Powdered Raw Material Dispersion in Bottle Cap Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powdered raw materials in bottle caps often clump when released into liquid, causing an unpleasant drinking experience, and may not fill the cap properly, leading to scattering and poor fillability.
Innovation Solution
Using a powdered raw material with a degree of dispersion of 5% or higher to prevent clumping and a degree of dispersion of 40% or lower to ensure proper filling, characterized by specific particle size distribution and bulk density ranges, which enhances both fillability and dispersibility in the bottle cap and liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a powdered raw material with high dispersibility is used, then the material disperses well in liquid without clumping, but the material scatters to the outside of the bottle cap during filling
Solution Approach 1:
The patent applies parameter changes by precisely controlling the particle size distribution of the powdered raw material. Specifically, it sets D10≥2μm, D50≥5μm, D90≤40μm, and σ≤15μm to achieve optimal balance between fillability and dispersibility. This parameter optimization resolves the contradiction by finding the specific particle size range that prevents both scattering during filling and clumping in liquid.
2Productivity
If the powdered raw material is filled densely in the bottle cap, then fillability improves, but the material clumps together when released into liquid
Solution Approach 1:
The patent resolves this contradiction through parameter changes in particle size distribution. By controlling D10≥2μm, D50≥5μm, D90≤40μm, and σ≤15μm, the invention achieves a balance where the powder fills densely during manufacturing yet disperses properly in liquid without clumping. The controlled particle size range allows dense packing while maintaining individual particle separation in liquid.
3Reliability
If the powdered raw material has fine particles for good dispersibility, then it disperses well in liquid, but it scatters more during the filling process
Solution Approach 1:
The patent applies parameter changes by optimizing the particle size distribution parameters: D10≥2μm, D50≥5μm, D90≤40μm, and σ≤15μm. This controlled range ensures particles are fine enough for good dispersibility in liquid but not so fine that they scatter excessively during filling, thus resolving the contradiction between dispersibility and filling accuracy.

AI summary
Provided is a powdered raw material, which is housed in a housing portion (12) of a type of a bottle cap 1 which has the housing portion (12) that houses the powdered raw material, and of which the housing portion (12) is opened by an uncapping operation, and then causes the raw material to be released into the bottle. Using a multi-functional powder property measuring instrument multi-tester, the powdered raw material is dropped onto a watch glass from a powder falling point, a dropped mass and a mass on the watch glass are measured, and a degree of dispersion which is obtained from the following formula (1) is equal to or more than 5% and equal to or lower than 40%. degree of dispersion%=dropped mass-mass on the watch glass/the dropped mass×100
