Abstract
A chest suitable for use in picnicking formed by an upwardly opening container and lid structure for closing same. The lid has a central portion interposed between end portions. The lid end portions are hinged to the lid central portion to permit partially opening of the chest at its opposite ends. The lid central portion is further detachably hinged to the side walls of the container at diametrically opposed points to permit full opening of the chest or complete removal of the lid therefrom. The chest disclosed is formed by enclosing selectively dimensioned pieces of rigid heat insulating material in flexible waterproof covering material along with additional insulation material. Snap fastener mechanism associated with flaps joined with the lid central portion may be employed for detachably connecting the lid on the container structure.
