An upright hollow cylindrical body is provided including a hollow laterally outwardly projecting prong on one side. The prong tapers outwardly from the body and is pointed at its outer end. Further, the prong is generally in the shape of a three-sided pyramid somewhat elongated in a direction extending longitudinally of the hollow body. Two sides of the prong extend longitudinally of the body and a short side of the prong extends transversely of the body. The interior of the prong opens directly into the interior of the body and the two long sides of the prong are provided with openings therethrough whereby, when the prong is pushed through the side wall of a container for granular material, granular material may flow through the openings, into the interior of the prong and then directly into the interior of the hollow body. The lower end of the hollow body includes a manually actuatable dispensing door whereby granular material within the body may be dispensed therefrom.
A pouring spout including a multi-sided hollow body, a hollow outwardly tapering prong carried by and projecting outwardly from one side of said body, said one side of said body having an opening formed therein communicating the interiors of said prong and body for rapid flow of granular material from within the interior of said prong into the interior of said body, said body defining a discharge opening remote from said prong, closure means shiftably supported from said body and rapidly movable into and out of positions closing and opening the discharge opening, said prong including side walls extending outwardly from said body and converging toward a pointed outer end of said prong, spring means operably connected between said body and closure means yieldingly biasing the latter toward its closed position, and operator means shiftably supported from said body and operatively connected with said closure means for movement of said closure means between its open and closed positions upon shifting of said operator means relative to said body, said prong being in the form of a multisided pyramid, two adjacent sides of said prong being defined by the sets of corresponding legs of a plurality of side-by-side V-shaped teeth spaced along said prong and progressively increasing in size outwardly from said body.
A pouring spout including an upstanding elongated hollow body, a hollow outwardly tapering prong carried by and projecting outwardly from one side of said body, said one side of said body having an opening formed therein communicating the interiors of said prong and body for rapid flow of granular material from within the interior of said prong into the interior of said body, the lower end of said body defining a downwardly opening discharge opening, closure means shiftably supported from said body and rapidly movable into and out of positions closing and opening the discharge opening, said prong including side walls extending outwardly from said body and converging toward a pointed outer end of said prong, at least one of said prong side walls having at least one opening formed therethrough, spring means operably connected between said body and closure means yieldingly biasing the latter toward its closed position, and operator means shiftably supported from said body for back and forth oscillating movement relative thereto between active and inactive positions and readily engageable from the exterior of said body, connecting means operatively connected between said closure means and said operator means for movement of said closure means between its open and closed positions upon shifting of said operator means between its active and inactive positions, respectively, said connecting means including an elongated longitudinally reciprocal rod extending lengthwise in said body, connected at its lower end to said closure means, and connected at its upper end to said operator means, wherein said prong is generally in the form of a three-sided pyramid, at least two sides thereof having at least one opening formed therethrough, wherein said two sides of said pyramidal prong are defined by the sets of corresponding legs of a plurality of inverted V-shaped teeth spaced along said prong and progressively increasing in size outwardly from said body, the third side of said prong closing the space between the legs of the outermost inverted V-shaped tooth.
