BEST MODE

Mode for Invention

(8) Hereinafter, the present invention will be described in detail with reference to accompanying drawings.

(9) First, as shown in FIGS. 4 and 5, a cosmetic container, which is capable of storing and discharging two kinds of contents, includes a lower container body 200 coupled to a lower cap 201 in a lower part of the cosmetic container 100 and receiving first and second containers 202 and 203 which are coupled to a lower cap 201 and filled with cosmetic contents; an airless pump (300) including a piston part (301) provided on opening parts of the first and second containers (202 and 203), and a piston housing (303) having a pressing protrusion (302) and provided on an outer periphery part of the piston part (301); a piston hole 204 formed at an upper side of the lower container body 200 to receive the piston housing 303; a button housing 400 provided at a lower side of the lower container body 200 through an under-cut scheme and coupled to an edge of the piston hole 204; side buttons 500 which are installed into button receiving holes 401 provided at both sides of an outer periphery part of the button housing 400 and which slides while pressing the pressing protrusion 302; and a mixture discharge member 700 coupled to valve holes 402 for receiving a discharge valve 600 at an upper side of the button hosing 400 such that the cosmetic contents discharged by the airless pump 300 is discharged through the discharge valve 600, wherein the mixture discharge member 700 is concavely formed in a dish shape and is coupled to an edge of the button housing 400, discharge holes 701 are formed in the mixture discharge member 700, through which the cosmetic contents are discharged by the airless pump 300; and an opening/closing nozzle unit 702 is provided to the discharge holes 701 and coverts the discharge pressure of the cosmetic contents discharged therethrough by the airless pump 300 into a low pressure.

(10) Discharge ribs 701 are formed on an inner periphery of the discharge hole 701.

(11) The number of the discharge ribs 701 is preferably set according to the quantity of the discharge contents.

(12) The opening/closing nozzle unit 702 includes a blocking piece 702a to which the discharge pressure is directly applied by the airless pump 300, a transfer hole 702b for guiding the cosmetic contents which are transferred while being dispersed into both sides by the blocking piece 702a, and an opening/closing wing piece 702c for discharging the cosmetic contents transferred upward by the guide of the transfer hole 702b at small quantity.

(13) The opening/closing nozzle unit 702 allows the discharge pressure of the cosmetic contents discharged by the airless pump 300 to be converted into a low pressure and may be formed of an elastic material such that the cosmetic contents may be discharged even at a low pressure through the discharge hole 701.

(14) The operation of the present invention described above is as follows.

(15) As shown in FIG. 6a, when the side button 500 at one side is pushed into the inside of the button housing 400 in order to selectively use one of the first and second storing containers 202 and 203 is to be selectively used, while the side button 500 slides into the button housing 400, the inclined surface formed at a lower side of the side button 500 presses downward the pressing protrusion 302 protruding from the upper portion of the airless pump 300.

(16) Thus, the airless pump 300 moves down and the cosmetic contents in a temporary storage room S rise along a transfer passage of the piston part 301 while a content transfer passage in the airless pump 300 is opened, so that the cosmetic contents are transferred into the discharge hole 701. The discharge pressure of the cosmetic contents rising by the airless pump 300 is converted into a low pressure due to the resistance of blocking piece 702a provided to the opening/closing 702 so that the cosmetic contents are dispersed into both sides by the blocking piece 702a and move up along the transfer hole 702b.

(17) After the cosmetic contents mow up along the transfer-hole 702b as described above, as shown in FIG. 8, when the cosmetic contents arrives on the opening/closing wing piece 702c, while an end of the opening/closing wing piece 702c rises up by a predetermined distance due to the cosmetic contents having the converted low pressure, a small amount of cosmetic contents is discharged into the discharge hole 701 provided at one side of the mixture discharge member 700.

(18) When the pressure on the side button 500 is removed after the cosmetic contents are discharged through the mixture discharge member 700, the airless pump 300 moves up by the elastic member provided in the airless pump 300 and at the same time, the pressing protrusion 302 pushes the inclined surface of the side button 500 to allow the side button 500 to return to the original position. In addition, as shown in FIG. 9, while the piston part 301 in the airless pimp 300 moves up, the transfer passage of the cosmetic contents is shut off to generate vacuum pressure from the airless pump 300, so that the cosmetic contents in the first storage container 202 moves up to be filled into the temporary storage roove S while the check valve CV is opened.

(19) Meanwhile, when the mixture, which is obtained by simultaneously discharging two cosmetic contents stored in each of the first and second storage containers 202 and 203 to be mixed with each other, is used, the side buttons 500 of both sides are simultaneously pushed. In this case, the operations of the side buttons 500 and the airless pump 300 are as follows.

(20) That is, as shown in FIG. 6b, when both side buttons 500 are pushed into the button housing 400, while the side buttons 500 slide into the button housing 400, the inclined surfaces formed at lower sides of the side buttons 500 press downward the pressing protrusions 302 protruding from the upper portions of the airless pumps 300.

(21) Thus, the airless pumps 300 move down and the cosmetic contents in the temporary storage rooms S rise along the transfer passages of the piston parts 301 while the content transfer passages in the airless pumps 300 are opened, so that the cosmetic contents are transferred into the discharge holes 701. The discharge pressures of the cosmetic contents rising by the airless pumps 300 are converted into the low pressures due to the resistance of blocking pieces 702a provided to the opening/closing unit 702 so that the cosmetic contents are dispersed into both sides by the blocking pieces 702a and move up along the transfer holes 702b.

(22) After the cosmetic contents move up along the transfer holes 702b as described above, when the cosmetic contents arrive on the opening/closing wing pieces 702c, while the ends of the opening/closing wing pieces 702c rise up by the predetermined distance due to the cosmetic contents having the converted low pressure, small amounts of cosmetic contents are discharged into the discharge holes 701 provided at both sides of the mixture discharge member 700.

(23) When the pressures on both side buttons 500 are removed after the cosmetic contents are discharged through the mixture discharge member 700, the airless pumps 300 move up by the elastic members provided in both airless pumps 300 and at the same time, the pressing protrusions 302 push the inclined surfaces of both side buttons 500 to allow both side button 500 to return to the original positions, respectively. In addition, while the piston parts 301 in the airless pumps 300 move up, the transfer passages of the cosmetic contents are shut off to generate vacuum pressure from the airless pumps 300, so that the cosmetic contents in the first and second storage containers 202 and 203 move up to be filled into both temporary storage rooves S while the check valves CV are opened.

(24) Although an exemplary embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
