Description

Technical Field

[0001] This utility model relates to the field of packaging, and in particular to a packaging box with a cushioning interlayer. Background Technology

[0002] Packaging boxes play a crucial role in protecting the contents from damage during the transportation and storage of various products. However, traditional packaging boxes often suffer from insufficient cushioning or poor structural stability.

[0003] Current conventional packaging boxes rely solely on a single cushioning material or a simple structural design for protection. When subjected to external forces such as collisions or vibrations, they are unable to effectively absorb impact energy, easily leading to damage to the contents. Furthermore, the connection between the box body and lid in some packaging boxes is not tight enough, potentially causing the lid to detach during handling, further reducing the protective effect on the items.

[0004] Furthermore, some packaging boxes lack effective restraint designs in their internal structures for placing cushioning materials, making the cushioning material prone to shifting within the box and failing to maintain stable containment of the items, thus affecting the continuity and reliability of cushioning protection. Moreover, some improperly designed restraint structures may even cause additional puncture or crush damage to the items when subjected to external forces. Therefore, a packaging box with a cushioning interlayer is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the above problems and meet the packaging requirements of efficient protection of items, stable structure and convenient assembly. It is particularly necessary to develop a packaging box with a double buffer structure and a stable connection and limiting design.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging box with a cushioning interlayer, comprising a packaging box body, a packaging box lid sleeved onto the upper end of the packaging box body, a cushioning material frame embedded inside the packaging box body, and a cushioning material pad glued and fixed to the top surface inside the packaging box lid.

[0007] Preferably, the main body of the packaging box includes a box body, a J-shaped card plate fixed in the rectangular opening at the upper end of the box body, the box body and the J-shaped card plate are an integral structure, and a U-shaped limiting plate frame located at the four corners inside the box body is glued and fixed, with an opening at the lower corner of the U-shaped limiting plate frame.

[0008] Preferably, the J-shaped card is inserted inside the packaging box lid, with its lower end abutting against the lower end of the inside of the packaging box lid.

[0009] Preferably, the portion of the U-shaped limiting plate frame away from the box body is inserted into the slot on the outside of the buffer material frame, and the U-shaped limiting plate frame is not perpendicular to the inner wall of the box body.

[0010] Preferably, the materials used to form the cushioning material frame and the cushioning material pad can be EPS foam, EPE pearl cotton, or EVA foam.

[0011] The beneficial effects of this utility model are as follows: Through the design of this packaging box, with its double buffer structure, stable connection and limiting design, it achieves efficient protection for the internal items. Furthermore, the structure is reasonable and assembly is convenient. Specific beneficial effects are as follows:

[0012] First, the structure is highly stable. The main body of the packaging box and the lid are tightly locked together by a J-shaped clamp to prevent the lid from falling off; the U-shaped limiting plate frame effectively limits the cushioning material frame to prevent it from shaking. The overall structure fits tightly together, improving the stability of the packaging.

[0013] Secondly, it offers excellent cushioning protection. The cushioning material frame and cushioning pad work together to efficiently absorb impact energy, reduce vibration transmission, and provide reliable protection for the internal items; the non-perpendicular design of the U-shaped limiting plate frame avoids punctures to items, further enhancing protective performance.

[0014] Finally, its overall practicality is outstanding. Each component is rationally designed, with the box serving as the basic carrier, working in conjunction with other components to form a closed space. This not only prevents dust from entering but also allows for easy installation and fixation through a simple structure, balancing protective functions with ease of use. Attached Figure Description

[0024] 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.

[0025] See Figure 1-8 As shown in the figure, a packaging box with a cushioning interlayer in this embodiment includes a packaging box body 1, a packaging box cover 2 is sleeved on the upper end of the packaging box body 1, a cushioning material frame 3 is embedded inside the packaging box body 1, and a cushioning material pad 4 is glued and fixed to the inner top surface of the packaging box cover 2.

[0026] Specifically, the main body 1 of the packaging box serves as the core load-bearing structure of the packaging box. It is a box-shaped structure with an opening at the top, used to accommodate the cushioning material frame 3 and the items to be packaged. It is the basic framework of the entire packaging system, providing support and installation foundation for internal components and items. Its sub-components work together to achieve the functions of fixing the packaging box lid 2 and limiting the position of the cushioning material frame 3.

[0027] The packaging box lid 2 is installed on the upper part of the packaging box body 1 by a socket, and forms a closed packaging space with the packaging box body 1 to protect the internal items and prevent external dust from entering. When the lid is closed, the inside is locked in by the J-shaped card plate 102, and the lower end of the J-shaped card plate 102 abuts against the lower end of its inside, thereby achieving complete fixation between itself and the packaging box body 1.

[0028] See appendix Figure 1-7 As shown, the main body 1 of the packaging box includes a box body 101, a J-shaped card plate 102 fixed in the rectangular opening at the upper end of the box body 101, the box body 101 and the J-shaped card plate 102 are an integral structure, and a U-shaped limiting plate frame 103 located at the four corners inside the box body 101 is glued and fixed. The lower corner of the U-shaped limiting plate frame 103 has an opening.

[0029] The J-shaped card plate 102 is inserted into the inside of the packaging box cover 2, with its lower end abutting against the lower end of the inside of the packaging box cover 2.

[0030] The portion of the U-shaped limiting plate frame 103 away from the box body 101 is inserted into the slot on the outside of the buffer material frame 3, and the U-shaped limiting plate frame 103 is not perpendicular to the inner wall of the box body 101.

[0031] Specifically, the box body 101 is the main part of the packaging box body 1, which has a rectangular box-shaped structure and forms the main outline of the accommodating space. It is used to directly support the J-shaped card plate 102, the U-shaped limiting plate frame 103, as well as the internal cushioning material frame 3 and items, and provides a basic carrier for the installation and support of all internal structures.

[0032] J-shaped card plate 102 is fixed inside the rectangular opening at the upper end of the box body 101. It is an integral structure with the box body 101 and is J-shaped. When the packaging box lid 2 is closed, the J-shaped card plate 102 will be inserted into the inside of the packaging box lid 2. Its lower end abuts against the lower end of the inside of the packaging box lid 2, which helps to realize the socket-type fixation between the packaging box lid 2 and the packaging box body 1, enhances the stability after closing, and prevents the lid from falling off.

[0033] The U-shaped limiting plate frame 103 is glued and fixed to the four corners inside the box body 101. It is U-shaped with an opening at the lower corner and is not perpendicular to the inner wall of the box body 101. The part of it away from the box body 101 is inserted into the slot on the outside of the cushioning material frame 3, which plays a role in positioning and fixing the cushioning material frame 3 and preventing the cushioning material frame 3 from shaking inside the box body 101. Because it is not perpendicular to the inner wall of the box body, it avoids the puncture or damage that vertical structures may cause to the package, and plays a protective role.

[0034] See appendix Figure 1-8 As shown, the materials used to form the cushioning material frame 3 and the cushioning material pad 4 can be EPS foam, EPE pearl cotton, or EVA foam.

[0035] Specifically, the cushioning material frame 3 is embedded inside the main body 1 of the packaging box, and its outer slot will be inserted into the part of the U-shaped limiting plate frame 103 away from the box body 101, so as to achieve its own positioning and fixation. Its main function is to absorb impact energy, reduce vibration transmission, and protect the items placed inside from damage.

[0036] The cushioning material pad 4 is bonded and fixed to the inside top surface of the packaging box lid 2. Together with the cushioning material frame 3, it further absorbs impact energy, reduces vibration transmission, and enhances the protection of the internal products.

[0037] The operation process of this utility model is as follows: When placing the items to be packaged, carefully place the items into the cushioning material frame 3 to ensure that the items are placed stably and in close contact with the cushioning material frame 3, so as to initially protect the items by using the cushioning effect of the cushioning material frame 3.

[0038] When closing the packaging box lid 2, pick up the packaging box lid 2, align it with the upper opening of the packaging box body 1, and slowly slip the packaging box lid 2 onto the upper end of the packaging box body 1. During the closing process, the J-shaped latch 102 at the upper end of the packaging box body 1 will gradually snap into the interior of the packaging box lid 2. Continue to press the packaging box lid 2 down until the lower end of the J-shaped latch 102 abuts against the lower end of the interior of the packaging box lid 2. At this time, the packaging box lid 2 and the packaging box body 1 are completely fixed, forming a closed packaging space. The cushioning material pad 4 will contact the top of the item to be packaged, further enhancing the cushioning protection effect.

[0039] When opening the packaging box, if you need to take out the contents, hold both sides of the packaging box cover 2 and pull upwards to make the J-shaped card plate 102 detach from the inside of the packaging box cover 2, and then remove the packaging box cover 2 from the main body 1 of the packaging box.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
