Description

Domaine techniqueTechnical area

La présente invention concerne une éponge grattante non rayante, comprenant un récurant constitué de grains.The present invention relates to a non-scratching scratching sponge, comprising a scouring agent consisting of grains.

Art antérieurPrior art

De manière classique, une éponge grattante est constituée d'une base en matière spongieuse et d'une couche récurante en fibres. Cette solution n'est pas entièrement satisfaisante. En premier lieu, la couche récurante en fibres couvre les alvéoles de la base, diminuant la capacité absorbante de l'éponge. De plus, les fibres piègent les saletés qui sont ensuite difficiles à éliminer.Conventionally, a scraping sponge consists of a base of spongy material and a scouring layer of fibers. This solution is not entirely satisfactory. First, the scouring layer of fibers covers the cells of the base, reducing the absorbent capacity of the sponge. In addition, the fibers trap dirt which is then difficult to remove.

Il est connu également le document WO 2011/056632 qui décrit une éponge selon le préambule de la revendication 1. Cependant, la capacité absorbante de cette éponge peut être améliorée.It is also known the document WO 2011/056632 which describes a sponge according to the preamble of claim 1. However, the absorbent capacity of this sponge can be improved.

Exposé de l'inventionDisclosure of the invention

Le but de la présente invention est de proposer une éponge grattante améliorée.
A cet effet, l'invention a pour objet une éponge grattante, comprenant une base en matière spongieuse et un récurant déposé sur la base, caractérisée en ce que le récurant est constitué de grains de matière ayant une dureté supérieure à la matière spongieuse et inférieure à 4,5 sur l'échelle de Mohs. Ainsi, l'éponge selon l'invention est non rayante et plus hygiénique que les éponges grattantes munies de fibres, tout en étant peu coûteuse et efficace.The object of the present invention is to provide an improved scraping sponge.
To this end, the invention relates to a scraping sponge, comprising a base made of spongy material and a scouring agent deposited on the base, characterized in that the scouring agent consists of grains of material having a hardness greater than the spongy material and less at 4.5 on the Mohs scale. Thus, the sponge according to the invention is non-scratching and more hygienic than the scraping sponges provided with fibers, while being inexpensive and efficient.

La base a une surface comportant des alvéoles ouvertes munie de rebords et les grains récurants sont déposés sur les rebords des alvéoles. Ainsi, les alvéoles ne sont pas comblées par le récurant, à la différence des éponges existant actuellement sur le marché, munies de fibres.
Selon d'autres caractéristiques avantageuses de l'invention, prises isolément ou en combinaison :

  • La base est constituée de matière végétale.
  • Le récurant recouvre moins de 50 % de l'aire définie par les alvéoles sur la surface, de préférence moins de 20 %.
  • Le récurant est constitué de matière végétale.
  • Le récurant est réalisé à base de noyau(x) ou coque(s) de fruit(s).
  • Le noyau ou la coque est concassé(e).
  • Le noyau de fruit est du type abricot ou pêche.
  • La coque de fruit est du type noix ou noisette.
  • Le récurant a une granulométrie comprise entre 100 à 750 µm.
  • Le récurant est comprend une densité surfacique comprise entre 200 et 500 g/m2.
  • Le récurant est fixé sur la base par un moyen adhésif.
  • Le récurant est fixé sur la base directement par le moyen adhésif, sans support intermédiaire (par exemple un support laminé sur la base). Autrement dit, le récurant est collé directement sur la base.
  • Le moyen adhésif est déposé sur les rebords des alvéoles à la surface de la base.
  • Le moyen adhésif recouvre moins de 50 % de l'aire définie par les alvéoles sur la surface, de préférence moins de 20 %.
  • Le moyen adhésif est résistant au détergent.
The base has a surface comprising open cells provided with rims and the scouring grains are deposited on the rims of the cells. Thus, the cells are not filled by the scouring agent, unlike the sponges currently on the market, provided with fibers.
According to other advantageous characteristics of the invention, taken individually or in combination:
  • The base is made of plant material.
  • The scouring agent covers less than 50% of the area defined by the cells on the surface, preferably less than 20%.
  • The scouring agent is made from plant material.
  • The scouring agent is made from fruit kernel (s) or shell (s).
  • The core or shell is crushed.
  • The fruit stone is apricot or peach type.
  • The fruit shell is of the nut or hazelnut type.
  • The scouring agent has a particle size of between 100 to 750 µm.
  • The scouring agent has a surface density of between 200 and 500 g / m2.
  • The scouring agent is attached to the base by adhesive means.
  • The scouring agent is attached to the base directly by the adhesive means, without any intermediate support (eg a laminate support on the base). In other words, the scouring agent is glued directly to the base.
  • The adhesive medium is deposited on the edges of the cells on the surface of the base.
  • The adhesive means covers less than 50% of the area defined by the cells on the surface, preferably less than 20%.
  • The adhesive medium is detergent resistant.

[Fig. 1] est une vue en perspective d'une éponge conforme à l'invention.The invention will be better understood on reading the description which follows, given solely by way of non-limiting example and made with reference to the appended drawing:
[ Fig. 1 ] is a perspective view of a sponge according to the invention.

Description détaillée de l'inventionDetailed description of the invention

La figure 1 montre une éponge (1) conforme à l'invention, du type grattante / récurrante.The figure 1 shows a sponge (1) according to the invention, of the scratching / recurring type.

L'éponge (1) comprend une base (10), un récurant non rayant (20), et un moyen adhésif (30) interposé entre la base (10) et le récurant (20), de manière à coller le récurant (20) directement sur la base (10).The sponge (1) comprises a base (10), a non-scratching scouring (20), and an adhesive means (30) interposed between the base (10) and the scouring (20), so as to stick the scouring (20) ) directly on the base (10).

La base (10) comprend une surface inférieure (11) et une surface supérieure (12) sensiblement planes. La base (10) comprend une surface latérale (13) de profil courbé, reliant les surfaces (11, 12). La base (10) est réalisée en matière végétale spongieuse.The base (10) includes a substantially planar lower surface (11) and upper surface (12). The base (10) comprises a side surface (13) of curved profile, connecting the surfaces (11, 12). The base (10) is made of spongy plant material.

La base (10) est munie d'alvéoles disposées à cœur et en surface, communiquant les unes avec les autres. La surface (12) comporte des alvéoles (14) ouvertes munie de rebords. Le récurant (20) est fixé sur les rebords des alvéoles (14) de la surface (12) grâce au moyen adhésif (30).The base (10) is provided with cells arranged at the heart and on the surface, communicating with each other. The surface (12) has open cells (14) provided with rims. The scouring agent (20) is fixed to the edges of the cells (14) of the surface (12) by means of the adhesive means (30).

Le récurant (20) est constitué de matière granulaire plus dure que la matière spongieuse de la base (10). De préférence, le récurant (20) est constitué de matière végétale, plus écologique. Le récurant (20) peut être réalisé à base de noyau de fruit concassé, du type abricot ou pêche par exemple. Entre autre alternative, le récurant (20) peut être réalisé à base de coque de fruit concassée, du type noix ou noisette par exemple. Le récurant (20) peut être réalisé à partir de noyaux et/ou coque(s) de différents fruits. Selon une autre alternative, le récurant (20) peut être constitué de matière synthétique. Le récurant (20) a généralement une granulométrie comprise entre 100 à 750 µm.The scouring agent (20) is made of granular material harder than the spongy material of the base (10). Preferably, the scouring agent (20) consists of plant material, which is more ecological. The scouring agent (20) can be made from crushed fruit kernels, of the apricot or peach type for example. Among other alternatives, the scouring agent (20) can be made from crushed fruit shells, of the walnut or hazelnut type for example. The scouring agent (20) can be made from stones and / or shell (s) of different fruits. According to another alternative, the scouring agent (20) can be made of synthetic material. The scouring agent (20) generally has a particle size of between 100 to 750 µm.

Selon une caractéristique essentielle de l'invention, le récurant (20) a une dureté inférieure à 4,5 sur l'échelle de Mohs. Ainsi, le récurant (20) est moins dur que le verre, ayant une dureté comprise entre 4,5 et 6,5 sur l'échelle de Mohs. Cela confère son caractère non rayant à l'éponge (1).According to an essential characteristic of the invention, the scouring agent (20) has a hardness of less than 4.5 on the Mohs scale. Thus, the scouring agent (20) is less hard than glass, having a hardness between 4.5 and 6.5 on the Mohs scale. This gives the sponge its non-scratching character (1).

De préférence, le récurant (20) est déposé sur la base (10) avec une densité surfacique comprise entre 200 et 500 g/m2.Preferably, the scouring agent (20) is deposited on the base (10) with a surface density of between 200 and 500 g / m2.

Le moyen adhésif (30) est déposé sur la surface supérieure (12) de la base (10), sur les rebords des alvéoles (14), puis les grains de récurant (20) sont déposés sur le moyen adhésif (30), toujours sur les rebords des alvéoles (14). Ainsi, les alvéoles (14) ne sont pas comblées par les grains de récurant (20) collés sur la surface (12), et l'éponge (1) conserve sa capacité absorbante. Des ouvertures (22) sont formées à travers la couche de récurant (20), en regard des alvéoles (14).The adhesive means (30) is deposited on the upper surface (12) of the base (10), on the edges of the cells (14), then the grains of scouring (20) are deposited on the adhesive means (30), still on the edges of the cells (14). Thus, the cells (14) are not filled by the grains of scouring (20) stuck on the surface (12), and the sponge (1) retains its absorbent capacity. Openings (22) are formed through the layer of scouring agent (20), facing the cells (14).

Avantageusement, le moyen adhésif (30) et le récurant (20) sont déposés sur la base (10) de manière à recouvrir moins de 50 % de l'aire définie par les alvéoles (14) sur la surface (12), de préférence moins de 20 %.Advantageously, the adhesive means (30) and the scouring agent (20) are deposited on the base (10) so as to cover less than 50% of the area defined by the cells (14) on the surface (12), preferably less than 20%.

Le moyen adhésif (30) peut être de tout type adapté à l'application visée. De préférence, le moyen adhésif (30) est en matière naturelle souple, résistante au détergent.The adhesive means (30) can be of any type suitable for the intended application. Preferably, the adhesive means (30) is made of flexible natural material resistant to detergent.

Par ailleurs, l'éponge (1) peut être conformée différemment sans sortir du cadre de l'invention, qui est défini par les revendications. En outre, les caractéristiques techniques des différents modes de réalisation et variantes mentionnés ci-dessus peuvent être, en totalité ou pour certaines d'entre elles, combinées entre elles. Ainsi, l'éponge (1) peut être adaptée en termes de coût, de fonctionnalités et de performance.Furthermore, the sponge (1) can be shaped differently without departing from the scope of the invention, which is defined by the claims. In addition, the technical characteristics of the various embodiments and variants mentioned above can be, in whole or for some of them, combined with one another. Thus, the sponge (1) can be adapted in terms of cost, functionality and performance.
