Solution Overview

Problem

Existing open-end containers with lids fail to effectively reseal after initial use, leading to spoilage of contents like paint and chemicals, as traditional seals do not provide sufficient surface area contact and are not resilient enough to maintain a tight seal against varying container surfaces.

Innovation Solution

The design incorporates a lid with a seal engagement surface featuring multiple ramps, ledges, or teeth that increase the surface area for a resilient seal to compress against, along with a second seal ring at the rim, and integrated grips for easier handling, allowing for a secure screw-on or press-fit lid that forms an airtight or watertight seal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional seal is used on a smooth container surface, then the seal structure is simple, but the seal effectiveness is insufficient due to limited surface area contact

Engineering Contradiction:
Improveseal effectivenessVSAvoidseal structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The seal engagement surface is segmented into multiple ramps, ledges, or teeth that create distinct contact zones for the seal. This segmentation increases the total surface area contact between the seal and container, improving seal effectiveness without requiring a completely complex seal structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The seal engagement surface extends in multiple dimensions with ramps and ledges that create vertical and horizontal contact surfaces. This dimensional expansion allows the seal to engage with the container over a larger area, transforming a simple single-surface contact into a multi-surface engagement system.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If a non-resilient seal material is used, then the seal structure is simple, but the seal cannot maintain tight contact against varying container surfaces

Engineering Contradiction:
Improveseal tightnessVSAvoidseal material complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The seal material parameters are changed from non-resilient to resilient properties, allowing the seal to deform and conform to the container surface variations. This parameter change enables the seal to maintain consistent contact pressure and tightness across uneven surfaces without modifying the overall seal structure.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This configuration enhances the seal's effectiveness by increasing the contact surface area and using resilient materials, ensuring the contents remain fresh for later use by maintaining a tight seal, and the grips provide a comfortable and secure mechanism for opening and closing the lid.

AI summary

The open ended container with resealable lid combination has a seal ring which cooperates with a seal engagement surface to provide a resealable construction to provide at least one of an airtight and watertight configuration after the lid has initially been removed from the container and re-applied. The seal engagement surface preferably provides at least two ramps and the seal ring deforms along at least one, if not both of the ramps.
