Description

Technical Field

[0001] The utility model belongs to the technical field of cartons, and particularly relates to a folding and flipping carton. Background Art

[0002] A carton is a common packaging material in daily life. When producing a carton, generally, a whole piece of cardboard is used. Through folding, flipping, and then bonding with glue, a box structure is formed. When the carton is not in use, although the carton can be folded and stored again, before storage, all the glue or tape used for bonding needs to be removed, which has certain drawbacks. First, removing the glue and tape brings a certain amount of workload, which causes inconvenience to the folding and storage of the carton. Second, after removal, if the carton needs to be used again later, it is even more troublesome to reattach the glue and tape, which is not conducive to the repeated use of the carton. Therefore, it is necessary to design a new carton to solve this problem. Content of the Utility Model

[0003] The purpose of the utility model is to provide a folding and flipping carton to solve the problems of inconvenient removal of glue and tape during folding of the carton and being not conducive to the repeated use of the carton as mentioned in the above background art.

The connecting component includes a plastic strip, a connecting piece, a threaded column, a strip-shaped groove, a plastic sheet, a card hole, and a threaded fastening cover. The plastic strip is fixed at the end of the bottom plate. The connecting piece is telescopically connected to the end of the plastic strip. The threaded column is fixed on the inner surface of the connecting piece. The strip-shaped groove is opened on the surface of the paper frame. The plastic sheet is fixed inside the strip-shaped groove. The threaded column penetrates through the card hole opened on the surface of the plastic sheet. The threaded fastening cover is threadedly connected to the end of the threaded column extending out.

[0005] Preferably, the thickness of the plastic sheet is one-half of the thickness of the paper frame, and the threaded fastening cover is in pressing contact with the plastic sheet.

[0006] Preferably, the connecting component further includes a telescopic rod and a telescopic groove. The T-shaped telescopic rod is fixed on one side of the bottom end of the connecting piece and is slidably inserted into the telescopic groove opened inside the plastic strip.

[0007] Preferably, the connecting component further includes a spring. The spring is sleeved on the outer surface of the telescopic rod, and both ends are respectively abutted against the inner end of the telescopic rod and the inner wall of the telescopic groove.

[0008] Preferably, limiting strips are symmetrically fixed on the surface of the bottom plate, and limiting grooves adapted to the limiting strips are provided at both bottom ends of the paper frame.

[0009] Preferably, a top cover is provided on the top of the paper frame, and the inner surface of the top cover matches the outer surface of the paper frame.

[0010] Preferably, clamping strips are symmetrically fixed on the inner side of the top cover, and clamping grooves adapted to the clamping strips are symmetrically provided at both top ends of the paper frame.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Through the designed paper frame and bottom plate, a box-shaped structure can be formed. If the paper box needs to be folded and stored, the fixation between the paper frame and the bottom plate can be released by using the connecting component first, and then the bottom plate can be folded and turned over. At this time, the paper frame is a rectangular frame structure with both upper and lower ends open. Also, because it is made of paper, the paper frame can be folded and stored along the four edges. Moreover, the folding operation is simple and fast. If the paper box needs to be used later, only need to restore the paper frame to the rectangular frame structure, then turn over the bottom plate, use the connecting component to fix the bottom plate to the bottom of the paper frame again, and limit the paper frame to form a box body structure again. Through the above structure, it is beneficial to repeatedly fold and use the paper box. Description of the Drawings
