PROBLEM TO BE SOLVED: To provide a plastic container provided with sufficient waterproof and oilproof properties. SOLUTION: A packing material like a lower hardness rubber than at least a plastic vessel is directly attached by baking at least at one side face 4 of the connection face of the plastic container provided with oppositely arranged connection faces. When mutual connection faces of the plastic container are joined together, the packing material put on at least one side face 4 of the connection faces comes into contact with the other connection face and by further pressing the packing to squash it, the container inside is hermetically sealed. The hardness of the packing is made lower than at least the plastic container so that the packing is deformed before the plastic container is deformed to prevent the deformation, cracks, fissures of the container. And by directly baking the packing 10 on the connection face of the plastic container, the packing can be prevented from dropping out of a fitting groove 2. |
