Description

Technical Field

[0001] This application relates to cosmetic tools, specifically a combination applicator. Background Technology

[0002] Cosmetics have become necessities in people's lives. For ease of carrying, cosmetic materials are generally stored in cosmetic containers, with spreadable containers being a common type. Spreadable containers typically consist of a bottle and an applicator, which usually includes an applicator head and a brush handle. Currently, the assembly method of the applicator head and brush handle is irreversible; once assembled, they cannot be disassembled. Furthermore, the applicator head is extremely prone to wear and tear. Therefore, when the applicator head is no longer usable, the entire applicator must be discarded, increasing the user's cosmetic costs and wasting resources. Summary of the Invention

[0003] To overcome the above-mentioned defects, this application provides a combined applicator in which the applicator head and the connecting rod are detachably connected. When the applicator head is damaged, only the applicator head needs to be replaced, which reduces the user's makeup costs and reduces the waste of resources.

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

[0005] A combined applicator includes an applicator head, a connecting rod, and a brush rod. A first end of the connecting rod is detachably connected to the applicator head, and a second end of the connecting rod is connected to the brush rod. The connecting rod is disposed between the applicator head and the brush rod.

[0006] Optionally, the applicator head includes an applicator portion and an mounting portion that are fixedly connected, and the connecting rod includes an insert portion and a engage portion that are fixedly connected. The engage portion is detachably connected to the mounting portion, and the insert portion is connected to the brush rod.

[0007] Optionally, the connection between the engaging part and the mounting part can be a threaded connection, a magnetic adsorption connection, or a snap-fit ​​connection.

[0008] Optionally, the engaging portion is provided with an installation groove, a slot and an elastic element, the elastic element is provided with a claw, the mounting portion is inserted into the installation groove, and the claw engages in the slot to fix the mounting portion in the engaging portion.

[0009] Optionally, the first end of the elastic element is fixedly connected to the engaging part, the second end of the elastic element is a free end, the inner side of the elastic element is provided with two claws, the mounting groove and the slot are interconnected, and when the claws engage with the slot, there is a notch between the engaging part and the elastic element.

[0010] Optionally, both the inner wall of the engaging portion and the inner wall of the elastic element 3 are provided with protrusions, and the outer wall of the mounting portion is provided with a groove that mates with the protrusions; or both the inner wall of the engaging portion and the inner wall of the elastic element are provided with grooves, and the outer wall of the mounting portion is provided with protrusions that mate with the grooves.

[0011] Optionally, the engaging portion and the mounting portion are detachably connected together via snaps and slots.

[0012] Optionally, the brush rod is fixedly connected to the plug-in portion, or the brush rod is detachably connected to the plug-in portion.

[0013] Optionally, the brush rod has a socket and a locking point protruding towards the socket. The plug is inserted into the socket and has a sliding groove.

Detailed Implementation

[0026] 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 described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of 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.

[0027] 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, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a 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.

[0028] 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.

[0029] like Figure 1-9 As shown, a combined applicator includes an applicator head 10, a connecting rod 20, and a brush rod 50. The first end of the connecting rod 20 is detachably connected to the applicator head 10, and the second end of the connecting rod 20 is connected to the brush rod 50. The connecting rod 20 is positioned between the applicator head 10 and the brush rod 50. This combined applicator is installed in a cosmetic bottle used to store cosmetic materials, such as adhesive cosmetics, lip gloss, mascara, eyelash powder, hair color, etc. The first end of the brush rod 50 is fixedly connected to a cap 52. In one embodiment, the cap 52 is detachably screwed onto the mouth of the cosmetic bottle; alternatively, the cap 52 can be attached to the cosmetic bottle via a snap-fit ​​or other detachable method. The second end of the brush rod 50 is connected to the connecting rod 20. The brush rod 50 and the connecting rod 20 can be fixedly connected or detachably connected. The applicator head 10 is used to pick up cosmetic materials from the cosmetic bottle and apply them to the face. In this applicator, the applicator head 10 is detachably connected to the connecting rod 20. In this application, the applicator head 10 is mounted on the brush handle 50 via the connecting rod 20. The applicator head and the connecting rod are assembled in a detachable manner. Therefore, when the applicator head is damaged or needs to be replaced, only the old applicator head needs to be removed and replaced with the new one, without having to replace the entire applicator. This reduces the user's makeup costs and also reduces resource waste. The detachable connection between the applicator head and the connecting rod also facilitates the sorting and disposal of the product when it is discarded. This allows applicators and connecting rods made of different types of materials or the same type of materials but different specifications to be separated and recycled separately, which is beneficial for resource recycling and reuse.

[0030] like Figure 1-5As shown, the applicator head 10 includes an applicator portion 11 and a mounting portion 12 fixedly connected. The connecting rod 20 includes a plug-in portion 30 and a locking portion 40 fixedly connected. The locking portion 40 is detachably connected to the mounting portion 12, and the plug-in portion 30 is connected to the brush rod 50. The second end of the brush rod 50 is connected to the plug-in portion 30 of the connecting rod 20. The applicator head 10 is divided into an applicator portion 11 and a mounting portion 12. The applicator portion 11 is used to pick up cosmetic materials from the cosmetic bottle and use them for makeup application, and the mounting portion 12 is used to connect to the locking portion 40.

[0031] It should be noted that the connector 30 is connected to the brush handle 50 via a dotted connection. The specific operation of this dotted connection is described below. First, the connector 30 is inserted into the cavity of the brush handle 50; then, a dotted tool is used to press the outer wall of the brush handle 50, so that the inner wall of the brush handle 50 and the outer wall of the connector 30 form a compressed portion, thereby making the connection between the applicator head 10 and the brush handle 50 more secure.

[0032] The engaging part 40 and the mounting part 12 can be assembled in various detachable ways. Optionally, the connection between the engaging part 40 and the mounting part 12 can be a threaded connection, a magnetic plate adsorption connection, or a snap-fit ​​connection. Specifically, the threaded connection means that the engaging part 40 and the mounting part 12 are respectively provided with mutually mating internal threads and external threads. During assembly, the two are detachably screwed together by the internal and external threads. Specifically, the magnetic plate adsorption connection means that mutually attractive magnetic plates are respectively installed in the engaging part 40 and the mounting part 12. During assembly, the two are directly attracted together by the magnetic plates.

[0033] For the soft material and small size of the applicator head 10 and connecting rod 20, a snap-fit ​​connection is a better choice. The snap-fit ​​connection between the snap-fit ​​part 40 and the mounting part 12 includes the following two specific implementation schemes (Example 1 and Example 2):

[0034] Example 1: As Figure 1-5 As shown, the engaging portion 40 is provided with a mounting groove 41, a slot 42, and an elastic element 43. The elastic element 43 is provided with a claw 44. The mounting portion 12 is inserted into the mounting groove 41, and the claw 44 engages in the slot 42, thereby fixing the mounting portion 12 in the engaging portion 40. Figure 4As shown, the mounting part 12 has an elongated oval cross-section. The mounting groove 41 on the engaging part 40 has the same structure as the mounting part 12. When the mounting part 12 is tightly fitted into the mounting groove 41, the applicator head 10 cannot rotate relative to the connecting rod 20, thus improving the stability of the applicator head 10 during makeup application. Of course, the cross-section of the mounting part 12 can also be polygonal, elliptical, or other non-circular irregular shapes, i.e., the mounting part 12 can be a non-cylindrical structure. At the same time, the elastic element 43 is attached to the engaging part 40 and the claw 44 is engaged in the groove 42. The claw 44 clamps the mounting part, preventing the applicator head 10 from being pulled out of the connecting rod 20, thus fixing the two together. When the applicator head 10 needs to be replaced, simply open the elastic element 43 to disengage the claw 44 from the groove 42, and then pull out the applicator head 10. Therefore, the operation is very convenient.

[0035] like Figure 5 As shown, the first end of the elastic member 43 is fixedly connected to the engaging part 40, the second end of the elastic member 43 is a free end, and the inner side of the elastic member 43 is provided with two claws 44. The mounting groove 41 and the slot 42 are connected to each other. When the claws 44 are engaged in the slot 42, there is a notch 45 between the engaging part 40 and the elastic member 43. Except for its first end, which is fixedly connected to the engaging part 40, the elastic element 43 is not connected to the engaging part 40 at any other part. That is, the elastic element 43 can rotate relative to the engaging part 40 around its first end. During assembly, after the mounting part 12 is inserted into the mounting groove 41, the elastic element 43 is closed onto the engaging part 40. The two claws 44 engage precisely in the slots 42 on both sides of the mounting part 12. After the elastic element 43 is fitted against the engaging part 40, it forms a cylindrical structure. The mounting groove formed after the two parts are joined is equal to or slightly larger than the mounting part 12. Therefore, the mounting part 12 can fit tightly into the mounting groove 41 and be clamped and fixed by the claws 44 on both sides, so that the applicator head is firmly installed in the connecting rod. Figure 2 As shown, when the elastic element is engaged with the engaging part, a notch 45 is provided between the engaging part 40 and the elastic element 43, so that the elastic element 43 can be pried away from the engaging part 40 and the applicator head 10 can be removed when disassembling.

[0036] In one implementation, such as Figure 5As shown, both the inner wall of the engaging portion 40 and the inner wall of the elastic member 43 are provided with protrusions 46, and the outer wall of the mounting portion 12 is provided with grooves 13 that mate with the protrusions 46. In another embodiment, both the inner wall of the engaging portion 40 and the inner wall of the elastic member 43 are provided with grooves 13, and the outer wall of the mounting portion 12 is provided with protrusions 46 that mate with the grooves 13. During assembly, the protrusions 46 fit perfectly into the grooves 13. That is, the axial movement between the engaging portion 40 and the mounting portion 12 is further limited by the protrusions 46 and the grooves 13, which improves the firmness of the connection between the two. Therefore, the engaging portion and the mounting portion are limited in the axial direction by the protrusions and grooves, and in the circumferential direction by the non-cylindrical structure of the engaging portion. They are clamped and fixed by the elastic member and the engaging portion, so that the application head and the connecting rod are firmly connected, ensuring that the application head will not shake during the makeup process.

[0037] Example 2: Not shown in the figure, the engaging part 40 and the mounting part 12 are detachably connected together by a snap fastener and a slot. Optionally, the engaging part 40 is a hollow cylindrical structure, with the hollow part serving as a mounting groove. In one embodiment, the engaging part 40 has a snap fastener extending towards the mounting groove, and the outer wall of the mounting part 12 has a slot that mates with the snap fastener. In another embodiment, the engaging part 40 has a slot that communicates with the mounting groove, and the outer wall of the mounting part 12 has a snap fastener that mates with the slot.

[0038] In one embodiment, the brush rod 50 is fixedly connected to the plug-in portion 30. Optionally, the brush rod 50 and the plug-in portion 30 are fixedly engaged by dotting (i.e., after the two are assembled, dots are made directly but not through, so that the two are fixed together), press-fit, or adhesive. (In another embodiment, the brush rod 50 is detachably connected to the plug-in portion 30.)

[0039] Optionally, the brush rod 50 can be connected to the insertion part 30 by a threaded connection, a magnetic adsorption connection, or a snap-fit ​​connection. The threaded connection and magnetic adsorption connection are similar to the connection between the snap-fit ​​part 40 and the mounting part 12 described above, and will not be repeated here.

[0040] The brush rod 50 and the plug-in part 30 can be connected by various snap-fit ​​methods. Optionally, in embodiment 3: Figure 6-9 As shown, the brush rod 50 has a socket 53 and a locking point 51 protruding towards the socket 53. The insertion part 30 is inserted into the socket 53. The insertion part 30 has a sliding groove 31. The sliding groove 31 includes a first sliding track and a second sliding track that are interconnected. During assembly, the locking point 51 can be locked into the sliding groove 31 to fix the insertion part 30 to the brush rod 50.

[0041] like Figure 8As shown, the brush rod 50 is a hollow cylindrical structure, with the hollow part being the insertion hole 53. Near the second end of the brush rod 50, there are two locking points 51 protruding towards the insertion hole 53. Correspondingly, as... Figure 9 As shown, the end of the insertion part 30 away from the engaging part 40 is provided with two sliding grooves 31. The first sliding track is arranged along the axial direction of the insertion part 30, and the upper end of the first sliding track is open. The second sliding track is arranged along the circumferential direction of the insertion part 30, and the left end of the second sliding track is connected to the lower end of the first sliding track, and the right end of the second sliding track is closed. Optionally, the first sliding track and the second sliding track are arranged perpendicular to each other. During assembly, the insertion part 30 is inserted into the insertion hole of the brush rod 50. First, the locking point 51 slides along the first sliding track. When the locking point slides to the lower end of the first sliding track, the connecting rod 20 is rotated counterclockwise, so that the locking point 51 slides into the closed end of the second sliding track, thus completing the assembly process. Through the mutual cooperation of the locking point 51 and the sliding groove 31, the connecting rod 20 is firmly installed in the brush rod 50, and the installation and disassembly of both are very convenient. When it is necessary to replace the entire applicator head and the connecting rod, it is only necessary to rotate the connecting rod in the opposite direction and pull the connecting rod off the brush rod.

[0042] Both the applicator head 10 and the connecting rod 20 can be manufactured by injection molding. The materials of the applicator head 10 and the connecting rod 20 can be selected from one of the following materials: thermoplastic materials, elastomer materials, thermoplastic elastomers, and thermoplastic polyester elastomers, such as: nitrile rubber, silicone rubber, ethylene propylene diene monomer (EPDM) rubber, styrene-ethylene-butene-styrene (SEBS), polyurethane (PU), ethyl acetate (EVA), polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), thermoplastic elastomer (TPE), thermoplastic polyester elastomer (TPEE), etc., but are not limited to these. Optionally, both the applicator head 10 and the connecting rod 20 can be made of thermoplastic elastomer or thermoplastic polyester elastomer materials, and the hardness of the applicator head 10 is less than the hardness of the connecting rod 20. Optionally, both the applicator head 10 and the connecting rod 20 are made of thermoplastic elastomer (TPE) material, and the hardness of the thermoplastic elastomer used to make the applicator head is less than the hardness of the thermoplastic elastomer used to make the connecting rod 20. The applicator head 10 is made of low-hardness TPE, which is convenient for makeup application, while the connecting rod 20 is made of harder TPE, which is convenient for fixing the applicator head 10 and the brush rod 50.

[0043] 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.
