摘要: A container for use in bulk transporting chemical goods, grains and the like, comprises a sack body in the form of a rectangular parallelepiped prepared from a cylindrical blown film. The container has a feeding end, a discharging end and a ventilating end. Enhanced pressure-resistive strength is obtained by improving the ventilating end-mounted design so as to have a specific shape. In one embodiment, a line slit is formed through the sack body, a cylindrical film is inserted into the slit, and the sack body and the cylindrical film are bonded to each other in line along the periphery of the slit so that the bonded corner spots, of the sack body and the cylindrical film, located at both ends of the slit, has a shape of a convex curve, for example, a circular shape or a ringed shape. This bonded structure makes it possible to deconcentrate pressure applied in using and filling the container without concentrating on the corner spot to prevent generation of pinholes and sack burst of the container.
