[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] Please refer to Figure 1 , Figure 2 and Figure 3 The folding packaging box 100 provided in Embodiment 1 of this utility model includes a cover plate 1 and a box body 3. Specifically, the box body 3 includes a first surrounding plate 31, a second surrounding plate 32, and a bottom plate 35; the bottom plate 35 is disposed between the first surrounding plate 31 and the second surrounding plate 32. The first surrounding plate 31 includes a first folding plate 311, a second folding plate 312, and a third folding plate 313. The second surrounding plate 32 includes a fourth folding plate 321, a fifth folding plate 322, and a sixth folding plate 323. The cover plate 1 and the bottom plate 35 are symmetrically arranged; the cover plate 1 is connected to one end of either the first surrounding plate 31 or the second surrounding plate 32. Specifically, after the second surrounding plate 32 is bent, the second folding plate 312, the fourth folding plate 321, the fifth folding plate 322, the sixth folding plate 323, the bottom plate 35, and the cover plate 1 enclose a square box body. The square box body 3 has a square inner cavity.
[0031] In this embodiment, the second folding plate 312 is parallel to the fifth folding plate 322; the horizontal side lengths of the second folding plate 312 and the fifth folding plate 322 are equal. The fourth folding plate 321 is parallel to the sixth folding plate 323; the horizontal side lengths of the fourth folding plate 321 and the sixth folding plate 323 are equal. The length of the first side of the base plate 35 is equal to the length of the horizontal side of either the second folding plate 312 or the fifth folding plate 322; the length of the second side of the base plate 35 is equal to the length of the horizontal side of either the fourth folding plate 321 or the sixth folding plate 323. The vertical side lengths of the second folding plate 312 and the fifth folding plate 322, and the vertical side lengths of the fourth folding plate 321 and the sixth folding plate 323 are all equal. Thus, the second folding plate 312, the fifth folding plate 322, the fourth folding plate 321, the sixth folding plate 323, and the base plate 35 enclose a square cavity of the box body 3.
[0032] Please refer to Figure 3 Preferably, the first folding plate 311 and the third folding plate 313 bend into the cavity of the box body 3, dividing the cavity of the box body 3 into several spaces. In this way, a cavity that can be appropriately matched to accommodate the object can be found according to the shape and size of the object.
[0033] Further, please refer to Figure 4 and Figure 5Two parallel slits 8 are provided near the connection between the mutually perpendicular base plate 35 and the second folding plate 312, penetrating the base plate 35 and the second folding plate 312. When the second folding plate 312 bends towards the base plate 35, the portion of the second folding plate 312 and the base plate 35 between the two slits 8 is recessed inward, and bends at the connection between the second folding plate 312 and the base plate 35, forming a step 6 within the cavity of the box body 3. Specifically, the step 6 is located within the cavity formed by the first folding plate 311, the second folding plate 312, and the third folding plate 313. In this way, the spatial dimensions of the cavity formed between the first folding plate 311, the second folding plate 312, the third folding plate 313, and the base plate 35 are further adjusted. When the height of an item placed in this cavity is less than the height of the box body 3, placing the item on the step 6 can raise the placement height of the item; thereby reducing the distance between the item and the cover plate 1, making it easier to retrieve the item by opening the cover plate 1. Understandably, the specific height of step 6 can be adjusted adaptively based on the height difference between the item and the box 3.
[0034] When the cavity formed by the first folding plate 311, the second folding plate 312, the third folding plate 313, and the base plate 35 is the main receiving cavity, that is, when the item is placed only in the main receiving cavity, more preferably, please refer to Figure 4 The first folding plate 311 and the third folding plate 313 have a first notch and a second notch respectively on their end faces near the cover plate 1; and the first notch and the second notch are symmetrically arranged. In this way, the first notch and the second notch can make it easier to take out the items placed in the cavity. Furthermore, the end face of the cover plate 1 near the second folding plate 312 has a third notch, that is, a notch is provided at the opening of the cover plate 1 to facilitate opening the cover plate 1.
[0035] In the first embodiment, please refer to Figures 3 to 6 , Figures 7 to 12 The lengths 311a and 313a of the parallel sides of the first folding plate 311 and the third folding plate 313 are greater than the length of the parallel side 321a of the fourth folding plate 321, the length of the parallel side 323a of the sixth folding plate 323, or the length of the second side of the base plate 35. The first folding plate 311 and the third folding plate 313 are bent into the cavity of the box body 3 and connected to the fifth folding plate 322 respectively, which can divide the cavity of the box body 3 into three spaces 30a, 30b, and 30c respectively. In an alternative embodiment, the first folding plate 311 and the third folding plate 313 are bent into the cavity of the box body 3 and connected to each other, which can also divide the cavity into three spaces 30a, 30b, and 30c. Specifically, the space formed by the first folding plate 311, the second folding plate 312, the third folding plate 313, and the base plate 35 is the cavity 30a.
[0036] Understandably, in the square box 3, the lengths of the second side of the base plate 35, the parallel side 321a of the fourth fold plate 321, and the parallel side 323a of the sixth fold plate 323 are all equal. The lengths of the first side of the base plate 35, the parallel side 322a of the fifth fold plate 322, and the parallel side 312a of the second fold plate 312 are all equal. Furthermore, the length of the parallel side 322a of the fifth fold plate 322 is equal to the length of the parallel side 1a of the cover plate.
[0037] Please refer to the following: Figure 6 , Figure 7 and Figure 8 The parallel sides 311a and 313a of the first folding plate 311 and the third folding plate 313 are of equal length. The first folding plate 311 and the third folding plate 313 are bent into the cavity of the box body 3 and simultaneously connected to the center line of the fifth folding plate 322; or, the first folding plate 311 and the third folding plate 313 are bent into the cavity of the box body 3 and connected to each other, dividing the cavity of the box body 3 into three triangular spaces. At this time, the triangular cavity 30a formed by the first folding plate 311, the second folding plate 312, the third folding plate 313 and the bottom plate 35 is an isosceles triangular cavity.
[0038] For details, please refer to Figure 5 The end faces of the third folding plate 313 and the first folding plate 311 away from the second folding plate 312 are respectively provided with protrusions 5a and 5b. Correspondingly, two first slots 6a and 6b are respectively opened on the fifth folding plate 322 to mate with the protrusions 5a and 5b. The first slots 6a and 6b are on the same straight line. The first folding plate 311 and the third folding plate 313 are connected to the same position on the fifth folding plate through the cooperation of the protrusions 5a and 5b and the first slots 6a and 6b. It should be noted that the above is only one connection method, but is not limited to this connection method.
[0039] Furthermore, when the lengths of the parallel sides of the first fold plate 311, the second fold plate 312, the third fold plate 313, the fourth fold plate 321, the fifth fold plate 322, and the sixth fold plate 323 are all equal, the base plate 35 is a square; the cavity 30a formed by the first fold plate 311, the second fold plate 312, and the third fold plate 313 is an equilateral triangular cavity.
[0040] Please refer to Figure 9 When the lengths of the parallel sides 311a of the third fold plate 313 and 313a of the first fold plate 311 are not equal, the first fold plate 311 and the third fold plate 313 bend into the cavity of the box 3 and simultaneously connect to the same position of the fifth fold plate 322, which can also divide the cavity of the box 3 into three triangular spaces. However, at this time, the triangular cavity 30a formed by the first fold plate 311, the second fold plate 312, the third fold plate 313 and the bottom plate 35 is a non-isosceles triangle.
[0041] Please refer to Figure 10 , Figure 11 and Figure 12 When the first folding plate 311 and the third folding plate 313 bend into the cavity of the box body 3 and connect to different positions of the fifth folding plate, the first folding plate 311 and the third folding plate 313 divide the square cavity of the box body 3 into a trapezoidal cavity and two triangular cavities. Specifically, the cavity 30a formed by the first folding plate 311, the second folding plate 312, the third folding plate 313 and the bottom plate 35 is a trapezoidal cavity.
[0042] In the second embodiment, please refer to Figures 13 to 16 The difference between this embodiment and the first embodiment is that the lengths of the parallel sides of the first folding plate 311 and the third folding plate 313 are less than the length of the second side of the base plate 35, or the length of the parallel side 321a of the fourth folding plate 321, or the length of the parallel side 323a of the sixth folding plate 323.
[0043] Specifically, the first folding plate 311 and the third folding plate 313 are folded into the cavity of the box body 3 and connected to each other; the cavity of the box body 3 is divided into two spaces 30g and 30h. Space 30g is a triangular cavity formed by the first folding plate 311, the second folding plate 312, and the third folding plate 313 enclosing the cavity of the box body 3.
[0044] Please refer to the following: Figures 13 to 15 When the lengths of the parallel sides 311a and 313a of the first fold plate 311 and the third fold plate 313 are equal, the triangular cavity 30g formed by the first fold plate 311, the second fold plate 312 and the third fold plate 313 enclosing the cavity of the box body 3 is an isosceles triangular cavity.
[0045] Please refer to Figure 16 When the lengths of the parallel sides 311a and 313a of the first fold plate 311 and the third fold plate 313 are not equal, the triangular cavity 30g formed by the first fold plate 311, the second fold plate 312 and the third fold plate 313 enclosing the cavity of the box body 3 is a non-isosceles triangular cavity.
[0046] The above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, such as combining different features in various embodiments, and these all fall within the protection scope of the present invention.
