Description

Technical Field

[0001] This utility model relates to the field of gift packaging box technology, specifically a packaging paper box for storing gifts. Background Technology

[0002] In modern society, gift packaging boxes are widely used for packaging various gifts. Gift packaging not only protects the gifts but also enhances their aesthetics and perceived quality. However, existing gift packaging boxes have some shortcomings in their use.

[0003] First, regarding the handling of gifts, traditional gift boxes can be inconvenient for gifts that are placed deep inside or are large in size. Users may have to reach out or tip the box, which can easily damage the gift or cause inconvenience to the user.

[0004] Secondly, regarding the opening and closing of the box lid, many cardboard boxes use a simple flip-top structure, secured by clips or glue. After repeated opening and closing, the clips tend to loosen, preventing the lid from closing tightly and affecting the packaging's airtightness and aesthetics. Furthermore, some clip designs are flawed, requiring considerable force to open and close, causing inconvenience to users.

[0005] Furthermore, waterproof performance is a crucial factor to consider when designing gift boxes. Most existing boxes are made of ordinary paper and lack waterproofing. In humid environments or if accidentally exposed to water, moisture can easily seep into the box, causing the gift to become damp and damaged. This is especially true for moisture-sensitive gifts such as chocolates and tea, where insufficient waterproofing can severely impact the gift's quality and shelf life.

[0006] Finally, regarding structural strength, traditional gift packaging boxes, in pursuit of lightness and cost-effectiveness, often use thinner paper materials and have simple structural designs. During transportation and storage, these boxes are easily subjected to external forces such as squeezing and collisions, leading to deformation and damage, and failing to effectively protect the gifts. Especially for some valuable gifts, insufficient structural strength can cause serious losses.

[0007] In conclusion, existing gift packaging boxes have room for improvement in terms of gift handling convenience, lid opening and closing ease, waterproof performance, and structural strength. Therefore, a new type of gift packaging box needs to be designed to solve these problems. Utility Model Content

[0008] To address the problems mentioned in the background section, the present invention aims to provide a packaging box for storing gifts, which is easy to use.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a gift packaging box, comprising a box body, a lid hinged to the back of the top of the box body, a nylon rope fixedly connected to the front of the lid, a cylindrical block fixedly connected to the end of the nylon rope away from the lid, a winding reel fixedly connected to the front of the box body, a groove provided on the front of the box body, a fixing strip fixedly connected inside the groove, a sliding groove provided on the front of the fixing strip, sliders slidably connected to both sides of the sliding groove, the two sliders being in contact with each other, and a compression spring fixedly connected to both sides of the inner wall of the sliding groove, the end of the compression spring away from the sliding groove being fixedly connected to the slider, a first locking block fixedly connected to the front of the left slider, and a second locking block fixedly connected to the front of the right slider, the first locking block and the second locking block being in contact, a semi-circular groove provided on the top of both the first locking block and the second locking block, the diameter of the semi-circular groove being the same as the diameter of the nylon rope, and the diameter of the nylon rope being smaller than the diameter of the cylindrical block.

[0010] As a preferred embodiment of this invention, the box body is provided with a storage rack inside.

[0011] As a preferred embodiment of this utility model, the top of the box is provided with an installation groove, and a sealing strip is fixedly connected inside the installation groove, the sealing strip being fitted to the cover.

[0012] As a preferred embodiment of this utility model, a connecting strap is fixedly connected to both sides of the lid, and a pressing buckle is fixedly connected to the end of the connecting strap away from the lid. A pressing female buckle is fixedly connected to both sides of the box body, and the pressing buckle and the pressing female buckle are engaged.

[0013] As a preferred embodiment of this utility model, handles are fixedly connected to both sides of the top of the cover, the surface of the compression spring is coated with anti-rust paint, a limit rod is fixedly connected to the right side of the first locking block, and the limit rod is slidably connected to the second locking block.

[0014] As a preferred embodiment of this utility model, both the box body and the lid include a cardboard layer, a corrugated paper layer is fixedly connected to the surface of the cardboard layer, a kraft paper layer is fixedly connected to the surface of the corrugated paper layer, and a waterproof coating is sprayed onto the surface of the kraft paper layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model employs a hinged lid on the back of the top of the box, combined with a nylon rope and cylindrical block on the front of the lid, as well as a winding reel, fixing strip, sliding groove, slider, compression spring, first locking block, and second locking block on the front of the box. This effectively improves the ease of use of the packaging box and the locking effect of the lid. The hinged lid design makes the opening and closing action smoother. The nylon rope connects the lid and the cylindrical block, allowing the user to hold the cylindrical block and pull it forward, causing the nylon rope to separate from the semi-circular groove. During this process, the nylon rope overcomes the elasticity of the compression spring, causing the first locking block and the second locking block to move away from each other. Then, the nylon rope wrapped around the surface of the winding reel is unwound, thus opening the lid. The semi-circular groove matches the diameter of the nylon rope, effectively clamping and fixing the nylon rope to prevent accidental opening of the lid. Furthermore, the diameter of the nylon rope is smaller than the diameter of the cylindrical block, which acts as a limit to prevent the nylon rope from coming out of the semi-circular groove, ensuring the stability of the lid's locking mechanism. The structure is reasonably designed and easy to operate, effectively solving the problems of inconvenient opening and closing and poor locking of traditional cardboard box lids. The device is easy to use.

[0017] 2. This utility model features a placement rack inside the box, which plays a crucial role. The rack can be designed according to the shape and size of the gift and can also be used in conjunction with protective foam board. It provides excellent support, fixation, and protection for the gifts inside the box, preventing them from shifting around and reducing collisions with the box's inner wall during transportation or storage, thus lowering the risk of damage. When a user needs to retrieve a gift from the box, they don't need to laboriously rummage through or tilt the box; the operator simply moves the placement rack upwards to lift the gift, making it easy to remove and significantly improving convenience.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 7 As shown, a gift box includes a box body 1, a lid 2 hinged to the back of the top of the box body 1, a nylon rope 3 fixedly connected to the front of the lid 2, a cylindrical block 4 fixedly connected to the end of the nylon rope 3 away from the lid 2, a winding reel 5 fixedly connected to the front of the box body 1, a groove provided on the front of the box body 1, a fixing strip 6 fixedly connected inside the groove, a sliding groove provided on the front of the fixing strip 6, and sliders 7 slidably connected to both sides of the sliding groove, with the two sliders 7 fitting together, and a compression spring 8 fixedly connected to both sides of the inner wall of the sliding groove, with the end of the compression spring 8 away from the sliding groove fixedly connected to the slider 7, a first locking block 9 fixedly connected to the front of the left slider 7, and a second locking block 10 fixedly connected to the front of the right slider 7, with the first locking block 9 fitting together with the second locking block 10, and a semi-circular groove 12 provided on the top of both the first locking block 9 and the second locking block 10, the diameter of the semi-circular groove 12 being the same as the diameter of the nylon rope 3, and the diameter of the nylon rope 3 being smaller than the diameter of the cylindrical block 4.

[0028] refer to Figure 2 The box 1 has a shelf 17 inside.

[0029] As a technical optimization of this utility model, the placement rack 17, located inside the box body 1, plays a crucial role. The placement rack 17 can be designed according to the shape and size of the gift, and can also be used in conjunction with protective foam board. It provides excellent support, fixation, and protection for the gift inside the box, preventing it from shifting around and reducing collisions between the gift and the inner wall of the box body 1 during transportation or storage, thus lowering the risk of damage. When a user needs to retrieve a gift from the box body 1, they do not need to laboriously rummage through or tilt the box; the operator simply needs to move the placement rack 17 upwards to lift the gift from the box body 1, facilitating easy retrieval and significantly improving convenience.

[0030] refer to Figure 5 The top of the box 1 is provided with an installation groove, and a sealing strip 16 is fixedly connected inside the installation groove. The sealing strip 16 fits against the cover 2.

[0031] As a technical optimization of this utility model, the sealing strip 16, which is fixedly connected to the top mounting groove of the box body 1, adheres to the lid 2, significantly improving the sealing performance of the packaging box. The sealing strip 16 is made of elastic material. When the lid 2 is closed, the sealing strip 16 fits tightly against the bottom of the lid 2, forming an effective sealing barrier to prevent external dust and moisture from entering the box body 1, thus providing excellent protection for the gifts inside. This is especially beneficial for moisture-sensitive gifts such as chocolates and tea, effectively preventing them from spoiling due to moisture. Simultaneously, the sealing strip 16 enhances the fit between the lid 2 and the box body 1, making the lid 2 close more tightly and reducing sealing failures caused by a loose lid 2, thereby improving the overall performance of the packaging box.

[0032] refer to Figure 5 Both sides of the lid 2 are fixedly connected with connecting straps 13. The end of the connecting strap 13 away from the lid 2 is fixedly connected with a pressing buckle 14. Both sides of the box body 1 are fixedly connected with pressing nuts 15. The pressing buckle 14 and the pressing nuts 15 are engaged.

[0033] As a technical optimization of this utility model, the opening and closing method of the lid 2 is optimized by connecting the connecting strips 13 on both sides of the lid 2, the pressing buckles 14, and the pressing female buckles 15 on both sides of the box body 1. The connecting strips 13 have a certain degree of elasticity and toughness, which can buffer the impact force of the lid 2 on the box body 1 during opening and closing, and reduce the wear of the parts. The pressing buckles 14 and the pressing female buckles 15 adopt a pressing-type snap-fit ​​structure, which is easy to operate. The user only needs to press lightly to connect or separate the buckles and the female buckles. Compared with the traditional buckle structure, it is less labor-intensive and reduces the difficulty of opening and closing. Moreover, this structure has undergone multiple opening and closing tests and is not prone to loosening. It can maintain a good snap-fit ​​effect for a long time, ensuring the stability of the connection between the lid 2 and the box body 1. It effectively solves the problem of loosening and the lid not being able to close tightly after multiple opening and closing of traditional cardboard box buckles. The connecting strips 13, the pressing buckles 14, and the pressing female buckles 15 on both sides of the box body 1 mainly play the role of assisting in fixing the lid 2, thereby improving the stability of fixing the lid 2.

[0034] refer to Figure 1 Handles are fixedly connected to both sides of the top of the cover 2. The surface of the compression spring 8 is coated with anti-rust paint. A limit rod 11 is fixedly connected to the right side of the first locking block 9. The limit rod 11 is slidably connected to the second locking block 10.

[0035] As a technical optimization of this utility model, the handles on both sides of the top of the lid 2 facilitate user carrying of the packaging box. The handle design is ergonomic, providing a comfortable grip and reducing hand discomfort during carrying. The anti-rust paint sprayed on the surface of the compression spring 8 effectively prevents the compression spring 8 from rusting due to moisture or air contact, extending the service life of the compression spring 8 and ensuring the stability of the elastic performance of the compression spring 8. This, in turn, ensures the smooth sliding of the slider 7 in the groove and the clamping effect of the first locking block 9 and the second locking block 10. The limiting rod 11 fixedly connected to the right side of the first locking block 9 is slidably connected to the second locking block 10, preventing misalignment of the first locking block 9 and the second locking block 10 during the fitting process. This ensures accurate alignment of the semi-circular grooves 12 at the top of both, effectively improving the stability and reliability of the nylon rope 3 clamping, and making the locking structure of the packaging box more durable.

[0036] refer to Figure 4 Both the box body 1 and the lid 2 include a cardboard layer 18, a corrugated paper layer 19 is fixedly connected to the surface of the cardboard layer 18, a kraft paper layer 20 is fixedly connected to the surface of the corrugated paper layer 19, and a waterproof coating 21 is sprayed onto the surface of the kraft paper layer 20.

[0037] As a technical optimization of this utility model, the multi-layer structure of the box body 1 and lid 2, consisting of cardboard layer 18, corrugated paper layer 19, kraft paper layer 20, and waterproof coating 21, significantly improves the structural strength and waterproof performance of the packaging box. Cardboard layer 18 serves as the base layer, providing basic structural support; corrugated paper layer 19 has good compression resistance and cushioning properties, effectively enhancing the compression resistance of box body 1 and lid 2, reducing deformation or damage caused by external forces during transportation and storage. Kraft paper layer 20 has a smooth surface and good texture, enhancing the aesthetics of the packaging box; the waterproof coating 21, sprayed on the surface of kraft paper layer 20, effectively prevents moisture penetration, making the packaging box less prone to water absorption and deformation in humid environments or when in contact with water, thus extending its service life. The synergistic effect of the multiple materials allows the packaging box to effectively protect gifts while possessing a good appearance and durability.

[0038] The working principle and usage process of this utility model are as follows: First, open the packaging box. The user stands in front of the box and holds the handles on both sides of the top of the lid 2 with both hands. The ergonomic design of the handles ensures comfortable grip and reduces hand fatigue. Then, pinch the cylindrical block 4 with the thumb and forefinger of one hand. Since the end of the nylon rope 3 furthest from the lid 2 is fixedly connected to the cylindrical block 4, and the diameter of the nylon rope 3 is smaller than the diameter of the cylindrical block 4, the cylindrical block 4 acts as a limit, preventing the nylon rope 3 from slipping out of the semi-circular groove 12. Pull the cylindrical block 4 forward. At this time, the nylon rope 3 will be under tension. Since the top of the first locking block 9 and the second locking block 10 are both provided with semi-circular grooves 12 with the same diameter as the nylon rope 3, the nylon rope 3 is initially engaged in the semi-circular grooves 12. During the pulling process, the nylon rope 3 will exert an outward pushing force on the first locking block 9 and the second locking block 10, causing the two mutually attached sliders 7 to slide in the groove. The compression springs 8 on both sides of the inner wall of the groove are compressed and store elastic potential energy. The first locking block 9 and the second locking block 10 gradually move away from each other until the nylon rope 3 separates from the semi-circular groove 12. Next, unwrap the nylon rope 3 wrapped around the surface of the take-up reel 5, and then pull the pressing buckle 14 to both sides until the pressing buckle 14 separates from the pressing nut 15. Since the cover 2 is hinged to the back of the top of the box body 1, the cover 2 can be lifted upward to complete the opening action.

[0039] After opening lid 2, the shelf 17 inside box 1 is visible. To place a gift, the user can simply grasp the edge of shelf 17 and lift it upwards. Shelf 17 can be designed according to the shape and size of the gift and can also be used with protective foam board to provide good support, fixation, and protection for the gift inside the box. Place the gift on shelf 17, ensuring it is stable and preventing it from shaking inside the box. Then, slowly lower shelf 17 back into box 1, ensuring the bottom of shelf 17 is flush against the inner wall of box 1.

[0040] Next, close the lid 2. Place the lid 2 downwards on top of the box 1. At this time, the sealing strip 16 in the mounting groove at the top of the box 1 fits snugly against the lid 2. The sealing strip 16 is made of elastic material and can fit tightly against the bottom of the lid 2, forming an effective sealing barrier to prevent external dust, moisture, etc. from entering the interior of the box 1. The connecting straps 13 on both sides of the lid 2 hang down naturally. The end of the connecting strap 13 away from the lid 2 is fixedly connected to a pressing buckle 14. The sides of the box 1 are fixedly connected to pressing nuts 15. Align the pressing buckle 14 with the pressing nuts 15 and press gently to make the pressing buckle 14 and the pressing nuts 15 engage, which helps to fix the lid 2 and improves the stability of the lid 2.

[0041] Next, the nylon rope 3 is wound and locked. The nylon rope 3 on the front of the cover 2 is straightened and wound around the take-up reel 5, so that the nylon rope 3 is tightly wound around the surface of the take-up reel 5. During the winding process, the number of turns is fixed. At this time, the nylon rope 3 is tensioned and the cylindrical block 4 is pulled down. The top of the cylindrical block 4 is just below the first locking block 9 and the second locking block 10. After the winding is completed, the first locking block 9 and the second locking block 10 are separated. Then, the nylon rope 3 at the top of the cylindrical block 4 is placed between the two semi-circular grooves 12. Then, the first locking block 9 and the second locking block 10 are released. Under the action of the compression spring 8, the two sliders 7 move closer to each other until the first locking block 9 and the second locking block 10 are in contact with each other. At this time, under the limiting action of the cylindrical block 4, the nylon rope 3 wound around the surface of the take-up reel 5 will not loosen or unravel, thereby improving the stability of locking the cover 2 and preventing the cover 2 from opening accidentally.
