It can be understood that in other embodiments, the first card strip 32 may also be provided with multiple strips at intervals, and the second card strip 12 may be provided with multiple strips at intervals, with the first card strip 32 and the second card strip 12 being provided in a one-to-one correspondence.
[0046] Further, the first clamping strip 32 and the backing plate 30 are integrally formed, or the first clamping strip 32 and the backing plate 30 are not integrally formed, for example, the first clamping strip 32 is adhered to the backing plate 30, or the first clamping strip 32 is detachably connected to the backing plate 30 by buckling.
[0047] Further, the second clamping strip 12 and the fastening part 11 are integrally formed or not integrally formed.
[0048] Further, the backing plate 30 comprises an operating part 31 outside the sealing piece 22, and a protrusion 33 is connected to the operating part 31, and the backing plate 30 is driven to slide relative to the sealing piece 22 by pulling the protrusion 33.
[0049] Further, the protrusion 33 and the backing plate 31 are integrally formed, or the protrusion 33 and the backing plate 31 are not integrally formed.
[0050] Further, the material of the protrusion 33 and the backing plate 31 can be the same or different.
[0051] When the backing plate 30 is located at the first position or the second position, the protrusion 33 abuts against the sealing piece 22 to limit the position of the backing plate 30.

[0060] Please see Figure 10 and Figure 11 , Figure 10 This illustration shows the structure of the packaging carton, which facilitates sealing and opening, in a sealed state according to another embodiment of this application. Figure 11 It shows Figure 10 The structure of the inner packaging carton in the open state differs from the above embodiment in that, in this embodiment, the protrusion 33 is connected to the lower end of the operating part 31. When the liner 30 is in the first position, the protrusion 33 abuts against the lower edge of the sealing piece 22 corresponding to the rightmost end of the operating part 31, thereby limiting the liner 30 and causing the first clip 32 to engage below the second clip 12. When the liner 30 is in the second position, the protrusion 33 abuts against the lower edge of the sealing piece 22 corresponding to the leftmost end of the operating part 31, thereby limiting the liner 30 and causing the first clip 32 and the second clip 12 to be offset in their length direction.
[0061] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made according to the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
