Scented Tissue Box Insert With Heat-Activated Gel Fragrance Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scented paper tissue containers face issues with high production costs due to low yield of perfume-containing microcapsules and significant production-switching losses when switching between scented and unscented products, and they struggle to deliver strong, refreshing scents like menthol or citrus-based fragrances.
Innovation Solution
A paper tissue container design featuring a scented sheet member with gelatin gel and perfume-permeating holes, where the gelatin gel is solated by heating to release a strong scent, and the sheet member is affixed to the inner surface of the container, allowing users to intensify the fragrance by applying a physical stimulus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perfume-containing microcapsules are applied directly to paper tissues, then the paper tissues can be scented, but the yield of microcapsules is low and production cost is very high
Solution Approach 1:
The invention extracts the perfume from the direct application process and places it in a separate scented sheet member that contains the perfume reservoir. This separates the perfume storage function from the paper tissue, allowing the paper tissue production to proceed without microcapsule application equipment, thereby reducing production cost and switching loss while maintaining scented effectiveness through the scented sheet member's perfume release.
Solution Approach 2:
The scented sheet member acts as an intermediary between the perfume and the paper tissues. Instead of applying microcapsules directly to the paper tissues, the perfume is stored in the scented sheet member and released to scent the tissues indirectly, improving both production efficiency and cost-effectiveness.
2Reliability
If perfume-containing microcapsules are applied to paper tissues, then the paper tissues are scented, but a large production-switching loss occurs when switching between scented and unscented production
Solution Approach 1:
The scented function is extracted from the paper tissue production line and placed in a separate scented sheet member that is inserted into the containing box. This allows the paper tissue production to remain unscented and production-ready, while the scented sheet member can be independently manufactured and inserted later, eliminating the need to clean equipment when switching between scented and unscented production.
Solution Approach 2:
The product is segmented into separate components: unscented paper tissues and a separate scented sheet member. This segmentation allows independent production of each component, enabling quick switching between scented and unscented paper tissue production without affecting the other, thereby reducing production-switching loss.
3Duration of action of stationary object
If a slit film with perfume is used, then the perfume volatilizes over a long time, but the scent strength cannot be adjusted and strong refreshing sensation cannot be achieved
Solution Approach 1:
The scented sheet member incorporates a gel layer that can transition between gel and sol states. When the gel transitions to sol (through heating or other stimuli), the perfume release rate increases dramatically, providing strong refreshing sensation. This dynamic state change allows the user to adjust scent strength on demand while maintaining long-duration release capability in the gel state.
Solution Approach 2:
The invention changes the physical state parameter of the gel layer (from gel to sol) to control perfume release rate. In gel state, perfume releases slowly over long duration; in sol state, perfume releases rapidly for strong refreshing sensation. This parameter change enables both long-duration release and adjustable scent strength.
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
This design eliminates production-switching losses, enhances scent strength on demand, and provides a cost-effective solution for producing scented paper tissues with a strong, refreshing aroma.
Implementation Method 1
the gelatin gel solates at a temperature in the range of 30 to 40°C
Implementation Method 2
a large number of perfume-permeating holes are formed in at least one of the film sheets

AI summary
A scented sheet member, in which a gelatin gel including at least one of a perfume and a perfume-containing microcapsule is enclosed in a space between film sheets in at least one of which a perfume-permeating hole is formed, is affixed to an inner surface of an upper surface of the containing box so that the at least one of the film sheets having the micropore faces a stack of paper tissues. This can provide a scented paper tissue container that can strengthen a scent when necessary.
