Abstract

The bottom panel for an injection moulded plastic bottle has spaced radial grooves (9) opening into the sidewall of a centra dimple. The bottom is bi-directional and has an optimum grain direction. The grooves extend radially from the moulding injection point.

Description

La présente invention concerne un perfectionnement apporté aux bouteilles en plastique ainsi qu'au procédé et à l'outillage utilisés pour leur fabrication.The present invention relates to an improvement made to plastic bottles and the process and tools used to make them manufacturing.

De telles bouteilles sont obtenues par soufflage de préformes, elles-mêmes obtenues par injection moulage.Such bottles are obtained by blowing preforms, themselves obtained by injection molding.

Le fond d'une bouteille présente une face d'appui, plus ou moins concave, comportant éventuellement une pluralité de nervures de raidissement disposées radialement en direction d'une légère dépression centrale où est situé le point d'injection.The bottom of a bottle has a support face, more or less concave, possibly including a plurality of stiffening ribs arranged radially towards a slight central depression where is located the injection point.

Cette dépression de forme sensiblement bombée ou hémisphérique constitue une zone de fragilité autour de laquelle se situe une zone annulaire de matière amorphe. Les nervures ne peuvent, par conséquent, déboucher dans cette dépression centrale.This depression of substantially convex or hemispherical shape constitutes a zone of weakness around which an annular zone of amorphous matter. The ribs cannot therefore open into this central depression.

Dans le but de réaliser un gain de poids sur la bouteille, la demanderesse a cherché à diminuer la partie amorphe du fond de la bouteille, ce que l'on ne savait réaliser jusqu'à présent sans entraíner une diminution de la résistance à la chute et une diminution de la résistance à la compression verticale.In order to achieve weight gain on the bottle, the plaintiff has sought to reduce the amorphous part of the bottom of the bottle, what we could not achieve until now without causing a decrease in resistance to falling and a decrease in compressive strength vertical.

La demanderesse a non seulement réussi à résoudre ce problème sans diminution de résistance, mais elle est allée au-delà car elle propose une solution permettant de diminuer la partie amorphe tout en augmentant la résistance.The plaintiff has not only succeeded in solving this problem without resistance decrease, but it went further because it offers a solution to reduce the amorphous part while increasing the resistance.

Pour cela elle est allée à l'encontre des idées reçues.For that it went against the received ideas.

Une première idée reçue consiste à penser qu'il est impossible de supprimer cette partie amorphe sans nuire à la solidité de la bouteille.A first received idea is to think that it is impossible to remove this amorphous part without affecting the solidity of the bottle.

Une deuxième idée reçue consiste à penser que des nervures dont le profil présenterait des angles vifs seraient inévitablement cause de fragilité.A second received idea consists in thinking that ribs whose profile would have sharp angles would inevitably cause fragility.

L'invention consiste en une bouteille en plastique obtenue par soufflage d'une préforme, elle-même obtenue préalablement par injection moulage, et composée principalement d'un corps tubulaire, par exemple cylindrique, réuni au fond de la bouteille, ledit fond comportant une assise plane et éventuellement des nervures de raidissement disposées en étoile en direction du point d'injection situé dans une dépression centrale du fond de la bouteille, caractérisé en ce que ledit fond est bi-étiré dans sa totalité et présente un cristallisation induite optimale.The invention consists of a plastic bottle obtained by blowing a preform, itself obtained beforehand by injection molding, and mainly composed of a tubular body, for example cylindrical, joined at the bottom of the bottle, said bottom comprising a flat seat and possibly stiffening ribs arranged in a star direction from the injection point located in a central depression at the bottom of the bottle, characterized in that said bottom is bi-stretched in its entirety and has a optimal induced crystallization.

De préférence, le fond de la bouteille selon l'invention présente en tout point une épaisseur inférieure à 1 mm.Preferably, the bottom of the bottle according to the invention has in all point a thickness less than 1 mm.

En outre les nervures de raidissement débouchent dans la dépression centrale et présentent au moins une arête vive.In addition, the stiffening ribs open into the depression. central and have at least one sharp edge.

On comprendra mieux l'invention à l'aide de la description qui suit d'un modèle de bouteille à fond circulaire, non limitatif de l'invention, faite en référence aux figures annexées suivantes :

  • La figure 1 montre, en vue de dessous, un fond conforme à l'invention pour bouteille ronde standard,
  • La figure 2 montre, vu en coupe selon A-A, le fond de la figure 1,
  • La figure 3 montre une section selon B-B de la figure 2.
The invention will be better understood with the aid of the following description of a bottle model with a circular bottom, without limitation of the invention, made with reference to the following appended figures:
  • FIG. 1 shows a bottom view in accordance with the invention for a standard round bottle,
  • FIG. 2 shows, seen in section along AA, the bottom of FIG. 1,
  • FIG. 3 shows a section along BB of FIG. 2.

Le fond (1) représenté en figure 1 comporte une face d'appui (2) avec un plan d'assise circulaire (4), des nervures principales (7) de raidissement, par exemple cinq, disposées radialement en direction du centre des nervures supplémentaires plus courtes (9), et une dépression centrale, comportant le point d'injection (5).The bottom (1) shown in Figure 1 has a bearing face (2) with a circular seating plane (4), main stiffening ribs (7), by example five, arranged radially towards the center of the ribs additional shorter (9), and a central depression, comprising the injection point (5).

Conformément à l'invention, la dépression centrale présente la forme d'un cratère (6) avec une paroi latérale en forme sensiblement de tronc de cône, d'angle au sommet compris entre 20° et 45°, une zone supérieure centrale (3) sensiblement circulaire dans laquelle se trouve le point d'injection, et une gorge annulaire entourant ladite zone centrale.According to the invention, the central depression has the form a crater (6) with a side wall substantially in the form of a trunk cone, angle at the top between 20 ° and 45 °, an upper zone substantially circular central unit (3) in which the injection point is located, and an annular groove surrounding said central area.

En outre, au moins une partie des nervures, ici les nervures principales (7), ont une extrémité débouchant dans la paroi latérale du cratère, l'autre extrémité débouchant dans l'arrondi périphérique (8) du fond (1).In addition, at least part of the ribs, here the main ribs (7), have one end opening into the side wall of the crater, the other end opening into the peripheral rounding (8) of the bottom (1).

Des nervures supplémentaires (9) plus courtes, sont prévues de façon connue en soi, entre les nervures principales.Additional ribs (9) shorter, are provided so known per se, between the main ribs.

De préférence l'angle au sommet du cratère vaut sensiblement 40°. Preferably the angle at the top of the crater is substantially 40 °.

En éloignant ainsi le point d'injection par rapport au fond de la bouteille, on a pu étirer totalement le fond, supprimer la zone amorphe, diminuer l'épaisseur du fond qui ne dépasse en aucun point 1 mm, alléger la bouteille par gain de matière et réaliser des nervures débouchantes pour augmenter les propriétés mécaniques de la bouteille.By moving the injection point away from the bottom of the bottle, we were able to fully stretch the background, remove the amorphous area, decrease the thickness of the bottom which does not exceed at any point 1 mm, lighten the bottle by saving material and making through ribs to increase the mechanical properties of the bottle.

La zone supérieure centrale sera la plus petite possible et de préférence de diamètre égal à celui de la canne de soufflage.The central upper zone will be as small as possible and preferably diameter equal to that of the blowing rod.

Les nervures (7,9) présentent un profil triangulaire avec une arête vive au sommet dont l'angle est compris entre 50° et 75°, de préférence 70° (voir figure 3).The ribs (7, 9) have a triangular profile with a sharp edge at the top whose angle is between 50 ° and 75 °, preferably 70 ° (see figure 3).

D'autres profils d'arêtes seraient possibles.Other edge profiles would be possible.

L'invention s'applique quelle que soit la forme du fond et/ou la contenance de la bouteille.The invention applies regardless of the shape of the bottom and / or the capacity of the bottle.

Pour l'exemple d'une bouteille de 1 litre représentée sur les figures, le poids du fond est de 3,4 g avec une résistance à la compression verticale de 69 daN, contre 5 g pour 50 daN dans l'art antérieur.For the example of a 1 liter bottle shown in the figures, the bottom weight is 3.4 g with a vertical compressive strength of 69 daN, against 5 g for 50 daN in the prior art.

Les résultats obtenus sont rendus possibles par un taux d'étirage important de la matière lors de l'étape de soufflage de la préforme, de façon à permettre des temps de cycles très courts (plus de 1500 bouteilles/h). Le taux d'étirage surfacique doit être supérieur ou égal à 12 et de préférence voisin de 15.The results obtained are made possible by a stretch rate important material during the preform blowing step, so that allow very short cycle times (over 1500 bottles / h). The rate surface stretching must be greater than or equal to 12 and preferably close to 15.

Par ailleurs, on utilise un outillage approprié, à savoir un outillage dont le fond comporte une forme complémentaire de celle du fond de la bouteille à façonner, et possédant par conséquent des nervures en saillie, avec des arêtes vives, ce qui est entièrement à l'encontre des habitudes du métier. Le fond de l'outillage devra également être réalisé en matériau très bon conducteur de la chaleur pour l'efficacité du refroidissement.Furthermore, an appropriate tool is used, namely a tool whose bottom has a shape complementary to that of the bottom of the bottle shaping, and therefore having projecting ribs, with edges lively, which is entirely against the customs of the trade. The bottom of the tools must also be made of a material which is a very good conductor of the heat for cooling efficiency.
