Description

Technical Field

[0001] This utility model relates to the field of stationery, specifically to a refillable glue pen. Background Technology

[0002] Common adhesive tools in stationery typically include solid glue sticks and liquid glue. Solid glue sticks, because they don't flow, are less prone to over-application compared to liquid glue, making them ideal for children to use. However, solid glue sticks also have drawbacks, such as a shorter shelf life and relatively weaker bonding strength. Furthermore, their cylindrical shape makes it difficult to control the application area, especially at the edges.

[0003] Regular liquid glue is relatively difficult for children to use, as they are prone to applying too much, making it difficult for the objects to bond quickly enough. Even for adults, liquid glue is prone to pooling. During bonding, glue may overflow, causing dirt and grime at the edges of the bonded area. Utility Model Content

[0053] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] Please see Figures 1-6 This application provides the following technical solutions:

[0055] A refillable glue pen includes a pen barrel 1, a pen tip 3, and a pen cap 4. The pen barrel 1 has an internal cavity and a drainage assembly. A capsule 2 filled with liquid glue can be placed in the cavity inside the pen barrel 1. The pen tip 3 is located at one end of the pen barrel 1, and the pen tip 2 communicates with the capsule 2 inside the pen barrel 1. The glue in the capsule 2 can flow to the pen tip 3 through the drainage assembly. The pen cap 4 covers the outside of the pen tip 3 and is connected to the pen barrel assembly 1.

[0056] The pen barrel 1 can be divided into a capsule section 11 and a drainage section 12. The capsule section 11 has a cavity inside which the capsule 2 can be placed. The drainage section 12 and the capsule section 11 are detachably connected, and the inside of the drainage section 12 is connected to the inside of the capsule section 11. The drainage component is set inside the drainage section 12, and the pen tip 3 is connected to the end of the drainage section 12 away from the capsule section 11.

[0057] The drainage section 12 is provided with a pen tip connector with an approximately conical cylindrical body at its end. The pen tip connector is a hollow sleeve structure. The pen tip connector and the outer wall of the drainage section 12 are detachably connected. The pen tip 3 is set inside the pen tip connector. The pen tip connector is designed to prevent the pen tip 3 from detaching from it.

[0058] This innovative solution uses a capsule-like structure to store liquid adhesive. When not in use, the capsule is in a closed storage state, greatly extending the adhesive's shelf life. With the help of the diversion component and the pen tip, the pen tip serves as the adhesive application structure, making it easier to control and observe the application area. This significantly improves the convenience of detailed adhesive application operations.

[0059] Based on the above implementation plan, see Figures 6 to 10 The drainage assembly includes a regulator 13 and a water-guiding core 14. The regulator 13 is located inside the drainage section 12 and is used to control the amount of fluid output from the capsule 2. The water-guiding core 14 is sleeved inside the regulator 13. Both ends of the water-guiding core 14 extend to the outside of the regulator 13, one end is connected to the pen tip 3, and the other end extends into the capsule 2.

[0060] The water-guiding core 14 works in conjunction with the regulator 13 to guide a limited amount of glue from the capsule 2 to the pen tip 3, allowing the pen tip 3 to apply glue without excessive overflow.

[0061] See Figures 11 to 13The regulator 13 includes an regulating body 131, which has a through-flow channel inside. The through-flow channel is parallel to the length direction of the pen barrel 1. A fin assembly is arranged around the regulating body 131, consisting of several annular fins distributed along the length direction of the regulating body 131. An annular space is left between adjacent fins, forming an annular groove structure that communicates with the flow channel. The groove width of the annular groove between the fins gradually changes, with the groove width near the second connecting part 133 being greater than the groove width near the first connecting part 132.

[0062] A first connecting part 132 and a second connecting part 133 are respectively provided at both ends of the adjusting body 131. The first connecting part 132 is located at the end of the adjusting body 131 facing the pen tip 3, and the pen tip 3 is in contact with the first connecting part 132. The second connecting part 133 is located at the other end of the adjusting body 131. The second connecting part 133 can be inserted into the bladder tube 2. The drainage channel passes through the first connecting part 132 and the second connecting part 133. The two ends of the water guide core 14 extend to the outside of the first connecting part 132 and the second connecting part 133, respectively.

[0063] With this structure, the end of the capsule 2 is punctured by the second connecting part 133 and the water-guiding core 14. Then, the ends of the second connecting part 133 and the water-guiding core 14 extend into the capsule 2 and come into contact with the glue. The glue enters the adjusting body 131 from the second connecting part 133 and simultaneously flows into the pen tip 3 along the water-guiding core 14, and finally flows out from the pen tip 3. The glue entering the adjusting body 131 is blocked by the adjusting body 131, ensuring that it can fully contact and drain the water-guiding core 14 inside, but without excessively flowing into the pen tip 3 along the water-guiding core 14.

[0064] Based on the above implementation scheme, a first slot 134, a second slot 135, and a third slot 136 are respectively provided on the adjusting body 131. See Figure 11 and Figure 13 The first slot 134 is formed on one side of the fin assembly, and the length direction of the first slot 134 is parallel to the length direction of the pen barrel 1; the first slot 134 is connected to the drainage channel inside the adjusting body 131. The first slot 134 is connected to the annular groove. The first slot 134 extends all the way to the second connecting part 133, and it passes through the end of the second connecting part 133 toward the capsule tube 2.

[0065] The second slot 135 is located on the other side of the fin assembly, opposite to the first slot 134; the width of the second slot 135 is greater than the width of the first slot 134. (See also...) Figure 12The second slot 135 and the drainage channel inside the regulating body 131 are not connected, and the second slot 135 is not a continuous slot on the regulating body 131, but rather has a partition in the middle. At least two connecting holes are provided between the first slot 134 and the drainage channel, corresponding to the two partitioned portions of the second slot 135. It should be noted that the partition structure in the middle of the second slot 135 does not completely isolate the second slot 135; the partition is equivalent to half the depth of the second slot 135.

[0066] See Figure 12 A third slot 136 is formed on the second connecting portion 133, located on the side of the second connecting portion 133 opposite to the first slot 134; the third slot 136 extends to the end of the second connecting portion 133 facing the tube 2. Both the first slot 134 and the third slot 136 on the second connecting portion 133 are connected to the drainage channel inside the second connecting portion 133. The third slot 136 and the second slot 135 are not directly connected, but are blocked by a baffle at the end of the adjusting body 131. Through the related structure of the adjusting body 131 in this solution, the glue can be well drained and adjusted, effectively controlling the glue output to the pen tip 3 at a suitable application amount.

[0067] Based on the above implementation scheme, the water core 14 is a long strip structure with pointed ends at both ends. One end abuts against the pen tip 3, while the other end protrudes slightly to the outside of the second connecting part 133.

[0068] The water-guiding core 14 can be made of different materials. Option 1 is to make it of fiber material. If fiber material is used, the glue can be guided by the properties of the fiber material itself.

[0069] Option two involves injection molding using ABS material. This material requires a drainage structure. This option provides a drainage structure configuration for the water inlet core 14, see [link / reference]. Figure 8 and Figure 10 A slit 141 is provided on each side of the water-guiding core 14, the length of which corresponds to the length of the water-guiding core 14. A long groove 142 is provided in the middle of one of the slits 141. The long groove 142 is a recessed groove, and its two ends are connected to the slit 141 on the side it is located on. With this structure, sufficient water can be guided to the pen tip 3.

[0070] Based on the above implementation plan, the pen tip 3 can be set in different shapes, such as round tip, pointed tip, flat tip, etc., and can be changed according to the target group of the product to achieve different applicable scenarios.

[0071] Based on the above implementation plan, see Figures 1 to 3The pen cap 4 includes a cover 41 and a protrusion 42. The cover 41 only needs to be able to cover the outside of the pen tip 3 and simultaneously cover the outside of the dispensing part 12. The protrusion 42 is located at the end of the cover 41 away from the pen barrel 1, and the protrusion 42 is a raised platform with ridged edges. The protrusion 42 forms a long, ridged structure, which allows the glue pen to be used in more ways and enriches its functionality. For example, the protrusion 42 can be used for gold foil stamping, pressing the adhesive joint, scratching, etc., and the user can use it according to actual needs.
