Pourer With Offset Walls For Viscous Liquid Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pourers for viscous liquids like oil and vinegar fail to effectively direct the liquid flow to one pouring orifice without leakage from the other orifice, leading to uncontrolled pouring and potential fraud through refilling.
Innovation Solution
A pourer design with offset walls and a stem between them, creating distinct pouring areas, where the lower wall acts as a 'breakwater' to slow down liquid flow and prevent leakage, while also serving as a deterrent against fraudulent refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single pouring orifice is used, then the structure is simple, but the user cannot control the pouring rate for different liquid volumes
Solution Approach 1:
The single pouring orifice is segmented into multiple pouring orifices (first pouring orifice and second pouring orifice) with different sizes. This allows the user to select different pouring rates by choosing which orifice to use, thereby controlling the pouring rate for different liquid volumes without significantly complicating the overall structure.
Solution Approach 2:
The pourer incorporates a rotatable component that can dynamically switch between different pouring orifices. This dynamic mechanism allows the user to rotate the container or pourer to align the desired pouring orifice with the pouring direction, providing adaptability for different pouring needs while maintaining a relatively simple structure.
2Adaptability or versatility
If two pouring orifices are provided, then different pouring rates can be achieved, but liquid may leak from the non-selected orifice
Solution Approach 1:
A liquid interception member is introduced as an intermediary element between the two pouring orifices. This member acts as a barrier that blocks liquid flow to the non-selected orifice while allowing liquid to flow through the selected orifice. The interception member effectively prevents liquid leakage from the non-selected orifice, ensuring reliable liquid flow control.
Solution Approach 2:
The liquid interception member is positioned and configured to preemptively block liquid flow paths that would otherwise lead to the non-selected pouring orifice. By establishing this preliminary barrier, the system prevents the harmful effect of liquid leakage before it can occur, ensuring that liquid only flows through the intended orifice.
3Ease of operation
If a conical bottom is used to direct liquid flow, then the structure is simple, but it is poorly effective in directing liquid toward the selected orifice
Solution Approach 1:
The liquid interception member serves as an intermediary that actively directs liquid flow toward the selected pouring orifice. Unlike a passive conical bottom, this member can be positioned and configured to effectively guide liquid flow, ensuring reliable direction control while maintaining ease of operation.
Solution Approach 2:
The pourer incorporates localized flow direction features such as inclined surfaces or guide channels near the selected pouring orifice. These local quality modifications create effective flow direction control in the critical area where liquid needs to be directed, without requiring a complete redesign of the entire pourer structure.
4Device complexity
If a diametral partition is used to separate liquid flow, then the structure is simple, but it is inadequate in effectively directing liquid
Solution Approach 1:
Instead of relying on a simple diametral partition, the invention introduces localized flow direction features such as inclined surfaces, guide channels, or strategically positioned interception members. These local quality modifications create effective flow direction control in the critical areas where liquid needs to be directed, achieving reliable flow direction without excessive structural complexity.
Solution Approach 2:
The liquid interception member is arranged in an offset position relative to the pouring body axis, creating a three-dimensional flow control structure. This dimensional arrangement allows the member to effectively intercept and redirect liquid flow in multiple directions, achieving reliable flow direction control without requiring a complex multi-component structure.

Function Achieved in This Case
The pourer ensures controlled liquid flow to the desired orifice, reducing leakage and preventing unauthorized refilling by using offset walls to manage flow rates and act as an obstacle.

AI summary
A pourer comprises a pouring body and members for liquid interception disposed inside the pouring body to form a first pouring orifice and a second pouring orifice, which define first and second pouring areas respectively, wherein the first pouring area is larger than the second pouring area. The members for liquid interception include a first wall and a second wall arranged in offset positions in the longitudinal direction and projecting into the pouring body from the inner surface of the pouring body.
