Abstract
A flexible tubular vial is plugged at one end. The plug is pulled out to open the one end and define a gap between the open end of the vial and the plug. A sleeve bounds the gap. The sleeve has a rib as does the vial (or an intermediate component) that block each other so as to limit relative movement of the plug between a retracted relative position that plugs the open end and a cleared relative position that clears the open end. By squeezing the vial, contents of the vial are urged out through interstices in the plug. The contents may be a teeth whitening composition gel that urges out through interstices in the plug to a brush-like applicator to be applied to teeth or may be a topical medicine to be applied to skin.
