Figure 9 is a view illustrating an operation procedure of a nozzle of a dispenser pump button according to another embodiment of the present invention.
As shown in Figures 6 to 9, the nozzle structure of the dispenser pump button according to another embodiment of the present invention comprises an inner nozzle 500, an outer nozzle 60, an elastic member 700, and an elastic member fixing part.
The inner nozzle 500 is formed in a cylindrical shape which is coupled to the discharge portion 11 of the dispenser pump button 10 and comprises a plurality of content inflow holes 510 which are formed at the rear end at regular intervals for the sake of inflow of contents which are discharged through the discharge portion 11.
At the inner nozzle 500 is provided a blocking rod 520 which protrudes from the center of the end of the rear side to the front side for thereby opening and closing the discharge holes 621 as the outer nozzle 600 moves forwards or backwards. It is preferred that at the end portion of the blocking rod 520 is provided a protrusion 521 which protrudes to the outside of the outer nozzle 600 in order to prevent the contents from gathering at the space formed by the blocking rod 520 and the outer nozzle 600.
Since the protrusion 521 is formed at the locking rod 520, it is easy to recognize the opening and closing of the nozzle from the outside when the nozzle moves.
In the present invention, there is provided an engaging groove 530 at the inner surface of the inner nozzle 500 for securing the elastic member fixing part 800. To the engaging groove 530 is engaged the engaging protrusion 821 of the elastic member fixing part 800 for the engagement with the elastic member fixing part 800.
The outer nozzle 600 is engaged surrounding the blocking rod 520 and moves forwards or backwards by the pressure of the contents "a" or the elastic force of the elastic member 700 and comprises a mounting part 61 and a content movement tube 620.
The mounting part 610 is mounted at the inner end of the inner nozzle 500 and supports the elastic member 700. At the front side of the same is mounted the elastic member 700 for thereby pressurizing the elastic member 700 while the contents is discharged, so the elastic member 700 is contracted. When the discharge of the contents stop, the outer nozzle 600 moves backwards by the elastic force of the elastic member 700.
In the present invention, the mounting part 610 is formed in a cylindrical shape, and the front end 611 and the end portion 612 of the cylindrical mounting part 610 are formed in the piston structure which comes into contact with the wall surface of the inner side of the elastic member fixing part 800. With the above mentioned construction, the movements of the outer nozzle 600 can be prevented, which results in constant discharges while preventing the leak of the contents.
The content movement tube 620 extends from the center of the front side of the mounting part 610 to the forward side for thereby forming a passage through which the contents "a" inputted through the content inflow holes 510 of the inner nozzle 500 move and comprises a discharge hole 621 at the end portion, which is opened and closed by the blocking rod 520 in order for the inputted contents "a" to be discharged to the outside.
The elastic member 700 is engaged surrounding the outer nozzle 600 and moves backwardly the outer nozzle 600, one end of the elastic member 700 being mounted at the mounting part 610 of the outer nozzle 600, the other end of the same being mounted at the elastic member mounting shoulder 810 of the elastic member fixing part 800.
The elastic member 700 is contracted by the movements of the outer nozzle 600 which moves forwards by the pressure of the contents "a" when the button 10 is pressed, and the elastic member 700 is released as the pressed button 10 is released for thereby providing the elastic force to the outer nozzle 600, so the outer nozzle 600 can move backwards.
The elastic member fixing part 800 is engaged surrounding the outer nozzle 600 and the elastic member 700 for thereby fixing the elastic member 700. There is provided an elastic member mounting shoulder 810 which is bent in an inward direction in order for the elastic member 700 to be fixed.
The elastic member mounting shoulder 810 supports one side of the elastic member 700 when the outer nozzle 600 moves forwards, by which the elastic member 700 can be contracted.
At the rear side of the elastic member fixing part 800 is provided an engaging part 820 which is engaged to the inner side of the inner nozzle 500. It is preferred that at the engaging part 820 is provided an engaging protrusion 821 which corresponds to the engaging groove 530 for the sake of the engagement with the inner nozzle 500.
At the outer surface of the elastic member fixing part 800 is provided an engaging protrusion 830 engaged to the engaging groove 12. For an easier engagement to the engaging groove 12 formed at the discharge portion 11 of the dispenser pump button 10 through the engaging protrusion 830, the nozzle is made in the nozzle type, so the present invention can be well applied to various designs of buttons. Only the nozzle can be assembled and inspected during the manufacture process for thereby achieving lowered defect ratios and enhancing productivity.
In the nozzle of the present invention, the inner nozzle 500 and the elastic member fixing part 800 are engaged by the engaging groove 530 formed at the inner surface of the inner nozzle 500 and the engaging protrusion 821 formed at the outer surface of the elastic member fixing part 800, so the inner nozzle 500, the outer nozzle 600, the elastic member 700 and the elastic member fixing part 800 can be made in a module type.
The operations of the nozzle of a dispenser pump button according to another embodiment of the present invention will be described with reference to Figure 9.
As shown in Figure 9, the contents "a" is discharged through the discharge portion 11 when a user presses the button 100 in the operations of the nozzle of the dispenser pump button according to another embodiment of the present invention. At this time, the contents "a" is inputted into the content movement tube 620 of the outer nozzle 600 through the content inflow hole 510.
The outer nozzle 600 is pressurized by the contents "a" while the contents "a" moves into the content movement tube 620, and the outer nozzle 600 moves forwardly by the pressure of the contents "a". When the outer nozzle 600 moves forwards, the discharge hole 621 which remains closed by the blocking rod 520 of the inner nozzle 500, is opened, so the contents "a" can be discharged to the outside through the discharge hole 621.
When the user releases the pressed button 10, the movements of the contents "a" stop. At this time, the elastic member 700, which was contracted by the forward movement of the outer nozzle 600 returns to its initial state for thereby providing elastic force to the outer nozzle 600, so the outer nozzle 600 can move backwards. When the outer nozzle 60 moves backwards, the discharge hole 621 is closed by the blocking rod 520 of the inner nozzle 500, so the discharge of the contents "a" is blocked.
