Description

Technical Field

[0001] This invention relates to an applicator, and more particularly to a metal applicator for a cosmetic container. Background Technology

[0002] Most cosmetic containers that hold cosmetic liquid have an applicator fixed to them. The applicator is connected to the cosmetic container so that the cosmetic liquid flows out through the applicator. The applicator includes a connecting part and a dispensing part that is fixed to the connecting part.

[0003] Commercially available applicator applicators use the same material for both the contact part and the dispensing part, such as plastic, ceramic, or metal. If the applicator is made entirely of plastic, the product will look cheaper and will not reflect its value. If it is made entirely of ceramic or metal, the applicator and the cosmetic container cannot be precisely connected due to limitations in the processing technology.

[0004] In light of this, some manufacturers have adjusted the materials of the aforementioned applicator heads, using metal for the dispensing section and plastic for the connecting part, thus improving the problems. The dispensing section is made into a solid structure using powder metallurgy, and the metal dispensing section and the plastic connecting part are joined using a secondary injection molding (overmolding) method. Because the dimensions of the powder metallurgy dispensing section cannot perfectly match the connecting part, the surface of the joint is not smooth, and it lacks tensile strength, making it prone to breakage. Furthermore, to prevent leakage of cosmetic liquid, the dispensing holes are all located at the top, and a positioning post inside the outer cover is used to secure the dispensing holes to prevent leakage. This also limits the application area for the user.

[0005] Therefore, based on years of experience in manufacturing, developing and designing related products, the inventor, after detailed design and careful evaluation, finally arrived at this invention which is indeed practical. Summary of the Invention

[0045] Please see Figures 1 to 5The first embodiment of the present invention discloses a metal applicator for a cosmetic container, comprising:

[0046] A coating head 10 is formed by stamping a metal plate, so that the interior of the coating head 10 forms an accommodating space 14. A positioning post 11 is provided inside one end of the coating head 10. The positioning post 11 is connected to a positioning block 12. The connection between the positioning block 12 and the positioning post 11 forms a first abutting surface 121. A recessed edge 13 is provided at one end of the coating head 10 other than the positioning post 11.

[0047] A discharge part 20, made of plastic, is integrally formed from a connecting part 21, a discharge part 22, and a fitting part 23. The connecting part 21 is accommodated in the receiving space 14 of the applicator head 10. The top of the connecting part 21 has a through hole 211, and the connecting part 21 has a positioning opening 212 below the through hole 211. The positioning opening 212 communicates with the through hole 211, and a second abutment surface 213 is formed at the communication point. The positioning post 11 passes through the through hole 211, and the first abutting surface 121 abuts against the second abutting surface 213. The discharge part 22 is axially provided with a through groove 24. One end of the discharge part 22 extends with a flange 25, which is engaged with the concave flange 13 of the applicator head 10. The discharge part 22 is provided with a discharge hole 221 on one side, which is connected to the through groove 24. The inner wall surface of the fitting part 23 is provided with a rib 231, and a connecting ring 26 is provided inside it.

[0048] A piston rod 30 is formed by a flange disk 31 extending towards one end with a fixed section 32 and extending towards the other end with a rod body 33. The flange disk 31 has an annular groove 311 on its outer periphery, which is correspondingly embedded with the protruding rib 231 of the discharge member 20. The fixed section 32 is accommodated in the connecting ring 26. The outer surface of the fixed section 32 is surrounded by a limiting rib 321 near the flange disk 31, which abuts against the inner wall surface of the connecting ring 26. The outer surface of the rod body 33 is surrounded by a stop ring 331 near the flange disk 31. In addition, the piston rod 30 has an axially penetrating flow channel 34, which is connected to the through groove 24.

[0049] A bushing 40 has an axially formed receiving groove 41 at one end for accommodating the piston rod 30's rod body 33 and the stop ring 331. The bushing 40 has a cylindrical body 42 and an outer ring portion 43 connected to the cylindrical body 42. A circumferential portion 421 extends from one end edge of the cylindrical body 42, different from the outer ring portion 43. The circumferential portion 421 engages with the fitting portion 23 and the flange disc 31. The end faces abut against each other. The bottom of the outer ring portion 43 is provided with a conical ring protrusion 44. The end of the rod body 33, which is different from the flange disk 31, abuts against the ring protrusion 44. At least one feed port 431 is opened on the side of the outer ring portion 43. In addition, a limiting part 45 is provided on the inner wall surface of the bushing 40 at the connection between the cylinder body 42 and the outer ring portion 43. The limiting part 45 is engaged with the outer wall surface of the rod body 33.

[0050] An elastic element 50 is sleeved on the rod body 33 of the piston rod 30 and can move between the stop ring 331 and the limiting part 45.

[0051] See Figure 6 and Figure 7 As shown, the present invention is used in conjunction with an outer cap 60 and a bottle 70 containing cosmetic liquid. The outer cap 60 covers the applicator head 10 and the dispensing part 20. One end of the outer cap 60 has a threaded portion 61 on its inner wall surface and forms a pressing edge 62. The pressing edge 62 presses against the fitting portion 23 of the dispensing part 20. One end of the bottle 70 has an axially provided opening 71. The bushing 40 is fitted on the inner edge of the opening 71, so that the circumferential portion 421 abuts against the end face of the opening 71. The outer edge of the opening 71 has a threaded portion 72, which is threaded into the threaded portion 61 of the outer cap 60. In addition, the cosmetic liquid in the bottle 70 can flow into the flow channel 34 and the through groove 24 through the inlet 431.

[0052] Based on the above combination, see [link / reference] Figure 7 and Figure 8 As shown, when the user wants to use it, first unscrew the top cover 60. The stop ring 331 of the piston rod 30 is pushed by the elastic force of the elastic member 50, so that the rod body 33 moves away from the ring protrusion 44. The end face of the fitting part 23 and the flange plate 31 moves away from the circumferential part 421 of the bushing 40. At this time, the cosmetic liquid in the bottle body 70 flows into the flow channel 34 from each of the inlets 431, flows through the through groove 24 and then flows out from the outlet hole 221. It is used with the applicator head 10 to evenly apply it to the application area. Since the outlet hole 221 is located on the side of the outlet member 20, it can increase the application area of ​​the application area of ​​the user.

[0053] After use, tighten the outer cap 60 so that the threaded portion 72 of the bottle body 70 is screwed into the threaded portion 61 of the outer cap 60. At this time, the fitting portion 23 of the dispensing part 20 is pressed by the pressing flange 62 of the outer cap 60, so that the fitting portion 23 and the end face of the flange disc 31 abut against the circumferential portion 421 of the bushing 40, and the stop ring 331 compresses the elastic member 50. Thus, the rod 33 moves and abuts against the ring protrusion 44 to close the inlet 431, so that the cosmetic liquid in the bottle body 70 cannot flow out. Thus, through the action of the piston rod 30, the bushing 40 and the elastic member 50, not only can the cosmetic liquid flow out evenly and quantitatively, but it can also effectively prevent the cosmetic liquid from leaking out, achieve an airtight effect, and isolate the cosmetic liquid from air pollution.

[0054] It is worth mentioning that, see Figure 2 and Figure 5 The positioning post 11 of the applicator head 10 passes through the through hole 211 of the discharge part 20, and the first abutting surface 121 abuts against the second abutting surface 213. The flange 25 and the concave flange 13 are engaged accordingly. Due to the design of the corresponding structure and shape of the applicator head 10 and the discharge part 20, the applicator head 10 can be tightly combined with the discharge part 20. The applicator head 10 is made of metal plate by stamping, so that the receiving space 14 is formed inside the applicator head 10. Its dimensions can be made more precise, improving the tightness with the discharge part 20 and enhancing safety performance.

[0055] Continue reading Figure 9 As shown, this is the second embodiment of the present invention. The difference between the second and third embodiments is that the applicator 10 does not have the positioning post 11 and the positioning block 12, and the connecting part 21 of the discharge part 20 does not have the through hole 211 and the positioning opening 212. Instead, a groove 15 is recessed on the inner wall surface of the applicator 10 near the free end, and a slot 27 is axially formed in the middle position of the connecting part 21. A fixing rib 28 is circumferentially provided on the outer wall surface of the connecting part 21. The fixing rib 28 is correspondingly engaged with the groove 15, thereby allowing the applicator 10 to be tightly connected with the discharge part 20.

[0056] When the discharge part 20 is combined with the coating head 10, the joint part 21 will shrink inward in the direction of the groove 27 due to the setting of the groove 27, which can provide displacement space for the joint part 21, so that the fixing rib 28 can be more easily matched and engaged with the groove 15.

[0057] See also Figure 10As shown, this is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the applicator 10 does not have the groove 15, and the joint 21 does not have the slot 27 and the fixing rib 28. The applicator 10 and the discharge part 20 are combined by secondary injection molding. Since the applicator 10 is stamped from a metal plate, the accommodating space 14 is formed inside the applicator 10. Its dimensions can be made more precise, improving the tightness with the discharge part 20. After the combination, it will not cause unevenness on the outer surface of the discharge part 20.
