Paper Base Ink Storage Pipe with Resin Inner Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink storage pipes for writing utensils face challenges in durability, heat resistance, and maintaining performance when substituting traditional plastics with biodegradable resins or paper-based materials, while also ensuring visibility of residual ink amounts.
Innovation Solution
A multi-layered ink storage pipe structure utilizing a paper base material for the base layer and a biodegradable resin or specific resins like acrylic, polystyrene, or fluorine for the inner layer, with optional additional layers for enhanced properties, formed through lamination and winding processes to create a durable and environment-friendly solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If biodegradable resins are used for the ink storage pipe, then environmental friendliness is improved, but durability and heat resistance deteriorate
Solution Approach 1:
The invention uses a composite structure consisting of a paper base material layer and a biodegradable resin layer. The paper base material provides structural strength and durability, while the biodegradable resin layer provides environmental friendliness and ink compatibility. This composite approach allows the ink storage pipe to maintain mechanical integrity while being environmentally degradable.
2Object-affected harmful factors
If paper base material is used for the ink storage pipe, then environmental friendliness is improved, but visibility of residual ink deteriorates
Solution Approach 1:
The invention applies local quality by making only the necessary portion (the layer in contact with ink) biodegradable while keeping the structural layer (paper base material) opaque for strength. The biodegradable resin layer is positioned specifically where ink contact occurs, providing environmental benefits without compromising the overall structural integrity and visibility functions of the pipe.
3Object-affected harmful factors
If biodegradable resins are used for the ink storage pipe, then environmental friendliness is improved, but strength decreases with time
Solution Approach 1:
The composite structure combines the time-stable paper base material with the biodegradable resin layer. The paper base material maintains structural strength over time, while the biodegradable resin provides the necessary ink compatibility and environmental degradability. This division of functional roles resolves the contradiction between long-term strength maintenance and environmental friendliness.

AI summary
Provided is an environment-friendly ink storage pipe for writing utensils with reduced use of plastics by using a paper base material instead of plastics such as a polypropylene that used to form the ink storage pipe. The ink storage pipe includes an at least two-layer structure of an inner layer in contact with ink and a base layer, the base layer being formed of a paper base material and the inner layer being formed of a resin. The resin is preferably an acrylic resin, polystyrene, a fluorine resin, silicone or a mixture thereof.
