Metered Powder Dispensing Container with Valve Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sifter jars for cosmetic powders are prone to uncontrollable dispersion, leading to waste and premature wear due to their reliance on sifting mechanisms, which also risk clogging and require careful cleaning to avoid further dispersal of the powder.
Innovation Solution
A powder dispensing jar equipped with a valve mechanism that separates the storage and dispensing chambers, allowing controlled dispensation through a metering valve activated by the cover member, eliminating the need for a sifter and minimizing powder dispersal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sifter mechanism is used to dispense powder, then the powder can be transferred from storage, but the powder becomes difficult to control and disperses uncontrollably
Solution Approach 1:
The patent removes the sifter mechanism entirely and replaces it with a valve-based metering system. The harmful sifting action that causes uncontrollable dispersal is extracted from the design, leaving only the necessary powder transfer function through a controlled valve mechanism that prevents widespread powder dispersion.
Solution Approach 2:
The patent introduces a valve mechanism as an intermediary between the powder storage chamber and the dispensing area. This valve acts as a mediator that controls powder flow, allowing only measured amounts to pass through while preventing the uncontrolled dispersal that occurs with direct sifter exposure.
2Productivity
If a sifter mechanism is used, then powder can be dispensed, but the sifter becomes clogged and requires cleaning
Solution Approach 1:
The patent eliminates the sifter component that is prone to clogging and requires cleaning. By replacing it with a valve mechanism, the design removes the source of maintenance problems while maintaining powder dispensing functionality.
Solution Approach 2:
The patent employs a disposable or easily replaceable valve mechanism that can be quickly cleaned or replaced if clogged, rather than requiring careful disassembly and cleaning of the sifter mechanism. This approach reduces maintenance complexity and time requirements.
3Ease of operation
If the jar is opened to access powder, then the user can dispense powder, but the powder billows and disperses in an uncontrollable fashion
Solution Approach 1:
The patent pre-loads a measured amount of powder onto the valve mechanism before the user opens the jar. This preliminary action ensures that only the specific quantity needed for dispensing is exposed, preventing powder waste from billowing and dispersing when the jar is opened.
Solution Approach 2:
The valve mechanism serves as an intermediary that holds a controlled amount of powder ready for dispensing. When the user opens the jar, the powder is already metered and prepared, allowing access to the exact amount needed without causing unwanted dispersal of excess powder.

AI summary
A powder dispensing container is provided, the container divided into a powder storage chamber and a powder dispensing chamber with an opening between the two controlled by a valve mechanism. A cap or closure member is disposed over an upper open end of a powder dispensing chamber and when opened, causes a closure of the valve mechanism. When the cover is returned to its closed position, the valve will automatically open allowing for new charge of powder form the storage chamber to enter into the dispensing chamber. The closure member is provided with an actuator that extends through the powder dispensing chamber and engages and causes operation of the valve mechanism.
