Description

A kind of folded cardboard packaging box

technical field

The utility model relates to the technical field of folding cardboard boxes, in particular to a folding cardboard packaging box of split type.

Background technique

In large supermarkets and fruit stores, larger fruits such as grapefruit, cantaloupe, and papaya are usually packaged in paper bags, plastic bags, or foam sleeves. These packaging materials are relatively soft, and the shape of the fruit will be deformed after packaging. In this way, the packaged fruit is not easy to place, it is easy to fall and break, and it is not convenient for customers to store it after buying it back. In addition, such packages have different shapes and lack aesthetic feeling, and look unattractive when used as gifts, which cannot enhance customers' desire to buy.

At present, the most common cuboid cardboard folding packaging box includes four side panels that surround a square tube. The upper and lower sides of the four side panels extend respectively from the upper cover and the lower cover, and the four upper covers are folded inward and closed. The first and the last are overlapped and seized sequentially to form a cover, and the four lower cover panels are folded inwards and sequentially overlapped and seized to form the back cover. The area of the overlapping cardboards of this kind of packaging boxes is relatively large, which is a waste of materials, and it is not convenient for customers to take out the fruits after they buy them back.

Contents of the invention

In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a folded cardboard packaging box of split type.

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

A kind of foldable cardboard packaging box of split type. The aforementioned packaging box is made by folding a single piece of cardboard. The large end of the large end is buckled on the upper opening of the base, and the upper cover is divided into two half-covers with a right-angled trapezoidal section along the height of its isosceles trapezoidal section. The base includes a square bottom plate, two opposite square first One side panel and two opposite square second side panels, each half-cover includes a square straight waist panel, a square oblique waist panel, a square upper bottom panel, a square lower bottom panel and two right-angled trapezoidal end panels; In this state, the two opposite sides of the bottom plate overlap with one side of the two first side panels respectively, and the opposite sides of the two first side panels coincide with the lower sides of the two inclined waist panels respectively. The upper sides of the sloping waist boards overlap with one side of the two upper bottom boards, the opposite sides of the two upper bottom boards overlap with the upper sides of the two straight waist boards respectively, and the lower sides of the two straight waist boards respectively coincide with the sides of the two lower bottom boards. One side overlaps, the straight waists of the four end panels coincide with the two opposite sides of the two straight waists respectively, and the other two opposite sides of the bottom panel coincide with one side of the two second side panels respectively , the bottom edge of the end plate extends outwards from the first connecting plate, the opposite side of the lower bottom plate extends outwards from the second connecting plate, and the connecting edge of the end plate and the first connecting plate is provided with a first socket , the opposite side of the second side plate extends outwards from the first inserting plate, a tapered hole is opened on the straight waist plate, an arc-shaped hole is opened on the lower bottom plate, the chord side of the arc-shaped hole and the tapered The bottom edge of the hole is butted at the connecting edge of the straight waist plate and the lower bottom plate; in the folded 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, and the two straight waist plates are attached to each other , the end plate is perpendicular to the straight waist plate and the inclined waist plate, 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 same side in the first jack.
