[0034] The present invention will now be further described with reference to the accompanying drawings and embodiments.

[0035] Figure 1 This is a schematic diagram of the overall structure of a packaging device for a replaceable cream-based cosmetic according to an embodiment of the present invention. Figure 2 This is an exploded structural diagram of a packaging device for a replaceable cream-type cosmetic according to an embodiment of the present invention.

[0036] Please refer to Figure 1 and Figure 2 The replaceable ointment cosmetic packaging device of the present invention includes a first box cover 1, a first box body 2 and a lifting mechanism 4; the first box body 2 has a first end 23 and a second end 24, and the first box cover 1 is fastened to the first end 23 of the first box body 2; the lifting mechanism 4 includes a base 45 and a lifting platform 41, the base 45 and the lifting platform 41 are movably connected, the base 45 is disposed at the second end 24 of the first box body 2, the lifting platform 41 is disposed inside the first box body 2, the lifting platform 41 can move closer to or away from the base 45, and the lifting mechanism 4 is detachably connected to the first box body 2.

[0037] Please refer to Figure 3The lifting mechanism 4 is a rotary lifting mechanism. The lifting platform 41 includes a base plate 42, a lifting platform body 413, and a boss 412. The bottom end of the lifting platform body 413 is connected to the base plate 42, and the top surface of the lifting platform body 413 is provided with a boss 412. Preferably, the lifting platform body 413 and the base plate 42 are detachably connected by plugging or snapping. Specifically, matching protrusions and slots can be provided on the lifting platform body 413 and the base plate 42 for snapping. The base plate 42 is provided with a first through hole 421, and a screw 44 is fixedly provided on the base 45. The first through hole 421 and the screw 441 are matched and connected. Specifically, there is a gap between the screw 441 and the first through hole 421, and the teeth mesh with each other. The screw 441 passes through the first through hole 421 and extends into the lifting platform body 41. When the base 45 rotates, it drives the screw 441 to rotate. The rotation of the screw 441 causes the base plate 42 to move along the screw 441, thereby moving the lifting platform 41 closer to or away from the base 45. In use, the movement position of the lifting platform 41 is controlled by rotating the base 45 clockwise or counterclockwise. Furthermore, at least one limiting piece 441 is provided at the top of the screw 441. The limiting piece 441 is engaged with the base plate 42 at the first through hole 421 to prevent the base plate 42 from detaching from the screw 441. In one specific embodiment, there are two limiting pieces 441, symmetrically arranged at the top of the screw 441, like an umbrella. Preferably, the limiting pieces 441 are integrally formed with the screw 441. Please refer to [link to relevant documentation]. Figure 4 In another embodiment, at least one barb 415 is also provided on the boss 412. The number of barbs 415 is preferably 2-16, and the barbs 415 are spaced apart on the circumference of the boss 412. More preferably, the barbs 415 are axially symmetrically distributed on the boss 412. When the boss 412 abuts against the bottom 32 of the replacement device 3, the barbs 415 can increase the frictional force between the boss 412 and the groove 321, preventing the bottom 32 of the box from falling during the lifting process of the lifting platform 412, and ensuring smooth movement of the bottom 32.

[0038] Further, please refer to Figure 2 and Figure 3The lifting mechanism 4 also includes a fixed sleeve 43, which has a bottom 432 and an open end 433. A base 45 is provided with a rotating platform 47, and the bottom of the screw 44 is fixed to the rotating platform 451. Preferably, the base 45, the rotating platform 47, and the screw 44 are integrally formed. The bottom 432 of the fixed sleeve 43 has a second through hole. The rotating platform 47 is provided with an inverted structure 471, which passes through the second through hole and is inverted onto the bottom 432 of the fixed sleeve 43. The base 45 can rotate relative to the fixed sleeve 43 via the rotating platform 451. The fixed sleeve 43 is fitted over the lifting platform 41, and the lifting platform 41 extends from the open end 433 of the fixed sleeve 43. Therefore, rotating the base 45 drives the rotating platform 47 and the screw 44 to rotate. Further, the fixed sleeve 43 includes a fixed sleeve body 434 and buttons 431 disposed on both sides of the fixed sleeve body 434. The buttons 431 are preferably protruding. Please refer to [reference needed]. Figure 5 A locking hole 221 is provided on the first housing 2 corresponding to the position of button 431. Button 431 is locked in the locking hole 221, making the first housing 2 and the lifting mechanism 4 detachably connected. Further, the first housing 2 includes an inner box 21 and an outer box 22. The outer box 22 is tightly attached to the outside of the inner box 21. The locking hole 431 is provided on both sides of the outer box 22. The inner box 22 has a relief groove 211 extending toward the second end 24 on the side corresponding to the position of the locking hole 221. In one embodiment, button 431 is made of elastic material. When an external force is applied to button 431, button 431 is fully inserted into the first housing 2 and slides out of the first housing 2 along the relief groove 211, separating the lifting mechanism 4 from the first housing 2. During installation, when button 431 slides along the relief groove 211 to the locking hole 221, it automatically returns to its original position due to its elasticity and is locked back in the locking hole 221. In another embodiment, a slot 435 is formed between the button 431 and the fixing sleeve body 434. When external force is applied, the button 431 can move and fully enter the first housing 2. At the same time, the lifting platform 41 has clearance holes 411 on both sides that match the button 431. When external force is applied to the button 431, the button 431 is located in the clearance hole 411, so that the button 431 is fully entered into the first housing 2. The button 431 slides out of the first housing 2 along the clearance groove 211, separating the lifting mechanism 4 from the first housing 2. During installation, when the button 431 slides along the clearance groove 211 to the locking hole 221, the button 431 automatically pops out from the clearance hole 411 due to its elasticity, returns to its original position, and is re-locked in the locking hole 221. Please refer to Figure 3 Furthermore, on both sides of the lifting platform 41, there are protrusions 414 between the clearance hole 411 and the base plate 42. The protrusions 414 are in contact with the button 431 or form a small gap. This can ensure that the lifting platform 41 does not shake during movement and remains stable. Secondly, it can ensure that the button 431 on the fixing sleeve 43 is not easily pressed down and accidentally detached from the first box body 2.

[0039] Please refer to Figure 3 , Figure 5 and Figure 6 In a preferred embodiment, a lid sleeve 11 is fitted onto the side wall 12 of the first lid 1, and a base sleeve 46 is fitted onto the outer side of the base 45. Preferably, the inner box 21, the first lid 1, and the lifting mechanism 4 are all made of plastic, while the outer box 22, the lid sleeve 11, and the base sleeve 46 are all made of aluminum alloy. Furthermore, secondary processing such as anodizing, spraying, printing, and laser engraving can be performed on the lid sleeve 11, the outer box 22, and the base sleeve 46 to make the product more textured and aesthetically pleasing.

[0040] The assembly process of the replaceable cream cosmetic packaging device provided in this embodiment of the invention includes: first, inserting the base plate 42 into the bottom of the lifting platform 41 for assembly and fixation; next, passing the rotating platform 451 on the base 45 through the second through hole on the bottom 432 of the fixing sleeve 43 and inverting it onto the bottom 432 to complete the assembly of the base 45 and the fixing sleeve 43, and the base 45 can rotate relative to the fixing sleeve 43 through the rotating platform 451; then, passing the screw 441 located in the rotating platform 451 through the first through hole on the base plate 42. Through the through hole 421, the lifting platform 41 is rotated to the bottom by rotating counterclockwise. At this time, the fixing sleeve 43 is fitted outside the lifting platform 41 and the lifting platform 41 extends from the open end 433 of the fixing sleeve 43, completing the assembly of the lifting mechanism 4. Then, the lifting mechanism 4 is pushed in from the second end 24 of the first box body 2, so that the buttons 431 on both sides of the fixing sleeve 43 slide along the relief groove 211 to the locking hole 221, fixing the lifting mechanism 4 inside the first box body 2. The first box cover 1 is then placed on the first end 23 of the first box body 2 to complete the assembly.

[0041] This embodiment does not impose any particular limitation on the specific shape of the packaging device; it can be box-shaped, bottle-shaped, or jar-shaped, etc., depending on the type of cream cosmetic or the required design shape. For example, a tube shape is chosen for lipstick, and a tube shape for body balm. Figure 1 As shown in the figure, the powder compact can be cylindrical or the same. As long as the packaging device structure provided by this invention is used so that the first box body 2 and the lifting mechanism 4 can be detachably connected, so as to facilitate the replacement of the replacement pack, and the lifting mechanism 4 can move the cosmetic cream in the replacement device 3, so that the packaging device can be reused.

[0042] Please refer to Figure 7 and Figure 8This embodiment also provides a replacement device for a cream-like cosmetic. The replacement device 3 can be used in conjunction with the aforementioned packaging device. The replacement device 3 includes a second box body 31 and a box bottom 32. The second box body 31 has a third end 311 and a fourth end 312. The box bottom 32 is detachably embedded in the fourth end 312 of the second box body 31, and the box bottom 32 can move along the inner wall of the second box body 31 toward the third end 311 of the second box body 31. The box body 31 and the box bottom 32 together form a box for holding the cosmetic cream. Further, the replacement device 3 also includes a second box cover 33, which is fastened to the second box body 31 and detachable from it. The second box cover protects the unused cosmetic cream in the replacement device 3 from contamination. The second box cover 33 can be, for example,... Figure 7 The outer cover shown can also be as follows: Figure 8 The embedded lid shown; since the replacement device 3 removes the second lid 33 during use, the second lid 33 should be detachably connected to the second box body 31. The removed second lid 33 can be discarded, or it can be fastened to the first end 23 of the first box body 2, and then the first lid 1 can be fastened, providing double protection for the cosmetic cream inside the replacement device 3. Furthermore, as... Figure 9 As shown, the top of the outer cover type second box lid 33 protrudes outward for easy opening, and the cosmetic cream shape formed by the inverted filling of the replacement device 3 through the box bottom 32 is more aesthetically pleasing. In a specific embodiment, the fourth end 312 of the second box body 31 extends inward to form a first flange. The first flange makes the opening size of the fourth end 312 of the second box body 31 smaller than the size of the box bottom 32. Therefore, the first flange embeds the box bottom 32 inside the second box body 31. In this embodiment, the second box body 31, the box bottom 32, and the second box lid 33 are all made of biodegradable materials. Furthermore, the second box body 31, the box bottom 32, and the second box lid 33 are all made of pulp die casting, which is environmentally friendly, biodegradable, and recyclable.

[0043] Please refer to Figure 10a , Figure 10b and Figure 10c The bottom of the box 32 is recessed towards the third end to form a groove 321. The shape and size of the groove 321 are similar to those of the box bottom 32. Figure 4 The shape and size of the boss 412 shown are matched, and the depth of the groove 321 is preferably 6-8mm, more preferably 6.5-7.5mm. The depth of the groove 321 refers to the height d of the groove 321 from the bottom to the top. Figure 10bAs shown. The groove with a relatively large depth d, especially in conjunction with the barb 415 on the boss, can increase the frictional force between the box bottom 32 and the boss 412. This solves the problem that the lifting platform 41 is prone to falling off due to insufficient frictional force between the box bottom 32 and the lifting platform 41 during the process of pushing the cosmetic up, and also allows the box bottom 32 and the cosmetic to move smoothly. In another embodiment, please refer to... Figure 10b and Figure 10c The bottom of the box 32 is provided with at least one third through hole 322, through which liquid cosmetic paste can be poured into the replacement device 3. Preferably, there are two third through holes 322, symmetrically located on both sides of the groove 321.

[0044] Please refer to Figure 11 This embodiment also provides a replaceable cream cosmetic, including the packaging device and the replacement device 3. The replacement device 3 contains a cosmetic cream (not shown in the figure). The fourth end 312 of the second box 31 is open and inserted into the first box 2. The third end 311 of the second box 31 is engaged with the first end 23 of the first box 2. The fourth end 312 of the second box 31 abuts against the end face of the open end 433 of the fixing sleeve 43, so that the second box 31 is fixed in the first box 2 and will not move. The top surface of the lifting platform 41 of the lifting mechanism 4 abuts against the bottom 32 of the replacement device 3. When the rotating base 45 moves the lifting platform 41 along the screw 44, it drives the cosmetic cream to move relative to the second box 31, so that the cosmetic cream is exposed at the first end 23 of the first box 2 for consumer use, or returned to the second box 31 for storage after use. Furthermore, the first end 23 of the first box body 2 extends inward to form a second flange 212. The second flange 212 makes the opening size of the first end 23 smaller than the opening size of the third end 311 of the second box body 31, thereby locking the third end 311 of the second box body 31 inside the first box body 2. This allows the lifting platform 41 to move only the cosmetic cream, while the second box body 31 remains stationary. Furthermore, the top surface of the lifting platform 41 has a protrusion 412. Correspondingly, the bottom 32 of the box has a groove 321 that matches the platform 412, so that the protrusion 412 abuts against the groove 321, preventing the cosmetic cream inside the second box body 31 from shaking or tilting, allowing the cosmetic cream to move smoothly.

[0045] The cream-like cosmetics described in this invention include, but are not limited to, body balms, lipsticks, cream-like lip glosses, eyeshadows, or pressed powders. As long as they are cream-like cosmetics, the packaging and replacement devices provided by this invention can be used.

[0046] The replaceable cream cosmetic provided by this invention includes the following process for changing the replacement packaging: 1. Rotate the base counterclockwise by 45 degrees to the bottom; 2. Press the button 431 at the card holes 221 on both sides of the first box body 2, so that the button 431 retracts into the clearance hole 411 and is completely inside the first box body 2. At the same time, hold the base 45 and pull it down. The button 431 slides out of the second end 24 of the first box body 2 along the clearance groove 211, so that the lifting mechanism 4 is disengaged from the first box body 2. 3. Remove the replacement device 3 after the cosmetic cream has been used up; 4. Take a new refill pack and remove the second box lid 33. The refill pack is the product after the cosmetic cream is put into the refill device 3. 5. The replacement assembly is installed inside the first box body 2, so that the third end 311 of the second box body 31 is engaged at the second flange 212 of the first end 23 of the first box body 2; 6. Then, insert the lifting mechanism 4, which was just separated, into the first box body 2 from the second end 24. The buttons 431 on both sides of the fixing sleeve 43 slide into the locking hole 221 along the relief groove 211, so that the lifting mechanism 2 is fixedly installed with the first box body 2. At this time, the fourth end 312 of the second box body 31 abuts against the open end of the fixing sleeve 43, and the protrusion 412 of the lifting platform 41 abuts against the groove 321 of the box bottom 32, thus completing the replacement of the replacement device. 7. Place the empty replacement device 3 into the recycling bin for degradation and recycling.

[0047] In summary, the replaceable cream-type cosmetic and its packaging and replacement device provided by this invention, by incorporating a detachably connected lifting mechanism and a first box body within the packaging device, and with the packaging device and replacement device working together, allows for reuse of the packaging device. After the lifting mechanism is disassembled, the old replacement device can be discarded, while a new replacement device containing cosmetic cream is inserted into the first box body. The base of the rotating lifting mechanism moves the lifting platform against the bottom of the replacement device's box to eject and retract the cosmetic cream, facilitating the use of the cream-type cosmetic. Furthermore, the replacement device is made of biodegradable and recyclable material, making it more environmentally friendly. Therefore, the replaceable cream-type cosmetic packaging device provided by this invention is reusable, significantly saving packaging materials and avoiding the serious environmental pollution caused by large-scale waste of packaging materials.
