(V) Specific implementation methods:

[0024] Below, an embodiment of the present invention will be described in detail. However, this is only exemplary and does not limit the present invention, which will be defined by the scope of the claims. The embodiments described below can be modified in various forms without departing from the concept and scope of the present invention. The same or similar parts are represented by the same drawing reference numerals in the drawings as much as possible.

[0025] The terms used in the description of the present embodiment are only to refer to specific embodiments and do not limit the present invention. The singular form used herein includes the plural form unless the context clearly indicates otherwise. "Including" used in this specification means to specify specific features, regions, integers, steps, operations, elements and / or components, and does not exclude the existence or addition of other specific features, regions, integers, steps, operations, elements, components and / or groups.

[0026] In the description of this embodiment, expressions such as up, down, front, back, first, second, one side, the other side, etc. are only used to indicate relative positions or directions, and sequences, and are not to be construed as being limited to their dictionary meanings.

[0027] Figure 1 The overall structure of the cosmetic container of this embodiment is shown. Figure 2 The upper structure of the cosmetic container including the pumping device is shown. In addition, Figure 3-1 , Figure 3-2 and Figure 4-1 , Figure 4-2 The various components of the pumping unit are shown.

[0028] In the following description, "axial direction" refers to the direction through the central axis. Figure 1 The middle part refers to the y-axis direction. When the cosmetic container is placed on the base, the upper part along the y-axis direction is called the upper part or the upper side, and the opposite direction is called the lower part or the lower side.

[0029] like Figure 1 As shown, the cosmetic container of this embodiment includes a container body 100 for containing contents, and a pumping device 200 combined with an upper opening portion 110 of the container body 100 and acting through its own elasticity, and the pumping device 200 discharges the contents in the container body 100 through pumping action. It also includes a liquid discharge head 300 connected to the pumping device 200 and applying discharge pressure, and a content discharge port 320 connected to the pumping device 200 is provided on one side of the liquid discharge head 300.

[0030] The container body 100 is a tubular structure having an internal space, and the internal space can be filled with various types of cosmetics (hereinafter referred to as "contents"). The contents can be not only cosmetics, but also external medicines such as disinfectants or household products such as detergents. The shape of the container body 100 can be various.

[0031] The container body 100 is formed with an opening portion 110 at its upper end. The upper opening portion 110 of the container body 100 is connected to the pumping device 200. Therefore, the content inside the container body 100 is discharged from the opening portion 110 through the pumping device 200 and discharged to the outside through the liquid discharge head 300.

[0032] The upper cover 130 shown in the figure is used to cover the liquid dispensing head 300 to provide protection.

[0033] The cosmetic container of this embodiment is also equipped with a piston member 120 inside the container body 100. The piston member 120 fits tightly against the inner wall of the container body 100 and can be slidably installed along the inner wall. When the pumping device 200 discharges the contents of the container body 100, the piston member 120 rises toward the opening portion. At this time, external air can flow in through the hole formed at the bottom of the container body 100, so that the piston member 120 can rise smoothly and maintain the shape of the container body 100. As the amount of contents discharged increases, the piston member 120 rises toward the opening portion 110 of the container body 100, thereby maintaining a certain pressure inside the container body 100. In addition, the contents of the container body 100 can be pushed toward the opening portion by the piston member 120 so that they can be smoothly discharged through the opening portion later.

[0034] The pumping device 200 is detachably coupled to the upper opening portion 110 of the container body 100. For example, a thread is formed on the outer circumferential surface of the upper opening portion of the container body 100, and the pumping device 200 can be tightly mounted on the upper end of the opening portion 110 through a threaded connection of a separate fastening member 170. The coupling structure between the pumping device 200 and the container body 100 can be in various forms.

[0035] The liquid discharge head 300 is combined with the pumping device 200, and drives the pumping device 200 by applying pressure to the pumping device 200. In this embodiment, the liquid discharge head 300 drives the pumping device 200 by pressing up and down.

[0036] The liquid outlet head 300 of this embodiment is a cylindrical member that can be inserted into the upper inner side of the fastening component 170 and can be installed to move up and down. The top surface of the liquid outlet head 300 can be a concave design. The central part of the liquid outlet head 300 can be arranged to form a plurality of content outlets 320. The content outlet 320 is connected to the pumping device 200, and the content is discharged to the outside through the outlet 320.

[0037] Therefore, when the user presses the liquid discharge head 300, the liquid discharge head 300 applies pressure to the pumping device 200, thereby driving the pumping device 200. Therefore, the content discharged by the pumping device 200 is discharged through the content discharge port 320 of the liquid discharge head 300. The shape of the liquid discharge head 300 can be various.

[0038] The pumping device 200 is combined with the upper opening portion 110 of the container body 100 , and delivers the content in the container body 100 to the liquid discharge head 300 according to the operation of the liquid discharge head 300 .

[0039] The pumping device 200 can change the internal pressure through the pumping action of its own elasticity, thereby discharging the content of the container body 100.

[0040] refer to Figure 2 to Figure 5-1 , Figure 5-2 , the various components of the pumping device will be explained.

[0041] The pumping device 200 is tightly mounted on the opening portion 110 of the container body 100, and includes: a shell 210 having a hole 211 formed in the central portion thereof which is connected to the interior of the container body 100, a pumping component 220 which is combined with the shell 210 and connected to the hole 211 of the shell, forms a content accommodating space inside, and is elastically compressed or expanded along the axial direction to transport the content unidirectionally along the axial direction, a channel II271 which is combined with the pumping component 220 and forms an internal content movement channel, a nozzle component 270 which connects the pumping component 220 and the content discharge port 320 of the liquid discharge head 300, and selectively opens or closes the channel between the internal channel II271 and the internal space of the pumping component 220 according to the operation of the liquid discharge head 300, and a one-way valve 233 which is mounted on the hole 211 of the shell 210 and selectively opens or closes the hole 211 according to the movement of the pumping component 220 to allow the content to flow from the container body 100 into the interior of the pumping component 220 in a unidirectional manner.

[0042] Therefore, since the one-way valve 233 is separately provided and installed on the housing 210, the installation of the one-way valve 233 becomes easy, and the structure of the pumping member 220 can be further simplified.

[0043] The housing 210 is coupled to the container body 100 and supports various components of the pumping device 200 to enable operation.

[0044] The housing 210 is a circular plate-like structure, and a through hole 211 is formed in the center portion thereof. The housing 210 is communicated with the container body 100 through the hole 211. The housing 210 is tightly mounted on the opening portion 110 of the container body 100. A sealing gasket 180 may be further mounted between the upper end of the housing 210 and the opening portion 110 of the container body 100 to maintain sealing.

[0045] A pumping member 220 is mounted on an upper end of the housing 210 .

[0046] like Figure 2 and Figure 3-1 , Figure 3-2 As shown, in order to allow the pumping component 220 to be installed, the housing 210 is formed with an outer wall 212 and an inner wall 213 protruding upward around the hole 211 thereof.

[0047] The outer wall 212 supports the outer surface of the flange 232 formed at the lower end of the pumping member 220, and the inner wall 213 is spaced apart from the outer wall 212 and supports the inner surface of the flange 232. The space between the outer wall 212 and the inner wall 213 forms a groove 214 into which the flange 232 is inserted. Therefore, the flange 232 of the pumping member 220 is tightly inserted into the groove 214 of the housing 210 for installation.

[0048] A limiting flange 215 is formed on the inner surface of the outer wall 212 to prevent the flange 232 of the pumping member 220 from being separated from the groove 214 .

[0049] In addition, the housing 210 further includes a valve mounting portion 216 formed to protrude upward along the periphery of the hole, for inserting and mounting the one-way valve 233 .

[0050] The size of the valve installation part 216 corresponds to the one-way valve 233, and the one-way valve 233 can be inserted into and tightly installed in the valve installation part 216. A limiting flange 215 is formed on the inner surface of the valve installation part 216 to prevent the one-way valve 233 from being separated.

[0051] The structure of the pumping member 220 can be further simplified by providing the valve mounting portion 216 on the housing 210 and installing the check valve 233. Therefore, the pumping member 220 can have a simple structure with only the flange 232 formed at the lower end without the check valve.

[0052] The one-way valve 233 is detachably mounted on the valve mounting portion 216 of the housing 210 , so when necessary, only the one-way valve 233 may be installed or replaced.

[0053] The upper end of the pumping member 220 is provided with a nozzle member 270 , and the lower end is installed on the housing 210 and connected to the hole 211 of the housing. The pumping member 220 selectively connects with the inner space between the groove 214 to deliver the contents to the nozzle member 270 .

[0054] like Figure 2 and Figure 4-1 , Figure 4-2As shown, the pumping component 220 of this embodiment forms an internal space between the housing 210 and the housing 210, and is compressed and elastically restored under the action of external force to change the pressure of the internal space. The pumping component 220 includes a pressure component 1231, which extends from below the groove 214 of the housing 210 to form a flange 232 tightly combined with the groove 214 of the housing 210, an insert 241 formed on the upper side of the pressure component 1231 and combined with the nozzle component 270 and installed at the lower end of the liquid outlet head 300, a blocking component 243 formed on the lower inner side of the insert 241 and constituting a content discharge channel and elastically changing the inner diameter to be tightly combined with the nozzle component to block the pressure component and the internal channel of the nozzle component, and a flexible component 244 formed on the insert 241 and elastically expanding or contracting according to the operation of the liquid outlet head 300 to open or close the space between the blocking component 243 and the nozzle component 270.

[0055] The flange 232 formed at the lower end of the pumping member 220 extends axially downward to form a ring. The thickness of the flange 232 corresponds to the distance between the inner wall 213 and the outer wall 212 of the housing 210, and can be tightly fitted in the groove 214 between the inner wall 213 and the outer wall 212 of the housing 210.

[0056] In addition, the flange 232 can be tightly coupled to the groove 214 of the housing to maintain sealing. A protrusion 234 is formed on the inner surface of the flange 232, and a recess 235 matching the protrusion 234 is formed on the inner side of the inner wall 213 contacting the flange 232.

[0057] Therefore, when the flange 232 is inserted into the groove portion 214 and coupled, the protrusion 234 will match with the recess 235, thereby tightly fitting by pressure, thereby preventing the contents from leaking from the coupled portion.

[0058] As described above, the pumping member 220 has a simple structure, the lower end of which is open, and the flange 232 can be inserted into the groove portion 214 of the housing 210 and combined with the housing 210. The area surrounded by the pumping member 220 and the housing 210 forms the inner space of the pressure member 1231.

[0059] The pumping component 220 changes the pressure of the internal space through its own compression or elastic recovery, thereby transporting the contents in one direction.

[0060] The so-called compression means that the original state is compressed under the action of external force, and the volume is reduced. The so-called expansion means that the compressed state is restored to the original state, and the volume is increased. In this way, the pressure part and the flexible part are constructed in an elastically deformable form, and when the external force is removed, they can be restored to the original state by their own elastic restoring force.

[0061] The pumping member 220 may be made of elastic material such as rubber, silicone or synthetic resin.

[0062] The pressure component 1231 changes the pressure of the internal space by compressing and expanding itself according to the operation of the liquid outlet head 300. In this embodiment, the pressure component 1231 is designed to be elastically deformed according to the operation of the liquid outlet head 300 and increase in length along the axial direction.

[0063] like Figure 4-1 , Figure 4-2 As shown, the pressure component 1231 of this embodiment can be formed relatively thin in order to be elastically deformable, and can be designed to be an inclined surface shape with a gradually decreasing inner diameter along the axial direction. In this way, injection molding is easier.

[0064] A flange 232 is integrally formed at the lower portion of the pressure member 1231.

[0065] The flange 232 is formed to protrude axially downward from the outer peripheral surface of the pressure member 1231. The flange 232 is a portion coupled to the housing 210 and is installed in the groove 214 of the housing 210.

[0066] The pumping part 220 is combined with the housing 210 through the flange 232, and the internal space of the pressure part 1231 is formed, and this space is directly connected to the one-way valve 233 below. The content flowing in from the one-way valve 233 is accommodated in the internal space formed by the pressure part 1231.

[0067] The pressure component 1231 compresses or expands the internal space through elastic deformation of the inclined surface portion, thereby changing the pressure and achieving a pumping effect. When the pressure component 1231 is compressed, a discharge pressure is applied to the contents. When the external force is removed, the elastic restoring force thereof returns to the original state, thereby applying a suction pressure to the contents of the container body 100.

[0068] When the external force applied to the liquid outlet head 300 causes the force on the pumping component 220 to be transmitted to the pressure component 1231, the pressure component 1231 elastically deforms and compresses the internal space. As the pressure component 1231 continues to be compressed, the pressure in its internal space increases. When the pressure in the internal space is relatively greater than that of the container body 100, the one-way valve 233 fits tightly on the hole 211 and remains closed. According to the compression of the pressure component 1231, the pressurized contents are finally discharged to the liquid outlet head 300 through the nozzle component 270.

[0069] When the external force applied to the pumping part 220 is removed, the pressure part 1231 expands and returns to its original shape by its own elastic force. When the internal space of the pressure part 1231 expands, the internal pressure becomes relatively low relative to the container body 100. Therefore, the gap between the one-way valve 233 and the hole 211 increases and opens, and the contents in the container body 100 flow back into the internal space of the pressure part 1231 and are filled.

[0070] In addition, the pumping component 220 of the present embodiment includes a disc-shaped component 236 at the upper portion of the pressure component 1231, and the disc-shaped component 236 is formed to protrude outward from the upper periphery of the pressure component 1231.

[0071] The disk-shaped component 236 can prevent the pressure component 1231 from being rapidly compressed or excessively deformed, thereby enabling the pressure component 1231 to operate smoothly.

[0072] like Figure 4-1 , Figure 4-2 As shown, the disc-shaped component 236 is formed extending outward along the upper end circumference of the pressure component 1231. The disc-shaped component 236 is a circular plate structure extending in the horizontal direction and is formed integrally with the pumping component 220. The disc-shaped component 236 is located above the pressure component 1231 and contacts the pressure component 1231 when the pumping component 220 is compressed.

[0073] When the pumping member 220 is compressed, the pressure member 1231 is elastically deformed and compressed, and the disc member 236 located above the pressure member 1231 descends and contacts the deformed pressure member 1231.

[0074] Since the disc-shaped component 236 contacts the outer side of the pressure component 1231, the compression of the pressure component 1231 is limited. That is, when the pumping component 220 is compressed downward, the pressure concentrated on the upper end of the pressure component 1231 gradually causes the pressure component 1231 to deform from the upper end. As the pressure component 1231 deforms, the disc-shaped component 236 contacts the pressure component 1231. When the disc-shaped component 236 contacts the pressure component 1231, the pressure applied to the pressure component 1231 is dispersed through the wide surface of the disc-shaped component 236. In this way, the disc-shaped component 236 acts as a blocking structure that prevents the upper end of the pressure component 1231 from being pressed down and deforming downward. Therefore, the pressure component 1231 can be prevented from deforming sharply.

[0075] In addition, if the upper end of the pressure component I231 is continuously compressed, the pressure component I231 may flip over and deform beyond the elastic recovery limit position. In this case, the pressure component I231 may not be able to return to its original state. The disc-shaped component 236 can prevent the upper end of the pressure component I231 from being further compressed downward beyond the elastic recovery limit position by contacting the pressure component I231. Therefore, the disc-shaped component 236 can prevent the bouncing action of the pressure component I231 when it is sharply compressed, so that the pumping component 220 runs more smoothly and improves the user experience when pressing the liquid discharge head 300. In addition, since the pressure component I231 can smoothly return to its original state after compression, operational failures such as the liquid discharge head being pressed can be prevented.

[0076] The one-way valve 233 contacts or separates from the hole 211 of the housing 210 to open or close according to the pressure inside the pumping component 220. In this embodiment, the one-way valve 233 may include a valve plate 238, which is connected by a plurality of ribs 239, and the ribs 239 can be elastically expanded and contracted, so that the valve plate 238 moves to open or close the hole 211.

[0077] The one-way valve 233 is opened or closed according to the pressure change inside the pumping part 220, thereby allowing the content to be transmitted from the container body 100 to the pumping part 220 in one direction only. That is, when the pressure inside the pumping part 220 is relatively low, the valve plate 238 of the one-way valve 233 is opened, allowing the content inside the container body 100 to flow into the pumping part 220 through the hole 211 and the one-way valve 233. On the contrary, when the pressure inside the pumping part 220 is relatively high, due to the pressure applied to the one-way valve 233, the valve plate 238 is pressed against the hole 211 and blocks the hole 211, thereby preventing the content inside the pumping part 220 from moving to the container body 100.

[0078] The insert 241 is formed at the upper end of the pumping member 220 and is plug-in-combined with the nozzle member 270. The insert 241 can be installed in close combination with the nozzle member 270. The insert 241 selectively communicates with the internal channel II271 of the nozzle member 270.

[0079] The insert 241 is a cylindrical tubular structure, which is formed to extend in the axial direction at the upper end of the pumping member 220. The nozzle member 270 can be inserted and installed inside through the open upper end of the insert 241. The inner surface of the insert 241 and the outer surface of the nozzle member 270 can be respectively formed with flange portions that mesh with each other, so that they can be tightly combined.

[0080] The insert 241 is combined with the liquid discharge head 300. The lower end of the liquid discharge head 300 protrudes to form a circular bracket 310 of a size corresponding to the insert 241. The insert 241 can be inserted into the circular bracket 310 formed at the lower end of the liquid discharge head 300 and installed in a tightly combined manner. For example, flange portions can be formed between the outer surface of the insert 241 and the inner surface of the bracket 310, respectively, so as to engage and fix with each other.

[0081] A blocking member 243 is formed inside the insert 241 .

[0082] The blocking component 243 is formed by extending along the central axis of the insert 241 to form a content delivery channel 1242. The lower end of the blocking component 243 is formed with a free end, which can be elastically opened to the outside, thereby forming a structure that can expand the inner diameter. The blocking component 243 is tightly matched with the insertion portion 274 of the nozzle component 270 passing through the channel 1242 to selectively block the space between the pressure component 1231 and the internal channel of the nozzle component 270.

[0083] The blocking member 243 can be elastically closely matched with the inserting portion 274 of the nozzle member 270. In this way, the closed state between the pumping member 220 and the nozzle member 270 can be maintained.

[0084] The elastic deformation of the flexible member 244 causes the blocking member 243 and the nozzle member 270 to be opened or closed.

[0085] The flexible member 244 of this embodiment is integrally formed at the lower portion of the insert 241 and is elastically deformed according to the operation of the liquid discharge head 300 to increase its length in the axial direction.

[0086] The flexible component 244 changes the pressure of the internal space through its own elastic compression and expansion. In order to be able to deform elastically, the flexible component 244 of this embodiment can be formed relatively thin, and can be designed into a slope shape with a gradually decreasing inner diameter along the axial direction.

[0087] The inner space formed by the flexible member 244 communicates with the channel 1242 of the blocking member 243 located at the center, and the channel 1242 communicates with the pressure member 1231 . The content of the pressure member 1231 moves into the inner space formed by the flexible member 244 .

[0088] The flexible member 244 moves the blocking member 243 upward through elastic deformation of the inclined surface portion, and compresses or expands the inner space to change the pressure, thereby opening or closing the space between the blocking member 243 and the nozzle member 270 .

[0089] When the external force applied to the liquid discharge head 300 causes the flexible member 244 to be elastically compressed, the blocking member 243 moves upward. In this way, the blocking member 243 moves upward relative to the fixed position insertion portion 274, resulting in a gap between the protruding portion 276 formed by the insertion portion 274 and the blocking member 243. In addition, since the internal pressure increases due to the compression of the flexible member 244, the blocking member 243 elastically expands its outer diameter outward, thereby expanding the gap, so that the contents can move from the inside of the flexible member 241 to the channel II271 of the nozzle member through the gap.

[0090] When the external force applied to the pumping member 220 is removed, the flexible member 244 returns to its original state by its own elastic restoring force, and the blocking member 243 moves downward to its original position and is closely matched with the protruding portion 276 formed by the inserting portion 274 of the nozzle member 270. In this way, the insertion portion 274 and the blocking member 243 are closed, blocking the discharge of the contents.

[0091] When the flexible component 244 returns to its original state, the pressure component 1231 expands and deforms by its own elastic restoring force and returns to its original state. When the pressure component 1231 expands and deforms, negative pressure is formed in the internal space. Since the blocking component 243 and the nozzle component 270 are in a closed state, the negative pressure of the pressure component 1231 causes the contents of the container body 100 to flow into the internal space of the pressure component 1231 through the one-way valve 233. Through the sequential operation of the pressure component 1231 and the flexible component 244, the pumping effect of the contents can be smoothly achieved.

[0092] The nozzle component 270 includes a nozzle body 272 that forms an internal content delivery channel II271, and an insertion portion 274 that tightly fits with the inner side of the upper end of the insert 241 of the pumping component, the lower end of the insertion portion 274 is formed with a slot into which the blocking component 243 of the insert 241 is inserted, the side of the insertion portion 274 is formed with a liquid inlet hole 275 that is connected to the channel II271 and the interior of the insert 241, and a raised portion 276 that protrudes outward from the outer peripheral surface of the lower end of the insertion portion 274 and is tightly combined with the inner surface of the blocking component 243 to block the space between the insert 241 and the flexible component 244.

[0093] The nozzle component 270 is combined with the upper end insert 241 of the pumping component 220 and is placed at the lower end of the liquid discharge head 300. The upper end of the nozzle component 270 is communicated with the content discharge port 320 of the liquid discharge head 300, and the lower end is combined with the pumping component 220. A channel II271 for content movement is formed inside the nozzle component 270. According to the operation of the liquid discharge head 300, when the pumping component 220 is compressed, the channel II271 inside the nozzle component 270 is selectively communicated with the internal space of the pumping component 220.

[0094] The nozzle part 270 is combined with the upper end insert 241 of the pumping part 220 to connect the pumping part 220 and the liquid outlet head 300. A channel II 271 is formed inside the nozzle part 270 to form a moving channel for the contents. The channel II 271 is connected to the content outlet 320 through the inside of the liquid outlet head 300.

[0095] The nozzle part 270 acts on the pumping part 220 to compress the pumping part 220 according to the operating force of the liquid discharge head 300 , and opens or closes the blocking part 243 of the flexible part 244 .

[0096] The nozzle body 272 is formed in a cylindrical shape corresponding to the diameter of the insert 241. The nozzle body 272 can be tightly inserted into the insert 241 and installed to prevent it from falling outward. For example, flange portions can be formed on the inner surface of the insert 241 and the outer surface of the nozzle body 272 to engage and fix with each other.

[0097] Since the inserting member 241 of the pumping member 220 is combined with the lower end of the liquid discharge head 300 , the nozzle body 272 inserted into the inserting member 241 may be installed in close combination with the lower end of the liquid discharge head 300 .

[0098] An inserting portion 274 is formed integrally at the center of the lower end of the nozzle body 272. The inserting portion 274 is inserted into and tightly combined with the blocking member 243 of the insert 241. A channel II271 is formed inside the inserting portion 274.

[0099] A liquid inlet hole 275 may be formed on the side of the inserting portion 274. There may be at least one liquid inlet hole 275, which is formed along the outer circumference of the inserting portion 274 at a certain distance.

[0100] In this way, the contents flowing in from between the blocking member 243 and the insertion portion 274 can move into the internal channel II 271 through the liquid inlet hole 275 .

[0101] A convex portion 276 is formed on the outer peripheral surface of the lower end of the insertion portion 274. The convex portion 276 is larger than the outer diameter of the insertion portion 274 so as to fit tightly with the blocking member 243 and block the gap.

[0102] As described above, when the operation of the liquid discharge head 300 causes the flexible member 244 to be in a compressed state and elastically deformed, the blocking member 243 moves upward relative to the fixed protrusion 276, thereby generating a gap between the protrusion 276 and the blocking member 243. In this way, the contents inside the insert 241 can move into the channel II 271 of the nozzle member through the gap.

[0103] The pumping device 200 of this embodiment may also be equipped with an auxiliary one-way valve 280 inside the nozzle body 272 to selectively block the channel II 271 and discharge the content to the liquid outlet head 300 in a one-way manner.

[0104] The auxiliary check valve 280 contacts or separates from the channel II 271 of the nozzle part 270 to open or close according to the pressure inside the pumping part 220. The auxiliary check valve 280 of this embodiment may have the same structure as the check valve 233. For example, the auxiliary check valve 280 may include a valve plate connected by a plurality of ribs, and the ribs may be elastically retracted so that the valve plate moves to open or close the channel.

[0105] The auxiliary check valve 280 is opened or closed according to the pressure change inside the pumping part 220, thereby allowing only one-way transmission of the contents from the pumping part 220 to the liquid outlet head 300. That is, when the pressure inside the pumping part 220 is relatively high, the valve plate of the auxiliary check valve 280 rises and opens the channel II 271. In this way, the contents of the pumping part can pass through the channel II 271 and be discharged through the content outlet 320 of the liquid outlet head 300. On the contrary, when the pressure inside the pumping part 220 is relatively low, the valve plate of the auxiliary check valve 280 descends and clings to the upper end of the channel II 271, thereby blocking the channel II 271. In this way, the external air from the content outlet 320 of the liquid outlet head 300 will not move to the pumping part 220.

[0106] By further installing an auxiliary one-way valve 280 on the channel II271 of the nozzle component 270, leakage of the contents can be blocked and the inflow of external air can be more effectively prevented.

[0107] on the other hand, Figure 5-1 , Figure 5-2 Another embodiment of a pumping device is shown, Figure 6 A cross-sectional view showing the overall structure of a cosmetic container according to another embodiment

[0108] The embodiment described below is the same as the embodiment described above except that the pressure portion of the pumping member has a different form. For the same components, the same reference numerals will be used and detailed description thereof will be omitted.

[0109] like Figure 5-1 , Figure 5-2As shown, the pumping component 220 according to the present embodiment is formed with an internal space, and the pressure of the internal space is changed by compression and elastic recovery under the action of external force. The pumping component 220 includes: a pressure component II237 that forms the internal space and changes the pressure of the internal space by compression and elastic recovery under the action of external force; a flange 232 that extends downward from the lower peripheral surface of the pressure component II237 and is tightly combined with the groove 214 of the housing 210; an insert 241 formed on the upper side of the pressure component II237 and combined with the nozzle component 270 and installed at the lower end of the liquid discharge head 300; a blocking component 243 formed on the lower inner side of the insert 241 and constituting the content discharge channel and can elastically change the inner diameter to be tightly combined with the nozzle component to block the pressure component and the internal channel of the nozzle component; a flexible component 244 formed on the insert 241 and elastically expands and contracts according to the operation of the liquid discharge head 300 to open or close the space between the blocking component 243 and the nozzle component 270.

[0110] The pressure component II237 can be formed into a pleated shape with a thin thickness to allow compression deformation under external force. In the present embodiment, the pressure component II237 can be formed into a multi-pleated structure formed by continuous bending, similar to an accordion. In this way, the pressure component II237 can be elastically deformed more easily. In addition, the pressure component II237 can be elastically deformed more smoothly, thereby minimizing noise during operation.

[0111] As described above, the exemplary embodiments of the present invention have been shown and described, but there will be various variations and other embodiments implemented by those skilled in the art. These variations and other embodiments will be considered within the scope of the appended claims and are included in the true intent and scope of the present invention.
