Drinking vessel with closure assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drinking vessels with multiple drinking openings, especially those with curved or angled spouts, are difficult to seal effectively, 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 in the correct orientation for sealing multiple drinking openings, using a threaded connection to compress the sealing member between the cap and spout, ensuring a secure seal.
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 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 device complexity through modular design.
2Reliability
If the positioning member extends deep into the drinking opening for effective sealing, then sealing effectiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The positioning member incorporates pre-formed orientation features such as ridges or flanges that automatically align with corresponding features in the drinking opening during insertion. This preliminary orientation action ensures the sealing member reaches the correct position without requiring precise manual alignment, maintaining ease of operation while achieving deep extension for effective sealing.
3Reliability
If the sealing member is compressed between the cap and spout to ensure a secure seal, then sealing effectiveness is improved, but device complexity increases
Solution Approach 1:
The closure assembly merges the sealing function with the fastening function by integrating the sealing member into the threaded cap structure. The cap simultaneously provides both the compressive force needed to seal the drinking openings and the threaded connection for secure attachment to the spout, achieving reliable sealing without adding separate complex mechanisms.

AI summary
A drinking vessel including a beverage container and a closure assembly attachable to the beverage container. The beverage container has a spout defining a first drinking opening and a second drinking opening. The closure assembly includes a positioning member and a sealing member. 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.
