Cosmetic Powder Sifter with Sweeper Projection for Accumulation Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic powder containers suffer from accumulation of powder on the sifter's upper surface, leading to waste and mess, especially when stored upside-down, as they lack an effective mechanism to redirect excess powder back into the container.
Innovation Solution
A cosmetic powder accumulation management system featuring a sifter with apertures and a sweeper projection on a cover member that directs cosmetic powder from the upper surface towards the apertures for pass-through back into the container, reducing waste and mess during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a sifter is used to control powder flow, then powder distribution is improved, but powder accumulation on the sifter surface occurs causing waste and mess
Solution Approach 1:
The patent extracts the accumulated powder from the sifter surface by introducing a sweeper member that removes the accumulated powder and returns it to the container body, separating the accumulation problem from the filtration function
Solution Approach 2:
The sweeper member recovers the accumulated powder by sweeping it off the sifter surface and returning it to the container body, preventing powder loss and maintaining productivity
2Adaptability or versatility
If the container is stored upside-down, then storage flexibility is improved, but powder accumulation on the sifter surface worsens
Solution Approach 1:
The sweeper member is designed to automatically sweep accumulated powder back into the container body when the container is stored upside-down, allowing the system to self-correct without user intervention
Solution Approach 2:
The sweeper member is made rotatable relative to the container body, allowing it to dynamically adapt to different storage positions and orientations, particularly upside-down storage, to effectively sweep powder from the sifter surface
3Loss of substance
If a sweeper member is added to redirect powder, then powder accumulation is reduced, but device complexity increases
Solution Approach 1:
The sweeper member serves multiple functions: it sweeps accumulated powder back into the container body, can be rotated to different positions, and works with the existing sifter structure, maximizing utility while minimizing added complexity
Solution Approach 2:
The sweeper member is integrated with the existing container and sifter structure, combining the sweeping function with the filtration function rather than creating a completely separate system

AI summary
Cosmetic powder containers with powder accumulation management systems are provided to reduce waste and mess related to the loss of cosmetic powder. In general, examples of systems described herein generally include a sifter positioned above the cosmetic powder with apertures configured for bi-directional pass-through of cosmetic powder. In some examples, the sifter is dome-shaped with a concave upper surface. To manage accumulation of cosmetic powder on an upper surface of the sifter, a sweeper projection is provided to collect cosmetic powder on the upper surface and direct the cosmetic powder toward the apertures of the sifter for pass-through back into the container. In this regard, accumulation of cosmetic powder on the upper surface of the sifter is managed, limiting waste and mess during use of the cosmetic powder.
