A second through hole 7 is arranged on one side of the bag body 1. The other end of the drag sheet 6 passes through the second through hole 7. When the drag sheet 6 is pulled, the sleeve sheet 5 rotates on the inner lining sheet 4; First pattern 8: a plurality of first patterns 8 are arranged at intervals on the cover sheet 5. When the cover sheet is rotated, the first pattern 8 can be exposed from the observation area.

[0043] Preferably, the observation area is the first opening 3, and the bag body 1 is provided with a first detachable portion 2, and after removing the first detachable portion 2, the first opening 3 is formed on the bag body 1. Optionally, the observation area can be a transparent film provided on the bag body 1 instead of the opening, and the inside of the bag body 1 can also be observed.

[0044] Preferably, both side edges of the inner lining sheet 4 are chamfered to facilitate smoother rotation of the sleeve sheet 5 thereon.

[0045] Preferably, the first detachable portion 2 is formed by surrounding an easy tear line.

[0046] Preferably, the inner lining sheet 4 is fixed in the bag body 1 by a connecting piece, and a gap is left between the inner lining sheet 4 and the bag body 1 to facilitate the rotation of the sleeve sheet 5; or the width of the sleeve sheet 5 sleeved on the inner lining sheet 4 is adapted to the width of the bag body 1, and there is a certain friction between the two sides of the sleeve sheet 5 sleeved on the inner lining sheet 4 and the bag body. When the bag body 1 is placed upright, the inner lining sheet 4 placed in the bag body 1 will not fall, and the sleeve sheet 5 can rotate on the inner lining sheet 4 by dragging the sheet 6.

[0047] In this embodiment, the cover sheet 5 can be rotated on the inner lining sheet 4 by dragging the drag sheet 6, so that the pattern thereon moves accordingly, so that the pattern that can be observed from the first opening 3 on the bag body 1 changes. The appearance of the pattern and the shape of the first opening can be set as needed. Embodiment 2:

[0048] This embodiment is based on the embodiment 1 and its structure is modified. The modified technical solution is as follows: The surface of the bag body 1 is provided with a second pattern 9, and the first detachable part 2 is located within the coverage of the second pattern 9.
