After the container 2 has been filled with the viscous liquid product to be packaged and before the drawing-off cock 3 has been replaced, a gas which is inert with respect to the packaged product is injected into the container 2 in sufficient quantity and at sufficient pressure to considerably reduce the deformation of the container 2 during emptying thereof.

Description

"Procédé de conditionnement d'un produit liquide
visqueux, tel qu'une lessive liquide, dans un emballage mixte
comportant une outre souple imperméable, équipée d'un
robinet de soutirage et logée dans un caisson rigide"
La présente invention concerne un procédé de conditionnement d'un produit liquide visqueux, tel qu'une lessive liquide, dans un emballage mixte comportant une outre souple imperméable, équipée d'un robinet de soutirage et logée dans un caisson rigide.
"Process for packaging a liquid product
viscous, such as liquid detergent, in mixed packaging
comprising a flexible waterproof skin, equipped with a
filling tap and housed in a rigid box "
The present invention relates to a method of packaging a viscous liquid product, such as a liquid detergent, in a mixed packaging comprising a flexible waterproof addition, equipped with a draw-off valve and housed in a rigid box.

Ce type d'emballage mixte est couramment utilisé pour conditionner du vin car il permet des soutirages répétés sans risque que le vin n aigrisse puisqu'à chaque soutirage, I'outre se déforme au volume du liquide restant, de sorte qu'il ne se produit aucun appel d'air à son intérieur. This type of mixed packaging is commonly used to condition wine because it allows repeated racking without the risk of the wine getting sour since each racking deforms to the volume of the remaining liquid, so that it does not produces no air draft inside.

Pour conditionner du vin dans ce type d'emballage, on retire le robinet de l'outre, on en évacue l'air, on la remplit de vin et l'on remet en place le robinet de soutirage. To condition wine in this type of packaging, the tap is removed from the bottle, the air is evacuated, it is filled with wine and the filling tap is replaced.

De préférence, pour s'assurer de l'absence totale d'air dans l'outre remplie de vin, avant la remise en place du robinet, on complète le remplissage de l'outre avec de l'azote qui refoule, à l'extérieur, I'air résiduel. Preferably, to ensure the total absence of air in the wine-filled bottle, before replacing the tap, the filling of the bottle is completed with nitrogen which flows back, outside, residual air.

Naturellement, au fur et à mesure de son vidage, l'outre se collapse et se fripe en formant des plis mais, lorsque le liquide est très fluide comme le vin, ces plis ne gênent pas son écoulement et leur formation est donc sans conséquence. Naturally, as it is emptied, the bottle collapses and crumples, forming folds, but when the liquid is very fluid like wine, these folds do not hinder its flow and their formation is therefore of no consequence.

Par contre, les plis formés par le collapsage de l'outre au cours du soutirage de ce produit provoquent la retenue d'une quantité non négligeable du produit liquide conditionné lorsqu'il est un peu visqueux, comme cela est le cas lorsqu'il s'agit d'une lessive liquide. On the other hand, the folds formed by the collapsing of the skin during the drawing off of this product cause the retention of a non-negligible quantity of the liquid product packaged when it is a little viscous, as is the case when it s is a liquid detergent.

Le procédé selon l'invention vise à permettre le conditionnement de produits liquides visqueux dans ce type d'emballage sans qu il en résulte la retenue d'une quantité sensible du produit à l'intérieur de l'outre. A cet effet, dans le procédé qu'elle concerne et qui est du type précité, après le remplissage de l'outre avec le produit liquide visqueux et avant la remise en place du robinet de soutirage, on injecte dans l'outre un gaz inerte, tel que l'azote, par rapport au produit conditionné, en quantité et sous une pression suffisantes pour maintenir pour maintenir constamment au-dessus du niveau de liquide, jusqu'au vidage complet de l'outre, une zone non déformée des parois de l'outre. The method according to the invention aims to allow the packaging of viscous liquid products in this type of packaging without resulting in the retention of a significant amount of the product inside the bottle. To this end, in the process which it relates to and which is of the aforementioned type, after filling the bottle with viscous liquid product and before replacing the draw-off valve, an inert gas is injected into the bottle. , such as nitrogen, in relation to the packaged product, in sufficient quantity and under pressure to maintain, to maintain constantly above the level of liquid, until the emptying of the addition, an undistorted zone of the walls of otter.

La présence de ce gaz au-dessus du niveau du liquide visqueux crée, à l'intérieur de l'outre, une pression légère, suffisante pour réduire considérablement la déformation de l'outre et empêcher la formation de plis au cours de son vidage. Ainsi, malgré sa viscosité, le liquide peut s'écouler librement le long des parois de l'outre qui viennent d'être libérées de la présence du liquide visqueux et la quantité de ce produit subsistant à l'intérieur de l'outre, après son vidage total, est-absolument négligeable. The presence of this gas above the level of the viscous liquid creates, inside the bottle, a slight pressure, sufficient to considerably reduce the deformation of the bottle and prevent the formation of folds during its emptying. Thus, despite its viscosity, the liquid can flow freely along the walls of the skin which have just been freed from the presence of the viscous liquid and the quantity of this product remaining inside the skin, after its total emptying is absolutely negligible.

De toute façon, I'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, le procédé selon l'invention:
Figures I et 2 sont des vues similaires représentant un emballage mixte selon l'invention dans le cas de son utilisation, respectivement sans et avec mise en oeuvre du procédé de l'invention.
In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, the method according to the invention:
Figures I and 2 are similar views showing a mixed packaging according to the invention in the case of its use, respectively without and with implementation of the method of the invention.

Comme indiqué précédemment, le procédé de l'invention concerne le conditionnement d'un produit liquide visqueux dans un emballage mixte comportant une outre 2 en matière souple, imperméable au produit à conditionner, telle qu'en PVC ou polyéthylène, et équipée d'un robinet de soutirage 3 logé dans un caisson 4 rigide tel qu'en carton ou autre similaire. As indicated above, the method of the invention relates to the packaging of a viscous liquid product in a mixed packaging comprising a further 2 of flexible material, impermeable to the product to be packaged, such as PVC or polyethylene, and equipped with a withdrawal valve 3 housed in a rigid box 4 such as cardboard or the like.

Ce type de conditionnement mixte est couramment utilisé pour conditionner du vin que l'utilisateur peut prélever par soutirages successifs, sans risque que la quantité restant dans ce conditionnement mixte ne soit altérée. En effet, lors de chaque soutirage, l'outre 2 en matière souple se déforme de manière que son volume intérieur demeure constamment égal à celui du liquide existant, ce qui engendre son collapsage, c'est-à-dire la formation de plis entre ses parties de paroi qui ont tendance à s'appliquer l'une contre l'autre, comme illustré sur la figure 1. This type of mixed packaging is commonly used to package wine that the user can collect by successive racking, without risk that the quantity remaining in this mixed packaging will be altered. Indeed, during each racking, the addition 2 of flexible material deforms so that its internal volume remains constantly equal to that of the existing liquid, which generates its collapsing, that is to say the formation of folds between its wall parts which tend to press against each other, as illustrated in FIG. 1.

On conçoit aisément que l'utilisation de ce type de conditionnement avec un produit visqueux, c'est-à-dire dont l'écoulement est rendu difficile par sa nature, ne peut pas convenir de la manière habituelle en raison des pertes trop importantes de liquide correspondant au liquide résiduel subsistant dans l'emballage en fin de vidage. It is easily understood that the use of this type of packaging with a viscous product, that is to say the flow of which is made difficult by its nature, cannot be suitable in the usual way because of the excessive losses of liquid corresponding to the residual liquid remaining in the packaging at the end of emptying.

Le conditionnement d'un liquide de faible viscosité, tel que du vin, dans ce type d'emballage se fait habituellement de la manière suivante : on retire le robinet de soutirage 3 de l'outre 2, on en évacue l'air, on la remplit du liquide à conditionner et l'on remet en place le robinet de soutirage 3. The packaging of a liquid of low viscosity, such as wine, in this type of packaging is usually done in the following way: we withdraw the tap 3 from the bottle 2, we evacuate the air, we fills it with the liquid to be conditioned and the withdrawal tap 3 is replaced.

Selon le procédé de l'invention, pour éliminer tout risque de collapsage de l'outre 2 et empêcher le collapsage de sa paroi, au moins dans sa partie située juste au-dessus duu niveau de liquide restant jusqu'à son vidage complet ou presque, après le remplissage de l'outre 2 avec le produit liquide visqueux à conditionner, tel qu'une lessive liquide et avant la remise en place du robinet de soutirage 3, on injecte dans l'outre 2 un gaz inerte par rapport au produit conditionné. According to the method of the invention, in order to eliminate any risk of collapsing of the skin 2 and to prevent the collapsing of its wall, at least in its part located just above the level of liquid remaining until it is almost completely emptied , after filling the container 2 with the viscous liquid product to be packaged, such as a liquid detergent and before replacing the draw-off valve 3, an inert gas is injected into the container 2 relative to the packaged product .

a présence de ce gaz au-dessus du niveau du liquide visqueux maintient, à l'intérieur de l'outre 2, une pression légère -suffisante pour réduire considérablement la déformation de sa paroi au cours de son vidage et empêcher, comme illustré sur la figure 2, la formation de plis nuisant à l'écoulement du liquide visqueux qu'elle contient. the presence of this gas above the level of the viscous liquid maintains, inside the flask 2, a slight pressure-sufficient to considerably reduce the deformation of its wall during its emptying and prevent, as illustrated on the Figure 2, the formation of folds affecting the flow of viscous liquid it contains.

La nature du gaz injecté dans l'outre 2 avant remise en place du robinet de soutirage 3 dépend naturellement de la nature du produit visqueux conditionné et, dans de nombreux cas, ce gaz pourra être tout simplement de l'air ou de l'azote. The nature of the gas injected into the bottle 2 before replacing the draw-off valve 3 naturally depends on the nature of the viscous product packaged and, in many cases, this gas may simply be air or nitrogen. .

Par exemple, pour une outre dont la contenance est de 5 litres, la quantité d'azote injectée est de 800 cml sous la pression atmosphérique.  For example, for a bottle with a capacity of 5 liters, the quantity of nitrogen injected is 800 cml under atmospheric pressure.
