MOUTH PLUG FOR INFUSION SOLUTION BAG

摘要

PROBLEM TO BE SOLVED: To provide a rubber plug which increases the tightening force to an impalement needle and the closing force of a hole formed by the impalement of the needle. SOLUTION: The mouth plug body to be mounted in the main body aperture of an infusion solution bag made of a synthetic resin is in a tight contact state by receiving the compressive stress from a rubber plug contour supporting body made of a synthetic resin at the entire flank in the cylindrical part of the rubber plug. At least one of the top surface and base surface of the rubber plug is contracted in diameter by 1 to 10% and the top surface or the base surface is bulged.
