Abstract | The packages described by this invention all have reduced "head space," that is, the distance from lid to lens. Packages contain dimples to achieve this reduced head space. Specifically, packages are designed with dimple sag equal to or less than 1.90-mm, or volume displaced equal to or less than 360µl. Combined with the existing primary packaging, it has been found that such conditions provide for reduction in folded lens rate during shipping and handling. As well, lenses stored or having an extended time in low head space packages in a "foil down" orientation now have characteristics closer lenses stored in a "foil up orientation."
Les emballages selon l'invention présentent tous un "espace libre", c'est-à-dire la distance entre l'opercule et la lentille, réduit. A cette fin, les emballages comportent des alvéoles. Plus spécifiquement, les emballages sont conçus de façon à présenter un affaissement des alvéoles inférieur ou égal à 1,90 mm, ou une variation de volume inférieure ou égale à 360 µl. En association avec l'emballage principal existant, on a découvert que de telles conditions conduisent à une réduction du taux de lentilles pliées lors du transport et de la manipulation. En outre, les lentilles stockées ou séjournant de manière prolongée dans des emballages à espace libre réduit dans une orientation dans laquelle la pellicule se trouve en bas ont désormais des caractéristiques se rapprochant davantage de celles des lentilles stockées dans une orientation dans laquelle la pellicule se trouve en haut. |
