[0004] In order to overcome the defects of the existing technology, this utility model proposes a packaging cardboard box lid and a cardboard box.

[0005] The technical solution of this utility model is implemented as follows: a packaging cardboard box cover includes a top surface and an upper side edge. A first annular protrusion is provided on the top surface, and a second annular protrusion is provided at the edge of the top surface. The upper side edge is connected to the second annular protrusion.

[0006] In one embodiment, the upper side is provided with creases evenly distributed.

[0007] In one embodiment, the crease includes a long crease and a first short crease, which are arranged alternately.

[0008] In one embodiment, the length of the first short crease is half that of the long crease.

[0009] In one embodiment, the length of the long crease is the same as the width of the upper side.

[0010] In one embodiment, the packaging cardboard box lid also has an inner edge located inside the upper side edge, and a second short crease is provided on the inner edge.

[0011] In one embodiment, the second short crease is the same length as the first short crease.

[0012] This utility model also discloses a cardboard box, including the packaging cardboard box cover described in any of the preceding claims, and a bottom box, wherein the bottom box is composed of a bottom surface, a lower side, and a covering side, and the covering side covers the lower side.

[0013] In one embodiment, the covering side includes an inner covering surface, an outer covering surface, and a rolled edge, the lower side extending between the inner covering surface and the outer covering surface, and the rolled edge located at the lower end of the outer covering surface and abutting against the bottom surface.

[0014] The advantages of this utility model are:

[0015] (1) By setting the first annular protrusion, the cardboard box can have a larger expansion space when it is squeezed from the inside, which makes it easier for the box to remain closed.

[0016] (2) By setting a second annular protrusion, when the top surface is squeezed, there is a larger space for movement between the upper side and the top surface, so that the upper side can further press against and squeeze the lower side to avoid separation;

[0017] (3) The integrated molding process of the packaging cardboard box lid makes the product production convenient and the overall integrity good. Attached Figure Description

[0027] In the diagram, the packaging cardboard box includes a lid 1, a top surface 11, a first annular protrusion 111, a second annular protrusion 112, an upper side edge 12, a long crease 121, a first short crease 122, an inner edge 13, a second short crease 131, a bottom box 2, a bottom surface 21, a lower side edge 22, a covering side edge 23, an inner covering surface 231, an outer covering surface 232, and a rolled edge 233. Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figures 1 to 8 As shown, this utility model discloses a paper box, including a packaging cardboard box lid 1 and a bottom box 2.

[0030] like Figures 2 to 5 The packaging cardboard box lid 1 shown includes a top surface 11 and an upper side edge 12. A first annular protrusion 111 is provided on the top surface 11, and a second annular protrusion 112 is provided at the edge of the top surface 11. The upper side edge 12 is connected to the second annular protrusion 112.

[0031] Preferably, the upper side 12 is evenly provided with creases.

[0032] Preferred, such as Figure 2 and Figure 9 As shown, the crease includes a long crease 121 and a first short crease 122, which are arranged alternately.

[0033] It is understandable that when a circular piece of paper needs to be pressed, pressing the upper side 12, which is a flat ring, into a flat ring requires a certain amount of folding on the outside. Therefore, pressing creases can make the folding complete smoothly.

[0034] Preferably, the length of the first short crease 122 is half that of the long crease 121.

[0035] Preferably, the length of the long crease 121 is the same as the width of the upper side 12.

[0036] Preferably, the packaging cardboard box lid 1 also has an inner edge 13, which is located inside the upper side edge 12, and a second short crease 131 is provided on the inner edge 13.

[0037] Preferably, the second short crease 131 is the same length as the first short crease 122. The bottom box 2 consists of a bottom surface 21, a lower side 22, and a covering side 23, with the covering side 23 covering the lower side 22.

[0038] Preferably, the covering side 23 includes an inner covering surface 231, an outer covering surface 232, and a rolled edge 233. The lower side 22 extends between the inner covering surface 231 and the outer covering surface 232, and the rolled edge 233 is located at the lower end of the outer covering surface 232 and abuts against the bottom surface 21.

[0039] It is worth mentioning that the packaging cardboard box lid 1 is formed by pressing circular paper pieces in multiple steps, such as... Figure 9 As shown, the pressing step includes:

[0040] Step 1, press crease a;

[0041] Step 2: Cut into round pieces;

[0042] Step 3: Press crease b and shape it into a round cap shape;

[0043] Step 4: Press the crease c, curl the edges 233, and roll the edges to set the shape.

[0044] It is understandable that the packaging cardboard box lid 1 is formed by pressing a single piece of paper, which has a simple structure, low manufacturing cost, and is easy to promote and apply.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
