Folded Tissue Refill Cartridges for Carton Waste Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The excessive use and disposal of tissue box cartons contribute significantly to waste and cost, as consumers prefer smaller, more expensive cartons that contain fewer sheets, leading to increased consumption and environmental impact.
Innovation Solution
Refill cartridges of folded sheet products are packaged together, eliminating individual wrapping and using separating devices like color or rigid panels, held by a packaging material, allowing for refilling of existing dispensers and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If consumers buy smaller upright cartons, then the footprint and storage space are reduced, but the number of cartons consumed increases and cost increases
Solution Approach 1:
The tissue product is segmented into two functional components: a durable dispenser carton and replaceable refill cartridges. The refill cartridges contain the actual tissue sheets while the dispenser carton maintains its decorative and dispensing functions. This segmentation allows consumers to purchase refills in compact forms without needing to repeatedly buy new cartons, thereby reducing the total number of cartons consumed while maintaining small footprint requirements.
2Ease of manufacture
If cartons are discarded after use, then the product function is completed, but waste increases and cost increases
Solution Approach 1:
The invention applies the discarding and recovering principle by allowing consumers to discard only the depleted refill cartridges while recovering and reusing the dispenser carton. The refill cartridges are designed to be easily removed and replaced, while the decorative and functional dispenser carton remains in use. This approach eliminates waste of the carton structure itself, reducing pulp waste and environmental impact while maintaining ease of product replacement.
3Reliability
If refill cartridges are individually wrapped, then protection and separation are provided, but packaging material increases and complexity increases
Solution Approach 1:
The invention merges the protection and separation functions into a single integrated approach. Multiple refill cartridges are collectively protected and separated by shared divider boards and external packaging, rather than individually wrapping each cartridge. The divider boards provide separation between cartridges within the same package, while the external packaging protects the entire group. This merging approach reduces packaging material usage and simplifies the overall packaging structure while maintaining adequate protection.

AI summary
An environmentally friendly package containing refill folded sheets is provided. The package contains a plurality of refill cartridges stacked together. Each refill cartridge contains a stack of interfolded sheets. In one embodiment, for instance, the sheets may comprise facial tissues. Each refill cartridge is configured to refill a sheet dispenser such as a paperboard dispenser. In this manner, a consumer can continually refill a single dispenser instead of having to repurchase a dispenser each time the folded sheet product is purchased.
