Description

Technical Field

[0001] The utility model relates to the field of packaging materials, in particular to a locking type packaging box. Background Art

[0002] The packaging box is a commonly used packaging tool at present. A packaging box is disclosed in the patent publication document CN208790117U. In the packaging box with this structure, the locked state disclosed therein is realized by the cooperation of a locking tongue (the reference numeral in the document is 9) and a locking hole (the reference numeral in the document is 8). The locking tongue can be inserted into or pulled out of the locking hole at any time according to needs. Therefore, the packaging box with this structure can be opened at any time after being sealed, and can still be sealed again after being opened, and no opening trace will be left after being sealed again. Therefore, its reliability is relatively poor. Content of the Utility Model

[0003] Aiming at the above problems, the utility model provides a locking type packaging box.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A locking type packaging box includes a bottom sheet and a cover sheet. First bottom side sheet, second bottom side sheet, third bottom side sheet and fourth bottom side sheet are sequentially arranged along the periphery of the bottom sheet. The first bottom side sheet, second bottom side sheet, third bottom side sheet and fourth bottom side sheet are distributed in a rectangular shape around the bottom sheet. The bottom sheet, first bottom side sheet, second bottom side sheet, third bottom side sheet and fourth bottom side sheet enclose a box bottom. One end of the cover sheet is cooperated with the third bottom side sheet. The cover sheet is provided with a first cover side sheet, a second cover side sheet and a third cover side sheet. The cover sheet, first cover side sheet, second cover side sheet and third cover side sheet enclose a box cover. An embedding sheet is arranged on the first bottom side sheet, and a clamping sheet is arranged on the second cover side sheet. The clamping sheet and the second cover side sheet are parallel and in close contact. An embedding opening is arranged on the clamping sheet. The embedding sheet is located inside the box bottom, and the clamping sheet and the embedding opening are located inside the box cover. When the box cover and the box bottom are cooperated together, the embedding sheet is clamped between the clamping sheet and the first bottom side sheet.

[0006] In this kind of packaging box, when the box cover and the box bottom start to be closed together, the embedding piece on the first bottom side piece starts to slide into the space between the clamping piece and the second cover side piece through the embedding opening. When the embedding piece is clamped between the clamping piece and the second cover side piece, a locking structure is formed between the embedding piece, the clamping piece and the second cover side piece. Since the embedding piece is located inside the box bottom, and the clamping piece and the embedding opening are located inside the box cover, after the box cover and the box bottom are closed together, the entire locking structure is located inside the box. And because the embedding piece is clamped between the clamping piece and the second cover side piece, when it is necessary to open the box cover, the embedding piece must be broken or the clamping piece must be broken or the second cover side piece must be broken. This is equivalent to that this kind of packaging box can only be opened in a destructive way when it is opened, and when it is opened in a destructive way, an opening trace will inevitably be left.

[0007] To sum up, in this kind of packaging box, a locking structure is formed inside the box after the box cover and the box bottom are closed together. When it is opened again, it can only be opened in a destructive way, and the destructive opening will leave an opening trace.

[0008] Optionally, the clamping piece is provided with a first embedding opening and a second embedding opening, and the first bottom side piece is provided with a first embedding piece and a second embedding piece.

[0009] By setting the first embedding piece and the second embedding piece, when two embedding pieces are clamped between the clamping piece and the second cover side piece, the stability of the locking structure can be improved.

[0010] Specifically, in this kind of packaging box, the first embedding opening is the channel for the first embedding piece to slide into the space between the clamping piece and the second cover side piece, and the second embedding opening is the channel for the second embedding piece to slide into the space between the clamping piece and the second cover side piece.

[0011] Optionally, it further includes a first reinforcing piece, a second reinforcing piece and a third reinforcing piece. The first reinforcing piece is arranged on the first bottom side piece, the second reinforcing piece is arranged on the second bottom side piece, and the third reinforcing piece is arranged on the fourth bottom side piece. The first reinforcing piece, the second reinforcing piece and the third reinforcing piece are all cooperated with the bottom piece. The first reinforcing piece is parallel to the first bottom side piece, the second reinforcing piece is parallel to the second bottom side piece, and the third reinforcing piece is parallel to the fourth bottom side piece.

[0012] The function of setting the first reinforcing piece, the second reinforcing piece and the third reinforcing piece is to strengthen the supporting strength of the first side piece, the second side piece and the fourth side piece, ensure that the finally enclosed box bottom has strong supporting strength, and it is not easy to collapse when several such locking packaging boxes are stacked.

[0013] Optionally, a first auxiliary piece and a second auxiliary piece are provided on the first bottom side piece, a third auxiliary piece and a fourth auxiliary piece are provided on the third bottom side piece, and the first auxiliary piece and the fourth auxiliary piece are clamped between the fourth bottom side piece and the third reinforcing piece; the second auxiliary piece and the third auxiliary piece are clamped between the second bottom side piece and the second reinforcing piece.

[0014] Optionally, a first buckle and a second buckle are provided on the first reinforcing piece, the first buckle is engaged with a first jack on the bottom piece, the second buckle is engaged with a second jack on the bottom piece, a third buckle and a fourth buckle are provided on the second reinforcing piece, the third buckle is engaged with a third jack on the bottom of the box, the fourth buckle is engaged with a fourth jack on the bottom of the box, a fifth buckle and a sixth buckle are provided on the third reinforcing piece, the fifth buckle is engaged with a fifth jack on the bottom of the box, and the sixth buckle is engaged with a sixth jack on the bottom of the box.

[0015] Optionally, a first reinforcing piece is provided on the first lid side piece, a second reinforcing piece is provided on the third lid side piece, and the first reinforcing piece and the second reinforcing piece are clamped between the clamping piece and the second lid side piece.

[0016] By providing the first reinforcing piece and the second reinforcing piece, and clamping the first reinforcing piece and the second reinforcing piece between the clamping piece and the second lid side piece, the stability and strength of the entire lid can be improved, making the entire lid not easily damaged.

[0017] Optionally, the first bottom side piece and the third bottom side piece are in a parallel state, and the second bottom side piece and the fourth bottom side piece are in a parallel state.

[0018] Optionally, the first lid side piece and the third lid side piece are in a parallel state, and the second lid side piece is perpendicular to the first lid side piece and the third lid side piece.

Specific embodiments

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] As shown in the appended Figure 1 and the appended Figure 2 and the appended Figure 3As shown in the figure, a locking packaging box includes a bottom sheet 1 and a cover sheet 3. Along the periphery of the bottom sheet 1, a first bottom side sheet 6, a second bottom side sheet 10, a third bottom side sheet 2, and a fourth bottom side sheet 12 are sequentially arranged. The first bottom side sheet 6, the second bottom side sheet 10, the third bottom side sheet 2, and the fourth bottom side sheet 12 are distributed around the bottom sheet 1 in a rectangular shape. The bottom sheet 1, the first bottom side sheet 6, the second bottom side sheet 10, the third bottom side sheet 2, and the fourth bottom side sheet 12 enclose a box bottom. One end of the cover sheet 3 is cooperated with the third bottom side sheet 2. The cover sheet 3 is provided with a first cover side sheet 16, a second cover side sheet 4, and a third cover side sheet 17. The cover sheet 3, the first cover side sheet 16, the second cover side sheet 4, and the third cover side sheet 17 enclose a box cover. An embedding sheet is arranged on the first bottom side sheet 6, and a clamping sheet 5 is arranged on the second cover sheet 3. The clamping sheet 5 is parallel and close to the second cover side sheet 4. An embedding opening is arranged on the clamping sheet 5. The embedding sheet is located inside the box bottom, and the clamping sheet 5 and the embedding opening are located inside the box cover. When the box cover is cooperated with the box bottom, the embedding sheet is clamped between the clamping sheet 5 and the first bottom side sheet 6.

[0030] In this kind of packaging box, when the box cover starts to be closed with the box bottom, the embedding sheet on the first bottom side sheet 6 starts to slide into the space between the clamping sheet 5 and the second cover side sheet 4 through the embedding opening (the state at this time is as shown in the appendix Figure 4 ). When the embedding sheet is clamped between the clamping sheet 5 and the second cover side sheet 4 (the state at this time is as shown in the appendix Figure 5 ), a locking structure is formed by the embedding sheet being clamped between the clamping sheet 5 and the second cover side sheet 4. Since the embedding sheet is located inside the box bottom, and the clamping sheet 5 and the embedding opening are located inside the box cover, after the box cover is closed with the box bottom, the entire locking structure is located inside the box. And because the embedding sheet is clamped between the clamping sheet 5 and the second cover side sheet 4, when the box cover needs to be opened, the embedding sheet must be broken or the clamping sheet 5 must be broken or the second cover side sheet 4 must be broken. This is equivalent to that this kind of packaging box can only be opened in a destructive way when it is opened. And when it is opened in a destructive way, an opening trace will inevitably be left. The appendix Figure 6 shows the state when the box is opened without breaking the first embedding sheet 20 and the second embedding sheet 21. When the first embedding sheet 20 and the second embedding sheet 21 are not broken, the clamping sheet 5 or the second cover side sheet 4 must be broken.

[0031] It should be specially noted that the arc arrows in the appendix Figure 4 and the appendix Figure 6 represent the rotation direction of the box cover.

[0032] In summary, in this kind of packaging box, a locking structure is formed inside the box after the box cover is closed with the box bottom. When it is opened again, it can only be opened in a destructive way, and the destructive opening will leave an opening trace. This endows the entire packaging box with the function of anti-theft when packaging objects, with stronger reliability and higher security.

[0033] As shown in the attached Figure 1 and the attached Figure 2 and the attached Figure 3 As shown, the clamping piece 5 is provided with a first embedding opening 22 and a second embedding opening 23, and the first bottom side piece 6 is provided with a first embedding piece 20 and a second embedding piece 21.

[0034] By providing the first embedding piece 20 and the second embedding piece 21, when two embedding pieces are clamped between the clamping piece 5 and the second cover side piece 4, the stability of the locking structure can be improved.

[0035] Specifically, in this kind of packaging box, the first embedding opening 22 is a channel for the first embedding piece 20 to slide between the clamping piece 5 and the second cover side piece 4, and the second embedding opening 23 is a channel for the second embedding piece 21 to slide between the clamping piece 5 and the second cover side piece 4.
