A sprayer cap structure.

摘要

This invention relates to an improved sprayer cap structure associated with a neck portion (6) of a bottle-shaped container (1) which comprises an inner plug (10) integrally formed adjacently with first and second hollow cylindrical portions (18, 19) in a top-walled cylindrical section (11) perforated with a first hole (20) communicating with the bottom of the container through a pipe (24), also formed with a first valve chamber (26) provided with a blocking valve at the upper position thereof and with a check valve at the lower position thereof, perforated with a second hole (21) and a third hole (22) spaced longitudinally, and formed with a second valve chamber (27) under the second hole (21), provided with a blocking valve at the upper position thereof; a nozzle unit (35) formed with a spinner slot (44) capable of communicating with the first and second holes (20, 21) of the inner plug (10), perforated with a first nozzle hole (42) substantially at the center of the spinner slot (44) of the inner cylindrical section (36), further perforated with a second nozzle hole (43) capable of communicating with the third hole (22) of the inner plug (10) adjacent to the first nozzle hole (42); and a cylindrical cover unit (48) associated I immovably with the container body (1). Thus, the spraying operation and the streaming operation can be simply and reliably switched.
