PURPOSE:To obtain an internal pressure container having pressure resistance, low temperature toughness, high temperature dimension stability, chemicals resistance, and moldability by molding into a container or composition formed by blending plastics with a plate-shaped inorganic filler, for example, glass flake. CONSTITUTION:A polyester resin, for example, a PBT (polybutylene terephthralate) resin is the most suitable as plastics blending a plate-shaped inorganic filler. For example, a glass flake 20%-blended PBT resin is injection- molded from a gate at the center of a container bottom part 1 to obtain a molding formed by integrating the bottom part 1 and a barrel part 2. Supersonic wave welding is applied to the molding and a separately molded shoulder part 3 to obtain an internal pressure container. The container in combination with a sealing means, for example, a screw-in or mounting cap system injection nozzle, etc., can be used in an internal pressure condition containing a content such as a drug. or a propellant. |
