Description

La présente invention concerne les récipients tubulaires réalisés par des tubes en matière plastique ou analogue.The present invention relates to tubular containers made of plastic or similar tubes.

Les récipients connus sont souvent fabriqués à partir d'un tube extrudé en continu qui est ensuite coupé à longueur et auquel on adapte d'un côté une tête formant un épaulement ainsi qu'une bague à vis ou un goulot sur lequel est ensuite mis en place un bouchon de fermeture.Known containers are often made from a continuous extruded tube which is then cut to length and to which is adapted on one side a head forming a shoulder as well as a screw ring or a neck on which is then placed places a closure cap.

Le récipient ainsi constitué présente un fond ouvert pour permettre son remplissage et le fond est finalement fermé en le soudant ou en le sertissant par un moyen quelconque connu de la technique et adapté à la matière constitutive dudit récipient.The container thus formed has an open bottom to allow its filling and the bottom is finally closed by welding or crimping by any means known in the art and suitable for the material of said container.

Dans d'autres réalisations, la tête et le corps du flacon sont réalisés en une seule pièce par injection dans un moule et le récipient est comme précédemment rempli avant fermeture de son fond.In other embodiments, the head and the body of the bottle are made in one piece by injection into a mold and the container is as previously filled before closing its bottom.

Pour certaines applications, notamment pour certains traitements à partir de produits cosmétiques et aussi pour d'autres produits, par exemple pour des colles ou des peintures à deux constituants, il est nécessaire de prévoir deux récipients et un emballage particulier pour recevoir ces deux récipients afin que les produits de nature différente qu'ils contiennent ne puissent en aucun cas être mis en contact avant leur utilisation.For certain applications, in particular for certain treatments from cosmetic products and also for other products, for example for glues or paints with two components, it is necessary to provide two containers and a special packaging to receive these two containers in order that the products of a different nature which they contain cannot in any case be brought into contact before their use.

La présente invention crée un nouveau récipient tubulaire rendant possible de contenir au moins deux produits sans que ceux-ci puissent être mélangés avant leur emploi et cela sans compliquer la fabrication du récipient réalisé en une pièce par un procédé d'injection.The present invention creates a new tubular container making it possible to contain at least two products without these being able to be mixed before their use and this without complicating the manufacture of the container produced in one piece by an injection process.

Conformément à l'invention, le récipient tubulaire déformable est caractérisé en ce qu'il comporte au moins une cloison longitudinale délimitant des compartiments distincts à l'intérieur d'un corps tubulaire, au moins la partie de la cloison se trouvant au niveau du fond du corps du récipient présentant une largeur égale au demi-périmètre interne dudit corps et ladite cloison étant reliée rigidement et de façon étanche à la paroi dudit corps par des segments.According to the invention, the deformable tubular container is characterized in that it comprises at least one longitudinal partition delimiting separate compartments inside a tubular body, at least the part of the partition being at the bottom of the container body having a width equal to the internal half-perimeter of said body and said partition being rigidly and sealingly connected to the wall of said body by segments.

L'invention s'étend aussi au procédé pour la fabrication du récipient.The invention also extends to the method for manufacturing the container.

Conformément à cette seconde disposition de l'invention, le procédé pour la fabrication en une pièce d'un réci­pient comportant au moins une cloison longitudinale interne pour délimiter des compartiments communiquant avec l'extérieur par des ouvertures, ledit récipient étant réalisé par injection d'une matière plastique dans un moule, est caractérisé en ce qu'on prévoit un noyau mobile par rapport au moule, ledit noyau présentant au moins une fente longitudinale pour la formation de la cloison et des moyens de liaison pour relier ses parties fendues au moule en empêchant leur déformation.According to this second arrangement of the invention, the method for manufacturing in one piece a container comprising at least one internal longitudinal partition for delimiting compartments communicating with the outside by openings, said container being produced by injection of a plastic material in a mold, is characterized in that a movable core is provided relative to the mold, said core having at least one longitudinal slot for the formation of the partition and connecting means for connecting its split parts to the mold in preventing their deformation.

Diverses autres caractéristiques de l'invention ressor­tent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, au dessin annexé.

  • La fig.1 est une vue de dessus du récipient tubulaire déformable, objet de l'invention.
  • La fig.2 est une coupe prise suivant la ligne II-II de la fig.1, le récipient étant muni d'un bouchon de fermeture.
  • La fig.3 est une coupe prise suivant la ligne III-III de la fig.2.
  • La fig.4 est une coupe prise suivant la ligne IV-IV de la fig.2.
An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing.
  • Fig.1 is a top view of the deformable tubular container, object of the invention.
  • Fig.2 is a section taken on the line II-II of Fig.1, the container being provided with a closure cap.
  • Fig.3 is a section taken along line III-III of Fig.2.
  • Fig.4 is a section taken on line IV-IV of Fig.2.

Le récipient illustré au dessin comporte un corps tubu­laire 1 représenté de section circulaire mais qui peut, le cas échéant, présenter une autre forme, par exemple ovale.The container illustrated in the drawing comprises a tubular body 1 shown of circular section but which may, if necessary, have another shape, for example oval.

A sa partie supérieure, le corps 1 forme un épaulement 2 et un goulot 3 destiné à recevoir un bouchon de fermeture 4. Les moyens de liaison entre le goulot 3 et le bouchon de fermeture 4 peuvent être quelconques.At its upper part, the body 1 forms a shoulder 2 and a neck 3 intended to receive a closure plug 4. The connecting means between the neck 3 and the closure plug 4 may be any.

Dans l'exemple représenté, le goulot 3 est fileté et le bouchon de fermeture 4 comporte intérieurement une jupe taraudée 5 vissée sur le goulot.In the example shown, the neck 3 is threaded and the closure plug 4 has internally a threaded skirt 5 screwed onto the neck.

Le bouchon de fermeture pourrait être maintenu de façon analogue par un jonc ou des protubérances ou tous autres moyens connus dans la technique du bouchage des réci­pients .The closure plug could be maintained in a similar manner by a rod or protrusions or any other means known in the art of plugging containers.

Intérieurement, le corps 1 est muni d'une cloison 6 qui est ondulée ou autrement conformée pour que sa longueur développée soit égale au demi-périmètre interne du corps 1 lorsque celui-ci est au repos.Internally, the body 1 is provided with a partition 6 which is corrugated or otherwise shaped so that its developed length is equal to the internal half-perimeter of the body 1 when the latter is at rest.

Il est avantageux, ainsi que l'illustre particulièrement la fig.3, que la cloison 6 soit reliée à l'intérieur du corps 1 par deux segments rectilignes 7 et 8 pour facili­ter ensuite la déformation des ondulations 9 lorsque le corps tubulaire doit être fermé à sa partie inférieure.It is advantageous, as illustrated in particular in fig.3, that the partition 6 is connected to the interior of the body 1 by two straight segments 7 and 8 to then facilitate the deformation of the corrugations 9 when the tubular body must be closed at its bottom.

La cloison 6 est réalisée de manière à s'étendre jusqu'au sommet du goulot 3 qui est fermé par un plateau 10 dans lequel sont prévues des ouvertures 11 et 12 ouvrant de part et d'autre de la cloison 6 dans des compartiments 13 et 14 que celle-ci délimite à l'intérieur du corps 1.The partition 6 is made so as to extend to the top of the neck 3 which is closed by a plate 10 in which are provided openings 11 and 12 opening on either side of the partition 6 in compartments 13 and 14 that it delimits inside the body 1.

L'ensemble corps 1 et cloison 6 est fabriqué de préfé­rence en résine thermoplastique par injection et on prend soin de conformer le moule pour que la cloison 6 ne présente pas d'angle vif mais délimite au contraire une suite d'éléments arrondis y compris dans sa zone joignant les segments rectilignes.The body 1 and partition 6 assembly is preferably made of thermoplastic resin by injection and care is taken to shape the mold so that the partition 6 does not have a sharp angle but instead delimits a series of rounded elements including in its area joining the straight segments.

Les compartiments 13 et 14 sont remplis des produits qu'ils doivent contenir avant que le fond 15 du corps tubulaire 1 soit fermé.The compartments 13 and 14 are filled with the products which they must contain before the bottom 15 of the tubular body 1 is closed.

La fermeture du fond 15 est réalisée par les moyens habituels de la technique, c'est-à-dire que ce fond est serré et chauffé pour assurer une fermeture étanche, le fond devient alors linéaire comme illustré en traits mixtes à la fig.2 et selon la coupe apparaissant à la fig.4. La fermeture peut aussi être assurée par sertis­sage du fond 15.The bottom 15 is closed by the usual means of the technique, that is to say that this bottom is tightened and heated to ensure a tight closure, the bottom then becomes linear as illustrated in dashed lines in FIG. 2 and according to the section appearing in fig. 4. The closure can also be ensured by crimping the bottom 15.

Etant donné que la longueur développée de la cloison 6 est égale au demi-périmètre du corps 1, l'opération de fermeture par serrage et chauffage ou sertissage du fond 15 fait que la cloison est aplatie et prise en sandwich entre les deux parties correspondantes du corps 1 qui sont elles-mêmes aplaties comme illustré par la fig.4.Since the developed length of the partition 6 is equal to the half-perimeter of the body 1, the closing operation by clamping and heating or crimping the bottom 15 causes the partition to be flattened and sandwiched between the two corresponding parts of the body 1 which are themselves flattened as illustrated in fig.4.

Il est avantageux que les ouvertures 11 et 12 soient fermées par des protubérances ou autres moyens spécifi­ques prévus dans le bouchon de fermeture, ces moyens étant de préférence conçus pour qu'ils correspondent toujours l'un à l'ouverture 11, l'autre à l'ouverture 12.It is advantageous that the openings 11 and 12 are closed by protrusions or other specific means provided in the closure cap, these means being preferably designed so that they always correspond one to the opening 11, the other to opening 12.

Il est ainsi possible de remplir les compartiments 13 et 14 de produits ne devant pas être mélangés ou amenés en contact avant usage, comme cela peut être le cas d'une résine et de son durcisseur ou encore comme cela peut être le cas de produits de traitement tels que des produits cosmétiques dont le mélange ne doit être assuré qu'au moment de l'utilisation.It is thus possible to fill the compartments 13 and 14 with products which should not be mixed or brought into contact before use, as may be the case with a resin and its hardener or even as this may be the case with treatment such as cosmetic products, the mixing of which must only be ensured at the time of use.

Le récipient décrit dans ce qui précède se prête particu­lièrement à une fabrication par moulage par injection d'une matière plastique. Cependant, pour mettre ce procédé en oeuvre, le moule doit être prévu pour coopérer avec un noyau fendu sur toute sa hauteur pour permettre la formation de la cloison 6. Il est important à cette fin que le moule soit muni de moyens de blocage des extrémités du noyau pour éviter sa déformation au moment de l'injection. Les moyens de blocage sont avantageuse­ment constitués par des tétons assurant la formation des ouvertures 11, 12 et s'engageant dans des lumières de blocage prévues dans le fond du moule. Pour faciliter le démoulage, la fente du noyau présente une épaisseur progressivement croissante vers les moyens de blocage.The container described in the foregoing is particularly suitable for manufacture by injection molding of a plastic material. However, to implement this method, the mold must be provided to cooperate with a split core over its entire height to allow the formation of the partition 6. It is important for this purpose that the mold is provided with means for blocking the ends. of the nucleus to avoid its deformation at the time of injection. The blocking means advantageously consist of pins ensuring the formation of the openings 11, 12 and engaging in blocking slots provided in the bottom of the mold. To facilitate demolding, the core slot has a progressively increasing thickness towards the locking means.

L'invention n'est pas limitée à l'exemple de réalisation représenté et décrit en détail car diverses modifications peuvent y être apportées sans sortir de son cadre. En particulier, la cloison peut n'être ondulée que sur une partie de sa longueur. De même, l'amplitude des ondula­tions peut décroître depuis le fond 15 jusqu'au goulot.The invention is not limited to the embodiment shown and described in detail since various modifications can be made without departing from its scope. In particular, the partition may only be corrugated over part of its length. Likewise, the amplitude of the undulations can decrease from the bottom 15 to the neck.
