A recently filed patent (Publication Number: US20230249874A1) describes a contact lens blister package that aims to provide a sterile and convenient packaging solution for contact lenses. The package consists of a thermoplastic base member with a blister cavity to hold the lens and a flange that includes a sealing ring region. The package also contains a liquid contact lens packaging solution and an unworn contact lens. A sealing member is hermetically sealed to the sealing ring region to maintain the sterility of the lens.

One unique feature of the package is the inclusion of connecting features on the flange, which allow the thermoplastic base member to mechanically fasten and interlock with another base member to form an assembly. This feature enables multiple blister packages to be connected together, providing a convenient and organized storage solution for contact lenses.

The thermoplastic base member is made from a recyclable plastic material, specifically polypropylene. This choice of material ensures that the package is environmentally friendly and can be easily recycled.

The sealing ring region of the flange has a non-circular configuration that includes a vertex, which helps to securely seal the package and prevent any leakage or contamination.

The gripping portion of the flange is planar, making it easy for contact lens wearers to hold and handle the package.

The connecting feature on the flange can be either an interlocking feature or a stackable feature. The interlocking feature can include a hole, a clip, a latch, or a combination thereof. The stackable feature includes a receptacle formed on the gripping portion of the flange.

The package also includes stabilizing legs that extend from the bottom surface of the flange and circumscribe the convex exterior surface of the bowl, providing stability and preventing the package from tipping over.

Overall, this patent describes a contact lens blister package that offers a sterile and convenient solution for storing and packaging contact lenses. The inclusion of connecting features allows for easy organization and storage of multiple packages, while the use of recyclable materials ensures environmental sustainability.
