A cookware handle includes a plastic grip portion molded over a portion of an insert. The insert inserts into a bore of a flange. The grip portion is externally flush with the flange interface and the insert internally connects the grip portion to the flange. This allows the grip portion to be over molded on a first part of the insert so the other portion can be welded or otherwise attached to the flange after external surface finishing of the flange. The insert and flange may be welded together along a portion of the insert that contacts the flange within the bore and that is not visible when the flange is attached to a cookware vessel sidewall to provide the grip molded as a handle for the cookware vessel.

1. A handle assembly for a cookware article comprising: (a) a metal flange having an inner face and an outer face, the inner face adapted for contacting a curved outer wall of a cookware article, wherein a bore extends from the outer face toward the inner face and defines at least a first cavity therebetween;(b) an insert having a proximal end and a distal end, wherein the proximal end is received within the first cavity of the bore and secured therein when the proximal end is affixed to the flange within the bore; and(c) a grip member having a proximal end and a distal end and comprising a polymeric material over molded at least a portion of the distal end of the insert, the grip member having an external surface contour at a proximal end that is flush with an adjacent portion of the flange when the proximal end of the insert is secured in the first cavity. 2. The handle assembly for a cookware article according to claim 1, wherein the proximal end of the insert has a metal tab portion having a cross-section dimension complementary to a cross-section dimension of the bore, wherein the metal tab portion engages the bore along the corresponding complementary cross-section dimension of the bore when received therein, and wherein the proximal end is affixed to the flange along the engaged interface of the metal tab portion and the bore by a weld. 3. The handle assembly for a cookware article according to claim 2, wherein the bore defines a channel extending proximally from the first cavity toward the inner face of the flange, the channel having at least one cross-section dimension smaller than a cross-section dimension of the first cavity, and wherein the complementary cross-section dimension of the bore is located along the channel. 4. The handle assembly for a cookware article according to claim 1, wherein the bore extends from the outer face to the inner face of the flange, and wherein the first cavity is adjacent to the outer face and the bore defines a second cavity adjacent to the inner face. 5. The handle assembly for a cookware article according to claim 4, wherein the proximal end of the insert comprises a metal tab portion that extends at least partially into the second cavity, and wherein the metal tab portion is affixed to a portion of the bore defining the second cavity by a weld. 6. The handle assembly for a cookware article according to claim 1, wherein the bore defines a channel extending between the first cavity and a second cavity, the channel having at least one cross-section dimension smaller than a cross-section dimension of the first cavity, and wherein a length of the proximal end of the insert is adapted to fill at least a portion of a length of the channel when the proximal end of the insert is secured within the first cavity. 7. The handle assembly for a cookware article according to claim 1, wherein the bore defines a channel extending proximally from the first cavity toward the inner face of the flange, the channel having at least one cross-section dimension smaller than a cross-section dimension of the first cavity, and wherein a length of the proximal end of the insert and a length of the channel comprise complementary cross-sections such that the length of the proximal end of the insert fills the length of the channel when the proximal end of the insert is secured with the first cavity. 8. The handle assembly for a cookware article according to claim 1, wherein, when the proximal end of the insert is secured in the first cavity, a length of the proximal end within the first cavity is spaced apart from the surrounding portions of the flange defining the first cavity. 9. The handle assembly for a cookware article according to claim 1, wherein the bore defines a channel extending proximally from the first cavity toward the inner face of the flange, the channel having at least one cross-section dimension smaller than a cross-section dimension of the first cavity, and wherein the proximal end of the insert comprises: (a) a metal tab portion having at least one cross-section dimension complementary to a cross-section dimension of the channel;(b) a flared wedge portion, distal of the metal tab portion, having a distally decreasing cross-section adapted to complement a distally decreasing cross-section of the first cavity along a corresponding length of the bore when the proximal end of the insert is secured in the first cavity; and(c) a distal portion, distal of the flared wedge portion, wherein the distal portion has a cross-section dimension less than the corresponding cross-section dimension of flared wedge portion along the distally decreasing cross-section, and wherein the distal portion is space apart from surrounding portions of the bore defining the first cavity when the proximal end is secured therein. 10. The handle assembly for a cookware article according to claim 1, wherein a proximal length of the distal end of the insert defines a cavity adapted to receive a distal length of the proximal end of the insert. 11. The handle assembly for a cookware article according to claim 10, wherein the outer face of the flange includes mating structures adapted to mate with mating structures disposed along the proximal length of the distal end of the insert, wherein the proximal end of the insert is compressed between the flange and the distal end of the insert when the proximal end of the insert is secured in the first cavity. 12. The handle assembly for a cookware article according to claim 11, wherein the mating structures disposed along the proximal length of the distal end of the insert are proximal of the grip member. 13. The handle assembly for a cookware article according to claim 11, wherein the mating structures comprise threads adapted for screwing the distal end of the insert to the distal face of the flange. 14. The handle assembly for a cookware article according to claim 10, wherein the distal end of the insert further defines a cavity along a distal portion thereof, and wherein the handle assembly further comprises a cap closure having mating structures adapted to mate with mating structures disposed along the distal portion of the distal end of the insert to enclose the cavity.
