A rotary cover for closing the axial opening of a hollow-cylindrical body, a rotary cap and said body having corresponding cam threads, which cause an axial displacement of the rotary cap relative to the body when the rotary cap is rotated. Axial sides of the rotary cap and of the body, which face each other, extend in a plane inclined by a specific angle .alpha. relative to the axis of the body. These axial sides of the rotary cap and of the body are in alignment with each other in the closed position of the rotary cover.
