Contact Lens Packaging with Pressed Optical Zone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional contact lens packaging containers are bulky, difficult to stack, and inefficient in packaging multiple lenses, making it hard to carry and wear contact lenses easily, as they require fingers to be submerged in solution and are not designed for easy lens retrieval.
Innovation Solution
A contact lens packaging container with edge and optical zone protection portions, allowing lenses to be packaged in a compact form with pressed optical zones, oriented for easy removal and featuring a finger support groove for easy foil opening, enabling efficient packaging of multiple lenses in a small space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional soft lens packaging container is used, then a single contact lens can be packaged, but the container becomes several times larger than the lens, making it difficult to stack and carry
Solution Approach 1:
The container body is divided into multiple accommodation portions (first accommodation portion and second accommodation portion) that can individually hold contact lenses. This segmentation allows efficient use of space while maintaining protective functionality for each lens separately.
Solution Approach 2:
The contact lens is nested within the accommodation portion of the container body, which is sealed by packaging foils. The lens is positioned within the curved surface of the accommodation portion, creating a compact nested structure that minimizes container volume while protecting the lens.
2Ease of operation
If fingers are used to pick up the contact lens from the solution, then the lens can be retrieved, but fingers become submerged in the contact lens solution causing contamination and difficulty in handling
Solution Approach 1:
The packaging foil is designed with a tear line that allows it to be easily torn open by fingers. The foil is fusibly bonded to the container body, creating a pre-prepared opening mechanism that enables lens retrieval without submerging fingers in the solution.
Solution Approach 2:
The packaging foil is extracted or removed from the sealed container to access the contact lens. The foil acts as a separable barrier that can be taken out to retrieve the lens without direct finger contact with the solution.
3Reliability
If the contact lens is packaged in a sealed container with solution, then the lens is protected, but it becomes difficult to open the packaging foil and retrieve the lens in a wearable form
Solution Approach 1:
The packaging foil is pre-bonded to the container body with a defined tear line, creating a preliminary opening mechanism. This allows the foil to be easily torn open by fingers to retrieve the contact lens in the correct orientation for wearing.

AI summary
The present invention relates to a contact lens packaging container. According to an embodiment of the present invention, an edge protection portion configured such that the peripheral zone of a contact lens is supported thereon in order to prevent the efficacy of the contact lens from being damaged and an optical zone protection portion configured such that the optical zone of the contact lens is supported in the state of having been pressed are formed on each accommodation portion of a body, thereby providing the advantageous effect of enabling contact lenses to be efficiently packaged in a narrow space and thus minimizing the size of the contact lens packaging container.
