Description

Technical Field

[0001] The utility model relates to a packaging box, in particular to an isolation tape-free packaging box. Background Art

[0002] Corrugated boxes are widely used packaging containers for the transportation and storage of various goods. They are primarily made of corrugated cardboard. These boxes are typically sealed with tape, which is primarily made of plastic and is difficult to degrade, causing significant environmental pollution. With the increase in express delivery volume, tape usage has also skyrocketed, resulting in a large amount of plastic waste that is difficult to dispose of. Furthermore, when using boxes to transport fragile items that require isolation, such as agricultural products, separators are added to the box to isolate the items. These separators must be adapted to the size of the box, reducing the cardboard's utilization rate. Utility Model Content

[0003] The purpose of the utility model is to provide an isolation tape-free packaging box to solve the problems of environmental pollution caused by using tape packaging in existing packaging boxes and low cardboard utilization rate.

[0004] The technical solution of this utility model is as follows:

[0005] An isolation tape-free packaging box, comprising a side surrounding portion and a box bottom portion located on both sides of the side surrounding portion, the side surrounding portion being composed of four side panels connected in sequence, wherein the outer side panels are provided with overlapping edges, and the four bottom panels constituting the box bottom portion are respectively connected to the corresponding four side panels, and the bottom panel is composed of two outer panels and two inner panels arranged at intervals, and packaging tongues are provided on both the inner and outer panels, and a first plugging groove for plugging the packaging tongue of the outer panel is provided on the inner panel, a second plugging groove communicating with the first plugging groove of the inner panel is provided on the packaging tongue of the inner panel, and a third plugging groove is provided on the edge portion of the packaging tongue; the second plugging groove and the third plugging groove of the inner panel connected to the same side panel overlap with each other.

[0006] Furthermore, the second plug-in slot extends inward from the junction of the packaging tongue and the inner plate.

[0007] Furthermore, a third plugging slot is formed on the packaging tongue of the inner plate, and two third plugging slots are formed on the packaging tongue of the outer plate.

[0008] Furthermore, the third plugging slot extends inward from the outer edge of the packaging tongue, and the second plugging slot and the third plugging slot are respectively located on the left and right sides of the packaging tongue.

[0009] Furthermore, the packaging tongue of the outer plate is plugged into the first plugging slots on the two inner plates. The packaging tongue on the outer plate is divided into three parts by the third plugging slot. The length of the outer part is the same as the height of the inner plate to which it is plugged.

[0010] Furthermore, the length of the packaging tongue is the same as that of the side panel, and the packaging tongue is connected to the outer end edge of the outer panel or the inner panel.

[0011] Furthermore, curtain-type ventilation holes are provided on the four side panels.

[0012] Furthermore, a circular vent hole is provided on the packaging tongue.

[0013] This new packaging box is based on a traditional semi-overlapping structure, and its production process and equipment do not need to be updated, thus saving production costs. The circular vents and curtain-style vents provide a better ventilation design, ensuring the freshness of fruits and vegetables. The plug-in slots and sealing tongues seal the top and bottom surfaces of the packaging box, while also dividing the space within the box. This ensures packaging efficiency and firmness, eliminates the need for adhesive tape, reduces environmental pollution and resource waste, and eliminates the need for separate isolation panels for the packaging box, improving cardboard utilization. The entire packaging box is made of a single paper material, making it easy to recycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1 As shown, the utility model includes a side surrounding part and a box bottom part located on both sides of the side surrounding part. The side surrounding part is composed of four side panels 1 connected in sequence, wherein the outer side panel 1 is provided with an overlapping edge 2, and the four bottom panels constituting the box bottom part are respectively connected to the corresponding four side panels 1, and the bottom panel is composed of two outer panels and two inner panels arranged at intervals, that is, arranged in the order of a first outer panel 3, a first inner panel 4, a second outer panel 5 and a second inner panel 6.

[0019] Among them, a first plug-in slot 9 is opened on the first inner plate 4 and the second inner plate 6, the first plug-in slots 9 on the first inner plate 4 and the first inner plate 6 on the same side of the box bottom correspond to each other and are connected to each other, and a packaging tongue is provided on the first outer plate 3 and the second outer plate 5, and the packaging tongues on the outer plates on the same side of the box bottom are all plugged into the first plug-in slots 9 on the inner plates.

[0020] A packaging tongue is provided on each inner plate 4. The length of the packaging tongue is the same as the length of the connected bottom plate. A third plugging groove 11 is opened on the packaging tongue. The third plugging groove 11 extends toward the center from the edge of the packaging tongue. When the first inner plate 4 and the second inner plate 6 are folded inward, the packaging tongues on the first inner plate 4 and the second inner plate 6 form partitions parallel to each other.

[0021] The packaging tongue on the inner panel is also provided with a second plug-in slot 10. When the inner panel is folded inward, the packaging tongues of the inner panel connected to the same side panel overlap with each other, and the second plug-in slot 10 on one inner panel overlaps with the third plug-in slot 11 on the inner panel of the other side box bottom, and is used to be plugged into the third plug-in slot 11 on the outer panel.

[0022] The length of the first plug-in slot 9 is the height of the inner plate where the slot is located, the length of the second plug-in slot 10 is less than the height of the package tongue where the slot is located, and the length of the third plug-in slot 11 is less than the height of the package tongue where the slot is located.

[0023] When the outer panel folds inward, the sealing tongues on the outer panel and the inner panel become perpendicular and interlock, forming a partition perpendicular to the inner panel's sealing tongues. Two third insertion slots are provided on the outer panel's sealing tongues, dividing them into three sections. The outer portion of the outer panel's sealing tongues plugs into the first insertion slots 9 on the inner panel, while the middle portion plugs into the space formed by the sealing tongues of the first inner panel 4 and the second inner panel 6. The outer panel overlays the inner panel, and the length of the divided outer portion of the sealing tongues is the same as the height of the inner panel it plugs into. The sealing tongues of the first outer panel 3 and the second outer panel 5 overlap, further strengthening the partition.

[0024] The height of the packaging tongue is the same as that of the side panel 1 , and the length of the packaging tongue is the same as that of the side panel 1 connected to the inner panel or outer panel where the packaging tongue is located.

[0025] The four side panels 1 of the packaging box can be the same length. The third insertion slot 11 on the inner panel's sealing tongue can be located at one-third or two-thirds of the tongue. The two third insertion slots on the outer panel's sealing tongue can be located at one-third and two-thirds of the tongue, respectively. Dividing the tongue into three equal parts, nine small cubic packaging boxes can be formed. The length of the four side panels 1 of the packaging box is adjustable, and the third insertion slot 11 can be located at other positions on the tongue. The specific length of the four side panels 1 and the position of the third insertion slots can be adjusted according to actual conditions.

[0026] Curtain-type ventilation holes are provided on the four side panels 1, and circular ventilation holes are provided on the packaging tongue.

[0027] All planes of the carton can be fully displayed in the unfolded view, so the entire carton can be made with only one piece of cardboard, with high material utilization and low production cost.

[0028] The packaging steps for the packaging box are as follows:

[0029] Step 1: First, four side panels 1 are arranged in a circle, and the overlapping edges 2 are overlapped on the edges of adjacent side panels 1 and fixed by bonding to form a side surrounding part.

[0030] Step 2: If Figure 2 As shown, the first inner panel 4 is folded inward so that the first inner panel 4 and the connected side panel 1 are perpendicular, and the packaging tongue on the first inner panel 4 is further folded inward so that the packaging tongue on the first inner panel 4 and the side panel connected to the first inner panel 4 are parallel; the second inner panel 6 is folded inward so that the first inner panel 4 and the connected side panel 1 are perpendicular, and the packaging tongue on the first inner panel 4 is further folded inward so that the packaging tongue of the first inner panel 4 and the side panel connected to the first inner panel 4 are parallel.

[0031] Step 3: If Figure 3 As shown, the first outer panel 3 and the second outer panel 5 are folded inward so that they are perpendicular to the side panels connected to them, and the first outer panel 3 and the second outer panel 5 are covered on the first inner panel 4 and the second inner panel 6. First, one bottom of the box is sealed, and after the items are loaded, the other bottom of the box (which is actually the top of the box) is sealed. No tape is used in the entire sealing process. Only the upper and lower four outer panels are plugged into each other to form a relatively strong interlocking structure.
