Abstract
Abstract A flexible container having a pouch portion and an opening leading to the pouch. The opening is releasably closable by flexible rib and groove elements formed along the walls of the container. A funnel portion attached to the walls of the container is normally positioned internally of the pouch portion when the container is not being used and is readily extensible outside the pouch when the rib and groove elements are opened and it is desired to remove contents from the container. The funnel portion may come to a point or apex to form a spout which when snipped at the tip thereof allows the contents of the pouch to be controllably released from the container without interfering with the operation of the rib and groove elements.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
In combination: a flexible plastic pouch having opposing front and rear walls with said walls joined at the side edge and bottom edges; interlocking plastic rib and groove elements on the inner surface of the walls of the pouch for releasably closing the opening to the pouch and being spaced downwardly from the top edges to leave flange portions projecting above the elements; a flexible funnel member having side walls joined at their edges and having a base of a width equal to the width of the container walls and sealed continuously to the inner surface of the walls below said rib and groove elements; said funnel member projecting downwardly in the pouch to lie flat between the pouch walls, said funnel member being turned inside out when pulled outwardly of the pouch to dispense the contents, said funnel being tapered from the base toward an apex and being of a length from the base to the apex substantially greater than the length of said flanges so that the apex extends a substantial distance beyond the elements when the funnel is pulled outwardly from the pouch.
Claim 2
Dependent Claim
