Description

Technical Field

[0001] This utility model relates to the field of cosmetic tools technology, and in particular to a double-ended filler-compatible cosmetic pen. Background Technology

[0002] Makeup brushes are a common type of makeup tool, typically consisting of a penholder and a makeup component at the end of the penholder. They are used to pick up and apply liquid or cream-based cosmetics. Depending on their function, makeup brushes can be used for various makeup applications, such as eyeshadow, lipstick, and concealer. In recent years, hairline contouring sticks have become widely used as a special type of makeup brush. They primarily use a brush or sponge tip to pick up liquid or cream products for the hairline and apply them to the hairline to improve the visual effect of a sparse or uneven hairline.

[0003] However, existing hairline contouring sticks still have certain structural defects. In actual use, some makeup brushes require the cap to be open before liquid or cream can be applied, while others require the cap to be closed. They cannot simultaneously meet the requirement of applying liquid or cream both "open" and "closed," limiting their usage and making them less flexible in function. In addition, most makeup brushes on the market are currently single-ended, capable of storing only one type of liquid or cream, making it difficult to integrate multiple functions and types of cosmetics, thus limiting the application range of makeup brushes. Utility Model Content

[0004] This invention proposes a double-ended, fillable cosmetic pen to solve the problems mentioned in the background art, such as the limited functionality, restricted usage, and inability to store only a single type of cosmetic material in existing cosmetic pens.

[0007] Preferably, the pressing rod has a stepped portion on its outside, the inner wall of the pressing cover has a convex ring extending towards the center, and a first spring is sleeved on the outside of the pressing rod, with one end of the first spring abutting against the end face of the stepped portion and the other end abutting against the end face of the convex ring.

[0008] Preferably, the inner wall of the pressing outer cover is formed with an internal thread, and the outer wall of the integral structure formed by the pressing rod and the sponge clip is provided with an external thread. When the pressing rod and the sponge clip rotate simultaneously, the external thread can connect with the internal thread.

[0009] Preferably, the outer wall of the sponge clip is formed with an outwardly protruding protrusion, the end face of which can abut against the end face of the protruding ring on the inner wall of the outer cover to form an axial limit on the sponge clip.

[0010] Preferably, a triangular pen tip is installed at the end of the pen barrel, and the first cosmetic component is installed at the center of the triangular pen tip.

[0011] Preferably, the pressing rod and the sponge clip are connected or integrally formed. When it is an integrally formed structure, a retaining ring is provided in the inner cavity formed by the pressing rod and the sponge clip, and the end of the sponge clip abuts against the retaining ring.

[0012] Preferably, the second cover assembly further includes an outer cover of the ointment that is detachably connected to the end of the pen barrel. The end of the outer cover of the ointment is fixed with a tail plug. The inner shell of the ointment is slidably connected inside the outer cover of the ointment, and a second spring is installed between the inner shell of the ointment and the tail plug. The second spring applies an elastic force to the inner shell of the ointment to move in the direction of the second cosmetic component. The inner wall of the outer cover of the ointment is provided with a limiting part for axially limiting the inner shell of the ointment.

[0013] Preferably, the outer cap and the tail plug of the ointment are connected by a locking mechanism or are integrally formed.

[0022] 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.

[0023] Example 1

[0024] like Figure 1-2 As shown, a double-ended filler cosmetic pen includes a pen barrel 1, which is made of metal or plastic. To reduce its weight, the pen barrel 1 has a hollow internal structure. A first cosmetic component 8 and a second cosmetic component 13 are respectively installed at both ends of the pen barrel 1. A first cap group and a second cap group are detachably connected to both ends of the pen barrel 1. The first cap group and the second cap group cover the first cosmetic component 8 and the second cosmetic component 13, respectively. Since the two cap groups cover the two cosmetic components, they can protect the two cosmetic components and prevent dust or other debris from contaminating them. The first cover assembly includes a sponge 7 that is separated from the first cosmetic component 8 in a free state and comes into contact with the first cosmetic component 8 after being subjected to force. The sponge 7 can be used to absorb and store cosmetic liquid. The second cover assembly includes a cream inner shell 10, which has a receiving cavity 1001 for containing the cream-shaped cosmetic; the cream inner shell 10 is movable relative to the second cosmetic component 13 along the axial direction, and gradually moves closer to the second cosmetic component 13 as the cream-shaped cosmetic gradually decreases, so that the second cosmetic component 13 always remains in contact with the cream-shaped cosmetic.

[0025] Specifically, the first cover assembly also includes a press-fit outer cover 4 detachably connected to the end of the pen barrel 1. The press-fit outer cover 4 is installed at the end of the pen barrel 1 by means of a threaded connection, achieving the effect of detachable connection. A press rod 6 is slidably connected inside the press-fit outer cover 4. The sponge 7 is installed in the inner cavity of the press rod 6. A sponge clip 3 is connected to the end of the press rod 6. One end of the sponge clip 3 extends into the inside of the press rod 6 and abuts against the sponge 7. The sponge clip 3 can be used to position the sponge 7 and prevent the sponge 7 from detaching from the inside of the press rod 6. In this example, the press rod 6 and the sponge clip 3 are independent structures, and the two are fixedly connected by means of a snap-fit ​​connection. This setting can reduce the difficulty of mold opening and facilitate manufacturing.

[0026] Specifically, the pressing rod 6 has a stepped portion 601 on its outside, and the inner wall of the pressing outer cover 4 has a protruding ring 401 extending in the center direction. A first spring 5 is sleeved on the outside of the pressing rod 6. One end of the first spring 5 abuts against the end face of the stepped portion 601, and the other end abuts against the end face of the protruding ring 401. The first spring 5 can apply an axial outward elastic force to the pressing rod 6, so that there is a gap between the sponge 7 and the first cosmetic part 8 under normal conditions, and the two do not contact each other. When the pressing rod 6 is pressed for a certain stroke, the pressing rod 6, the sponge clip 3, and the sponge 7 can move simultaneously towards the first cosmetic part 8, so that the first cosmetic part 8 contacts the sponge 7.

[0027] Specifically, the outer wall of the sponge clip 3 is formed with an outwardly protruding protrusion 301. The end face of the protrusion 301 can abut against the end face of the protruding ring 401 on the inner wall of the outer cover 4 to form an axial limit on the sponge clip 3. This setting is mainly to prevent the pressing rod 6 and the sponge clip 3 from detaching from the inside of the outer cover 4.

[0028] Specifically, a triangular pen tip 2 is installed at the end of the pen barrel 1, and the first cosmetic component 8 is installed at the center of the triangular pen tip 2. In this example, the triangular pen tip 2 is connected to the pen barrel 1 by a snap-fit ​​connection. That is, the outer circumference of the triangular pen tip 2 has an outwardly protruding ring structure, while the inner wall of the pen barrel 1 is provided with an annular groove structure that matches the protruding ring structure. The protruding ring structure is placed in the annular groove structure to realize the connection between the two.

[0029] Specifically, the second cover assembly also includes a detachable outer cover 9 of the ointment body connected to the end of the pen barrel 1. A tail plug 12 is fixed to the end of the outer cover 9. In this example, the outer cover 9 and the tail plug 12 are independent components, fixed together by a snap-fit ​​connection. This arrangement facilitates product molding and reduces manufacturing difficulty. The inner shell 10 of the ointment body is slidably connected inside the outer cover 9, and a second spring 11 is installed between the inner shell 10 and the tail plug 12. The second spring 11 applies an elastic force to the inner shell 10, causing it to move towards the second cosmetic component 13. Force; The inner wall of the outer cover 9 of the ointment is provided with a limiting part 901 for axially limiting the inner shell 10 of the ointment. For example, when there is a lot of ointment inside the inner shell 10, the second cosmetic part 13 can be partially inserted into the inner shell 10 of the ointment. The inner shell 10 of the ointment is located near the tail plug 12. In this state, the second cosmetic part 13 can pick up the ointment. When there is less ointment inside the ointment, under the action of the second spring 11, the inner shell 10 of the ointment moves towards the second cosmetic part 13, so that the second cosmetic part 13 can also come into contact with the ointment to achieve the effect of dipping.

[0030] In this example, the first cosmetic component 8 is a brush, and the second cosmetic component 13 is a sponge head. It is understood that the first cosmetic component 8 and the second cosmetic component 13 could also be cosmetic components with other structural forms, such as spherical cotton balls.

[0031] Specifically, sealing rings 14 are installed at the connection between the first cap assembly and the pen barrel 1, and at the connection between the second cap assembly and the pen barrel 1, mainly for sealing purposes. In addition, sealing rings 14 are also provided at the connection between the outer cap 4 and the pressing rod 6, and at the connection between the outer cap 9 and the tail plug 12, for sealing purposes.

[0032] Example 2

[0033] like Figure 3 As shown, the only difference between this embodiment and the first embodiment above is that: in this example, the outer cover 9 and the tail plug 12 of the ointment are integrally formed; the pressing rod 6 and the sponge clip 3 are integrally formed, wherein the inner cavity formed by the pressing rod 6 and the sponge clip 3 is provided with a retaining ring 15, and the end of the sponge 7 abuts against the retaining ring 15.

[0034] Example 3

[0035] like Figure 4 As shown, the difference between this embodiment and the second embodiment described above is that: in this example, the inner wall of the pressing outer cover 4 is formed with an internal thread 402, and the outer wall of the integral structure formed by the pressing rod 6 and the sponge clip 3 is provided with an external thread 602. When the pressing rod 6 and the sponge clip 3 rotate simultaneously, the external thread 602 can connect with the internal thread 402. The main function of the threads 402 and 602 is to ensure that the pressing rod 6 can be screwed in during assembly and will not fall out. Under the action of the spring, the sponge part 7 will not come into contact with the first cosmetic part 8, but under the action of pressing, the sponge part 7 can come into contact with the first cosmetic part 8 to complete the material taking.

[0036] Example 4

[0037] like Figure 5 As shown, the difference between this embodiment and the first embodiment above is that: in this example, the pressing rod 6 and the sponge clip 3 are integrally formed structures, while the outer cover 9 of the ointment and the tail plug 12 are separate structures that are fixedly connected, specifically through a snap-fit ​​structure.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
