Patent Abstract:
A pump-type cosmetics container is not subject to the risk of a foreign substance entering into a nozzle, due to a moving path through which content is discharged during use that is selectively open by means of an opening/closing bracket, and to the risk of change in quality of the content inside the moving path, by means of a counteraction of a control protrusion pressing a locking protrusion thereby re-aspirating the content remaining inside the moving path, after pumping using a double spring.

Full Description:
BACKGROUND 
       [0001]    The present invention relates to a pump-type cosmetics container, and in particular to a pump-type cosmetics container which makes it possible to prevent a foreign substance from entering into a nozzle in such a way that a moving passage through which contents discharge when in use can be selectively open by means of an opening and closing bracket. 
         [0002]    A cosmetics container designed to store liquid or gel state cosmetics is equipped with a vacuum pump which is configured to externally discharge an accurate amount of contents which are stored at an injection port. 
         [0003]    The above mentioned vacuum pump is manufactured in various structures. According to such vacuum pump, when an operation button installed at the top of a nozzle cap serving to open and close the injection port of the cosmetics container is pressed, vacuum pressure is formed in the interior through a pumping operation, and a certain amount of the contents stored in the container is discharged to the outside through the nozzle by means of the vacuum pressure. 
         [0004]    The conventional cosmetics container, in general, is equipped with a vacuum pump, but the storing container is formed in a single structure, so it is hard to maintain a vacuum state in the storing container. For this reason, external air may be inputted into the container or light may transmit through the container, so pumping efficiency becomes bad, and the contents stored in the container may be contaminated or spoiled, the problems of which are based on structural problems. 
         [0005]    In order to improve the above listed problems, there is provided a double cosmetics container which has features in that a cosmetic container equipped with a vacuum pump at an injection port of a storing container is made in a double structure consisting of an inner container and an outer container. 
         [0006]    As shown in  FIG. 5 , the conventional cosmetics container configured in a double structure equipped with a vacuum pump is formed of a cosmetic container of a double structure consisting of an inner container  10  storing contents and an outer container  20  which protects the inner container while serving to make the exterior look good. 
         [0007]    The vacuum pump  30  has features in that an operation cylinder  31  and a nozzle cap  32  are installed at the injection port of the inner container  10  and at the inner and outer sides in an overlapping structure. At the nozzle cap  32  is disposed an operation button  34  with a nozzle  33  in such a way that the operation button  34  can ascend and descend. 
         [0008]    A piston  35  is vertically connected to the bottom of the nozzle cap  32  and ascends and descends in an operation cylinder  31 . A piston rest tube  36  is so installed that an orifice can be formed at an inner diameter portion of the piston  35 . A valve  37  is provided at an outer surface of the bottom, so the piston can ascend and descend in the operation cylinder  31  for thereby closing and opening a fluid passage. The operation button  34  is elastically installed by means of a return spring  38 . 
         [0009]    A fluid passage communicating with the inner container  10  is provided in the operation cylinder  31 . An opening and closing valve  39  is installed at the fluid passage. The fluid passage can be opened and closed thanks to the vacuum pressure formed through the pumping operation. 
         [0010]    According to the thusly configured double cosmetics container, when the operation button  34  is pressed, the return spring  38  is compressed and descends, and the piston  35  and the valve  37  and the piston rest tube  36  all descend by means of the pressing pressure for thereby compressing the space of the operation cylinder  31 . 
         [0011]    The vacuum pressure of the operation cylinder  31  increases, and the portion between the valve  37  and the piston rest tube  36  opens, and the contents in the operation cylinder  31  is discharged to the outside through the opened gap and through the orifice of the piston rest tube  36  and through the nozzle  33  of the operation button  34 . 
         [0012]    At this time, the opening and closing valve  39  maintains the fluid passage closed with the aid of the pressure of the operation cylinder  31 . On the contrary, when the pressed operation button  34  is released, the piston  35 , the valve  37  and the piston rest tube  36  ascend to their original positions by means of the recovering force of the return spring  38 . For this operations, a vacuum pressure is formed in the operation cylinder  31 , and the opening and closing valve  39  allows the fluid passage to open, so the contents in the inner container  10  flows in the operation cylinder  31  and standbys for the next discharge. 
         [0013]    The above described conventional cosmetics container, however, has problems in that since the nozzle always remains exposed, the contents remaining in the interior of the nozzle may be spoiled, which results in a sanitary problem. In addition, the contents may be discharged by means of a pumping by mistakes, so the contents may be consumed unintentionally.

         [0033]    The top of the container body  10  is sealed by means of a cover  110 , and at the top of the cove  110  are formed a first space  111 , a second space  112  and a third space  113 . 
         [0034]    The first space  111  is a space in which the pumping member  200  is installed for thereby pumping out the contents stored in the container body  100 , and the second space  112  is a space which supports the bottom of the lower spring S1 and seals the pumping member  200  to which is inserted a sealing bracket  700 . 
         [0035]    The third space  113  is a space surrounding the exterior of the operation space  320  for thereby accommodating the operation space of the locking member  300 . 
         [0036]    The pumping member  200  is installed in the first space  111  and sucks the contents of the container body  100  and moves them to the moving passage  410  of the intermediate member  400 . As shown in  FIGS. 1 to 4 , the pumping member  200  comprises a suction part  210 , a suction nozzle  220  and a piston  230 . 
         [0037]    The suction part  210  is installed at the bottom of the first space  111  and sucks the contents through the pumping operations of the suction nozzle  220  and the piston  230 . The thusly sucked contents move through the suction nozzle  220  and through the communicating hole  710  and the hollow part  310  and to the moving passage  410 . 
         [0038]    The communicating hole  710  is a kind of through hole passing through the sealing bracket  700  from top to bottom, and the sealing bracket  700  seals the exterior of the pumping member  200 , the bottom of which sealing bracket  700  being inserted into the second space  112 . 
         [0039]    As shown in  FIGS. 1 to 4 , the locking member  300  is engaged to the top of the container body  100 . The locking member  300  comprises a hollow part  310 , an operation space  320  and a locking protrusion  330 . 
         [0040]    The hollow part  310  is formed in the center of the locking member  300  and passes through the same from top to bottom, and the hollow part  310  communicates with the communicating hole  710  and the moving passage  410 . 
         [0041]    On the top of the locking member  300  is formed an operation space  320  in the upward and downward directions. The operation space  320  is a space into which an external operation bracket  440  is inserted and operates, and is accommodated in the third space  113 . 
         [0042]    At the top of the licking member  300  is provided a locking protrusion  330  which is equipped with the sunk part  331 . The locking protrusion  330  allows the control protrusion  520  to be fixedly inserted into the sunk part  331  when the opening and closing bracket  500  is sealing the end portion of the moving passage  410 , and when the moving passage  410  is opened, the opening and closing bracket  500  is tilted upward, and the locking protrusion  330  separates from the sunk part  331 . 
         [0043]    As shown in  FIGS. 1 to 4 , the intermediate member  400  is engaged to the top of the locking member  300  and is equipped with a passing passage  410  communicating with the hollow part  310  and the communicating hole  710 . The contents pumped out by the pumping member  200  are inputted into the moving passage  410  and are discharged from the end portion. 
         [0044]    As shown in  FIGS. 2 to 4 , on the top of the intermediate member  400  is provided a rotation space  420  and a rotation groove  430 . At the inner surface of the intermediate member  400  is formed an internal operation bracket  450 . Into the rotation space  420  is inserted the rotary shaft of the opening and closing bracket  500  thereby allowing the opening and closing bracket  500  to rotate. 
         [0045]    In the rotation groove  430  is rotatable a control protrusion  520  which is connected to the rotary shaft  510  in a row. The rotation groove  430  and the rotation space  420  are formed continuously. 
         [0046]    The internal operation bracket  450  passes through the hollow part  310  and is inserted into the communicating hole  710  and moves upward and downward. The internal operation bracket  450  can prevent contents from leaking into the hollow part  310 . 
         [0047]    As shown in  FIGS. 1 to 4 , the opening and closing bracket  500  comprises a rotary shaft  510 , a control protrusion  520  and an opening and closing part  530 . The opening and closing bracket  500  selectively opens and closes the end portion of the moving passage  410 . 
         [0048]    The rotary shaft  510  is inserted into the rotation space  420  and is rotatable therein. The control protrusion  520  is continuous from the rotary shaft  510 . An end portion of the control protrusion  520  is fixedly inserted into the sunk part  331  of the locking protrusion  330  at a portion where the opening and closing bracket  500  is blocking the end portion of the moving passage  410 . When the rotary shaft  5100  rotates, the end portion of the moving passage  410  is opened and tilted 
         [0049]    Here, the opening and closing part  530  is formed in a shape to cover the end portion of the moving passage  410 . When the opening and closing bracket  500  rotates by the rotary shaft  510 , the moving passage  410  is selectively opened or closed for thereby blocking foreign substances from entering into the moving passage  410 . 
         [0050]    It is preferred that on the top of the intermediate part  400  is provided a button  600 . As shown in  FIG. 3 , the button  600  comes to operates in the upward and downward directions after the fixed control protrusion  520  is released from the locking protrusion  330  when the opening and closing bracket  500  rotates and is tilted. 
         [0051]    When the user presses the button  600  down, the contents stored in the container body  100  can be discharged. 
         [0052]    A protrusion part  610  is formed on an outer surface of the button  600 . The protrusion  610  covers the top of the end portion of the moving passage  410 . 
         [0053]    The button  600  prevents the intermediate portion  400  from being exposed to the outside, for thereby making it look good. 
         [0054]    The operations of the pump-type cosmetics container according to the present invention will be described. 
         [0055]      FIG. 2  is a view illustrating an initial state of the pump-type cosmetics container according to a preferred embodiment of the present invention. 
         [0056]    In the above mentioned initial state, the user rotates the opening and closing bracket  500  and opens the end portion of the moving passage and at the same time separates the control protrusion  520  from the sunk part  331 , so the initial state changes into the state of  FIG. 3 . 
         [0057]    In a state that the end portion of the moving passage  410  is open, the user pressurizes the button  600  downward, and the intermediate member  400  moves downward until the lower end portion of the internal operation bracket  450  reaches the engaging shoulder  711  provided in the interior of the communicating hole  710 , the operations of which are called a first downward movement stage. In this state, since the pumping member  200  does not operate, elastic recovery force is not stored in the lower spring S1 and the upper spring S2. 
         [0058]    In the first downward movement stage, when the user continues to press the button  600 , as shown in Figure, the intermediate part  40  moves downward, and at the same time the internal operation bracket  450  moves downward along the inner wall of the communicating hole  710 , and the external operation bracket  440  is inserted into the operation space  320  and moves downward. 
         [0059]    Here, since the end portion of the internal operation bracket  450  is contacting with the engaging shoulder  711  provided in the interior of the communicating hole  710 , the sealing bracket  700  moves downward by means of the press of the button  600 , the operations of which are called a second downward movement stage. 
         [0060]    When the sealing bracket  700  moves downward, elastic recovery force is stored in the lower spring S1 the lower end portion of which is supported, and at the same time the lower end portion is supported by the top of the sealing bracket  700 , and elastic recovery force is stored in the upper spring S2 the upper end portion of which is supported by the inner wall of the intermediate member  400 . 
         [0061]    In addition, as the elastic force is stored in both the lower spring S1 and the upper spring S2, when the sealing bracket  700  moves downward, the pumping member  200  moves downward, and the contents stored in the container body  100  can be pumped out. 
         [0062]    The contents pumped out by the pumping member  200  is discharged to the outside through the moving passage  410 . 
         [0063]    After the contents are pumped out by pressing the button  600  down, the intermediate member  400  and the sealing bracket  700  move back downward, and the intermediate member  400  and the sealing bracket  700  ascend up to the same position as the first downward movement stage. 
         [0064]    Thereafter, the user rotates the tilted opening and closing bracket  500  and seals the end portion of the moving passage  410  with the aid of the opening and closing part  530 . In order for the opening bracket  500  to close the end portion of the moving passage  410 , the opening and closing bracket  500  is rotated in the direction opposite to the direction that the end portion of the moving passage  410  is opened. 
         [0065]    After this, the control protrusion  520  presses the locking protrusion  330 , and the end portion is inserted into the sunk part  331 . As a counteraction with respect to the action that the locking protrusion  330  is pressed, the intermediate member  400  moves upward, and the inner pressure is formed in the interior of the communicating hole  710 , and the contents remaining in the moving passage  410  is sucked back into the interior of the communicating hole  710 . 
         [0066]    When the end portion of the control protrusion  520  is inserted into the sunk part  331 , the opening and closing part  530  comes to close the end portion of the moving passage  410  and at the same time prevents the intermediate member  400  from moving downward. The pump-type cosmetics container according to a preferred embodiment of the present invention remains in a locked state until the user tilts again the opening and closing bracket  500 . 
         [0067]    As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, 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 spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
