Description

Technical Field

[0001] This utility model relates to the field of writing instruments technology, and in particular to a round pen. Background Technology

[0002] Round pens are a common type of writing instrument, and their appearance and decorative features are increasingly valued by consumers.

[0003] Existing round pen heat transfer printing technology suffers from problems such as monotonous patterns and lack of three-dimensionality, making it difficult to meet consumers' demand for personalized, high-quality stationery. Moreover, the printed ink patterns are prone to peeling off and have poor durability. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a holographic circular pen that can provide decorative patterns with a three-dimensional visual effect and is not easily smudged.

[0005] A holographic circular pen according to an embodiment of the present invention includes: a pen barrel having a cylindrical wall; a heat transfer adhesive layer cured on the outer side of the cylindrical wall; an aluminum plating layer attached to the outer side of the heat transfer adhesive layer; a molding layer, which is transparent and formed on the outer side of the aluminum plating layer, the inner side of the molding layer having a microstructure texture; a transparent ink pattern layer printed on the outer side of the molding layer; and a release agent layer, which is transparent and cured on the outer side of the transparent ink pattern layer.

[0006] The product offers at least the following benefits: The cylindrical pen features a heat transfer adhesive layer, an aluminum plating layer, a molding layer, a transparent ink pattern layer, and a release agent layer sequentially arranged on the outer side of the cylindrical wall. The heat transfer adhesive layer provides adhesion, the aluminum plating layer offers excellent reflectivity and a metallic sheen, and a metal template with special optical effects is created using laser holographic lithography. This template is then used for molding, resulting in a microstructure texture on the molding layer. This microstructure texture provides refractive interfaces at different angles, creating a visually three-dimensional effect. The transparent ink pattern layer has low opacity, and the combined luster of the transparent ink and the aluminum plating layer reflects vibrant pattern colors. When consumers observe the cylindrical wall from different angles or under different light sources, the hue and brightness of the pattern show noticeable changes, achieving a three-dimensional visual effect. The release agent layer protects the transparent ink pattern layer, preventing ink smudging and improving the product's durability. This design effectively meets consumers' needs for personalized decoration of the cylindrical pen.

[0007] According to some embodiments of the present invention, the heat transfer adhesive layer, the aluminum plating layer, the molding layer, the transparent ink pattern layer, and the release agent layer are arranged around the cylindrical wall in a half-circumference to a full-circumference.

[0008] According to some embodiments of the present invention, a PET film is attached to the outer side of the release agent layer.

[0009] According to some embodiments of the present invention, the thickness of the PET film is 10~20μm.

[0010] According to some embodiments of the present invention, the molded layer is formed by resin curing.

[0011] According to some embodiments of this utility model, the thickness of the molded layer is 1~5μm.

[0012] According to some embodiments of this utility model, the thickness of the heat transfer adhesive layer is 1~2μm.

[0013] According to some embodiments of the present invention, the inner side of the molded layer is formed by aluminum evaporation cooling and corona treatment to form the aluminum plating layer.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] In the description of this utility model, it should be understood that the orientation descriptions, such as inner and outer, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Reference Figure 1 andFigure 2 This utility model discloses a holographic lithography circular pen, including a pen barrel 1, a heat transfer adhesive layer 2, an aluminum plating layer 3, a molding layer 4, a transparent ink pattern layer 5, and a release agent layer 6.

[0022] Among them, reference Figure 1 The pen barrel 1 has a cylindrical wall 11, which can be located in the middle section of the pen barrel 1.

[0023] Reference Figure 2 A heat transfer adhesive layer 2, an aluminum plating layer 3, a molding layer 4, a transparent ink pattern layer 5, and a release agent layer 6 are sequentially disposed on the outer side of the cylindrical wall 11. The heat transfer adhesive layer 2 is cured on the outer side of the cylindrical wall 11 and provides adhesive adhesion. The aluminum plating layer 3 is attached to the outer side of the heat transfer adhesive layer 2 and has good reflectivity and provides a metallic luster base color.

[0024] The molding layer 4 is transparent and is formed on the outside of the aluminum-plated layer 3. The inner side of the molding layer 4 has a microstructure texture 41. A metal template with special optical effects is made using laser holographic lithography technology. The metal template is used for molding to obtain the microstructure texture 41 on the molding layer 4. The microstructure texture 41 provides a refractive interface at different angles, forming a visual three-dimensional effect.

[0025] The transparent ink pattern layer 5 is printed on the outside of the molding layer 4. The transparent ink pattern layer 5 has low opacity. The gloss of the transparent ink and the gloss of the aluminum plating layer 3 are combined to reflect a more vivid pattern color. When consumers observe the cylindrical wall 11 from different angles or under different light sources, the hue and brightness of the pattern will change significantly, achieving a three-dimensional visual effect.

[0026] The release agent layer 6 is transparent and is cured on the outside of the transparent ink pattern layer 5. The release agent layer 6 can protect the transparent ink pattern layer 5, prevent ink from falling off, and improve the durability of the product, thereby meeting consumers' demand for personalized decoration of round pens.

[0027] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The heat transfer adhesive layer 2, the aluminum plating layer 3, the molding layer 4, the transparent ink pattern layer 5, and the release agent layer 6 surround the cylindrical wall 11 in a half-circle to a full circle, usually around a full circle, to increase the surface area and prevent them from overlapping.

[0028] In some embodiments, the molding layer 4 is formed by resin curing, the thickness of the molding layer 4 can be configured to be 1~5μm, the thickness of the heat transfer adhesive layer 2 can be configured to be 1~2μm, and the inner side of the molding layer 4 can be formed by aluminum evaporation cooling and corona treatment to form an aluminum plating layer 3.

[0029] In the manufacturing process, a transfer film needs to be prepared as a carrier. Specifically, a PET film 7 with heat and pressure resistance can be used. First, a release agent is coated on the front side of the PET film 7 and cured to form a release agent layer 6. Alternatively, a PET film 7 with a release agent layer 6 can be prepared directly. Then, a transparent ink pattern layer 5 is printed on the front side of the release agent layer 6. After that, resin is coated on the front side of the transparent ink pattern layer 5 and cured. A metal template with special optical effects is made using laser holographic lithography technology. The resin is molded through the metal template to obtain a molding layer 4 with microstructure texture 41. The front side of the molding layer 4 is cooled by aluminum evaporation and corona treatment to form an aluminum plating layer 3. Then, a heat transfer adhesive is coated on the front side of the aluminum plating layer 3. Finally, the entire front side of the PET film 7 is attached around the outside of the cylindrical wall 11. The pen barrel 1 is heated and pressurized using a heat transfer machine. After the heat transfer adhesive is cured to form a heat transfer adhesive layer 2, the pattern and the cylindrical wall 11 are firmly fused together, completing the manufacturing process.

[0030] Reference Figure 2 Although PET film 7 is used as a transfer carrier during the manufacturing process, after the manufacturing is completed, PET film 7 can be left on the outside of the release agent layer 6 without being removed. PET film 7 can protect the pattern during packaging, storage, transportation and sales. When consumers use it, PET film 7 can be easily removed. The thickness of PET film 7 can be configured to be 10~20μm.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] Of course, this utility model is not limited to the above-described embodiments.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
