Air valve

Abstract

This article is an air valve for injecting air into a sealed vinyl appliance such as a floating bag and discharging air from the vinyl appliance. As shown in Reference Figure 1 representing the usage state, the injection of air into the vinyl appliance is carried out by creating a gap between the valve body portion and the valve portion by depressing the valve portion by, for example, the pressure of air sent from an air injection pump or the like, or by being pushed at the tip of the air injection pump nozzle, with the lid removed. The sealing of the air put into the valve body portion is carried out by causing the valve portion to abut against the inside of the valve body portion due to the air pressure inside the vinyl appliance and sealing the lid at the vent of the valve body portion. Incidentally, as shown in Reference Figure 3 representing the usage state, the discharge of air from the vinyl appliance is carried out by creating a gap between the valve body portion and the valve portion by pushing the valve portion against the air pressure inside the vinyl appliance with the protrusion formed on the lid with the lid removed.
