Abstract
A method for releasing a lid from a base without disturbing contents and without undue lid stress includes flexing two graspable members at separated locations about the lid periphery, thereby providing two distinct initial disengagement locations and overcoming any tendency of the lid to reactively grip the tray when disengagement is initiated. The separated locations are not directly opposite to each other, and can be separations of between 20 and 60 degrees or between 25 and 50 degrees. The lid is then easily removed by lifting the lid upward. The method can include simultaneous and/or sequential flexing of the graspable members by one or both of a user's hands. The graspable members can include lift tabs and/or indentations. In embodiments where the lid further includes press locations, the method includes pressing on the press locations while flexing the graspable members.
