Gravitational Leak Testing for Medicament Sachets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Topical analgesic products in multi-dose containers often experience inaccurate unit dose dispensing due to leak issues in packaging, leading to patient underdoses or overdoses, necessitating a reliable method for leak testing in medicament sachets and pouches.
Innovation Solution
A leak testing system comprising a base section, a press section, and guide rods, where the medicament sachet or pouch is compressed between the base and press sections using gravitational forces, allowing for parallel surfaces to engage and test for leaks without requiring an external power source, facilitating accurate detection of seal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multi-dose containers are used for topical analgesics, then packaging convenience is improved, but dispensing accuracy deteriorates due to leak issues
Solution Approach 1:
The invention divides the multi-dose container into individual single-unit sachets or pouches, each containing a precise dose. This segmentation ensures that each unit is independently sealed and dosed accurately, eliminating the leak and dispensing accuracy issues associated with multi-dose containers while maintaining packaging convenience.
2Measurement precision
If single unit packages are used for medicament, then dispensing accuracy is improved, but packaging complexity increases
Solution Approach 1:
The invention employs disposable single-unit sachets or pouches that are simple in structure but effective for their intended purpose. Each unit is designed to be used once and then discarded, eliminating the need for complex reusable packaging systems while ensuring accurate dispensing. The simplicity of the single-use design reduces packaging complexity compared to sophisticated multi-dose systems.
3Device complexity
If leak testing system uses gravitational forces and parallel surfaces, then device complexity is reduced, but testing precision may worsen without external power source
Solution Approach 1:
The leak testing system is designed to be self-service, utilizing the weight of the press section itself to generate the necessary compressive force. The parallel surfaces are engineered to create sufficient pressure through gravity alone, eliminating the need for external power sources or complex actuation mechanisms. This self-service approach maintains testing precision while minimizing device complexity.
Solution Approach 2:
The system employs parallel surfaces that distribute force evenly across the sachet or pouch during compression. By creating an equipotential compression field through the parallel geometry, the system ensures uniform pressure distribution using only gravitational force, achieving reliable leak detection without requiring powered mechanisms to generate or distribute force.

AI summary
A leak testing system (210) for medicament sachets (200) is disclosed. The system (210) includes a base section (220) having a flat surface (226). A plurality of guide rods (230) extend from this flat surface (226) of the base section (220). A press section (240) incorporates a plurality of through-holes (242) that are used to movably mount the press section (240) on the noted guide rods (230). The press section (240) includes a flat surface (246) that is maintained in at least substantially parallel relation to the flat surface (226) of the base section (220). A medicament pouch (200) may be compressed between these flat surfaces (226, 246) of the base section (220) and the press section (240) by sliding the press section (240) along the guide rods (230) and in the direction of the base section (240). Multiple press plates can be added to adjust the force and weight to test for leaks.
