Solution Overview

Problem

Existing aroma delivery systems for consumer products, particularly beverages and personal care items, fail to effectively retain and release polar and volatile aroma compounds, often resulting in unsatisfactory aroma perception and appearance issues, and are not suitable for edible products due to limitations in retaining aroma for the life of the package and incorporating tamper-resistant features.

Innovation Solution

A water-resistant aroma delivery system using a polymeric matrix of natural wax to entrap aroma compounds, which can be covered by a secondary protective film, applied under the container closure to release the aroma when breached, allowing for consistent and representative aroma release from volatile, hydrophobic, and hydrophilic compounds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If aroma compounds are added to beverages to enhance aroma, then the aroma perception is improved, but the taste of the beverage is adversely affected

Engineering Contradiction:
Improvearoma compound concentrationVSAvoidtaste degradation
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The invention separates the aroma delivery function from the beverage composition by using a physical delivery system (container closure with aroma release mechanism) rather than chemically incorporating aroma compounds into the beverage. This segmentation allows aroma enhancement without direct contact between aroma compounds and beverage taste components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container closure acts as an intermediary device that delivers aroma to the consumer without requiring the aroma compounds to be mixed into the beverage. The aroma release mechanism mediates between the aroma source and the consumer's sensory experience, avoiding direct interaction between aroma compounds and beverage taste.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If overwraps or scratch-and-sniff strips are used to deliver aroma, then aroma release is achieved, but the appearance becomes unsatisfactory and aroma retention is compromised

Engineering Contradiction:
Improvearoma deliveryVSAvoidaroma retention and appearance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention merges the aroma delivery system with the container closure itself, making the closure serve dual functions: sealing the container and delivering aroma. This integration eliminates separate aroma delivery components (like overwraps or strips) that compromise appearance and reliability, while maintaining effective aroma release.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The container closure is designed to perform multiple functions simultaneously: it provides tamper-evident sealing, product protection, and aroma delivery. This multi-functionality eliminates the need for separate aroma delivery mechanisms that would compromise appearance or aroma retention reliability.

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

3Ease of operation

If aroma is released from the outside of the container, then aroma delivery is achieved, but the aroma does not emanate from the vicinity of the product

Engineering Contradiction:
Improvearoma releaseVSAvoidaroma source accuracy
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The invention positions the aroma release mechanism in the headspace dimension above the product, allowing aroma to emanate from the vicinity of the product rather than from the outside surface. This spatial repositioning maintains the association between aroma source and product while enabling effective aroma delivery.

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

Applied Scientific Principles
