Paper Package with Sealable Coating for Absorbent Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent article packaging made of plastic is not eco-friendly and lacks flexibility, making it difficult to handle and open, while alternative non-plastic materials lack the protective and usability benefits of plastic.
Innovation Solution
A package comprising a bag made of paper material with a basis weight between 60 and 100 g/m², featuring a sealed top and peripheral wall with foldable wing portions for easy gripping and handling, and a sealable coating for secure closure, which provides protection against environmental influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plastic packaging material is used, then flexibility and ease of handling are improved, but eco-friendliness deteriorates
Solution Approach 1:
The patent changes the material parameter from plastic to paper with specific basis weight (60-100 g/m²) to achieve eco-friendliness while maintaining handling properties through controlled physical characteristics
Solution Approach 2:
The patent uses composite structure combining paper material with sealable coating to achieve both eco-friendliness and functional properties like sealing capability and moisture protection
2Object-generated harmful factors
If non-plastic packaging material is used, then eco-friendliness is improved, but flexibility and usability deteriorate
Solution Approach 1:
The patent specifies precise parameter ranges for paper basis weight (60-100 g/m²) to optimize the balance between rigidity for protection and flexibility for handling
Solution Approach 2:
The patent applies sealable coating to specific areas (peripheral inner portion) to provide sealing functionality only where needed, maintaining overall paper flexibility while adding localized protective properties
3Strength
If paper material with higher basis weight is used, then protection and stiffness are improved, but ease of gripping deteriorates
Solution Approach 1:
The patent optimizes paper basis weight to a specific range (60-100 g/m²) that provides sufficient structural strength while maintaining adequate flexibility for gripping
Solution Approach 2:
The patent divides the package structure into peripheral wall and wing portions, creating distinct functional zones where wing portions provide gripping surfaces while the peripheral wall provides structural protection
4Object-affected harmful factors
If the bag is made rigid for protection, then protection against environmental influences is improved, but ease of opening deteriorates
Solution Approach 1:
The patent segments the bag structure into a rigid peripheral wall for protection and flexible wing portions for easy opening, allowing different parts to serve different functional requirements
Solution Approach 2:
The patent creates a dynamic structure where the wing portions can be folded and unfolded, transitioning from a compact protected state to an open accessible state, facilitating easy opening while maintaining protection

AI summary
A package (1000) comprising a bag (100) and a stack of absorbent articles (200) having a substantially rectangular shape, wherein the stack of absorbent articles is arranged in the bag. The bag (100) is made of a paper material having a basis weight between 60 and 100 g/m2 measured according to the ISO 536 standard, wherein the bag (100) has a closed bottom (110), a closed top (120), and a peripheral wall (130) between said bottom and said top. The bag is provided at least on an inner surface of the bag near the top, with a sealable coating (140) wherein the closed top (120) is realized by a sealed portion (145) of said sealable coating (140).
