A neckless funnel packing case for a CRT(Cathode Ray Tube) is provided to simply bond a bearing wall and an inner wall without special tools by fitting support pieces formed at each part of a body and the bearing wall into support piece insertion grooves. Plural funnel body insertion grooves have plural skirts(12) closely contacting with a funnel body bent and extended from the inside of a lower plate of a body and placed on the inside of the lower plate. Plural inner wall underside support piece insertion grooves(13) with the predetermined width and length are fitted by first and second inner wall underside support pieces(27,47,39,59) contacting with bent lines of outer walls(21,31,41,51) extended from the outline of the lower plate. Outer wall flange parts(34,54) with the predetermined length are bent and extended from the outer peripheral parts of the left and right sides of the first outer wall. First upper plates(32,52) with the predetermined width are extended from the upper and lower peripheral parts of the first outer walls. One or plural second bearing wall insertion grooves(36,56) are extended from the inside of first inner walls(33,53) and fitted by second bearing walls(71) to contact the second bearing wall and the lower plate formed between the funnel body insertion grooves formed at the left and right sides in order to prevent contact between the adjacent neckless funnels placed on the inside of the lower plate.
