Description

Reinforced packing box

Technical Field

The utility model relates to a packing carton technical field especially relates to a strenghthened type packing carton.

Background

At present, the conventional small-sized packing box is generally made by folding corrugated paper or corrugated paper covered with kraft paper, the conventional paper box is generally formed by directly folding a complete multi-crease paper board, inserting, connecting and fixing the paper board, binding and connecting a plurality of paper boards at overlapped positions by using a binding machine to form a corrugated paper box with the periphery connected and sealed, then folding and sealing the upper bottom surface and the lower bottom surface, and sticking the upper bottom surface and the lower bottom surface into a complete box by using adhesive tapes. The existing packing box is generally blanked into a piece of paper and is formed by folding edges, and the easily damaged part of the packing box is generally at a corner. Particularly when dropped, the corners are more susceptible to damage. For example, in order to improve the anti-falling and anti-breakage capability, the quality of the kraft paper needs to be improved, the gram number of the corrugated paper needs to be increased, or a multi-layer structure needs to be adopted, so that the manufacturing cost is high, the total volume is increased, and the appearance is influenced.

The conventional box has the advantages that the edge of the vertical packaging box wall is not provided with the reinforcing ribs, the strength is low, and when the box is impacted, the folded edge is easy to bend and damage, so that stronger protection is difficult to achieve; for the packing box that the junction was bound with the book-binding machine, the closure is relatively poor to binding the nail and exposing outside, not only unsightly, if binding the nail and expand by the atress, still can hang the article around the ring, also probably prick the conveyer, if pack be the particulate matter, because there is the gap between the cardboard at the position of binding, easily reveal.

Based on this, the utility model designs a strenghthened type packing carton to solve above-mentioned problem.
