This invention relates to an improved sprayer cap structure associated with a neck portion of a bottle-shaped container for providing a liquid spraying operation or a liquid streaming operation. The sprayer cap includes an inner plug integrally formed adjacently with first and second hollow cylindrical portions in a top-walled cylindrical section. The cylindrical section is perforated with a first hole communicating with the bottom of the container through a pipe, and is also formed with a first valve chamber provided with a blocking valve at the upper position thereof and with a check valve at the lower position thereof. The cylindrical section further is perforated with a second hole and a third hole spaced longitudinally, and formed with a second valve chamber under the second hole, the second valve chamber being provided with a blocking valve at the upper position thereof. A nozzle unit is formed with a spinner slot capable of communicating with the first and second holes of the inner plug. The nozzle unit is perforated with a first nozzle hole substantially at the center of the spinner slot of the inner cylindrical section, and further perforated with a second nozzle hole capable of communicating the third hole of the inner plug adjacent to the first nozzle hole. A cylindrical cover unit is associated immovably with the container body.
