Sliding Closure Assembly for Leak-Tight Viscous Product Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closure systems fail to provide a leak-tight and easy-to-operate solution that can be used as both a bottle and a tottle, requiring minimal effort for opening and closing, especially for viscous products.
Innovation Solution
A closure assembly comprising a disc-shaped cap, a container head with parallel tracks and recesses, and a closure strip with an arcuate monorail, allowing horizontal sliding and vertical pivoting to ensure leak-proof closure, while enabling the container to be inverted and used as a tottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded screw closure is used, then leak-tight closure is achieved, but operation requires undue pressure and effort
Solution Approach 1:
The closure is divided into a cap portion and a closure portion that can move independently relative to each other. The closure portion slides horizontally within the cap portion along a track, separating the opening/closing action from the sealing function, enabling easy operation while maintaining leak-tight closure.
Solution Approach 2:
The closure portion is designed to move dynamically between open and closed positions through horizontal sliding motion guided by a track. This dynamic mechanism allows the closure to transition smoothly between states with minimal effort, eliminating the need for threaded rotation or excessive pressure.
2Ease of operation
If a flip-top closure is used, then ease of operation is improved, but leak-tight closure cannot be ensured
Solution Approach 1:
The closure system separates the operable cap portion from the sealing closure portion. The cap provides easy flip-top operation while the closure portion with plug ensures leak-tight sealing, combining the advantages of both closure types through functional segmentation.
Solution Approach 2:
The closure portion acts as an intermediary between the easily operated cap and the dispensing orifice. It translates the simple cap movement into effective sealing action through the plug, achieving both ease of operation and leak-tight closure.
3Productivity
If a traditional bottle is used, then normal dispensing is achieved, but dispensing remaining viscous contents requires excessive effort
Solution Approach 1:
The container is designed with dual functionality: it can be used in normal upright position for standard dispensing and inverted to function as a tottle for dispensing remaining viscous contents. This multi-functionality eliminates the need for separate containers for different dispensing scenarios.
Solution Approach 2:
The closure mechanism accommodates dynamic usage scenarios by allowing the container to be inverted without compromising the sealing function. The sliding closure portion and plug system maintain effectiveness in both upright and inverted positions, enabling easy dispensing of remaining contents.
