AI Technical Summary
Technical Problem
Existing atmosphere control devices face challenges in efficiently filling a high amount of particulate active substances within a reduced volume, especially at high production rates, due to the preference for small particle sizes that compromise filling efficiency.
Method used
A gas-permeable envelope chamber filled with a multimodal particulate mixture of relatively large and small particles, characterized by a specific gap-graded particle size distribution, allowing for efficient filling and increased weight within small volumes.
Benefits of technology
The solution enables higher filling weights of active substances in small chambers, maintaining efficiency even at high production rates, with improved homogeneity and stability of the particle mixture.

Abstract
This atmosphere control device (1), intended for regulating an atmosphere in a packaging or a medical device containing sensitive or odorous products, comprises a gas-permeable envelope (10) defining a chamber (13), the chamber (13) having in its inner volume a particulate mixture (6) comprising at least a first active substance (61) in particulate form having relatively large particles and a second active substance (62) in particulate form having relatively small particles. The particle size distribution of the particulate mixture (6) is such that the graph of the cumulative particle size distribution by mass Q3(x) of the particulate mixture includes, between the 3% percentile d3 and the 97% percentile d97, a portion in which the cumulative mass is increased by less than 10%, preferably less than 5%, when the particle size x is doubled.
