Solution Overview
Problem
Fragrance and flavoring substances in plastic packaging interact with the plastic, leading to issues like loss of fragrance, deformation, and discoloration, particularly exacerbated by surface-active compounds, resulting in damaged packaging and altered olfactory impressions.
Innovation Solution
A composition comprising specific hydrocarbon terpenes, methyl anthranilate derivatives, phenolic derivatives, cyclic monoterpenes, and other compounds, with restricted amounts to minimize interaction with PE, PP, and PET packaging, reducing detrimental effects such as deformation and color changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fragrance and flavoring substances are contained in plastic packaging, then transport and handling are enabled, but interaction occurs leading to loss of fragrance, deformation, and discoloration
Solution Approach 1:
The patent introduces specific chemical compounds (Group A: hydrocarbon terpenes with oxygen percentage of 0, methyl anthranilate derivatives, phenolic derivatives; Group B: cyclic monoterpenes, methoxybenzene derivatives, 2-hydroxybenzoic acid derivatives, benzoate derivatives, oxomethylbenzene derivatives, 3-oxopropylbenzene derivatives, cyclohex-3-ene-1-carbaldehyde derivatives, styrene derivatives, acetals, ethers, heterocyclic compounds, ketones, lactones, nitriles; Group C: additional fragrance/flavoring substances) as intermediary substances that modify the interaction between the fragrance composition and plastic packaging. These compounds are selected and controlled at specific concentrations (Group A: ≤0.5 wt%, Group B: <10 wt%, Group C: ≤20 wt%) to prevent direct harmful interaction while enabling safe containment and transport
Solution Approach 2:
The patent applies parameter changes by precisely controlling the concentration levels of different chemical groups in the composition. By limiting Group A compounds to 0.5 wt% or less, Group B compounds to less than 10 wt%, and Group C compounds to 20 wt% or less, the patent modifies the chemical parameters of the composition to reduce diffusion into plastic and prevent detrimental interactions, thereby maintaining both transport capability and product integrity
2Reliability
If surface-active compounds are added to fragrance compositions, then olfactory impression is enhanced, but damage to plastic containers is worsened
Solution Approach 1:
The patent controls the concentration of surface-active compounds and other ingredients within specific ranges (Group A: ≤0.5 wt%, Group B: <10 wt%, Group C: ≤20 wt%) to modify their interaction with plastic. At these controlled levels, surface-active compounds maintain their function of enhancing olfactory impression while their harmful effect on plastic is reduced to acceptable levels, resolving the contradiction between performance and packaging integrity
3Strength
If fragrance substances diffuse into plastic, then packaging is damaged, but valuable fragrance substances are lost
Solution Approach 1:
The patent uses specifically selected compounds in Groups A, B, and C as intermediary substances that create a protective chemical environment. These compounds interact with both the fragrance substances and the plastic packaging, reducing the diffusion rate and preventing direct contact between fragrance molecules and plastic polymers, thereby simultaneously preserving packaging strength and retaining fragrance substances
Solution Approach 2:
By controlling the concentration parameters of different chemical groups (Group A: ≤0.5 wt%, Group B: <10 wt%, Group C: ≤20 wt%), the patent modifies the diffusion characteristics of the composition. This parameter control reduces the driving force for fragrance substance diffusion into plastic while maintaining packaging integrity, thus preventing both packaging damage and fragrance loss
