[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0030] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0031] At present, the size of the pickup opening of a packaging box is generally fixed. The inventors of the present application have found that when the items loaded in the packaging box are flush with or lower than the pickup opening of the packaging box, it is difficult for users to take out the items from the packaging box, affecting the user experience.

[0032] In order to solve the problems in the prior art, the embodiment of the present application provides a packaging box with an adjustable opening, which is described in detail below in conjunction with the accompanying drawings.

[0033] Figure 1 A schematic diagram of a packaging box with an adjustable opening provided in some embodiments of the present application;

[0034] Figure 2 A schematic diagram of a packaging box with an adjustable opening in an open state provided in some embodiments of the present application; Figure 3 A schematic diagram of an exploded structure of a packaging box with an adjustable opening provided in some embodiments of the present application; Figure 4 A schematic diagram of the unfolded structure of the first wall provided in some embodiments of the present application; Figure 5 A schematic diagram of the unfolded structure of the second wall provided in some embodiments of the present application.

[0035] See also Figures 1 to 5 The embodiment of the present application provides a packaging box with an adjustable opening, including a box bottom component 1 and a side wall component 2, the side wall component 2 and the box bottom component 1 are enclosed to form a main accommodating portion facing a first direction X, the side wall component 2 includes a first wall 21 and a second wall 22, the first wall is provided with a second wall on both sides of the second direction Y, the first wall has a movable portion that can rotate around an axis parallel to the second direction Y in an area away from the box bottom component 1 along the first direction X, the movable portion has side wing plates 214 on both sides of the second direction Y, one of the side wing plates 214 and the second wall is provided with an interlayer, and the other is inserted into the interlayer by interference fit, and the first direction X is perpendicular to the second direction Y.

[0036] When the movable part rotates to the extreme position close to the second wall, the main container part's access opening away from the bottom assembly 1 is relatively small, which can reduce the risk of shaking of items in the packaging box during transportation, and the overall volume of the packaging box is relatively small, which is further convenient for transportation and storage; when the movable part rotates to a position away from the second wall, the main container part's access opening away from the bottom assembly 1 is relatively large, which is convenient for users to take out items from the main container part or place items in the main container part, providing a better user experience. In addition, since the interlayer and the other one mentioned above adopt an interference fit, in the process of rotating the movable part to a position away from the second wall by external force, due to the relatively large friction resistance between the interlayer and the other one mentioned above, after the external force is removed, the movable part can stay in the corresponding position relatively stably. It can be seen that the user can adjust the rotation angle of the movable part according to needs to adjust the size of the access opening according to needs, which is convenient to operate.

[0037] In some embodiments, the interlayer is provided with a first limiting portion at a position away from the bottom assembly 1 along the first direction X, and when the movable part rotates to the extreme position away from the second wall, the other one abuts against the first limiting portion; and / or, the interlayer is provided with a second limiting portion at a position away from the other one along the third direction Z, and when the movable part rotates to the extreme position away from the second wall, the other one abuts against the second limiting portion, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. The first limiting portion can be an independent structure protruding in the interlayer, or it can be a side wall of the interlayer at a position away from the bottom assembly 1 along the first direction X; the first limiting portion can be an independent structure protruding in the interlayer, or it can be a side wall of the interlayer at a position away from the other one along the third direction Z. The first limiting portion and the second limiting portion can achieve the purpose of limiting the extreme position of the movable part away from the second wall by limiting the extreme position of the part of the other one extending into the interlayer, and can improve the overall structural stability.

[0038] Figure 6 A schematic diagram of a packaging box with an adjustable opening provided in some other embodiments of the present application; Figure 7 A schematic structural diagram of a packaging box with an adjustable opening in an open state provided in some other embodiments of the present application.

[0039] like Figures 1 to 7 As shown, in some embodiments, the first wall is arranged on both sides of the second wall along the third direction Z, the interlayer is located on the second wall, and the interlayer is arranged in a one-to-one correspondence with the side wing panels 214 of each first wall, the side wing panels 214 of the first wall are inserted into the corresponding interlayer, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. That is to say, in the packaging box with an adjustable opening in this embodiment, the opening size can be adjusted on both sides of the third direction Z, which can further facilitate the user to take out items from the main containing part or place items in the main containing part, so as to achieve a better user experience.

[0040] like Figures 1 to 5 As shown, in some embodiments, the box bottom assembly 1 includes a bottom box 11, the bottom box 11 has an auxiliary accommodating portion facing the first direction X, the first wall has a fixed portion at a position close to the bottom box 11 along the first direction X, the movable portion is rotatably connected to the fixed portion, the fixed portion includes a first adhesive plate 218, and the second wall has a second adhesive plate 224 at a position close to the bottom box 11 along the first direction X, the first adhesive plate 218 and the second adhesive plate 224 are both adhered to the auxiliary accommodating portion, and by providing the bottom box 11, the structural strength of the bottom of the packaging box can be improved.

[0041] like Figures 1 to 3 As shown, in some embodiments, the bottom box 11 includes a connected bottom wall 113 and a first enclosure portion, the bottom wall 113 and the first enclosure portion together form an auxiliary accommodating portion, the first enclosure portion includes a first baffle 111 perpendicular to the third direction Z and a second baffle 112 perpendicular to the second direction Y, the first baffle 111 is arranged in a one-to-one correspondence with the first wall, the second baffle 112 is arranged in a one-to-one correspondence with the second wall, the first adhesive plate 218 and the second adhesive plate 224 are both adhered to the bottom wall 113, at least part of the fixing portion abuts against the inner side of the first baffle 111, at least part of the second wall abuts against the inner side of the second baffle 112, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. When the items loaded in the main container are shaken or are too large, and a force is applied to the part of the first wall close to the bottom box 11 away from the main container, the fixed part of the first wall can transfer part of the above force to the first baffle 111, thereby reducing the risk of damage to the first wall; when the items loaded in the main container are shaken or are too large, and a force is applied to the part of the second wall close to the bottom box 11 away from the main container, the second wall can transfer part of the above force to the second baffle 112, thereby reducing the risk of damage to the second wall. It can be seen that by limiting the positional relationship between the fixed part and the first baffle 111, and the positional relationship between the second wall and the second baffle 112, the overall structural stability and strength can be further improved.

[0042] like Figure 3As shown, in some embodiments, the box bottom assembly 1 further includes an inner support 12 located in the auxiliary receiving portion, the inner support is annular as a whole, and has a first inner support surface 121 facing the first baffle 111 and a second inner support surface 122 facing the second baffle 112, the first inner support surface 121 is used to press the fixing portion at the corresponding position against the inner side of the first baffle 111, and the second inner support surface 122 is used to press the second wall at the corresponding position against the inner side of the second baffle 112. By providing the inner support, the contact stability between the first baffle 111 and the fastening portion at the corresponding position, and between the second baffle 112 and the second wall at the corresponding position can be improved, so as to reduce the risk of damage to the first wall and the second wall caused by shaking or excessive volume of the items loaded in the main receiving portion; in addition, the inner support can also improve the stability of the first baffle 111 and the second baffle 112, and reduce the risk of the first baffle 111 and the second baffle 112 being sunken into the auxiliary receiving portion due to external force.

[0043] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the second wall also includes a second folding wing plate 221, a second sandwich plate 222 and a second wall plate 223 which are sequentially abutted along the second direction Y, and a second adhesive plate 224 is connected to a side of any one of the second folding wing plate 221, the second sandwich plate 222 and the second wall plate 223 close to the bottom wall 113. The projection of the second sandwich plate 222 is located in the projection range of the second folding wing plate 221 and the projection range of the second wall plate 223 perpendicular to the second direction Y, so that a sandwich is formed between the second folding wing plate 221 and the second wall plate 223, that is, the sandwich is located in the second wall, and the first wall is plugged into the corresponding sandwich through the side wing plate 214. The structural strength of the second wall can be improved by arranging a multilayer board; by arranging a second sandwich plate 222, the area between the second folding wing plate 221 and the second wall plate 223 close to the corresponding active part can form a structurally stable sandwich, and the overall structure is relatively simple. Specifically, in the present embodiment, the second limiting portion refers to the side wall of the second sandwich plate 222 facing the direction of the corresponding side wing plate 214, that is, when the movable portion rotates to the extreme position away from the second wall, the side wing plate 214 abuts against the side wall of the second sandwich plate 222 facing the direction of the corresponding side wing plate 214, thereby achieving the purpose of limiting the extreme position of the movable portion away from the second wall, improving the overall structural stability, and avoiding the situation where the side wing plate 214 is separated from the corresponding interlayer due to the excessive rotation angle of the movable portion.

[0044] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments, the second folding wing plate 221 and the second wall plate 223 are connected by corresponding folding portions at a position away from the bottom wall 113 along the first direction X, the second adhesive plate 224 and the second wall plate 223 are connected by corresponding folding portions, the side of the second folding wing plate 221 facing away from the second sandwich plate 222 abuts against the corresponding second inner supporting surface 122, and the side of the second wall plate 223 facing away from the second sandwich plate 222 abuts against the corresponding second baffle 112. It can be seen that the second wall except the second sandwich plate 222 can be folded by a piece of cardboard, and the structure is simple. Since the second folding wing plate 221 and the second wall plate 223 are connected by corresponding folding portions at a position away from the bottom wall 113 along the first direction X, the second folding wing plate 221, the second interlayer plate 222 and the second wall plate 223 can be stably pressed against each other without being bonded at the position away from the bottom wall 113 along the first direction X, thereby improving the overall production efficiency; in addition, at a position close to the bottom wall 113 along the first direction X, due to the clamping effect of the second inner supporting surface 122 and the second baffle plate 112, the second folding wing plate 221, the second interlayer plate 222 and the second wall plate 223 can be stably pressed against each other without being bonded, thereby further improving the overall production efficiency. Specifically, in the present embodiment, the first limiting portion refers to the side wall of the corresponding interlayer to which the folded portion of the second folding wing plate 221 and the second wall plate 223 faces, that is, when the movable portion rotates to the extreme position away from the second wall, the side wing plate 214 abuts against the side wall of the corresponding interlayer to which the folded portion of the second folding wing plate 221 and the second wall plate 223 faces, thereby achieving the purpose of limiting the extreme position of the movable portion away from the second wall, improving the overall structural stability, and avoiding the situation where the side wing plate 214 is separated from the corresponding interlayer due to excessive rotation angle of the movable portion.

[0045] like Figures 2 to 4 As shown, in some embodiments, the fixed portion also includes a support plate 217, and the support plate 217 is respectively connected to the first adhesive plate 218 and the movable portion on both sides along the first direction X. Along the first direction X, the height of the support plate 217 is the same as the height of the corresponding first baffle 111. By limiting the height of the support plate 217, the connection position between the support plate 217 and the movable portion is closer to the bottom wall 113. Compared with the connection position between the support plate 217 and the movable portion being at a position farther from the bottom wall 113, when the movable portion rotates by the same angle, the size of the retrieval opening changes more greatly, which makes it easier for users to take out items from the main receiving portion or place items in the main receiving portion.

[0046] like Figures 2 to 4As shown, in some embodiments, the movable portion also includes a first wall panel 213, and the first wall panel 213 is connected to the side wing panels 214 on both sides along the second direction Y through corresponding folding portions, and the first wall panel 213 and the support panel 217, and the support panel 217 and the first adhesive panel 218 are respectively connected through corresponding folding portions. It can be seen that the first wall can be folded from a piece of cardboard, and the structure is simple.

[0047] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the first wall panel 213 is provided with a lifting portion at a position away from the bottom assembly 1. Specifically, the lifting portion can be a handle hole 211 opened in the first wall panel 213, or a lifting rope 212 passed through the first wall panel 213, so as to facilitate users to lift and carry the packaging box.

[0048] like Figures 2 to 4 As shown, in some embodiments, the first wall panel 213 is bonded with a first interlayer panel 216 in an area away from the box bottom assembly 1 relative to the lifting portion, which can improve the structural strength of the corresponding position and reduce the risk of damage to the first wall panel 213 due to concentrated force at the corresponding position of the lifting portion.

[0049] like Figures 2 to 4 As shown, in some embodiments, the first interlayer plate 216 is located on the side of the first wall plate 213 facing the corresponding second wall, and the first interlayer plate 216 is bonded with the first folding wing plate 215 on the side facing away from the first wall plate 213. The first folding wing plate 215 is connected to the first wall plate 213 through the corresponding folding portion at a position away from the box bottom assembly 1 along the first direction X, which can further improve the structural strength of the corresponding position.

[0050] like Figures 1 to 3 As shown, in some embodiments, the packaging box with adjustable opening further includes a top cover 3, the top cover 3 includes a top wall 31 and a second enclosure portion enclosed on one side of the top wall 31, when the top cover 3 is in a state of being buckled to the main receiving portion, the movable portion is located at an extreme position close to the second wall, and the first wall and the second wall are both in contact with the inner side of the second enclosure portion. Specifically, in this embodiment, the first enclosure portion includes a third baffle 32 and a fourth baffle 33, wherein the third baffle 32 is arranged in a one-to-one correspondence with the first wall, and the fourth baffle 33 is arranged in a one-to-one correspondence with the second wall, when the top cover 3 is in a state of being buckled to the main receiving portion, the first wall is in contact with the inner side of the corresponding third baffle 32, and the second wall is in contact with the inner side of the corresponding fourth baffle 33. That is to say, when the top cover 3 is in a state of being buckled to the main receiving portion, the movable portion cannot rotate relative to the second wall, which can prevent the main receiving portion from accidentally enlarging the item removal opening and causing the items carried by the main receiving portion to slip.

[0051] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
