Abstract

1. A bottle made of polyvinyl chloride or of a plastic material with a comparable rigidity, comprising a body whose lateral wall is capable of being compressed in turns to produce small jets of liquids, characterised in that the said body has on its side wall, at least one fold extending substantially parallel to the axis of the bottle without leading either into the wall of the bottom of the bottle or into the upper side of the body of the bottle, the said fold (8) forming a reinforcement and the remaining zone (9) of the lateral wall forming a relatively soft portion which may be deformed manually.

Description

On sait qu'un très grand nombre de flacons ou de récipients de faible contenance sont pourvus d'une paroi souple que l'on comprime alternativement pour produire à travers un orifice de petite dimension un mince jet de liquide pouvant être aisément réparti et interrompu. C'est le cas, par exemple, de flacons destinés à contenir une dose de lotion capillaire devant être, au moment de l'application, distribuée de façon égale sur l'ensemble de la chevelure.It is known that a very large number of bottles or containers of small capacity are provided with a flexible wall which is compressed alternately to produce through a small orifice a thin jet of liquid which can be easily distributed and interrupted. This is the case, for example, of bottles intended to contain a dose of hair lotion which must be, at the time of application, distributed equally over the whole of the hair.

Les flacons de ce genre sont commodément réalisés en polyéthylène qui est une matière plastique peu coûteuse et présentant la souplesse désirée. Cependant, le polyéthylène ne peut pas être utilisé pour le conditionnement de tous les produits liquides. Certains produits, en particulier, des colorants capillaires ne peuvent pas être conservés dans du polyéthylène. On peut alors remplacer le polyéthylène par une autre matière plastique courante, peu coQteuse et ne posant pas de problème de conservation pour la substance liquide que l'on désire conditionner, à savoir le chlorure de polyvinyle ; mais, comme on le sait, le chlorure de polyvinyle est une matière rigide de sorte que les flacons ainsi réalisés ne présentent plus la souplesse recherchée et ne peuvent plus être comprimés alternativement sans trop d'efforts à l'aide des doigts pour produire de petits jets de liquide.Vials of this kind are conveniently made of polyethylene which is an inexpensive plastic material and having the desired flexibility. However, polyethylene cannot be used for the packaging of all liquid products. Certain products, in particular, hair dyes cannot be stored in polyethylene. The polyethylene can then be replaced by another common plastic material, inexpensive and not posing a conservation problem for the liquid substance which it is desired to condition, namely polyvinyl chloride; but, as we know, polyvinyl chloride is a rigid material so that the bottles thus produced no longer have the desired flexibility and can no longer be compressed alternately without too much effort using the fingers to produce small liquid jets.

La présente invention vise à réaliser un flacon en matériau rigide, notamment en chlorure de polyvinyle dont la paroi puisse cependant être aisément déformée à la main. Selon l'invention, on ménage sur la paroi du flacon au moins un pli s'étendant parallèlement à son axe et définissant un renfort qui en interrompant la périphérie du corps de flacon permet à cette dernière partie de se déformer. Ainsi, malgré l'emploi d'un matériau rigide, la paroi lisse du corps de flacon peut être comprimée manuellement.The present invention aims to produce a bottle made of rigid material, in particular polyvinyl chloride, the wall of which can however be easily deformed by hand. According to the invention, on the wall of the bottle is housed at least one fold extending parallel to its axis and defining a reinforcement which, by interrupting the periphery of the bottle body, allows the latter part to deform. Thus, despite the use of a rigid material, the smooth wall of the bottle body can be compressed manually.

La présente invention a donc pour objet un flacon à partie (s) pliante (s) ou souple (s) réalisé notamment en unma- tériau sensiblement rigide, le corps dudit flacon présentant sur sa paroi latérale, au moitis un pli s'étendant sensiblement parallèlement à l'axe du flacon, caractérisé par le tait que le pli susmentionné est réalisé de façon à constituer-unt partie sensiblement rigide permettant à la zone lisse restante de lapa- roi latérale de former une partie souple déformable manuellement.The subject of the present invention is therefore a bottle with a folding or flexible part (s) produced in particular from a substantially rigid material, the body of said bottle having on its side wall, in half a fold extending substantially parallel to the axis of the bottle, characterized by the fact that the aforementioned fold is produced so as to constitute a part substantially rigid allowing the remaining smooth area of the lateral section to form a flexible part which can be deformed manually.

Dans un mode préféré de réalisation, le flacon selon l'invention comporte deux plis sensiblement identiques, symétriques par rapport à l'axe du flacon ; chaque pli est prévu en creux sur la paroi latérale du corps de flacon ; il s'étend sensiblement sur toute la hauteur du corps de flacon et se termine d'une part, au voisinage de l'épaulement du corps de flacon où se raccorde le goulot et, d'autre part, au voisinage du fond dudit flacon.In a preferred embodiment, the bottle according to the invention comprises two substantially identical folds, symmetrical with respect to the axis of the bottle; each fold is provided in hollow on the side wall of the bottle body; it extends substantially over the entire height of the bottle body and ends on the one hand, in the vicinity of the shoulder of the bottle body where the neck is connected and, on the other hand, in the vicinity of the bottom of said bottle.

Chaque pli a avantageusement la configuration d'un sillon dont la section transversale perpendiculairement à l'axe du flacon, a la forme d'un V ; le sillon à section en V précité possède deux plans de symétrie : d'une part, un plan diamétral passant par l'arête intérieure du sillon et, d'autre part, le plan médian transversal du corps de flacon ; les deux arêtes extérieures de chaque sillon ne sont pas parallèles mais ont un écartement qui s'accroît progressivement en partant de l'extrémité du sillon située du coté de l'épaulement du corps de flacon jusqu'au milieu dudit corps environ pour décroître ensuite progressivement jusqu'à l'extrémité du sillon située du côté du fond du flacon ; la profondeur des sillons est aussi variable : elle s'accroît progressivement en partant de l'extrémité du sillon située du côté de l'épaulement du corps de flacon jusqu'au milieu dudit corps environ pour décroître ensuite progressivement jusqu'à l'extrémité du sillon située du côté du fond du flacon.Each fold advantageously has the configuration of a groove whose cross section perpendicular to the axis of the bottle, has the shape of a V; the groove with the aforementioned V section has two planes of symmetry: on the one hand, a diametral plane passing through the internal edge of the groove and, on the other hand, the transverse median plane of the bottle body; the two outer edges of each groove are not parallel but have a spacing which increases progressively from the end of the groove situated on the side of the shoulder of the bottle body to the middle of said body and then decreases gradually to the end of the groove located on the side of the bottom of the bottle; the depth of the furrows is also variable: it increases gradually from the end of the furrow located on the side of the shoulder of the bottle body to the middle of said body and then gradually decreases to the end of the groove located on the bottom side of the bottle.

Le flacon selon l'invention est avantageusement fabriqué par extrusion-soufflage ou injection-soufflage d'une matière plastique. Il est de préférence réalisé en chlorure de polyvinyle.The bottle according to the invention is advantageously produced by extrusion blow molding or injection blow molding of a plastic material. It is preferably made of polyvinyl chloride.

Le flacon selon l'invention peut porter sur sa paroi latérale une étiquette mise en place sur une machine à étiqueter. Une telle étiquette doit être apposée sur une partie lisse de la paroi latérale en dehors du (ou des) pli(s). Il convient, par suite, d'orienter convenablement le flacon à l'intérieur de la machine à étiqueter. Ainsi, suivant une autre particularité du flacon selon l'invention, le fond.de ce dernier comporte extérieurement, dans sa partie centrale, une nervure venue de moulage, permettant d'orienter le flacon à l'intérieur de la machine à étiqueter. Ce positionnement peut être effectué par engagement de la nervure précitée à l'intérieur d'une fente de forme complémentaire prévue sur le support des flacons à l'intérieur de la machine à étiqueter.The bottle according to the invention can carry on its side wall a label placed on a labeling machine. Such a label must be affixed on a smooth part of the side wall outside of the fold (s). It is therefore advisable to orient the bottle properly inside the labeling machine. Thus, according to another particularity of the bottle according to the invention, the bottom of the latter comprises externally, in its central part, a rib coming from molding, making it possible to orient the bottle con inside the labeling machine. This positioning can be carried out by engagement of the aforementioned rib inside a slot of complementary shape provided on the support of the bottles inside the labeling machine.

Selon une autre particularité, le goulot du flacon selon l'invention, comporte à sa périphérie une surépaisseur pourvue, du côté du rebord de goulot, d'une bordure crénelée. A l'intérieur des créneaux précités viennent s'imbriquer des créneaux de forme complémentaire pratiqués sur la paroi latérale intérieure d'une capsule.de bouchage se fixant par encliquetage sur ledit goulot.According to another particularity, the neck of the bottle according to the invention comprises at its periphery an additional thickness provided, on the side of the neck rim, with a crenellated border. Inside the abovementioned slots are nested slots of complementary shape formed on the inner side wall of a closure capsule. Which is snapped onto said neck.

Pour mieux faire comprendre l'objet de la présente invention, on va en décrire ci-après, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the present invention, there will be described below, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawing.

Sur ce dessin :

  • - la figure 1 est une vue en perspective éclatée d'un flacon selon l'invention ;
  • - la figure 2 est une coupe selon II-II du flacon de la figure 1, et
  • - la figure 3 est une coupe axiale de la partie inférieure du flacon représenté sur la figure 1.
On this drawing :
  • - Figure 1 is an exploded perspective view of a bottle according to the invention;
  • FIG. 2 is a section on II-II of the bottle of FIG. 1, and
  • - Figure 3 is an axial section of the lower part of the bottle shown in Figure 1.

En se référant au dessin, on voit que l'on a désigné par 1 un flacon de faible contenance pouvant renfermer, par exemple, une dose de produit capillaire, c'est-à-dire, la quantité juste nécessaire à une application sur les cheveux.Referring to the drawing, it can be seen that a small capacity bottle has been designated by 1 which can contain, for example, a dose of hair product, that is to say, the quantity just necessary for application to the hair.

Le flacon 1 est en chlorure de polyvinyle. Il est moulé par extrusion-soufflage.The bottle 1 is made of polyvinyl chloride. It is molded by extrusion blow molding.

Le corps cylindrique du flacon 1, dont le diamètre est petit par rapport à la hauteur, est raccordé par un épaulement 3 à un goulot 4, ce dernier présente à sa périphérie, sur environ la moitié de sa hauteur, une surépaisseur se terminant, du côté du rebord de goulot, par une bordure crénelée en dents de scie 4a. Entre le rebord du goulot et la bordure crénelée 4a précitée, est pratiquée une gorge périphérique 4b.The cylindrical body of the bottle 1, the diameter of which is small relative to the height, is connected by a shoulder 3 to a neck 4, the latter having at its periphery, over approximately half of its height, an extra thickness ending, of the side of the neck edge, by a serrated edge serrated 4a. Between the edge of the neck and the aforementioned crenellated border 4a, a peripheral groove 4b is made.

Une capsule de bouchage 5, en matière plastique, vient se fixer par encliquetage sur le goulot 4 du flacon. Elle présente aussi intérieurement, du côté de son fond circulaire 5a, une surépaisseur dont la bordure 5b définit des créneaux de forme complémentaire aux créneaux du goulot. La fixation de la capsule de bouchage 5 ---se fait par encliquetage d'un jonc annulaire intérieur (non représenté) de ladite capsule à l'intérieur de la gorge périphérique 4b du goulot ; dans cette position, les créneaux 5b de la capsule de bouchage sont imbriqués dans les créneaux 4a du goulot. L'ouverture du flacon est réalisée en faisant tourner la capsule de bouchage 5 par rapport au goulot 4, tandis que sa fermeture est obtenue par enfoncement de la capsule de bouchage 5 sur le goulot 4.A closure cap 5, made of plastic, is fixed by snap-fastening on the neck 4 of the bottle. She also has internally, on the side of its circular bottom 5a, an additional thickness, the edge 5b of which defines slots of complementary shape to the slots of the neck. The fixing of the stopper capsule 5 --- is done by snap-fastening of an inner annular rod (not shown) of said capsule inside the peripheral groove 4b of the neck; in this position, the slots 5b of the closure cap are nested in the slots 4a of the neck. The bottle is opened by rotating the closure cap 5 relative to the neck 4, while its closure is obtained by pressing the closure cap 5 onto the neck 4.

En variante, le goulot 4 peut être pourvu, de façon classique, d'un filetage extérieur coopérant avec le filetage intérieur ménagé sur la capsule de bouchage pour assurer la fixation par vissage de cette dernière sur le goulot du flacon.As a variant, the neck 4 can be provided, in a conventional manner, with an external thread cooperating with the internal thread formed on the stopper cap to ensure the screwing of the latter on the neck of the bottle.

Le goulot 4 du flacon reçoit une buse de distribution 6 dotée d'un orifice central 7, permettant de réduire le débit de liquide distribué par le flacon.The neck 4 of the bottle receives a dispensing nozzle 6 provided with a central orifice 7, making it possible to reduce the flow of liquid dispensed by the bottle.

La distribution de liquide se fait en comprimant alternativement à l'aide des doigts la paroi latérale 2 du flacon. Pour que cette dernière présente la souplesse requise, malgré la rigidité de la matière plastique en laquelle elle est réalisée, on prévoit deux plis 8 ayant les mêmes formes et dimensions, qui sont disposés symétriquement par rapport à l'axe du flacon ; chaque pli 8 s'étend longitudinalement, suivant une génératrice de la paroi latérale cylindrique 2, sur sensiblement toute la hauteur de ladite paroi latérale ; il se termine d'une part, en partie haute juste à proximité du fond du flacon et, d'autre part, en partie basse juste à proximité de l'épaulement 3.The liquid is dispensed by alternately compressing the side wall 2 of the bottle using the fingers. So that the latter has the required flexibility, despite the rigidity of the plastic material in which it is made, two folds 8 are provided having the same shapes and dimensions, which are arranged symmetrically with respect to the axis of the bottle; each fold 8 extends longitudinally, along a generatrix of the cylindrical side wall 2, over substantially the entire height of said side wall; it ends on the one hand, in the upper part just near the bottom of the bottle and, on the other hand, in the lower part just near the shoulder 3.

Chaque pli 8 a la configuration d'un sillon qui, en coupe transversale perpendiculaire à l'axe du flacon affecte la forme d'un V. Le sillon susmentionné comporte deux plans de symétrie : d'une part, un plan diamétral du flacon passant par l'arête intérieure 8a du sillon et, d'autre part, le plan médian transversal du corps de flacon.Each fold 8 has the configuration of a groove which, in cross section perpendicular to the axis of the bottle, takes the form of a V. The aforementioned groove has two planes of symmetry: on the one hand, a diametral plane of the passing bottle by the internal edge 8a of the groove and, on the other hand, the transverse median plane of the bottle body.

Selon une autre caractéristique, les deux arêtes extérieures 8b qui bordent le sillon ne sont pas parallèles :

  • leur écartement s'accroît progressivement en partant de l'extrémité du sillon située au voisinage de l'épaulement 3 jusqu'au milieu du corps de flacon où il atteint sa valeur maximum pour décroître ensuite progressivement jusqu'à l'extrémité du sillon disposée au voisinage du fond du flacon.
According to another characteristic, the two outer edges 8b which border the groove are not parallel:
  • their spacing increases gradually from the end of the groove located near the shoulder 3 to the middle of the bottle body where it reaches its maximum value, then decreases gradually until the end of the groove arranged at near the bottom of the bottle.

La profondeur des deux sillons varie de la même façon : elle croit progressivement depuis l'extrémité du sillon située au voisinage de l'épaulement 3 pour décroître ensuite progressivement jusqu'à l'extrémité du sillon située au voisinage du fond du flacon.The depth of the two furrows varies in the same way: it gradually increases from the end of the furrow located in the vicinity of the shoulder 3 to then gradually decrease to the end of the furrow located near the bottom of the bottle.

Grâce à cette configuration, le corps du flacon comporte deux parties rigides 8 disposées entre deux parties souples et lisses 9 (figure 2) ; les deux parties souples et lisses 9 présentent une souplesse maximum au milieu du corps du flacon, dans la zone où le sillon est le plus large et le plus profond.Thanks to this configuration, the body of the bottle has two rigid parts 8 disposed between two flexible and smooth parts 9 (Figure 2); the two flexible and smooth parts 9 have maximum flexibility in the middle of the body of the bottle, in the area where the groove is the widest and deepest.

En appuyant sur les parties souples et lisses 9 du corps de flacon, l'utilisateur provoque leur aplatissement. On observe que la présence des deux sillons, de forme particulière, confère au flacon la souplesse recherchée. On observe aussi qu'en appuyant à l'endroit des sillons 8, les parties lisses et souples 9 du flacon se déforment également. Par conséquent, il n'est pas nécessaire d'exercer une pression à un endroit précis du corps de flacon ; quelle que soit la zone d'appui, il se produit une déformation de la paroi du corps de flacon, permettant dans tous les cas, la distribution sous forme de petits jets, du liquide contenu dans le flacon.By pressing on the flexible and smooth parts 9 of the bottle body, the user causes them to flatten. It is observed that the presence of the two grooves, of particular shape, gives the bottle the desired flexibility. It is also observed that by pressing at the location of the grooves 8, the smooth and flexible parts 9 of the bottle are also deformed. Therefore, there is no need to exert pressure at a specific location on the vial body; whatever the support zone, a deformation of the wall of the bottle body occurs, allowing in all cases, the distribution in the form of small jets, of the liquid contained in the bottle.

Une nervure extérieure 11, sensiblement rectiligne, est prévue en relief dans la partie centrale courbe concave du fond 10 du flacon. Elle s'étend sensiblement, dans cet exemple, perpendiculairement au plan axial passant par les deux arêtes 8a, des deux sillons. Elle permet, sur une machine à étiqueter, de positionner une étiquette sur l'une des parties souples et lisses 9 du flacon.An outer rib 11, substantially rectilinear, is provided in relief in the concave curved central part of the bottom 10 of the bottle. It extends substantially, in this example, perpendicular to the axial plane passing through the two edges 8a, of the two grooves. It allows, on a labeling machine, to position a label on one of the flexible and smooth parts 9 of the bottle.

Il est bien entendu que le mode de réalisation ci-dessus décrit n'est aucunement limitatif et pourra donner lieu à toutes modifications désirables sans sortir pour cela du cadre de l'invention.It is understood that the embodiment described above is in no way limiting and may give rise to any desirable modifications without departing from the scope of the invention.
