Description

Technical Field

[0001] This utility model belongs to the field of packaging carton technology, and particularly relates to a carton with a built-in adhesive mechanism. Background Technology

[0002] With the rapid development of e-commerce logistics, traditional ordinary packaging cartons rely on additional tape for sealing, which involves cumbersome procedures, waste of materials, and low efficiency, and is gradually unable to meet the needs of e-commerce for convenient and cost-effective delivery.

[0003] To address this pain point, cardboard boxes with built-in adhesive mechanisms have emerged—by integrating a single-use adhesive strip and an easy-tear strip along the sealing edge, a closed loop is created for convenient sealing by the merchant (adhesive strip) and convenient unpacking by the customer (easy-tear strip). However, these cardboard boxes have functional limitations: when customers return the goods, the original adhesive strip is damaged, requiring additional tape for resealing, reverting to the original problem of "consumable dependence" and leaving the hassle to the customer.

[0004] To overcome the limitations of single-use, some cardboard boxes have been designed with a two-stage sealing-opening structure. This involves a multi-layered layout along the sealing edge, consisting of "adhesive strip 1 → easy-tear strip 2 → adhesive strip 3 → easy-tear strip 4," attempting to cover the entire process of "shipping sealing → receiving unpacking → returning sealing → secondary unpacking." However, this design has flaws in practical use. Because the structure does not enforce a strict order of operations, confusion can easily occur. If the user applies the inner adhesive strip 3 first, the outer adhesive strip 1 becomes ineffective because it is not triggered. If the inner easy-tear strip 4 is accidentally torn, the secondary sealing function of adhesive strip 3 is rendered useless. Ultimately, the two functions cannot be seamlessly connected. Either the initial sealing wastes the inner layer structure, or the secondary sealing fails prematurely due to misoperation, failing to achieve true reusability without additional consumables.

[0005] In summary, while existing technologies have solved the convenience of single-time sealing and opening, there is a gap in the forced sequential control of the two functions. Designers need to develop a carton that ensures that the adhesive strip and the easy-tear strip are activated strictly in sequence to avoid premature misoperation. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this utility model is to provide a cardboard box with a built-in adhesive mechanism, which ensures that the double adhesive strips and double easy-tear strips are activated strictly and sequentially, and avoids premature misoperation.

[0007] The technical solution of this utility model is as follows:

[0008] A cardboard box with a built-in adhesive mechanism includes a bottom plate, side plates connected to the top and bottom ends of the bottom plate, a front panel connected to the left side of the bottom plate, a rear panel connected to the right side of the bottom plate, a top plate connected to the side of the rear panel away from the bottom plate, and a first adhesive plate and a second adhesive plate connected sequentially to the side of the top plate away from the rear panel, each having an adhesive mechanism.

[0009] The adhesive mechanism includes a first easy-tear strip and a second easy-tear strip spaced apart on the first adhesive plate. The first easy-tear strip is close to the second adhesive plate, and the second easy-tear strip is close to the top plate. The first adhesive strip is provided on the upper surface of the second adhesive plate, and the second adhesive strip is provided on the lower surface of the first adhesive plate. Both the first and second adhesive strips are disposable pressure-sensitive adhesive strips, initially covered with release paper.

[0010] In use, the second adhesive plate is bent inward, with its upper surface adhering to the front panel and its lower surface adhering to the lower surface of the first adhesive plate.

[0011] Furthermore, at least one horizontal slot is provided at the connection between the bottom plate and the side plate. The side plate is connected to a first flap at the end away from the bottom plate. The free end of the first flap is provided with a tooth that mates with the slot. During assembly, the side plate is bent to be perpendicular to the bottom plate, and then the first flap is bent inward so that the tooth and the slot are precisely engaged. The mechanical engagement structure enhances the connection stability between the side plate and the bottom plate, prevents the side plate from expanding outward when the carton is under load, and ensures that the overall structure maintains its shape integrity during multiple sealing and unsealing processes.

[0012] Furthermore, the front panel and the rear panel are connected to the top and bottom ends of the second and third flaps, respectively, and neither the second nor the third flap is connected to the side panel.

[0013] Furthermore, the second adhesive strip is located between the first and second easy-tear strips. The positional separation ensures that the second adhesive strip does not overlap with the easy-tear strip, avoiding damage to the adhesive strip when the easy-tear strip is removed, and ensuring the reliability of the secondary sealing.

[0014] Furthermore, the first easy-tear strip has a first handle on each side of the first adhesive board, and multiple through slots are arranged in two parallel rows between the two handles, extending along the width of the first adhesive board to form a complete easy-tear strip; the second easy-tear strip has a second handle on each side of the first adhesive board, and a set of through slots is provided in the area near each handle, with a solid connection between the two sets of through slots. Each set of through slots includes two through slots arranged in parallel. The two handles of the first easy-tear strip have a complete easy-tear strip structure, ensuring that the second adhesive strip will not be damaged when the box is opened for the first time. The solid connection between the two handles of the second easy-tear strip increases the strength of this part and prevents the structure of the second easy-tear strip from being damaged when the box is opened for the first time.

[0015] Furthermore, the second adhesive plate has a movable tongue that mates with the second handle. One side of the movable tongue is connected to the second adhesive plate, and the movable tongue folds in one direction around the connecting edge, with the folding direction always facing the second handle. In use, the edge of the free end of the second handle is respectively engaged between the movable tongue and the front panel. Through the engagement and disengagement mechanism of the movable tongue and the second handle, a mechanical interlock is formed from the initial covering to the exposure after unpacking, forcing the user to operate in the order of first tear strip followed by second tear strip, thus structurally eliminating the risk of misoperation.

[0016] Furthermore, a guide notch is provided between the front side of the movable tongue away from the connecting edge and the second adhesive plate. The guide notch guides the handle to be inserted, reducing the difficulty of alignment operation when sealing the box and improving the smoothness of operation.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model integrates double adhesive strips and double easy-tear strips, which can complete the entire process of "first sealing - unpacking - second sealing - second unpacking" without additional tape, thus solving the problem of traditional cardboard box second sealing relying on consumables.

[0019] 2. This utility model guides users to operate in the order of "first adhesive strip → first easy-tear strip → second adhesive strip → second easy-tear strip" by using a movable tongue cover and a folding adhesive plate, thus preventing premature misuse of the secondary structure.

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

[0027] like Figures 1 to 5 As shown, a cardboard box with a built-in adhesive mechanism includes a bottom plate 1, side plates 2 connected to the top and bottom ends of the bottom plate 1, a front panel 3 connected to the left side of the bottom plate 1, a rear panel 4 connected to the right side of the bottom plate 1, a top plate 5 connected to the side of the rear panel 4 away from the bottom plate 1, and a first adhesive plate 6 and a second adhesive plate 7 connected sequentially to the side of the top plate 5 away from the rear panel 4, both of which are provided with adhesive mechanisms.

[0028] The adhesive mechanism includes a first easy-tear strip 6-1 and a second easy-tear strip 6-2 spaced apart on the first adhesive plate 6. The first easy-tear strip 6-1 is close to the second adhesive plate 7, and the second easy-tear strip 6-2 is close to the top plate 5. The first adhesive strip 7-1 is provided on the upper surface of the second adhesive plate 7, and the second adhesive strip 6-3 is provided on the lower surface of the first adhesive plate 6. Both the first adhesive strip 7-1 and the second adhesive strip 6-3 are disposable pressure-sensitive adhesive strips, initially covering release paper. The edges of the release paper are provided with tabs for easy peeling.

[0029] In use, the second adhesive plate 7 is bent inward, with its upper surface adhering to the front panel 3 and its lower surface adhering to the lower surface of the first adhesive plate 6.

[0030] Furthermore, at least one slot 9 is horizontally provided at the connection between the bottom plate 1 and the side plate 2. The end of the side plate 2 away from the bottom plate 1 is connected to a first flap 8. The free end of the first flap 8 is provided with a tooth that mates with the slot 9. During assembly, the side plate 2 is bent to be perpendicular to the bottom plate 1, and then the first flap 8 is bent inward so that the tooth and the slot 9 are precisely engaged. The mechanical engagement structure enhances the connection stability between the side plate 2 and the bottom plate 1, prevents the side plate 2 from expanding outward when the carton is under load, and ensures that the overall structure maintains its shape integrity during multiple sealing and unsealing processes.

[0031] Furthermore, the front panel 3 and the rear panel 4 are respectively connected to the upper and lower ends of the second fold 10 and the third fold 11. The second fold 10 and the third fold 11 are not connected to the side panel 2. Before sealing the carton, the second fold 10 and the third fold 11 are bent inward, and their edges are attached to the inner wall of the side panel 2 to form a closed cover on the end of the carton.

[0032] Furthermore, the second adhesive strip 6-3 is located between the first easy-tear strip 6-1 and the second easy-tear strip 6-2. The positional separation ensures that the second adhesive strip 6-3 does not overlap with the easy-tear strip, avoiding damage to the adhesive strip when tearing off the easy-tear strip and ensuring the reliability of the secondary sealing.

[0033] Furthermore, the first easy-tear strip 6-1 is provided with first handles 6-1.1 on both sides of the first adhesive plate 6. Between the two handles, multiple through slots are arranged in two parallel rows, extending along the width of the first adhesive plate 6 to form a complete easy-tear strip. The second easy-tear strip 6-2 is provided with second handles 6-2.1 on both sides of the first adhesive plate 6. A set of through slots is provided in the area near the two handles. There is a solid connection between the two sets of through slots. Each set of through slots includes two through slots arranged in parallel. The two handles of the first easy-tear strip 6-1 are provided with a complete easy-tear strip structure to ensure that the second adhesive strip 6-3 will not be damaged when the box is opened for the first time. The two handles of the second easy-tear strip 6-2 are provided with a solid connection, which increases the strength of this part and avoids damage to the structure of the second easy-tear strip 6-2 when the box is opened for the first time.

[0034] Furthermore, the second adhesive plate 7 has a movable tongue 7-2 that mates with the second handle 6-2.1. One side of the movable tongue 7-2 is connected to the second adhesive plate 7. The movable tongue 7-2 is folded in one direction around the connecting edge, with the folding direction facing the second handle 6-2.1. In use, the edge segments of the free end of the second handle 6-2.1 are respectively inserted between the movable tongue 7-2 and the front panel 3. Through the engagement and disengagement mechanism of the movable tongue 7-2 and the second handle 6-2.1, a mechanical interlock is formed from the initial covering to the exposure after unpacking, forcing the user to operate in the order of first tear strip 6-1 and then second tear strip 6-2, thus eliminating the risk of misoperation from a structural perspective.

[0035] Furthermore, a guide notch 7-3 is provided between the front side of the movable tongue 7-2 away from the connecting edge and the second adhesive plate 7. The guide notch 7-3 guides the handle to be inserted, reducing the difficulty of alignment operation when sealing the box and improving the smoothness of operation.

[0036] Principle Explanation: During the initial sealing of the box, the second adhesive plate 7 is bent inward. Then, the second handle 6-2.1 of the second easy-tear strip 6-2 is inserted into the lower end of the movable tongue 7-2 through the guide notch 7-3. The movable tongue 7-2 covers the second handle 6-2.1 of the second easy-tear strip 6-2, leaving only the first adhesive strip 7-1 exposed. The user can only peel off the release paper of the first adhesive strip 7-1. The first adhesive strip 7-1 and the front panel... 3. Adhesion: During the initial unpacking, because the second handle 6-2.1 is covered, the user can only choose to tear off the first easy-tear strip 6-1 through the first handle 6-1.1. The second adhesive plate 7 will remain on the front panel 3. The second handle 6-2.1 is pulled out from the movable tongue 7-2 to complete the exposure. During the second sealing, peel off the release paper of the second adhesive strip 6-3 and stick the first adhesive plate 6 onto the second adhesive plate 7. During the second unpacking, tear off the second easy-tear strip 6-2.
