Abstract
Improvements in the manufacture of bags, formed by an inner bag in the form of a sheet and an outer protective bag, characterized by the fact that it forms at the lower ends of both the inner and outer bags, in all its width and at its upper ends a connecting seam in a part of the width, and a filling opening in the remainder of the same, whose filling opening constitutes the mouth, inclined skewed 45ยบ, of a valve that closes by itself when the bag is filled and it is obtained by incising, bending and inserting the material of the bag, where the inner and outer bags are made of different materials, not suitable for the same type of connection seam, the two inner bag connection seams are closer to the central part of the bag than those of the outer bag, and the connecting seam of the upper end of the inner bag is shorter than the difference between the length of the bag upper, shortened edge of the outer bag and the length of the inner bag valve and longer than the difference between the length of the shortened upper edge of the inner bag and the length of the valve of said inner bag.
