     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0024]    Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members. 
         [0025]      FIG. 1  is an exploded perspective view illustrating a configuration of a dispenser container according to an exemplary embodiment, and  FIG. 2  is a cross-sectional view illustrating a configuration of a dispenser container according to an exemplary embodiment. 
         [0026]    Referring to  FIGS. 1 to 2 , a dispenser container according to an exemplary embodiment may include a container body  100 , a pumping member  200 , and button member  500 . 
         [0027]    The container body  100 , where contents is stored, includes a piston  110  which ascends according to contents use at a lower portion thereof. 
         [0028]    Drawings illustrate a piston  110  is provided at the container body  100 ; however, any containers which can store contents, such as a tube container or a blow-forming container, are possible. 
         [0029]    The pumping member  200  coupled to an upper portion of the container body  100  and discharging contents stored in the container body through a pumping operation includes a pump housing  210 , a piston rod  220 , a seal cap  230  and an elastic body  240 . 
         [0030]    The pumping housing  210  closes an opened upper portion of the container body  100  and is coupled thereto. The pumping housing  210  includes a cylinder  211  having a content inflow hole  212  formed at a lower end thereof such that contents stored in the container body  100  may flow in, wherein at an inner lower portion of the cylinder  211  is installed a check valve  213  which opens/closes the content inflow hole  212  according to an operation of a button member  300 . 
         [0031]    Furthermore, at an inner circumferential surface of the pump housing  210  is provided a protrusion  214  which limits the ascent of a seal cap  230  so as to prevent the seal cap  230  from being separated from the pump housing  210  in a process that the seal cap  230  ascends along while a button member  300  is ascending. 
         [0032]    Furthermore, at an upper end of the pump housing  210  is provided a securing groove  215  such that a lower end of an elastic body  240  moving the button member  300  to an upward direction may be secured therein. 
         [0033]    Meanwhile, at an outer side of the pump housing  210  is detachably coupled an over cap  400  encasing the button member  300 , wherein the over cap  400  is coupled to the pump housing  210  at a normal state and thereby prevents malfunction of the button member  300 , thus preventing foreign material from entering through a discharging hole  310 . 
         [0034]    The piston rod  220  is coupled to a coupling part  320  of the button member  300  and moves along according to the ascent/descent of the button member  300 . A lower portion of the piston rod  220  is disposed at an inner side of the cylinder  211 , making it possible to move contents having flowed in the cylinder  211  to an upper portion thereof. For this purpose, the piston rod  220  includes a content movement passage (S) where contents move at an inner side thereof, such that the contents that flowed into the cylinder  211  may move to a discharging hole  310  of the button member  300 . 
         [0035]    Furthermore, the piston rod  220  includes a contents movement hole  221  at a lower portion of the side thereof such that contents may move to the contents movement passage (S). 
         [0036]    The seal cap  230  is disposed, encasing the piston rod  220 , and changes inner pressure of the cylinder  211  as moving along an inner wall of the cylinder  211  when the button member  300  ascends/descends. At an inner side of the seal cap  230  is provided an opening/closing tip  231  which opens/closes the content movement hole  221 , wherein the opening/closing tip  231  is configured to be closely contacted to an outer circumferential surface of the piston rod  220  at a lower portion of the content movement hole  221  and then separated in a narrow margin when the piston rod  220  descends according to pressurization of the button member  300 , thereby forming a space where contents move and at the same time, and at the same time, opening the content movement hole  221 . 
         [0037]    The seal cap  230  is possible for flexible osculation when it is closely contacted to an outer circumferential surface of the piston rod  220 , and it is preferable to be made of soft material so as to move easily along an inner wall of the cylinder  211 . 
         [0038]    Meanwhile, at an outer circumferential surface is provided a support protrusion  232  supported by a protrusion  214 , wherein the support protrusion  232  meets a lower end of the protrusion  214  in a process that the seal cap  230  ascends and limits the ascent of the seal cap  230 . 
         [0039]    The elastic body  240  is disposed between the pump housing  210  and the button member  300  and provides an elastic force such that the button member  300  may move to an upward direction. A lower end of the elastic body  240  is secured to a securing groove formed at an upper end of the pump housing  210 , and an upper end thereof is supported by a support groove formed at an inner side of the button member  300 . 
         [0040]    The button member  300 , which is disposed at an upper portion of the pumping member  200  and delivers a pressure generated by a user&#39;s control to the pumping member  200  and then causes a pumping operation, includes a discharging hole  310  such that contents can be discharged according to the pumping operation of the pumping member  200 . 
         [0041]    A coupling part  320  to which the piston rod  220  is coupled extends in a downward direction at an inner side of the button member  300 . The coupling part  320  pressurizes the seal cap  230  when the button member  300  descends and guides a downward movement of the seal cap  230 , and further connects the content movement passage (S) and the discharging hole  310  such that contents can move to the discharging hole  310  through the content movement passage (S). 
         [0042]    Meanwhile, at inner side of the button member  300  is provided a support groove  330  which supports an upper end of the elastic body  240 . 
         [0043]    Hereinafter, an operational state of a dispenser container according to an exemplary embodiment will be described with reference to  FIGS. 3 and 4 .  FIGS. 3 and 4  are views illustrating an operational state of a dispenser container according to an exemplary embodiment. Referring  FIGS. 3 and 4 , when the button member  300  is pressurized in a state of contents having flowed into a cylinder  211 , a piston rod  220  coupled to the button member  300  descends along with the button member  300 . At this moment, in a process that the button member  300  descends, a coupling part  320  pressurizes a pressurization face  233  of a seal cap  230  and thereby the seal cap  230  descends as well. 
         [0044]    As described above, when the piston rod  220  and the seal cap  230  descend, an inner pressure of the cylinder  211  changes and thereby contents having flowed into the cylinder  211  move to a content movement passage (S) through a content movement hole  221  and are discharged to the outside through a discharging hole  310 . At this time, the opening/closing tip  213  is separated with a narrow margin from an outer circumferential surface of the piston rod  220  when the piston rod  220  descends according to pressurization of the button member  300 . 
         [0045]    Next, when the button member  300  releases pressurizing, the button member  300  ascends by an elastic force of an elastic body  240 . At this time, a piston coupled to the button member  300  ascends together, and a lower portion of the piston rod  220  meets an opening/closing tip  213  of the seal cap  230  while the piston rod  220  is ascending, and thereby moves the seal cap  230  up in an upward direction. 
         [0046]    When the seal cap  230  ascends as in the above, a check valve  213  opens a content inflow hole  212  and thereby contents stored in the container body  100  flow into the cylinder  211 . 
         [0047]    Hereafter, referring  FIG. 5 , a dispenser container according to another exemplary embodiment.  FIG. 5  is a cross-sectional view illustrating a dispenser container according to another exemplary embodiment. Referring  FIG. 5 , a dispenser container according to an exemplary embodiment includes a container body  100 , a pumping member  200 , and a button member  300 . Since the container body  100  has the same structure and function with an exemplary embodiment as described in the above, a pumping member  200  and a button member  300  are to be described hereafter. 
         [0048]    The pumping member  200 , coupled to the container body  100  and discharging contents stored in the container body  100  through a pumping operation, includes a pump housing  210 , a piston rod  220  a seal cap  230  and an elastic body  240 . 
         [0049]    Since, the pump housing  210 , as described in the above, is the same in its structure and function with that of an exemplary embodiment, detailed description will be omitted. 
         [0050]    The piston rod  220  is coupled to a coupling part  320  of the button member  300  and moves along with the ascent of the button member  300 . In a general pump structure, when contents are discharged, the contents pass through a content movement passage provided at an inner side of a piston rod through content movement hole provided at an inner side of a piston rod; however, according to another exemplary embodiment, it is characterized that contents are discharged through a space formed between a piston rod  220  and a seal cap  230 , not that contents moves into an interior of the piston rod  220 . For this purpose, the seal cap  230  is configured to encase the piston rod  220  and to form a space with an inner circumferential surface thereof separated in a predetermined distance from an outer circumferential surface of the piston rod  220 . 
         [0051]    Meanwhile, at a lower inner side of the seal cap  230  is provided an opening/closing tip  231  which opens/closes a lower end of the content movement passage (S), wherein, when in a normal state, the opening/closing tip  231  is closely contacted to a lower outer circumferential surface of the piston rod  220  and prevents contents from moving to the content movement passage (S) and, when the piston rod  220  descends according to a pressurization of the button member  300 , the opening/closing tip  231  is separated in a narrow margin from an outer circumferential surface of the piston rod  220  and opens the content movement passage (S), thereby making contents move to a upper portion thereof. 
         [0052]    The seal cap  230  is preferred to be made of soft material so as to have a flexible contact when the seal cap  230  is closely contacted to an outer circumferential surface of the piston rod  230  and to move easily along an inner wall of a cylinder  211 . 
         [0053]    Meanwhile, at an outer circumferential surface of the seal cap  230  is provided a support protrusion  232  which is supported by the protrusion  214 , wherein the support protrusion  232  meets a lower end of the protrusion  214  while the seal cap  230  is ascending and limits the seal cap  230  ascending. 
         [0054]    The elastic body  240  is disposed between the pump housing  210  and the button member  300  and provides an elastic force such that the button member  300  move in an upward direction. A lower end of the elastic body  240  is secured to a securing groove  215  formed at an upper end of the pump housing  210 , and an upper end thereof is supported by a support body  350  provided at an inner side of the button member  300 . 
         [0055]    The button member  300 , disposed at an upper portion of the pumping member and delivering a pressure generated by a user&#39;s manipulation, thereby causing a pumping operation, comprises a discharging hole  310  such that contents can be discharged by a pumping operation of the pumping member  200 . 
         [0056]    A coupling part  320 , where the piston rod  220  is coupled, extends to a downward direction at an inner side of the button member  300 , wherein the coupling part  320  is characterized to pressurize the seal cap  230  when the button member  300  descends and guide the seal cap  230  to move in a downward direction. 
         [0057]    The coupling part  320  has a configuration that the length of a front face part disposed to a direction of the discharging hole  310  is short, and the length of a rear face is long. Since the front face part is short, it is possible to prevent interference when contents are discharged through an upper portion of the content movement passage (S). Meanwhile the rear face part, whose length is long, pressurizes a pressurization face  233  of the seal cap  230  and moves the seal cap  230  to a downward direction. 
         [0058]    Meanwhile, at an inner side of the button member  300  forms a space where an upper portion of the seal cap  230  ascends/descends, and further comprises a connection tube  340  which connects the content movement passage (S) and the discharging hole  310 . Therefore, it is preferable that an upper portion of the seal cap  230  is formed of a shape of a piston, ascending/descending in a close contact with an inner circumferential surface of the connection tube  340  so as to prevent the leakage of contents which move to the discharging hole  310  through the content movement passage (S). 
         [0059]    Meanwhile, at an inner side of the button member  300  is provided a support body  350  which supports an upper end of the elastic body  240 . 
         [0060]    The configuration of the rest is the same as described in an exemplary embodiment; hence, detailed description is omitted. 
         [0061]    Hereinafter, an operational state of a dispenser container according to an exemplary embodiment will be described with reference to  FIGS. 6 and 7 .  FIGS. 6 and 7  are views illustrating an operational state of a dispenser container according to an exemplary embodiment. Referring  FIGS. 6 and 7 , when the button member  300  is pressurized in a state of contents having flowed into a cylinder  211 , a piston rod  220  coupled to the button member  300  descends along with the button member  300 . At this moment, in a process that the button member  300  descends, a coupling part  320  pressurizes a pressurization face  233  of a seal cap  230  and thereby the seal cap  230  descends as well. 
         [0062]    As described in the above, when a piston rod  220  and a seal cap  230  descend, an inner pressure of a cylinder  211  changes, and then contents having flowed into the cylinder  211  move to a content movement passage (S) and are discharged to the outside through a discharging hole  310 . At this time, the opening/closing tip  231  is closely contacted to a lower outer circumferential surface of the piston rod  220  and prevents contents from moving to the content movement passage (S). After that, as the piston rod  220  first descends in a process that a coupling part  320  of the button member  300  is separated from a pressurization face  233  of the seal cap  230 , the opening/closing tip  231  gets separated with a small margin from an outer circumferential surface of the piston rod  220  and opens the content movement passage (S), making the contents move to an upper portion thereof through the content movement passage (S). 
         [0063]    Next, when pressurization of the button member  300  is released, the button member  300  ascends by an elastic force of an elastic body  240 . At this time, a piston coupled to the button member  300  ascends together, and a lower portion of the piston rod  220  meets an opening/closing tip  213  of the seal cap  230  while the piston rod  220  is ascending, and thereby moves the seal cap  230  up in an upward direction. 
         [0064]    When the seal cap  230  ascends as in the above, a check valve  213  opens a content inflow hole  212  and thereby contents stored in the container body  100  flow into the cylinder  211 . 
         [0065]    The presently described embodiments do not have a structure of a conventional complicated pumping member, but have a structure of a pumping member simply comprising a pump housing, a piston rod, a seal cap and an elastic body. Therefore, it is possible not only to reduce a manufacturing expense but shorten an overall manufacturing time through simplifying the assembly procedure. 
         [0066]    As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been used herein, these are only intended to describe exemplary embodiments and are not intended to limit the meanings of the terms or to restrict the scope of the accompanying claims. Therefore, those skilled in the art will appreciate that various modifications and other equivalent embodiments are possible from the above embodiments. Accordingly, the scope of the accompanying claims should be defined by the technical spirit of the description.
