Paper Tampon Applicator Coating for Petroleum Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tampon applicators, particularly those made from thermoplastics and paperboard, still rely on petroleum-derived materials for components like binders, adhesives, and coatings, which raises environmental concerns and limits sustainability.
Innovation Solution
The development of a tampon applicator made from paper or cardboard, with a coating that is not predominantly derived from petroleum, such as a natural wax, to reduce the use of petroleum-based materials while maintaining functional performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If thermoplastics are used to make tampon applicators, then manufacturing efficiency and functional features are improved, but petroleum use and environmental impact increase
Solution Approach 1:
The patent changes the material composition parameter by substituting petroleum-based thermoplastics with paperboard or cardboard materials, while adjusting coating parameters (using non-petroleum coatings like beeswax, carnauba wax, or vegetable oil-based coatings) to maintain the necessary functional properties for applicator performance
Solution Approach 2:
The patent creates a composite structure combining paperboard/cardboard base material with non-petroleum-derived coatings (such as beeswax, carnauba wax, or vegetable oil-based coatings), achieving both reduced petroleum content and maintained functional performance
2Object-generated harmful factors
If paperboard or cardboard is used to make tampon applicators, then petroleum use is reduced, but functional performance and smooth operation may deteriorate
Solution Approach 1:
The patent modifies the surface parameters of paperboard applicators by applying non-petroleum coatings (beeswax, carnauba wax, vegetable oil-based coatings) to achieve appropriate friction coefficients and surface smoothness, ensuring reliable functional performance
Solution Approach 2:
The patent introduces non-petroleum coatings (beeswax, carnauba wax, vegetable oil-based coatings) as intermediary layers between the paperboard substrate and the environment, mediating the interaction to provide necessary lubrication and surface properties without using petroleum-based materials
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 solution effectively reduces the environmental impact of tampon applicators by minimizing petroleum use, while ensuring the applicator functions smoothly and is comfortable to use, as demonstrated by appropriate Relative Sliding Resistance Coefficients (CSRs) and Gripping Slip Resistance Coefficients (CGSRs).
Implementation Method 1
The coating on the applicator is configured to reduce relative sliding resistance between components of the applicator
Implementation Method 2
The textured surface is configured to increase gripping slip resistance of the applicator

AI summary
A tampon product including an applicator with a hollow barrel portion and an ejection plunger within the barrel portion, is disclosed. One or both of the barrel portion and the ejection plunger may have a cylindrical form and be formed of a paper, and have a coating applied to the paper, wherein the coating is not predominately constituted by a material derived from petroleum. The coated paper barrel portion and/or ejection plunger may be manufactured to as to exhibit a static Relative Sliding Resistance Coefficient (CSR) no greater than 0.250 and/or a kinetic CSR no greater than 0.210, for purposes of smooth manufacturing. In combination or alternatively, the coated paper barrel portion and/or ejection plunger may be manufactured to as to exhibit a static Gripping Slip Resistance Coefficient (CGSR) no less than 0.190 and/or a kinetic CGSR no less than 0.170, for purposes of consumer satisfaction.
