BACKGROUND 
     (a) Technical Field 
     The present invention relates to an open and close apparatus of a button sliding type for a liquid instrument, and more particularly, to an open and close apparatus of a button sliding type for a liquid instrument which is opened and closed by sliding a pump button provided on the liquid instrument without separating a lid when using the liquid instrument. 
     (b) Background Art 
     Generally, the contents is received in an instrument main body and in order to avoid a spoilage of the contents due to an air contact a discharger is provided on an upper end thereof for discharging a small amount of the contents while being connected to the instrument main body. Specially, the discharger has been configured as a pump type discharging structure for discharging easily the contents so that a user presses a knob for the contents to be pumped and discharged automatically. 
     In general, in the pump type liquid instrument, a separate compression pump is provided on an instrument body and a separate piston is inserted inside the instrument, and a pressure difference is produced inside the instrument, which is caused from the compressed pump, and the contents is discharged and the piston rises to as amount as the discharged space to push upward the contents. 
     Furthermore, in the liquid instrument configured as the pump type discharging structure, a knob of a pump device operation unit for discharging a predetermined amount of the contents in a liquid state or gel phase is compressed unintentionally to discharge and waste the contents. Accordingly, a whole pump including a nozzle is covered with a lid and the lid is opened when using the instrument for the nozzle to be exposed. 
     However, the lid is connected in a screw type manner so that the lid is opened and closed through its rotation and thus the lid has to be rotated inconveniently at several times for opening and closing it depending on the number of threads, and further the opened lid may be mishandled or lost, or dropped to be damaged. 
     Further, in Korean Utility Model Application No. 2003-35413 and Korean Utility Model Application No. 2003-38063, a liquid instrument of a nozzle appearing type has been disclosed, in which the nozzle is raised to be exposed to the outside of the lid by rotating a body or the lid while not separating the lid, and the nozzle is lowered to be concealed to the inside of the lid by reverse-rotating the body or the lid so that when not using the liquid instrument, a nozzle button is avoid being pressed intentionally for the contents to be discharged. 
     In the liquid instrument as configured in the forgoing, when the nozzle is compressed from an upper side to a lower side, the contents is discharged sideward. Here, since the contents is injected by exposing the nozzle over the lid, even if injection power is not great, a pumping force is great in an initial state of compressing the nozzle and thus the contents is injected to a relatively long distance, however, at a final state of compressing the nozzle the pumping force is small and thus the contents is dropped on the lid wherein the contents dropped on the lid is emerged into a groove between the lid and the nozzle to be spoiled, or the contents is coated with various external substances to contaminate the surroundings.

     As shown in the drawings, a liquid instrument of the present invention comprising a container  10  for receiving the contents in a liquid state or a gel phase, and a discharging pump  50  which is connected to the upper inside of the container  10  and discharges the contents through an external pressure, may include a shoulder  20  connected to an upper part of the container  10 , a button body  30  inserted into the shoulder  20  and movable vertically, and a button  40  which is connected to an upper surface of the button body  30  and allows the button body  30  not to be operated while opening and closing the contents pumping hole  31  of the button body  30 . 
     The button body  30  is configured such that its lower surface is opened and its upper surface is concaved, and further a sliding hole  32  formed symmetrically on both sides so that a plurality of leg portions of the button  40  are inserted and slid therein. Further, a side wall  32   a  is formed on the respective side of the sliding hole  32  so that the side wall is stumbled-connected to a stumbling protrusion  42  formed on a lower end of the leg portion of the button  40  and a contents pumping hole  31  is formed on a middle of the upper surface. 
     Here, a guide cap  33  is formed forward on the upper surface of the button body  30  for guiding the sliding of the button  40 . 
     A sliding limitation groove  34  is formed on a peripheral region of the contents pumping hole  31  of the button body  30  so that a lower hole  44  is inserted to a lower part of the button  40  for limiting the button not to slide excessively. 
     The upper surface of the button  40  is shaped as the same concave surface as the upper surface of the button body  30  and the leg portions are formed on the lower surface of the button to be inserted, respectively into the sliding hole  32  of the button body  30 . 
     The leg portions includes a guide protrusion  42  which is guided along the sliding hole  32 , a leg  43  protruding downward on a rear end of the guide protrusion  42 , and a stumbling protrusion  41  to be hung over the side wall lower end of the sliding hole  31  at the distal end of the leg  43 . 
     A lower hole  44  protruding downward is formed on a center line in a sliding direction on a lower surface of the button  40  so that when the button  40  is slid forward totally, that is, the button is biased rearward, the lower hole corresponds to the contents pumping hole  31  of the button body  30 . Further, a front lower surface discharging hole  45  for discharging the contents is formed on a front side lower surface of the button  40  to be communicated with the lower hole  44 . 
     The shoulder  20  includes a screw connection portion to be screw-connected to the upper outer peripheral surface of the container  10  on its lower part, a cylindrical protrusion  23  protruding upward and having a smaller inner diameter than that of the screw connection portion  22 , an inner protrusion  24  protruding as a cylinder form and forming a groove  24   a  spaced at a predetermined distance from the inner peripheral surface of the cylinder protrusion  23 , and a stepped surface  25  at a lower level, forming a hollow space  25   a  on an inner peripheral surface of the inner protrusion  24  on a center. 
     Here, the leg  43  of the button  40  is placed on the stepped surface  25  when the button is locked, and when the button is slid forward, the leg  43  is placed on the hollow space  25   a  at a center of the stepped surface  25  for the button body  30  to be compressed. 
     With respect to an operation of the open and close apparatus of a button sliding type of a contents instrument according to the present invention as configured in the forgoing, firstly, when the button  40  is placed at a center of the container  10 , as shown in  FIG. 1 , the button body  30 , together with the button  40 , is not compressed, as shown in  FIG. 16 . In order to open the contents instrument for discharging the contents through the discharging hole  45 , firstly, an upper surface of the button is slid by using a finger, the guide protrusion  42  of the button  40  is moved forward within the sliding hole  32  of the button body  30  and the discharging hole  45  is protruded toward a front lower end. At this time, the lower hole  44  corresponds to the contents pumping hole  31  of the button body  30  and at the same time the leg  43  of the button  40  is placed on the hollow space  25   a  of the stepped surface  25  of the shoulder  20  at a center, thereby compressing the button body  30 .
