Plug-Integrating Container With Welded Plug And Nested Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage containers require a complex process for connecting and disconnecting caps and plugs, which can lead to joint damage from external impacts and leakage issues during liquid extraction or filling.
Innovation Solution
A plug-integrating container design featuring a container body with external threads, a plug with a groove for socket connection, and a cap with internal threads, where the plug is heat-bonded or welded to the container body and accommodated inside the cap for protection and sealing, allowing easy connection to a socket while preventing external impact damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cap is removed and replaced with a special cap having piping installed, then the liquid can be extracted, but the process becomes complex and time-consuming
Solution Approach 1:
The invention merges the cap and plug into a single integrated component called a 'plug-integrating cap'. The plug is permanently attached to the cap body through heat bonding or welding, eliminating the need for separate cap removal and replacement operations. This single component can be directly connected to piping sockets for liquid extraction, significantly simplifying the process while maintaining productivity.
Solution Approach 2:
The plug is pre-attached to the cap during manufacturing through heat bonding or welding, creating a ready-to-use plug-integrating cap. This preliminary action eliminates the need for on-site plug attachment and piping connection operations, reducing both process complexity and time required for liquid extraction.
2Ease of operation
If the plug is externally connected to the container, then connection to piping is simplified, but the joint is vulnerable to external impact damage
Solution Approach 1:
The plug is nested inside the cap body, with the cap serving as a protective outer shell. This nested configuration protects the plug-joint from external impacts while maintaining ease of operation, as the entire plug-integrating cap can be handled and connected to piping sockets as a single robust unit.
Solution Approach 2:
The cap body acts as a cushioning protective layer around the plug-joint before any external impact occurs. This beforehand protection ensures that the critical joint between plug and container body is shielded from damage during transportation and handling, while still allowing easy connection to piping through the cap's external interface.
3Strength
If the plug is heat-bonded or welded to the container body, then the joint strength is improved, but the complexity of assembly increases
Solution Approach 1:
The plug and cap are merged into a single integrated component through heat bonding or welding during manufacturing. This merging creates a strong, reliable joint that can withstand external impacts, while the integrated design simplifies subsequent assembly operations compared to separate plug and cap components.
Solution Approach 2:
The heat bonding or welding of the plug to the cap is performed as a preliminary action during cap manufacturing, creating a pre-assembled plug-integrating cap. This preliminary bonding simplifies final assembly at the use site, as the plug is already securely attached and ready for installation without requiring complex on-site joining operations.

AI summary
The plug-integrating container includes a container body having an opening part having external threads formed on its outer circumferential surface, a plug having a locking groove for connection to a socket, and a cap having formed on its inner circumferential surface internal threads fastened to the external threads. In the plug-integrating container, the container body has an open end formed at an axis directional end of the opening part, the plug has an annular part formed at an axis directional end and having the same diameter as that of the open end, the open end and the annular part are joined together by welding as they are butted against each other, and the opening part and the plug are accommodated inside the cap when the external threads and the internal threads are fastened together.
