Prior to evacuation the porous material can be impregnated with the active substance, an odour-releasing agent e.g. bone oil by dipping or spraying. The porous material is pref. ligneous in origin, e.g. wood or bark, and can be spread around flowers or shrubs to keep animals away. In variants the active substance can be a pesticide or a slow-release fertiliser. ADVANTAGE - Protects plants from damage by animals and suppresses weed growth at same time.

Description

La présente invention concerne un procédé d'imprégnation d'un support poreux par des composés olfactifs d'une matière active. The present invention relates to a method of impregnating a porous support with olfactory compounds of an active material.

L'invention concerne également des pièces de bois telles que déchets ligneux, poteaux, planches imprégnées d'une matière olfactive, et notamment des morceaux d'écorces d'arbre imprégnés d'un agent répulsif à l'égard des animaux, et leur utilisation. The invention also relates to pieces of wood such as woody waste, posts, boards impregnated with an olfactory material, and in particular pieces of tree bark impregnated with a repellant for animals, and their use .

Les déchets ligneux sous forme de plaquettes, en particulier sous forme de morceaux d'écorces d'arbres, sont destinés entre autre à être répandus sur le sol pour protéger les cultures notamment les arbustes et fleurs. Woody waste in the form of chips, in particular in the form of pieces of tree bark, is intended, among other things, to be spread on the ground to protect crops, in particular shrubs and flowers.

Ils permettent ainsi une bonne respiration de la terre, de maintenir la terre humide et d'empêcher les mauvaises herbes de pousser.They allow the soil to breathe well, keep the soil moist and prevent weeds from growing.

Cependant, les déchets ligneux ainsi disposés en couche sur la terre présentent l'inconvénient de pouvoir être très facilement éparpillés par des animaux, notamment par les animaux domestiques tels que les chiens et les chats. Outre le fait que l'action des déchets ligneux est ainsi annihilée, il faut de plus procéder à un ramassage fastidieux des déchets ligneux éparpillés. However, the woody waste thus arranged in a layer on the ground has the drawback of being able to be very easily scattered by animals, in particular by domestic animals such as dogs and cats. In addition to the fact that the action of woody waste is thus annihilated, it is also necessary to carry out a tedious collection of the scattered woody waste.

Les piquets, planches, poteaux sont également couramment utilisés pour empêcher les animaux d'accéder à certains lieux. Stakes, boards, poles are also commonly used to prevent animals from accessing certain places.

D'autre part, on connaît des produits qui permettent de tenir éloignés les animaux d'un endroit. De tels produits se présentent généralement sous forme de granules imprégnés d'un agent répulsif. Ainsi la demande de brevet FR-9108443 décrit des granules imprégnés d'un agent répulsif olfactif tel que de l'huile d'os. On the other hand, there are known products which make it possible to keep animals away from a place. Such products are generally in the form of granules impregnated with a repellant. Thus patent application FR-9108443 describes granules impregnated with an olfactory repellant such as bone oil.

La présente invention consiste à imprégner un support poreux d'une matière active olfactive, et notamment des pièces de bois. The present invention consists in impregnating a porous support with an olfactory active material, and in particular pieces of wood.

On utilise ainsi le fort pouvoir d'absorption du bois: l'action olfactive exercée par les pièces de bois dure ainsi très longtemps, les composés olfactifs étant absorbés dans les porosités du bois. We thus use the strong absorption power of wood: the olfactory action exerted by the pieces of wood thus lasts a very long time, the olfactory compounds being absorbed in the porosities of the wood.

La présente invention propose également un procédé d'imprégnation qui permet de prolonger de manière importante l'action olfactive des pièces de bois. The present invention also provides an impregnation process which makes it possible to significantly extend the olfactory action of the pieces of wood.

Le procédé d'imprégnation selon l'invention consiste à imprégner un support poreux de composés olfactifs d'une matière active, notamment un support ligneux. The impregnation method according to the invention consists in impregnating a porous support with olfactory compounds of an active material, in particular a woody support.

Il comprend successivement les étapes suivantes:
a) on fait le vide dans une enceinte fermée contenant le support poreux;
b) on introduit la matière active préalablement chauffée dans ladite enceinte maintenue sous vide;
c) on augmente la pression dans l'enceinte à une pression supérieure à la pression atmosphérique;
d) on maintient ladite pression supérieure à la pression atmosphérique dans l'enceinte; et
e) on évacue la matière active résiduelle et on rétablit la pression atmosphérique dans l'enceinte.It successively includes the following stages:
a) a vacuum is created in a closed enclosure containing the porous support;
b) the active material previously heated is introduced into said enclosure maintained under vacuum;
c) the pressure in the enclosure is increased to a pressure higher than atmospheric pressure;
d) said pressure is maintained above atmospheric pressure in the enclosure; and
e) the residual active material is removed and the atmospheric pressure is restored in the enclosure.

Le procédé selon l'invention permet, grâce à la mise sous vide, d'augmenter le pouvoir absorbant du support poreux. The method according to the invention makes it possible, by virtue of the vacuum, to increase the absorbency of the porous support.

Puis, grâce à la mise sous pression de l'enceinte, les composés olfactifs sont très bien absorbés par le support poreux. Then, thanks to the pressurization of the enclosure, the olfactory compounds are very well absorbed by the porous support.

Selon un autre aspect de l'invention, des pièces de bois, notamment des morceaux d'écorces d'arbres destinés à être répandus sur le sol pour protéger les cultures, en particulier les arbustes et les arbres, sont imprégnées, grâce au procédé de l'invention, d'une matière active constitue d'un agent reulsif olfactif à l'égard des animaux. According to another aspect of the invention, pieces of wood, in particular pieces of tree bark intended to be spread on the ground to protect crops, in particular shrubs and trees, are impregnated, thanks to the process of the invention, an active ingredient constitutes a reulsive olfactory agent with respect to animals.

Les pièces de bois ainsi obtenues ont une action répulsive à l'égard des an naux tendant une durée accrue par rapport à des pièces de bois imprégnées d'un agent répulsif par simple trempage ou pulvérisation. The pieces of wood thus obtained have a repulsive action with regard to the annals tending to an increased duration compared to pieces of wood impregnated with a repellant by simple soaking or spraying.

Selon une version avantageuse de l'invention, l'agent répulsif est de préférence de l'huile d'os. According to an advantageous version of the invention, the repellant is preferably bone oil.

La durée de l'action répulsive est alors prolongée car l'huile d'os, comme toute matière huileuse, ne se dilue pas dans l'eau. L'eau de pluie ou d'arrosage pénètre peu dans le bois et n'entraîne pas avec elle l'huile d'os. The duration of the repulsive action is then extended because bone oil, like all oily matter, does not dilute in water. Rainwater or sprinkler water penetrates little into the wood and does not carry bone oil with it.

Selon une version préférée de l'invention, les pièces de bois peuvent également contenir un pesticide, tel qu'un insecticide qui protège les plantes des insectes nuisibles, ou un engrais qui diffuse dans la terre des éléments nécessaires à la croissance des plantes. According to a preferred version of the invention, the pieces of wood may also contain a pesticide, such as an insecticide which protects plants from harmful insects, or a fertilizer which diffuses into the soil elements necessary for plant growth.

Lorsque les pièces de bois sont des déchets ligneux, elles sont disposées en couches sur la terre, autour des plantations. When the pieces of wood are woody waste, they are arranged in layers on the ground, around the plantations.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ciaprès. Other features and advantages of the invention will become apparent in the description below.

Au dessin annexé:
- la figure 1 est une courbe représentant l'évolution de la pression dans le procédé selon l'invention;
- la figure 2 est un exemple d'utilisation des déchets ligneux selon l'invention.In the attached drawing:
- Figure 1 is a curve showing the evolution of the pressure in the process according to the invention;
- Figure 2 is an example of the use of woody waste according to the invention.

On va décrire tout d'abord en référence à la figure 1, le procédé d'imprégnation d'un support poreux quelconque conforme à l'invention. We will first describe with reference to Figure 1, the method of impregnating any porous support according to the invention.

Le traitement proprement dit est réalisé à l'intérieur d'une enceinte adaptée au vide, à la pression et susnectible de recevoir à sa partie inférieure de ia matière active. Le support poreux à traiter est placé dans des paniers permettant de l'introduire et de le sortir ne enceinte aisément. L'enceinte comporte à sa partie inférieure un réservoir dans lequel la matière active est stockée et chauffée au préalable. The actual treatment is carried out inside an enclosure suitable for vacuum, pressure and capable of receiving active material at its lower part. The porous support to be treated is placed in baskets allowing it to be easily inserted and removed from the enclosure. The enclosure has at its lower part a reservoir in which the active material is stored and heated beforehand.

Dans l'étape a) du procédé, on fait le vide Pv dans l'enceinte fermée contenant le support poreux. La durée de cette étape dépend de la nature du support à traiter, de la pression résiduelle Pv à atteindre et des performances de la pompe à vide. Elle peut être comprise entre 5 et 75 minutes pour des pressions résiduelles Pv comprises entre 35 et 300 millibars. In step a) of the process, vacuum Pv is made in the closed enclosure containing the porous support. The duration of this step depends on the nature of the support to be treated, the residual pressure Pv to reach and the performance of the vacuum pump. It can be between 5 and 75 minutes for residual pressures Pv between 35 and 300 millibars.

Puis on introduit la matière active préalablement chauffée dans l'enceinte maintenue sous vide. Pour ce faire, on ouvre généralement une paroi qui sépare le réservoir contenant la matière active du reste de l'enceinte. L'enceinte est alors immédiatement saturée en vapeurs de matière active. Selon la nature des supports et des composés olfactifs utilisés, cette étape b) dure de quelques minutes à plusieurs heures. La température de la matière active est généralement comprise entre 35"C et 1750C selon la composition. Then the active material previously heated is introduced into the enclosure maintained under vacuum. To do this, a wall is generally opened which separates the reservoir containing the active material from the rest of the enclosure. The enclosure is then immediately saturated with vapors of active material. Depending on the nature of the supports and the olfactory compounds used, this step b) lasts from a few minutes to several hours. The temperature of the active ingredient is generally between 35 "C and 1750C depending on the composition.

Puis, au cours de l'étape c), on "casse" le vide pour amener en quelques minutes l'enceinte à une pression Ps supérieure à la pression atmosphérique. Then, during step c), the vacuum is "broken" to bring the enclosure in a few minutes to a pressure Ps greater than atmospheric pressure.

On maintient ensuite la pression Ps supérieure à la pression atmosphérique dans l'enceinte. Cette étape d) a une durée qui varie de 5 à 90 minutes selon la nature du support à imprégner et la composition de la matière active. Les valeurs de pression Ps sont comprises entre 0,5 et 9 bars. The pressure Ps is then maintained greater than atmospheric pressure in the enclosure. This step d) has a duration which varies from 5 to 90 minutes depending on the nature of the support to be impregnated and the composition of the active material. The pressure values Ps are between 0.5 and 9 bars.

Puis, au début de l'étape suivante e), on évacue hors de l'enceinte la matière active résiduelle. Then, at the start of the next step e), the residual active material is removed from the enclosure.

Ensuite on "casse" la pression pour ramener le contenu de l'enceinte à la pression atmosphérique. Cette phase dure quelques ninutes. Le cycle est alors terrine. Then we "break" the pressure to bring the contents of the enclosure to atmospheric pressure. This phase lasts a few ninutes. The cycle is then terrine.

Selon les supports utilisés , celui-ci peut, avant l'étape a) du procédé, être imprégné préalablement c nature active par trempage ou w sation.  Depending on the supports used, this can, before step a) of the process, be impregnated beforehand with an active nature by soaking or wation.

Des pièces de bois, telles que des déchets ligneux, des poteaux, des planches peuvent être imprégnées d'une matière active olfactive par le procédé selon l'invention décrit ci-dessus. Pieces of wood, such as woody waste, posts, boards can be impregnated with an olfactory active material by the process according to the invention described above.

Dans certains cas, la matière active est une composition parfumante. In certain cases, the active material is a perfuming composition.

Les supports poreux, tels que des écorces d'arbres, peuvent ainsi être placés dans une pièce d'une maison associant ainsi à leur fonction décorative une action désodorisante.  Porous supports, such as tree bark, can thus be placed in a room in a house, thus associating their deodorizing action with their decorative function.

Lorsque les pièces de bois, notamment des morceaux d'écorces d'arbres sont destinées à être répandues sur le sol pour protéger les cultures, la matière active peut etre un agent répulsif olfactif à l'égard des animaux. When the pieces of wood, in particular pieces of tree bark are intended to be spread on the ground to protect crops, the active ingredient can be an olfactory repellant against animals.

L'agent répulsif est de préférence de l'huile d'os. Cette dernière est introduite en quantité telle que les dechets ligneux contiennent finalement, environ 1 à 10% en poids d'huile d'os. The repellant is preferably bone oil. The latter is introduced in an amount such that the wood waste finally contains, approximately 1 to 10% by weight of bone oil.

Une telle quantité d'huile est suffisante pour tenir éloignés par l'odeur les animaux domestiques. Such an amount of oil is sufficient to keep pets away by smell.

Conformément à la figure 2, au moins une couche de déchets ligneux 1 imprégnés selon l'invention sont disposés sur la terre 2 autour des plantations 3. In accordance with FIG. 2, at least one layer of woody waste 1 impregnated according to the invention is disposed on the ground 2 around the plantations 3.

Les déchets ligneux 1 permettent à la fois une bonne respiration de la terre, de garder la terre humide, d'empêcher la pousse des mauvaises herbes et de tenir éloignés les animaux domestiques. Woody waste 1 allows the soil to breathe well, to keep the soil moist, to prevent weed growth and to keep pets away.

Comme illustré sur la figure 2, plusieurs couches de déchets ligneux 1 peuvent être superposées afin d'assurer une meilleure isolation du sol. As illustrated in FIG. 2, several layers of woody waste 1 can be superimposed in order to ensure better insulation of the soil.

Bien que toutes les couches puissent être constituées de déchets ligneux 1 i.,prégnes d'un agent répulsif, seule la couche supérieure, par souci d'économie, peut être constituée de déchets ligneux 1 imprégnés, sans que l'efficacité contre les animaux ne soit affectée. Although all the layers may consist of wood waste 1 i., Containing a repellant, only the upper layer, for reasons of economy, may consist of wood waste 1 impregnated, without effectiveness against animals is affected.

La matière active peut en outre comprendre un pesticide à effet de vapeur ou un engrais à libération progressive. The active ingredient may further include a vaporizing pesticide or a progressive release fertilizer.

Bien entendu, l'invention n'est pas limitée à l'exemple décrit ci-dessus et de nombreuses modifications peuvent être apportées sans sortir du cadre de l'invention. Of course, the invention is not limited to the example described above and many modifications can be made without departing from the scope of the invention.

Ainsi, d'autres déchets végétaux que les morceaux d'écorces d'arbres, ayant un bon pouvoir absorbant, peuvent être utilisés dans le cadre de l'invention. Thus, other plant waste than pieces of tree bark, having good absorbency, can be used in the context of the invention.

D'autres agents répulsifs olfactifs peuvent également être utilisés. Other olfactory repellents can also be used.

Des pièces de bois telles que piquet, pieu, planche, poteau... peuvent être imprégnées d'un agent répulsif olfactif. Pieces of wood such as a stake, stake, board, post ... can be impregnated with an olfactory repellant.

Les supports poreux peuvent être également constitués de copeaux de bois, de billes d'argile expansé, de films plastiques...  The porous supports can also consist of wood shavings, expanded clay balls, plastic films ...
