[0038] Please refer to Figures 1 to 4 , Figure 1 It is a schematic view of the packaging box according to the first embodiment. Figure 2 It is a schematic view of the packaging box according to the first embodiment. Figure 1 It is a schematic view of the packaging box according to the first embodiment. Figure 3 It is a schematic view of the packaging box according to the first embodiment.Figure 2 Fig. 2 is a schematic view of the accessory case separated from the packaging case; Figure 4 Fig. 1 is a schematic view of the packaging case according to a first embodiment of the present application; Figure 2 Fig. 2 is a schematic view of the accessory case separated from the packaging case; Figure 4 Fig. 1 is a schematic view of the packaging case according to a first embodiment of the present application. The packaging case 1 is made of a sheet material, and for simplicity of the drawing, the outline of the sheet material is shown in thick solid lines, the folding lines of the sheet material are shown in thin solid lines, and the thickness of the sheet material is not shown. The packaging case 1 comprises a container portion 12 and a movable restraining mechanism 14. The container portion 12 forms a receiving space 12a and an opening 12b (see Fig. 1) communicating with the receiving space 12a. The opening 12b faces upward (i.e., parallel to a vertical direction Dv (indicated by double-headed arrows in the figures) upward). In an embodiment, the packaging case 1 further comprises a lid 10 fixedly connected to one side of the opening 12b, so that the lid 10 can be rotated relative to the container portion 12 to cover the opening 12b (i.e., the packaging case 1 is in a closed state) or expose the opening 12b (i.e., the packaging case 1 is in an open state). The movable restraining mechanism 14 is disposed in the receiving space 12a. The movable restraining mechanism 14 comprises a first restraining structure 142 and a second restraining structure 144. The first restraining structure 142 and the second restraining structure 144 are located on opposite sides of the receiving space 12a in a first horizontal direction Dh1 (indicated by double-headed arrows Dh1 in the figures), and further, the first restraining structure 142 and the second restraining structure 144 can abut against opposite side walls 122, 124 of the container portion 12 in the first horizontal direction Dh1. The first restraining structure 142 and the second restraining structure 144 both extend parallel to a second horizontal direction Dh2 (indicated by double-headed arrows Dh2 in the figures). The first horizontal direction Dh1, the second horizontal direction Dh2, and the vertical direction Dv are perpendicular to each other. In an embodiment, the movable restraining mechanism 14 further comprises a connecting bottom plate 146 connecting the first restraining structure 142 and the second restraining structure 144.

[0039] In addition, in an embodiment, the packaging case 1 further comprises a first horizontal restraining structure 16 and a second horizontal restraining structure 18 disposed in the receiving space 12a. The first horizontal restraining structure 16 and the second horizontal restraining structure 18 are disposed on opposite sides of the receiving space 12a in the second horizontal direction Dh2, and further, the first horizontal restraining structure 16 and the second horizontal restraining structure 18 can abut against or be connected to opposite side walls 126, 128 of the container portion 12 in the second horizontal direction Dh2. A receiving space 1a is defined between the first restraining structure 142, the second restraining structure 144, the first horizontal restraining structure 16, and the second horizontal restraining structure 18, to receive an article 3 (such as, but not limited to, a keyboard, represented simply by a square) to be packaged. Figure 2 The article 3 is shown by a chain line, for example, but not limited to, a keyboard, represented simply by a square).

[0040] Further, please refer to Figure 5 which is Figure 1A cross-sectional view of the middle package 1 along the line X-X. The first restraining structure 142 has a first horizontal limiting portion 1422 and a first hook portion 1424 in the vertical direction Dv. The first hook portion 1424 is closer to the opening 12b than the first horizontal limiting portion 1422 in the vertical direction Dv, and protrudes inside the accommodating space 12a (or the article accommodating space la; in the embodiment, both are represented by dashed lines). In an embodiment, the first restraining structure 142 is connected to the connecting bottom plate 146 via the first horizontal limiting portion 1422. Similarly, the second restraining structure 144 has a second horizontal limiting portion 1442 and a second hook portion 1444 in the vertical direction Dv. The second hook portion 1444 is closer to the opening 12b than the second horizontal limiting portion 1442 in the vertical direction Dv, and protrudes inside the accommodating space 12a (or the article accommodating space la; in the embodiment, both are represented by dashed lines). In an embodiment, the second restraining structure 144 is connected to the connecting bottom plate 146 via the second horizontal limiting portion 1442. The first hook portion 1424 and the second hook portion 1444 have a first distance dl in the first horizontal direction Dh1, and the first horizontal limiting portion 1422 and the second horizontal limiting portion 1442 have a second distance d2 in the first horizontal direction Dh1. The first distance dl is smaller than the second distance d2. The first hook portion 1422 or the second hook portion 1444 can be operated to increase the first distance dl. In an embodiment, the first hook portion 1422 rotates around a rotation axis parallel to the second horizontal direction Dh2 to increase the first distance dl. Figure 5 Figure 5 The first hook portion 1422 and the second hook portion 1444 jointly provide limiting of the article to be packaged 3 in the vertical direction Dv. In addition, as shown in Figs. 2 and 3, in an embodiment, the upper cover 10 has pressing portions that press against the hook portions when the upper cover 10 covers the opening 12b. For example, the upper cover 10 has a cover body 102, a first pressing portion 104, and a second pressing portion 106, which are arranged on opposite sides of the cover body 102 in the first horizontal direction Dh1. When the upper cover 10 covers the opening 12b, the first pressing portion 104 and the second pressing portion 106 press against the first hook portion 1424 and the second hook portion 1444, respectively, enhancing the limiting effect of the first hook portion 1424 and the second hook portion 1444 on the article to be packaged 3 in the vertical direction Dv. Further, the article to be packaged 3 can be fixed by the first hook portion 1424 and the second hook portion 1444 abutting against the article to be packaged 3.

[0041] As shown in Figs. 2 and 3, the length of the article to be packaged 3 in the first horizontal direction Dh1 is smaller than the second distance d2 and greater than the first distance dl, so the first hook portion 1424 and the second hook portion 1444 jointly provide limiting of the article to be packaged 3 in the vertical direction Dv. In addition, as shown in Figs. 2 and 3, in an embodiment, the upper cover 10 has pressing portions that press against the hook portions when the upper cover 10 covers the opening 12b. For example, the upper cover 10 has a cover body 102, a first pressing portion 104, and a second pressing portion 106, which are arranged on opposite sides of the cover body 102 in the first horizontal direction Dh1. When the upper cover 10 covers the opening 12b, the first pressing portion 104 and the second pressing portion 106 press against the first hook portion 1424 and the second hook portion 1444, respectively, enhancing the limiting effect of the first hook portion 1424 and the second hook portion 1444 on the article to be packaged 3 in the vertical direction Dv. Further, the article to be packaged 3 can be fixed by the first hook portion 1424 and the second hook portion 1444 abutting against the article to be packaged 3. Figure 5 Figure 2 Figure 5

[0042] In an embodiment, as shown in Fig. 4, the first restraining structure 142 and the second restraining structure 144 are arranged on opposite sides of the connecting bottom plate 146 in the first horizontal direction Dh1.​​​​Figure 5 and Figure 6 As shown, the first hook portion 1424 includes an inclined plate 1424a and a horizontal plate 1424b. The inclined plate 1424a is not perpendicular to the vertical direction Dv and is parallel to the second horizontal direction Dh2 (i.e., parallel to the vertical direction Dv). Figure 5 as well as Figure 6 The direction perpendicular to the cross section, Figure 5 as well as Figure 6 (Not shown in the image) Extends. The horizontal plate 1424b extends perpendicular to the vertical direction Dv and parallel to the second horizontal direction Dh2. The inclined plate 1424a and the horizontal plate 1424b are connected along the second horizontal direction Dh2 to form a structure protruding toward the inside of the accommodating space 12a. The horizontal plate 1424b is closer to the opening 12b in the vertical direction Dv than the inclined plate 1424a. The first hook portion 1424 is connected to the first horizontal limiting portion 1422 (in this embodiment, generally the vertical plate portion) along the second horizontal direction Dh2 via the inclined plate 1424a. In one embodiment, the first restraint structure 142 further includes a vertical plate 1426, which is connected to the vertical plate 1426 (of the first restraint structure 142) along the second horizontal direction Dh2 via the horizontal plate 1424b. The lower edge of the vertical plate 1426 abuts against the bottom 130 of the container portion 12. In this way, the horizontal plate 1424b can be operated to rotate about a rotation axis parallel to the second horizontal direction Dh2 (that is, a direction perpendicular to the paper, indicated by circles and crosses in the figure; roughly equivalent to the connecting edge of the horizontal plate 1424b and the vertical plate 1426), and in turn, rotate the inclined plate 1424a, so that the first hook portion 1424 can also theoretically be regarded as rotating about the rotation axis (for example, after rotation as...). Figure 6 As shown), this increases the first spacing d1. Furthermore, in one embodiment, when the horizontal plate 1424b rotates, it also activates the first horizontal limiting part 1422 via the inclined plate 1424a, and lifts the connecting base plate 146 via the first horizontal limiting part 1422. Additionally, when the upper cover 10 covers the opening 12b, the first pressing part 104 presses against the horizontal plate 1424b.

[0043] In one embodiment, the first restraining structure 142 and the second restraining structure 144 are identical and symmetrical, and thus the second protruding portion 1444 also comprises an inclined plate 1444a and a horizontal plate 1444b connected to the inclined plate 1444a. The second protruding portion 1444 is connected to the second horizontal limiting portion 1442 via the inclined plate 1444a, and is connected to the vertical plate 1446 (of the second restraining structure 144) via the horizontal plate 1424b. The lower edge of the vertical plate 1446 abuts against the bottom 130 of the container portion 12. In this way, the horizontal plate 1444b can be operated to rotate about an axis of rotation parallel to the second horizontal direction Dh2 (i.e. a direction perpendicular to the paper plane, denoted by a circle and a cross in the figure), and in turn rotates the inclined plate 1444a, so that the second protruding portion 1444 can also be regarded as rotating (e.g. after rotation, as shown in Figure 6 The other descriptions of the second restraining structure 144 can be directly referred to the relevant descriptions of the first restraining structure 142 above, and will not be repeated. In other embodiments, the first restraining structure 142 and the second restraining structure 144 are not identical.

[0044] Therefore, the first protruding portion 1424 and the second protruding portion 1444 can both be operated to increase the first spacing dl, so as to facilitate the placement of the to-be-packaged article 3 into the article accommodating space la (e.g. by making the first spacing dl greater than the length of the to-be-packaged article 3 in the first horizontal direction Dh1). In actual applications, after the to-be-packaged article 3 is placed, the to-be-packaged article 3 can press the connecting bottom plate 146 by gravity, so that the first protruding portion 1424 and the second protruding portion 1444 are automatically rotated in reverse to the state as shown in Figure 5 Finally, the upper cover 10 is closed, so that the first pressing portion 104 and the second pressing portion 106 press against the horizontal plate 1424b of the first protruding portion 1424 and the horizontal plate 1444b of the second protruding portion 1444, respectively, and thus the packaging operation is completed. Therefore, compared with the prior art, the packaging box 1 of the utility model can complete the packaging operation of the article using fewer packaging components, thereby reducing the cost of packaging.

[0045] Furthermore, in one embodiment, the first horizontal restraining structure 16 is directly connected to the container portion 12, for example, the side wall 126 of the container portion 12. In one embodiment, the connecting bottom plate 46 connects the first horizontal restraining structure 16 and the second horizontal restraining structure 18, in particular, the connecting bottom plate 46 connects the first horizontal limiting portion 1422 and the second horizontal limiting portion 1442. Further, the first horizontal restraining structure 16 can be directly connected to the container portion 12. The movable restraining mechanism 14 (of the connecting bottom plate 146) is connected to the container portion 12 (of the side wall 126) via the first horizontal restraining structure 16. In one embodiment, the first horizontal restraining structure 16 extends along the first horizontal direction Dh1, and both ends 16a thereof are in contact with the first restraining structure 142 and the second restraining structure 144, respectively. Each end 16a has a gap 16b in the vertical direction Dv with the connecting bottom plate 146. The gap 16b provides a movable allowance when the connecting bottom plate 146 is lifted by the linkage of the first horizontal limiting portion 1422 or the second horizontal limiting portion 1442, and thus facilitates the rotation operation (as described above) of the first protruding hook portion 1424 and the second protruding hook portion 1444 to increase the first spacing d1.

[0046] In addition, please refer to Figure 2 and Figure 3 . The connecting bottom plate 146 has an opening 1462 and a plurality of supporting portions 1464 extending downward from the periphery of the opening 1462, and the plurality of supporting portions 1464 abut against the bottom 130 of the container portion 12, thereby enhancing the supporting strength of the connecting bottom plate 146. Furthermore, in one embodiment, the packaging box 1 further comprises an accessory box 20, which is detachably accommodated in the opening 1462. When the accessory box 20 is accommodated in the opening 1462, the top surface 20a of the accessory box 20 is substantially not higher than the upper surface 146a of the connecting bottom plate 146 in the vertical direction Dv, for example, coplanar. Please refer to Figure 7 , which is a structure enlarged view of the connecting bottom plate 146 at the opening 1462. In one embodiment, the connecting bottom plate 146 has a limiting piece 1466 and a movable blocking piece 1468. The limiting piece 1466 extends from the first edge 1462a of the opening 1462 toward the inside of the opening 1462. The movable blocking piece 1468 extends from the second edge 1462b of the opening 1462 toward the inside of the opening 1462, and is rotatable relative to the second edge 1462b. The first edge 1462a is opposite to the second edge 1462b. When the accessory box 20 is arranged in the opening 1462, the limiting piece 1466 and the movable blocking piece 1468 press against the top surface 20a of the accessory box 20.

[0047] Furthermore, in an embodiment, the movable flap 1468 has an edge section 1468a and is connected to the second edge 1462b via the edge section 1468a. The edge section 1468a is directly and partially connected to the second edge 1462b, for example by a cut made by a toothed cutter. The edge section 1468a comprises a first end connection 1468b, a second end connection 1468c, a plurality of intermediate connections 1468d, and a plurality of intermediate non-connections 1468e, which are arranged alternately between the first end connection 1468b and the second end connection 1468c along the edge section 1468a. The first end connection 1468b, the second end connection 1468c, and the plurality of intermediate connections 1468d are directly connected to the second edge 1462b, and the plurality of intermediate non-connections 1468e are not directly connected to the second edge 1462b. The length L1 of the intermediate connections 1468d along the edge section 1468a is greater than the length L2 of the first end connection 1468b along the edge section 1468a, and greater than the length L3 of the second end connection 1468c along the edge section 1468a. In actual use, the removal of the accessory case 20 will break the connection between the movable flap 1468 and the second edge 1462b; in principle, the first end connection 1468b and the second end connection 1468c will break, and the plurality of intermediate connections 1468d can remain connected. This structural feature can be used as an important basis for judging whether the accessory case 20 has been removed from the opening 1462. Furthermore, in an embodiment, the sum of the lengths of the plurality of intermediate non-connections 1468e along the edge section 1468a is greater than the sum of the lengths of the first end connection 1468b, the second end connection 1468c, and the plurality of intermediate connections 1468d along the edge section 1468a; but in actual application, it is not limited thereto.

[0048] Furthermore, in an embodiment, the second edge 1462b has a notch 1462c. The edge section 1468a of the movable flap 1468 is connected to the edge of the notch 1462c, and the movable flap 1468 extends from the edge of the notch 1462c towards the inside of the opening 1462. The first end connection 1468b and the second end connection 1468c are connected to the two ends of the edge of the notch 1462c. When the movable flap 1468 is rotated upwards relative to the second edge 1462b, the first end connection 1468b and the second end connection 1468c are separated from the edge of the notch 1462c, the plurality of intermediate connections 1468d remain connected to the edge of the notch 1462c, and the notch 1462c forms a clearance space with the accessory case 20, which can be used for a user to insert a finger to facilitate the removal of the accessory case 20 from the opening 1462. In addition, in this embodiment, a dent is formed on the connection between the limiting piece 1466 and the first edge 1462a to allow the limiting piece 1466 to rotate slightly relative to the first edge 1462a.

[0049] In addition, in one embodiment, the movable restraining mechanism 14 (together with the first horizontal restraining structure 16 and the second horizontal restraining structure 18) is formed by folding the same sheet of paperboard (see also Figures 2 to 4 ); further, in one embodiment, the packaging box 1 (excluding the accessory box 20) can also be formed by folding the same sheet of paperboard. For example, see Figure 8 , which is a schematic view of a foldable paperboard 4 according to an embodiment; wherein the outline of the foldable paperboard 4 is shown in thick solid lines, and the fold lines thereon are shown in thin solid lines. By this, the foldable paperboard 4 can be used to fold the aforementioned packaging box 1 (excluding the accessory box 20). Wherein part 4a of the foldable paperboard 4 (the range of which is shown in a chain line frame) can be folded mainly into the upper cover 10, part 4b of the foldable paperboard 4 (the range of which is shown in a chain line frame) can be folded mainly into the container portion 12, and part 4c of the foldable paperboard 4 (the range of which is shown in a chain line frame) can be folded mainly into the movable restraining mechanism 14, the first horizontal restraining structure 16 and the second horizontal restraining structure 18. Sub-parts 4d, 4e in part 4c (the ranges of which are shown in chain line frames) form the first restraining structure 142 and the second restraining structure 144, respectively. In practical applications, the packaging box 1 (excluding the accessory box 20) can also be formed by folding other unfolded layouts of sheet, can also be formed by folding and combining a plurality of sheets, or can be made of non-sheet, all of which are not described in detail.

[0050] In summary, the packaging box of the present application can complete the packaging operation of the articles by using fewer packaging components, thereby reducing the cost of packaging.

[0051] Of course, the present application can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should all belong to the protection scope of the claims attached to the present application.
