Description

Technical Field

[0001] This utility model particularly relates to a rotating cover assembly and its packaging box. Background Technology

[0002] To enhance interactivity, a common design is to include a rotatable decorative cover on the box lid. Users can rotate the cover to interact with it, improving the user experience. However, this design has several drawbacks: To achieve rotation, a through-hole needs to be created in the lid to accommodate a pivot. A common structure uses a cantilever support, where the pivot is fixed at only one end. This structure inherently suffers from insufficient rigidity; when the user repeatedly rotates the cover, the pivot and its support are prone to wobbling due to the force applied. This is especially problematic for packaging boxes of food, pharmaceuticals, and other products with high moisture resistance requirements, where sealing performance is crucial. Furthermore, creating a through-hole for the rotation mechanism compromises the lid's integrity, creating a potential channel for moisture intrusion. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a rotating cover assembly and its packaging box.

[0004] A rotating cover assembly includes an upper cover, characterized in that: the upper cover has a through hole and mounting portions are provided on opposite sides of the through hole; opposite ends of a mounting plate are rigidly fixedly connected to the mounting portions; an upwardly extending positioning post is fixedly provided on the mounting plate; and a decorative cover is rotatably fitted onto the positioning post via a rotating connection assembly.

[0005] Preferably, the rotating connection assembly is a rolling bearing.

[0006] Preferably, the mounting part is a card interface provided on the upper cover, and the mounting plate has card ears at opposite ends that engage with the card interface.

[0007] Preferably, the decorative cover has a circular cross-section and is spherically convex outward.

[0008] A packaging box includes a box body and a rotating cover assembly as described above. The box body has a receiving cavity, and the cover assembly is rotatably disposed on the box body and has a closed state covering the receiving cavity and an open state rotating relative to the box body.

[0009] Preferably, a sealing gasket is sandwiched between the cover assembly and the box body; the sealing gasket is tightly fitted to the inner surface of the upper cover in the closed state and completely covers the through hole and the mounting plate mounted thereon.

[0010] Preferably, the cover assembly is rotatably connected to the box body via a hinge or pivot structure.

[0011] Preferably, the accommodating cavity is provided with an inner liner for holding the contents, and a sealing edge is formed on the top of the inner liner; when the cover assembly is in the closed state, the sealing gasket is compressed between the upper cover and the box body, and at the same time comes into close contact with the sealing edge of the inner liner, thereby forming a seal for the contents together with the inner liner.

[0012] Preferably, the inner liner and the sealing gasket are made of the same food-grade elastic sealing material.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses an mounting plate as a carrier, and its opposite ends are rigidly fixedly connected to the mounting part of the upper cover. This is equivalent to providing a "two-point support bridge" structure for the positioning post that spans the through hole.

[0021] A rotating cover assembly includes an upper cover 1, characterized in that: a through hole 11 is provided on the upper cover 1 and mounting portions 12 are provided on opposite sides of the through hole 11; opposite ends of a mounting plate 2 are rigidly fixedly connected to the mounting portions 12; an upwardly extending positioning post 22 is fixedly provided on the mounting plate 2; and a decorative cover 3 is rotatably fitted onto the positioning post 22 via a rotating connection assembly.

[0022] Furthermore, the rotating connection assembly is a rolling bearing 4.

[0023] Furthermore, the mounting part 12 is a card interface provided on the upper cover 1, and the mounting plate 2 has card ears 21 at opposite ends that engage with the card interface.

[0024] Furthermore, the decorative cover 3 has a circular cross-section and is spherically convex.

[0025] A packaging box includes a box body 5 and a rotating cover assembly as described above. The box body 5 has an accommodating cavity. The cover assembly is rotatably disposed on the box body 5 and has a closed state covering the accommodating cavity and an open state rotating relative to the box body 5.

[0026] Furthermore, a sealing gasket 6 is sandwiched between the cover assembly and the box body 5; the sealing gasket 6 is tightly fitted to the inner surface of the upper cover 1 when the cover is closed, and completely covers the through hole 11 and the mounting plate 2 installed thereon.

[0027] Furthermore, the cover assembly is rotatably connected to the box 5 via a hinge or pivot structure.

[0028] Furthermore, the accommodating cavity is provided with an inner liner 7 for holding the contents, and a sealing edge is formed on the top of the inner liner 7; when the cover assembly is in the closed state, the sealing gasket 6 is compressed between the upper cover 1 and the box body 5, and at the same time comes into close contact with the sealing edge of the inner liner 7, thereby forming a seal for the contents together with the inner liner 7.

[0029] Furthermore, the inner liner 7 and the sealing gasket 6 are made of the same food-grade elastic sealing material.

[0030] Example 1: Cover Assembly See Figure 1 and Figure 2 The upper cover 1 is a plastic plate with a circular through hole 11 in its center. On opposite sides of the through hole 11, snap-fit ​​interfaces, serving as mounting parts 12, are integrally injection-molded with the upper cover 1. A mounting plate 2 is made of plastic (such as ABS) and is roughly elongated, with downward-protruding snap-fit ​​ears 21 at its longitudinal ends. During assembly, the snap-fit ​​ears 21 at both ends of the mounting plate 2 are aligned with the snap-fit ​​interfaces of the upper cover 1, and pressure is applied vertically until the snap-fit ​​ears 21 snap into the snap-fit ​​interfaces. At this point, there is no rotational or translational freedom between the mounting plate 2 and the upper cover 1, forming a rigid fixed connection. The middle part of the mounting plate 2 is integrally injection-molded with a positioning post 22, which extends vertically upwards, its axis coinciding with the central axis of the through hole 11. A decorative cover 3 is hemispherical, and a deep groove ball bearing 4 is fixed to the top of its inner cavity via a slot or other means. During assembly, the inner ring of the bearing 4 is pressed into the locating post 22 with an interference fit until a small gap remains between the bottom of the decorative cover 3 and the surface of the upper cover 1. Thus, the decorative cover 3 can rotate smoothly and stably 360 degrees relative to the fixed locating post 22 and the upper cover 1 via the bearing 4.

[0031] See Figure 3 and Figure 4 A packaging box includes a box body 5 and a lid assembly as described in Embodiment 1. The box body 5 has a receiving cavity for containing items requiring sealing and moisture protection, such as candy or pills. The lid assembly is rotatably connected to the box body 5 via a hinge structure (i.e., a pivot structure) integrally formed with the upper lid 1 and the box body 5, allowing the lid assembly to have a closed state covering the receiving cavity and an open state rotating about the hinge axis.

[0032] Based on the above technical solution, to achieve reliable moisture-proof function, a sealing gasket 6 is provided between the lid assembly and the lid surface of the box 5. This sealing gasket 6 can be made of white, soft, closed-cell silicone foam material that meets food safety standards. The inner surface of the upper lid 1, i.e., the side facing the receiving cavity of the box 5, has a recessed mounting groove 13. The shape and size of the sealing gasket 6 are adapted to the mounting groove 13 and are embedded and fixed within it. When the lid assembly is closed, the upper opening edge of the box 5 directly presses against the sealing gasket 6, compressing and deforming it within the mounting groove 13, thereby forming a tight seal between the upper lid 1 and the box 5. The dimensions of the sealing gasket 6 are precisely designed to ensure that, in its compressed state, the projection of its covered area completely covers the through hole 11 and the mounting plate 2 below.

[0033] Based on the above technical solution, the inner liner 7 is disposed within the receiving cavity of the box body 5, and its shape matches the receiving cavity, for directly holding contents such as candy and pills. The top edge of the inner liner 7 extends horizontally outward to form an annular sealing edge 71. When the lid assembly is in the closed state, the sealing gasket 6 is compressed between the mounting groove 13 of the upper lid body 1 and the sealing edge 71 of the inner liner 7. Thus, the lower surface of the sealing gasket 6 is tightly joined with the upper surface of the sealing edge 71, forming the first main sealing interface; at the same time, the side of the sealing gasket 6 may come into contact with the groove wall of the mounting groove 13, forming an auxiliary seal. This design achieves a direct and continuous sealing path from the lid body to the inner liner, blocking the possibility of moisture entering the interior of the inner liner 7.

[0034] This utility model uses an mounting plate 2 as a carrier, and its opposite ends are rigidly fixedly connected to the mounting part 12 of the upper cover 1. This is equivalent to providing a "two-point support bridge" structure for the positioning post 22 that spans the through hole 11. This design fundamentally solves the inherent rigidity deficiency of cantilever support, and effectively avoids the phenomenon of the decorative cover 3 shaking during rotation when the user rotates it.

[0035] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
