Abstract

The present invention relates to a stopper having a sleeve with pouring lip for bottles and like receptacles with necks. Inside the sleeve is provided a transverse disc supported on spaced apart arms join to a perforated annular partition supporting the sleeve. When the liquid is poured out, it is guided between the periphery of the disc and the sleeve, at the same time that air is inducted through the upper openings of the perforated zone. The invention finds particular application in the stoppering industry.

Description

La présente invention a trait aux bouchons verseurs destinés à être fixés sur le goulot des bouteilles, flacons et autres récipients analogues, en vue d'assurer le bouchage de ceux-ci tout en facilitant le déversement du contenu.The present invention relates to pouring caps intended to be fixed on the neck of bottles, flasks and other similar containers, with a view to ensuring their closure while facilitating the pouring of the contents.

On sait que dans leur forme classique les bouchons de ce type comprennent généralement un corps agencé de façon à être retenu de manière étanche sur l'extrémité ouverte du goulot, et un capuchon amovible propre à obturer l'ouverture du corps précité. Ce dernier est ordinairement solidaire d'un manchon cylindrique qui vient recouvrir ou prolonger le sommet de la paroi interne du goulot et qui dépasse en avant de celle-ci pour s'épanouir radialement vers l'extérieur et former ainsi bec verseur. A ce bec verseur sont associés des moyens internes (cloison, croisillon, disque transversal, perforations, etc ...) destinés à guider le liquide lors de son déversement et à favoriser l'entrée de l'air à l'intérieur du récipient.It is known that in their conventional form, plugs of this type generally comprise a body arranged so as to be retained in leaktight manner on the open end of the neck, and a removable cap capable of closing the opening of the abovementioned body. The latter is usually integral with a cylindrical sleeve which covers or extends the top of the internal wall of the neck and which protrudes in front of the latter to open out radially outwards and thus form a pouring spout. With this pouring spout are associated internal means (partition, spider, transverse disc, perforations, etc.) intended to guide the liquid during its spillage and to favor the entry of air inside the container.

Les perfectionnements qui font l'objet de la présente invention ont plus spécialement pour but de permettre la réalisation d'un bouchon verseur du genre susvisé qui présente un fonctionnement particulièrement satisfaisant tout en restant de fabrication simple et économique.The improvements which are the subject of the present invention are more specifically intended to allow the production of a pouring plug of the aforementioned type which has a particularly satisfactory operation while remaining simple and economical to manufacture.

Le bouchon verseur suivant l'invention, du genre comprenant un corps propre à se fixer sur le goulot du récipient et pourvu d'un bec verseur formé par un manchon cylindrique qui renferme, avec un jeu annulaire propre à laisser passage au liquide, un disque transversal relié par des bras substantiellement verticaux à la partie inférieure du bec ou manchon précité, est caractérisé en ce que les bras se raccordent à la partie inférieure par une zone annulaire ajourée orientée obliquement de haut en bas en direction de l'axe dudit bec en faisant ainsi saillie à l'intérieur de la base de ce dernier, de façon à déterminer une sorte de barrière pour le liquide lors de l'écoulement tout en permettant l'entrée de l'air à l'intérieur du récipient.The pouring plug according to the invention, of the kind comprising a body capable of being fixed on the neck of the container and provided with a pouring spout formed by a cylindrical sleeve which encloses, with an annular clearance suitable for letting the liquid pass, a disc transverse connected by substantially vertical arms to the lower part of the aforementioned spout or sleeve, is characterized in that the arms are connected to the lower part by a perforated annular zone oriented obliquely from top to bottom in the direction of the axis of said spout thus projecting inside the base of the latter, so as to determine a kind of barrier for the liquid during the flow while allowing the entry of air inside the container.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention:

  • La figure unique de ce dessin montre en coupe axiale schématique l'agencement général d'un bouchon verseur suivant l'invention, avec en superposition le capuchon de fermeture et le goulot de la bouteille correspondante.
The appended drawing, given by way of example, will allow a better understanding of the invention:
  • The single figure of this drawing shows in schematic axial section the general arrangement of a pouring cap according to the invention, with the closure cap and the neck of the corresponding bottle superimposed.

A la façon en soi connue le bouchon représenté comprend un corps principal 1 établi en une matière synthétique souple conformée par moulage, et un capuchon de fermeture 2 réalisé en une matière plastique rigide. Le corps 1 est destiné à venir se fixer sur la partie supérieure ouverte du goulot 3 d'une bouteille.In the manner known per se, the stopper shown comprises a main body 1 made of a flexible synthetic material shaped by molding, and a closure cap 2 made of a rigid plastic material. The body 1 is intended to be fixed on the open upper part of the neck 3 of a bottle.

Le corps 1 comporte un manchon cylindrique 10 disposé axialement et pourvu à son sommet d'un rebord 10a évasé vers l'extérieur, de façon à former bec verseur. La base de ce manchon ou bec 10 se raccorde par une cloison annulaire 11, orientée obliquement de haut en bas en direction de l'extérieur, à un étrier annulaire 12 propre à chevaucher le bord supérieur du goulot 3 en venant s'encliqueter élastiquement dans une gorge 30 de celui-ci. A l'étrier 12 est en outre associée une bande déchirable de garantie 13, agencée de façon à retenir la base 20 du capuchon 2 en garantissant ainsi le contenu de la bouteille jusqu'au moment de la première utilisation. Le fond transversal de ce capuchon 2 est solidaire d'une cheminée axiale 21 destinée à venir s'engager de manière étanche dans le bec 10.The body 1 comprises a cylindrical sleeve 10 disposed axially and provided at its top with a rim 10a flared outwards, so as to form a spout. The base of this sleeve or spout 10 is connected by an annular partition 11, oriented obliquely from top to bottom in the direction of the outside, to an annular stirrup 12 suitable for overlapping the upper edge of the neck 3 by snap-fitting in a groove 30 thereof. The stirrup 12 is also associated with a tear-off guarantee strip 13, arranged so as to retain the base 20 of the cap 2, thereby guaranteeing the contents of the bottle until the time of first use. The transverse bottom of this cap 2 is integral with an axial chimney 21 intended to engage sealingly in the spout 10.

La base du bec verseur 10 se raccorde, à l'opposé de la cloison 11 susmentionnée, à une zone annulaire ajourée 14, orientée obliquement de haut en bas en direction de l'intérieur. Le bord inférieur des ouvertures de cette zone 14 est formé par un anneau 15, solidaire de trois bras 16 tournés vers le haut et qui convergent en direction de la face inférieure d'un disque 17 dont ils sont solidaires par moulage. Le disque 17, établi à un profil circulaire dans l'exemple de réalisation considéré, présente un diamètre inférieur au diamètre intérieur du bec 10.The base of the pouring spout 10 is connected, opposite the aforementioned partition 11, to an openwork annular zone 14, oriented obliquely from top to bottom in the direction of the interior. The lower edge of the openings in this zone 14 is formed by a ring 15, integral with three arms 16 turned upwards and which converge towards the underside of a disc 17 of which they are integral by molding. The disc 17, established with a circular profile in the embodiment considered, has a diameter less than the inside diameter of the spout 10.

Il convient de noter que l'ensemble du bouchon est susceptible d'être facilement obtenu par moulage en une seule pièce, la matière étant injectée à partir du disque transversal 17.It should be noted that the entire plug can be easily obtained by molding in one piece, the material being injected from the transverse disc 17.

Le fonctionnement du bec verseur ci-dessus décrit découle des explications qui précèdent et se conçoit aisément.The operation of the spout described above follows from the foregoing explanations and is easy to understand.

Lorsque la bouteille est inclinée vers le bas pour le déversement du contenu après élimination de la bande 13 et retrait du capuchon 2, le liquide, canalisé par la cloison oblique 11, se heurte à la zone ajourée 14 qu'il ne traverse pratiquement pas; ce liquide passe par dessus l'anneau inférieur 15 et, guidé par les bras convergents 16, est obligé de s'étaler dans l'espace annulaire compris entre le pourtour du disque 17 et la paroi interne du bec 10. Les essais et les études ont démontré que le liquide occupait alors une section correspondant à une portion de couronne, ce qui facilite l'écoulement et favorise par ailleurs l'entrée de l'air dans la bouteille à travers une ou plusieurs des ouvertures de la zone ajourée 14 qui sont tournées vers le haut lors du déversement.When the bottle is tilted downward for the discharge of the contents after elimination of the strip 13 and removal of the cap 2, the liquid, channeled by the oblique partition 11, collides with the perforated zone 14 which it practically does not pass through; this liquid passes over the lower ring 15 and, guided by the converging arms 16, is forced to spread in the annular space comprised between the periphery of the disc 17 and the internal wall of the spout 10. Tests and studies have shown that the liquid then occupied a section corresponding to a portion of the crown, which facilitates the flow and also promotes the entry of air into the bottle through one or more of the openings in the perforated zone 14 which are turned upward during the spill.

On obtient de la sorte un débit régulier de liquide et une entrée d'air par une succession ininterrompue de petites bulles, et ce quelle que soit la hauteur occupée par le liquide dans le bouteille; l'écoulement ne donne lieu à aucune saccade. On notera que le cheminement des bulles d'air est favorisé par le profil oblique de la zone annulaire 14, laquelle détermine une série de crénaux formant guides.This gives a regular flow of liquid and an air intake by an uninterrupted succession of small bubbles, regardless of the height occupied by the liquid in the bottle; the flow does not give rise to any jerking. Note that the path of the air bubbles is favored by the oblique profile of the annular zone 14, which determines a series of crenals forming guides.

Le nombre et le profil des ouvertures pratiquées dans la zone annulaire ajourée 14 peuvent être quelconques; il en va de même pour les bras de liaison 16 qui peuvent en certains cas être profilés pour déterminer une sorte d'hélice. Le disque 17 est susceptible de présenter un profil elliptique lorsqu'on veut obtenir momentanément un débit d'écoulement réduit moyennant une orientation particulière de la bouteille ou autre récipient.The number and the profile of the openings made in the perforated annular zone 14 can be any; the same goes for the link arms 16 which can in some cases be profiled to determine a kind of propeller. The disc 17 is likely to have an elliptical profile when it is desired to temporarily obtain a reduced flow rate by means of a particular orientation of the bottle or other container.

On notera en outre que l'invention peut être avantageusement mise en oeuvre pour la réalisation de bouchons verseurs à bec coulissant, du type de ceux employés notamment en combinaison avec les bidons d'huiles minérales et similaires.It will also be noted that the invention can be advantageously implemented for the production of pouring plugs with sliding spout, of the type of those used in particular in combination with cans of mineral oils and the like.
