Description

Technical Field

[0001] This utility model relates to the field of lipstick design, and in particular to a replaceable lipstick container. Background Technology

[0002] Lipstick is a common cosmetic, mainly used to modify and enhance the color and texture of the lips. Because of its stickiness, lipstick is often packaged in a lipstick container to prevent it from accidentally transferring dirt or other contaminants, and to make it easier to use.

[0003] Most lipstick containers nowadays are equipped with a cup for holding lipstick. For example, ZL202421506436.3 discloses a lipstick container that includes an inner cylinder assembly with a receiving groove for holding lipstick makeup. The attached drawings show that the inner cylinder assembly includes a cup with the receiving groove on it.

[0004] However, the lipstick container's cup is not easy to disassemble after installation, making it difficult for users to switch between different lipstick colors, resulting in poor flexibility. Moreover, once the lipstick is used up, the container is often unusable and needs to be discarded, leading to resource waste.

[0005] On the other hand, in current lipstick containers, the material of the lipstick cup and the structure that comes into direct contact with the lipstick is often different from that of other structures. For example, the lipstick cup and related structures are made of PP material, while other structures are made of metal, ABS or POM material. This greatly increases the difficulty of subsequent sorting, recycling and reuse. Utility Model Content

[0006] The purpose of this invention is to provide a replaceable lipstick container that can solve one or more of the above-mentioned problems.

[0007] According to one aspect of the present invention, a replaceable lipstick container with a cup is provided, comprising a replaceable component, a central housing, a screw, a rotatable component, and a top cover assembly, wherein the replaceable component includes a cup and a central housing.

[0008] The middle beam and the rotatable component are rotatably connected relative to each other.

[0009] The screw includes a shaft and a cup holder connected to the shaft. The cup holder is slidably disposed within the central assembly. The shaft is connected to a rotatable component via a threaded connection.

[0010] The cup holder has a groove, and the inner wall of the groove has a first locking block. The cup is embedded in the groove and abuts against the first locking block.

[0011] The middle beam outer shell is snap-fitted onto the middle beam. The middle beam outer shell has a through hole, and the inner wall of the through hole has a protrusion. The material cup can abut against the protrusion.

[0012] The top cover assembly is detachably connected to the rotatable assembly and covers the middle housing.

[0013] The beneficial effects of this utility model are as follows: The material cup can be used to hold lipstick. Users can rotate the rotatable component, causing the screw to move linearly, thus controlling the amount of lipstick exposed and facilitating lipstick use. The replaceable component can be disassembled and replaced, and the protrusions allow the inner shell and material cup to move together, enabling them to be replaced as a whole. Direct replacement of the replaceable component facilitates the replacement of new lipsticks or different colors, allowing for multiple reuses of other structures in the lipstick container besides the replaceable component. This reduces waste generation, improves resource utilization, and also facilitates efficient sorting and recycling, even if the replaceable component and other structures are made of different materials. This reduces the difficulty of sorting, recycling, and reuse.

[0014] In some embodiments, a second locking block is provided around the periphery of the cup, and the second locking block is engaged with the inner wall of the groove. The provision of the second locking block can further improve the reliability of the cup's fixation on the cup holder.

[0015] In some embodiments, the outer periphery of the mid-beam has multiple protrusions, and the inner wall of the through hole has a slot, with the multiple protrusions abutting against the slot. The protrusions and slots enable the mid-beam housing to be snapped onto the mid-beam, effectively ensuring the mid-beam housing is fixed to the mid-beam.

[0016] In some embodiments, the rotatable component includes a nut, a base, and an inner bottom. The inner bottom is embedded within the base and fitted onto the nut. The nut has a groove with an internal thread, and the rod has an external thread. The internal and external threads are connected by a threaded engagement. The user can rotate the nut by rotating the base.

[0017] In some embodiments, a partition block is provided within the middle beam, dividing the middle beam into a first groove and a second groove. The cup holder is disposed in the first groove, and the rod passes through the partition block and extends into the second groove. The partition block facilitates the positioning of the rod, while the first groove limits the cup holder to reduce unexpected movement of the cup holder.

[0018] In some embodiments, a slider is provided around the periphery of the cup holder, and the slider is slidably disposed on the inner wall of the first groove. Thus, the cup holder can slide along the first groove.

[0019] In some embodiments, the second groove has a recess, and the rotatable component has a protrusion. The rotatable component extends into the second groove, and the protrusion is rotatably disposed on the recess. The recess and protrusion can position the rotatable component on the center beam, ensuring the accuracy of the rotatable component's position on the center beam. At the same time, they can increase the contact area between the rotatable component and the center beam, improving the reliability of the connection between the rotatable component and the center beam.

[0020] In some embodiments, the top cover assembly includes an outer cover, an inner cover, and a weight. The weight is embedded in the inner cover, and the outer cover is fitted over the inner cover, covering the weight. The weight ensures that the top cover assembly has sufficient weight, thereby increasing the friction between the top cover assembly and the placement surface after disassembly, thus reducing the probability of the top cover assembly being accidentally moved or lost.

[0021] In some embodiments, the material cup has a lipstick-containing cavity, and an annular protrusion is provided around the periphery of the material cup. The annular protrusion has an annular groove, and when the material cup abuts against the protrusion, the protrusion is embedded within the annular groove. The annular groove improves the connection reliability between the material cup and the protrusion when they abut, reducing the possibility of misalignment of the material cup.

[0022] In some embodiments, a second locking block is provided around the periphery of the material cup, and the second locking block is engaged with the material cup holder. The second locking block ensures that the material cup can be effectively fixed on the material cup holder, and also allows the user to easily apply force to separate the material cup and the material cup holder.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 This utility model discloses a replaceable lipstick container with a cup, comprising a replaceable component, a central hub 2, a screw 4, a rotatable component 5, and a top cover component 6. The replaceable component includes a cup 1 and a central hub shell 3. Furthermore, the replaceable component can be made of different materials than the other structures; preferably, the replaceable component can be made of PP material, while the other structures can be made of ABS material.

[0034] The rotatable component 5 includes a nut 51, a base 52, and an inner bottom 53. The inner bottom 53 is fitted into the base 52 by a snap-fit, and the inner bottom 53 is fixedly sleeved on the outer side of the nut 51 by a snap-fit, so that the nut 51, the base 52, and the inner bottom 53 can move together, that is, the nut 51 can rotate as the base 52 rotates through the inner bottom 53.

[0035] The nut 51 has a groove 511 inside, and the inner wall of the groove 511 has an internal thread 512. The nut 51 of the rotatable component 5 also has a protrusion 513 on its outer periphery.

[0036] The middle beam 2 is provided with a partition 21, which divides the middle beam 2 into a first groove 22 and a second groove 23. The second groove 23 is provided with a recess 231, which is annular. The nut 51 of the rotatable component 5 extends into the second groove 23, and the protrusion 513 is rotatably embedded in the recess 231, so that the middle beam 2 is sleeved on the rotatable component 1, and the middle beam 2 and the rotatable component 1 can rotate relative to each other.

[0037] The mid-beam housing 3 is detachably and fixedly fitted onto the mid-beam 2. Preferably, the mid-beam housing 3 has a through hole 31 inside, and the mid-beam 2 has a plurality of protrusions 24 on its outer periphery. The inner wall of the through hole 31 also has a slot 312. The plurality of protrusions 24 abut against the slot 312 on the inner wall of the through hole 31, thereby fixing the mid-beam housing 3 onto the mid-beam 2. The user can apply force to separate the protrusions 24 from the slot 312 to remove the mid-beam housing 3 from the mid-beam 2.

[0038] The inner wall of the through hole 31 of the middle beam housing 3 is also provided with a protrusion 311. When the middle beam housing 3 is fitted onto the middle beam 2, the protrusion 311 can abut against the end of the middle beam 2.

[0039] The screw 4 includes a shaft 41 and a cup holder 42. One end of the shaft 41 is integrally connected to the bottom end of the cup holder 42.

[0040] The cup holder 42 is slidably disposed in the first groove 22 of the middle bundle 2. Preferably, the outer periphery of the cup holder 42 is provided with a plurality of sliders 421, and the inner wall of the first groove 22 is also provided with a plurality of sliding grooves. The plurality of sliders 421 are slidably disposed one-to-one on the sliding grooves of the plurality of first grooves 22, so that the cup holder 42 can slide along the sliding grooves.

[0041] The rod 41 passes through the partition 21 and extends into the second groove 23. The outer periphery of the part of the rod 41 that passes through the partition 21 is provided with an external thread 411. The external thread 411 and the internal thread 512 in the groove 511 of the nut 51 are connected by a threaded engagement, thereby connecting the rod 41 and the rotatable component 5.

[0042] The cup 1 has a lipstick-containing cavity 11 in the middle, and the cup holder 42 has a groove 422 in the middle. The cup 1 is detachably embedded in the groove of the cup holder 42. Preferably, the inner wall of the groove 422 is provided with a plurality of first locking blocks 423. The outer periphery of the cup 1 can abut against the first locking blocks 423 to achieve the locking of the cup 1 and the cup holder 42. At the same time, the outer periphery of the cup 1 can also be provided with second locking blocks 14. There can be multiple second locking blocks 14, which are locked on the inner wall of the groove 422 of the cup holder 42 to further improve the fixing reliability of the cup 1 on the cup holder 42. In addition, the user can apply force to dislodge the second locking blocks 14 from the inner wall of the groove 422 of the cup holder 42, thereby realizing the disassembly of the cup 1.

[0043] The material cup 1 can abut against the protrusion 311. Preferably, the material cup 1 is also provided with an annular protrusion 12 on its periphery. The bottom of the annular protrusion 12 is provided with an annular groove 13. The annular protrusion 12 of the material cup 1 can abut against the protrusion 311 of the middle bundle shell 3, and at this time the protrusion 311 can be embedded in the annular groove 13.

[0044] The upper cover assembly 6 includes an outer cover 61, an inner cover 62, and a weight 63. The weight 63 is fixedly embedded in the inner cover 62, and the outer cover 61 is fixedly sleeved on the inner cover 62, covering the weight 63, so that the weight 63 can be positioned between the inner cover 62 and the outer cover 61, and the weight 63 can be hidden by the inner cover 62 and the outer cover 61.

[0045] The upper cover assembly 6 is detachably connected to the rotatable assembly 5. Preferably, the inner cover 62 of the upper cover assembly 6 has a groove, and the base 52 of the rotatable assembly 5 has a locking block that can engage with the groove, thereby connecting the upper cover assembly 6 to the base 52. The user can apply force to disengage the locking block from the groove, thus detaching the upper cover assembly 6. After the upper cover assembly 6 is connected to the rotatable assembly 5, the inner cover 62 can cover the middle housing 3.

[0046] When in use, the replaceable lipstick container holds lipstick in a fixed position on the lipstick cavity 11. Normally, the cup 1 rests on the protrusion 311, and the top cover assembly 6 is connected to the rotatable assembly 5, allowing the lipstick in the lipstick cavity 11 to be hidden and protected by the top cover assembly 6. In this state, the lipstick, along with the replaceable lipstick container, can be easily carried and moved.

[0047] When a user needs to use the lipstick, they can apply force to separate the top cover assembly 6 and the rotatable assembly 5, exposing the lipstick. By rotating the base 52, the user can cause the nut 51 to rotate via the inner bottom 53. The screw 4, which is threadedly engaged with the nut 51, can only move linearly due to the constraint of the middle beam 2. As the nut 51 rotates, the material cup seat 42 of the screw 4 will move linearly within the first groove 22 of the middle beam 2. That is, the material cup 1 connected to the material cup seat 42 can move accordingly, and the lipstick on the material cup 1 can also move accordingly. This adjusts the position of the lipstick and thus the amount of lipstick exposed to suit different user needs.

[0048] When the lipstick in the cup 1 is used up, or when the user wants to change to a different lipstick color, or when the lipstick container needs to be sorted and recycled, the user can separate the replaceable component by applying force. Preferably, the force is applied to separate the protrusion 24 from the slot 312, so that the middle bundle shell 3 can move relative to the middle bundle 2 to separate. As the middle bundle shell 3 moves, the cup 1 will abut against the protrusion 311, which will move the cup 1 together, so that the cup 1 can move relative to the cup holder 42 to separate. Finally, the cup 1 and the middle bundle shell 3 are separated from other structures.

[0049] At this point, the separated middle beam shell 3 and the material cup 1 can be recycled as a whole, while the remaining structures can be recycled separately.

[0050] In addition, the rest of the structure can also be reused by installing the replacement components. Preferably, the cup 1 on the replacement component can be loaded with a new cup 1 containing a complete lipstick or a lipstick of a different color. The middle shell 3 is reconnected to the middle 2, and the new cup 1 is connected to the cup holder 42. Then the lipstick container with the new lipstick can be reused.

[0051] The material cup 1 and the inner shell 3 in this lipstick container are designed to be replaceable, which allows most of the components in the lipstick container to be reused, reducing waste generation, improving resource utilization, and facilitating the classification and recycling of replaceable components of different materials and other components, effectively reducing the difficulty of classification and recycling.

[0052] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
