Tamper evident, hygienic "sleeve" shields bottles from contamination
Back in the 1950s at my grandfather's home, I can recall the
original glass bottles and metal "tilters" that were used for
dispensing fresh spring water from bottle to pitcher. If it were only so simple
We have come a long way in the last 50 years--trips to Mars,
cell phones, microwaves, computers and liter PET bottles. Yet in an industry
that effects many of us, the 5-gallon bottled water industry has seen little to
no new innovations. Innovation is available, just not being demanded by the
Changes from the heavy glass bottles to the new
polycarbonate and PET bottles have evolved for convenience sake. Even with the
percentage of "leakers" and ensuing damage claims, the benefits have
outweighed the problems. Tilters have upgraded to open top dispensers to give
us cold or hot water at the push of a lever. Open top dispensers comprise 95 percent
or more of the industry and were enhanced with the introduction of the
"Water Guard" cap in the early 1990s. Yet with these changes, are
consumers better off than they were 50 years ago when it comes to drinking pure
Presenting the case in hand, every time we open the sealed
top of the bottle container, whether or not we remove the cap or displace a
plug, we subject the contents to undesirables such as bacteria and dirt.
What makes the water so pure--no chlorine, ozone or any
combatants, only defenseless, pure water--also is what makes it so susceptible
to foreign invaders. Think of the steps a bottle goes through.

is stacked at home or in the office rack.
is left for days or weeks to collect fallout from whatever kind of atmosphere
it is sitting in before it finally is used.
is picked up again for delivery to the water dispenser.
Each time that bottle is handled, the cap and outside of the
bottle are likely to get dirty.
The hands that carried the bottle (most times right at the
neck) before it is delivered to the customer have diverted sneezes, opened
doors, politely shaken the hand of who knows who and may not have been washed
before leaving the bathroom. They have deposited colonies of invaders on the
bottle's outside. Bacteria and dirt, among other things, lie waiting to find a
host home in which to multiply. Meanwhile back at the ranch (or rather the
dispenser) the last batch of invaders have been multiplying, waiting for
reinforcements to arrive, which they always do.
Open top containers tend to provide the most likely scenario
for invasion. The entire water reservoir is open to contamination as soon as
the bottle is tipped upside down and placed on the cooler for dispensing. The
first sound of water and air exchanging places is the assurance that the neck
and shoulder areas are being gently rinsed off to allow whatever was on the
outside of the bottle to drip off into the inside of the cooler reservoir.
It is up to you to provide your customers with the proper
sanitization for their water coolers. The bottle that you deliver should not be
covered with dust, fallout, germs and "hand grime."
Water guard or similar product dispensers, for example, may
be an advantage because they allow the tipping and placement of the bottle
without spilling water on the wall or carpet. One can even remove the bottle
while it is half full and not spill a drop. It is ideal for the bottler to know
that when the bottle is returned for refill, the cap is still in place, sealed
with the inner plug, reassuring him that no foreign substances such as pennies,
gasoline, urine or fertilizer have been introduced. (It's amazing what people
do with empty 5-gallon water containers.)
However, this solution poses a problem. When you get a
chance, look down in the bottom of the Water Guard reservoir cup. Notice the
shallow puddle of not-so-inviting liquid. (It's the one with the
"squigglies" floating around in it.)
The main issue with the water guard product is the residual
water in the bottle-holding cup that can sit, sometimes for months, growing new
breeds of invaders that cling to the cap as it is withdrawn with the bottle, dripping
back to the center of the cap, directly onto the probe being introduced into
the "fresh" bottle. Whatever was growing in the puddle, now is
growing unchecked on the probe and in the drinking or spring water the customer
just paid good money for.
Tufts University's Diet & Nutrition Letter
style='font-style:normal'> reported that many coolers may be nurturing high
levels of bacteria that could cause nausea and diarrhea.1 Scientists checked
the bacterial count from 10 water dispensers at Boston's Northeastern
University and found that water from each dispenser had bacteria counts
reaching at least 2,000 potentially harmful organisms for every milliliter of
water or four times the limit recommended by the government. Counts exceeded
2,000 times the government's recommendation in coolers used on a frequent
basis. The problem does not stem from the pure bottled water, but instead it
appears that the invaders from the outside of each new bottle of water multiply
as they are added to the dispenser system.
Using a product such as the Sanisleeve(TM)--which is added
just after the filling and capping of the bottle at the bottling facility while
the bottled is still clean--can create that barrier needed to block
contaminants when changing bottles. This product provides a tamper evident seal
and is a hygienic sleeve that covers the outside cap, neck and shoulder of the
bottle, shielding it from airborne contaminants, hands of any sorts, dust, dirt
and the like.
This patented product will carry contaminants away just before
the bottle is used.
The sleeve remains intact, shielding the outside of the
bottle until the customer removes it, just like a tamper evident seal on any
other market item you purchase such as Tylenol. Bottlers have the availability
of the sleeve at present, and as consumers become aware of existing problems
they can request it as a solution towards the problems.
Cleanliness is definitely next to godliness when it comes to
water coolers. Unlike our European friends who have quarterly dispenser
sanitation, the United States has no regulated cleaning program.
Let your customers know that they can
for the Sanisleeve(TM)
you to clean the dispenser, which could result in having a new one delivered
and swapped out with the existing dispenser, or
the job themselves.
Customers should follow the distributors' instructions
regarding the cooler reservoir. Use the water/bleach solution and method
suggested for cleaning and be sure to run the sanitizing solution through the
holding reservoir as well as the faucets to purge all parts that come in
contact with the water he is drinking.
All in all, cooler sanitation is vital to the hygienic
safety of the water we consume. There needs to be a conscientious effort made
by the distributor to do all that is possible to keep the bottle as well as the
dispenser a safe haven for the water he works so hard to keep pure. The
Sanisleeve(TM), clean bottles and good cooler hygiene will make a complete,
safe delivery of pure water for the customers' enjoyment. style='mso-tab-count:1'>
