Description

Technical Field

[0001] This application relates to the field of packaging box technology, and in particular to an environmentally friendly one-piece molded packaging box. Background Technology

[0002] Supermarkets face the risk of merchandise theft, especially for small, relatively high-value items like toothpaste. Gluing the lids of toothpaste boxes makes it more difficult for customers to open them directly, thus serving a certain degree of anti-theft purpose. For example, some supermarkets carefully seal the front and back openings of slightly more expensive toothpaste boxes, such as Yunnan Baiyao toothpaste, to prevent customers from simply opening the box and pocketing the toothpaste. Another example is when customers open the toothpaste box and replace the less valuable toothpaste with the more valuable one.

[0003] The following problems exist with packaging boxes glued together: First, traditional adhesives often contain VOCs, which can be released into the air during the bonding process, posing a threat to the environment and human health, such as irritating the respiratory tract and triggering allergic reactions. Second, the production of adhesives not only consumes a large amount of energy, but the wastewater generated during the production process may contain harmful chemicals, which can pollute water bodies if not properly treated. Third, toothpaste boxes glued together are difficult to separate during recycling, increasing the difficulty and cost of recycling. Utility Model Content

[0004] In order to solve the problem of the environmentally unfriendly nature of toothpaste boxes glued together with adhesive as mentioned in the background art, this application provides an environmentally friendly one-piece molded packaging box.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: An environmentally friendly one-piece molded packaging box includes multiple panels formed by die-cutting and folding a single piece of cardboard, and tongues connected to the panels by folds. The multiple panels in the unfolded state are folded along the folds to form a main cavity with openings at both ends. The tongues are used to close the openings at both ends of the main cavity. The two outermost panels in the unfolded state are connected by a snap fastener assembly. In the folded state forming the main cavity, a pair of opposite panels are connected by the tongues and the snap fastener assembly to close the openings of the main cavity.

[0006] By adopting the above technical solution, the main cavity opening is sealed by connecting the two outermost panels with snap fasteners and connecting the two opposing panels with snap fasteners and tongues. This increases the difficulty for customers to directly open the packaging box, thus playing a certain role in preventing theft. It effectively prevents customers from opening the packaging box and putting the toothpaste directly into their pockets, and also prevents customers from opening the packaging box to replace the toothpaste. At the same time, it abandons the traditional glue bonding method, avoiding the harm of volatile organic compounds in traditional glue to the environment and human health. It also reduces energy consumption in the glue production process and the pollution of water bodies by wastewater. In addition, it solves the problem of difficulty in separating glue-bonded packaging boxes during recycling, reducing the difficulty and cost of recycling, and conforming to the concept of environmental protection.

[0007] Optionally, the buckle assembly includes a folded edge with two opposing barbs at the free end and a slot corresponding to the two barbs. The two opposing barbs can deform when subjected to a compressive force in a mutually approaching direction, so that the two opposing barbs pass through the slot and enter the main cavity. The two opposing barbs restore their deformation inside the main cavity when the compressive force is removed. The size of the slot can restrict the two opposing barbs from disengaging in a non-compressive state.

[0008] By adopting the above technical solution, the barbs in the snap fastener assembly can deform and pass through the slot into the main cavity when subjected to the squeezing force in the direction of mutual approach. After the squeezing force is removed, they can restore their deformation. Moreover, the size of the slot can limit the barbs from disengaging in the non-squeezed state, thus ensuring the stability and reliability of the connection between the panels and ensuring that the packaging box can be effectively sealed.

[0009] Optionally, the slot is provided with a serrated line. When the two barbs inside the main cavity are subjected to an external pulling force to disengage from the slot, the serrated line is torn to prevent the two barbs from disengaging from the slot.

[0010] By adopting the above technical solution, a scoring line is set around the slot. When the barb inside the main cavity is subjected to external pulling force to disengage from the slot, the scoring line tears to prevent the barb from disengaging from the slot, which further enhances the anti-theft performance of the packaging box and makes it more difficult for customers to open the packaging without damaging it.

[0011] Optionally, the length of the barb is less than the length of the panel.

[0012] By adopting the above technical solution, the length of the barb is less than the length of the panel. This design ensures that the barb can play its normal connecting role, while avoiding the barb being too long, which would lead to an unreasonable panel structure or affect the overall aesthetics of the packaging box.

[0013] Optionally, the panel without a latch may have a flap connected by a crease, the flap being used to further close the main cavity.

[0014] By adopting the above technical solution, the flip cover can be used to further seal the main cavity, providing an additional sealing method, increasing the sealing of the packaging box, further enhancing the anti-theft effect, and also making the sealing structure of the packaging box more complete.

[0015] Optionally, one of the panels has a plurality of viewing holes evenly distributed on it.

[0016] By adopting the above technical solutions, consumers can easily observe the appearance, color, and other information of toothpaste without opening the packaging box, which improves the product's presentation and appeal and helps consumers make purchasing decisions.

[0017] Optionally, the surface of the barb is provided with anti-slip texture, which is used to prevent the barb from dislodging from the slot when the folded edge with the barb is subjected to an external pulling force away from the slot.

[0018] By adopting the above technical solution, when the panel with barbs is subjected to external pulling force away from the slot, the anti-slip texture can prevent the barbs from disengaging from the slot, further enhancing the connection firmness of the buckle assembly and improving the anti-theft performance and stability of the packaging box.

[0019] Optionally, the edge of the tongue is provided with a rounded transition to facilitate the insertion of the tongue into the main cavity opening for sealing operation.

[0020] The above technical solution features rounded edges on the tongue, facilitating insertion into the main cavity opening for sealing. This makes the assembly and sealing process of the packaging box smoother, improving production efficiency and ease of use.

[0021] The main cavity opening is sealed by connecting the two outermost panels with snap fasteners and connecting the two opposing panels with latches and snap fasteners. This increases the difficulty for customers to directly open the packaging box, thus playing a role in preventing theft to some extent. It effectively prevents customers from opening the packaging box and putting the toothpaste directly into their pockets, and also prevents customers from opening the packaging box to replace the toothpaste. At the same time, it abandons the traditional glue bonding method, avoiding the harm of volatile organic compounds in traditional glue to the environment and human health. It also reduces energy consumption and wastewater pollution in the glue production process, and solves the problem of difficulty in separating glue-bonded packaging boxes during recycling, reducing recycling difficulty and cost, which is in line with the concept of environmental protection.

[0022] The packaging box is formed from a single sheet, eliminating the need for additional splicing or gluing, which significantly reduces material usage and resource consumption. The single-sheet forming process also reduces die-cutting, gluing, and other steps, shortening the production cycle.

[0023] By setting serrations around the slot, when the barb inside the main cavity is subjected to external pulling force to disengage from the slot, the serrations tear to prevent the barb from disengaging from the slot, further enhancing the anti-theft performance of the packaging box. This makes it more difficult for customers to open the packaging without damaging it, and makes it easier for cashiers to observe whether the toothpaste box is damaged or whether the toothpaste inside has been replaced during checkout.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] For existing paper-molded packaging boxes, the main components include multiple panels 2 formed by die-cutting and folding a single piece of cardboard 1, and tongues 4 connected to the panels 2 by folds 3. The multiple panels 2 in the unfolded state are folded along the folds 3 to form a main cavity 5 with openings at both ends. The tongues 4 are used to close the openings at both ends of the main cavity 5. When in use, toothpaste is placed into the main cavity 5 through one opening, and then the tongues 4 are glued to the panels 2 to close the main cavity 5 and ensure the integrity of the entire packaging box.

[0028] This application discloses an environmentally friendly one-piece molded packaging box, see reference. Figures 1 to 6Based on existing technology, the two outermost panels 2 of the multiple panels 2 in the unfolded state are connected by a snap-fit ​​assembly. In the folded state forming the main cavity 5, a pair of opposing panels 2 are connected by a tongue 4 and a snap-fit ​​assembly to close the opening of the main cavity 5. The snap-fit ​​assembly includes a folded edge 7 with two opposing barbs 6 at their free ends and a slot 8 corresponding to the two barbs 6. The two opposing barbs 6 can deform when subjected to pressure in a mutually approaching direction, allowing them to pass through the slot 8 and enter the main cavity 5. When the pressure on the two opposing barbs 6 is removed... The deformation is restored inside the main cavity 5, and the size of the slot 8 can limit the two opposing barbs 6 from disengaging in a non-compressed state. The length of the barb 6 is less than the length of the folded edge 7 (the length of the folded edge 7 is the same as the length of the panel 2), which ensures that the barbs 6 can play a normal connecting role, while avoiding the barbs 6 being too long, which would cause unreasonable structure of the panel 2 or affect the overall aesthetics of the packaging box. At the same time, anti-slip texture is provided on the surface of the barbs 6. When the panel 2 with barbs 6 is subjected to external pulling force away from the slot 8, the anti-slip texture can prevent the barbs 6 from disengaging from the slot 8, further enhancing the connection firmness of the buckle assembly. In order to facilitate the understanding of this technical solution by those skilled in the art, such as Figure 6The packaging box shown consists of four panels 2, named from right to left as first panel 19, second panel 20, third panel 21, and fourth panel 22. At the end of the fourth panel 22 furthest from the third panel 21, a first folded edge 13 with two opposing first barbs 14 is connected via a crease 3. A first slot 15, adapted to fit the first barbs 14, is formed on the first panel 19. When multiple panels 2 are folded sequentially to form the main cavity 5, the first folded edge 13 wraps around the edge of the first panel 19 and approaches the first slot 15, applying a pressing force to the two first barbs 14, causing them to approach and fit together, allowing the first barbs 14 to pass through the first slot 15. Once inside the main cavity 5, the two first barbs 14 extending into the main cavity 5 lose their compressive force and recover their deformation. At this time, the two first barbs 14 are perpendicular to the first folded edge 13, limiting the first folded edge 13 and connecting the first panel 19 and the fourth panel 22 together. When the first folded edge 13 passes around the first panel 19, the first folded edge 13 fits tightly against the surface of the first panel 19. When the first barb 14 passes through the first slot 15 and is inserted into the main cavity 5, the distance from the upper surface of the first barb 14 to the inner wall of the first folded edge 13 is exactly the thickness of the first panel 19, so as to prevent the first folded edge 13 from extending excessively into the main cavity 5 and affecting the stability of the entire packaging box. Furthermore, a tongue 4 with a second folded edge 16 is provided at both ends of the first panel 19. The free ends of the second folded edge 16 are two opposing second barbs 17. Two second slots 18, adapted to the second barbs 17, are symmetrically opened on the third panel 21. (Alternatively, a tongue 4 with a second folded edge 16 can be provided at both ends of the second panel 20, and two second slots 18 adapted to the second barbs 17 can be symmetrically opened on the fourth panel 22.) First, the second folded edge 16 at one end of the first panel 19 is wrapped around and pressed tightly against the third panel 21. Simultaneously, a pressing force is applied to the second barbs 17 at both ends of the second folded edge 16, causing the two second barbs 17 to deform and move closer together, allowing them to pass through the second slots 18 and extend into the main cavity 5. The two second barbs 17 extending into the main cavity 5 lose their... When the extrusion pressure recovers the deformation, the two second barbs 17 are perpendicular to the second folded edge 16, limiting the second folded edge 16 and connecting the tongue 4 to the third panel 21, thus closing one end of the packaging box opening. The toothpaste is then placed into the main cavity 5, and the above steps are repeated to close the other opening. In practical applications, rounded corners can be provided on the edge of the tongue 4 to facilitate insertion of the tongue 4 into the main cavity 5 opening for closing, making the assembly and closing process of the packaging box smoother. To further enhance the sealing effect, a flap 11 is connected to the panel 2 without the tongue 4 via a crease 3. When multiple panels 2 are folded to form the main cavity 5, two flaps 11 are symmetrically arranged on both sides of one tongue 4. Figure 6As shown, when the first panel 19 has tongues 4 at both ends, the second panel 20 and the fourth panel 22 both have flaps 11 at both ends. In the above steps, the flaps 11 are first placed over the opening of the main cavity 5, and then the tongues 4 are fixed to the panel 2, providing a relatively closed cavity for the toothpaste. This provides a certain degree of anti-theft protection, effectively preventing customers from opening the packaging box and putting the toothpaste directly into their pockets, and also preventing customers from opening the packaging box to replace the toothpaste. At the same time, it eliminates the need for traditional glue bonding, avoiding the harm of volatile organic compounds (VOCs) in traditional glues to the environment and human health, and also reducing energy consumption in the glue production process. This method also addresses the pollution of water bodies by wastewater, while simultaneously solving the problem of separating glued packaging boxes during recycling. This reduces the difficulty and cost of recycling, aligning with environmental protection principles. To prevent the stability of the packaging box from being affected during transportation, the panel 2, hooks 6, and folded edges 7 can be made of cardboard 1, such as white cardboard, which has a certain degree of rigidity, making it easier to maintain the shape of the packaging box. At the same time, the hooks 6 are not easy to detach from the slots 8 without external force, and are recyclable and biodegradable, in line with environmental protection trends. This packaging box is formed from a single sheet, without the need for additional splicing or gluing, significantly reducing material usage and resource consumption. The single-sheet forming process reduces die-cutting, gluing, and other steps, shortening the production cycle.

[0029] Further reference Figure 6 To further enhance the anti-theft performance of the packaging box, a serrated line 9 is set around the slot 8. The area enclosed by the serrated line 9 forms an easy-tear zone 10. When the barb 6 inside the main cavity 5 is subjected to external pulling force to disengage from the slot 8, the serrated line 9 tears to prevent the barb 6 from disengaging from the slot 8, making it more difficult for customers to open the packaging box without damaging it. When a customer tries to tear open the packaging box to steal or replace the toothpaste, it can attract the attention of those around them. At the checkout counter, it is convenient for the cashier to check whether the toothpaste purchased by the customer matches the packaging box. To meet the customer's need to check the toothpaste before purchasing, multiple viewing holes 12 are made on the toothpaste box, such as... Figure 4 and Figure 6 As shown, there are three viewing holes 12, and the viewing holes 12 are opened on the first panel 19, that is, on the top surface of the packaging box when it is upright. The number and size of the viewing holes 12 are sufficient for customers to see the general shape of the toothpaste. In order to maintain the stability of the packaging box and prevent dust or impurities from entering the main cavity 5, it is not advisable to open too many viewing holes 12 or too large a size.
