Description

Dispositif pour conditionner et distribuer des lentilles cornéennes..  Device for packaging and dispensing contact lenses ..
La présente invention se rapporte à un dispositif formant emballage de lentilles de contact, notamment des dispositifs d'emballage de lentilles de contact ou cornéennes, la lentille, comme l'emballage, étant destinée à être jetée après . utilisation . The present invention relates to a device for packaging contact lenses, in particular contact lens packaging devices or contact lenses, the lens, such as the packaging, being intended to be discarded afterwards . use .
La présente invention se rapporte également à un assemblage constitué d'un emballage de ce genre et d'au moins une. lentille emballée en son sein. The present invention also relates to an assembly consisting of a packaging of this kind and at least one. lens packed within it.
L'emballage ou le conditionnement des lentilles de contact ou cornéennes, notamment des lentilles destinées à n'être utilisées que de manière temporaire, notamment une seule journée, et à être jetées ensuite, est classiquement effectué dans des étuis jetables qui comportent un opercule, classiquement en aluminium, que l'on ouvre par pelage et l'utilisateur devant tremper son doigt dans un fluide de conditionnement, usuellement un liquide de conditionnement, afin d'y trouver, de manière hasardeuse, la lentille au fond de l'étui. L'opération consistant à récupérer la lentille dans son emballage est particulièrement compliquée. En outre, cette opération n'est pas facilitée par le fait que l'utilisateur, du fait même de porter des lentilles, n'a pas une vue que l'on peut qualifier de parfaite. The packaging or conditioning of the contact lenses or contact lenses, including lenses intended to be used only temporarily, especially a single day, and to be thrown away, is conventionally carried out in disposable cases that include a cover, conventionally made of aluminum, which is peeled open and the user having to dip his finger in a conditioning fluid, usually a conditioning liquid, to find, in a hazardous manner, the lens at the bottom of the case. The operation of recovering the lens in its packaging is particularly complicated. In addition, this operation is not facilitated by the fact that the user, by the very fact of wearing lenses, does not have a view that can be described as perfect.
La présente invention vise à surmonter les inconvénients des emballages ou étuis de l'art antérieur en proposant un emballage ou étui pour lentilles de contact qui permet à l'utilisateur de récupérer la lentille de l'emballage d'une manière particulièrement simple et rapide. The present invention aims to overcome the disadvantages of packaging or cases of the prior art by providing a package or case for contact lenses that allows the user to recover the lens of the package in a particularly simple and fast manner.
Suivant l'invention, un emballage ou étui est tel que défini à la revendication 1. On obtient ainsi un étui pour emballer une lentille, notamment une lentille jetable, qui est particulièrement simple d'utilisation. Lorsque l'utilisateur ouvre l'étui, la lentille apparaît directement accessible, sans liquide interposé entre elle et le ou les doigt (s), ce qui évite les opérations salissantes et en même temps elle est bien supportée vers le haut et donc facile à accéder par un ou des doigt (s). Dans le même temps, elle est parfaitement conditionnée lorsque l'étui est fermé en étant conservée dans du liquide de conditionnement, le liquide de conditionnement étant évacué avant l'ouverture, notamment par l'intermédiaire d'un opercule. L'utilisation est donc particulièrement simple. According to the invention, a package or case is as defined in claim 1. A case is thus obtained for packaging a lens, in particular a disposable lens, which is particularly easy to use. When the user opens the case, the lens appears directly accessible without liquid interposed between it and the finger (s), which avoids messy operations and at the same time it is well supported upwards and therefore easy to access by finger (s). At the same time, it is perfectly packaged when the case is closed while being stored in conditioning liquid, the conditioning liquid being evacuated before opening, in particular by means of a lid. The use is therefore particularly simple.
Des perfectionnements et modes de réalisation avantageux sont définis aux sous-revendications. Advantages and advantageous embodiments are defined in the subclaims.
La présente invention se rapporte également à un assemblage comportant un étui suivant l'invention et au moins une lentille de contact emballée dans l'étui et du liquide de conditionnement emplissant l'enceinte définie par l'étui. The present invention also relates to an assembly comprising a case according to the invention and at least one contact lens packaged in the case and the conditioning liquid filling the enclosure defined by the case.

Aux figures 1 à 7, il est représenté un premier mode de réalisation de l'invention. L'étui 1 suivant l'invention est constitué de trois parties, à savoir un élément 2 inférieur de base, un élément 3 supérieur formant couvercle entre lesquels est prise en sandwich la lentille 4 emballée par l'étui 1 et une troisième partie constituée par un opercule 5. L'élément 2 inférieur formant base est constitué d'une plaque 6 mince de base, par exemple de forme sensiblement rectangulaire, percée d'un trou 13 entouré par un élément 7 en forme de dôme intérieur ou inférieur. En outre, une tirette 8 en forme de patte fait saillie sensiblement verticalement de la plaque 6 pour permettre sa prise entre le pouce et 1' index . In Figures 1 to 7, there is shown a first embodiment of the invention. The case 1 according to the invention consists of three parts, namely a lower base element 2, an upper element 3 forming a cover between which is sandwiched the lens 4 packaged by the case 1 and a third part constituted by 5. The lower base element 2 consists of a thin base plate 6, for example of substantially rectangular shape, pierced with a hole 13 surrounded by an element 7 in the form of an inner or lower dome. In addition, a pull tab 8 in the form of a tab protrudes substantially vertically from the plate 6 to allow its grip between the thumb and 1 index.
La surface du dôme 7 est percée de trous traversant, notamment en étant sous la forme d'une grille ou d'une passoire, pour permettre le passage facile d'un liquide de conditionnement à travers elle. En outre de préférence, la surface couverte par les parties vides de la passoire formant le dôme 7 sont supérieures aux parties pleines pour assurer une fixation « par capillarité » la meilleure possible de la lentille 4 sur le dôme 7. The surface of the dome 7 is pierced with through holes, in particular being in the form of a grid or a colander, to allow easy passage of a conditioning liquid therethrough. Further preferably, the surface covered by the empty portions of the dome-forming strainer 7 are larger than the solid parts to provide the best possible "capillary" attachment of the lens 4 to the dome 7.
L'élément 3 supérieur formant couvercle de l'étui 1 est constitué d'une plaque 9 mince supérieure, par exemple sensiblement rectangulaire, comportant un trou 11 entouré par une coque 10 extérieure ou supérieure sensiblement de forme hémisphérique, de préférence transparente et qui a des dimensions appropriées pour entourer complètement le dôme 7 inférieur avec la lentille 4 (qui est très mince) lorsque les deux plaques 6 et 9 sont en contact l'une contre l'autre, comme on le voit bien par exemple à la figure 2. Une tirette 12 sous la forme d'une patte fait saillie également verticalement sensiblement dans la même direction que la patte 8, les deux pattes 8 et 12 étant décalées l'une par rapport à l'autre lorsque les deux plaques 6 et 9 sont disposées en contact l'une avec l'autre pour ainsi se trouver en continuité l'une de 1 ' autre . The upper element 3 forming a lid of the case 1 consists of a thin plate 9, for example a substantially rectangular one, having a hole 11 surrounded by an outer or upper shell 10 which is substantially hemispherical in shape, preferably transparent and which has appropriate dimensions to completely surround the lower dome 7 with the lens 4 (which is very thin) when the two plates 6 and 9 are in contact with each other, as can be seen for example in Figure 2. A pull tab 12 in the form of a tab also protrudes vertically substantially in the same direction as the tab 8, the two tabs 8 and 12 being offset with respect to one another when the two plates 6 and 9 are arranged. in contact with each other so as to be in continuity with one another.
Les deux éléments inférieur et supérieur 2 et 3 définissent une enceinte 40, définie entre la coque 10 et le trou 13 de la plaque 6, dans laquelle sont reçus le dôme 7, la lentille 4 et du liquide de conditionnement. Un opercule 5, notamment sous la forme d'un film métallique tel qu'un aluminium, est collé ou soudé de manière classique à la face inférieure de la partie 2 inférieure pour boucher le trou 13 et ainsi fermer l'enceinte 40. The two lower and upper elements 2 and 3 define an enclosure 40, defined between the shell 10 and the hole 13 of the plate 6, in which are received the dome 7, the lens 4 and conditioning liquid. A lid 5, in particular in the form of a film metal such as aluminum, is bonded or welded in a conventional manner to the underside of the lower portion 2 to plug the hole 13 and thus close the enclosure 40.
La surface du dôme 7 est disposée dans l'enceinte de manière à séparer l'enceinte 40 en deux zones, une zone inférieure sous le dôme 7, entre le dôme 7 et l'ouverture 13 et une zone supérieure, au dessus du dôme 7, entre le dôme .7 et le dôme 10. Du liquide de conditionnement emplit les deux zones de l'enceinte 40, en pouvant passer d'une zone à l'autre par les trous traversant du dôme 7. The surface of the dome 7 is disposed in the enclosure so as to separate the enclosure 40 into two zones, a lower zone under the dome 7, between the dome 7 and the opening 13 and an upper zone, above the dome 7 between the dome 7 and the dome 10. Conditioning liquid fills the two zones of the enclosure 40, being able to pass from one zone to another through the through-holes of the dome 7.
A l'état fermé de l'étui représenté par exemple à la figure 1, le dôme 7 est reçu dans le dôme 10 en prenant en sandwich entre eux la lentille 4 qui repose sur le dôme 7 en forme de treillis, de grille ou de passoire. Les deux pattes 8 et 12 sont côte à côte et du liquide de conditionnement se trouve dans l'enceinte définie par les deux parties 2 et 3 respectivement inférieure et supérieure, c'est-à-dire à l'intérieur de la coque 10. L'opercule 5 bouche le trou 13 pour maintenir le liquide de conditionnement dans l'enceinte 40. In the closed state of the case shown for example in Figure 1, the dome 7 is received in the dome 10 by sandwiching between them the lens 4 which rests on the dome 7 in the form of lattice, grid or strainer. The two lugs 8 and 12 are side by side and the conditioning liquid is in the enclosure defined by the two parts 2 and 3 respectively lower and upper, that is to say inside the shell 10. The cap 5 blocks the hole 13 to maintain the conditioning liquid in the chamber 40.
Une rainure 14 circulaire est formée dans la face inférieure de la plaque 9 de la partie 3 supérieure en étant disposée sensiblement au niveau du bord du dôme 10. Cette rainure 14 coopère avec une nervure 15 circulaire associée faisant saillie de la face supérieure de la plaque 6 de la partie 2 inférieure. Notamment la nervure, en matériau élastique ou élastomère pénètre à adaptation serrée ou à force dans la rainure 14 pour assurer une fermeture étanche de l'enceinte 40. Les deux parties inférieure et supérieure peuvent pivoter l'une par rapport à l'autre par rapport à un axe vertical, la rainure glissant le long de la nervure. Lors de ce glissement, les deux tirettes 8 et 12 s'éloignent l'une de l'autre, donnant à l'utilisateur un effet de levier suffisant pour pouvoir séparer dans la direction verticale la partie supérieure de la partie inférieure par une sorte de rotation par rapport à un axe transversal pour ainsi avoir accès à l'intérieur de 1 ' enceinte . A circular groove 14 is formed in the lower face of the plate 9 of the upper portion 3 being disposed substantially at the edge of the dome 10. This groove 14 cooperates with an associated circular rib 15 projecting from the upper face of the plate 6 of the lower part 2. In particular, the rib, made of elastic or elastomeric material, penetrates tightly or forcefully into the groove 14 to ensure a tight closure of the enclosure 40. The two lower and upper parts can pivot relative to one another relative to each other. to a vertical axis the groove sliding along the rib. During this sliding, the two drawbars 8 and 12 move away from each other, giving the user sufficient leverage to be able to separate in the vertical direction the upper part of the lower part by a kind of rotation relative to a transverse axis so as to have access to the interior of 1 enclosure.
Comme représenté aux figures 4 à 7, le procédé pour retirer la lentille par l'utilisateur est le suivant. Comme représenté à la figure 4, l'utilisateur commence par retirer l'opercule 5 du reste de l'étui, notamment en le tirant par pelage. Il en résulte que le liquide emprisonné dans l'enceinte définie par les deux parties respectivement 2 et 3 inférieure et supérieure et l'opercule 5, à savoir sensiblement l'intérieur de la coque 10, est évacué par le trou 13 de sorte que le liquide et la lentille sont sortis de leur contact mutuel et séparés l'un de l'autre. L'utilisateur ensuite fait pivoter par rapport à un axe V vertical la partie supérieure par rapport à la partie inférieure en éloignant la tirette 12 de la tirette 8, puis réalise un pivot par rapport à un axe transversal à l'axe V pour faire sortir la nervure 15 de la rainure 14 qui maintiennent ensemble les deux parties respectivement inférieure et supérieure, de sorte que la partie 3 supérieure peut être détachée de la partie 2 inférieure, laissant alors apparaître le dôme 7 inférieur avec sur sa face supérieure la lentille 4 disponible pour être prise par un ou plusieurs doigts de l'utilisateur par effet d'adhérence, la lentille étant encore humidifiée par le liquide de conditionnement qui vient juste d'être évacué par le dessous par le trou 13. La lentille se présente à l'utilisateur par son côté convexe. Il en résulte que la prise de la lentille 4 dans une position prête à être insérer dans l'œil est très facile pour l'utilisateur. On se retrouve alors dans la position de la figure 7 dans laquelle on voit en outre que le dôme 7 inférieur comporte également une rainure 16 circulaire à mi-hauteur contre laquelle repose le bord de la lentille 4 lorsque celle-ci est convenablement posée sur le dôme. On s'assure ainsi que la lentille 4 est parfaitement positionnée de manière symétrique sur le dôme 7 pendant son conditionnement dans l'étui et lors de sa présentation à l'utilisateur. As shown in Figures 4 to 7, the method for removing the lens by the user is as follows. As shown in Figure 4, the user begins by removing the lid 5 of the rest of the case, including pulling by peeling. As a result, the liquid trapped in the enclosure defined by the two parts 2 and 3 respectively lower and upper and the cap 5, namely substantially the inside of the shell 10, is discharged through the hole 13 so that the liquid and the lens came out of their mutual contact and separated from each other. The user then rotates with respect to a vertical axis V the upper part relative to the lower part by moving the pull tab 12 of the pull tab 8, then realizes a pivot relative to an axis transverse to the axis V to pull out the rib 15 of the groove 14 which together hold the two parts respectively lower and upper, so that the upper part 3 can be detached from the lower part 2, then leaving the lower dome 7 with on its upper face the lens 4 available to be taken by one or more fingers of the user by adhesion effect, the lens being further moistened by the conditioning liquid which has just been discharged from below by the hole 13. The lens is presented to the user by its convex side. As a result, taking the lens 4 in a position ready to be inserted into the eye is very easy for the user. We then find ourselves in the position of FIG. 7, in which we also see that the lower dome 7 also has a circular groove 16 at mid-height against which the edge of the lens 4 rests when it is properly placed on the dome. This ensures that the lens 4 is perfectly positioned symmetrically on the dome 7 during its packaging in the case and during its presentation to the user.
Dans ce qui suit, des références numériques identiques sont utilisées pour représentés des éléments qui peuvent être de forme légèrement différente mais qui ont la même fonction que dans le mode de réalisation des figures 1 à 7 décrit ci dessus. In the following, like reference numerals are used to represent elements which may be of slightly different shape but have the same function as in the embodiment of Figures 1 to 7 described above.
Aux figures 8, 8A, 8B et 8C, il est représenté un autre mode de réalisation d'un emballage suivant l'invention, In FIGS. 8, 8A, 8B and 8C, there is shown another embodiment of a package according to the invention,
La différence principale entre le mode de réalisation de la figure 8 et celui des figures. 1 à 7 consiste d'une part en la forme du dôme 7 inférieur et d' autre part de la liaison par encliquetage entre les éléments 2 et 3 inférieur et supérieur. The main difference between the embodiment of Figure 8 and that of the figures. 1 to 7 consists on the one hand in the shape of the lower dome 7 and on the other hand the snap connection between the lower and upper elements 2 and 3.
Le dôme 7 est constitué de plusieurs barrettes 20 incurvées et espacées de manière régulière les unes des autres angulairement . Elles partent chacune d'un bord supérieur d'une collerette 21 circulaire faisant saillie de la face supérieure de la plaque 9 de l'élément 2 inférieur et disposée autour du trou 13. Les barrettes 20 incurvées se rejoignent en un sommet et forment ainsi une surface supérieure virtuelle de support en forme de dôme, que l'on appelle pour simplifier le dôme 7 inférieur définissant une surface de support pour la lentille 4. The dome 7 consists of several bars 20 curved and spaced regularly from each other angularly. They each depart from an upper edge of a circular collar 21 projecting from the upper face of the plate 9 of the lower element 2 and arranged around the hole 13. The curved bars 20 meet at a vertex and thus form a virtual top surface of domed support, which is called to simplify the lower dome 7 defining a support surface for the lens 4.
La coque 10 de l'élément 3 supérieur recouvre le dôme 7 inférieur avec interposition entre eux de la lentille 4. L'élément 3 supérieur fait ainsi office de couvercle et son retrait de l'élément 2 de base laisse apparaître la lentille prête à être prise. La liaison entre les deux éléments 2 et 3 inférieur et supérieur assurant la fermeture étanche de l'enceinte est réalisée par encliquetage . Une rainure 22 circulaire est formée dans la face latérale 23 de la collerette 21. dans le même temps, une patte 24 en forme de collerette circulaire fait saillie de la face intérieure de la coque 10 de l'élément supérieur. L'extrémité de la patte 24 circulaire comporte une nervure 25 circulaire qui vient s'ajuster de manière élastique dans la rainure circulaire 22 pour ainsi assurer la fermeture étanche de l'enceinte 40 recevant le liquide de conditionnement et la lentille. Une élasticité appropriée de la patte 24 permet à l'utilisateur de séparer les deux éléments inférieur de base et supérieur formant couvercle pour avoir accès à la lentille. Un opercule 5 bouche le trou 13 de l'enceinte 40. The shell 10 of the upper element 3 covers the lower dome 7 with the interposition of the lens 4 between them. The upper element 3 thus acts as a cover and its removal from the base element 2 reveals the lens ready to be seen. outlet. The connection between the two lower and upper elements 2 and 3 ensuring the tight closure of the enclosure is achieved by snapping. A circular groove 22 is formed in the side face 23 of the flange 21. At the same time, a flange 24 in the form of a circular flange protrudes from the inner face of the shell 10 of the upper element. The end of the circular lug 24 has a circular rib 25 which is resiliently fitted in the circular groove 22 to thereby seal the enclosure 40 receiving the conditioning liquid and the lens. A suitable elasticity of the tab 24 allows the user to separate the two lower base and upper lid members to access the lens. A cover 5 plugs the hole 13 of the enclosure 40.
Aux figures 9, 9A, 9B et 9C, il est représenté un autre mode de réalisation d'un emballage suivant l'invention. In Figures 9, 9A, 9B and 9C, there is shown another embodiment of a package according to the invention.
Dans ce mode de réalisation, il y a toujours deux éléments inférieur 2 de base et supérieur 3 formant couvercle, mais il n'y a plus d'opercule pour former les moyens de séparation du liquide d'avec la lentille. In this embodiment, there are always two lower base and top 3 forming lid members, but there is no longer a lid for forming the liquid separating means from the lens.
L'agencement de l'emballage est réalisé de sorte que la simple séparation des deux éléments 2 et 3 de base et de couvercle réalise les deux fonctions essentielles à l'invention que sont d'une part de séparer le liquide de conditionnement de la lentille et d'autre part de donner l'accès à la lentille par son côté convexe. The arrangement of the packaging is made so that the simple separation of the two elements 2 and 3 of base and lid performs the two functions essential to the invention is on the one hand to separate the conditioning liquid from the lens and on the other hand to give access to the lens by its convex side.
A l'état fermé de l'emballage, la coque 10 du couvercle définit avec la plaque 6 de l'élément 2 de base 2 une enceinte 40 dans laquelle est reçu le liquide de conditionnement, la lentille 4 et un dôme 7 de support. Le dôme 7 est constitué de plaques 41 en forme de quarts de disque répartis de manière uniforme angulairement , par exemple tous les 30°, de manière à former une surface de support en forme de dôme de support. Une collerette 42 de forme circulaire entoure les plaques 41 jusqu' à une certaine hauteur. Cette collerette 42 inférieure coopère avec une collerette 43 supérieure issue de la face intérieure de la coque 10. La collerette 43 supérieure porte de manière élastique contre la collerette 42 inférieure de manière à rendre étanche l'enceinte 40 définie entre elles, la coque 10 et la plaque 6 de la partie 2 de base. In the closed state of the package, the shell 10 of the lid defines with the plate 6 of the element 2 base 2 an enclosure 40 in which is received the conditioning liquid, the lens 4 and a dome 7 support. The dome 7 consists of quarter-disk-shaped plates 41 distributed in an angularly uniform manner, for example every 30 °, so as to form a supporting dome-shaped support surface. A flange 42 of circular shape surrounds the plates 41 to a certain height. This lower flange 42 cooperates with an upper flange 43 coming from the inner face of the shell 10. The upper flange 43 bears elastically against the flange 42 below so as to seal the enclosure 40 defined between them, the shell 10 and the plate 6 of the basic part 2.
Lorsque les deux éléments 2 et 3 de base et de couvercle sont réunis comme représenté aux figures, l'enceinte 40 est remplie de liquide de conditionnement et la lentille baigne dans le liquide. Lorsque l'on retire le couvercle en tirant l'élément 3 de couvercle vers le haut, le liquide s'écoule vers le bas et tombe dans une rigole 50 formée à la face supérieure de la plaque 6 de l'élément 2 de base, notamment entre la collerette 42 inférieure et une collerette 45 concentrique à distance de celle ci. Le liquide est ainsi séparé de la lentille par l'ouverture du couvercle. Dans, le même temps, la lentille apparaît accessible à l'utilisateur par son côté convexe, supportée par le dôme 7 virtuel constitué par les bords supérieurs des quarts de disque et la surface virtuelle entre eux. When the two base and lid elements 2 and 3 are joined as shown in the figures, the enclosure 40 is filled with conditioning liquid and the lens is immersed in the liquid. When the lid is removed by pulling the lid member 3 upwards, the liquid flows downwards and falls into a channel 50 formed on the upper face of the plate 6 of the basic element 2, in particular between the lower flange 42 and a flange 45 concentric away from it. The liquid is thus separated from the lens by the opening of the lid. In the same time, the lens appears accessible to the user by its convex side, supported by the virtual dome 7 constituted by the edges upper quarter discs and the virtual surface between them.
La liaison entre l'élément 2 de base et l'élément 3 de couvercle est réalisée par coopération de nervures 46The connection between the base member 2 and the cover member 3 is made by ribs 46
(par exemple 4 nervures à la figure), qui s'étendent sur un arc de cercle (par exemple 20°) en faisant saillie chacune du bord supérieur de la collerette 45 du côté opposé à l'enceinte 40 et qui sont réparties de préférence de manière uniforme sur le pourtour du bord de la collerette 45, avec des nervures 47 formées à la paroi intérieure de la coque 10 pour réaliser une fermeture de la liaison par encliquetage et son ouverture par une rotation mutuelle de par exemple un quart de tour(for example 4 ribs in the figure), which extend over an arc (for example 20 °) projecting each of the upper edge of the flange 45 on the side opposite the chamber 40 and which are preferably distributed in a uniform manner around the edge of the flange 45, with ribs 47 formed in the inner wall of the shell 10 to close the snap-fastening connection and its opening by mutual rotation of for example a quarter turn
(par exemple par l'intermédiaire des deux pattes 8 et 12 pour faire sortir les nervures 46 et 47 de leur coopération mutuelle et permettre ainsi le détachement du couvercle de la partie de base. (For example through the two legs 8 and 12 to get the ribs 46 and 47 of their mutual cooperation and thus allow the detachment of the lid of the base portion.
Aux figures 10, 10A, 10B et 10C, il est représenté encore un autre mode de réalisation d'un emballage suivant 1' invention. In Figures 10, 10A, 10B and 10C, there is shown yet another embodiment of a package according to the invention.
Il comporte un élément 2 inférieur de base comportant une plaque 6 sensiblement rectangulaire de la face supérieure de laquelle fait saillie d'une part une patte 8 de préhension et d'autre part une collerette 60 sensiblement circulaire qui définit en son sein une enceinte 40. Dans l'enceinte 40 est reçu un élément en forme de dôme 7 percé d'un réseau de trous à la manière d'une passoire, l'enceinte 40 recevant du liquide à la fois au dessus et en dessous de l'élément passoire jusqu'au bord supérieur de la collerette 60. la lentille 4 est posée sur le dôme 7. L'enceinte 40 est fermé par un opercule 61 faisant office de couvercle, l'opercule étant fixé par collage, adhésif, soudure ou analogue. It comprises a lower base element 2 comprising a substantially rectangular plate 6 of the upper face of which protrudes on the one hand a gripping tab 8 and on the other hand a substantially circular collar 60 which defines an enclosure 40 therein. In the enclosure 40 is received a domed element 7 pierced with a network of holes in the manner of a colander, the enclosure 40 receiving liquid both above and below the colander element until at the upper edge of the collar 60. the lens 4 is placed on the dome 7. The chamber 40 is closed by a lid 61 acting as a lid, the lid being fixed by gluing, adhesive, welding or the like.
En outre, la partie de la plaque 6 formant le fond de l'enceinte 40 est percé d'un trou 13 central et de trous latéraux 62. Ce trou central et ces trous latéraux sont bouchés par un opercule 5, fixé par collage, adhésif, soudure ou analogue. In addition, the portion of the plate 6 forming the bottom of the enclosure 40 is pierced with a central hole 13 and lateral holes 62. This central hole and these lateral holes are plugged by a cover 5, fixed by gluing, adhesive , welding or the like.
Pour ouvrir la lentille, l'utilisateur retire -par pelage l'opercule 5 pour ainsi permettre l'évacuation par le dessous du liquide de conditionnement et donc la séparation mutuelle du liquide et de la lentille, puis il retire par pelage le couvercle constitué par l'opercule 61 pour avoir accès à la lentille par son côté convexe, facile à prendre et à poser dans l' il. To open the lens, the user removes the lid 5 by peeling so as to allow the evacuation from below of the conditioning liquid and thus the mutual separation of the liquid and the lens, and then peels off the lid constituted by the operculum 61 to have access to the lens by its convex side, easy to take and put in the eye.
Il peut être prévu dans la paroi latérale extérieure de la collerette 60 une zone de renfoncement 65 pour faciliter la prise de l'opercule 61 qui dépasse de la collerette au niveau de ce renfoncement 65. It can be provided in the outer side wall of the flange 60 a recess area 65 to facilitate the engagement of the lid 61 which protrudes from the collar at this recess 65.
Aux figures 11, 11A, 11B et 11C, il est représenté encore un autre mode de réalisation d'un emballage suivant 1' invention . In Figures 11, 11A, 11B and 11C, there is shown yet another embodiment of a package according to the invention.
Ce mode de réalisation est très proche de celui de la figure 10, la différence résultant principalement dans la forme de l'élément formant le dôme 7 à travers lequel du liquide peut passer et son agencement dans l'enceinte 40. This embodiment is very close to that of FIG. 10, the difference resulting mainly in the shape of the element forming the dome 7 through which liquid can pass and its arrangement in the enclosure 40.
Le dôme 7 est constitué de barrettes 70 incurvées qui s'étendent à partir du fond de l'enceinte 40 pour se rejoindre en un sommet et former avec les surfaces virtuelles intermédiaires une surface de support en forme de dôme 7 sur laquelle repose la lentille 4. Lorsque l'emballage est fermé, la lentille est reçue dans l'enceinte 40, ainsi que du liquide de conditionnement, en dessous et au dessus des barrettes 70. The dome 7 consists of curved bars 70 which extend from the bottom of the enclosure 40 to join at a vertex and form with the intermediate virtual surfaces a dome-shaped support surface 7 on which the lens 4 rests . When the package is closed, the lens is received in the enclosure 40, as well as the conditioning liquid, below and above the bars 70.
Aux figures 12, 12A, 12B et 12C, il est représenté encore un autre mode de réalisation de l'invention. In Figures 12, 12A, 12B and 12C, there is shown yet another embodiment of the invention.
L'emballage comporte un élément 2 inférieur de base (l'emballage est représenté à l'envers aux figures 12, 12A et 12B) . l'élément 2 de base comporte une plaque 6 de base rectangulaire de laquelle fait saillie une coque 80 qui définit entre la plaque 6 et elle même une enceinte 40 dans laquelle sont reçus le liquide de conditionnement et la lentille 4. Le fond de la coque 80 est percé de trous 81. The package has a bottom base member 2 (the package is shown upside down in Figures 12, 12A and 12B). the basic element 2 comprises a rectangular base plate 6 from which protrudes a shell 80 which defines between the plate 6 and itself an enclosure 40 in which are received the conditioning liquid and the lens 4. The bottom of the hull 80 is pierced with holes 81.
Dans le fond de la coque, il est en outre monté des quarts 82 de disque sensiblement identiques à ceux représentés aux figures 9 pour former le dôme 7 de support de lentille. Bien évidemment, à la place des quarts de disque ou pourrait réaliser le dôme 7 avec l'élément passoire de la figure 10, les barrettes de la figure 11 ou tout autre élément analogue constituant une surface de support en forme de dôme à travers laquelle du liquide peut passer. In the bottom of the shell, it is further mounted quarter disc 82 substantially identical to those shown in Figures 9 to form the lens support dome 7. Of course, instead of quarter discs or could realize the dome 7 with the strainer element of Figure 10, the bars of Figure 11 or any other similar element constituting a dome-shaped support surface through which the liquid can pass.
Lorsque l'emballage est fermé, la lentille 4 est reçue dans l'enceinte 40, posée sur le dôme 7 et l'enceinte 40 est emplie de liquide de conditionnement, au dessus et en dessous de la lentille. When the package is closed, the lens 4 is received in the enclosure 40, placed on the dome 7 and the enclosure 40 is filled with conditioning liquid, above and below the lens.
Pour prendre la lentille, l'utilisateur retire par pelage l'opercule 5 fixé par collage, adhésif, soudure ou analogue de la face inférieure de l'élément 2 de base, de sorte que le liquide s'échappe par les trous 81 (pour ce faire, il est préférable d'ailleurs de retirer une petite partie de l'opercule 83 également pour aider à l'évacuation du liquide. Une fois le liquide évacué, la lentille a donc été séparée du liquide et l'utilisateur retire complètement l'opercule 83 qui bouche le trou 13 formé dans la plaque 6 en dessous de la coque 80, de sorte qu' il a accès alors à la lentille par son côté convexe, posée sur le dôme 7 et facile à prendre et à poser dans l'oeil. In order to take the lens, the user removes the operculum 5 by gluing, adhesive, solder or the like from the underside of the base member 2, so that the liquid escapes through the holes 81 (for doing this, it is better besides to remove a small part of the lid 83 also to assist in the evacuation of the liquid. Once the liquid has been discharged, the lens has thus been separated from the liquid and the user completely removes the cap 83 which plugs the hole 13 formed in the plate 6 below the shell 80, so that it then has access to the lens by its convex side, placed on the dome 7 and easy to take and put in the eye.
Aux figures 13, 13A, 13B, 13C et 13D, il est représenté encore un autre mode de réalisation de l'invention. In Figures 13, 13A, 13B, 13C and 13D, there is shown yet another embodiment of the invention.
L'emballage comporte un élément 2 inférieur de base. L'élément 2 de base comporte une plaque 6 de base rectangulaire de laquelle fait saillie une collerette 90 qui définit avec la plaque 6 une enceinte 40 dans laquelle sont reçus le liquide de conditionnement et la lentille 4. La plaque 6 est percée de trous 91. The package comprises a basic lower element 2. The basic element 2 comprises a rectangular base plate 6 from which protrudes a flange 90 which defines with the plate 6 an enclosure 40 in which are received the conditioning liquid and the lens 4. The plate 6 is pierced with holes 91 .
Dans le fond de l'enceinte 40 définie par la plaque 6 et la collerette 90, il est en outre monté des quarts 92 de disque sensiblement identiques à ceux représentés aux figures 9 ou 12 pour former le dôme 7 de support de lentille. Bien évidemment, à la place des quarts de disque ou pourrait réaliser le dôme 7 avec l'élément passoire de la figure 10, les barrettes de la figure 11 ou tout autre élément analogue constituant une surface de support en forme de dôme à travers laquelle du liquide peut passer. In the bottom of the enclosure 40 defined by the plate 6 and the flange 90, it is further mounted quarter disc 92 substantially identical to those shown in Figures 9 or 12 to form the dome 7 lens support. Of course, instead of quarter discs or could realize the dome 7 with the strainer element of Figure 10, the bars of Figure 11 or any other similar element constituting a dome-shaped support surface through which the liquid can pass.
Lorsque l'emballage est fermé, la lentille 4 est reçue dans l'enceinte 40, posée sur le dôme 7 et l'enceinte 40 est emplie de liquide de conditionnement, au dessus et en dessous de la lentille. Pour prendre la lentille, l'utilisateur retire par pelage l'opercule 5 fixé par collage, adhésif, soudure ou analogue de la face inférieure de l'élément 2 de base, de sorte que le liquide s'échappe par les trous 91. Pour ce faire, il est préférable d'ailleurs de retirer une petite partie de l'opercule 93 également pour aider à l'évacuation du liquide. Une fois le liquide évacué, la lentille a donc été séparée du liquide et l'utilisateur retire complètement l'opercule 93 formant couvercle qui ferme l'enceinte 40 par le dessus, de sorte qu'il a alors accès à la lentille par son côté convexe, posée sur le dôme 7 et facile à prendre et à poser dans l'œil. When the package is closed, the lens 4 is received in the enclosure 40, placed on the dome 7 and the enclosure 40 is filled with conditioning liquid, above and below the lens. To take the lens, the user removes by peeling the seal 5 fixed by gluing, adhesive, solder or the like of the lower face of the base element 2, so that the liquid escapes through the holes 91. In doing so, it is preferable, moreover, to remove a small portion of the cap 93 also to assist in the evacuation of the liquid. Once the liquid has been evacuated, the lens has thus been separated from the liquid and the user completely removes the cover cap 93 which closes the enclosure 40 from above, so that it then has access to the lens by its side. convex, placed on the dome 7 and easy to take and put in the eye.
La collerette 90 a une forme sensiblement circulaire, mais bien évidemment pourrait avoir tout autre forme. Ici, on y a prévu en outre un renfoncement pour aider au retrait des opercules 5 et 93 qui font saillie au dessus du renfoncement . The flange 90 has a substantially circular shape, but of course could have any other shape. Here, there is further provided a recess to assist in the removal of the caps 5 and 93 which protrude above the recess.
Aux figures 14, 14A, 14B et 14C, il est représenté encore un autre mode de réalisation de l'invention. In Figures 14, 14A, 14B and 14C, there is shown yet another embodiment of the invention.
L'emballage comporte un élément 2 inférieur de base qui comporte une plaque 6 de base de laquelle font saillie deux collerettes 100 et 101 qui définissent avec la plaque 6 deux enceintes 40L et 40G dans lesquelles sont reçus le liquide de conditionnement et deux lentilles 4L et 4G, respectivement pour l'œil gauche et l'œil droit. The package comprises a lower base element 2 which comprises a base plate 6 from which project two flanges 100 and 101 which define with the plate 6 two enclosures 40L and 40G in which are received the conditioning liquid and two lenses 4L and 4G, respectively for the left eye and the right eye.
Les deux collerettes comporte un filetage respectif extérieur avec lequel coopère un taraudage respectif d'un élément formant couvercle 104 respectif pour fermer les enceintes 40L et 40G par vissage. The two flanges comprise a respective external thread with which cooperates a respective tapping of a respective cover member 104 to close the 40L and 40G enclosures by screwing.
Dans le fond des enceintes 40 il est disposé en succession deux ressorts 103 respectifs et deux éléments 7 formant dôme sur lesquels reposent les lentilles 4L et 4G. In the bottom of the speakers 40, two respective springs 103 and two elements are arranged in succession. 7 forming dome on which the lenses 4L and 4G rest.
Lorsque l'emballage est fermé, les lentilles 4 sont reçues dans leur enceinte 40L ou 40G respective, posée chacune sur un dôme 7 respectif et les enceintes 40 sont emplie de liquide de conditionnement, au dessus et en dessous de la lentille, les ressorts étant comprimés. When the package is closed, the lenses 4 are received in their respective enclosure 40L or 40G, each placed on a respective dome 7 and the enclosures 40 are filled with conditioning liquid, above and below the lens, the springs being tablets.
Pour prendre la lentille, l'utilisateur dévisse le couvercle 104 respectif de l'élément de base, de sorte que les ressorts se détendent et poussent vers le haut les dômes 7 et les lentilles pour les sortir hors du liquide de conditionnement. Une fois la lentille séparée du liquide, l'utilisateur a accès à la lentille par son côté convexe, posée sur le dôme 7 et facile à prendre et à poser dans l'oeil. To take the lens, the user unscrews the respective lid 104 of the base member, so that the springs relax and push up the domes 7 and the lenses out of the conditioning liquid. Once the lens separated from the liquid, the user has access to the lens by its convex side, placed on the dome 7 and easy to take and put in the eye.
Aux figures 15, 15A, 15B, 15C et 15D, il est représenté encore un autre mode de réalisation de l'invention. In Figures 15, 15A, 15B, 15C and 15D there is shown yet another embodiment of the invention.
L' emballage comporte un élément 2 inférieur de base et un élément 3 supérieur formant couvercle qui comporte une plaque 9 de base rectangulaire de laquelle fait saillie une coque 120 qui définit avec la plaque 9 une enceinte 40 ouverte vers le dessous par une ouverture 13. l'enceinte est fermée par le dessous par un opercule 5 bouchant l'ouverture 13. Dans l'enceinte 40 fermée sont reçus le liquide de conditionnement, un élément 121 formant un dôme de support et la lentille 4. The package comprises a lower base element 2 and an upper lid element 3 which has a rectangular base plate 9 from which protrudes a shell 120 which defines with the plate 9 a chamber 40 open towards the bottom through an opening 13. the enclosure is closed from below by a cover 5 blocking the opening 13. In the enclosure 40 closed are received the conditioning liquid, a member 121 forming a support dome and the lens 4.
L' élément 2 de base comporte une plaque en forme de disque 6 de base de forme circulaire complémentaire de l'ouverture 13 de la coque 120. le disque 6 de base est percé d'un trou 124 central et un élément en forme de dôme 7 en passoire est disposé au dessus du trou 124 en 1' entourant . The basic element 2 comprises a disk-shaped base plate 6 of circular shape complementary to the opening 13 of the shell 120. The base disk 6 is pierced with a central hole 124 and a shaped element. dome 7 in the colander is disposed above the hole 124 in 1 'surrounding.
Du disque 6 s'étend en outre, du côté opposé au dôme 7, un tube 122 cylindrique circulaire mince et trois pattes 128 sont formées à la périphérie du disque 6. Ces pattes ont pour fonction d'assurer la fixation par serrage élastique du disque 6 contre la paroi latérale intérieure de l'enceinte 40. Pour ce faire, il est formé dans la paroi latérale intérieure de l'enceinte 40 des renfoncements 129 de forme complémentaire de celle des pattes 128. Lorsque les pattes se trouvent à l'intérieur des renfoncements 129, le disque 6 de base peut coulisser le long de la paroi de l'enceinte 40 de sorte que l'élément 3 couvercle peut être éloigné de l'élément 2 de base. Pour aider à cet éloignement, il est prévu à l'intérieur de la partie 122 cylindrique une entretoise 130 qui peut être prise par exemple entre le pouce et l'index de l'utilisateur pour manipuler le disque 8 et/ou le couvercle 3. Disk 6 further extends, on the opposite side to the dome 7, a thin circular cylindrical tube 122 and three tabs 128 are formed at the periphery of the disk 6. The purpose of these tabs is to secure the disk by elastic clamping. 6 against the inner side wall of the enclosure 40. To do this, it is formed in the inner side wall of the chamber 40 of the recesses 129 of complementary shape to that of the tabs 128. When the tabs are inside recesses 129, the base disc 6 can slide along the wall of the enclosure 40 so that the element 3 cover can be moved away from the element 2 base. To assist in this removal, there is provided inside the cylindrical portion 122 a spacer 130 which can be taken for example between the thumb and the index finger of the user to manipulate the disk 8 and / or the lid 3.
Lorsque les pattes 128 ne sont pas dans les renfoncements 129, elles portent de manière élastique contre la paroi latérale de l'enceinte 40 et assurent une fixation à force du disque 6 à l'élément couvercle. When the tabs 128 are not in the recesses 129, they bear elastically against the side wall of the chamber 40 and provide a force attachment of the disc 6 to the cover member.
Un opercule 5 est fixé à la face inférieure de la plaque 9, notamment par collage, adhésif, soudure ou analogue tel que classiquement connu pour la fixation d'opercule notamment dans le domaine des emballages de médicaments, de manière à boucher l'ouverture 13 et réaliser ainsi la fermeture de l'enceinte 40 avec en son sein du liquide de conditionnement, le dôme passoire et la lentille 4 posée sur le dôme, l'enceinte 40 étant emplie de liquide de conditionnement, au dessus et en dessous du dôme 7 et de la lentille. A lid 5 is fixed to the underside of the plate 9, in particular by gluing, adhesive, solder or the like as conventionally known for the attachment of a lid, particularly in the field of drug packages, so as to plug the opening 13 and thus to close the enclosure 40 with the conditioning liquid therein, the dome and the lens 4 placed on the dome, the chamber 40 being filled with liquid conditioning, above and below the dome 7 and the lens.
Pour prendre la lentille, l'utilisateur retire par pelage l'opercule 5 de la face inférieure de la plaque 9, de sorte que le liquide s'échappe par l'ouverture 13 de l'enceinte 40. Une fois le liquide évacué, la lentille a donc été séparée du liquide et l'utilisateur tourne à l'aide de l' entretoise 130 le disque 6 d'un quart de tour pour faire en sorte que les pattes 128 soient reçues dans les renfoncements 129 pour permettre le retrait par coulissement du couvercle pour ainsi faire apparaître la lentille sur le dôme avec sa convexité vers le haut. To pick up the lens, the user peels off the cover 5 from the underside of the plate 9, so that the liquid escapes through the opening 13 of the enclosure 40. Once the liquid has been evacuated, the Thus, the lens has been separated from the liquid and the user rotates the disc 130 by a quarter of a turn to ensure that the tabs 128 are received in the recesses 129 to allow sliding withdrawal. cover to make the lens appear on the dome with its convexity upwards.
Aux figures 16, 16A, 16B et 16C, il est décrit encore un autre mode de réalisation de l'invention. In Figures 16, 16A, 16B and 16C, there is described yet another embodiment of the invention.
L' étui ou emballage comporte un élément 2 de base et un élément 3 formant couvercle. The case or package includes a base member 2 and a lid member 3.
L'élément 2 de base comporte une plaque 6 de base sensiblement rectangulaire percée d'un trou 13, trou qui est entouré d'une coque de forme sensiblement hémisphérique faisant saillie de la face inférieure de la plaque 6 pour définir avec l'ouverture du trou 13 une enceinte 40 dans laquelle est reçu outre le liquide de conditionnement d'une part la lentille 4 et d'autre part un élément de support formant une surface de support en forme de dôme 7. Pour former le dôme 7, on a ici utiliser les quarts de disque comme dans les modes de réalisation des figures 9 ou 13. On aurait pu utiliser d'autres systèmes analogues pour former la surface de support, par exemple les barrettes des figures 8, 11 ou 14, les passoires des figures 3, 10 ou 15 ou tout autre support réalisant la même fonction consistant d'une part à avoir une forme convexe que la lentille peut épouser pour y être supporter avec sa convexité vers le haut et d' autre part à être perméable au liquide conditionnement pour permettre à ce dernier de maintenir la lentille humide par le dessus et le dessous lors de sa conservation. The basic element 2 comprises a substantially rectangular base plate 6 pierced with a hole 13, which hole is surrounded by a shell of substantially hemispherical shape projecting from the underside of the plate 6 to define with the opening of the hole 13 a chamber 40 in which is received in addition to the conditioning liquid on the one hand the lens 4 and on the other hand a support member forming a dome-shaped support surface 7. To form the dome 7, there is here use the quarter discs as in the embodiments of Figures 9 or 13. It could have used other similar systems to form the support surface, for example the bars of Figures 8, 11 or 14, the strainers of Figures 3 , 10 or 15 or any other medium performing the same function consisting on the one hand to have a convex shape that the lens can marry for there being supported with its convexity upwards and on the other hand being permeable to the conditioning liquid to allow the latter to maintain the moist lens from above and below during its storage.
Un canal 201 de forme demi cylindrique fait saillie de la plaque 6. Le canal a un rayon inférieur à la profondeur (également son rayon) de l'enceinte 40. Ce canal 201 débouche à la face supérieure de la plaque 6 et latéralement dans l'enceinte 40 mais est bouché à l'autre extrémité, par la patte 12. A half cylindrical channel 201 protrudes from the plate 6. The channel has a radius less than the depth (also its radius) of the chamber 40. This channel 201 opens to the upper face of the plate 6 and laterally into the chamber. enclosure 40 but is plugged at the other end, by the leg 12.
L'élément 3 formant couvercle est constitué d'un operculeThe element 3 forming a cover consists of a cover
205, comportant en outre une coque 206 en forme de demi cylindre de forme complémentaire du canal 201 faisant saillie de la face inférieure de l'opercule 205. 205, further comprising a hull 206 in the form of a half-cylinder of complementary shape of the channel 201 projecting from the underside of the lid 205.
A l'état emballé de la lentille 4, celle ci est reçue sur le dôme 7 et l'opercule est fixée, notamment par collage, adhésif, soudure ou analogue à l'élément de base de manière à boucher le trou 13 et fermer l'enceinte 40 tandis que le canal 201 reçoit la coque 206, de sorte que le liquide de conditionnement n'est pas présent dans le canal et ne se trouve que dans l'enceinte 40 défini par la coque hémisphérique. In the packaged state of the lens 4, it is received on the dome 7 and the lid is fixed, in particular by gluing, adhesive, solder or the like to the base member so as to plug the hole 13 and close the door. enclosure 40 while the channel 201 receives the shell 206, so that the conditioning liquid is not present in the channel and is found in the chamber 40 defined by the hemispherical shell.
Lorsque l'utilisateur veut prendre la lentille, il décolle l'opercule en libérant le canal 201 de la coqueWhen the user wants to take the lens, he takes off the lid by releasing channel 201 from the hull
206, de sorte que le liquide de conditionnement se trouvant dans l'enceinte 40 à une hauteur au dessus du canal passe dans le canal et est ainsi séparé de la lentille qui n'a plus alors de liquide de conditionnement au dessus d'elle et peut être prise par le doigt. 206, so that the conditioning liquid in the chamber 40 at a height above the channel passes into the channel and is thus separated from the lens which then no longer has a conditioning liquid above it and can be taken by the finger.
L'opercule 205 réalise ainsi dans ce mode de réalisation les deux fonctions de couvercle et de moyens de séparation du liquide de la lentille (cette dernière fonction en combinaison avec le canal 201). In this embodiment, the cap 205 thus makes the two functions of cover and means of separation of the liquid from the lens (the latter function in combination with channel 201).
Aux figures 17A à 17C, il est représenté un mode de réalisation de structure très proche de celui des figures 8 et 8A à 8C. In FIGS. 17A to 17C, there is shown an embodiment of structure very similar to that of FIGS. 8 and 8A to 8C.
Les différences sont principalement la forme du dôme, la présence d'une rainure formée autour du dôme dans la plaque de base qui reçoit un joint torique d' étanchéité, notamment en silicone, et une structure antiadhésive qui fait saillie de la face inférieure du couvercle, pour empêcher que la lentille ne se « colle » au couvercle. The differences are mainly the shape of the dome, the presence of a groove formed around the dome in the base plate which receives a sealing O-ring, in particular of silicone, and a nonstick structure which projects from the underside of the lid. , to prevent the lens from "sticking" to the lid.
Concernant la forme du dôme, dans ce mode de réalisation, il est formé par des quarts des disque comme les modes de réalisation des figures 12, 13 et 16. cependant, comme mentionné précédemment, ces deux types de dôme sont équivalents et interchangeables. On peut également prévoir à la place, une passoire, une grille ou toute autre forme analogue. Regarding the shape of the dome, in this embodiment, it is formed by quarter discs as the embodiments of Figures 12, 13 and 16. However, as mentioned above, these two types of dome are equivalent and interchangeable. It can also provide instead a strainer, a grid or any other similar form.
Concernant la rainure et le joint torique, comme on le voit le mieux à la figure 17B, la rainure 300 circulaire est formée dans la plaque 9 de l'élément 2 inférieur autour de la collerette circulaire 21 disposée autour du trou 13. La rainure 300 reçoit en son sein un joint torique 301 d' étanchéité . Lorsque le couvercle 3 vient s ' encliqueter par la patte 24 dans la rainure 22 circulaire formée dans la face extérieure de la collerette 21, l'extrémité inférieure de la nervure 25 de la patte 24 vient buter contre le joint torique de manière à assurer 1 ' étanchéité . On pourrait prévoir bien évidemment un tel agencement d' étanchéité dans l'ensemble des modes de réalisation de 1' invention . With respect to the groove and the O-ring, as best seen in FIG. 17B, the circular groove 300 is formed in the plate 9 of the lower member 2 around the circular collar 21 disposed around the hole 13. The groove 300 receives within it an O - ring seal 301. When the lid 3 is snapped by the lug 24 in the circular groove 22 formed in the outer face of the flange 21, the lower end of the rib 25 of the lug 24 abuts against the O-ring so as to ensure that 1 sealing. Obviously, such a sealing arrangement could be provided in all of the embodiments of the invention.
Enfin, des nervures 400 disposées en étoile font saillie de la face inférieure de la coque 10. Ces nervures ont une forme adaptée à la courbure de la lentille et viennent sensiblement en affleurement avec la lentille en laissant un petit jeu avec celle ci lorsque la lentille est reçue entre le dôme et la coque. La surface des nervures destinées à venir en contact avec la lentille est moletée pour empêcher que la lentille ne se « colle » et empêcher ainsi que la lentille « suive » le couvercle lorsque ce dernier est retiré. A la place d'un moletage, on pourrait prévoir d' autres formes mécaniques ou prévoir un revêtement anti-adhésif. Finally, ribs 400 arranged in a star project from the underside of the shell 10. These ribs have a shape adapted to the curvature of the lens and come substantially flush with the lens leaving a small clearance with the latter when the lens is received between the dome and the hull. The surface of the ribs intended to come into contact with the lens is knurled to prevent the lens from "sticking" and thus preventing the lens from "following" the lid when the lens is removed. Instead of a knurling, one could provide other mechanical forms or provide a non-stick coating.
On pourrait prévoir bien évidemment un tel agencement anti-adhésif dans l'ensemble des modes de réalisation de 1' invention . Obviously, such a non-stick arrangement could be provided in all the embodiments of the invention.
De manière générale, et notamment dans tous les modes de réalisation, le liquide de conditionnement peut être par exemple une solution aqueuse stérile, isotonique et sensiblement saline, pouvant contenir des adjuvants tels que l'acide borique, l'édétate disodique, le borate de sodium, le polaxamine et autres composants en faible concentratio . In general, and in particular in all the embodiments, the conditioning liquid may be, for example, a sterile, isotonic and substantially saline aqueous solution, which may contain adjuvants such as boric acid, disodium edetate, borate borate, and the like. sodium, polaxamine and other low concentratio components.
Concernant la matière en laquelle l'étui peut être fabriquée, il s'agit traditionnellement de polymères thermoplastiques, notamment injectés, tels que des polyoléfines , tels que le polyéthylène (PE) ou le polypropylène . L'étui peut cependant être en tout autre matériau approprié pour ce genre d'application. Regarding the material in which the case can be manufactured, it is traditionally thermoplastic polymers, in particular injected, such as polyolefins, such as polyethylene (PE) or polypropylene. The case may however be any other material suitable for this kind of application.
Concernant les dimensions, les étuis peuvent avoir une largeur comprise entre 20mm et 40 mm, une longueur comprise entre 20/25 mm et 100 mm, une longueur entre 20/25 mm et 50 mm et une épaisseur comprise entre 5mm et 30mm. Regarding the dimensions, the cases may have a width of between 20 mm and 40 mm, a length of between 20/25 mm and 100 mm, a length between 20/25 mm and 50 mm and a thickness of between 5 mm and 30 mm.
Par exemple pour le mode de réalisation de la figure 14, on peut avoir la largeur comprise entre 25mm et 40 mm, pour une longueur comprise entre 50 mm et 100mm et une épaisseur comprise entre 10 mm et 30mm, et pour les modes de réalisation des figures 1 à 13 et 15 à 17, on peut avoir la largeur comprise entre 20mm et 40 mm, pour une longueur comprise entre 20/25 mm et 50mm et une épaisseur comprise entre 5 mm et 20mm. For example, for the embodiment of FIG. 14, the width may be between 25 mm and 40 mm, for a length of between 50 mm and 100 mm and a thickness of between 10 mm and 30 mm, and for the embodiments of FIGS. Figures 1 to 13 and 15 to 17, one can have the width between 20mm and 40 mm, for a length between 20/25 mm and 50mm and a thickness between 5 mm and 20mm.
