How should you fill the OLKO hot water bottle and prepare it for use? — Rubber heating bag 2 - OLKO

Before filling, make sure the stopper of the hot water bottle is unscrewed and the neck is clean. Fill the bottle with water from the tap or a kettle, but not boiling water: the water should be warm and comfortable to the touch, so as not to damage the material or create a risk of burns on contact with the skin. Fill it no more than two thirds full, as this lets the bottle take the shape of the body better and reduces pressure on the seams.

After filling, carefully release the air from the bottle by squeezing it gently until water appears at the neck, then screw the stopper on tightly. Turn the bottle neck down and check that there is no leak. Before applying it to the body, wrap the bottle in a towel or a cover, as this softens the heat and protects the skin from direct contact with a hot surface.

A volume of 2 litres allows you to use the bottle for the legs, lower back or stomach, or simply keep it nearby in bed. After use, drain the water, slightly open the stopper and store the bottle flat and unfolded, as this prolongs the service life of the material.
