Solution Overview

Problem

Existing container closure devices lack an identification or marking element that allows for easy classification, sorting, or assignment of containers based on type, class, size, manufacturer, or processor, even when the container is closed.

Innovation Solution

The container-side holding elements are designed as identification elements, such as lettering, numbers, or graphic configurations, which are visible and protrude from the container's mouth area, enabling easy assignment and sorting, and the locking part is made transparent to maintain visibility when closed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the container is closed with a closure device, then the container opening is sealed, but the container cannot be identified or sorted without opening it

Engineering Contradiction:
Improvecontainer sealingVSAvoidcontainer identification
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent combines the closure function and identification function into a single integrated system. The container-side retaining elements serve dual purposes: they mechanically engage with the closure device to seal the container, and simultaneously display identification information (letters, numbers, graphics) that remains visible when the container is closed. This eliminates the need for separate identification markings that would require opening the container to access.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The retaining elements on the container are designed to perform multiple functions: providing mechanical retention for the closure device and displaying identification information. The transparency of the locking element further enables the identification elements to serve as both structural components and information display elements, allowing the same component to fulfill both sealing and identification roles simultaneously.

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

2Adaptability or versatility

If identification elements are added to the container, then container sorting is enabled, but the closure device structure becomes more complex

Engineering Contradiction:
Improvecontainer sorting capabilityVSAvoidclosure device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the identification elements with the existing retaining elements of the closure device. Rather than adding separate identification components, the design incorporates letters, numbers, or graphics directly into the container-side retaining elements. This integration approach enables container identification and sorting while utilizing the existing structural components of the closure device, thereby avoiding significant increases in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If the locking element is made transparent to maintain visibility of identification elements, then container identification remains visible when closed, but the locking element material options are limited

Engineering Contradiction:
Improveidentification visibilityVSAvoidlocking element material selection
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The patent applies local quality by making only the portion of the locking element that interacts with the container-side retaining elements transparent. This localized transparency ensures that the identification elements remain visible when the container is closed, while other portions of the locking element can be made from different materials with different properties, thus broadening material selection possibilities.

Inventive Principle:
Principle #3Local quality
