ABSTRACT:
A self-storing spout assembly for use on a container having a threaded neck opening comprises, in combination, an annular cap ring having complimentary internal screw threading, a substantially cylindrical neck insert sized and dimensioned for floating retention within the neck opening, a resilient seal, and a hollow spout member. The neck insert has a central orifice and one or more secondary apertures. The hollow spout has one or more radially directed flow openings therethrough, and is dimensioned to releasably, sealingly engage the cap ring and the central orifice. In the pouring configuration fluid flows from the container, through the secondary apertures in the neck insert, into the hollow spout member via the radially directed flow openings, and exits the hollow spout member through an open pouring end thereof. In a storage configuration, the hollow spout member is inserted into the neck insert in an inverted position, such that fluid enters the hollow spout member as aforementioned and is retained therein by a closed base end of the hollow spout member.
