Sterile Packaging With Folded Air-Pocket Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sterile packaging materials face challenges in providing effective shock absorption and maintaining sterility, with shock-absorbing cardboard boxes requiring dry storage and plastic films having standardized cushion sizes that may leave unprotected product sections.
Innovation Solution
A sterile packaging design featuring a first sterile barrier, a second sterile barrier with integrated air pockets separated by a fold-down edge, and an outer protective packaging, where the air pockets align to form a receiving space around the first sterile barrier, ensuring complete protection and sterility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If shock-absorbing cardboard boxes are used, then shock absorption is provided, but they require dry storage to maintain shape and are plastically deformed by external forces
Solution Approach 1:
The patent changes the material parameter from cardboard to elastic plastic film, which fundamentally alters the shock absorption mechanism from plastic deformation to elastic deformation. This allows the packaging to maintain its shock absorption capability under varying storage conditions including humidity, as the elastic material returns to its original shape regardless of environmental moisture.
2Strength
If standardized shock-absorbing plastic films are used, then shock absorption is provided, but products may protrude in sections between cushioning pockets
Solution Approach 1:
The patent segments the shock absorption function into multiple independent air pockets distributed throughout the packaging. Each air pocket acts as an independent cushioning unit that can adapt to the product shape, ensuring complete coverage without protruding sections while maintaining effective shock absorption.
Solution Approach 2:
The patent employs dynamically adaptable air pockets formed by folding edges that can change shape and position based on the product contours. This dynamic adaptation ensures that the air pockets conform to the product shape, eliminating unprotected sections while maintaining shock absorption effectiveness.
3Manufacturing precision
If multiple layers of shock-absorbing plastic films are used to protect protruding sections, then complete product protection is achieved, but the overall packaging layer becomes considerably thicker
Solution Approach 1:
The patent merges the sterile barrier function and shock absorption function into a single integrated structure. The air pockets are formed within the sterile barrier packaging itself, eliminating the need for separate shock-absorbing layers and reducing overall packaging thickness while maintaining complete product protection.
Solution Approach 2:
The patent creates a multi-functional packaging structure where the sterile barrier simultaneously provides sterility protection and shock absorption through integrated air pockets. This universal design eliminates the need for additional dedicated shock-absorbing materials, reducing packaging thickness while achieving complete product coverage.
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 design provides double sterility and effective cushioning against shocks and vibrations without additional packaging materials, ensuring the product is fully enclosed and protected from external forces while maintaining sterility.
Implementation Method 1
the second sterile barrier comprises a film or a double membrane that forms at least two air pockets
Implementation Method 2
The two air pockets are separated from each other by a predefined fold-down or folding edge, whereby, in the folded-down state of the double membrane or film along the fold-down or folding edge, the two air pockets come to lie in alignment with each other

AI summary
A medicinal sterile packaging for packaging a medicinal product includes a first sterile barrier designed to receive the medicinal product in a heat-sealed/sealed manner. A second sterile barrier forms a receiving space for receiving the first sterile barrier in a heat-sealed/sealed manner. An outer protective packaging receives the first sterile barrier and the second sterile barrier. The second sterile barrier is a film that forms at least two air pockets separated from one another in the film by a predefined fold-over or folding edge. When the film is folded over along the fold-over or folding edge, the two air pockets come to lie one on top of the other in alignment, such that the receiving space can be produced between them.
