Packaging arrangement for contact lenses

Abstract

A packaging arrangement for the containment of at least one hydrophilic contact lens in a sterile aqueous solution. More specifically, pursuant to the packaging arrangement, a plurality of disposable hydrophilic contact lenses are contained in a specific number of individual packaging arrangements collectively housed in a box-like container or carton so as to provide a specified or essentially measured supply of contact lenses for use by a consumer over a predetermined period of time.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a packaging arrangement for the containment of at least one hydrophilic contact lens in a sterile aqueous solution. More specifically, the invention pertains to a packaging arrangement wherein a plurality of disposable hydrophilic contact lenses are contained in a specific number of individual packaging arrangements collectively housed in a box-like container or carton so as to provide a specified or essentially measured supply of contact lenses for use by a consumer over a predetermined period of time.The packaging of hydrophilic contact lenses in a sterile aqueous solution is well known in the contact lens manufacturing technology. In particular, such packaging arrangements generally consist of so-called blister packages which are employed for the storage and dispensing of the hydrophilic contact lenses by a medical practitioner or to consumer who intends to wear the contact lenses. Generally, suc...

Benefits of technology

Each of the blister package base members which has a rectangular outstanding planar flange encompassing a respective cavity therein, the latter of which is offset towards one edge, includes a depending wall portion formed at the opposite edge of the flange so as to provide a support for a superimposed or therebeneath located array of blister packages, thereby formulating rigidly supported and compact packaging arrangements within the carton, in which the cavities containing the hydrophilic contact lenses of superimposed arrays are substantially protected against potentially damaging external influences, such as shocks or impacts which may be imparted to the filled carton during handling thereof.

A more specific object of the invention is to provide a packaging arrangement for a plurality of hydrophilic contact lenses in which a plurality of blister packages each having a cavity containing one of the contact lenses in a sterile aqueous solution are interconnected in an array by a single flexible cover sheet containing weakening lines intermediate the base members of the packages enabling separation of individual of the blister packages from the array for dispensing the contact lens from the separated package.

Yet another object of the present invention is to provide structure for blister packages of the type described for the storage of hydrophilic contact lenses in a sterile aqueous environment, wherein pluralities of arrays of blister packages are arranged in specified mutually inverted superimposed relationship with a carton, and incorporate integrally formed supporting structure so as to be compactly and protectively supported within the carton.

Problems solved by technology

This entailed the implementation of an extremely complicated procedure, since the contact lens was difficult to grasp and remove from the saline solution contained in the bottle due to the transparent nature of the contact lens which rendered it practically invisible to the human eye.
