Gusseted Tissue Package Outlet Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In film-packaged tissue assembly packages, the outlet forming portion can be rubbed against the gusset packaging film, causing it to turn up, and excessive compression can lead to reduced fullness of the tissue paper over time.
Innovation Solution
The film-packaged tissue assembly package features a non-slit-shaped annular outlet forming portion at the end of each tissue, arranged in a traverse direction and gusset-packaged, with specific slit cuts and perforations to prevent rubbing against the gusset packaging film and maintain tissue fullness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outlet forming portion is arranged in a thin and long annular shape to widen the opening, then sheet drawability is improved, but the outlet forming portion is rubbed against the gusset packaging film and turned up
Solution Approach 1:
The outlet forming portion changes its shape parameter from a thin annular shape to a thick annular shape with increased radial thickness. This parameter change allows the outlet to maintain adequate opening area for sheet drawability while the increased thickness prevents rubbing against the gusset packaging film, thus resolving the contradiction between ease of operation and reliability
Solution Approach 2:
The gusset packaging film is designed with a groove that receives the outlet forming portion beforehand. This prior cushioning structure prevents the outlet forming portion from being rubbed against the film during compression and transportation, maintaining its stability while preserving the annular shape needed for sheet drawability
2Stability of the object's composition
If film-packaged tissues are arranged side by side and compressed for gusset-packaging, then shape retainability is improved, but the outlet forming portion is rubbed against the packaging film
Solution Approach 1:
The groove structure in the gusset packaging film provides beforehand cushioning for the outlet forming portion. This prevents harmful rubbing during the compression process needed for shape retainability, thus resolving the contradiction between stability of composition and reliability
Solution Approach 2:
The groove acts as an intermediary structure between the outlet forming portion and the gusset packaging film. It mediates the compression force while protecting the outlet forming portion from direct contact and rubbing, allowing shape retainability without compromising outlet integrity
3Ease of operation
If the slit length is increased to improve sheet drawability, then outlet opening is widened, but the sheet falls to the inside when the number of sheets remaining decreases
Solution Approach 1:
The outlet forming portion transitions from a linear slit to an annular shape with increased radial thickness. This parameter change provides a wider opening area for improved sheet drawability while the annular configuration with substantial thickness prevents sheets from falling inside, maintaining sheet position stability throughout product usage

AI summary
Provided is a film-packaged tissue assembly package in which an outlet forming portion is not unintentionally broken. The problem is solved by a film-packaged tissue assembly package in which a plurality of substantially hexahedron-shaped film-packaged tissues having an upper surface having an outlet forming portion are arranged and packaged in a gusset packaging bag having a grip portion on the top surface side, wherein a plurality of film-packaged tissues are arranged in a substantially rectangular parallelepiped shape in such a manner that the end surfaces face the top surface side where the grip portion is provided, and a bottom surface side facing the top surface side, and the film-packaged tissue is packaged in such a manner that the outlet forming portion has a shape in which an easily tearable line having cut portions and non-cut portions arranged alternately protrude toward the outside, the interval between non-cut portions at one end portion is smaller than the interval between non-cut portions at the other end portion, and the side where the end portion with a smaller interval between non-cut portions is located on the top surface side.
