Squeeze container with sonically welded flexible tubular body and bottom cover

A squeeze container comprising:

• a flexible thermoplastic tubular body with an open bottom end having a bottom edge surface, said tubular body having a flange with an axially facing bottom surface extending radially outward from an outermost side wall surface of the tubular body and axially spaced from said bottom end, a thermoplastic bottom cover enclosing the open bottom end of said tubular member and having an axially facing groove in which said bottom end of said tubular body seats with said groove having a bottom surface abutting the bottom edge surface of the tubular body to form a first pair of abutting surfaces and a side wall surface abutting an inner side wall surface of said tubular body to form a second pair of abutting surfaces, said cover having an axially facing top surface adjacent to and radially outward from said groove which abuts said bottom surface of said flange on the tubular body to form a third pair of abutting surfaces, and sonic energy director means on at least one abutting surface of at least one of said pairs of abutting surfaces which concentrates applied sonic energy to fuse said at least one pair of abutting surfaces together thereby hermetically sealing said bottom cover to said tubular body.
