The sprayer has a notch (50) formed in a suction tube (5) whose upper end passes through a lower hole of a screw (313) of a support of a container cap (4). A manual pump (1) e.g. rectangular hollow spherical shell, is connected to a connector (2). An air valve (111) is formed on a side of a periphery of an air intake (1111) to release exterior air in an air chamber (11). An air mouth (112) is formed in periphery of the manual pump on an opposed side to direct pressure of air outside the chamber. A mounting channel (113) is formed around the port of mouth to support a part of the connector. The manual pump is made of an elastic material among a group of rubber and elastic plastics. The suction tube is composed by metal and plastic materials. |
