Title of the invention: COSMETIC APPLICATOR STRUCTURE FIELD OF INVENTION

[0001] The present invention relates to a cosmetic applicator structure, and more particularly to a cosmetic applicator structure with a fixed applicator head. PREVIOUS STATE OF THE ART

[0002] A conventional cosmetic applicator structure (also called a cosmetic product applicator) comprises a support rod and an applicator head bonded to one end of the support rod. The applicator head is made of a spongy material. A hole is formed in the center of the applicator head. One end of the support rod is inserted into the hole and connected to the applicator head.

[0003] However, the conventional applicator head is attached to the support rod with glue, which causes environmental pollution and disregards the concept of environmental protection. The adhesive effectiveness of the glue is affected by its incompatibility with certain chemical agents (cosmetic lotions), which can lead to the applicator head dislocating or separating from the support rod. The applicator head is bonded to the support rod with glue, which reduces its tensile strength. Furthermore, because a hole is formed in the applicator head, the overall structure of the applicator head is damaged, thus reducing its service life.

[0004] Consequently, the inventor of the present invention has sought to solve these problems by drawing upon his many years of practical experience. Summary of the invention

One end of the support rod has a positioning section. The positioning section has a positioning hole. An inner wall of the positioning hole has a recess. The recess has an engagement surface. The connecting element is in a snap-fit ​​position with the positioning hole of the support rod. The connecting element has an axially extending locking orifice. The connecting element has a circumferential portion formed on an edge of one of its ends. The circumferential portion is attached to an end edge of the section Positioning. An annular flange is placed on an outer wall of the connecting element. The upper and lower sides of the annular flange have a locking surface and an inclined surface. The annular flange engages with the recess. The locking surface engages with the engagement surface. The applicator head is connected by insertion to the locking hole of the connecting element. A lower portion of the applicator head has a projecting annular portion. The projecting annular portion is inserted through the connecting element and extends from another end of the connecting element opposite the circumferential portion.

[0006] Advantageously, a groove is formed in a lower part of the positioning hole, and the protruding annular part is partially received in the groove.

[0007] Advantageously, the protruding annular part has a diameter greater than that of the locking orifice.

[0008] Advantageously, another end of the support rod has a coupling section, and the coupling section is configured to connect to a lid of a cosmetic container.

[0021] DETAILED DESCRIPTION OF PREFERRED EMBODIMENT MODES

[0022] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0023] As illustrated from [Fig.1] to [Fig.4], the present invention discloses a cosmetic applicator structure 100, comprising a support rod 10, a connecting element 20, and an applicator head 30.

[0024] One end of the support rod 10 has a positioning section 11. The positioning section 11 has a positioning hole 12. The inner wall of the positioning hole 12 has a recess 121. The surface of the recess 121 forms an engagement surface 1211. A groove 122 is formed in the lower part of the positioning hole 12. The other end of the support rod 10 has a coupling section 13.

[0025] The connecting element 20 is in a snap-fit ​​position with the positioning hole 12 of the support rod 10. The connecting element 20 has an axially extending locking orifice 21. The connecting element 20 has a circumferential portion 22 formed on an edge of one of its ends. The circumferential portion 22 is attached to the end edge of the positioning section 11. An annular flange 23 is placed on the outer wall of the connecting element 20. The annular flange 23 has a beard-shaped cross-section. The upper and lower sides of the annular flange 23 have a locking surface 231 and an inclined surface 232. The annular flange 23 is engaged with the recess 121. The locking surface 231 is engaged with the engagement surface 1211.

[0026] In this embodiment, the applicator head 30 is a nitrile-butadiene rubber (NBR) sponge, but is not limited to this material. The applicator head 30 is connected by insertion to the locking hole 21 of the connecting element 20. The lower part of the applicator head 30 has a projecting annular portion 31. The projecting annular portion 31 is inserted through the connecting element 20 and extends from one end of the connecting element 20 opposite the circumferential portion 22. The projecting annular portion 31 is partially received in the groove 122.

[0027] The diameter of the protruding annular part 31 is greater than that of the locking orifice 21, thus preventing the applicator head 30 from being detached from the connecting element 20.

[0028] The applicator head 30 may have a round, oval or teardrop shape, but not exclusively. In this embodiment, the applicator head 30 has a teardrop shape.

[0029] With reference to [Fig. 5] in conjunction with [Fig. 1], the cosmetic applicator structure 100 provided by the present invention is coupled to a lid 40 of a cosmetic container when in use. The coupling section 13 of the support rod 10 is coupled to the lid 40. In practice, the user can apply makeup by holding the lid 40 and apply the cosmetics to different parts of the face using the applicator head 30.

[0030] With the above structure, as illustrated in [Fig. 2], the support rod 10 and the applicator head 30 of the present invention are connected by means of the snap-fit ​​element 20, without the use of glue. In addition to being environmentally friendly, this can increase tensile strength and prevent the glue from being affected by incompatibility with chemical agents, which can cause the applicator head 30 to detach. Furthermore, the applicator head 30 does not need to be perforated, thus avoiding damage to the structure and extending the service life of the applicator head 30.

[0031] It is worth mentioning that the applicator head 30, being a nitrile-butadiene rubber (NBR) sponge, is very soft and highly elastic. When the applicator head 30 has cosmetic residue on it, it can be rubbed and cleaned directly. Since the applicator head 30 can quickly return to its original shape after being deformed by pressure, it is less likely to retain dirt and is convenient for repeated use.

[0032] Furthermore, as illustrated in [Fig. 3] and [Fig. 4], the annular flange 23 having a beard-shaped cross-section, when the connecting element 20 is to be locked in the positioning hole 12 of the support rod 10, the element of The link 20 can be easily inserted into the positioning hole 12 through the inclined surface 232. At this moment, the locking surface 231 is engaged with the engagement surface 1211, so that the linking element 20 is not easily disengaged from the positioning hole 12 after being locked, thus enabling rapid positioning and accurate locking.

[0033] Figure 6 illustrates another embodiment of the present invention, substantially similar to the previous preferred embodiment with the exceptions described below. The other end of the support rod 10 has another positioning section 11 instead of the coupling section 13, such that both ends of the support rod 10 are coupled to the applicator heads 30 through the connecting element 20 to increase its usability.
