Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and in particular to a packaging box lid and a packaging box. Background Technology

[0002] When packaging fruit, especially thin-skinned fruits like strawberries and figs, if the fruit isn't secured after being placed inside the box, it can be damaged by collisions during transportation and sales, accelerating spoilage. To address this issue, two solutions are currently available: one is to place the fruit inside the box and cover it with plastic wrap to prevent movement and bruising. The other method involves directly attaching plastic wrap to the bottom of the lid, ensuring the fruit stays in place after closing, thus extending shelf life. However, both methods have drawbacks. The former is inconvenient during packaging, while the latter requires inserting a retaining strip along the inside edge of the box opening to secure the lid. Closing the lid this way requires pressing each edge of the lid under the retaining strip, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a packaging box lid and a packaging box, which can directly snap the bottom-filmed packaging box lid onto the box body, simplifying operation and improving packaging efficiency. This utility model provides the following technical solution: A packaging box lid includes a top cover and a film, characterized in that: a first downward protrusion is provided at the four edges of the top cover; a second protrusion is provided inside the first protrusion, and a downward-opening groove is formed between the first protrusion and the second protrusion; the film is pressed onto the outer side wall, inner side wall, or lower bottom surface of the second protrusion, and a reserved space is formed between the lower surface of the top cover and the upper surface of the film.

[0004] Using the above technical solution, the film can be pressed onto the outer side wall, inner side wall, or bottom surface of the second protrusion. A downward-opening groove is formed between the second protrusion and the first protrusion on the outer side of the second protrusion. When the box lid is placed on the box body, the groove between the first protrusion and the second protrusion can be inserted into the box body fold edge at the opening edge of the box body, so that the box lid covered with the film can be directly closed on the box body.

[0005] As a further improvement of this utility model, the top cover includes a top cover body, the second protrusion is a top cover side wall extending from the periphery of the top cover body toward the box body, and the bottom of the top cover side wall is also provided with a horizontal folded edge extending outward from its lower surface; the first protrusion is a folded edge that first folds upward from the outer edge of the horizontal folded edge and then folds downward toward the outside of the box cover.

[0006] By adopting the above technical solution, an outwardly extending horizontal fold is provided at the bottom of the side wall of the top cover, which can not only enhance the structural strength of the top cover, but also facilitate film covering. By setting an upward and then downward fold on the outside of the horizontal fold, a downward-opening groove is formed between the fold away from the side wall and the fold close to the side wall, which can be fastened to the box body.

The box body includes a box bottom and box body sidewalls extending from the box bottom around the box lid. The top of the box body sidewalls is provided with a box body folded downward toward the inner / outer side of the box, and there is a gap between the box body folded edge and the box body sidewalls.

[0014] Using the above technical solution, there is a gap between the box body fold and the box body side wall, which allows the box body fold to have elastic space. After the box body fold is inserted into the groove of the top cover, the box body fold can spring open and make closer contact with the side wall of the groove, making the engagement more secure.
