Description

Technical Field

[0001] This invention relates to the field of packaging, and in particular to a method for manufacturing a carrying box that is easy to fold and transport. Background Technology

[0002] Most beverage packaging boxes on the market only have gripping openings, threaded handles, plastic perforated handles, or no handles at all on the side walls of the box. This makes them inconvenient to handle and prone to slipping. Assembly is cumbersome and consumes a lot of manpower and resources. Since adding handles can affect the stacking and container transportation of multiple boxes, even if some packaging boxes have handles, they are mostly made of plastic. Moreover, most boxes are usually sealed with transparent tape, which is neither convenient nor environmentally friendly for recycling. In addition, some beverage boxes have top openings and side walls that are higher than the beverage bottles to facilitate stacking and transportation, but the top openings of the boxes can easily cause the beverages inside to fall out and break. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a method for manufacturing a carrying box that is easy to fold and transport, which can facilitate stacking and transportation while also being easy to carry and use, reducing the use of glue.

[0004] A method for manufacturing a handbag that is easy to fold and transport according to a first aspect of the present invention includes: manufacturing a blank, assembling side panels, sealing the bottom plate, and sealing the top plate;

[0005] To create a blank, a piece of cardboard is stamped and cut out.

[0038] Reference Figures 1 to 5 A method for manufacturing a handbag that is easy to fold and transport includes: making a blank, assembling side panels, sealing the bottom plate and sealing the top plate;

[0039] To create a blank, a piece of cardboard is punched and cut out. The blank includes a first side plate 100, a second side plate 200, a third side plate 300, a fourth side plate 400, a base plate assembly 500, an auxiliary plate 600, and a sealing plate 700, which are connected in sequence. There are two auxiliary plates 600. One of the auxiliary plates 600 is folded and connected to the upper part of the second side plate 200, and the other auxiliary plate 600 is folded and connected to the upper part of the fourth side plate 400. The sealing plate 700 includes an extension piece 710 that passes through a first crease 74. The first side plate 100 is folded and connected; the flat folded piece 720 is folded and connected to the extension piece 710 through the second fold 750, and the extension piece 710 is used to adapt the flat folded piece 720 to a predetermined height; the insert piece 730 is folded and connected to the flat folded piece 720 through the third fold 760, and the third fold 760 has a hand hole 770; two encapsulation plates 700 are provided, one of which is folded and connected to the upper part of the first side plate 100, and the other of which is folded and connected to the upper part of the third side plate 300.

[0040] The steps also include: side panel assembly, folding the first side panel 100, the second side panel 200, the third side panel 300 and the fourth side panel 400 together, and bonding the first side panel 100 and the fourth side panel 400 together to form the side wall of the handbag.

[0041] Base plate encapsulation: The various base plates in the base plate assembly 500 are folded together to fit the bottom of the encapsulated carrying case.

[0042] The top plate is sealed by folding two auxiliary plates 600 towards each other. Each auxiliary plate 600 has a portion of a slot 610. When the two auxiliary plates 600 are folded, the slots 610 are symmetrically distributed on the two auxiliary plates 600. The extension piece 710 is folded along the first crease 740, and the flat fold piece 720 is folded along the second crease 750 to form the top of the carrying case. The insert piece 730 is folded downwards through the third crease 760 and inserted into the slot 610. The auxiliary plates 600 help to restrain the beverage bottle in a predetermined position and reduce misalignment space. The extension piece 710 facilitates the adjustment of the distance of the flat fold piece 720. The extension piece 710 forms a predetermined angle with the side plate, making the flat fold piece 720 easier to bear force. The insert piece 730 surrounds the entire carrying case together. The use of multiple mating structures reduces the use of glue and facilitates assembly.

[0043] The auxiliary plates on the second side plate 200 and the fourth side plate 400 have openings 620 for fitting. When the auxiliary plates are folded, the openings 620 pass through the bottle neck and fit over it, thus confining the beverage bottle to a predetermined position and reducing misalignment. This prevents misalignment during assembly, transportation, and handling, which could lead to bottle breakage. The sealing plates 700 on the first side plate 100 and the third side plate 300 enable the carrying case to serve multiple purposes. The extension pieces 710 on the first side plate 100 and the third side plate 300 facilitate adjusting the flat folding piece 720 to smoothly abut against the bottle cap during the top plate sealing step. When the carrying case is used for handling... The two inserts 730 are attached together, and the handles on the inserts 730 increase the force-bearing area, dispersing the force and potentially preventing finger cuts. The extension piece 710 forms a predetermined angle with the first side plate 100 and the third side plate 300. Whether during packaging and transportation or during handling, the extension piece 710 and the flat folding piece 720 make the carrying box easier to bear the force. This carrying box utilizes multiple interconnected structures to reduce the use of glue, facilitate assembly and forming, and also achieve environmental protection. It is understood that the top plate includes two packaging plates 700 and two auxiliary plates 600.

[0044] In some embodiments, an arc-shaped guide structure 731 is provided at the corner of the insertion end of the insert 730, and slots 732 adapted to the slot 610 are provided on both sides of the insert 730. The arc-shaped guide structure 731 is used to guide the insert 730 into the slot 610. The insert 730 and slot 610 facilitate the reinforcement and assembly of the carrying case. It can be understood that the arc-shaped guide structure 731 can also be set as a slope. The slots 732 are locked on the auxiliary plate 600, which can not only meet the requirements of sealing and rotating connection, but also use the support of the auxiliary plate 600 and the bottle body to prevent the flat folding piece 720 from collapsing, which facilitates the stacking of multiple carrying cases.

[0045] In some embodiments, arc-shaped positioning structures 611 are provided on both sides of the slot 610. Two inserts 730 are folded downward through the third crease 760. The arc-shaped guide structure 731 guides the inserts 730 into the slot 610. The slot 732 engages with the arc-shaped positioning structure 611. One end of the slot 732 abuts against the lower side of the auxiliary plate 600. The arc-shaped positioning structure 611 facilitates the downward sliding of the arc-shaped guide structure 731, making the assembly efficiency higher.

[0046] In some embodiments, the hand hole 770 includes a holding portion 771 formed on the insert 730. The holding portion 771 is used for holding, and the holding portion 771 is provided for easy gripping. It can be understood that the holding portion 771 is provided with three arc-shaped recesses. The three arc-shaped recesses are convenient to avoid the back of the hand when holding and using. At the same time, there may be a number of arc-shaped recesses.

[0047] In some embodiments, the hand hole 770 also includes a contoured portion 772, which is formed on the flat fold 720 and is connected to the carrying portion 771. The contoured portion 772 is used to avoid fingers. It can be understood that when pulling out the insert 730, the flat fold 720 is gripped and the insert 730 is pulled out using the lever principle, which is more effortless. In addition, after the top plate sealing step, the loading status inside the carrying case can be observed through the contoured portion 772, for example, the bottleneck of the sleeve 620, which is convenient to observe.

[0048] In some embodiments, the hand hole 770 is configured as several independent through holes to avoid fingers.

[0049] Reference Figure 4 The two inserts 730 are folded upwards through the third fold 760. The two handles 771 are symmetrically arranged, and the two contoured parts 772 are symmetrically arranged. When carrying the box, the two contoured parts 772 avoid the fingers. The third fold 760 makes it easy for the inserts 730 to fold downwards or upwards. It can be understood that the two contoured parts 772 are symmetrically arranged so that the box is evenly stressed and does not deviate to one side when carried.

[0050] In some embodiments, during the base plate encapsulation step, the base plate assembly 500 includes a first base plate 510, a second base plate 520, a third base plate 530, and a fourth base plate 540. The first base plate 510 is connected to the lower part of the first side plate 100, the second base plate 520 is connected to the lower part of the second side plate 200, the third base plate 530 is connected to the lower part of the third side plate 300, and the fourth base plate 540 is connected to the lower part of the fourth side plate 400. The first base plate 510 is provided with a rectangular slot, the second base plate 520 and the fourth base plate 540 are provided with hook-shaped structures, and the third base plate 530 is provided with a plug-in structure. During folding, the first base plate 510 is folded first, then the hook-shaped structure is inserted into the rectangular slot, and finally the plug-in structure is inserted into the rectangular slot to press down the second base plate 520 and the fourth base plate 540, thereby completing the base plate encapsulation.

[0051] In some embodiments, the extension piece 710 and the flat fold piece 720 are both narrowed into trapezoids, and the insert piece 730 is set as a rectangle. It can be understood that the extension piece 710, the flat fold piece 720 and the insert piece 730 can all be trapezoids that narrow upwards. The trapezoidal extension piece 710 and the flat fold piece 720 can make the carrying case evenly stressed while reducing the use of consumables. The channel defined between the two flat fold pieces 720 and the two auxiliary plates 600 has an indentation. The upper edge of the indentation is formed by the waist of the two trapezoidal flat fold pieces 720 on the same side to detect whether the stress is stable when stacking. When the two carrying cases are stacked together, if an offset occurs, it means that the two carrying cases are not aligned in the vertical direction, so that the operator can re-stack them.

[0052] In some embodiments, the auxiliary plate 600 has a plurality of sleeve holes 620 for fitting the bottleneck.

[0053] In some embodiments, a plurality of holes 620 are symmetrically distributed along the extension direction of the slot 732. The symmetrically distributed holes 620 are used to distribute the force. It is understood that the holes 620 can be waist-shaped holes, circular holes, rectangular holes, trapezoidal holes, or holes that imitate the shape of a bottleneck, etc.

[0054] In some embodiments, a waterproof layer is added during the fabrication of the blank to facilitate transportation and use.
