Figure 5 is a view illustrating an operation procedure of a nozzle of a dispenser pump button according to a preferred embodiment of the present invention.
As shown in Figures 1 to 5, the nozzle structure of the dispenser pump button according to a preferred embodiment of the present invention comprises an inner nozzle 100, an outer nozzle 200, an elastic member 300, and an elastic member fixing part 400.
The inner nozzle 100 is formed in a cylindrical shape which is coupled to a discharge portion 11 of the dispenser pump button 10. From the inner surface of its rear end to the center are provided a plurality of extensions 110 at regular intervals while forming a content inflow hole 120 in order for the contents discharged through the discharge portion 11 to flow inside.
At the inner nozzle 100 is provided a blocking rod 130 which protrudes in a forward direction from the center portion coming into contact with the plurality of the extensions 110, so the discharge hole 221 can be opened and closed as the outer nozzle 200 moves forwards or backwards.
In the present invention, at an outer surface of the inner nozzle 100 is provided an engaging protrusion 150 for the sake of an engagement to the discharge portion 11. The discharge portion 11 can be easily assembled with the aid of the engaging protrusion 150. At this time, at the inner surface of the discharge portion is preferably provided an engaging groove 12 for the sake of an engagement to the engaging protrusion 150.
At an inner surface of the inner nozzle is provided an engaging groove 140 to which an elastic member fixing part 400, which will be described later, is coupled.
Here, the outer nozzle 200 comprises a mounting part 210 which surrounds the blocking rod 130 and is secured in the interior of the inner nozzle 100 and moves forwards or backwards by the pressure of the contents "a" or the elastic force of the elastic member 300 and is mounted at the inner end of the inner nozzle 100, and a content movement tube 220 which extends from the center of the mounting part 210 and forms a passage through which the contents "a" move.
The mounting part 210 mounts at the inner end of the inner nozzle 100 when the outer nozzle 200 moves backwards by the elastic force of the elastic member 300 for thereby limiting the movable range when the outer nozzle 200 moves backwards. At the mounting part 210 are preferably provided a plurality of elastic member parts 211 which are spaced apart at regular intervals for the elastic member 300 to be supported.
The content movement tube 220 serves to form a passage through which the contents inputted through the content inflow hole 120 of the inner nozzle 100 to move, and at the end of the same is provided a discharge hole 221 which is opened and closed by the blocking rod 130 in order for the inputted contents to be discharged to the outside.
The elastic member 300 is engaged surrounding the outer nozzle 200 and makes the outer nozzle move backwards, one side of the elastic member being mounted at the elastic member support part 21 of the outer nozzle 200, the other side of the same being mounted at an elastic member mounting shoulder 320 of the elastic member fixing part 400.
The elastic member 300 is contracted by the movement of the outer nozzle 200 which moves forwards by the pressure of the contents "a" at the time the button 10 is pressed, and is released when the pressed button 10 is released, for thereby providing an elastic force to the outer nozzle, by which the outer nozzle 200 can move backwards.
The elastic member fixing part 400 is engaged surrounding the outer nozzle 200 at the inner side of the inner nozzle 100 for thereby fixing the elastic member 300 and comprises an elastic member mounting shoulder 420 which is inwardly bent for the purpose of fixing the elastic member 300.
The elastic member mounting shoulder 420 serves to support one side of the elastic member 300 when the outer nozzle 200 moves forwardly, for thereby allowing the elastic member 300 to be contracted.
At the elastic member fixing part 400 is preferably provided an engaging protrusion 410 corresponding to the engaging groove 140 for the engagement to the inner nozzle 100.
The nozzle of the present invention has features in that the inner nozzle 100 and the elastic member fixing part 400 are engaged by the engaging groove 140 formed at the inner surface of the inner nozzle 400 and the engaging protrusion 410 formed at the outer surface of the elastic member fixing part 400, so the inner nozzle 100, the outer nozzle 200, the elastic member 300 and the elastic member fixing part 40 can be integrated in a module type.
The nozzle of the present invention is made in a module type which make it possible to easily engage to the engaging groove 12 formed at the discharge portion 11 of the dispenser pump button 10 with the aid of the engaging protrusion 150 formed at the outer surface of the inner nozzle 100, so the present invention can be well applied to various designs of buttons, and only the nozzle can be assembled and inspected during the manufacture process, the detect ratio can be lowered.
The operations of the nozzle of the dispenser pump button according to a preferred embodiment of the present invention will be described with reference to Figure 5.
As shown in Figure 5, during the operation procedures of the nozzle of the dispenser pump button according to a preferred embodiment of the present invention, when a user presses the button 10, the contents "a" starts discharging through the discharge portion 11. At this time, the contents "a" is inputted into the content movement tube 220 of the outer nozzle 200 through the content inflow hole 120.
The outer nozzle 200 moves forwards by the pressure of the contents "a" as pressure is applied to the outer nozzle 200 by the contents "a" while the contents "a" is inputted into the content movement tube 220. When the contents move forwards, the discharge hole 221, which remains closed by the blocking rod 130 of the inner nozzle 100, is opened, so the contents "a" can be discharged to the outside through the discharge hole 221.
When the user releases the pressed state of the button 10, the movement of the contents "a" stops, and the elastic member 300 returns to its initial position, thus providing electric force to the outer nozzle 200, so the outer nozzle 200 moves backwards. When the outer nozzle 200 moves backwards, the discharge hole 221 is closed by the blocking rod 130 of the inner nozzle 100 for thereby preventing the contents "a" from being discharged.
As the present invention may be embodied in several forms without departing from the scope of the appended claims, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims.
