Wet Tissue Package Lid Structure for Stable Container Opening Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container arrangements for wet tissues often misalign their openings when the package is low, leading to instability in dispensation, and may allow dust or dirt entry due to modifications in the container design.
Innovation Solution
A container arrangement featuring a package with a lid that has an opening-closing portion and a proximal portion bonded with different adhesives, allowing the lid to be peeled off and turned over, maintaining the positional relationship between the package and container openings, preventing misalignment and dust entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the package is housed within the container without securing mechanism, then the package can be easily inserted and removed, but the package moves within the container when the package is low in wet tissues, causing misalignment between openings
Solution Approach 1:
The lid of the package is preliminarily prepared with a peeling structure that allows it to be separated from the package body. This preliminary action enables the lid to be peeled off and turned over to engage with the container, securing the package in position before dispensation begins, thus preventing misalignment while maintaining ease of operation.
2Ease of manufacture
If a cut is formed in the bottom wall of the container to allow package insertion, then the package can be easily inserted, but dust or dirt may enter the container through the cut and wet tissues may dry
Solution Approach 1:
The lid is preliminarily designed with a peeling structure that enables it to be separated from the package body and turned over to engage with the container. This preliminary preparation allows the container to remain sealed during insertion while still enabling easy package access through the peeling mechanism, thus preventing dust and dirt entry without compromising ease of manufacture.
3Strength
If the lid is firmly bonded to the package body, then the package structure is strong, but the lid cannot be peeled off and turned over to secure the package in the container
Solution Approach 1:
The lid is designed with local quality differentiation: the bonding between the lid and package body is made peelable at specific locations, while maintaining overall structural strength. This local quality change allows the lid to be peeled off and turned over to engage with the container, providing adaptability without compromising the overall package strength.
Solution Approach 2:
The lid bonding is designed to be dynamic rather than static - it transitions from a bonded state to a peelable state. This dynamic characteristic allows the lid to remain attached during normal handling but can be separated when needed for repositioning, thus maintaining both strength and adaptability.
4Strength
If the opening-closing portion is bonded with strong adhesive, then the bond is strong, but the opening-closing portion cannot be repeatedly peeled off
Solution Approach 1:
The adhesive parameters are specifically selected to provide a balance between bond strength and peelability. The adhesive is chosen to have sufficient initial bonding strength to hold the lid in place, but also allows for repeated peeling without complete bond failure. This parameter optimization enables both strong bonding and repeated peeling operations.
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
Ensures stable dispensation of wet tissues by maintaining the alignment of openings and preventing dust or dirt from entering the container, even when the package is low, allowing for easy one-handed operation and reuse.
Implementation Method 1
The lid of the package is bonded to a top of the body of the package by an adhesive applied to one side of the lid

AI summary
It is an object of the invention to provide a technique for taking out an article from a package housed within a container. Wet tissues 130 are stored in a package 100, and the package 100 is housed within a container 200. The package 100 has an opening-closing portion 120B formed by a laminated portion of a first sheet 121 and a second sheet 122, and a proximal portion 120A formed by a portion of the second sheet 122 which protrudes from the first sheet 121. One side of the first sheet 121 is removably bonded to the top of the body 110 by a first adhesive 123. One side of the second sheet 122 is bonded to the other side of the first sheet 121 and also to the top of the body 110 by a second adhesive 124. The package 100 is housed within the container 200 in the state in which the opening-closing portion 120B of the lid 120 is peeled off the top of the body 110, turned over and bonded to the back of the body 110 by the first adhesive 123.
