Abstract

Abstract A salt dispenser includes a container with the top having a pouring aperture and a plurality of sifting apertures disposed thereabout. A spout is pivotably secured to the top of the container so that when the sifting apertures are open the pouring aperture is sealed off, and when the pouring aperture is open the sifting apertures are sealed off. More particularly, the spout contains a front piece located outside the container and an integral flange extending therein. When the flange is aligned with the sifting apertures, thus sealing them off, the front piece is in an upright position relative to the pouring aperture, thereby permitting salt to pour out. When the front piece is pivoted to a closed position, thereby sealing the pouring aperture, the flange inside the container is brought out of alignment with the sifting apertures, thus opening them up. The dispenser and spout herein disclosed can selectively permit pouring or sifting of granular material by providing a unique spout cooperating with sifting and pouring apertures, whereby a single manipulation of the spout is needed to alternate between the pouring and sifting functions. There is disclosed dispenser means comprising a single opening having bulk pour and drag sift apertures with the unique spout configuration segregating the pour aperture section from the array of sifter apertures, and controlling the alternate functions by flipping the spout from one position to another.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 137 words
A dispenser for pouring or sifting granular material having an apertured wall and including a trapezoidal pouring aperture and a plurality of sifting apertures; a spout having a first closure panel of generally trapezoidal shape adapted when in a first position of pivotal adjustment to overlie and seal off said pouring aperture; a pair of spout sidewalls extending from opposite sides of said closure panel and inwardly of said pouring aperture; and second closure means carried by at least one of said sidewalls within said dispenser adapted to seal off said sifting apertures when said first closure panel is in a second position of pivotal adjustment, said pouring aperture discharging through said spout when said closure panel is in said second position and said sifting apertures are unsealed when said closure panel is in said first position.
Claim 2
Dependent Claim 137 words
A dispenser for pouring or sifting granular material having an apertured wall and including a trapezoidal pouring aperture and a plurality of sifting apertures; a spout having a first closure panel of generally trapezoidal shape adapted when in a first position of pivotal adjustment to overlie and seal off said pouring aperture; a pair of spout sidewalls extending from opposite sides of said closure panel and inwardly of said pouring aperture; and second closure means carried by at least one of said sidewalls within said dispenser adapted to seal off said sifting apertures when said first closure panel is in a second position of pivotal adjustment, said pouring aperture discharging through said spout when said closure panel is in said second position and said sifting apertures are unsealed when said closure panel is in said first position.
Claim 3
Dependent Claim 47 words
The dispenser of claim 1 including a single array of sifting apertures adjacent an edge of said pouring aperture and wherein said second closure means comprises a single flange adapted to overlie and seal said array when said first closure panel is in said second discharge position.
Claim 4
Dependent Claim 55 words
The dispenser of claim 1 wherein the apertured wall is the top end wall of a container and the sifting apertures comprise at least one array of apertures defining an edge of the pouring aperture, at least one spout sidewall being interposed between the said pouring aperture and the said one array of sifting apertures.
Claim 5
Dependent Claim 49 words
The dispenser of claim 1 wherein the apertured wall is an end wall of a container and the sifting apertures comprise at least one array of apertures forming an edge of the pouring aperture with one spout sidewall separating the said pouring aperture and said array from each other.
Claim 6
Dependent Claim 23 words
The dispenser of claim 4 wherein said array of sifting apertures comprises a series of notches in the border of the pouring aperture.
Claim 7
Dependent Claim 53 words
The dispenser of claim 1 including a pair of spaced arrays of sifting apertures, said second closure means comprising a pair of flanges coextensive with the said spaced arrays which are unsealed when said spout is in said first closure position and are sealed when said spout is in said second discharge position.
Claim 8
Dependent Claim 46 words
The dispenser of claim 1 including arrays of sifting apertures adjacent opposite edges of said pouring aperture and wherein said second closure means comprises a pair of closure flanges, each adapted to underlie and seal an array when said spout is in said second discharge position.
Claim 9
Dependent Claim 18 words
The dispenser of claim 7 wherein the arrays and the closure flanges are of corresponding area and configuration.
Claim 10
Dependent Claim 27 words
The dispenser of claim 1 wherein the said spout includes a generally triangular shaped flange substantially coextensive in area with a generally triangular array of sifting apertures.
