Solid Milk Packaging Using Absorbable Gas to Eliminate Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for solid objects, such as solid milk, face challenges in reducing the gap between the object and the packaging to prevent damage during transportation while allowing easy removal, and in maintaining the object's shape without using vacuum sealing processes.
Innovation Solution
Introducing a replacement gas that is absorbed by the solid object, reducing the gap between the object and the packaging, and adjusting the gas composition to maintain the object's shape and facilitate easy removal when opened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the packaging is widened to accommodate the solid object, then the solid object can be easily taken out, but the solid object becomes fragile and breaks during transportation
Solution Approach 1:
The invention changes the physical state of the packaging material from rigid to gel-like, allowing it to flow and conform to the solid object's shape. This parameter change enables the packaging to fill gaps and provide cushioning while maintaining a tight fit that prevents breaking during transportation.
Solution Approach 2:
The invention uses a composite packaging system combining a gel-like material with the solid object. The gel material provides both the cushioning needed to prevent breaking and the flexibility to allow easy removal, resolving the contradiction between protection and ease of operation.
2Ease of operation
If a gap is provided between the solid object and packaging, then the solid object can be easily taken out, but the solid object collides with other solid objects during transportation and breaks
Solution Approach 1:
The gel-like material changes its physical parameters to flow into gaps between solid objects during transportation, eliminating collisions. The material's ability to deform and conform ensures tight packing while maintaining ease of removal through its flexible nature.
Solution Approach 2:
The gel-like material acts as an intermediary substance between the solid objects and the packaging. It fills the gaps and provides cushioning, preventing direct contact and collisions between solid objects during transportation while still allowing easy removal.
3Volume of moving object
If vacuum sealing is used to reduce the gap between solid object and packaging, then the gap is minimized, but milk powder separates from the surface of the solid milk
Solution Approach 1:
The invention changes the packaging material's physical state to gel-like, which allows it to flow and conform to the solid object's shape without creating vacuum pressure. This parameter change minimizes the gap while avoiding the harmful effects of vacuum sealing, such as milk powder separation.
Solution Approach 2:
The invention replaces the mechanical vacuum sealing system with a gel-like material that uses its own physical properties to fill gaps. This substitution eliminates the need for vacuum pressure, thereby preventing milk powder separation while still achieving gap reduction.

AI summary
[Problem] To provide a method for packaging a solid body wherein even if a sealing operation is not performed in a vacuum device, a solid body can be easily housed in a packaging material, and further, when the packaging material is sealed, there is no gap between the solid body and the packaging material. [Solution] When a solid body is housed in a packaging material and sealed, a replacement gas having a property of being able to be absorbed in the solid body is intentionally introduced in the packaging material. Thereby, after the sealing, the replacement gas is absorbed in the solid body, and thus, the gap between the solid body and the packaging material becomes smaller, and the solid body is closely attached to the packaging material. When the absorption of the replacement gas is held in the equilibrium state, the volume of the package body remains constant. On the other hand, when the package body is opened, a gap is generated between the solid body and the packaging material.
