DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0044] Reference will be now made in detail to the preferred embodiments of the present invention with reference to the accompanying drawings.

[0045] First, in connection with adding reference signs to the constituent elements in each of the drawings, the same constituent elements have the same reference numerals as far as possible even though they are illustrated in different figures.

[0046] FIG. 4a-FIG. 4b show the construction of a nozzle according to a first embodiment of the present invention, in which FIG. 4a is a cross-sectional side view and FIG. 4b is a view for showing a service condition,

[0047] First, a nozzle according to the present invention is applied to a dispenser, which includes includes a driving part 10, a coupling part 20 mounted on the bottom surface of the driving part 10, a nozzle part 30 mounted at the lower portion of the coupling part 20, and a syringe part 40 mounted on a side surface of the coupling part 20, as described above, such that a tappet, which carries out vibration motion and has a leading end portion 101 formed in a conical shape, is mounted on the lower end of the driving part 10 so as to be exposed and inserted into the nozzle part 30 through the coupling part 20, and the nozzle part 30 is provided with a nozzle on the bottom surface thereof. A nozzle 110 according to the present invention includes a funnel-shaped accommodation part 111 formed for maintaining a predetermined gap G from an outer circumferential surface of the leading end portion 101 of the tappet 100, a funnel groove 112 formed in the center of a bottom surface 111a of the funnel-shaped accommodation part 111 such that the leading end portion 101 of the tappet 100 is inserted into the funnel groove 112 by a predetermined length, and an injection hole 113 penetratingly formed in the center of the funnel groove 112.

[0048] In the nozzle 110 as structured above, liquid to be dispensed is discharged to the outside through the injection hole 113 as the tappet 100 moves forwards such that the front tip of the leading end portion 101 is inserted into the funnel groove 112 after the liquid to be dispensed is charged into the accommodation part 111 and the funnel groove 112 of the nozzle 110 through a gap around the tappet 100 (the first space part 35, see FIG. 2)

[0049] After the injection operation, the liquid to be dispensed staying in the gap G is introduced into the funnel groove 112 with speed at the moment when the tappet 100 moves backwards.

[0050] Therefore, the liquid to be dispensed is introduced into the funnel groove 112 through the accommodation part 111 with speed when the tappet 100 moves up and down such that a quantitative amount of the liquid to be dispensed can be injected, thereby improving dispensing quality.

[0051] FIG. 5a-FIG. 5b show the construction of a nozzle according to a second embodiment of the present invention, in which FIG. 5a is a cross-sectional side view and FIG. 5b is a plane view.
