Metal Liquid Refill Containers with Removable Pouring Parts for Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Resin liquid refill containers degrade upon repeated use, making reuse difficult due to degradation of the liquid storage portion, particularly when refilled with liquid.
Innovation Solution
A liquid refill container made of metal with a removable pouring portion and cap portion, designed for easy assembly and disassembly, allowing for reuse by washing and refilling the metal storage portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a resin liquid refill container is used for repeated refilling, then the container is easy to manufacture and dispose, but the liquid storage portion degrades and reuse becomes difficult
Solution Approach 1:
The liquid refill container is divided into three separable parts: liquid storage portion (metal), pouring portion (resin), and cap portion (resin). This segmentation allows the metal storage portion to be reused indefinitely while the resin pouring and cap portions can be replaced, resolving the contradiction between ease of manufacture and reusability.
Solution Approach 2:
The container uses composite materials: metal for the liquid storage portion (providing durability and reusability) and resin for the pouring and cap portions (providing ease of manufacture and disposal). This material combination resolves the contradiction by assigning different material properties to different functional parts.
2Ease of manufacture
If a resin liquid refill container is used for repeated refilling, then the container is easy to dispose, but the liquid storage portion degrades and reuse becomes difficult
Solution Approach 1:
By separating the container into reusable metal storage portion and disposable resin pouring/cap portions, users can dispose of only the resin parts after use while reusing the metal storage portion, maintaining ease of disposal while enabling reuse.
Solution Approach 2:
The design allows discarding of the resin pouring portion and cap portion after use, while recovering and reusing the metal liquid storage portion, thus resolving the contradiction between ease of disposal and reusability.
3Ease of manufacture
If the liquid refill container is made entirely of resin, then the container is easy to manufacture, but the liquid storage portion degrades upon repeated use
Solution Approach 1:
The liquid storage portion is made of metal instead of resin to provide superior stability and resistance to degradation upon repeated use, while the pouring and cap portions remain resin for ease of manufacture. This material selection resolves the contradiction between ease of manufacture and compositional stability.

AI summary
A liquid refill container for refilling a liquid discharge apparatus with liquid includes a liquid storage portion, a pouring portion, and a cap portion. The liquid storage portion is made of a metal and contains liquid. The pouring portion is removeably connected to the liquid storage portion and has an outlet for pouring the liquid. The cap portion is removeably attached to the pouring portion and covers the outlet.
