ABSTRACT:
A method and apparatus for coating the interior edge of an open ended container with an adhesive strip or band. An open rim of a container abuts a flat surface on an adhesive applicator head. A flowable adhesive passes radially outwardly and thence axially, between the inner container rim surface and a part of the head, to deposit a band of adhesive, such as a hot melt adhesive, on the container inner surface. The flat surface of the head functions both to position the container relative to the head and to form a seal to thus permit adhesive coating up to the edge of the open container end.
