Abstract

Method of coating a bottle 1, for example a glass bottle, with a plastic film using a machine for injecting the plastic, consisting in positioning the bottle 1 around a punch 2 of an injection station of the machine and in surrounding the bottle with an injection mould 4, then in injecting the plastic around the bottle and blowing a pressurised fluid inside the bottle synchronously with the injection of plastic.

Description

La présente invention concerne un procédé de revêtement d'un flacon d'une pellicule en matière plastique, une machine destinée à mettre en oeuvre le procédé ainsi que le flacon revêtu obtenu par ce procédé. The present invention relates to a method for coating a vial with plastic film, a machine intended to carry out the method as well as the coated vial obtained by this method.

On connaît un tel procédé, par exemple pour revêtir des flacons en verre, notamment du type aérosol, par une pellicule en matière plastique constituée de polychlorure de vinyl ou PVC. Such a process is known, for example for coating glass bottles, in particular of the aerosol type, with a plastic film made of polyvinyl chloride or PVC.

Un tel revêtement est réalisé par trempage dans une émulsion contenant un plastifiant. Après trempage l'émulsion est cassée et le plastifiant absorbé, par chauffage. Such a coating is produced by dipping in an emulsion containing a plasticizer. After soaking the emulsion is broken and the plasticizer absorbed, by heating.

On obtient, dans un tel procédé, un revêtement qui n'est pas totalement transparent du fait de la mise en émulsion préalable. De plus dans le cas d'un flacon en verre, l'aspect brillant de celui-ci est cassé et le revêtement procure un toucher légèrement collant, ou poisseux. A coating is obtained in such a process which is not completely transparent due to the prior emulsion. In addition in the case of a glass bottle, the shiny appearance of the latter is broken and the coating provides a slightly tacky or sticky feel.

On peut également revêtir des corps pleins par un procédé-dit de surmoulage mais un tel procédé n'est pas applicable à des corps creux ayant une paroi par exemple en verre. En effet les pressions exercées sur la face extérieure de la paroi sont très importantes et font éclater le corps creux. It is also possible to coat solid bodies by a process known as overmolding, but such a process is not applicable to hollow bodies having a wall, for example made of glass. Indeed, the pressures exerted on the outer face of the wall are very high and cause the hollow body to burst.

Pour remédier à ces inconvénienta la présente invention a pour but de fournir un procédé et une machine permettant de réaliser un flacon ayant une paroi relativement peu résistante et revêtue d'une couche continue de matière plastique gardant un aspect transparent et brillant et ayant un toucher agréable. To overcome these drawbacks, the object of the present invention is to provide a method and a machine making it possible to produce a bottle having a relatively weak wall and coated with a continuous layer of plastic material keeping a transparent and shiny appearance and having a pleasant touch. .

A cet effet l'invention a pour objet un procédé de revêtement d'un flacon par une pellicule en matière plastique caractérisé en ce qu'il consiste a:
a - positionner le flacon dans un moule d'injection d'une machine à inje#cter comportant un passage d'injection de la matière plastique et dont la paroi interne entoure la paroi externe du flacon à une distance de celle-ci correspondant sensiblement à l'épaisseur de la pellicule à réaliser,
b - injecter la matière plastique à travers le passage dans l'espace délimité par la paroi interne du moule et la paroi externe du flacon et mettre simultanément l'intérieur du flacon sous pression,
c - ouvrir le moule d'injection , et retirer le flacon revêtu du poste d'injection de la machine.To this end, the subject of the invention is a process for coating a bottle with a plastic film, characterized in that it consists of:
a - position the bottle in an injection mold of an injection machine # cter comprising an injection passage of the plastic material and the internal wall of which surrounds the external wall of the bottle at a distance from the latter corresponding substantially to the thickness of the film to be produced,
b - inject the plastic material through the passage in the space delimited by the internal wall of the mold and the external wall of the bottle and simultaneously put the inside of the bottle under pressure,
c - open the injection mold, and remove the coated bottle from the machine's injection station.

Selon d'autres caractéristiques
- la mise sous pression de l'intérieur du flacon consiste à insuffler un fluide sous pression à travers le col du flacon à partir d'un orifice du moule d'injection.According to other characteristics
- the pressurization of the interior of the bottle consists of blowing a pressurized fluid through the neck of the bottle from an orifice of the injection mold.

- la mise sous pression de l'intérieur du flacon consiste à insuffler un fluide sous pression à partir d'un conduit d'alimentation en fluide de la machine. - the pressurization of the interior of the bottle consists of blowing a pressurized fluid from a fluid supply duct of the machine.

- le fluide insufflé à partir du conduit d'alimentation en fluide de la machine est distribué à l'intérieur du flacon par un poinçon axial s'étendant à l'intérieur du flacon par le col de celui-ci. - The fluid blown from the fluid supply duct of the machine is distributed inside the bottle by an axial punch extending inside the bottle by the neck thereof.

L'invention concerne également
- une machine d'injection comportant un conduit d'alimentation en fluide sous pression relié à un canal de distribution réalisé à l'intérieur d'un poinçon axial s'étendant à l'intérieur du flacon par le col de celui-ci, le canal débou-chant à l'intérieur du flacon.The invention also relates to
an injection machine comprising a conduit for supplying pressurized fluid connected to a distribution channel produced inside an axial punch extending inside the bottle by the neck thereof, the outlet channel inside the bottle.

- la machine comporte des moyens de commande d'insufflation du fluide sous pression à l'intérieur du flacon. - The machine comprises means for controlling the insufflation of the pressurized fluid inside the bottle.

~ la machine comporte en outre des moyens de commande synchronisée de l'insufflation de fluide sous pression et de l'injection de matière plastique. ~ The machine further comprises means for synchronized control of the blowing of pressurized fluid and the injection of plastic material.

- la machine comporte des moyens d'étanchéité entre le poinçon et le flacon. - The machine includes sealing means between the punch and the bottle.

L'invention sera mieux comprise à la lecture de la description qui va suivre, en référence au dessin annexé aur lequel
- la figure 1 est une vue schématique d'un flacon entouré d'un moule d'injection d'une machine à injecter
Le procédé selon l'invention consiste tout d'abord à positionner un flacon 1 sur un poinçon 2 faisant partie d'un poste d'injection (non représenté) d'une machine à injecter. On met ensuite en place l'ensemble poinçon et flacon dans un moule en deux parties 4 comportant une cavité 5 dont la paroi interne 6 entoure la paroi externe du flacon à une distance de celle-ci correspondant à l'épaisseur de la pellicule que l'on désire réaliser. Le moule comporte également un passage d'injection 8 de la matière plastique qui débouche dans l'espace 7 délimité entre la paroi 6 de la cavité 5 et la paroi externe du flacon.Comme représenté à la figure 1, le poinçon 2 possède une forme allongée comportant 4 étages cylindriques coaxiaux.The invention will be better understood on reading the description which follows, with reference to the accompanying drawing in which
- Figure 1 is a schematic view of a bottle surrounded by an injection mold of an injection machine
The method according to the invention firstly consists in positioning a bottle 1 on a punch 2 forming part of an injection station (not shown) of an injection machine. The punch and bottle assembly is then put into place in a two-part mold 4 comprising a cavity 5, the internal wall 6 of which surrounds the external wall of the bottle at a distance from it corresponding to the thickness of the film that l 'we want to achieve. The mold also includes an injection passage 8 for the plastic material which opens into the space 7 delimited between the wall 6 of the cavity 5 and the external wall of the bottle. As shown in FIG. 1, the punch 2 has a shape elongated with 4 coaxial cylindrical stages.

Le premier étage 10 est destiné à permettre la fixation du poinçon sur le poste d'injection. Il est prolongé par un deuxième étage 12 d'un diamètre notablement plus grand. Le troisième étage 14 prolonge le deuxième étage 12 et possède un diamètre extérieur correspondant au diamètre extérieur du col 16 du flacon 1 a revêtir d'une pellicule de matière plastique, augmenté de l'épaisseur de la pellicule. Le diamètre du troisième étage 14 est plus petit que celui du deuxième étage 12 ce qui détermine un épaulement 18. The first stage 10 is intended to allow the fixing of the punch on the injection station. It is extended by a second stage 12 of a significantly larger diameter. The third stage 14 extends the second stage 12 and has an outside diameter corresponding to the outside diameter of the neck 16 of the bottle 1 to be coated with a plastic film, increased by the thickness of the film. The diameter of the third stage 14 is smaller than that of the second stage 12 which determines a shoulder 18.

Le quatrième étage 20, qui prolonge le troisième étage 14, possède un diamètre légèrement inférieur au diamètre intérieur du col 16 du flacon 1, ce qui détermine une surface annulaire radiale 22 entre le troisième étage 14 et le quatrième étage 20. The fourth stage 20, which extends the third stage 14, has a diameter slightly smaller than the inside diameter of the neck 16 of the bottle 1, which determines a radial annular surface 22 between the third stage 14 and the fourth stage 20.

La longueur du quatrième étage est telle qu'il s'étend à l'intérieur du flacon à travers le col sans que sa face extrême 24 ne soit en contact avec la paroi du flacon 1.The length of the fourth stage is such that it extends inside the bottle through the neck without its end face 24 being in contact with the wall of the bottle 1.

Le poinçon 2 est traversé axialement par un canal 26. Ce canal s'ouvre par un orifice d'entrée 28 à la face radiale libre du premier étage 10. Cet orifice d'entrée 28 est relié de manière habituelle à un circuit d'alimentation (non représenté) en fluide sous pression de la machine. Le canal 26 débouche à son autre extrémité par un orifice de sortie 30 à la face radiale d'extrêmité 24 du quatrième étage 20. The punch 2 is axially crossed by a channel 26. This channel opens through an inlet port 28 to the free radial face of the first stage 10. This inlet port 28 is connected in the usual way to a supply circuit. (not shown) in pressurized fluid of the machine. The channel 26 opens at its other end through an outlet orifice 30 to the radial end face 24 of the fourth stage 20.

A proximité de la surface annulaire radiale 22 le poinçon comporte des joints d'étanchéité 32, par exemple toriques,conçus pour assurer l'étanchéité entre le quatrième étage 20 et le col 16 du flacon 1. Near the radial annular surface 22 the punch has seals 32, for example O-rings, designed to seal between the fourth stage 20 and the neck 16 of the bottle 1.

Ces joints d'étanchéité 32 assurent également un serrage entre le quatrième étage 20 et le col 16 de façon à maintenir le flacon 1 en position autour du poinçon 2 et centré dans la cavité 5. L'extrémité ouverte du col 16 vient en butée sur la surface annulaire radiale 22. Dans cette position l'orifice de sortie 30 débouche à l'intérieur du flacon 1.These seals 32 also ensure a clamping between the fourth stage 20 and the neck 16 so as to keep the bottle 1 in position around the punch 2 and centered in the cavity 5. The open end of the neck 16 abuts on the radial annular surface 22. In this position, the outlet orifice 30 opens into the interior of the bottle 1.

Lorsque le flacon 1 a-été positionné autour du poinçon 2 comme indiqué ci-dessus, on entoure le flacon par le moule 4. Ce moule 4 est constitué de deux éléments semblables dont un seul a été représenté pour une plus grande clarté de la figure 1. L'élément de moule 31 comporte une collerette de fixation 34 et un corps 36 comportant la cavité 5. When the bottle 1 has been positioned around the punch 2 as indicated above, the bottle is surrounded by the mold 4. This mold 4 consists of two similar elements, only one of which has been shown for greater clarity in the figure. 1. The mold element 31 comprises a fixing flange 34 and a body 36 comprising the cavity 5.

La collerette 34 comporte un alésage 3#8 dans lequel est reçu le troisième étage 14 du poinçon 2. The flange 34 has a bore 3 # 8 in which the third stage 14 of the punch 2 is received.

L'alésage 38 est prolongé à l'intérieur du corps 36 de l'élément de moule 31 par la cavité 5 de moulage. La paroi 6 de la cavité de moulage possède la forme du flacon 1 à revêtir et en position est écartée de la surface extérieure du flacon 1, créant ainsi l'espace 7 entre le flacon 1 et la paroi 6 de la cavité de moulage. The bore 38 is extended inside the body 36 of the mold element 31 by the mold cavity 5. The wall 6 of the mold cavity has the shape of the bottle 1 to be coated and in position is spaced from the outer surface of the bottle 1, thus creating the space 7 between the bottle 1 and the wall 6 of the mold cavity.

Le deuxième élément du moule (non représenté) est alors positionné de manière semblable au premier élément 31, et on applique fermement de manière usuelle, les deux surfaces d'appuis de ces éléments l'une contre l'autre pour former le moule 4. The second element of the mold (not shown) is then positioned in a similar manner to the first element 31, and the two bearing surfaces of these elements are applied firmly in the usual manner against each other to form the mold 4.

on injecte de la matière plastique sous pression par le passage d'injection 8. La matière plastique emplit alors l'espace 7. plastic material is injected under pressure through the injection passage 8. The plastic material then fills the space 7.

Simultanément à l'injection, l'intérieur du flacon 1 est mis sous pression à l'aide du fluide sous pression insufflé à travers le canal 26 du poinçon 2. Simultaneously with the injection, the interior of the bottle 1 is pressurized using the pressurized fluid blown through the channel 26 of the punch 2.

Les dispositifs d'injection et d'insufflation sont pourvus d'une unité de régulation de type habituel (non représentée) de manière à obtenir des pressions pratiquement égales sur les deux faces de la paroi du flacon 1. The injection and insufflation devices are provided with a regulation unit of the usual type (not shown) so as to obtain almost equal pressures on the two faces of the wall of the bottle 1.

Lorsque la matière plastique injectée dans l'espace 7 a pris sa consistance définitive, on désolidarise les deux éléments du moule et on les écarte l'un de l'autre. When the plastic material injected into the space 7 has taken its final consistency, the two elements of the mold are separated and they are separated from one another.

Par une traction sur le flacon 1 allant à l'encontre de l'effet de retenue exercé par les joints d'étanchéité 32, on retire le flacon revêtu de matière plastique du poste d'injection. By pulling on the bottle 1 going against the retaining effect exerted by the seals 32, the plastic coated bottle is removed from the injection station.

Il apparait clairement que ce flacon revêtu d'une première pellicule peut, à son tour, être revêtu d'une autre pellicule par le procédé décrit ci-dessus, à l'aide d'un moule conçu de manière identique et possédant une cavité adaptée. It is clear that this bottle coated with a first film can, in turn, be coated with another film by the method described above, using a mold designed identically and having a suitable cavity. .

Dans une variante de la machine à injecter, on peut utiliser une alimentation en fluide sous pression indépendante de la machine. Dans ce cas le moule doit comporter dans la collerette 34, un conduit relié au canal 26 du poinçon et à l'alimentation du fluide sous pression.  In a variant of the injection machine, it is possible to use a pressurized fluid supply independent of the machine. In this case the mold must include in the collar 34, a conduit connected to the channel 26 of the punch and to the supply of the pressurized fluid.
