Abstract
An adjustable adapter includes two arms, each having an axis, a surface substantially normal to the axis, wherein the surfaces of the arms face each other, an end and a passageway for fluid communication between the end and the opening, wherein one of the arm ends is for connection to an inlet of an applicator and the other arm end is for connection to an outlet of a container, and a fastener for pivotally coupling the arms. One of the arm surfaces is provided with a groove in fluid communication with both arm openings. The groove is sealed to prevent fluid from leaking from between the surfaces. When the fastener is in a rotation-resisting mode, the fastener forces the surfaces of the arm toward one another sufficiently to increase friction and resist rotation therebetween, and when the fastener is in a rotation-permitting mode, the fastener releases the surfaces sufficiently to decrease friction and permit rotation therebetween.
