DETAILED DESCRIPTION OF THE INVENTION

(15) Hereinafter, a foundation container including a contents diffusion member and a discharge pump having a shorter stroke according to the embodiment of the present invention will be described with reference to the accompanying drawings.

(16) According to the present invention as shown in FIGS. 5 and 6, the foundation container, which includes an outer container body 100 and an outer container lid 150 hinged with the outer container body 100 to be open or closed, further includes an inner container body 300 formed in the outer container body 100; an auxiliary container 370 formed in the inner container body 300 to receive contents; an inner container lid 400 to cover an upper portion of the inner container body 300; an inner container blocking plate 350 coupled to an inside of an upper portion of the inner container body 300; a discharge pump 600 coupled to the center of the inner container blocking plate 350; a contents diffusion member 700 coupled to the discharge pump 600; and an impregnation member 800 coupled to an upper portion of the contents diffusion member 700, in which the discharge pump 600 includes a pump body 10, a pump upper body 20, a pump lower body 30, a suction valve plate 40, a discharge valve 50, and an elastic member 60.

(17) In the discharge pump 600 of FIGS. 7 and 8, if the pump upper body 20 or a top surface of the discharge valve 50 is pressed so that the pump upper body 20 is moved down, the volume of a temporary storage TR in the pump body 10 is reduced, so that the pressure is increased in the temporary storage TR. Accordingly, the suction valve plate 40 closes a contents suction port 32, a valve protrusion wheel 52 contacting the contents discharge port 22 spreads due to the pressure such that the contents in the temporary storage TR pass though the spread space between the contents discharge port 22 of an extension protrusion wheel 26 and the valve protrusion wheel 52. Then, the contents pass through a passage 24 that serves as a gap between the pump upper body 20 and the discharge valve 50. Then, discharge pressure acts on the upper periphery of the discharge valve 50 to spread a gap between the upper surface of the pump upper body 20 and the upper peripheral edge of the discharge valve 50 so that the contents are discharged through the gap.

(18) If the force applied to the upper surface of the pump upper body 20 or the discharge valve 50 is removed, vacuum pressure is generated when the space of the temporary storage TR in the pump main body 10 becomes larger as the pump upper body 20 is moved up by the restoring force of the elastic member. When the pump upper body 20 is moved up, the space between the valve protrusion wheel 52 of the discharge valve 50 and the contents discharge port 22 of the extension protrusion wheel 26 is closed, and the central portion of the suction valve plate 40 is moved up due to the vacuum force. Accordingly, the boundary of an open/close line 41 is opened to permit the contents to move to the temporary storage TR through the space between the suction valve plate 40 and the contents intake port 32. If the vacuum pressure disappears from the temporary storage TR according to the movement of the contents, the open/close line, which is opened due to the self-elasticity of the suction valve plate 40, is recovered to an original state and closed, so that the suction valve plate 40 closes the contents suction port 32.

(19) Additionally, the inner container body 300 may be formed integrally with the outer container body 100.

(20) Further, a sealing ring 360 may be further attached to the outer circumferential surface of the inner container blocking plate 350 to enhance sealing force.

(21) Preferably, a fixture 330 is coupled onto the inner container body 300 to prevent the inner container blocking plate 350, the contents diffusion member 700, and the impregnation member 800 from being separated from the inner container body 300.

(22) A puff built-in space 410 may be formed in the upper portion of the inner container lid 400 according to the present invention, and a puff cover 420 may further be formed on the inner container lid 400.

(23) Additionally, and preferably, a puff 900 is received in the puff built-in space 410 of the inner container lid 400 according to the present invention.

(24) The outer container body 100 receives the inner container body 300 therein, and the button 102 may be separated from a hook 151 of the outer container lid 150 as a user presses the button 102 so that a locking protrusion 101, which extends upward from the button 102, is easily moved back.

(25) The outer container lid 150, which covers the upper portion of the outer container body 100, is hinged with the outer container body 100 to open or close the outer container body 100.

(26) The outer container lid 150 is formed at one side thereof with the hook 151, and the hook 151 has the shape of a protrusion corresponding to the locking protrusion 101.

(27) The inner container body 300 is provided therein with an auxiliary container 370, and the auxiliary container 370, which receives contents therein, has a thin thickness and includes a deformable material.

(28) The auxiliary container 370 may include one of vinyl, synthetic resin material, ordinary rubber, elastomer, silicon rubber, or NBR rubber.

(29) The auxiliary container 370 may be formed through a double injection process together with the inner container body 300. The auxiliary container 370 and the inner container body 300 are separately formed and assembled together.

(30) The present invention will be described based on the structure in which the auxiliary container 370 is formed separately from the inner container body 300 and assembled with the inner container body 300 below.

(31) The inner container body 300 includes an outer wall 301, an inner wall 302, and a hinge bracket 311 for the coupling with the inner container lid 400.

(32) Although the inner container body 300 may be formed integrally with the outer container body 100, the following description will be made while focusing on the inner container body 300 according to the present invention.

(33) The outer wall 301 and the inner wall 302 form the lateral sides of the inner container body 300, and a predetermined space is formed between the outer wall 301 and the inner wall 302.

(34) The hinge bracket 311 is formed on one lateral side of the outer wall 301 for the hinge-coupling with the inner container lid 400 to cover the inner container body 300, and coupled to the outer wall 301 by a hinge pin 310.

(35) The inner container blocking plate 350 is located on the upper end of the inner container body 300 and formed at the center of the inner container blocking place 350 is a pump body 10 to prevent the leakage of the contents.

(36) The inner container blocking plate 350 is formed in an upper end thereof with a coupling groove 353, and a coupling protrusion 753 formed at an end of a diffusion plate 750 of the contents diffusion member 700 is fitted into the coupling groove 353, thereby preventing the diffusion plate 750 from being moved.

(37) The inner container blocking plate 350 may be formed integrally with the pump body 10, or may be formed separately from the pump body 10.

(38) The following description will be described while focusing on the structure that the inner container blocking plate is formed integrally with the pump body according to the present invention.

(39) The pump body 10 is formed at the center of the inner container blocking plate 350 to serve as a cylinder of the pump. A hollow formed in the center of the pump body 10 serves as the temporary storage T in which contents stay until being discharged after sucked.

(40) The sealing ring 360 may be further coupled to the outer peripheral surface of the inner container blocking plate 350 to enhance sealing force.

(41) The sealing ring 360 may include one of ordinary rubber, elastomer, silicon rubber, NBR rubber, or synthetic resin material having excellent elasticity.

(42) The discharge pump 600 includes the pump body 10, the pump upper body 20, the pump lower body 30, the suction valve plate 40, the discharge valve 50, and the elastic member 60.

(43) The pump body 10 has an inner sidewall 11 penetrating through the top and bottom to form a hollow at the center of the inner sidewall 11. A connecting piece 13 is integrally formed at the center of an outside of the inner sidewall 11 and a bending wheel 14 is integrally formed with an inside of the upper side of the inner sidewall 11.

(44) The pump body 10 is located at the center of the inner container blocking plate 350 and may be integrally formed with the inner container blocking plate 350, or may be formed separately from the inner container blocking plate 350. The following description will be made while focusing on the structure that the pump body 10 is formed integrally with the inner container blocking plate 350 according to the present invention.

(45) The inner sidewall 11 serves a cylinder of a pump, and the hollow formed in the center of the pump body 10 serves as the temporary storage TR.

(46) The connection piece 13 serves as a support on which an elastic member 69 is placed, and an outer sidewall 12 may be further formed at the outside of the connection piece 13.

(47) The outer sidewall 12 may be utilized as an auxiliary unit for coupling the pump lower body 30 to a lower portion of the pump body 10.

(48) The bending protrusion wheel 14 protruding inward from the upper portion of the inner sidewall 11 maintains air tightness when a vertical wall 21 of the pump upper body 20 is fitted into the pump body 10 and vertically moved. Preferably, an inner diameter of the bending protrusion wheel 14 is equal to or less than outer diameter of the vertical wall 21 of the pump upper body 20. Most preferably, when the inner diameter of the bending protrusion wheel 14 is 0.01 mm-0.5 mm less than the outer diameter of the vertical wall 21 of the pump upper body 20, the air tightness is maintained while the pump upper body 20 may be easily moved up and down in the pump body 10.

(49) Alternatively, if the vertical wall 21 of the pump upper body 20 is larger than the inner diameter of the bending protrusion wheel 14 that is fitted into the pump body 10, then the bending protrusion wheel 14 is bent outward to receive elastic force so that the bending protrusion wheel 14 has the air tightness with respect to the vertical wall 21 of the pump upper body 20.

(50) A sealing protrusion wheel 15 may be further formed downward of the connection piece 13. The sealing protrusion wheel 15 adds sealing force in the coupling with the pump lower body 30. Additionally, a coupling groove 16 is formed inward of a lower end of the outer sidewall 12 to serve as a unit for the coupling with the pump lower body 30. Although only the under-cut coupling between the pump body 10 and the pump lower body 30 is shown in accompanying drawings, the present invention is not limited thereto.

(51) The connection piece 13 is formed therein with an elastic member mounting groove 17 so that the elastic member 60 may be securely mounted in the elastic member mounting groove 17.

(52) The pump main body 10 is formed of synthetic resin, and preferably formed of polyethylene (PE).

(53) The pump upper body 20 has the vertical wall 21 fitted into the inner sidewall 11 of the pump body 10 and is moved up and down, the extension protrusion wheel 26 formed at the center thereof with the contents discharge port 22, and a lower portion of the vertical wall 21 that is integrally coupled with the extension protrusion wheel 26.

(54) Since the pump upper body 20 is fitted into the inner sidewall 11 of the pump body 10, and the bending protrusion wheel 14 is formed at the upper end of the inner sidewall 11 of the pump body 10, the vertical wall 21 of the pump upper body is fitted into the bending protrusion wheel 14 of the pump body 10 and is moved up and down. Since the inner diameter of the bending protrusion wheel 14 is equal to or less than outer diameter of the vertical wall 21, the pump upper body 20 is moved up and down in the pump body 10 while maintaining the air tightness.

(55) A locking protrusion wheel 27 protrudes from an outer peripheral surface of a lower end of the vertical wall 21. Accordingly, when the pump upper body 20 is moved up in the pump body 10, the bending protrusion wheel 14 of the pump body 10 is locked to the locking protrusion wheel 27 of the pump upper body 20, thereby preventing the pump upper body 20 from being separated from the pump body 10.

(56) An upper extension piece 28 is integrally formed with an upper end of the vertical wall 21 while extending outward of the upper end of the vertical wall 21, so that the elastic member 60 is elastically supported to a bottom surface of the upper extension piece 28. An outer auxiliary wall 29 may be further integrally formed with an outer end of the upper extension piece 28 while extending downward of the outer end of the upper extension piece 28. The outer auxiliary wall 29 prevents the elastic member 90 from deviating from the outside.

(57) Additionally, when the pump upper body 20 is moved down, a lower end of the outer auxiliary wall 29 makes contact with the connection piece 13 of the pump body 10 to control the pump upper body 20 not to be moved down any more.

(58) The extension protrusion wheel 26 is formed therein with a contents discharge port 22. An outer portion of the extension protrusion wheel 26 is closely covered with the valve protrusion wheel 52 of the discharge valve 50, so that the valve protrusion wheel 52 prevents contents from being discharged out through the contents discharge port 22 in ordinary time.

(59) A contents guide rod 26-1, which has a streamline-shaped surface, is formed inside the extension protrusion wheel 26 so that contents may be smoothly moved toward the contents discharge port 22.

(60) Protrusions 24-1 are formed on the side surface of a lower connecting plate 23 of the pump body 20 and an inner surface of the vertical wall 21 to form the passage 24 in the space between protrusions 24-1 so that contents may flow. A locking step 25 protrudes from the upper end of the protrusion 24-1 and is locked with the discharge valve 50.

(61) The pump upper body 20 is formed of synthetic resin, and preferably formed of polyethylene (PE).

(62) The pump lower body 30 is fitted and coupled to the lower side of the pump body 10, and the contents suction port 32 is formed in the center of a blocking plate 31b. An annular projection 33 protrudes from the upper portion of the blocking plate 31 while surrounding the outer side of the contents suction port 32 to increase the degree of adhesion with the suction valve plate 40.

(63) A coupling protrusion wall 35 is formed on an outer peripheral surface of the pump lower body 30 and is fitted between the outer wall 12 of the pump body 10 and the sealing protrusion wheel 15. Additionally, a coupling protrusion wheel 36 protrudes from an outer lateral side of the coupling protrusion wall 35, wherein the coupling protrusion wheel 36 is fitted into the coupling groove 16 of the pump body 10.

(64) A sealing protrusion wheel 34 may be further formed inside the coupling protrusion wall 35 while being spaced apart from the coupling protrusion wall 35 by a predetermined distance. The sealing protrusion wheel 34 of the pump lower body 30 is coupled with the sealing protrusion wheel 15 of the pump body 10 to increase the sealing force.

(65) Although the coupling of the pump lower body 30 has been described as being the under-cut coupling between the coupling protrusion wheel 36 and the coupling groove 16, the present invention is not limited thereto. In other words, the coupling of the pump lower body 30 may include various manners of coupling, such as press-fitting, thermal-fitting, or coupling by adhesive.

(66) The pump lower body 30 is formed of synthetic resin, such as being preferably formed of polyethylene (PE).

(67) The suction valve plate 40 is provided in the form of a plate and is coupled between the pump body 10 and the pump body 10. Several open/close lines 41 are formed in the suction valve plate 40.

(68) The internal space defined by the pump body 10, the pump upper body 20, and the suction valve plate 40 serves as the temporary space TR where contents stay until the contents are discharged after being sucked.

(69) The suction valve plate 40 may include one of ordinary rubber, elastomer, silicon rubber, NBR rubber, or synthetic resin. Among them, NBR rubber is superior in terms of functionality and air tightness.

(70) The open/close line 41 may be a corrugated cutout line, an arc-shaped cutout line, an oblique cutout line, or a linear straight cutout line. The open/close line 41 may take on various shapes as long as the open/close line 41 can be opened and closed by the elasticity of the suction valve plate 40.

(71) The discharge valve 50 is coupled to the upper portion of the pump body 20 and has a valve protrusion wheel 52 that opens and closes the contents discharge port 22 of the pump body 20. A coupling protrusion wheel 54 protrudes out of the valve protrusion wheel 52 for the coupling of the pump upper body 20.

(72) The discharge valve 50 may be directly coupled to the pump body 20 by the coupling protrusion wheel 54 and may be coupled with the pump upper body 20 by a coupling assisting member 70.

(73) The coupling assisting member 70 is fitted to the outside of the coupling protrusion wheel 54 of the discharge valve 50 and locked to a locking step 25 of the pump upper body 20.

(74) To this end, the coupling assisting member 70 has a coupling protrusion wheel 71 that protrudes inwardly for the coupling with the discharge valve 50, and a coupling groove 55 is formed in an outer portion of the coupling protrusion wheel 54 of the discharge valve 50, so that the coupling protrusion wheel 71 of the coupling assisting member 70 is coupled to the coupling groove of the discharge valve 50.

(75) A locking protrusion 72 protrudes from the outer peripheral surface of the coupling assisting member 70 to be undercut-coupled with the locking protrusion 25 of the pump upper body 20. According to the embodiment of the present invention, the coupling assisting member 70 has been described as being undercut-coupled to the pump upper body 20, but the present invention is not limited thereto.

(76) When the discharge valve 50, to which the coupling assisting member 70 is coupled, is coupled to the pump upper body 20, the bottom surface of the coupling wheel 54 of the discharge valve 50 makes contact with the protrusions of the pump upper body 20, which is horizontally located. In addition, the outer surface of the coupling assisting member 70 makes contact with the protrusion 24-1 of the pump upper body 20, which is vertically located. In this case, the passage 24 is formed to serve as a space where the contents flow between the protrusion 24-1 and an adjacent protrusion 24-1.

(77) The discharge valve 50 may include one of ordinary rubber, elastomer, silicon rubber, NBR rubber, or synthetic resin. Among them, NBR rubber exhibits excellent characteristics in terms of functionality and air tightness.

(78) The elastic member 60 is located between the pump body 10 and the pump upper body 20 to elastically support the pump upper body 20.

(79) The elastic member 60 may include one of a synthetic resin material, elastomer, a rubber material, or a metal material.

(80) Hereinafter, the assembling method of the discharge pump 600 applied to the foundation container according to the present invention having the above configuration will be described.

(81) The suction valve plate 40 and the pump body 10 are assembled under the pump body 10. In detail, after bringing the edge of the suction valve plate 40 into close contact with the lower end of the inner sidewall 11 of the pump body 10, the coupling protrusion wall 35 of the pump lower body 30 is interposed between the outer sidewall 12 of the pump body 10 and the sealing protrusion wheel 15 of the pump body 10. At this time, the pump lower body 30 is assembled with the pump body 10 while being pressed against the pump body 10 so that the coupling wheel 36 of the pump lower body 30 is coupled with the coupling groove 16 of the pump body 10. In this case, the sealing protrusion wheel 34 of the pump lower body 30 makes close contact with the sealing protrusion wheel 15 of the pump body 10 while being offset from the sealing protrusion wheel 15 of the pump body 10 to increase the sealing force.

(82) When the pump body 10 is assembled with the suction valve plate 40 and the pump lower body 30 in the same manner, the edge of the suction valve plate 40 is pressed and fixed between the lower end of the inner sidewall 11 of the pump body 10 and the top surface of the pump lower body 30. The central portion of the suction valve plate 40 makes close contact with an annular protrusion part 33 of the pump lower body 30 to maintain air tightness.

(83) Next, after the elastic member 60 is placed in the elastic member mounting groove 17 formed in the upper portion of the connection piece 13, the pump upper body 20 is fitted into the pump body 10. In this case, the pump upper body 20 is press-fitted into the pump body 10 so that the vertical wall 21 of the pump upper body 20 is inserted into the bending protrusion wheel 14 of the pump body 10.

(84) In this case, the locking protrusion wheel 27 formed on the outer peripheral surface of the lower end of the vertical wall 21 in the pump upper body 20 is inserted into the bending protrusion wheel 14 of the pump body 10 while pressing the bending protrusion wheel 14 of the pump body 10 outward. Once the vertical wall 21 of the pump upper body 20 is inserted into the bending protrusion wheel 14 of the pump body 10, the locking protrusion wheel 27 of the pump upper body 20 is locked to the bending protrusion wheel 14 of the pump body 10, thereby preventing the pump upper body 20 from being the pump body 10.

(85) When the pump upper body 20 is assembled with the pump body 10 as described above, the elastic member 60 is elastically supported between the pump upper body 20 and the pump body 10, and is not exposed out by the outer auxiliary wall 29 of the pump upper body 20 and the outer sidewall 12 of the pump body 10.

(86) Subsequently, the discharge valve 50 is assembled with the upper portion of the pump upper body 20. According to the present invention, description has been made in that the discharge valve 50 is assembled with the pump upper body 20 using the coupling assisting member 70.

(87) Since the coupling assisting member 70 has a ring shape, the coupling assisting member 70 is fitted around the coupling protrusion wheel 54. The discharge valve 50 is formed of a rubber material exhibiting excellent elasticity, and a space 53 is formed inside the coupling protrusion wheel 54. Accordingly, the coupling protrusion wheel 54 is pressed inward and deformed while the coupling assisting member 70 is fitted around the coupling protrusion wheel 54 of the discharge valve 50. In this case, the coupling protrusion wheel 71 of the coupling assisting member 70 is fitted into the coupling groove 55 of the discharge valve 50.

(88) Then, the discharge valve 50, already fitted into the coupling assisting member 70, is press-fitted into the upper portion of the pump upper body 20 in such a manner that the locking step 72 of the coupling assisting member 70 passes the locking step 25 formed on the protrusion 24-1 of the pump upper body 20.

(89) In this case, since the valve protrusion wheel 52 of the discharge valve 50 is covered on the extension protrusion wheel 26 of the pump upper body 20 to make close contact with the extension protrusion wheel 26, the valve protrusion wheel 52 seals the contents discharge port 22 formed in the extension protrusion wheel 26.

(90) In addition, the upper outer peripheral surface of the discharge valve 50 makes close contact with the top surface of the extension protrusion wheel 26 of the pump upper body 20. When the sealing protrusion wheel 56 is further formed on the upper outer peripheral surface of the discharge valve 50, the sealing protrusion wheel 56 makes close contact with the top surface of the upper extension piece 28 of the pump upper body 20.

(91) The contents diffusion member 700 is coupled to the discharge pump 600, and includes the pump upper body 20 and a diffusion plate 750 extending from the upper extension piece 28 of the pump upper body 20.

(92) The diffusion plate 750 of the contents diffusion member 700 may be formed integrally with the pump upper body 20 of the discharge pump 600. Alternatively, the diffusion plate 750 of the contents diffusion member 700 is formed separately from the pump upper body 20 of the discharge pump 600, and coupled to the pump upper body 20 of the 600 after assembling with the pump upper body 20.

(93) The following description will be made while focusing on the structure that the diffusion plate 750 of the contents diffusion member 700 is formed integrally with the pump upper body 20 of the discharge pump 600 according to the present invention.

(94) The contents diffusion member 700 discharges contents through the contents discharge port 22 of the pump upper body 20.

(95) According to the first embodiment of the present invention, the diffusion plate 750 extends from the upper extension piece 2B of the pump upper body 20, and includes a protrusion 751, a recess 752, and a coupling protrusion 753.

(96) The protrusion 751 and the recess 752 have circular shapes based on the pump upper body 20. As shown in FIGS. 11 to 13, the protrusion 751 and the recess 752 are repeatedly formed.

(97) The coupling protrusion 753 protrudes downwardly from a point where the protrusion 751 and the recess 752 are terminated, and is fitted into the coupling groove 353 formed in the upper end of the inner container blocking plate 350, thereby preventing the diffusion plate 750 from being moved.

(98) Contents discharged through the contents discharge port 22 of the pump upper body 20 are placed in the recess 752 of the protrusion 751 and the recess 752, which are repeatedly formed around the pump upper body 20, and impregnated in the impregnation member 800.

(99) According to the second embodiment, as shown in FIG. 14, the diffusion plate 750 extends from the upper expansion piece 28 of the pump upper body 20 and is formed therein with a diffusion passage 755 through which the contents may be diffused.

(100) The coupling protrusion 753 protrudes downward of the edge of the diffusion plate 750, and is fitted into the coupling groove 353 formed in the upper end of the inner container blocking plate 350, thereby preventing the diffusion plate 750 from being moved.

(101) Contents discharged through the contents discharge port 22 of the pump upper body 20 widely flow out through the diffusion passage 755 in a contents passage plate 754 and is impregnated into the impregnation member 800.

(102) The impregnation member 800 is coupled to an upper portion of the contents diffusion member 700 and is uniformly impregnated with the contents as the contents are spread around by the protrusion 751 and the recess 752 formed in the diffusion plate 750 of the contents diffusion member 700.

(103) The impregnation member 800 is an open cell type foam, and the gel-phase contents are not separated from the impregnation member 800 by the surface tension of the foam.

(104) The impregnation member 800 may be formed of at least one selected from the group consisting of butadiene rubber (BR), styrene butadiene rubber (SBR), natural rubber (NR), wet urethane, dry urethane, polyether, polyester, polyvinyl chloride, polyethylene, ethylene vinyl acetate (EVA), latex, silicon, styrene isoprene styrene (SIS), styrene ethylene butylene styrene (SEBS), polyvinyl alcohol (PVA), silicone elastomer, nitrile rubber, butyl rubber and neoprene.

(105) As shown in FIG. 6, the fixture 330 is fixedly fitted between the outer wall 301 and the inner wall 302 of the inner container body 300, thereby preventing the deviation of the inner container blocking plate 350, the contents diffusion member 700, and the impregnation member 800.

(106) A locking annular protrusion 331 formed at an upper end of the fixture 330 presses an upper end of the impregnation member 800 so that the impregnation member 800 is not moved.

(107) A hinge bracket 401 is formed at one side of the inner container lid 400, and a hinge bracket coupling unit 411 is formed inside the hinge bracket 401. The inner container lid 400, which seals the inner container body 300, is provided therein with the puff built-in space 410 to store the puff 900 which is a cosmetics tool.

(108) The hinge bracket 401 is coupled to the hinge protrusion 421 of the puff cover 420 to cover the inner container lid 400.

(109) The hinge bracket coupling unit 411 is coupled with the hinge bracket 311 of the inner container body 300, and the inner container body 300 is coupled to the inner container lid 400 to seal the inner container body 300.

(110) The puff 900 is located in the puff built-in space 410 of the contents container lid 400 and is formed of cotton, fabric, foamed NBR, ruby cell, polyester or the like so that the user does not have a sense of heterogeneity when the puff 900 comes into contact with the skin, or the puff 900 may be formed of sponge having flexibility or soft urethane foam.

(111) The hinge protrusion 421 is formed at one side of the puff cover 420, and hinged with the inner container cap 400.

(112) The hinge protrusion 421 is fitted into the hinge bracket 401 of the inner container lid 420 and fixedly hinged with the hinge bracket 401.

(113) Hereinafter, the assembling method and the use state of the foundation container including the contents diffusion member and the discharge pump having the shorter stroke according to the embodiment of the present invention will be described with reference to accompanying drawing.

(114) In order to assemble the foundation container including the contents diffusion member and the discharge pump having the shorter stroke, the inner container body 300 (having an auxiliary container 370) is fitted into a lower end of the outer container body 100 and contents are injected into the auxiliary container 370 as shown in FIG. 6.

(115) According to another embodiment of the present invention, as shown in FIG. 10, after the inner container body 300 having a plate 371 is fitted into the lower end of the outer container body 100, the contents are injected into the auxiliary container 370.

(116) Then, the inner container blocking plate 350 is fixedly mounted on the inner container body 300 to seal the inner container body 300. The sealing ring may be further coupled to the outer peripheral surface of the inner container blocking plate 350 to enhance sealing force.

(117) Thereafter, after forming the discharge pump 600 at the center of the inner container blocking plate 350, the contents diffusion member 700 is coupled to the upper portion of the pump upper body 20 of the discharge pump 600. Then, the impregnation member 800 is coupled to the upper portion of the contents diffusion member 700.

(118) In order to prevent the deviation of the inner container blocking plate 350, the contents diffusion member 700, the impregnation member 800, and the fixture 330 are mounted; the inner container lid 400 is hinged with the inner container body 300; and the puff 900 is provided in the puff built-in space 410 of the inner container cap 400.

(119) Then, the puff cover 410 is hinged with the inner container cap 400, thereby completing the assembly of the foundation container including the contents diffusion member and the discharge pump having the shorter stroke according to the embodiment.

(120) In order to use contents contained in the foundation container including the contents diffusion member and the discharge pump having the shorter stroke, the impregnation member 800 is pressed using the puff 900. As the impregnation member 800 is pressed, and if the contents diffusion member 700 and the discharge pump 600 are moved down, the pump upper body 20 of the discharge pump 600 is moved down such that the volume of the temporary storage TR is reduced while the pressure is increased in the temporary storage TR. Accordingly, the suction valve plate 40 closes the contents suction port 32, and the valve protrusion wheel 52, making close contact with the contents discharge port 22, is spread by the pressure of contents discharging from the temporary storage TR while the contents pass through the spread gap between the contents discharge port 22 and the valve protrusion wheel 52.

(121) Thereafter, after the contents pass through the passage 24 (a gap between the pump upper body 20) and the discharge valve 50, discharge pressure acts on the upper periphery of the discharge valve 50 to spread the gap between the upper surface of the pump upper body 20 and the upper peripheral edge of the discharge valve 50 so that the contents are discharged through the gap.

(122) In this case, the sealing protrusion 56 of the upper peripheral part of the discharge valve 50 is moved up while the contents are discharged through the gap formed when the sealing protrusion is moved up.

(123) If the pressure is removed, the pump upper body 20 is moved up due to the restoring force of the elastic member 60 and the temporary storage TR in the pump body 10 is enlarged, which generates vacuum pressure. Due to the vacuum pressure, the space between the valve protrusion wheel 52 of the discharge valve 50 and the contents discharge port 22 is closed, and the central portion of the suction valve plate 40 is moved up. Accordingly, the boundary of an open/close line 41 is opened, which allows the contents contained in the auxiliary container 370 to move to the temporary storage TR through the space between the suction valve plate 40 and the contents intake port 32.

(124) Vacuum pressure is also generated as the contents in the auxiliary container 370 are moved into the temporary storage TR of the discharge pump 600 such that the auxiliary container 370 is separated from the inner container body 300 and shrunken as shown in FIG. 9.

(125) According to another embodiment, as shown in FIG. 10, when the plate 371 is mounted in the inner container body 300 instead of the auxiliary container 370 and when the contents are moved into the temporary storage TR of the discharge pump 600 from the inner container body 300, the vacuum pressure is generated and the plate 371 is moved such that the contents are pushed towards the contents suction port 32 of the discharge pump 600.

(126) The contents, which have passed through the contents suction port 32, are moved into the temporary storage TR through the spread gap of the open/close line 41 of the suction valve plate 40. As the contents move, the vacuum pressure disappears from the temporary storage TR. In this case, the open/close line 41, which is open, is recovered to its original state and closed due to the self-elastic force of the suction valve plate 40, which leads the suction valve plate 40 to close the contents suction port 32.

(127) The contents discharged by a discharge action of the discharge pump 600 are moved to the diffusion plate 750 of the contents diffusion member 700. The contents, which are moved into the protrusion 751 and the recess 752 of the diffusion plate 750, are uniformly impregnated into the entire portion of the impregnation member 800. Thereafter, a user may apply the contents, which are impregnated into the impregnation member 800, on the puff 900.

(128) Although a preferred embodiment of the present invention has been described for illustrative purposes in order to replicate the foundation container including the contents diffusion member and the discharge pump having the shorter stroke, the present invention is not limited to the embodiment, and 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.
