Embossed Label Substrate With Flat Liner for Reliable Dispensing

Solution Overview

Problem

Current embossing methods for labels result in dispensing issues during high-speed applications, adhesive weakness at embossed edges, and aesthetic degradation in moist environments, particularly for wine and spirit labels.

Innovation Solution

The solution involves creating labels with a non-embossed liner and selectively embossing the substrate, using thermoforming to enhance emboss retention, and employing styrene-based films for moisture resistance and premium aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the entire label construction (substrate, adhesive, and liner) is embossed using traditional methods, then the embossing process is simple and consistent, but the label experiences dispensing issues during high-speed application, adhesive weakness at embossed edges, and aesthetic degradation in moist environments

Engineering Contradiction:

Improveembossing process consistencyVSAvoidlabel dispensing reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent applies local quality by differentiating the embossing treatment across different layers: the substrate receives full embossing to achieve the desired aesthetic effect, while the liner remains unembossed to maintain a flat dispensing surface. This selective embossing resolves the contradiction by allowing the substrate to have premium appearance while the liner ensures reliable high-speed dispensing without misapplication issues.

Inventive Principle:

Principle #3Local quality

2Shape

If the entire label construction is embossed, then the embossed appearance is achieved across all layers, but the adhesive strength decreases at embossed edges

Engineering Contradiction:

Improveembossed appearanceVSAvoidadhesive strength

Core Design Contradiction:

ShapeVSStrength

Solution Approach 1:

The patent applies local quality by differentiating the embossing treatment across different layers: the substrate receives full embossing to achieve the desired aesthetic effect, while the liner remains unembossed to maintain a flat dispensing surface. This selective embossing resolves the contradiction by allowing the substrate to have premium appearance while the liner ensures reliable high-speed dispensing without misapplication issues.

3Shape

If uncoated paper is used for wine and spirit labels, then a premium aesthetic look is achieved, but the label experiences aesthetic degradation (graying, bubbling, wrinkling) in moist environments

Engineering Contradiction:

Improvepremium aesthetic lookVSAvoidmoisture resistance

Core Design Contradiction:

ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent applies composite materials by combining a synthetic film substrate (providing moisture resistance and structural integrity) with a coating layer (providing premium aesthetic appearance similar to uncoated paper). This composite structure resolves the contradiction by integrating the moisture barrier properties of synthetic materials with the aesthetic qualities of paper-like surfaces, preventing graying, bubbling, and wrinkling in humid wine storage environments.

AI summary

A label as shown and described herein. The label may include a label substrate, an adhesive adjacent the substrate, and a liner adjacent the adhesive, such that the adhesive is disposed between the label substrate and the liner, and wherein the label substrate is embossed or debossed, and the liner is not embossed or debossed.
