Abstract:
1. An anti-refill package that includes: a container including: a check element separate from the container and carried in the container neck between the valve seat and the valve retainer, wherein when the product is in an inverted position the check element seats against the retaining surfaces such that at least one flow path is defined between the check element and the valve retainer, and when the product is in an upright position the check element seals against the check element sealing surface so as to prevent refilling of the container; and a closure including a base wall and an outer annular skirt extending axially from the base wall, and being removably secured to the neck finish and removably secured to the check element via a releasable direct coupling between the check element and the closure base wall in a location radially within the outer annular skirt, wherein removal of the closure from the neck separates the check element from the closure so that the check element functions both as a valve element of the anti-refill valve and as an indication that the package has been opened, wherein the check element is a pendant that drops into the container upon closure removal.
