发明名称 Two-piece handle design for pressure cooker
摘要 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.
