Definitions

• the present invention relates to a case for packages of contact lenses .
• one handling problem is that a person has different visual defects on respective eye and with that, it is common that different strength for right and left eye, respectively, of the contact lenses is frequent, and for that reason it is thus important to have a safe control of the different contact lenses . It is also important to be able to keep the different contact lenses apart if several persons in the same housekeeping, or for example persons who are sharing hotel room or luggage, are carrying contact lenses .
• Containers , cases, boxes and storage covers are previously known for storing of contact lenses, but that there are no known solution that admit a sufficient satisfactory simplicity, organization and handling of the contact lenses .
• the hitherto known storage boxes are only related to matching spaces for the size of strips of contact lenses .
• GB-A-2341942 it is previously known a casing for storage of contact lenses , that comprises a first container arranged to a second container and a lid arranged between the container parts . In the containers may different obj ects be stored, such as strips of contact lens packages .
• One obj ect with the present invention is to achieve a portable packing for storage and carriage of packages for contact lenses that at least partly eliminates those drawbacks that are associated with arrangement according to the state of the art .
• Yet another obj ect is to achieve a casing for packages of contact lenses, in particular intended for disposable packages of one-day-lenses, that facilitates a simple, secure and practical handling and organization of the contact lens packages .
• These obj ects are achieved by a case for packages of contact lenses , intended in particular for disposable packages of contact lenses, according to ⁇ the present invention as defined in claim 1.
• the case comprises a first and a second lid, which lids are rotatably arranged in relation to each other by way of a hinge or the similar .
• At least the first lid comprises a longitudinal guide rail, at an edge part of the first lid, and is arranged along substantially the whole edge part .
• the guide rail is intended to act in releasably engagement with a package of a contact lens for retaining one or more contact lens packages during position within the lid and which guide rail permits that the package of a contact lens is displaceable in the longitudinal direction of the case .
• a short side of the first lid is formed with an open end part, whereby a contact lens package that is releasably retained by the guide rail in the lid is displaceable out through and removable from the open end part .
• One advantage with this solution according to the present invention is that a secure storage of the contact lens packages in the case is achieved thanks to the arranged guide rail in the lid. Yet another advantage is that the present invention permits a simple handling of contact lenses and eliminates the need to remove whole strips of contact lens packages from the case . By displacing the whole strip with the contact lens packages retained in the lid, a desired contact lens package can be discharged outside the open end part and be torn off from the strip .
• the guide rail may have a shape that is adapted for engagement with different shapes of contact lens packages , so called blister packages , of contact lenses .
• the most commonly contact lens packages of today for contact lenses comprises a plane sheet of plastic with a cup-shaped recess in which lens liquid and contact lens is placed .
• the cup recess is sealed with a foil or the similar, which is tightly arranged on one side of the plastic sheet .
• the plastic sheet comprises flange sections that originate from the production of the contact lens packages .
• the guide rail may use these flange sections in order to retain contact lens packages in the lid owing to that the flange section is inserted in a slot formed by the guide rail .

• Fig. ID shows in an enlarged view a cross-section A-A of the case according to Fig . IA-B in closed position with contact lenses arranged in the case , of another kind than in Fig . 1C, in the first lid and in the second lid, and
• Fig. 2 shows schematically the discharge of a contact lens package arranged to a strip with proj ecting contact lens packages in a case according to the present invention .
• a case 2.for contact lens packages is shown, according to an embodiment of the present invention, in Fig . IA-D .
• the case 2 comprises a first lid and a second lid 6, which lids are rotatably R arranged relative to each other by way of a hinge 8 or the like .
• the lids 4 , 6 are arranged closely adj acent to each other, they define a interior delimited delimitation space S for protection and secure storage of contact lens packages .
• Fig IC-D shows a cross-section of the case in closed position, that is with the lids arranged adj acent to each other, with contact lenses arranged in the first lid 4 and in the second lid 6 in the case .
• At least a first lid 4 comprises a longitudinal guide rail 10 , at an edge part 12 of the first lid 4 , that is arranged along substantially the whole edge part 12.
• the guide rail 10 is intended to act in relesable engagement with a contact lens package 14 , 16 (see Fig . IC-D and 2 ) , for retaining of one or more contact lens packages 14 , 16 placed inside the lid 4 , by means of pressure of the guide rail against a respective contact lens package .
• Two or more contact lens packages can be arranged to each other in form of a strip 17 (see Fig . 2) .
• the other lid 6 may preferably comprise a longitudinal guide rail 10' that is arranged along substantially the whole edge part 12' of the second lid for releasably retaining of one or more contact lens packages
• the guide rail 10, 10' permits that the contact lens package can be displaced in the longitudinal direction L of the case .
• this ' configuration that facilitates arrangement of contact lens packages 14 , 16 in both the first and the second lids 4, 6, may contact lens packages for left eye be arranged in one of the lids and for the right eye be arranged in the other lid, whereby a simple handling and a good organization is achieved.
• a first short side 18 of the first lid 4 is formed with an open end part 20 , whereby a contact lens package 14, 16 that is releasably retained of the guide rail 10 in the lid 4 can be discharged and removed through the open end part 20.
• a second short side 22 of the first lid may be formed with a closed end part 24. Furthermore, may also a first short side 25 , according to the shown embodiment , of the second lid 6 that is adjacent to the first short side 18 of a first lid 4 be formed with a closed end part 26. In addition, a second short side 28 of the second lid 6 that is adj acent to the second short side
• the guide rail 10, 10 ' may have different shapes .
• the guide rail have a J-shaped, or the like, projection 32 that projects from the edge part 12, 12' of a respective lid 4 , 6, which proj ection 32 has an outer end 34 that is freely arranged in the lid .
• the guide rail forms a slot 35 intended for engagement with a proj ecting flange section 36, 36' of a contact lens package 14 , 16 which is inserted from the short side 18 , 30 in the respective lid 4 , 6.

• flange sections 36, 36' are used on the one side of the contact lens package in order to retain the contact lens packages 14 , 16 in the lid thanks to that the flange section 36, 36' is inserted in the slot 35 that is formed by the guide rail 10, 10 ' .
• the case may comprise one or more locking devices , a first, locking device in the shape of a central snap-lock.
• This first locking device comprises a clamp part 42 at an edge of one lid 6, which when closing the case 2 engages a matching slot 44 in the second lid 4.
