Vessel Lid with Sharp Pouring Edge to Prevent Wall Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thick-walled vessels with rounded edges, such as glass mixers and carafes, exhibit undesirable pouring behavior where liquids tend to flow along the outer wall instead of pouring out smoothly, especially with viscous or mixed drinks, leading to clogging and cleaning issues with aerators.
Innovation Solution
A lid for vessels, particularly mixers, featuring a pouring opening that extends to the edge with a sharp transition, designed in two parts: a lid base with a spout opening that can be sealed by a rocker-style spout closure, which also functions as a measuring cup for pressing in fruits and protecting the operator, and a flexible lid base with sealing lips for secure fit and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vessel has thick walls with rounded edges for safety and stability, then the vessel is safer and more stable, but the liquid flows along the outer wall instead of pouring out smoothly
Solution Approach 1:
The lid is divided into two separate parts: a lid base and a lid cover. The lid base contains the pouring opening and forms a closed perimeter, while the lid cover seals over it. This segmentation allows the pouring edge to be formed by the lid base structure rather than the vessel wall, resolving the contradiction between vessel wall rounding for safety and sharp edge needed for proper pouring.
2Ease of operation
If the pouring opening is made large for easy pouring, then pouring is easier, but the lid base structure becomes more complex
Solution Approach 1:
The pouring function is extracted from the vessel wall structure and transferred to the lid base. The pouring opening in the lid base can be designed with optimal dimensions independent of the vessel wall thickness, allowing easy pouring while keeping the lid base structure relatively simple and integrated with the vessel.
3Reliability
If the lid base forms a closed perimeter for secure sealing, then the seal is more secure, but the transition to pouring opening creates complex geometry
Solution Approach 1:
The lid structure is segmented into the lid base with closed perimeter for sealing and the lid cover for closure. The pouring opening is formed in the lid base as a separate feature, allowing the closed perimeter structure to maintain secure sealing while the pouring opening geometry is optimized independently for smooth liquid flow.

AI summary
The invention relates to a lid (1) for a vessel, particularly for a mixer (2), comprising at least one pouring opening (4) in a lid base (3), through which contents of said vessel can be poured out of the vessel through the lid base (3), and a pouring closure (5) which is designed for insertion into same in order to seal said pouring opening (4). The pouring opening (4) extends to the edge (7) of the lid, with a closed lid base perimeter (6) being formed, wherein the transition portion (8) from said pouring opening (4) over the closed lid base perimeter (6) forms a pouring edge (9).
