This elongation rod thus occupies a space centered on the central axis C inside the container during its formation. Consequently, the position 5 millimeters or more from the central axis C of the deepest point(s) avoids contact between the boxed recess and the elongation rod.

Description

Le domaine de l'invention est celui de la conception et de la fabrication de récipients en matière plastique.The field of the invention is that of the design and manufacture of plastic containers.

Plus précisément, l'invention a trait aux récipients obtenus par soufflage ou étirage-soufflage à partir d'ébauches (préformes, ou récipients intermédiaires ayant subis une ou plusieurs opérations préalables de soufflage) en matière plastique.More precisely, the invention relates to containers obtained by blowing or stretch-blowing from blanks (preforms, or intermediate containers having undergone one or more prior blowing operations) made of plastic.

La fabrication par soufflage d'un récipient comprend une étape d'introduction, dans un moule à l'empreinte du récipient, d'une ébauche préalablement chauffée à une température supérieure à la température de transition vitreuse de la matière constitutive de la préforme (tel que PET), et une étape d'injection dans l'ébauche d'un fluide (tel que de l'air) sous pression. Un étirage au moyen d'une tige coulissante peut compléter le soufflage.The manufacturing of a container by blowing comprises a step of introducing, into a mold in the shape of the container, a blank previously heated to a temperature higher than the glass transition temperature of the material constituting the preform (such such as PET), and a step of injecting a fluid (such as air) under pressure into the blank. Stretching using a sliding rod can complete the blowing.

Un récipient ainsi obtenu présente une forme définie par un corps s'étendant entre un fond et une ouverture.A container thus obtained has a shape defined by a body extending between a bottom and an opening.

La préhension de tels récipients peut être plus ou moins aisée en fonction de la forme et du volume du récipient, ainsi que de la taille des mains de la personne qui souhaite se saisir du récipient.Gripping such containers may be more or less easy depending on the shape and volume of the container, as well as the size of the hands of the person who wishes to grasp the container.

Pour faciliter la préhension du récipient, il est connu de réaliser une ou plusieurs poignées de préhension directement sur le corps du récipient.To facilitate gripping the container, it is known to make one or more gripping handles directly on the body of the container.

Dans ce cas, la poignée est réalisée sur le corps du récipient, pendant la formation de ce dernier. A cet effet, le moule dans lequel le récipient est soufflé présente des inserts, dits inserts de boxage d'une poignée, qui sont mobiles au travers de parois du moule.In this case, the handle is made on the body of the container, during the formation of the latter. For this purpose, the mold in which the container is blown has inserts, called handle boxing inserts, which are movable through the walls of the mold.

Le procédé de fabrication d'un récipient avec une poignée de préhension comprend une étape de boxage d'une poignée à l'aide des inserts. Le boxage consiste à repousser une zone de matière vers l'intérieur du récipient, de façon à former une poignée en forme de creux sur la paroi. La poignée est formée en rapprochant deux portions d'une paroi du récipient lors de sa formation sous l'action des inserts de boxage. Les inserts de boxage déforment ainsi la matière plastique encore ramollie.The method of manufacturing a container with a gripping handle includes a step of boxing a handle using the inserts. Boxing consists of pushing an area of material towards the inside of the container, so as to form a hollow-shaped handle on the wall. The handle is formed by bringing together two portions of a wall of the container during its formation under the action of the boxing inserts. The boxing inserts thus deform the still softened plastic material.

Le boxage permet la réalisation d'un renfoncement présentant une profondeur importante sur la paroi du corps. La profondeur de ce renfoncement n'est pas atteignable par le seul soufflage du récipient dans son moule.Boxing allows the creation of a recess having a significant depth on the wall of the body. The depth of this recess cannot be reached by simply blowing the container into its mold.

Il est connu de l'art antérieur des récipients comprenant une poignée de préhension boxée, tels que ceux décrits dans le document de brevet publié sous le numéro US10086969B2 . Les récipients décrits dans ce document comprennent une poignée de préhension formée grâce à deux renfoncements boxés présentés par le corps, se faisant face, et rapprochant ainsi, l'une de l'autre, deux portions opposées de la paroi du corps du récipient. La poignée boxée permet à une personne de saisir plus aisément le récipient, en insérant son pouce dans l'un des renfoncements boxés, en entourant la poignée de sa main, et en insérant ses autres doigts dans l'autre renfoncement boxé. L'utilisateur peut ainsi se saisir de la poignée pour soulever le récipient. Le document JP2017128348A décrit un récipient selon le préambule de la revendication 1.It is known from the prior art containers comprising a boxed gripping handle, such as those described in the patent document published under the number US10086969B2 . The containers described in this document include a gripping handle formed by two boxed recesses presented by the body, facing each other, and thus bringing two opposite portions of the wall of the body of the container closer to each other. The boxed handle allows a person to more easily grip the container by inserting their thumb into one of the boxed recesses, wrapping their hand around the handle, and inserting their other fingers into the other boxed recess. The user can thus grab the handle to lift the container. The document JP2017128348A describes a container according to the preamble of claim 1.

Dans le domaine de l'invention, il est également connu le document de brevet publié sous le numéro EP3112280A1 . Ce document décrit un récipient d'une grande contenance et muni d'une poignée. La poignée est formée par deux renfoncements boxés sur le corps, en vis-à-vis l'un de l'autre et situés sur un côté du récipient. La poignée est ainsi excentrée sur le contenant pour permettre à une personne d'insérer ses doigts dans les renfoncements boxés pour saisir le récipient. Les renfoncements sont boxés de manière symétrique pour permettre une préhension de la bouteille par une main droite ou une main gauche.In the field of the invention, it is also known the patent document published under the number EP3112280A1 . This document describes a container with a large capacity and fitted with a handle. The handle is formed by two boxed recesses on the body, facing each other and located on one side of the container. The handle is thus off-centered on the container to allow a person to insert their fingers into the boxed recesses to grasp the container. The recesses are boxed symmetrically to allow the bottle to be gripped by a right or left hand.

Les poignées décrites dans ces documents simplifient la préhension des contenants. Ce type de conception de poignée présente néanmoins plusieurs inconvénients.The handles described in these documents simplify gripping containers. This type of handle design, however, has several disadvantages.

En effet, la réalisation d'une telle poignée entraîne une surconsommation de matière plastique pour la formation du récipient. Plus précisément, par rapport au formage d'un récipient sans boxage, la réalisation d'un boxage nécessite une quantité plus importante de plastique pour permettre une bonne déformation du matériau plastique ramolli.In fact, the production of such a handle leads to excess consumption of plastic material for the formation of the container. More precisely, compared to forming a container without boxing, producing boxing requires a larger quantity of plastic to allow good deformation of the softened plastic material.

Il en résulte ainsi une augmentation, bien que faible, de la masse du récipient, ce qui s'avère indésirable et clairement contraire aux tendances actuelles d'économies de matières. Pour certaines applications dont le coût de l'emballage est prédominant sur le coût total du produit, cette augmentation de masse se révèle problématique.This thus results in an increase, although slight, in the mass of the container, which turns out to be undesirable and clearly contrary to current trends in material savings. For certain applications where the cost of packaging is predominant over the total cost of the product, this increase in mass proves problematic.

De plus, ce double boxage entraîne des contraintes pour la conception du moule utilisé pour former le récipient, et pour le positionnement vertical des inserts de boxage par rapport au moule.In addition, this double boxing causes constraints for the design of the mold used to form the container, and for the vertical positioning of the boxing inserts relative to the mold.

Plus précisément, lors du formage du récipient, une compensation pneumatique de la pression de soufflage est mise en oeuvre. La pression de soufflage correspond à l'air injecté dans une préforme mise en place dans le moule pour produire le récipient. Cette pression de soufflage tend à écarter deux parties du moule plaquées l'une contre l'autre pour former le moule. La compensation pneumatique consiste à injecter de l'air dans une chambre ménagée entre l'une des parties du moule et son support pour contrecarrer la pression de soufflage. La chambre est délimitée entre la partie du moule et son support par un joint de compensation. Le joint est agencé afin que la surface projetée de la chambre de compensation soit au moins égale à celle du récipient prise dans un plan parallèle à l'axe longitudinal du récipient. Pour des raisons de coût de production notamment, la zone de compensation, qui était personnalisée par le passé dans les machines de la demanderesse, est désormais standardisée et la chambre de compensation possède une position et des dimensions qui sont les mêmes quelle que soit la surface projetée de la bouteille. Pour des raisons liées à la conception du moule de son support, la hauteur de la chambre est en général inférieure à celle du récipient (la hauteur est la dimension prise selon l'axe longitudinal du récipient) et la largeur de la chambre est supérieure pour que la surface projetée de la chambre soit au moins égale à celle du récipient. En conséquence, le fond du récipient, son col et une partie de l'épaule sont en regard de l'extérieur de la chambre de compensation.More precisely, during the forming of the container, pneumatic compensation of the blowing pressure is implemented. The blowing pressure corresponds to the air injected into a preform placed in the mold to produce the container. This blowing pressure tends to push apart two parts of the mold pressed against each other to form the mold. Pneumatic compensation consists of injecting air into a chamber between one of the parts of the mold and its support to counteract the blowing pressure. The chamber is delimited between the part of the mold and its support by a compensation joint. The joint is arranged so that the projected surface of the compensation chamber is at least equal to that of the container taken in a plane parallel to the longitudinal axis of the container. For reasons of production cost in particular, the compensation zone, which was personalized in the past in the applicant's machines, is now standardized and the compensation chamber has a position and dimensions which are the same whatever the surface. projected from the bottle. For reasons linked to the design of the mold and its support, the height of the chamber is generally less than that of the container (the height is the dimension taken along the longitudinal axis of the container) and the width of the chamber is greater for that the projected surface of the chamber is at least equal to that of the container. Consequently, the bottom of the container, its neck and part of the shoulder face the outside of the clearing chamber.

Dans ce cadre, si un double boxage doit être réalisé, alors l'insert de boxage équipant la partie de moule compensé doit se mouvoir à l'intérieur du périmètre défini par le joint de compensation. A titre d'exemple, dans une réalisation de la demanderesse, l'insert de boxage traversant la partie de moule compensée doit présenter un positionnement vertical tel que l'axe de la poignée de préhension produite ne peut pas être positionné à moins de 97mm du col du récipient.In this context, if double boxing must be carried out, then the boxing insert fitted to the compensated mold part must move within the perimeter defined by the compensation joint. By way of example, in one embodiment of the applicant, the boxing insert passing through the compensated mold part must have a vertical positioning such that the axis of the gripping handle produced cannot be positioned less than 97mm from the neck of the container.

Enfin, une telle poignée formée par deux renfoncements boxés sur le corps ne s'avère pas optimale pour les bouteilles de plus petit diamètre. En effet, la poignée s'en trouve en définitive peu ergonomique. Cela résulte du fait que l'arrière de la préhension et le développé de préhension sont obligatoirement réduits.Finally, such a handle formed by two boxed recesses on the body is not optimal for bottles of smaller diameter. In fact, the handle is ultimately not very ergonomic. This results from the fact that the back of the grip and the grip development are necessarily reduced.

L'invention a notamment pour objectif de pallier les inconvénients de l'art antérieur.The invention aims in particular to overcome the disadvantages of the prior art.

Plus précisément, l'invention a pour objectif de proposer un récipient disposant d'une poignée de préhension dont la conception limite la surconsommation de matériau plastique lors de la fabrication du récipient, et ce notamment par rapport aux récipients selon l'art antérieur présentant une poignée de préhension formée par un double boxage.More precisely, the invention aims to propose a container having a gripping handle whose design limits the overconsumption of plastic material during the manufacture of the container, and this in particular compared to containers according to the prior art having a gripping handle formed by double boxing.

L'invention a également pour objectif de fournir un tel récipient qui puisse être saisi indifféremment et tout aussi aisément par la main droite ou la main gauche d'un consommateur.The invention also aims to provide such a container which can be grasped equally and just as easily by the right hand or the left hand of a consumer.

Ces objectifs, ainsi que d'autres qui apparaitront par la suite, sont atteints grâce à l'invention qui a pour objet un récipient en matière plastique comprenant un corps s'étendant selon un axe central entre une ouverture et un fond, le corps présentant un renfoncement boxé de préhension s'étendant parallèlement à l'axe central sur une hauteur prédéterminée H, le renfoncement boxé de préhension étant le seul renfoncement boxé sur le corps sur la hauteur prédéterminée, et présente :

  • une ligne médiane d'enfoncement maximal ;
  • une bordure latérale droite et une bordure latérale gauche encadrant la ligne médiane d'enfoncement maximal ;
la ligne médiane d'enfoncement maximal s'inscrivant dans un plan diamétral équidistant de la bordure latérale droite et de la bordure latérale gauche, caractérisé en ce que le corps présente un premier développé et un second développé de part et d'autre du plan diamétral P du corps, entre au moins un point le plus profond de la ligne médiane d'enfoncement maximal et un point diamétralement opposé audit point le plus profond, les longueurs du premier développé et du second développé étant chacune comprises de 100 à 160 millimètres,et en ce que le renfoncement boxé de préhension présente de part et d'autre de la ligne médiane d'enfoncement maximal un pan latéral droit et un pan latéral gauche s'inscrivant respectivement dans un premier plan (L1) et un second plan (L2) qui se croisent selon un angle d'ouverture compris entre 25° et 45°.These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which relates to a plastic container comprising a body extending along a central axis between an opening and a bottom, the body having a boxed gripping recess extending parallel to the central axis over a predetermined height H, the boxed gripping recess being the only boxed recess on the body over the predetermined height, and has:
  • a center line of maximum depression;
  • a right side border and a left side border framing the center line of maximum depression;
the median line of maximum depression falling into a diametrical plane equidistant from the right lateral border and the left lateral border, characterized in that the body has a first developed and a second developed on either side of the diametrical plane P of the body, between at least one deepest point of the center line of maximum depression and a point diametrically opposite said deepest point, the lengths of the first developed and the second developed each being between 100 and 160 millimeters, and in that the boxed gripping recess has on either side of the center line of maximum depression a right side panel and a left side panel falling respectively into a first plane (L1) and a second plane (L2) which intersect at an opening angle of between 25° and 45°.

Grâce à l'invention, le récipient dispose d'une poignée de préhension constituée par la forme même du corps sur sa hauteur prédéterminée H. En effet, sur cette hauteur prédéterminée H, le corps présente un renfoncement boxé de préhension unique permettant d'améliorer la préhension du corps du récipient.Thanks to the invention, the container has a gripping handle constituted by the shape of the body itself on its predetermined height H. In fact, on this predetermined height H, the body has a unique boxed gripping recess making it possible to improve gripping the body of the container.

Selon le principe de l'invention, la poignée de préhension permet de « pincer » le récipient pour s'en saisir. Le renfoncement boxé de préhension s'étend sur la hauteur prédéterminée et fournit ainsi un logement dans lequel au moins l'un des doigts d'une main (par exemple un ou plusieurs des doigts à l'exception du pouce ou, au contraire, seulement le pouce) peut venir s'insérer. La main peut alors se refermer sur le corps du récipient pour que le pouce vienne en opposition par rapport au corps du récipient, vis-à-vis du ou des autres doigts. La pince ainsi formée par la main permet un saisissement efficace du récipient, pour un droitier ou un gaucher, à l'aide de l'unique renfoncement boxé.According to the principle of the invention, the gripping handle makes it possible to “pinch” the container to grasp it. The boxed gripping recess extends over the predetermined height and thus provides a housing in which at least one of the fingers of a hand (for example one or more of the fingers with the exception of the thumb or, on the contrary, only the thumb) can be inserted. The hand can then close on the body of the container so that the thumb comes into opposition relation to the body of the container, with respect to the other finger(s). The clamp thus formed by the hand allows effective gripping of the container, for a right-handed or a left-handed person, using the unique boxed recess.

Cette préhension est notamment ergonomique sur des récipients présentant un petit diamètre (inférieur à 100 mm).This grip is particularly ergonomic on containers with a small diameter (less than 100 mm).

En conséquence, il n'y a pas d'autre renfoncement boxé de préhension sur la hauteur prédéterminée H à part le premier et unique renfoncement boxé de préhension. Ainsi, la formation du récipient entraîne seulement une légère surconsommation de matériau plastique pour la formation d'autres renfoncements boxés de préhension. Un récipient selon l'invention peut ainsi être allégé par rapport à un récipient présentant une poignée de préhension formée par un double boxage.Consequently, there is no other boxed gripping recess on the predetermined height H apart from the first and only boxed gripping recess. Thus, the formation of the container only results in a slight excess consumption of plastic material for the formation of other boxed gripping recesses. A container according to the invention can thus be lighter compared to a container having a gripping handle formed by double boxing.

De plus, la réalisation d'un unique boxage pour former la poignée de préhension offre une plus grande latitude de conception du moule pour le récipient d'une part, et des possibilités accrues dans le design de l'emballage puisque la plage de positionnement de l'insert mobile est plus importante, d'autre part. Cela résulte du fait que l'insert de boxage réalisant le renfoncement boxé de préhension peut être mobile au travers de la partie du moule qui n'est pas compensée. Ainsi, l'insert de boxage traversant la partie de moule non-compensée peut présenter un positionnement vertical tel que la poignée de préhension produite peut se trouver, relativement au récipient, à une hauteur supérieure à celle qui est permise pour les récipients avec une poignée de préhension formée par double boxage, avec un moule pneumatiquement compensé. Si on compare avec l'exemple mentionné auparavant dans lequel la poignée de préhension ne pouvait pas posséder de zone se trouvant à moins de 97mm du col de l'ébauche, l'invention permet de réduire drastiquement cette distance : le renfoncement boxé de préhension peut se trouver beaucoup plus près du col du récipient.In addition, the production of a single boxing to form the gripping handle offers greater latitude in designing the mold for the container on the one hand, and increased possibilities in the design of the packaging since the positioning range of the mobile insert is more important, on the other hand. This results from the fact that the boxing insert producing the boxed gripping recess can be movable through the part of the mold which is not compensated. Thus, the boxing insert passing through the non-compensated mold part can have a vertical positioning such that the gripping handle produced can be found, relative to the container, at a height greater than that which is permitted for containers with a handle grip formed by double boxing, with a pneumatically compensated mold. If we compare with the example mentioned previously in which the gripping handle could not have a zone located less than 97mm from the neck of the blank, the invention makes it possible to drastically reduce this distance: the boxed gripping recess can be much closer to the neck of the container.

Il peut également être noté que la formation d'une poignée de préhension à l'aide d'un unique boxage, et non de deux boxages, est moins consommateur en énergie du fait qu'il n'y a qu'un seul insert de boxage à mettre en mouvement. De plus, cette solution, dans la mesure où elle ne nécessite qu'un insert dans un moule (préférentiellement le demi-moule non compensé), est moins coûteuse que celles mettant en oeuvre un double boxage qui, elles, nécessitent deux inserts par moule (un insert dans chaque demi-moule).It can also be noted that the formation of a gripping handle using a single boxing, and not two boxings, consumes less energy due to the fact that there is only one insert of boxing to put in motion. Furthermore, this solution, to the extent that it only requires one insert in a mold (preferably the uncompensated half-mold), is less expensive than those implementing double boxing which require two inserts per mold. (one insert in each half-mold).

Selon une caractéristique préférentielle, au moins un point le plus profond de la ligne médiane d'enfoncement maximal est situé à 15 mm ou moins de l'axe central C.According to a preferred characteristic, at least one deepest point of the center line of maximum depression is located 15 mm or less from the central axis C.

Le renfoncement boxé de préhension présente alors une profondeur suffisamment importante pour une insertion optimale des doigts d'une main, quel que soit le format de la bouteille, et permettre la réalisation d'une pince à l'aide d'une main sur le récipient.The boxed gripping recess then has a sufficiently large depth for optimal insertion of the fingers of one hand, whatever the format of the bottle, and to allow the creation of a gripper using one hand on the container. .

La ligne médiane d'enfoncement maximal décrit le profil du renfoncement boxé dans le plan diamétral. Le (ou les) point le plus profond correspond au point le long de cette ligne médiane d'enfoncement maximal qui est le plus proche de l'axe central C ou qui dépassent le plus l'axe central C dans le plan diamétral, par rapport aux autres points constituant la ligne médiane d'enfoncement maximal. Ainsi, si la ligne médiane d'enfoncement maximal présente à sa profondeur maximale une section droite parallèle à l'axe central C, alors les points constituant cette section droite sont les points le plus profonds de la ligne médiane d'enfoncement maximal.The maximum indentation center line describes the profile of the boxed indentation in the diametrical plane. The deepest point(s) corresponds to the point along this center line of maximum depression which is closest to the central axis C or which extends most beyond the central axis C in the diametrical plane, relative to at the other points constituting the center line of maximum depression. Thus, if the center line of maximum depression has at its maximum depth a straight section parallel to the central axis C, then the points constituting this straight section are the deepest points of the center line of maximum depression.

Avantageusement, le ou les points le plus profond sont situés à 5 mm ou plus de l'axe central C.Advantageously, the deepest point(s) are located 5 mm or more from the central axis C.

De cette manière avantageuse, la création du renfoncement boxé de préhension lors de la formation du récipient par étirage-soufflage ne nécessite pas un réglage non conventionnel de la course de la tige d'élongation servant à étirer et maintenir le récipient. Plus précisément, lors du soufflage, la tige d'élongation s'étend à l'intérieur de la préforme selon l'axe central C pour s'assurer qu'un point amorphe de la préforme soit bien maintenu au fond du moule. Cette tige d'élongation occupe ainsi un espace centré sur l'axe central C à l'intérieur du récipient lors de sa formation. En conséquence, la position à 5 millimètres ou plus de l'axe central C du ou des points le plus profond évite un contact entre le renfoncement boxé et la tige d'élongation. Il n'y a ainsi pas besoin de remonter précocement la tige d'élongation pour permettre un boxage du renfoncement boxé de préhension qui s'étendrait en regard de la course de la tige d'élongation.In this advantageous manner, the creation of the boxed gripping recess during the formation of the container by stretch-blowing does not require unconventional adjustment of the stroke of the elongation rod used to stretch and hold the container. More precisely, during blowing, the elongation rod extends inside the preform along the central axis C to ensure that an amorphous point of the preform is well maintained at the bottom of the mold. This elongation rod thus occupies a space centered on the central axis C inside the container during its formation. Consequently, the position 5 millimeters or more from the central axis C of the deepest point(s) avoids contact between the boxed recess and the elongation rod. There is thus no need to raise the elongation rod early to allow boxing of the boxed gripping recess which would extend opposite the stroke of the elongation rod.

Selon l'invention, le corps présente un premier développé et un second développé de de part et d'autre du plan diamétral P du corps, entre ledit point le plus profond et un point diamétralement opposé audit point le plus profond, le premier développé et le second développé étant chacun compris de 100 à 160 millimètres.According to the invention, the body has a first developed and a second developed on either side of the diametrical plane P of the body, between said deepest point and a point diametrically opposite said deepest point, the first developed and the second developed each being between 100 and 160 millimeters.

La poignée de préhension du récipient se trouve ainsi particulièrement ergonomique.The handle for gripping the container is thus particularly ergonomic.

Selon une conception préférée, le corps est symétrique par rapport au plan diamétral sur la hauteur prédéterminée H.According to a preferred design, the body is symmetrical with respect to the diametrical plane over the predetermined height H.

Grâce à cette conception, le récipient peut être saisi de la main droite ou de la main gauche, indifféremment et tout aussi aisément.Thanks to this design, the container can be grasped with the right or left hand, equally and just as easily.

Selon l'invention, le renfoncement boxé de préhension présente de part et d'autre de la ligne médiane d'enfoncement maximal un pan latéral droit et un pan latéral gauche s'inscrivant respectivement dans un premier plan et un second plan qui se croisent selon un angle d'ouverture compris entre 25° et 45°.According to the invention, the boxed gripping recess has on either side of the center line of maximum depression a right side panel and a left side panel respectively fitting into a first plane and a second plane which intersect according to an opening angle of between 25° and 45°.

Une telle ouverture du renfoncement boxé de préhension favorise l'insertion correcte d'au moins un des doigts d'une personne, qu'elle soit droitière ou gauchère.Such an opening of the boxed gripping recess promotes the correct insertion of at least one of the fingers of a person, whether right-handed or left-handed.

En deçà de 25°, l'insertion s'au moins un des doigts dans le renfoncement boxé devient malaisée, et au-delà de 45° la préhension du récipient à l'aide de la poignée n'est plus aisée ni efficace.Below 25°, the insertion of at least one of the fingers into the boxed recess becomes difficult, and beyond 45° gripping the container using the handle is no longer easy or effective.

Selon une caractéristique avantageuse, le corps présente, sur sa hauteur prédéterminée H et le long de l'axe central C une section transversale qui s'inscrit à l'intérieur d'un cercle dont le diamètre diminue depuis une extrémité haute de la hauteur prédéterminée, puis qui augmente jusqu'à une extrémité basse de la hauteur prédéterminée.According to an advantageous characteristic, the body has, on its predetermined height H and along the central axis C, a cross section which fits inside a circle whose diameter decreases from a high end of the predetermined height , then which increases to a lower end of the predetermined height.

Cette diminution du diamètre du cercle dans lequel s'inscrit le corps induit une diminution du développé minimum nécessaire pour pouvoir saisir le récipient à l'aide d'une main.This reduction in the diameter of the circle in which the body fits induces a reduction in the minimum development necessary to be able to grasp the container with one hand.

Le corps présente ainsi sur sa hauteur prédéterminée des dimensions plus restreintes qui facilitent la préhension du récipient à l'aide d'une main.The body thus has more restricted dimensions at its predetermined height which make it easier to grip the container with one hand.

En effet, lorsqu'une personne saisit le récipient, il insère des doigts (par exemple de l'index à l'auriculaire) dans le renfoncement boxé de préhension et entoure le corps du reste de sa paume pour venir positionner son pouce en opposition par rapport au corps et former une pince. Alternativement, bien que ceci soit moins naturel, la personne peut saisir le récipient en insérant son pouce dans le renfoncement boxé de préhension et entourer le corps du reste de sa paume pour venir positionner ses autres doigts en opposition par rapport au corps et former une pince.Indeed, when a person grasps the container, he inserts fingers (for example from the index finger to the little finger) in the boxed gripping recess and surrounds the body with the rest of his palm to position his thumb in opposition to relative to the body and form a clamp. Alternatively, although less natural, the person can grasp the container by inserting their thumb into the boxed gripping recess and surround the body with the rest of their palm to come and position the other fingers in opposition to the body and form a clamp.

Selon une solution préférentielle, le corps présente sur sa hauteur prédéterminée H un rétreint de positionnement d'un doigt diamétralement opposé au renfoncement boxé de préhension, dont la fonction est de recevoir un doigt afin de faciliter la préhension du récipient, comme expliqué ci-après.According to a preferred solution, the body has on its predetermined height H a constriction for positioning a finger diametrically opposite the boxed gripping recess, the function of which is to receive a finger in order to facilitate gripping of the container, as explained below .

Un tel rétreint de positionnement facilite la préhension du récipient à l'aide d'une main : en effet, des essais ont permis de constater que lors de la préhension du récipient, le pouce vient se loger naturellement dans ce rétreint de positionnement pendant qu'au moins un autre doigt vient se loger naturellement dans le renfoncement boxé de préhension.Such a positioning constriction makes it easier to grip the container using one hand: in fact, tests have shown that when gripping the container, the thumb is naturally lodged in this positioning constriction while at least one other finger fits naturally into the boxed gripping recess.

Préférentiellement, dans le cas d'emballages particulièrement allégés, le corps présente au moins sur sa hauteur prédéterminée H des corrugations annulaires de renfort, le rétreint de positionnement étant positionné entre deux corrugations annulaires.Preferably, in the case of particularly lightweight packaging, the body has at least over its predetermined height H annular reinforcement corrugations, the positioning constriction being positioned between two annular corrugations.

Le corps est ainsi renforcé sur sa hauteur prédéterminée H, évitant ainsi une fragilité du récipient du fait de la présence du rétreint de positionnement. Un tel renforcement est notamment important lorsque l'emballage nécessite une résistance que son poids et donc l'épaisseur de PET disponible ne peuvent lui permettre d'atteindre.The body is thus reinforced on its predetermined height H, thus avoiding fragility of the container due to the presence of the positioning restriction. Such reinforcement is particularly important when the packaging requires a resistance that its weight and therefore the thickness of available PET cannot allow it to achieve.

De plus, le rétreint de positionnement est alors intégré visuellement sur le corps.In addition, the positioning restriction is then visually integrated onto the body.

Avantageusement, dans le plan diamétral et selon une projection orthogonale sur l'axe central C, le rétreint de positionnement est situé au-dessus de la mi-hauteur du renfoncement boxé de préhension.Advantageously, in the diametrical plane and in an orthogonal projection on the central axis C, the positioning constriction is located above mid-height of the boxed gripping recess.

La préhension du récipient est ainsi encore plus aisée et confortable. En effet, cette disposition du rétreint de positionnement par rapport au renfoncement boxé de préhension respecte alors la morphologie d'une main et le geste classiquement réalisé pour se saisir d'un objet.Gripping the container is thus even easier and more comfortable. Indeed, this arrangement of the positioning constriction in relation to the boxed gripping recess then respects the morphology of a hand and the gesture conventionally made to grasp an object.

Selon un mode de réalisation avantageux, la ligne médiane d'enfoncement maximal est convexe vers l'axe central C, entre une extrémité haute et une extrémité basse éloignées de l'axe central C, la ligne médiane d'enfoncement maximal présentant successivement à partir de l'extrémité haute :

  • une première portion présentant un rayon de courbure R1 ;
  • une seconde portion présentant un rayon de courbure R2 ;
le rayon de courbure R1 étant inférieur au rayon de courbure R2.According to an advantageous embodiment, the median line of maximum depression is convex towards the central axis C, between a high end and a low end distant from the central axis C, the median line of maximum depression presenting successively from from the upper end:
  • a first portion having a radius of curvature R1;
  • a second portion having a radius of curvature R2;
the radius of curvature R1 being less than the radius of curvature R2.

Selon ce mode de réalisation, le renfoncement boxé de préhension présente un profil favorisant une saisie du récipient à l'aide de la poignée formée sur le corps. En effet, en présentant un rayon de courbure inférieur à celui de la seconde portion, la première portion de la ligne médiane d'enfoncement maximal forme une butée plus importante que celle formée par la seconde portion. Ceci améliore la manière dont le poids du récipient s'exerce sur la partie haute du ou des doigts insérés dans le renfoncement boxé de préhension, Ceci correspond par ailleurs de façon logique au profil offert par les longueurs des quatre doigts de la main, autres que le pouce, lorsqu'ils sont tous insérés dans le renfoncement boxé.According to this embodiment, the boxed gripping recess has a profile favoring gripping the container using the handle formed on the body. Indeed, by presenting a radius of curvature less than that of the second portion, the first portion of the center line of maximum depression forms a greater stop than that formed by the second portion. This improves the way in which the weight of the container is exerted on the upper part of the finger(s) inserted in the boxed gripping recess. This also logically corresponds to the profile offered by the lengths of the four fingers of the hand, other than the thumb, when they are all inserted into the boxed recess.

Selon un autre mode de réalisation avantageux, la ligne médiane d'enfoncement maximal est convexe vers l'axe central C, entre une extrémité haute et une extrémité basse éloignées de l'axe central C, la ligne médiane d'enfoncement maximal présentant successivement à partir de l'extrémité haute :

  • une première portion courbée ;
  • une portion intermédiaire essentiellement droite ;
  • une seconde portion courbée.
According to another advantageous embodiment, the median line of maximum depression is convex towards the central axis C, between a high end and a low end distant from the central axis C, the median line of maximum depression having successively at from the top end:
  • a first curved portion;
  • an essentially straight intermediate portion;
  • a second curved portion.

Cette conception forme un logement permettant d'accueillir de manière ergonomique dans le renfoncement boxé de préhension tous les doigts à l'exception du pouce lors de la préhension du récipient.This design forms a housing allowing all fingers except the thumb to be ergonomically accommodated in the boxed gripping recess when gripping the container.

Tel que visible sur les figures 1, 2, 3 et 5, un récipient 1 selon l'invention comprend un corps 10 qui s'étend selon un axe central C entre une ouverture 11 et un fond 12.As visible on the figures 1 , 2 , 3 And 5 , a container 1 according to the invention comprises a body 10 which extends along a central axis C between an opening 11 and a bottom 12.

L'ouverture 11 est classiquement présente à l'extrémité d'un col 13 situé au-dessus d'une épaule 14 surmontant le corps 10.The opening 11 is conventionally present at the end of a collar 13 located above a shoulder 14 surmounting the body 10.

Plus particulièrement, le récipient 1 est, selon les modes de réalisation illustrés, une bouteille fabriquée à partir d'un matériau thermoplastique tel que le PET (acronyme de polyéthylène téréphtalate).More particularly, the container 1 is, according to the illustrated embodiments, a bottle made from a thermoplastic material such as PET (acronym for polyethylene terephthalate).

Le récipient 1, présente un renfoncement boxé de préhension 2. Ce renfoncement boxé de préhension 2 s'étend parallèlement à l'axe central C sur une hauteur prédéterminée H.The container 1 has a boxed gripping recess 2. This boxed gripping recess 2 extends parallel to the central axis C over a predetermined height H.

Un tel renfoncement boxé est réalisé lors de la fabrication du récipient 1 à l'aide d'un insert de boxage qui vient déformer la matière plastique préalablement chauffée et soufflée dans une cavité de moulage d'un moule, à la forme du récipient à obtenir, en pénétrant à l'intérieur du moule.Such a boxed recess is produced during the manufacture of the container 1 using a boxing insert which deforms the plastic material previously heated and blown into a molding cavity of a mold, to the shape of the container to be obtained , penetrating inside the mold.

Le renfoncement boxé de préhension 2, produit à l'aide d'un insert de boxage, ne peut pas être obtenu par le seul soufflage d'une préforme sur une forme déterminée d'un moule (par exemple une excroissance faisant saillie vers l'intérieur de la cavité de moulage), et ce notamment vis-à-vis de la profondeur du renfoncement boxé de préhension 2. En effet, tel qu'expliqué précédemment, la profondeur d'un renfoncement boxé est plus importante que la profondeur maximale atteignable par le soufflage d'une préforme sur une forme déterminée d'un moule.The boxed gripping recess 2, produced using a boxing insert, cannot be obtained by simply blowing a preform onto a specific shape of a mold (for example a protrusion projecting towards the interior of the molding cavity), and this in particular with regard to the depth of the boxed gripping recess 2. Indeed, as explained previously, the depth of a boxed recess is greater than the maximum achievable depth by blowing a preform onto a specific shape of a mold.

Selon le principe de l'invention et tel qu'illustré par les figures 3 et 5, le renfoncement boxé de préhension 2 présente une ligne médiane 20 d'enfoncement maximal.According to the principle of the invention and as illustrated by the figures 3 And 5 , the boxed gripping recess 2 has a center line 20 of maximum depression.

Cette ligne médiane 20 d'enfoncement maximal correspond au profil de l'insert de boxage au travers du moule sur la hauteur prédéterminée H, et à l'empreinte que l'insert de boxage laisse sur le récipient 1.This median line 20 of maximum depression corresponds to the profile of the boxing insert through the mold over the predetermined height H, and to the imprint that the boxing insert leaves on the container 1.

Le renfoncement boxé de préhension 2 présente également, tel qu'illustré par la figure 1, une bordure latérale droite 21 ainsi qu'une bordure latérale gauche 22. La bordure latérale droite 21 et la bordure latérale gauche 22 encadrent la ligne médiane 20 d'enfoncement maximal.The boxed gripping recess 2 also has, as illustrated by the figure 1 , a right side border 21 as well as a left side border 22. The right side border 21 and the left side border 22 frame the center line 20 of maximum depression.

Toujours selon le principe de l'invention et en référence aux figures 3 à 6, la ligne médiane 20 d'enfoncement maximal s'inscrit dans un plan diamétral P qui est équidistant de la bordure latérale droite 21 et de la bordure latérale gauche 22.Still according to the principle of the invention and with reference to the figures 3 to 6 , the median line 20 of maximum depression lies in a diametrical plane P which is equidistant from the right side edge 21 and the left side edge 22.

Ce plan diamétral P correspond aux vues des figures 3 et 5, et est représenté sur les figures 4 et 6.This diametrical plane P corresponds to the views of figures 3 And 5 , and is represented on the figures 4 And 6 .

De plus, le renfoncement boxé de préhension 2 est le seul renfoncement boxé sur le corps 10 sur la hauteur prédéterminée H.In addition, the boxed gripping recess 2 is the only boxed recess on the body 10 over the predetermined height H.

C'est-à-dire que sur la hauteur prédéterminée H, le corps 10 ne présente pas d'autre boxage. Le corps 10 peut toutefois présenter d'autres renfoncements qui ne sont pas réalisés par boxage sur la hauteur prédéterminée H.That is to say that on the predetermined height H, the body 10 does not present any other boxing. The body 10 may, however, have other recesses which are not made by boxing to the predetermined height H.

En référence aux figures 4 et 6, le point le plus profond 200 de la ligne médiane 20 d'enfoncement maximal est situé de 5 millimètres à 15 millimètres de l'axe central C du récipient 1 sans que le renfoncement boxé de préhension 2 n'interfère avec l'axe central C.With reference to figures 4 And 6 , the deepest point 200 of the center line 20 of maximum depression is located 5 millimeters to 15 millimeters from the central axis C of the container 1 without the boxed gripping recess 2 interfering with the central axis C .

Selon le présent mode de réalisation, le point le plus profond 200 de la ligne médiane 20 d'enfoncement maximal est situé à une distance D de 7,5 millimètres de l'axe central C.According to the present embodiment, the deepest point 200 of the center line 20 of maximum depression is located at a distance D of 7.5 millimeters from the central axis C.

Tel que cela est illustré par les figures 4 et 6, on comprend que l'insert de boxage, lors de la fabrication de ce récipient 1, est déplacé selon un axe de translation, inscrit dans un plan médian de l'insert, sécant avec l'axe central C du récipient.As illustrated by the figures 4 And 6 , we understand that the boxing insert, during the manufacture of this container 1, is moved along a translation axis, inscribed in a median plane of the insert, intersecting with the central axis C of the container.

De cette manière, le récipient 1 peut être formé par étirage soufflage.In this way, the container 1 can be formed by stretch blow molding.

En effet, lors de sa fabrication, il n'est pas nécessaire qu'une tige d'élongation soit remontée en avance pour permettre le boxage du renfoncement boxé de préhension 2 sur, ou dans, ou au travers, du volume occupé par cette tige d'élongation lorsqu'elle est complètement enfoncée à l'intérieur du récipient 1.Indeed, during its manufacture, it is not necessary for an elongation rod to be raised in advance to allow the boxing of the boxed gripping recess 2 on, or in, or through, the volume occupied by this rod elongation when it is completely inserted inside the container 1.

Tel que cela est illustré par les figures 4 et 6, le corps 10 est symétrique par rapport au plan diamétral P sur la hauteur prédéterminée H.As illustrated by the figures 4 And 6 , the body 10 is symmetrical with respect to the diametrical plane P over the predetermined height H.

Le renfoncement boxé de préhension 2 est détaillé ci-après en référence aux figures 3 à 6.The boxed gripping recess 2 is detailed below with reference to the figures 3 to 6 .

Tel qu'illustré par la figure 4, le renfoncement boxé de préhension 2 présente un angle d'ouverture α.As illustrated by the figure 4 , the boxed gripping recess 2 has an opening angle α.

Plus précisément, le renfoncement boxé de préhension 2 présente de part et d'autre de la ligne médiane 20 d'enfoncement maximal un pan latéral droit 210 et un pan latéral gauche 220.More precisely, the boxed gripping recess 2 has on either side of the center line 20 of maximum depression a right side panel 210 and a left side panel 220.

Le pan latéral droit 210 s'inscrit dans un premier plan L1, et le pan latéral gauche 220 s'inscrit dans un second plan L2.The right side panel 210 fits into a first plane L1, and the left side pan 220 fits into a second plane L2.

Le premier plan L1 et le second plan L2 se croisent selon l'angle d'ouverture α qui est compris entre 25° et 45°, et plus préférentiellement de 30° à 40°. Cet angle d'ouverture α se mesure dans un plan orthogonal à l'axe central C.The first plane L1 and the second plane L2 intersect according to the opening angle α which is between 25° and 45°, and more preferably from 30° to 40°. This opening angle α is measured in a plane orthogonal to the central axis C.

Selon le mode de réalisation illustré par la figure 4, l'angle d'ouverture α est égal à 35°.Selon le mode de réalisation illustré par la figure 6, l'angle d'ouverture α est égal à 37°.According to the embodiment illustrated by Figure 4 , the opening angle α is equal to 35°. According to the embodiment illustrated by Figure 6 , the opening angle α is equal to 37°.

En référence aux figures 2, 4 et 6, le premier plan L1 et le second plan L2 se croisent dans un plan orthogonal à l'axe central C et sur la hauteur prédéterminée H à un point de rencontre 5.With reference to figures 2 , 4 And 6 , the first plane L1 and the second plane L2 intersect in a plane orthogonal to the central axis C and on the predetermined height H at a meeting point 5.

Ce point de rencontre 5 est situé derrière l'axe central C par rapport au renfoncement boxé de préhension 2.This meeting point 5 is located behind the central axis C in relation to the boxed gripping recess 2.

Ce point de rencontre 5 est également situé dans le plan diamétral P.This meeting point 5 is also located in the diametrical plane P.

Tel qu'illustré par les figures 3 et 5, la ligne médiane 20 d'enfoncement maximal est convexe vers l'axe central C, entre une extrémité haute et une extrémité basse éloignées de l'axe central C.As illustrated by the figures 3 And 5 , the median line 20 of maximum depression is convex towards the central axis C, between a high end and a low end distant from the central axis C.

En d'autres termes, la ligne médiane 20 d'enfoncement maximal est incurvée entre ses extrémités haute et basse de manière à ce qu'une partie centrale de cette ligne médiane 20 d'enfoncement maximal soit plus proche de l'axe central C que lesdites extrémités.In other words, the median line 20 of maximum penetration is curved between its upper and lower ends so that a central part of this median line 20 of maximum penetration is closer to the central axis C than said ends.

Tel qu'illustré par le détail de la figure 3, et selon le premier mode de réalisation, la ligne médiane 20 d'enfoncement maximal présente :

  • une première portion 201 ;
  • une seconde portion 202.
As illustrated by the detail of the Figure 3 , and according to the first embodiment, the center line 20 of maximum depression has:
  • a first portion 201;
  • a second portion 202.

La première portion 201 s'étend à partir de l'extrémité haute de la ligne médiane 20 d'enfoncement maximal jusqu'au point le plus profond 200 de la ligne médiane 20 d'enfoncement maximal.The first portion 201 extends from the upper end of the center line 20 of maximum depression to the deepest point 200 of the center line 20 of maximum depression.

La seconde portion 202 s'étend quant à elle depuis la première portion 201, et notamment à partir du point le plus profond 200, jusqu'à l'extrémité basse de la ligne médiane 20 d'enfoncement maximal.The second portion 202 extends from the first portion 201, and in particular from the deepest point 200, to the lower end of the median line 20 of maximum depression.

La première portion 201 présente un rayon de courbure R1, et la seconde portion 202 présente un rayon de courbure R2.The first portion 201 has a radius of curvature R1, and the second portion 202 has a radius of curvature R2.

Tel qu'illustré par la figure 3, le rayon de courbure R1 est inférieur au rayon de courbure R2.As illustrated by the Figure 3 , the radius of curvature R1 is less than the radius of curvature R2.

Cette conception déplace le point le plus profond 200 de la ligne médiane 20 d'enfoncement maximal au-dessus de la mi-hauteur M du renfoncement boxé de préhension 2 c'est-à-dire vers l'ouverture 11 du récipient.This design moves the deepest point 200 of the center line 20 of maximum depression above the mid-height M of the boxed gripping recess 2, that is to say towards the opening 11 of the container.

Tel qu'illustré par le détail de la figure 5, et selon le deuxième mode de réalisation, la ligne médiane 20 d'enfoncement maximal présente :

  • une première portion 201 ;
  • une seconde portion 202 ;
  • une portion intermédiaire 203.
As illustrated by the detail of the Figure 5 , and according to the second embodiment, the center line 20 of maximum depression has:
  • a first portion 201;
  • a second portion 202;
  • an intermediate portion 203.

La première portion 201 s'étend à partir de l'extrémité haute de la ligne médiane 20 d'enfoncement maximal jusqu'au point le plus profond 200 de la ligne médiane 20 d'enfoncement maximal.The first portion 201 extends from the upper end of the center line 20 of maximum depression to the deepest point 200 of the center line 20 of maximum depression.

La portion intermédiaire 203 s'étend depuis la première portion 201, et notamment à partir du point le plus profond 200, jusqu'à un point intermédiaire 204 le long de la ligne médiane 20 d'enfoncement maximal.The intermediate portion 203 extends from the first portion 201, and in particular from the deepest point 200, to an intermediate point 204 along the center line 20 of maximum depression.

La seconde portion 202 s'étend quant à elle depuis la portion intermédiaire 203, et notamment à partir du point intermédiaire 204, jusqu'à l'extrémité basse de la ligne médiane 20 d'enfoncement maximal.The second portion 202 extends from the intermediate portion 203, and in particular from the intermediate point 204, to the lower end of the median line 20 of maximum depression.

La première portion 201 présente un rayon de courbure R1, la seconde portion 202 présente un rayon de courbure R2., et la portion intermédiaire 203 présente un rayon de courbure R3.The first portion 201 has a radius of curvature R1, the second portion 202 has a radius of curvature R2., and the intermediate portion 203 has a radius of curvature R3.

Tel qu'illustré par la figure 5, le rayon de courbure R1 et le rayon de courbure R2 sont tels que la première portion 201 et la seconde portion 202 présentent une courbure significative, et sont ainsi courbées.As illustrated by the figure 5 , the radius of curvature R1 and the radius of curvature R2 are such that the first portion 201 and the second portion 202 have a significant curvature, and are thus curved.

La portion intermédiaire 203 est essentiellement droite. A cet effet, le rayon de courbure R3 est tellement important que la portion intermédiaire 203 peut être assimilée à une droite.The intermediate portion 203 is essentially straight. For this purpose, the radius of curvature R3 is so large that the intermediate portion 203 can be compared to a straight line.

En référence aux figures 1 à 3, le corps 10 présente, sur sa hauteur prédéterminée H et le long de l'axe central C une section transversale, telle que celle représentée sur la figure 4, qui s'inscrit à l'intérieur d'un cercle.With reference to figures 1 to 3 , the body 10 has, over its predetermined height H and along the central axis C, a cross section, such as that shown on the figure 4 , which fits inside a circle.

De préférence, sur la hauteur prédéterminée H, le diamètre du cercle diminue depuis une extrémité haute de la hauteur prédéterminée H, c'est-à-dire vers l'ouverture 11 du récipient 1, puis, après avoir atteint un diamètre minimal prédéterminé, augmente jusqu'à une extrémité basse de la hauteur prédéterminée H, c'est à dire vers le fond 12 du récipient 1.Preferably, over the predetermined height H, the diameter of the circle decreases from a high end of the predetermined height H, that is to say towards the opening 11 of the container 1, then, after having reached a predetermined minimum diameter, increases to a lower end of the predetermined height H, that is to say towards the bottom 12 of the container 1.

En d'autres termes, dans un tel cas de diminution de diamètre, le récipient 1 présente un amincissement sur sa hauteur prédéterminée H.In other words, in such a case of reduction in diameter, the container 1 presents a thinning over its predetermined height H.

Tel qu'illustré par les figures 1, 2, 3 et 5, le corps 10 présente sur sa hauteur prédéterminée H un rétreint de positionnement 3 d'un doigt.As illustrated by the figures 1 , 2 , 3 And 5 , the body 10 has on its predetermined height H a positioning constriction 3 of a finger.

Ce rétreint de positionnement 3 est diamétralement opposé au renfoncement boxé de préhension 2.This positioning constriction 3 is diametrically opposite the boxed gripping recess 2.

Ce rétreint de positionnement 3 est obtenu grâce à la forme de la cavité du moule.This positioning restriction 3 is obtained thanks to the shape of the mold cavity.

Plus précisément, le rétreint de positionnement 3 est obtenu grâce au soufflage du matériau plastique, lors de la réalisation du récipient 1, et ainsi à l'application du matériau plastique contre la surface du moule qui présente une forme complémentaire de celle du récipient 1 illustré par la figure 3.More precisely, the positioning constriction 3 is obtained thanks to the blowing of the plastic material, during the production of the container 1, and thus to the application of the plastic material against the surface of the mold which has a shape complementary to that of the container 1 illustrated over there Figure 3 .

Le rétreint de positionnement 3 est sensiblement lisse.The positioning constriction 3 is substantially smooth.

Comme illustré sur les figures 1, 2, et 3, le corps 10 peut présenter des corrugations annulaires 4 de renfort, réparties régulièrement sur sa hauteur. Ces corrugations annulaires 4 de renfort sont notamment présentes sur la hauteur prédéterminée H.As illustrated on the figures 1 , 2 , And 3 , the body 10 may have annular reinforcement corrugations 4, distributed regularly over its height. These annular reinforcement corrugations 4 are notably present on the predetermined height H.

Tel qu'illustré par les figures 1, 2 et 3, les corrugations annulaires 4 de renfort sur la hauteur prédéterminée H peuvent être configurées de façon que le rétreint de positionnement 3 soit positionné entre deux corrugations annulaires 4 adjacentes.As illustrated by the figures 1 , 2 And 3 , the annular reinforcement corrugations 4 over the predetermined height H can be configured so that the positioning constriction 3 is positioned between two adjacent annular corrugations 4.

En effet, au-dessus du rétreint de positionnement 3, les corrugations annulaires 4 s'étendent depuis le renfoncement boxé de préhension 2 en s'orientant vers le haut, et en dessous du rétreint de positionnement 3, les corrugations annulaires 4 s'étendent depuis le renfoncement boxé de préhension 2 en étant orientées vers le bas.Indeed, above the positioning constriction 3, the annular corrugations 4 extend from the boxed gripping recess 2 oriented upwards, and below the positioning constriction 3, the corrugations annular rings 4 extend from the boxed gripping recess 2 while being oriented downwards.

Les deux corrugations annulaires 4 qui encadrent le rétreint de positionnement 2 s'écartent ainsi l'une de l'autre au niveau du rétreint de positionnement 3.The two annular corrugations 4 which frame the positioning constriction 2 thus deviate from one another at the level of the positioning constriction 3.

En référence à la figure 3, dans le plan diamétral P et selon une projection orthogonale sur l'axe central C, le rétreint de positionnement 3 est situé au-dessus de la mi-hauteur M du renfoncement boxé de préhension 2.In reference to the Figure 3 , in the diametrical plane P and according to an orthogonal projection on the central axis C, the positioning constriction 3 is located above the mid-height M of the boxed gripping recess 2.

Un tel récipient 1 selon l'invention est plus ergonomique lors de la prise en main de la bouteille grâce à la présence du renfoncement boxé de préhension 2 et du rétreint de positionnement 3 d'un doigt.Such a container 1 according to the invention is more ergonomic when holding the bottle thanks to the presence of the boxed gripping recess 2 and the positioning constriction 3 of a finger.

En effet, lors de la saisie du récipient à l'aide d'une main, les doigts de l'utilisateur, à l'exception du pouce, viennent naturellement s'insérer dans le renfoncement boxé de préhension 2. Le pouce de la main est alors orienté vers l'ouverture 11 du récipient. Ainsi, la position du rétreint de positionnement 3, au-dessus de la mi-hauteur M du renfoncement boxé de préhension 2, aide à un positionnement naturel du pouce pour pincer la bouteille.Indeed, when grasping the container using one hand, the user's fingers, with the exception of the thumb, naturally insert themselves into the boxed gripping recess 2. The thumb of the hand is then oriented towards the opening 11 of the container. Thus, the position of the positioning recess 3, above the mid-height M of the boxed gripping recess 2, helps in natural positioning of the thumb for pinching the bottle.

En référence aux figures 4 et 6, le corps 10 présente un premier développé 101 et un second développé 102 de part et d'autre du plan diamétral P du corps 10.With reference to figures 4 And 6 , the body 10 has a first development 101 and a second development 102 on either side of the diametrical plane P of the body 10.

Le premier développé 101 et le second développé 102 correspondent au pourtour du corps 10, dans un plan orthogonal à l'axe central C, entre le point le plus profond 200 et un point 23 diamétralement opposé au point le plus profond 200.The first developed 101 and the second developed 102 correspond to the periphery of the body 10, in a plane orthogonal to the central axis C, between the deepest point 200 and a point 23 diametrically opposite the deepest point 200.

Les longueurs des premier développé 101 et second développé 102 sont chacune comprises entre 100 et 160 millimètres.The lengths of the first developed 101 and second developed 102 are each between 100 and 160 millimeters.

Selon les modes de réalisation illustrés par les figures 4 et 6, le premier développé 101 et le second développé 102 sont égaux étant donné que le corps 10 est symétrique par rapport au plan diamétral P sur la hauteur prédéterminée H.According to the embodiments illustrated by the figures 4 And 6 , the first developed 101 and the second developed 102 are equal given that the body 10 is symmetrical with respect to the diametrical plane P over the predetermined height H.

En référence au premier mode de réalisation illustré par la figure 4, le premier développé 101 et le second développé 102 sont égaux à 126 millimètres.With reference to the first embodiment illustrated by the figure 4 , the first developed 101 and the second developed 102 are equal to 126 millimeters.

En référence au second mode de réalisation illustré par la figure 6, le premier développé 101 et le second développé 102 sont égaux à 140 millimètres.With reference to the second embodiment illustrated by the Figure 6 , the first developed 101 and the second developed 102 are equal to 140 millimeters.

De tels développés de préhension permettent une bonne préhension des récipients par des mains de différentes dimensions.Such grip developments allow good gripping of containers by hands of different sizes.
