Abstract
A unitary blow-molded hand-held plastic container having improved pouring capability without requiring separate pour spouts is disclosed. The neck has a pair of opposed panels that are pinched inwardly below the finish of the container to afford precise control during pouring.
Claims15
A blow-molded plastic container having an internal integral pour spout to facilitate dispensing of contents from the container, said container having a neck portion terminating in a finish adapted to sealingly engage a removable closure, said neck having a pair of inwardly convex panels that merge together along a common juncture to form a flow channel opening inwardly into said neck and extending to said finish, said neck panels converging in an upward direction toward said finish for defining therebetween a progressively decreasing dihedral angle as they approach said neck finish, whereby said neck panels cooperate to form a progressively tapering pour spout inside the container to facilitate pouring of the contents.
In a blow-molded plastic container having a body portion for containing a flowable material, a finish for dispensing the flowable material, and a neck portion merging the body portion to the finish, the improvement wherein said neck portion comprises a pair of inwardly convex panels forming therebetween an inwardly-open flow channel extending along a common line of juncture of said panels, said flow channel being convex outwardly of said neck and merging into said finish at one interior peripheral location thereof, said neck panels cooperating with said flow channel to define a continuously progressively decreasing dihedral angle in a direction from said container body toward said finish for directing flowable material through said finish, said finish having a circular sealing surface for sealingly engaging a removable closure, said circular sealing surface defining an imaginary elongate tube extending longitudinally therebelow with said neck panels extending into said imaginary tube adjacent said finish, said imaginary tube being completely offset inwardly from the periphery of said container body portion.
A blow-molded plastic container for storing and dispensing a flowable material, the container having a finish and a neck connecting the finish to a container body, the finish defining an opening for dispensing the flowable material and engageable with a removable closure for sealing the opening, the improvement wherein the finish has a circular top flange providing a no-drip pouring edge, said top flange defining an imaginary elongate cylindrical tube extending vertically through the container body;
- the container neck having a pair of panels formed therein on opposite sides thereof, each of said panels extending inwardly into the neck and partially into said imaginary tube;
- said pair of panels converging in both a horizontal and a vertical direction toward the opening so that both transverse and longitudinal cross-sections through the neck define a "V"-shaped configuration which functions as an internal pour spout for directing the flowable material toward said opening.
