Abstract
A collapsible camp stove assembly which is characterized by a lap and groove joint between the bottom and the sides and between the top and the sides such that these basic members do not need secondary members to form suitable joints and such as to form flame and smoke tight joints between these basic members. This collapsible camp stove is adapted to house all the flue sections and other stove accessories therein when in the collapsed mode. The collapsible camp stove assembly includes a bottom, a top and sides; the bottom and the top have peripheral flanges cooperatively engaging each other and forming an enclosure for the sides and other members when the stove is collapsed and the sides form lap and groove joints with the bottom and the top when the stove is installed.
