Cooling Bottle cover "bicool"
We can always drink cold water even if under the hot weather,
it supplied by the cooling bottle cover "bicool".
Keep water temperature under 8degrees from the outside temperature.
1. Active Cooling (not Keeping cool) 2. The effect continues all the time.
(It is necessary to retain water) 3. You can use your original bottle and bottle gauge. (thin and light weight) Material: Polyester/Nylon
Made in JAPAN patent applied for
Sunlight is interrupted in surface shading / ventilation layer.
A wind through shading / ventilation layer and evaporates the water of
Keeping Water layer.
Water evaporates in the shade and cools a bottle.
Putting on a bicool cooling bottle cover, it can
keep a drink of the inside coldness such as the tap water.
When the water in the keep water layer evaporates,
it take evaporation heat and cool off.
If only wrapping wet cloth with the bottle, it does
not get cold very much because of direct rays of the sun.
Bicool cooling bottle cover have cloth for hollow
knit around the keeping water layer, and it shut out the direct rays of the sun
and take evaporation heat to through wind.
Therefore bicool can keep temperature having lower
8-12 degrees than a normal bottle.
(temperature is depend on a condition.)
By the experiment, at the riding condition, the normal bottle became a maximum of 35 degrees.
On the other hand bicool bottle can keep 26 degrees.
(At outside temperature 34 degrees)
The normal bottle became rise 38 degrees when
bicycle stopped. Bicool bottle keep 26 degrees even if bicycle
stopped. This difference of temperature feels drinks hot
water, or drink normal water.
The water in a keep water layer gradually
evaporates Please retain water at the time of a break,
approximately two hours/once.
It dose not get so wet if you have it by hand,
because there is cloth for knit around the cover.
TEST result: Outside temperature is 34 degrees. Normal bottle is 38 degrees. Cooling bottle is 26 degrees. (maximum temperature difference is 12 degrees)
Why to develop bicool
When I participated in TOUR DE NOTO 400 in 2012.
It is a competition to run the 400km in three days.
As for the highest temperature, 36-37 degrees
continued with three days.
It becomes like the hot water of the bath
immediately, even if I put ice and water into the drink bottle.
I drink it, there is no refreshment.
I want to take a cold drink, but the vending
machine on the course has few numbers, and sell out the almost of vending
machine of the place where it is easy to stop at.
At that time I intended to make the cover which
took evaporation heat, and always cooled the bottle.
I thought that it got cold even if wound up a wet
towel, but it may evaporated immediately, and an effect did not continues long
time, and direct rays of the sun hit it, and the temperature would not get cold
Therefore it is bicool bottle cover, it apply the method to take evaporation
heat away with high efficiently, through wind to the water keeping layer
as the shade condition.
Let water soak into a cover during a run once in
approximately two hours. Then it can keep cooling effect continuously. I think that I take a rest around every 2 hourst
and settle supply and a restroom with the real long-distance run. Let water soak into a cover in the occasion.
Bottle cover “bicool" usage
Let water soak into a cover.
Let put a drink into the drink bottle before
running, and water soak into a bottle cover.
The preparations are only these.
It put in a bottle gauge.
The cloth for cover thickness is around 2mm.
It may be little hard to be contained in some
gauges, but there is elasticity in a bottle and a gauge, so please push and
Frequency of the water soak into a cover is
approximately one to two hours.
During a run, the water of the bottle cover
gradually evaporates and cools the inside.
Let water soak into a cover at the time of a break.
I think that around each 1-2 hours enough.
