Seal Bottle Assembly Pressure Control Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seal caps for bottles fail to effectively maintain a pressure difference between the interior and exterior, allowing air to enter the bottle and lack a secure mechanism to prevent accidental opening, especially by children.
Innovation Solution
A seal bottle assembly with a cap and control unit that adjusts pressure by using a radial hole with a restriction ring and stop plates, allowing the cap to be easily removed by pushing the control part inward and securely sealed by pulling it outward, while preventing unintentional opening through rotational contact with blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical seal cap is used to prevent easy opening, then security against accidental opening is improved, but air can still enter the bottle without restriction and pressure balance is not maintained
Solution Approach 1:
The patent applies pneumatic principles by using pressure differential created through the radial hole and restriction ring mechanism. When the cap is properly sealed, the restriction ring limits air flow through the radial hole, creating a pressure difference between the interior and exterior of the bottle that prevents accidental opening while still allowing controlled pressure equalization during intentional opening.
Solution Approach 2:
The patent changes the pressure parameter between the bottle interior and exterior by using the control part mechanism. The radial hole with restriction ring allows pressure equalization when the control part is in the first position, while blocking pressure equalization when in the second position, thereby dynamically changing the pressure parameter to achieve both sealing and security functions.
2Reliability
If the cap is designed to be securely sealed with pressure difference, then sealing effectiveness is improved, but the cap becomes difficult to remove and operation complexity increases
Solution Approach 1:
The patent applies dynamics by making the cap's sealing state changeable through the control part mechanism. The cap can dynamically transition between a sealed state (with pressure difference) and an open state (with pressure equalization) by moving the control part between two positions, making the normally difficult-to-remove cap easily removable when needed.
Solution Approach 2:
The patent uses preliminary action by requiring the user to first move the control part to the first position before removing the cap. This preliminary action of moving the control part equalizes the pressure first, eliminating the sealing force that would otherwise make cap removal difficult, and then the cap can be easily taken off.
3Ease of operation
If the radial hole allows free air flow for pressure balance, then ease of opening is improved, but the seal effectiveness is compromised and air enters without restriction
Solution Approach 1:
The patent makes the radial hole's air flow capability dynamic through the restriction ring and control part interaction. The radial hole can dynamically switch between allowing restricted air flow (when control part is in first position) and allowing free air flow (when control part is in second position), thereby balancing ease of opening and seal effectiveness based on operational needs.
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 solution ensures the cap can be easily separated from the bottle when pushed inward and securely sealed when pulled outward, maintaining pressure balance and preventing accidental opening, thus effectively sealing the bottle and enhancing safety.
Implementation Method 1
the pressure in the first and second rooms is different from that of outside of the bottle assembly so that the cap is not removable relative to the bottle
Implementation Method 2
the pressure in the first and second rooms is the same as that of outside of the bottle assembly so that the cap is removable relative to the bottle

AI summary
A seal bottle assembly includes a bottle and a cap is removably mounted to the top opening of the bottle to seal the first room. The cap includes a radial hole defined radially therethrough. A switch unit includes a seal part located in the cap, and a control part located outside of the cap. When the control part is pushed toward the seal part, the pressure in the cap and the bottle is the same as that of outside of the bottle assembly so that the cap is removable relative to the bottle. When the control part is pulled away from the seal part and the seal part is moved to seal a communication between the first and second rooms. The pressure in the cap and the bottle is different from that of outside of the bottle assembly so that the cap is not removable relative to the bottle.
