PURPOSE:To reduce the bulging of a container and to increase rigidity by forming the container with a thermoplastic synthetic resin in which a given amount of fine glass fibers is kneaded. CONSTITUTION:A container is formed with a thermoplastic synthetic resin in which 10-20% of fine glass fibers are kneaded. By using the container 2 made of polypropylene kneaded with fine glass fibers whose length is 3-4mm and diameter is 3mum, the bulging of the container caused by internal pressure is reduced to 1/2 or less compared with that of a conventional one, and rigidity is also increased. By increasing rigidity, the strength in the same thickness against internal pressure is increased. Since heat resistance is increased, deformation caused by heat resistant fastening is decreased. Since shrinkage is small, dimension stability is increased. |
