Abstract: A container for disposing of waste includes a receptacle, a first pivoting member having a first disposal surface and a first pair of opposing sides, and a second pivoting member having a second disposal surface and a second pair of opposing sides. The second pair of opposing sides are operatively coupled to the first pair of opposing sides such that waste deposited on either the first disposal surface or the second disposal surface causes concurrent counter rotation of both the first pivoting member and the second pivoting member. The first pivoting member includes a pair of opposing projections secured in a stationary position to the first pair of opposing sides and the second pivoting member includes a pair of opposing apertures formed in a stationary position in the second pair of opposing sides. The opposing projections translate within the opposing apertures during the concurrent counter rotation.

Abstract: A container for disposing of waste includes a receptacle and a first pivoting member functionally associated with the receptacle. The first pivoting member includes a first disposal surface. A second pivoting member functionally associated with the receptacle includes a second disposal surface. The second pivoting member is operatively coupled to the first pivoting member such that waste deposited on either the first disposal surface or the second disposal surface causes concurrent counter rotation of both the first pivoting member and the second pivoting member to dispose of the waste into the receptacle.

Abstract: A valve and method are provided wherein the valve has a membrane which is molded and cured in a naturally cupped or concave shape, but wherein the membrane is elastically inverted or deflected inside-out so that the direction of concavity is reversed. The membrane is positioned concentrically within a cylindrical or tubular dispensing spout so that the inverted membrane is cupped toward an exit direction of the spout. By inverting the membrane, a reliable radially-outward sealing bias is formed between a peripheral edge of the membrane against an interior of the tubular spout. When mounted on the bottom of a squeeze container, the valve is effective to dispense fluid from the container when squeezed, permit air to breathe back into the container after squeezing, and to sealably prevent leakage from the container.

Abstract: In a closure for a squeeze container, a first valve component is provided which includes an integrally formed membrane and central stem, and a second valve component is provided which includes a tubular dispensing spout. The first and second components are snap-assemblable so that the stem and membrane are fixed concentrically within the tubular dispensing spout so that a periphery of the inverted membrane annularly contacts a wall of the spout. This causes a radially-directed sealing bias is formed between the inverted membrane and the spout.
