Description

Technical Field

[0001] This application relates to the field of cosmetic packaging technology, and in particular to a rotary dispensing cosmetic container. Background Technology

[0002] Most cosmetics commonly found on the market, such as lipsticks, cream blushes, and concealer pencils, use a twist-up design for dispensing. Users need to manually rotate the base or a specific rotating component to gradually reveal the product from the container. However, while this design considers the convenience of twist-up dispensing, it often has limitations. Specifically, due to design flaws in the container's internal structure, some product cannot be properly discharged from the nozzle near the bottom, resulting in approximately 5%-10% of the product remaining in the container and not being completely used. This not only wastes resources but may also negatively impact the consumer experience.

[0003] Therefore, the design flaws of cosmetic packaging during rotary dispensing urgently need to be addressed. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the purpose of this application is to solve the technical problem that the cream in the cosmetic container cannot be completely used up, resulting in resource waste.

[0005] To address the aforementioned issues, this application provides a rotary dispensing cosmetic container comprising a fork, beads, an ejector, and a spiral. The ejector supports the cream. Along a dispensing direction perpendicular to the cream, the beads, fork, and spiral are sequentially fitted over the ejector. One end of the spiral has an opening for the cream to extend and retract. A spiral track is provided on the inner wall of the spiral, spirally arranged along the dispensing direction of the cream. The ejector and beads pass through the fork and abut against the spiral track. The spiral drives the beads and the ejector to move along the spiral track.

[0006] When the bead moves to the end of the spiral track, the spiral rotates to move the ejector relative to the bead.

[0007] Preferably, a first guide is provided on the outer wall of the ejector, and a sliding channel is provided on the bead. The extending direction of the sliding channel is the same as the discharge direction of the paste. The first guide moves along the sliding channel so that the ejector drives the paste to move relative to the bead.

[0008] Preferably, the fork is provided with a guide channel, and the extending direction of the guide channel is the same as the discharge direction of the paste;

[0009] The outer wall of the bead is provided with a second guide member. The second guide member passes through the guide channel and is located in the spiral track. The first guide member passes through the sliding channel and the guide channel in sequence and is located in the spiral track. The spiral rotates to drive the bead and the ejector to move relative to the fork.

[0010] Preferably, the first guide is disposed at the end of the ejector that is away from the paste, and / or the second guide is disposed at the end of the bead that is close to the paste.

[0011] Preferably, the guide channel includes a first channel and a second channel, the first guide member passes through the first channel, the second guide member passes through the second channel, along the discharge direction of the paste, and the length of the first channel is equal to the sum of the length of the second channel and the length of the ejector member.

[0012] Preferably, the fork has a limiting channel connected to the second channel at both ends of its stroke in the second channel, and the limiting channel includes:

[0013] A first limiting channel is provided at one end of the second channel near the opening. The first limiting channel extends along a first direction on the outer wall of the fork. The first direction refers to the rotation direction of the fork when the ejector extends relative to the bead.

[0014] The second limiting channel is located at the end of the second channel away from the opening. The second limiting channel extends along a second direction on the outer wall of the fork. The second direction refers to the rotation direction of the fork when the ejector retracts relative to the bead.

[0015] Preferably, along the discharge direction of the paste, the first channel includes a first section, a second section, and a third section connected in sequence, the length of the first section being equal to the length of the ejector, and the length of the second channel being equal to the sum of the lengths of the second section and the third section;

[0016] Along the rotation direction of the fork, the cross-sectional dimensions of the first segment and the third segment are the same as the extension length of the limiting channel. The cross-sectional dimensions of the first segment and the third segment are both greater than the cross-sectional dimension of the second segment. The cross-sectional dimension of the second segment is equal to the cross-sectional dimension of the second channel.

[0017] Preferably, an axial limiting structure is provided between the bead and the ejector. When the bead moves to the end of its stroke, the second guide abuts against the limiting channel, and the ejector can overcome the resistance of the axial limiting structure and continue to move within the bead.

[0018] Preferably, the axial limiting structure includes a first locking member and a second locking member. The first locking member is disposed on the inner wall surface of the bead, and the second locking member is disposed on the outer wall surface of the ejector. The first locking member and the second locking member are offset. When the bead is located at the end of the stroke of the spiral track, the fork drives the second locking member to pass over the first locking member, so that the ejector drives the paste to move relative to the bead.

[0019] Preferably, there are two first guide members, which are symmetrically arranged on the outer wall surface of the ejector. The first channel corresponds to the first guide member, and at least one first channel extends to the end face of the fork facing the opening.

[0020] Preferably, the rotary dispensing cosmetic container further includes a base, the spiral is disposed inside the base, a fixing member is provided at the end of the fork away from the opening, a connecting member is provided on the inner wall surface of the base, the fixing member and the connecting member are connected, along the dispensing direction of the cream, the length of the spiral is greater than the length of the base, and the base can drive the fork to rotate relative to the spiral.

[0021] Based on the above technical solution, the rotary dispensing cosmetic container described in this application has the following beneficial effects:

[0022] By optimizing the rotary discharge design, specifically by incorporating an ejector inside the bead, the bead stops moving the paste relative to the opening once it reaches the end of the spiral path's stroke. Instead, the spiral continues to move the ejector relative to the opening, allowing it to either eject the paste from the bead or retract it. This ensures that the paste at the bottom of the bead is completely ejected during use, significantly reducing paste residue inside the bead. This improves paste utilization, reduces waste, and enhances the user experience.

[0023] Therefore, the rotary dispensing cosmetic container of this application achieves multiple technical effects, such as reducing cream residue, enhancing ease of use, improving product durability, and enhancing user experience, through the coordinated design of the spiral, fork, bead, and ejector.

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0043] like Figures 1-15 As shown in the figure, this embodiment discloses a rotary dispensing cosmetic container 100, which is used to hold creamy cosmetic materials, including lipsticks, water-light sticks, blush sticks, concealers, contouring creams, and other creams.

[0044] like Figure 2 , Figure 3 and Figure 5As shown, the rotary dispensing cosmetic container 100 includes a fork 200, a bead 300, an ejector 400, and a spiral 500.

[0045] The ejector 400 is used to support the paste. Along the discharge direction perpendicular to the paste, the bead 300, fork 200 and spiral 500 are sequentially sleeved on the ejector 400. That is, from the outside to the inside, the spiral 500, fork 200, bead 300 and ejector 400 are arranged in sequence. One end of the spiral 500 is provided with an opening 21 for the paste to extend and retract. The inner wall of the spiral 500 is provided with a spiral track 51. The spiral track 51 is spirally arranged along the discharge direction of the paste. The ejector 400 and bead 300 pass through the fork 200 and abut against the spiral track 51. The spiral 500 drives the bead 300 and ejector 400 to move along the spiral track 51.

[0046] Furthermore, the end of the ejector 400 facing the opening 21 can contact the paste. When the bead 300 is at the end of the stroke of the spiral track 51 facing the opening 21, the spiral 500 rotates to drive the ejector 400 to push the paste relative to the bead 300.

[0047] In the embodiments of this specification, the rotation of the screw 500 indicates that the screw 500 can rotate relative to the fork 200.

[0048] In the embodiments described in this specification, a positioning post 34 is provided on the bead 300 to limit and fix the paste.

[0049] In the embodiments described in this specification, the spiral 500, fork 200, bead 300 and ejector 400 are concentrically arranged, that is, the central axes of the four coincide.

[0050] In the embodiments described in this specification, the end of the journey of the spiral track 51 refers to the point at which the bead 300 reaches the end of the spiral track 51, and the bead 300 will no longer drive the paste to move relative to the opening 21.

[0051] In this embodiment, the discharge method is optimized by incorporating an ejector 400 inside the bead 300. When the bead 300 moves the paste to the end of the spiral track 51, it stops moving the paste relative to the opening 21. However, the spiral 500, via the fork 200, continues to move the ejector 400 relative to the opening 21, allowing the paste to continue moving. Therefore, during use, the ejector 400 can move relative to the bead 300, effectively ejecting the paste. This ensures that even the paste at the very bottom of the bead 300 is completely pushed out, significantly reducing paste residue within the bead 300. This improves paste utilization, reduces waste, and enhances the user experience.

[0052] Therefore, the rotary dispensing cosmetic container 100 of this application achieves multiple technical effects, such as reducing cream residue, enhancing ease of use, improving product durability, and enhancing user experience, through the coordinated design of the spiral 500, fork 200, bead 300 and ejector 400.

[0053] like Figures 11-13 As shown, a first guide member 42 is provided on the outer wall surface of the ejector 400, and a sliding channel 32 is provided on the bead 300. The extension direction of the sliding channel 32 is the same as the discharge direction X of the paste, that is, the extension direction of the sliding channel 32 is the same as the extension direction of the guide channel 22. The first guide member 42 can move within the sliding channel 32 so that the ejector 400 drives the paste to move relative to the bead 300.

[0054] In the embodiments of this specification, the first guide member 42 and the sliding channel 32 are configured so that the ejector member 400 can also move linearly along the setting direction of the sliding channel 32. That is, the movement of the first guide member 42 within the sliding channel 32 restricts the offset of the ejector member 400, so that the ejector member 400 can move precisely along the preset path of the sliding channel 32 when moving, ensuring that the ejector member 400 can accurately eject the paste along the discharge direction X of the paste.

[0055] like Figures 2-3 As shown, the fork 200 is provided with a guide channel 22, the extension direction of the guide channel 22 is the same as the discharge direction X of the paste; and the outer wall of the bead 300 is provided with a second guide member 33, the second guide member 33 can pass through the guide channel 22 and be connected to the spiral track 51, the first guide member 42 can pass through the sliding channel 32 and the guide channel 22 in sequence and be located in the spiral track 51. When the spiral 500 rotates, it can drive the ejector 400 to move relative to the bead 300. That is, the spiral 500 can rotate relative to the fork 200, causing both the bead 300 and the ejector 400 to move along the extension direction of the spiral track 51.

[0056] In the embodiments described in this specification, when the spiral 500 and the fork 200 move relative to each other, the first guide member 42 and the second guide member 33 can move synchronously within the guide channel 22 along the preset direction of the spiral track 51, providing precise guidance and coordination for the movement of the bead 300 and the ejector 400. In use, rotating either the fork 200 or the spiral 500 allows for precise discharge of the paste, simplifying the operation and improving user convenience.

[0057] like Figures 14-15 As shown, the first guide member 42 is disposed at the end of the ejector member 400 away from the paste, and, as Figures 11-13 As shown, the second guide 33 is disposed at the end of the bead 300 near the paste.

[0058] In the embodiments described in this specification, the first guide member 42 is disposed at the end of the ejector 400 away from the cream, so that the ejector 400 has a larger ejection stroke, which is equal to the length of the ejector 400. This ensures that even the cream at the bottom of the bead 300 can be completely ejected during the use of the rotating cosmetic container, thereby maximizing the utilization of the cream. Since the cream can be embedded in the bead 300, the second guide member 33 is disposed at the end of the bead 300 close to the cream, preferably in the middle section of the bead 300 and close to the cream. This allows some cream to remain in the bead 300 when the bead 300 pushes the cream out, providing good support for the bead 300 and preventing the cream from breaking due to complete extension, thus ensuring the integrity of the cream's shape and structure. Especially when the user accidentally ejects all the paste, there is still a large amount of unused paste inside the bead 300. Therefore, the remaining paste may tilt or break. The setting of the second guide 33 position can provide a stable base for the movement of the paste, so as to maintain the stability of the paste during the ejection process and prevent the paste from shifting or breaking during discharge.

[0059] Furthermore, the second guide member 33 is located at the end near the outlet 21, and there is a vertical height difference between it and the first guide member 42. Since they share a single spiral track 51, this avoids excessive longitudinal congestion and provides movement space for the first guide member 42. Additionally, by providing an ejector member 400 inside the bead 300, the ejector member 400 can push out any remaining paste inside the bead 300. Therefore, the coordinated arrangement of the second guide member 33 and the ejector member 400 achieves full utilization of the paste.

[0060] In other embodiments, the positions of the first guide 42 and the second guide 33 can be set as needed according to the material properties of the paste, the structural form of the paste, and the usage requirements of the rotary dispensing cosmetic container, so as to maintain the stability and integrity of the paste dispensing.

[0061] like Figures 8-10 As shown, the guide channel 22 includes a first channel 221 and a second channel 222. The first channel 221 is used for the first guide member 42 to move, and the second channel 222 is used for the second guide member 33 to move. Along the discharge direction X of the paste, the length of the first channel 221 is equal to the sum of the length of the second channel 222 and the length of the ejector member 400.

[0062] In the embodiments of this specification, since the first guide member 42 is located at the end of the ejector 400 away from the paste, that is, at the bottom end of the ejector 400, the length of the first channel 221 is set to be equal to the sum of the length of the second channel 222 and the length of the sliding channel 32. This ensures that when the bead 300 has reached the end of the stroke of the second channel 222 facing the opening 21, the ejector 400 still has extra space to continue moving upward, ensuring that even the bottom part of the paste can be completely ejected.

[0063] In the embodiments of this specification, the first channel 221 and the second channel 222 are designed based on the number and arrangement of the first guide member 42 and the second guide member 33, respectively. Therefore, in this embodiment, there are two first guide members 42 and two guide members 33. The two first guide members 42 are symmetrically arranged on the outer wall of the ejector 400 along the discharge direction X of the paste, and the two second guide members 33 are symmetrically arranged on the outer wall of the bead 300 along the discharge direction X of the paste. However, the first guide members 42 and the second guide members 33 do not overlap. Preferably, the two first guide members 42 and the two second guide members 33 are arranged alternately, and the distance between adjacent first guide members 42 and second guide members 33 is equal. Therefore, when there are two first channels 221 and two channels 222, the corresponding number and position of first guide members 42 and second guide members 33 are respectively provided. Alternatively, in other embodiments, there may be one first guide member 42 and one second guide member 33. When the ejector 400 is located inside the bead 300, the first guide member 42 and the second guide member 33 are symmetrically arranged relative to the discharge direction X of the paste, that is, the first channel 221 and the second channel 222 are symmetrically arranged on the fork 200 along the discharge direction X of the paste. The specific structural form of the first channel 221 and the second channel 222 can be set as needed according to the weight of the paste carried by the cosmetic and the material properties of the paste.

[0064] In the embodiments described in this specification, there are two first guide members 42, so the number and position of the first channels 221 correspond to the first guide members 42. Furthermore, at least one first channel 221 extends to the end face of the fork 200 facing the opening 21, meaning the second channel 222 communicates with the opening 21. This arrangement is intended to facilitate the assembly of the ejector 400, bead 300, fork 200, and spiral 500 together from the inside out.

[0065] like Figures 9-10 As shown, the fork 200 has a limiting channel connected to the second channel 222 at both ends of its stroke. The limiting channel includes a first limiting channel 231 and a second limiting channel 232. The stroke ends of the second channel 222 represent the two endpoints of the second channel 222.

[0066] The first limiting channel 231 is located at the end of the second channel 222 near the opening 21. The first limiting channel 231 extends along a first direction on the outer wall of the fork 200, which refers to the rotation direction of the fork 200 when the ejector 400 extends relative to the bead 300. The second limiting channel 232 is located at the end of the second channel 222 away from the opening 21. The second limiting channel 232 extends along a second direction on the outer wall of the fork 200, which refers to the rotation direction of the fork 200 when the ejector 400 retracts relative to the bead 300. That is, the extension direction of the first limiting channel 231 is opposite to the extension direction of the second limiting channel 232.

[0067] In the embodiments of this specification, the first limiting channel 231 is disposed at one end of the second channel 222 near the opening 21. When the bead 300 causes the paste to extend to its maximum extent relative to the opening 21, since the extension direction of the first limiting channel 231 is consistent with the rotation direction of the fork 200 when the ejector 400 extends, the first guide 42 will enter the first limiting channel 231 under the rotation of the fork 200, thereby limiting the bead 300. When the fork 200 continues to rotate in the same direction, it can drive the ejector 400 to continue to move in the first channel 221, so that the ejector 400 can eject the paste inside the bead 300. The second limiting channel 232 is located at the end of the second channel 222 away from the opening 21. When the bead 300 retracts relative to the opening 21 to the end of the stroke of the second channel 222 away from the opening 21, since the extension direction of the second limiting channel 232 is consistent with the rotation direction of the fork 200 when the ejector 400 retracts, the first guide 42 will enter the second limiting channel 232 under the reverse rotation of the fork 200, thereby limiting the bead 300. Since the first guide 42 is located at the end of the ejector 400 away from the paste, the first guide 42 will also move downward until the bottom of the first channel 221.

[0068] In the embodiments described in this specification, the design of the first limiting channel 231 and the second limiting channel 232 not only effectively prevents the bead 300 from over-extending or retracting, avoiding the paste from falling off the bead 300 due to over-extending, and providing a foundation for the ejector 400 to eject the paste from the bead 300, but also effectively prevents the paste from becoming unsmoothly ejected due to over-retraction. Simultaneously, the limiting channel design provides clear tactile feedback. When the second guide 33 enters the limiting channel, the user will feel a change in rotational resistance, thus knowing that the paste has reached its maximum extension or minimum retraction position, and accordingly adjusting the force of the rotating fork 200, enhancing the user's operational perception.

[0069] like Figures 9-10As shown, along the discharge direction X of the paste, the first channel 221 includes a first segment 2211, a second segment 2212 and a third segment 2213 connected in sequence. The end of the third segment 2213 facing the opening 21 is flush with the first limiting channel 231. The length of the first segment 2211 is equal to the length of the ejector 400. The length of the second channel 222 is equal to the sum of the lengths of the second segment 2212 and the third segment 2213.

[0070] Along the rotation direction of the fork 200, the cross-sectional dimensions of the first segment 2211 and the third segment 2213 are the same as the extension length of the limiting channel. The cross-sectional dimensions of the first segment 2211 and the third segment 2213 are both greater than the cross-sectional dimensions of the second segment 2212. The cross-sectional dimensions of the second segment 2212 are equal to the cross-sectional dimensions of the second channel 222.

[0071] In this embodiment, the total length of the second channel 222 is designed to be equal to the sum of the lengths of the second segment 2212 and the third segment 2213. Based on the first guide member 42 being located at the bottom of the ejector 400, this design ensures that when the bead 300 has reached the end of its travel on the guide channel 22 facing the opening 21, the ejector 400 still has additional space to continue moving towards the opening 21. This allows even the very bottom of the paste to be completely ejected, reducing paste residue inside the bead 300 and improving paste utilization. Furthermore, by designing the length of the first segment 2211 to be equal to the length of the ejector 400, it is ensured that the entire length of the ejector 400 can be accommodated within the first segment 2211 when the ejector 400 is in its maximum retracted position.

[0072] In the embodiments of this specification, based on the large cross-sectional dimensions of the first segment 2211 and the third segment 2213, which are the same as the extension length of the limiting channel, when the second guide member 33 of the bead 300 moves to the end of the stroke of the second channel 222 facing the opening 21, the continued rotation of the fork 200 can drive the second guide member 33 into the first limiting channel 231. At this time, the bead 300 can drive the ejector member 400 to rotate through the engagement of the first latching member 31 and the second latching member 41. That is, along the rotation direction of the fork 200, the length of the second guide member 33 moving in the second limiting channel 232 is equal to the length of the first guide member 42 moving in the first segment 2211 and the third segment 2213 of the first channel 221. This setting ensures that the first guide member 42 also has enough space to rotate, so as to facilitate the smooth ejection of the subsequent paste. Furthermore, when there is no need to stretch or contract the paste at the bottom of the bead 300, the second guide 33 will move normally within the second channel 222 without shifting relative to the second channel 222. Therefore, the first guide 42 and the second guide 33 will also not shift relative to the first channel 221. Thus, designing the middle stroke of the first channel 221, i.e., the second segment 2212, to have a cross-sectional dimension equal to that of the second channel 222 can further restrict the direction of movement of the first guide 42 while ensuring that it moves normally along the discharge direction X of the paste, so that the movement direction and speed of the first guide 42 and the second guide 33 are consistent.

[0073] In addition, an axial limiting structure is provided between the bead 300 and the ejector 400. When the bead 300 moves to the end of its stroke, the second guide 33 abuts against the limiting channel, and the ejector 400 can overcome the resistance of the axial limiting structure and continue to move within the bead 300.

[0074] Specifically, such as Figure 4 As shown, the axial limiting structure includes a first locking member 31 and a second locking member 41. The first locking member 31 is disposed on the inner wall surface of the bead 300, and the second locking member 41 is disposed on the outer wall surface of the ejector 400. The first locking member 31 and the second locking member 41 are staggered. When the bead 300 is located at the end of the stroke of the spiral track 51, the spiral 500 drives the second locking member 41 to pass over the first locking member 31, so that the ejector 400 drives the paste to move relative to the bead 300.

[0075] In the embodiments described in this specification, both the first snap-fit ​​member 31 and the second snap-fit ​​member 41 are protruding structures, staggered along the discharge direction X of the paste. In other embodiments, the structural form of the first snap-fit ​​member 31 and the second snap-fit ​​member 41, as well as their matching method, are not limited, as long as the ejector member 400 can drive the paste to move relative to the bead 300.

[0076] In the embodiments described in this specification, when the bead 300 reaches the end of its stroke in the guide channel 22, the continued rotation of the fork 200 causes the screw 500 to provide an upward force to the ejector 400, thereby causing the second locking member 41 to overcome the resistance of the first locking member 31 and move upward, achieving the effect of the ejector 400 moving within the bead 300. This structure effectively pushes the paste at the bottom of the bead 300 out relative to the opening 21, ensuring that the paste at the bottom of the bead 300 is fully utilized, avoiding the defect of paste residue in traditional designs where the paste is difficult to push out. Secondly, the design of the first clip 31 and the second clip 41 increases the interaction force between the ejector 400 and the bead 300. Before the bead 300 reaches its final stroke, the ejector 400 can move synchronously with the bead 300. After the bead 300 reaches its final stroke, the ejector 400 can continue to move along the spiral track, allowing the cream to move within the bead 300. Users only need to perform a simple rotation to completely and thoroughly eject the cream, without any other complicated operating steps. This simplifies the use of the rotating dispensing cosmetic container and improves the ease of operation.

[0077] Furthermore, such as Figure 5 and Figures 11-12 As shown, there are multiple second clips 41, which are arranged sequentially at intervals along the discharge direction X of the paste. Furthermore, along the discharge direction X of the paste, the cross-sectional dimensions of each second clip 41 are the same as those of the first clip 31.

[0078] In the embodiments of this specification, the second latching member 41 includes several columns, that is, several columns of the second latching member 41 are arranged sequentially and at intervals along the circumferential direction of the paste discharge. Each column contains multiple latching members, and the multiple second latching members 41 in each column are evenly arranged along the paste discharge direction X. This arrangement ensures that when the ejector 400 moves, the paste can be evenly pushed out by the ejector 400, achieving the effect of uniform paste discharge.

[0079] In the embodiments of this specification, multiple second locking members 41 are uniformly arranged along the discharge direction X of the paste. Since the cross-sectional dimensions of all second locking members 41 are the same as those of the first locking member 31, each second locking member 41 interacts with the first locking member 31 in the same way when the ejector 400 moves. Furthermore, the matching design of the first locking member 31 and the second locking member 41 allows for precise control of the movement of the ejector 400. Therefore, based on the linkage design of the fork 200 and the bead 300, the user can easily control the ejection speed and quantity of the paste, avoiding the inconvenience of ejecting too much paste at once in traditional rotary ejection methods, providing a consistent ejection effect, and ensuring that the paste is ejected uniformly and quantitatively. Simultaneously, the identical size of the first locking member 31 and the second locking member 41 ensures that the force at each point is the same when ejecting the paste, thus reducing potential malfunctions caused by size differences and enhancing product reliability. Furthermore, the engagement of the first locking member 31 and the second locking member 41 ensures that the user hears a "click-click" sound every time the fork 200 is turned. This allows the user to perceive the amount of rotation based on the sound, thus improving the user experience.

[0080] like Figures 2-3 As shown, the rotary dispensing cosmetic container also includes a base 600, a spiral 500 disposed inside the base 600, a fixing member 24 provided at the end of the fork 200 away from the opening 21, and a connecting member (not shown in the figure) provided on the inner wall surface of the base 600. The fixing member 24 can extend relative to the spiral 500, so that the fixing member and the connecting member are connected. Along the dispensing direction X of the cream, the length of the spiral 500 is greater than the length of the base 600, and the base 600 can drive the fork 200 to rotate relative to the spiral 500.

[0081] In the embodiments of this specification, the structural forms of the connectors and the fasteners correspond to each other. Preferably, there are multiple fasteners 24, which are arranged sequentially and at intervals along the circumferential direction of the paste discharge direction on the outer wall surface of the fork 200 away from the opening 21.

[0082] In the embodiments described in this specification, the fixing member 24 is a protruding structure, and a recessed structure adapted to the protruding structure is provided on the inner wall surface of the base 600, so that the fork 200 and the base 600 are fixed by the engagement of the protruding structure and the recessed structure. In other embodiments, the fixing member 24 may also be a recessed structure, and a protruding structure adapted to the recessed structure may be provided on the inner wall surface of the base 600, so that the fork 200 and the base 600 are fixed by the engagement of the protruding structure and the recessed structure.

[0083] In the embodiments described in this specification, the fork 200 and the base 600 are detachably connected, which facilitates the assembly and disassembly of the rotating cosmetic container. In other embodiments, the fork 200 and the base 600 can also be fixedly connected by other methods such as bonding or welding, which can be configured as needed.

[0084] In the embodiments described in this specification, since the fork 200 is fixedly connected to the base 600 via the fastener 24, rotating the base 600 can drive the fork 200 to rotate relative to the auger 500. Furthermore, since the length of the auger 500 is greater than the length of the base 600, during use, the user can hold the auger 500 with one hand and rotate the base 600 with the other hand, thereby enabling the paste inside the fork 200 to extend and retract relative to the opening 21. This simplifies the operation steps and improves user convenience and satisfaction.

[0085] like Figures 1-3 As shown, the rotary dispensing cosmetic container also includes a lid 700, which is located on the base 600. The lid 700 can cover the spiral 500 and the fork 200 inside. When the user needs to use it, he / she only needs to remove the lid 700 and rotate the base 600 to extend the cream for use.

[0086] like Figure 6 As shown below, the mechanism of use of the rotary dispensing cosmetic container of this application is described in detail:

[0087] like Figure 6 The diagram illustrates the positional changes of the internal components of the rotary dispensing cosmetic container during dispensing. When the base 600 rotates forward, the fixed connection between the base 600 and the fork 200 via the fixing member 24 causes the fork 200 to rotate synchronously. As the fork 200 rotates, the bead 300 and the ejector 400 rotate along the spiral track 51 of the spiral 500, causing the cream to move in the X direction and extend from the opening 21. When the first guide member 42 of the bead 300 reaches the end of its stroke on the spiral track 51 facing the opening 21, the fork 200 continues to rotate. The second guide member 33 enters the first limiting channel 231, preventing the bead 300 from continuing to move in the dispensing direction X. Meanwhile, the ejector 400 overcomes the damping force between the first and second locking members 31 and moves in the dispensing direction X, causing the cream to extend from the opening 21.

[0088] When the paste needs to be rotated back, the base 600 is rotated in the opposite direction. The bead 300 and the ejector 400 rotate simultaneously along the spiral track 51 of the spiral 500. The paste moves in the opposite direction of the X direction and retracts into the opening 21. When the bead 300 moves to the end of the stroke of the spiral track 51, the second guide 33 moves into the second limit channel 232. The bead 500 can no longer move. The base 600 is rotated in the opposite direction. The second locking member 41 passes over the first locking member 31, so that the ejector 400 moves in the opposite direction of the X direction within the bead 300, thereby realizing the reset of the bead 300 and the ejector 400.

Accordingly, the scope of the claims of this application is not limited to the foregoing specific embodiments.
