<p>ORAL HYGIENE METHODS AND APPARATUS Oral hygiene methods and apparatus for producing a liquid jet by pumping liquid through an inlet in a pump housing from a reservoir employ an arrangement in which the reservoir in an inverted position serves also as a cover for the pump housing or inlet. For optimum compactness, the inlet is provided laterally at the pump housing. In particular, the inlet may be located in a side wall laterally of a part of the pump housing serving as a first supporting base in an upright position thereof, and the pump housing has a second supporting base laterally of the first base. In practice, the pump housing is laid on its side or second supporting base, whereby the inlet comes to face upwardly. Liquid is then pumped from the reapplied reservoir while the pump housing is lying on its side.</p> |
