[0031] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the protection scope of the present application. Embodiment 1

[0032] Referring to Figures 1-4 As shown in the figure, a multi-cell paper lunch box with concave / convex frame includes a box body 10 and a top cover 3.

[0033] The box body 10 is made by hot pressing forming, and the edge of the box body is provided with a concave frame; one or more than one partition strip 4 is attached in the box body 10;

[0034] The top cover 3 is made by hot-pressing forming, and the edge of the top cover is provided with a convex frame 31 which is matchedly buckled on the concave frame.

[0035] Since the edge of the box body is provided with the concave frame and the edge of the top cover is provided with the convex frame which is matchedly buckled on the concave frame, the concave frame of the box body and the convex frame of the top cover can be directly buckled to realize firm covering, without setting the overhanging and tongue-shaped protrusion; and the concave frame and the convex frame also increase the edge strength of the box body and the top cover.

[0036] As a specific embodiment, the box body comprises a first sheet and a second sheet.

[0037] The first sheet is made by hot-pressing forming into a first half box body 1 of a cuboid without a top cover; the two sides of the short edge of the first half box body have a first concave frame 11 which has an extension 12;

[0038] The second sheet is made by hot-pressing forming into a second half box body 2 of a cuboid without a top cover, and the two sides of the short edge of the second half box body have a second concave frame 21 which is hot-pressed and fixed after transversely overlapping with the extension 12; one side of the long edge of the second half box body 2 is hot-pressed and fixed after longitudinally overlapping with one side of the long edge of the first half box body 1, to form the box body.

[0039] In this way, in the first aspect, since the second concave frame is hot-pressed and fixed after transversely overlapping with the extension; one side of the long edge of the second half box body is hot-pressed and fixed after longitudinally overlapping with one side of the long edge of the first half box body, to form the box body, so that the overlapping in the transverse direction and the longitudinal direction can improve the connection strength of the box body.

[0040] In the second aspect, since the first half box body is hot-pressed and formed, and the second half box body is also hot-pressed and formed, the hot-pressing forming is to extrude and heat-form the sheet of paper material at the edge into the required shape of the half box body, so as to form the container with better structural strength and sealing performance.

[0041] As a specific embodiment, one end of the top cover is rotatably connected with one end of the second half box body through a crease. In this way, the top cover and the second sheet can be integrally made of one sheet.

[0042] As a specific embodiment, the other side of the long edge of the first half box body has a third concave frame 13 which is integrally connected with the inner side 14 and the outer side 15 of the first concave frame 11 through arc-shaped transition.

[0043] In one specific implementation, the second half of the box 2 is provided with partitions 4, dividing the second half of the box 2 into several compartments. Specifically, the second half of the box has two partitions, dividing the second half of the box into three compartments. These partitions are attached independently. That is, the box body is first thermoformed, and then the partitions are attached independently. This makes it easy to produce the lid and box body, and also easy to assemble the partitions. Example 2

[0044] Referring to Example 1, the difference from Example 1 is that... Figure 5 As shown, in this embodiment, the outer side 15 of the third concave frame and the first concave frame are connected by an arc transition, and their inner sides 14 are connected by a straight line. Example 3

[0045] Referring to Example 1, the difference from Example 1 is that... Figure 6 As shown, in this embodiment, the two partition strips 4 are connected as one piece and then attached to the box body as a whole. Example 4

[0046] Referring to Embodiment 1, the difference from Embodiment 1 is that the first concave border, the second concave border, and the third concave border of Embodiment 1 are replaced with the first convex border, the second convex border, and the third convex border; and the convex border of Embodiment 1 is replaced with the concave border accordingly. Example 5

[0047] Referring to Embodiment 1, unlike Embodiment 1, the second half of the box in this embodiment does not have a partition strip attached, but the first half of the box has a partition strip to divide the first half of the box into several compartments. Example 6

[0048] Referring to Example 1, based on Example 1, not only are partitions planted in the second half of the box, but partitions are also provided in the first half of the box to divide the first half of the box into several compartments.

[0049] It should be noted that thermoforming is a mature technology in the field of paper containers. Thermoforming is a process that shapes materials under heat and pressure.

[0050] This utility model discloses a multi-compartment paper lunch box with concave / convex borders, which is a multi-compartment paper lunch box with concave and convex borders that work together with a snap fastener. When the edge of the box body has a concave border, the edge of the top cover has a corresponding convex border; when the edge of the box body has a convex border, the edge of the top cover has a corresponding concave border.

[0051] The series of detailed descriptions listed above are only specific descriptions for the feasible embodiments of the present application, and are not used to limit the protection scope of the present application. Any equivalent embodiments or changes made without departing from the spirit of the present application should be included in the protection scope of the present application.
