Solution Overview

Problem

Existing container lids face difficulties in forming an air-tight and water-tight seal while being easy to open and close, and they are often complex and costly, with latches being prone to breakage and difficult to disassemble for cleaning.

Innovation Solution

A container lid design featuring a handle assembly with a neck member and locking mechanism that allows for easy sealing and unsealing, utilizing a sealing ring that biases against the container wall for a tight seal and can be easily disassembled for cleaning, with a simplified structure and internal threads for secure engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a friction-fit lid is used to form an air-tight and water-tight seal, then sealing performance is improved, but the ease of opening and closing deteriorates due to tight friction

Engineering Contradiction:
Improvesealing performanceVSAvoidease of opening and closing
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The lid is divided into two main segments: a stationary lid body that remains on the container, and a removable base plate that can be easily detached. The sealing ring is integrated into the lid body, ensuring that the sealing function remains while the base plate can be removed without overcoming friction from a tight seal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing function is extracted from the removable portion and fixed into the lid body. The base plate is taken out as a separate, lightweight component that does not need to overcome friction to maintain sealing, as the sealing ring remains on the stationary lid body.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If latches are used to seal a container, then sealing capability is achieved, but device complexity increases and reliability decreases due to easy breakage

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

Solution Approach 1:

The complex latch mechanism is completely removed and replaced with a simple friction-based retention system. The base plate has a peripheral edge that frictionally engages with the lid body's receiving chamber, eliminating the need for latches while maintaining sealing capability through the integrated sealing ring.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The design uses simple, inexpensive components without fragile moving parts. The friction-fit retention system uses basic geometric shapes and material friction rather than precision-machined latch components, reducing complexity and breakage risk.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If existing lid structures are used, then sealing function is provided, but ease of manufacture deteriorates due to difficulty in disassembly for cleaning

Engineering Contradiction:
Improvesealing functionVSAvoidease of disassembly for cleaning
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The lid is segmented into a stationary lid body containing the sealing ring and a removable base plate. This segmentation allows the base plate to be easily detached for cleaning while the sealing ring remains on the lid body, maintaining sealing function while enabling easy maintenance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base plate is extracted as a separate removable component that can be easily taken out for cleaning. The sealing ring is extracted from the removable portion and fixed into the lid body, ensuring sealing function is maintained while the removable base plate can be freely cleaned without disassembling sealing components.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The present invention relates to a lid for a container (1), which lid is capable of sealing and being removed from the container through simply rotating a handle (301) mounted on the lid. The lid comprises two parts to provide the ease of cleaning of the lid. The two parts of the lid can be conveniently disassembled by pushing at least one locking plate (4) provided on the lid, and can be easily re-assembled. The present invention also provides a sealing ring (7) which provides better sealing effect and easier mounting.
