Microneedle Patch Container with Anti-Static Release Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers are inadequate for hygienically storing and transporting microneedle patches with flexible substrates, as they fail to prevent static attraction and ensure aseptic preservation, making it difficult to maintain the pharmacological effectiveness from manufacturing to use.
Innovation Solution
A microneedle patch container with recessed bottom surfaces, side surfaces connecting to the periphery, and protruding bottom surfaces to hold the release sheet, featuring an anti-static design and aseptic packaging options, such as sterilized film sheets, to prevent static attraction and ensure hygienic storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional containers are used for storing microneedle patches, then the patches can be stored, but static attraction occurs and aseptic preservation cannot be ensured
Solution Approach 1:
The patent introduces a release sheet as an intermediary element between the microneedle array and the container. This release sheet prevents direct contact between the microneedles and container surfaces, thereby eliminating static attraction effects while maintaining aseptic preservation during storage and transport
Solution Approach 2:
The patent employs a flexible release sheet that can be peeled off before application. This thin film structure effectively blocks static electricity generation and accumulation, while allowing the microneedle patch to maintain its aseptic state throughout the storage period
2Ease of operation
If microneedle patches with flexible substrates are stored, then they can be transported, but conventional containers cannot ensure hygienic storage and prevent static attraction
Solution Approach 1:
The release sheet serves as a mediator that facilitates easy handling of the flexible microneedle patch during transport. It prevents static attraction between the flexible substrate and container surfaces, while allowing the patch to be easily removed and applied when needed
3Adaptability or versatility
If the microneedle array is made flexible to fit non-planar faces, then it can be applied to curved surfaces, but conventional solid substrate containers cannot be used
Solution Approach 1:
The patent adopts a flexible substrate for the microneedle array that can conform to non-planar facial surfaces. The container is designed with a corresponding flexible release sheet that accommodates this flexibility, enabling the patch to be stored in a simple container structure while maintaining its adaptability to curved surfaces
Solution Approach 2:
The container design with a release sheet serves multiple functions: it provides structural support during storage, prevents static attraction, maintains aseptic conditions, and facilitates easy removal and application of the flexible microneedle patch to various facial contours
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The container effectively holds microneedle patches hygienically, prevents static attraction, and allows for easy handling and stacking, ensuring the patches remain effective and aseptic until use, addressing the challenges of static interference and preservation.
Implementation Method 1
the lid not having recessed portions in a position corresponding to other part of the bottom-surface protruding portion... in order to avoid influence of static electricity

AI summary
The present invention provides a microneedle patch container for effectively and hygienically securing a microneedle patch from manufacture to use. The container has a bottom surface recessed from the peripheral portion towards the center, a side surface connected to the bottom surface and the peripheral portion, and a bottom-surface protruding portion protruding from the bottom surface. The flexible release-type sheet portion of the microneedle patch is secured to the protruding portion on the bottom surface. A lid can also be used which has a recessed portion pressing against the microneedle patch secured to the bottom-surface protruding portion of the container in the position corresponding to the bottom-surface protruding portion. This is preferably housed inside a pouch molded from sterilized paper or sterilized film in order to keep the microneedle patch in an aseptic state.
