Abstract

Hollow blow-moulded containers are provided with prefabricated inserts by supporting the insert in the open mould using struts or cords made of material which is fusible and compatible with the material used for the body of the container. The process is suitable for mfr. of e.g. polyolefin fuel tanks requiring an internal filter (Pj) to protect the fuel outlet, esp. where the position of the insert has to be anchored relative to the moulding wall. The support becomes integral with the moulding wall to avoid the presence of an interface which could leak, unlike tanks containing an insert fitted through a hole cut in the wall of the moulding and requiring a cover to be subsequently secured over the hole.

Description

L'invention se rapporte à un procédé d'obtention d'un corps creux monobloc réalisé par l'expansion d'une paraison de matière thermoplastique selon un procédé de soufflage (par exemple : extrusion-soufflage ou injection-soufflage) ledit corps étant pourvu d'une pièce additive sur l'une de ses parois intérieures. The invention relates to a process for obtaining a one-piece hollow body produced by the expansion of a parison of thermoplastic material according to a blowing process (for example: extrusion blow molding or injection blow molding), said body being provided an additive piece on one of its interior walls.

Pour de nombreuses applications, il est nécessaire de disposer d'une pièce additive à l'intérieur d'un corps creux, cette partie saillante ayant une fonction, soit qui lui est propre, soit devant constituer un point d'attachement et de liaison à ladite paroi, d'un organe rapporté. For many applications, it is necessary to have an additive part inside a hollow body, this projecting part having a function, either specific to it, or having to constitute a point of attachment and connection to said wall, of an added member.

Quand le corps creux est formé à partir de deux coquilles ou deux elements complémentaires assemblés (comme c'est le cas pour les reservoirs métalliques emboutis ou les reservoirs en matière moulée par injection) il est aisé de procéder à la mise en place d'une pièce additive constituant la partie saillante désirée, et de la fixer à l'intérieur d'une des coquilles avant l'assemblage de fermeture. When the hollow body is formed from two shells or two complementary elements assembled (as is the case for deep-drawn metal tanks or tanks made of injection molded material) it is easy to install a additive part constituting the desired projecting part, and fix it inside one of the shells before the closure assembly.

Il ne peut en être ainsi dans le cas de réservoirs réalisés en une seule piéce, par exemple, par expansion d'une paraison creuse en matière thermo-plastique ramollie, pour autant que les dimensions de la piéce additive- ne permettent pas son introduction à l'intérieur du corps creux par un de ces orifices naturels. This cannot be so in the case of reservoirs produced in a single piece, for example, by expansion of a hollow parison made of softened thermo-plastic material, provided that the dimensions of the additive piece do not allow its introduction to the interior of the hollow body by one of these natural orifices.

On a déjà proposé, dans ce cas (par exemple par le brevet français
KAUTEX n0 1.317.649) de placer la pièce additive dans le moule avant soufflage, en la tenant espacée des parois de la paraison, au moyen d'un support ou mandrin rétractable. Il reste, alors, à procéder, après soufflage, à la fixation de cette pièce additive, à la paroi intérieure.We have already proposed, in this case (for example by the French patent
KAUTEX n0 1.317.649) to place the additive part in the mold before blowing, keeping it spaced from the walls of the parison, by means of a support or retractable mandrel. It remains, then, to proceed, after blowing, to the fixing of this additive part, to the interior wall.

Dans tous les cas connus (KAUTEX précité) cette fixation s'effectue en utilisant un trou percé au travers de cette paroi ou le trou laissé par le retrait du mandrin. In all known cases (KAUTEX cited above), this fixing is carried out using a hole drilled through this wall or the hole left by the withdrawal of the mandrel.

Or, très souvent, le corps creux est destiné à servir de réservoir qui, par fonction, doit être étanche. Nul ne peut se porter garant de l'étanchéité réalisée autour de la fixation de la pièce passé au travers de la paroi, pas plus que d'une obturation du trou laissé par le mandrin. However, very often, the hollow body is intended to serve as a reservoir which, by function, must be sealed. No one can vouch for the seal created around the fixing of the part passed through the wall, no more than a sealing of the hole left by the mandrel.

Ce risque est inadmissible, "a fortiori" lorsque le réservoir est celui devant contenir un corps liquide inflammable. This risk is unacceptable, "a fortiori" when the tank is the one that must contain a flammable liquid body.

L'invention apporte des solutions satisfaisantes au problème de la fixation d'une pièce additive à l'intérieur d'un corps creux réalisé en une seule pièce par expansion d'une paraison creuse en matière tbertno- plastique ramollie par application d'un procédé de soufflage même si ce corps creux est un réservoir, puisqu'aucun perçage de la paroi n'est nécessaire. The invention provides satisfactory solutions to the problem of fixing an additive part inside a hollow body produced in one piece by expansion of a hollow parison made of softened tbertnoplastic material by application of a process. even if this hollow body is a reservoir, since no drilling of the wall is necessary.

Ces solutions s'inspirent, toutes, du principe connu du soufflage de la paraison alors que la pièce additive est maintenue entre les coquilles du moule, mais se particularise par le fait que son support ne laisse aucune trace dans la paroi du corps creux. These solutions are all inspired by the known principle of blowing the parison while the additive part is held between the mold shells, but is distinguished by the fact that its support leaves no trace in the wall of the hollow body.

Selon l'invention, l'extrèmité de ce support opposée à celle portant la pièce additive se termine par un insert, préalablement réalisé en un matériau thermo-plastique dont la nature est identique ou compatible avec celle du corps creux, pour qutaprès surmoulage de cet insert par la paroi de ce dernier, il y ait une cohésion intermoléculaire des matériaux, telle que paroi et insert fassent bloc. According to the invention, the end of this support opposite to that carrying the additive piece ends with an insert, previously made of a thermo-plastic material whose nature is identical or compatible with that of the hollow body, for four times after molding of this insert through the wall of the latter, there is an intermolecular cohesion of the materials, such that wall and insert form a block.

D'autres particularités et avantagesapparattront à la lecture de la description et des revendications qui vont suivre, lesquelles sont faites en regard des dessins annexés sur lesquels
Les figures 1 et 2 représentent, à titre d'exemple, une pièce additive respectivement en élévation et plan.Other features and advantages will appear on reading the description and the claims which follow, which are made with reference to the appended drawings in which
Figures 1 and 2 show, by way of example, an additive part respectively in elevation and plane.

La figure 3 montre la phase préliminaire au soufflage après introduction de la piéce additive à l'intérieur du moule de soufflage, selon un premier mode de réalisation, tandis que la figure 4 se rapporte à la phase ultérieure au soufflage. FIG. 3 shows the preliminary phase of blowing after introduction of the additive piece inside the blowing mold, according to a first embodiment, while FIG. 4 relates to the phase subsequent to blowing.

La figure 10 illustre ce clipsage. Figure 10 illustrates this clipping.

La figure 11 montre an autre mode de fixation basé sur la rétention magnètique. Figure 11 shows another method of attachment based on magnetic retention.

A titre d'exemple descriptif, il a été choisi le cas de la fixation d'une pièce additive PJ devant constituer un "piège" pour carburant dans un réservoir R. Cette pièce additive comporte une semelle PS sur laquelle font saillies les cloisons PC. By way of a descriptive example, the case has been chosen of fixing an additive part PJ which must constitute a "trap" for fuel in a tank R. This additive part comprises a soleplate PS on which the partitions PC protrude.

Selon une première forme d'application du procédé, objet des présentes, la pièce additive PJ préétablie, est placée à l'extrémité libre Tla d'une tige rigide T1, elle-même, préalablement réalisée et dont: la seconde extrémité est solidaire d'un insert Tlb. Commodément, la pièce additive PJ est percée d'un trou central Po destiné à être enfilé sur l'extrémité Tla.  According to a first form of application of the method, object of the present, the additive part PJ preset, is placed at the free end Tla of a rigid rod T1, itself, previously produced and of which: the second end is integral with 'a Tlb insert. Conveniently, the additive part PJ is pierced with a central hole Po intended to be threaded on the end Tla.

L'insert Tlb peut, soit faire partie intégrante de la tige T1, soit être pourvu d'un emmanchement provisoire de cette tige. The insert Tlb can either be an integral part of the rod T1, or be provided with a temporary fitting of this rod.

S'il fait corps avec la tige, celle-ci restera présente après soufflage, dans le cas contraire, elle pourra être enlevée sitôt sa fonction de support terminée. If it is integral with the rod, it will remain present after blowing, otherwise, it can be removed as soon as its support function is completed.

que
Quellevsoit la solution choisie, la matière constituant cet insert Tlb est de même nature que celle du corps creux ou, tout au moins, d'une nature compatible avec cette dernière pour qu'après sur moulage, il y ait une véritable cohésion intermoléculaire.than
Whatever the solution chosen, the material constituting this Tlb insert is of the same nature as that of the hollow body or, at least, of a nature compatible with the latter so that after molding, there is a true intermolecular cohesion.

L'insert Tlb est prolongé par une queue Q qui sert à sa fixation par rapport aux coquilles du moule Mo afin de permettre le centrage de la tige T1 et de la pièce PJ, à l'intérieur de la paraison creuse PA(figure 3). The insert Tlb is extended by a tail Q which is used for its fixing relative to the shells of the mold Mo in order to allow the centering of the rod T1 and of the part PJ, inside the hollow parison PA (FIG. 3) .

Comme on le voit sur les figures 4 et 5, après soufflage, l'insert
Tlb fait bloc avec la paroi du réservoir R.As seen in Figures 4 and 5, after blowing, the insert
Tlb forms a block with the wall of the reservoir R.

Selon une variante de cette forme de réalisation du procédé, la pièce additive PJ est solidaire de deux fils Fl et F2 tendus et passant dans des encoches des coquilles Mol et Mo2.
Ces fils sont en une matière thermo-plastique de meme nature que celle du corps creux, ou tout au moins, d'une nature compatible avec cette der nière pour qu'après surmoulage, il y ait une véritable cohésion intermoléculaire entre fils et parois.According to a variant of this embodiment of the method, the additive part PJ is integral with two wires F1 and F2 stretched and passing in notches of the shells Mol and Mo2.
These wires are made of a thermoplastic material of the same nature as that of the hollow body, or at least of a nature compatible with the latter so that after overmolding, there is a true intermolecular cohesion between wires and walls.

Bien entendu, on peut envisager d'utiliser plusieurs fils disposés en haubans. Of course, one can consider using several wires arranged in shrouds.

Aprés soufflage, on libère de ses fils supports, la pièce additive
PJ pour la fixer à la paroi intérieure R.After blowing, the additive part is freed from its supporting wires
PJ to fix it to the interior wall R.

Quel que soit le mode de support de la pièce additive avant souffla- ge, il y a lieu d'assurer sa fixation après soufflage. Whatever the mode of support of the additive part before blowing, it must be secured after blowing.

Divers moyens peuvent être envisagés, mais tous ont un point commun : ils ne nécessitent aucun perçage de la paroi contre laquelle la pièce additive doit être fixée. Various means can be envisaged, but all have one thing in common: they do not require any drilling of the wall against which the additive part must be fixed.

Il peut y avoir collage, soudure à haute fréquence, soudure par ultra-sons, clipsage, fixation magnétique. There may be bonding, high frequency welding, ultrasonic welding, clipping, magnetic fixing.

Pour réaliser ces types de fixation, on introduit un outil par un des orifices naturels OV du corps creux, de manière que son extrémité travaillante vienne appliquer contre la pièce additive PJ en sa position de fixation. To achieve these types of fixing, a tool is introduced through one of the natural orifices OV of the hollow body, so that its working end comes to apply against the additive part PJ in its fixing position.

Sur la figure 5, on voit l'outil (ici une sonotrode SO) pressant la pièce PJ contre la paroi, de l'autre coté de laquelle se trouve l'enclume EC. In Figure 5, we see the tool (here a SO sonotrode) pressing the part PJ against the wall, on the other side of which is the anvil EC.

Si la pièce additive PJ est pourvue de pattes telles que PP (fig. 8 et fig. 9) ou d'une plate-bande périphérique, elle peut être clipsée par poussée par un outil, entré par un orifice naturel, dans un logement R1 obtenu par déformation de la paroi du corps creux (fig. 10). If the additive part PJ is provided with tabs such as PP (fig. 8 and fig. 9) or with a peripheral strip, it can be clipped by pushing by a tool, entered by a natural orifice, into a housing R1 obtained by deformation of the wall of the hollow body (fig. 10).

Enfin, si l'on noie dans cette paroi, une pièce magnétique MM à la manière d'un insert extérieur, on peut assurer la fixation de PJ par simple aimantation, si la pièce PJ est solidaire d'un aimant. Bien entendu, l'aimant peut-être placé à l'extérieur de la paroi et la pièce magnétique à l'intérieur, ce qui serait le cas selon lequel la pièce additive est totalement en fer.  Finally, if one drowns in this wall, a magnetic part MM in the manner of an external insert, one can ensure the fixing of PJ by simple magnetization, if the part PJ is integral with a magnet. Of course, the magnet can be placed outside the wall and the magnetic part inside, which would be the case where the additive part is completely made of iron.
