Ink Pack Gripping Structure for Leak-Safe Ink Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ink packs have a high risk of ink leakage during the injection process, which can contaminate the surroundings and are inefficient in handling.
Innovation Solution
The ink pack design includes a bag body with a first and second gripping portion on opposite sides of the outer periphery, allowing the ejection unit to be oriented vertically for ink injection, with gripping portions positioned to stabilize the pack and prevent ink contact with the user's fingers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ink pack is held during injection, then the user can control the injection process, but ink may leak and contact the user's fingers
Solution Approach 1:
The bag body is segmented into distinct functional regions: gripping portions positioned on side portions away from the ejection portion, and non-gripping portions in between. This segmentation allows users to grip the pack securely while the ejection portion remains accessible for injection, preventing ink contact with fingers during the process
Solution Approach 2:
The gripping portions act as intermediary structures that mediate between the user's hand and the ink pack. By providing dedicated gripping portions on the side portions, the design allows users to hold the pack without their fingers being in the direct path of ejected ink, thus preventing contamination while maintaining control
2Productivity
If the ejection portion is accessible for injection, then ink can be injected efficiently, but ink may overflow and leak during the process
Solution Approach 1:
The bag body exhibits local quality differentiation where the ejection portion is strategically positioned and accessible for efficient ink transfer, while the gripping portions are located on side portions away from the ejection area. This local differentiation allows the ejection function to be optimized for efficiency while the gripping portions provide stable holding positions that prevent leakage during operation

AI summary
An object of the present disclosure is to provide an ink pack that can suppress ink leakage during the injection of ink and has the potential to contribute to the achievement of a sustainable society such as a decarbonized/circular society. An ink pack configured to be able to inject ink into an ink tank included in a liquid discharge apparatus includes: a bag body configured to contain the ink; and an ejection portion extending from an inside to an outside of the bag body to eject the ink. The bag body includes a first gripping portion provided to one side portion of side portions forming an outer periphery, and a second gripping portion provided to a side portion different from the side portion to which the first gripping portion is provided.
