Abstract

The utility model relates to a packaging carton which is composed of a bottom cover, a surrounding plate, a top cover and H-shaped splicing pieces. The coaming is of a frame-shaped structure, a main body of the H-shaped splicing piece is strip-shaped, and the width of an upper groove and a lower groove of the H-shaped splicing piece is not smaller than the thickness of the coaming, so that the coaming can be inserted into the H-shaped splicing piece. When the packaging box is used, the box wall of the packaging box is formed by vertically stacking the surrounding plates, and the stacking joints of the surrounding plates are spliced through the H-shaped splicing pieces. The specific implementation of splicing is as follows: the upper end part of the lower coaming is inserted into a lower groove of the H-shaped splicing piece, and the lower end part of the upper coaming is inserted into an upper groove of the H-shaped splicing piece. The corrugated boards have the property of being prone to bending deformation in the longitudinal direction, the risk of bending deformation of the corrugated boards can be reduced through the bending resistance of the splicing pieces of the H-shaped structures, and therefore the overall impact resistance of the box body is improved. The height of the packaging box is determined by the number of longitudinally-stacked layers of the surrounding plates of the surrounding frame type structure, and in application, the height of the packaging box is changed by changing the number of the stacked layers of the surrounding plates.

Description

Technical Field

[0001] The utility model relates to a packaging carton, and is particularly suitable for the field of collective packaging cartons in which multiple articles are packed in one packaging box. Background Art

[0002] At present, packaging cartons usually consist of three parts: bottom cover, box wall and top cover. The height of the box wall determines the height of the packaging box. When multiple items are packed in one packaging box, different loading quantities will have different requirements for the height of the packaging box. The collective packaging of multi-specification items, the collective packaging of sundries, and the collective packaging of moving items often have uncertainties in the height requirements of the packaging boxes. Due to the existence of the above situation, collective packaging cartons of the same specification are difficult to meet application needs. When the packaging carton is used as the outer box of the pallet packaging, because the standard length and width dimensions of the pallet in my country are mainly 120×100cm and 110×110cm, this standard size of pallet is the most widely used. When the standard pallet is used for collective packaging, the height of its pallet outer box will determine the capacity of the pallet packaging. A pallet outer box that is too low will not meet the application needs; a pallet outer box that is too high will increase the logistics volume and waste social resources.

[0003] In order to cope with the uncertainty of the contents of the collective packaging cartons, people usually deal with it by producing cartons of various heights and specifications to meet the packaging needs. The disadvantage of this response method is that it increases the production and storage costs, and the fixed-specification packaging cartons have poor adaptability.

[0004] In view of the shortcomings of the above-mentioned background technology, some industry personnel have adopted a contingency plan. For example, in the process of domestic long-distance moving and international moving services, in order to increase the safety of items during logistics transportation, people stack the moved items on pallets and add boxes around and on top of the items. The boxes are usually made of multiple sheets of corrugated cardboard that are manually cut, bent, and spliced ​​on site. The cardboard is cut, bent, and sealed according to the stacking height of the items on the pallet. This contingency plan solves the application needs of the uncertainty of the contents of the collective packaging box, but the manual operation workload is large, especially when heavy-duty cardboard is used, which will be more time-consuming and labor-intensive. At the same time, the aesthetics of the finished product is often difficult to meet the application needs. Summary of the invention

[0005] In order to overcome the shortcomings of existing packaging cartons, the utility model provides a packaging carton with a variable height. When the packaging carton is used as a collective packaging box, it can meet the needs of different quantities and specifications of internal contents for the adjustable height of the packaging carton, and at the same time can improve the adaptability of the collective packaging box.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the utility model is a packaging carton composed of a bottom cover, a panel, a top cover, and an H-shaped splicing piece. The panel is a frame-like structure, and the main body of the H-shaped splicing piece is strip-shaped, and the width of the upper and lower grooves is not less than the thickness of the panel, so as to ensure that the panel can be inserted therein. When in use, the box wall of the packaging box is formed by stacking the panels up and down, and the overlapping joints of the panels are spliced ​​by the H-shaped splicing piece. The specific implementation of the splicing is: the upper end of the lower panel is inserted into the lower groove of the H-shaped splicing piece, and the lower end of the upper panel is inserted into the upper groove of the H-shaped splicing piece. Corrugated cardboard has the property of being easy to bend and deform longitudinally. The bending resistance of the splicing piece of the H-shaped structure itself will reduce the risk of bending and deformation of the corrugated cardboard, thereby improving the overall impact resistance of the box. With the help of adhesive tape reinforcement, the vertical wall of the H-shaped splicing piece is bonded to the panel, so as to further improve the firmness of the panel splicing. The number of longitudinally stacked layers of the frame-like structure determines the height of the packaging box. In application, the height of the packaging box is changed by changing the number of stacked layers of the frame.

[0007] To further explain, the H-shaped splicing piece is one of metal materials and non-metal materials. Adding hollow holes and notches to the groove wall and groove bottom of the H-shaped splicing piece will achieve the effect of reducing weight and saving materials; adding screw holes to the groove wall of the H-shaped splicing piece will facilitate adding screw reinforcement in subsequent splicing.

[0008] Further explanation: H-type splicing pieces are divided into H-type straight splicing pieces and H-type corner splicing pieces. H-type corner splicing pieces are used for upper and lower splicing at the corners of the enclosure, which will further improve the splicing strength and aesthetics; when only H-type straight splicing pieces can meet the application needs, the corner splicing pieces are cancelled to simplify the packaging process; the physical properties of H-type splicing pieces are one of one-piece and segmented splicing pieces. When it is a segmented splicing piece, the mutual overlap and engagement of its joints will better retain the bending resistance of the H-type splicing piece.

[0009] It is further explained that a transverse spare indentation is added to the enclosure, and the enclosure is bent inward along the spare indentation during use, so that the height of the enclosure can be lowered, thereby realizing the function of fine-tuning the height of the packaging box.

[0010] Further explanation: the enclosure panels with frame structure are spliced ​​by sealing nails, screws, glue, tape, or holes and fasteners before leaving the factory. When the length and width are large, no pre-splicing is done before leaving the factory, so as to better fold and stack, so as to facilitate subsequent transportation and logistics delivery. During the packaging implementation, the panels are spliced ​​on site by using tape, glue, nails, or fasteners.

[0011] Further description, the utility model is a packaging carton, the box bottom is divided into two forms, one is a box bottom with a tray, and the other is a box bottom without a tray.

[0012] Further explanation, the utility model is a packaging carton, and its main forms are divided into two types, one is a rocker lid box, and the other is a top and bottom lid box. When the main form is a rocker lid box, the lid of the packaging box is a rocker lid, and in order to achieve the fixation of the rocker lid, the rocker lid is connected to a panel as a whole. When used in conjunction with a pallet, when a bottom rocker lid is not required, a packaging box needs to be equipped with a rocker lid with a panel for the top. When a bottom rocker lid is required, a packaging box needs to be equipped with two rocker lids with panels, one of which is inverted at the bottom after sealing, with the rocker lid at the bottom and the connected panel at the top, and the other is used for the top of the packaging box. The number of panels equipped is determined by the height of the contents.

[0013] Further explanation, the utility model is a packaging carton, the main body of which is a top and bottom cover box. Its main structure includes: an upper top cover, a lower bottom cover, a panel, and an H-shaped splicing piece. When used in conjunction with a pallet, if the lower bottom cover can meet the application requirements, the lower bottom cover is cancelled. The number of panels is determined by the height of the contents.

[0014] It is further explained that in a packaging carton of the utility model, when the height of the frame-shaped enclosure is more than one specification, the adjustability of the height of the packaging box will be further increased.

[0015] Further description, the utility model is a packaging carton, which is applicable to the field of carton packaging and also applicable to the field of hollow board packaging boxes. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Embodiment 1

[0047] Figure 1 , Figure 2 In the figure, the H-shaped straight strip splicing piece (1) is in the shape of a straight strip, presenting a double groove structure with two upper and lower parts sharing the same bottom; Figure 5 , Figure 6 , Figure 7 In the embodiment, the H-shaped corner splicing piece (2) is in a right-angle shape, and the corner and its vicinity present a double groove structure with two upper and lower common bottoms. The two extended areas have only vertical walls without bottom grooves, and the thickness of the vertical walls is reduced so that the inner width of the two walls is not less than the outer distance between the two vertical walls of the H-shaped straight strip splicing piece (1), thereby ensuring that the H-shaped straight strip splicing piece (1) can be inserted and engaged therein, thereby ensuring that the H-shaped straight strip splicing piece (1) and the H-shaped corner splicing piece (2) can be butted against each other.

[0048] Figure 8 , Fig. 9 , Fig.10 In the middle, there is a panel (11) formed by stacking corrugated cardboard after being crimped and bent; Fig.11 In the embodiment, there are two openings at the indentation of the splicing area of ​​the enclosure (11), which are tape holes (10) for the tape to pass through when the subsequent enclosure (11) is closed.

[0049] Fig.12 , Fig.13In the process, the bottom cover (12) is placed on the top of the tray (6), and the packaging (8) is stacked on the top of the bottom cover (12). The reverse-adhesive double-sided adhesive tape (3) with the patent authorization announcement number CN219824053U is passed through the tape hole (10) on the enclosure (11) and attached to the inner side of the enclosure (11). The enclosure (11) is closed head to tail, and the isolation paper at the exposed end of the reverse-adhesive double-sided adhesive tape (3) is torn off and tightened, and then the reverse-adhesive double-sided adhesive tape is attached to the outer side of the closed end, so that the enclosure (11) is closed head to tail.
