Elastic Valve Cover Bung Plug Closure Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of valve covers on bung plug closures requires significant effort due to the need for welding, which complicates the production process and increases the risk of damage to the valve body.
Innovation Solution
A bung plug closure design featuring an elastically deformable disk valve cover with a diameter smaller than the receiving space, secured by the connection between the seal cap and bung plug, eliminating the need for additional installation measures and ensuring the valve cover remains positioned even when the seal cap is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve cover is installed to protect the valve body, then protection against damage and pollution is improved, but installation complexity and production effort increase due to welding requirements
Solution Approach 1:
The patent replaces the welding-based mechanical connection system with an elastic deformation-based retention system. The valve cover is made of elastically deformable material that can be inserted through the receiving space and retained by the locking protrusion, eliminating the need for welding operations while maintaining secure attachment and protection functionality.
Solution Approach 2:
The patent changes the physical state and mechanical properties of the valve cover by using elastically deformable material instead of rigid welded material. This parameter change allows the valve cover to be installed by elastic deformation through the receiving space and retained by the locking protrusion, significantly reducing installation complexity while maintaining protection reliability.
2Strength
If welding is used to connect the valve cover to the bung plug, then connection strength is improved, but production time and manufacturing effort increase
Solution Approach 1:
The patent substitutes the welding process with a mechanical elastic retention system. The valve cover's elastic deformability allows it to be inserted and retained by the locking protrusion without thermal processing, dramatically reducing production time while maintaining sufficient connection strength through the elastic locking mechanism.
Solution Approach 2:
The patent segments the valve cover into a modular component that can be independently manufactured and installed. The elastic deformable valve cover with its specific geometric configuration allows for separate production and assembly, eliminating the need for time-consuming welding operations and improving overall production efficiency.
3Ease of operation
If the valve cover diameter is reduced to fit through the receiving space, then ease of installation is improved, but coverage and protection effectiveness may be compromised
Solution Approach 1:
The patent utilizes the elastic deformability parameter of the valve cover material to resolve the size contradiction. The valve cover is designed with a diameter suitable for protection coverage, and its elastic properties allow it to be temporarily deformed to pass through the smaller receiving space during installation, then return to its full protective coverage dimension when installed.
Solution Approach 2:
The patent introduces dynamic behavior to the valve cover installation process through elastic deformation. The valve cover transitions from its installed protective state to a compressed installation state as it passes through the receiving space, then returns to its protective configuration upon installation, enabling both easy installation and effective protection.

AI summary
A bung plug closure for bung-hole containers includes a bung plug for being placed in a bung neck and a seal cap for closing a plug recess formed in the bung plug, the plug recess having a space for receiving a dimensionally elastic engaging body formed on the seal cap and having a radial locking protrusion, a valve disposed in a bottom of the plug recess, the valve having a valve body disposed in a valve opening of a bottom recess, the valve body including a valve cover connected to the bung plug, the valve cover being an elastically deformable disk, the valve cover connected to the bung plug such that a circumferential edge of the valve cover, which protrudes radially outward over matching locking elements for interlocking with the locking protrusion, is received between the locking protrusion of the engaging body and a recess edge of the bottom recess.
