the present embodiment is different from embodiment 1 in that the outer bag 10 and the water guide strip 11 are not provided, and the diameter of the inner insertion rod 32 is enlarged and matched with the inner wall of the material taking port 5, and the rest is the same as embodiment 1.

Compared with the example 1, the reminding of the overhigh moisture is only one, and the example 1 is a double reminding, but the implementation cost of the example is relatively low, the example is simple, and the method is suitable for food packaging with relatively fast eating and relatively small volume.

The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
