Delaminatable Container Thermal Insulation via Shrinking Inner Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delaminatable containers fail to effectively prevent the deterioration of contents, such as cosmetics, under high-temperature environments due to inadequate heat insulation.
Innovation Solution
A delaminatable container design featuring a resin-molded tubular outer case with a container body comprising an outer shell and an inner bag that shrinks as contents decrease, creating a gap for improved heat insulation, and a flanged portion supported by the outer case to enhance thermal protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the container body is placed directly in the outer case without sufficient gap, then the structural stability is improved, but the heat insulation performance deteriorates
Solution Approach 1:
The patent introduces an outer case as an intermediary element between the container body and the external environment. This outer case creates a thermal barrier that mediates heat transfer, protecting the container body and contents from high-temperature environments while maintaining structural stability through the flanged portion support system.
Solution Approach 2:
The patent implements a nested structure where the container body is placed inside the outer case, creating concentric layers. This nesting arrangement allows the formation of insulating gaps between layers while maintaining overall structural integrity through the flanged portion engagement with the outer case.
2Object-affected harmful factors
If a large gap is formed between inner bag and outer shell for heat insulation, then the heat insulation performance is improved, but the structural stability deteriorates
Solution Approach 1:
The patent applies local quality by creating heat insulation gaps in specific locations (between inner bag and outer shell) while maintaining structural stability through localized support elements. The flanged portion and supporting portion provide localized structural reinforcement that compensates for the insulating gaps, allowing heat insulation performance to improve without compromising overall structural stability.
3Stability of the object's composition
If the flanged portion is supported by the outer case with bottom surface contact, then the structural stability is improved, but the heat insulation performance deteriorates
Solution Approach 1:
The flanged portion support structure implements local quality by providing structural stability at specific contact points (bottom surface of flanged portion with supporting portion of outer case) while maintaining heat insulation gaps in other areas. This localized support approach ensures structural stability without creating continuous thermal conduction paths that would compromise overall heat insulation performance.

Function Achieved in This Case
The design effectively suppresses content deterioration by improving heat insulation through the gap formation between the inner bag and outer shell, maintaining the quality of contents under high-temperature conditions.
Implementation Method 1
Since the heat insulating property is improved by this gap, deterioration of the contents under high-temperature environment can be suppressed
