Article comprising an enveloping structure

An article comprising an at least partially transparent enveloping structure, the structure comprising three pieces of self-cohesive, pliable plastic sheeting which are substantially coextensive in a first planar dimension thereof and are not coextensive in a second planar dimension thereof normal to the first planar dimension, a first of the pieces having mutually opposed lateral edges coextensive with the first planar dimension, the second and third pieces each having a lateral edge attached to a respective one of the lateral edges of the first piece, the second and third pieces each being smaller than the first piece in the second planar dimension and each having a free lateral edge, the combined second planar dimensions of the second and third pieces being greater than the second planar dimension of the first piece whereby the second and third pieces have mutually overlapping lateral portions contiguous with their respective free lateral edges, the first, second and third pieces thereby forming an enveloping structure, the pliability of the sheeting permitting the overlapping portions of the second and third pieces to be manually peeled away from each other thereby to provide access to the interior for insertion or removal of decorative or information conveying matter and then to be mutually overlapped again and the self-cohesiveness of the plastic sheeting causing the overlapping portions to cohere sufficiently to remain sealed when not being subjected to said manual peeling, at least one piece of the plastic being transparent, said at least one piece being selected so as to permit viewing of decorative or information conveying material in the enveloping structure.
