Description

Technical Field

[0001] This utility model relates to the field of eyeshadow pen technology, specifically a double-ended liquid eyeshadow pen. Background Technology

[0002] As a commonly used makeup product, liquid eyeshadow is increasingly favored by users due to its rich color and smooth application. Existing liquid eyeshadow pens typically feature a single-ended, single-color design, containing a certain amount of liquid eyeshadow and equipped with a brush at the tip for direct dispensing and application. While these products offer better portability than traditional eyeshadow palettes with separate brushes, they still have several shortcomings.

[0003] Most liquid eyeshadow sticks on the market currently use a simple cap-and-cover design, where the brush bristles are covered and protected by an outer cap when not in use. While this design can largely prevent the bristles from being exposed, it lacks sealing, allowing the liquid eyeshadow to gradually evaporate and dry out during storage. Furthermore, the cap-and-cover method is prone to loosening over long-term use, making it difficult to guarantee a stable protective effect.

[0004] Furthermore, most existing liquid eyeshadow sticks can only hold a single shade, and the tip shape is fixed. If users need to achieve multi-color makeup or switch between different tips, they usually need to carry multiple eyeshadow sticks, increasing the burden of carrying them when doing makeup on the go. Although some products have attempted to adopt a dual-ended design, they are mostly solid creams or simple two-color refills, and have not formed a systematic solution for liquid storage, independent expansion and contraction, and airtight protection. Therefore, they are still limited in terms of flexibility of use and preservation performance.

[0005] In summary, existing liquid eyeshadow pens generally suffer from problems such as limited functionality, insufficient sealing, and inconvenience in using multiple colors. There is an urgent need for an improved liquid eyeshadow pen that can store multiple colors of liquid in a single pen body, combine dual-ended pens, and provide controllable extension and sealing protection to meet users' needs for portability and diverse makeup effects.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a dual-ended liquid eyeshadow pen.

[0029] Combination Figures 1-5 As shown, the present invention provides a dual-ended liquid eyeshadow pen, including a pen cap 100, a screw cap 200, a plug cap 300, and two eyeshadow pen bodies 400 arranged symmetrically at the origin on the inner side of the pen cap 100.

[0030] The pen cap 100 has guide portions 110 at both ends, and the surface of the guide portion 110 has a line groove 120. The screw sleeve 200 is rotatably fitted onto the surface of the guide portion 110. The plug cap 300 is interference-fitted with the port of the screw sleeve 200 to achieve closure and protection. The eyeshadow pen body 400 includes a pen barrel 410, a pen head 420, and a liquid tube 430 fixed to one end of the pen barrel 410. The surface of the pen barrel 410 has a sliding pin 411, which is slidably fitted onto the inner side of the line groove 120, and its end passes through the line groove 120 and slides against the inner side of the guide groove 210, so that when the screw sleeve 200 rotates, it drives the eyeshadow pen body 400 to extend and retract within the pen cap 100.

[0031] Specifically, the structure, through the cooperation of the screw sleeve 200, the line groove 120, the sliding pin 411 and the rotating guide groove 210, realizes the telescopic adjustment of the pen head 420, ensuring ease of use and stability of telescopic movement.

[0032] In this embodiment, the liquid tube 430 is a semi-cylindrical tubular structure filled with eyeshadow liquid. The pen head 420 is a brush head structure, capable of directly dipping into and applying the eyeshadow liquid. The pen barrel 410 has a liquid channel inside, used to connect the liquid tube 430 and the pen head 420 to facilitate liquid export.

[0033] Specifically, when the user uses the product, the liquid is guided from the liquid tube 430 through the liquid channel to the pen head 420, and the bristles of the pen head 420 can complete the even application of eyeshadow, improving the product's functional integration; the semi-cylindrical structure of the liquid tube 430 can slide and guide each other in the axial sliding of the two eyeshadow pen bodies 400.

[0034] In this embodiment, the guide portion 110 is a straight groove structure, extending axially along the surface of the guide portion 110 to form a guide path for the sliding of the pen barrel portion 410. Positioning grooves are provided at both ends of the guide portion 110 to position the eyeshadow pen body 400 when it extends or retracts to its limit position, preventing the eyeshadow pen body 400 from freely wobbling within the pen cap 100. This design ensures the stability and accuracy of the pen head 420 in the extended and retracted positions, improving the reliability of its use.

[0035] In this embodiment, the guide groove 210 is a spiral groove arranged on the inner wall surface of the sleeve 200. When the user manually rotates the sleeve 200, the guide groove 210 interacts with the sliding pin 411, causing the eyeshadow pen body 400 to slide axially along the sliding groove 120 within the guide part 110, thereby causing the pen head 420 to extend or retract.

[0036] Specifically, this structure enables the pen head 420 to extend and retract in a controllable manner, allowing users to open and close the pen without directly touching the pen head 420, which is both convenient and hygienic.

[0037] In this embodiment, the inner cavity of the plug cover 300 is provided with a sealing ring. When the plug cover 300 is interference-fitted with the port of the screw sleeve 200, the sealing ring can fit tightly, achieving reliable sealing protection.

[0038] Specifically, this structure effectively prevents eyeshadow liquid from evaporating from the liquid tube 430, while also preventing the pen tip 420 from being contaminated by dust or impurities, thereby extending the product's lifespan and maintaining the stability of the makeup effect.

[0039] In this embodiment, both the pen cap 100 and the liquid tube 430 are made of transparent or semi-transparent materials, such as transparent polycarbonate or transparent resin. Users can visually observe the remaining amount of eyeshadow liquid through the appearance of the pen cap 100 and the liquid tube 430. This design allows users to easily monitor the usage of the eyeshadow liquid, avoiding any impact on the user experience due to insufficient liquid, and improving the product's user-friendliness.

[0040] In this embodiment, the outer surface of the pen cap 100 is provided with an anti-slip texture, such as annular grooves, granular protrusions, or a mesh structure. This structure can enhance grip friction, prevent the pen from slipping due to wet hands, and ensure stability and comfort during use.

[0041] Working principle and usage process of this utility model: Carrying and Protection Stage: When not in use, the user inserts the cap 300 into the screw cap 200 port with an interference fit. The sealing ring inside the cap 300 tightly seals the pen head 420, preventing eyeshadow liquid from evaporating from the liquid tube 430 and avoiding contamination or damage to the brush bristles. Meanwhile, the anti-slip texture on the outer surface of the pen cap 100 facilitates a stable grip, ensuring the pen's safety when carried outdoors.

[0042] Opening and Extension Stage: When the user needs to use the product, first remove the cap 300 at the corresponding end, and then rotate the sleeve 200 on that side. The spiral guide groove 210 on the inner wall of the sleeve 200 interacts with the sliding pin 411 on the surface of the pen barrel 410, causing the eyeshadow pen body 400 to slide axially along the line sliding groove 120 on the guide part 110. The pen head 420 gradually extends from the end of the pen sleeve 100 until the positioning groove limits the sliding position, and the pen head 420 is stably extended and ready for use. The two sleeves 200 can control the extension and retraction of the eyeshadow pen bodies 400 at both ends respectively; the two eyeshadow pen bodies 400 can adapt to different needs by using pen heads 420 of different shapes; the two eyeshadow pen bodies 400 can be filled with different shades of eyeshadow liquid through the liquid tube part 430 to adapt to different needs.

[0043] Application and Usage: The liquid eyeshadow in the liquid tube 430 is automatically drawn into the bristles of the brush head 420 by the liquid channel. The user directly dips the brush head 420 into the liquid and applies it evenly to the eyelids to complete the eyeshadow application or blending. Since the two eyeshadow brush bodies 400 are symmetrically arranged at the origin, the user can select different ends of the brush head 420 as needed to switch between different colors or makeup effects.

[0044] Retraction and Sealing Stage: After use, the user rotates the sleeve 200 again, and the sliding pin 411 slides in the opposite direction along the spiral guide groove 210, causing the pen head 420 to gradually retract into the pen sleeve 100. Then, the cap 300 is put on, and the sealing ring is used to achieve a closed seal, ensuring that the eyeshadow liquid does not easily evaporate and preventing contamination.

[0045] Remaining amount observation: During daily use, both the pen cap 100 and the liquid tube 430 are made of transparent or semi-transparent materials, allowing users to visually observe the remaining amount of eyeshadow liquid.
