No. Bulbs need to be left alone for the leaves to turn brown naturally - a minimum of six weeks after flowering in the case of daffodils. If you don't, then the bulb has no time to store energy or manufacture flowers for next year.
If you need the containers, plant the bulbs in a spare bit of soil to allow them to die back fully. Once the leaves have died you can take them up and store them in a cool, dry spot until re-planting in September, although not all bulbs like being out of the soil - snowdrops, for example, will simply dry out and die.
If you can't put them in soil to allow them to die back naturally you may as well bin them.
