DETAILED DESCRIPTION

[0017] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] As shown in Figures 1 and 2, this embodiment designs an adjustable packaging box for containing and taking aluminum foil, including a box body 100, the box body 100 has a accommodating cavity 101, the box body 100 also has a lifting portion 102, the lifting portion 102 is located in the accommodating cavity 101, the box body 100 also has a supporting portion 103, the supporting portion 103 is rotatably arranged, and after rotation, the lifting portion 102 can be lifted up.

[0019] In this embodiment, in order to facilitate the access to aluminum foil, a box body 100 is designed. The box body 100 is a cube formed by folding a whole blank, and has a storage cavity 101 inside for holding the aluminum foil. The storage cavity 101 contains a lifting portion 102 and a supporting portion 103. The supporting portion 103 is rotatably arranged at the bottom of the storage cavity 101, and the lifting portion 102 can be lifted up after rotation. When the amount of aluminum foil remaining in the box body 100 is small, the height of the aluminum foil pile is low and difficult to take, and the supporting portion 103 can be rotated into a vertical state to lift the lifting portion 102, thereby raising the height of the aluminum foil pile, making it easier for users to access the aluminum foil. Existing packaging boxes with a lifting function are usually complex in structure, or adopt a split design, and the manufacturing cost is high. The box body in this embodiment is folded from a single blank, and is simple to manufacture.

[0020] Furthermore, the box body 100 has a bottom plate 104 , a side plate 105 and a top plate 106 . The bottom plate 104 has a through hole 105 , and the support portion 103 is rotatably disposed on a side edge of the through hole 105 .

[0021] In this embodiment, the box body 100 comprises a bottom panel 104, side panels 105, and a top panel 106, which together enclose a receiving cavity 101. The bottom panel 104 has a through hole 105, and one side edge of the support portion 103 is pivotally mounted on one side edge of the through hole 105. The blank is cut from a single sheet of cardboard and can be easily folded into the box body 100, improving the efficiency of paper box production.

[0022] Furthermore, the support portion 103 has the same shape as the through hole 105 . There are two through holes 105 and they are symmetrically arranged. A support portion 103 is rotatably arranged on one side edge of each through hole 105 .

[0023] In this embodiment, the support portion 103 is identical in shape to the through hole 105 and completely covers the through hole 105 before being rotated to a vertical position. There are two symmetrical through holes 105, each with a support portion 103 pivotally mounted on one edge. Once the support portions 103 are rotated to a vertical position, the two support portions 103 stably support the lifting portion 102, keeping it horizontal and preventing the aluminum foil stack from tilting, ensuring smooth access.

[0024] Furthermore, the support portion 103 is trapezoidal and has an inserting portion 107 at its end. The lifting portion 102 has an insertion opening 108 , and the inserting portion 107 is used to be inserted into the insertion opening 108 .

[0025] In this embodiment, the support portion 103 is trapezoidal, which makes the support portion 103 more stable when in a vertical position. The end portion has an inserting portion 107, and the lifting portion 102 has an insertion opening 108. The inserting portion 107 is used to be inserted into the insertion opening 108. After the inserting portion 107 is inserted into the insertion opening 108, it limits the support portion 103, keeps the support portion 103 in a vertical position, and prevents the support portion 103 from rotating when supporting the lifting portion 102, thereby stably supporting the lifting portion 102.

[0026] Furthermore, the insertion opening 108 is square. In this embodiment, the insertion opening 108 is square, and the edges of the square are straight, which can better fit with the straight insertion portion 107, so that the fixing effect after insertion is better.

[0027] Furthermore, the lifting portion 102 includes two connecting bars 109 , both of which are rotatably arranged in the accommodating cavity 101 , a platform plate 110 , and the platform plate 110 is rotatably connected to the connecting bars 109 , and the insertion port 108 is arranged in the middle of the platform plate 110 .

[0028] In this embodiment, the lifting portion 102 includes a connecting bar 109. There are two connecting bars 109, both of which are rotatably arranged in the accommodating cavity 101. One end is rotatably connected to the bottom of the box body 100, and the other end is rotatably connected to the platform plate 110. The insertion port 108 is arranged in the middle of the platform plate 110. When not lifted, the connecting bar 109 and the platform plate 110 are located in the same plane. After lifting, the connecting bar 109 rotates to an inclined state, and the platform plate 110 maintains a horizontal state while increasing in height. After lifting, the position of the insertion port 108 corresponds to the position of the insertion portion 107, so that the insertion portion 107 can be vertically inserted into the insertion port 108. Through the rotational connection between the connecting bar 109 and the platform plate 110, the platform plate 110 can maintain its connection with the box body 100 while being flexibly lifted, preventing the platform plate 110 from shaking at will. At the same time, the box body 100 and the lifting portion 102 are integrated, which facilitates the production of the box body 100.

[0029] Furthermore, the box body 100 has a foil taking-out opening 111 , and the edge of the foil taking-out opening 111 has a perforated line 112 , which extends from the top plate 106 to the side plate 105 . Both ends of the foil taking-out opening 111 are arc-shaped, and the two side plates 105 are a three-layer structure.

[0030] In this embodiment, when the box body 100 is unopened, the foil access opening 111 is sealed. To open the box body 100, tear along the perforated line 112. The ends of the foil access opening 111 are curved, making it easy to tear with your fingers. The two side panels 105 are a three-layer structure, obscuring all gaps on the sides of the box body 100. This improves the sealing performance of the box body 100 and enhances its aesthetics.

[0031] As shown in Figure 3, this embodiment also proposes a packaging box blank for folding into a box body 100, including a plate body 200, the plate body 200 having a through hole 105, and also including a support portion 103, the support portion 103 is rotatably set on the plate body 200, and a lifting portion 102, the lifting portion 102 is rotatably set on the plate body 200, after the plate body 200 is folded into the box body 100, the support portion 103 is used to support the lifting portion 102.

[0032] In this embodiment, when the remaining amount of aluminum foil in the box body 100 is low and the stack is low, making it difficult to access, the support portion 103 can be rotated vertically to lift the lifting portion 102, thereby raising the stack and making it easier for the user to access the aluminum foil. All components of the packaging box are folded from a single blank, making the production process simpler and more efficient than existing products.

[0033] Furthermore, the lifting portion 102 has a first slit 201 , a second slit 202 and a third slit 203 that are connected in sequence. The first slit 201 is perpendicular to the second slit 202 , and the second slit 202 is perpendicular to the third slit 203 .

[0034] In this embodiment, the gaps are connected to form a ⌚-shaped gap. This ⌚-shaped gap separates the connecting strip 109 and the platform plate 110 while maintaining the integrity of the plate body 200. This facilitates processing, is cost-effective, and effectively improves production efficiency. A connecting strip 109 is pivotally connected to each side of the platform plate 110. The ⌚-shaped gap makes the plate body 200 easier to bend, allowing the platform plate 110 to be lifted and the connecting strip 109 to be tilted.

[0035] Furthermore, both the end of the first slit 201 away from the second slit 202 and the end of the third slit 203 away from the second slit 202 have an enlarged portion 204 .

[0036] In this embodiment, the end of the connecting bar 109 is adjacent to the enlarged portion 204. When the plate 200 is lifted, the end of the connecting bar 109 rotates. The enlarged portion 204 makes the plate 200 narrower at this point, making it easier to bend.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
