Solution Overview

Problem

Current sealed containers have sealing structures that are not integrally formed with the container, making them prone to slipping and loss, and they typically offer only a single sealing function.

Innovation Solution

A container sealing plug with an integrally formed plug body, featuring a sealing part with an elastic sealing ring that presses the inner wall of the container, providing multiple sealing functions and preventing slipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a sealing structure is not integrally formed with the container, then the sealing function is simple and easy to manufacture, but the sealing structure is prone to slipping and loss

Engineering Contradiction:
Improveease of manufactureVSAvoidanti-slip reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The sealing plug is integrally formed with the container body, merging two previously separate components into one unified structure. This integration eliminates the risk of the sealing plug slipping or being lost while maintaining manufacturing simplicity through one-step molding processes.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If a sealing structure is not integrally formed with the container, then the structure is simple and cost-effective, but the sealing function is limited to a single purpose

Engineering Contradiction:
Improvestructural complexityVSAvoidsealing function versatility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The integrally formed sealing plug incorporates multiple sealing surfaces and structures that enable it to perform various sealing functions simultaneously - sealing the container opening, preventing leakage during transport, and providing waterproof protection. This multi-functional design is achieved within a unified structural framework.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If an elastic sealing ring is added to the plug body, then the sealing effect is improved, but the device complexity increases

Engineering Contradiction:
Improvesealing effectVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

An elastic sealing ring is embedded within the integrally formed plug body, utilizing flexible material properties to create an effective seal. The sealing ring's elasticity allows it to deform and conform to the container opening, ensuring a reliable seal while the integral formation keeps the overall structure relatively simple.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The present disclosure provides a container sealing plug. The container sealing plug including a plug body. The plug body is configured to seal a receiving opening of a container. The plug body includes a sealing part. The sealing part is configured to seal the receiving opening of the container. The sealing part is provided with a flexible sealing ring. The sealing ring is configured to press an inner wall that seals the receiving opening of the sealed container. A user can place food, liquid, or other objects into the container through the receiving opening of the container, and then seal the receiving opening of the container through the plug body. When the flexible sealing ring of the plug body is inserted into the receiving opening of the container, the inner wall of the receiving opening presses the flexible sealing ring.
