Description
    BACKGROUND
  • [0001]
    The present invention relates to a pumping-type cosmetic container, and in particular to a pumping-type cosmetic container which makes it possible to prevent air from entering into the interior of a wrinkled tube because sealing effects can be obtained without using a check valve in such a way that an elastic discharge part opened and closed by the pressure of contents is provided at the top of a pumping member, and a sealing shaft is engaged to the elastic discharge part.
  • [0002]
    A typical pumping-type cosmetic container configured to discharge contents with the aid of a pumping member comprises a container body which stores contents, a pumping member which is engaged to the top of the container body and performs a pumping operation, and a button member which is positioned at the top of the pumping member and enables a pumping operation as a user pressurizes, and a button member which has a discharge hole through which to discharge contents.
  • [0003]
    The above mentioned typical pumping-type cosmetic container has features in that when a user pressurizes the button member, the pumping member positioned below becomes activated for thereby discharging contents stored in the container body through a discharge hole; however the pumping member has complicated constructions, and the manufacture costs a lot, and it is time-consuming.
  • [0004]
    Since the pumping member activates a pumping operation with the aid of a metallic spring, the metallic spring may corrode, which spoils the contents.
  • [0005]
    In order to improve the above mentioned problems, there is developed “a pumping device for a cosmetic container” whose Korean registered patent number is 10-0545007.
  • [0006]
    In the above mentioned Korean registered patent, the pumping device for discharging part of the fluid stored in the interior of the container comprises a pumping head 10 which is provided at the top of a head housing 20 while sealing it and ascends and descends along the inner surface of a head accommodation rib 22 for thereby depressurizing and pressurizing the fluid in the interior, the bottom of the pumping head 10 being open, and is equipped with a nozzle 11 through which to discharge the fluid of the interior to the outside and a discharge tube 12 which stands downward in the inner center for the purpose of supplying the fluid to the nozzle; a head housing 20 which covers the top of the container while sealing the same and air-tightly seal the open bottom of the pumping head 10 and is equipped with a bottom valve hole 21 at the center of which a bottom valve 60 is disposed, a head accommodation rib 22 being upright so as to air-tightly guide the bottom of the pumping head 10 which ascends and descends along an upper outer surface, a wrinkled tube accommodation rib 23 air-tightly sealing the bottom of the wrinkled tube 30 at the center of the upper surface being upwardly protruding from the outer side of the bottom valve hole 21, an engaging member 24 at an outer lower side being air-tightly engaged to the top of the container 70; an elastic wrinkled tube 30 which is contracted when the pumping head 10 descends and ascends the pumping head 10 by means of an elastic force when a descending pressure is removed, the top of which being air-tightly engaged to the bottom of the discharge tube 12 of the pumping head 10, the bottom of which being engaged air-tightly sealing the head housing including the bottom valve hole 21 of the head housing 30; a top valve housing 40 which air-tightly seal the end of the lower side of the discharge tube 12 of the pumping head 10, a top valve hole 41 passing through its center and to which the top valve 50 is engaged; a top valve 50 which is configured to open and close the top valve hole 41 of the top valve housing 40 and opens when the pressure of the interior of the wrinkled tube is higher than the pressure of the interior of the discharge tube 12 of the pumping head 10 and closes when the pressure of the interior of the discharge tube 12 is higher than the pressure of the interior of the wrinkled tube 30; and a bottom valve 60 which is configured to open and close the bottom valve hole 21 of the bottom valve housing 20 and opens when the pressure of the interior of the container 70 is higher than the pressure of the interior of the wrinkled tube 30 and closes when the pressure of the interior of the wrinkled tube 30 is higher than the pressure of the interior of the container 70.
  • [0007]
    According to the above described registered patent, the pumping operation is obtained using the winkled tube 30 made from a rubber material instead of a metallic spring used in the conventional art. Since the metallic spring is not used, it is possible to prevent the contents from being spoiled when occurs thanks to the corrosion of the metallic spring.
  • [0008]
    According to the above described registered patent, the top valve housing 40 equipped with the top valve hole 1 discharging the contents is engaged to the pumping head 10, so the top valve 50 opening and closing the top valve hole 41 should be provided. In addition, since the pumping structure is formed of the wrinkled tube 30 and the top valve housing 40, it needs to assemble all the above mentioned elements, which makes the assembling line took complicated, and since more parts are required, the manufacture costs a lot.
  • [0009]
    Since the weight 53 is required so as to pressurize the top valve 50 in the downward direction for the purpose of sealing the inner side of the wrinkled tube 30, the structure of the top valve 50 becomes complicated. Since the valve body 51 comes into contact with the upper surface of the top valve housing 40, deformation occurs at the end of the valve body 51, which causes a gap to form between an upper surface of the top valve housing 40 and the bottom of the valve body 51, so air may enter into the interior of the wrinkled tube 30, which consequently spoils the contents.
  • [0010]
    In addition, the granular contents may be solidified between the gaps formed in the check valve owing to the structure of the bottom valve 60, so erroneous operations may occur in the bottom valve 60.

    In the present invention, the pumping member 400 is equipped with an elastic discharge part 440 which inwardly extends and is configured to widen with the pressure of the contents for thereby discharging contents. The elastic discharge part 400 widens with the pressure of the contents and seals the outer surface of the sealing shaft 500 when the discharge of the contents is finished and prevents the air from entering into the interior of the wrinkled tube 42 and the contents from entering back. For this, the present invention can obtain a sealing effect on the interior of the wrinkled tube 420 without using the check valve.
  • [0048]
    The sealing shaft 500 is engaged to the top of the pumping member 400 for thereby closing the elastic discharge part 440 and comprises a body 510 which covers the top of the pumping member 400 and has a content discharge hole 511, and a closing rod 520 which protrudes from the top of the inner top of the body 510 in the downward direction and is engaged to the elastic discharge part 440.
  • [0049]
    The sealing shaft 500 can seal the interior of the wrinkled tube 420 with the aid of the closing rod 520 engaged to the elastic discharge part 440. When the elastic discharge part 440 is opened with the pressure of the contents, the contents can be discharged through the content discharge hole 511 formed in the body 510.
  • [0050]
    The button member 600 is engaged covering the pumping member 400 and is configured to discharge the contents through the pumping operations of the pumping member 400 and has a content discharge hole 610 communicating with the content discharge hole 511 for thereby discharging out the contents.
