Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an automatic filling up spuit, and more particularly, to an automatic filling up spuit with a simple structure, which is capable of automatically filling up liquid contents in a cosmetics container by a certain amount precisely at all times through joining with the cosmetics container without requiring a complicated operation. 
         [0003]    2. Description of the Related Art 
         [0004]    In general, as one of methods of using liquid contents such as eye creams, cosmetics and the like desirable of use of the required small quantity at one time, there has been conventionally used a method of packing liquid contents individually in the form of a capsule or the like containing a desired quantity of liquid contents for each use. However, such an individual packing method has a problem of inefficiency since a relatively large quantity of contents is still left even when a user considers the contents to be used up. 
         [0005]    To overcome such a problem of the individual packing method, there has been devised a structure in which contents stored in a container are drawn out for each use by using a drawing means having a traditional spuit, syringe or push pump structure or the like. 
         [0006]    However, for the spuit-structured drawing means, since the amount of suction or drawing of the contents is varied depending on an amount by which a user presses a rubber pressing part, it may be impossible or nearly impossible to draw out the contents precisely by a certain quantity for each use. 
         [0007]    In addition, for the syringe-structured drawing means, considering that an extremely small quantity (for example, about 1 ml) of contents is mostly used, there is a configuration trouble in that the diameter of a syringe or a stroke of a syringe piston has to be made very small. Further, there is a demerit of very troublesome use since the syringe piston has to be pulled to suction the contents and then be pushed to draw out the contents. 
         [0008]    On the other hand, for the push pump-structured drawing means, although it has a merit that a certain amount of contents can be drawn out if only a button is simply pushed, there is a demerit of complicated structure in that it includes a button, a discharge port, a spring, a valve structure and so on as well as a structure forming the interior and exterior of the pump. In addition, it is common to use a suction tube to suction the contents on the characteristics of the push pump mainly installed in the upper portion of the container. However, in this case, there may be an impossibility of drawing-out of the contents left in the container depending on a position of the suction tube. 
       SUMMARY OF THE INVENTION 
       [0009]    Accordingly, it is an object of the present invention to provide an automatic filling up spuit with a simple structure, which is capable of automatically filling up liquid contents in a cosmetics container by a certain amount precisely at all times through joining with the cosmetics container without requiring a complicated operation. 
         [0010]    To achieve the above object, according to an aspect of the invention, there is provided an automatic filling up spuit ( 100 ) screwed to an entrance ( 1   a ) of a cosmetics container ( 1 ) for suctioning and discharging liquid stored in the cosmetics container ( 1 ), comprising a spuit pipe ( 10 ) serving as a passage for suction and discharge of liquid stored in the cosmetics container ( 1 ); a cylinder member ( 20 ) combined to the top inner circumference of the spuit pipe ( 10 ); a piston member ( 30 ) configured to fill the cylinder member ( 20 ) with cosmetics liquid via the spuit pipe ( 10 ) while ascending with rising of the cylinder member ( 20 ); a top/bottom-opened cylindrical piston guide member ( 40 ) which is inserted in the outer circumference of the piston member ( 30 ), with a vertical groove ( 41 ) formed on the inner circumference of the piston guide member ( 40 ) and inserted with a horizontal bar ( 34 ) of the piston member ( 30 ), for guiding the vertical movement of the piston member ( 30 ); a cylindrical push button ( 50 ) which discharges cosmetics solution filled in the cylinder ( 21 ) via the spuit pipe ( 10 ) while the piston member ( 30 ) is being descended by pushing the push button ( 50 ), with an insertion projection ( 51 ) formed on a bottom-opened ceiling and inserted in the outer circumference of a circular projection ( 35 ) projecting to the upper center of the horizontal plane ( 32 ) of the piston member ( 30 ); and a top/bottom-opened cylindrical enclosure ( 60 ) which encloses the outer circumference of the cylindrical push button ( 50 ) and the piston guide member ( 40 ).

         [0020]    As shown in  FIGS. 1 to 3 , an automatic filling up spuit  100  screwed to an entrance  1   a  of a cosmetics container  1  for suctioning and discharging liquid stored in the cosmetics container  1  includes a spuit pipe  10  serving as a passage for suction and discharge of liquid stored in the cosmetics container; a cylinder member  20  which includes an inner cylinder  21  combined to the top inner circumference of the spuit pipe  10 , a bottom-opened cylindrical portion  23  formed downward around a horizontal plane  22  formed on the middle outer circumference of the cylinder  21 , with an inclined groove  24  symmetrically formed on the outer circumference of the cylindrical portion  23 , and a screw combining portion  25  formed on the inner circumference of the cylindrical portion  23  and screwed to the entrance la of the cosmetics container  1 ; a piston member  30  which includes a bar-like piston  31  provided with a cylindrical packing  31   a  on the bottom outer circumference inserted from top in the inner circumference of the cylinder  21 , two vertical guides  33  projecting downward around a horizontal plane  32  formed on the top of the piston  31 , and a horizontal bar  34  projecting outward from the bottom of the vertical guides  33 ; a top/bottom-opened cylindrical piston guide member  40  which is inserted in the outer circumference of the piston member  30 , with a vertical groove  41  formed on the inner circumference of the piston guide member  40  and inserted with the horizontal bar  34  of the piston member  30 , for guiding the vertical movement of the piston member  30 ; a cylindrical push button  50  which discharges cosmetics solution filled in the cylinder  21  via the spuit pipe  10  while the piston member  30  is being descended by pushing the push button  50 , with an insertion projection  51  formed on a bottom-opened ceiling and inserted in the outer circumference of a circular projection  35  projecting to the upper center of the horizontal plane  32  of the piston member  30 ; and a top/bottom-opened cylindrical enclosure  60  which encloses the outer circumference of the cylindrical push button  50  and the piston guide member  40 . 
         [0021]    Next, operation and effects of the automatic filling up spuit as configured above will be described. 
         [0022]    An assembling procedure of the automatic filling up spuit  100  will be first described. First, the piston  31  assembled with the cylindrical packing  31   a  is inserted in the inner circumference of the cylinder  21 , and the cylindrical piston guide member  40  is assembled through the lower side of the outer circumference of the piston member  30  such that the horizontal bar  34  projecting to the bottom outer side of the vertical guides  33  of the piston member  30  is inserted in the vertical groove  41 . 
         [0023]    Next, the cylindrical enclosure  60  is inserted in and combined to the outer circumference of the piston guide member  40  from below. Thereafter, the insertion projection  51  is inserted in the outer circumference of the circular projection  35  of the piston member  30  and the spuit pipe  10  is assembled to the bottom of the cylinder  21  of the cylinder member  20  to complete the assembly of the automatic filling up spuit  100 . 
         [0024]    In the assembled automatic filling up spuit  100 , the screw combining portion  25  of the cylinder member  20  is screwed to the cosmetics container  1 . As shown in  FIG. 3 , with the outer circumference of the cylindrical enclosure  60  grasped by one hand of a user, when the screw combining portion  25  is screwed to the cosmetics container  1  storing the liquid and the container  1  continues to be turned in a screw combination direction, the horizontal bar  34  of the piston member  30  lying on the inclined groove  24  formed on the outer circumference of the cylindrical portion  23  is ascended along an inclined plane while the screwed cylinder member  20  continues to be rotated. When the horizontal bar  34  is ascended, the liquid in the cosmetics container  1  is filled in the inner space of the cylinder  21  through the spuit pipe  10  while the cylindrical packing  31   a  adhered to the inner circumference of the cylinder  21  is being ascended along the piston  31 . 
         [0025]    In this manner, with the cosmetics liquid filled in the inner space of the cylinder  21 , as shown in  FIG. 3 , for the purpose of using the cosmetics, the combined screw is released to separate the automatic filling up spuit  100  from the cosmetics container  1 . That is, when the push button  50  is little by little pushed by a thumb, with the cylindrical enclosure gasped by a palm, the liquid filled in the inner space of the cylinder  21  is discharged via the spuit pipe  10  while the piston member  30  combined to the bottom of the push button  50  is being descended.
