Nasal rinsing cap for bottles

A nasal rinsing cap for bottles comprising a body part, which is mountable to a mouth of a bottle and has a cylinder-shaped vacuity in it for a threaded part of the mouth of the bottle, and a tubular vacuity extending from the cylinder-shaped vacuity through the body part to an end of the body part for discharging liquids from bottles connected to the nasal rinsing cap when it is used,

• wherein the tubular vacuity is equipped with a liquid valve to facilitate a flow of liquids through the cap out of the bottle as well as to prevent any backflow of liquids back into the bottle;
• and the body part is equipped with an air valve to allow an entry of air into the bottle upon occurrence of negative pressure in it as well as to prevent any outflow of liquids when the bottle is turned upside down or squeezed;
• and a top part, which can be removed or opened, is positioned on the body part, the top part comprising a tubular vacuity which runs through it, the tubular vacuity of the top part beginning from a point adjacent the tubular vacuity of the body part, extending through the top part and opening at a tip of the top part, wherein the top part is configured so that its tip can be inserted in a nasal cavity of the user, and a pressure region has been formed on the top part to close the liquid valve by putting pressure on the pressure region of the top part by means of a finger, and
• wherein the top part comprises a cylinder-shaped element, which connects the pressure region with the liquid valve so that when pressure is applied on the pressure region, the liquid valve closes.
