The apparatus further comprises an annular display disc which is configured to fit through opening into chamber. The housing and annular display disc are provided with corresponding profiles which interengage through relative axial rotation to releasably secure the annular display disc to the raised floor of the housing. The annular display disc has a pair of diametrically opposed tabs on the radially inner periphery thereof. Each tab has a drive surface-which is accessible through opening-for transmitting applied torque to the annular display disc to engage/disengage the profiles.</p>
