A device for applying a product may include a container configured to
contain a product, a duct associated therewith, and an applicator. The
applicator may include a side wall, a substantially closed first end
defining an application surface, and an open second end. The duct may
define an axis and a passage in communication with the container. A
portion of the axial length of the applicator may be located around the
duct. The applicator may be configured such that, when the applicator and
the container are coupled together, at least one cavity is formed between
a free end of the duct and an internal surface of the applicator, and at
least one portion of the applicator has a thickness along a direction of
the axis of the duct that is less than the thickness of the side wall in
a direction substantially perpendicular to the axis of the duct.
