Multi-Stage Cosmetic Pulverization for Airless Pump Blockages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic containers with airless pumps face issues with blockages in the discharge pathway due to granulated cosmetics being trapped, leading to reduced discharge efficiency and elevated internal pressures when the granulated cosmetics are not finely pulverized to match the size of the mesh holes.
Innovation Solution
A multi-staged pulverizing apparatus within the cosmetic container, comprising a pulverizing member, a first pulverizing mesh, and a second, finely pulverizing mesh, that progressively reduces the size of granulated cosmetics as they are discharged, preventing blockages and ensuring smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If granulated cosmetics are discharged through a mesh body with fine holes, then the cosmetic discharge efficiency is improved, but the granulated cosmetics may be trapped and cause blockages if they are not finely pulverized
Solution Approach 1:
The mesh body is segmented into multiple stages with progressively smaller hole sizes. The first mesh body has larger holes to allow initial passage of granulated cosmetics, while the second mesh body has finer holes for final filtration. This segmentation prevents blockages by allowing granules to pass through the first stage before being refined by the second stage.
Solution Approach 2:
The pulverizing member performs preliminary pulverization of granulated cosmetics before they reach the mesh bodies. This preliminary action reduces the size of granules in advance, ensuring they can pass through the mesh holes without causing blockages, thereby maintaining reliable discharge operation.
2Reliability
If the granulated cosmetics are not pulverized to match the mesh hole size, then the discharge pathway may be blocked, but adding pulverization structures increases device complexity
Solution Approach 1:
The pulverizing member serves multiple functions: it pulverizes granulated cosmetics to match mesh hole sizes, guides the cosmetic flow, and works in conjunction with the pump mechanism. This multi-functionality reduces the need for separate dedicated pulverization devices, thereby limiting the increase in overall device complexity while achieving reliable blockage prevention.
Solution Approach 2:
The pulverizing member is nested within the pump chamber, and the mesh bodies are nested within the discharge pathway. This nested arrangement integrates the pulverization function into the existing pump structure without requiring separate external components, thus minimizing the increase in device complexity while ensuring reliable operation.
3Device complexity
If a single mesh body is used for pulverization, then the device complexity is reduced, but the pulverization effect is insufficient to prevent blockages
Solution Approach 1:
The mesh body is divided into two stages with different hole sizes. The first mesh body has larger holes that allow initial passage of granulated cosmetics, while the second mesh body has finer holes for final filtration. This two-stage segmentation achieves effective pulverization and blockage prevention without requiring overly complex single-stage structures.
Solution Approach 2:
Different regions of the discharge pathway are assigned different mesh hole sizes according to local requirements. The first mesh body region uses larger holes suitable for initial granule passage, while the second mesh body region uses finer holes for final refinement. This local quality differentiation optimizes pulverization effectiveness at each stage while maintaining overall device simplicity.

Function Achieved in This Case
The multi-staged pulverization process enhances the discharge efficiency of granulated cosmetics, preventing blockages and maintaining normal internal pressures, resulting in uniform application and improved cosmetic performance.
Implementation Method 1
a pump connected to the top of the container, such that the contents in the container are discharged to the outside in a fixed amount by the pumping power afforded by causing a pushing action
Implementation Method 2
because it is in the form of solid granules, while colliding with a plurality of members in the discharge path, it is caused to have a greatly reduced size
Implementation Method 3
a pulverizing member having a plurality of large holes through which a first pulverization can be caused while the granulated cosmetic passes therethrough, a pulverizing mesh for subjecting the granulated cosmetics which have passed through said pulverizing member to a second pulverization

AI summary
A cosmetic container having a storage container for housing a liquid- or gel-form basic cosmetic and a granulated cosmetic having a different function from the basic cosmetic, an airless pump on top of the storage container for discharging the mixed cosmetics from the storage container, and pulverization apparatus including a pulverizing member, a first pulverizing mesh and a second, finely pulverizing mesh positioned in a plurality of stages in a discharge pathway within the airless pump to cause the granulated cosmetic in the mixed cosmetics to be finely pulverized in a plurality of stages, with multistage smashing and fine pulverization of the granulated cosmetic in the pump such that discharge of the cosmetic is thereby performed smoothly when the cosmetic is used.
