Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box technology, specifically to a waterproof wax-coated cardboard box. Background Technology
[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes are usually used as wrapping materials for goods or as outer protective materials for items. The volume of cardboard boxes varies depending on the size of the goods.
[0003] Cardboard boxes are widely used nowadays. After storing items, cardboard boxes can get wet in severe weather, causing them to become waterlogged. This can reduce the cardboard's rigidity, making it more prone to breakage and potentially damaging the items inside. To address this, we propose a waterproof wax-coated cardboard box. Utility Model Content
[0004] In view of the problems existing in the current cardboard boxes, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a waterproof wax-coated cardboard box, which solves the problem that the cardboard box will be soaked in water when it comes into contact with rainwater in bad weather.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A waterproof wax-coated cardboard box includes a cardboard box body, with flaps fixedly provided at the top and bottom of the cardboard box body, and creases fixedly provided at the connection between the flaps and the cardboard box body. A fixing groove is fixedly provided inside the cardboard box body and the flaps, and a support body is fixedly provided within the fixing groove in a triangular shape. A film is fixedly provided on the outer wall of the cardboard box body and the flaps, and spray nozzles are fixedly provided on both side walls of the film. A fixing plug is fixedly provided at each spray nozzle.
[0008] Preferably, a telescopic frame is fixedly installed inside the carton, and the two ends of the telescopic frame are rotatably connected to the inner side wall of the carton body.
[0009] Preferably, handles are fixedly provided on both sides of the carton body.
[0010] Preferably, the telescopic frame is a paper frame.
[0011] Furthermore, the carton body is made of corrugated cardboard.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] This invention utilizes a thin film to ensure more even application of waterproof wax. To prevent the cardboard box from getting wet in severe weather, the waterproof wax is sprayed into the film through the spray nozzle. The film allows the waterproof wax to be applied more evenly to the surface of the cardboard box, increasing its rigidity and preventing it from being easily damaged, thus ensuring the integrity of the items inside. An extendable frame is installed inside the cardboard box to effectively separate the items and prevent them from colliding. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0021] This utility model discloses a waterproof wax-coated cardboard box.
[0022] This utility model provides, for example Figure 1-3The waterproof wax spray-coated cardboard box shown includes a cardboard box body 1. Folds 2 are fixedly provided at the top and bottom of the cardboard box body 1. A crease 3 is fixedly provided at the connection between the folds 2 and the cardboard box body 1. A fixing groove 4 is fixedly provided inside the cardboard box body 1 and the folds 2. A support body 5 is fixedly provided within the fixing groove 4 in a triangular shape. A film 6 is fixedly provided on the outer wall of the cardboard box body 1 and the folds 2. Spray nozzles 7 are fixedly provided on both sides of the film 6. A fixing plug 8 is fixedly provided at each spray nozzle 7. Waterproof wax is sprayed into the film 6 through the spray nozzles 7. The film 6 allows the waterproof wax to be applied more evenly to the surface of the cardboard box, increasing the rigidity of the cardboard box and preventing it from being easily damaged.
[0023] For objects to collide, such as Figure 1 As shown, a telescopic frame 9 is fixedly installed inside the cardboard box. The two ends of the telescopic frame 9 are rotatably connected to the inner side wall of the cardboard box body 1. The telescopic frame 9 is installed inside the cardboard box and can effectively separate the items inside the cardboard box to prevent the items from colliding.
[0024] To facilitate the handling of cardboard boxes, such as Figure 3 As shown, handles 10 are fixed on both sides of the carton body 1 for easy handling of the carton.
[0025] To make cardboard boxes lighter, such as Figure 1-3 As shown, the telescopic frame 9 uses a paper frame to make the cardboard boxes lighter.
[0026] Finally, to make the outside of the cardboard box more sturdy, such as Figure 1-3 As shown, the carton body 1 is made of corrugated cardboard to make the exterior of the carton more robust.
[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
