Description

Technical Field

[0001] This application relates to the technical field of ceiling decorative layers, and particularly to a layer structure of a container ceiling. Background Art

[0002] In the modern packaging industry, as a key component of a container, the design and manufacturing technology of the container ceiling have been continuously evolving to meet the market's multiple demands for aesthetics, practicality, and environmental protection. As the top structure of the container, the ceiling not only performs the function of protecting the items inside the container but also enhances the overall aesthetic of the container through its unique pattern design, attracting the attention of consumers.

[0003] Traditional container ceilings are usually made of a single material. Although they can meet basic usage requirements, they have many deficiencies in terms of aesthetics and durability. With the progress of technology and the improvement of consumers' aesthetics, the requirements for container ceilings are getting higher and higher.

[0004] Under the current background, in order to display the function of the container's contents and significantly enhance its aesthetics, the design of the container ceiling usually involves coating an adhesive on its surface and carefully fixing a delicate color picture film. This design not only makes the container more attractive but also endows it with unique visual charm. However, over time, due to the influence of environmental factors such as temperature and humidity on the color picture film, the four sides of the color picture film often curl, affecting the aesthetics of the container ceiling and the service life of the color picture film. Summary of the Utility Model

[0005] The purpose of this application is to solve the problem that over time, due to the influence of environmental factors such as temperature and humidity on the color picture film, the four sides of the color picture film often curl, affecting the aesthetics of the container ceiling and the service life of the color picture film. This application provides a layer structure of a container ceiling.

A customized color film is fixedly connected inside the installation groove. Film edges are fixedly connected to all four sides of the transparent BOPP film. A rectangular roller imprint is rolled at one end of the film edge.

[0008] By adopting the above technical solution, through the combined use of the film edge and the rectangular roller printing, the contact area between the film edge and the adhesive is effectively increased, and the four sides of the transparent BOPP film are driven by the film edge to be embedded into the contact end faces of the top plate and the packaging box, so that the four sides of the transparent BOPP film are clamped and fixed by the top plate and the packaging box, thereby effectively reducing the curling of the transparent BOPP film and improving the aesthetic appearance of the container top plate and the service life of the color picture film.

[0009] Further, the customized color film is set as a gilded color film.

[0010] By adopting the above technical solution, by processing the customized color film with the gilding process to form a gilded color film, the surface pattern of the customized color film effectively presents a metallic luster, thereby enhancing the visual effect on the surface of the customized color film.

[0011] Further, a plurality of exhaust holes are uniformly opened at one end of the film edge.

[0012] By adopting the above technical solution, through the combined use of the film edge and the exhaust holes, after the traction of the transparent BOPP film drives the film edge to adhere to the four sides of the top plate, by pressing the transparent BOPP film to fit with the top plate, and enabling the air bubbles remaining between the transparent BOPP film and the top plate to pass through the exhaust holes and be discharged, the practicality of the device is effectively improved.

[0013] Further, a polyethylene film is fixedly connected to the top of the transparent BOPP film, and the customized color film is installed between the transparent BOPP film and the polyethylene film.

[0014] By adopting the above technical solution, through the combined use of the polyethylene film and the transparent BOPP film, the moisture-proof and tear-resistant effects at the top of the transparent BOPP film are effectively improved.

[0015] Further, a pearlescent film is fixedly connected to the bottom of the transparent BOPP film.

[0016] By adopting the above technical solution, through the combined use of the pearlescent film and the transparent BOPP film, the gloss and appearance at the bottom of the transparent BOPP film are effectively improved.

[0017] Further, a plurality of raised strips are fixedly connected to the four sides of the bottom of the transparent BOPP film, and the raised strips are installed between the transparent BOPP film and the pearlescent film.

[0018] By adopting the above technical solution, through the combined use of the raised strips and the transparent BOPP film, the quality of the four sides of the transparent BOPP film is effectively improved, and further the toughness of the four sides of the transparent BOPP film is effectively improved.

[0019] Further, a gel edge wrapping is fixedly wrapped around the periphery of the transparent BOPP film and the pearlescent film.

[0020] By adopting the above technical solution, through the combined use of the gel edge and the transparent BOPP film and the pearlescent film, the four sides of the transparent BOPP film and the pearlescent film are effectively wrapped and protected, thereby further reducing the occurrence of curling of the transparent BOPP film and the pearlescent film.

[0021] Furthermore, a polyamide compatibilizer is fixedly connected inside the transparent BOPP film.

[0022] By adopting the above technical solution, through the combined use of the polyamide compatibilizer and the transparent BOPP film, the transparency and flexibility of the transparent BOPP film are effectively improved.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. By setting the combined use of the film edge and the rectangular roller imprint, the contact area between the film edge and the adhesive is effectively increased, and the four sides of the transparent BOPP film are driven by the film edge to be embedded in the contact end surface between the top plate and the packaging box, so that the four sides of the transparent BOPP film are clamped and fixed by the top plate and the packaging box, thereby effectively reducing the occurrence of curling of the transparent BOPP film and improving the aesthetic appearance of the container top plate and the service life of the color picture film.

[0025] 2. By setting the combined use of the film edge and the exhaust hole, after the transparent BOPP film is pulled to drive the film edge to adhere to the four sides of the top plate, by pressing the transparent BOPP film to fit with the top plate and enabling the air bubbles remaining between the transparent BOPP film and the top plate to pass through the exhaust hole and be discharged, the practicability of the device is effectively improved.

A customized color film 3 is fixedly connected inside the installation groove 2. Four sides of the transparent BOPP film 1 are all fixedly connected with film edges 4. One end of the film edge 4 is roll-pressed with a rectangular roller mark 5.

[0035] During use, first drive the transparent BOPP film 1 to bring the customized color film 3 closer to one side of the top board, and use an adhesive to bond the transparent BOPP film 1 with the customized color film 3 to one side of the top board. Then, pull the film edge 4 to deflect around the connection end with the transparent BOPP film 1, and at the same time make the film edge 4 fit with the four sides of the top board. Use the rectangular roller mark 5 to increase the contact area between the adhesive and the film edge 4, and drive the film edge 4 to form a fixed bond with the four sides of the top board, so as to facilitate the adhesion of the film edge 4 to the four sides of the top board, make the four sides of the transparent BOPP film 1 be embedded between the top board and the packaging box through the film edge 4, and then use the top board and the packaging box to clamp and fix the four sides of the transparent BOPP film 1, thereby effectively reducing the situation of the transparent BOPP film 1 curling up, and improving the aesthetics of the container top board and the service life of the color picture film.

[0036] Referring to Figure 1 and Figure 2 , the customized color film 3 is set as a hot stamping color film.

[0037] During use, by corona treating the transparent BOPP film 1, the adhesion on the surface of the transparent BOPP film 1 is improved. Then, use the hot stamping process to process the customized color film 3 into a hot stamping color film, so that the pattern on the surface of the customized color film 3 presents a metallic luster, improving the visual effect on the surface of the customized color film 3.

[0038] Referring to Figures 1-3 , a plurality of exhaust holes 6 are uniformly opened at one end of the film edge 4.

[0039] During use, when the transparent BOPP film 1 is adhered to one side of the top board through an adhesive, by pressing the transparent BOPP film 1, the air bubbles formed inside the transparent BOPP film 1 pass through the exhaust holes 6 and are discharged between the transparent BOPP film 1 and the top board, so as to facilitate the discharge of the air bubbles formed between the transparent BOPP film 1 and the top board, thereby improving the practicality of the device.

[0040] Referring to Figure 1 and Figure 2, a polyethylene film 7 is fixedly connected to the top of the transparent BOPP film 1, and the customized color film 3 is installed between the transparent BOPP film 1 and the polyethylene film 7.

[0041] When in use, by setting the polyethylene film 7 fixedly connected to the top of the transparent BOPP film 1, it is convenient to utilize the material characteristics of the polyethylene film 7, effectively improving the moisture-proof and tear-resistant effects of the top of the transparent BOPP film 1.

[0042] Refer to Figure 2 and Figure 4 , a pearlescent film 8 is fixedly connected to the bottom of the transparent BOPP film 1;

[0043] Among them, a plurality of raised strips 9 are fixedly connected to the four sides of the bottom of the transparent BOPP film 1, and the raised strips 9 are installed between the transparent BOPP film 1 and the pearlescent film 8;

[0044] Moreover, the periphery of the transparent BOPP film 1 and the pearlescent film 8 is fixedly wrapped with a gel edging 10.

[0045] When in use, first, the raised strips 9 are used to improve the quality of the four sides of the transparent BOPP film 1, thereby increasing the toughness of the four sides of the transparent BOPP film 1. Then, the pearlescent film 8 is tractioned and adhered to the bottom side of the transparent BOPP film 1 with an adhesive to improve the appearance of the bottom of the transparent BOPP film 1. Then, a fixing agent is used to wrap and fix the gel edging 10 around the four sides of the transparent BOPP film 1 and the pearlescent film 8, thereby further reducing the occurrence of curling of the transparent BOPP film 1 and improving the practicability of the device.

[0046] Refer to Figure 2 and Figure 4 , a polyamide compatibilizer 11 is fixedly connected to the inside of the transparent BOPP film 1.

[0047] When in use, it is convenient to utilize the material characteristics of the polyamide compatibilizer 11, effectively improving the flexibility and transparency of the transparent BOPP film 1.

[0048] The implementation principle of the layer structure of a container top plate in this embodiment is as follows: First, the transparent BOPP film 1 drives the customized color film 3 to approach the top plate side, and the transparent BOPP film 1 drives the customized color film 3 to be adhered to one side of the top plate with an adhesive. Then, the film edge 4 is tractioned to deflect around the connection end with the transparent BOPP film 1, and at the same time, the film edge 4 is made to fit the four sides of the top plate. The rectangular roller printing 5 is used to increase the contact area between the adhesive and the film edge 4, and the film edge 4 is driven to form a fixed adhesion with the four sides of the top plate. At the same time, the four sides of the transparent BOPP film 1 are embedded between the top plate and the packaging box through the film edge 4, and then the top plate and the packaging box are used to clamp and fix the four sides of the transparent BOPP film 1;

[0049] Then, by pressing the transparent BOPP film 1, the bubbles formed inside the transparent BOPP film 1 pass through the vent 6 and are discharged from between the transparent BOPP film 1 and the top plate. Then, the pearlescent film 8 is pulled and adhered to the bottom side of the transparent BOPP film 1 with an adhesive to improve the appearance of the bottom of the transparent BOPP film 1. Then, the gel edge wrapping 10 is wrapped and fixed to the four sides of the transparent BOPP film 1 and the pearlescent film 8 using a fixing agent, thereby further reducing the curling of the transparent BOPP film 1.
