RoGer Helium Bottle for Balloons

Disposable  helium cylinder  for filling balloons.
Cylinder capacity approx. 0.21 m3.
Enough to fill:
approx. 30 latex balloons, size 23 cm (9 inches),
approx. 14 latex balloons, size 30 cm (14 inches)
approx. 9 - 10 foil balloons, size 48 cm (19 inches)
approx. 2 foil balloons 86 cm, e.g. numbers (34 inches).
The above amounts do not add up and should be treated separately.
Helium balloons should be filled at room temperature (from 18 to 25 degrees C) due to the thermal expansion of the gas (helium increases in volume at higher temperatures and decreases at lower temperatures).

It is best to fill balloons 1 - 3 hours before the party.

Remove the helium cylinder from the packaging.
Open the valve by turning the green knob counterclockwise.
Stretch the balloon onto the black tip of the reducer (rubber) so that the neck of the balloon fits snugly to the outlet tip.
While pressing the balloon tightly, press the nozzle down and the helium filling will begin.
When the balloon reaches the right size, stop pressing - the inflation will end. Remove the balloon tip from the reducer.
Tie the balloon.
Close the valve.
Remaining time of helium in foil balloons: about 4 days.
Remaining time of helium in latex balloons: approximately 5 - 7 hours.
Latex balloons filled with helium can float for up to several days,  for this purpose a sealing gel must be used.
