One-Press Bottle Cap With Elastic Clamping Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bottle caps are complex, labor-consuming, and pose safety risks due to high counter-acting forces when opening, often resulting in water splashing and potential finger damage.
Innovation Solution
A bottle cap design featuring a clamping groove, positioning ring, fixing ring, and oval elastic clamping ring with a pressing piece, allowing for one-handed operation by separating the elastic clamping ring from the groove to unlock and re-lock the cap, ensuring safe and rapid opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a buckle type structure is used, then the bottle cap can be securely closed, but the operation becomes more labor-consuming and water can easily splash out when opened
Solution Approach 1:
The elastic clamping ring provides dynamic locking and unlocking action. When the button is pressed, the elastic ring deforms to release the clamping grooves, enabling quick one-handed opening without complex buckling operations while maintaining secure closure when at rest
Solution Approach 2:
The elastic clamping ring automatically engages with the clamping grooves to secure the bottle cap and automatically releases when the button is pressed, providing self-service locking and unlocking without requiring complex manual operations
2Reliability
If a spiral structure is used, then the bottle cap can be securely closed, but opening requires rotating the bottle cap which is complex and labor-consuming
Solution Approach 1:
The elastic clamping ring provides dynamic locking and unlocking action. When the button is pressed, the elastic ring deforms to release the clamping grooves, enabling quick one-handed opening without complex buckling operations while maintaining secure closure when at rest
Solution Approach 2:
The elastic clamping ring automatically engages with the clamping grooves to secure the bottle cap and automatically releases when the button is pressed, providing self-service locking and unlocking without requiring complex manual operations
3Reliability
If a large counter-acting force is generated at the moment of opening, then the bottle cap can be securely held, but the safety is low due to potential finger damage
Solution Approach 1:
The elastic material of the clamping ring provides cushioning effect, absorbing the release force gradually rather than creating a sudden large counter-acting force, thereby protecting fingers from damage while maintaining secure holding during normal use
Solution Approach 2:
The elastic properties of the clamping ring change the force characteristics during opening, transforming a potentially harmful sudden force into a controlled, gradual release that maintains security while protecting the user
4Ease of manufacture
If a simple structure is used, then the production cost is reduced, but the operational safety and reliability may be compromised
Solution Approach 1:
The bottle cap is divided into functional segments: the elastic clamping ring for locking, the button for actuation, and the clamping grooves for engagement. This segmentation allows each component to be simple in structure while collectively providing reliable and safe operation
Solution Approach 2:
The elastic clamping ring automatically engages with the clamping grooves to secure the bottle cap and automatically releases when the button is pressed, providing self-service locking and unlocking without requiring complex manual operations
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 simplifies operation, reduces labor, enhances safety, and prevents water leakage with an elastic sealing gasket, while allowing easy one-key opening and closing, improving the structural reliability and reducing production costs.
Implementation Method 1
an oval elastic clamping ring with a pressing piece... Two ends of a shorter shaft of the elastic clamping ring are located in the clamping groove to lock a connection between the bottle cap and the bottle opening, and are configured to stretch when the pressing piece is pressed and opened

AI summary
A bottle cap capable of being opened by one press includes a bottle opening (11) and a bottle cap (1), and further includes a positioning ring (3), a fixing ring (10), and an oval elastic clamping ring (8). An interval (13) is provided between the positioning ring (3) and the fixing ring (10). Two ends of a long shaft of the elastic clamping ring (8) are located in the interval (13), and one of the ends of the long shaft of the elastic clamping ring (8) is provided with a pressing piece (7). A clamping groove (12) is circumferentially formed on a side wall of the bottle opening (11) at a position corresponding to the elastic snap ring (8). Two ends of a short shaft of the elastic clamping ring (8) are located in the clamping groove (12) to lock the connection of the bottle cap (1) to the bottle opening (11), and are configured to stretch as the pressing piece (7) is pressed, so as to disengage from the clamping groove (12) and enter the slot (13), thereby unlocking the connection of the bottle cap (1) to the bottle opening (11).
