Liquid Pack Spout Design Reduces Ink Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ink packs experience a high ratio of loss ink when used with winding mechanisms, as the ink remaining in the spout is not efficiently reduced.
Innovation Solution
The liquid pack design incorporates a pouch with a liquid storing chamber and a liquid-non-storing chamber, where the liquid-non-storing chamber is positioned to be separated from the spout by the liquid storing chamber and the sealing part, allowing for reduced ink volume without altering the outer shape of the pouch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the spout is connected directly to the liquid storing chamber, then the liquid can flow freely through the channel, but the remaining liquid in the spout increases during squeezing
Solution Approach 1:
The pouch is divided into two separate chambers: a liquid storing chamber that communicates with the spout channel, and a liquid-non-storing chamber that is separated from the spout by the sealing part. This segmentation allows the liquid to be stored in one chamber while the spout is positioned to minimize residual liquid in the other chamber, thereby reducing waste during squeezing operations.
2Loss of substance
If the pouch volume is reduced to minimize remaining ink, then the outer shape of the pouch must be altered, but changing the outer shape affects compatibility with existing packaging systems
Solution Approach 1:
Instead of reducing the overall pouch volume or altering the external dimensions, the invention utilizes internal spatial arrangement by creating separate chambers within the existing pouch geometry. The liquid-non-storing chamber is positioned and separated in a way that optimizes liquid discharge without changing the pouch's outer shape, thus maintaining compatibility with existing packaging systems while minimizing residual liquid.

AI summary
There is provided a liquid pack including: a pouch configured to store a liquid therein; and a spout configured to be connectable to a part at one end in a first direction of the pouch, and having a channel in which the liquid passes. The pouch has: a liquid storing chamber configured to store the liquid therein and communicating with the channel of the spout, a sealing part configured to seal surrounding of the liquid storing chamber, and a liquid-non-storing chamber which is positioned to be separated with respect to the spout by the liquid storing chamber and the sealing part, and in which the liquid is not stored.
