Abstract

Container of the type containing a liquid such as a beverage or other fluid substance, comprising a neck (12) retracted into the container before use, and closed by a cap (16) including a gripping element (14), the neck being pulled up ready for use by said gripping element. A membrane (20) which closes the passage between the container and the retracted neck, is integral with the latter and seals the container before use. A membrane-opening means (22) integral with the container walls (18) includes an end which is secured to the inner membrane face. When the gripping member is used to pull up the retracted neck ready for use, at least one portion (20-2) of the membrane is held by the opening means, thereby freeing the passage between the container and the neck for the flow of liquid contents after the container has been opened.

Description

Récipient hermétique à goulot escamotable Hermetic container with retractable neck
Domaine technique :Technical area :
La présente invention concerne les récipients hermétiques et en particulier un récipient du type contenant un liquide ou autre matériau fluide comprenant un goulot escamoté dans le récipient avant utilisation et mis en position d'utilisation par retrait du récipient au moyen d'un élément de préhension.The present invention relates to hermetic containers and in particular a container of the type containing a liquid or other fluent material comprising a neck retracted into the container before use and placed in the position of use by removing the container by means of a gripping element.
Etat de la technique :State of the art:
Il existe actuellement dans le commerce des boîtes métalliques contenant des boissons rafraîchissantes, gazeuses ou non dont 1'ouverture se fait par basculement d'une languette rigide prédécoupée dans le métal de la boîte. Au moment de l'ouverture, la partie de la languette qui provoque l'ouverture de la paroi entre dans le liquide. Or, cette languette a pu être exposée à des poussières, des souillures et autres contaminants qui peuvent introduire des germes pathologiques dans la boisson. En outre, ce type de récipient, une fois ouvert, est difficilement transportable, et par conséquent, oblige à en verser entièrement le contenu après ouverture. Sinon, le liquide qui a pu se répandre sur la partie supérieure du récipient, introduit des germes pathogènes. Lorsqu'il boit directement, l'utilisateur peut en outre mettre ses lèvres en contact avec des endroits souillés et donc contaminés. Enfin, outre que ce type de récipient n'est pas pratique à utiliser pour en boire directement le contenu lorsque 1'on ne dispose pas de verre, son ouverture n'est pas aisée pour les enfants et les personnes âgées, et peut entraîner la projection du liquide contenu, principalement lorsqu'il s'agit de boisson gazeuse. Exposé de 1'invention ;There are currently commercially available metal cans containing refreshing drinks, whether carbonated or not, the opening of which is effected by tilting a rigid tongue precut in the metal of the can. At the time of opening, the part of the tongue that causes the opening of the wall enters the liquid. However, this tab could have been exposed to dust, dirt and other contaminants which can introduce pathological germs into the drink. In addition, this type of container, once opened, is difficult to transport, and therefore requires the entire contents to be poured after opening. Otherwise, the liquid that may have spilled on the upper part of the container introduces pathogenic germs. When drinking directly, the user can also put his lips in contact with soiled and therefore contaminated places. Finally, in addition to the fact that this type of container is not practical to use for directly drinking the contents when there is no glass, its opening is not easy for children and the elderly, and can lead to projection of the liquid contained, mainly when it is a carbonated drink. Statement of the invention;
C'est pourquoi le but principal de l'invention est de réaliser un récipient hermétique du type à goulot escamotable ne présentant pas de risque de contamination du contenu du récipient ou de contact contaminant lorsque 1'on boit ou de projection à 1'extérieur du récipient lors de l'ouverture, et en simplifiant la manoeuvre d'ouverture.This is why the main object of the invention is to produce an airtight container of the retractable neck type which does not present a risk of contamination of the contents of the container or of contaminating contact when drinking or being sprayed outside the container. container during opening, and by simplifying the opening maneuver.
Un autre but de 1'invention est de fournir un récipient hermétique du type à goulot escamotable dont 1'ouverture se fait automatiquement lors de la première utilisation du récipient.Another object of the invention is to provide an airtight container of the retractable neck type, the opening of which is done automatically when the container is first used.
Encore un autre but de 1'invention est de fournir un récipient hermétique du type boîte métallique comportant un goulot escamotable évitant tout risque de projection à 1'extérieur du récipient lors de 1'ouverture.Yet another object of the invention is to provide an airtight container of the metal box type comprising a retractable neck avoiding any risk of projection outside the container during opening.
L'objet de l'invention est donc un récipient du type à goulot escamotable fermé par un bouchon comportant un élément de préhension pour mettre le goulot en position de versement, comprenant un opercule fermant le passage entre le récipient et le goulot en position escamotée, solidaire de ce dernier et rendant le récipient hermétique avant utilisation, un moyen d'ouverture d'opercule rigide, solidaire des parois du récipient et dont une extrémité est fixée à la face intérieure de l'opercule, de sorte que, lorsque 1'élément de préhension est tiré de façon à extraire le goulot escamoté pour le mettre en position d'utilisation, au moins une partie de 1'opercule soit retenue par le moyen d'ouverture d'opercule, ouvrant ainsi le passage entre le récipient et le goulot et permettant 1'écoulement du contenu du récipient après ouverture du bouchon.The object of the invention is therefore a container of the type with a retractable neck closed by a stopper comprising a gripping element for putting the neck in the pouring position, comprising a seal closing the passage between the container and the neck in the retracted position, integral with the latter and making the container hermetic before use, a means of opening a rigid lid, integral with the walls of the container and one end of which is fixed to the inner face of the lid, so that, when the element gripper is pulled so as to extract the retracted neck to put it in the position of use, at least part of the cover is retained by the cover opening means, thus opening the passage between the container and the neck and allowing the flow of the contents of the container after opening the cap.
Un autre objet de 1'invention est un récipient métallique du type contenant un liquide tel qu'une boisson ou autre matériau fluide, comprenant un goulot escamoté dans le récipient avant utilisation, et fermé par un bouchon comportant un élément de préhension, ledit récipient étant formé d'un corps de récipient et d'un couvercle serti sur le corps de récipient, le couvercle comportant une ouverture dans laquelle est placé ledit goulot. Le goulot escamotable est composé d'une portion en forme de collerette en contact avec la partie supérieure du couvercle et située au bord de l'ouverture, d'une portion en forme de ventouse dont la périphérie est en contact hermétique avec la face intérieure du couvercle, et d'une portion de forme cylindrique reliant la portion en forme de collerette et ladite portion en forme de ventouse, de sorte que le bord de 1'ouverture dans le couvercle ne puisse pas entrer en contact avec le contenu du récipient de façon à éviter toute migration d'atomes de métal dans le contenu du récipient.Another object of the invention is a metal container of the type containing a liquid such as a drink or other fluid material, comprising a neck retracted into the container before use, and closed by a stopper comprising a gripping element, said container being formed of a container body and a cover crimped onto the container body, the cover having an opening in which said neck is placed. The retractable neck is composed of a flange-shaped portion in contact with the upper part of the cover and situated at the edge of the opening, of a suction cup-shaped portion whose periphery is in hermetic contact with the inner face of the lid, and a cylindrical portion connecting the flange-shaped portion and said suction cup-shaped portion, so that the edge of the opening in the lid cannot come into contact with the contents of the container avoid any migration of metal atoms into the contents of the container.

Description détaillée :Detailed description :
Le récipient hermétique selon un premier mode de réalisation de 1'invention est avantageusement une boîte du type de celles utilisées pour contenir des boissons gazeuses ou non, jus de fruits, etc. Au lieu du système classique que 1'on trouve actuellement sur ce type de récipient qui est partiellement enfoncé dans la boîte à l'endroit de 1'ouverture préformée lorsque 1'on soulève 1'extrémité d'une languette, le récipient 10 représenté sur la figure 1 dispose d'un goulot escamotable. Le goulot est tiré en position de versement (illustré sur la figure 1) en tirant une anse 14 solidaire d'un bouchon 16 vissé sur le goulot 12.The hermetic container according to a first embodiment of the invention is advantageously a box of the type used to contain carbonated or non-carbonated drinks, fruit juices, etc. Instead of the conventional system which is currently found on this type of container which is partially pressed into the box at the location of the preformed opening when the end of a tongue is lifted, the container 10 shown on Figure 1 has a retractable neck. The neck is pulled into the pouring position (illustrated in FIG. 1) by pulling a handle 14 secured to a plug 16 screwed onto the neck 12.
Lorsque 1'on utilise le récipient 10 pour la première fois, celui-ci est operculé, et ce n'est qu'au moment où 1'on tire le goulot vers 1'extérieur du récipient en se servant de l'anse 14 que l'opercule est retiré. En effet, comme illustré sur la figure 2 représentant une coupe de la partie supérieure 18 du récipient et du goulot en position escamotée, le goulot 12 est fermé dans sa partie inférieure par un opercule 20 qui rend donc le récipient hermétique et empêche le liquide de pouvoir être versé en dehors du récipient.When the container 10 is used for the first time, it is sealed, and it is only when the neck is pulled towards the outside of the container using the handle 14 that the cover is removed. In fact, as illustrated in FIG. 2 showing a section through the upper part 18 of the container and the neck in the retracted position, the neck 12 is closed in its lower part by a cover 20 which therefore makes the container hermetic and prevents the liquid from be able to be poured out of the container.
L'opercule 20 est fixé à une extrémité d'un élément rigide 22 dont 1'autre extrémité est solidaire de la partie supérieure 18 du récipient. On doit noter que l'élément 22, bien que de préférence en forme de potence, pourrait avoir une autre forme et pourrait ne pas être rigide dans la mesure où il opposera une résistance suffisante lors de l'ouverture pour permettre la déchirure de l'opercule. En outre, le point d'attache de l'élément 22 sur la paroi du récipient pourrait se trouver à un autre endroit de la partie supérieure 18 ou sur d'autres parties du récipient que celle illustrée sur la figure 2.The cover 20 is fixed to one end of a rigid element 22, the other end of which is integral with the part upper 18 of the container. It should be noted that the element 22, although preferably in the form of a gallows, could have another shape and may not be rigid in so far as it will provide sufficient resistance during opening to allow tearing of the operculum. In addition, the point of attachment of the element 22 on the wall of the container could be located elsewhere in the upper part 18 or on other parts of the container than that illustrated in FIG. 2.
L'opercule 20 comporte une zone de moindre résistance représentée en coupe sur la figure 2, par les deux rétrécissements 24. La zone de moindre résistance est sous forme d'une courbe fermée, et de préférence circulaire puisque le goulot est généralement circulaire.The cover 20 has a zone of least resistance shown in section in FIG. 2, by the two narrowing 24. The zone of least resistance is in the form of a closed curve, and preferably circular since the neck is generally circular.
Lorsque 1'on désire ouvrir le récipient pour en verser le contenu, on tire sur l'anse 14. Le goulot étant tiré vers le haut et 1'opercule étant retenu vers le bas par 1'élément rigide 22, l'opercule 20 se déchire le long de la zone de moindre résistance illustrée par les rétrécissements 24 de la figure 2.When one wishes to open the container to pour the contents, one pulls on the handle 14. The neck being pulled upwards and the cover being retained downwards by the rigid element 22, the cover 20 is tears along the zone of least resistance illustrated by the narrowing 24 of FIG. 2.
Le goulot 12, entraînant la jupe 26 peut donc être mis en position de versement. Comme représenté sur la figure 3, l'opercule est alors séparé en deux parties, une partie 20-1 restée solidaire du goulot 12, et une partie 20-2 restée fixée sur 1'élément rigide 22.The neck 12, driving the skirt 26 can therefore be put into the pouring position. As shown in FIG. 3, the cover is then separated into two parts, a part 20-1 which remains integral with the neck 12, and a part 20-2 which remains fixed on the rigid element 22.
Comme illustré sur la figure 2, la fixation de 1'opercule sur 1'élément rigide 22 se trouve à proximité immédiate du rétrécissement 24 marquant la zone de moindre résistance où se déchirera l'opercule. Cette proximité du point de rétrécissement par rapport à 1'extrémité de 1'élément rigide 22 permet 1'application d'une force de cisaillement importante lorsque l'on exerce une force en tirant 1'anse 14 de façon à mettre le goulot 12 en position de versement, et par conséquent un démarrage facilité de la déchirure de 1'opercule.As illustrated in FIG. 2, the fixing of the cover to the rigid element 22 is in the immediate vicinity of the narrowing 24 marking the zone of least resistance where the cover will tear. This proximity of the point of narrowing relative to the end of the rigid element 22 allows the application of a large shear force when a force is exerted by pulling the handle 14 so as to put the neck 12 in pouring position, and consequently easier starting of the tearing of the cover.
Le récipient selon le premier mode de réalisation de 1'invention peut être assemblé en plusieurs pièces, par exemple en fabriquant 1'ensemble formé par la paroi supérieure ou une partie de la paroi supérieure, la jupe, l'opercule, l'élément rigide et le goulot dans une seule pièce en matière plastique, et en fixant cet ensemble sur les parois 18 du récipient (ou la partie de la paroi supérieure solidaire du récipient) qui peut être en métal comme le sont les boîtes de boisson classiques. Cependant, il est préférable que le récipient soit fabriqué en une seule pièce en matière plastique obtenue par moulage (c'est la réalisation illustrée sur les igures 2 et 3). Que le récipient soit en une seule pièce ou en plusieurs, la jupe 26 doit impérativement être en matière souple de façon à être dépliée pour passer de la position où le goulot est escamoté à la position où il est opérationnel pour verser le contenu du récipient.The container according to the first embodiment of the invention can be assembled in several pieces, by example by manufacturing the assembly formed by the upper wall or a part of the upper wall, the skirt, the cover, the rigid element and the neck in a single plastic part, and by fixing this assembly on the walls 18 of the container (or the part of the upper wall integral with the container) which may be made of metal as are conventional drink cans. However, it is preferable that the container is made in a single piece of plastic material obtained by molding (this is the embodiment illustrated in FIGS. 2 and 3). Whether the container is in one piece or in several, the skirt 26 must imperatively be made of flexible material so as to be unfolded to pass from the position where the neck is retracted to the position where it is operational for pouring the contents of the container.
Un second mode de réalisation d'un récipient répondant aux objectifs de la présente invention est décrit en référence aux figures 4 et 5.A second embodiment of a container meeting the objectives of the present invention is described with reference to Figures 4 and 5.
Comme il a été mentionné ci-dessus, les boites métalliques du commerce contenant des boissons rafraîchissantes ont l'inconvénient que l'ouverture par enfoncement d'une languette peut introduire des souillures ou autres contaminants dans le liquide contenu dans la boite. C'est pourquoi l'idée des demandeurs est d'utiliser un dispositif de goulot escamotable adapté sur une boite métallique.As mentioned above, the commercial cans containing refreshing drinks have the disadvantage that the opening by depressing a tab can introduce stains or other contaminants into the liquid contained in the box. This is why the applicants' idea is to use a retractable neck device adapted to a metal box.
Une boite métallique est formée d'un corps de récipient 30 de forme généralement cylindrique sur lequel est serti un couvercle 32 comportant une ouverture circulaire de préférence décentrée (pour faciliter le versement du contenu du récipient) dans laquelle est installé le goulot escamotable 34. Comme dans le mode de réalisation précédent, lorsqu'on utilise le récipient pour la première fois, le goulot escamotable 34 est tiré vers 1'extérieur du récipient en se servant d'une anse (non représentée sur la figure). Le goulot 34 entraîne alors la jupe 36 en position de versement comme illustré sur la figure 5. On doit noter que dans ce mode de réalisation, l'étanchéité du récipient n'est plus assurée par un opercule, mais directement par le bouchon.A metal box is formed of a container body 30 of generally cylindrical shape on which is crimped a cover 32 having a circular opening preferably off-center (to facilitate the pouring of the contents of the container) in which is installed the retractable neck 34. As in the previous embodiment, when the container is used for the first time, the retractable neck 34 is pulled towards the outside of the container using a handle (not shown in the figure). The neck 34 then drives the skirt 36 into the pouring position as illustrated in the Figure 5. It should be noted that in this embodiment, the sealing of the container is no longer ensured by a cover, but directly by the cap.
Le goulot escamotable est fixé dans le couvercle 32 préalablement à la fermeture du récipient de la manière illustrée sur la figure 4. Du fait que le goulot escamotable, fabriqué en une seule pièce, est en matière plastique, il est enfoncé en force dans le couvercle de bas en haut, l'introduction de la portion en forme de collerette 38 étant facilitée par son bord chanfreine.The retractable neck is fixed in the cover 32 before closing the container as illustrated in FIG. 4. Because the retractable neck, made in one piece, is made of plastic, it is forced into the cover from bottom to top, the introduction of the collar-shaped portion 38 being facilitated by its chamfered edge.
Le goulot 34 comporte, outre la portion en forme de collerette 38 à bord chanfreine, une portion en forme de ventouse 40. Tant que le goulot 34 n'a pas été placé dans le couvercle 32, le bord extérieur de la ventouse 40 est plus élevé que la collerette 38 (voir figure 4). Lorsque le goulot 34 est inséré en force dans 1'ouverture du couvercle 32, la collerette 38 se positionne au dessus du bord de l'ouverture du couvercle tandis que la base 46 de la ventouse 40 bute contre un rebord circulaire 48 du couvercle. La portion cylindrique 44 du goulot située entre la collerette 38 et la base de la ventouse 46 emprisonne une portion cylindrique 42 du goulot. Quand le goulot se met en place dans l'ouverture, la ventouse retenue par la face intérieure du couvercle tend à s'écarter en exerçant une force à sa périphérie contre le couvercle et assure ainsi une parfaite étanchéité.The neck 34 includes, in addition to the collar-shaped portion 38 with a chamfered edge, a suction cup-shaped portion 40. As long as the neck 34 has not been placed in the cover 32, the outer edge of the suction cup 40 is more higher than the flange 38 (see Figure 4). When the neck 34 is forcibly inserted into the opening of the cover 32, the flange 38 is positioned above the edge of the opening of the cover while the base 46 of the suction cup 40 abuts against a circular rim 48 of the cover. The cylindrical portion 44 of the neck located between the flange 38 and the base of the suction cup 46 traps a cylindrical portion 42 of the neck. When the neck is placed in the opening, the suction cup retained by the inner face of the cover tends to move apart, exerting a force at its periphery against the cover and thus ensures a perfect seal.
Le contenu d'une boite métallique à laquelle s'applique l'invention est souvent une boisson gazeuse, entraînant une pression sous le couvercle qui peut atteindre plusieurs bars. Par conséquent, à cause de cette pression, la portion en forme de ventouse 40 a tendance à exercer une force plus importante contre le couvercle 32, son bord restant étroitement plaqué contre ledit couvercle. Toutefois, la partie 46 la plus basse de la portion en forme de ventouse, plate, est retenue par le rebord circulaire 48. Du fait de cette pression qui maintient la portion en forme de ventouse 40 plaquée contre le couvercle 32, le liquide ne peut pénétrer entre le couvercle et la portion en forme de ventouse et atteindre le rebord 48 de 1'ouverture du couvercle. Ceci est une caractéristique importante de ce mode de réalisation dans la mesure où, l'ensemble des parois de la boite métallique et son couvercle ayant été protégés par un vernis, seule la tranche du rebord 48 du couvercle présente du métal sans protection, et donc un contact entre le rebord 48 du couvercle et le liquide pourrait entraîner une migration des atomes de métal de la boite dans le liquide.The content of a metal can to which the invention applies is often a carbonated drink, causing pressure under the lid which can reach several bars. Consequently, because of this pressure, the suction cup-shaped portion 40 tends to exert a greater force against the cover 32, its edge remaining tightly pressed against said cover. However, the lowest part 46 of the flat suction cup portion is retained by the circular rim 48. Because of this pressure which keeps the suction cup portion 40 pressed against the cover 32, the liquid does not can penetrate between the cover and the suction cup portion and reach the flange 48 of the opening of the cover. This is an important characteristic of this embodiment insofar as, all the walls of the metal box and its cover having been protected by a varnish, only the edge of the rim 48 of the cover has metal without protection, and therefore contact between the rim 48 of the cover and the liquid could cause the metal atoms of the box to migrate into the liquid.
Un bouchon 16 pouvant être utilisé aussi bien pour le mode de réalisation représenté sur les figures 1, 2, 3 que pour le mode de réalisation illustré sur les figures 4 et 5, est représenté sur la figure 6. Sur cette figure, la jupe 26 (ou 36) et le goulot 12 (ou 34) sont en position escamotée. Le bouchon 16 est vissé sur l'extrémité supérieure du goulot 12 (ou 34) au moyen d'un filetage (non représenté). Il est à noter que le bouchon pourrait être également enfoncé par pression en utilisant une fermeture du type "clip".A plug 16 which can be used both for the embodiment shown in Figures 1, 2, 3 as for the embodiment illustrated in Figures 4 and 5, is shown in Figure 6. In this figure, the skirt 26 (or 36) and the neck 12 (or 34) are in the retracted position. The plug 16 is screwed onto the upper end of the neck 12 (or 34) by means of a thread (not shown). It should be noted that the plug could also be pressed in using a "clip" type closure.
Comme on le voit sur la figure 6, le bouchon 16 comporte une languette 50, qui peut être moulée en même temps que le bouchon à la fabrication. A la mise en place du bouchon 16 (et de la languette) sur le goulot 12 (ou 34), la languette est introduite dans un passant 52. L'extrémité de la languette 50 se termine par un harpon 54 prolongé par un élément d'ancrage 56 relié au harpon 54 par une portion amincie. Lorsque la languette est en place, l'élément d'ancrage 56 est fixé à la paroi du récipient par collage ou tout autre moyen équivalent.As can be seen in FIG. 6, the plug 16 has a tongue 50, which can be molded at the same time as the plug during manufacture. When the plug 16 (and the tongue) is placed on the neck 12 (or 34), the tongue is introduced into a loop 52. The end of the tongue 50 ends in a harpoon 54 extended by an element d anchor 56 connected to the harpoon 54 by a thinned portion. When the tongue is in place, the anchoring element 56 is fixed to the wall of the container by gluing or any other equivalent means.
Lors de la première utilisation du récipient, on saisit la languette en passant un doigt dessous, dans l'évidement du bouchon 16. Du fait que l'élément 56 fixé au récipient est relié au harpon 54 par une portion de moindre résistance, la languette se désolidarise facilement de l'élément 56. La languette prend alors la forme d'une anse comme illustré sur la figure 7. La partie arrière 55 du harpon 54 est alors retenue par le passant 52. On a donc bien une anse qui permet, en continuant à exercer une force de traction, de sortir l'ensemble de la jupe 26 (ou 36) et du goulot 12 (ou 34) muni de son bouchon 16.When the container is used for the first time, the tongue is grasped by passing a finger below it, in the recess of the cap 16. Because the element 56 fixed to the container is connected to the harpoon 54 by a portion of lesser resistance, the tongue is easily detached from the element 56. The tongue then takes the form of a handle as illustrated in FIG. 7. The rear part 55 of the harpoon 54 is then retained by the loop 52. We therefore have indeed a handle which allows, while continuing to exert a tensile force, to remove the assembly of the skirt 26 (or 36) and the neck 12 (or 34) provided with its plug 16.
Bien que la languette soit de préférence réalisée conformément à la représentation donnée dans les figures 6 et 7, il est possible de réaliser une languette disposant d'un harpon à chaque extrémité, le bouchon comportant alors deux passants dans lesquels on enfile chaque extrémité de la languette au moment du montage.Although the tongue is preferably produced in accordance with the representation given in FIGS. 6 and 7, it is possible to produce a tongue having a harpoon at each end, the plug then comprising two loops in which each end of the tongue when mounting.
Bien que sur les figures illustrant 1'invention le goulot escamotable représenté ait les dimensions d'un goulot de bouteille, il peut avoir un diamètre différent. Ainsi, le goulot escamotable peut avoir un diamètre correspondant à celui d'un verre, ce qui permet de boire aisément le contenu du récipient selon 1'invention lorsque 1'on n'a pas de verre à sa disposition.Although in the figures illustrating the invention the retractable neck shown has the dimensions of a bottle neck, it may have a different diameter. Thus, the retractable neck can have a diameter corresponding to that of a glass, which makes it easy to drink the contents of the container according to the invention when there is no glass at its disposal.
Le récipient selon 1'invention est utilisé de préférence pour contenir du liquide tel qu'une boisson ou autre, mais peut également être utilisé pour contenir un matériau fluide tel que de la poudre, des granules...The container according to the invention is preferably used to contain liquid such as a drink or the like, but can also be used to contain a fluid material such as powder, granules, etc.
Contrairement aux boîtes contenant de la boisson de la technique antérieure, le récipient selon l'invention est hygiénique en ce qu'il n'y a pas enfoncement d'une partie pouvant être souillée dans le liquide lors de l'ouverture. Contrairement aux boites à boisson classiques, il n'y a pas danger que le liquide se répande sur la partie supérieure du récipient et introduise des germes pathogènes. Lorsqu'il boit, l'utilisateur ne risque pas de poser ses lèvres à des endroits souillés. En outre, il est possible d'escamoter à nouveau le goulot après fermeture par le bouchon lorsque le contenu du récipient n'est pas versé en une seule fois, sans s'exposer à des risques de contamination par des souillures, poussières ou autres comme c'est le cas des boîtes de 1'art antérieur, et ainsi de transporter le récipient sans problème. Unlike cans containing drinks of the prior art, the container according to the invention is hygienic in that there is no depression of a part which can be soiled in the liquid during opening. Unlike conventional beverage cans, there is no danger that the liquid will spill over the top of the container and introduce pathogenic germs. When drinking, the user is not likely to put his lips in soiled places. In addition, it is possible to retract the neck again after closing with the cap when the contents of the container are not poured in one go, without exposing oneself to the risk of contamination by dirt, dust or the like. this is the case of the boxes of the prior art, and thus of transporting the container without problem.
