Description

EMBALLAGES POUR MATERIAUX SE PRESENTANT SOUS FORME DE PATES OU
SE TRANSFORMANT EN PATES SOUS L'EFFET DE LA CHALEUR
L'invention concerne des emballages pour des matériaux se présentant sous forme de pâtes ou se ramollissant sous l'action de la chaleur en formant une pâte.PACKAGES FOR MATERIALS IN THE FORM OF PASTA OR
TRANSFORMING INTO PASTA UNDER THE EFFECT OF HEAT
The invention relates to packages for materials in the form of pastes or softening under the action of heat to form a paste.

Elle vise plus particulièrement des emballages pour mélanges de matières hydrocarbonées couramment appelées bitumes. It relates more particularly to packaging for mixtures of hydrocarbon materials commonly called bitumens.

De manière habituelle, le bitume est emballé dans des fûts en acier. Mais avec l'augmentation croissante du coût de l'acier, le prix d'un fût est actuellement plus élevé que la valeur du bitume qu'il contient. Le problème du remplacement des fûts en acier par d'autres emballages plus économiques s'avère donc nécessaire. Bitumen is usually packaged in steel drums. But with the increasing cost of steel, the price of a barrel is currently higher than the value of the bitumen it contains. The problem of replacing steel drums with other more economical packaging is therefore necessary.

Plusieurs tentatives ont été effectuées dans le passé avec des matériaux tels que des sacs en matières plastiques, plus spécialement à base de polyamide. Cependant sous les climats chauds, le ramollissement du bitume entraîne la rupture des soudures des sacs provoquant l'écoulement du bitume. Several attempts have been made in the past with materials such as plastic bags, more particularly based on polyamide. However in hot climates, the softening of the bitumen leads to the rupture of the welds of the bags causing the flow of the bitumen.

L'un des emballages les plus appropriés à cet égard se présente sous forme d'une gaine de polyamide couramment utilisée en charcuterie pour emballer des saucisses ou analogues. Toutefois cet emballage ne convient que sous les climats froids ou tempérés tel que l'Allemagne et ne peut être utilisé sous les climats chauds où les températures élevées durent plusieurs semaines. One of the most suitable packaging in this respect is in the form of a polyamide sheath commonly used in cured meats for packaging sausages or the like. However, this packaging is only suitable in cold or temperate climates such as Germany and cannot be used in hot climates where the high temperatures last several weeks.

Pour résoudre ces problèmes techniques, l'inventeur a recherché des moyens permettant d'assurer une fermeture efficace résistant à tout climat, conduisant ainsi à l'élaboration de nouvelles structures d'emballages pour les matières en question.  To solve these technical problems, the inventor sought means to ensure an effective closure resistant to any climate, thus leading to the development of new packaging structures for the materials in question.

L'invention a donc pour but de fournir de nouveaux emballages pour des matériaux se présentant sous forme de pâtes ou susceptibles de se ramollir sous l'effet de la chaleur, plus économiques que l'emballage traditionnel et utilisables sous tout climat. The invention therefore aims to provide new packaging for materials in the form of pastes or likely to soften under the effect of heat, more economical than traditional packaging and usable in any climate.

Les emballages selon l'invention sont caractérisés en ce qu'ils sont élaborés à partir d'un matériau de renforcement naturel ou synthétique tissé et d'un film de matière thermoplastique sensiblement de même dimension. The packages according to the invention are characterized in that they are produced from a woven natural or synthetic reinforcing material and a film of thermoplastic material substantially of the same size.

On observera que le matériau tissé assure la solidité et la souplesse de la structure tandis que le film plastique permet de garantir l'étanchéité
Selon une disposition préférée de l'invention le film en matière plastique est appliqué par extrusion sur le matériau de renforcement tissé.It will be observed that the woven material ensures the solidity and the flexibility of the structure while the plastic film makes it possible to guarantee the sealing
According to a preferred arrangement of the invention, the plastic film is applied by extrusion to the woven reinforcement material.

En variante, le film en matière plastique se présente sous forme de gaine et constitue une doublure à l'intérieur du matériau tissé. Alternatively, the plastic film is in the form of a sheath and constitutes a lining inside the woven material.

On notera que le terme film, tel qu'utilisé dans la description et les revendications, couvre aussi bien une pellicule de matière plastique que plusieurs pellicules laminées ensemble. It will be noted that the term film, as used in the description and the claims, covers both a plastic film and several films laminated together.

De manière avantageuse, le matériau de renforcement forme une toile en une matière naturelle telle que le jute ou le raphia, ou en une matière plastique comme le polypropylène. Advantageously, the reinforcing material forms a fabric in a natural material such as jute or raffia, or in a plastic material such as polypropylene.

Selon une autre disposition avantageuse de l'invention, le film en matière thermoplastique est à base d'un polyamide. According to another advantageous arrangement of the invention, the film of thermoplastic material is based on a polyamide.

Lorsque ce film est appliqué par extrusion sur le matériau de renforcement, on ferme l'emballage et on le scelle par couture pour former un sac capable de maintenir et contenir la pression de la pâte, lorsqu'elle se ramollit sous l'effet de la chaleur. When this film is applied by extrusion to the reinforcing material, the package is closed and sealed by sewing to form a bag capable of maintaining and containing the pressure of the dough, when it softens under the effect of the heat.

Les emballages de l'invention renferment avantageusement, en tant que matériau formant une pâte, du bitume ou des composés du type du bitume tels que les mélasses. The packages of the invention advantageously contain, as a material forming a paste, bitumen or compounds of the bitumen type such as molasses.

Lorsque le film plastique constitue une doublure, on ferme le sac d'emballage en le scellant, de manière étanche, puis en cousant le matériau de renforcement tissé de manière à former une couture résistant à la pression de la pâte qu'il contient. When the plastic film constitutes a lining, the packaging bag is closed by sealing it tightly, then sewing the woven reinforcement material so as to form a pressure-resistant seam of the dough which it contains.

Conformément à l'invention, on effectue le remplissage des sacs, gaines, ou analogues, utilisés comme emballages, en les maintenant dans un bain d'eau froide sous une station de remplissage des matériaux sous forme de pâte, ou susceptibles de se transformer en pâtes sous l'effet de la chaleur. Leur maintien dans un bain d'eau froide permet au matériau introduit de se refroidir instantanément. Lorsque le refroidissement est complet on ferme les sacs de manière étanche en opérant avantageusement comme indiqué plus haut. In accordance with the invention, the bags, sheaths or the like used for packaging are filled, keeping them in a cold water bath under a filling station for materials in the form of paste, or capable of being transformed into pasta under the effect of heat. Keeping them in a cold water bath allows the material introduced to cool instantly. When the cooling is complete, the bags are closed in a sealed manner, operating advantageously as indicated above.

La taille des sacs recommandée est celle des sacs normalement utilisés dans les pays chauds. The recommended bag size is that of the bags normally used in hot countries.

On mesurera l'intérêt de ces emballages sous les climats tropicaux et particulièrement dans les pays en voie de développement. Ils permettent en effet le transport et le stockage de matériaux en particulier de bitume ou de composés du type du bitume comme les mélasses, sous une forme économique, sans les inconvénients d'écoulement de matière des emballages proposés à ce jour.  We will measure the interest of this packaging in tropical climates and particularly in developing countries. They allow the transport and storage of materials, in particular bitumen or bitumen-type compounds such as molasses, in an economical form, without the drawbacks of material flow from the packaging offered to date.
