Squeeze container with sonically welded flexible tubular body and bottom cover

摘要

A squeeze container has a flexible tubular body and a separately molded bottom cover. The bottom cover has an axially facing continuous groove in which the open end of the tubular body seats with the end surface of the tube abutting the bottom surface of the groove. A radially outwardly extending flange spaced axially from the open end of the container has a bottom surface which abuts a top surface on a lip extending radially outward from the groove in the bottom cover. A tubular extension on the bottom cover radially inward of the groove has an outer surface which abuts the inner surface of the tubular body. Sonic energy directors in the form of continuous pointed ribs effect sonic welds between each of the sets of abutting surfaces to hermetically seal the bottom cover to the tubular body.
