Tissue Wipe Dispensing Unit With Airtight Lid Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tissue wipe containers face issues with easy removal of tissue wipes due to the dispensing hole shaping member falling and inadequate airtightness, leading to drying of tissue wipes.
Innovation Solution
A tissue wipe container design featuring a dispensing unit with an engaging part and a lid that provides airtight closure, where the dispensing unit is securely engaged with the case and the lid contacts the dispensing unit to prevent disengagement and maintain airtightness, allowing easy pull-out of tissue wipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dispensing hole shaping member is detachably attached to the dispensing opening from below, then it provides resistance to tissue wipes for cutting along perforation, but it readily falls when pressed from above causing difficult removal of tissue wipes
Solution Approach 1:
Instead of attaching the dispensing hole shaping member from below (conventional approach), the invention attaches it from above by inserting the elongated portion through the opening from the upper side. This inversion of the attachment direction prevents the shaping member from falling when pressed, while still allowing tissue wipes to be pulled out through the opening for easy removal.
2Reliability
If there is a space between the dispensing hole shaping member and the lid when the lid is closed, then the lid can close properly, but the tissue wipes may end up drying
Solution Approach 1:
The invention introduces a curved surface on the upper face of the upper annular portion of the dispensing hole shaping member. This curved surface enables proper contact with the lid when closed, eliminating gaps and ensuring airtightness to prevent tissue wipes from drying, while maintaining a relatively simple overall structure.
3Reliability
If the dispensing hole shaping member is securely engaged with the case, then it prevents falling and disengagement, but it may complicate the engaging part structure
Solution Approach 1:
The engaging part is divided into distinct functional segments: an elongated portion for insertion through the opening, an upper annular portion with a curved surface for contact with the lid, and a lower annular portion for engagement with the case. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure clear and manageable.

AI summary
A tissue wipe container includes a case which stores therein a roll of tissue wipes with perforations and which is provided with a dispensing unit having an opening through which the tissue wipes pass in a vertical direction to be pulled out to an outside upon being separated along the perforations, and a lid attached to the case in such a manner as to open and close the opening of the dispensing unit, wherein the dispensing unit is provided with an engaging part for causing the dispensing unit to be engaged with the case, the engaging part has a constricted portion formed in a side surface of the dispensing unit at a center in the vertical direction along a circumferential direction, an edge of a mount opening of the case being inserted into the constricted portion to cause the engaging part to be engaged with the mount opening, and the lid is in contact with the dispensing unit to provide airtight closure when the lid closes the opening of the dispensing unit.
