Description

Split type hard board folding packaging box

Technical Field

The utility model relates to a folding carton technical field, more specifically relate to a to open hard board folding packaging box.

Background

In large supermarkets and fruit shops, larger fruits such as grapefruits, hami melons and pawpaw are usually packaged by paper bags, plastic bags or foam sleeves and the like. These packaging materials are softer, can depend on the shape deformation of fruit after the packing, and the fruit after the packing is not convenient for put like this, rolls easily and falls to break, and customer also is not convenient for deposit after buying back. In addition, the shape of the packaged product is different, the packaged product is not beautiful, and the packaged product is not beautiful when used as a gift and cannot promote the purchasing desire of customers.

At present, the most common cuboid-shaped hard cardboard folding packaging box comprises four side plates which are enclosed into a square cylinder, wherein an upper cover plate and a lower cover plate are respectively extended from the upper edge and the lower edge of the four side plates, the four upper cover plates are inwards folded and are sequentially overlapped and fastened end to form a sealing cover, and the four lower cover plates are inwards folded and are sequentially overlapped and fastened end to form a sealing bottom. The area of the mutually overlapped hardboards of the packing box is larger, which wastes materials and is not convenient for taking out fruits after customers buy the packing box.

Disclosure of Invention

The utility model provides an overcome not enough among the above-mentioned prior art, provide a to open hard board folding packaging box.

The utility model discloses a following technical scheme realizes above-mentioned purpose.

A split type cardboard folding packaging box is formed by folding a single cardboard, and comprises a square box-shaped base part with an upper opening and an upper cover part with an isosceles trapezoid cross section, wherein the large end of the upper cover part is buckled on the upper opening of the base part, the upper cover part is divided into two half cover parts with right trapezoid cross sections along the high height of the isosceles trapezoid cross section, the base part comprises a square bottom plate, two opposite square first side plates and two opposite square second side plates, and each half cover part comprises a square straight waist plate, a square inclined waist plate, a square upper bottom plate, a square lower bottom plate and two right trapezoid end plates; in an unfolded state, two opposite side edges of the bottom plate are respectively superposed with one side edge of the two first side plates, the other opposite side edges of the two first side plates are respectively superposed with the lower edges of the two inclined waist plates, the upper edges of the two inclined waist plates are respectively superposed with one side edge of the two upper bottom plates, the other opposite side edges of the two upper bottom plates are respectively superposed with the upper edges of the two straight waist plates, the lower edges of the two straight waist plates are respectively superposed with one side edge of the two lower bottom plates, the straight waist edges of the four end plates are respectively superposed with the two opposite side edges of the two straight waist plates, the other two opposite side edges of the bottom plate are respectively superposed with one side edge of the two second side plates, the bottom edges of the end plates outwards extend out to form a first connecting plate, the other opposite side edges of the lower bottom plates outwards extend out to form a second connecting plate, the connecting edges of the end plates and the first connecting plates are provided with first inserting holes, and, the straight waist plate is provided with a conical hole, the lower bottom plate is provided with an arc-shaped hole, and the chord edge of the arc-shaped hole is butted with the bottom edge of the conical hole at the connecting edge of the straight waist plate and the lower bottom plate; under a folding state, the first side plate and the second side plate are perpendicular to the bottom plate, the upper bottom plate and the lower bottom plate are parallel to the bottom plate, the two straight waist plates are attached to each other, the end plates are perpendicular to the straight waist plates and the inclined waist plates, the two second connecting plates are respectively attached to the two inclined waist plates, the four first connecting plates are respectively attached to the two lower bottom plates, and the first inserting plates are respectively inserted into the first inserting holes in the same side.
