Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, and in particular to a modular packaging carton. Background Technology

[0002] As an indispensable part of modern goods packaging, cardboard boxes play an important role in protecting products, enhancing their appearance, and facilitating loading. Currently, most existing cardboard boxes require folding and assembling from the cardboard itself, often necessitating the use of tape and staples to secure dust-proof flaps, which is somewhat cumbersome and affects their practicality.

[0003] Therefore, in order to better and faster fix the dustproof flaps of the carton, improve the efficiency of carton assembly, and also for the advancement of industry technology and to enhance core technological competitiveness, this application proposes a new implementation scheme that differs from the existing modular packaging carton structure and application method. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing packaging cartons being unable to quickly fix the dustproof flaps of the cartons and having low assembly efficiency, and to propose a modular packaging carton.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular packaging carton includes a bottom box and a top cover. The bottom box includes a bottom plate, with long side plates on both sides and short side plates on the other two sides. Each of the short side plates has an L-shaped latch at its top end. Each short side plate has a first snap-fit ​​hole on one side. Each of the long side plates has a dustproof flap fixedly connected to both ends, with a slot on one side of each dustproof flap. The latch engages with the slot. The top cover has second snap-fit ​​holes at both ends, and these second snap-fit ​​holes are connected to the first snap-fit ​​holes.

[0007] Furthermore, the long side plates and short side plates are arranged in a staggered ring around the bottom plate.

[0008] Furthermore, the included angles between the long side plate, the short side plate, and the dustproof rocker wing and the base plate are all 90 degrees.

[0009] Furthermore, the included angle between the dustproof wing and the long side plate is 90 degrees.

[0010] Furthermore, each of the dustproof wing has a groove on one side, and the grooves are connected to the first buckle hole and the second buckle hole.

[0011] Furthermore, the bottom two sides of the top cover are fixedly connected with tongues, and the two sides of the tongues are provided with partition grooves.

[0012] Furthermore, both the bottom of the short side plate and the dustproof rocker are provided with insertion holes, and the insertion holes are connected to the insertion tongue.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the design of the latch and slot, can eliminate the traditional methods of assembling and fixing paper boxes, such as tape fixing and stapler fixing, which greatly improves the assembly efficiency of packaging paper boxes, enhances the practicality of packaging cartons, and improves the overall stability when combined with the top cover.

[0015] 2. This utility model provides a first and second buckle hole that are connected through the bottom box and the top cover. During handling, the entire packaging box can be moved simply by inserting both hands into the first and second buckle holes. It has good stability and is easy to assemble.

[0016] 3. By using the tongue and the insertion hole together, this utility model allows the tongue on the top cover to be inserted into the insertion hole on one side of the bottom box after the top cover and bottom box are assembled, thereby further improving the stability of the packaging carton.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-4 A modular packaging carton includes a bottom box and a top cover 5. The bottom box includes a bottom plate 1, which is made of multi-layer honeycomb corrugated cardboard with a thickness of 5-15mm. Long side plates 2 are integrally formed on both sides of the bottom plate 1, and short side plates 3 are integrally formed on the other two sides of the bottom plate 1. The top two ends of the short side plates 3 are integrally formed with latches 301, which are L-shaped. A first snap hole 302 is provided on one side of each short side plate 3. Dustproof flaps 4 are integrally formed on both ends of each long side plate 2, and a slot 401 is provided on one side of each dustproof flap 4. The slot 401 is rectangular. The short L-shaped side of the latch 301 passes through the slot 401, and the long L-shaped side of the latch 301 is snapped onto the dustproof flap 4. The protruding length is 1.3-1.5 times the width of the slot 401. The snap-fit ​​fixing method greatly improves the assembly efficiency of the packaging carton and enhances the practicality of the packaging carton.

[0027] The top cover 5 has second buckle holes 6 at both ends, and the second buckle holes 6 are connected to the first buckle hole 302. When handling, you only need to insert your hands into the first buckle hole 302 and the second buckle hole 6 to handle the entire packaging box. It has good stability and is easy to assemble. The dustproof wing 4 has a groove 402 on one side, and the groove 402 is connected to the first buckle hole 302 and the second buckle hole 6.

[0028] Among them, the long side plate 2 and the short side plate 3 are arranged in a ring around the base plate 1. The included angle between the long side plate 2, the short side plate 3 and the dustproof rocker 4 and the base plate 1 is 90 degrees. The included angle between the dustproof rocker 4 and the long side plate 2 is 90 degrees.

[0029] The working principle of this embodiment is as follows: When in use, firstly, fold the dustproof flaps 4 on both sides of the long side plate 2 along the creases so that the included angle between the dustproof flaps 4 and the long side plate 2 is maintained at 90 degrees. Then, fold the two long side plates 2 and the two short side plates 3 in turn along the creases between them and the bottom plate 1 so that the included angle between the two long side plates 2 and the two short side plates 3 and the bottom plate 1 is maintained at 90 degrees. At this time, the first buckle hole 302 on the short side plate 3 is aligned with the groove 402 on the dustproof flap 4. Next, fold the latch 301 along the creases and engage it with the latch 401. At this time, the bottom box is assembled.

[0030] Next, attach the assembled top cover 5 to the top of the bottom box, so that the first snap hole 302 and the second snap hole 6 are connected.

[0031] When in use, put the items in the bottom box, put the top cover 5 on, and then pack and tie it up. You can move the entire packaging box by simply inserting your hands into the first buckle hole 302 and the second buckle hole 6. It has good stability and is easy to assemble.

[0032] Example 2

[0033] Reference Figures 5-6 A modular packaging carton has tongues 7 integrally formed on both sides of the bottom of the top cover 5, and partition grooves 8 are provided on both sides of the tongues 7. The partition grooves 8 can provide more room for the tongues 7 to move, so as to facilitate insertion. The bottom of the short side plate 3 and the dustproof rocker 4 are provided with insertion holes 9, and the insertion holes 9 are inserted into the tongues 7, thereby further improving the stability of the packaging carton.

[0034] The working principle of the embodiment is as follows: After the assembled top cover 5 and bottom box are assembled, the latch 7 is moved so that the latch 7 is inserted into the insertion hole 9 opened on the short side plate 3 and the dustproof wing 4, which can lock the top cover 5 and bottom box together and prevent them from falling off during transportation.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
