ABSTRACT:
A method for making a capture and containment bag having a large reservoir that tapers into an elongated conduit wherein the reservoir is formed by joining two heat sealable panels along their side edges to form a linear end edge and then joining such linear end edge to the flared end of a narrow heat sealable strip with a pair of longitudinally extending side edges of such narrow strip then joined to form a conduit. The two panels are then joined along the remaining side edges as a continuation of the joining of the sides of the narrow strip to form a bag with a large storage reservoir and a narrow elongated discharge control conduit.
