Contact Lens Blister Pack Label And Method For Adjoining Blister Packs
Contact lens packaging (2) includes two or more individual, sealed blister packs (1) coupled together by a connecting label (5), which includes a uni-axial shear polymer film (6). The connecting label (5) is arranged and oriented such that the tear direction of the polymer film (6) is parallel to a line (A) bisecting adjacent blister packs (1). Methods of binding together two or more blister packs (1) are also described.
CONTACT LENS PACKAGE AND CONTACT LENS PACKAGING METHOD
The present disclosure proposes a contact lens package. The contact lens package includes a first substrate, a contact lens, and a guard ring. The contact lens is disposed on the first substrate. The guard ring is disposed on the first substrate and surrounds the contact lens, wherein the guard ring is fixed on a side surface of the first substrate. The contact lens and the guard ring are surrounded and sealed in the first substrate.
PACKAGING SOLUTIONS
A packaging system for the storage of an ophthalmic device is disclosed. The packaging system includes a sealed container containing one or more unused ophthalmic devices immersed in an aqueous packaging solution that includes ectoine or an ophthalmologically acceptable ectoine derivative. The aqueous packaging solution has an osmolality of at least about 150 mOsm/kg, a pH of about 6 to about 9 and is sterilized.
Contact lens blister package with double layer foil component
A blister package for a contact lens is provided that includes a body and a seal, one or both of which is made up of a double layer foil component. The double layer foil component can be a seal component made of a sheet of material folded upon itself and defining a seal, a flap, and a fold. The seal and the flap intersect at the fold and the flap can be pulled away from the seal to form a pull tab useful to peel back the seal and open the bowl. The body can also, or instead, be made of a double layer foil component that forms at least the bowl such that the bottom of the bowl is double-walled. The double-walled bowl exhibits improved strength and can be provided with strengthening features such as ribs, ridges, channels, or grooves.
METHOD FOR DETECTING THE PRESENCE OR ABSENCE OF AN OPHTHALMIC LENS WITHIN A RECEPTACLE
The present invention relates to a method and a lens detection station for detecting the presence or absence of an ophthalmic lens capable of absorbing UV-light, in particular a contact lens, in a receptacle. The method comprises the steps of: irradiating at least a portion of said receptacle where said ophthalmic lens is supposedly accommodated with UV-light, said receptacle having an absorbance for said UV-light which is significantly different from that of the ophthalmic lens, detecting UV-light coming from said irradiated portion of said receptacle where said ophthalmic lens is supposedly accommodated, analyzing said detected UV-light, and from said analysis of said detected UV-light determining the presence or absence of a said ophthalmic lens.
Contact lens packaging solutions
The present invention relates to improved contact lens products which not only have an improved and sustainable wettability. The contact lens product of the invention comprises a soft hydrogel contact lens immersed and autoclaved in a packaging solution including a polyoxyethylene-polyoxybutylene block copolymer and a high molecular weight copolymer of N-vinylpyrrolidone and at least one amino-containing vinylic monomer. The present invention also provides methods for making contact lens products of the invention.
Method for transporting a packaging shell of an ophthalmic lens package
A method for transporting a packaging shell (1) of an ophthalmic lens package comprises the steps of at a start location providing a packaging shell (1) comprising a depression (10), and a flange (11) completely surrounding the depression (10), providing a suction cup (2) having an opening (21) at a distal end thereof, which is completely surrounded by a rim (22) sized and shaped to engage the flange (11) in an engagement area completely enclosing the depression (10), positioning the suction cup (2) and the packaging shell (1) such that the rim (22) and the engagement area of the flange (11) face each other, moving the suction cup (2) and the packaging shell (1) towards each other, applying suction through the opening (21) of the suction cup (2), moving the suction cup (2) with the packaging shell (1) adhered thereto to the destination location, at the destination location releasing the suction, wherein a flexible sealing gasket (3) is arranged at the rim (22) to sealingly engage the flange (11) in the engagement area.

The double-walled bowl exhibits improved strength and can be provided with strengthening features such as ribs, ridges, channels, or grooves.
APPARATUS FOR SEALING AN OPHTHALMIC LENS PACKAGE
An apparatus for thermally bonding together a cover film of an ophthalmic lens package and a base part of the package, including a carrier for supporting the base part with film arranged thereon; a bonding unit above the carrier having a mounting plate with a bonding stamp extending therefrom, the bonding stamp having a mounting portion fixedly attached to the mounting plate, a bonding head arranged beneath the mounting portion with a heatable bonding contour on a side of the bonding head facing the carrier, and an articulated connector arranged between and connecting the mounting portion and the bonding head; and an actuator for performing movement of the carrier and the bonding stamp towards and away from each other for thermally bonding the film with the base part by pressing the heated bonding contour against the film and subsequent separation of the bonding head from the cover film bonded to the base part, the articulated connector being a cardanic joint with two rotational axes.
Systems and Methods for Multi-Stage Sealing of Contact Lens Packaging
A contact lens package may include a first package layer, a second package layer, a lens receiving area defined between the first and second package layers, a first seal portion between the first and second package layers extending around a first portion of the lens receiving area, a second seal portion between the first and second package layers extending around a second portion of the lens receiving area, and the second seal portion having different sealing properties than the first seal portion. The second seal portion together with the first seal portion complete a seal around the lens receiving area. The first seal portion defines an unsealed gap at a location around the lens receiving area, and the second seal portion closes the gap. The gap allows a flow of fluids after a formation of the first seal.
