Abstract
Description
Technical Field
[0001] This invention relates to cosmetic containers capable of variablely adjusting the discharge volume of their contents. Background Technology
[0002] This device is used to dispense liquid or gel-type contents (cosmetics, shampoo, detergent, etc.) from a container. A pump, acting as a dispensing device, is attached to the top of the container. When the user presses down on the top of the pump, the contents are dispensing through the pump due to the pressure change inside the pump and the opening of the valve. This type of pump prevents the contents from leaking out, thus offering the advantages of preventing spoilage and ensuring hygiene.
[0003] Conventional pumps suffer from inconsistent discharge volumes depending on the level of downward pressure applied. Specifically, high downward pressure and a long travel distance for internal valves result in a large discharge volume, while low pressure and a short travel distance result in a smaller discharge volume. Consequently, conventional pumps cannot precisely adjust the discharge rate.
[0004] Furthermore, containers are being used that allow two different contents to be stored separately in one container and then mixed before use. With such mixing containers, when two different contents are mixed before use, the contents may deteriorate or their performance may decrease during prolonged circulation. Since more than two contents are mixed, they are primarily used when a synergistic effect in functionality is expected.
[0005] Even in the case of a mixed container, the mixing effect can be maximized by keeping the mixing ratio of the two different contents constant. Therefore, even in the case of a mixed container, the ability to adjust the discharge rate of the contents is required.

[0009] The problem to be solved
[0010] Therefore, the present invention is proposed to solve the above-mentioned problems and to provide a cosmetic container that can variably adjust the discharge volume of the contents.
[0011] Other objects of the present invention will become more apparent from the embodiments described below.
[0012] Methods for solving problems
[0013] A cosmetic container according to one aspect of the present invention includes: an outer container for storing contents; a handle rotatably attached to the upper part of the outer container; an adjustment member attached to the upper part of the handle and rotatably integral with the handle and having a downwardly protruding pressure protrusion; and a pump for drawing in and discharging contents stored in the outer container and changing the amount of discharging contents by pressurizing a portion of the contents by the pressure protrusion, wherein the pump discharge rate is adjusted by adjusting the amount of pressure pumped by the pressure protrusion by rotating the adjustment member.
[0014] The cosmetic container of the present invention may have one or more of the following embodiments. For example, the adjusting member may have a guide hole in which the pump can move, and the pressurizing protrusion may be continuously formed on the lower part of the inner circumferential surface of the guide hole.
[0015] Two guide holes can be formed symmetrically to each other, and pressure protrusions can be formed symmetrically from left to right.
[0016] The guide hole and the line passing through the rotation center of the adjusting component can intersect at two points, and the pressure protrusions corresponding to the two points can have the same length.
[0017] The length of the pressure protrusion is maximized at one end of the guide hole, while no pressure protrusion is formed at the other end of the guide hole.
[0018] A shoulder is attached to the upper part of the outer container, and a handle is rotatably attached to the upper part of the shoulder. A nozzle is attached to the upper part of the adjustment component, and the nozzle is connected to the pump to provide a channel for discharging the contents.
[0019] The pump has a pressure flange and a valve flange. The pressure flange can be pressurized downward by the pressure protrusion, and the valve flange can be locked onto the guide of the regulating component.
[0020] A shoulder groove can be formed on the outer peripheral surface of the shoulder, and an indicator protrusion that inserts into the shoulder groove can be formed on the inner peripheral surface of the handle. By forming multiple shoulder grooves, the amount discharged by the pump can be indicated.
[0021] It includes an inner container that can be detachably attached to an outer container, the inner container being filled with contents, and its open inlet being connected to a pump when the inner container is attached to the outer container.
[0022] The internal container is fitted with a suction pipe support, and the pump can be inserted into the suction pipe support.
[0023] Inside the outer container, partitions can be formed, and multiple inner containers can be combined within the internal space divided by the partitions.
[0024] The outer container is equipped with two pumps. By adjusting the rotation of the components, the discharge rate of one pump can be increased, and the discharge rate of the other pump can be decreased.

[0048] Figure 1 This is a perspective view of a cosmetic container 100 according to an embodiment of the present invention. Figure 2 This is an example of Figure 1 A 3D view showing the state after nozzle 140 has been removed. Additionally, Figure 3 It is along Figure 1 A cross-sectional view of a cosmetic container 100 with AA lines. Figure 4 This is an example Figure 3 A cross-sectional view of the upper part of the cosmetic container 100.
[0049] Reference Figures 1 to 4The cosmetic container 100 of this embodiment is characterized by having two pumps 250 and 270 for pumping out two different contents respectively, and the discharge volume of the pumps 250 and 270 can be adjusted relative to each other by rotating the handle 160 provided on the upper part of the container. For reference, Figure 2 The example illustrates a situation where two pumps, 250 and 270, each discharge the same amount.
[0050] Furthermore, the cosmetic container 100 of this embodiment is characterized by the ability to replace the inner container 110 filled with contents. The cosmetic container 100 of this embodiment is illustrated as having two inner containers 110, each of which can be filled with different types of contents. When the contents of an inner container 110 are used up, the user can easily remove the original inner container 110 and combine it with a new inner container (filled with contents) for use.
[0051] The cosmetic container 100 of this embodiment includes two inner containers 110, a nozzle 140, a handle 160, a shoulder 170, an adjustment component 200, an outer container 220, a base 240, and two pumps 250 and 270. Furthermore, the cosmetic container 100 of the present invention may further include a top cap (not shown) covering the upper part of the nozzle 140.
[0052] Figure 5 This is a perspective view illustrating the internal container 110. Figure 6 It is along Figure 5 A cross-sectional view of the inner container 110 of the CC line.
[0053] Reference Figures 3 to 6 The cosmetic container 100 of this embodiment includes two inner containers 110 capable of being filled with different kinds of contents. The contents filled in the inner containers 110 can be mixed after being individually discharged by pumps 250 and 270. In addition, the two inner containers 110 can have the same shape and can be arranged symmetrically to each other.
[0054] The inner container 110 includes a container body 122 for filling contents. The container body 122 has a semi-circular cross-section and a flat opposing surface 128 formed on the outside. The two inner containers 110 are arranged facing each other with their opposing surfaces 128 facing each other. Furthermore, a connecting thread 124 is formed at the lower part of the inner container 110.
[0055] A label 126 can be attached to the opposite side 128. The label 126 is a peelable film that can record the type or amount of contents filled in the inner container 110. Furthermore, the label 126 can have a downward-protruding handle 127, which the user can pull to easily separate the inner container 110 from the outer container 220.
[0056] The interior of the internal container 110 has a suction tube support 114 and a suction tube 130.
[0057] The suction tube support 114 is connected to the interior of the inner container 110 through an open inlet. The suction tube support 114 has a structure similar to the housing 252 of the pumps 250 and 270, and the housing 252 is inserted into it. In addition, the suction tube support 114 has an outwardly projecting flange 116 at its upper end, which engages with the upper end of the inner container 110.
[0058] The suction tube support 114 has a downwardly protruding connecting protrusion 118. The suction tube 130 is inserted into the connecting protrusion 118. The connecting protrusion 118 is connected to the pumps 250 and 270 and the suction tube 130 respectively, so the contents flowing in through the suction tube 130 can flow into the pumps 250 and 270.
[0059] The suction pipe 130 is a hollow pipe, which serves as a channel for the movement of the contents sucked in by the pumps 250 and 270. The lower end of the suction pipe 130 may be configured adjacent to the bottom surface of the inner container 110.
[0060] The upper inlet of the container body 122 can be fitted with a cap 112. The cap 112 is used to prevent the contents from flowing out or the inflow of foreign objects. In addition, the cap 112 can be removed before being fitted with the outer container 220.
[0061] Figure 7 This is a bottom view illustrating nozzle 140.
[0062] Reference Figure 1 , Figure 4 and Figure 7 The nozzle 140 is the part where the user applies downward pressure, and provides discharge holes 142 and 144 for discharging the two contents. It should be noted that the two contents can be mixed by the user after discharge, without using the two discharge holes 142 and 144 provided by the nozzle 140.
[0063] On the outer peripheral surface of the nozzle 140, a first discharge hole 142 and a second discharge hole 144, corresponding to channels for discharging contents to the outside, are respectively arranged adjacent to each other. Furthermore, the first discharge hole 142 and the second discharge hole 144 communicate with a first channel 146 and a second channel 148 provided inside the nozzle 140. In addition, the first channel 146 and the second channel 148 communicate with a downwardly protruding first protrusion 150 and a second protrusion 152. The first protrusion 150 and the second protrusion 152 are respectively inserted into the interior of the valve 264 of the pumps 250 and 270 via an interference fit. Thus, the nozzle 140 and the valve 264 of the pumps 250 and 270 move up and down integrally.
[0064] If nozzle 140 is pressurized downwards, the contents injected into the internal container 110 are drawn in by pumps 250 and 270 and then individually discharged through the first protrusion 150, the second protrusion 152, the first channel 146, the second channel 148, and the first discharge port 142 and the second discharge port 144. It should be noted that if the external force is removed, nozzle 140 will rise back to its original position due to the elastic restoring force of the spring 266 of pumps 250 and 270.
[0065] Figure 8 and Figure 9 These are, respectively, a perspective view and a sectional view illustrating handle 160.
[0066] Reference Figures 1 to 4 as well as Figures 8 to 9 The handle 160 is located below the nozzle 140 and protrudes outward, serving as the part that the user holds and rotates. The amount of contents discharged from the two pumps 250 and 270 can be adjusted relative to each other by rotating the handle 160 to make the adjusting component 200 rotate as well.
[0067] The handle 160 can be equivalent to a hollow tube of a predetermined length and can have a structure that is open at both the top and bottom. Furthermore, the handle has an outer peripheral surface 162 exposed to the outside. The outer edge of the outer peripheral surface 162 can be fitted with a top cover (not shown). Additionally, the upper end of the outer peripheral surface 162 can form an inwardly protruding upper step 163. The upper step 163 is the portion that holds the lower end of the nozzle 140 in place, thereby preventing the nozzle 140 from separating from the handle 160.
[0068] The inner circumferential surface of the handle 160 has a handle slot 166. Multiple handle slots 166 can be provided at predetermined intervals. The handle slots 166 are inserted into the adjustment protrusion 210 formed at the lower end of the adjustment member 200, thereby allowing the handle 160 and the adjustment member 200 to rotate integrally. In this embodiment, the three handle slots 166 of the handle 160 can be arranged at 120-degree intervals.
[0069] An indicator protrusion 168 may be formed at the lower part of the handle slot 166 on the inner peripheral surface of the handle 160. The indicator protrusion 168 will engage with the shoulder slot 180 formed on the outer peripheral surface of the shoulder 170, thereby allowing the user to sense that the handle 160 has been rotated by a predetermined angle. In this embodiment, the shoulder 170 may have three shoulder slots 180, and each shoulder slot 180 may be configured in a manner corresponding to three positions of the handle 160 (maximum clockwise rotation, maximum counterclockwise rotation, and midpoint).
[0070] On the inner circumferential surface of the handle 160, a rotating groove 164 is formed at the lower part of the indicator protrusion 168. The rotating groove 164 is inserted into the locking protrusion 176 formed inside the insertion groove 174 of the shoulder 170, thereby enabling the handle 160 to be engaged in a manner that allows it to rotate on the upper part of the shoulder 170.
[0071] Figure 10 This is a three-dimensional drawing illustrating a shoulder angle of 170 degrees. Figure 11 It is along Figure 10 A 170-degree cross-sectional view of the shoulder of the BB line.
[0072] Reference Figures 3 to 4 as well as Figures 10 to 11 The shoulder 170 is joined to the upper part of the outer container 220 and rotatably supports the handle 160 joined to its upper part. The shoulder 170 has a cap-like structure with a shoulder top 182, including a lower outer edge surface 172 and an upper outer edge surface 178. In addition, two pump holes 184 for inserting pumps 250 and 270 are formed on the shoulder top 182, and a central protrusion 186 is formed in the center.
[0073] The lower outer edge surface 172 is the portion that inserts into the outer edge of the shoulder mating surface 222 formed on the upper part of the outer container 220, and has a larger diameter compared to the upper outer edge surface 178. It should be noted that a main body mating groove 188 is formed on the inner circumferential surface of the lower outer edge surface 172. A shoulder mating protrusion 224 formed on the upper outer circumferential surface of the outer container 220 is inserted into the main body mating groove 188, thereby mating the shoulder 170 with the upper part of the outer container 220. Furthermore, an anti-rotation protrusion 190 can be formed vertically on the inner circumferential surface of the lower outer edge surface 172. The anti-rotation protrusion 190 is inserted into an anti-rotation groove 226 formed on the upper outer circumferential surface of the outer container 220, thereby non-rotatably mating the shoulder 170 with the upper part of the outer container 220.
[0074] An insertion groove 174 is formed at the connection between the lower outer edge surface 172 and the upper outer edge surface 178. A locking protrusion 176 is formed inside the circular insertion groove 174. The locking protrusion 176 is inserted into a rotating groove 164 formed on the inner peripheral surface of the handle 160, thereby rotatably engaging the handle 160 and the shoulder 170.
[0075] The upper outer edge 178 is the part that is rotatably connected to the handle 160. It should be noted that multiple (e.g., three) shoulder slots 180 can be formed on the outer peripheral surface of the upper outer edge 178. An indicator protrusion 168 formed on the handle 160 can be inserted into the shoulder slot 180, so that the user can sense that the handle 160 is in a specific position or has been rotated to a predetermined angle.
[0076] The shoulder 170 has a shoulder top 182 formed on the upper part of the upper outer edge surface 178. The shoulder top 182 is a horizontal plate with a central protrusion 186 protruding upward from the center. The central protrusion 186 can be detachably inserted into the interior of a connecting protrusion 212 protruding downward inside the adjusting member 200. Pump holes 184 are formed on both sides of the central protrusion 186 on the shoulder top 182. The pump holes 184 extend through the shoulder top 182 and have the same diameter. Pumps 250 and 270 enter and exit through the respective pump holes 184.
[0077] Figure 12 and Figure 13 These are perspective and bottom views illustrating the adjustment component 200, respectively.
[0078] Reference Figures 2 to 4 as well as Figures 12 to 13 The adjusting component 200 is attached to the upper part of the handle 160 and functions to adjust the amount of contents discharged by the two pumps 250 and 270 while rotating integrally with the handle 160. The adjusting component 200 has a cap-like shape with an open lower part, two guide holes 202 formed on the top, and an outer edge surface 206 with a predetermined height.
[0079] The guide hole 202 is formed symmetrically about the center on the upper surface of the adjusting member 200 and has an arc shape. Additionally, a portion of the inner circumferential surface of the guide hole 202 has downwardly protruding pressure protrusions 204 of varying lengths. It should be noted that, referring to… Figure 13 At that time, no pressure protrusion 204 was formed on another part of the inner circumferential surface of the guide hole 202.
[0080] The length of the pressure protrusion 204 can increase linearly towards the end of the guide hole 202. Therefore, referring to... Figure 13 At that time, no pressure protrusion 204 was formed at one end of the guide hole 202 (the part where the pump 270 (dashed line) is located), while the pressure protrusion 204 was formed to the longest length at the other end of the guide hole 202 (the part where the pump 250 (dashed line) is located).
[0081] In the inner circumferential surface of the guide hole 202, the pressure protrusions 204 formed at two points b and c on line a passing through the rotation center (upper center) of the adjusting member 200 can have the same length. Thus, the valve guide 262 of the pumps 250 and 270, which move along the inner circumferential surface of the guide hole 202, can be positioned at the two points ( Figure 13 Points b and c in the middle have pressure protrusions 204 of the same length that apply downward pressure.
[0082] The pressure protrusion 204 pressurizes the valve guide 262 of pumps 250 and 270 downwards. Therefore, inside the guide hole 202, the downward movement distance of the valve guide 262 formed by the pressure protrusion 204 can vary depending on the position of pumps 250 and 270. For example, Figure 13 The intermediate pump 250 is located at the longest portion of the pressurized protrusion 204, so the valve guide 262 is pressurized by the pressurized protrusion 204 and is located at its lowest position. Conversely, the pump 270 is located at the portion where the pressurized protrusion 204 is not formed, so the valve guide 262 is not pressurized and is located at its highest position.
[0083] Thus, when pumps 250 and 270 are not pressurized downwards by nozzle 140, the height of the valve guides 262 of pumps 250 and 270 is pre-adjusted by rotating the adjustment component 200 (i.e., the user rotates the handle 160), thereby regulating the amount of contents discharged by the two pumps 250 and 270 when pressurized by nozzle 140. That is, pump 270, with the highest valve guide 262 height, can discharge the maximum amount of contents when pressurized downwards by nozzle 140, and conversely, pump 250, with the lowest valve guide 262 height, can discharge the minimum amount of contents when pressurized downwards by nozzle 140.
[0084] As the valve guide 262 moves from the end of the guide hole 202 where the pressure protrusion 204 is not formed to the end where the pressure protrusion 204 is formed at its longest point, the downward movement of the valve guide 262 can increase linearly. At the same time, the upward movement of the valve guide 262 of the other pump can also increase linearly. Therefore, as... Figure 2 As shown, when the two pumps 250 and 270 are located in the center of the guide hole 202, the height of the valve guide 262 can be the same, so that the amount of contents discharged by the two pumps 250 and 270 can be the same.
[0085] exist Figure 13 In this state, by rotating the adjusting component 200 counterclockwise, the positions of each pump 250 and 270 can be reversed. At this time, pump 250 can discharge the maximum amount of contents, and the other pump 270 can discharge the minimum amount of contents.
[0086] Valve guide 262 can be located simultaneously at the center of two guide holes 202. Figure 2 (In the state of...), at this time, each pump 250 and 270 can discharge the same amount of contents.
[0087] Thus, the cosmetic container 100 of this embodiment can easily determine the amount of contents discharged by the pumps 250 and 270 by adjusting the position of the valve guide 262 of the pumps 250 and 270 inside the guide hole 202 by rotating the handle 160.
[0088] The adjustment member 200 has an outer edge surface 206 with a predetermined height. Furthermore, an adjustment protrusion 210 protrudes outward from the lower end of the outer edge surface 206. The adjustment protrusion 210 is inserted into a handle slot 166 formed on the inner peripheral surface of the handle 160, thereby allowing the handle 160 and the adjustment member 200 to rotate integrally.
[0089] A connecting protrusion 212 protrudes downward from the center of the interior of the adjusting component 200. The connecting protrusion 212 is a hollow cylindrical shape, and the central protrusion 186 of the shoulder 170 can be detachably inserted inside it.
[0090] Figure 14 and Figure 15 These are, respectively, a perspective view and a sectional view illustrating the outer container 220.
[0091] Reference Figures 2 to 3 as well as Figures 14 to 15 The outer container 220 forms the outer body of the cosmetic container 100, and a plurality of inner containers 110 are detachably attached thereto. In addition, a shoulder 170 is attached to the upper part of the outer container 220, and a base 240 is attached to the lower part.
[0092] The outer container 220 is a hollow cylinder with a placement surface 228 formed at the top and an open bottom. The placement surface 228 has two container holes 230. The upper part of the inner container 110 protrudes into the upper part of the outer container 220 through the container holes 230, and pumps 250 and 270 are inserted into the protruding inner container 110. Therefore, the container holes 230 formed on the placement surface 228 and the pump holes 184 formed on the shoulder 182 are on the same plane and can communicate vertically at predetermined intervals.
[0093] At the center of the placement surface 228, a connecting protrusion 231 protrudes upward between the two container holes 230. The connecting protrusion 231 can be inserted into the central groove 187 formed inside the shoulder 170, thereby allowing the shoulder 170 to engage with the upper part of the outer container 220.
[0094] A shoulder joint surface 222 is formed on the upper outer peripheral surface of the outer container 220. The shoulder joint surface 222 is separated from the outer peripheral surface 221 of the outer container 220 by a step (not shown in the figure). A shoulder joint protrusion 224 is formed outwardly on the shoulder joint surface 222. Furthermore, an anti-rotation groove 226 is formed on the shoulder joint surface 222 in the vertical direction. The anti-rotation groove 226 is located between the shoulder joint protrusions 224.
[0095] The shoulder engagement protrusion 224 is inserted into the main body engagement groove 188 formed on the inner circumferential surface of the shoulder 170, thereby engaging the shoulder 170 with the upper part of the outer container 220. In addition, the anti-rotation groove 226 is inserted into the anti-rotation protrusion 190 formed on the inner circumferential surface of the shoulder 170, thereby preventing the shoulder 170 engaged with the upper part of the outer container 220 from rotating.
[0096] Inside the outer container 220, there is a partition 232 that divides the internal space into two. The internal space of the outer container 220, which is divided by the partition 232, can be detachably connected to the inner container 110.
[0097] A base mating surface 234 is formed on the lower outer peripheral surface of the outer container 220. The base mating surface 234 and the outer peripheral surface 221 of the outer container 220 are separated by a step (not shown in the figure). The base mating surface 234 has an arc shape and two can be arranged facing each other at predetermined intervals. Therefore, the lower end of the inner container 110 inserted into the outer container 220 can be exposed to the outside, so that the user can easily hold the inner container 110. In addition, a thread 236 is formed on the base mating surface 234, and the base 240 can be locked to the lower part of the outer container 220 through the thread 236.
[0098] The base 240 is a cover that covers the lower end of the outer container 220 and covers the inner container 110 that is exposed to the outside to prevent it from detaching.
[0099] Figure 16 These are sectional views illustrating pumps 250 and 270.
[0100] Reference Figures 2 to 3 as well as Figure 16 In this embodiment, the cosmetic container 100 includes two internal containers 110, and correspondingly two pumps 250 and 270. The two pumps 250 and 270 have identical structures and can be coupled to the upper part of each internal container 110 to independently discharge their different contents. Furthermore, the discharge volume of the pumps 250 and 270 can be adjusted by the upper end of the pressure valve guide 262 of the pressure protrusion 204 of the adjusting component 200.
[0101] Since the two pumps 250 and 270 have the same configuration, only pump 250 will be described.
[0102] Pump 250 includes a housing 252. When the inner container 110 is connected to the outer container 220, the housing 252 is inserted into the interior of the suction tube support 114, which is connected to the upper part of the inner container 110. It should be noted that the bottom surface of the housing 252 is in close contact with the bottom surface of the suction tube support 114 to draw in contents. In addition, a valve disc 254, a piston 256, a guide 258, a valve guide 262, and a valve 264 are movably provided in the vertical direction inside the housing 252.
[0103] An outwardly protruding housing flange 253 is formed on the upper outer peripheral surface of the housing 252. The housing flange 253 is placed on top of the flange 116 of the suction pipe support 114, so that the pump 250 is located on the upper part of the suction pipe support 114.
[0104] The valve disc 254, located inside the housing 252, is situated in the passage for drawing in contents (not shown in the accompanying drawings) and opens or closes according to the pressure inside the housing 252. Specifically, the valve disc 254 closes when the nozzle 140 is pressurized downwards and the guide 258, valve 264, and valve guide 262 descend (the inside of the housing 252 is under high pressure compared to the inner container 110). Conversely, the valve disc 254 opens when the external force on the nozzle 140 is removed and the guide 258, valve 264, and valve guide 262 return to their original positions due to the elastic restoring force of the spring 266 (the inside of the housing 252 is under low pressure compared to the inner container 110).
[0105] As disclosed in Korean Patent No. 1975847, valve disc 254 is a conventional technology, so a detailed description is omitted.
[0106] The piston 256, guide 258, valve guide 262 and valve 264 located inside the housing 252 have the same or similar configurations and operations as described in the existing literature, so detailed descriptions are omitted.
[0107] A housing cover 260 is attached to the upper part of the housing 252. Additionally, a spring 266 is provided between the housing cover 260 and the pressure flange 263 of the valve guide 262. The spring 266 causes the valve guide 262, valve 264, and guide 258 to move upwards when the external force on the nozzle 140 is removed.
[0108] Valve 264 is located at the highest point in pump 250, and the first protrusion 150 of nozzle 140 can be inserted into its open upper end. Therefore, the contents drawn in by pump 250 can be discharged to the outside through the first channel 146 connected to the first protrusion 150.
[0109] A valve flange 265 protruding outward is formed on the outer peripheral surface of the upper end of the valve 264. The valve flange 265 is spaced apart from the pressure flange 263 by a predetermined distance, and the guide surface 201 of the adjusting member 200 is inserted into this distance. Therefore, referring to... Figure 2 The valve flange 265 protrudes to the upper part of the guide upper 201, and the pressure flange 263 is located at the lower part of the guide upper 201 and can be pressurized downward by the pressure protrusion 204.
[0110] exist Figure 2 In this state, if the adjusting member 200 rotates due to the rotation of the handle 160, the valve 264 does not descend because the valve flange 265 is stuck on the guide 201; only the valve guide 262 descends due to the downward pressure of the pressure flange 263 by the pressure protrusion 204. Thus, due to the descent of the valve guide 262, a vertical distance is created between the valve 264 and the valve guide 262, and the discharge volume of the pump 250 formed by the pressure of the nozzle 140 decreases proportionally to this distance. That is, because the valve guide 262 moves downward due to the pressure of the adjusting member 200 (at this time, the piston 256 does not descend), the distance between it and the piston 256 decreases. In this state, if the valve guide 262 is further pressed downward due to the downward pressure of the nozzle 140, the piston 256 is pressurized and descends more quickly. As a result, the suction port 259 formed in the guide 258 is closed by the piston 256 more quickly, thereby reducing the amount of contents sucked in.
[0111] The cosmetic container 100 of this embodiment is shown as an example of being combined with two inner containers 110 and having two corresponding pumps 250, 270, but the present invention is not limited to the number of inner containers 110. Therefore, cosmetic containers of other embodiments of the present invention can be combined with one or more inner containers 110.
[0112] The cosmetic container 100 of this embodiment shows an example with a circular outer container 220 and a corresponding semi-circular inner container 110. However, the present invention is not limited to the cross-sectional shapes of the outer and inner containers. Therefore, cosmetic containers of other embodiments of the present invention can have outer and inner containers with cross-sections of various shapes such as quadrilaterals or ellipses.
[0113] The above description refers to an embodiment of the present invention, but those skilled in the art should understand that various modifications and alterations can be made to the present invention without departing from the spirit and field of the present invention as described in the claims.
