Sealed packaging box

Abstract

The utility model relates to the field of packaging boxes, in particular to a sealing packaging box which comprises a box cover assembly and a box body assembly movably connected to the box cover assembly. The box cover assembly comprises a sealing box cover movably connected to the box body assembly, an auxiliary assembly connected to the sealing box cover, a buckle ring connected to the sealing box cover, a positioning pressing ring connected to the buckle ring and a limiting ring connected to the positioning pressing ring. The box body assembly comprises a connecting box body movably connected to the sealing box cover, a clamping ring connected to the connecting box body, a positioning ring connected to the clamping ring and an outer protection ring connected to the clamping ring. The box body assembly and the sealing box cover are connected through the positioning pressing ring and the clamping ring which are in interference fit, and meanwhile the box body assembly and the sealing box cover need to be separated with large force through the arrangement of the limiting ring and the positioning ring when the box body assembly and the sealing box cover are separated. Therefore, the sealing performance of the whole sealed packaging box can be improved to a certain extent.

Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and more particularly to a sealed packaging box. Background Technology

[0002] In the modern product packaging industry, sealed packaging boxes are widely used in food, pharmaceuticals, cosmetics, and electronics. Their core function is to protect the contents through a reliable sealing structure, such as preventing moisture, dust, oxidation, and tampering. As consumers' requirements for product safety and shelf life continue to increase, the sealing performance of sealed packaging boxes is receiving increasing attention.

[0003] While pursuing high sealing performance, traditional sealing designs generally have a significant drawback: they are difficult to open with one hand. This problem is even more pronounced for the elderly or users with weaker hand strength. In existing technologies, some packaging attempts to improve ease of opening by adding structures such as easy-tear lines and opening handles. However, the design of easy-tear lines may compromise the overall sealing performance, thereby affecting the sealing performance of the entire packaging box. Utility Model Content

[0004] To overcome the problem that existing sealed packaging boxes inevitably make it difficult for elderly people or users with weak hand strength to open the box with one hand due to the box's sealing performance, thus affecting the convenience of use.

[0005] The technical solution of this utility model is: a sealed packaging box includes a lid assembly and a box body assembly movably connected to the lid assembly;

[0006] The lid assembly includes a sealing lid movably connected to the body assembly, an auxiliary component connected to the sealing lid, a snap ring connected to the sealing lid, a positioning ring connected to the snap ring, and a limiting ring connected to the positioning ring.

[0007] The box assembly includes a connecting box body movably connected to the sealing box cover, a locking ring connected to the connecting box body, a positioning ring connected to the locking ring, an outer protective ring connected to the locking ring, several support slots formed on the connecting box body, and an opening head connected to the outer protective ring.

[0008] Preferably, the auxiliary component includes a fixing rib connected to the sealing box cover, an exhaust head connected to the lower end face of the sealing box cover, and an exhaust hole opened on the exhaust head. The exhaust hole passes through the exhaust head and the sealing box cover. Several fixing ribs are provided and distributed at the four corners of the sealing box cover.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model uses an interference fit positioning pressure ring and a locking ring to connect the box body component and the sealed box lid. At the same time, the setting of the limiting ring and the positioning ring makes it necessary to use a larger force to separate the box body component and the sealed box lid, thereby improving the sealing performance of the entire sealed packaging box to a certain extent.

[0011] 2. This utility model bends the end of the outer protective ring outward and extends it to form an annular box opening. By pressing down the opening head, the opening head deforms on the outer protective ring, allowing the sealed packaging box to be opened quickly. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] A sealed packaging box, according to Figures 1-4 As shown, it includes a lid assembly 1 and a box body assembly 2 movably connected to the lid assembly 1;

[0019] The lid assembly 1 includes a sealing lid 101 movably connected to the body assembly 2, an auxiliary component connected to the sealing lid 101, a snap ring 105 connected to the sealing lid 101, a positioning ring 106 connected to the snap ring 105, and a limiting ring 107 connected to the positioning ring 106.

[0020] The box assembly 2 includes a connecting box body 201 movably connected to the sealing box cover 101, a locking ring 203 connected to the connecting box body 201, a positioning ring 204 connected to the locking ring 203, an outer protective ring 205 connected to the locking ring 203, a plurality of support grooves 202 formed on the connecting box body 201, and an opening head 206 connected to the outer protective ring 205.

[0021] It should be noted that the end of the outer protective ring 205 is bent outward and extends to form a ring-shaped box opening. By pressing down on the opening head 206, the opening head 206 deforms on the outer protective ring 205, which enables the sealed packaging box to be opened quickly.

[0022] according to Figures 2-3 As shown, the auxiliary components include a fixing rib 102 connected to the sealing box cover 101, an exhaust head 104 connected to the lower end face of the sealing box cover 101, and an exhaust hole 103 opened on the exhaust head 104. The exhaust hole 103 passes through the exhaust head 104 and the sealing box cover 101. Several fixing ribs 102 are provided and distributed at the four corners of the sealing box cover 101.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
