[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] like Figure 1-Figure 2 As shown, the present application provides a multi-layer blister packaging box, which is formed in one piece from a plastic material through a blister process;

[0025] The multi-layer blister packaging box comprises a box body 1, and a box cover 2 arranged above the box body 1, and a sealing edge 11 is arranged at the opening edge of the box body 1, and a sealing groove 21 adapted to the sealing edge 11 is arranged at the edge of the box cover 2, so that the box cover 2 is suitable for covering the opening of the box body 1 to open or close the box body 1;

[0026] like Figure 3 As shown, a step surface 12 is provided on one side of the sealing edge 11 of the box body 1, a lock buckle 13 is provided on the step surface 12, and a buckle groove 22 adapted to the lock buckle 13 is provided on one side of the sealing groove 21 on the box cover 2, and the buckle groove 22 is suitable for engaging with the lock buckle 13 to fix the box cover 2 to the top opening of the box body 1, thereby realizing the cover sealing of the box body 1;

[0027] At the same time, a resistance step 211 is provided on the inner wall of the sealing groove 21 of the box cover 2. When the box cover 2 is closed on the box body 1, the resistance step 211 is adapted to be squeezed and deformed by the external force of the edge seal 11 and engage with the bottom surface of the edge seal 11, thereby realizing secondary fixation and sealing of the box cover 2.

[0028] A vent hole 23 is provided at the center of the box cover 2, and the vent hole 23 is used to ventilate the box body 1;

[0029] like Figure 2 and Figure 4As shown, a buckle edge 31 corresponding to the top step surface 12 of the box body 1 is provided on the outer circumference of the bottom surface of the box body 1, and the outer wall of the buckle edge 31 is suitable for contacting with the inner wall of the edge sealing 11, and a buckle groove 311 adapted to the lock buckle 13 is provided on the buckle edge 31 (wherein the buckle groove 311 and the buckling groove 22 have the same characteristic structure, and for the convenience of description, the two groups of grooves are distinguished and the two grooves are respectively numbered and named), the buckle groove 311 is suitable for matching with the lock buckle 13, so that the lock buckle 13 is snapped into the buckle groove 311, and at this time the buckle edge 31 is in contact with the step surface 12, so that multiple groups of box bodies 1 are suitable for stacking each other and forming a multi-layer structure, so as to achieve the purpose of multi-layer packaging of products;

[0030] The top of the lock buckle 13 has a protruding convex edge (not shown in the figure), and the outer diameter of the convex edge is larger than the outer diameter of the bottom periphery of the lock buckle 13. At the same time, the buckle groove 311 and the buckling groove 22 are provided with grooves adapted to the convex edge. When the lock buckle 13 enters the buckle groove 311 (or the buckling groove 22), the convex edge of the lock buckle 13 is first squeezed and deformed by the inner wall of the buckle groove 311 (or the buckling groove 22). After the convex edge of the lock buckle 13 enters the groove of the buckle groove 311 (or the buckling groove 22), the external force on the convex edge disappears and the convex edge returns to its original state, and then snaps into the groove of the buckle groove 311 (or the buckling groove 22), thereby realizing the snapping between the lock buckle 13 and the buckle groove 311 (or the buckling groove 22);

[0031] At the same time, opening and closing ends 32 are provided at the corners of the buckle edge 31. The opening and closing ends 32 are used to facilitate the separation of the box bodies 1 from each other. The opening and closing ends 32 are suitable for applying a pulling force thereon to separate the two sets of box bodies 1.

[0032] When loading products in layers, first load the products into the corresponding boxes 1. After the products are loaded, stack each group of boxes 1 and apply pressure to the top box 1 to connect the boxes 1 to each other through the cooperation between the buckle groove 311 and the lock buckle 13.

[0033] At this time, the buckle groove 311 conflicts with the step surface 12 and the inner wall of the edge seal 11, and a sealing step 312 is provided at the outer wall edge of the buckle groove 311, and the sealing step 312 is suitable for conflicting with the inner wall edge of the edge seal 11, so as to achieve sealing between the box bodies 1;

[0034] Finally, the box cover 2 is covered in the top of the box body 1, and the box cover 2 is fixed to the top of the box body 1 under the cooperation of the buckle groove 22 and the lock buckle 13. At the same time, the abutment step 211 cooperates with the bottom surface of the edge sealing 11, so as to achieve secondary fixation and sealing of the box cover 2;

[0035] To summarize, the buckle edge 31 is adapted to contact the step surface 12 and the inner wall of the edge seal 11, and the lock buckle 13 cooperates with the buckle groove 311, so that the two groups of box bodies 1 are connected to each other and form a double-layer structure. At the same time, under the mutual contact between the sealing step 312 and the edge of the inner wall of the edge seal 11, the two groups of box bodies 1 are sealed to each other, thereby achieving the purpose of switching between multi-layer and single-layer blister packaging boxes, and solving the problem of inconvenient loading between layers of multi-layer blister packaging boxes.

[0036] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any improvements and modifications within the spirit and principles of the present application and without departing from the principles of the present application shall also be deemed to be within the scope of protection of the present application.
