Two-Row Gusseted Toilet Paper Roll Packaging with Perforated Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet paper roll packages face issues with difficulty in unsealing and storage, as individually wrapped rolls are exposed to moisture and take up too much space, and double-wrapping complicates access.
Innovation Solution
A gusseted package design with individually wrapped toilet paper rolls arranged in two rows, featuring a thicker exterior film and a user-friendly unsealing mechanism with perforations for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If toilet paper rolls are individually wrapped and then collectively wrapped for commercialization, then protection against moisture and ease of storage are improved, but the complexity of unsealing and taking out individual rolls increases
Solution Approach 1:
The package is divided into multiple compartments, each containing a single toilet paper roll. The exterior film is segmented into separate sealed compartments that can be individually accessed. This segmentation allows the package to protect multiple rolls from moisture while enabling easy access to individual rolls by opening only one compartment at a time.
Solution Approach 2:
The exterior film compartments are pre-sealed during manufacturing to protect the toilet paper rolls from moisture. The perforations are pre-formed to guide the unsealing process. This preliminary sealing action ensures protection is already in place before use, while the pre-formed perforations make subsequent unsealing simple.
2Volume of stationary object
If multiple toilet paper rolls are collectively wrapped without individual wrapping, then storage space is reduced, but protection against moisture and ease of individual access deteriorate
Solution Approach 1:
The package uses multiple small sealed compartments instead of one large open space. Each compartment contains a single roll and is sealed to protect from moisture. This segmentation maintains compact storage volume while providing individual protection for each roll against moisture exposure.
Solution Approach 2:
Individual toilet paper rolls are nested within sealed compartments of the exterior film. Each roll is contained within its own protective envelope formed by the exterior film, creating a nested structure that saves space while maintaining individual protection.
3Object-affected harmful factors
If toilet paper rolls are double-wrapped for protection and storage, then protection against moisture is improved, but the time required to unseal and take out rolls increases
Solution Approach 1:
The exterior film compartments are pre-sealed with perforations during manufacturing to indicate where opening should occur. This preliminary preparation of the sealing structure allows users to quickly tear open the packaging without needing to search for or create an opening, significantly reducing unsealing time while maintaining protection.
Solution Approach 2:
The perforations allow the exterior film to be easily torn open and removed, extracting the protected toilet paper roll from its protective envelope quickly. This extraction mechanism separates the protective function from the access function, allowing rapid retrieval.
4Ease of operation
If individually wrapped toilet paper rolls are collectively packaged, then ease of individual access is improved, but the package size and storage requirements increase
Solution Approach 1:
The package is divided into multiple small compartments arranged in a compact configuration. Each compartment is accessible individually, allowing easy access to any roll without disturbing others. The segmented structure is arranged to minimize overall package volume while maintaining individual access capability.
Solution Approach 2:
Multiple individual roll compartments are merged into a single collective package structure. The exterior film is formed into a multi-chamber configuration that combines several individual storage spaces into one unified package, reducing the number of separate packages needed while maintaining individual access.

AI summary
To provide a toilet paper roll package that can be easily unsealed and that makes it possible to take out toilet paper rolls. The toilet paper rolls are arranged in two rows with the peripheral surfaces abutting between the upper sealing portion and the lower sealing portion in gusset packaging, the upper sealing portion and the lower sealing portion are located at a position facing the peripheral surfaces of the toilet paper rolls, in the surface of the exterior film facing the end surface of the toilet paper roll, an unsealing portion formed by a perforation is formed, this unsealing portion includes an unsealing start portion with U-shaped or substantially V-shaped perforations arranged such that the upper sealing portion side is the top side, and a wide belt-shaped outlet forming portion formed by a pair of perforations that are continuous with both ends of the unsealing start portion and that extend toward the lower sealing portion, the unsealing start portion is closer to the upper sealing portion than the position adjacent to a pair of toilet paper rolls located closest to the upper sealing portion, and has an unsealing start auxiliary perforation extending from the U-shaped or substantially V-shaped top to the upper sealing side, and each perforation forming the outlet forming portion is located on the toilet paper roll group of each row arranged in two rows, and has a width of 0.5 to 1.2 times the toilet paper roll diameter.
