Description

TUBE EN MATIERE PLASTIQUE POUR LE CONDITIONNEMENT DE PRODUITS PATEUX
OU SIMILAIRES ET SON PROCEDE DE FABRICATION
L'invention a pour objet un tube en matière plastique pour le conditionnement de produits pâteux ou similaires et son procédé de fabrication.
PLASTIC TUBE FOR PACKAGING PASTA PRODUCTS
OR SIMILAR AND METHOD OF MANUFACTURING SAME
The subject of the invention is a plastic tube for the packaging of pasty or similar products and its manufacturing process.

Dans de nombreux domaines, il est courant de conditionner les produits en pâte ou en crème dans des tubes en matière thermoplastique. I1 en est ainsi par exemple pour les produits de beauté, les crèmes solaires... In many fields, it is common to package dough or cream products in tubes made of thermoplastic material. This is the case for example for beauty products, sunscreens, etc.

Ces tubes sont composés de deux éléments : un corps cylindrique constitué en matière plastique extrudée et un embout qui, constitué en matière plastique injectée, comporte un col fileté et une embase annulaire fixée par soudure sur l'une des extrémités du corps. A ce tube est associé un bouchon fileté coopérant avec le col précité. Quant au remplissage du tube, il se fait au travers de son extrémité ouverte , et après son remplissage le tube est fermé par pincement et soudure sur elle-même de cette extrémité. These tubes are composed of two elements: a cylindrical body made of extruded plastic and a nozzle which, made of injected plastic, has a threaded neck and an annular base fixed by welding on one end of the body. To this tube is associated a threaded plug cooperating with the aforementioned neck. As for the filling of the tube, it is done through its open end, and after filling the tube is closed by pinching and welding on itself of this end.

La fabrication de ces tubes est relativement simple, mais présente l'inconvénient de nécessiter d'abord deux opérations indépendantes : un montage du corps tubulaire par extrusion, et un moulage de l'embout par injection, puis une troisième opération de soudure pour assembler le corps et l'embout. The manufacture of these tubes is relatively simple, but has the drawback of first requiring two independent operations: mounting the tubular body by extrusion, and molding the nozzle by injection, then a third welding operation to assemble the body and mouthpiece.

Pour écarter cet inconvénient, l'invention propose d'appliquer à la fabrication de ces tubes le procédé connu de fabrication de flacons en matière plastique par soufflage, procédé grâce auquel il est possible d'obtenir en une seule opération de moulage à la fois le corps et le col d'un récipient. L'application de ce procédé au cas particulier de flacons de faible diamètre, destinés à devenir des tubes, pose toutefois un problème. Il s'agit de l'impression des divers signes distinctifs et des indications qui doivent apparaître sur le tube, impression qui ne peut être réalisée que sur les zones du tube dans lesquelles n'apparaissent pas deux fines nervures correspondant au plan de joint des deux éléments du moule ayant servi à la fabrication du tube. To overcome this drawback, the invention proposes to apply to the manufacture of these tubes the known method of manufacturing plastic bottles by blowing, a process by which it is possible to obtain in a single molding operation both the body and neck of a container. The application of this process to the particular case of small diameter bottles, intended to become tubes, poses a problem, however. These are the printing of the various distinctive signs and the indications which must appear on the tube, an impression which can only be carried out on the zones of the tube in which two fine ribs do not appear corresponding to the joint plane of the two. elements of the mold used to manufacture the tube.

L'invention résoud ce problème. Elle a pour objet un tube en matière plastique qui, réalisé par soufflage, comporte venant de moulage dans l'embase de son col, au moins une oreille ultérieurement utilisable pour le positionnement automatique du tube sur une machine à imprimer. The invention solves this problem. It relates to a plastic tube which, produced by blowing, comprises coming from molding in the base of its neck, at least one ear subsequently usable for the automatic positioning of the tube on a printing machine.

Cette oreille peut apparaître en relief ou en creux sur la face extérieure de l'embase du col. This ear may appear in relief or hollow on the outside of the base of the neck.

L'invention sera bien comprise d'ailleurs à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution d'un tube fabriqué selon ce procédé
Figure 1 en est une vue en perspective,
Figure 2 en est, à plus grande échelle, une vue en élévation immédiatement après son moulage,
Figure 3 en est une vue en coupe transversale suivant 3/3 de figure 1
Et Figure 4 en est une vue en élévation après sectionnement de son extrémité inférieure.
The invention will be understood moreover with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of a tube manufactured according to this process
Figure 1 is a perspective view,
Figure 2 is an enlarged view immediately in elevation after molding,
Figure 3 is a cross-sectional view along 3/3 of Figure 1
And Figure 4 is an elevational view thereof after sectioning its lower end.

Comme le montre la figure 1, le tube qui fait l'objet de l'invention présente finalement un aspect habituel car il est composé d'un corps creux (1) dont la partie inférieure (2) est refermée sur elle-même par écrasement et par soudure et dont la partie supérieure (3) consiste en une embase de forme générale tronconique se poursuivant vers le haut par un col fileté recevant un bouchon vissé (4). As shown in Figure 1, the tube which is the subject of the invention finally has a usual appearance because it is composed of a hollow body (1) whose lower part (2) is closed on itself by crushing and by welding and whose upper part (3) consists of a generally frustoconical base continuing upwards by a threaded neck receiving a screw cap (4).

L'originalité de ce tube réside dans son procédé de fabrication et dans un agencement particulier qui est nécesaire pour son impression par suite de la mise en oeuvre de ce procédé de fabrication. The originality of this tube lies in its manufacturing process and in a particular arrangement which is necessary for its printing as a result of the implementation of this manufacturing process.

Ce tube est en effet fabriqué par soufflage d'une paraison de matière plastique à l'intérieur d'un moule composé de deux éléments complémentaires se raccordant suivant un plan de joint passant -par l'axe du tube à fabriquer. En donnant aux deux éléments du moule la forme et les dimensions recherchées pour le tube, il est ainsi possible d'obtenir un tube cylindrique (5) visible aux figures 2, 3 et 4. Ce tube (5) correspond au corps (1) du tube de figure 1 ; et ce tube (5) qui est fermé à son extrémité inférieure par un fond (6) se termine à son extrémité supérieure par l'embase tronconique (3) laquelle se prolonge vers le haut par un col fileté (7) destiné à recevoir le bouchon de fermeture (4). This tube is in fact manufactured by blowing a parison of plastic material inside a mold composed of two complementary elements connecting along a joint plane passing through the axis of the tube to be manufactured. By giving the two mold elements the desired shape and dimensions for the tube, it is thus possible to obtain a cylindrical tube (5) visible in Figures 2, 3 and 4. This tube (5) corresponds to the body (1) the tube of Figure 1; and this tube (5) which is closed at its lower end by a bottom (6) ends at its upper end by the frustoconical base (3) which is extended upwards by a threaded neck (7) intended to receive the closure cap (4).

L'ensemble du tube est donc fabriqué par soufflage en une seule pièce ; et il comporte, venant de moulage, deux oreilles (8) qui apparaissent diamétralement opposées l'une par rapport à l'autre sur la face supérieure de l'embase tronconique (3) constituant l'extré- mité supérieure du tube. The entire tube is therefore produced by blowing in one piece; and it comprises, coming from molding, two ears (8) which appear diametrically opposite one with respect to the other on the upper face of the frustoconical base (3) constituting the upper end of the tube.

Lorsque le tube a ainsi été fabriqué, il est ensuite soumis à une opération de sectionnement de sa zone inférieure (9) et ce comme le montre la figure 4. When the tube has thus been manufactured, it is then subjected to a sectioning operation of its lower zone (9) and this as shown in FIG. 4.

Le tube est ainsi ouvert à sa partie inférieure ; et c'est grâce à cette ouverture que le tube, après avoir été fermé par son bouchon (4), est rempli en un produit pâteaux ou crémeux. Après son remplissage, le tube (5) est définitivement fermé à son extrémité inférieure par pincement et soudure de celle-ci sur elle-même, comme cela est visible en (2) à la figure 1.The tube is thus open at its lower part; and it is thanks to this opening that the tube, after being closed by its cap (4), is filled with a pastry or creamy product. After its filling, the tube (5) is definitively closed at its lower end by pinching and welding it on itself, as can be seen in (2) in FIG. 1.

I1 est toutefois à remarquer, et cela est un avantage important résultant de l'invention, que si le tube doit recevoir des signes distinctifs ou des indications quelconques par une opération d'impression sur une machine appropriée, cette opération ne pose pas de problème particulier. Cela résulte de la présence des oreilles (8) qui, prévues à la partie supérieure du tube, à savoir dans son embase (3), permettent un positionnement automatique du tube sur la machine à imprimer. It should however be noted, and this is an important advantage resulting from the invention, that if the tube is to receive distinctive signs or any indications by a printing operation on an appropriate machine, this operation does not pose any particular problem. . This results from the presence of the ears (8) which, provided at the upper part of the tube, namely in its base (3), allow automatic positioning of the tube on the printing machine.

Grâce à ce positionnement automatique, il est possible d'avoir la certitude que l'impression du tube se fera dans l'une ou dans l'autre ou à la fois dans l'une et dans l'autre des deux zones du tube séparées par les deux fines nervures longitudinales (10) qui apparaissent de façon diamétralement opposée sur le corps du tube et résultent du plan de joint du moule.Thanks to this automatic positioning, it is possible to have the certainty that the printing of the tube will be done in one or the other or both in one and in the other of the two zones of the separate tube by the two fine longitudinal ribs (10) which appear diametrically opposite on the body of the tube and result from the joint plane of the mold.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce tube de matière plastique qui a été ci-dessus indiquée à titre d'exemple; elle en embrasse au contraire toutes les variantes quels que soient notamment la nature de la matière constituant le tube, ainsi que la position, la forme et le caractère positif ou négatif des oreilles prévues sur l'embase du tube afin de permettre son positionnement sur une machine à imprimer.  It goes without saying that the invention is not limited to the sole embodiment of this plastic tube which has been indicated above by way of example; on the contrary, it embraces all the variants thereof, whatever the nature of the material constituting the tube, as well as the position, the shape and the positive or negative character of the ears provided on the base of the tube in order to allow its positioning on a printing machine.
