Application Container Holding Portion for Flattened Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing application containers fail to effectively hold and prevent deformation or breakage of flattened application materials, particularly during loading, use, and handling.
Innovation Solution
The application container features a tubular member with a holding portion that extends along the axial direction to securely contact and hold flattened surfaces of the application material, and a feed-out mechanism that includes a screwing action to advance the material, reducing stress on the material during use.

Engineering Contradiction Analysis
1Reliability
If the application container uses a conventional tubular structure without specialized holding portions, then the device complexity is low, but the application material deforms or breaks during loading, use, and handling
Solution Approach 1:
The tubular member incorporates holding portions at specific locations where the application material is most vulnerable to deformation. These holding portions are localized structural features that provide support only where needed, rather than requiring the entire tubular structure to be complex. The holding portions are positioned to contact the flattened surface of the application material, providing targeted support that prevents deformation while maintaining overall structural simplicity.
2Reliability
If the holding portion contacts the flattened surface of the application material over a wide range, then the application material is securely held and deformation is prevented, but the device complexity increases
Solution Approach 1:
The holding portion is designed as a segmented structure with multiple contact points distributed along the axial direction. Instead of requiring a single complex support structure, the holding portion comprises multiple segments or contact regions that can be implemented through simple geometric features of the tubular member, such as ribs, protrusions, or variations in wall thickness positioned at different axial locations. This segmentation allows wide-range contact with the flattened surface while maintaining manufacturing simplicity.

AI summary
An application container for an application material includes a tubular member having a tube hole to moveably accommodate the application material in an axial direction of the tubular member, and an opening to expose the application material. A shape of the tube hole when viewed along the axial direction has a flattened shape having a major axis and a minor axis, the flattened shape extending substantially along the major axis. The tubular member includes a holding portion configured to contact the application material.
