A flexible-walled, tubular, collapsible container for liquids is disclosed of the type having a head portion with access means, and a tail portion with a sealed line joining sides of the container into a sealed end. In accordance with this invention, the sealed line occupies a recess defined in the sealed end by the flexible container walls. As a result of this, outwardly directed shock, created for example when the filled container is dropped, is absorbed by the walls of the recess, to protect the sealed line from rupture. Accordingly, the sealed end of the container of this invention exhibits increased strength and rupture resistance. |
