<p>PROBLEM TO BE SOLVED: To solve a problem in a process with superior holding force as against needle removal and re-sealing property by providing a stopper body which is formed by means of laminating thin layers consisting of one of a thermoplastic elastomer, a gellatized resin, a low-density polyethylene and a composition obtained by kneading them with rubber. SOLUTION: A medical cap 1 is provided with the stopper body which is formed by one of a thermalplastic elastomer, a gellatized resin, a low-density polyethylene and a composition obtained by keading them with rubber. Then, the thermoplastic elastomer is inferior to the gellatized resin, the low-density polyethylene or the composition obtained by kneading them with rubber in restoration force so that thin layers consisting of them are provided in order to secure sealing property in an intermediate layer. The thermalplastic elastomer, etc., are the ones by which a production process is executed in the same way as that of a easing 3 as the material quality of the stopper body so that the cap 1 is finished by molding the casing 3 and, after that, executing injection- molding at every thin layer in which the stopper body 2 is provided.</p> |
