Interdental Cleaning Tool Perfume Layer Emulsion Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interdental cleaning tools with perfume applications face challenges in maintaining uniformity and longevity of flavor, often resulting in insufficient scent and cool sensation due to volatility and poor workability in production.
Innovation Solution
An interdental cleaning tool with a polystyrene elastomer cleaning part coated with a perfume layer containing glycerin fatty acid ester, oil-soluble perfume, and gum arabic or starch octenylsuccinate, applied through a stable emulsion and dried to form a durable, long-lasting flavor layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a powdery aroma component is used in a covering film, then the cleaning part can be covered with a perfume layer, but the coatability and cool sensation are easily influenced by concentration or particle size, making it difficult to maintain uniformity of products
Solution Approach 1:
The patent changes the physical state of the perfume from powdery to liquid form, and changes the application method from direct coating to emulsion-based coating. This parameter change eliminates the influence of particle size and concentration variations, enabling consistent coatability and product uniformity.
Solution Approach 2:
The patent introduces an emulsion as an intermediary medium to apply the liquid perfume. The emulsion contains the perfume and auxiliary substances that improve coatability, acting as a mediator between the perfume and the cleaning part surface, thereby ensuring uniform application and consistent cool sensation.
2Duration of action of stationary object
If a liquid perfume is kneaded into the synthetic resin cleaning part, then the perfume can be held in the cleaning part, but strong smell is emitted during production requiring deodorization steps, and the perfume quickly volatilizes after productization
Solution Approach 1:
The patent extracts the perfume application process from the bulk resin manufacturing and applies it only to the surface of the cleaning part through emulsion coating. This separates the perfume-containing portion from the main resin body, eliminating strong smells during production while maintaining long-term retention on the surface.
Solution Approach 2:
The patent applies the perfume emulsion to the cleaning part surface before final product completion. This preliminary application allows the perfume to be properly fixed on the surface, ensuring long-term retention without requiring subsequent deodorization steps.
3Quantity of substance
If a liquid perfume is kneaded into the synthetic resin cleaning part, then the perfume can be held in the cleaning part, but the scent can be felt when smelled, but the scent can hardly be felt when used in the oral cavity, and thus the taste or cool sensation is insufficiently obtained
Solution Approach 1:
The patent concentrates the perfume in a thin emulsion layer on the surface of the cleaning part rather than distributing it throughout the bulk resin. This local concentration ensures that when the cleaning part contacts oral tissues, the perfume is immediately available to provide strong cool sensation and taste, while the thin layer allows rapid transfer of the cooling effect.
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
The solution provides a consistent and prolonged flavor experience while ensuring softness and safety during use, improving product uniformity and reducing production costs by stabilizing the perfume layer.
Implementation Method 1
a coating step in which a cleaning part surface of the cleaning body is coated with a treatment liquid in which a flavor component and the like are stably emulsified (hereinafter referred simply to as an "emulsion") to form a perfume layer
Implementation Method 2
a drying step in which the solvent of the emulsion coated is vaporized and removed

AI summary
An interdental cleaning tool comprising: a handle base formed of a synthetic resin; and a cleaning part disposed on an end portion of the handle base, wherein a cleaning body substantially formed of a polystyrene elastomer in the cleaning part is covered with a perfume layer, and the perfume layer contains a glycerine fatty acid ester, an oil-soluble perfume as a flavor component, and gum arabic and/or starch octenylsuccinate as a water-soluble covering base.
