[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0020] Example

[0021] like Figure 1-3As shown, this embodiment discloses a tightly covered cylindrical packaging box, comprising a box body 1 and a box cover 2, wherein the box body 1 is cylindrical and provided with a storage cavity 3 opening upward, the box cover 2 covers the storage cavity 3 and is used to cover the opening, the box cover 2 comprises a cover plate 4 and a fixing seat 5 arranged on the lower end surface of the cover plate 4, the cover plate 4 is circular plate-shaped and the outer peripheral edge of the lower end surface of the cover plate 4 abuts the upper end of the box body 1, the fixing seat 5 is annular and is embedded in the opening, the outer ring wall of the fixing seat 5 is provided with a limiting groove 6, the inner wall of the upper part of the box body 1 is provided with a card block 7 protruding radially inwardly along the box body 1, and the card block 7 is used to be clamped in the limiting groove 6. The outer ring wall of the fixing seat 5 is provided with a concave-convex pattern 8, and the concave-convex pattern 8 abuts against the inner wall of the upper part of the box body 1. By arranging a limiting groove 6 on the outer peripheral wall of the fixing seat 5 and arranging a clamping block 7 on the inner wall of the upper part of the box body 1, the limiting groove 6 matches the clamping block 7, and when the box cover 2 is closed on the top of the box body 1, the clamping block 7 is clamped in the limiting groove 6, which can prevent the box cover 2 from being rotated; by arranging a concave-convex texture 8 on the outer ring wall of the fixing seat 5, the friction between the box body 1 and the box cover 2 is increased, which can prevent the box cover 2 from falling off the box body 1 due to external force, and effectively increase the firmness of the packaging box.

[0022] The concavo-convex pattern 8 includes a plurality of convex strips arranged in sequence and spaced apart along the circumferential direction of the outer ring wall of the fixing seat 5, and a recessed portion is provided between adjacent convex strips, and the limiting groove 6 is located between the convex strips at the head end and the convex strips at the tail end. That is, the concavo-convex pattern 8 is provided in the area where the limiting groove 6 is not provided on the outer ring wall of the fixing seat 5, and the concavo-convex pattern 8 extends from one side of the limiting groove 6 to the direction away from the limiting groove 6 until it extends to the other side of the limiting groove 6, and each convex strip extends from the lower end of the fixing seat 5 to the upper end of the fixing seat 5.

[0023] In this embodiment, the diameter of the fixing seat 5 is the same as the diameter of the inner wall of the box body 1. When the box cover 2 is closed on the box body 1, the outer peripheral wall of the fixing seat 5 abuts against the inner wall of the box body 1, and the fixing seat 4 can be completely clamped on the top of the box body 1.

[0024] In this embodiment, the diameter of the cover plate 4 is the same as the diameter of the outer wall of the box body 1. When the cover plate 4 is covered on the box body 1, the cover plate 4 can completely cover the storage cavity 3.

[0025] In this embodiment, the fixing seat 5 is made of EVA sponge material. The use of EVA sponge material facilitates cutting of the concave-convex pattern 8 on the outer peripheral wall of the fixing seat 5 .

[0026] In this embodiment, the box body 1 and the box cover 2 are both made of paper material. Using paper material can not only reduce production costs, but also avoid environmental pollution.

[0027] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
