The unit also includes an annular retaining loop portion which surrounds the base of the valve and is integrally connected to the cap portion by a thin card-like tag portion having a width greater than the width of the cap portion. The tag portion is printed with information identifying the beverage and/or beverage producer and is flexible to permit the cap portion to be attached to the valve while the retaining portion surrounds the base of the valve.
