Ink Refill Container Receiving Recess for Leakage Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink refill containers face issues with ink leakage due to joining failures at the junctions of the container body and inner/outer bottom plates, especially during transportation or handling, which leads to ink leakage outside the container.
Innovation Solution
The ink refill container design includes a container body with a peripheral wall, an inner bottom forming the bottom wall of the ink containing chamber, an ink-outlet forming portion for ink flow, and a cover with a receiving recess configured from the outer bottom and tubular wall that integrally couples to the outer bottom, positioned below the inner bottom, to collect and contain any leaked ink.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a double bottom is configured by joining an inner bottom plate and an outer bottom plate to the container body, then the container can maintain its structural integrity and appearance, but joining failure may occur at the junctions leading to ink leakage
Solution Approach 1:
The patent introduces a receiving recess as an intermediary structure between the inner bottom plate and the outer bottom plate. This recess accommodates potential leakage at the joining interfaces, preventing the harmful effect from propagating outward while maintaining the double-bottom structure's integrity and appearance.
2Adaptability or versatility
If the container is filled with heated liquid and then cooled at room temperature, then the liquid container can be used for temperature variation, but joining failure may occur due to thermal stress
Solution Approach 1:
The receiving recess is designed in advance to cushion and contain potential leakage that may result from thermal stress-induced joining failure. This preliminary protective structure allows the container to withstand temperature variations while preventing the consequences of thermal stress from compromising the overall system reliability.
3Reliability
If the inner bottom plate is joined to the container body, then the container can be sealed, but joining failure may occur during transportation or handling
Solution Approach 1:
The receiving recess serves as a protective intermediary that absorbs the harmful effects of drops and impact during transportation or handling. It prevents these mechanical stresses from causing joining failure at the critical interface between the inner bottom plate and the container body, while maintaining effective sealing.

AI summary
An ink refill container 31 includes a container body 61 including an inner tube portion 62 constituting an ink containing chamber 41, an inner bottom 64 joined to the inner tube portion 62, an ink-outlet forming portion 38 that is provided in the inner tube portion 62 and that includes an ink outlet 46, and a cover 75 including an outer bottom 76 covering the inner bottom 64 from below. The cover 75 includes a receiving recess 95 that is configured of the outer bottom 76 and a tubular receiving wall 93 integrally coupled to the outer bottom 76 and that receives an ink IK leaked from the ink containing chamber 41 through a junction of the container body 61 and the inner bottom 64.
