<P>PROBLEM TO BE SOLVED: To provide the nozzle opening/closing structure of a discharge container, which is simple, and opens and closes a discharge opening on a nozzle member by sliding up and down a cover cap accurately and stably to avoid the clogging of the discharge opening. <P>SOLUTION: The nozzle opening/closing structure comprises the nozzle member 12 which is fitted on a stem 14 projecting on the upper end of a container body 11 and discharges contents when pressed down, a guide cylinder 17 which encircles the stem 14 and guides the vertical sliding move of the nozzle member 12 along an inner peripheral surface 16, and the cover cap 20 which slides up and down, as it is guided along the outer peripheral surface 18 of the guide cylinder 17, to open and close the discharge opening 12 by shifting from a position for covering the discharge opening 13 on the nozzle member 12 to a position for matching a cutout opening 19 to the discharge opening 13. The guide cylinder 17 has a tapered surface 18 widening downward, and the cover cap 20 has elasticity that makes it possible to deform to widen. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
