The present invention relates to a plastic tank, which has a configuration that a fusion protrusion of an upper shell and a lower shell constituting the plastic tank are thermally bonded to each other to form an inner surface of the tank. Accordingly, as a notch of an inner bead formed by the bonding of the fusion protrusion is formed to be located inside the tank with respect to an inner surface of the upper shell and an inner surface of the lower shell, it is possible to prevent damage or breakage to the inner surface of the plastic tank due to cracks in the notch.

    본 발명은 플라스틱 탱크에 관한 것으로, 플라스틱 탱크를 구성하는 상부쉘 및 하부쉘의 융착돌기가 서로 열융착으로 결합되어서 탱크의 안쪽면을 형성하는 구성으로, 융착돌기의 결합에 의해 형성된 내측비드의 노치가 상부쉘의 안쪽면 및 하부쉘의 안쪽면을 기준으로 탱크의 내측에 위치하도록 형성됨에 따라, 플라스틱 탱크의 안쪽면이 노치의 크랙으로 손상되거나 파손되는 현상을 방지할 수 있도록 된 것이다.
