EXTRACTION BAG Russian patent published in 2024 - IPC B65D85/808 A47J31/18 

FIELD: medical equipment.

SUBSTANCE: invention relates to a flow-through extraction bag. Provided is extraction bag 1A of a submersible type, comprising a main body of the bag having a planar shape, i.e. which is a flat bag, wherein the main body of the bag is made of a water-permeable filter cloth and is filled with an extraction material, wherein the extraction efficiency is increased due to the fact that the main body of the bag is equipped with a special gripping part, which is made of a thin plate material, as well as due to control of characteristics of water-permeable filter cloth. Extraction bag 1A comprises a bag main body 3, which is made from a water-permeable filter cloth, a thin plate element 10, which is provided on the outer surface of the bag main body 3, and an extraction material which is sealed in the bag main body 3, wherein the extraction material is subjected to extraction while being sealed in the bag main body 3. Main body 3 of the bag is a flat bag containing two opposite surfaces. Thin plate element 10 comprises gripping part 11, which protrudes or is made with possibility to protrude from upper side 3a of main body 3 of the bag or from outer surface 3x, 3y of main body 3 of the bag. Resistance to bending (determined by 41.5° cantilever method according to JIS L 1913:2010 (ISO method)) of the water-permeable filter cloth is from 0.09 to 6.0 mN·cm.

EFFECT: higher efficiency of extraction.
