Abstract
Description
Technical Field
[0001] This application relates to the field of gift packaging boxes, and more particularly to a highly waterproof paper gift packaging box. Background Technology
[0002] Gift boxes are practical gift packaging primarily intended for giving gifts to relatives and friends to express affection. In addition to wrapping objects, gift boxes are generally exquisite and have a unique appearance, serving to decorate and enhance the item. They are widely used in interpersonal interactions today.
[0003] Chinese Patent Publication No. CN218778014U discloses a paper packaging gift box, including a bottom cardboard. A front cardboard and a rear cardboard are arranged sequentially from front to back on the upper part of the bottom cardboard. A top cover cardboard is positioned directly above the bottom cardboard. T-shaped grooves are symmetrically formed on the inner sidewalls of the front and rear sides of the top cover cardboard. T-shaped sliding rods are connected to the upper outer sides of both the front and rear cardboard, and these rods are slidably connected to the T-shaped grooves. However, existing devices have some shortcomings. Current packaging gift boxes are generally made of paper, resulting in poor water resistance. This makes the box prone to damage after absorbing moisture during use, thus affecting the contents inside. Therefore, we propose a paper packaging gift box with high water resistance to solve the above problems. Utility Model Content

[0012] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:
[0013] This utility model discloses a highly waterproof paper packaging gift box. By installing a waterproof component on the bottom surface of the box, water on the bottom surface of the box can be isolated from the box body. Furthermore, by installing a drainage component on the bottom surface of the waterproof component, water on the ground can be discharged through multiple sets of drainage protrusions, preventing water from accumulating on the bottom surface of the box and causing the box body to come into contact with water. Therefore, this device effectively solves the problem of poor waterproof performance of existing devices. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.
[0022] Please see Figure 1-4 This utility model provides a technical solution for a highly waterproof paper packaging gift box:
[0023] A highly waterproof paper gift box includes a box body 1. The outer surface of the box body 1 is provided with a carrying component 2, the bottom surface of the box body 1 is connected to a waterproof component 3, the bottom surface of the waterproof component 3 is equipped with a drainage component 4, and the upper surface of the waterproof component 3 is provided with a connecting component 6. The box body 1 includes an outer layer 10, a middle layer 11, and an inner layer 12. Specifically, the outer layer 10 is an environmentally friendly waterproof coating applied to the surface of the paper gift box, the middle layer 11 is a multi-layer composite paper and a biodegradable bioplastic layer, and the inner layer 12 is a lotus leaf effect biomimetic hydrophobic coating. In addition, the packaging gift box design can incorporate a folding process, and the waterproof component 3 at the bottom of the box body 1 can be folded into the box body 1, thereby folding the device to reduce the volume of the box body 1. This can significantly improve transportation efficiency, reduce costs, and enhance user experience. The waterproof coating can be made of white cardboard or gray-backed white board paper, which is economical and practical and suitable for surface lamination or coating treatment. The middle layer 11 can be made of corrugated paper, which is lightweight and pressure-resistant, but requires a waterproof process.
[0024] In this embodiment, the waterproof component 3 includes a bottom frame 5, which is located on the bottom surface of the box body 1. The bottom surface of the bottom frame 5 is provided with a waterproof reinforcement plate 14. The drainage component 4 includes multiple sets of drainage protrusions 7 and multiple support protrusions 8. Each set of drainage protrusions 7 and multiple support protrusions 8 are located on the bottom surface of the waterproof reinforcement plate 14. Specifically, the waterproof reinforcement plate 14 on the bottom surface of the bottom frame 5 can increase the waterproofness of the device, thereby preventing the box body 1 from contacting water. The drainage protrusions 7 allow water to flow from below the box body 1, and the support protrusions 8 can increase the support force of the device. The waterproof reinforcement plate 14 is a key detail for improving the durability, protection, and premium feel of the packaging, especially important in humid environments and for packaging heavy or high-value products. It can also distribute the weight of the contents. PVC rigid board or ABS engineering plastic can be selected. Its advantages are high rigidity, low cost, easy cutting and molding, impact resistance, surface coating and printing, and environmentally friendly upgrade. Materials with a thermal expansion coefficient close to that of the box body 1 are preferred to avoid deformation and cracking caused by temperature differences.
[0025] In this embodiment, the connecting component 6 includes an adhesive groove 9, which is located on the upper surface of the bottom frame 5, and the interior of the adhesive groove 9 is coated with adhesive. The carrying component 2 includes two handles 13, which are located on the front and back of the box body 1, respectively. Specifically, by opening the adhesive groove 9 on the upper surface of the bottom frame 5, the area between the adhesive and the bottom frame 5 and the box body 1 can be increased, thereby increasing the robustness of the device. The adhesive is a key material to ensure structural stability, aesthetics, and functionality. Its role goes far beyond simple pasting; it also affects user experience and environmental performance. Furthermore, the adhesive should be environmentally friendly and non-toxic. In actual use, the compatibility between the adhesive and printing ink needs to be tested. To prevent chemical reactions and fading, it is recommended to increase the amount of glue applied or choose a low-hygroscopic glue in high-humidity areas. Furthermore, handle 13 is not only a functional component but also a key element in enhancing user experience, brand image, and practicality. It increases the portability of the device, allowing consumers to easily carry gift boxes, especially suitable for larger or heavier packaging such as wine and food gift boxes. Customizing handle 13 can strengthen brand memory; its width should be greater than two centimeters to better distribute pressure, and the corners should be rounded to prevent cuts. Handle 13 should undergo a gravity test during installation and must be able to withstand three times the total weight of the gift box.
[0026] Working principle: When using this highly waterproof paper packaging gift box, the user first glues the box body 1 to the waterproof component 3 below to make the box body 1 waterproof. Then, when the box body 1 is placed on the ground, if water flows on the ground, the water can flow through the gaps between each drainage protrusion 7 in the drainage component 4, allowing the water to flow through the box body 1 and reducing the contact between the water and the box body 1.
[0027] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
