Tobacco Extract Sheet for Sustained Smoke Taste Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for enhancing tobacco smoke taste in heating-type cigarettes fail to maintain persistence of flavor in mid and late puffs due to rapid transfer of tobacco smoke taste components from added liquids.
Innovation Solution
A tobacco extract sheet produced from a sheet-producing liquid containing tobacco extract solutions and a sheet-forming agent, using solvents like water and ethyl alcohol, is applied to smoking articles to slowly release tobacco smoke taste components, ensuring persistence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If liquid tobacco extract is directly added to smoking material, then tobacco smoke taste is improved in early puffs, but tobacco smoke taste becomes insufficient in mid and late puffs due to rapid transfer of taste components
Solution Approach 1:
The patent changes the physical state of the tobacco extract from liquid to solid sheet form. This parameter change fundamentally alters the release characteristics, allowing the taste components to be released gradually over time rather than transferring rapidly, thus maintaining consistent tobacco smoke taste across early, mid, and late puffs.
Solution Approach 2:
The tobacco extract sheet is formed as a composite material combining tobacco extract with sheet-forming agents. This composite structure enables the extract to be delivered in a controlled, sustained manner rather than all at once, resolving the contradiction between initial taste impact and prolonged taste consistency.
2Quantity of substance
If multiple tobacco extract solutions with different solvents are used, then extraction efficiency and taste components are improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the extraction process by using multiple solvents (water and organic solvent) to extract different components from tobacco. This segmentation allows comprehensive extraction of various taste components while maintaining a systematic, manageable manufacturing process where each extract solution can be prepared and combined in controlled steps.
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 tobacco extract sheet compensates for insufficient tobacco taste in mid and late puffs, improving flavor persistence and smoker satisfaction by gradually releasing taste components.
Implementation Method 1
a sheet-forming agent, wherein the first tobacco extract solution may include water as an extraction solvent, and the second tobacco extract solution may include a material other than water as an extraction solvent

AI summary
A tobacco extract sheet, a method of producing the same, and a smoking article including the same are provided. The tobacco extract sheet according to some embodiments of the present disclosure may be produced from a sheet-producing liquid which includes a first tobacco extract solution, a second tobacco extract solution, and a sheet-forming agent, wherein the first tobacco extract solution may include water as an extraction solvent, and the second tobacco extract solution may include a material other than water as an extraction solvent. The tobacco extract sheet produced in this way may be applied to a smoking article and may significantly improve persistence of a tobacco smoke taste of the smoking article.
