Solution Overview
Problem
Film-packaged tissues struggle to maintain their shape when collectively packaged, making them difficult to stack and sell in large quantities due to their flexible nature, unlike box tissues which have rigidity.
Innovation Solution
A pop-up type tissue paper bundle is formed by folding and stacking tissue papers with outer folded sides inward, packaged in a flexible resinous film with air vents on the short side surfaces, and subjected to gusset packaging to maintain shape and improve rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If film-packaged tissue is used instead of box tissue, then packaging material amount is reduced and transportation cost is reduced, but shape maintenance capability deteriorates
Solution Approach 1:
The patent uses a flexible packaging film instead of a rigid box to package the tissue bundle. The film is formed into a bag shape that conforms to the tissue bundle, providing protection while maintaining flexibility. This resolves the contradiction by achieving adequate packaging protection with minimal material while allowing the package to maintain its shape through the film's structural design rather than rigidity.
2Productivity
If film-packaged tissue is collectively packaged in a piled state, then sales volume efficiency is improved, but shape maintenance capability deteriorates
Solution Approach 1:
The patent divides the collective package into multiple individual film-packaged tissue bundles, each maintaining its own shape. These segmented units are then arranged and packaged together in a larger pile package. The segmentation allows each unit to maintain its shape independently while the collective arrangement achieves efficient stacking and display in retail environments.
Solution Approach 2:
The patent introduces air vents in specific orientations and uses three-dimensional arrangement of multiple tissue bundles within the collective package. By considering spatial dimensions and orientation of air vents facing different directions, the package maintains stability and shape when piled, enabling efficient vertical stacking in retail while preserving individual bundle integrity.
3Reliability
If air vents are formed in packaging film, then air discharge function is improved, but packaging film integrity deteriorates
Solution Approach 1:
The patent incorporates air vents as controlled porous openings in the packaging film. These vents are strategically positioned and sized to allow air discharge while maintaining sufficient film integrity. The vents are formed as discrete openings rather than making the entire film porous, balancing the need for air discharge with maintaining packaging strength and protection.
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 solution allows for effective collective packaging and maintaining the shape of film-packaged tissues, enhancing their stability and portability, enabling efficient large-scale sales by reducing bulk and improving standing stability when stacked.
Implementation Method 1
thermally bonding the packaging film at a position where the air vent remains

AI summary
A tissue paper package not prone to losing shape. Film-packaged tissue paper comprising a pop-up type substantially cuboid bundle of tissue paper packaged with a flexible resin packaging film, and characterized in that air vents for providing communication between the inside and the outside of the package are formed at positions on the packaging film facing short-side surfaces of the bundle of tissue paper where no folded edges are arranged.
