Description

Technical Field

[0001] This utility model relates to the field of cardboard packaging technology, specifically a cardboard box joining structure. Background Technology

[0002] In the packaging industry, cardboard boxes are a widely used logistics transportation and storage medium, and the design of their sealing structure directly affects the safety, stability, and production efficiency of the packaging. Traditional cardboard box sealing methods usually rely on tape or a single adhesive for sealing, such as using transparent tape or hot melt adhesive to seal and fix the top and bottom of the cardboard box.

[0003] However, in warehousing or transportation, cartons are often stacked vertically. Existing sealing designs only focus on the sealing function of a single carton, lacking an effective connection mechanism, which makes it easy for cartons to wobble when stacked, increasing the risk of goods collapsing. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a carton joining structure. This solves the problem that existing sealing designs only focus on the sealing function of a single carton and lack an effective connection mechanism, which makes it easy for the cartons to shake when stacked, increasing the risk of goods collapsing.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a carton joining structure, comprising:

[0006] Cardboard box;

[0007] The first sticker is placed on the top seal of the carton;

[0008] The second sticker is placed on the bottom seal of the carton;

[0009] An adhesive, which is applied to one side of the first sticker and the second sticker;

[0010] Multiple first reinforcing ribs are distributed sequentially and at intervals along the side length of the first sticker on the first sticker;

[0011] Multiple second reinforcing ribs are distributed sequentially and at intervals along the side length of the second sticker on the second sticker;

[0012] The slot is formed inside each of the second reinforcing ribs, and the first reinforcing rib slides within the slot of the second reinforcing rib.

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

[0014] 1) First and second stickers are coated with adhesive and pasted onto the top and bottom seals of the carton to form a preliminary seal. On this basis, multiple first and second reinforcing ribs are set on the first and second stickers respectively, forming a dual mechanism of "chemical bonding (adhesive) combined with physical structure (reinforcing ribs)". Compared with traditional single tape sealing, it not only significantly improves the tensile strength and tear resistance of the seal, but also effectively resists external forces such as squeezing and vibration during transportation, ensuring the safety of the contents of the carton. At the same time, the slotted interlocking structure of the first and second reinforcing ribs can serve as a connection and limiting mechanism between adjacent cartons. When multiple cartons are stacked, the first reinforcing rib of the lower carton can slide into the slot of the second reinforcing rib of the upper carton to form a stable interlocking connection, effectively preventing the cartons from shaking during stacking, significantly improving the stability of the overall stacking structure, and eliminating the need for subsequent tape reinforcement in traditional sealing.

[0015] 2) In summary, by bonding and fixing the first sticker and the second sticker, and by interlocking the reinforcing ribs and the card slots, the problem of insufficient sealing strength and poor stacking stability of traditional cardboard boxes is cleverly solved. It is suitable for ordinary logistics packaging, as well as transportation scenarios with high-strength protection or frequent stacking, and has broad application prospects and practical value.

[0016] Based on the above technical solution, the present invention can be further improved as follows.

[0017] Furthermore, the adhesive is a double-sided adhesive.

[0018] Furthermore, both the first reinforcing rib and the slot have cross-sections that are wider at the top and narrower at the bottom, forming an isosceles trapezoid.

[0019] The beneficial effect of adopting the above-mentioned further solution is that after the first reinforcing rib slides into the slot and is fitted, due to its narrower lower part, the first reinforcing rib and the slot form a tight fit, which can prevent the first reinforcing rib from coming loose from the slot, thereby enhancing the limiting connection strength between the two cartons and ensuring the overall stability of the stacking structure.

[0020] Furthermore, both the first and second stickers are made of kraft paper.

[0021] Furthermore, both the first and second reinforcing ribs are made of plastic. Attached Figure Description

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] In the packaging industry, cardboard boxes are a widely used logistics transportation and storage medium, and the design of their sealing structure directly affects the safety, stability, and production efficiency of the packaging. Traditional cardboard box sealing methods usually rely on tape or a single adhesive for sealing, such as using transparent tape or hot melt adhesive to seal and fix the top and bottom of the cardboard box.

[0032] However, in warehousing or transportation, cartons are usually stacked vertically. Existing sealing designs only focus on the sealing function of a single carton and lack an effective connection mechanism, which makes it easy for cartons to wobble when stacked, increasing the risk of goods collapsing. To address this problem, the inventor has proposed a carton joining structure.

[0033] The present invention provides the following preferred embodiments.

[0034] like Figures 1-6 As shown, a carton joining structure includes:

[0035] 100 cardboard boxes;

[0036] The first sticker 200 is placed on the top seal of the carton 100;

[0037] The second sticker 300 is placed on the bottom seal of the carton 100;

[0038] Adhesive 400 is applied to one side of the first sticker 200 and the second sticker 300;

[0039] Multiple first reinforcing ribs 500 are distributed sequentially and at intervals along the side length of the first sticker 200 on the first sticker 200.

[0040] Multiple second reinforcing ribs 600 are distributed sequentially and at intervals along the side length of the second sticker 300 on the second sticker 300.

[0041] The slot 700 is formed inside each of the second reinforcing ribs 600, and the first reinforcing rib 500 slides within the slot 700 of the second reinforcing rib 600;

[0042] First sticker 200 and second sticker 300 are coated with adhesive 400 and affixed to the top and bottom seals of carton 100 to form a preliminary seal. Furthermore, multiple first reinforcing ribs 500 and multiple second reinforcing ribs 600 are respectively placed on the first sticker 200 and the second sticker 300, forming a dual mechanism of "chemical bonding (adhesive 400) combined with physical structure (reinforcing ribs)". Compared to traditional single-tape sealing, this significantly improves the tensile strength and tear resistance at the seal, and effectively resists compression and vibration during transportation. External force ensures the safety of the items inside the carton 100. At the same time, the interlocking structure of the slots 700 of the first reinforcing rib 500 and the second reinforcing rib 600 can serve as a connection and limiting mechanism between adjacent carton 100. When multiple carton 100 are stacked, the first reinforcing rib 500 of the lower carton 100 can slide into the slot 700 of the second reinforcing rib 600 of the upper carton 100 to form a stable interlocking connection. This effectively prevents the carton 100 from shaking during the stacking process, significantly improves the stability of the overall stacking structure, and eliminates the need for subsequent reinforcement with tape in traditional sealing methods.

[0043] In summary, by bonding and fixing the first sticker 200 and the second sticker 300, and by interlocking and connecting the reinforcing rib and the card slot 700, the problem of insufficient sealing strength and poor stacking stability of traditional cardboard boxes 100 is cleverly solved. It is suitable for ordinary logistics packaging, as well as transportation scenarios requiring high-strength protection or frequent stacking, and has broad application prospects and practical value.

[0044] In this embodiment, as Figures 1-6 As shown, adhesive 400 is a double-sided adhesive.

[0045] In this embodiment, as Figures 1-6As shown, the cross-sections of the first reinforcing rib 500 and the slot 700 are both isosceles trapezoids that are wider at the top and narrower at the bottom. After the first reinforcing rib 500 slides into the slot 700 and is fitted together, due to its narrower lower part, the first reinforcing rib 500 and the slot 700 form a tight fit, which can prevent the first reinforcing rib 500 from coming loose from the slot 700, thereby enhancing the limiting connection strength between the two cartons 100 and ensuring the overall stability of the stacking structure.

[0046] In this embodiment, as Figures 1-6 As shown, both the first sticker 200 and the second sticker 300 are made of kraft paper. The stickers made of kraft paper have a simple and elegant appearance, which can add an environmentally friendly and high-end feel to the cardboard box 100. They also have high hardness and tear resistance.

[0047] In this embodiment, as Figures 1-6 As shown, both the first reinforcing rib 500 and the second reinforcing rib 600 are made of plastic.

[0048] The specific working process of this utility model is as follows:

[0049] First, double-sided adhesive is applied to the first sticker 200 and the second sticker 300 respectively. Then, the first sticker 200 and the second sticker 300 with double-sided adhesive are respectively attached to the top and bottom seals of the carton 100 to form a closure of the carton 100. On this basis, multiple first reinforcing ribs 500 and multiple second reinforcing ribs 600 are respectively provided on the first sticker 200 and the second sticker 300. The interlocking structure of the slots 700 of the first reinforcing ribs 500 and the second reinforcing ribs 600 can serve as a connection and limiting mechanism between adjacent carton 100s. When multiple carton 100s are stacked, the first reinforcing rib 500 of the lower carton 100 can slide into the slots 700 of the second reinforcing ribs 600 of the upper carton 100 to form a stable interlocking connection.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
