Description

Technical Field

[0001] This utility model relates to the field of food packaging box technology, specifically to a pressure-resistant food packaging box that is easy to seal. Background Technology

[0002] Currently, many food packaging boxes are made of relatively soft materials, such as the paper food packaging boxes commonly used in pastry shops. These boxes lack sufficient compression resistance, making them prone to damaging the shape of the pastries when subjected to external pressure. This reduces the appearance of the pastries and makes them difficult to carry. Furthermore, most paper food packaging boxes for pastries are individually packaged, requiring the use of paper bags when carrying multiple boxes. This additional paper bag not only wastes paper materials and is detrimental to the environment but also increases the cost of selling the food. Therefore, a pressure-resistant food packaging box that is easy to seal is proposed. Utility Model Content

[0003] The purpose of this utility model is to solve the problems that current paper food packaging boxes are prone to damage to the shape of the pastries inside when subjected to external pressure, making it difficult to carry the pastries. Furthermore, when carrying multiple food packaging boxes, paper packaging bags are still needed, which not only wastes paper materials and is not environmentally friendly, but also increases the cost of selling. This utility model provides a pressure-resistant food packaging box that is easy to seal.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A pressure-resistant food packaging box that is easy to seal includes a box body. A folding lid is fixedly installed on the side wall of the box body, and a locking mechanism is provided at one end of the folding lid. A cardboard frame is fixedly fitted on the outer side wall of the box body. Vertical locking holes are symmetrically installed on the side wall of the cardboard frame, and the vertical locking holes are matched with the locking mechanism. Horizontal locking holes are symmetrically installed on the side wall of the cardboard frame. Hook mechanisms are symmetrically installed on the lower side wall of the cardboard frame, and the hook mechanisms are matched with the horizontal locking holes.

[0006] Preferably, the positioning mechanism includes an edge sealing plate, a connecting strip is fixedly installed on one side of the edge sealing plate, and positioning paper strips are provided at both ends of the connecting strip. The middle part of the positioning paper strips is fixedly installed on the connecting strip, and two vertical positioning holes are respectively provided at both ends of the positioning paper strips.

[0007] Preferably, the cardboard frame has multiple strip openings on its side wall, and the multiple strip openings are distributed in a ring shape on the side wall of the cardboard frame.

[0008] Preferably, a reinforcing rib is fixedly installed inside the strip opening of the cardboard frame, and multiple reinforcing ribs are linearly distributed inside the strip opening.

[0009] Preferably, the hook mechanism includes a hook strip, one end of which is rotatably mounted on the side wall of the cardboard frame, and a limiting paper strip is provided on the side wall of one end of the hook strip, the middle part of which is fixedly mounted on the side wall of the hook strip.

[0010] Preferably, a metal rotating column is provided through the hook strip, and one end of the metal rotating column is provided through the cardboard frame and the box body. Both ends of the metal rotating column are provided with positioning pressure edges.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, when packaging is required, the folded cover on the box body can be flipped down to seal the open position on the box body. Then, the sealing plate is folded down, and the two ends of the connecting strip are inserted into the vertical slotting holes on both sides. Then, the slotting paper strips on both sides of the connecting strip are opened, thereby quickly sealing the packaging box. The hard paper frame on the outside of the box body can effectively improve the pressure resistance of the entire paper packaging box, thereby achieving a better protection effect for the pastries inside and reducing the probability of the food inside being squeezed and deformed.

[0013] 2. In this utility model, by rotating the hook strip on the cardboard frame of one packaging box and then inserting the hook strip into the horizontal locking hole plate on another packaging box, and then flipping open the limiting paper strip plate on the hook strip, the two packaging boxes can be effectively connected together. This allows multiple packaging boxes to be carried at once without the aid of an external packaging bag, thereby reducing the number of paper packaging bags used. This is not only beneficial to the environment, but also reduces the packaging costs of food stores. Attached Figure Description
