BACKGROUND
The packing box is usually used to package objects. When these boxes are transported, vibrations and bumps can easily happen that will cause damage to objects. The packing boxes usually have poor buffer capacity, and effective protection of the objects is hardly to get during transportation. To improve the buffer effect, more additional buffer materials, such as foam, bubble paper, sponge, paper holder, and etc., are usually filled or set in the box. As a result, not only the cost but also the complexity of the packaging increases.

DETAILED DESCRIPTION
Here, examples of the present disclosure will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same reference numbers in different drawings indicate the same or similar elements. The examples described following do not represent all examples consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the disclosure as detailed in the appended claims.
It should be noted that in this application, the terms “include”, “comprise” or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, product or device including a series of elements not only those listed, but also those that are not explicitly listed, or elements inherent to the process, method, product, or device. Without more restrictions, the element defined by the sentence “including a . . . ” does not exclude the existence of other identical elements in the process, method, product or device that includes the element. In addition, components, features, and elements with the same name in different examples of this disclosure may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation or further combined with the context in the specific example.
It should be understood that although the terms first, second, or third, etc. may be used herein to describe various information, and the information should not be limited to these terms. These terms are merely used to distinguish the same type of information from each other. For example, without departing from the scope of this disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word “if” as used herein can be interpreted as “when” or “while” or “in response to determination”. Furthermore, as used in this disclosure, the singular forms “a”, “an” and “the” are also intended to include the plural forms, unless the context indicates to the contrary. It should be further understood that the terms “comprising” and “including” indicate the presence of the described features, steps, operations, elements, components, items, types, and/or groups, but do not exclude the existence, appearance or addition of one or more other features, steps, operations, elements, components, items, types, and/or groups. The terms “or” and “and/or” used in this disclosure are interpreted as inclusive or mean any one or any combination. Therefore, “A, B or C” or “A, B and/or C” means “any of the following: A; B; C; A and B; A and C; B and C; A, B and C”. An exception to this definition will only occur when the combination of elements, functions, steps or operations is inherently mutually exclusive in some way. In describing the structure of a component, when a layer or an area is referred to as being “on” or “above” another layer or area, it can mean that it is directly on another layer or area, or mean that there are other layers or areas between them. And, if the component is turned over, the layer or area will be “below” or “under” another layer or area. In the example of the present disclosure, “B corresponding to A” means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean that B is determined only according to A, and B can also be determined according to A and/or other information.
It should be understood that the specific examples described here are merely used to explain the present disclosure, and are not intended to limit the present disclosure.
In the following description, the use of suffixes about element, such as “module”, “part” and “unit” are merely used to describe and best understand this disclosure, and have no specific meaning in itself. Therefore, “module”, “part” or “unit” can be used in a mixed manner.
The packing boxes are usually used to package objects. When these boxes are transported, vibrations and bumps can easily happen that will cause damage to objects. The packing boxes in the prior art are usually formed by bending a single well-cut cardboard, for example, a cuboid packing box. Because all the six sides only have a cardboard of single layer or double layers, the buffer capacity of the box is poor, and it's hardly to protect the objects effectively during transportation. In order to improve the buffer effect, more additional buffer materials, such as foam, bubble paper, sponge, paper holder, and etc., are usually filled or set in the box. When making boxes, additional buffer materials increase the cost of the box. In addition, when packing objects, first it is necessary to bend and fix the linear box, then to add buffer materials, and finally to fix the objects with buffer materials. This is a complicated process. When opening the boxes, the buffer material must be taken out first, and then the objects can be taken out. This greatly affects the user's experience and feelings.
To resolve the foregoing technical problems, this disclosure provides a packing box and a cardboard structure. A carrying structure with a deformable buffer part is arranged in the packing box. With the deformable the buffer part can buffer objects by absorbing external vibrations. In addition, the carrying structure and the side wall of the packing box are a bendable one-piece structure, so that when the packing box is made, the carrying structure can be directly obtained by bending, and the carrying structure can be bent into the interior of the packing box, thereby the process of adding buffer materials can be omitted, the production cost of the packing box is reduced, and the packaging process of the packing box is simplified.
The First Example
FIG. 1 is the schematic diagram of the packing box according to the first example of the present disclosure when it is closed. FIG. 2 is the schematic diagram of the packing box according to the first example of the present disclosure when it is opened and no object has been put in it. FIG. 3 is the schematic diagram of the packing box according to the first example when it is expanded.
With reference to FIGS. 1 and 2, the packing box of the example in the present disclosure includes: a box body, which further comprises of a bottom 1, a side wall 2 and a containing space; the side wall 2 connects to the bottom 1 and the containing space is formed by the bottom 1 and the side wall 2; a carrying structure 3, positioned in the containing space, and the carrying structure 3 is connected to the side wall 2 with a bendable connection; the carrying structure 3 includes the connecting part 31 and the buffer part 32; wherein the buffer part 32 is connected to both ends of the connecting part 31 along the second direction B; the carrying structure 3 is connected with the side wall 2 through the connecting part 31; the buffer part 32 is a structural component that is connected to the connecting part with a bendable connection, and the buffer part 32 abuts against the side wall 2 with a amount of deformation; the effective space inside the box changes with the deformation of the buffer part 32.
The shape of the box body is not limited, for example, it may be cylindrical, triangular prism, cuboid, or oblique parallelepiped. For the convenience of description, referring to FIGS. 1 to 3, the example of the present disclosure takes cuboid for example. When the packing box is placed on a horizontal surface, the three edges of one vertex of the cuboid structure respectively correspond to three directions, namely, the directions of the length, width, and height of the cuboid structure. Exemplarily, as shown in FIGS. 1 and 3, the first direction A is parallel to the horizontal plane, the second direction B is parallel to the horizontal plane, the first direction A and the second direction B are perpendicular, and the third direction C is perpendicular to the horizontal plane. The side wall 2 includes a side wall body which comprises of a first wall 201, a second wall 202, a third wall 203 and a fourth wall 204. The first wall 201 and the third wall 203 are a set of opposite wall surfaces in the first direction A. The second wall 202 and the fourth wall 204 are a set of opposite wall surfaces in the second direction B. Both the second wall 202 and the fourth wall 204 are connected to the bottom 1 with a bendable connection, so that the bottom 1 will not be easily opened under the gravity action of the objects that are put inside the box. Both the first wall 201 and the third wall 203 are connected to the second wall 202 or the fourth wall 204 with a bendable connection, so that the bottom 1 and the side wall 2 form a bendable one-piece structure. For easy to cut, both the first wall 201 and the third wall 203 can be connected to the fourth wall 204 with a bendable connection.
In an alternative example, referring to FIG. 2, the bottom 1 and the side wall 2 of the box body form a containing space, and the containing space can contain objects. The bottom 1 and the side wall 2 can be two separate parts, or can be a bendable one-piece structure. Optionally, the bottom 1 and the side wall 2 are a bendable one-piece structure, so that the box body of the packing box can be obtained by bending the entire cardboard that has been well cut. That is to say, when the box body is cuboid, the bottom 1 and the side wall 2 of the box body are a bendable one-piece structure, and the bottom 1 and the side wall 2 are obtained by bending cardboard that has been well cut.
In an alternative example, the carrying structure 3 is put in the containing space of the box body, and is mainly used to hold objects and meanwhile to buffer the objects. Since the carrying structure 3 and the side wall 2 are also a bendable one-piece structure, they can be obtained by a well-cut cardboard at the same time. Exemplarily, the carrying structure 3 is connected to one end of at least one of the first wall 201 or the third wall 203 in the third direction C with a bendable connection. When bending, it can be bent toward the inside of the box body so that the carrying structure 3 is positioned inside the box body.
In an alternative example, referring to FIGS. 2 and 3, the side wall 2 further includes a fixing part 21 and a side wall body; the fixing part 21 is respectively connected to the two ends of the side wall body along the first direction A with a bendable connection; the fixing part 21 is permanently connected to the side wall body. The fixing part 21 can fix the side wall 2 as a whole to form the columnar side surface of the box. Exemplarily, the fixing part 21 is connected to the second wall 202 along the two ends of the side wall body in the first direction A with a bendable connection, and is permanently connected to the inner side of the first wall 201 and the inner side of the third wall 203, so that the side wall 2 forms a complete and solid columnar side. Wherein the fixing part 21 and the side wall 2 can be fixed by sticking.
In an alternative example, the side wall 2 further includes an extension part 22; the extension part 22 is connected to the fixing part 21 with a bendable connection, and at least a part of the bottom 1 is attached to the extension part 22. The extension part 22 can increase the connection performance between the side wall 2 and the bottom 1. Exemplarily, the extension part 22 extends to the inner side of the bottom 1 along the first direction A, and it can block the gap not only between the first wall 201 and the bottom 1 but also between the third wall 203 and the bottom 1.
FIG. 4 is the sectional view of the D-D section of the packing box according to the first example of the present disclosure in FIG. 2 when it is opened and no objects have been put in it. FIG. 5 is the sectional view of the D-D section of the packing box according to the first example of the present disclosure in FIG. 2 when it is opened and objects have been put in it. FIG. 6 is the sectional view of the D-D section of the packing box according to the first example of the present disclosure in FIG. 2 when it is closed and objects have been put in it.
In an alternative example, referring to FIGS. 4 to 6, connecting part is used for connecting the carrying structure 3 and the side wall 2. The buffer part 32 is connected to the two ends of the connecting structure along the second direction B with a bendable connection, and abuts against the side wall 2. When objects are put in the box, the buffer part 32 is positioned between both sides of the object along the second direction B and the side wall 2, so that the buffer part 32 can buffer the objects along the second direction B. Since the buffer part 32 is connected to the connecting part with a bendable connection, the buffer part 32 and the connecting part can also be obtained by bending a well-cut cardboard. In addition, the buffer part 32 is a structure with a deformation amount. When the box body vibrates, the deformable buffer part 32 can absorb the vibration, thereby it has a good buffer effect. It should be noted that at least parts of the connecting part are in contact with the side wall 2 of the object, so that the connecting part can not only position but also buffer the object along the first direction A.
In an alternative example, continuing to refer to FIGS. 4 to 6 along with FIG. 3, the carrying structure 3 further includes a carrying part 33, and the carrying part 33 is connected to a side of the connecting part close to the bottom 1 with a bendable connection, and the carrying part 33 abuts against the bottom 1. The carrying part 33 serves as a main structure for carrying the object. When objects are put in the box, the carrying part 33 supports the objects. The carrying part 33 and the connecting part 31 are one-piece structure that can be bent. Therefore, the carrying part 33 and the connecting part 31 are obtained by bending a well-cut cardboard. In addition, the carrying part 33 can not only carry but also buffer the object along the third direction C.
In an alternative example, referring to FIGS. 4 to 6, the carrying part 33 is an elastic bending structure. The elastic bending structure includes a first bending plate 331 and a second bending plate 332. One end of the first bending plate 331 is connected to the connecting part with a bendable connection. And the other end of the first bending is connected to the second bending plate 332 with a bendable connection. The carrying part 33 is similar to the buffer part 32 with a deformation amount too. Since the elastic bending structure of the carrying part 33 has a certain resilience capability, the carrying part 33 can not only carry but also buffer the object along the third direction C. In addition, when the packing box is opened, the restriction from above is released. Under the rebound action of the elastic bending structure, the object will be lifted from the inside of the box by the carrying part 33. In this way, when the packing box is opened, the rebound effect of automatically raising objects is obtained, which enhances the user's experience and feelings.
In an alternative example, referring to FIGS. 4 to 6 along with FIG. 3, the length of the fold line between the first bending plate 331 and the connecting part is less than that between the first bending plate 331 and the second bending plate 332; the bending angle between the first bending plate 331 and the second bending plate 332 is greater than 90° and less than 180°. The bending angle of the first bending plate 331 and the second bending plate 332 are obtuse angle. So, an acute angle is formed, thus the elastic bending structure of the carrying part 33 has good resilience, therefore the carrying part 33 can have a certain buffer ability. Moreover, the main function of the carrying part 33 is to support objects. So, making the length of the fold line between the first bending plate 321 and the connecting part is shorter than that between the first bending plate 331 and the second bending plate 332, which can make the second bending plate 332 provide a more sufficient supporting effect for the carrying part 33. Since the length of the fold line between the first bending plate 331 and the connecting part 31 is smaller than the length of the fold line between the first bending plate 331 and the second bending plate 332, the area of the second bending plate 332 is larger than that of the first bending plate 331. When the carrying part 33 carries objects, the second bending plate 332 can distribute the weight on the bottom 1. When the carrying part 33 lifts the object, the second bending plate 332 can provide a greater resilience force.
In an alternative example, referring to FIGS. 4 to 6, the buffer part 32 is a buffer bending structure. The buffer bending structure includes a third bending plate 321 and a fourth bending plate 322. The one end of the third bending plate 321 is connected with the connecting part 31 with a bendable connection, the other end of the third bending plate 321 is connected with the fourth bending plate 322 with a bendable connection, and the other end of the fourth bending plate 322 abuts against the side wall 2. The third bending plate 321 and the fourth bending plate 322 form a bending buffer structure with a deformation amount. Since the buffer bending structure has a certain resilience ability, the buffer part 32 can buffer the object along the second direction B. When the object is put in the box, both sides of the object along the second direction B contact with the third bending plate 321. Therefore, the buffer structure can also position the object in the box.
In an alternative example, referring to FIGS. 4 to 6 along with FIG. 3, the length of the fold line between the third bending plate 321 and the fourth bending plate 322 is less than the length of the side line of the fourth bending plate 322 away from the third bending plate 321. The bending angle between the third bending plate 321 and the fourth bending plate 322 is greater than 90° and less than 180°. The bending angle of the third bending plate 321 and the fourth bending plate 322 are obtuse angle. So, an acute angle is formed, thus the elastic bending structure of the buffer part 32 has good resilience, therefore the buffer part 32 can have a good buffer ability. Moreover, since the length of the fold line between the third bending plate 321 and the fourth bending plate 322 is less than the length of the side line of the fourth bending plate 322 away from the third bending plate 321, the area of the third bending plate 321 is smaller than that of the fourth bending plate 322. When objects are put into the box, both the buffer part 32 and the carrying part 33 are positioned between the object and the side wall 2 of the box. For supporting the objects, the first bending plate 331 of the carrying part 33 has a bigger area, so reducing the area of the third bending plate 321 can prevent bending interference between the buffer part 32 and the carrying part 33. Since the main function of the buffer part 32 is buffer, even if the area of the third bending plate 321 is smaller than the area of the fourth bending plate 332, the buffer capacity of the buffer part 32 will not be significantly affected.
In an alternative example, referring to FIGS. 4 to 6 along with FIG. 3, the box body also includes a top cover 4, which is respectively connected to the two ends of the side wall 2 along the second direction B with a bendable connection. The connecting part is a connectable bending structure, the connectable bending structure includes a connecting plate 311, a fifth bending plate 312 and a sixth bending plate 313 that are sequentially connected together with a bendable connection; the buffer part 32 is connected to the connecting plate 311 with a bendable connection; the sixth bending plate 313 is connected to the side wall 2 with a bendable connection; the length of the fold line between the fifth bending plate 312 and the connecting plate 311 is smaller than that between the fifth bending plate 312 and the sixth bending plate 313. The top cover 4 can be separated from the side wall 2, or can be a bendable one-piece structure with the side wall 2. In the example of the present disclosure, the top cover 4 and the side wall 2 are a bendable one-piece structure as an example for description. In order to improve the protection ability of the top cover 4 for the inside of the box, two top covers 4 can be provided, which are respectively connected to the two ends of the side wall 2 along the second direction B by bending together, that is, connected to the second wall 202 and the fourth wall 204 of the box body with a bendable connection (for example, respectively connected to a top edge of the second wall 202 and the fourth wall 204 of the box body along a third direction C with a bendable connection). Therefore, the top cover 4 of the box body can be obtained through the well-cut cardboard. The connectable bending structure of the connecting part also adopts a bending form, which is similar to the carrying part 33. Since the connection part 31 does not need a carrying function, the connecting part 31 realizes the buffer function through the connectable bending structure. The structure of the connectable bending structure and the elastic bending structure may be the same so that the cardboard can be cut easily.
Along the first direction A, two buffer parts 32 can buffer the object. Along the three directions, the carrying part 33 and the connecting part 31 can buffer the object. In addition, the carrying part 33 can also carry and lift the object. Along the second direction B, since the carrying part 33, the connecting part 31 and the buffer part 32 all adopt a deformable bending structure, the area of the connecting part in contact with the object can buffer the object.

The cardboard structure can be bent to form the packing box of the foregoing example of the present disclosure.
Referring to FIG. 7, when the cardboard structure is not bent, the cardboard structure can be regarded as a plane structure, and the two sides of the plane structure are the first surface and the second surface respectively. It should be noted that when the cardboard structure is bent, bending toward the first surface means that the first surface of the two face-to-face bending parts forms an angle less than 180°, and the second surface forms an angle greater than 180°. Correspondingly, bending toward the second surface, which means that the second surface of the two face-to-face bending parts forms an angle less than 180°, and the first surface forms an angle greater than 180°. The box body area S0 can be obtained by bending, and the shape of the box body is not limited. For the convenience of description, the box body is cuboid as an example. The plane of the cardboard structure defines a first reference direction X and a second reference direction Y that cross each other. The fold lines of the bending cardboard structure are parallel to/coincide with the first reference direction X or the second reference direction Y. Since a box of cuboid is taken as an example for description, the first reference direction X and the second reference direction Y are perpendicular to each other.

The second subarea S202 and the fourth subarea S204 are both connected to the bottom area 51. The first subarea S201 and the third subarea S203 are respectively connected to both ends of the fourth subarea S204 along the second reference direction Y. After the first subarea S201, the second subarea S202, the third subarea S203, and the fourth subarea S204 are bent, the side wall body of the side wall 2 is formed.
In an alternative example, referring to FIGS. 8 and 9, the side wall area S2 also includes at least two fixing areas S21. At least two fixing areas S21 are respectively connected to the two ends of the second subarea S202 along the second reference direction Y. The fixing area S21 is bent toward the first surface to form a fixing part 21, and the second surface of the fixing part 21 is permanently connected to the first surface of the side wall body. Exemplarily, it can be fixed by pasting.

In an alternative example, referring to FIG. 10, the carrying area S3 is bent toward the first surface, so that the carrying structure 3 which is formed by bending the carrying area S3 is positioned in the containing space. The connecting subarea S31 itself and the buffer subarea S32 itself may be respectively bent at least once, and each bending may be bent in the direction of the first surface or of the second surface. The connecting subarea S31 is bent to form a connecting part 31, and the buffer subarea S32 is bent to form a buffer part 32.
