     TECHNICAL FIELD 
     The present invention relates to a compact container having a ring button member provided thereon and having a discharge plate formed by insert injection molding, and more particularly, to a compact container having a ring button member provided thereon and having a discharge plate formed by insert injection molding, wherein a discharge device is installed inside the compact container to discharge a cosmetic material, pallets for pressurizing the discharge device are provided, and the discharge plate is formed as a single component between an upper pallet and a lower pallet of the pallets through the insert injection molding, so that an assembly process for separately coupling the discharge plate and the upper/lower pallets to the compact container is removed so as to improve productivity, and a defective product is prevented from occurring in the process of assembling the discharge plate and the upper/lower pallets. 
     BACKGROUND ART 
     In general, makeup is for making a beautiful part of a body more beautiful, and for compensating for a weak point of the body. Women put on facial makeup by using basic cosmetics or color cosmetics to make their appearance more beautiful. 
     The color cosmetics are classified into a base makeup used for making a skin color uniform and covering defects, and a point makeup used for partially enhancing a three-dimensional effect of lips, eyes, or nails. The base makeup includes a makeup base, a foundation, and a powder, and the point makeup includes a lipstick, an eye liner, and mascara. 
     The foundation is classified into a solid foundation, a liquid foundation and a gel foundation according to the form of the cosmetic material. Although the solid foundation produces an effect of excellently covering the skin, the solid foundation may be agglomerated when correcting the makeup. In addition, although the liquid foundation provides a good close contact feel, the persistency of the liquid foundation is weak. 
     Thus, in recent years, the gel foundation, which gives fresh feelings upon use by imparting a feeling of lightness and moisture, is increasingly used. 
     However, in case of filling the gel foundation in a typical container for use, the same amount of cosmetic materials may not be used every time the makeup is performed, and the cosmetic materials are contaminated with bacteria and wastes because a hand of a user or a puff repeatedly makes contact with the cosmetic materials. 
     To solve the problems described above, as shown in  FIG. 1 , there is provided Korean Patent No. 10-1566114 which discloses a cosmetic container. The related art includes a discharge device for discharging a cosmetic product to an outside, and a discharge plate provided at one side of the discharge device where the cosmetic product is discharged from the discharge device, having at least one discharge port, and exposed to the outside to allow a puff of a user to make contact with the discharge plate, wherein the cosmetic product is discharged from the discharge device as the discharge plate is pressed. 
     The related art further includes a sealing member or a packing material closely interposed between a dispersion part and the discharge plate, so that the cosmetic product may be prevented from leaking to a part other than the discharge port of the discharge plate. 
     However, in the related art, when a center of the discharge plate is not pressed, an up-down movement member is inclined and caught in an inner periphery of the sealing member. Accordingly, a cosmetic material is pumped only when the user presses a center part of the discharge plate vertically, so that a pressing position is limited when pressing the discharge plate, which causes inconvenience in use. 
     In addition, since the related art has a structure that the sealing member or the packing material is coupled between a guide plate and the discharge plate to prevent the leakage of the cosmetic products, productivity is decreased due to an increase in an assembly process during production of products, and defective products occur in the assembly process.

     In addition, the inner container bottom surface  33  of the inner container  30  is formed with an air passage hole  34  through which external air is introduced. 
     In addition, a discharge device support  40  having a plate shape is coupled to an upper portion of the inner container  30 , in which the discharge device support  40  is coupled to the upper portion of the inner container  30 , and the discharge device  50  is installed on an upper portion of the discharge device support  40 . 
     A cylinder  51  is provided at a center of the discharge device support  40 , a bushing coupling groove  41  to which a bushing  53  of the discharge device  50  is coupled is formed at an outer side of the cylinder  51 , and a lower extension protrusion wheel  42  extends downward from an outer side of the discharge device support  40 . 
     In the drawings of the present invention, it is shown that the cylinder  51  is integrally formed at the center of the discharge device support  40 , so that the bushing  53  is installed on the outer side of the cylinder  51  to prevent a piston  55  fitted with a piston ring  56  from being separated from the cylinder  51 , and an inner horizontal extension piece  532  is formed inward of a through-hole  531  of the bushing  53 . However, the discharge device support  40  and the cylinder  51  may be separately formed, and the discharge device  50  may be provided at the center of the discharge device support  40 . In this case, the bushing  53  described in the present invention may not be required. 
     A coupling protrusion  421  is formed on an outer periphery of the lower extension protrusion wheel  42  of the discharge device support  40  so as to be coupled to the coupling groove  362  of the inner container  30 , and a mounting protrusion wheel  422  protrudes from a top of the coupling protrusion  421  so as to be fitted between the first and second mounting protrusions  14  and  15  of the outer container  10 . 
     The discharge device  50  is installed on the discharge device support  40  to discharge the cosmetic material accommodated in the inner container  30  to an outside. 
     The discharge device  50  may be a pump for pumping the cosmetic material accommodated in the inner container  30 . 
     The discharge device  50  may include the cylinder  51  formed at the center of the discharge device support  40  and formed on a bottom surface thereof with a content suction hole  58 , a suction valve plate  52  mounted on a bottom surface of the cylinder  51  to selectively open and close the content suction hole  58 , the bushing  53  placed on an upper end of the cylinder  51  and coupled to the outer side of the cylinder  51 , an elastic member  54  mounted on an upper portion of the bushing  53  or the upper portion of the discharge device support  40  to elastically support the pallet  60 , the piston  55  provided at an inner side of the cylinder  51 , and the piston ring  56  fitted on the outer side of the piston  55  while making close contact with an inner side surface of the cylinder  51 . 
     The through-hole  531  through which the piston  55  and the piston ring  56  pass is formed at a center of the bushing  53 , the inner horizontal extension piece  532  extends inward of the through-hole  531 , and a plurality of elastic member mounting parts  533  are provided at an outer side of the through-hole  531 . 
     The bushing  53  is provided with a first latching sill  536  to which an anti-separation part  647  of the pallet  60  is coupled, and the first latching sill  536  serves to prevent the pallet  60  from being separated from the discharge device  50 . 
       FIG. 6  is a partial perspective view and partial sectional view showing a pallet of the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding according to the present invention. 
     The pallet  60  is coupled to an upper portion of the discharge device  50  to fix the discharge plate  80  and to vertically move so as to pressurize the discharge device  50 . 
     A pair of compression protrusions  61  facing each other in a diagonal direction are formed on an outer periphery of the pallet  60 , in which the compression protrusions  61  of the pallet  60  are formed to correspond to positions of compression grooves  71  of the ring button member  70  so as to be fitted to the compression grooves  71  of the ring button member  70 , respectively. 
     The compression protrusion  61  of the pallet  60  has a semicircular or circular shape so that the compression protrusion  61  may be easily rotated within the compression groove  71  of the ring button member  70 . 
     As shown in  FIG. 6 , the pallet  60  includes the upper pallet  62  and the lower pallet  64 , in which the discharge plate  80  is insert-injection-molded between the upper pallet  62  and the lower pallet  64 . 
     In addition, a bottom surface of the upper pallet  62  and a top surface of the lower pallet  64  are integrally fused to each other at an outer side of the discharge plate  80  through the insert injection molding. 
     In other words, after the lower pallet  64  is injection-molded, the discharge plate  80  is seated on a support part  642  and a seating part  644  of the lower pallet  64 , and the upper pallet  62  is injection-molded, so that the lower pallet  64  and the upper pallet  62  may be integrally fused to each other at the outer side of the discharge plate  80 . 
     Therefore, when the compact container is assembled, a process of assembling the discharge plate  80  and the upper and lower pallets  62  and  64  may be reduced so as to improve productivity, and the cosmetic material discharged by the discharge device  80  may be prevented from leaking between the upper pallet  62  and the lower pallet  64 . 
     In addition, as shown in  FIG. 5 , in the compact container according to the present invention, a fusion groove  62   a  is formed in a lower portion of the upper pallet  62 , and a fusion protrusion part  64   a  corresponding to the fusion groove  62   a  is provided on an upper outer side of the lower pallet  64 , such that a fusing surface of the upper pallet  62  and the lower pallet  64  is widened, and the upper pallet  62  is insert-injection-molded while surrounding an outer side of the lower pallet  64 . Accordingly, the upper pallet  62  and the lower pallet  64  are completely fused to each other without being separated from each other. 
     As shown in  FIG. 6 , when the upper pallet  62  is insert-injection-molded with the discharge plate  80 , a covering length l of the upper pallet  62  for an upper outer side of the discharge plate  80  is about 0.5 mm to 2.0 mm. In a case where the upper pallet  62  covers the upper outer side of the discharge plate  80  by less than 0.5 mm, a covering area of the upper pallet  62  for a top surface of the discharge plate  80  is small, so that the discharge plate  80  is not firmly fixed to the pallet  60 , causing the upper discharge plate to be separated upward. In addition, in a case where the upper pallet  62  covers the upper outer side of the discharge plate  80  by more than 2.0 mm, a covering area of the upper pallet  62  for the top surface of the discharge plate  80  is widened, so that utilization of space over the top surface of the discharge plate  80  becomes inefficient. 
     An inner end of the upper pallet  62  has a stepped configuration, and, as shown in  FIG. 6 , a height h 1  from the top surface of the discharge plate  80  to the inner end of the upper pallet  62  is preferably 0.3 mm to 1.5 mm. 
     In a case where the height h 1  from the top surface of the discharge plate  80  to the inner end of the upper pallet  62  is less than 0.3 mm, an end portion of the upper pallet  62  is too thin, so that the inner end of the upper pallet  62  may be easily broken even in a minute impact during a manufacturing process or when distributed and carried. In addition, in a case where the height h 1  from the top surface of the discharge plate  80  to the inner end of the upper pallet  62  exceeds 1.5 mm, when the cosmetic material discharged onto the top surface of the discharge plate  80  is put on a puff while being rubbed with the puff, the cosmetic material may be contaminated since the cosmetic material caught in an edge groove between the top surface of the discharge plate  80  and the inner end of the upper pallet  62  so as to remain in the edge groove. 
     In addition, a height h 2  from the top surface of the discharge plate  80  to a top surface of the upper pallet  62  is 1.5 mm to 5.5 mm. In a case where the height h 2  of the upper pallet  62  is less than 1.5 mm, when the cosmetic material discharged onto the top surface of the discharge plate  80  is put on the puff while being rubbed with the puff, the cosmetic material may go over the upper pallet  62  so as to fall between the upper pallet  62  and the ring button member  70 , so that an inside of the compact container may be contaminated. In a case where the height h 2  exceeds 5.5 mm, a thickness of the compact container becomes large due to the height h 2  of the upper pallet  62 , resulting in reduced portability. 
     In addition, the support part  642  for supporting the discharge plate  80  so that the discharge plate  80  is not bent when the discharge plate  80  is pressed is integrally formed at a center of the lower pallet  64 , in which a top surface of the support part  642  makes close contact with a central bottom surface of the discharge plate  80 . 
     The lower pallet  64  is formed at the outer side thereof with a discharge passage  641  through which the cosmetic material discharged by the discharge device  50  passes. 
     A first lower extension protrusion wheel  643  extends from a bottom of the support part  642  of the lower pallet  64 , and the first lower extension protrusion wheel  643  is coupled to the piston  55  of the discharge device  50 . 
     A second lower extension protrusion wheel  645  fitted to an outer side of the piston ring  56  of the discharge device  50  extends downward while being spaced outward from the first lower extension protrusion wheel  643  of the lower pallet  64  by a predetermined distance. 
     The anti-separation part  647  for preventing the pallet  60  from being separated from the compact container extends downward from an outer side of the second lower extension protrusion wheel  645  of the lower pallet  64 , in which a second latching sill  648  is formed at a bottom of the anti-separation part  647  so as to be fastened to the first latching sill  536  of the bushing  53 . 
     A distribution passage  646  is formed in an upper portion of the lower pallet  64  to allow the cosmetic material which has passed through the discharge passage  641  to be spread widely, and the distribution passage  646  is provided at an outer side thereof with a seating part  644  on which the discharge plate  80  is seated. 
       FIG. 9  is a partial sectional view showing a mesh net provided on an upper portion of a distribution passage of the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding according to the present invention. 
     As shown in  FIG. 9 , a mesh net  649  may be provided on an upper portion of the distribution passage  646  of the lower pallet  64 , in which the mesh net  649  allows the cosmetic material pumped by the discharge device  50  to be discharged as fine particles without being agglomerated. 
     The upper pallet  62  may have a ring shape such that the top surface of the discharge plate  80  is exposed to the outside. 
     The ring button member  70  has a ring shape, is coupled to an outer side of the pallet  60 , and is formed at an inner periphery thereof with a pair of compression grooves  71  facing each other in a diagonal direction. 
     The fastening protrusion  78  protrudes outward from an outer periphery of the ring button member  70  on an opposite side of the compression groove  71 , in which the fastening protrusion  78  is fitted to the fastening groove  18  of the outer container  10  to prevent the ring button member  70  from being separated from the outer container  10 . 
     An axial protrusion  73  is formed on one side of the outer periphery of the ring button member  70  so as to be fitted to the axial coupling groove  16  of the outer container  10 . 
     The compression groove  71  of the ring button member  70  has a semicircular or polygonal shape. 
     A diameter of the compression protrusion  61  of the pallet  60  is smaller than an inner diameter of the compression groove  71  of the ring button member  70 . 
     In other words, the compression protrusion  61  of the pallet  60  has a semicircular or circular shape, the compression groove  71  of the ring button member  70  has a semicircular shape, and the diameter of the compression protrusion  61  is smaller than the inner diameter of the compression groove  71  so as to allow the compression protrusion  61  to be fitted to the compression groove  71 . Therefore, when the user pressurizes the ring button member  70  or the discharge plate  80  to discharge the cosmetic material, even if the ring button member  70  or the discharge plate  80  is pressurized in an inclined state, the compression groove  71  of the ring button member  70  is idly rotated at an upper portion of the compression protrusion  61  of the pallet  60  so that a center of pressurization may be changed, and thus, the pallet  60  may vertically pressurize the discharge device  50 . 
     The discharge plate  80  is insert-injection-molded between the upper pallet  62  and the lower pallet  64  of the pallet  60 . 
     The discharge plate  80  is formed with a plurality of discharge ports  82  for discharging the cosmetic material pumped by the discharge device  50  to the outside. 
     The discharge plate  80  may be formed of a metal, a synthetic resin, or a fiber material. 
     When the discharge plate  80  is formed of a synthetic resin material, the discharge plate  80  is preferably formed of at least one material among an epoxy resin, an amino resin, a phenol resin, polyester, polyethylene, an acrylic resin, polypropylene, polystyrene, polyvinyl chloride, Teflon, nylon, and a polyacetal resin. 
     In addition, the discharge plate  80  may be formed of various materials such as a metal alloy and a plated metal.

     Hereinafter, a method of assembling the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding, which has a configuration as described above, will be described with reference to the accompanying drawings. 
     In order to assemble the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding according to the present invention, first, as shown in  FIGS. 3 to 5 , the inner container  30  is mounted inside the outer container  10  having one side hinge-coupled with the outer container lid  20 . 
     Next, the push plate  32  is fitted into the inner container  30 , the cosmetic material is injected into the inner container  30 , and the discharge device support  40  is coupled to the upper portion of the inner container  30 , such that the lower extension protrusion wheel  42  of the discharge device support  40  is fitted between the inner wall  35  and the outer wall  36  of the inner container  30  while the mounting protrusion wheel  422  of the lower extension protrusion wheel  42  is fitted between the first and second mounting protrusions  14  and  15  of the outer container  10 . 
     Then, the discharge device  50  is installed on the discharge device support  40 , and the pallet  60  is coupled to the upper portion of the discharge device  50 , such that the anti-separation part  647  of the pallet  60  is inserted into an anti-separation part insertion groove  535  of the discharge device  50 , and the second latching sill  648  of the anti-separation part  647  is fastened to the first latching sill  536  of the discharge device  50 . 
     At the same time, the first lower extension protrusion wheel  643  and the second lower extension protrusion wheel  645  of the pallet  60  are coupled to the piston  55  and the piston ring  56  of the discharge device  50 , respectively. 
     At this time, the bottom surface of the upper pallet  62  and the top surface of the lower pallet  64  are integrally fused to each other at the outer side of the discharge plate  80  through the insert injection molding, and the central bottom surface of the discharge plate  80  makes close contact with the support part  642  of the lower pallet  64 . 
     Finally, the ring button member  70  is mounted on an upper portion of the pallet  60 , in which the compression protrusion  61  of the pallet  60  and the compression groove  71  of the ring button member  70  are aligned in positions thereof, the axial protrusion  73  of the ring button member  70  is fitted to the axial coupling groove  16  of the outer container  10 , and the fastening protrusion  78  of the ring button member  70  is fitted to the fastening groove  18  of the outer container  10 , thereby completely assembling the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding according to the present invention. 
     Hereinafter, the use of the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding, which is assembled as described above, will be described. 
       FIG. 7  is a sectional view taken along line A-A representing that a cosmetic material is discharged by pressing the ring button member of the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding according to the present invention, and  FIG. 8  is a sectional view taken along line A-A representing that the cosmetic material is sucked into a discharge device as the ring button member ascends in the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding according to the present invention. 
     In order to use the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding according to the present invention, first, as shown in  FIG. 7 , the outer container lid  20  is opened, and a top surface of the ring button member  70  is pressurized. 
     When the ring button member  70  is pressurized, the ring button member  70  is inclined so as to move downward, and the pallet  60  mounted on a lower side of the ring button member  70  is moved downward together with the ring button member  70 . 
     In this case, the compression protrusion  61  of the pallet  60  has a semicircular or circular shape, the compression groove  71  of the ring button member  70  has a semicircular shape, and the diameter of the compression protrusion  61  is smaller than the inner diameter of the compression groove  71  so as to allow the compression protrusion  61  to be fitted to the compression groove  71 , so that, even if the ring button member  70  is pressurized in an inclined state, the compression groove  71  of the ring button member  70  pressurizes on the upper portion of the compression protrusion  61  of the pallet  60  so as to allow the pallet  60  to vertically pressurize the discharge device  50 . 
     Thereafter, as the piston  55  and the piston ring  56  of the discharge device  50  coupled to a bottom of the pallet  60  are moved downward together with the pallet  60  due to the downward movement of the pallet  60 , a volume inside the cylinder  51  is reduced. 
     Accordingly, a pressure is generated inside the cylinder  51 , and the cosmetic material in the cylinder  51  tends to be discharged to the outside by the pressure, so that a discharge pressure is generated so as to allow the suction valve plate  52  to close the content suction hole  58  formed in the bottom surface of the cylinder  51 . 
     At the same time, the cosmetic material accommodated in the cylinder  51  flows between the piston  55  and the piston ring  56 , passes through the discharge passage  641  of the lower pallet  64 , passes through the distribution passage  646  of the lower pallet  64 , and is discharged through the discharge port  82  of the discharge plate  80 . 
     Thereafter, when the pressurization of the ring button member  70  is released as shown in  FIG. 8 , the pallet  60  is moved upward by elasticity of the elastic member  54  which elastically supports the pallet  60 , and the piston  55  and the piston ring  56  coupled to a bottom of the lower pallet  64  of the pallet  60  is moved upward together with the pallet  60 , so that the volume inside the cylinder  51  becomes large so as to generate a vacuum pressure. 
     The suction valve plate  52  is lifted by the vacuum pressure generated inside the cylinder  51  so as to open the content suction hole  58  formed in the bottom surface of the cylinder  51 . Accordingly, the cosmetic material accommodated in the inner container  30  is introduced into the cylinder  51  through the content suction hole  58  while the push plate  38  installed in the inner container  30  is moved upward. 
     As described above, although the compact container having the ring button member provided thereon and having the discharge plate formed through the insert injection molding according to one embodiment of the present invention has been described for illustrative purposes, the present invention is not limited thereto. It will be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention as disclosed in the appended claims.
