A packaging box and a method for folding a box

Abstract

The present invention provides a packaging box and a box folding method, wherein the packaging box includes a pin and a slot for inserting the pin, with cutouts formed on either side of the slot. When the pin is inserted into the slot, the packaging box material near the slot is squeezed, and the material is deformed by the force applied to the material, causing the packaging box material to support the pin, preventing the pin from being dislodged from the slot and also preventing the pin from protruding outward. The novel box structure of the present invention effectively utilizes internal space, reduces the volume of the outer box, and saves on storage and transportation costs. The box of the present invention provides excellent protection for test reagent plates during international long-distance transportation and reduces transportation costs.

Description

Technical Field

[0001] The present invention relates to the technical field of cartons, and in particular to a structure of an airplane box and a box folding method. Background Art

[0002] The airplane box is named because its unfolded shape resembles an airplane. It is a type of cardboard box used to package goods, such as packaging boxes for long-distance transportation of test reagent panels.

[0003] like Figure 1 and 2 As shown, a commercially available airplane box 100 comprises a cover 1, with front side panels 2 on either side. A front baffle 4 is located at the front end of the cover. Front baffle tongues 5 are connected to the ends of the front baffle, and a front buckle 6 is located in the middle of the front end of the front baffle. The cover 1 is connected to a base plate 8 via a rear panel 7. Rear panel tongues 3 are located on either side of the rear panel 7. The base plate is provided with outer panels 9 on either side, which are connected to inner panels 10 with pins. Pins 11 are located at the front end of the inner panels. After the inner panels are folded over, the pins insert into slots 12 on the base plate. A front panel 13 is connected to the base plate. The connection between the front panel 13 and the base plate 8 provides a buckle hole 14 for the front buckle 6. Front panel tongues 15 extend from either side of the front panel. After the edge of the airplane box is folded, the pins 11 insert into the slots 12 on the base plate. After the folding is completed, the outer panel 9 and the inner panel 10 both have an outward rebound force at the fold line. The pins are pulled by these two rebound forces and will pop out of the slot, causing the box folding to fail. Aircraft boxes on the market generally use extended pins to prevent the pins from popping out of the slot.

[0004] like Figure 2 and Figure 3 As shown, after the airplane box is folded and formed, pins 11 are inserted into slots 12 in the bottom plate, protruding from the box's bottom plate 8. The extended pins extend from the slots, but the limited resilient force of the outer and inner panels 9 and 10 is insufficient to eject them. If the pins are not long enough, the probability of them ejecting after folding is very high, reaching as high as 60%, affecting folding efficiency on the production line. Therefore, lengthening the pins is generally used to address this issue.

[0005] The method of lengthening the pins can solve the problem of the pins popping out relatively simply and directly. However, if you encounter a particularly flat box and there are restrictions on the height inside and outside the box, the pins cannot be made very long. Therefore, the method of lengthening the pins cannot be applied to flat boxes with restrictions on the box height.

[0006] During transportation, such aircraft boxes with pins protruding from the bottom plate may also encounter some problems. For example Figure 4As shown, when stacking multiple boxes, the protruding pins increase the total height of the stacked boxes. Furthermore, only the pins of the upper box contact the box below, leaving a very small contact area between the two stacked boxes. This makes it easy for the upper box to fall, and the squeezing force generated by the stacking can cause the pins protruding from the bottom plate to bend and collapse.

[0007] Therefore, it is urgent to design a new structure of the aircraft box to solve these problems in the flat box folding molding and loading and transportation process. Summary of the Invention

[0008] In order to solve the problems of airplane boxes on the market, the present invention provides a packaging box. The packaging box includes a pin and a slot for inserting the pin, and a pressing component is provided adjacent to the slot.

[0009] Furthermore, cutouts are provided on both sides of the slot, and a pressing component is formed between the two cutouts.

[0010] Furthermore, the incisions are incisions that penetrate the packaging box material in a vertical direction at both ends of the slot.

[0011] Furthermore, the pressing component rests against the pins.

[0012] Furthermore, the pin is inserted into the slot and does not protrude from the slot.

[0013] Furthermore, the slot is provided on the bottom plate of the packaging box, the pin is provided on the inner plate, and the inner plate is connected to the bottom plate through the outer plate.

[0014] The present invention provides a method for folding a packaging box. The packaging box includes pins and slots for inserting the pins. A pressing component is provided adjacent to the slots. The pins are inserted into the slots to press the pressing component. The packaging box material is deformed under stress so that the pressing component presses against the pins.

[0015] Furthermore, cutouts are provided on both sides of the slot, and a pressing component is formed between the two cutouts.

[0016] Furthermore, the incisions are incisions that penetrate the packaging box material in a vertical direction at both ends of the slot.

[0017] Furthermore, the pin is inserted into the slot and does not protrude from the slot.

[0018] The beneficial effects of the present invention are as follows: The new structure of the airplane box of the present invention shortens the pins so that they do not protrude from the bottom of the box, making the bottom of the box flatter and improving the user experience. At the same time, by making an incision at the slot, the deformed bottom plate supports the pins, thereby achieving a locking function between the pins and the socket, preventing the pins from being disengaged from the slot and the inner panel from popping open. When the overall height of the box is limited, the new box structure of the present invention can maximize the effective use of the internal space. The new box structure of the present invention maximizes the effective use of the box volume, reduces the volume of the outer box, and saves storage and transportation costs.

[0034] The present invention will be described in detail below with reference to the accompanying drawings. These specific embodiments are merely limited examples without departing from the spirit of the present invention, and do not exclude other specific implementation plans that can be produced by combining the prior art with the present invention by those skilled in the art.

[0035] like Figure 5 As shown, the aircraft box 101 of the present invention comprises a cover 1, with front side panels 2 provided on either side of the cover, a front baffle 4 provided at the front end of the cover, front baffle tongues 5 connected at both ends of the front baffle, and a front buckle 6 provided at the center of the front end of the front baffle. The cover 1 is connected to a base plate 8 via a rear panel 7, with rear panel tongues 3 provided on either side of the rear panel. The base plate is provided with outer panels 9 on either side, which are connected to an inner panel 10 with pins. Pins 17 are provided at the front end of the inner panel 10, which, after folding over, insert into slots 12 provided on the base plate. A front panel 13 is connected to the base plate 8. A buckle hole 14 for the front buckle 6 is defined at the junction of the front panel 13 and the base plate 8. Front panel tongues 15 extend from each side of the front panel 13.

[0036] Figure 5 As shown, a cutout 16 is added to the slot 12, so that the bottom plate adjacent to the slot 12 forms a pressing component 81 that can be pressed down. Figures 5 to 8 As shown, a notch 16 is provided along the extension of the end edge 121 of the slot 12, extending all the way to the slot. One method for forming the notch is to make two perpendicular notches at either end of the slot, penetrating the bottom of the box. The notch length is 8-10 mm, and the length will vary depending on the box size. After the notch is created, the downward pressing member 81 is deformed downward by the compression of materials such as cardboard and corrugated paper, which deform under stress.

[0037] like Figure 7 and Figure 8 As shown, after the aircraft box is folded and formed, the pin 17 is inserted into the slot 12. The pin is substantially at the same height as the box bottom and does not protrude from the box bottom. The pressing component adjacent to the slot is lower than the pin.

[0038] According to the conventional box folding method, the non-lengthened pin 17 is inserted into the slot 12. After the box is folded, the probability of the pin popping out is very high. To avoid this phenomenon, the present invention uses an additional cutout 16 at the slot and improves the box folding method.

[0039] In a box folding method of the present invention, for example, during the folding process, a pin 17 is inserted into a slot 12, at which point the pin is substantially flush with the bottom plate at the cutout. Then, a finger squeezes a pressing member 81 at the cutout 16, slightly pushing the pressing member 81 inward 1-2 mm toward the inside of the box. The squeezing force causes the bottom plate at the cutout (pressing member 81) to bend downward, creating a height difference between the pin and the bottom plate at the deformed cutout, thereby achieving a locking function between the pin and the socket.

[0040] like Figure 9 and 10 As shown, the outer and inner panels 9 and 10 are folded over, and the pins are inserted into the slots. The downwardly bent pressing member 81, pressed against the inner panel 10 or the pins, prevents the rebound force of the outer and inner panels 9 and 10 from causing the pins to pop out of the slots. This creates a height difference between the pins 17 and the bottom plate at the deformed cutout, effectively increasing the pins' extended length. This prevents the pins from popping out of the slots after the folding box is formed, while also ensuring that the overall height of the box remains unchanged.

[0041] like Figure 11 As shown, the pins of the aircraft box of the present invention do not protrude from the bottom of the box, which makes the bottom of the box flatter. When the boxes are stacked together, the boxes are more tightly pressed against each other, which reduces the total height of the stacked boxes. This can reduce the volume of the outer box containing these aircraft boxes, save storage space and expenses, and reduce transportation costs.

[0042] When the box height is not limited or can meet the height limit requirements, the pins can also be designed to protrude from the bottom of the box.

[0043] It has been verified that, without adding pins, a box formed by folding the edges using the method of the present invention can prevent the pins from popping out of the slots.

[0044] The cutout can be in the same straight line with the end edge of the slot, or can be at a certain angle to the slot, such as 45-135°. Figure 12 and 13 shown.

[0045] like Figure 14 and 15 Another aircraft box structure of the present invention is shown. Figure 14 The aircraft box and Figure 5 The structure of the aircraft box shown is basically the same. Figure 14 The aircraft box does not use the cutting method.

[0046] like Figure 14 and 15As shown, first punching lines 19 are provided on the extension lines of the two end edges 121 of the slot 12, and second punching lines 20 connected to the end points of the first punching lines 19 extend to the slot. When folding the box, a pressing member 81 is stamped and formed on the bottom plate near the slot. The pressing member 81 presses against the inner panel 10 or the pin 17, preventing the rebound force of the outer panel 9 and the inner panel 10 from causing the pin to pop out of the slot.
