Procédé de fabrication d'une bouteille en matiere plastique
et bouteille obtenue par ce procédé"
L'invention concerne un procédé de fabrication d'vine bouteille en matière plastique, ainsi que la bouteille obtenue par ce procédé.Method of manufacturing a plastic bottle
and bottle obtained by this process "
The invention relates to a method for manufacturing a plastic bottle, as well as the bottle obtained by this method.
Dans un procédé classique de fabrication d'une bouteille en matière plastique, tel que celle représentée sur la figure 1, lorsque la partie de goulot 3 et la partie d'épaulement 4 qui lui fait suite, sont formés d'une seule pièce avec le corps 2 de la bouteille 1 se logeant dans le moule a injection (non représenté), l'embout de coulée 6 destiné à injecter la résine plastique est monté sur une embouchure verseuse 5 placée à l'extrémité supérieure de la partie de goulot 3, cette résine plastique étant injectée par l'embout de coulée 6 pour former la partie de goulot 3 et la partie d'épaulement 4 de la bouteille 1 en coulant ainsi d'une seule piece l'extrémité inférieure de la partie d'épaulement 4 et l'extrémité supérieure du corps 2 de la bouteille. In a conventional method of manufacturing a plastic bottle, such as that shown in FIG. 1, when the neck portion 3 and the shoulder portion 4 which follows it, are formed in one piece with the body 2 of the bottle 1 being housed in the injection mold (not shown), the pouring nozzle 6 intended for injecting the plastic resin is mounted on a pouring mouthpiece 5 placed at the upper end of the neck portion 3, this plastic resin being injected by the pouring nozzle 6 to form the neck portion 3 and the shoulder portion 4 of the bottle 1, thereby pouring in one piece the lower end of the shoulder portion 4 and the upper end of the body 2 of the bottle.
La bouteille de matière plastique est finalement réalisée par ce procédé en coupant une partie repérée par la ligne de coupe 7 à la partie inférieure de la coulée de résine remplissant l'embout 6. Cependant, le procédé classique décrit ci-dessus, bien qu'il permette de former facilement la partie de goulot 3 et autres, du fait de la grande fluidité de la résine d'injection, conduit cependant à réaliser cette opération en ouvrant l'embouchure verseuse 5 par une coupe de l'embout 6 faisant suite à cette embouchure 5 finalement placé à ltextrémité supérieure comme décrit ci-dessus. The plastic bottle is finally produced by this process by cutting a part marked by the cutting line 7 at the bottom of the resin flow filling the nozzle 6. However, the conventional process described above, although it allows the neck portion 3 and the like to be easily formed, due to the great fluidity of the injection resin, however, leads to this operation by opening the pouring mouthpiece 5 by cutting the mouthpiece 6 following this mouth 5 finally placed at the upper end as described above.
Il en résulte que le procédé classique présente les inconvénients suivants (A) L'opération de coupe prend beaucoup de temps. As a result, the conventional method has the following drawbacks (A) The cutting operation takes a long time.
(B) La surface de coupe risque d'être inclinée.(B) The cutting surface may be tilted.
(C) Une dispersion se produit dans les tailles supérieure et inférieure.(C) Dispersion occurs in the upper and lower sizes.
(D) Comme la surface de coupe n'est pas lisse mais présente au contraire des bords coupants, on risque de se blesser la figure sicelle-ci Rient directement en contact avec les bords coupants de la partie versante de la bouteille.(D) As the cutting surface is not smooth but has sharp edges on the contrary, there is a risk of injury to the figure if it falls directly in contact with the sharp edges of the pouring part of the bottle.
(E) Il est difficile de maintenir l'étanchéité en inclinant le capuchon du fait que la surface de coupe risque d'être inclinée ou de ne pas être lisse.(E) It is difficult to maintain the seal by tilting the cap because the cutting surface may be tilted or not be smooth.
(F) Le contenu de la bouteille une fois vidée peut rester partiellement accroché aux saillies de la partie supérieure entourant la partie de coupe.(F) The contents of the bottle once emptied may remain partially attached to the projections of the upper part surrounding the cutting part.
L'invention a pour but de pallier ces inconvénients de l'art antérieur en créant une technique nouvelle permettant d'obtenir une surface horizontale et lisse ou une surface de courbure déterminée, autour de l'embouchure verseuse de la bouteille, sans qu'il soit nécessaire d'effectuer l'opération de coupe décrite ci-dessus. The object of the invention is to overcome these drawbacks of the prior art by creating a new technique making it possible to obtain a horizontal and smooth surface or a determined surface of curvature, around the pouring mouth of the bottle, without it it is necessary to carry out the cutting operation described above.
A cet effet, l'invention concerne un procédé de fabrication d'une bouteille en matière plastique, dans lequel un corps de bouteille cylindrique précédemment fabriqué est introduit dans un moule à injection comprenant une cavité, des noyaux, une forme fendue et autres, puis dans lequel on forme d'une seule pièce avec ce corps, la partie de goulot et la partie d'épaulement faisant suite à celle-ci, procédé caractérisé en ce qu'il comprend les différentes étapes consistant à disposer un embout d'injection de résine plastique et un trou de coulée faisant suite à cet embout, sur le coté de la circonférence extérieure de la partie de goulot de la bouteille ; à prévoir une contraction de surface fixe à un endroit déterminé de la partie de goulot ou de la partie d'épaulement lui faisant suite ; et à effectuer ainsi un moulage d'une seule pièce du goulot de la bouteille et de la partie d'épaulement lui faisant suite. To this end, the invention relates to a method of manufacturing a plastic bottle, in which a previously manufactured cylindrical bottle body is introduced into an injection mold comprising a cavity, cores, a split shape and the like, then in which there is formed in one piece with this body, the neck portion and the shoulder portion following it, a process characterized in that it comprises the various stages consisting in placing a nozzle for injecting plastic resin and a tap hole following this tip, on the side of the outer circumference of the neck portion of the bottle; providing a fixed surface contraction at a determined location in the neck portion or the shoulder portion which follows it; and thus to carry out a single-piece molding of the neck of the bottle and of the shoulder part which follows it.

On décrira maintenant les différentes formes de réalisation de l'invention en se référant aux dessins. The various embodiments of the invention will now be described with reference to the drawings.
Sur la figure 2, un moule à injection permettant de mettre en oeuvre le procédé selon l'invention, comprend un premier noyau 9, une forme fendue 10, une cavité 11, un second noyau 12, et une turbine d'éjection 13. In FIG. 2, an injection mold allowing the method according to the invention to be implemented, comprises a first core 9, a split form 10, a cavity 11, a second core 12, and an ejection turbine 13.
L'embout de coulée 6 permettant d'obtenir le moulage par injection à l'endroit de la partie de goulot 3 et de la partie d'épaulement 4 de la bouteille 1, et le trou de coulée 14 situé à l'extrémité supérieure de l'embout de coulée 6, sont respectivement prévus dans des parties de la cavité 11 et de la forme fendue 10, et débouchent à un endroit correspondant à un anneau d'appui 15 formé sur la circonférence extérieure inférieure de la partie de goulot 3 du moule métallique 8. De plus, la contraction de surface de l'embouchure large 16, permettant d'étrangler le débit de la résine injectée, est prévue à l'endroit de la circonférence intérieure inférieure de la partie de goulot 3. The pouring nozzle 6 making it possible to obtain injection molding at the location of the neck part 3 and the shoulder part 4 of the bottle 1, and the tap hole 14 located at the upper end of the pouring tip 6, are respectively provided in parts of the cavity 11 and of the slit shape 10, and open at a place corresponding to a support ring 15 formed on the lower outer circumference of the neck part 3 of the metal mold 8. In addition, the surface contraction of the wide mouth 16, making it possible to throttle the flow rate of the injected resin, is provided at the location of the lower internal circumference of the neck portion 3.
Bien que, dans l'exemple ci-dessus, le trou de coulée 14 soit prévu à un endroit correspondant à l'anneau d'appui 15 de la partie de goulot 3, ce trou de coulée peut être prévu à l'endroit de la circonférence extérieure du fond de filetage de la partie de goulot 3, comme indiqué en pointillés. De plus, la contraction de surface de l'embouchure large 16 peut être prévue non seulement à l'endroit de la partie inférieure du goulot 3, mais encore à l'endroit de la circonférence intérieure de la partie d'épaulement 4, comme indiqué sur la figure 3, ou encore à l'endroit de la circonférence extérieure de la partie de base de l'épaulement 4, comme indiqué sur la figure 4. En outre, dans les exemples ci-dessus, l'extrémité supérieure de la partie de goulot 3 est prévue horizontale et lisse, le bord d'angle 17 de sa cironférence extérieure étant préalablement légèrement courbé. Although, in the example above, the tap hole 14 is provided at a location corresponding to the support ring 15 of the neck portion 3, this tap hole can be provided at the location of the outer circumference of the thread bottom of the neck portion 3, as shown in dotted lines. In addition, the surface contraction of the wide mouth 16 can be provided not only at the location of the lower part of the neck 3, but also at the location of the inner circumference of the shoulder portion 4, as indicated. in FIG. 3, or also at the location of the outer circumference of the base part of the shoulder 4, as shown in FIG. 4. Furthermore, in the examples above, the upper end of the part neck 3 is provided horizontal and smooth, the corner edge 17 of its outer circumference being previously slightly curved.
Cependant, on peut donner à l'ensemble de l'extrémité supérieure de la partie de goulot 3 la forme d'une surface librement courbée, cette surface étant convexe, concave ou autre. However, the assembly of the upper end of the neck portion 3 can be given the shape of a freely curved surface, this surface being convex, concave or other.
Dans la mise en oeuvre du procédé selon l'invention la résine injectée par l'embout de coulée 6 et le trou de coulée 14, remplit tout d'abord circulairement l'extrémité supérieure de l'anneau d'appui 15 et de la partie de goulot 3, autour du trou de coulée 14, gracie à la contraction de surface de l'embouchure large 16, puis descend circulairement en passant par cette contraction de surface de l'embouchure large 16 et en s'étalant radialement sur l'épaulement 4. In the implementation of the method according to the invention the resin injected by the pouring nozzle 6 and the tap hole 14, first of all circularly fills the upper end of the support ring 15 and of the part neck 3, around the taphole 14, thanks to the surface contraction of the wide mouth 16, then descends circularly by passing through this surface contraction of the wide mouth 16 and spreading radially over the shoulder 4.
Ainsi la résine fondue est coulée de telle manière que l'extrémité supérieure du corps de bouteille 2 soit préalablement introduite dans l'extrémité supérieure de la partie d'épaulement 4, ce qui lui permet de former la bouteille 1.Thus, the molten resin is poured in such a way that the upper end of the bottle body 2 is previously introduced into the upper end of the shoulder part 4, which allows it to form the bottle 1.
Le procédé selon l'invention permet d'obtenir les caractéristiques suivantes. The method according to the invention makes it possible to obtain the following characteristics.
(1) Il n'est pas nécessaire d'effectuer une opération de coupe de la résine pour séparer l'embout de coulée relié à la partie supérieure de l'embouchure, comme c'était le cas dans le procédé selon l'art antérieur; (2) Par suite on ne risque plus d'avoir une inclinaison de la surface de coupe ou une dispersion entre les tailles supérieure et inférieure (3) La surface d'extrémité supérieure entourant l'embouchure verseuse de la partie de goulot peut toujours être horizontale et lisse (4) On peut donner à la surface d'extrémité supérieure une forme arbitraire telle qu'une forme convexe, concave ou autre (5) La surface d'angle de la circonférence extérieure de la surface d'extrémité supérieure peut être arrondie par incurvation (6) Etant donné qu'il n'y a pas de discontinuité dans la surface d'extrémité supérieure, comme dans le procédé selon l'art antérieur, on ne risque pas de retenir à cet endroit du produit contenu dans la bouteille (7) La trace du trou de coulée est petite et invisible du fait que ce trou de coulée correspondant à la circonférence extérieure de la partie de goulot, se trouve automatiquement coupée lorsque la partie de goulot est séparée du moule métallique (8) Comme la surface d'extrémité supérieure de la partie de goulot est horizontale et peut être#réalisée sous la forme d'une surface lisse ou courbe sans opération de finition, et comme la précision de moulage est excellente, l'embouchure verseuse peut être fermée de manière étanche par un capuchon; ; (9) Comme on prévoit la contraction de surface de l'embouchure large à l'endroit de la partie de goulot ou d'une partie de l'épaulement, on peut contrôler la vitesse et la pression de la résine coulant vers la partie déposée de l'épaulement et du corps de bouteille, ce qui permet d'éviter la formation de barbes ou autres dues à un surplus de remplissage. (1) It is not necessary to perform a resin cutting operation to separate the pouring nozzle connected to the upper part of the mouthpiece, as was the case in the method according to the prior art ; (2) As a result there is no longer any risk of having an inclination of the cutting surface or a dispersion between the upper and lower sizes (3) The upper end surface surrounding the pouring mouth of the neck portion can always be horizontal and smooth (4) The upper end surface can be given an arbitrary shape such as a convex, concave or other shape (5) The corner surface of the outer circumference of the upper end surface can be rounded by curving (6) Since there is no discontinuity in the upper end surface, as in the method according to the prior art, there is no risk of retaining at this location the product contained in the bottle (7) The trace of the tap hole is small and invisible due to the fact that this tap hole corresponding to the outside circumference of the neck part, is automatically cut when the neck part is separated from the metal mold (8) As the surface of the upper end of the neck portion is horizontal and can be # made in the form of a smooth or curved surface without finishing operation, and as the molding precision is excellent, the pouring mouthpiece can be sealed by a cap; ; (9) Since the surface of the wide mouth is contracted at the location of the neck portion or part of the shoulder, the speed and pressure of the resin flowing towards the deposited portion can be controlled of the shoulder and of the bottle body, which makes it possible to avoid the formation of barbs or the like due to an excess of filling.
