Abstract

An elongated strip of plastics in a flexible bag guides liquid in the bag to the bag outlet when a vacuum is applied to the outlet. The flow guide has structure which forms a plurality of interconnected spaces that in turn form flow paths in combination with the bag collapsing walls The guide can take many forms including a net-like configuration, a pattern of alternate recesses and projections on each face of a strip. woven material, open cell sponge like material hed ran­ domly oriented fibres, material having spaced air bubbles between strips of plastic, or other such structures that can form flow paths in combination with bag wall Also disclosed is a stretched flexible tube having a spiral slot formed therein to serve as a flow guifle Methods of making the bags and guides are further disclosed.
