ABSTRACT:
Collaspsible spout for dispensing fluent materials from containers such as used for various liquids and/or granular or powdered products. The container includes a top panel provided with an aperture. A lever is pivotally disposed to selectively open and close the aperture and carries on its underside a pliant sleeve sealed at one end about the periphery of the aperture and with its other end adapted to be opened adjacent the outer end of the pivotable lever. In closed position the lever in the form of a flat strip lies generally flush atop the container and for opening the container the lever is pivoted outwardly from the top of the container, thereby automatically extending and unfolding the pliant tubular sleeve. The aperture is reclosable by swinging the strip back against the top of the container. In an alternate embodiment, the lever is disposed within the pliant sleeve and includes a cutting tip at its inner end for cutting the aperture as the lever is pivoted upwardly.
