Detailed implementation manners

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts also belong to the scope of protection of the present application.

[0036] As shown in Figure 1 and Figure 2 , a side-opening packaging box disclosed in the present application includes a box body 1. One side in the length direction of the box body 1 is an opening structure. An inner containing box 2 is inserted into the box body 1. One end of the bottom of the inner containing box 2 in the length direction is movably connected to the lower side of the opening end of the box body 1. The inner containing box 2 can freely rotate around its connection point with the box body 1. The cross-sectional shape of the inner containing box 2 is a right trapezoid, and the length of the lower bottom of the inner containing box 2 (reference can be made to the line segment a in Figure 2 ) is equal to the height inside the inner containing box 2 (reference can be made to the line segment b in Figure 2 ), and the height of the inner containing box 2 (reference can be made to the line segment c in Figure 8 ) is equal to the length inside the box body 1 (reference can be made to Figure 2 andFigure 8 The line segment d) therein is equal; the outer surface of the inner accommodating box 2 is coated with a decorative pattern, and observation windows 3 are provided on both side walls in the thickness direction of the box body 1, and through the observation windows 3, the decorative pattern on one outer side wall of the inner accommodating box 2 can be seen.

[0037] In the above embodiments, the packaging box of the present application is composed of the outer box body 1 and the inner accommodating box 2 therein. One side of the bottom of the inner accommodating box 2 is movably connected to the bottom at the opening of the side of the box body 1. During production, multiple individually packaged powders or pills can be placed in the inner accommodating box 2. When a user needs to take medicine, the inner accommodating box 2 only needs to be rotated from the opening of the box body 1, so that the inner accommodating box 2 can be rotated out of the box body 1, and the medicine in the inner accommodating box 2 can be exposed in the user's field of vision for the user to take. After taking the medicine, only the inner accommodating box 2 needs to be pushed to rotate it back into the box body 1. Compared with the prior art, not only is the operation method novel, but also the operation process is simple and convenient, and it has good practicability during use.

[0038] In addition, the decorative pattern coated on the outer surface of the inner accommodating box 2 can be seen by the user through the observation windows 3 on the side wall of the box body 1. During actual production, a pattern corresponding to the style of the pattern on the surface of the inner accommodating box 2 can be coated on the outside of the box body 1 as needed. In this way, during the process of pulling out the inner accommodating box 2, the pattern presented in the observation windows 3 will change and cooperate with the pattern on the surface of the box body 1, effectively increasing the artistic quality of the appearance of the packaging box and making it more beautiful on the basis of practicality. The specific decorative patterns on the surfaces of the inner accommodating box 2 and the box body 1 can be selected by the manufacturer according to its own situation, and the present application does not make any limitations.

[0039] Furthermore, as Figure 1 and Figure 2 shown, an arc-shaped notch 4 is provided on the upper side of the open end of the box body 1.

[0040] In the above embodiments, the arc-shaped notch 4 provided at the top of the side opening of the box body 1 facilitates the user to quickly open the inner accommodating box 2 from the box body 1.

[0041] Furthermore, as Figures 3 - 10 shown, the box body 1 includes a first cardboard 11, a second cardboard 12, a third cardboard 13, and a fourth cardboard 14 that are connected in sequence. One side of the first cardboard 11 away from the second cardboard 12 and one side of the fourth cardboard 14 away from the third cardboard 13 are connected together;

[0042] The arc-shaped notch 4 is provided on one side in the length direction of the second cardboard 12; the two observation windows 3 are respectively provided on the first cardboard 11 and the third cardboard 13;

[0043] A limiting cardboard 15 is connected to each of the second cardboard 12 and the fourth cardboard 14 on the side away from the arc-shaped notch 4, and a sealing cardboard 16 is connected to each of the first cardboard 11 and the third cardboard 13 on the side corresponding to the limiting cardboard 15;

[0044] The two limiting cardboards 15 are bent towards the closer side of the second cardboard 12 and the fourth cardboard 14 in the box body 1, and the two sealing cardboards 16 are horizontally overlapped on the two limiting cardboards 15, and the two sealing cardboards 16 are bonded together.

[0045] In the above embodiments, the main part of the box body 1 of the present application is surrounded by the first cardboard 11, the second cardboard 12, the third cardboard 13 and the fourth cardboard 14. When they are surrounded together, the side of the first cardboard 11 away from the second cardboard 12 is exactly close to the side of the fourth cardboard 14 away from the third cardboard 13. At this time, connecting them together forms a closed frame structure. Since the side of the box body 1 provided with the arc-shaped notch 4 is an opening, the other opposite end of the frame structure surrounded by the first cardboard 11, the second cardboard 12, the third cardboard 13 and the fourth cardboard 14 needs to be closed. The sealing cardboards 16 provided on the first cardboard 11 and the third cardboard 13 are bent, folded and adhered together in sequence, and then the end opening of the box body 1 opposite to the opening can be just closed. After the limiting cardboards 15 on the second cardboard 12 and the fourth cardboard 14 are bent by 90°, they can form a certain supporting and limiting effect on the two sealing cardboards 16, preventing the sealing cardboards 16 from cracking towards the inside of the box body 1 when subjected to external forces during use or assembly.

[0046] Further, as Figure 8 and Figure 9 shown, a first tongue 5 is provided on the side of the first cardboard 11 away from the second cardboard 12. The first tongue 5 is bent from the first cardboard 11 to the inside of the fourth cardboard 14 and bonded to the fourth cardboard 14.

[0047] In the above embodiments, when the first tongue 5 provided on the first cardboard 11 approaches the fourth cardboard 14 at the end of the first cardboard 11 away from the second cardboard 12, the first tongue 5 extends into the inside of the fourth cardboard 14 through bending, so as to overlap with the fourth cardboard 14. By applying glue to the overlapping area of the first tongue 5 and the fourth cardboard 14, they can be bonded together, so that the first cardboard 11, the second cardboard 12, the third cardboard 13 and the fourth cardboard 14 connected in sequence are firm and solid.

[0048] Further, as Figures 3 - 10As shown, the accommodating inner box 2 includes a fifth cardboard 21, a sixth cardboard 22, a seventh cardboard 23, and an eighth cardboard 24 connected in sequence. Both the sixth cardboard 22 and the eighth cardboard 24 are right trapezoids. One side of the fifth cardboard 21 away from the sixth cardboard 22 is connected to one side of the eighth cardboard 24 away from the sixth cardboard 22. A ninth cardboard 25 is connected to the side of the eighth cardboard 24 opposite to its inclined side. One end of the ninth cardboard 25 away from the eighth cardboard 24 is connected to the sixth cardboard 22.

[0049] In the above embodiments, when the fifth cardboard 21, the sixth cardboard 22, the seventh cardboard 23, and the eighth cardboard 24 are surrounded together, they can form the basic framework of the accommodating inner box 2. Among them, the sixth cardboard 22 and the eighth cardboard 24 are right trapezoids. The height of the fifth cardboard 21 is equal to the length of the upper base of the right trapezoid (the size of the height of the fifth cardboard 21 is preferably such that the accommodating inner box 2 has sufficient rotation range in the box body 1, and the specific value is not limited. The user can make an adaptive selection according to the situation of their own products). The height of the seventh cardboard 23 is equal to the length of the lower base of the right trapezoid. In this way, the cross-section of the framework formed by them is a right trapezoid. When the accommodating inner box 2 of this structure rotates in the box body 1 around the end of its lower base away from the inclined side, the rotation range of the accommodating inner box 2 in the box body 1 can be increased, so that more parts of the accommodating inner box 2 can be exposed to the outside of the box body 1, facilitating the user to observe the medicines in the accommodating inner box 2. When the ninth cardboard 25 connected to the eighth cardboard 24 is bent to be perpendicular to the eighth cardboard 24, the ninth cardboard 25 can form the bottom plate of the accommodating inner box 2 between the eighth cardboard 24 and the sixth cardboard 22. Thus, the accommodating inner box 2 can hold items.

[0050] Furthermore, as Figures 3 - 6 shown, a second tongue 6 is connected to the side of the fifth cardboard 21 away from the sixth cardboard 22. The second tongue 6 is bent from the fifth cardboard 21 towards the inside of the eighth cardboard 24 and is bonded to the eighth cardboard 24. A third tongue 7 is connected to the side of the ninth cardboard 25 away from the eighth cardboard 24. The third tongue 7 is bent from the ninth cardboard 25 towards the inside of the sixth cardboard 22 and is bonded to the sixth cardboard 22.

[0051] In the above embodiments, when the second tongue 6 on the fifth cardboard 21 approaches the eighth cardboard 24 at the end of the fifth cardboard 21 away from the sixth cardboard 22, it can be bent towards the inside of the eighth cardboard 24, so as to overlap with the eighth cardboard 24 and be bonded and fixed. Similarly, after the third tongue 7 on the ninth cardboard 25 is bent towards the inside of the sixth cardboard 22, it will overlap with the sixth cardboard 22 and be bonded and fixed. In this way, it can ensure that the structure of the assembled accommodating inner box 2 is stable and firm enough.

[0052] Furthermore, as Figures 3 - 7As shown, a lining board 8 is connected to the hypotenuse of the sixth cardboard 22 and the eighth cardboard 24, and on the same side of the seventh cardboard 23, and the lining board 8 is respectively folded to the inner sides of the sixth cardboard 22, the eighth cardboard 24 and the seventh cardboard 23.

[0053] In the above embodiments, when the lining boards 8 provided on the sixth cardboard 22, the seventh cardboard 23 and the eighth cardboard 24 are folded to their respective inner sides, the overall strength of the accommodating inner box 2 can be improved to protect the safety of the contents. If there is a concern about the lining board 8 warping after folding, glue or double-sided tape can also be used to fix the folded lining board 8.

[0054] Furthermore, as Figures 3 - 7 shown, a guiding cardboard 9 is connected to the side of the fifth cardboard 21 close to the lining board 8. After the guiding cardboard 9 is folded into the accommodating inner box 2, it is in an inclined state, and its end far from the fifth cardboard 21 abuts against the ninth cardboard 25.

[0055] In the above embodiments, since the accommodating inner box 2 will not separate from the box body 1 during the rotation process, even when it rotates to the maximum angle, part of it will still be inside the box body 1. If the guiding cardboard 9 connected to the fifth cardboard 21 is placed in the accommodating inner box 2 as described above, when the accommodating inner box 2 is opened, the medicines in the part of the accommodating inner box 2 inside the box body 1 can also slide along the guiding cardboard 9 to the opening of the box body 1 for the user to take, which increases the convenience of the present application.

[0056] Furthermore, as Figures 3 - 10 shown, the box body 1 and the accommodating inner box 2 are integrally formed, and the side of the seventh cardboard 23 opposite to the side where the lining board 8 is connected to it is connected to the side of the fourth cardboard 14 far from the limiting cardboard 15.

[0057] In the above embodiments, the cardboard of the box body 1 and the cardboard of the accommodating inner box 2 of the present application are a complete cardboard. Creases will be set in advance at the joints of each cardboard during production. During assembly, the production workers only need to assemble according to the creases in sequence, which is convenient for production, transportation and assembly.

[0058] The implementation principle of this embodiment is as follows: Before use, first enclose the fifth cardboard 21, the sixth cardboard 22, the seventh cardboard 23 and the eighth cardboard 24. Bend the ninth cardboard 25 upward until the third tongue 7 extends into the inner side of the sixth cardboard 22, and then bond and fix the third tongue 7 and the sixth cardboard 22. Then bond the second tongue 6 on the fifth cardboard 21 to the inner side of the eighth cardboard 24. After that, fold the lining boards 8 on the sixth cardboard 22, the seventh cardboard 23 and the eighth cardboard 24, and the guiding cardboard 9 on the fifth cardboard 21 inward in sequence to complete the assembly work of the accommodating inner box 2.

[0059] Next, the worker holds the assembled inner accommodating box 2 by hand and starts to turn it over along the third cardboard 13, the second cardboard 12, and the first cardboard 11 connected thereto in sequence, so as to enclose the first cardboard 11, the second cardboard 12, the third cardboard 13, and the fourth cardboard 14 into a rectangle, and bond the first tongue 5 on the first cardboard 11 and the fourth cardboard 14 together. This rectangle is the basic framework of the box body 1. Subsequently, the two limiting cardboard 15s are folded inward into the box body 1, and then the two sealing cardboard 16s are sequentially overlapped on the two limiting cardboard 15s, and the mutually adjacent sides of the two sealing cardboard 16s are bonded together, thus completing the assembly work of the packaging box of the present application. The specific assembly process can be referred to Figures 3 - 10 .

[0060] The inner accommodating box 2 inside the assembled packaging box can be used to place medicines such as powders or pills with independent packages. After the medicines are placed, the outside of the packaging box is heat-sealed. When a user uses it for the first time subsequently, the user opens the heat-sealing film, puts a finger into the arc-shaped notch 4 to buckle out the inner accommodating box 2, and then the medicines can be taken. After taking, pushing the inner accommodating box 2 to reset it inside the box body 1 can complete the taking operation. When taking repeatedly subsequently, other operation methods are the same as above except that the heat-sealing film does not need to be opened again. Compared with the prior art, the present application is significantly more convenient to use, and the paper material is used, which is convenient for recycling and also convenient for printing patterns on the packaging box to make it more beautiful. In addition, the observation window 3 design of the box body 1 of the present application can make the whole packaging box more artistic.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
