An improved pressure cooker design including a two-piece handle utilizing a common connection point to a cover to increase resistance to damage due to over tightening of connecting screws while simultaneously allowing the use of a conventional handle size with a reduction in overall packaging size.
An improved pressure cooker design including a two-piece handle utilizing a common connection point to a cover to increase resistance to damage due to over tightening of connecting screws while simultaneously allowing the use of a conventional handle size with a reduction in overall packaging size. The two-piece handle design includes a cover base portion and a cover grip portion wherein a pair of nuts are mounted within the cover base portion to receive coupling screws at both ends of the nuts for joining the cover and the cover grip portion to the cover base portion. Tightening of the coupling screws provides for continuous metal on metal contact eliminating damage to weaker polymeric materials while allowing a consumer to quickly and easily attach the cover grip portion of the two-piece handle to the cover base portion at a point of use so as reduce overall packaging dimensions.

A method for reducing packaging dimensions for a pressure cooker having a full-sized handle assembly, comprising: providing a pressure cooker having a cooking pot, a cover assembly and a handle assembly, the handle assembly including a base portion and a grip portion, wherein the cover assembly i
1. A method for reducing packaging dimensions for a pressure cooker having a full-sized handle assembly, comprising: providing a pressure cooker having a cooking pot, a cover assembly and a handle assembly, the handle assembly including a base portion and a grip portion, wherein the cover assembly includes at least one cover fastener, the base portion includes at least one hex nut mounted within at least one base aperture and the grip portion includes at least one grip fastener;attaching the base portion to the cover assembly by inserting the at least one cover fastener through the cover assembly and into the corresponding hex nut of the base portion;packaging the pressure cooker with the grip portion being unattached to the base portion; andconnecting the grip portion to the base portion at a point of use by inserting the at least one grip fastener through the grip portion and into the corresponding hex nut of the base portion. 2. The method of claim 1, wherein the step of attaching the base portion to the cover assembly, further comprises: directing each cover fastener through a cover aperture in the cover assembly, each cover aperture being aligned with the corresponding hex nut in the base portion. 3. The method of claim 2, wherein the step of connecting the grip portion to the base portion assembly, further comprises: directing each grip fastener through a grip aperture in the grip portion, the grip aperture being aligned with the corresponding hex nut in the base portion. 4. The method of claim 3, wherein the step of directing each grip fastener through a grip aperture, further comprises: positioning a shaped projection on the grip portion within a shaped recess on the base portion to align the grip apertures with the hex nuts. 5. The method of claim 1, wherein the step of attaching the base portion to the cover assembly, further comprises: capturing an interlock structure between the base portion and the cover assembly. 6. The method of claim 1, wherein the step of attaching the base portion to the cover assembly, further comprises: inserting an interlock structure on the cover assembly into a slide bore defined by the base portion, wherein misalignment of the interlock structure with the slide bore prevents formation of a seal between the cover assembly and the pot for pressurization of the pressure cooker. 7. The method of claim 1, wherein the step of attaching the base portion to the cover assembly, further comprises: aligning a pair of alignment apertures on the cover assembly with a pair of base apertures for insertion of the cover fastener into the front end of each hex nut. 8. The method of claim 1, wherein the step of attaching the base portion to the cover assembly further comprises: inserting a shaped projection of the grip portion into a corresponding shaped recess defined in the base portion, wherein insertion of the shaped projection into the shaped recess aligns the base portion and grip portion for joining with at least one grip fastener. 9. A method for reducing packaging dimensions for a consumer appliance, comprising: providing a cover assembly including a handle assembly having a base portion and a grip portion, the base portion including a hex nut mounted within each of a plurality of base apertures, the cover assembly further including a plurality of cover fasteners and the grip portion including a plurality of grip fasteners;attaching the base portion of the handle assembly to the cover assembly by inserting each cover fastener through the cover assembly and into the corresponding hex nut of the base portion;packaging the cover assembly and handle assembly with the grip portion of the handle assembly being unattached to the cover assembly; andconnecting the grip portion to the base portion by inserting each grip fastener through the grip portion and into the corresponding hex nut of the base portion such that the handle assembly and the cover assembly define a consumer appliance. 10. The method of claim 9, wherein the step of attaching the base portion to the cover assembly, further comprises: directing each cover fastener through a cover aperture in the cover assembly, the cover aperture being aligned with the corresponding hex nut in the base portion. 11. The method of claim 10, wherein the step of attaching the grip portion to the base portion assembly further comprises: directing each grip fastener through a grip aperture in the grip portion, the grip aperture being aligned with the corresponding hex nut in the base portion. 12. The method of claim 11, wherein the step of directing each grip fastener through the grip aperture, further comprises: positioning a shaped projection on the grip portion within a shaped recess on the base portion to align the grip aperture with the corresponding hex nut in the base portion. 13. The method of claim 9, wherein the step of attaching the base portion to the cover assembly, further comprises: capturing an interlock structure between the base portion and the cover assembly. 14. The method of claim 9, wherein the step of attaching the base portion to the cover assembly, further comprises: inserting an interlock structure on the cover assembly into a slide bore defined by the base portion, wherein insertion of the interlock structure into the slide bore aligns the base portion with cover assembly. 15. The method of claim 9, wherein the step of connecting the grip portion to the cover assembly, further comprises: inserting a shaped projection of the grip portion into a corresponding shaped recess defined in the base portion, wherein insertion of the shaped projection into the shaped recess aligns the base portion and grip portion for joining with the grip fasteners. 16. The method of claim 9, wherein the consumer appliance is a pressure cooker.
