Reclosable Hygiene Bag Closure Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable hygienic article packaging fails to provide a secure, easy-to-use closure system that prevents pollution and dust from entering the package after initial opening, especially for high-speed manufacturing lines producing items like diapers and feminine pads.
Innovation Solution
A flexible packaging system with a semi-tight closing mechanism, such as a zip-lock or hooks and loops system, integrated with an easy-opening system that allows for repeated opening and closing without damaging the packaging, ensuring protection from dust and bugs, and includes a handle for transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible bag with easy-opening system is used for disposable hygienic articles, then the packaging can be easily opened to remove articles, but the remaining articles are exposed to pollution, dust, and bugs for extended periods
Solution Approach 1:
The opening system is segmented into two distinct functional parts: an easy-opening mechanism (tear notch or perforation) for initial access, and a separate reclosable mechanism (zipper, snap, or adhesive strip) for sealing. This segmentation allows the package to be easily opened while providing a dedicated sealing function to prevent pollution, resolving the contradiction between ease of opening and pollution protection.
2Adaptability or versatility
If a strap closing system is used to close the bag after opening, then the bag can be opened and closed multiple times, but the closing is not tight enough to prevent pollution and the system is complex for users
Solution Approach 1:
The harmful function of the strap (insufficient sealing) is extracted and replaced with a dedicated sealing mechanism designed specifically for tight closure. The reclosable system incorporates features like interlocking zippers, snapping surfaces, or adhesive strips that provide positive sealing action, ensuring tight closure to prevent pollution while maintaining repeated opening/closing capability.
3Adaptability or versatility
If adhesive is used on the fin to help the fin adhere to the opposing face for closing the bag, then the bag can be opened and closed as required, but the adhesive becomes polluted and hinders good operation
Solution Approach 1:
An intermediary sealing mechanism (zipper teeth, snap buttons, or adhesive strip positioned away from the opening) is introduced between the closing fin and the opposing face. This intermediary element provides the sealing function without being directly exposed to pollution from article removal, preventing the degradation of closing properties while maintaining repeated opening/closing capability.
4Adaptability or versatility
If a tab closing system is used to close the bag after filling, then the bag can be opened and closed multiple times, but the closing does not provide tight sealing to avoid pollution
Solution Approach 1:
The closing mechanism is modified to change the sealing parameter from a simple tab overlap (insufficient seal) to a positive locking mechanism. This involves introducing interlocking features such as zipper teeth that mesh, snap buttons that engage with recesses, or adhesive strips that create a bonded seal, thereby achieving tight sealing while preserving repeated opening/closing functionality.
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 packaging effectively maintains product hygiene by allowing repeated semi-tight closure, preventing pollution and dust ingress, while facilitating easy opening and handling, suitable for high-speed production lines and user convenience.
Implementation Method 1
the fin further has adhesive that helps the fin to adhere to this opposing face so the bag may remain closed

AI summary
The present invention refers to a flexible packaging, comprised by a polyethylene film, which is useful for packing disposable absorbent articles, such as disposable diapers and panties for babies and adults, feminine pads, pantiliners and the like, which may be opened and closed as many times as needed, wherein it comprises a closing system that is not altered nor loses functionality during the use and allows to open the bag to remove an article and close it again so as to protect the articles that remain inside the bag and avoid the dust, bugs or particles that may pollute same.
