I just found this info in a press release from Playtex.  Coming soon to a
baby near you....

< In Infant Care, the Company announced new products in each of its
major infant care segments.  In the disposable feeding segment, the
Company is launching a 4 ounce version of its DROP-INS sac along with
a proprietary DROP-INS holder and two new disposable nipples to
complement its existing assortment of nipples. In the pacifier segment,
Playtex is
introducing a new one-piece silicone pacifier under the trademark
SAFE'N SURE.
          The Company also announced a revolutionary new hard bottle
feeding system called AVANCE.  Unlike conventional hard bottles which
are vented near the nipple, this system incorporates a patented air
vent on the bottom of the bottle that eliminates air bubbles that
form at the top of conventional bottles as babies feed.  In addition,
the bottom of the bottle can be unscrewed from the body of the bottle
for easier and more effective cleaning.>
