Ce problème est résolu conformément à l'invention à l'aide d'un procédé pour fabriquer un fût en matiere thermoplastique par formage par soufflage, dans un moule de soufflage formé de deux éléments et pouvant être fermé par une soudure en bout, ce fût comportant une enveloppe, des fonds ainsi que des rouleaux formés par façonnage dans la zone de jonction entre l'enveloppe et les fonds, et possédant deux bondes disposées dans la partie marginale au niveau de la soudure en bout du moule de soufflage, caractérisé en ce que l'une de ces bondes est réalisée sous la forme d'une  This problem is solved according to the invention by means of a process for manufacturing a barrel of thermoplastic material by blow molding, in a blow mold formed of two elements and which can be closed by a butt weld, this barrel having an envelope, bottoms and shaped rollers in the junction area between the envelope and the bottoms, and having two bungs disposed in the marginal portion at the end weld of the blow mold, characterized in that that one of these bungs is made in the form of a

L'invention est basée sur le fait que le procédé décrit plus haut peut être également appliqué avantageusement à la fabrication de fûts comportant seulement deux bondes. On obtient même une amélioration particulièrement importante de la rigidité de forme au voisinage de la bonde de vidage complet, étant donné que le bossage est préformé dans la zone de la soudure en bout du moule de soufflage formé de deux éléments et que dans cette zone, le tuyau devant être gonflé par soufflage est pincé en fonction du contour du bossage. Ceci conduit au fait que, lors du formage, la déformation par soufflage n'est que faible et que le collet de la bonde possède une épaisseur de paroi relativement  The invention is based on the fact that the process described above can also be advantageously applied to the manufacture of barrels with only two bungs. Even a particularly significant improvement in the form stiffness is obtained in the vicinity of the complete emptying plug, since the boss is preformed in the region of the end weld of the blow mold formed of two elements and that in this zone, the pipe to be inflated by blow is pinched according to the contour of the boss. This leads to the fact that, during forming, the deformation by blowing is only weak and that the neck of the bung has a relatively thick wall

This contributes in a surprisingly effective way to obtaining rigidity of form. The stiffness of shape is further increased by the fitting

La description qui va suivre, en regard des des-  The description that follows, with regard to the

La figure 1 représente une vue en plan d'un fût réalisé en une matière thermoplastique et qui a été fabriqué  The accompanying drawings, by way of non-limiting examples, will make it possible to understand how the invention can be put into practice.

A partir de l'observation comparée des figures 1 et 2, on voit que, pour ce qui concerne le fût fabriqué 1,  From the comparative observation of FIGS. 1 and 2, it can be seen that, as regards the manufactured drum 1,

La bonde de droite est réalisée sous la forme d'une bonde 6 de vidage complet. Le fût a été fabriqué par  4 formed in the junction zone between the envelope 2 of the fat and the funds 3 of the latter, and has, in at least one bottom, that is to say the upper bottom 3 of the drum in the example embodiment, two collars 5, 6 located in the marginal zone in the vicinity of the end weld of the blow mold. The right bung is made in the form of a bung 6 complete emptying. The drum was manufactured by

Lorsqu'on considère de façon comparée les figures 3 à 5, on voit que, lors de l'opération de soufflage, on a formé, dans le fond 3 du fût, un bossage cylindrique 7 se raccordant à l'enveloppe 2 du fût (voir figure 4) . Après démoulage du fût et refroidissement suffisant de ce dernier, on a éliminé la tête du bossage 7, comme le montre la figure 5. Le collet 8 de la bonde subsiste. Si on considère la figure 3, qui représente une partie du fût terminé, on voit qu'un raccord fileté préformé 9 de.la bonde, équipé d'un élément en forme de manchon 10, a été soudé sur le collet 8 de la bonde. De cette manière on obtient, au niveau de la bonde 6 de vidage complet, des conditions statiques et de solidité, qui améliorent avantageusement la rigidité de la  When it is considered in a manner compared with FIGS. 3 to 5, it can be seen that, during the blowing operation, a cylindrical boss 7, connected to the casing shell 2, has been formed in the bottom 3 of the barrel ( see Figure 4). After demolding the drum and sufficient cooling of the latter, the boss was removed from the boss 7, as shown in Figure 5. The collar 8 of the bung remains. Referring to FIG. 3, which shows part of the completed bole, it will be seen that a preformed threaded connection 9 of the bung, equipped with a sleeve-like element 10, has been welded to the collar 8 of the bung . In this way, at the complete drain valve 6, static conditions and solidity are obtained, which advantageously improve the rigidity of the
