Description

Technical Field

[0001] This utility model relates to the field of cosmetics, and in particular to a cosmetic pen. Background Technology

[0002] Existing makeup brushes use freeze-dried or baked powder refills, which are fixed to the outside of a wooden handle to form the brush. However, when the refill is placed inside the handle, the low structural strength of the refill makes it prone to breakage during processing or use, affecting the sales and use of subsequent products.

[0005] As a further description of the above technical solution: the membrane is disposed on the side wall and bottom of the pen barrel.

[0006] As a further description of the above technical solution: one end face of the cavity of the pen barrel is connected to the outside, which is used to house the pen refill.

[0007] As a further description of the above technical solution: the pen refill is coplanar with one end face of the pen barrel.

[0008] As a further description of the above technical solution: the pen core extends to the outside of one end of the pen barrel and forms a conical surface with the pen barrel.

[0009] As a further description of the above technical solution: the end of the pen barrel away from the conical surface is an arc surface.

[0010] As a further description of the above technical solution: the diameter of the pen barrel is 11-12mm.

[0011] As a further description of the above technical solution: the diameter of the pen refill is 5.42-6.85mm.

[0012] As a further description of the above technical solution: the thickness of the membrane is 0.08-0.15 mm.

[0013] As a further description of the above technical solution: the outer diameter of the membrane body disposed within the cavity of the pen barrel is 5.5-7.0 mm.

[0014] The above technical solution has the following advantages or beneficial effects: By placing a film between the pen barrel and the pen refill, the film covers the pen refill located inside the pen barrel, enhancing the connection strength between the pen refill and the pen barrel, reducing the product defect rate during processing, and at the same time, the thickness of the film makes it easier to cut during use.

[0016] Legend: 1. Pen barrel; 2. Membrane body; 3. Pen refill. Detailed Implementation

[0017] 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.

[0018] Reference Figure 1 One embodiment of this utility model is a cosmetic pen, comprising: a pen barrel 1, the pen barrel 1 having a cavity; a membrane 2 being disposed on the inner side of the cavity; and a pen core 3 being disposed on the inner side of the cavity, the pen core 3 being connected to the pen barrel 1 through the membrane 2.

[0019] In this embodiment, a cavity is provided inside the pen barrel 1 to provide installation space for the pen refill 3. A membrane 2 is provided in the cavity of the pen barrel 1 to connect the pen barrel 1 and the pen refill 3. The membrane 2 is a plastic film, which can be made of PE, PP, PET and PETG. The membrane 2 and the pen barrel 1 are bonded with white glue to fix the pen refill 3, enhance the connection strength between the pen refill 3 and the pen barrel 1, and reduce the product defect rate during the processing.

[0020] The membrane 2 is disposed on the side wall and bottom of the pen barrel 1.

[0021] In this embodiment, the membrane 2 is disposed on the side wall and bottom of the pen barrel 1 cavity to cover and support the pen core 3 in the circumference and one end, thereby increasing the structural strength of the pen core 3 within the pen barrel 1 and reducing the probability of breakage.

[0022] One end face of the cavity of the pen barrel 1 is connected to the outside world to house the pen refill 3.

[0023] In this embodiment, by making an opening in the cavity of the pen barrel 1, a channel is reserved for the assembly and use of the pen refill 3, so that the pen refill 3 can be easily placed inside the pen barrel 1. The pen refill 3 is a freeze-dried pen refill or a baked powder pen refill. Furthermore, the pen refill 3 at the opening is protected by the pen cap (existing technology, not shown in the figure) snapping into the pen barrel 1.

[0024] Reference Figure 2 The pen refill 3 and one side end face of the pen barrel 1 are coplanar.

[0025] In this embodiment, when not in use, the pen refill 3 is coplanar with one side end face of the pen barrel 1, and the pen refill 3 is located inside the pen barrel 1, making it more convenient to place the pen refill 3 inside the pen barrel 1 during processing.

[0026] Continue to refer to Figure 1 The pen core 3 extends to the outer side of one end of the pen barrel 1 and forms a conical surface with the pen barrel 1.

[0027] In this embodiment, during use, the pen barrel 1 and the pen core 3 are cut to form a conical structure, which can guide the user to accurately control the pen tip's landing point and facilitate user use.

[0028] The end of the pen barrel 1 that is away from the conical surface is an arc surface.

[0029] In this embodiment, by setting one end of the pen barrel 1 as an arc surface, the harshness of the right-angled edge is avoided, and the pressure of holding it can be distributed through the arc surface during the makeup process.

[0030] The diameter of pen barrel 1 is 11-12mm.

[0031] In this embodiment, the diameter of the pen barrel 1 is based on ergonomic design to avoid being too thin and causing unstable grip, and to avoid being too thick and causing fatigue during use. Optionally, the diameter of the pen barrel 1 is 11.6mm.

[0032] The diameter of pen refill 3 is 5.42-6.85mm.

[0033] In this embodiment, the diameter of the pen core 3 is smaller than the diameter of the pen barrel 1, and a gap is formed between the pen core 3 and the pen barrel 1 to accommodate the membrane 2. Optionally, the diameter of the pen core 3 is 6.3 mm.

[0034] The thickness of membrane 2 is 0.08-0.15 mm.

[0035] In this embodiment, by designing the thickness of the membrane 2, it not only supports the pen refill 3, but also facilitates cutting during use. Optionally, the thickness of the membrane 2 is 0.1mm to avoid excessive thickness that would cause the connection between the pen refill 3 and the pen barrel 1 to be too rigid, resulting in inconvenient cutting.

[0036] The membrane 2 is set inside the cavity of the pen barrel 1 with an outer diameter of 5.5-7.0 mm.

[0037] In this embodiment, the membrane 2 covers the outside of the pen refill 3, so that the outer diameter of the membrane 2 matches the inner diameter of the pen barrel 1 cavity. The outer diameter of the membrane 2 can be 6.5 mm.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
