Delaminatable Container With Segmented Layer Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delaminatable containers face the challenge of total delamination between the inner and outer layers during use, which complicates content unloading and affects manufacturing processes.
Innovation Solution
The delaminatable container design features a main body portion and an opening portion with a first and second tightly-attached section, forming an inwardly folded structure that prevents delamination at the opening portion and allows for easy content unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner layer and outer layer are delaminated at the main body portion, then the content can be unloaded, but the layers may totally delaminate and peel off affecting usage convenience
Solution Approach 1:
The container is divided into a main body portion and an opening portion, with the delamination function segmented to occur only at the main body portion while the opening portion maintains layer attachment to prevent total peeling
Solution Approach 2:
Different regions of the container have different layer attachment properties: the main body portion allows delamination for content unloading, while the opening portion maintains tight attachment to prevent complete layer separation
2Device complexity
If the inner layer is exposed on the body inner surface, then the structure is simplified, but the layers may easily delaminate at the opening portion
Solution Approach 1:
The layer configuration is made non-uniform: the inner layer is exposed on the body inner surface at the main body portion for simplicity, but is tightly attached at the opening portion to prevent delamination

AI summary
A delaminated container has a main body portion (150) and an opening portion (160). An accommodation space (170) of the delaminated container is formed by a body inner surface of the main body portion and an opening inner surface of the opening portion. The delaminated container includes a first layer (110) and a second layer (120). The first layer includes a first tightly-attached section (111). At the main body portion, the first layer is located closer to the body inner surface than the second layer located thereto and is exposed on the body inner surface. The second layer includes a second tightly-attached section (122). The first tightly-attached section and the second tightly-attached section are tightly attached to each other. The first tightly-attached section and the second tightly-attached section are both located at the opening portion (160) of the delaminated container.
