ENVASE Y PROCEDIMIENTO PARA SU LLENADO

Envase, que comprende una bolsa de una hoja de material flexible que en su estado plano comprende dos paredes laterales opuestas (2) substancialmente en contacto entre sí, estando selladas dichas paredes laterales firmemente a lo largo de bordes laterales opuestos (5), comprendiendo también la bolsa una pared inferior (3) que se pliega doble y que tiene dos campos (31) enfrentados entre sí alojados entre las partes inferiores de las paredes laterales (2), estando las partes de los bordes finales de la pared inferior sellados juntos, estando los bordes laterales de la pared inferior, por lo menos en la proximidad de la línea de plegado (32), unidos a las paredes laterales en sus bordes laterales (5), caracterizado por el hecho de que una cuerda de material (4) se conecta a cada pared lateral (2) en su borde inferior (21) cuando el envase está en estado plano, y por el hecho de que la cuerda de material se dispone para conectar con el borde de la pared inferior del envase lleno cuando se apoya sobre una superficie. A package comprising a bag of flexible sheet material which, prior to being filled, is laid flat and comprises two opposing side walls ( 2 ) substantially in contact with each other, which side walls are tightly sealed along opposing side edges ( 5 ), the bag also comprising a bottom wall ( 3 ) which is folded double and has two fields ( 31 ) facing each other received between the lower parts of the side walls ( 2 ), the parts of the end edges of the bottom wall being sealed together. At least in the vicinity of the fold line ( 32 ), the side edges of the bottom wall are joined to the side walls at their side edges and a string of springy, elastic material ( 4 ) is connected to a respective side wall ( 2 ) at its lower edge ( 21 ), along substantially the entire length of the lower edge of the side wall when the package is in its flat state, and the two material strings are separated from each other. The package is filled by inserting a substantially leaf-shaped pouring mouthpiece into the flat neck of the pack-age and introducing liquid through the mouthpiece, after which the neck of the package is sealed. The packages may be joined together in a coherent chain of packages attached to each other at their side edges.
