Abstract

The invention relates to the manufacture of a plastic packaging bottle 1. A biaxially orientable plastic preform is manufactured. The neck 3 and the handle 4 are injected on the top of this preform. Next, by heating up and drawing (stretching)-blowing, the body 2 is given its final shape, which causes a biaxial orientation of its material. This also rigidly connects it to the end 5 of the handle 4. Application: improvement in the mechanical properties and reduction in the manufacturing cost, since only the body is made from biaxially-orientable quality material.

Description

La présenta invention est relative à une bouteille d'emballage , réalisée en une matière plastique du type dit "bi-orienté " . The present invention relates to a packaging bottle, made of a plastic material of the so-called "bi-oriented" type.

On connaît , par le brevet français 2 494 179 ,un procédé permettant de fabriquer un flacon bi-orisntd à poignée
L'inconvénient de ce dispositif connu résulte notamment de ce que l'ensemble du flacon et du col est réalisé en un seul et meme matériau, Autrement dit le matériau biorientable et relativement coûteux qui est nécessaire pour la fabrication du flacon est egalement utilisé pour fabriquer le col dont le prix de revient se trouve inutilement augmenté.
We know, from French patent 2,494,179, a process for manufacturing a bi-orisntd bottle with handle.
The disadvantage of this known device results in particular from the fact that the whole of the bottle and the neck is made of one and the same material, in other words the biorientable and relatively expensive material which is necessary for the manufacture of the bottle is also used to manufacture the collar whose cost price is unnecessarily increased.

Un autre inconvenient dece dispositif est que le flacon avec sa poignée est fabriqué suivant le procéde du cycle chaud et demande la réalisation dtllne machine spéciale. Another drawback of this device is that the bottle with its handle is produced according to the hot cycle procedure and requires the production of a special machine.

Le développement d'un tel procédé demande la mise en oe- are de de moyens importants difficiles à amortir. The development of such a process requires the implementation of significant means which are difficult to amortize.

La Laprésente invention a pour but d'éviter cet in
convénients, en réalisant en deux étapes une bouteille d'em- ballage dont le corps , et seulement le corps, est réalisé en une matière plastique bi-orientable , tandistandis que les autres parties de la bouteille ( goulot , éventuellement poignée ) sont realisées en un matériau différent et moins cher.
The purpose of the present invention is to avoid this in
Convenient, by making in two stages a packaging bottle whose body, and only the body, is made of a bi-orientable plastic material, while the other parts of the bottle (neck, possibly handle) are made in a different and cheaper material.

Le procédé selon l'invention , pour fabriquer une bouteille dont le corps est en une matière plastique bi-orien tee , est caractérisé en ce que - d'une part , on fabrique par injection d.t.une matière plasti
que bi-orientable , une pré-forme ayant l'aspect général d'
un doigt de gant - tandis que w d'autre part, on injecte par surmoulage sur
l'extrémité ouverte de la pré-forme , et en utilisant une
matière moulable différente , un col ayant la forme défini
tive qui lui est prévue sur la bouteille terminée , la pré
bouteille ainsi obtenue pouvant entre stockée en attente de
reprise pour réchauffage et étirage-soufflage final - alors qu'enfin , dans une opération ultérieurep on procède
au gonflage de la pré-boutaille par étirage et soufflage à
chaud entraînant une bi-orientation de la matière.
The method according to the invention, for manufacturing a bottle, the body of which is made of a two-part plastic tee, is characterized in that - on the one hand, injection is made of a plastic material
that bi-orientable, a preform having the general appearance of
a thermowell - while w, on the other hand, is injected by molding onto
the open end of the preform, and using a
different moldable material, a neck having the defined shape
tive which is provided for him on the finished bottle, the pre
bottle thus obtained which can be stored waiting for
rework for reheating and final stretch-blow molding - while at last, in a subsequent operation, we proceed
inflation of the pre-cut by stretching and blowing at
hot resulting in a bi-orientation of the material.

Suivant une autre caractéristique de l'invention
on effectue un pré-gonflage de la pré-forme en meme temps qu'on injecte par surmoulage X ,par l'extrémité ouverte de la préforme et en utilisant une matière moulable différente ,un col ayant la forme définitive qui lui est prévue sur la bouteille terminée . La pré-bouteille ainsi obtenue peut être stockée en attente de reprise , our le réchauffage et étirage soufflage final.
According to another characteristic of the invention
the preform is pre-inflated at the same time as is injected by overmolding X, through the open end of the preform and using a different moldable material, a neck having the final shape which is provided to it on the bottle finished. The pre-bottle thus obtained can be stored pending recovery, for reheating and final blow-stretching.

Dans les deux cas , ce type de procédé permet- d' utiliser essentiellement des machines existantes standard , dont seuls les outillages sont à adapter à l'invention. In both cases, this type of process makes it possible essentially to use standard existing machines, of which only the tools are to be adapted to the invention.

Suivant une autre caractéristique de 17 in- vention , le col de là bouteille ainsi fabriqué par injection constitue simplement une bague supérieure d'étanchéité , pourvue de moyens pour fixer un bouchon t ces moyens peuvent comporter un dispositif d'accrochage par clipsage , ou un filetage , si l'on utilise un bouchon vissé. According to another characteristic of the invention, the neck of the bottle thus produced by injection simply constitutes an upper sealing ring, provided with means for fixing a stopper. These means may comprise a device for hooking by clipping, or a thread, if a screw cap is used.

Suivant une autre caractéristique de l'invention , le col de la bouteille comporte à la fois une bague supérieure du goulot , et l'extrémité supérieure d'une poignée
Dans ce cas , l'extrémité inférieure de la poignée peut rester libre . Elle peut également se trouver encastrée dans le corps de la bouteille , au moment du soufflage par gonflage final à chaud . <
Suivant une autre caractéristique de l'invention , on utilise , pour le corps et les parois de la bouteille , une matière plastique bi-orientable , choisie parmi les matières suivantes - PET (polyéthylène téréphtalate) - PAN ( polyacrylonitrile) - PP (polypropylène) - PVC ( polychlorure de vinyle).
According to another characteristic of the invention, the neck of the bottle comprises both an upper ring of the neck, and the upper end of a handle
In this case, the lower end of the handle can remain free. It can also be embedded in the body of the bottle, when blowing by final hot inflation. <
According to another characteristic of the invention, a bi-orientable plastic material is chosen for the body and the walls of the bottle, chosen from the following materials - PET (polyethylene terephthalate) - PAN (polyacrylonitrile) - PP (polypropylene) - PVC (polyvinyl chloride).

Suivant une autre caractéristique de-l'invention , la matière choisie pour injecter le col et la poignée éventuelle , est un matériau différent et moins cher,tel que , par exemple , du polypropylène homopolymèreç, ou du polypropylène copolymère. According to another characteristic of the invention, the material chosen to inject the neck and the optional handle, is a different and less expensive material, such as, for example, homopolymer polypropylene, or polypropylene copolymer.

Suivant une autre caracatéristique de l'invention , si la matériau injecté pour le col possède des performances jugées insuffisantes ,notamment en ce qui concerne l'étanchéité aux gaz , on prévoit de faire remonter la matière noble de la pré-forme sur toute la surface interne du col. According to another characteristic of the invention, if the material injected for the neck has performances deemed insufficient, in particular with regard to gas tightness, provision is made to raise the noble material of the preform over the entire surface. internal of the cervix.

On a rrprésenté sur les figures 1 et 2, une bouteille 1 selon l'invention , qui comprend un corps 2 dont le goulot est surmonté par un col 3 équipé d'une poignée 4
Selon l'invention , le col 3 est réalisé d' une pièce en matière plastique injectée , tandis que le corps 2 est en une matière plastique bi-orientée , choisie parmi les matières énoncées ci-dessus ; à savoir : PET , PAN , PP
PVC . Dans l'exemple illustré sur les figures 1 et 2 ,le col 3 est réalisé- d'une pièce avec une poignée 4 qui lui est attachée par son extrémité supérieure .L'extrémité inférieure 5 de la poignée 4 peut rester libre , ou bien être rendue solidaire du corps 2 , au moment de l'opération finale d' étirage et soufflage à chaud , ainsi que cela apparaîtra plus loin
Le col 3 comporte tous les éléments techniques de la bouteille , notamment - un filetage ou des crans d'encliquetage 6 , pour fixer un
bouchon 7 - des éléments d'inviolabilité , tels que des crans 8 , pour
rende inviolable le bouchon 7 , après sa mise en place sur
la bouteille 1 remplie
Au contraire , la matière bi-orientée du corps 2 , permet de réaliser sur celui-ci un gain de poids considérable , tout en lui conférant d'excellentes caractéristiques mécaniques.
There is shown in Figures 1 and 2, a bottle 1 according to the invention, which comprises a body 2 whose neck is surmounted by a neck 3 equipped with a handle 4
According to the invention, the neck 3 is made of a piece of injected plastic, while the body 2 is made of a bi-oriented plastic, chosen from the materials listed above; namely: PET, PAN, PP
PVC. In the example illustrated in FIGS. 1 and 2, the neck 3 is made in one piece with a handle 4 which is attached to it by its upper end. The lower end 5 of the handle 4 can remain free, or else be made integral with the body 2, at the time of the final stretching and hot blowing operation, as will appear below
The neck 3 includes all the technical elements of the bottle, in particular - a thread or snap notches 6, for fixing a
cap 7 - tamper-evident elements, such as notches 8, for
makes the plug 7 inviolable, after it has been placed on
bottle 1 filled
On the contrary, the bi-oriented material of the body 2 allows a considerable weight gain to be achieved thereon, while giving it excellent mechanical characteristics.

Le procédé selon l'invention. consiste dans un premier temps , à fabriquer , par injection d'une matière plastique bi-orientable , une pré-forme 9 (figure 3) ayant l'aspect général d'un doigt de gant . Ensuite , lors d'une opération ultérieure , on injecte , par surmoulage sur l'extrémité ouverte de la pré-forme 9 , et en utilisant une matière moulable différente , un col 3 ayant la forme définitive qui lui est prévue sur la bouteille 1 ( figures 1 , 2 et 3) . Dans l'exemple illustré sur la figure 3 , on a supposé que le col est dépourvu de poignée 4 . On obtient ainsi une pré-bouteille ( figure 3) , qui peut être travaillée immédiatement , ou , au contraire , stockée , en attente de reprise avant de donner naissance à la bouteille 1 finalement désirée. The method according to the invention. consists firstly in manufacturing, by injection of a bi-orientable plastic material, a preform 9 (FIG. 3) having the general appearance of a thermowell. Then, during a subsequent operation, a neck 3 having the final shape which is provided for it on the bottle 1 is injected, by molding onto the open end of the preform 9, and using a different moldable material. Figures 1, 2 and 3). In the example illustrated in FIG. 3, it has been assumed that the neck has no handle 4. This gives a pre-bottle (Figure 3), which can be worked immediately, or, on the contrary, stored, awaiting recovery before giving birth to the bottle 1 finally desired.

Dans une opération ultérieure , on place la pré-bouteille 10 dans un moule de typc connu , dont l'empreinte a la forme définitive de la bouteille 1 , et , dans ce moule, on traite la pré-bouteille 10 préalablement réchauffée , par étirage-soufflage à chaud , jusqu'à lui donner la forme finale de la bouteille 1 .Cette opération de réchauffage et étirage-soufflage entraîne , à la manière connue une bi-orienta tion de la matière du corps 9 tandis que le col 3 reste in- changé / ainsi que son éventuelle poignée 4 0 C'est au cours de cette opération finale ,étirage et soufflage à chaud , que la matière du corps 2 vient s'encastrer autour de l'extrémi té inférieure de la poignée 4 ,lorsqu'on souhaite que cette extrémité 5 soit solidarisée du corps 2 , comme dans ltexem- ple illustré sur les figures 1 et 2. In a subsequent operation, the pre-bottle 10 is placed in a mold of known type, the imprint of which has the final shape of the bottle 1, and, in this mold, the pre-bottle 10, which has been preheated, is treated by stretching. hot blowing, until it gives the final shape of the bottle 1. This reheating and stretch-blowing operation results, in the known manner, in a bi-orientation of the material of the body 9 while the neck 3 remains in - changed / as well as its possible handle 4 0 It is during this final operation, stretching and hot blowing, that the material of the body 2 is embedded around the lower end of the handle 4, when it is desired that this end 5 be secured to the body 2, as in the example illustrated in FIGS. 1 and 2.

Dans la variante illustrée sur les figures 9 a 11 , on place la pré-forme 9 dans un moule d'injection il (figure 9) , pour y injecter par surmoulage , le col 3 et la poignée 4 . cependant , simultanément , on utilise une buse centrale , logée à l'intérieur du noyau 12 de la pré-forme 9 ,ainsi que le fait d'avoir X dans le moule 10 , une em preinte 13 plus grande que les dimensions extérieures de la pré-forme 9 ( figure 9 ) , pour soumettre cette pré-forme 9 à une opération de pré-gonflage ( figure 10). Ainsi , après démoulage , on obtient une pré-bouteille 14 ( figure 11) dont le corps 15 a déjà été soumis à une première opération de pré-gonflage .Comme la pré-bouteille 10 ( figure 3) , la pré-bouteille 14 ( figure 11) peut être stockée en attente de reprise , pour une opération de réchauffage et étiragesoufflage lui conférant sa forme finale correspondant à la bouteille 1 ; figures 1 et 2). In the variant illustrated in FIGS. 9 to 11, the preform 9 is placed in an injection mold 11 (FIG. 9), for injecting therein by overmolding, the neck 3 and the handle 4. however, simultaneously, a central nozzle is used, housed inside the core 12 of the preform 9, as well as the fact of having X in the mold 10, a footprint 13 larger than the external dimensions of the pre-form 9 (Figure 9), to submit this pre-form 9 to a pre-inflation operation (Figure 10). Thus, after demolding, a pre-bottle 14 (FIG. 11) is obtained, the body 15 of which has already been subjected to a first pre-inflation operation. Like the pre-bottle 10 (FIG. 3), the pre-bottle 14 ( Figure 11) can be stored pending recovery, for a reheating and stretch-blowing operation giving it its final shape corresponding to the bottle 1; Figures 1 and 2).

On a représenté sur la figure 12 , une variante possible pour la réalisation de la pré-bouteille 10 Dans ce cas , la pré-forme 9 est surmontée par une jupe 16 , prévue pour tapisser jusqu'en haut la totalité de l'espace intérieur du col 5 . Cette disposition peut équiper aussi bien une pré-bouteille 10 , réalisée à partir de la pré-forme 9 laissée telle quelle , (figure 12) , qu'une pré--bouteille 14 , dont la préforme 9 a été pré-gonflée pour obtenir un corps intermédiaire 15 , du genre illustré sur la figure 11. There is shown in Figure 12, a possible variant for the realization of the pre-bottle 10 In this case, the pre-shape 9 is surmounted by a skirt 16, intended to line the entire interior space to the top of cervix 5. This arrangement can equip both a pre-bottle 10, produced from the pre-form 9 left as it is (FIG. 12), as well as a pre-bottle 14, the preform 9 of which has been pre-inflated to obtain an intermediate body 15, of the type illustrated in FIG. 11.

Dans tous les cas , la présence de la jupe 16 est intéressante , lorsque la matière choisie pour injecter le col 3 possède des performances jugées insuffisantes , notamment en ce qui concerne l'étanchéité aux gaz . On voit que cela permet notamment d'obtenir une bouteille 1 selon 1' invention , utilisable même pour contenir des boissons gazeuses , ce qui n'est généralement pas le cas pour les bouteilles en matière plastique de type connu
Le procédé selon l'invention tel qu'il vient d'être décrit , présente , entre autres , le grand avantage de pouvoir être mis en oeuvre sur des machines standard , existant dejà -, dont seuls les outillages sont à adapter à l ' invention .De telles machines sont illustrées sur les fi coures @ a 8
Il est plus avantageux de faire, sur une première machine , la première phase de moulage de la préforme S à bi-orienter , ainsi que la deuxième phase de surmoulage du col 3 , éventuellement le surmoulage de la poignée du flacon et/ou le prégonflage de la pré-forme 14 . Au cours de la deuxième phase , on recourt au refroidissement com plet de l'ensemble : pré- forme ,col 9 et/ouet/ou éventuellement poignée.
In all cases, the presence of the skirt 16 is advantageous, when the material chosen for injecting the neck 3 has performances deemed insufficient, in particular as regards gas tightness. It can be seen that this makes it possible in particular to obtain a bottle 1 according to the invention, usable even for containing carbonated drinks, which is generally not the case for plastic bottles of known type.
The method according to the invention as just described has, among other things, the great advantage of being able to be implemented on standard machines, already existing -, of which only the tools are to be adapted to the invention .Such machines are illustrated on fi coures @ a 8
It is more advantageous to make, on a first machine, the first phase of molding the preform S to be bi-oriented, as well as the second phase of overmolding of the neck 3, possibly overmolding of the handle of the bottle and / or pre-inflation. of the pre-form 14. During the second phase, use is made of complete cooling of the assembly: preform, neck 9 and / or and / or possibly handle.

Les deux phases d'injection , et éventuellement le pré-gonflage sont réalisés sur une presse horizontale d'injection plastique bi-matière. The two injection phases, and possibly the pre-inflation, are carried out on a horizontal bi-material plastic injection press.

Figure 5 est représentée une presse d'injec- tion bi-matière ,munie de deux unités d'injection 17 et 18, qui injectent à travers le plateau fixe 19 . Une des deux unités d'injection peut# injecter suivant un plan de joint des deux demi-moules 20 et 21 . Dans le cas représenté figure 5, l'unité d'injection 17 doit injecter la pré-forme 9, et 1' unité 18 doit injecter la poignée 4 et/ou le col. FIG. 5 shows a bi-material injection press, provided with two injection units 17 and 18, which inject through the fixed plate 19. One of the two injection units can # inject along a joint plane of the two half-molds 20 and 21. In the case shown in FIG. 5, the injection unit 17 must inject the preform 9, and the unit 18 must inject the handle 4 and / or the neck.

La plateau mobile 22 de la presse étant en position arrière ( figure 5) , le système de fermeture sché matisé par les vérins 23 est en position arrière . Les plaques 21 ont fait un demi-tour par rapport à l'axe de rotation 24 . Le noyau 25 est coiffé de la pré-forme 9 qui vient d' être moulée , et se trouve en position pour le surmoulage. The movable plate 22 of the press being in the rear position (FIG. 5), the dried closure system matified by the jacks 23 is in the rear position. The plates 21 have made a U-turn relative to the axis of rotation 24. The core 25 is capped with the preform 9 which has just been molded, and is in position for overmolding.

Le goulot de la pré-forme 9 destiné à recevoir le surmoulage a été refroidi par un circuit de refroidissement situé dans le noyau 25 0 Quant au corps 9 , il est - soit refroidi , ou en cours de refroidissement si l'on n'en
visage pas de faire à ce poste un pré-gonflage 15 ( figures
10 et 11) - soit à la température moyenne de pré-gonflage.
The neck of the preform 9 intended to receive the overmolding has been cooled by a cooling circuit located in the core 25 0 As for the body 9, it is - either cooled, or in the process of cooling if it is not
face not to make a pre-inflation 15 at this station (Figures
10 and 11) - either at the average pre-inflation temperature.

Les chariots mobiles 26 et 27 sont en position ouverte . Les chariots 26 contiennent plus particulièrement l'empreinte du goulot 3 de la pré-forme 9 ( zone d' accrochage) . Les cnariots 27 contiennent plus particulière ment l'em)#rei nte du col 3 et de son accrochage au goulot et1-ou l'empreinte de la poignée 4
Les unités d'injection 17 et 18 sont en attente après avoir rechargé.
The mobile carriages 26 and 27 are in the open position. The carriages 26 more particularly contain the imprint of the neck 3 of the pre-form 9 (attachment area). The cnariots 27 more particularly contain the em) #rei nte of the neck 3 and its attachment to the neck and 1- or the imprint of the handle 4
The injection units 17 and 18 are on standby after recharging.

La figure 6 représente la fermeture de la presse par l'intérmédiaire des vérins 23 . La fermeture du moule formé des deux demi-moules 20 et 21 est réalisée ainsi que la fermeture des chariots 26 qui viennent coiffer le noyau 25 et la fermeture des chariots 27 qui viennent coiffer le noyau recouvert- de la pré-forme 9
L'unité d'injection 17 injecte alors la préforme 9 suivante , à travers le plateau fixe et le demimoule 20 . Une fois l'injection terminée , s'effectue le refroidissement du goulot ; et le refroidissement ou la régulation thermique pour pré-gonflage du corps de la pré-forme 9.
FIG. 6 represents the closing of the press by means of the jacks 23. The mold formed by the two half-molds 20 and 21 is closed as well as the carriages 26 which cover the core 25 and the carriages 27 which cover the core covered with the preform 9
The injection unit 17 then injects the following preform 9, through the fixed plate and the mold 20. Once the injection is complete, the neck is cooled; and cooling or thermal regulation for pre-inflation of the body of the pre-form 9.

Dès que c'est possible , l'unité d'injection 17 effectue sa phase de plastification , et se met en attente de la prochaine moulée .Simultanément à l'injection de la pré-forme 9 par l'unité dlinjection 17 ,l'unité d'injection 18 injecte Pe col 3 et/ ou la poignée 4 . On entame la phase de refroidissement complet du col 3 et/ou de la poignée 4
Simultanément , soit on continue le refroidissement du corps de la pré-forme 9 ( figures 3 et 12) , soit on effectue le pré-gonflage par une pression d'air amenée à travers le noyau 12 ( figures 9 à 11) , et libéré à travers une soupape 28 située à son extrémité . Dans ces conditions, la paroi de la pré-forme 9 est déformée , pour atteindre la forme pré-gonflée 15 ( figures 10 et 11) de l'enveloppe- La pré-bouteille ainsi obtenue se refroidit complètement dans son moule.
As soon as possible, the injection unit 17 performs its plasticization phase, and waits for the next feed. Simultaneously with the injection of the preform 9 by the injection unit 17, the injection unit 18 injects Pe neck 3 and / or the handle 4. We begin the complete cooling phase of the neck 3 and / or the handle 4
Simultaneously, either the cooling of the body of the preform 9 is continued (Figures 3 and 12), or the pre-inflation is carried out by an air pressure supplied through the core 12 (Figures 9 to 11), and released through a valve 28 located at its end. Under these conditions, the wall of the pre-form 9 is deformed, to reach the pre-inflated form 15 (FIGS. 10 and 11) of the envelope. The pre-bottle thus obtained cools completely in its mold.

La figure 7 montre le moule au moment de 1' ouverture : les chariots 26 et 27 s'écartent , le plateau 22 recule , entraînant le demi-moule 21 et son plateau de fixation 28 au plateau mobile . Le noyau 25 est recouvert de la pré-forme 9 , le noyau voisin est recouvert de la pré-bouteil
le 10 ou 14 .Par un moyen de dévêtissage 7 connu et approprié , la pré-bouteille 10 ou 14 est démoulée et évacuée
soit en vrac , vers un stockage , soit par un manipulateur 29 qui la saisit alors qu'elle est encore sur place sur son noyau 12 et qui , après le dévêtissage , 1' emmène pour la positionner sur un système de transfert 30 , comme représenté sur la figure 8 , pour entamer le cycle de réchauffage, régulation , étirage , soufflage
Une fois le déchargement de la pré-bouteille 10 , ou 14 , effectué , le demi-moule 21 effectue un demi-tour autour de l'axe de rotation 24 (~figure 8) et on retrouve la configuration décrite figure 5 , où le noyau 25 est prêt à un nouveau cycle.
Figure 7 shows the mold at the time of opening: the carriages 26 and 27 move apart, the plate 22 moves back, driving the half-mold 21 and its fixing plate 28 to the movable plate. The core 25 is covered with the preform 9, the neighboring core is covered with the pre-bottle
on 10 or 14. By known and appropriate stripping means 7, the pre-bottle 10 or 14 is removed from the mold and removed
either in bulk, towards storage, or by a manipulator 29 which grasps it while it is still on site on its core 12 and which, after the stripping, takes it to position it on a transfer system 30, as shown in figure 8, to start the heating, regulation, stretching, blowing cycle
Once the pre-bottle 10, or 14 has been unloaded, the half-mold 21 makes a U-turn around the axis of rotation 24 (~ Figure 8) and we find the configuration described in Figure 5, where the core 25 is ready for a new cycle.

Pour des raisons de productivité , on peut créer un moule à trois postes 7 et ne plus cumuler la phase de surmoulage , évetuellement pré-gonflage , avec la phase de déchargement ; dans ces conditions , la rotation est d' un tiers de tour à chaque cycle 7 aux postes de moulage de la pré-forme 9 , et d'obtention de la pré-bouteille 10 ou 14 . On ajoute un poste de déchargement de la pré-bouteille 10 ou 14 , qui se fait alors en temps masqué.  For productivity reasons, it is possible to create a three-station mold 7 and no longer combine the overmolding phase, possibly pre-inflation, with the unloading phase; under these conditions, the rotation is a third of a turn at each cycle 7 at the molding stations of the preform 9, and obtaining the pre-bottle 10 or 14. A post for unloading the pre-bottle 10 or 14 is added, which is then done in masked time.
