Description

Technical Field

[0001] This application relates to cosmetic tools, specifically to an embedded applicator. Background Technology

[0002] To improve the coating effect, in addition to the traditional plastic parts, the coating head also has a metal part. The two are fixed together by the rods on the metal part and the rods on the plastic part. However, during long-term use, the plastic part and the metal part are prone to loosening or even separation, causing great inconvenience to users. Utility Model Content

[0003] To overcome the above-mentioned defects, this application provides an embedded applicator in which the insert is directly installed on the applicator and the insert and the applicator head are directly engaged and fixed by the joint and the slot, so the two are easy to assemble and have high bonding strength.

[0004] The technical solution adopted by this application to solve its technical problem is:

[0005] An embedded applicator includes an applicator head and an insert mounted on the applicator head. The hardness of the applicator head is less than that of the insert. The applicator head includes an integrally injection-molded applicator and a rod. The rod is fixedly connected to the proximal end of the applicator. A ring-shaped groove is formed on the surface of the applicator. A ring-shaped engagement portion is formed on the outer edge of the insert. The engagement portion is embedded in the groove to engage and fix the insert to the applicator.

[0006] Optionally, the coating material deforms during the process of the joint being inserted into the slot.

[0007] Optionally, the insert includes a coating surface, which includes at least one of a convex surface, a planar surface, and a concave surface.

[0008] Optionally, the edge of the coating surface is connected to the joint, a step is formed between the coating surface and the joint, and the step abuts against the slot.

[0009] Optionally, the applicator has a deformable portion along the slot. When the connecting portion is inserted into the slot, the deformable portion deforms to make the connecting portion snap into place.

[0010] Optionally, in any direction passing through the center of the joint (220), the outer diameter of the joint is larger than the inner diameter of the groove of the deformable part.

[0011] Optionally, after assembly, the deformable part is interference-fitted with the step.

[0012] Optionally, a support block is fixedly provided inside the coating component, and the slot is formed between the support block and the deformable part. A receiving cavity is formed inside the insert, the insert covers the support block, and the support block is placed inside the receiving cavity.

[0013] Optionally, a flocked layer is formed on the outer surface of the applicator; or, the outer surface of the applicator is provided with flocking that is integrally formed with the applicator head.

[0014] The beneficial effects of this application are as follows: In this application, the insert is directly installed on the applicator, and the insert and the applicator head are directly engaged and fixed through the joint and the slot. Therefore, the two are easy to assemble and have high bonding strength, effectively preventing them from falling off. The insert has a ring of joints around its perimeter, which is used to assemble it into the slot, increasing the bonding area between the insert and the applicator head and further stabilizing their bonding strength. Since the applicator and the insert have different hardnesses, different application areas can achieve different makeup effects during use, thus meeting different user needs and broadening the application range of the applicator.

Detailed Implementation

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such uses of the terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0036] Example: Figure 1-17 As shown, an embedded applicator includes an applicator head 100 and an insert 200 mounted on the applicator head 100. The hardness of the applicator head 100 is less than that of the insert 200. The applicator head 100 includes an integrally injection-molded applicator part 110 and a rod 120. The rod 120 is fixedly connected to the proximal end of the applicator part 110. A ring-shaped groove 111 is formed on the surface of the applicator part 110. The outer edge of the insert 200 forms a ring-shaped engagement portion 220, which is embedded in the groove 111 to engage and fix the insert 200 with the applicator part 110. Optionally, the material of the insert 200 includes a temperature-sensitive material, such as metal, ceramic, glass, or stone. The applicator part 110 includes a proximal end and a distal end arranged opposite to each other. The end of the applicator part 110 that engages with the rod 120 is defined as the proximal end, and the end of the applicator part 110 away from the rod 120 is the distal end. The distal end of the applicator part 110 is a free end.

[0037] In this application, the connecting portion 220 of the insert 200 presses against the groove 111 of the applicator head 100, causing the groove wall of the groove 111 to undergo elastic deformation. Subsequently, the connecting portion 220 is inserted into the groove 111. After the groove wall of the groove 111 returns to its original shape, the groove wall and the connecting portion 220 of the insert 200 are pressed against each other, so that the insert 200 and the groove 111 are engaged and fixed. The insert 200 is provided with a ring of connecting portions 220 around its perimeter. By using the ring of connecting portions 220 to assemble in the groove 111, the bonding area between the insert 200 and the applicator head 100 is increased, further stabilizing the bonding strength between the two.

[0038] In some other embodiments, after the connecting part 220 is engaged in the slot 111, the groove wall of the slot 111 maintains a certain amount of deformation and abuts against the connecting part 220, so that the insert 200 is engaged and fixed with the slot 111.

[0039] The outer surface of the applicator 110 and the outer surface of the insert 200 together form the application area. Since the applicator 110 and the insert 200 have different hardnesses, different application areas can achieve different makeup effects during use, which can meet the different needs of users and broaden the application range of the applicator.

[0040] like Figure 17 As shown, during the process of the joint 220 being inserted into the slot 111, the applicator 110 deforms. The joint 220 has a ring-shaped structure, that is, under the pressure of the joint 220, the applicator 110 deforms outward before the joint 220 can be squeezed into the slot 111. After assembly, the applicator 110 returns to its original shape to clamp the joint 220, so that the insert 200 is firmly fixed in the applicator 110.

[0041] Optionally, the insert 200 includes a coating surface 210, which includes at least one of a convex surface, a flat surface, and a concave surface. The coating surface 210 can be a smooth surface or a rough surface, and this disclosure does not limit this. In this embodiment, as... Figure 12-16 As shown, the application surface 210 is convex, and the insert 200 is made of stainless steel. Users can use the application surface 210 to apply a cooling compress or massage to the skin to accelerate the absorption of cosmetics and provide a cooling sensation. The metallic shape enhances the applicator's premium appearance, and users can experience multiple application sensations, facilitating precise makeup steps and achieving excellent results. In other embodiments, the application surface 210 is smooth, allowing for the creation of logos, text, patterns, etc., which are highly visible and reduce the amount of excess material carried by the applicator head each time, minimizing waste.

[0042] like Figure 14 As shown, the edge of the coating surface 210 connects to the joint 220, and a step 221 is formed between the coating surface 210 and the joint 220. That is, the coating surface 210 and the joint 220 are not flush, and the step 221 abuts against the slot 111. In this embodiment, the structure of the insert 200 includes a sheet-like structure, and the insert 200 is generally elliptical. Of course, it can also be designed as a circle, square, or other irregular shape. By designing the insert 200 as a sheet, the size of the insert 200 can be minimized while meeting different coating requirements, thereby reducing the overall weight of the applicator and lowering the manufacturing cost of the applicator. Moreover, the sheet-like insert 200 only connects to the coating part 110, making assembly convenient.

[0043] like Figure 7-11 and Figure 17As shown, the applicator 110 has a deformable portion 113 along the slot 111. When the connecting portion 220 is inserted into the slot 111, the deformable portion 113 deforms to engage the connecting portion 220. After assembly, the deformable portion 113 returns to its original shape and is secured to the connecting portion 220. Optionally, the surface of the applicator 110 includes a first flocked surface 115 and a second flocked surface 116 arranged opposite to each other. Optionally, the first flocked surface 115 has a convex structure, and the second flocked surface 116 has a planar, concave, or convex structure. A slot 111 is formed on the first flocked surface 115, and the connecting portion 220 on the insert 200 is engaged in the slot 111. Therefore, the bonding area between the insert 200 and the applicator 110 is large, and the bonding strength is high.

[0044] Optionally, in any direction passing through the center of the joint 220, the outer diameter of the joint 220 is larger than the inner diameter of the groove of the deformable part 113. The outer diameter of the joint 220 refers to the size of the outer edge of the joint 220 in its natural state, and the inner diameter of the groove of the deformable part 113 refers to the size of the inner edge of the groove. The shape of the outer edge of the joint 220 is the same as the shape of the groove formed by the deformable part 113. The shapes of the outer edge of the joint 220 and the groove formed by the deformable part 113 can be elliptical, circular, square, etc. When both are circular structures, the outer diameter of the joint 220 refers to the diameter of the circle; when both are elliptical structures, the outer diameter can be the length of the major and minor axes of the ellipse; when both are square structures, the outer diameter can be the length of each side of the square structure.

[0045] like Figure 1 and Figure 15 As shown, after assembly, the deformable part 113 is clamped onto the step 221, with an interference fit between the deformable part 113 and the step 221. The area around the applicator 110 near the slot 111 is defined as the deformable part 113. The insert 200 extends outwards to form a connecting part 220. The size of the connecting part 220 is larger than the size of the slot formed by the deformable part 113. When the connecting part 220 needs to enter the slot 111 through the slot, the deformable part 113 needs to undergo elastic deformation to enlarge the slot, facilitating the passage of the connecting part 220. After the connecting part 220 is engaged in the slot 111, the deformable part 113 completely returns to its original shape to clamp onto the step 221, thereby improving the bonding strength between the insert 200 and the applicator 110. In other embodiments, the deformable part 113 partially returns to its original shape to clamp onto the step 221, meaning that the assembled deformable part 113 undergoes slight deformation compared to its original state.

[0046] like Figure 7-11 As shown, a support block 112 is fixedly provided inside the coating part 110, and a groove 111 is formed between the support block 112 and the deformable part 113, such as Figure 1 and Figure 14As shown, an accommodating cavity 230 is formed inside the insert 200, the insert 200 covers the support block 112, and the support block 112 is placed inside the accommodating cavity 230. The support block 112 is located at the center of the coating member 110. During flocking, a flocked layer 114 is formed on the outer surface of the coating member 110, but no flocked layer 114 is formed on the outer surface of the support block 112, that is, the support block 112 is smooth. When the insert 200 is installed on the coating member 110, the support block 112 is covered by the insert 200, and the support block 112 provides support force to the insert 200 to prevent the insert 200 from denting.

[0047] In one possible implementation, such as Figure 1-4 As shown, a flocked layer 114 is formed on the outer surface of the applicator 110; in another possible embodiment, not shown in the figure, the outer surface of the applicator 110 is provided with plastic fluff integrally formed with the applicator head 100. The flocked layer 114 and the plastic fluff are used to facilitate the carrying of cosmetic or skin care materials. The flocked layer 114 is formed by a flocking process; the plastic fluff and the applicator head 100 are integrally formed by an injection molding process.

[0048] When the outer surface of the coating part 110 is a flocked layer 114 coating part, the manufacturing method is as follows:

[0049] Step 1: Molding: The applicator head 100 and the insert 200 are molded separately; optionally, the applicator head 100 is made of plastic by injection molding, and the insert 200 is made of metal by cold rolling or hot rolling.

[0050] Step 2: Flocking: A flocking layer 114 is formed on the outer surface of the coated part 110 through a flocking process; no flocking layer 114 is formed on the outer surface of the support block 112.

[0051] Step 3 Assembly: Insert the connecting part 220 into the slot 111 to engage and fix the insert 200 and the coating part 110. During the process of inserting the connecting part 220 into the slot 111, the coating part 110 deforms.

[0052] When the joint 220 needs to enter the slot 111 through the groove of the deformable part 113, the deformable part 113 on the coating part 110 deforms to enlarge the groove so that the joint 220 can be inserted; after the joint 220 is inserted into the slot 111, the deformable part 113 returns to its original shape to clamp onto the step 221, thereby improving the bonding strength between the insert 200 and the coating part 110.

[0053] Figure 17 A schematic diagram of the applicator assembly process is shown. Figure 17 The topmost image shows the state of the applicator head 100 and the insert 200 before assembly, that is, the applicator head 100 and the insert 200 are in a separated state; Figure 17The middle diagram shows the state of the applicator head 100 and the insert 200 during the assembly process. The insert 200 is subjected to force and is inserted into the applicator 110 along the assembly direction arrow in the diagram. The deformable part 113 is deformed in the direction of deformation arrow in the diagram under the compression of the joint 220. Figure 17 The bottommost diagram shows the state after the applicator head 100 and the insert 200 are assembled. The joint 220 is embedded in the slot 111, the insert 200 covers the support block 112, and the support block 112 is placed in the receiving cavity 230.

[0054] When the outer surface of the coating part 110 is plastic velvet, its manufacturing method is as follows:

[0055] Step 1: Molding: The applicator head 100 and insert 200 are molded separately, with the outer surface of the applicator head 100 forming an integrally molded plastic fluff. Specifically, during the molding process of the applicator head 100, plastic particles are injected into a mold. The mold has micro-grooves for forming the plastic fluff. After injection molding, the outer surface of the applicator 110 forms an integral plastic fluff with the applicator head 100, wherein the diameter of the plastic fluff is less than or equal to 0.2 mm. In one possible implementation, the plastic fluff, when performing the function of applying skincare or makeup products, has the same effect as the fiber fluff traditionally flocked to the surface of the applicator 110. In one possible naming scheme, the applicator 110 can also be called a flock-free cotton pad head.

[0056] Step 2: Assembly: Insert the connecting part 220 into the slot 111 to engage and fix the insert 200 and the coating part 110. During the process of inserting the connecting part 220 into the slot 111, the coating part 110 deforms.

[0057] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
