PURPOSE:To provide a simple method for sealing the mouth of a synthetic resin vessel used for transfusion and to lessen the resistance generated on thrusting a needle into the vessel, by inserting a rubber cap in the mouth of the vessel and then heating and pressing the upper part of the mouth integrally to be bent down and fixed on the rubber cap. CONSTITUTION:A rubber cap 5 is inserted in a mouth 2 of a synthetic resin vessel 1 used for transfusion; and the upper part of the mouth 2 is covered and pressed with a metal cap 6 and is then heated with a welding heater 7 mounted on the metal cap 6, thereby being bent down and fixed integrally on the rubber cap 5. The sealing method as mentioned above does not require many component parts and is thus simple and not costly. When a needle is thrusted into the vessel 1, it passes through only the rubber cap 5; and the resistance against the insertion of the needle is hence lowered. |
