Wet Wipe Container with Frangible Tab for Easy Lid Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wet wipe dispensers often experience issues with 'multiples' and 'fallbacks' due to improper release mechanisms, and users face difficulties in easily removing the removable portion of the container, leading to product damage and improper dispensing.
Innovation Solution
A storing and dispensing container with a rigid closed-loop flange and a frangible projecting tab that assists in easy removal of the removable portion, providing a secure and reliable dispensing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly remove the removable portion of the container without assistance, then the removal process becomes difficult and time-consuming, but the container structure remains simple
Solution Approach 1:
The frangible projecting tab is pre-positioned on the container with a predetermined break location. When users pull the tab, it automatically breaks at the predetermined location to facilitate removal of the removable portion, eliminating the need for users to manually tear or cut the container material.
Solution Approach 2:
The container is divided into distinct functional components: the frangible projecting tab, the removable portion, and the main container body. The tab is separately breakable from the container structure, allowing it to serve as a dedicated removal aid that can be discarded after use.
2Reliability
If the connection between successive wipes is too strong, then the wipes remain securely in the container, but multiple wipes are pulled out simultaneously causing 'multiples' malfunction
Solution Approach 1:
The connection between successive wipes varies in strength at different locations. The leading end of each wipe has a weaker connection to allow easy separation, while other portions maintain stronger connections for secure retention. This gradient in connection strength enables reliable single-wipe dispensing.
Solution Approach 2:
The adhesive bonding or interfolding between successive wipes is intentionally designed to be partially strong and partially weak. The weak portions at the leading ends allow easy pull-away, while the overall connection strength remains sufficient to prevent multiple wipes from being dispensed simultaneously under normal conditions.
3Ease of operation
If the connection between successive wipes is too weak, then wipes can be easily separated, but the succeeding wipe falls back into the container causing 'fallback' malfunction
Solution Approach 1:
The connection strength between successive wipes is spatially differentiated: the leading end portions have weaker connections for easy separation, while intermediate and trailing portions maintain stronger connections. This local variation prevents the succeeding wipe from completely detaching and falling back into the container.
Solution Approach 2:
The adhesive bonding is applied in a controlled manner with varying intensity across different regions of the wipe stack. Sufficient adhesive is applied to prevent fallback, while strategically reduced adhesive at critical separation points enables easy wipe removal. This balanced approach achieves both reliable retention and easy dispensing.
