Vacuum Sealing Cap Pivoting Mechanism for Easy Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum sealing caps for containers are inconvenient to use due to the difficulty in opening and closing, especially when using multiple resilient clip fasteners, which require complex manipulation to assemble or remove the cap from the container.
Innovation Solution
A vacuum sealing cap design featuring an outer cap body, an inner cap body, a sealing gasket, a slide member, and an operating member that pivots between positions to easily seal and unseal the container by moving the inner cap body relative to the outer cap body, facilitated by a spring element for quick detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple resilient clip fasteners are used to secure the vacuum sealing cap, then the sealing reliability is improved, but the ease of operation deteriorates because each clip fastener must be individually manipulated
Solution Approach 1:
Multiple resilient clip fasteners are merged into a single integrated resilient clip fastener structure that engages with multiple positions on the container body simultaneously, allowing the entire cap assembly to be secured or removed with a single operational action rather than manipulating multiple separate clips
Solution Approach 2:
The resilient clip fastener is designed with multi-functionality to perform both sealing and securing functions through a single component, and can engage multiple positions on the container body, eliminating the need for multiple separate fasteners while maintaining reliable sealing
2Device complexity
If a single resilient clip fastener is used to simplify the structure, then the device complexity is reduced, but the ease of operation deteriorates because it is difficult to pull open the vacuum sealing cap
Solution Approach 1:
The resilient clip fastener incorporates dynamic characteristics with spring elements that provide automatic engagement and disengagement capabilities, allowing the cap to be securely locked during sealing but easily released when opening by overcoming the resilient force
Solution Approach 2:
An operating member is introduced as an intermediary tool that leverages the resilient clip fastener's elastic properties to amplify user input force, making it easier to overcome the holding force and pull open the cap without requiring direct manual manipulation of the clip itself
3Manufacturing precision
If the inner cap body is held stationary relative to the outer cap body, then the manufacturing precision is improved, but the ease of operation deteriorates because the sealing gasket cannot be easily pressed or released
Solution Approach 1:
The inner cap body is designed to be movable relative to the outer cap body along the sealing surface, allowing dynamic adjustment during sealing and opening operations while maintaining precise alignment through guide structures that constrain movement to the intended path
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 allows for easy and convenient sealing and unsealing of containers by simply pivoting the operating member, ensuring the sealing gasket is pressed or released from the container mouth, enhancing usability and stability of the cap.
Implementation Method 1
a spring element disposed between the inner cap body and the outer cap body for pushing the inner cap body downwardly

AI summary
A vacuum sealing cap for a container includes an outer cap body, an inner cap body movable toward or away from the outer cap body, a sealing gasket compressible by the outer cap body to abut sealingly against the mouth of the container when the inner cap body moves toward the outer cap body, a slide member connected to the inner cap body, and an operating member connected pivotally to the slide member and pivotable between first and second positions, where the operating member pulls upwardly and pushes downwardly the slide member to move the inner cap body upwardly toward and downwardly away from the outer cap body. The sealing gasket is pressed and is not pressed sealingly against the mouth of the container in the first and second positions, respectively.
