Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, and more specifically, to an integrally formed packaging box with a built-in buffer structure. Background Art

[0002] Packaging boxes can protect products during the product circulation process, prevent the products from being broken during transportation and storage, and also have a certain function of appearance display. Among them, paper packaging boxes are widely used due to their low cost, easy processing, and light weight.

[0003] However, most paper packaging boxes do not have a buffer structure. When packaging fragile products or high-end products, an additional independent lining structure needs to be placed. This not only increases the management cost due to the increase in the types of packaging materials, but also leads to an increase in the consumption of raw materials and costs.

[0004] The packaging box with a built-in buffer structure provided by the utility model patent CN219258000U has side buffer parts and an upper buffer part integrally arranged inside the packaging box. However, between the side buffer plates and the connecting pieces of the side buffer parts is a cutting line, and sharp ridge lines will be formed on both sides of the side buffer parts after folding, which are likely to cut the products or product packaging bags; the side buffer parts do not have other support structures, resulting in unstable structures themselves. With the impact of the products during transportation bumps, the side buffer parts are easily deformed and damaged, thus losing the function of fixing the products and buffering protection, leading to an increased risk of poor product appearance.

[0005] In summary, how to reduce the risk of damage to products caused by packaging boxes with built-in buffer structures is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

[0006] In view of this, the purpose of the utility model is to provide an integrally formed packaging box with a built-in buffer structure. The buffer parts are all formed by folding, with simple structures and high folding efficiency. Moreover, the buffer parts have no sharp cross-sections or ridge lines, avoiding cutting or scratching the products or product packaging bags, and significantly reducing the risk of poor product appearance.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An integrally formed packaging box with a built-in buffer structure includes a box body structure surrounded by a front panel, a rear panel, a bottom panel, and two side panels. On one side of each of the two side panels relatively far from the bottom panel, a side buffer plate is connected.

[0009] One side of the front panel relatively far from the bottom panel is connected with a bottom buffer plate, and the bottom buffer plate can be folded into a concave-shaped structure inside the box body structure to form a front buffer part for abutting against the front panel, a bottom buffer part for abutting against the bottom panel, and a rear buffer part for abutting against the rear panel.

[0010] Preferably, the side buffer part includes a Z-shaped structure or a C-shaped structure.

The outer edge of the side bottom panel is provided with a tongue, and a jack for inserting the tongue is provided at the connection between the side panel and the bottom panel.

[0013] Preferably, the bottom buffer plate includes a front top panel, a front inner connecting plate, a bottom connecting plate, a rear inner connecting plate, a rear top panel, and a rear tongue plate. After folding, the front top panel, the bottom connecting plate, and the rear top panel are all parallel to the bottom panel, the front inner connecting plate is parallel to the front panel, and the rear inner connecting plate is parallel to the rear panel.

[0014] Preferably, the rear tongue plate is arranged at the outer edge of the rear top panel, and a jack for inserting the rear tongue plate is provided at the connection between the rear panel and the top cover.

[0015] Preferably, the rear tongue plate is used to support the rear top panel. After folding, the rear tongue plate is tightly arranged against the inner side surface of the rear panel.

[0016] Preferably, the bottom panel is formed by the interpenetrating folding of a front panel bottom plate, a rear panel bottom plate, and side panel bottom plates on both sides.

[0017] Preferably, a tongue is provided at the connection between the bottom buffer plate and the front panel, and a socket for inserting the tongue is provided on the top cover or vice versa.

[0018] When the integrally formed packaging box with a built-in buffer structure provided by the present utility model is folded, first, the bottom plates of the front panel, the rear panel, and the side panels on both sides are interpenetrated and folded to form a bottom panel, so that the front panel, the rear panel, the bottom panel, and the side panels on both sides enclose a box structure; the side buffer plates connected to the side panels on both sides are folded towards the inside of the box structure, so that the side buffer plates are folded into a Z-shaped structure or a C-shaped structure to form two side buffer parts for abutting against the side panels; the bottom buffer plate connected to the front panel is folded towards the inside of the box structure, so that the bottom buffer plate forms a concave-shaped structure, thereby forming a front buffer part for abutting against the front panel, a bottom buffer part for abutting against the bottom panel, and a rear buffer part for abutting against the rear panel; finally, the top cover and the box structure are connected through a tongue structure, a buckle structure, etc.

[0019] It should be noted that the folding sequence of the side buffer plates and the bottom buffer plates is not limited and should be reasonably selected according to the actual situation.

[0020] Therefore, for the integrally formed packaging box with a built-in buffer structure provided by the present utility model, the buffer parts are all formed only by folding without cutting.

Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] The core of the present invention is to provide an integrally formed packaging box with a self - contained buffer structure. The buffer parts are all formed by folding, with a simple structure and high folding efficiency. Moreover, the buffer parts have no sharp cross - sections or edges, avoiding cutting or scratching the product or the product packaging bag, and significantly reducing the risk of poor product appearance.

[0032] The integrally formed packaging box with a self - contained buffer structure provided by the present invention includes a box body structure surrounded by a front panel 10, a rear panel 30, a bottom panel 40 and two side panels 20. On the side of each of the two side panels 20 relatively far from the bottom panel 40, a side buffer plate 60 is connected. The side buffer plate 60 can be folded towards the inside of the box body structure to form a side buffer part for abutting against the side panel 20.

[0033] On the side of the front panel 10 relatively far from the bottom panel 40, a bottom buffer plate 70 is connected. The bottom buffer plate 70 can be folded towards the inside of the box body structure to form a concave - shaped structure, so as to form a front buffer part for abutting against the front panel 10, a bottom buffer part for abutting against the bottom panel 40, and a rear buffer part for abutting against the rear panel 30.

[0034] Please refer to Figure 3 , the integrally formed packaging box includes a front panel 10, a rear panel 30 and two side panels 20 on both sides. At least one of the front panel 10, the rear panel 30 or the side panel 20 is provided with an adhesive panel 80, so that the front panel 10, the side panel 20 and the rear panel 30 are sequentially connected and formed.

[0035] The bottom of the front panel 10 extends to be provided with a front panel bottom plate 41, the bottom of the side panel 20 extends to be provided with a side panel bottom plate 42, and the bottom of the rear panel 30 extends to be provided with a rear panel bottom plate 43. The three can be formed into a bottom panel 40 through interspersed folding.

[0036] The front panel 10, the side panel 20, the rear panel 30, and the bottom panel 40 can enclose a box structure. The top of the rear panel 30 extends to be provided with a top cover 50. The top cover 50 and the box structure can be connected by an adhesive method, or can also be connected by a tongue structure, a buckle structure, etc.

[0037] Please refer to Figure 1 , at the connection between the bottom buffer plate 70 and the front panel 10, one of the top cover 50 is provided with a tongue 91, and the other is provided with a socket 92 for inserting the tongue 91; the specific shapes of the tongue 91 and the socket 92 are not limited, as long as the two can be snap-connected.

[0038] The specific materials, shapes, dimensions, distributions, etc. of the front panel 10, the side panel 20, the rear panel 30, the bottom panel 40, the top cover 50, and the bonding panel 80 are determined with reference to the prior art according to the actual production needs, and will not be elaborated here.

[0039] In order to prevent the product from frequently colliding with the packaging box during transportation, resulting in damage to the product or the product packaging bag, the packaging box is provided with a front buffer part for abutting against the front panel 10, a side buffer part for abutting against the side panel 20, a bottom buffer part for abutting against the bottom panel 40, and a rear buffer part for abutting against the rear panel 30.

[0040] Among them, the side buffer part is formed by folding the side buffer plate 60. The side buffer plate 60 is arranged at the top of the side panel 20 relatively far from the bottom panel 40. After the box structure is folded, the side buffer plate 60 is folded into the box structure to form a Z-shaped structure or a C-shaped structure, which is the side buffer part;

[0041] The front buffer part and the rear buffer part are formed by folding the bottom buffer plate 70. The bottom buffer plate 70 is arranged at the top of the front panel 10 relatively far from the bottom panel 40. After the box structure is folded, the bottom buffer plate 70 is folded into the box structure to form a concave-shaped structure. The two sides of the concave-shaped structure are respectively abutted against the front panel 10 and the rear panel 30 to form the front buffer part and the rear buffer part, and the middle part of the concave-shaped structure is abutted against the bottom panel 40 to form the bottom buffer part.

[0042] The widths of the side buffer parts on both sides can be the same or different. Similarly, the widths of the front buffer part and the rear buffer part can be the same or different; the specific widths of the side buffer part, the front buffer part, and the rear buffer part usually need to be determined according to the materials and design costs of the integrally formed packaging box in actual production, etc., and the folding difficulty and the stability of each buffer part are comprehensively considered.

[0043] To save transportation space, the one-piece formed packaging box is usually transported in a folded flat form rather than in the form of a three-dimensional packaging box after folding.

[0044] When folding, first interweave and fold the front panel bottom plate 41, the rear panel bottom plate 43 and the side panel bottom plates 42 on both sides to form the bottom panel 40, so that the front panel 10, the rear panel 30, the bottom panel 40 and the two side panels 20 enclose a box body structure; fold the side buffer plates 60 connected to the two side panels 20 inwardly into the box body structure, so that the side buffer plates 60 are folded into a Z-shaped structure or a C-shaped structure to form two side buffer parts for abutting against the side panels 20; fold the bottom buffer plate 70 connected to the front panel 10 inwardly into the box body structure, so that the bottom buffer plate 70 forms a concave-shaped structure, thereby forming a front buffer part for abutting against the front panel 10, a bottom buffer part for abutting against the bottom panel 40 and a rear buffer part for abutting against the rear panel 30; finally, connect the top cover 50 and the box body structure through a tongue structure, a snap structure, etc.

[0045] It should be noted that the folding order of the side buffer plate and the bottom buffer plate is not limited and should be reasonably selected according to the actual situation.

[0046] In this embodiment, for the one-piece formed packaging box with a self-buffer structure, the buffer parts are all formed only by folding without cutting. The buffer parts formed after folding have no sharp cross-sections or edges, avoiding the buffer part structure from scratching the product or the product packaging bag, and significantly reducing the risk of poor product appearance; the structure is simple, can be integrally formed by folding, and has few forming actions required for folding, is simple and efficient, and is conducive to saving labor.

[0047] On the basis of the above embodiment, the side buffer plate 60 includes a side top panel 61, an inner connecting plate 62 and a side bottom panel 63. After folding, both the side top panel 61 and the side bottom panel 63 are parallel to the bottom panel 40, and the inner connecting plate 62 is parallel to the side panel 20.

[0048] It should be noted that since the packaging box paper used for folding and forming the packaging box itself has a certain thickness, in order to make the side bottom panel 63 closely fit with the bottom panel 40, the height of the inner connecting plate 62 is slightly less than the height of the side panel 20.

[0049] When the side buffer plate 60 is folded into a C-shaped structure inwardly into the box body, the side top panel 61 and the side bottom panel 63 are on the same side of the inner connecting plate 62. To effectively fix the side stabilizing part, preferably, the outer edge of the side bottom panel 63 is provided with a tongue, and the connection between the side panel 20 and the bottom panel 40 is provided with a jack for inserting the tongue. Of course, the tongue structure can also be replaced with a snap structure;

[0050] When the side buffer plate 60 is folded into a Z-shaped structure into the box body, the bottom connecting plate 73 of the bottom buffer plate 70 is overlapped on the top of the side bottom panel 63 to fix the side bottom panel 63, thereby effectively fixing the side buffer part. Compared with folding into a C-shaped structure, folding the side buffer plate 60 into a Z-shaped structure can not only eliminate fragmentary connecting structures such as tongues and simplify the structure of the packaging box, but also enable the side bottom panel 63 to form a reinforced buffer structure under the two sides of the bottom buffer part formed by folding the bottom buffer plate 70, which is more conducive to reducing folding and forming actions and further saving labor.

[0051] On the basis of the above embodiment, the bottom buffer plate 70 includes a front top panel 71, a front inner connecting plate 72, a bottom connecting plate 73, a rear inner connecting plate 74, a rear top panel 75 and a rear tongue plate 76. After folding, the front top panel 71, the bottom connecting plate 73 and the rear top panel 75 are all parallel to the bottom panel 40, the front inner connecting plate 72 is parallel to the front panel 10, and the rear inner connecting plate 74 is parallel to the rear panel 30.

[0052] The bottom connecting plate 73 may be disposed above the side bottom panel 63 . In this case, the bottom buffer portion is overlapped above the side bottom panel 63 . The side bottom panel 63 may further enhance the buffering effect on both sides of the bottom buffer portion.

[0053] Of course, the bottom connecting plate 73 may also be disposed below the side bottom panel 63 , and in this case, the side buffer portion is overlapped on the bottom connecting plate 73 .

[0054] In addition, the bottom connecting plate 73 can also be arranged in parallel with the side bottom panel 63. At this time, the side buffer portion is a C-shaped structure, the side surface of the bottom connecting plate 73 abuts against the inner connecting plate 62, and the bottom connecting plate 73 and the side bottom panel 63 have no crimping relationship.

[0055] Assume that the length, width and height of the inner dimensions of the box structure after folding are a, b and h respectively, that is, the distance between the inner surfaces of the two side panels 20 of the box structure is a, the distance between the inner surfaces of the front and rear panels of the box structure is b, and the distance between the inner surface of the bottom panel 40 of the box structure and the inner surface of the top cover 50 is h;

[0056] If the widths of the buffer parts on both sides are t1 and t2 respectively, when the front top panel 71 and the rear top panel 75 are overlapped on the side top panels 61 of the side buffer parts on both sides, the lengths a1 of the front top panel 71 and the rear top panel 75 both satisfy a≥a1>a-t1-t2, and a1=a is usually set so that the front top panel 71 and the rear top panel 75 are overlapped on the side top panels 61 of the side buffer parts on both sides, thereby limiting the side buffer parts;

[0057] When both of the two side buffer parts are Z-shaped structures, or when the two side buffer parts only abut against the side surface of the bottom connecting plate 73, the lengths a2 of the front inner connecting plate 72, the bottom connecting plate 73 and the rear inner connecting plate 74 all satisfy a2 ≤ a - t1 - t2, so as to facilitate the folding and forming of the front buffer part, the rear buffer part and the bottom buffer part.

[0058] In order to make the concave structure formed by folding the bottom buffer plate 70 stable, a rear inserting tongue plate 76 can be provided at the outer edge of the rear top panel 75 relatively far from the front panel 10, and a jack can be provided at the connection between the rear panel 30 and the top cover 50, and the rear inserting tongue plate 76 is inserted into the above jack.

[0059] The rear inserting tongue plate 76 can also be folded inwards. After folding, the rear inserting tongue plate 76 is arranged close to the inner side surface of the rear panel 30, so as to effectively support the rear top panel 75.

[0060] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

[0061] The integrated packaging box with a built-in buffer structure provided by the present utility model has been introduced in detail above. Specific examples are used herein to illustrate the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model.
