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.

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, comprising (a) a non-frangible seal strip releasably bonded to said rim about said mouth to extend over the mouth and block discharge of liquid from the container via said mouth, said strip characterized as releasing from said rim in response to internal pressurization of said container by manually squeezing the container and its liquid contents when the container is inverted, causing said contents to increasingly pressure against the strip to sever its bond from the rim, (b) and a holder tab carried by the strip and attached to the neck so as to retain the strip to the neck after it releases from the rim. The method of controllably retaining liquid in and releasing liquid from a squeeze deflectable hollow container having a tubular neck defining a rim, about a neck mouth, and employing a non-frangible seal strip and a holder tab carried by said strip, that includes: (a) bonding the seal strip to said rim said about mouth to extend over the mouth and block discharge of fluid from the container via said mouth, said strip bond characterized as releasing from said rim in response to internal pressurization of said container by manually squeezing the container and its liquid contents when the container is inverted, causing said contents to increasingly press against the strip to sever its bond with the rim, (b) and also bonding said tab to said neck so as to retain the strip to the neck after it releases from the rim.
