Rotating Cap Adjusting Member for Variable Fluid Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bottle caps require users to reposition the bottle and change their holding posture to adjust the flow rate, which is inconvenient, especially when trying to slow down the flow near the end of dispensing.
Innovation Solution
A cap design with a rotatable adjusting member that varies the size of the fluid flow passageway by aligning first and second openings, allowing for adjustable flow rates without changing the bottle's position, enabling adjustments during dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional bottle caps with multiple outlet holes are used, then flow rate adjustment is possible, but the user must reposition the bottle and change holding posture to align different holes with the pouring direction
Solution Approach 1:
The cap employs a rotatable adjusting member with multiple openings that can dynamically change orientation relative to the outlet. This allows the user to rotate the adjusting member to align different openings with the outlet, thereby dynamically adjusting the flow rate without needing to reposition the bottle or change holding posture.
Solution Approach 2:
The adjusting member serves multiple functions: it acts as both a flow control mechanism and an alignment mechanism. By integrating the rotation capability directly into the cap structure, the device eliminates the need for separate bottle repositioning actions, making the flow rate adjustment self-contained and universally applicable regardless of bottle orientation.
2Adaptability or versatility
If the user releases grip to reposition the bottle for flow rate adjustment, then different outlet holes can be aligned, but the dispensing action is interrupted
Solution Approach 1:
The rotatable adjusting member allows continuous flow rate adjustment during dispensing without interrupting the action. The user can rotate the adjusting member with one hand while maintaining grip on the bottle, enabling dynamic flow control that preserves the continuity of the dispensing process.
3Adaptability or versatility
If multiple fixed-size outlet holes are provided, then different flow rates can be achieved, but the structure becomes more complex
Solution Approach 1:
Instead of providing multiple fixed outlet holes of different sizes, the invention uses a single adjustable opening mechanism. The adjusting member with multiple openings that can be rotated into position effectively provides variable flow rates through a single dynamic structure, reducing overall structural complexity compared to multiple fixed openings.

AI summary
The invention provides a cap for a container. The cap comprises a cover member having an outlet and at least one first opening; a base member engageable with the container and having an inlet; an adjusting member co-axially connected with and rotatably movable relative to the cover member and the base member; the adjusting member having at least one second opening adapted to cooperate with the at least one first opening to define a fluid flow passageway connecting the inlet of the base member with the outlet of the cover member; wherein the adjusting member is actuatable at an exterior of the cap, such that actuation of the adjusting member causes the at least one second opening to rotate relative to the at least one first opening thereby varying a size of the fluid flow passageway connecting the inlet of the base member with the outlet of the cover member.
