Description
L'invention concerne un flacon de distribution d'un produit fluide, notamment d'un gel ou d'une crème, par exemple d'un produit cosmétique ou d'un produit pharmaceutique.The invention relates to a dispensing bottle of a fluid product, in particular a gel or a cream, for example a cosmetic product or a pharmaceutical product.
En particulier, les flacons selon l'invention trouvent leur utilisation pour distribuer des échantillons de produit, notamment en volume compris entre 1 et 10 ml.In particular, the bottles according to the invention find their use for dispensing product samples, especially in volume of between 1 and 10 ml.
On connaît des flacons équipés d'un système de distribution comprenant un soufflet en matériau élastiquement déformable qui est monté sur le corps dudit flacon pour être en communication avec le produit. En outre, le système de distribution comprend un clapet d'admission et un clapet d'échappement du produit qui sont agencés pour, par compression manuelle du soufflet, mettre le produit sous pression en vue de sa distribution par l'intermédiaire d'un orifice et, par relâchement de ladite compression, doser le produit à distribuer dans ledit soufflet. Ainsi, le système de distribution forme une pompe à actionnement manuel de structure particulièrement simple.Bottles equipped with a dispensing system comprising a bellows of elastically deformable material which is mounted on the body of said bottle to be in communication with the product are known. In addition, the dispensing system comprises an intake valve and a product exhaust valve which are arranged to manually press the bellows to pressurize the product for dispensing through an orifice. and, by releasing said compression, dosing the product to be dispensed into said bellows. Thus, the dispensing system forms a manually operated pump of particularly simple structure.
Toutefois, un problème qui se pose avec de tels flacons de distribution concerne la fermeture de l'orifice de distribution entre deux distributions. En effet, une telle fermeture doit être réalisée pour, d'une part empêcher les fuites de produit dosé dans le soufflet et d'autre part, limiter les contacts entre l'air extérieur et ledit produit, notamment pour éviter un desséchement et/ou une dégradation dudit produit dans le temps.However, a problem with such dispensing bottles is the closure of the dispensing orifice between two dispensations. Indeed, such a closure must be performed to, on the one hand prevent leakage of the product metered into the bellows and on the other hand, limit the contact between the outside air and said product, in particular to prevent drying out and / or degradation of said product over time.

En outre, toujours pour améliorer cette fonction d'échappement, l'extrémité libre 27 de la membrane 26 comprend un bourrelet de contact 27a avec le soufflet 4. Comme représenté sur la
Par ailleurs, la cheminée 20 représentée comprend une portée supérieure 20a qui s'étend axialement au dessus de l'extrémité libre 27 de la membrane 26. Ainsi, la portée 20a permet une reprise des efforts du soufflet 4 en fin de course de compression, de sorte à éviter un possible endommagement de la membrane 26.Moreover, the
Le flacon comprend en outre un capot rigide 28 qui est destiné à recouvrir le soufflet 4 en position de repos entre les distributions, ledit capot en position de recouvrement étant agencé pour entourer la base 5, au moins sur une hauteur supérieure à celle de sa partie supérieure 5b. Pour ce faire, le capot 28 comprend une paroi supérieure 28a qui est entourée par une jupe 28b dont la partie inférieure est disposée autour de la base 5. Sur les figures, le capot est agencé pour que la jupe 28b recouvre toute la partie supérieure 5b et une partie de la partie inférieure 5a.The bottle further comprises a
Pour assurer la fermeture de l'orifice de distribution 24 entre deux utilisations, ledit orifice est entouré extérieurement par un bec saillant 29 et l'interférence entre la jupe 28b et la base 5 est suffisante pour que ladite jupe vienne en appui étanche sur le bec 29. En particulier, le capot 28 étant rigide et le bec 29 étant réalisé avec le soufflet 4 en matériau élastiquement déformable, l'interférence peut induire une déformation élastique dudit bec de sorte à procurer une étanchéité renforcée lors de la fermeture.To ensure the closure of the dispensing
Sur les figures, le bec 29 entoure toute la périphérie de l'orifice de distribution 24 en présentant une géométrie ovale centré sur ledit orifice, l'épaisseur dudit bec décroissant régulièrement depuis le centre vers l'extérieur.In the figures, the
Lors de la disposition du capot 28 en position de recouvrement, le bord de la jupe 28b prend appui sur le bec 29 pour le déformer lors du coulissement de ladite jupe sur lui, ladite contrainte de déformation est maintenue tant que le capot 28 demeure en position de recouvrement. En outre, cette déformation assure le verrouillage du capot 28 en position de recouvrement.When the
Par ailleurs, la surface extérieure de la base 5, et notamment celle de sa partie supérieure 5b, comprend des bossages 30 de centrage et de verrouillage du capot 28 en position de recouvrement. Sur les figures, deux bossages 30 sont prévues à 120° de part et d'autre de l'orifice 24 et dans un même plan radial, lesdits bossages ayant une épaisseur équivalente à celle du bec 29 de sorte à assurer le centrage.Furthermore, the outer surface of the
En relation avec les
Pour réaliser le serrage radial, le diamètre de la portée supérieure 3a de la bague 3 est inférieur à celui de sa portée inférieure 3b de sorte à former un logement annulaire entre ladite portée supérieure et l'extrémité 1a du corps 1, la partie inférieure 5a de la base 5 étant serrée dans ledit logement. En particulier, la différence de diamètres entre les portées 3a, 3b peut être légèrement inférieure à l'épaisseur de la partie inférieure 5a, de sorte à mettre ladite partie en compression dans ledit logement.To achieve the radial clamping, the diameter of the
Ainsi, après l'accrochage de la partie inférieure 5a sur la portée supérieure 3a et le remplissage du récipient 2 en produit, la bague 3 est emmanchée dans le corps 1 pour réaliser le serrage. En outre, le serrage permet de fiabiliser l'action des moyens d'accrochage de la base 5 sur la portée supérieure 3a réalisés par les rainures 25.Thus, after the attachment of the
Par ailleurs, la base 5 est pourvue d'un bourrelet 31 qui s'étend extérieurement, le capot 28 en position de recouvrement venant en appui axial sur ledit bourrelet. Ainsi, le bourrelet 31 forme butée de fin de course de recouvrement du capot 28, en assurant un amortissement du fait de son caractère élastiquement déformable.Furthermore, the
