Closure device for a container for liquids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices for liquid containers require complex and difficult-to-manufacture components to prevent splashing and ensure a good seal, making them challenging to assemble and clean, especially for children and individuals with disabilities.
Innovation Solution
A simplified closure device with an elastically deformable membrane that switches between resting and working configurations, featuring a membrane with a main body and lower body, allowing easy assembly and cleaning, and comprising openings for air passage without liquid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex components with elaborate shapes are used to prevent splashing and ensure sealing, then the sealing performance and splash prevention are improved, but the manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The patent combines multiple functions (sealing, splash prevention, air passage) into a single integrated membrane component. The membrane includes a main body for sealing, a lower body with openings for air passage, and edge portions that engage with the container rim to prevent splashing. This integration eliminates the need for separate gaskets, splash guards, and retaining elements, thereby reducing manufacturing complexity while maintaining reliable sealing and splash prevention.
2Adaptability or versatility
If multiple separate components are used to achieve closure functions, then the functionality is ensured, but the assembly and cleaning processes become more difficult
Solution Approach 1:
The membrane is designed as a single-piece component that performs multiple closure functions simultaneously. The main body provides sealing, the lower body with openings enables air passage while preventing liquid leakage, and the edge portions ensure proper engagement with the container. This unified structure is easier to manufacture and assemble compared to multiple separate components, while maintaining full closure functionality.
3Reliability
If components with narrow recesses and elaborate shapes are used, then the sealing and splash prevention are achieved, but the cleaning accessibility is reduced
Solution Approach 1:
The membrane features a simplified integrated design without narrow recesses or hard-to-access areas. The smooth surface and lack of complex internal structures make it easy to clean while maintaining effective sealing through the engagement of edge portions with the container rim and the configuration of the main and lower bodies.
4Ease of manufacture
If a simplified membrane structure is used, then the manufacturing and cleaning are easier, but the functionality to prevent splashing and ensure sealing must be maintained
Solution Approach 1:
The membrane integrates sealing, air passage, and splash prevention functions into a single simplified structure. The main body ensures sealing, the lower body with openings allows air passage, and the edge portions prevent splashing. This unified design achieves all required functionalities while maintaining manufacturing simplicity and ease of cleaning.
