Elastic Foil Bag Cushioning for Pharmaceutical Bottle Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging units for pharmaceutical tablets and capsules in plastic bottles fail to adequately protect against vibrations and impacts, leading to breakage and deformation due to direct transmission of shocks and relative movement of contents.
Innovation Solution
A flexible, elastic film bag is used inside the plastic bottle, which contracts elastically upon filling and automatically presses contents together, forming a hollow space that cushions against impacts, and a spring element or compressible material in the intermediate space further absorbs shocks, preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tablets, coated tablets or capsules are packed loosely in plastic bottles, then ease of filling and accessibility is improved, but vibrations and impacts cause tablet breakage or capsule deformation
Solution Approach 1:
The patent employs a flexible foil bag that can be collapsed and compressed, allowing it to adapt to the volume of contents while providing protective cushioning. The foil bag's flexibility enables it to conform to tablets, coated tablets or capsules, distributing impact forces and preventing breakage while maintaining ease of filling operations.
Solution Approach 2:
The foil bag is designed to provide cushioning protection before impacts occur. By positioning the foil bag to surround the pharmaceutical products and creating an intermediate space with cushioning material, the system prepares protective barriers in advance that absorb and distribute impact forces during transport, preventing tablet breakage and capsule deformation.
2Reliability
If air-filled bags or cushions are inserted into plastic bottles to dampen impacts, then transport protection is improved, but device complexity and filling difficulty increase
Solution Approach 1:
The patent merges the containment function and the cushioning function into a single integrated foil bag structure. The foil bag serves both as the container for the pharmaceutical products and as the cushioning element that provides impact protection, eliminating the need for separate air-filled bags or cushions and simplifying the overall packaging structure.
Solution Approach 2:
The foil bag is designed to automatically provide cushioning protection through its own structural properties and the intermediate space it creates, without requiring additional active components or complex mechanisms. The cushioning effect arises naturally from the foil bag's flexibility and the space it maintains between products and the bottle wall.
3Stability of the object's composition
If individual tablets or capsules are stabilized with spring elements or closures, then relative movement is reduced, but impact damping and overall protection remain insufficient
Solution Approach 1:
The foil bag acts as an intermediary element between the pharmaceutical products and the external environment. It provides a protective interface that stabilizes products by preventing direct contact and impact with the bottle wall, while simultaneously serving as a cushioning barrier that absorbs and distributes impact forces, enhancing overall impact resistance.
Solution Approach 2:
The flexible foil bag surrounding the products provides both stabilization and impact protection. Its flexibility allows it to conform to product arrangements and provide gentle containment, while its structural integrity and the intermediate space it creates offer cushioning against external impacts, addressing both stability and impact resistance requirements.
4Reliability
If a hollow intermediate space is formed between foil bag and bottle wall, then impact cushioning is improved, but space utilization and compactness decrease
Solution Approach 1:
The foil bag is designed to dynamically adjust its volume and shape based on the amount of contents and external conditions. During filling, it expands to accommodate products, and during transport, it maintains an optimized intermediate space for cushioning. This dynamic adaptability allows the system to provide impact protection while minimizing excess empty space, improving overall space utilization.
Solution Approach 2:
The flexible nature of the foil bag allows it to create an optimized intermediate space that provides adequate cushioning while conforming to the bottle's internal geometry and the volume of contents. This flexibility enables the system to maintain protective spacing without excessive volume waste, as the foil bag adjusts its form to efficiently use available space.
