Drinking Container Collar Assembly for Full-Rim Spill Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional spill-proof containers are complex and restrict the area from which a user can drink, making them unsuitable for young children transitioning from bottles to open cups, as they often result in spillage when knocked over.
Innovation Solution
A drinking container assembly with a collar and seal assembly that allows drinking from any location around the rim, featuring a frustoconical design with handles for easy handling, a resilient sealing ring, and a fastener assembly to secure the collar to the container, enabling fluid to be drawn from any position along the rim without leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spill-proof container covers are used, then spillage is prevented, but the device complexity increases due to complex parts and valve structures
Solution Approach 1:
The patent removes the complex valve structures and internal mechanisms from traditional spill-proof covers, replacing them with a simple collar assembly that relies on the container's own rim geometry to provide spill prevention functionality.
Solution Approach 2:
The collar assembly serves multiple functions: it provides spill prevention, defines a drinking rim, and works with various container types, eliminating the need for specialized valve mechanisms while achieving reliable spill-proof performance.
2Reliability
If traditional spill-proof container covers are used, then spillage is prevented, but the area from which a user can drink is restricted
Solution Approach 1:
The collar assembly divides the drinking interface into distinct functional zones: the spill-proof collar structure and the open rim area, allowing users to access the full circumferential rim for drinking while the collar maintains spill prevention at the base.
Solution Approach 2:
The invention transitions from restricting drinking to a single spout location to enabling drinking from any point around the entire circumferential rim, effectively adding dimensional freedom to the drinking interface while maintaining spill prevention.
3Ease of operation
If conventional open cups are used, then ease of operation is improved, but spillage occurs when knocked over
Solution Approach 1:
The collar assembly acts as a pre-positioned protective barrier at the base of the container, providing spill prevention coverage before any knocking or tilting occurs, allowing the container to function like an open cup without the downside of spillage.

AI summary
A non-spill drinking container assembly having a container with an open upper portion and closed lower portion. A collar may be removably attached to the upper portion of the container and may have an upper surface with a contour. A seal may be removably attached to the collar and cover the contour of the upper surface of the collar.
