Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
208 words
Dispenser for fluent material containers having a portion for providing an aperture in the top of said container, said dispenser comprising a lever, the inner end of which being in the form of a cutter, said lever being pivotally mounted intermediate its end portions to said aperture portion and pivotable between a first position disposed generally parallel to and spanning said container portion and a second position extending upright from the top of said container wherein said cutter end pierces the top of said container to form said aperture, said dispenser further comprising a pliant sleeve within which said lever is longitudinally disposed, said sleeve being affixed at one end thereof about the periphery of said aperture so that the interior of said container communicates with said sleeve, the outer end of said sleeve disposed adjacent the outer end of said lever and being adapted to be open, said sleeve being collapsible to substantially flat condition in said first position for closing said aperture, wherein a portion of said sleeve is disposed between the top of said container and the undersurface of said lever, pivotable movement of said lever to its second position causing the opening of said sleeve into an upstanding tubular pour spout for said container.
Claim 2
Dependent Claim

Dispenser for fluent material containers having a portion for providing an aperture in the top of said container, said dispenser comprising a lever, the inner end of which being in the form of a cutter, said lever being pivotally mounted intermediate its end portions to said aperture portion and pivotable between a first position disposed generally parallel to and spanning said container portion and a second position extending upright from the top of said container wherein said cutter end pierces the top of said container to form said aperture, said dispenser further comprising a pliant sleeve within which said lever is longitudinally disposed, said sleeve being affixed at one end thereof about the periphery of said aperture so that the interior of said container communicates with said sleeve, the outer end of said sleeve disposed adjacent the outer end of said lever and being adapted to be open, said sleeve being collapsible to substantially flat condition in said first position for closing said aperture, wherein a portion of said sleeve is disposed between the top of said container and the undersurface of said lever, pivotable movement of said lever to its second position causing the opening of said sleeve into an upstanding tubular pour spout for said container.
Claim 3
Dependent Claim
226 words
Dispenser for fluent material containers having a portion for providing an aperture in the top of said container comprising a lever in the form of a generally flat strip including a pull tab at the outer end thereof, said lever being pivotably disposed adjacent an edge portion of the aperture, said lever being pivotable between a first position disposed generally parallel to and spanning said container portion and a second position extending upright from the top of said container, said dispenser further including a pliant sleeve affixed along one longitudinal portion thereof to the underside of said lever and affixed at one end thereof about the periphery of said aperture so that the interior of said container communicates with the interior of said sleeve, the outer end of said sleeve disposed adjacent the outer end of said lever and being adapted to be open, said dispenser further including a recess provided in the top of said container, said recess being adapted to receive said strip and to accommodate said sleeve in flat, collapsed condition, beneath said strip for closing said aperture, said dispenser further including means for releasably retaining said lever in an upright position relative to the top of said container, pivotable movement of said lever to its upright position causing the opening of said sleeve into an upstanding tubular pour spout for said container.
