Title:
TWO-POUCH MEMBRANE BAG AND METHOD OF USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/015358
Kind Code:
A1
Abstract:
A two-pouch membrane bag, comprising a membrane bag body (1), wherein a sealing strip (11) disposed at a center portion of the membrane bag body separates the membrane bag body into a membrane-liquid pouch (12) and a dry-membrane pouch (13); and a connecting member (2), one end of which is sealed in the sealing strip, and another end of which is a free end extending into the membrane-liquid pouch or the dry-membrane pouch. An inner portion of the connecting member is hollow and forms a channel (21), and at the free end of the connecting member is provided an end cover (23) that seals the channel. There is an annular indentation (22) at a periphery of the free end of the connecting member. The membrane bag adopts a two-pouch configuration and is separated into membrane-liquid and dry-membrane members, avoiding a situation in which a membrane is immersed for a long time in the membrane liquid and bacteria multiply thereon. When in use, the membrane is immersed in the liquid using the original packaging, avoiding external contamination, and an additional immersion container is not required, providing convenience.
