Description

Technical Field

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

[0002] The folding packaging box is a commonly used packaging tool at present. A commonly used folding packaging box is disclosed in the patent publication document CN203946339U. The folding packaging box shown in this structure is formed by cutting and folding a whole piece of paper. There is a problem in the use process of this structure of the folding packaging box, that is, there is no direct fixation between the cover piece (i.e., the piece of paper with an opening) of this structure of the packaging box and the first fixing piece (the serial number of the attached drawing reference in the document is 12). Therefore, after the packaging box of this structure is sealed, there is a gap between the cover piece and the first fixing piece. In order to ensure the tightness at this place, it is necessary to apply glue between the first fixing piece and the cover piece. Applying glue is inconvenient for operation during sealing and is not conducive to subsequent opening of the box. Summary of the Utility Model

[0003] In view of the above problems, the utility model provides a packaging box. Both ends of the sealing cover piece are connected with connecting pieces, and both ends of the connecting piece are connected with the sealing cover piece and the box body respectively. In this way, the sealing cover piece and the connecting piece can ensure the tightness between them without applying glue during box sealing, which is convenient for operation and subsequent opening of the box.

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

[0005] A packaging box includes a box body. The box body is provided with a box opening. A sealing cover piece and a connecting piece are arranged at the box opening of the box body. Both ends of the connecting piece are respectively connected with the sealing cover piece and the box body. Both ends of the sealing cover piece are connected with the connecting piece. The sealing cover piece is connected with an adhesive piece. The box body, the sealing cover piece, the adhesive piece and the connecting piece are integrally formed. The connecting piece is provided with a folding line, and the adhesive piece is provided with a tearing strip.

[0006] In this kind of packaging box, a sealing cover piece and a connecting piece are arranged on the box body. The box body, the sealing cover piece, the connecting piece and the adhesive piece are integrally formed. Both ends of the connecting piece are respectively connected with the sealing cover piece and the box body. When sealing the box, the sealing cover piece blocks the box opening of the box body, and the adhesive piece is adhered to the outer wall of the box body. At this time, the box sealing is completed. After the box sealing is completed, since both ends of the sealing cover piece are connected with connecting pieces, and both ends of the connecting piece are connected with the sealing cover piece and the box body respectively, the sealing cover piece and the connecting piece can ensure the tightness between them without applying glue during box sealing, which is convenient for operation and subsequent opening of the box.

[0007] In this kind of packaging box, the connecting piece itself is provided with a folding line. The existence of the folding line is convenient for the connecting piece to be bent during box sealing, ensuring that the sealing cover piece can rotate smoothly to cover the box opening of the box body.
