Drinking bottle closure with a rotatable closure cap for an insulated bottle or for an insulated mug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking bottle closures with rotatable caps often suffer from poor sealing due to increased internal pressure and accidental unscrewing, especially when the cap is positioned above the sealing ring, leading to potential leaks and inconvenience.
Innovation Solution
A drinking bottle closure design where the cap is positioned below the sealing ring and supported by a housing element, utilizing a left-hand thread for intuitive closing and a threaded pin within a slipping clutch element to prevent accidental opening, ensuring a secure and efficient sealing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the closure cap is positioned above the sealing ring, then the construction allows for a small diameter, but the sealing effect is cancelled when internal pressure increases and the cap may be inadvertently turned off
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the closure cap below the sealing ring instead of above it. This inversion resolves the technical contradiction because the cap's lower position allows internal pressure to press the cap more strongly against the sealing ring, enhancing the sealing effect while preventing accidental opening, all while maintaining a compact small diameter design.
2Productivity
If the closure cap is rotated beyond the open position, then rapid opening and closing is achieved, but the cap may be inadvertently turned off by the user
Solution Approach 1:
The patent applies preliminary anti-action by designing the closure cap with a predetermined rotation limit feature. The cap is constructed to automatically stop at the open position and cannot be rotated beyond it, preventing inadvertent closing while still allowing rapid opening and closing operations through the controlled rotation range.
3Reliability
If the sealing element is arranged below the sealing edge, then the sealing effect is improved under pressure, but the maximum axial displacement and angle of rotation are limited
Solution Approach 1:
The patent utilizes parameter changes by designing the closure cap with a threaded connection that converts rotational motion into controlled axial displacement. The thread pitch and engagement length are specifically designed to provide sufficient rotation range for easy operation while ensuring the cap stops at the correct position to maintain optimal sealing contact under pressure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances sealing efficacy, prevents accidental unscrewing, and allows for easy handling, maintaining a small diameter suitable for small bottles and mugs, while providing a visually distinct open position indicator.
Implementation Method 1
utilizing a left-hand thread for intuitive closing
Implementation Method 2
threaded pin within a slipping clutch element to prevent accidental opening
Implementation Method 3
threaded pin within a slipping clutch element to prevent accidental opening
Implementation Method 4
any internal pressure arising inside a bottle which is connected to the drinking bottle cap presses the cap more strongly against the sealing and increases the sealing effect
