Description

Technical Field

[0001] The present invention relates to a cosmetic container, and more particularly to a cosmetic container including a structure capable of minimizing the residual pressure during the discharge of the contents by increasing the internal pressure of the container by turning a dial.

Background Art

[0002] Generally, people have the desire to beautify themselves through makeup. Therefore, people obtain a sense of satisfaction by applying makeup to various parts such as the skin, lips, nails, and hair in various ways.

[0003] In the case of lips, there are widely used makeup methods to make the lips stand out from the face or to dissolve the keratin of the lips to make them smooth and firm. Here, people use lip packs, lipsticks, lip glosses, lip balms, lip tints, etc. to apply makeup to the lips. At this time, lip packs not only make the lips look beautiful, but also prevent the lips from drying and becoming rough, and have the effect of making the lips smooth and firm.

[0004] Lip packs can be used on the lips in terms of the usage form of the container, and depending on the type of dosage form, the container can be held and directly applied to the body part, or it can be applied using the hand or other tools.

[0005] Lip packs are manufactured in various shapes such as cylindrical. When the lip pack is cylindrical, recently, the contained cosmetics are discharged and used by increasing the internal pressure of the container by turning a dial.

[0006] However, in the case of conventional cylindrical lip packs, when using cosmetics with high viscosity or hardness, there is a phenomenon that some cosmetics come out due to the residual pressure even after turning the dial, which is inconvenient for use.

Summary of the Invention

Problems to be Solved by the Invention

[0007] The present invention was created to solve the problems of the prior art described above, and the objective of the present invention is to provide a cosmetic container that can minimize the residual pressure inside the container body when dispensing the contents by increasing the internal pressure of the container body by turning a dial. [Means for solving the problem]

[0008] A cosmetic container according to one aspect of the present invention includes a container section for containing contents in a container body whose upper part is sealed by an upper cover section and which has a discharge port at the top; a lower cover section for sealing the open lower part of the container body; a pressurizing section for pressurizing the inside of the container body to discharge the contents; and an auxiliary section for raising and lowering the pressurizing section while rotating, wherein the pressurizing section can alternately perform upward and downward movements while pressurizing the inside of the container body while being raised by the auxiliary section in order to discharge the contents of the container body.

[0009] Specifically, the pressurizing section can increase the internal pressure of the container body through upward movement to discharge the contents, and eliminate any remaining pressure in the container body through downward movement.

[0010] Specifically, the pressurizing section may include a head section that moves up and down in close contact with the inner circumferential surface of the container body, and a pressurizing structure section that connects with the auxiliary section at the lower part of the head section, causing the head section to alternately move upward and downward while it is moving up and down.

[0011] Specifically, the head portion is provided with a plurality of second guide protrusions on its outer circumferential surface, and the pressurizing structure includes a first annular member connected to the head portion and having a diameter smaller than the diameter of the head portion, with its lower surface having a first wave shape, a second annular member connected to the first annular member and having a diameter smaller than the diameter of the first annular member, and a third annular member connected to the second annular member and having the same diameter as the first annular member, with its upper surface having a second wave shape, and the pressurizing structure can form pressurizing guidelines by the first annular member, the second annular member, and the third annular member so that upward and downward movements alternately occur while the head portion moves up and down.

[0012] Specifically, the first waveform shape and the second waveform shape are both sinusoidal, with repeating troughs and peaks and the same period. The distance between a trough and a peak can be the same as the distance between a peak and an adjacent trough, longer than the distance between a peak and another trough, or shorter than the distance between a peak and another trough.

[0013] Specifically, the auxiliary part includes a plurality of pressurizing protrusions that are inserted into the pressurizing guideline. The plurality of pressurizing protrusions rotate and rise while inserted into the pressurizing guideline, moving from the peak portion to the trough portion of the first wave shape, thereby causing the head portion to move upward, increasing the internal pressure of the container body so that the contents are discharged through the outlet. The plurality of pressurizing protrusions rotate and rise while inserted into the pressurizing guideline, moving from the trough portion to the peak portion of the first wave shape, thereby causing the head portion to move downward, lowering the internal pressure of the container body so that the contents do not leak to the outside due to residual pressure.

[0014] Specifically, the pressurizing section increases the downward momentum of the head portion as the height difference between the peak and trough portions of the first waveform shape increases, thereby increasing the amount of residual pressure inside the container body that is released. The height difference can be any one of 0.25 mm, 0.35 mm, or 0.45 mm.

[0015] Specifically, the pressurizing section can be configured such that the contents are discharged once during a rotational movement in one cycle, while the multiple pressurizing protrusions are inserted into the pressurizing guideline and rotate upward, moving from one peak of the first wave shape to the next adjacent peak.

[0016] Specifically, the pressurized section is configured such that the smaller the distance value between the trough portion of the first waveform shape and the other trough portion, or between the peak portion and the other peak portion, i.e., the angle value (based on the circle), the shorter the cycle period, thereby increasing the number of times the contents are dispensed and decreasing the amount of contents dispensed relative to a 360-degree rotation. The angle value can be any one of 9 degrees, 18 degrees, 22.5 degrees, 45 degrees, and 90 degrees relative to one cycle.

[0017] The head portion is provided with a plurality of second guide protrusions on its outer circumferential surface, and the pressurizing structure includes a first annular member connected to the head portion and having a diameter smaller than the diameter of the head portion, with its lower surface having a first wave shape, a second annular member connected to the first annular member and having a diameter smaller than the diameter of the first annular member, and a third annular member connected to the second annular member and having the same diameter as the first annular member, with its upper surface having a second wave shape, and the pressurizing structure can form pressurizing guidelines by the first annular member, the second annular member, and the third annular member so that upward and downward movements alternately occur while the head portion moves up and down.

[0018] Specifically, the first waveform shape and the second waveform shape are both sinusoidal, with repeating troughs and peaks and the same period. The distance between a trough and a peak can be the same as the distance between a peak and an adjacent trough, longer than the distance between a peak and another trough, or shorter than the distance between a peak and another trough.

[0019] Specifically, the auxiliary part includes a plurality of pressurizing protrusions that are inserted into the pressurizing guideline. While the plurality of pressurizing protrusions rotate and rise while inserted into the pressurizing guideline, they move from the peak portion to the trough portion of the first wave shape, causing the head portion to move upward, thereby increasing the internal pressure of the container body and causing the contents to be discharged through the outlet. While the plurality of pressurizing protrusions rotate and rise while inserted into the pressurizing guideline, they move from the trough portion to the peak portion of the first wave shape, causing the head portion to move downward, thereby decreasing the internal pressure of the container body and preventing the contents from leaking out due to residual pressure.

[0020] Specifically, the pressurizing section increases the downward momentum of the head portion as the height difference between the peak portion and the trough portion of the first waveform shape increases, thereby increasing the amount of residual pressure inside the container body that is released. The height difference can be any one of 0.25 mm, 0.35 mm, or 0.45 mm.

[0021] Specifically, the pressurizing section can be configured such that the contents are discharged once while the pressurizing protrusions are inserted into the pressurizing guideline and rotate upward, moving from one peak of the first wave shape to the next adjacent peak in one cycle.

[0022] Specifically, the pressure part is configured such that the smaller the distance value, i.e., the angular value (with reference to a circle), between the valley part of the first waveform shape and the other valley part, or between the peak part and the other peak part, the shorter the period of one cycle, and the number of discharges of the content increases and the discharge amount of the content decreases with reference to a 360-degree rotation. The angular value can be any one of 9 degrees, 18 degrees, 22.5 degrees, 45 degrees, and 90 degrees with reference to one cycle.

[0023] Specifically, the surface where the discharge port is provided can be any one of convex, concave, and flat shapes, and is formed of at least one of metal, aluminum, zamak, ceramic, and plastic. The discharge port can be formed in any one of circular and wavy shapes.

[0024] Specifically, it can further include an intermediate part that applies a rotational force to the auxiliary part, a fixing plate fixed to the lower cover part, and a shaft part provided with a male screw column supported by the fixing plate and extending to the upper part of the container body.

[0025] Specifically, the lower cover part applies a rotational force to the auxiliary part. The lower cover part and the intermediate part can directly apply a rotational force to the auxiliary part or indirectly apply a rotational force to the auxiliary part through the container body.

[0026] Specifically, the container part includes a plurality of coupling protrusions provided on a part of the outer peripheral surface of the upper part of the container body, and a plurality of guide grooves provided at regular intervals in a groove shape extending from the lower part to the upper part on the inner peripheral surface of the container body. The intermediate part includes an intermediate body provided in the form of an outer skin on the outer peripheral surface of the container body and rotatable, and a plurality of coupling grooves that couple with the plurality of coupling protrusions on a part of the upper inner peripheral surface. The auxiliary part can include a receiving plate provided with a female screw member screwed to the male screw column of the shaft part at the center, and a plurality of first guide protrusions provided on the outer peripheral surface of the receiving plate and inserted into the plurality of guide grooves of the container body.

[0027] Specifically, when the middle part rotates, the container body rotates together and transmits the rotational force of the middle part to the auxiliary part. When the lower cover part rotates, the shaft part rotates together and transmits the rotational force of the lower cover part to the auxiliary part. The auxiliary part can move up and down along the male screw column while rotating by receiving the transmission of the rotational force from the container body or the shaft part, thereby moving the pressurizing part up and down.

[0028] Specifically, the auxiliary part consists of a first auxiliary part and a second auxiliary part provided between the shaft part and the pressurizing part. The first auxiliary part includes a receiving plate mounted on the fixing plate of the shaft part, a plurality of first guide protrusions provided on the outer peripheral surface of the receiving plate and inserted into the plurality of guide grooves of the container body, and a female screw member provided at the center of the receiving plate and screw-coupled to the male screw column of the shaft part. The second auxiliary part includes a frame that houses the pressurizing structure part and has a plurality of incision grooves formed at regular intervals so as to have an elastic force, a plurality of pressurizing protrusions provided on the inner surface of the frame and inserted into the pressurizing guide line, a coupling column that protrudes upward from the center of the frame and is inserted into the coupling hole of the pressurizing structure part and has a first insertion hole penetrating vertically through which the male screw column of the shaft part is inserted, and a fixing protrusion provided at the lower part inside the frame and fixed to the fixing groove of the pressurizing structure part.

[0029] Specifically, the shaft part includes a plurality of insertion grooves provided at regular intervals on the outer peripheral surface of the fixing plate, and the plurality of insertion grooves can be coupled to a plurality of fixing bars provided inside the lower cover part.

[0030] Specifically, the container body includes a sound bar provided along the edge of the open lower part and having an elastic force. The lower cover part includes a plurality of sound protrusions continuously provided along the inner surface. When the container body is rotated by the rotation of the middle part, the sound bar can rub against the plurality of sound protrusions to generate sound.

[0031] Specifically, the container portion is fastened to the upper cover portion by fastening means, and the fastening means includes a fastening groove provided along the inner circumferential surface of the upper cover portion, and a fastening projection provided continuously or discontinuously along the outer circumferential surface of the container body, which is fastened to the fastening groove in a snap-on manner without horizontal restraint, and the fastening means prevents the rotational force of the lower cover portion from being transmitted to the shaft portion and prevents the contents from being discharged when the lower cover portion is rotated while the upper cover portion is fastened to the container portion.

[0032] Specifically, in the cosmetic container, each time the pressurizing part rotates on the first annular member from the peak portion to the valley portion and then to the adjacent peak portion, one of the multiple sound protrusions is rubbed against the sound bar once, and the contents are dispensed once while the pressurizing part moves from the peak portion to the valley portion (upward movement of the pressurizing part) during the rotational movement of one cycle, but not while it moves from the valley portion to the other peak portion (downward movement of the pressurizing part).

[0033] Specifically, the multiple sound protrusions can be arranged at regular intervals on the inner surface of the lower cover in a number corresponding to the sum of the number of upward and downward movements of the pressurizing section divided by 2.

[0034] Specifically, the angle value of one cycle of the pressurizing section corresponds to a value obtained by dividing 360 degrees by a multiple of 4, and the multiple sound protrusions can be arranged at regular intervals on the inner surface of the lower cover, with the angle value corresponding to one cycle of the pressurizing section being the arrangement angle value.

[0035] Specifically, each of the multiple sound protrusions is arranged to correspond to the trough portion of the first waveform shape, which is the point at which the ejection of the contents is completed once, so that the number of times the contents have been ejected can be confirmed.

[0036] Cosmetic products according to other aspects of the present invention may include the cosmetic container described above and cosmetic contents contained in the cosmetic container. [Effects of the Invention]

[0037] The cosmetic container according to the present invention is configured such that the pressurizing section alternates between upward and downward movements while pressurizing the inside of the container body. The upward movement of the pressurizing section increases the internal pressure of the container body, causing the contents to be dispensed, while the downward movement eliminates any remaining pressure in the container body. This prevents some of the contents from leaking out due to residual pressure, thus eliminating inconvenience to the user and improving satisfaction. [Brief explanation of the drawing]

[Modes for carrying out the invention]

Note that in this specification, when assigning reference numerals to components in each drawing, the same component has been assigned the same number whenever possible, even if it appears in different drawings. Furthermore, in describing the present invention, if a specific description of related prior art is deemed to unnecessarily obscure the gist of the invention, such detailed description will be omitted.

[0040] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0042] Referring to Figures 1 to 10, a cosmetic container according to one embodiment of the present invention can be configured such that, while pressurizing the inside of the container body 21, the pressurizing means moves upward and downward alternately, thereby increasing the internal pressure of the container body 21 by the upward movement to discharge the contents, and eliminating any remaining pressure in the container body 21 by the downward movement.

[0043] Residual pressure remains greater when the viscosity and hardness of the contents are high. In other words, when the viscosity and hardness of the contents are low, the pressure applied inside the container body 21 is entirely used for discharging the contents. However, when the viscosity and hardness of the contents are high, the discharging speed of the contents slows down, inevitably leaving residual pressure, which inconveniences the user as they have to deal with the contents that seep out due to the residual pressure.

[0044] The cosmetic container of this embodiment may include an upper cover portion 1, a container portion 2, a lower cover portion 3, an intermediate portion 4, a shaft portion 5, an auxiliary portion 6, and a pressurizing portion 7.

[0045] The cosmetic container may include a container section 2 that houses the contents in a container body 21 having a discharge port 22 at its top; a lower cover section 3 that seals the open lower part of the container body 21 and applies rotational force to an auxiliary section 6 while gripping the intermediate section 4, or grips the intermediate section 4 when it is rotated; an intermediate section 4 that applies rotational force to the auxiliary section 6 while gripping the lower cover section 3, or grips the lower cover section 3 when it is rotated; a shaft section 5 that is supported by a fixing plate 51 fixed to the lower cover section 3 and has a male screw column 53 that extends to the top of the container body 21; an auxiliary section 6 that moves the pressurizing section 7 up and down while rotating; and a pressurizing section 7 that pressurizes the inside of the container body 21 to discharge the contents.

[0046] In this embodiment, the cosmetic container may be configured such that when the user grips the lower cover portion 3 and fixes the shaft portion 5, and rotates the intermediate portion 4, the rotational force of the intermediate portion 4 is transmitted to the container body 21, the rotational force of the container body 21 is transmitted to the auxiliary portion 6, the auxiliary portion 6 physically rises along the shaft portion 5, and the internal residual pressure of the container body 21 can be removed by the pressurizing portion 7, which is configured to repeatedly move upward and downward while rising together with the auxiliary portion 6 as it rises.

[0047] Furthermore, the cosmetic container of this embodiment may be configured such that when the user grips the intermediate part 4 and rotates the lower cover part 3 to which the shaft part 5 is fixed, the rotational force of the lower cover part 3 is transmitted to the auxiliary part 6, causing the auxiliary part 6 to physically rise along the shaft part 5. The pressurizing part 7 is configured to repeatedly move upward and downward while rising together with the auxiliary part 6 as it rises, thereby removing the residual pressure inside the container body 21.

[0048] The cosmetic container and its contents according to this embodiment can be included in a cosmetic product.

[0049] The upper cover portion 1 can seal the top of the container portion 2.

[0050] The upper cover portion 1 may be equipped with a stopper 11 inside. The stopper 11 can be inserted into a discharge port 22 provided at the top of the container portion 2 to seal the container portion 2.

[0051] The container section 2 can contain contents and may include a container body 21, a discharge port 22, multiple connecting protrusions 23, at least one sound bar 24, and multiple guide grooves 25.

[0052] Referring to Figure 5, the container body 21 may be cylindrical with a discharge port 22 at the top and an open bottom. In this embodiment, the case where the container body 21 is cylindrical is described, but it goes without saying that it can be realized in various shapes such as polygons.

[0053] The surface of the container body 21 on which the discharge port 22 is provided is one of the shapes of convex, concave, and flat, and can be made of at least one of metal, aluminum, Zamac, ceramic, or plastic.

[0054] The discharge port 22 can be formed in either a circular or wavy shape.

[0055] Multiple connecting protrusions 23 may be provided on a part of the upper outer surface of the container body 21.

[0056] Multiple connecting protrusions 23 can be connected to multiple connecting grooves 42 provided on the upper inner circumferential surface of the intermediate body 41.

[0057] The container body 21 described above can rotate by receiving rotational force from the intermediate part 4 through the connection of multiple connecting protrusions 23 with multiple connecting grooves 42 of the intermediate body 41.

[0058] At least one sound bar 24 is formed along the open lower edge of the container body 21, but may also be formed by cutting a portion of the container body 21 to give it elasticity.

[0059] At least one soundbar 24 can generate sound by rubbing against a plurality of sound protrusions 32 that are continuously provided along the inner surface of the lower cover portion 3.

[0060] In other words, when the container body 21 is rotated by the rotation of the intermediate part 4, at least one sound bar 24 rubs against multiple sound protrusions 32 to generate sound.

[0061] Multiple guide grooves 25 may be provided on the inner circumferential surface of the container body 21 at regular intervals, extending in a groove-like manner from the bottom to the top.

[0062] Multiple guide grooves 25 into which multiple first guide protrusions 612 provided on the auxiliary part 6 can be inserted, thereby guiding the raising and lowering of the auxiliary part 6.

[0063] Furthermore, multiple second guide protrusions 711 provided on the pressurizing section 7 can be inserted into the multiple guide grooves 25, thereby guiding the upward and downward movement of the pressurizing section 7.

[0064] The container body 21, configured as described above, can rotate together with the intermediate section 4 when the lower cover section 3 is held, thereby transmitting the rotational force of the intermediate section 4 to the auxiliary section 6.

[0065] Furthermore, the container body 21 can also rotate the lower cover portion 3 while gripping the middle portion 4, thereby transmitting the rotational force of the lower cover portion 3 to the auxiliary portion 6.

[0066] The lower cover portion 3 can seal the open lower part of the container body 21 and may include multiple fixing bars 31 and multiple sound protrusions 32.

[0067] Multiple fixing bars 31 may be provided inside the lower cover portion 3 and can be connected to multiple insertion grooves 52 provided on the outer circumferential surface of the fixing plate 51 of the shaft portion 5.

[0068] Multiple sound protrusions 32 may be provided continuously along the inner surface of the lower cover portion 3.

[0069] The multiple sound protrusions 32 may be gently hemispherical in shape, as shown in Figure 10. The multiple sound protrusions 32 can represent a variety of shapes for the surface that contacts at least one or more sound bars 24.

[0070] Multiple sound protrusions 32 are provided along the open lower edge of the container body 21 and can generate sound by rubbing against at least one sound bar 24 while the container body 21 rotates.

[0071] Thus, when the device rotates in the direction of discharging the contents, bending the shape of the contact surfaces of the multiple sound protrusions 32 and at least one sound bar 24 in the direction of rotation and the opposite direction of rotation generates sound due to friction during rotation in both directions. By diversifying the shapes of the multiple sound protrusions 32 and diversifying the material of at least one sound bar 24 that generates sound, the user can hear a variety of sounds, thus providing an auditory effect for the user.

[0072] Furthermore, at least one soundbar 24 may be formed in a shape having a first inclined surface 241 on one side and a first vertical surface 242 on the other side, as shown in Figure 11.

[0073] Furthermore, the multiple sound protrusions 32 may be formed in a shape where one side has a second inclined surface 321 and the other side has a second vertical surface 322, as shown in Figure 12.

[0074] In the above configuration, when at least one sound bar 24 and multiple sound protrusions 32 come into contact, the first inclined surface 241 and the second inclined surface 321 come into contact, and the first vertical surface 242 and the second vertical surface 322 come into contact.

[0075] As a result, the multiple sound protrusions 32 and at least one sound bar 24 can embody the function of a reverse rotation stopper, restricting rotation in the reverse direction by the first vertical surface 242 and the second vertical surface 322.

[0076] The intermediate section 4 can grip the lower cover section 3 and apply rotational force to the auxiliary section 6.

[0077] The intermediate section 4 can either directly apply rotational force to the auxiliary section 6 or indirectly apply rotational force to the auxiliary section 6 via the container body 21. In this embodiment, the case in which the intermediate section 4 indirectly applies rotational force to the auxiliary section 6 will be described.

[0078] The intermediate section 4 can be rotated in the forward or reverse direction using a dial, and may include an intermediate body 41 and a plurality of coupling grooves 42.

[0079] The intermediate body 41 may be provided on the outer surface of the container body 21 in the form of an outer shell.

[0080] The intermediate body 41 is rotatable while in contact with the outer surface of the container body 21.

[0081] Multiple coupling grooves 42 may be provided on a part of the upper inner circumferential surface of the intermediate body 41, and can be coupled with multiple coupling protrusions 23 provided on the upper outer circumferential surface of the container body 21.

[0082] The intermediate section 4 described above can transmit rotational force to the container body 21 by having multiple coupling grooves 42 that connect with multiple coupling protrusions 23 of the container body 21.

[0083] In this embodiment, as described above, the internal residual pressure of the container body 21 can be removed by rotating the intermediate part 4 while gripping the lower cover part 3 and fixing the shaft part 5.

[0084] In other words, the mechanism for gripping the lower cover portion 3 and rotating the intermediate portion 4 is such that the rotational force of the intermediate portion 4 is transmitted to the container body 21, and the rotational force transmitted to the container body 21 is transmitted to the auxiliary portion 6. At this time, the first auxiliary portion 61, which is the lower component of the auxiliary portion 6, rotates due to the rotational force and rises along the shaft portion 5, and the second auxiliary portion 62, which is the upper component of the auxiliary portion 6, rises along the shaft portion 5 by the first auxiliary portion 61. While the auxiliary portion 6 is physically rising along the shaft portion 5 in this way, the pressurizing portion 7 rises and repeats upward and downward movements. When the pressurizing portion 7 rises, the contents of the container body 21 are discharged, and when the pressurizing portion 7 subsequently descends, the residual pressure inside the container body 21 is removed.

[0085] In this case, the intermediate section 4 can either directly apply rotational force to the auxiliary section 6, or indirectly apply rotational force to the auxiliary section 6 via the container body 21.

[0086] Furthermore, in this embodiment, unlike the above, the internal residual pressure of the container body 21 can be removed by rotating the lower cover portion 3 to which the shaft portion 5 is fixed while the intermediate portion 4 is being held.

[0087] In other words, the mechanism for gripping the intermediate part 4 and rotating the lower cover part 3 is such that the rotational force of the lower cover part 3 is transmitted to the auxiliary part 6. At this time, the first auxiliary part 61, which is the lower component of the auxiliary part 6, only rises along the shaft part 5, while the second auxiliary part 62, which is the upper component of the auxiliary part 6, rotates and rises along the shaft part 5 by the first auxiliary part 61. While the auxiliary part 6 is physically rising along the shaft part 5 in this way, the pressurizing part 7 rises and repeatedly moves up and down. When the pressurizing part 7 moves up, the contents of the container body 21 are discharged, and when the pressurizing part 7 subsequently moves down, the residual pressure inside the container body 21 is removed.

[0088] In this case, the lower cover portion 3 can either directly apply rotational force to the auxiliary portion 6, or indirectly apply rotational force to the auxiliary portion 6 via the container body 21.

[0089] The shaft portion 5 is fixed to the lower cover portion 3, allowing the auxiliary portion 6 and the pressurizing portion 7, which are provided inside the container body 21, to be stably fixed.

[0090] The shaft portion 5 rotates together with the lower cover portion 3 when it is rotated, and can transmit the rotational force of the lower cover portion 3 to the auxiliary portion 6.

[0091] The shaft section 5 can raise and lower the auxiliary section 6 and guide the raising and lowering of the pressurizing section 7.

[0092] The shaft portion 5 may include a fixing plate 51, a plurality of insertion grooves 52, and a male threaded column 53.

[0093] The fixing plate 51 may be fixed to the lower cover portion 3.

[0094] Multiple insertion grooves 52 may be provided at regular intervals on the outer surface of the fixing plate 51.

[0095] The multiple insertion grooves 52 may be connected to multiple fixing bars 31 provided on the inside of the lower cover portion 3, thereby allowing the shaft portion 5 to be fixed to the lower cover portion 3.

[0096] The male threaded column 53 may be supported by the fixing plate 51 and extended to the top of the container body 21. The male threaded column 53 has screw threads, and the pitch spacing of the threads

[0097] The male threaded column 53 can be screw-connected to the female threaded member 613 of the first auxiliary part 61, allowing the first auxiliary part 61 to rotate and move up and down.

[0098] Furthermore, the male screw column 53 can be inserted into the second insertion hole 712 of the head portion 71 to guide the up and down movement of the head portion 71.

[0099] The auxiliary unit 6 receives rotational force transmitted from the container body 21 or the shaft unit 5 and rotates while moving up and down along the male screw column 53, thereby allowing the pressurizing unit 7 to be raised and lowered.

[0100] The auxiliary section 6 can raise and lower the pressurizing section 7 by rotating, and may include a first auxiliary section 61 and a second auxiliary section 62. In this embodiment, the case in which the first auxiliary section 61 and the second auxiliary section 62 are separate is described, but it goes without saying that they may be formed as a single unit.

[0101] The first auxiliary section 61 and the second auxiliary section 62 may be provided between the shaft section 5 and the pressurizing section 7.

[0102] The first auxiliary portion 61 may be provided between the shaft portion 5 and the second auxiliary portion 62, and may include a receiving plate 611, a plurality of first guide protrusions 612, and a female screw member 613.

[0103] The receiving plate 611 may be mounted on the fixing plate 51 of the shaft portion 5, and can accommodate the lower part of the second auxiliary portion 62.

[0104] Multiple first guide protrusions 612 may be provided on the outer circumferential surface of the receiving plate 611, and a female threaded member 613 may be provided in the center, which is screw-connected to the male threaded column 53 of the shaft portion 5.

[0105] Multiple first guide protrusions 612 may be provided on the outer circumferential surface of the receiving plate 611.

[0106] Multiple first guide protrusions 612 can be inserted into multiple guide grooves 25 of the container body 21, and the first auxiliary part 61 can be moved up and down along the inner surface of the container body 21 by receiving rotational force from the container body 21.

[0107] The female thread member 613 may be provided in the center of the receiving plate 611.

[0108] The female threaded member 613 can be screw-connected to the male threaded column 53 of the shaft portion 5, and by receiving rotational force transmitted from the container body 21, it can rotate and move up and down along the male threaded column 53, thereby raising and lowering the pressurizing portion 7.

[0109] The second auxiliary section 62 may be provided between the first auxiliary section 61 and the pressurizing section 7, and may include a frame 621, an incision groove 622, a plurality of pressurizing protrusions 623, a connecting column 624, a first insertion hole 625, and a fixing protrusion 626.

[0110] The second auxiliary section 62 can be connected to the pressurizing structure section 72 of the pressurizing section 7 while housed in the first auxiliary section 61.

[0111] The frame 621 houses the pressurized structure 72, and multiple incision grooves 622 can be formed at regular intervals to provide elasticity.

[0112] The incision groove 622 allows the frame 621 to have elastic force when it rotates with multiple pressure projections 623 provided on the inside of the frame 621 inserted into the pressure guideline having a curved surface provided on the pressure structure 72.

[0113] Here, although the pressurization guidelines will be described later, the pressurization structure 72 may be formed to have a shape that is bent vertically by a first annular member 721 having a first wave shape, a second annular member 722, and a third annular member 723 having a second wave shape, so that while the head portion 71 moves up and down, upward and downward movements alternately occur.

[0114] Multiple pressure protrusions 623 are provided on the inner surface of the frame 621 and can be inserted into the pressure guideline. Although the drawings show two pressure protrusions 623, there may be four, and the number is not limited to these.

[0115] The multiple pressure protrusions 623 rotate around the pressure structure 72 along the pressure guideline, causing the head portion 71 to alternately perform upward and downward movements.

[0116] As the multiple pressurizing protrusions 623 rotate and rise while inserted into the pressurizing guideline, moving from the peak portion to the trough portion of the first wave shape, the head portion 71 can be moved upward. As a result, the contents contained in the container body 21 can be discharged through the discharge port 22 as the internal pressure of the container body 21 increases due to the upward movement of the head portion 71.

[0117] Furthermore, while the multiple pressurizing protrusions 623 are inserted into the pressurizing guideline, they rotate and rise, moving from the troughs to the peaks of the first wave shape, allowing the head portion 71 to move downwards. As a result, the contents contained in the container body 21 will not leak out as the internal pressure of the container body 21 decreases due to the downward movement of the head portion 71, eliminating any residual pressure.

[0118] The connecting column 624 may be provided so as to protrude upward from the center of the frame 621.

[0119] The connecting column 624 can be sized to be inserted into the connecting hole 725 of the pressurized structure 72.

[0120] The connecting column 624 may be provided with a first insertion hole 625 that penetrates vertically.

[0121] The male threaded column 53 of the shaft portion 5 may be inserted into the first insertion hole 625.

[0122] The connecting column 624 has a certain height, and the male threaded column 53 is inserted into the first insertion hole 625 which penetrates in the height direction, so that the second auxiliary part 62 can move up and down stably without swaying on the male threaded column 53.

[0123] Furthermore, the first insertion hole 625 is inserted into the second insertion hole 712, minimizing or sealing the space between the male threaded column 53 and the second insertion hole 712, thereby preventing the contents from leaking out to the lower end.

[0124] The fixing projection 626 may be provided on the lower inside of the frame 621.

[0125] The fixing projection 626 may be fixed to the fixing groove 724 of the pressurizing structure 72, thereby allowing the pressurizing structure 72 to be fixedly attached to the second auxiliary part 62.

[0126] The pressurizing unit 7 can pressurize the inside of the container body 21 to dispense the contents.

[0127] The pressurizing section 7 can alternately perform upward and downward movements while pressurizing the inside of the container body 21 as it rises, with the help of the auxiliary section 6 for discharging the contents of the container body 21.

[0128] The pressurizing section 7 increases the internal pressure of the container body 21 through upward movement, causing the contents to be discharged, and eliminates any remaining pressure in the container body 21 through downward movement.

[0129] Such a pressurized section 7 may include a head section 71 and a pressurized structure section 72.

[0130] The head portion 71 may be provided so as to be in close contact with the inner circumferential surface of the container body 21.

[0131] As the head section 71 moves up and down, the pressurizing structure section 72 can cause it to repeatedly move up and down alternately. The upward movement increases the internal pressure of the container body 21, causing the contents to be discharged through the discharge port 22, and the downward movement eliminates any remaining pressure in the container body 21.

[0132] Multiple second guide protrusions 711 may be provided on the outer circumferential surface of the head portion 71.

[0133] Multiple second guide protrusions 711 may be inserted into multiple guide grooves 25 provided on the inner surface of the container body 21, and the raising and lowering of the auxiliary part 6 can guide the raising and lowering of the head part 71.

[0134] The pressurized structure 72 can be connected to the auxiliary part 6 at the lower part of the head part 71.

[0135] The pressurized structure 72 may be configured such that the head portion 71 alternates between upward and downward movements while the head portion 71 is moving up and down, and may include a first annular member 721, a second annular member 722, a third annular member 723, a fixing groove 724, and a coupling hole 725.

[0136] The first annular member 721 can be connected to the head portion 71.

[0137] The first annular member 721 can have a diameter smaller than the diameter of the head portion 71, and its lower surface can have a first corrugated shape.

[0138] The second annular member 722 can be connected to the first annular member 721.

[0139] The second annular member 722 may have a diameter smaller than the diameter of the first annular member 721.

[0140] The third annular member 723 can be connected to the second annular member 722.

[0141] The third annular member 723 can have the same diameter as the first annular member 721, and its upper surface can have a second corrugated shape.

[0142] The first annular member 721 and the third annular member 723 described above have a shape that is bent vertically according to the first and second wave shapes, and a pressure guideline may be formed so that upward and downward movements alternately occur while the head portion 71 moves up and down.

[0143] The pressurized structure 72 configured as described above can be configured such that the contents are discharged once during a rotational movement in one cycle, as the multiple pressurized protrusions 623 are inserted into the pressurized guideline and rotate upward, moving from one peak of the first or second wave shape to the next adjacent peak.

[0144] In the above, the first and second waveform shapes may each be sinusoidal, with repeating troughs and peaks and the same period, as shown in Figures 6 to 8.

[0145] The first wave shape of the first annular member 721 and the second wave shape of the third annular member 723 can have the troughs and peaks of a sinusoidal wave coincide.

[0146] Referring to Figure 6, in the pressurized structure 72 configured as described above, the space between the peaks and troughs of the first wave shape of the first annular member 721 and the second wave shape of the third annular member 723 can be formed to have a first height value h1.

[0147] Furthermore, in the pressurized structure 72, the distance between a trough portion of the first wave shape of the first annular member 721 or the second wave shape of the third annular member 723 and an adjacent trough portion or an adjacent peak portion can be formed to have a first distance value d1. Here, the first wave shape of the first annular member 721 can serve as the reference, because even if the third annular member 723 does not have a second wave shape, the pressurized structure 72 can perform upward and downward movements based on the first wave shape. That is, when multiple pressurized protrusions 623 are inserted into the pressurized guideline and rotate along the first wave shape of the first annular member 721, passing through the trough portions and peak portions, the pressurized structure 72 will perform upward and downward movements. However, the second wave shape of the second annular member 722 alone cannot realize the upward and downward movements of the pressurized structure 72.

[0148] In the above configuration, the pressurized structure 72 can adjust the first high / low value h1 to effectively deal with the residual pressure difference that varies depending on the viscosity or hardness of the contents.

[0149] Furthermore, the pressurized structure 72 can adjust the number of times the contents are dispensed and the amount of contents dispensed based on a 360-degree rotation by adjusting the first distance value d1, i.e., the angle value (circle reference). During the 360-degree rotation, it can effectively deal with the residual pressure difference that changes according to the hardness by repeating the up-and-down motion multiple times. Here, the number of times and the amount of contents dispensed in one go are defined as the movement of the pressurized projection 623 from the peak to the trough of the first wave shape of the first annular member 721 or the second wave shape of the third annular member 723, while rotating and rising with the pressurized projection 623 inserted into the pressurized guideline of the pressurized structure 72. That is, the contents are dispensed once while moving from one peak to the other.

[0150] Referring to Figure 7, in the other embodiment, the pressurized structure 72 has the same first distance value d1 as the pressurized structure 72 shown in Figure 6, where the distance between a trough portion of the first wave shape of the first annular member 721a or the second wave shape of the third annular member 723a and adjacent trough portions or adjacent peak portions is the same. However, the distance between the peak portions and trough portions of the first wave shape of the first annular member 721a and the second wave shape of the third annular member 723a is formed by a second height value h2 that is greater than the first height value h1 of the pressurized structure 72 shown in Figure 6.

[0151] Alternatively, the second waveform shape of the second annular member 722 may have sinusoidal valleys and peaks opposite to the first waveform shape of the first annular member 721 and the third waveform shape of the third annular member 723.

[0152] Furthermore, in the pressurized structure 72, the distance between a valley portion of the second wave shape of the second annular member 722 and an adjacent valley portion, or between a peak portion and an adjacent peak portion, can be formed to have a first distance value d1.

[0153] In the above configuration, the pressurized structure 72 can adjust the first height value h1 to effectively address the residual pressure difference, which varies depending on the viscosity or hardness of the contents.

[0154] Furthermore, the pressurized structure 72 can adjust the number of discharges and the discharge amount based on one cycle of 360-degree rotation by adjusting the first distance value d1, i.e., the angle value (circle reference). Based on one cycle, it can effectively deal with the residual pressure difference that changes according to the hardness by repeating the up-and-down motion multiple times. Here, the number of discharges and the discharge amount per discharge are defined as the pressurized projection 623 moving from the trough portion to the peak portion of the second wave shape of the second annular member 722, passing through to the next trough portion, while rotating and rising with the pressurized projection 623 inserted into the pressurized guideline of the pressurized structure 72.

[0155] Referring to Figure 7, in the other embodiment, the pressure structure 72 has the same first distance value d1 as the pressure structure 72 shown in Figure 6, where the distance between the valley portion of the second wave shape of the second annular member 722a and the adjacent valley portion, or between the peak portion and the adjacent peak portion, is the same. However, the distance between the peak portion and the valley portion of the first wave shape of the first annular member 721a and the third wave shape of the third annular member 723a is formed by a second height value h2, which has a larger difference than the first height value h1 of the pressure structure 72 shown in Figure 6.

[0156] Thus, in the other embodiments, the pressurized structure 72 has a second high / low value h2 that is greater than the first high / low value h1 of the pressurized structure 72, which increases the difference between the upward momentum and downward momentum of the head portion 71. The greater the downward momentum of the head portion 71, the greater the amount of residual pressure inside the container body 21 that dissipates.

[0157] Referring to Figure 8, in yet another embodiment, the pressurized structure 72b has the same first height-to-height value h1 as the pressurized structure 72 shown in Figure 6 between the peaks and valleys of the first wave shape of the first annular member 721b and the second wave shape of the third annular member 723b, but the distance between a valley of the first wave shape of the first annular member 721b or the second wave shape of the third annular member 723b and an adjacent valley or a peak and an adjacent peak is formed by a second distance value d2 which is smaller than the first distance value d1 of the pressurized structure 72 shown in Figure 6.

[0158] Thus, in other embodiments, the pressurized structure 72b has a second distance value d2 that is smaller than the first distance value d1 of the pressurized structure 72, so that the number of times the contents are dispensed increases and the amount of contents dispensed decreases during 360-degree rotation. That is, with a second distance value d2 that is smaller than the first distance value d1 of the pressurized structure 72, the cycle length is shortened, the number of times the contents are dispensed increases and the amount of contents dispensed decreases.

[0159] As described above, the greater the height difference between the peaks and troughs of the first and second waveform shapes, the greater the downward momentum of the head portion 71, thereby increasing the amount of residual pressure inside the container body 21 released. At this time, the height difference may be in the range of 0.25 mm to 1 mm, and specific dimensions such as 0.25 mm, 0.35 mm, 0.45 mm, and 0.45 + @ mm can be specified.

[0160] Furthermore, the pressurizing section 7 can be configured such that the smaller the distance between a trough of the first or second wave shape and an adjacent trough, or between a peak and an adjacent peak, the shorter the cycle period becomes, thereby increasing the number of times the contents are dispensed and decreasing the amount of contents dispensed relative to a 360-degree rotation. In this case, the angle value may be any one of 22.5 degrees, 45 degrees, and 90 degrees relative to one cycle, or, as will be described later, any one of 9 degrees and 18 degrees, but is not limited to these, and it goes without saying that a specific angle can be specified. The distance value is proportional to the angle value, and in this case, the distance value may be any one of 9 degrees, 18 degrees, 22.5 degrees, 45 degrees, and 90 degrees relative to one cycle, but is not limited to these.

[0161] Alternatively, in yet another embodiment, the pressurized structure 72b has a second distance value d2 that is smaller than the first distance value d1 of the pressurized structure 72, so that the number of discharges increases and the discharge amount decreases based on one cycle of 360-degree rotation.

[0162] As described above, the greater the difference in height between the peaks and troughs of the first and third waveform shapes of the pressurizing section 7, the greater the difference between the upward and downward momentum of the head section 71, thereby increasing the amount of residual pressure released. In this case, the height difference may be in the range of 0.25 mm to 1 mm, and may be any one of 0.25 mm, 0.8 mm, or 1 mm, but is not limited to these values.

[0163] Furthermore, the pressurizing section 7 can be configured such that the number of discharges increases and the discharge amount decreases based on one cycle (360-degree rotation) as the difference in distance between a trough of the second waveform shape and an adjacent trough, or between two adjacent peaks, decreases. In this case, the distance difference may be any one of 22.5 degrees, 45 degrees, and 90 degrees based on one cycle, but is not limited to these.

[0164] Figure 13 is a perspective view of a cosmetic container according to another embodiment of the present invention, Figure 14 is a first exploded perspective view of a cosmetic container according to another embodiment of the present invention, Figure 15 is a second exploded perspective view of a cosmetic container according to another embodiment of the present invention, and Figure 16 is a cross-sectional view of a cosmetic container according to another embodiment of the present invention.

[0165] Referring to Figures 13 to 16, a cosmetic container according to another embodiment of the present invention may be configured such that, while pressurizing the inside of the container body 21, the pressurizing means moves upward and downward alternately, increasing the internal pressure of the container body 21 by the upward movement to discharge the contents, and eliminating any remaining pressure in the container body 21 by the downward movement.

[0166] The cosmetic container of this embodiment may include an upper cover portion 1, a container portion 2, a lower cover portion 3, an intermediate portion 4, a shaft portion 5, an auxiliary portion 6, a pressurizing portion 7, and a fastening means 8.

[0167] In other embodiments of the present invention, the remaining components 1, 2, 3, 4, 5, 6, and 7, excluding the fastening means 8, are the same as those in each embodiment of the present invention described above, and the same reference numerals are used. Therefore, to avoid repetition in the explanation, a detailed explanation of each of the same components will be omitted here, and only the fastening means 8, which is a component that differs from the embodiment of the present invention, and the parts that change as a result will be explained.

[0168] The container portion 2 can be fastened to the upper cover portion 1 by the fastening means 8.

[0169] The fastening means 8 in this embodiment may include a fastening groove 81 provided along the inner circumferential surface of the upper cover portion 1, and a fastening projection 82 provided continuously or discontinuously along the outer circumferential surface of the container body 21, which is fastened to the fastening groove in a snap-on manner without horizontal restraint.

[0170] In the above configuration, when the lower cover portion 3 is rotated with the upper cover portion 1 fastened to the container portion 2, the fastening means 8 causes the lower cover portion 3 to rotate freely relative to the upper cover portion 1. As a result, the rotational force of the lower cover portion 3 is not transmitted to the shaft portion 5, thus preventing the contents from being discharged.

[0171] In this embodiment, the cosmetic container has the same size as the cosmetic container of the first embodiment described above, but the upper cover portion 1 and the intermediate portion 4 can be different.

[0172] In other words, the upper cover portion 1 of this embodiment can be made larger than the size (height) of the upper cover portion 1 of the above-described embodiment, and the intermediate portion 4 of this embodiment can be made smaller than the size (height) of the intermediate portion 4 of the above-described embodiment.

[0173] This embodiment achieves the objective of preventing the discharge of unwanted contents in addition to the fastening means 8 by increasing the size (height) of the upper cover portion 1, which allows the user to easily grasp the upper cover portion 1, which would otherwise rotate freely relative to the lower cover portion 3, while it is fastened to the container portion 2, and by decreasing the size (height) of the intermediate portion 4, which would otherwise rotate, making it difficult for the user to grasp the intermediate portion 4, which would otherwise rotate, while it is fastened to the container portion 2.

[0174] As described above, in one embodiment of the present invention or other embodiments, a cosmetic container can generate sound when the lower cover portion 3 is rotated to use the contents, due to the sound bar 24 of the container portion 2 and the sound projection 32 of the lower cover portion 3. In this case, sound is generated at regular intervals while the contents are being dispensed.

[0175] Furthermore, in one embodiment of the present invention or other embodiments of the cosmetic container, in addition to the sound bar 24 of the container part 2 and the sound projection 32 of the lower cover part 3 that generate sound, a pressurized structure part 72 may be provided so that when the lower cover part 3 etc. is rotated in order to use the contents, the pressurized part 7 rotates and rises, causing it to repeatedly perform an upward movement (one discharge of contents due to pressurization) and a downward movement (prevention of discharge of contents due to the disappearance of residual pressure). In this case, the sound can be generated at regular intervals regardless of the number of times the contents are discharged, or the sound can be generated in conjunction with the number of times the contents are discharged, as will be explained below with reference to Figure 17.

[0176] Figure 17 illustrates how sound is generated with each discharge of contents by adjusting the number or angle of the sound protrusions on the lower cover and the pressurized structure on the pressurized section.

[0177] Figure 17 shows the pressurized section 7, which is provided with the pressurized structure 72c, and the lower cover section 3, which is provided with the sound projection 32, in order to explain the relationship between the number of times the contents are dispensed and the sound.

[0178] The pressurized structure 72c may include a first annular member 721c having a first wave shape, a second annular member 722c, and a third annular member 723c having a second wave shape.

[0179] In the following, the relationship between the number of times the contents are dispensed and the sound will be explained with reference to Figure 17, in conjunction with one embodiment described with reference to Figures 1 to 12 and another embodiment described with reference to Figures 13 to 16.

[0180] In one embodiment or another embodiment, the cosmetic container is such that each time the pressurizing section 7 rotates on the first annular member 721c, passing through the peaks and valleys of the first wave-shaped section, one of the multiple sound protrusions 32 generates sound with a single friction with the sound bar 24.

[0181] In this case, the contents are discharged once while the pressurizing unit 7 moves from a peak to a valley (upward movement of the pressurizing unit 7) during one cycle of rotation, but not while it moves from a valley to another peak (downward movement of the pressurizing unit 7).

[0182] Table 1 shows the relationship between the number of times the contents are dispensed and the sound.

[0183] [Table 1]

[0184] Figure 17 shows the case in Table 1 above where the angle value of one cycle of the pressurizing section 7 is 18 degrees and the total number of sound protrusions 32 is 20. Referring to Table 1 above, the angle value of one cycle of the pressurizing section 7 may also be the value obtained by dividing 360 degrees by the total number of sound protrusions 32. It is preferable that the number of sound protrusions 32 is a multiple of 4. This makes the angle value an integer (or 22.5 degrees), which is a value that makes it easier to manufacture the container. That is, the angle value of one cycle of the pressurizing section 7 can correspond to the value obtained by dividing 360 degrees by a multiple of 4.

[0185] The number of sound protrusions 32 corresponds to the sum of the number of upward and downward movements of the pressurizing section 7 divided by 2, and they can be arranged at regular intervals on the inner surface of the lower cover section 3.

[0186] Furthermore, the angle values ​​of the multiple sound protrusions 32 can be such that the angle values ​​corresponding to one cycle of the pressurizing section 7 are arranged at regular intervals on the inner circumferential surface of the lower cover section 3.

[0187] Each of the multiple sound protrusions 32 may be arranged to correspond to a trough in the first waveform shape, as shown in Figure 7, which is the point at which the dispensing of the contents is completed once. This allows the user to confirm the number of times the contents have been dispensed by rotating the lower cover 3 or the like to use the contents, as one of the multiple sound protrusions 32 will pass through the sound bar 24 of the container 2 and generate sound. The point at which the sound is generated coincides with the point at which it passes through a trough in the first waveform shape.

[0188] The present invention has been described above, primarily focusing on embodiments. However, these are merely examples and do not limit the invention. Anyone with ordinary skill in the art to which the invention belongs will understand that various combinations, modifications, and applications not illustrated in the embodiments are possible, as long as they do not deviate from the essential technical content of these embodiments. Therefore, the technical content relating to modifications and applications that can be easily derived from the embodiments of the present invention should be interpreted as being included in the present invention.
