Abstract:
1. A small-sized hand-operated spray pump comprising: a cap having an spray nozzle, the cap being coupled to a shaft such that the cap communicates with the upper end of the shaft, the cap being provided at the lower end or side thereof with coupling extensions coupled to the upper end of a housing such that the coupling extensions are vertically reciprocated; the housing constructed in an elongated cylindrical structure forming the external appearance of the pump, the housing being provided at the upper end thereof with a coupling guide, to which the coupling extensions of the cap is coupled; a container mounted at the lower part of the housing, the container being constructed in a plate-shaped structure containing content (fluid); a closure fixed to the outer surface of the housing, the closure being constructed in a symmetrical wing structure in which the upper part of the container is in tight contact with opposite wing parts of the closure; the shaft having a horizontal channel communicating with the inner space of the housing and a vertical channel communicating with the horizontal channel, the shaft being vertically movable along the inner surface of the housing, the shaft being connected to the lower end of the cap; a piston mounted to the shaft for elastically opening and closing the horizontal channel; a compression spring mounted between an inlet port formed in the inner lower part of the housing and the shaft for providing a restoring force to the shaft at the time of pumping; a ball disposed at the inner lower side of the inner space of the housing for opening and closing the inlet port of the housing at the time of pumping; and a case member coupled to the lower part of the coupling guide, the case being constructed in a plate-shaped frame structure including frames protecting the container while the frames are spaced a predetermined distance from the outer circumference of the container.
