Abstract
Description
Technical Field
[0001] This utility model relates to the field of product packaging technology, and in particular to a cardboard box. Background Technology
[0002] Currently, cardboard boxes are widely used in the product packaging industry due to their advantages such as light weight, low cost, and ease of processing and transportation. They have become a common transportation auxiliary material in fields such as dairy processing, logistics and transportation, and pharmaceuticals.
[0003] In practical applications, cardboard boxes are usually equipped with hand holes to facilitate manual handling. However, the existing hand hole design is unreasonable. Due to the high rigidity of cardboard boxes, and the fact that the hand holes are usually made by stamping, the edges of the hand holes are relatively sharp. When the handler's hand goes through the hand hole to handle the goods, the contact area between the hand and the hand hole is prone to causing obvious pain due to the sharpness of the hand hole, which affects the handler's ability to handle the cardboard box. Utility Model Content
[0004] This utility model provides a cardboard box to at least solve or improve the problem of unreasonable hand hole design in existing cardboard boxes, which easily causes pain to the hands of transporters when handling the cardboard box.
[0005] This utility model provides a cardboard box, comprising:
[0006] The box has a receiving cavity and a hand hole communicating with the receiving cavity, and the hand hole has a force-bearing edge;
[0007] A folding plate has a folded edge, and the folded edge and the force-bearing edge are connected by an indentation groove;
[0008] When the folding plate is in the folded state, at least a portion of the folding plate extends out of the hand hole and is configured to support a hand passing through the hand hole.
[0009] According to the present invention, a cardboard box has a hand hole located on the side wall of the box body and extending along the width direction of the box body.
[0010] Wherein, the force-bearing edge is the top edge of the access hole along the height direction of the box body.
[0011] According to the present invention, the access hole of a cardboard box is a rectangular hole or an oblong hole.
[0012] According to the present invention, a cardboard box is provided in which a first slit and a second slit are further provided between the folding plate and the box body;
[0013] Along the extension direction of the hole wall of the access hole, the first cut, the indentation groove and the second cut are arranged in sequence.
[0014] According to the present invention, in a cardboard box, the extension length of the indentation groove is less than the extension length of the force-bearing edge.
[0015] According to the present invention, the extension length of the indentation groove is 50% to 75% of the extension length of the force-bearing edge.
[0016] According to the present invention, at least one of the first cut and the second cut is a tear line or slit formed between the folding plate and the box body.
[0017] According to the present invention, a cardboard box is provided, wherein the folding panel includes a first plate and a second plate;
[0018] The first side of the first plate and the force-bearing edge are connected by the indentation groove, and the second side of the first plate and the first side of the second plate are connected.
[0019] When the folding plate is in the folded state, the first plate extends out of the access hole, and the second plate is folded relative to the first plate and passes through the access hole.
[0020] According to the present invention, in a cardboard box, the width of the second board is greater than the width of the first board along the extending direction from the first board to the second board.
[0021] According to the present invention, in a cardboard box, the surface area of the folding plate is smaller than the opening area of the access hole;

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0033] The following is combined Figures 1-5 The cardboard box provided by the utility model embodiment will be described in detail through specific embodiments and application scenarios.
[0034] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, this utility model provides a cardboard box, including: a box body 1 and a folding panel 2;
[0035] The box 1 has a receiving cavity 11 and a hand hole 12 communicating with the receiving cavity 11. The hand hole 12 has a force-bearing edge Z1. The folding plate 2 has a folded edge Z2. The folded edge Z2 and the force-bearing edge Z1 are connected by an indentation groove 3.
[0036] When the folding plate 2 is in the folded state, at least a portion of the folding plate 2 extends out of the access hole 12 and is configured to support the hand that passes through the access hole 12.
[0037] It is understood that, depending on the materials used in the actual application, the cardboard box in this embodiment can be a corrugated cardboard box, a white cardboard box, or a paper-plastic composite box; depending on the type of cardboard box structure, the cardboard box in this embodiment can be a PDQ cardboard box (Product Display Quickly) or a double-sided box.
[0038] The housing 1 can be a cubic or cylindrical structure, without specific limitations. The access hole 12 can be located on the side wall, top wall, or bottom wall of the housing 1, without specific limitations. Figure 1 and Figure 4 All illustrations show that the access hole 12 is located on the side wall of the housing 1.
[0039] The housing 1 and the folding plate 2 can be a one-piece structure made of the same material. By connecting the force-bearing edge Z1 of the access hole 12 and the folded edge Z2 of the folding plate 2 through the indentation groove 3, the folding plate 2 can be stored in the area where the access hole 12 is located when the folding plate 2 is not folded (see...). Figure 2 and Figure 5 When the movers need to move the carton, they only need to touch the folding plate 2 with their hands to ensure that the folding plate 2 folds relative to the carton body 1 along the indentation groove 3.
[0040] like Figure 1 As shown, when the indentation groove 3 is provided on the outer surface of the box body 1, the folding plate 2 can be folded inward along the indentation groove 3 toward the box body 1. Of course, when the indentation groove 3 is provided on the inner surface of the box body 1, the folding plate 2 can be folded outward along the indentation groove 3 toward the box body 1. Both of these folding designs can extend at least part of the folding plate 2 out of the access hole 12, so as to switch the folding plate 2 from the unfolded state to the folded state.
[0041] In practical applications, by setting the groove depth of the indentation groove 3, for example, the groove depth of the indentation groove 3 shall not exceed 50% of the thickness of the cardboard corresponding to the box body 1, it can be ensured that when the folding plate 2 is in the folded state, the folding angle of the folding plate 2 relative to the box body 1 is less than 90°. This is convenient for the handling personnel to exert force with their hands, and also prevents the folding plate 2 from breaking off from the box body 1 due to excessive folding angle.
[0042] The cardboard box shown in this utility model has a folding plate 2 that can be folded relative to the box body 1 at the force-bearing edge of the hand hole 12. The folding plate 2 can disperse the pressure on the force-bearing edge of the hand hole 12. When the handler carries the cardboard box, the folding plate 2 in the folded state can support the hand when the hand is inserted into the hand hole 12, which increases the force contact area between the hand and the hand hole 12 and effectively reduces the pain caused to the hand by the hand hole 12 when the handler carries the cardboard box.
[0043] In some embodiments, such as Figure 1 and Figure 4 As shown, the access hole 12 is provided on the side wall of the box body 1 and extends along the width direction of the box body 1; wherein, the force-bearing edge is the top edge of the access hole 12 along the height direction of the box body 1.
[0044] Understandably, considering that the box body 1 is usually folded from flat paper pieces, in order to facilitate the folding and assembly of the box body 1, the top and bottom walls of the box body 1 are usually formed by assembling the paper pieces together. Therefore, the side walls of the box body 1 have relatively large structural strength. Thus, the access hole 12 is set on the side wall of the box body 1. This design also makes it easier for the handling personnel to apply force to the box body 1 through the access hole 12, and support the folding plate 2 connected to the force-bearing edge of the access hole 12 with their hands, thereby facilitating the handling of the carton.
[0045] Meanwhile, the handhole 12 can be a rectangular or oblong hole. By designing the handhole 12 to extend along the width of the box body 1, it is easy for the handhole 12 to fit the width of the handler's hand, making it convenient for the hand to be inserted into the handhole 12 for handling the carton. The length of the handhole extending along the width of the box body 1 can be adapted to the width of an adult's palm.
[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, there is a first cut 4 and a second cut 5 between the folding plate 2 and the box body 1; along the extension direction of the hole wall of the access hole 12, the first cut 4, the indentation groove 3 and the second cut 5 are arranged in sequence.
[0047] Understandably, in practical applications, a stamping process can be used to stamp the area where the access hole 12 is located. While constructing an indentation groove 3 between the folding plate 2 and the box 1 based on the stamping head, a first cut 4 can also be constructed on one side of the indentation groove 3 based on the first punch, and a second cut 5 can be constructed on the other side of the indentation groove 3 based on the second punch. This design is simple and convenient to operate and makes it easy to realize the forming process of the folding plate 2.
[0048] At the same time, by setting the first cut 4 and the second cut 5 between the folding plate 2 and the box body 1, it is also convenient for the folding plate 2 to fold smoothly relative to the box body 1 within the access hole 12, and interference between the two ends of the folding plate 2 and the two ends of the access hole 12 can be prevented during the folding process.
[0049] In some embodiments, such as Figure 3 As shown, in order to reduce the folding force on the folding plate 2 and ensure that the folding plate 2 folds relative to the box body 1 along the indentation groove 3, the extension length L1 of the indentation groove 3 is less than the extension length L2 along the force-bearing edge.
[0050] In some embodiments, such as Figure 3 As shown, the extension length L1 of the indentation groove 3 can be set to 50% to 75% of the extension length L2 along the force-bearing edge. For example, L1 can be 50%, 60%, 70%, 75% of L2 or other suitable proportions. This design not only helps to reduce the difficulty of folding the folding plate 2 along the indentation groove 3 relative to the box body 1, but also prevents the folding plate 2 from breaking at the indentation groove 3 due to the excessive cutting size of the first cut 4 and the second cut 5 during the folding process.
[0051] In some embodiments, at least one of the first cut 4 and the second cut 5 is a tear line or slit formed between the folding plate 2 and the housing 1.
[0052] It is understandable that the easy-tear line includes multiple punches formed along the cutting path. When the folding plate 2 needs to be folded, only the force needs to be applied along the extension direction of the easy-tear line to connect the punches corresponding to the easy-tear line, so that the folding plate 2 and the box 1 are separated from each other along the area of the easy-tear line.
[0053] Of course, in practical applications, a punch can also be used to make both the first cut 4 and the second cut 5 slits, with a slit width of 2-3 mm. For example... Figure 2 As shown, when the access hole 12 is an oblong hole, at least part of the first cut 4 and the second cut 5 can be slits extending along an arc path. Figure 5 As shown, when the access hole 12 is a rectangular hole, at least part of the first cut 4 and the second cut 5 can be slits extending along a straight path.
[0054] In some embodiments, such as Figure 4 and Figure 5 As shown, the folding plate 2 includes a first plate 21 and a second plate 22; the first side of the first plate 21 and the force-bearing edge are connected by an indentation groove 3, and the second side of the first plate 21 and the first side of the second plate 22 are connected.
[0055] When the folding plate 2 is in the folded state, the first plate 21 extends out of the access hole 12, and the second plate 22 is folded relative to the first plate 21 and passes through the access hole 12.
[0056] It is understandable that, in order to facilitate the folding of the second plate 22 relative to the first plate 21, a crease can be provided between the first plate 21 and the second plate 22, and the extension direction of the crease is parallel to the extension direction of the indentation groove 3.
[0057] When the folding plate 2 is in the folded state, the first plate 21 and the second plate 22 corresponding to the folding plate 2 are in the folded state. At this time, the angle at which the first plate 21 is folded outward toward the access hole 12 is greater than the included angle between the first plate 21 and the second plate 22 (this included angle is an acute angle). This design allows the second plate 22 to be distributed between the force-bearing edge of the access hole 12 and the hand of the person handling the box 1. The hand applies force to the second plate 22, which increases the force-bearing area of the hand and prevents the hand of the person handling the box from directly contacting the force-bearing edge of the access hole 12, thus avoiding pain to the hand caused by the access hole 12 being sharp.
[0058] In some embodiments, such as Figure 5 As shown, in order to further increase the contact area between the hand and the second plate 22, the width W2 of the second plate 22 can be set to be greater than the width W1 of the first plate 21 along the extension direction from the first plate 21 to the second plate 22.
[0059] In some embodiments, such as Figure 2 and Figure 5 As shown, the surface area of the folding plate 2 is smaller than the opening area of the access hole 12. This design makes it easier for the handler's hand to reach into the access hole 12 to control the folding plate 2 to fold relative to the box body 1 along the indentation groove 3.
[0060] like Figure 2 As shown, when the folding plate 2 is in the unfolded state, the folding plate 2 is located inside the access hole 12. At this time, along the projection direction perpendicular to the wall where the access hole 12 is located, the projected area of the folding plate 2 is smaller than the projected area of the access hole 12. For example, the projected area of the folding plate 2 can be set to be less than 50% of the projected area of the access hole 12.
[0061] like Figure 5As shown, when the folding plate 2 is in the unfolded state, the unfolding angle of the folding plate 2 corresponding to the first plate 21 and the second plate 22 is 180°, and both the first plate 21 and the second plate 22 are located inside the access hole 12. At this time, along the projection direction perpendicular to the wall surface where the access hole 12 is located, the total projected area of the first plate 21 and the second plate 22 is less than the projected area of the access hole 12. For example, the total projected area of the first plate 21 and the second plate 22 can be set to 50%-80% of the projected area of the access hole 12.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
