Cellulosic Closure Mechanism for Recyclable Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rigid board packaging containers with embedded magnets are not recyclable, requiring disassembly to remove magnets before recycling, which is time-consuming and wasteful.
Innovation Solution
A container design using cellulosic materials with integrated, biodegradable closure apparatuses that allow for easy opening and closing without magnets, facilitating recyclability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If embedded magnets are used to hold the lid in place, then the container can be kept closed, but the container cannot be easily recycled
Solution Approach 1:
The patent removes magnets entirely from the container system. Instead of using embedded magnets to hold the lid closed, the invention uses a tab-and-slit mechanical interlocking mechanism where the lid has a slit and the base has a tab that fits into it, eliminating the need for magnetic components and enabling direct recycling of the entire container
Solution Approach 2:
The container is designed with separable components including a removable lid and base that can be easily separated. The lid includes a tab structure with slits that allow it to be inserted into or removed from the base, creating a segmented design that facilitates disassembly and recycling without requiring specialized equipment
2Reliability
If embedded magnets are used to keep the box closed, then the closure is secure, but disassembly is required for recycling which wastes time and material
Solution Approach 1:
The container features pre-formed tabs and slits during manufacturing that create a ready-to-use mechanical closure system. The tab is pre-positioned on the base and the slit is pre-cut in the lid, allowing the container to be assembled and closed simply by inserting the lid into the base without requiring any additional assembly steps or tools
Solution Approach 2:
By completely removing magnets from the design, the patent eliminates the need for complex disassembly procedures. The mechanical tab-and-slit system can be easily separated by hand, allowing the lid to be pulled out from the tab without requiring any special tools or time-consuming processes
3Ease of operation
If embedded magnets are used in the container, then the lid can be held in place, but the container structure becomes more complex
Solution Approach 1:
The patent integrates the closure function directly into the structural elements of the container. The tab is formed as an integral part of the base structure, and the slit is incorporated into the lid design, merging the closure mechanism with the container's basic structure rather than adding separate magnetic components
Solution Approach 2:
The invention eliminates magnets and any associated complex assembly requirements. The closure mechanism is reduced to simple geometric features (tab and slit) that can be formed during standard paperboard manufacturing processes, dramatically simplifying the overall container structure and manufacturing

AI summary
A container (100) includes a plurality of wall panels (110) that define an internal volume (138). The plurality of wall panels (110) include a front wall panel (112) that defines an opening (120). The container (100) further includes a lid (116) connected to one of the plurality of wall panels (110). The lid (116) includes a cover panel (118) and a front flap panel (114). The front flap panel (114) is defined by a flap fold line (142) and has a first surface (114a) and an opposing second surface (114b). The container (100) further includes a closure apparatus (130) affixed to the second surface (114b) of the front flap panel (114). The closure apparatus (130) is sized and shaped to be closely received with the opening(120) in the front wall panel (112). The closure apparatus (120) includes a cellulosic material.
