Therefore, a user can use the container while adjusting discharged amount to a desired amount.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention disclosed herein relates to a cream type cosmetic container. The container is configured in such a manner that when a user presses an elastic button, the elastic button moves downwards and is restored due to elasticity of the elastic button per se, and contents are discharged by changing the pressure of the inside of a container body, whereby it is possible to readily discharge contents having high viscosity through a simple structure even if a separate pumping member does not exist, and thus, not only an assembly time but also a manufacturing cost can be reduced. 
         [0002]    Generally, cream-type cosmetic containers storing highly viscous cream are configured to interrupt a contact between air and contents contained in the cosmetic containers. Such an exemplary vacuum-type cosmetic container as above is disclosed in Korean Utility Model No. 20-0311503 filed and owned by the present applicant. 
         [0003]    This utility model discloses a dispenser container including a container part ( 10 ) storing contents, and a dispenser ( 100 ) coupled to an upper end of the container part ( 10 ), wherein the dispenser ( 100 ) includes a cylinder ( 20 ) having an intake hole ( 22 ) and coupled to the upper end of the container part ( 10 ), a valve body ( 30 ) disposed at an intake hole ( 22 ) of the cylinder ( 20 ), a button ( 40 ) disposed at the cylinder ( 20 ) so as to perform repetitive pumping and including a tray part ( 42 ) extended so as to cover an upper part of the container part ( 10 ) at an upper end thereof, and a piston ( 50 ) disposed between an inner wall surface of the cylinder ( 20 ) and a lower end portion of the button ( 40 ). Here, the button ( 40 ) has a slide hole ( 44 ) formed at a central portion thereof in a vertical direction, and the valve body ( 30 ) has an upper end thereof upwardly extending and slidably inserted into the slide hole ( 44 ) of the button. Also, a cover member ( 60 ) is coupled to the upper end of the valve body ( 30 ) to cover the slide hole ( 44 ) of the button ( 40 ). Thus, when the button ( 40 ) is pushed, the button ( 40 ) descends along an outer circumferential surface of the valve body ( 30 ), generating a gap between the cover member ( 60 ) and the button ( 40 ), and thereby contents are discharged through the gap and collected in the tray part ( 42 ) of the button ( 40 ). 
         [0004]    However, in this utility model, the dispenser ( 100 ) including the cylinder ( 20 ) with the intake hole ( 22 ) at the lower end thereof is coupled to an upper portion of the container part ( 10 ) to discharge contents stored in the container part ( 10 ). Accordingly, since this utility model has a structure in which pumping is performed through the dispenser ( 100 ) having a complicated structure, there is a limitation wherein an assembling time for installing the dispenser ( 100 ) increases and so does a manufacturing cost. 
       SUMMARY OF THE INVENTION 
       [0005]    The present invention is devised to solve the said problems above, and its goal is to provide a cream-type cosmetic container, which can easily discharge a highly viscous contents without a separate pumping member by allowing a button part to move downwards and then return to an original location and thus changing the internal pressure of the container body when a user pressurizes the button part, and thus can save an assembling time and reduce a manufacturing cost thereof. 
         [0006]    Furthermore, the present invention also provides a cream-type cosmetic container, wherein by coupling a valve member made of elastic material at a bottom surface, when an elastic button descends, the valve member closes a content inflow hole and the contents stored in a content suctioning part is discharged to a content discharging hole; meanwhile, when the elastic button ascends, the valve member opens the content inflow hole and the contents stored in the container body flow into the content suctioning part with a constant amount. Therefore, the present invention is able to discharge a constant amount contents by means of a simple structure above. 
         [0007]    The present invention is devised to solve such problems described in the above, and a cream-type cosmetic container comprises a container body receiving contents and having a volume thereof reduced according to using contents; a pumping guide cap coupled to an upper portion of the container body and having elastic deformation according to the presence/absence of a user&#39;s pressurization, thereby discharging contents contained in the container body by a pumping operation; and a content suctioning part coupled at an inner side of the container body and forming a space in which contents is stored at a lower portion of the pumping guide cap, further comprising a content inflow hole such that contents stored in the container body can move in by the constant amount. 
         [0008]    To solve the above problems, it is featured that at a side of an upper portion of the pumping guide member is provided an elastic button made of elastic material which moves downwards and induce a pumping operation by changing the pressure of a space formed by the pumping guide cap and the content suctioning part, wherein at a bottom surface of the elastic button is provided a first valve member which opens/closes the content inflow hole. 
         [0009]    Furthermore, it is featured that the first valve member is made of elastic material deformed when contacting an upper portion of the content suctioning part, such that the first valve member may not be interrupted by the top of the content suctioning part when the elastic button is lowered. 
         [0010]    Furthermore, it is featured that the first valve member is molded as an integral by double injection at a bottom surface of the elastic button. 
         [0011]    Furthermore, it is featured that the pumping guide cap further comprises a coupling part which is coupled to an upper portion of the container body and couples the pumping guide cap to the container body, and a content discharging hole which is disposed at the other side of the upper portion of the pumping guide cap and discharges contents by manipulating the elastic button. 
         [0012]    Furthermore, it is featured that at the pumping guide cap is provided a second valve member which opens/closes the content discharging hole according to the presence or absence of pressurization. 
         [0013]    As described above, according to the present invention, when a user presses an elastic button, the elastic button moves downwards and is restored due to elasticity of the elastic button per se, thereby changing the inside pressure of the container and discharging contents. Therefore, highly viscous contents can easily be discharged without a separate pumping member and thus not only an assembling time but also a manufacturing cost thereof is reduced. 
         [0014]    Furthermore, since a bottom surface of the elastic button is coupled with a valve member of elastic material, when the elastic button is lowered, the valve member closes a content inflow hole and allows contents stored in the content suctioning part to a content discharging hole. Meanwhile, when the elastic button is ascended, the valve member opens the content inflow hole and leads contents stored in the container body to the content suctioning part through the content inflow hole. Therefore, the present invention has advantages in that a constant amount of contents are always discharged by means of a simple structure therein.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0019]    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members. 
         [0020]      FIG. 1  is an exploded perspective view illustrating a configuration of a cream-type cosmetic container according to an exemplary embodiment of the present invention.  FIG. 2  is an assembled perspective view illustrating a configuration of a cream-type cosmetic container according to an exemplary embodiment of the present invention.  FIG. 3  is an assembled cross-sectional view illustrating a configuration of a cream-type cosmetic container according to an exemplary embodiment of the present invention. 
         [0021]    Referring to  FIGS. 1 to 3 , a cream-type cosmetic container according to an exemplary embodiment of the present invention may include a container body  100 , a pumping guide cap  200 , a content suctioning part  300 , and a closing cap  400 . 
         [0022]    The container body  100  receives contents and has a volume thereof reduced according to using contents. More simply saying, it is possible to install a piston  110  therein which ascends according to using contents, and also possible separately to install an inner container therein which is made of soft material and can be absorbed according to using contents. 
         [0023]    Meanwhile, an air inflow hole  120 , which will be described later, is formed at a lower end portion of the container body  100  such that air can flow into the container body  100  when the piston  110  is ascended by a pumping operation through manipulating a pumping guide cap  200 . 
         [0024]    The pumping guide cap  200  coupled to an upper portion of the container body  100  to close an upper-end opening of the container body  100  comprises a coupling part  210  coupled to an upper portion of the container body  100  so as to fix the pumping guide cap  200  to the upper portion of the container body  100 . 
         [0025]    In the present invention, at one side of the upper end of the pumping guide cap  200  is provided an elastic button  220  which is elastically deformed according to a user&#39;s pressurizing and changes the pressure of a space formed by the content suctioning part  300  which will be described later and the pumping guide cap  200 , thereby discharging contents suctioned into the content suctioning part  300  to the outside. The elastic button  220  protrudes from the pumping guide cap  200  to an upward direction, and the entire surface thereof, when a user pressurizes an upper end of the elastic button  220 , moves to a downward direction and then is restored when the user depressurizes, thereby changing the pressure of a space formed by the content suctioning part  300  and the pumping guide cap  200  and guiding a pumping operation. The elastic button  220  is made of elastic material so as to be deformed according to the presence or absence of a user&#39;s pressurizing. 
         [0026]    In the present invention, at a bottom surface of the elastic button  220  is provided a first valve member  221  which opens/closes a content inflow hole  310  of the content suctioning part  300  according to the presence or absence of a user&#39;s pressurizing, wherein the first valve member  221 , when the elastic button  220  descends, closes the content inflow hole  310 , such that contents stored in the content suctioning part  300  can be discharged to a content discharging hole  230 . Meanwhile, the first valve member  221 , when the elastic button  220  ascends, opens the content inflow hole  310 , such that contents stored in the container body  100  flows into the content suctioning part  300  through the content inflow hole  310  by a predetermined amount of contents. 
         [0027]    The first valve member  221  is contacted to an upper end of the content suctioning part  300  in a process that the elastic button  220  descends and closes the content inflow hole  310 ; therefore, it is preferred that the first valve member  221  should be made of elastic material which can be deformed upon contacting an upper end of the content suctioning part  300  such that the elastic button  220  may not be interrupted while descending. 
         [0028]    Furthermore, it is possible that the first valve member  221  can be fitted with a bottom surface, but it is preferable to be molded as an integral through a double injection. 
         [0029]    Meanwhile, at the other side of the upper end of the pumping guide cap  200  is provided a content discharging hole  230  such that contents can be discharged by a pumping operation according to the manipulation of the button part  220 , wherein the pumping guide cap  200  includes a second valve member  231  which opens/closes the content discharging hole  230  according to whether or not the button part  220  is pressurized. 
         [0030]    The content suctioning part  300  is coupled to a lower portion of the pumping guide cap  200  inside the container body  100 , and suctions a fixed amount of contents stored in the container body  100  due to an elastic deformation of the button part  220  of the pumping guide cap  200 , forming a space for storing contents and coupled at a lower portion of the pumping guide cap  200  with a fixed distance apart such that the contents stored in the container body  100  can be absorbed and flow in the space therein. 
         [0031]    Furthermore, a content inflow hole  310  is equipped at the content suctioning part  300  such that contents stored in the container body  100  may flow in, wherein the content inflow hole  310  is preferred to be disposed at directly below a first valve member  221  so as to be opened/closed by the first valve member  221  equipped at the bottom surface of the elastic button  220  according to whether the elastic button  220  is pressurized or not. 
         [0032]    The content suctioning part  300  may suction and store a uniform amount of contents contained in the container body  100 , and may be guided so as to discharge a uniform amount of contents upon pumping operation according to the manipulation of the button part  220 . 
         [0033]    The closing cap  400  coupled to an upper portion of the container body  100  while covering the pumping guide cap  200  prevents a malfunction of the button part  220 , and also prevents the first valve member  221  from being destroyed by an external impact. 
         [0034]    At an upper end of the closing cap  400  is formed a pressurizing protrusion  410  pressurizing an upper end of the pumping guide cap  200  such that the pumping guide cap  200  can be prevented from being separated from the container body  100 . 
         [0035]    Hereinafter, referring  FIG. 4 , an operational state of a cream-type cosmetic container according to an exemplary embodiment of the present invention will be described.  FIG. 4  is a view illustrating an operational state of a cream-type cosmetic container according to an exemplary embodiment of the present invention. 
         [0036]    Referring  FIG. 4 , in a cream-type cosmetic container according to an exemplary embodiment of the present invention, when a user pressurizes an elastic button  220  formed at a side of the pumping guide cap  200 , the elastic button  220  made of elastic material moves downwards, and thereby moves along with a first valve member  221  equipped at a bottom surface of the elastic button  220 , thus closing a content inflow hole  310 . 
         [0037]    In a process of the elastic button  220 &#39;s descending as the above, when the first valve member  221  closes the content inflow hole  310 , the contents stored in a space formed by the pumping guide cap  200  and the content suctioning part  300  move to a direction of content discharging hole  230  formed at the other side of the pumping guide cap  200 , and the first valve member  221  closed by the content discharging hole  230  opens the content discharging hole  230  by the content pressure, thereby discharging the contents absorbed into the content suctioning part  300  to an top surface of the pumping guide cap  200 . 
         [0038]    Meanwhile, when a user releases a pressurization of an elastic button  220 , the elastic button  220  is restored by an inherent elasticity of the elastic button  220  and moves upwards, and thereby a first valve member  221  equipped at a bottom surface of the elastic button  220  ascends along and opens the content inflow hole  310 . 
         [0039]    In a process of the elastic button  220 &#39;s ascending as the above, when the first valve member  221  opens the content inflow hole  310 , a fixed amount of the contents stored in a space formed by the pumping guide cap  200  and the content suctioning part  300 , which can be discharged during the next pumping operation, move into the content suctioning part  300  through the content inflow hole  310 . At this time, a second valve member  231  closes the content discharging hole  230 .
