Articulated Capping Device for Carbonated Beverage Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capping devices for containers are not suitable for carbonated beverages due to pressure-induced unwanted openings and limited height, restricting their applications.
Innovation Solution
A capping device with a lower ring and cap assembly that includes an articulation mechanism allowing axial displacement and pivotal movement, enabling the cap to be taller and securely attached, with support elements for improved positioning and a locking mechanism for the tilted open position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cap is designed to fit into the neck of the container with simple pivoting movement, then the device structure is simple, but the cap height is limited and it cannot resist pressure from carbonated beverages
Solution Approach 1:
The lower ring is divided into two articulated sections that can pivot relative to each other. This segmentation allows the cap to have greater height while maintaining a compact configuration when closed, resolving the contradiction between device simplicity and cap height requirements.
Solution Approach 2:
The lower ring sections are made dynamically movable through articulation, allowing the structure to adapt its configuration. When opened, the sections pivot to accommodate taller cap designs, while maintaining structural integrity and simplicity in the closed state.
2Ease of operation
If the cap uses simple pivoting movement between closed and open positions, then the operation is simple, but the cap cannot remain securely closed under pressure from carbonated beverages
Solution Approach 1:
The support element is positioned to preemptively counteract the opening force before it can cause unwanted opening. When the lower ring sections are in their raised position, the support element prevents the cap from being forced open by carbonated beverage pressure, thus maintaining reliability without complicating operation.
3Reliability
If the cap is designed to fit tightly into the neck, then the sealing is effective, but the cap cannot be easily removed or positioned during opening
Solution Approach 1:
The articulated lower ring sections provide dynamic movement capability that facilitates easy cap removal and positioning. The sections can pivot to guide the cap during removal while maintaining the tight fit and sealing effectiveness when closed, resolving the contradiction between secure sealing and ease of operation.

AI summary
Capping device (1) intended to be fixed on a neck (2) of a container to seal an orifice (5) in said neck (2), including the capping device: - a lower ring (3) including a first section (15) intended to be axially retained on the neck (2) and a second section (16); - a cap (4); and - an articulation device (6) that connects the cap (4) to the second section (16) of the lower ring (3). The first section (15) and the second section (16) are articulated to each other so that the second section (16) pivots with respect to the first section (15) from a lowered position to a raised position to allow the cap (4) to move axially away from the neck (2) from the closed position to a released position wherein said cap (4) is no longer coupled to the neck (2) of the container.
