[0027] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0028] Figure 1 1 shows a schematic diagram of the packaging structure according to some embodiments of the present invention, and 2 shows a schematic diagram of the blank after the packaging structure is unfolded according to some embodiments of the present invention. Figure 1 and Figure 2 The packaging structure 100 will be described.

[0029] like Figure 1 As shown, the packaging structure 100 includes a box body 110, a sealing portion 120, and an extension portion 130. The box body 110 defines a storage space that can be used to accommodate contents. In some embodiments, the storage space can be completely enclosed, or partially open or hollowed out to present different visual effects. The shape and size of the storage space can be determined according to the contents. In some embodiments, a filler can be provided in the storage space to fill the gap between the contents and the storage space, reduce the shaking amplitude of the contents in the storage space, and protect the contents.

[0030] In this embodiment, the accommodating space includes a first main surface 111 and a second main surface 112 connected to each other, and in this embodiment, the angle between the first main surface 111 and the second main surface 112 is less than 90°. The first main surface 111 refers to the surface of the box body 110 facing downward ( Figure 1 ), the second main surface 112 is inclined relative to the first main surface 111. Compared to a conventional rectangular parallelepiped, the box body in this embodiment is an inclined surface at the position of the second main surface 112. In some embodiments, the angle between the first main surface 111 and the second main surface 112 is 45°.

[0031] The sealing portion 120 is detachably or destructibly connected to the second main body surface 112. In this embodiment, the sealing portion 120 is used to seal the storage space of the box body 110. When the sealing portion 120 is separated from or destroyed relative to the second main body surface 112, the storage space of the box body 110 is opened. Specifically, a portion of the sealing portion 120 is fixed to the second main body surface 112 by gluing or hot-melting, or the sealing portion 120 and the second main body surface 112 are detachably connected by a structure such as a magnetic attraction member or Velcro.

[0032] The extension portion 130 extends from the inside of the accommodating space to the outside, such as Figure 1 As shown in FIG, the extension portion 130 extends to the outside of the accommodating space at the connection position of the first main surface 111 and the second main surface 112. In some embodiments, a through hole can be provided on the extension portion 130, and the packaging structure 100 can be hung and placed at the position of the through hole. Alternatively, in some embodiments, the back side ( Figure 1 Adhesive may be provided on the side facing downward in the middle so that the packaging structure 100 can be adhered to the facade.

[0033] In this embodiment, the box body 110 is made by folding a first blank 210, and the extension portion 130 is made by folding a second blank 230, wherein the first blank 210 and the second blank 230 are cut from the same sheet 200, wherein the sheet 200 can be a paper material, such as cardboard or gray board. In some embodiments, the sheet 200 is made by folding a first blank 210, and the extension portion 130 is made by folding a second blank 230. Figure 2 As shown, the sheet 200 is cut into a first blank 210 and a second blank 230, and the first blank 210 and the second blank 230 are connected to each other as a whole. The first blank 210 and the second blank 230 are cut from the sheet 200, which can improve the utilization rate of the sheet 200.

[0034] like Figure 2 As shown, the first blank 210 includes a first main body sheet 211 and a side structure sheet 214. The first main body sheet 211 corresponds to the first main surface 111 of the box body 110. That is, after the first blank 210 is folded and formed into the box body 110, the first main body sheet 211 forms the first main surface 111 of the box body 110, which can be the bottom surface of the box body 110.

[0035] The side structural piece 214 and the first main body piece 211 are rotatably connected. During the folding and forming process of the packaging structure 100, the side structural piece 214 rotates and bends relative to the first main body surface 111, folding to form the side wall 114 of the box body 110. In some embodiments, the first main body surface 111 can serve as the bottom surface of the box body 110, and the side structural piece 214 folds into the side wall 114 of the box body 110. The top surface of the box body 110 can be folded from the first blank 210. Alternatively, the top surface of the box body 110 is provided separately and assembled on the top surface after the box body 110 is formed. For example, a transparent or hollow glass sheet, plastic sheet, etc. is affixed to the top surface of the box body 110.

[0036] In this embodiment, the second blank 230 and the first main body sheet 211 are spaced apart from each other. Specifically, in this embodiment, the extension portion 130 and the first main body surface 111 are provided separately, which facilitates distributing the gravity of the packaging structure 100 and the contents. Specifically, the first blank 210 and the second blank 230 are folded so that the extension portion 130 extends outside the accommodating space at the location where the first main body surface 111 and the second main body surface 112 connect.

[0037] The extension portion 130 and the first main surface 111 in this embodiment are separately arranged. When the packaging structure 100 is suspended by the extension portion 130, the gravity of the packaging structure 100 and the contents can be avoided from being concentrated at the junction of the extension portion 130 and the first main surface 111, thereby reducing the risk of the extension portion 130 breaking or the first main surface 111 bulging outward due to tension, which is beneficial to improving the stability of the packaging structure 100 and is suitable for applying paper materials to the packaging structure 100.

[0038] On the other hand, the angle between the first main surface 111 and the second main surface 112 is less than 90°, and at the same time, the extension portion 130 extends from the connection position of the first main surface 111 and the second main surface 112 to the outside of the accommodating space. The force between the extension portion 130 and the box body 110 acts at the connection position of the first main surface 111 and the second main surface 112, and a part of it can be dispersed on the second main surface 112, which can improve the stability of the packaging structure 100.

[0039] In some embodiments, as Figure 1 As shown, a first slot 113 is provided at the connection position between the first main body surface 111 and the second main body surface 112, and the extension portion 130 extends from the position of the first slot 113 to the outside of the accommodating space. Figure 2 As shown, a strip-shaped through hole 213 may be opened at a corresponding position in the first blank 210 , so that the second blank 230 can be folded and pass through the first blank 210 at the position of the strip-shaped through hole 213 to form an extension portion 130 .

[0040] Further, such as Figure 2 As shown, the first blank 210 also includes a second main body sheet 212, wherein the second main body sheet 212 corresponds to the second main surface 112. That is, in this embodiment, the second main body sheet 212 is folded to form the second main surface 112. In this embodiment, the first main body sheet 211 and the second main body sheet 212 are rotatably connected. For example, the second main body sheet 212 can be rotated relative to the first main body sheet 211 around the connection between the two to an angle of less than 90° with the first main body sheet 211, thereby forming the second main surface 112. A strip-shaped through hole 213 is provided at the connection between the first main body sheet 211 and the second main body sheet 212 to facilitate the second blank 230 to pass through the strip-shaped through hole 213 to form the extension portion 130.

[0041] A connecting piece 240 is provided between the second main body piece 212 and the second blank 230. The connecting piece 240 can be bent relative to the second main body piece 212 so that the second blank 230 can extend from the position of the strip-shaped through hole 213 (the first slot 113) to the outside of the accommodating space. Figure 2 As shown in FIG, the connecting piece 240 is oriented relative to the second main body piece 212. Figure 2 As shown in the left side bend, the second blank 230 is close to the first main body piece 211 and passes through the strip-shaped through hole 213.

[0042] In this embodiment, the second main body piece 212 and the connecting piece 240 are separated between the second blank 230 and the first main body piece 211, which is beneficial to improving the stability of the packaging structure 100 and allowing the first blank 210 and the second blank 230 to be cut from the same sheet 200, reducing production difficulty and production costs.

[0043] According to a preferred embodiment of the present invention, Figure 2 As shown, the connecting piece 240 includes a first structural piece 241 and a second structural piece 242. The first structural piece 241 and the second main body piece 212 are rotatably connected, the second structural piece 242 and the first structural piece 241 are rotatably connected, and the second blank 230 and the second structural piece 242 are rotatably connected. The second main body piece 212, the first structural piece 241, the second structural piece 242, and the second blank 230 are all rotated and bent.

[0044] Preferably, the connection position between the first structural piece 241 and the second main body piece 212 , the connection position between the second structural piece 242 and the first structural piece 241 , and the connection position between the second blank 230 and the second structural piece 242 are parallel to each other.

[0045] The angle between the second main surface 112 folded from the second main body sheet 212 and the first main surface 111 folded from the first main body sheet 211 is less than 90°, that is, there is a wedge-shaped cavity between the first main surface 111 and the second main body sheet 112. In this embodiment, the first structural sheet 241 and the second structural sheet 242 can be located in the wedge-shaped cavity between the first main surface 111 and the second main body sheet 112.

[0046] Furthermore, according to a preferred embodiment of the present invention, during the folding process of the packaging structure 100, the first structural piece 241 and the second structural piece 242 rotate relative to the second main body piece 212 toward the first main body piece 211. Figure 2 As shown in FIG, the first structural piece 241 and the second structural piece 242 are rotated to the left relative to the second main body piece 212. In addition, in this embodiment, after the second main body piece 212, the first structural piece 241 and the second structural piece 242 are bent, the second structural piece 242 and the first main body piece 211 are attached to each other, which is beneficial to improving the stability of the packaging structure 100.

[0047] Preferably, the dimensions of the first structural piece 241 and the second structural piece 242 can be set so that the edge position of the second structural piece 242 abuts the connection position of the first main body piece 211 and the second main body piece 212, which can further improve the stability of the packaging structure 100. By utilizing the structural strength of the second structural piece 242, the protruding length of the second blank 230 at the position of the strip through hole 213 is limited, which can reduce the risk of damage to the position of the strip through hole 213 when the gravity of the packaging structure 100 and the contents is large.

[0048] Specifically, according to the preferred embodiment of the present invention, Figure 2 As shown, the size of the second structural piece 242 is larger than the size of the bar-shaped through hole 213 (first slot 113), so that the connection position between the second blank 230 and the second structural piece 242 can be clamped at the bar-shaped through hole 213 (first slot 113).

[0049] According to a preferred embodiment of the present invention, Figure 2 As shown, side structural pieces 214 are provided on both sides of the first main body piece 211 (on both sides of the side connected to the second main body piece 212), and the side structural pieces 214 are rotated and bent relative to the first main body piece 211 to form side walls 114 on both sides of the box body 110.

[0050] In this embodiment, the side wall 114 formed by folding the side structure piece 214 has a second slot on the side close to the second main body surface 112. For example, the side structure piece 214 includes a strip structure with a smaller width, and the structural pieces on both sides of the strip structure are bent to form the second slot, and the width of the second slot is consistent with the width of the strip structure. Figure 2 As shown, the second main body piece 212 further includes an inserting tongue 215 , which can be inserted into the second slot.

[0051] Preferably, the end of the tongue 215 away from the second main body piece 212 is arranged at a substantially right angle. In this embodiment, the angle between the second main body surface 112 and the first main body piece 111 is less than 90°. This increases the contact area between the tongue 215 and the second slot, and allows the tongue 215 to be snapped into the second slot. When the packaging structure 100 is suspended, the tongue 215 and the second slot cooperate, further improving the stability of the packaging structure 100 and reducing the risk of the tongue 215 being dislodged from the second slot.

[0052] In some embodiments, the end of the side structural piece 214 near the second main body surface 112 is a beveled surface, and the angle of the beveled surface is equal to the angle between the first main body surface 111 and the second main body surface 112. The side wall 114 formed by folding the side structural piece 214 close to the second main body surface 112 can close the accommodating space and increase the contact area between the tongue 215 and the second slot.

[0053] According to a preferred embodiment of the present invention, Figure 2 As shown, the connecting piece 240 further includes a supporting piece 243. The supporting piece 243 and the first structural piece 241 are rotatably connected, and after the packaging structure 100 is folded and formed, the supporting piece 243 can be supported in the wedge-shaped cavity between the first main surface 111 and the second main surface 112.

[0054] Specifically, for example Figure 2 As shown in , the support piece 243 includes three sides and is generally triangular in shape. One of the three sides is rotatably connected to the first structural piece 241. When the second main body piece 212 and the first structural piece 241 are bent toward the first main body piece 211, the support piece 243 bends relative to the first structural piece 241, with the two sides of the support piece 243 respectively abutting the first main body piece 211 and the second main body piece 212. The provision of the support piece 243 in this embodiment can improve the structural strength between the first main body surface 111 and the second main body surface 112, thereby reducing the risk of damage to the box body 110 due to pressure.

[0055] Furthermore, the support sheet 243 is roughly arranged in a right triangle, and after the packaging structure 100 is folded and formed, the first structural sheet 241 is roughly perpendicular to the first main body sheet 211. The first structural sheet 241 can provide support for the accommodating space, and the accommodating space is divided into two spaces by the first structural sheet 241, one of which is roughly in the shape of a rectangular parallelepiped and the other is roughly in the shape of a triangular prism. In some embodiments, the two spaces separated by the first structural sheet 241 can accommodate different contents, which is conducive to improving the user experience. Preferably, an operating hole can be opened on the first structural sheet 241, for example, the user can insert a finger into the operating hole to open the triangular prism-shaped space.

[0056] In other embodiments, the support sheet 243 may be rotatably connected to the second structural sheet 242 and supported in the wedge-shaped cavity between the first main body surface 111 and the second main body surface 112. Specifically, the connection position of the support sheet 243 may be selected based on the need to save the area occupied by the sheet 200.

[0057] According to a preferred embodiment of the present invention, the closing portion 120 is made of a third blank 220. For example Figure 2 As shown in FIG, the third blank 220 and the first blank 210 and the second blank 230 are cut from the same sheet 200, which is beneficial to simplifying the production process and reducing processing costs.

[0058] In some embodiments, one side of the closure portion 120 is adhered to the second main surface 112, and the closure portion 120 includes a fragile portion 121. The fragile portion 121 can be broken to separate the side of the closure portion 120 that is not adhered to the second main surface 112 from the second main surface 112, thereby opening the accommodating space.

[0059] Specifically, such as Figure 2 As shown, the third blank 220 is rotatably connected to the first blank 210, and a tear strip 221 is processed on the third blank 220 to form a fragile portion 121. The tear strip 221 may include intermittent through holes to facilitate the user to tear it open. The third blank 220 is on the left side of the tear strip 221 ( Figure 2 An adhesive is applied to the left side of the third blank 220. After the third blank 220 and the first blank 210 are folded, the third blank 220 is adhered and fixed to the second main surface 112 using the adhesive. When the fragile portion 121 is broken, a portion of the closed portion 120 adhered to the second main surface 112 remains adhered to the second main surface 112, while another portion of the closed portion 120 separates from the second main surface 112, revealing the storage space.

[0060] Finally, it should be noted that the above description is merely an embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
