     TECHNICAL FIELD 
       [0002]    Exemplary embodiments of the present invention relates to a container for cream-type cosmetics, and more particularly, to a container for cream-type cosmetics, which is configured to allow a button part to, when a user presses the button part, move downward by an elastic force of the button part itself and then return to the original position thereof while changing the pressure inside a body of the container to discharge contents therefrom, so that the container is able to easily discharge contents having high viscosity through a simple structure thereof without a separate pumping member, and thereby is able to reduce manufacturing costs as well as to shorten the assembling time period. 
       BACKGROUND 
       [0003]    Generally, a cream-type cosmetic container storing high viscosity cream therein is configured to prevent contents held in the cosmetic container from coming into contact with the air. Such a vacuum-type cosmetic container was disclosed in Korean U.M. Registration No. 20-0311503, which was previously filed by the same applicant as the invention and then was registered. 
         [0004]    The container in accordance with the cited document includes a container part  10  storing contents therein, and a dispenser  100  coupled to an upper end of the container part. The dispenser  100  includes a cylinder  20  that has on a lower end thereof a suction hole  22  and is coupled to the upper end of the container part  10 , a valve body  30  that is provided in the suction hole  22  of the cylinder  20 , a button  40  that has on an upper end thereof a plate part  42  enlarged to cover a top of the container part  10  and is provided in the cylinder  20  to facilitate repetitive pumping operations, and a piston  50  that is provided between an inner wall of the cylinder  20  and a lower end of the button  40 . Here, a slide hole  44  is vertically formed in a central portion of the button  40 , an upper end of the valve body  30  extends upwards to be slidably inserted into the slide hole  44  of the button  40 , and 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, if the button  40  is pressed down, the button  40  moves downward along an outer circumference of the valve body  30 , so that a gap is created between the cover member  60  and the button  40 , and contents are discharged through the gap to be collected on the plate part  42  of the button  40 . 
         [0005]    However, the container in accordance with the cited document configured as described above is problematic in that the dispenser  100  including the cylinder  20  that has on the lower end thereof the suction hole  22  is coupled to an upper portion of the container part  10  to discharge contents out from the container part  10 , so that a pumping operation is performed through the dispenser  100  of a complicated structure, and thereby an assembling time period for installing the dispenser  100  is increased, and in addition, manufacturing costs are inevitably increased.

     DETAILED DESCRIPTION 
       [0032]    Hereinafter, the present invention will be described in detail with reference to accompanying drawings. The same reference numerals denote the same elements throughout different drawings. 
         [0033]      FIG. 1  is an exploded sectional view showing a configuration of a container for cream-type cosmetics in accordance with a first embodiment of the present invention, and  FIG. 2  is an assembled sectional view showing the configuration of the container for the cream-type cosmetics in accordance with the first embodiment of the present invention. 
         [0034]    Referring to  FIGS. 1 and 2 , the container for cream-type cosmetics in accordance with the first embodiment of the present invention includes a container body  100 , a pumping guide cap  200 , and a closing cap  300 . 
         [0035]    The container body  100  accommodates contents therein, with a piston  110  provided in the container body to move upward as the contents are used. 
         [0036]    In the present invention, a valve member  140  is installed at an inner lower end of the container body  100  to control the flow of air and thereby prevent the piston  110  from moving downward by internal pressure of the container body  100 , which is generated during a pumping operation through an operation of the pumping guide cap  200  that will be described below. To this end, a valve support  120  is provided on the inner lower end of the container body  100 , and protrudes upward from a bottom surface of the container body  100  to support the valve member  140 . 
         [0037]    An air inlet hole  121  is formed in a central portion of the valve support  120  to be opened or closed by the valve member  140 . An air flow hole  130  is formed in the inner lower end of the container body  100  to allow air to flow into the container body  100  when the valve member  140  opens the air inlet hole  121 . 
         [0038]    The pumping guide cap  200  is coupled to an upper portion of the container body  100  to close an opening formed in an upper end of the container body  100 , and is provided with a coupling part  210  that is coupled to the upper portion of the container body  100  to allow the pumping guide cap  200  to be secured to the upper portion of the container body  100 . 
         [0039]    In the present invention, the pumping guide cap  200  is provided with a button part  220  that is elastically deformed as a user presses it and changes pressure in the container body  100  to discharge the contents out from the container body  100 . The button part  220  is operated such that an entire upper surface thereof moves downward if a user presses an upper end thereof, and the button part returns to an original position thereof if he or she releases the button part. The button part guides the pumping operation by changing pressure in the container body  100 , and is made of an elastic material to be elastically deformable depending on a user presses the button part. 
         [0040]    A contents discharge hole  221  is formed in a central portion of the button part  220  to discharge the contents in response to a pumping operation. The upper end of the button part  220  is more deeply recessed towards the central portion at which the contents discharge hole  221  is formed, so that it is possible to discharge the contents to the upper end of the button part  220  and to use the contents. 
         [0041]    The closing cap  300  is coupled to the upper portion of the container body  100  while surrounding the pumping guide cap  200 . The closing cap prevents the malfunction of the button part  220 , prevents foreign matter from falling onto the upper end of the button part  220 , and prevents a rubber tip R from being damaged by external impact. 
         [0042]    Meanwhile, a pressing protrusion  310  is formed on an upper end in the closing cap  300  to press the upper end of the pumping guide cap  200  and thereby prevent the pumping guide cap  200  from being separated from the container body  100 . 
         [0043]    Hereinafter, an operational state of the container for cream-type cosmetics in accordance with the first embodiment of the present invention will be described with reference to  FIG. 3 . 
         [0044]      FIG. 3  is a view showing the operational state of the container for the cream-type cosmetics in accordance with the first embodiment of the present invention. Referring to  FIG. 3 , the container for the cream-type cosmetics in accordance with the first embodiment of the present invention is operated as follows: when a user presses the upper end of the button part  220 , the button part  220  made of the elastic material moves downward. At this time, the internal pressure of the container body  100  is generated, so that the contents accommodated in the container body  100  push the rubber tip R that closes the contents discharge hole  221  and then are discharged to an upper surface of the button part  220  through the contents discharge hole  221 . 
         [0045]    As such, in order to prevent the piston  110  from moving downward by the internal pressure of the container body  100  that is generated during the pumping operation as the upper end of the button part  220  is pressed, the valve member  140  controlling the air flow is preferably installed at the inner lower end of the container body  100 . The valve member  140  is configured to close the air inlet hole  121  during the pumping operation as the upper end of the button part  220  is pressed. 
         [0046]    Meanwhile, if a user releases the upper end of the button part  220 , the button part  220  moves upward while returning to the original position thereof by its own elastic force. At this time, the piston  110  moves upward in proportion to the discharged amount of the contents. As the piston  110  moves upward, the valve member  140  opens the air inlet hole  121  and thereby air flowing through the air flow hole  130  is introduced into the container body  100  through the air inlet hole  121 . 
         [0047]    Hereinafter, a container for cream-type cosmetics in accordance with a second embodiment of the present invention will be described with reference to  FIGS. 4 to 6 . 
         [0048]      FIG. 4  is an exploded sectional view showing the configuration of the container for the cream-type cosmetics in accordance with the first embodiment of the present invention,  FIG. 5  is an assembled sectional view showing the configuration of the container for cream-type cosmetics in accordance with the second embodiment of the present invention, and  FIG. 6  is a view showing an operational state of the container for the cream-type cosmetics in accordance with the second embodiment of the present invention. 
         [0049]    Referring to  FIGS. 4 to 6 , the container for the cream-type cosmetics in accordance with the second embodiment of the present invention has a button part  220 ′ that is formed on one side of an upper end of a pumping guide cap  200 ′ coupled to an upper portion of the container body  100  by a coupling part  210 ′, moves downward as a user presses the button part and then return to an original position thereof, changes pressure in the container body  100  to guide a pumping operation, and is made of an elastic material. A contents discharge hole  230  is formed in the other side of the upper end of the pumping guide cap  200 ′ to discharge the contents by operating the button part  220 ′. 
         [0050]    An operation of the container for cream-type cosmetics in accordance with the second embodiment of the present invention is as follows. When a user presses the button part  220 ′ formed on one side of the pumping guide cap  200 ′, the button part  220 ′ made of the elastic material moves downward. At this time, the internal pressure of the container body  100  is generated, so that the contents accommodated in the container body  100  push the rubber tip R that closes the contents discharge hole  230  formed in the other side of the pumping guide cap  200 ′, and are discharged to the upper surface of the pumping guide cap  200 ′ through the contents discharge hole  230 . 
         [0051]    As such, in order to prevent the piston  110  from moving downward by the internal pressure of the container body  100 , generated during the pumping operation as the button part  220 ′ is pressed, a valve member  140  is preferably installed at the inner lower end of the container body  100  to control the flow of air, similarly to the first embodiment. The valve member  140  is configured to close the air inlet hole  121  during the pumping operation as the button part  220 ′ is pressed. 
         [0052]    Meanwhile, if a user releases the upper end of the button part  220 ′, the button part  220 ′ moves upward while returning to the original position thereof by its own elastic force. At this time, the piston  110  moves upward in proportion to the discharged amount of the contents. As the piston  110  moves upward, the valve member  140  opens the air inlet hole  121  and thereby air flowing through the air flow hole  130  is introduced into the container body  100  through the air inlet hole  121 . 
         [0053]    Since the remaining configuration is equal in function and structure to the first embodiment of the present invention, a duplicated description thereof will be omitted herein. 
         [0054]    Hereinafter, a container for cream-type cosmetics in accordance with a third embodiment of the present invention will be described with reference to  FIGS. 7 and 8 . 
         [0055]      FIG. 7  is a sectional view showing a configuration of the container for cream-type cosmetics in accordance with the third embodiment of the present invention, and  FIG. 8  is a view showing an operational state of the container for the cream-type cosmetics in accordance with the third embodiment of the present invention. 
         [0056]    Referring to  FIGS. 7 and 8 , the container for the cream-type cosmetics in accordance with the third embodiment of the present invention is configured such that an inner container  500  accommodating contents therein is separately coupled to an interior of the container body  400 , unlike the first embodiment where the contents are accommodated in the container body  100  and the piston  110  is provided in the container body  100  to move upward as the contents are used. This container is characterized in that the inner container  500  is made of a soft material to be contracted as the contents are used. 
         [0057]    The container for the cream-type cosmetics in accordance with the third embodiment of the present invention is configured such that, when a user presses a button part  620  constituting the upper end of a pumping guide cap  600  coupled to the upper portion of the container body  400  via a coupling part  610 , the button part  620  made of an elastic material moves downward. At this time, internal pressure is generated in the inner container  500 , so that the contents accommodated in the inner container  500  push a rubber tip R closing a contents discharge hole  621  and then are discharged to the upper surface of the button part  620  through the contents discharge hole  621 . 
         [0058]    As such, if the pumping operation is performed by pressing the upper end of the button part  620 , the contents are discharged and then the inner container  500  is deformed to be contracted. Here, in order to keep the inner container  500  contracted, the valve member  430  is preferably provided on the inner lower end of the container body  400  to be installed at the valve support  410  and thereby control the air flow. The valve member  430  is configured to close the air inlet hole  411  and thereby block the inflow of air into the container body  400  when the upper end of the button part  620  is pressed, and is configured to open the air inlet hole  411  and thereby allow air flowing through the air flow hole  420  to flow through the air inlet hole  411  into the container body  400  when the upper end of the button part  620  is released. 
         [0059]    Meanwhile, a closing cap  700  is coupled to the upper portion of the container body  400  to surround the pumping guide cap  600 . The closing cap  700  prevents the malfunction of the button part  620 , prevents foreign matter from falling onto the upper end of the button part  620 , and prevents the rubber tip R from being damaged by external impact. 
         [0060]    A pressing protrusion  710  is formed on an upper end in the closing cap  700  to press the upper end of the pumping guide cap  600  and thereby prevent the pumping guide cap  600  from being separated from the container body  400 . 
         [0061]    Hereinafter, a container for cream-type cosmetics in accordance with a fourth embodiment of the present invention will be described with reference to  FIGS. 9 and 10 . 
         [0062]      FIG. 9  is a sectional view showing a configuration of the container for cream-type cosmetics in accordance with the fourth embodiment of the present invention, and  FIG. 10  is a view showing an operational state of the container for the cream-type cosmetics in accordance with the fourth embodiment of the present invention 
         [0063]    Referring to  FIGS. 9 and 10 , the container for cream-type cosmetics in accordance with the fourth embodiment of the present invention is configured such that an inner container  500  accommodating contents therein is separately coupled to an interior of the container body  400 , unlike the second embodiment where the contents are accommodated in the container body  100  and the piston  110  is provided in the container body  100  to move upward as the contents are used. This container is characterized in that the inner container  500  is made of a soft material to be contracted as the contents are used. 
         [0064]    The container for the cream-type cosmetics in accordance with the fourth embodiment of the present invention is configured such that, when a user presses a button part  620 ′ formed on one side of a pumping guide cap  600 ′ coupled to the upper portion of the container body  400  via a coupling part  610 ′, the button part  620 ′ made of an elastic material moves downward. At this time, internal pressure is generated in the inner container  500 , so that the contents accommodated in the inner container  500  push a rubber tip R closing a contents discharge hole  630  formed on the other side of the pumping guide cap  600 ′ and then are discharged to the upper surface of the pumping guide cap  600 ′ through the contents discharge hole  630 . 
         [0065]    As such, if the pumping operation is performed by pressing the button part  620 ′, the contents are discharged and then the inner container  500  is deformed to be contracted. Here, in order to keep the inner container  500  contracted, the valve member  430  is preferably provided on the inner lower end of the container body  400  to control the air flow. The valve member  430  is configured to close the air inlet hole  411  and thereby block the inflow of air into the container body  400  when the button part  620 ′ is pressed, and is configured to open the air inlet hole  411  and thereby allow air flowing through the air flow hole  420  to flow through the air inlet hole  411  into the container body  100  when the upper end of the button part  620 ′ is released. 
         [0066]    Since the remaining configuration is equal in function and structure to the third embodiment of the present invention, a duplicated description thereof will be omitted herein. 
         [0000]    Preferred embodiments of the present invention have been described herein with reference to the accompanying drawings. It is to be understood that the terminology employed herein is for the purpose of description and not of limitation. Therefore, it will be obvious to those skilled in the art that many modifications and variations of the present invention are possible without departing from the spirit and the scope of the appended claims.
