In the description of this utility model, it should be understood that if there are descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationships, the orientation description may be based on the orientation or positional relationships shown in the accompanying drawings, only for the convenience of describing this utility model and simplifying the description, and not to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, where a quantity is mentioned, "several" means one or more, "more than" means two or more, "greater than," "less than," or "exceeding" are understood to exclude the stated number, while "above," "below," or "within" are understood to include the stated number. The use of "first" or "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the quantity of indicated technical features, or the order of the indicated technical features. In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of these terms in this utility model based on the specific content of the technical solution. As shown in Figures 1 and 2, this utility model discloses an easy-tear structure for a food packaging box, including a box body 1 and a box cover 2 covering the box body 1. One end of the box cover 2 is connected to the box body 1, and the other end of the box cover 2 is an open end. The open end of the box cover 2 is provided with a front cover plate 21. The lower end of the front cover plate 21 is provided with an outwardly extending tongue piece 22. The front end of the box body 1 is provided with a limiting slot 11 adapted to the tongue piece 22. The front cover plate 21 is provided with an easy-tear line and a semi-circular handle position 211 located on the upper end of the tongue piece 22. The easy-tear line includes a front left half tangent line 212 and a front right half tangent line 213 extending from both ends of the semi-circular handle position 211 to the left and right sides of the tongue piece 22, respectively. The box body is also provided with an avoidance through hole 2112 at the position corresponding to the semi-circular handle position. When it is necessary to quickly open the packaging box, you can first press the semi-circular handle 211 and then pull it outward. This will cause the left half tangent 212 and the right half tangent 213 on the front to be torn apart, thereby separating the front cover 21 from the tongue 22. In this way, the box cover 2 can be opened directly without pulling out the tongue 22, making the operation more convenient and faster. The clearance through hole 2112 is used to avoid the semi-circular handle 211 after pressing, so as to facilitate the inward pressing and downward pulling of the semi-circular handle 211. The clearance through hole 2112 can be a circular or elliptical structure.In this invention, the easy-tear line further includes a reverse left half-cut line 214 and a reverse right half-cut line 215, which are parallel to the front left half-cut line 212 and the front right half-cut line 213, and respectively located at the lower ends of the front left half-cut line 212 and the front right half-cut line 213. The lower ends of the reverse left half-cut line 214 and the reverse right half-cut line 215 are respectively located on the left and right sides of the insert tab 22. This further ensures the easy-tear line can be torn smoothly and guides the tearing. In this invention, the distance between the front left half-cut line 212 and the reverse left half-cut line 214 is 3.5-5.5 mm. This ensures the stability of the lid 2 and the continuity during tearing. In this invention, the diameter of the semi-circular handle 211 is 15-20 mm. This facilitates hand operation. In this invention, the semi-circular handle 211 is provided with a semi-circular interrupted full tangent line 2111 (as shown in Figures 1 and 2), meaning that some points are connected together, while the rest are through cuts. This not only ensures that the semi-circular handle 211 will not open during normal use, but also allows for pressing the semi-circular handle 211 first and then pulling it outwards. In this invention, the left half tangent line 212 and the right half tangent line 213 on the front are both straight half tangent lines, which penetrate halfway. This not only ensures the overall stability when unopened, but also makes it easy to tear open the lid 2 and provides a guiding function. The easy-tear line on the lid 2 in this invention enables quick disassembly of the lid 2, greatly reducing the time spent unpacking and making unpacking more convenient and faster. The above description is a further detailed explanation of this invention in conjunction with specific preferred embodiments, and it should not be considered that the specific implementation of this invention is limited to these descriptions. For those skilled in the art to which this utility model pertains, various simple deductions or substitutions can be made without departing from the concept of this utility model, and all such modifications and substitutions should be considered within the protection scope of this utility model. 100002 2010.2 3 HK 30135229 A Claim 1.
