Abstract
A piston-cylinder liquid sprayer of long spraying time and simple construction has a long piston stroke and is adapted to spray liquid steadily without loosening. An erecting wall having an upper end portion engaged with an upper portion of a cylinder is attached to the outer surface of a container body neck portion. An erecting guide trunk is connected to the lower end of the erecting wall, and surrounds the erecting wall at a constant distance. A sliding trunk moves a piston upwardly and downwardly and is fitted into a gap between the erecting wall and the guide trunk. The sliding trunk is guided by the guide trunk, allowing the sliding trunk to be stably moved upwardly and downwardly, even if a longer stem is used.
