[0001]
[Industrial application fields]
  The present invention relates to a package synthesized with a contact lens packaging container for holding at least one hydrophilic contact lens in a sterilizing aqueous solution. In particular, the present invention provides that a plurality of disposable hydrophilic contact lenses are held in a specific quantity of packaging containers collectively contained in a box-like container or carton, for use by consumers for a predetermined period of time. The invention relates to a packaging container and a synthetic packaging means which makes it possible to provide a contact lens of a determined or essentially quantity measured.
[0002]
  Packaging hydrophilic contact lenses in a sterile aqueous solution is well known in the contact lens manufacturing field. In particular, such packaging containers are generally composed of so-called blister packages (packages having a hemispherical shape, hereinafter referred to as blister package names), which store hydrophilic contact lenses. And used by physicians or for dispensing to consumers who want to wear contact lenses. In general, such hydrophilic contact lenses are discarded after a one-time or short period of use and are made from a suitable hydrophilic polymeric material. These materials include copolymers of hydroxyethyl methacrylate containing about 20% to 90% or more water depending on the polymer composition. In general, such contact lenses are stored in an aqueous sterilizing solution and are usually stored in an isotonic saline solution to prevent dehydration and keep the lens ready for wearing.
[0003]
[Prior art]
  Traditionally, contact lens manufacturers have typically used stoppered glass bottles containing sterile saline solution to soak hydrophilic contact lenses as containers for contact lens storage and shipping. Each bottle was sealed with a suitable silicone stopper and was fitted with a metallic lid as the top lid as a safety seal. When a patient tries to remove a contact lens from a bottle for use, it is necessary to first remove the metal lid safety device from the bottle, after which the stopper is removed and a suitable plastic is removed. The lens is removed from the jar by using the tweezers or by pouring out the contents. This entails performing extremely complex procedures. The reason is that it was difficult to grasp and remove the contact lens from the saline solution in the bottle because of the transparent nature of the contact lens that is practically invisible to the human eye.
[0004]
  More recently, a method of holding in the form of a blister package for hydrophilic contact lenses has been developed, which makes it possible to store and ship hydrophilic contact lenses in a simple and cheap suitable manner, while at the same time It has become easier to remove contact lenses easily by a doctor or patient. How to immerse the lens in a sterilized aqueous solution, such as isotonic saline solutionAccordingFor single-use or one-time use hydrophilic contact lensesInProviding a sterilized and sealed storage environmentOfferA blister package is described in US Pat.
