Wipe Dispenser Closure with Stop-Limited Cap for Self-Closing Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices for wipe dispensers often fail to ensure proper closure after wipe removal, leading to contamination and drying out of wipes due to complex designs that require frequent re-use and cleaning.
Innovation Solution
A mechanically simple closure device with a main body and cap, featuring a hinge section and stop bodies that limit the cap's opening angle, allowing for easy wipe removal while promoting self-closure and preventing complete opening, thus maintaining hygiene and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex multi-part closure system with spring elements is used to achieve automatic closure, then the closure reliability is improved, but the device complexity increases and cleaning becomes difficult
Solution Approach 1:
The closure device is divided into two separate functional components: a cap that opens and closes the opening section, and a flange that provides attachment to the wipe dispenser. This segmentation simplifies each component's function and makes the overall system easier to manufacture and clean while maintaining reliable closure through their coordinated interaction.
2Ease of operation
If the cap can open completely for easy wipe removal, then the ease of operation is improved, but the risk of contamination and drying out increases
Solution Approach 1:
The cap is designed with dynamic movement capability through the hinge section, allowing it to swing open for wipe removal and automatically spring back to a closed position. This dynamic design enables the cap to transition between open and closed states, facilitating easy wipe removal while ensuring automatic closure to prevent contamination and drying out of remaining wipes.
3Ease of manufacture
If a simple mechanical closure device is used to reduce complexity, then the ease of manufacture is improved, but the closure reliability may deteriorate
Solution Approach 1:
The closure device is designed to be self-closing through the spring back mechanism provided by the hinge section. When the cap is released after wipe removal, it automatically returns to the closed position without requiring user intervention. This self-service feature ensures reliable closure while maintaining mechanical simplicity and ease of manufacture.
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 closure device effectively prevents contamination and drying out by ensuring the cap springs back into a closed position after wipe removal, requiring minimal user effort to close, and can be easily integrated with existing wipe dispensers without modifications.
Implementation Method 1
A hinge section, in which the cap is held movably on the main body, is arranged between the main body and the cap
Implementation Method 2
at least one stop body extends radially outwards on the hinge section from the cap and is designed to enter into mechanical stop contact with the wipe dispenser when the cap is opened and thereby to limit a possible opening angle of the cap
Implementation Method 3
The closure device effectively prevents contamination and drying out by ensuring the cap springs back into a closed position after wipe removal

AI summary
A closure device (2) for a wipe dispenser has a main body (4) and a cap (6) arranged movably thereon, wherein the main body (4) has a fastening section (10) for fastening the main body (4) on the wipe dispenser, an opening section (24), which can be completely covered by the cap (6), and a bottom (30) having a cutout (32) for passing through wipes from the wipe dispenser. The fastening section (10) has at least one first engagement means (14) for connection to the wipe dispenser. A hinge section (8), in which the cap (6) is held movably on the main body (4), is arranged between the main body (4) and the cap (6). At least one stop body (50) extends radially outwards on the hinge section (8) from the cap (6) or from the main body (4) and is designed to enter into mechanical stop contact with the wipe dispenser or with the main body (4) when the cap (6) is opened and thereby to limit a possible opening angle (α) of the cap (6).
