Drinking Vessel Closure Assembly for Multi-Opening Spout Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drinking vessels with multiple drinking openings or non-planar spouts are difficult to seal effectively, especially when not in use, leading to potential leakage and temperature loss.
Innovation Solution
A closure assembly with a positioning member and sealing member that ensures the sealing member is oriented correctly for sealing multiple drinking openings, even if the spout has a curved or angled shape, by using a threaded connection that maintains the sealing orientation during attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closure assembly is used to seal multiple drinking openings, then sealing effectiveness is improved, but the device complexity increases
Solution Approach 1:
The closure assembly is divided into distinct functional components: a positioning member with orientation features and a separate sealing member. This segmentation allows each component to perform its specific function independently, ensuring reliable sealing of multiple drinking openings while maintaining manageable complexity through modular design.
Solution Approach 2:
The positioning member acts as an intermediary between the closure assembly and the spout, ensuring correct orientation and alignment. This intermediary component mediates the interaction between the sealing member and the multiple drinking openings, enabling effective sealing without requiring complex integration of all functions into a single component.
2Adaptability or versatility
If the spout has a curved or angled shape, then the drinking vessel design is more versatile, but sealing becomes more difficult
Solution Approach 1:
The positioning member incorporates orientation features with specific local geometries designed to match particular spout configurations (curved, angled, or straight). This local quality adaptation allows the same closure assembly design to effectively seal various spout shapes by adjusting the orientation features rather than redesigning the entire system.
Solution Approach 2:
The orientation features of the positioning member can be modified in terms of angle, curvature, and position to accommodate different spout geometries. By changing these parameters, the closure assembly maintains effective sealing across diverse spout designs without sacrificing versatility.
3Reliability
If the positioning member extends deep into the drinking opening for sealing, then sealing effectiveness is improved, but the ease of operation decreases
Solution Approach 1:
The positioning member is pre-configured with orientation features that automatically guide correct alignment as the closure assembly approaches the spout. This preliminary action of pre-positioning the orientation features ensures that the sealing member extends deep into the drinking opening for effective sealing while the self-aligning mechanism simplifies the operation for the user.

AI summary
A drinking vessel (10) including a beverage container (100) and a closure assembly (400) attachable to the beverage container.The beverage container has a spout (300) defining a first drinking opening (310) and a second drinking opening (320). The closure assembly includes a positioning member (700) and a sealing member (800). When the positioning member is in a sealing orientation, the positioning member can extend deep enough into the first drinking opening for the sealing member to seal the first drinking opening and the second drinking opening. When the positioning member is not in the sealing orientation, the positioning member cannot extend deep enough into the first drinking opening for the sealing member to seal the first drinking opening and the second drinking opening.
