<p>PURPOSE: To provide a plastic bag for infusion which prohibits the intrusion of air and decreases the amt. of the residual liquid. CONSTITUTION: This plastic bag 1 for infusion consisting of an opening 3, cylindrical part 2 and a bottom part consists of a plastic bag formed to the diameter and thickness of the cylindrical part 4 near the aperture 3 of the bag to the diameter smaller than the diameter and thickness of the cylindrical part 2 of the bag body. As a result, the discharge of a content liquid is possible without a possibility of the intrusion of the air in an infusion. The infusion is successively discharged from the cylindrical part of the first bag body particularly in the case the infusion of a large amt. is executed by connecting these plastic bags and using such bags. The injection of the infusion without the resudual amt. of the liquid is thus possible.</p> |
