Container with pump that mixes liquid and air to discharge bubbles

Abstract

A container with a pump is provided that includes a container body with a neck portion and a pump for discharging bubbles that is provided on the neck portion. The pump includes a cylinder for air and a cylinder for liquid provided in a concentric arrangement. An attaching trunk is provided on the neck portion that holds a flange of the cylinder. A piston head passes through the attaching trunk in a state that allows upward and downward movement. A hollow, cylindrical stem having open ends is received within the cylinder. The upper part of the stem is connected to the piston head and a slidable circular first piston is provided on the lower part of the stem. A second piston is provided on an external surface of the stem and is only capable of slight upward and downward movement. A liquid discharge valve is arranged on the stem and a bubbling member is received between the liquid discharge valve and the nozzle. The pump also includes a vapor-liquid mixing chamber, an air passage and a liquid passage. A coil spring energizes the stem and a locking mechanism prevents movement of the piston head.
