Pour Spout With Abrupt Cutoff Lip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spouts on lids often cause spillage and fluid buildup on the lid due to inefficient fluid pouring, leading to undesired outcomes.
Innovation Solution
A pour spout is designed with a back portion, an orifice for fluid flow, and a lip with an abrupt 'cutoff' edge, allowing fluid to exit through primary and secondary pouring regions, minimizing spillage and fluid accumulation on the lid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional spout is used on a lid, then the spout allows fluid to be poured out, but fluid spillage and buildup on the lid occurs
Solution Approach 1:
The spout incorporates a lip with an abrupt cutoff edge at its opening, creating a localized geometric feature that redirects fluid flow. This local structural modification causes fluid to follow the lip's contour and exit in a controlled direction, preventing spillage and buildup on the lid while maintaining efficient pouring
Solution Approach 2:
The spout lip is designed with an asymmetric abrupt cutoff edge rather than a symmetric or rounded opening. This asymmetric geometry creates specific flow patterns that direct fluid away from the lid surface, resolving the spillage problem while preserving pouring functionality
2Object-generated harmful factors
If the spout lip has an abrupt cutoff edge, then fluid flow direction is controlled to reduce spillage, but manufacturing precision requirements increase
Solution Approach 1:
The spout lip with the abrupt cutoff edge is integrally formed with the spout body as a single molded piece. This merging of the lip feature into the main spout structure eliminates the need for separate manufacturing steps or assembly, reducing overall manufacturing precision requirements while maintaining the functional benefits of the abrupt edge geometry

AI summary
A spout is provided herein, which may be incorporated in a cap that connects to a lid. The spout may include a back portion, an orifice, and a lip. The orifice may be configured for fluid to flow out of the spout, and the lip positioned near a front portion of the spout. Fluid may exit the spout via at least one of a primary pouring region and a secondary pouring region.
