Description

Technical Field

[0001] This utility model relates to the field of fluorescent pen technology, specifically a fluorescent pen with refillable pigment. Background Technology

[0002] Highlighters have a writing tip. During use, the ink is absorbed into the tip and can be displayed on paper by manual operation. Key areas can be marked by covering them with fluorescent ink containing fluorescent agents. The transparent material used to make the pen casing can enhance the aesthetics of the highlighter.

[0003] Chinese utility model patent CN221023017U discloses a highlighter pen, including a cap and a barrel. A transparent cap sleeve is detachably fixed to the cap, and a transparent barrel sleeve is detachably fixed to the barrel. By adding a transparent cap sleeve and barrel sleeve to the traditional highlighter pen cap and barrel, this new highlighter pen has a more aesthetically pleasing appearance and an added snap-fit ​​structure, enhancing sealing and extending its lifespan.

[0004] Based on existing solutions and actual production and processing, it is inconvenient to refill the transparent inner tube of existing highlighters when the ink inside runs out. Usually, the cap is connected to the transparent outer shell by plugging and unplugging. Excessive force during plugging and unplugging can easily cause ink to splatter on the highlighter tip. Therefore, we propose a highlighter that can be refilled with ink to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a refillable highlighter to solve the problem mentioned in the background art: when the pigment inside the transparent inner tube of the existing highlighter is used up, it is inconvenient to refill the pigment inside the transparent inner tube. Usually, the pen cap is connected to the transparent outer shell by plugging and unplugging. Excessive force during plugging and unplugging can easily cause the pigment on the highlighter tip to splatter.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fluorescent pen with refillable pigment, comprising a transparent outer shell, a transparent inner tube, and a fluorescent pen tip:

[0007] The transparent outer shell contains a transparent pen inner tube, and a receiving ring is fixed to the inner wall of the top of the transparent pen inner tube. A blocking block is attached above the receiving ring. A top cover is threaded to the top of the transparent outer shell. A fluorescent pen tip is installed at the bottom of the inner tube. A pen cap is movably installed at the bottom of the transparent outer shell.

[0008] An elastic rubber ring is provided on the outer side of the transparent shell, and a conical pad is provided on the inner side of the elastic rubber ring.

[0009] The above technical solution facilitates the filling of ink into the transparent pen tube for reuse, and allows for slight removal of the pen cap to prevent ink splattering.

[0010] Preferably, the bottom end of the transparent pen inner tube has a concave-convex structure, so that the transparent pen inner tube defines the interior of the transparent outer shell.

[0011] Preferably, the upper surface of the plug is in contact with the lower surface of the top cover, and the plug is connected to the transparent pen inner tube by a snap-fit ​​connection, which facilitates the disassembly and assembly of the plug and the transparent pen inner tube and makes it easy to expose the opening at the top of the transparent pen inner tube.

[0012] Preferably, the pen cap and the transparent outer shell are connected by a threaded connection, which facilitates the disassembly and assembly of the pen cap and the transparent outer shell.

[0013] Preferably, the conical pad is fixed to the outside of the transparent shell by an elastic rubber ring, which facilitates confining the conical pad to the transparent shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the refillable fluorescent pen makes it convenient to add pigment into the transparent inner tube for repeated use, and the pen cap can be slightly removed to avoid pigment splattering;

[0015] 1. The top of the transparent outer shell is threaded with a top cap. The plug is inserted into the top of the transparent pen inner tube. By rotating the top cap, the plug can be pulled out, making it easy to remove the top cap and the plug, thus exposing the opening at the top of the transparent pen inner tube and repeatedly injecting ink into the inside of the transparent pen inner tube.

[0016] When injecting ink into the inner tube of the transparent pen, unfold the cone-shaped pad, which forms a funnel-shaped structure. Insert the bottom of the cone-shaped pad into the inner tube of the transparent pen. The user holds the cone-shaped pad with one hand and injects ink with the other, making it convenient to add ink into the inner tube of the transparent pen.

[0017] 2. The pen cap and the transparent shell are connected by a threaded connection, which makes it easy to disassemble and assemble the pen cap and the transparent shell. The pen cap can be removed slightly to avoid paint splattering. Attached Figure Description

[0024] 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.

[0025] Example 1: Please refer to Figures 1-5 In existing highlighters, when the ink inside the transparent inner tube 2 is used up, it is inconvenient to refill the ink inside the transparent inner tube 2. Usually, the pen cap 7 is connected to the transparent outer shell 1 by plugging and unplugging. If too much force is used when plugging and unplugging, the ink on the highlighter tip 6 is easily splashed. In order to solve this technical problem, this embodiment discloses the following technical content.

[0026] A refillable highlighter includes a transparent outer shell 1, a transparent inner tube 2, a receiving ring 3, a blocking block 4, a top cap 5, a highlighter tip 6, a cap 7, an elastic rubber ring 8, and a conical pad 9. Figure 1 As shown, a transparent pen inner tube 2 is installed inside the transparent outer shell 1, and a receiving ring 3 is fixed to the inner wall of the top of the transparent pen inner tube 2. A blocking block 4 is attached to the top of the receiving ring 3. A top cover 5 is threaded to the top of the transparent outer shell 1. An elastic rubber ring 8 is provided on the outside of the transparent outer shell 1, and a conical pad 9 is provided on the inside of the elastic rubber ring 8.

[0027] When it is necessary to refill the inner tube 2 of the transparent pen with ink, rotate the top cap 5 to remove it from the top of the transparent outer shell 1, then pull out the plug 4 from the top of the inner tube 2, then remove the elastic rubber ring 8, and then unfold the conical pad 9, as shown. Figure 5 As shown, unfold the cone-shaped pad 9 into a funnel shape, then insert the bottom end of the cone-shaped pad 9 into the inside of the transparent pen tube 2, and then pour the paint into the inside of the transparent pen tube 2 through the cone-shaped pad 9 to prevent the paint from spilling out.

[0028] like Figure 1 and Figure 3As shown, the pen cap 7 is connected to the transparent shell 1 by a threaded connection. By manually rotating the pen cap 7 slightly, it can be removed from the transparent shell 1 to avoid the connection getting stuck and causing paint to splatter.

[0029] The above completes a series of operations for the refillable pigment highlighter. Any content not described in detail in this instruction is prior art known to those skilled in the art.
