BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package combined with a contact lens packaging container for holding at least one hydrophilic contact lens in a sterilized aqueous solution. In particular, the present invention relates to a plurality of disposable hydrophilic contact lenses that are held in a specified number of packaging containers that are collectively housed in a box-shaped container or carton, for use by consumers over a period of time. It relates to a packaging means combined with a packaging container which makes it possible to provide contact lenses in a determined quantity or in a quantity measured essentially.

The packaging of hydrophilic contact lenses in sterile aqueous solutions is well known in the contact lens manufacturing art. In particular, such packaging containers are generally made up of so-called blister packages (packages having a hemispherical shape; hereinafter the name blister package is used), which blister packages store hydrophilic contact lenses. And then by the doctor
Or used to distribute to consumers who want to wear contact lenses. Generally, such hydrophilic contact lenses are discarded after one-time or short-term use and are made from a suitable hydrophilic polymeric material. Depending on the composition of the polymer, these materials have a composition of about 20
% To 90% or more of water content of hydroxyethyl methacrylate copolymer and the like. In general, such contact lenses are stored in sterile aqueous solution, usually isotonic saline solution, to prevent dehydration and to keep the lens ready for wear.

2. Description of the Related Art Conventionally, contact lens manufacturers have been
Usually, glass bottles with stoppers containing sterile saline solution in which hydrophilic contact lenses are dipped have been used as containers for the storage and shipping of contact lenses. Each bottle was sealed by a suitable silicone stopper and fitted with a metal lid as a top lid as a safety closure. When a patient attempts to remove a contact lens from a bottle for use, the metal lid safety device must first be torn from the bottle, then the stopper removed and a suitable plastic The lens will be taken out of the bottle by using the tweezers or by pouring out the contents. This involves performing extremely complex procedures. The reason is,
In practice, due to the transparent nature of the contact lens, which is invisible to the human eye, it was difficult to grab and remove the contact lens from the saline solution in the bottle.

More recently, a method of retaining 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, inexpensive and suitable manner, while At the same time, it has become easier for doctors or patients to easily remove contact lenses. Such as isotonic saline solution,
A blister package adapted to provide a sterile, sealed storage environment for disposable or single-use hydrophilic contact lenses by the method of immersing the lens in a sterile aqueous solution is provided by Martine.

Therefore, it further improves the use and versatility of the blister package construction. Moreover, the above-described constructions primarily allow for the use of such blister packages for dispensing individual contact lenses, such blister packages usually being either separate or single. The packaging can be packaged in bulk in larger containers, such as cardboard or cardboard of the usual construction used in retail lenses.

Therefore, it is an important aspect to be able to provide users of such disposable hydrophilic contact lenses with a defined quantity of contact lenses. Disposable contact lenses are typically worn for only one day, and in essence, they are typically worn for only 8 to 18 hours, and then discarded for 24 hours. Thus, once a contact lens offer is packaged, it can be stored by the user for a period of time, for example, 3
An indication can be given to replenish the contact lens offer, such as a zero day period. Accordingly, the present invention contemplates providing a packaging container for a defined quantity of such hydrophilic contact lenses. These packagings are placed in a carton and are quick in terms of the quantity of hydrophilic contact lenses stored in them,
You can judge accurately. Such packaging is
It has a compact property that completely protects hydrophilic contact lenses.
