Description

Packaging cut-parts that triangle broadside was strengthened

Technical Field

The utility model belongs to the technical field of the carton packing and specifically relates to a packing cut-parts that triangle broadside was strengthened is related to.

Background

Packaging cartons and paper trays are very common in daily life and production, most commonly rectangular corrugated paper cartons. The carton or the tray can protect packaged articles in the transportation process, so the strength of the carton is particularly critical, particularly, when the articles are stored or transported frequently, the articles need to be stacked and placed in order to save space, and in order to prevent the articles from being damaged, the carton or the paper tray is required to have better compressive strength so as to ensure the supporting performance of the carton or the paper tray. In order to have good compressive strength and support performance, most of cartons or paper trays increase the compressive strength of carton or paper tray through externally adding the cornerite, but, the risk that drops exists in the additional cornerite, and the intensity of the back carton that drops receives the influence, and in addition, the carton need install the cornerite additional after fold forming again, makes the preparation of carton more complicated.

Chinese patent application publication No. CN208813823U, the grant announcement day is 2019 year 05 month 03 day, the name is "a corrugated carton with angle bead" discloses a corrugated carton with angle bead, including the carton main part, carton lid and handle, the bottom fixedly connected with carton box of carton main part, there is the handle in the middle part of the both sides through connection of carton box, the positive fixedly connected with label draw-in groove of carton main part, the top nested connection of carton box has the carton lid, the fixed surface of carton main part is connected with corrugated container board, the dampproofing base of bottom fixedly connected with of carton main part, the upper and lower four corners swing joint of carton main part has the angle bead. The utility model discloses a protect the carton main part through eight angles with the carton main part, but protect the carton through the method of swing joint angle bead, the angle bead still has the risk that drops, and installs the angle bead additional and make the process of carton preparation more loaded down with trivial details.

Disclosure of Invention

The utility model discloses an it is poor to overcome prior art carton compressive strength, and plus cornerite exists the risk of droing and make loaded down with trivial details not enough, provides the packing cut-parts that triangle broadside was strengthened, and the carton compressive strength who forms after folding is high, and the carton of formation can be directly by cut-parts folding forming, the simplification process.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a packing cut-parts that triangle broadside was strengthened, includes the bottom plate, one of them a pair of opposite side of bottom plate respectively is connected with a curb plate, and another is respectively connected with a panel to the opposite side, be connected with two symmetrical arrangement on the outside limit of curb plate at the triangle broadside at its both ends, the triangle broadside include with the base of the outside limit coincidence of curb plate, and, with the outside that the outside limit of curb plate meets, be connected with on the outside of triangle broadside and strengthen the panel, strengthen and realize being connected with fixed knot structure between the panel of panel and homonymy.
