Plastic Thread Design

Dear sir,

I would like to know basic points to design threads at the lid Id for plastic parts and you can find the attached file.

If the lid is tightened, the thread should withstand 0.3 kg/cm2 pressure and at the same time pressure should not leak.

Kindly suggest me anybody regarding this thread design.

Thanking you,

Regards,
