ABSTRACT:
A device for controllably retaining liquid in and releasing liquid from a squeeze deflectable hollow container having a tubular neck defining a rim, about a mouth defined by the neck, incorporates a seal strip bonded to the rim about the mouth to extend over the mouth and block discharge of liquid from the container via the mouth. The strip is characterized as releasing from the rim in response to manual squeezing of the bottle and its liquid contents when the bottle is inverted, causing the contents to increasingly press against the strip; and a holder tab is carried by the strip and attached to the neck so as to retain the strip to the neck after it releases from the rim.
