A pump dispenser includes a tube seat engaged in a rotating lid of the lotion bottle; a pump arranged on a bottom of the tube seat for drawing the lotion unilaterally; a through hole arranged in the tube seat and communicated with the pump; a pipe movably received in the through hole to be configured for guiding the lotion in the pump; a press head placed over an opening of the pipe exposed out of the top of the through hole to be configured for guiding the lotion in the pipe out; at least one upper trapezoidal body opening upwards and at least one lower trapezoidal body opening downwards arranged on the inner surface of the through hole; and at least one protrusion arranged on the outer surface of the pipe. The protrusion moves into or out of the bottom of the lower trapezoidal body by rotating the head press for preventing or permitting the press head from moving upwards such that the lotion bottle is convenient to be carried. The protrusion moves into or out of the top of the upper trapezoidal body by rotating the head press for preventing or permitting the press head from moving downwards such that the lotion will not be drawn out when the press head is accidentally pressed.
