Container for housing household tissue paper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers for household tissue paper with separate metal or resin springs for biasing the open/close lid result in a complex structure and increased parts, reducing productivity.
Innovation Solution
A container with a container body and open/close lid formed from elastic material, where the biasing member is integrally formed with the container body, allowing easy opening and reducing the number of parts, with a hardness of 20-90, and featuring embedded or connected biasing members and elastic sealing loops for improved sealing and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate metal or resin springs are used as biasing members, then the opening operation of the open/close lid becomes easy, but the structure becomes complicated and productivity decreases due to increased number of parts
Solution Approach 1:
The biasing member is integrated into the container body as a built-in elastic member, merging the biasing function with the container structure. This eliminates separate spring components and simplifies assembly, resolving the contradiction between ease of operation and productivity by maintaining the biasing effect while reducing part count and manufacturing complexity
Solution Approach 2:
The container body is designed to serve multiple functions: it provides structural containment and simultaneously houses the biasing member as an integral elastic component. This multi-functionality allows the container body to replace both the traditional container structure and the separate biasing mechanism, improving productivity while maintaining operational ease
2Ease of operation
If separate metal or resin springs are used as biasing members, then the opening operation of the open/close lid becomes easy, but the structure becomes complicated with increased number of parts
Solution Approach 1:
The biasing member is integrated into the container body as a built-in elastic member, merging the biasing function with the container structure. This eliminates separate spring components and simplifies assembly, resolving the contradiction between ease of operation and productivity by maintaining the biasing effect while reducing part count and manufacturing complexity
Solution Approach 2:
The biasing function is extracted from separate spring components and embedded directly into the container body structure. This extraction eliminates the need for additional parts while maintaining the essential biasing function, thereby reducing structural complexity without compromising ease of operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the opening operation of the open/close lid while maintaining productivity by integrating the biasing member with the container body and lid, enhancing sealing properties and stability, and allowing for easier refilling without lifting the container.
Implementation Method 1
at least a part of the container body is formed of an elastic material, and the container body has a latch that latches the open/close lid in a closing state and that releases and opens the open/close lid, and the biasing member is formed of the elastic material integrally with the part of the container body formed of the elastic material and biases the open/close lid in an opening direction

AI summary
A container 100 for housing household tissue paper and comprising: a container main body 1 having household tissue paper P housed therein and having a retrieval hole 112 from which the household tissue paper P is retrieved; and an opening/closing lid 2 rotatably attached to the container main body 1 and blocking the retrieval hole 112. The container main body 1: has at least part thereof formed using an elastic material; comprises a locking means 114 that locks the opening/closing lid 2 in a closed state and is capable of opening the opening/closing lid 2 by releasing the lock; and comprises an impelling means 3 that is integrally formed, using elastic material, with a section formed by the elastic material of the container main body 1 and impels the opening/closing lid 2 in the opening direction. As a result, a housing container for household tissue paper can be provided that has a simple opening action for the opening/closing lid and suppresses reduction in productivity.
