Pocket Tissue Package with Pre-Folded Structure to Reduce Tearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pocket tissues require effort to convert from a packed state to a usable folded-in-half shape, and they may tear easily when taken out due to low strength, especially when containing moisturizing components.
Innovation Solution
A pocket tissue package design where each paper tissue is folded at multiple positions, including a first fold bisecting the tissue, a second fold in the longitudinal direction, and third folds perpendicular to the first, allowing easy extraction in a folded-in-half state with alternating thin and thick portions to enhance strength and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a paper tissue is folded in half along the transverse direction after being folded multiple times along the longitudinal direction (conventional folding), then the tissue can be compactly packed, but it requires effort to spread and refold the tissue to achieve a usable folded-in-half shape
Solution Approach 1:
The paper tissue is pre-folded in half along the transverse direction before being folded along the longitudinal direction during packing. This preliminary folding action ensures that when the tissue is taken out, it is already in the desired folded-in-half shape for use, eliminating the need for the user to spread and refold it.
2Volume of moving object
If a paper tissue is folded multiple times along the longitudinal direction (conventional folding), then the tissue can be compactly packed, but the tissue may be torn along the fold portion when taken out due to low strength
Solution Approach 1:
The folding sequence is made asymmetric by folding in half along the transverse direction first, then folding along the longitudinal direction. This asymmetric folding pattern creates stronger structural integrity at critical points, particularly at the transverse fold portion that remains after unpacking, reducing the likelihood of tearing when the tissue is pulled out.
3Strength
If the strength of the paper tissue is increased to prevent tearing, then the tissue can be taken out without tearing, but it becomes difficult to use a paper tissue that has good usability but low strength, such as a moisturizing tissue
Solution Approach 1:
The tissue is pre-folded in half along the transverse direction before longitudinal folding, creating a structural configuration where the fold lines reinforce each other. This preliminary structural preparation allows soft, low-strength moisturizing tissues to maintain their integrity during extraction without requiring increased material strength, preserving both usability and tear resistance.

AI summary
A pocket tissue includes a stack of paper tissues 2 each of which is folded at a plurality of fold portions and a film package that contains the stack, the pocket tissue allowing the paper tissues 2 to be taken out from a dispense opening formed in an upper surface of the package. Each of the paper tissues 2 includes a first fold portion 10 located at a position that substantially bisects the paper tissue 2, a second fold portion 11 extending in a longitudinal direction of the paper tissue 2 folded at the first fold portion 10, and a third fold portion 12 extending in a transverse direction of the paper tissue 2 folded at the second fold portion 11. The stack is formed by stacking the paper tissues 2 each of which has been folded at the third fold portion 12 to be in a state in which the first fold portion 10 is exposed to the outside.
