Further, as shown in fig. 8 and 9, the outer groove wall of the second outer fitting groove is provided with a pull ring 2231 and a handle 2232, respectively. The outer groove wall of the second outer engagement groove can be easily deformed by pulling it outward by the handle 2232 or the pull ring 2231 to expose the outer groove wall of the first outer engagement groove, thereby facilitating the opening of the container lid.
Further, as shown in fig. 10, the outer groove wall of the second outer fitting groove is provided with a first cut 2233 and a second cut 2234 which are vertically distributed, and the depth of the first cut 2233 and the second cut 2234 is slightly smaller than the wall thickness of the outer groove wall of the second outer fitting groove. The part of the outer groove wall of the second outer matching groove between the two notches can be torn off along the vertical part or the whole part through the two notches, so that the outer groove wall of the first outer matching groove is exposed, and the container cover is convenient to open.
Further, as shown in fig. 11, an upper edge of the outer groove wall of the second outer engaging groove is provided with a notch, and the outer groove wall of the second outer engaging groove is provided with a thin-walled region 2235 corresponding to the notch in the vertical direction. The thin-walled region 2235 is torn off partially or completely vertically through this gap, exposing the outer wall of the first outer mating groove, facilitating opening of the container lid.
In each embodiment of the present invention, a gap may be left between the groove bottom 122 of the first external fitting groove and the groove bottom 222 of the second external fitting groove, and if the packing box is made of a material with a small deformation amount, the gap may be pried by a tool when the packing box is opened, so as to facilitate the opening of the packing box.
In each embodiment of the invention, the five anti-tripping structures can be respectively and independently arranged, and two or three or four or five anti-tripping structures can also be used in combination.
The above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it will be apparent to those skilled in the art that other variations and modifications of the present invention may be made on the basis of the above description. And are neither required nor exhaustive of all embodiments. And such obvious variations or modifications which fall within the spirit of the invention are intended to be covered by the scope of the present invention.
