A flexible Bolda formed by a sheet of flexible material with an Opening that defines a plane.In addition to a region with higher extension Shaft perpendicular to the palno against external forces and a Lower extension with an Axis parallel to the plane of the opening to ForcesExercised by the content.

摘要

The present Invention provides a flexible Bag comprising at least one sheet of flexible sheet material assembled to form a semi enclosed container with an Opening definedFor a Periphery. The opening defines a plane of the opening, and the Bag has an Opening adjacent to the Upper region and a Lower region below the Upper region.The superior region has a preferential extension Axis perpendicular to the plane of the opening that allows the Upper region expands in response to an externally Applied ForceThe Bag,While the lower region has a preferential extension Axis parallel to the plane of the opening that allows the region to expand in response to the forces exerted by the content denWithin the bag to provide an increase in the volume of the Bag above the Bag, therefore exhibits increased stability in use and is easier to close.
