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.

Abstract: This disclosure relates to a tamper-indicating band which is utilized in conjunction with a closure for normally preventing the distortion of the closure as would be required to effect the removal of the closure. A tamper-indicating ring includes a continuous band which must be ruptured in order to remove the tamper-indicating ring. When the processing of the container assembly requires the introduction of heat, the tamper-indicating ring is heated and the band expands and then shrinks. Difficulties encountered with this first expansion and later shrinkage have been solved by forming the band in a plurality of sections connected together by expansion segments.

An internally threaded screw cap is threadable onto external screw threads on the intermediate part which can be held against rotation by means of a downwardly extending skirt portion.

Abstract: A snap-lock device, for securing a dispensing mechanism to the mouth of a container which has an annular bead about the mouth periphery, comprises a bead embracing ring having an axially extending annular recess open at one end of its axial extent to receive the bead. An annular rib, formed with the ring adjacent the open margin of the recess, underlies at least a portion of the bead to prevent axial bead-ring disengagement. A retainer element, engageable on the ring when installed on the bead, exerts a radial force against the ring and holds the rib in underlying relation to the bead. The dispensing mechanism is mounted with one of the ring and element. A rabbeted interlocking arrangement between the ring and element prevents their relative disengagement so that the dispensing mechanism cannot be removed from the container. Therefore, the device can be used with pressurized barrier-type and aerosol containers.
