ABSTRACT:
This disclosure pertains to a hot cap fabricated from two precut sheets of semi-rigid plastic or paper stock material. Each sheet resembles an isosceles triangle with the apex portion removed along a line parallel to the base of the triangle. Two flaps are formed along a horizontal fold line at the narrow end of the triangle, separated by a central knotch having a vertical axis. A series of holes are placed parallel and close to the base line. The four flaps are folded together in locking position in similar fashion to a conventional cardboard container and have ventilation holes passing through the flaps in each corner of the horizontal surface formed thereby. The holes adjacent the base line are utilized for securing purposes and ventilation, if so desired, when the lowermost edges are formed into generally circular shape and are depressed into the earth. The flaps are readily opened or closed providing a variable degree of access for ventilation and watering purposes.
