an improved multipack container is provided for accommodating a plurality of cathode ray tubes during transportation and storage . the altered construction includes basic top and bottom rigid closure members formed of flame retardant plastic material . positioned peripherally therebetween are two substantially u - shaped edge - oriented areal support members , such being opposingly located between the superjacently related ledges of the respective closure members . since the forward portions of the u - shaped supports do not meet , a beneficial window opening is provided on either side of the multipack structure . internal supportive and protective structural means are predeterminately located between the closures in a manner spaced from the peripheral support members . upon assembly of the multipack container and placement of the tubes therein , a tight covering of plastic material is applied to contiguously encompass the complete multipack to provide a unitized assemblage . the reinforced construction effects a firmly secured multipack having flame retardative features , improved structural rigidity and enhanced protective characteristics .
