien encore rectangulaire. Elle peut également être une entaille ou une incision.On the other hand, the shape of the outline of the orifice may vary from one sponge to another. It is preferably circular, but can also have an oval or even rectangular shape. It can also be a notch or an incision.
Selon un autre mode de réalisation, l'éponge selon l'invention comprend plusieurs couches éventuellement réalisées dans un matériau différent de l'éponge principale. Ces couches supplémentaires peuvent être ajoutées par collage à l'éponge principale. Il est ainsi possible de multiplier les fonctionnalités de l'éponge finale, en y ajoutant par exemple, une face récurante capable de nettoyer les salissures incrustées, ou bien une face capable d'essuyer les surfaces etc...Typiquement, les éponges selon la présente invention peuvent être recouvertes sur au moins une des surfaces par une ou plusieurs couches supplémentaires. Selon un mode préféré de l'invention, l'éponge comprend une couche supplémentaire recouvrant l'une ou les deux surfaces principales de l'éponge.According to another embodiment, the sponge according to the invention comprises several layers optionally made of a material different from the main sponge. These additional layers can be added by gluing to the main sponge. It is thus possible to multiply the functions of the final sponge, by adding, for example, a scouring face capable of cleaning encrusted dirt, or a face capable of wiping the surfaces etc ... Typically, the sponges depending on the The present invention can be covered on at least one of the surfaces by one or more additional layers. According to a preferred embodiment of the invention, the sponge comprises an additional layer covering one or both main surfaces of the sponge.
Typiquement, des couches supplémentaires à base de matériaux cellulosiques, de tissus cellulosiques, de mousses de polyuréthane, de matériaux alvéolaires à pores ouverts, de matériaux alvéolaires hydrophiles, de matériaux alvéolaires à base d'un polymère d'acétate de vinyle, de matériaux à base de micro fibres ou en mélamine peuvent être utilisées. De tels matériaux sont connus de l'homme du métier et directement applicables dans la présente invention.Typically, additional layers based on cellulosic materials, cellulosic fabrics, polyurethane foams, open pore cellular materials, hydrophilic cellular materials, vinyl acetate polymer based cellular materials, materials with micro fibers or melamine base can be used. Such materials are known to those skilled in the art and directly applicable in the present invention.
Un mode de réalisation particulièrement préféré de l'invention concerne une éponge tri-couches, c'est-à-dire comprenant une couche supplémentaire sur chacune des surfaces principales de l'éponge lesquelles peuvent avoir des fonctions différentes, l'une abrasive et l'autre possédant des propriétés absorbantes ou dégraissantes. Les couches réalisées en matériau à base de microfibres sont notamment avantageuses pour leurs propriétés absorbantes et dégraissantes et/ou d'essuyage. Ce type de structure s'avère particulièrement efficace pour compléter la performance anti-graisse d'un liquide détergent et aide à éliminer certaines souillures sur des articles de vaisselle, telles que des traces de rouge à lèvre sur des verres. Les couches extérieures permettent également d'améliorer la rétention du liquide à l'intérieur de l'éponge, limitant d'avantage la perte de produit en cours d'utilisation tout en augmentant la production de mousse sur toutes les faces libres de l'éponge.A particularly preferred embodiment of the invention relates to a three-layer sponge, that is to say comprising an additional layer on each of the main surfaces of the sponge which may have different functions, one abrasive and the other having absorbent or degreasing properties. The layers made of a material based on microfibers are in particular advantageous for their absorbent and degreasing and / or wiping properties. This type of structure is particularly effective in complementing the anti-grease performance of a detergent liquid and helps remove certain soils from tableware, such as traces of lipstick on glasses. The outer layers also improve the retention of liquid inside the sponge, further limiting product loss during use while increasing foam production on all free sides of the sponge. .
Typiquement, les éponges mono ou multicouches de l'invention présentent une résistance à la compression à 40% mesurée selon la norme ISO3386 comprise entre 1 et 7 kPa et de préférence entre 3 et 5 kPa.Typically, the mono or multilayer sponges of the invention have a compressive strength at 40% measured according to the ISO3386 standard of between 1 and 7 kPa and preferably between 3 and 5 kPa.
Egalement, l'éponge offre une capacité de rétention supérieure à 20g/100cm3, de préférence supérieure à 30g/100cm3 tel que mesurée après saturation de l'éponge après des pressions sous l'eau puis égouttage sur un plan incliné à 45° pendant une minute par différence rapportée au volume de l'éponge du poids de l'éponge une fois égouttée avec le poids initial sec. Les éponges selon la présente invention restent donc particulièrement utiles malgré la présence des orifices.Also, the sponge offers a retention capacity greater than 20g / 100cm 3 , preferably greater than 30g / 100cm 3 as measured after saturation of the sponge after pressure under water and then draining on a plane inclined at 45 ° for one minute as the difference between the volume of the sponge and the weight of the sponge when drained with the initial dry weight. The sponges according to the present invention therefore remain particularly useful despite the presence of the orifices.
Grâce aux éponges de l'invention, l'utilisateur a désormais la possibilité de recharger l'éponge avec une quantité suffisante de liquide nettoyant pour nettoyer la vaisselle sans aucun gaspillage ni surconsommation. L'utilisation de l'éponge pour nettoyer plusieurs surfaces ou articles de vaisselle entre deux rechargements permet d'éviter de saturer l'éponge en permanence et offre une réelle économie de liquide vaisselle.Thanks to the sponges of the invention, the user now has the possibility of recharging the sponge with a sufficient quantity of cleaning liquid to clean the dishes without any waste or overconsumption. Using the sponge to clean several surfaces or dishwashing items between two refills avoids permanently saturating the sponge and offers real savings in dishwashing liquid.
En outre, l'éponge selon l'invention génère une mousse importante, répartie sur toutes les surfaces disponibles de l'éponge, et non de façon localisée ce qui permet à l'utilisateur de vérifier visuellement qu'il subsiste du liquide détergent capable de nettoyer la surface ou les articles à laver. Ainsi, il n'est pas incité à recharger régulièrement l'éponge ou à rajouter du liquide dans le milieu de lavage.In addition, the sponge according to the invention generates a significant foam, distributed over all the available surfaces of the sponge, and not in a localized manner, which allows the user to visually verify that there is still detergent liquid capable of clean the surface or items to be washed. Thus, there is no incentive to regularly reload the sponge or to add liquid to the washing medium.
L'utilisateur dispose désormais d'un repère visuel qui lui permet de recharger l'éponge avec une quantité constante de liquide vaisselle. Il lui est également possible d'introduire l'embout du flacon de liquide nettoyant directement dans l'un des orifices et de le remplir à l'aide d'une simple pression sur le flacon.The user now has a visual cue that allows him to refill the sponge with a constant amount of dishwashing liquid. It is also possible for him to introduce the tip of the bottle of cleaning liquid directly into one of the openings and to fill it using a simple pressure on the bottle.
Ces avantages sont particulièrement utiles lorsque la vaisselle est faite sous l'eau courante et permet de réduire la consommation de liquide nettoyant et par la même occasion d'optimiser les propriétés du produit utilisé par rapport à l'utilisation des éponges de l'art antérieur.These advantages are particularly useful when the dishes are done under running water and make it possible to reduce the consumption of cleaning liquid and at the same time to optimize the properties of the product used compared to the use of the sponges of the prior art. .

De plus, la cavité 22 comporte un fond 24 dispose à l'intérieur de l'éponge 20. Le fond 24 de la cavité 22 peut notamment être situe au centre de l'éponge 20. La cavité 22 débouche par ailleurs sur une surface libre 26 de l'éponge 20 en formant un orifice 28. Le terme contour utilise ici correspond également au bord ou au rebord de l'orifice 28 sur la surface libre 26 de l'éponge 20. Le contour correspond à l'arête formée sur la surface libre 26 de l'éponge 20 par l'orifice 28.In addition, the
Le contour de l'orifice 28 sur la surface libre 26 est tel que la distance maximale entre deux points du contour de l'orifice 28 est comprise entre 3, de préférence 5, de préférence encore 8, et 20 mm, de préférence 15 mm. En d'autres termes, sur l'ensemble des points du contour, la distance maximale entre deux points de ce contour est comprise entre 3 et 20 mm.The contour of the
Un utilisateur de l'éponge 20 peut ainsi introduire du produit vaisselle directement à l'intérieur de l'éponge 20 via l'orifice 28. Le produit vaisselle traverse l'éponge 20 via la cavité 22 jusqu'au fond 24 de la cavité 22. La cavité 22 a alors une fonction de guide du liquide vaisselle vers l'intérieur de l'éponge. Une grande partie du produit vaisselle versé dans la cavité 22 est alors emmagasinée dans les pores de l'éponge 20 situes à proximité du fond 24 de la cavité 22. Ces pores, situés au cœur de l'éponge 20, diffusent le liquide vaisselle de manière plus progressive que les pores situes à proximité de la surface de l'éponge 20 (qui ont tendance à se vider au contact de l'eau. Par suite, l'éponge 20 produit de la mousse durant un temps plus long qu'une éponge imbibée de produit vaisselle uniquement en surface. Par suite, l'utilisateur n'est pas incité à recharger l'éponge 20 en liquide vaisselle aussi régulièrement qu'il ne l'est avec une éponge classique. L'efficacité perçue par l'utilisateur du produit vaisselle et de l'éponge 20 est ainsi améliorée.A user of the

Le test décrit ci-dessous permet de comparer le pouvoir moussant d'éponges qui sont imprégnées avec une même quantité d'un même détergent.The test described below makes it possible to compare the foaming power of sponges which are impregnated with the same quantity of the same detergent.
Le test est réalisé à l'aide d'un dispositif de compression constitué de deux parois parallèles entre lesquelles est placée l'éponge à tester et dont une paroi est mobile de manière à comprimer l'éponge dans le sens de l'épaisseur à un taux de compression fixé à 50% de l'épaisseur initiale. Une des deux parois est percée de trous permettant d'évacuer le liquide en mode de compression. La
Au début du test, l'éponge est en positionnée debout sur un fond horizontal (évier par exemple) muni d'une évacuation d'eau, et une de ses faces principales reste accolée à la paroi fixe de la presse durant l'essai. Les faces latérales de l'éponge sont libres.At the start of the test, the sponge is positioned upright on a horizontal bottom (sink for example) provided with a water outlet, and one of its main faces remains attached to the fixed wall of the press during the test. The side faces of the sponge are free.
L'éponge à tester est tout d'abord imprégnée avec un détergent de référence. Une quantité de référence de 50g d'une solution de détergent dilué à 1/25 (soit incorporation de 2g de détergent concentré). Dans un premier temps, il est nécessaire de faire pénétrer la solution de façon homogène dans l'éponge en appliquant quelques pressions manuelles modérées (en évitant les débordements éventuels de liquide). Puis, la formation de mousse est mesurée en comprimant l'éponge sous un courant continu d'eau adoucie avec un débit égal à 2 l/min positionné au-dessus du centre de la face supérieure de l'éponge.The sponge to be tested is first of all impregnated with a reference detergent. A reference quantity of 50g of a detergent solution diluted to 1/25 (ie incorporation of 2g of concentrated detergent). First, it is necessary to make the solution penetrate homogeneously into the sponge by applying a few moderate manual pressures (avoiding any liquid overflows). Then, the foaming is measured by compressing the sponge under a continuous stream of softened water with a flow rate equal to 2 l / min positioned above the center of the upper face of the sponge.
Dans le présent exemple, un détergent dont le pouvoir moussant, mesuré conformément à la norme ISO 696:1975 mesurée à 20 °C au lieu de 50°C, est de 160 ml après 30 secondes, 154 ml après 3 minutes et 152 ml après 5 minutes, est utilisé pour tester des éponges mesurant 160x130x40mm. Le test est alors réalisé selon le protocole suivant:
- on place l'éponge en position verticale dans le pressoir.
- on fait couler le courant d'eau (qui sera maintenu continuellement sur l'éponge durant le test) et immédiatement après:
- 1) On comprime l'éponge puis la relâche pendant environ 3s
- 2) On attend environ 12s
- on répète le cycle 1) & 2) encore 9 fois, toutes les 15s.
- au terme de la 15ème seconde du dixième cycle, on retire l'éponge puis extrait la solution qu'elle contient par pressage manuel à fond, afin de la récolter dans une éprouvette graduée (par l'intermédiaire d'un entonnoir).
- 30s après la fin du dernier cycle, on mesure le volume de mousse qui émerge au-dessus de l'eau dans l'éprouvette.
- the sponge is placed in a vertical position in the press.
- we run the current of water (which will be kept continuously on the sponge during the test) and immediately after:
- 1) We compress the sponge then release it for about 3s
- 2) We wait about 12s
- cycle 1) & 2) is repeated 9 more times, every 15s.
- at the end of the 15th second of the tenth cycle, the sponge is removed and then the solution which it contains is extracted by fully manual pressing, in order to collect it in a graduated cylinder (via a funnel).
- 30s after the end of the last cycle, the volume of foam which emerges above the water in the test tube is measured.

- t = 2m30s: Removal of the sponge and full manual pressure above a graduated cylinder.
- T = 3m00s: Measurement of the volume of foam produced.
La mesure représente le rapport entre le volume de mousse généré après dix compressions et le volume de l'éponge, en pourcentage.The measurement represents the ratio between the volume of foam generated after ten compressions and the volume of the sponge, in percentage.
