How can I shoot still life with almost no depth of field?

What you want is not "almost no depth of field", but "greater depth of field". The scene in the depth of field is clear and sharp.

The depth of field is directly proportional to the aperture value of the lens, directly proportional to the square of the shooting distance and inversely proportional to the square of the focal length of the lens.

If you want a large depth of field, you must narrow the aperture under the premise of proper exposure, try to use a short focal length under the premise of perspective, and try to shoot under the premise of magnification.

If all the effects are not ideal, then use Sam's law to get extraordinary depth of field by shifting axis and swinging, but only large-format technology cameras have such a function.

You probably use DC, the focal length of the actual lens is very short, and the phenomenon of insufficient depth of field is really rare. You can try to make the perfume more compact, shoot it farther with a shorter focal length (that is, leave more richness outside the main body when composing), close the smallest aperture (fill the light if the light is insufficient), and then cut off the excess richness and leave the main body.
