Abstract

Improved envelope, which is specially designed for inserting machines designed to open the envelope to introduce the corresponding documents and adopting the development of the envelope a configuration that can be considered as rectangular in which a determinative rectangular area of the anterior face is defined, another determinative rectangular area of the back face, as well as respective lateral flaps emerging from the transverse edges of the anterior face itself and a closing flap that is derived from the longitudinal edge of such anterior face opposite the edge from which the face is derived after the envelope itself, it is essentially characterized in that the constitutive extension of the back face of the envelope is slightly shorter than that corresponding to the anterior face, as a consequence of the lateral edges of such constitutive extension of the posterior face presenting at the beginning two short inclined sections of converging shape entity; with the particularity that the longitudinal and free edge of such rear face adopts a very open "V" profile determinative of an angular neckline, which is complementary to the profile of the longitudinal and free edge that has the corresponding closing flap that emerges of the other longitudinal edge of the front face, said closing flap having its convergent inclined lateral edges as well as the corresponding end edges corresponding to the lateral flaps emerging from the transverse edges of said front face of the envelope.
