Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing containers and lids have inadequate sealing mechanisms that allow leakage and air intake, leading to trapped product in seams, which affects the integrity of liquid contents and increases waste.

Innovation Solution

A container design incorporating a separate container ring with a u-shaped channel and hook-shaped aperture, along with a lid that engages with the ring to form a liquid-tight seal, eliminating seams and preventing content trapping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If traditional container designs with integrated seams are used, then manufacturing is simpler and device complexity is lower, but product retention is poor and substance loss occurs due to trapped liquid in seams

Engineering Contradiction:

Improveproduct retentionVSAvoidcontainer structure

Core Design Contradiction:

Loss of substanceVSDevice complexity

Solution Approach 1:

The container is divided into two separate components: the container body and the container ring. The ring is attached to the exterior of the container body, creating a distinct separation between the container structure and the sealing mechanism. This segmentation eliminates the traditional seam where the lid met the container body, as the ring provides a separate attachment point for the lid that does not create trapping zones for liquid.

Inventive Principle:

Principle #1Segmentation

2Reliability

If traditional sealing mechanisms are used, then device complexity is lower, but sealing performance is inadequate allowing leakage and air intake

Engineering Contradiction:

Improvesealing performanceVSAvoidsealing structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The container ring acts as an intermediary component between the container body and the lid. It provides a dedicated sealing interface that mediates the connection between these two parts, creating a reliable seal without requiring the lid to directly engage with the container body. The ring includes specific features like the bead and groove that facilitate this intermediary sealing function.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If containers with seams are used, then manufacturing is easier, but product purity is compromised due to trapped content affecting color integrity

Engineering Contradiction:

Improveseam eliminationVSAvoidcontainer production

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

By separating the container into the body and the attached ring, the design eliminates the traditional seam between lid and container body. The ring is positioned on the exterior of the container body and provides a separate engagement point for the lid, ensuring that no seam exists where liquid could become trapped and compromise product purity or color integrity.

Inventive Principle:

Principle #1Segmentation

AI summary

The present disclosure relates generally to containers and container lids. In at least one embodiment, the disclosed containers and container lids provide a liquid-tight seal with the inclusion of a separately attached ring that generally eliminates material-trapping seams. For example, in certain embodiments, a container and a container ring for attaching to the rim of the container is disclosed. In these embodiments, the container ring attaches to the rim of the container such that a liquid-tight vertical seal is formed, thereby reducing or eliminating material-trapping seams.
