ABSTRACT:
A plastic cap is provided which is capable of assuring a high sealing property and is advantageous for protection of the environment because of being readily subjectable to disposal of waste or burning treatment after using a container. The plastic cap comprises a drum part covering the mouth part of a container and sealing material and a top plate positioned on a top wall of the drum part, in which the drum part has, on the inner wall thereof, a protrusion part or wedge-shaped part to be engaged with an annular protrusion on the outer periphery of the container mouth part. A window part opens at the center part of the top wall of the cap drum port, and the outer edge of the window part and the lower part of the top plate are connected through several bridged parts. The top plate has at least a larger area than the window part and covers the window part and top wall and the bridged parts are broken by adding a force in a predetermined direction to the top plate to separate the top plate when using the medicament.
