Description

LITIERE POUR ANIMAUX LITTER FOR ANIMALS
La présente invention concerne une litière pour animaux, notamment domestiques, tels que chats et chiens, ou de laboratoires.The present invention relates to a litter for animals, in particular domestic animals, such as cats and dogs, or for laboratories.
Il existe à ce jour de nombreuses formulations de litières proposées aux utilisateurs composées généralement d'une matière absorbante à laquelle différentes substances (virucides, odorantes...) sont ajoutées.To date, there are many formulations of litter offered to users generally composed of an absorbent material to which different substances (virucides, odors ...) are added.
Ces formulations ne sont toutefois pas exemptes de défauts ; ainsi, l'ajout d'une substance odorante ne fait que masquer l'odeur, parfois forte, des fèces et urines d'animaux. En outre, de telles formulations ne s'attachent pas suffisamment à préserver la sécurité des utilisateurs (notamment les propriétaires de ces animaux et leurs familles) et le respect de l'environnement à l'intérieur des locaux où sont récupérées ces fèces et urines ou à l'extérieur lorsqu'il s'agit de se débarrasser des litières usagées.These formulations are not, however, free from defects; thus, the addition of an odorous substance only masks the, sometimes strong, odor of animal faeces and urine. In addition, such formulations do not pay sufficient attention to preserving the safety of users (in particular the owners of these animals and their families) and respect for the environment inside the premises where these faeces and urine are collected or outside when it comes to getting rid of used litter.
La litière faisant l'objet de la présente invention ne comporte pas de tels défauts mais au contraire s'accompagne d'avantages liés à sa composition ; elle assure à la fois la sécurité des humains et des animaux et le respect de l'environnement.The litter which is the subject of the present invention does not have such defects but on the contrary is accompanied by advantages linked to its composition; it ensures both human and animal safety and respect for the environment.
S'agissant de la matière absorbante, la demanderesse a préféré ne pas utiliser de substances minérales : ces dernières sont difficilement éliminables et de plus polluent l'environnement des bacs où sont disposées les litières ; les chats ont par exemple l'habitude de recouvrir leurs déjections avec une partie de la litière, projetant ainsi une partie de cette dernière hors du bac où elle se trouve : il est alors pratiquement inévitable de marcher sur les granulés ainsi éjectés et de les écraser, créant ainsi une poussière collant aux chaussons ou chaussures des utilisateurs. Ces substances minérales, à base d'argile par exemple, ne sont que faiblement absorbantes, et les liquides forment souvent des boues avec les très fines particules provenant de ces substances.With regard to the absorbent material, the applicant preferred not to use mineral substances: the latter are difficult to remove and moreover pollute the environment of the tanks in which the litters are placed; cats, for example, are in the habit of covering their excrement with part of the litter, thus projecting part of the latter out of the bin where it is located: it is then practically inevitable to walk on the granules thus ejected and to crush them , thus creating a dust sticking to the slippers or shoes of the users. These mineral substances, based on clay for example, are only weakly absorbent, and the liquids often form sludges with the very fine particles coming from these substances.
Ainsi selon l'invention, la substance absorbante sera-t-elle composée d'un produit à base de bois (cellulose-lignine).Thus according to the invention, the absorbent substance will it be composed of a wood-based product (cellulose-lignin).
Préférentiellement ce produit aura été préalablement séché (3OO-5O0°C par exemple), tamisé et dépoussiéré.Preferably, this product will have been dried beforehand (3OO-5O0 ° C for example), sieved and dusted.
La demanderesse a trouvé que la meilleure granulométrie pour ce produit se situait entre 500 et 1100 μm environ.The Applicant has found that the best particle size for this product is between 500 and 1100 μm approximately.
Une telle granulométrie permet notamment un mélange intime avec les substances désinfectantes telles que le perborate de sodium dont la granulométrie sera de préférence choisie voisine de celle du composé absorbant. La proportion entre composé absorbant/substance désinfectante est prévue de façon à ce qu'un pH résiduel de l'ordre de 9 soit maintenu après l'hydrolyse des urines et des fèces par la substance désinfectante ; il a été noté que cette hydrolyse s'effectuait de façon régulière en raison notamment de l'homogénéité du mélange en terme de granulométrie. Avantageusement une amide aliphatique, tel que la Tetra Acétyl Ethylène Diamine (TAED), ayant un rôle aseptisant, sera ajoutée au mélange.Such a particle size allows in particular an intimate mixture with disinfectant substances such as sodium perborate, the particle size of which will preferably be chosen to be close to that of the absorbent compound. The proportion between absorbent compound / disinfectant substance is provided so that a residual pH of the order of 9 is maintained after the hydrolysis of urine and faeces by the disinfectant substance; it has been noted that this hydrolysis takes place regularly, in particular due to the homogeneity of the mixture in terms of particle size. Advantageously, an aliphatic amide, such as Tetra Acetyl Ethylene Diamine (TAED), having a sanitizing role, will be added to the mixture.
La composition faisant l'objet de la présente invention, en raison de ses caractéristiques qualitatives et quantitatives, permet de maintenir le pH basique précité, ce qui présente les avantages suivants : inactivation, de façon irréversible, de la flore micro-organique (il a été testé que cette inactivation persistait 18-24 mois après utilisation de la litière) effet bactériostatiqueThe composition which is the subject of the present invention, due to its qualitative and quantitative characteristics, makes it possible to maintain the abovementioned basic pH, which has the following advantages: irreversible inactivation of the micro-organic flora (it has tested that this inactivation persisted 18-24 months after using the litter) bacteriostatic effect
- neutralisation de l'anaérobiose systématique habituelle, préservant ainsi l'environnement de toute incidence nosocomiale.- neutralization of the usual systematic anaerobiosis, thus preserving the environment from any nosocomial incidence.
Un autre avantage de la composition faisant l'objet de la présente invention est qu'elle évite le phénomène de mottage particulièrement gênant dans le cas des litières traditionnelles.Another advantage of the composition which is the subject of the present invention is that it avoids the caking phenomenon which is particularly troublesome in the case of traditional litters.
En outre, il sera particulièrement important d'éviter des « fines » ou poussières au niveau notamment du composé absorbant : ces dernières peuvent présenter en effet de nombreux inconvénients ; en usage domestique les poussières favorisent la transmission de germes par voie d'aérosol (toxoplasmose par exemple) alors qu'en laboratoire, ces poussières colmatent rapidement les filtres des salles blanches où sont rassemblés les animaux. Ainsi la transmission « infectieuse » et/ou « infectante » de l'animal à l'homme sera particulièrement réduite (ce qui n'est pas le cas pour les litières traditionnelles). L'environnement sera également préservé, le mélange final étant facilement incinérable, bio-dégradable et compostable, ce qui représente en terme d'environnement un avantage décisif sur les litières existantes.In addition, it will be particularly important to avoid "fines" or dust, in particular in the absorbent compound: the latter can indeed have numerous drawbacks; in domestic use, dust promotes the transmission of germs by aerosol (toxoplasmosis for example) while in the laboratory, this dust quickly clogs the filters of clean rooms where animals are gathered. Thus "infectious" and / or "infectious" transmission from animals to humans will be particularly reduced (which is not the case for traditional litter). The environment will also be preserved, the final mixture being easily incinerable, bio-degradable and compostable, which represents in terms of environment a decisive advantage over existing litter.
La sécurité de la litière faisant l'objet de la présente invention tient notamment au pH basique comme cela a déjà été mentionné : jusqu'à la capacité d'absorption par le composé absorbant, l'oxydation par le perborate de sodium assure une efficacité bactéricide certaine, et au-delà de cette capacité d'absorption, la salinité résiduelle du pH 9 offrira une garantie bactériostatique.The safety of the litter which is the subject of the present invention is due in particular to the basic pH as has already been mentioned: up to the absorption capacity by the absorbent compound, the oxidation by sodium perborate ensures bactericidal efficiency certain, and beyond this absorption capacity, the residual salinity of pH 9 will offer a bacteriostatic guarantee.
A titre d'exemple non limitatif, la demanderesse a réalisé un mélange comprenant : - de l'ordre de 80% de sciure de bois de l'ordre de 17% de perborate de sodiumBy way of nonlimiting example, the applicant has produced a mixture comprising: - around 80% sawdust around 17% sodium perborate
Le complément est assuré par la TAED, ces divers pourcentages étant donnés en poids du mélange, et la granulométrie préférentielle ayant déjà été citée dans la présente description.The complement is provided by TAED, these various percentages being given by weight of the mixture, and the preferred particle size having already been mentioned in the present description.
A titre également préférentiel, la sciure de bois, préalablement traitée comme indiqué, proviendra d'épicéa. Also preferentially, the sawdust, previously treated as indicated, will come from spruce.
