A textile tube on which yarn is wound to form a pack comprises a body having a tubular body extending between opposed ends and an outer surface. The deformation member is deformed due to external light that is incident on the flexible display device, and thus the flexible display device is deformed, thereby allowing the external light to be blocked. A plurality of angled flutes are provided on the body, tapering downwardly for preventing solids from reentering the pump barrel after pump operations are ceased and thereby damaging pump components once pump operations are resumed. At least two non-return valves are included. The gaming device selects the presentation based on the probabilities of being selected associated with the presentations.
