Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically a reinforced packaging carton. Background Technology

[0002] Cardboard boxes are packaging materials used to protect products, facilitate storage and transportation, and promote sales during the distribution process. They are the most widely used packaging method, typically used as wrapping materials for goods or as protective outer layers for items.

[0003] Currently, cardboard boxes are commonly used. Existing cardboard boxes are usually designed with openings at the top and bottom, with lids at the top and bottom, and sealed with tape. However, in actual use, these cardboard boxes have poor load-bearing capacity. When the contents of the box are heavy, the bottom lid seal is easily torn open. Furthermore, the bottom lid seal is frequently in contact with other items and is very susceptible to wear and tear, causing the tape seal to break and the contents of the box to fall out. Therefore, we have proposed a reinforced cardboard box to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforced packaging carton to solve the problem of poor stress resistance of packaging cartons currently on the market, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced packaging carton, comprising a carton body, with a main carton lid on both the upper and lower sides of the carton body; a reinforcing cardboard is adhered to the inner wall of the carton body on the side corresponding to the main carton lid; an inner lining side panel is connected to the inner side of the carton body; an inner lining board is provided on the lower side of the inner lining side panel; an inner lining lid is provided on the upper side of the inner lining side panel; the inner lining lid, inner lining board, and inner lining side panel are integrally formed; the inner lining lid, inner lining board, and inner lining side panel form a "U"-shaped structure within the carton body; and handle openings are provided on both the inner lining side panel and the carton body, with a reinforcing handle installed in the handle opening.

[0006] Preferably, the reinforcing cardboard is connected to inner lining side panels on both the left and right sides, and the distance between the reinforcing cardboard and the left and right sides of the main body of the carton and the left and right sides of the main body of the carton is equal to the thickness of the inner lining side panels.

[0007] Preferably, the inner side surfaces of the inner liner cover and the inner liner plate are attached with female Velcro, and the outer side surface of the main body cover is attached with female Velcro. When the main body cover is closed, the inner liner cover and the inner liner plate are both located on the outer side of the main body cover and are fixedly connected by the female Velcro and the female Velcro.

[0008] Preferably, the reinforced handle is fixed with a connecting edge and a snap-fit ​​block, and the external dimensions of the connecting edge and the snap-fit ​​block are the same as the handle opening dimensions on the inner lining side panel and the carton body.

[0009] Preferably, an inner fixing pad is sleeved on the outer side of the connecting edge and the snap-fit ​​block, and the inner fixing pad is fixed by the snap-fit ​​block for limiting and snapping.

[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] Please see Figures 1-7 This utility model provides a technical solution: a reinforced packaging carton, including a carton body 1, with a main carton cover 2 on both the upper and lower sides of the carton body 1, and a reinforcing cardboard 3 glued to the inner wall of the carton body 1 on the side corresponding to the main carton cover 2.

[0026] Furthermore, the reinforcing cardboard 3 is connected to the inner side panels 9 on both the left and right sides. The distance between the reinforcing cardboard 3 and the left and right sides of the main body 1 and the left and right sides of the main body 1 is equal to the thickness of the inner side panels 9. This ensures that the inner side panels 9 are limited inside the main body 1, thereby achieving a stable state and ensuring that the opening and closing of the main body 1 is not affected.

[0027] The inner side of the carton body 1 is connected to an inner lining side plate 9. An inner lining bottom plate 8 is provided on the lower side of the inner lining side plate 9, and an inner lining box cover 6 is provided on the upper side of the inner lining side plate 9. The inner lining box cover 6, the inner lining bottom plate 8 and the inner lining side plate 9 are integrated and form a "U" shaped structure inside the carton body 1.

[0028] Furthermore, female hook and loop fasteners 7 are attached to the inner sides of the inner liner cover 6 and the inner liner plate 8, and male hook and loop fasteners 14 are attached to the outer side of the main body cover 2. When the main body cover 2 is closed, the inner liner cover 6 and the inner liner plate 8 are located on the outer side of the main body cover 2 and are fixedly connected by the female hook and loop fasteners 7 and the male hook and loop fasteners 14. This not only strengthens the connection between the inner liner cover 6 and the inner liner plate 8 and the main body cover 2, but also facilitates disassembly and assembly, thereby improving the performance of the packaging carton.

[0029] Both the inner side panel 9 and the main body of the carton 1 have handle openings 10, and a reinforced handle 4 is installed inside the handle openings 10.

[0030] Furthermore, the reinforcing handle 4 is fixed with a connecting edge 12 and a snap-fit ​​block 13. The external dimensions of the connecting edge 12 and the snap-fit ​​block 13 are the same as the dimensions of the handle opening 10 on the inner lining side plate 9 and the carton body 1, ensuring that the connecting edge 12 and the snap-fit ​​block 13 of the reinforcing handle 4 are stably inserted into the inner lining side plate 9 and the carton body 1, thereby achieving a stable connection between the inner lining side plate 9 and the carton body 1.

[0031] Furthermore, an inner fixing pad 5 is sleeved on the outer side of the connecting edge 12 and the snap-fit ​​block 13. The inner fixing pad 5 is fixed by the snap-fit ​​block 13. The reinforcing handle 4 is located on the outer side of the carton body 1, and the inner fixing pad 5 is located on the inner side of the inner lining side plate 9. The inner fixing pad 5 is fixed by the snap-fit ​​block 13 to achieve the clamping and fixing of the reinforcing handle 4 and the inner fixing pad 5 on the inner lining side plate 9 and the carton body 1.

[0032] Furthermore, a reinforcing pad 11 is attached and fixed around the handle opening 10 on the inner side panel 9 to enhance the stress resistance at the handle opening 10 on the inner side panel 9, thereby preventing tearing at the handle opening 10 when handling the packaging carton and ensuring the safe use of the packaging carton.

[0033] Specifically, when using this reinforced packaging carton, first assemble the inner liner cover 6, inner liner plate 8 and inner liner side plate 9 into the carton body 1, and insert the inner liner cover 6 and inner liner side plate 9 from the bottom of the carton body 1.

[0034] The inner lining lid 6 protrudes from the upper part of the carton body 1 and is positioned opposite to the main body lid 2 at the upper part of the carton body 1. The inner lining side panel 9 is located inside the carton body 1 and is limited by the reinforcing cardboard 3 to ensure that the inner lining side panel 9 is stably attached to the inner wall of the carton body 1.

[0035] The inner lining board 8 is located at the bottom of the carton body 1, and the main box cover 2 at the bottom of the carton body 1 is in a closed state. The inner lining board 8 is located on the outside of the main box cover 2. In this state, the inner lining board 8 and the main box cover 2 are connected and fixed by the female hook and loop fastener 7 and the female hook and loop fastener 14 to ensure that the inner lining board 8 and the main box cover 2 are in a stable working state.

[0036] Then, the connecting edge 12 and the snap-fit ​​block 13 on the reinforcing handle 4 are passed through the handle opening 10 on the carton body 1 and the inner lining side panel 9, and the inner fixing pad 5 is connected to the connecting edge 12 and the snap-fit ​​block 13 from the inside. In this way, the carton body 1 and the inner lining side panel 9 can be clamped and fixed by the reinforcing handle 4 and the inner fixing pad 5.

[0037] After assembling the packaging carton, place the items directly into the main body 1 of the carton. The reinforcing cardboard 3, the inner side panel 9, and the bottom main body lid 2 are in direct contact with the items to ensure safe placement. Then, close the upper main body lid 2, and then close the inner liner lid 6. The inner liner lid 6 and the main body lid 2 are connected and fixed by the female hook and loop fastener 7 and the male hook and loop fastener 14 to ensure the stability of the inner liner lid 6 and the main body lid 2. Finally, seal the inner liner lid 6 with tape to complete the item placement in the packaging carton.

[0038] When handling the packaging carton, the handle 4 is reinforced to ensure that the handle opening 10 is evenly stressed, thus preventing tearing at the handle opening 10. At the same time, the handle opening 10 on the inner lining side plate 9 is also equipped with a reinforcing pad 11 to further enhance the stress performance of the handle opening 10. During handling, the weight of the contents inside the carton presses on the main carton cover 2 below. Under the action of the inner lining side plate 8, the inner lining side plate 9, and the inner lining carton cover 6, the stress strength of the carton is enhanced, ensuring the safe use of the carton.

[0039] When retrieving items later, the inner liner box 6 and the main body box 2 can be opened directly to retrieve the items. The packaging box can be reused for a long time, thus increasing its value.

[0040] The above describes the usage process of this packaging carton. Any content not described in detail in this manual is existing technology known to those skilled in the art.
