Description

Technical Field

[0001] This utility model relates to the field of dual-compartment container technology, specifically a roller-coated dual-compartment container. Background Technology

[0002] Cosmetic products, especially lotions, serums, and hair dyes that require on-site mixing, often need to have their two ingredients stored separately before use to prevent reactions that could affect their stability and efficacy during long-term storage. Current technology typically uses dual-compartment packaging containers, where the ingredients from both compartments are mixed before use to ensure freshness and activity.

[0003] In the existing technology, commonly used dual-compartment packaging containers include tubular type, dual-pump type, and press-mix type. However, in actual use, we have found that the above-mentioned traditional dual-compartment packaging containers generally have problems such as complicated operation and insufficient mixing, and are also difficult to apply to scenarios that require roller coating or uniform coating.

[0014] The end, inner cylinder, and vertical cylinder are constrained to a relatively non-rotatable state. The cylinder body can rotate relative to the end, inner cylinder, and vertical cylinder. As the cylinder body rotates, the vertical cylinder can move vertically downward in the inner cylinder and puncture the diaphragm by the puncturing blade, so that the material A in the storage cylinder can be mixed with the material B in the inner cylinder.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Example 1:

[0046] Please see Figures 1-5 This embodiment discloses a roller-coating type dual-compartment container, the main body of which is a cylindrical body 1, and the cylindrical body 1 has a cylindrical cavity 16.

[0047] like Figure 3 As shown, from bottom to top, there are a storage cylinder 8, an inner cylinder 2 and a vertical cylinder 19. The top of the storage cylinder 8 has an end 10, and the bottom of the inner cylinder 2 is inserted into the end 10 and sealed by a diaphragm 23. Thus, material A can be stored in the storage cylinder 8 and material B can be stored in the inner cylinder 2, with the two separated by the diaphragm 23.

[0048] To ensure a tight seal when the bottom of the inner cylinder 2 is inserted into the end 10, a raised sealing ring can be provided on the outer wall of the bottom of the inner cylinder 2. The sealing ring is in close contact with the inner wall of the end 10 to ensure a seal.

[0049] In this embodiment, the bottom end of the vertical cylinder 19 is inserted into the inner cylinder 2, and a piercing blade 22 is also provided at its bottom end. Thus, the vertical cylinder 19 is controlled to move downward, and the diaphragm 23 can be pierced by the piercing blade 22 so that material A and material B can be mixed.

[0050] To ensure a tight seal when the bottom of the vertical cylinder 19 is inserted into the inner cylinder 2, a raised sealing ring 21 can be provided on the outer wall of the bottom of the vertical cylinder 19. The sealing ring 21 is in close contact with the inner wall of the inner cylinder 2, thereby effectively ensuring the sealing effect.

[0051] The piercing head 22 preferably uses a triangular pointed blade structure, and a push plate is provided on the inner side of the blade, so that the vertical cylinder 19 can effectively cut and push the diaphragm 23 during the downward movement, ensuring that the piercing action is fast and thorough, and avoiding the problem of insufficient mixing caused by only partially breaking the diaphragm 23.

[0052] In this invention, the end 10, the inner cylinder 2, and the vertical cylinder 19 are constrained to a relatively non-rotatable state, while the cylinder 1 can rotate relative to the end 10, the inner cylinder 2, and the vertical cylinder 19. As the cylinder 1 rotates, the vertical cylinder 19 can move vertically downward in the inner cylinder 2 and puncture the diaphragm 23 by the puncturing blade 22, thereby mixing the material A in the storage cylinder 8 with the material B in the inner cylinder 2.

[0053] Specifically, such as Figure 3 and Figure 4 As shown, a stepped groove 7 is formed at the bottom of the cylindrical cavity 16 by expanding the diameter. The end 10 is inserted into the stepped groove 7, and at least one locking protrusion 12 is formed on the outer wall of the end 10. The locking protrusion 12 passes over the blocking protrusion 14 and is locked into the annular locking groove 13. The blocking protrusion 14 and the annular locking groove 13 are both provided on the inner wall of the stepped groove 7.

[0054] By engaging the locking protrusion 12 within the annular groove 13, the end 10 can be effectively prevented from dislodging from the stepped groove 7, providing axial limiting and ensuring a sealing effect. In addition, the cylinder 1 can also rotate freely relative to the end 10.

[0055] In this embodiment, a top cylinder 5 is provided at the top of the inner cylinder 2. The top cylinder 5 is inserted into the cylinder cavity 16. A skirt ring 3 is also formed on the outer wall of the bottom end of the top cylinder 5. A mating groove is formed between the skirt ring 3 and the inner cylinder 2 for inserting the top end of the end 10. A vertical positioning groove 4 is also provided on the skirt ring 3. A positioning protrusion 11 for inserting into the vertical positioning groove 4 is formed on the outer wall of the top end of the end 10. Thus, when the locking protrusion 12 is locked into the annular locking groove 13, the positioning protrusion 11 will also be locked into the vertical positioning groove 4. By locking the positioning protrusion 11 into the vertical positioning groove 4, the rotation of the inner cylinder 2 and the top cylinder 5 relative to the end 10 can be effectively restricted. At the same time, since the end 10 has been positioned by the locking protrusion 12, the inner cylinder 2 and the top cylinder 5 can also be effectively positioned in the cylinder cavity 16. The shoulder of the skirt ring 3 is just matched with the step groove 7 and the step of the cylinder cavity 16.

[0056] In addition, a limiting groove 6 is vertically opened on the top cylinder 5, and a sliding column 20 fixedly set on the outer wall of the vertical cylinder 19 is slidably set in the limiting groove 6. By sliding the sliding column 20 in the limiting groove 6, the relative rotation between the vertical cylinder 19 and the inner cylinder 2 can be restricted.

[0057] Therefore, the end 10, the inner cylinder 2, and the vertical cylinder 19 are restricted to being relatively non-rotatable, while the cylinder 1 can rotate relative to the end 10, the inner cylinder 2, and the vertical cylinder 19.

[0058] In this utility model, a cylinder head 9 is formed at the top of the cylinder body 1 with a reduced diameter. An insertion cylinder 24 is provided on the inner top wall of the cylinder head 9. An interlayer is formed between the cylinder head 9 and the insertion cylinder 24. The top of the vertical cylinder 19 is inserted into the interlayer, while the bottom of the insertion cylinder 24 is inserted into the vertical cylinder 19. In addition, a roller coating mechanism is installed at the center of the cylinder head 9.

[0059] The combination of the insertion tube 24, the vertical tube 19 and the inner tube 2 forms a sealed chamber, which facilitates the storage of material B. The roller coating mechanism facilitates the roller coating of the mixed material A and material B, allowing the mixed two materials to be directly and evenly applied, avoiding secondary transfer operations and significantly improving the convenience and application effect of cosmetics.

[0060] To ensure a tight seal when the bottom of the insertion cylinder 24 is inserted into the vertical cylinder 19, a raised sealing ring 25 can be provided on the outer wall of the bottom of the insertion cylinder 24. The sealing ring 25 is in close contact with the inner wall of the vertical cylinder 19, thereby effectively ensuring a tight seal.

[0061] like Figure 4As shown, a V-shaped groove 18 connected to the stepped groove 7 is also provided on the inner wall of the cylinder cavity 16. One side of the V-shaped groove 18 is vertical and the other side is inclined. The sliding column 20 is attached to the inclined side of the V-shaped groove 18. Thus, when the cylinder 1 rotates, the inclined surface of the V-shaped groove 18 can drive the sliding column 20 to move down in the limiting vertical groove 6, thereby causing the vertical cylinder 19 to move down. The downward movement of the vertical cylinder 19 punctures the diaphragm 23 through the piercing head 22, thereby enabling the material A and material B to mix.

[0062] In actual operation, the user holds the storage cylinder 8 with one hand (to restrict the rotation of the storage cylinder 8, inner cylinder 2 and vertical cylinder 19), and rotates the cylinder 1 with the other hand.

[0063] In this embodiment, a limiting groove 15 is also provided at the top of the top cylinder 5, and a limiting slider 17 is slidably provided in the limiting groove 15. The limiting slider 17 is fixedly provided on the inner top wall of the cylinder cavity 16. By sliding the limiting slider 17 in the limiting groove 15, the rotation stroke of the cylinder 1 can be limited.

[0064] Example 2:

[0065] Please see Figure 2 and Figure 6 Based on Embodiment 1, this embodiment specifically provides a roller coating mechanism, such as... Figure 6 As shown, the roller coating mechanism includes a roller coating nozzle 27 and a roller coating ball 29. The roller coating nozzle 27 is installed at the center of the cylinder head 9, and a ball groove 28 is opened at the top end that communicates with the cavity of the roller coating nozzle 27. The roller coating ball 29 is rotatably disposed in the ball groove 28 for rolling out material.

[0066] To ensure smooth material discharge, such as Figure 6 As shown, four liquid outlet channels 30 are evenly provided on the inner wall of the ball tank 28.

[0067] In this invention, an end cap 31 is screwed onto the cylinder head 9 to protect the coating mechanism when not in use. Figure 2 As shown, a sleeve 32 for fitting onto the top of the roller coating nozzle 27 is fixedly provided at the center of the inner top wall of the end cap 31. The bottom opening of the sleeve 32 has an outward flare 33. When the end cap 31 is screwed on, the sleeve 32 is pressed against the top of the roller coating nozzle 27 through the outward flare 33, thereby tightening the top of the roller coating nozzle 27 and making the top of the roller coating nozzle 27 tightly cover the roller coating ball 29, cutting off the liquid outlet channel 30, thereby ensuring the storage effect of material B in the storage state.

[0068] Example 3:

[0069] Please see Figure 3 and Figure 5Based on Embodiment 1 or Embodiment 2, in this embodiment, triangular extrusion plates 26 are evenly arranged in a ring on the inner top wall of the interlayer, and a fitting groove 34 that cooperates with the extrusion plates 26 is provided at the top of the vertical cylinder 19. When the cylinder 1 rotates, the extrusion plates 26 can squeeze the side wall of the fitting groove 34, thereby pushing the vertical cylinder 19 to move vertically downward.

[0070] The pushing structure of the extrusion plate 26, together with the pushing structure of the V-groove 18 in Embodiment 1, forms a double pushing structure, which ensures the stability and controllability of the vertical cylinder 19 during the downward movement process and effectively avoids problems such as skewing, jamming or incomplete puncture.

[0071] Preferably, the edges of the extrusion plates 26 are rounded to avoid local stress concentration on the vertical cylinder 19 during rotation; at the same time, the multiple extrusion plates 26 are evenly distributed in a ring, which can form a balanced force in the circumference of the vertical cylinder 19, making its downward movement more stable.

[0072] In actual use, the user holds the storage cylinder 8 with one hand (to keep the storage cylinder 8, inner cylinder 2 and vertical cylinder 19 fixed) and rotates the cylinder 1 with the other hand.

[0073] When the cylinder 1 rotates, the sliding column 20 set on the outer wall of the vertical cylinder 19 is gradually guided downward under the action of the inclined surface of the V-shaped groove 18. At the same time, the triangular extrusion plate 26 on the inner top wall of the interlayer also interacts with the fitting groove 34 at the top of the vertical cylinder 19, applying downward pressure to the vertical cylinder 19. The two form a double-push structure, which makes the vertical cylinder 19 move downward smoothly in the vertical direction.

[0074] As the vertical cylinder 19 moves downward, the piercing blade 22 at its bottom gradually contacts and pierces the diaphragm 23 at the bottom of the inner cylinder 2, thereby allowing the material B in the inner cylinder 2 to enter the storage cylinder 8 and mix with the original material A in the storage cylinder 8. Since the downward movement of the vertical cylinder 19 is continuous and controllable, the piercing action is also thorough and uniform.

[0075] After material A and material B are fully mixed, unscrew the end cap 31, invert the equipment, and the mixture flows down through the cavity of the vertical cylinder 19 and the insertion cylinder 24, and finally flows into the ball groove 28 through the roller coating nozzle 27 at the cylinder head 9. The roller coating ball 29 rotates freely during the user's coating operation, bringing out the mixed material and evenly coating it on the application area, thereby achieving uniform coating.

[0076] When not in use, the end cap 31 is screwed onto the cylinder head 9, and the sleeve 32 can press the top of the roller nozzle 27 tightly, thereby effectively preventing material leakage or volatilization and ensuring the safety and stability of material storage.

[0077] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
