Abstract

There is disclosed a nursing unit of the type employing a liquid-retention sac disposed in a holder and a nipple, the holder being provided with an annular groove for seating the depending skirt of a snap-on type frictionally secured nipple. To adapt such a nursing unit to receive a nipple which is secured by a screw type retainer a removable threaded adaptor ring is disposed within the annular groove of the holder. The ring cooperates with a threaded nipple retainer to more securely hold the nipple and liquid-retention sac in place, thereby substantially reducing the possibility of accidental or inadvertent removal of the nipple, especially by older infants and, as well, reducing the possibility of leakage of contents from the sac. Existing nursing holders intended to secure a snap-on nipple for use with very young infants can be modified very simply with the instant adaptor ring to now receive a screw down retainer for the nipple.
