Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging box technology, and in particular to a loose powder cosmetic box. Background Technology

[0002] Loose powder and pressed powder are common cosmetics, usually packaged individually in lidded boxes. Most existing loose powder cosmetic boxes consist of a box body and a lid. Loose powder or pressed powder is used to set makeup effectively. To extend the lifespan of cosmetics, an inner liner is often installed inside the box. The cosmetics are placed in the inner liner, which also contains a mesh cloth and aluminum foil. The mesh cloth dispenses the powder, and the aluminum foil provides a seal. To further enhance the seal, the inner liner often has a flip-top. To use, simply open the lid and then open the flip-top.

[0003] In the prior art, a soft plastic mesh, a first shell, and a second shell are provided inside the cosmetic box. The first shell adopts a separate design of an outer frame and an inner support frame. The soft plastic mesh is fixed by embedding its peripheral area between the outer frame and the inner support frame of the first shell. The inner side of the outer frame has an outer pressure part with stepped protrusions, and the inner support frame extends to provide an inner pressure part. During assembly, after the peripheral area of ​​the soft plastic mesh is inserted into the annular groove of the outer frame structure, multiple bending clamps are formed by the misalignment and compression of the inner and outer pressure parts. The peripheral area preferentially generates elastic deformation when under pressure, and the deformation rebound force and the frame structure provide a limiting effect. At the same time, the second shell has a protrusion that can be embedded in the groove in the first shell to complete the overall positioning.

[0004] However, the existing technology has the following drawbacks: First, its first shell adopts a split outer frame and inner support design, which requires multi-stage extrusion to fix the soft rubber mesh through stepped outer pressure part, inner pressure part and annular groove. Although it can fix the soft rubber mesh to a certain extent, the structure is complex, the number of parts is large and the assembly precision requirements are high, resulting in high production costs. Second, the soft rubber mesh will be frequently pressed during use, and the soft rubber mesh of the existing technology only relies on the elastic clamping of the frame for fixation, lacking a limiting structure, which leads to unstable assembly. It is easy to loosen or even fall off during use, affecting the sealing performance of the cosmetic box. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a loose powder cosmetic box, thereby overcoming the deficiencies in the background technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a loose powder cosmetic box, comprising an outer box assembly and an inner box assembly assembled in the outer box assembly. A storage cavity for placing powder cosmetics is formed between the bottom of the outer box assembly and the inner box assembly. The inner box assembly includes an inner shell, an annular component, and an elastic component. The elastic component has several sets of powder dispensing parts for discharging powder cosmetics from the storage cavity. The annular component is snap-fitted to the lower part of the inner shell. A first assembly groove is provided at one end of the annular component facing the inner shell. The elastic component is fixedly assembled between the bottom wall of the first assembly groove and the inner shell. The inner shell has a first opening communicating with the elastic component. The inner diameter of the first opening is smaller than the inner diameter of the first assembly groove. The annular component also has a first limiting strip. The first limiting strip protrudes from the bottom wall of the first assembly groove toward the inner shell. The first limiting strip has a flat portion and a sloped portion. The flat portion is located on the top wall of the first limiting strip and is used to support the elastic component. The sloped portion is located on the side wall of the first limiting strip and gradually slopes downward from the flat portion.

[0007] Wherein, the outer diameter of the elastic element is greater than the diameter of the first opening, and the outer diameter of the elastic element is greater than or equal to the inner diameter of the first assembly groove.

[0008] The outer diameter of the elastic element is 1 to 1.002 times the inner diameter of the first assembly groove.

[0009] The inner box assembly further includes an inner cover, which is hinged to the inner shell.

[0010] The inner shell has a second assembly groove at one end facing the annular component. The bottom wall of the first assembly groove has a limiting protrusion protruding towards the inner shell. The first limiting strip is disposed between the limiting protrusion and the opening of the annular component. The limiting protrusion is engaged with the inner wall of the second assembly groove.

[0011] The first limiting strip is provided in multiple sets, and the multiple sets of the first limiting strip are distributed at equal angles around the center of the elastic member.

[0012] Both ends of the first limiting strip extend to the side wall of the first assembly groove.

[0013] The elastic element is made of an elastic material, such as silicone.

[0014] The elastic element is circular.

[0015] The area of ​​the elastic element is larger than the area of ​​the opening of the annular element.

[0016] The inner shell has a fourth mounting groove on its inner sidewall, and the inner cover has a fourth mounting protrusion. When the inner cover is closed on the inner shell, the fourth mounting protrusion engages with the inner wall of the fourth mounting groove.

[0017] The width of the powder dispensing section is smaller than the particle size of the powder cosmetic. When the elastic element is pressed down, the elastic element undergoes elastic deformation, causing the powder dispensing section to open. At this time, the width of the powder dispensing section is larger than the particle size of the powder cosmetic.

[0018] The outer box assembly includes a shell, a fastener, and an outer cover. The outer cover is hinged to the shell, and the fastener is assembled in the shell for engaging the outer cover and the shell.

[0019] The inner shell is provided with a third assembly groove at one end facing the annular component, and the bottom wall of the outer shell is provided with a third assembly protrusion facing the annular component. The third assembly protrusion is snapped into the inner wall of the third assembly groove.

[0020] The outer shell has a fifth mounting groove on its top wall facing downwards, the fastener is mounted in the fifth mounting groove, the side wall of the fifth mounting groove has a fifth mounting protrusion facing the storage cavity, the side wall of the fastener has a fifth mounting hole, and the fifth mounting protrusion is mounted in the fifth mounting hole.

[0021] The inner wall of the buckle is provided with reinforcing ribs that protrude towards the storage cavity.

[0022] The bottom wall of the fifth assembly groove is provided with a fifth limiting strip protruding towards the annular part, and the inner wall of the buckle is provided with a fifth limiting block protruding towards the storage cavity. The fifth limiting block abuts against the fifth limiting strip.

[0023] The fastener has a protruding pressing part on the side away from the storage cavity, and a buffer groove is provided at the end of the fastener facing the storage cavity. When the pressing part is pushed, the pressing part deforms toward the buffer groove and is located in the buffer groove.

[0024] The pressing part is made of an elastic material, such as silicone.

[0025] The top wall of the fastener has a protruding fastening protrusion, and the inner side wall of the outer cover has a fastening groove. When the outer cover is closed on the fastener, the fastening protrusion engages with the inner wall of the fastening groove.

[0026] The bottom of the outer shell has an arc-shaped groove.

[0027] The device also includes a mirror fixing component and a mirror. The side wall of the mirror fixing component is provided with a sixth assembly groove, and the inner side wall of the outer cover is provided with a sixth assembly protrusion. The sixth assembly protrusion is engaged with the sixth assembly groove, and the mirror is installed between the mirror fixing component and the outer cover.

[0028] The depth of the first assembly groove is 1.42-1.44 times the thickness of the elastic element.

[0029] The angle between the inclined portion and the planar portion is 115°-120°.

[0030] The beneficial effects of this utility model are as follows: by setting an elastic element between the ring part and the inner shell, the snap-fit ​​assembly structure of the ring part and the inner shell presses the elastic element together, and at the same time, multiple sets of first limiting strips distributed at equal angles around the ring part are set to provide uniform clamping force to the elastic element that is squeezed in the middle of the snap-fit ​​assembly structure to prevent slippage or displacement, ensuring tight fit and significantly improving the assembly stability of the soft rubber parts.

[0031] By providing a flat portion on the top wall of the first limiting strip, a horizontal supporting surface can be formed on the edge of the elastic element in the assembled state. Combined with the annular structure of the first limiting strip distributed at equal angles along the center of the elastic element, uniform compression of the elastic element can be achieved. The design of the inclined portion provides a buffer space for the compression deformation of the elastic element, avoiding stress concentration caused by rigid compression. This structure prevents the elastic element from sliding or shifting laterally when compressed, further enhancing the assembly stability of the elastic element.

[0032] By designing the powder section on the surface of the elastic element to be narrower than the outer diameter of the loose powder particles in its natural state, a physical barrier layer is formed, which directly blocks the passive escape of loose powder due to gravity or vibration, preventing the waste of loose powder. When pressed, the gap opens to allow the loose powder to be taken out. After pressing, the elastic element automatically closes the gap through elastic rebound, preventing residual loose powder from falling into the storage cavity and affecting the quality of the remaining loose powder, significantly improving the sealing reliability of the inner box assembly before and after use.

[0049] Example: Figure 1-11As shown, a loose powder cosmetic box includes an outer box assembly 1 and an inner box assembly 2 assembled in the outer box assembly 1. A storage cavity 7 for holding powder cosmetics is formed between the bottom of the outer box assembly 1 and the inner box assembly 2. The inner box assembly 2 includes an inner shell 21, an annular member 22, and an elastic member 3. The elastic member 3 has several sets of powder dispensing parts 31 for discharging powder cosmetics from the storage cavity 7. The annular member 22 is snapped onto the lower part of the inner shell 21. One end of the annular member 22 facing the inner shell 21 has a first... An assembly groove 221 is provided, and the elastic element 3 is fixedly assembled between the bottom wall of the first assembly groove 221 and the inner shell 21. The inner shell 21 has a first opening 211 that communicates with the elastic element 3. The inner diameter of the first opening 211 is smaller than the inner diameter of the first assembly groove 221. By providing the first assembly groove 221 in the annular part 22, when the elastic element 3 is assembled between the inner shell 21 and the annular part 22, the edge of the elastic element 3 can be pressed into the first assembly groove 221, which facilitates the fitting of the elastic element 3 and improves the assembly stability.

[0050] Wherein, the outer diameter of the elastic element 3 is larger than the diameter of the first opening 211, and the outer diameter of the elastic element 3 is greater than or equal to the inner diameter of the first mounting groove 221. By setting the aforementioned dimensional relationship, the elastic element 3 can be stably mounted between the first mounting groove 221 and the inner shell 21.

[0051] Wherein, the inner diameter of the first assembly groove 221 is L3, and the range of L3 is 48.7mm-48.8mm. The outer diameter of the elastic member 3 is 1-1.002 times the inner diameter L3 of the first assembly groove 221, preferably 1.001 times. By limiting the ratio of the outer diameter of the elastic member 3 to the inner diameter L3 of the first assembly groove 221, it is convenient for the elastic member 3 to be fully assembled into the first assembly groove 221.

[0052] The inner box assembly 2 also includes an inner cover 23, which is hinged to the inner shell 21. By providing the inner cover 23 that is hinged to the inner shell 21, it is convenient to seal and open the inner shell 21.

[0053] The inner shell 21 has a second assembly groove 212 at one end facing the annular component 22. The bottom wall of the first assembly groove 221 has a limiting protrusion 2210 protruding towards the inner shell 21. The limiting protrusion 2210 is snapped onto the inner wall of the second assembly groove 212. By setting the limiting protrusion 2210 to snap onto the inner wall of the second assembly groove 212, the inner shell 21 and the annular component 22 are assembled, thereby facilitating the fixation of the annular component 22.

[0054] The annular component 22 is further provided with a first limiting strip 222. The first limiting strip 222 protrudes from the bottom wall of the first assembly groove 221 toward the inner shell 21. The first limiting strip 222 is disposed between the limiting protrusion 2210 and the opening of the annular component 22. Multiple sets of the first limiting strip 222 are provided, and the multiple sets of the first limiting strip 222 are distributed at equal angles around the center of the elastic component 3. By setting the first limiting strip 222, the part of the elastic component 3 that is fitted into the first assembly groove 221 is pressed, so that the elastic component 3 and the part located in the first assembly groove 221 deform, preventing slippage and improving the stability of the assembly of the elastic component 3.

[0055] Both ends of the first limiting strip 222 extend to the side wall of the first assembly groove 221.

[0056] The first limiting strip 222 is provided with a flat part 2221 and an inclined part 2222. The flat part 2221 is provided on the top wall of the first limiting strip 222 and is used to support the elastic member 3. The inclined part 2222 is provided on the side wall of the first limiting strip 222 and is gradually inclined downward from the flat part 2221. Through the provision of the flat part 2221 and the inclined part 2222, the elastic member 3 can be supported and a buffer space can be provided for the deformation of the elastic member 3.

[0057] The elastic element 3 is made of an elastic material, such as silicone.

[0058] The elastic element 3 is circular.

[0059] The area of ​​the elastic element 3 is larger than the area of ​​the opening of the annular element 22. By setting the area of ​​the elastic element 3 to be larger than the area of ​​the opening of the annular element 22, the elastic element 3 is prevented from falling into the storage cavity 7 and affecting the use effect.

[0060] The inner shell 21 has a fourth mounting groove 214 on its inner sidewall, and the inner cover 23 has a fourth mounting protrusion 231. When the inner cover 23 is closed on the inner shell 21, the fourth mounting protrusion 231 engages with the inner wall of the fourth mounting groove 214. By setting the fourth mounting protrusion 231 to engage with the inner wall of the fourth mounting groove 214, the inner shell 21 and the inner cover 23 are engaged, thereby improving the sealing effect of the inner box assembly 2.

[0061] The width of the powder dispensing section 31 is smaller than the particle size of the powder cosmetic. When the elastic member 3 is pressed down, the elastic member 3 undergoes elastic deformation, causing the powder dispensing section 31 to open. At this time, the width of the powder dispensing section 31 is larger than the particle size of the powder cosmetic, allowing the powder cosmetic to be discharged through the elastic member 3. When the elastic member 3 is not subjected to external force, i.e., it is not pressed, by setting the width of the powder dispensing section 31 to be smaller than the particle size of the powder cosmetic, the cosmetic will not overflow from the powder dispensing section 31, thereby playing a role in storing and sealing the powder cosmetic.

[0062] The outer box assembly 1 includes an outer shell 11, a fastener 4, and an outer cover 12. The outer cover 12 is hinged to the outer shell 11, and the fastener 4 is assembled in the outer shell 11 for engaging the outer cover 12 and the outer shell 11.

[0063] The inner shell 21 is provided with a third assembly groove 215 at one end facing the annular member 22. The bottom wall of the outer shell 11 is provided with a third assembly protrusion 111 facing the annular member 22. The third assembly protrusion 111 is snapped onto the inner wall of the third assembly groove 215. By setting the third assembly protrusion 111 to snap onto the inner wall of the third assembly groove 215, the assembly connection between the outer shell 11 and the inner shell 21 is realized.

[0064] The outer shell 11 has a fifth assembly groove 112 with its top wall facing downwards. The fastener 4 is assembled in the fifth assembly groove 112. The side wall of the fifth assembly groove 112 has a fifth assembly protrusion 113 facing the storage cavity 7. The side wall of the fastener 4 has a fifth assembly hole 41. The fifth assembly protrusion 113 is assembled in the fifth assembly hole 41. By setting the fifth assembly protrusion 113 and the fifth assembly hole 41, the assembly stability of the fastener 4 in the horizontal direction in the fifth assembly groove 112 is improved.

[0065] The inner wall of the buckle 4 is provided with reinforcing ribs 46 that protrude toward the storage cavity 7. By providing reinforcing ribs 46, the structural rigidity of the buckle 4 can be improved.

[0066] The bottom wall of the fifth assembly groove 112 is provided with a fifth limiting strip 117 protruding towards the annular part 22, and the inner wall of the buckle 4 is provided with a fifth limiting block 42 protruding towards the storage cavity 7. The fifth limiting block 42 abuts against the fifth limiting strip 117. By setting the fifth limiting strip 117 and the fifth limiting block 42 that abut against each other, the assembly stability of the buckle 4 in the horizontal direction in the fifth assembly groove 112 is further improved.

[0067] The buckle 4 has a protruding pressing part 44 on the side away from the storage cavity 7. The end of the buckle 4 facing the storage cavity 7 has a buffer groove 45. When the pressing part 44 is pushed, the pressing part 44 deforms towards the buffer groove 45 and is located in the buffer groove 45. The pressing part is arc-shaped. By setting the pressing part 44 and the buffer groove 45, it is convenient for the user to push the pressing part 44 inward, so that the pressing part 44 deforms through the buffer groove 45 and creates a gap in the fifth assembly groove 112, thereby making it easy to open the outer cover 12.

[0068] The pressing part 44 is made of an elastic material, such as silicone.

[0069] The top wall of the buckle 4 has a buckle protrusion 43, and the inner side wall of the outer cover 12 has a buckle groove 121. When the outer cover 12 is closed on the buckle 4, the buckle protrusion 43 is engaged with the inner wall of the buckle groove 121. The outer box assembly 1 can be sealed and opened by setting the buckle protrusion 43 and the buckle groove 121.

[0070] The bottom of the outer shell 11 is provided with an arc-shaped groove 114, which facilitates the fixing of the outer shell 11 during the assembly of the inner box assembly 2.

[0071] The system also includes a mirror fixing component 6 and a mirror 5. The mirror fixing component 6 has a sixth mounting groove 61 on its side wall, and the outer cover 12 has a sixth mounting protrusion 122 on its inner side wall. The sixth mounting protrusion 122 is engaged with the sixth mounting groove 61. The mirror 5 is installed between the mirror fixing component 6 and the outer cover 12. By placing the mirror 5 inside the outer cover 12, it is convenient for users to touch up their makeup in the mirror after opening the outer cover 12. After the mirror fixing component 6 is attached to the outer cover 12, it is convenient to fix the mirror 5 between the mirror fixing component 6 and the outer cover 12, preventing the mirror 5 from falling off during use. At the same time, the mirror fixing component 6 can be disassembled as needed to wipe or replace the mirror 5.

[0072] The depth of the first assembly groove 221 is L1, which ranges from 0.99mm to 1.01mm. The depth L1 of the first assembly groove 221 is 1.42 to 1.44 times the thickness of the elastic member 3, preferably 1.43 times. By limiting the ratio of the depth L1 of the first assembly groove 221 to the thickness of the elastic member 3, the clamping depth of the elastic member 3 can be ensured, and the assembly effect of the elastic member 3 in the first assembly groove 221 can be improved.

[0073] The angle between the inclined portion and the flat portion is α, which ranges from 115° to 120°. By limiting the inclination angle between the inclined portion and the flat portion, the clamping depth of the elastic member 3 is ensured, thereby improving the assembly effect of the elastic member 3 in the first assembly groove 221.

[0074] The depth of the second assembly groove 212 is L2, and the range of L2 is 1.48mm-1.52mm.

[0075] This embodiment provides a specific design dimension: the depth L1 of the first assembly groove 221 is 1 mm, the depth L2 of the second assembly groove 212 is 1.5 mm, the thickness of the elastic element 3 is 0.7 mm, the outer diameter of the elastic element 3 is 48.8 mm, the diameter of the first opening 211 is 44.7 mm, the inner diameter L3 of the first assembly groove 221 is 48.75 mm, the length of the powder outlet 31 is 2.2 mm, the width of the powder outlet 3 is 0.08 mm, and a is 117°.

[0076] The implementation principle of a loose powder cosmetic box in this embodiment is as follows: During use, the user pushes the pressing part 44 to release the assembly of the buckle protrusion 43 and the buckle groove 121, opening the outer shell 11 assembly. Then, the user flips the inner cover 23 to release the assembly of the fourth assembly protrusion 231 and the fourth assembly groove 214. Next, the user presses the surface of the elastic element 3. The elastic element 3 undergoes elastic deformation under vertical pressure, and the powder outlets 31 evenly distributed on its surface expand synchronously due to material stretching, forming a powder channel connecting the storage cavity 7 and the outside. At this time, the powdered cosmetic in the storage cavity 7, under the action of gravity and pressure difference, evenly seeps out along the expanded gap to the surface of the elastic element 3. When the pressure is released, the elastic element 3 quickly returns to its original shape due to the elastic recoil force of the elastic material, and the powder outlets 31 close to their initial width, which is smaller than the particle size of the powdered cosmetic, thoroughly... The bottom blockage prevents the powder from falling into the storage cavity 7 and contaminating the existing powder cosmetics. Combined with the first limiting strips 222 evenly distributed on the bottom wall of the first assembly groove 221, the flat part 2221 of the top wall is used to support the edge of the elastic member 3, and the inclined part 2222 of the side wall gradually slopes downward from the flat part 2221 to provide deformation buffer space. When the elastic member 3 is pressed, the flat part 2221 presses its edge to produce slight deformation, and the inclined part 2222 avoids stress concentration that could cause slippage. At the same time, the locking assembly of the limiting protrusion 2210 and the second assembly groove 212 provides an annular pressure equalization space for the edge of the elastic member 3, preventing the elastic member 3 from sliding and shifting, and achieving stable assembly of the elastic member 3 in the inner box assembly 2, thus preventing the elastic member 3 from falling off under the action of pressing.

[0077] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications and substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
