Stick-Shaped Material Extruding Container With Suction Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stick-shaped cosmetic material containers fail to prevent the stick-shaped material from falling off when subjected to impacts or vibrations, leading to the material breaking away from the middle plate.
Innovation Solution
A stick-shaped material extruding container with a tubular filling member and a piston-like extruding portion that moves forward and backward to securely attach and retract the material, utilizing a sucking action to maintain attachment and prevent separation during external actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stick-shaped cosmetic material is loaded directly to the sleeve with a middle plate structure, then the material can be extruded and retracted, but the material breaks away from the middle plate when impact or vibration is applied
Solution Approach 1:
The invention divides the attachment function into two separate components: the middle plate handles the extrusion and retraction motion, while the piston-like extruding portion handles the material attachment. This segmentation allows each component to specialize in its function, preventing the material from breaking away during impact or vibration while maintaining smooth operation during extrusion and retraction cycles.
2Reliability
If the extruding portion is closely attached to the filling member and material, then the material can be securely held and fed out, but the structure becomes more complex
Solution Approach 1:
The piston-like extruding portion serves multiple functions simultaneously: it acts as a seal to maintain close attachment between the extruding portion and filling member, functions as a piston to push the material during extrusion, and creates a suction effect during retraction to pull the material back. This multi-functionality reduces the need for additional separate components, thereby reducing overall structural complexity while maintaining secure material attachment.
3Duration of action of stationary object
If the stick-shaped material is closely attached within the filling member, then broken portions can be continuously used, but the material may be difficult to extrude
Solution Approach 1:
The invention employs periodic alternating actions between the extruding portion and the material: during the forward stroke, the extruding portion pushes the material forward with a pushing action; during the backward stroke, it creates a suction effect to pull the material back. This periodic pushing-pulling action maintains close attachment between the extruding portion and material, allowing broken portions to be continuously used, while the alternating motion prevents the material from becoming stuck during extrusion.
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 container effectively feeds out and retracts the stick-shaped material without issues, even with soft materials, and prevents it from falling off during impacts or vibrations, allowing continuous use and improved usability.
Implementation Method 1
a sucking action is applied on the basis of the backward movement of the extruding portion and the stick-shaped material is pulled back within the filling member

AI summary
To perform forward and backward movements of a stick-shaped material without trouble and prevent detachment of the stick-shaped material by an impact, a piston (7) in a movable body (6) arranged within a container (100) is closely attached within a filling member (1), the stick-shaped material (M) is loaded in the filling member (1) so as to be closely attached thereto, and the piston (7) is closely attached to the stick-shaped material (M), whereby the stick-shaped material (M) is pushed by a forward movement of the piston (7) to appear from an opening (1a) of the container, a sucking action generated due to decompression is applied between the piston (7) and the stick-shaped material (M) by a backward movement of the piston (7) to retract the stick-shaped material (M), and the decompression prevents falling off of the stick-shaped material (M) from the container (100).
