Description

Technical Field

[0001] The utility model relates to a packaging box, in particular to a packaging box for columnar objects. Background Art

[0002] At present, the packaging boxes for column-shaped objects on the market usually use airplane box structures, scroll packaging boxes, and scroll barrel packaging boxes. The airplane box structure is stable and the column-shaped object is not easy to fall out of the packaging box, but this structure is not easy to open, which makes the packaging box easily damaged when opening, making it unusable. The fixation between the lid and the box body of the scroll packaging box relies on the connecting pieces on both sides. This structure has high cost and poor drop resistance, and is not often used on general column-shaped objects. The scroll barrel packaging box is fixed by mutual socketing. If the column is heavy, when the packaging box is picked up in the wrong direction, the column is easily pushed open as the lid, causing the column to fall out and cause damage.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model discloses a packaging box, including a body 1, which includes a first box body 2 and a second box body 3 that can be separated from each other. The first box body 2 and the second box body 3 are both made of cardboard, which can be corrugated cardboard. The first box body 2 and the second box body 3 are rectangular parallelepipeds, each including two square faces and four rectangular faces. The first box body 2 and the second box body 3 both have an inner cavity. An opening 21 is provided on one square face of the first box body 2, and the other square face is set as a closed face. The opening 21 is connected to the inner cavity of the first box body 2, and the two square faces of the second box body 3 are set as closed faces. In the utility model, the cross-sectional size of the first box body 2 is larger than that of the second box body 3, so that the first box body 2 is The box body 2 can be put on the second box body 3 through the opening 21, and an integrated extension arm 22 is provided on one side edge of the opening 21. A groove body 32 adapted to the extension arm 22 is provided on the outer wall of a rectangular surface of the second box body 3. The groove body 32 is communicated with the inner cavity of the second box body 3. When the first box body 2 and the second box body 3 are sleeved, the extension arm 22 is inserted into the groove body 32 from the outside of the second box body 3 to achieve a relatively fixed connection between the first box body 2 and the second box body 3. After the extension arm 22 is inserted, the surface of the extension arm 22 is in close contact with the edge of the groove body 33 away from the second opening 31 and the inner wall of the rectangular surface of the second box body 3, thereby achieving a more stable connection between the first box body 2 and the second box body 3.

[0018] The groove 32 extends toward the square surface of the second housing 3 opposite the first housing 2, forming an opening for inserting a column. To increase the cavity, inwardly folded second portions 31 are provided at both ends of the long sides of the groove 32. The second folds 31 are integrally connected to the edges of the groove 32. The second folds 31 not only strengthen the edges of the groove 32 but also provide protection by cushioning the sides of the inserted column.

[0019] like Figure 2 and Figure 4 As shown, the end of the extension arm 22 away from the opening 21 is provided with a first folded portion 23 that is folded outward and is integrated. The inner cavity of the second box body 3 and the edge of the end of the groove body 32 away from the first box body 2 are provided with an abutment portion 33. When the extension arm 22 is inserted into the groove body 32, the first folded portion 23 and the abutment portion 33 are away from each other. When the first box body 2 and the second box body 3 are separated, the first folded portion 23 and the abutment portion 33 abut against each other and cannot be separated smoothly, thereby further improving the stability of the connection between the first box body 2 and the second box body 3.

[0020] from Figure 4 It can be seen that the abutment portion 33 is formed by an extension portion provided on the edge of the groove body 32 folded toward the inside of the second box body 3 and fixed to the inner wall of the second box body 3. The extension portion is integrally connected to the groove body 32 to prevent it from falling off.

[0021] However, the present invention is not limited to this. The first folded portion 23 may not be glued and fixed to the extension arm 22, and the abutting portion 33 may not be glued and fixed to the inner wall of the second box body 3. In this way, after the extension arm 22 is inserted into the groove body 31, the first folded portion 23 and the abutting portion 33 are misaligned. In this way, when the first box body 2 and the second box body 3 are pulled apart, the first folded portion 23 is inserted between the abutting portion 33 and the inner wall, making it difficult for the two to be opened. When the opening is forcibly opened, the first box body 2 or the second box body 3 will be damaged. This can prevent the columnar objects inside from being replaced and then reloaded for secondary sale.

[0022] like Figure 2 As shown, a contraction edge 24 is provided at one end of the extension arm 22 away from the opening 21 , and the contraction edge 24 gradually contracts toward the other end of the extension arm 22 away from the opening 21 .

[0023] In the present invention, the second box body 3 may adopt an airplane box structure, and the groove body 31 is opened on one side of the cover.

[0024] The utility model has a feature of close contact between the extension arm and the slot body and the inner cavity wall of the second box body 3, which improves the stability of the connection between the first box body 2 and the second box body 3.
