Abstract
Abstract A cardboard coffin for use at parties or similar occasions which is formed from a plurality of corrugated cardboard blanks having appropriate score lines formed therein to facilitate folding comprising a bottom having a central body portion having a perimeter in the shape of a coffin and defined by a plurality of score lines. A plurality of integral rectangularly shaped portions extend upwardly from the perimeter and have an angular relationship with the central body portions of about 90 degrees wall portions are formed from two cardboard blanks having score lines so that the two cardboard blanks may be folded along the score lines to form two opposite side wall portions and overlapping top and bottom wall portions which are secured together by tape. The integral rectangularly shaped portions of the bottom are secured to the adjacent surfaces of the wall portions by tape. If desired, a lid having a central body portion having a perimeter in the shape of a coffin defined by a plurality of score lines with a plurality of integral rectangularly shaped portions extending from the each of the score lines is provided. One of the integral rectangularly shaped portions is secured to a portion of one of the side walls to hingedly mount the lid for movement between closed and opened positions. All of the other integral rectangularly shaped portions are adapted to be folded upon themselves and be secured together so as to have an angular relationship with the central body portion of 90 degrees so that the wall portions may be received with the configuration defined by all of the other integral rectangularly shaped portions.
