<p>A kit-form syringe which is filled with a formulation and comprises a cylindrical opened at both ends and having a communication passage near one of the opened ends, a slidable partition plug which defines a plurality of chambers in the cylinder, an elastic end partition fitted in one of the opened ends and having a passage communicating with the communication passage, and a rigid syringe needle connection adapted to be fitted in an end of the end partition. A communicating portion is formed for communication between a circumferential groove of the partition plug in the cylinder and a chemical. As for the remaining structure, provided on a tip end portion of the cylinder of a synthetic resin are a syringe needle mounting portion and a protective outer cylinder, of which a tip end is integrally provided with a tip end sealing portion for sealing the syringe needle mounting portion. The tip end sealing portion comprises a head and a twisted plate. The cylinder is unitarily formed of a resin, and has a communication groove in a front vacant chamber, which communication groove is contiguous to the syringe needle connection. A gas is charged in the front vacant chamber which is partitioned by the partition plug. Therefor, water droplets and bacteria are prevented from entering the cylinder.</p> |
