Packaging Container With Selective Peel Sealing for Medical Device Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging containers allow the entire sealing film to be opened uniformly, exposing all parts of the medical device, risking improper handling and potential damage to functional components.
Innovation Solution
The packaging container is designed with a difficult-to-peel portion surrounding the protection target portion and an easy-to-peel portion for grasping, preventing the user from touching the wrong part by stopping the peeling process at the difficult-to-peel portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire sealing film is made uniformly easy to peel, then the user can easily open the packaging, but the user may touch and damage critical components of the medical device
Solution Approach 1:
The sealing film is designed with different peeling characteristics in different regions: the first region (peripheral portion) is configured to be easily peelable, while the second region (central portion covering critical components) is configured to be difficult to peel. This local differentiation allows users to easily open the packaging from the peripheral region while preventing accidental exposure and damage to critical components in the central region.
2Reliability
If the sealing film is made difficult to peel overall, then critical components are protected, but the user cannot easily open the packaging
Solution Approach 1:
The sealing film is segmented into functionally distinct regions: a first region (peripheral portion) that is easily peelable for opening the packaging, and a second region (central portion) that is difficult to peel for protecting critical components. This segmentation allows the packaging to provide both easy opening capability and component protection simultaneously.
3Productivity
If the entire sealing film peels off at once, then opening is quick and simple, but all medical devices are exposed simultaneously increasing risk of wrong handling
Solution Approach 1:
The sealing film is divided into a first region that peels off easily for quick opening and a second region that remains adhered to protect critical components. This segmentation enables rapid packaging opening while maintaining continuous protection of sensitive areas, preventing erroneous handling even during the opening process.
Solution Approach 2:
The sealing film is pre-configured with different peeling resistances in different regions before use. The first region is pre-prepared to peel easily for quick access, while the second region is pre-prepared to remain adhered and protect critical components during the opening operation, ensuring protection is maintained throughout the opening process.

AI summary
Regarding a packaging container (10) for accommodating a medical device (12) (stored object) having a protection target portion to be avoided from contact when taken out and a graspable portion that can be grasped, a seal portion of a sealing film (18) peelably bonded to a container body (16) is provided with a difficult-to-peel portion (46) bonded with a relatively strong strength in a part surrounding the protection target portion of the medical device, and provided with an easy-to-peel portion (48) bonded with a weak strength in a part surrounding the graspable portion of the medical device.
