Abstract
Perfection in sacks and bags of thermoplastic material, characterized by having an opening, provided with a valve, in the wall of said containers, near one end of said wall, and a flap attached to the wall of the container, which covers the opening and it provides a filling passage between the wall of the container and the flap, through which the container can be filled, the dimensions and arrangements of the opening and of the filling passage with respect to the wall of the container, are such that, when the latter closed, is filled with a granular solid and inverted in such a way that the content exerts pressure on the passage, virtually no content escapes through the passage.
