Bottle Nozzle Groove Capillary Ink Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink container bottles used for refilling liquid tanks in ink jet recording apparatuses often experience ink adherence to the bottle opening and surrounding areas, leading to contamination when detached, as the ink supply stops when the liquid level reaches the opening, causing dripping or trickling.
Innovation Solution
The design incorporates a nozzle with a groove or rib structure at the port opening to utilize capillary forces, drawing and retaining ink within these features, thereby preventing it from adhering to the bottle's surface during and after ink supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ink container bottle is attached to the liquid tank to supply ink, then ink can be supplied from the bottle to the tank, but ink adheres to the opening and surrounding area causing contamination
Solution Approach 1:
The harmful element (excess ink at the opening) is extracted and redirected into the groove structure, separating the ink flow path from the opening surface to prevent contamination
Solution Approach 2:
The groove acts as an intermediary structure between the ink flow and the opening surface, capturing ink that would otherwise contaminate the opening and surrounding area
2Reliability
If the liquid level rises to contact the opening to stop ink supply, then ink flow stops, but ink drips or trickles from the opening
Solution Approach 1:
The harmful dripping ink is converted into a beneficial function by redirecting it into the groove structure, where it serves as a seal or cushion rather than causing contamination
Solution Approach 2:
The groove structure serves as an intermediary that captures and manages the ink at the opening, preventing it from dripping or trickling while maintaining reliable ink supply control
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
This solution effectively reduces contamination by ensuring ink is retained within the grooves or ribs, preventing it from dripping or trickling onto the user or surrounding surfaces during and after the ink supply process.

AI summary
A bottle for a recording apparatus is used that includes a recording head for discharging liquid and a liquid tank for containing liquid supplied to the recording head. The bottle includes a bottle body for containing the liquid, and a liquid supply portion for connection to a supplied portion included in the liquid tank. The liquid supply portion includes a flow path for passing the liquid from the bottle body to the liquid tank. The liquid supply portion includes, at a distal end thereof away from the bottle body, an outer peripheral surface for connection to an inner peripheral surface of the supplied portion and a port including an opening surrounded by the outer peripheral surface for supplying the liquid to the liquid tank from the flow path. The port has a groove provided therein.
