Wet Wipe Flip-Top Cap with Elastic Sealing Cover for Moisture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet wipe packaging technologies face issues with moisture loss and contamination due to large outlet sizes, and inconvenience in removing wipes due to small aperture sizes that require additional tools.
Innovation Solution
A wet wipe packaging system featuring a flip-top cap with an elastic sealing cover having a crisscross cut and a small-diameter outlet, accompanied by a ring-wall and clamp mechanism, and an optional hook body for easy and secure dispensing of wipes, preventing moisture loss and bacterial invasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outlet is designed with a large opening for convenience of pinching wet wipe, then it is easy to take out wet wipe, but too many wet wipes can be taken out at once and the remaining wet wipes could easily lose moisture and get contaminated
Solution Approach 1:
The sealing cover is designed as an elastic component that can dynamically change its state between closed and open. When force is applied, it opens to allow wet wipe removal; when force is removed, it automatically returns to closed state to maintain sealing. This dynamic behavior resolves the contradiction by providing ease of operation when needed while maintaining reliability when not in use.
Solution Approach 2:
The outlet size parameter is changed from a fixed large opening to a dynamically controllable opening. The elastic sealing cover allows the outlet to transition between open and closed states, effectively changing the outlet size parameter based on operational needs. This resolves the contradiction by having a large effective opening during use while maintaining a closed (small effective opening) state for sealing.
2Reliability
If the outlet is designed with a smaller size to prevent moisture loss and contamination, then sealing performance is improved, but it becomes not easy to take the wet wipes out and usually needs other tools
Solution Approach 1:
The elastic sealing cover is designed to automatically open when force is applied and automatically return to closed state when force is removed. This self-service mechanism eliminates the need for additional tools to open the outlet, while still providing a small outlet size for good sealing performance. The system serves itself by using the user's natural pinching force to open and its own elasticity to close.
3Ease of operation
If a tear-open closure is used for the outlet, then it is easy to open, but the closure is torn easily and hard to store
Solution Approach 1:
The elastic sealing cover provides a dynamic sealing solution that can be repeatedly opened and closed without tearing. Unlike a tear-open closure that is designed for single-use, the elastic cover maintains its structural integrity through repeated use, resolving the contradiction between ease of opening and resistance to accidental tearing.
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
The system ensures convenient and safe use by maintaining seal integrity, preventing moisture loss and contamination, while allowing easy removal of wipes without tools, and reducing the risk of accidental tearing.
Implementation Method 1
an elastic sealing cover (3) inside said aperture, said elastic sealing cover (3) opens when applying force on the sealing cover and closes when the force is removed

AI summary
The invention discloses a flip-top cap (A) and flip-top set with convenient outlet for taking out wet wipes. It includes the cap body (1) and the upper cover (2). The cap body has an aperture in its central part and is molded with an elastic sealing cover (3) inside, which completely cover the above-mentioned aperture; the cap body is sealed and fixed on the wet wipes outlet of the wet wipes bag. Being applied with downward force, the elastic sealing cover will open a small-diameter outlet (31) for taking out wet wipes; and when the force applying stops, the elastic sealing cover can resume back to closing state. This application solves the inconvenient wet wipes take-out problem from outlet with a small diameter, and is convenient to use.
