(17) Hereinafter, an embodiment according to the present invention will be described in detail with reference to accompanying drawings.

(18) In general, according to an airtight packaging container, an outer container cap 20 is hinge coupled to an outer container 10 to be opened or closed and a cosmetic container 30 is coupled to an inside of the outer container 10 such that the cosmetic container 30 is opened or closed by a sealing cap 60.

(19) A button 12 from which a coupling protrusion 14 protrudes is installed onto one side surface of the outer container 10. When a hook 24 is formed on the outer container cap 20 and the outer container cap 20 is hinge coupled to the outer container 10, the hook 24 of the outer container cap 20 is coupled to the coupling protrusion 14 of the button 12, such that the outer container cap 20 may be opened or closed.

(20) When the button 12 is pushed to open the outer container cap 20, the coupling protrusion 14 moves back so that the coupling protrusion 14 is released from the hook 24, so the outer container cap 20 can be opened from the outer container 10.

(21) Although the cosmetic container 30 inserted into the outer container 10 is depicted in the drawings, the embodiment is not limited thereto and the cosmetic container 30 and the outer container 10 are integrally formed with each other. Cosmetics may be directly filled into the cosmetic container 30. Alternatively, after cosmetics are impregnated in an impregnated member 40, the impregnated member 40 may be installed in the outer container 10.

(22) When the impregnated member 40 is installed in the cosmetic container 30, a fixing piece 50 is coupled between inner and outer walls 31 and 32 or the cosmetic container 30 such that the impregnated member (40) may be prevented from being separated from the cosmetic container 30.

(23) The sealing cap 60 is closed by putting the sealing cap 60 on the cosmetic container 30. The sealing cap 60 may be closed without any hinges or may be hinge coupled to the cosmetic container 30 as shown in FIG. 6.

(24) When the sealing cap 60 is coupled to the cosmetic container 30 through a hinge, a first hinge block 33 may be formed on an outer side surface of one side of the cosmetic container 30 and a second hinge block 60, which is coupled to the first hinge blocks 33, other may be formed on an outer side surface of one side of the sealing cap 60.

(25) An airtight packaging container according to the present invention includes a cosmetic container 30; and an airtight lid 60 installed onto the cosmetic container 60 in order to prevent cosmetics c, such as foundation or cosmetic cream, containing a large quantity of volatile ingredients such as water or alcohol, from being evaporated or volatilized, wherein the airtight lid 60 includes a sealing plate 52 for covering the cosmetic container 30; and a sealing protrusion wheel 64 formed on a lower surface of the sealing plate 62 and tightly press-inserted into an inlet of the cosmetic container 30, and

(26) a leakage test member 70 formed on the sealing plate 62 of the airtight lid 60.

(27) When the airtight packaging container capable of easily taking a leakage test according to the present invention is given the leakage test, after the leakage test member 70 of the airtight lid 60 is pricked with a syringe needle 93 and air is injected into the cosmetic container 30, the varying of pressure is observed.

(28) Thus, since air must not be leaked through the portion pricked with the syringe needle 93 even though the leakage test member 70 is pricked with the syringe needle 93 and the syringe needle 33 is drawn back from the leakage test member 70, the leakage test member 70 is preferably formed of one of elastomer, silicon rubber and NBR rubber having superior restoration.

(29) The leakage test member 70 may be formed on the airtight lid 60 through a dual injection or an insert injection. Alternatively, after the leakage test member 70 is separately molded, the leakage test member 70 may be assembled with the airtight lid (60). The assembly may be completed through a forcible fitting assembly, by using adhesive or through thermal adhesion.

(30) In the embodiment, the leakage test member 70 and the airtight lid 60 separately molded and assembled through forcible fitting are depicted in the drawings.

(31) The leakage test member 70 may be formed in a cylindrical or polygonal pillar shape. However, when leakage test member 70 may be formed in a polygonal pillar shape, since the edges of the polygonal pillar are weak in air tightness, it is preferable to form the leakage test member 70 in a cylindrical in order to enhance the air tightness with the airtight lid 60.

(32) As shown in FIG. 12, the leakage test member 70 is provided at a center thereof with a coupling groove 72. The sealing plate 62 of the airtight lid 60 is provided with a coupling hole 82 into which the leakage test member 70 is coupled. A coupling protrusion wheel 84 is formed at a center of the coupling hole 82. An upper step groove (86) and a lower step groove (88) are formed by the coupling protrusion wheel (84) as shown in FIG. 12. Furthermore, the coupling protrusion wheel 84 of the sealing plate 62 is coupled into the coupling groove of the leakage test member 70, so that the leakage test member 70 is coupled to the sealing plate 62.

(33) The leakage test member 70 includes an upper ring rim 74 positioned over the coupling groove 72 and a lower ring rim 75 below the coupling groove 72.

(34) Although the diameters of the upper and lower rig rims 74 and 75 are equal to each other, it is preferable that the diameter of the upper rig rim 74 is greater than that of the lower ring rim 74 as shown in FIG. 12, wherein the upper ring rim 74 is received in upper step groove 86, also shown in FIG. 12. The reason is because, when the leakage test member 70 is pricked with the syringe needle 93, the leakage test member 70 is pushed by the syringe needle 93, so that the leakage test member 70 may be separated from the coupling hole 82 of the sealing plate 62 to be press inserted into the cosmetic container 30. To prevent the problem, it is preferable to form the upper rig rim 74 to have a larger size than that of the lower ring rim 74.

(35) Preferably, the lower ring rim 75 is provided at a periphery of a lower end thereof with a taper 76 in order to allow the leakage test member 70 to be easily coupled into the coupling hole 82 of the sealing plate 62.

(36) It is preferable that the leakage test member (70) has a thickness in a range of 1.5 mm to 5.0 mm. The reason is because, when the thickness of the leakage test member 70 is less than 1.5 mm and the syringe needle 93 is drawn back after the leakage test member 70 is pricked with the syringe needle 93, the site pricked with the syringe needle 93 may be exposed to air due to weak restoring force. When the thickness of the leakage test member 70 exceeds 5.0 mm, it is difficult to prick-insert the syringe needle 93 into the leakage test member 70 and the syringe needle 93 may be easily broken or bent. Thus, it is preferable to form the leakage test member 70 to have a thickness in a range of 1.5 mm to 5.0 mm.

(37) It is preferable to form the leakage test member 70 to have a diameter in a range of 3.0 mm to 8.0 mm. The reason is because, although the leakage test member 70 is pushed laterally to be pressed due to a thickness of the syringe needle 93 when the leakage test member 70 is pricked with the syringe needle 93, when the diameter of the leakage test member 70 is less than 3.0 mm, the leakage test member 70 has no room to be pushed and pressed laterally, so that the syringe needle 93 does not pass through the leakage test member 70, thereby being bent or broken. In case that, the diameter of the leakage test member 70 exceeds 8 mm, when the leakage test member 70 is pricked with the syringe needle 93 to inject air into the cosmetic container 30, the internal pressure of the cosmetic container is increased, so that the leakage test member 70 may be separated from the coupling hole 82 of the sealing plate 62 while expanding. Therefore, it is preferable to form the leakage test member 70 to have a diameter in the range of 3.0 mm to 8.0 mm.

(38) The airtight lid 60 may be hinge coupled to the cosmetic container 30, and a handle 68 may be diagonally formed on the hinged part of the airtight lid 60. A coupling protrusion 63 is formed below the handle 68 such that the coupling protrusion 63 is coupled into the coupling groove 36 formed in the cosmetic container 30.

(39) Preferably, after the cosmetic container 30 is closed with the airtight lid 60 by coupling the coupling groove 63 of the airtight lid 60 into the coupling groove 36 of the cosmetic container 30, in order to test whether the cosmetic container 30 is fully closed with the airtight lid 60, air is injected into the cosmetic container 30 through the leakage test member 70 while the leakage test member 70 is pricked with the syringe needle 93 until the internal pressure of the cosmetic container (30) is in the range of 1 kgf/cm.sup.2 to 5 kgf/cm.sup.2. In this case, in order to prevent the airtight lid 60 from being opened by the air pressure in the cosmetic container 30, the coupling protrusion 63 of the airtight lid 60 just be coupled into the coupling groove 36 of the cosmetic container 30 with a predetermined coupling strength. Preferably, the coupling protrusion 63 of the airtight lid 60 is coupled into the coupling groove 36 of the cosmetic container 30 with the predetermined coupling strength, so that, when force in a range of 3 kgf to 5 kgf is applied to the airtight lid 60 against the cosmetic container 30, the airtight lid 60 is opened from the cosmetic container 30.

(40) If the airtight lid 60 is opened at the force less than 3 kgf, when air is introduced into the cosmetic container 30 and the air pressure is increased, the airtight lid 60 is opened, so that it is difficult to perform the leakage test. If the airtight lid 60 is opened at the force exceeding 5 kgf, since most cosmetic customers are women, it is difficult for women to open the airtight lid 60. Thus, preferably, the coupling protrusion 63 of the airtight lid 60 is coupled into the coupling groove 36 of the cosmetic container 30, such that the airtight lid 60 is opened from the cosmetic container 30 when force in the range of 3 kgf to 5 kgf is applied to the airtight lid 60.

(41) In addition, it is preferable to form the air entrance/exit member 66 on the sealing plate 62 of the airtight lid 60 together with the leakage test member 70.

(42) FIG. 11 is a view showing a state that the internal air of a cosmetic container is discharged by pushing a cover plate of an air entrance/exit member applied to the present invention.

(43) Since the internal air of the cosmetic container 30 is compressed when the airtight lid 60 is closed while the sealing protrusion wheel 64 formed on the airtight lid 60 is tightly press-inserted into the inlet of the cosmetic container 30, the internal air pressure of the cosmetic container 30 is raised, so that the closed airtight lid 60 bounces upward to be opened again. To prevent it, the problem of compressing air when the cosmetic container 30 is closed with the airtight lid 60 must be solved.

(44) Thus, according to the present invention, the air entrance/exit member 66 is installed to the airtight lid 60 to prevent air from being compressed while the sealing protrusion wheel 64 of the airtight lid 60 is tightly inserted into the inlet of the cosmetic container 30 when the cosmetic container 30 is closed with the airtight lid 60 to seal the cosmetic container 30.

(45) That is, a coupling hole 621, into which the air entrance/exit member 66 is coupled, is formed in the sealing plate 62, and a plurality of ribs 622 is formed near the coupling hole 621, so that slits 623, through which air flows, are formed between the ribs 622. The air entrance/exit member 66 includes a cover plate 663 for covering an upper portion of the coupling hole 621 of the airtight lid 60, a coupling rod 664 integrally formed below the cover plate 663 and inserted into the coupling hole 621 of the airtight lid 60, and a packing-separation preventing protrusion wheel 665 extending from an end of the coupling rod 664 to prevent the packing 67 from being separated therefrom.

(46) In addition, a packing 67 is fitted with the coupling rod 664 of the air entrance/exit member 66 and provided at a center thereof with a rod coupling hole 671 coupled to the coupling rod 664 of the air entrance/exit member 66. An expansion part 672 is formed on a lower portion of the packing 67 to open or close the coupling hole 621 of the airtight lid 60. A resilient part 673 is formed on an upper portion of the packing 67 to elastically and upwardly support the cover plate 663 of the air entrance/exit member 66 to allow the expansion part 672 to close the coupling hole 621 of the airtight lid 60.

(47) Thus, when the cover plate 663 of the air entrance/exit member 66 is pushed downward while the airtight lid 60 covers the cosmetic container 30, the expansion part 672 of the packing 67 is pressed to move down together with the coupling rod 664 while the resilient part 673 formed on an upper surface of the packing 67 is compressed, so that a gap is created between the expansion part 672 of the packing 67 and the coupling hole 621 of the airtight lid 60, so the compressed air generated in the cosmetic container 30 is discharged through the gap so that the cosmetic container 30 is tightly closed with the airtight lid 60.

(48) In order to test whether the cosmetic container 30 is leaked, after the airtight lid 60 tightly covers the cosmetic container 30 and the leakage test member 70 of the airtight lid 60 is pricked with the syringe needle 93 of a test apparatus described below to inject air, the air pressures are compared with each other after a predetermined time is elapsed.

(49) The apparatus for testing a leakage of an airtight packaging container for easy leakage test according to the present invention, which is formed as described above, will be described in detail below.

(50) FIG. 13 is a schematic view showing an apparatus for testing a leakage of an airtight packaging container for easy leakage test according to the present invention.

(51) The apparatus for taking a leakage test of whether the airtight packaging container is perfectly sealed according to the present invention includes a product seat member 92 for seating the airtight packaging container AC on which a leakage test member 70 is formed; an air injection member 94 for injecting air through the leakage test member 70, the air injection member 94 having a syringe needle 93 mounted thereon; and an air compressor 96 for sucking air through an air suction inlet 95 and injecting the air into a cosmetic container 30 through the syringe needle 93 of the air injection member 94.

(52) The product seat member 92 for seating the airtight packaging container (AC), in which the leakage test member 70 is formed, includes a fixing member for fixing the airtight packaging container (AC). The leakage test member 70 of the cosmetic container 30 is exposed by opening an outer container cap 20.

(53) In addition, the product seat member 92 includes a moving member for moving the product seat member (92) by sensing a position of the air injection member (94) using a sensor to allow the air injection member (94), to which the syringe needle (93) is installed, to move down such that the syringe needle (93) passes through a center of the leakage test member (70).

(54) The air injection member 94, to which the syringe needle 93 is installed to inject air through the leakage test member 70, moves up or down by a motor. In addition, since the syringe needle 93 is worn or broken with use, the syringe needle 93 is installed to be easily detachable from the air injection member 94.

(55) Although the syringe needle 93 must have a predetermined thickness to have strength sufficient to pass through the leakage test member 70, when the syringe needle 93 is too thick, the air injection member 94 pricked with the syringe needle 93 is not elastically deformed but plastic-deformed into the original state. Thus, preferably, the syringe needle 93 has a diameter in the range of 0.2 can to 1.5 mm and formed of stainless steel.

(56) The air injection member 94 may control a descent or ascent distance by using a sensor or a limit switch (which is an automatic control switch for stopping a power motor by blocking the current supplied to the power motor when passing through a predetermined point).

(57) The air compressor 96 sucks air through the air suction inlet 95 and discharges the air through the syringe needle 93. According to the present invention, when the syringe needle 93 passes through the leakage test member 70 of the cosmetic container 30, the outlet 932 of the syringe needle 93 is placed in the cosmetic container 30, so that the air compressor 96 is operated to inject air.

(58) As air is injected, when the internal pressure of the cosmetic container 30 is in the range of 1 kgf/cm.sup.2 to 5 kgf/cm.sup.2, the operation of the air compressor 96 is stopped by the sensor and the air injection member 94 is lifted up so that the syringe needle 93 is withdrawn from the cosmetic container 30.

(59) Thereafter, after the airtight packaging container (AC) is left for a predetermined time, the internal pressure of the cosmetic container 30 is measured to be compared with the internal pressure in injecting air. As the comparison result, when the pressure is lowered, the cosmetic container 30 and the airtight lid 60 entrance/exit member 66 are leaked. If the pressure is not changed, it is determined that there are not any leakages.

(60) Hereinafter, a method of testing a leakage of an airtight packaging container for easy leakage test according to the present invention by using a leakage test apparatus of the present invention will be described in detail.

(61) FIG. 14 is a flowchart sequentially illustrating a method of testing a leakage of an airtight packaging container for easy leakage test according to the present invention.

(62) S10: Step of Seating Airtight Packaging Container

(63) According to the method of taking a leakage test of whether an the airtight packaging container is perfectly sealed, the airtight packaging container AC including the leakage test member 70 to be leak-tested is seated at a product seat member 92.

(64) In this case, preferably, the outer container cap 20 is opened to expose the leakage test member 70 of the cosmetic container 30 and the test target airtight packaging container AC is fixed with the fixing member such that packaging container AC is prevented from moving.

(65) In addition, after the position of the leakage test member 70 is confirmed by using the sensor such that the position of the leakage test member 70 is always maintained, the protract seat member 92 is transferred by the motor, such chat the leakage test member 70 is located below the syringe needle 93.

(66) S20: Step of Moving Down Air Injection Member

(67) By moving down the air injection member 94 on which the syringe needle 93 is mounted, the syringe needle 93 is allowed to pass through the leakage test member 70 of the cosmetic container 30, such that the outlet 332 of the syringe needle 93 is placed in the cosmetic container 30.

(68) The air injection member 94 is formed to move up or down by the motor and the moving up or down of the air injection member 94 is controlled by using the sensor or limit switch such that the outlet 932 of the syringe needle 93 is placed at the center of an inside of the cosmetic container 30.

(69) Since the syringe needle 93 is worn or broken with use, the syringe needle 93 is installed to be easily detachable from the air injection member 94.

(70) S30: Step of Injecting Air

(71) Air is sucked through the air suction inlet 95 by operating the air compressor 96 to inject the air into the cosmetic container 30 through the syringe needle 93 mounted on the air injection member 94.

(72) When the syringe needle 93 passes through the leakage test member 70 of the cosmetic container 30, the outlet 932 of the syringe needle 93 is placed in the cosmetic container 30, so that the air compressor 96 is operated to inject air.

(73) When the cosmetics containing a large quantity of water and volatile ingredients are contained in the cosmetic container 30, even though the internal pressure of the cosmetic container 30 is in the range of 1 kgf/cm.sup.2 to 5 kgf/cm.sup.2, the air must be leaked in order to prevent the water and volatile ingredients from being evaporated and volatilized.

(74) Thus, when the air is injected into the cosmetic container 30, air is injected until the internal pressure of the cosmetic container 30 is in the range of 1 kgf/cm.sup.2 to 5 kgf/cm.sup.2.

(75) S40: Step of Stepping Operation of Air Compressor

(76) After air is injected until the internal pressure of the cosmetic container 30 is in the range of 1 kgf/cm.sup.2 to 5 kgf/cm.sup.2, the operation of the air compressor 96 is stopped by sensing the pressure through the sensor.

(77) S50: Step of Moving Up Air Injection Member

(78) When the internal pressure of the cosmetic container 30 reaches a suitable level so that the operation of the air compressor 96 is stopped, the air injection member 94 on which the syringe needle 93 is mounted is lifted up such that the syringe needle 33 is separated from the cosmetic container 30.

(79) S60: Step of Leaving Airtight Packaging Container

(80) After the injection of air into the cosmetic container 30 is completed, the airtight packaging container AC is left for a predetermined time. Generally, the airtight packaging container AC is left for 5 hours to 48 hours, preferably, 10 hours to 24 hours.

(81) S70: Step of Comparing Air Pressure Variation

(82) After the predetermined time is elapsed, she internal pressure of the cosmetic container 30 is measured and compared with the internal pressure under air injection. If the pressure is lowered, it is determined that a leakage occurs between the cosmetic container 30 and the airtight lid 60 or between the sealing plate 62 and the air entrance/exit member 66. If the pressure is not changed, it is determined that there is no leakage.

(83) The airtight packaging container for easy leakage test, and a method and an apparatus for testing a leakage by using the airtight packaging container described in this disclosure are for an illustrative purpose only and the present invention is not limited thereto.

(84) Thus, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art within the spirit and scope of the present invention and they will fall within the scope of the present invention.
