Toner Container Segmented Pouch for Cost-Effective Replenishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current toner replenishment methods in electrophotographic image forming apparatuses require either replacing the entire process cartridge or the developing device, which is costly and inefficient, especially when only the toner is depleted.
Innovation Solution
A toner container with a pouch for storage, a nozzle for discharge, and a film for protection, allowing for direct toner supply to the developer container without removing the entire process unit, enabling cost-effective and convenient toner replenishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire process cartridge or developing device is replaced when toner is depleted, then reliable toner supply is ensured, but operational costs and waste increase significantly
Solution Approach 1:
The toner container is divided into separate functional components: a reusable body portion and a replaceable pouch portion containing toner. This segmentation allows only the toner pouch to be replaced when depleted, while the main container structure remains in use, thereby reducing waste of the entire process cartridge or developing device while ensuring reliable toner supply.
Solution Approach 2:
The invention enables recovery and continued use of the container body after toner depletion. The pouch is discarded and replaced with a fresh toner pouch, while the container body is recovered and reused. This approach eliminates the need to discard the entire process cartridge or developing device, significantly reducing material waste while maintaining reliable toner supply.
2Quantity of substance
If the entire process cartridge is replaced, then toner replenishment is achieved, but operational efficiency and cost-effectiveness deteriorate
Solution Approach 1:
By segmenting the toner container into a permanent body and a consumable pouch, the system allows rapid replacement of only the toner pouch. This eliminates the time-consuming process of replacing entire process cartridges or developing devices, thereby improving operational efficiency while ensuring adequate toner quantity is maintained.
Solution Approach 2:
The invention employs a disposable pouch design that is inexpensive and easily replaceable. When toner is depleted, users simply replace the cheap pouch rather than the expensive process cartridge or developing device. This approach maintains adequate toner quantity while significantly improving cost-effectiveness and operational efficiency.
3Object-generated harmful factors
If a removable cap structure is used to cover the discharge port, then toner leakage is prevented, but the structure complexity and potential failure points increase
Solution Approach 1:
The invention uses a flexible pouch made of heat-sealable resin material to contain and discharge toner. The pouch itself acts as the sealing structure, eliminating the need for separate rigid caps or complex closure mechanisms. This flexible film approach prevents toner leakage while maintaining simple structure with no additional moving parts or failure points.

AI summary
A toner container that is removable from an image forming apparatus includes a storage portion including a container portion that stores toner and a front end portion including a discharge port that discharges the toner from the toner container and a nozzle including a passage that enables the toner to pass through the passage toward the discharge port. At least part of the front end portion is covered by a film that is removable.
